    2009-01-01

    Background Concern about the use of endangered and threatened species in traditional medicine escalated as populations of many species plummeted because of poaching for the medicinal trade. Nigeria is known for a long and valued tradition of using wild animals and plants for medicinal purposes. Despite this, studies on medicinal animals are still scarce when compared to those focusing on medicinal plants. Utilisation of wild animals in traditional Yorubic medical practices was indiscriminate as it involved threatened species. By touting the medicinal properties of these species, traditional medicine fuel continuing demand, thereby subjecting such species to further threats. This paper examined the use and commercialisation of pangolins for traditional medicinal purposes amongst the Ijebus, South-western Nigeria, and the implications of this utilisation for the conservation of this species. Methods Traditional Yorubic medical practitioners (tymps) (16) and dealers in traditional medicinal ingredients (56) in public markets in Ijebu province, Nigeria, were interviewed using open-ended questionnaires. The dynamic stock movement of pangolins in the stalls of dealers was also monitored to determine quantity of pangolins sold into the traditional Yorubic medicinal practices. Specific conditions treated and the parts required were also documented. Results A total of 178 whole pangolin carcasses were sold into traditional medical practices. Above 55% of respondents had just primary education, over 90% of respondents were not aware of either the conservation status of this species or the existence of any legal machinery regulating its trade and utilisation, while 14% admitted to giving contracts to hunters for deliberate search for this animal when needed. More than 98% of respondents have no other means of livelihood. The trade was female dominated while the healing practice had more males. Pangolins were used in various preparations to treat a total of 42 conditions

    We analyzed sera collected during 1987 and 1988 from 385 healthy business employees of both sexes, of Ogun state in Nigeria, for antibodies to the 3 human retroviruses HIV-1, HIV-2 and HTLV-I. No serum was HIV-1 positive, 1 was HIV-2 positive and 2 were HTLV-I positive. A few sera were false-positive in the antibody screening tests which preceded the confirmatory antibody tests. In the confirmatory tests, we found that in the HIV-1 Western blot test 1 serum reacted only with the HIV-1 gag protein p17, and 2 sera reacted only with the HIV-1 pol proteins p64, p53 and p31. None of these reactivities fulfill internationally accepted criteria for HIV-1 seropositivity. We conclude that HIV-1 was rare in the study population and that HIV-2 and HTLV-I are present at a low frequency. The false positive serological reactions observed are similar to those described previously from Africa and elsewhere. The findings emphasize the importance of routinely testing blood donations for antibodies to these retroviruses in Nigeria.

    Rare earth elements in our environment are becoming important because of their utilization in permanent magnets, lamp phosphors, superconductors, rechargeable batteries, catalyst, ceramics and other applications. This study was conducted to evaluate the level of rare earth elements (REE) and the variability of their anomalous behavior in groundwater samples collected from Lagos and Ogun States, Southwest, Nigeria. REE concentrations were determined in 170 groundwater samples using inductively coupled plasma-mass spectrometry, while the physicochemical parameters were determined using standard methods. Lagos State groundwater is enriched with REE [sum REEs range (mean ± SD)]; [0.365-488 (69.5 ± 117)] µg L(-1) than Ogun State groundwater [sum REEs range (mean ± SD)]; [1.14-232 (22.6 ± 41.1)] µg L(-1). Boreholes are more enriched with REEs than wells. Significant (P < 0.05) positive correlation (R = Pearson) was recorded in Lagos State groundwater between sum REEs and Fe (R = 0.55). However, there were no significant correlations between sum REEs, pH (R = 0.073) and HCO3(2-) (R = 0.157) in Ogun State groundwater. Chondrite-normalized plot shows that Lagos groundwater exhibits positive Ce anomaly, while Ogun State groundwater does not. The source of REE in Lagos State may be from the ocean and leaching from wastes dumpsites, while the source in Ogun State groundwater may be from the rocks.

    Background: Tetracycline is one of the most frequently used antibiotics in Nigeria both for human and animal infections because of its cheapness and ready availability. The use of tetracycline in animal husbandry could lead to horizontal transfer of tet genes from poultry to human through the gut microbiota, especially enterococci. Therefore, this study is designed to identify different enterococcal species from poultry feces in selected farms in Ilishan, Ogun State, Nigeria, determine the prevalence of tetracycline resistance/genes and presence of IS256 in enterococcal strains. Materials and Methods: Enterococci strains were isolated from 100 fresh chicken fecal samples collected from seven local poultry farms in Ilishan, Ogun State, Nigeria. The strains were identified by partial sequencing of 16S rRNA genes. Antibiotic susceptibility of the isolates to vancomycin, erythromycin, tetracycline, gentamicin, amoxycillin/claulanate, and of loxacin were performed by disc diffusion method. Detection of tet, erm, and van genes and IS256 insertion element were done by polymerase chain reaction amplification. Results: Sixty enterococci spp. were identified comprising of Enterococcus faecalis 33 (55%), Enterococcus casseliflavus 21 (35%), and Enterococcus gallinarium 6 (10%). All the isolates were resistant to erythromycin (100%), followed by tetracycline (81.67%), amoxicillin/clavulanic acid (73.33%), ofloxacin (68.33%), vancomycin (65%), and gentamicin (20%). None of the enterococcal spp. harbored the van and erm genes while tet(M) was detected among 23% isolates and is distributed mostly among E. casseliflavus. IS256 elements were detected only in 33% of E. casseliflavus that were also positive for tet(M) gene. Conclusion: This study provides evidence that tetracycline resistance gene is present in the studied poultry farms in Ilishan, Ogun State, Nigeria and underscores the need for strict regulation on tetracycline usage in poultry farming in the studied location and

    The effect of highways and local activities on the quality of groundwater in Ogun State, Nigeria was investigated. This was done by collecting groundwater samples from three different districts in the state, located in Southwestern Nigeria. The water samples collected at 5 m from the highway and control samples collected at 3 km from the highway were analyzed for the following physicochemical parameters: pH, conductivity, chemical oxygen demand, alkalinity, total hardness, total solid, suspended solid, dissolved solid, chloride, sulfate, phosphate, nitrate, phenol, and the metals-lead, zinc, iron, aluminum, sodium, and potassium. The levels of chromium, copper, and cadmium in the samples were below the detectable limit. The levels of the parameters show that there are significant differences between those in the samples and the controls (F test) except for phosphate and phenol. Also, anthropogenic sources (local activities) elevate the levels of different specific parameters, which are related to these activities. Good correlation was observed between traffic density and lead levels as well as between conductivity and dissolved solids. Comparisons with the World Health Organization guidelines indicate that most of the water samples are not suitable for human consumption.

    Aim/Background: Plants and plants extracts are employed in cultures for religious purposes, as beauty therapies, in the detection and management/treatment of diseases. Materials and Methodology: In this study, an ethnobotanical studies of plants used in detecting pregnancy in Ijebu and Remo areas of Ogun State were carried out using semi-structured to obtain demographic data, local names of plants, the morphological parts used. Furthermore, a phytochemical analysis of two of the identified plants was performed. Topical and urine tests of plants in detecting pregnancy were designed to mimic procedures used in traditional medicine for detecting pregnancy. Results: Five plant species were identified belonging to the families Araceae, Asteraceae, Convolvulaceae, Nyctaginaceae, and Rubiaceae in the survey. The identified plants had the use value (UV) of 0.25 (Culcasia scandens), 0.17 (Ipomoea mauritiana), Boerhavia diffusa while Launea taraxacifolia and Chassalia kolly had the UV of 0.08, respectively. B. diffusa L, C. kolly (Schumach) Hepper tested positive for the presence of flavonoids, alkaloids, and tannins. The onset and duration of symptoms of both B. diffusa and C. kolly leaves at 2000 and 1000 mg were dose-dependent. The hexane, ethyl acetate, and ethanol extracts of B. diffusa and C. kolly exhibited pruritus and restlessness in the in vivo model while the urine of pregnant women caused black spots on the leaves of L. taraxacifolia (Willd) Amin Ex. C. Jeffrey. Conclusion: This study reports a rare knowledge of using plants in detecting pregnancy in the Remo and Ijebu areas of Ogun State, Nigeria. PMID:28163967

    Background The control of urinary schistosomiasis in Ogun State, Nigeria remains inert due to lack of reliable data on the geographical distribution of the disease and the population at risk. To help in developing a control programme, delineating areas of risk, geographical information system and remotely sensed environmental images were used to developed predictive risk maps of the probability of occurrence of the disease and quantify the risk for infection in Ogun State, Nigeria. Methods Infection data used were derived from carefully validated morbidity questionnaires among primary school children in 2001–2002, in which school children were asked among other questions if they have experienced "blood in urine" or urinary schistosomiasis. The infection data from 1,092 schools together with remotely sensed environmental data such as rainfall, vegetation, temperature, soil-types, altitude and land cover were analysis using binary logistic regression models to identify environmental features that influence the spatial distribution of the disease. The final regression equations were then used in Arc View 3.2a GIS software to generate predictive risk maps of the distribution of the disease and population at risk in the state. Results Logistic regression analysis shows that the only significant environmental variable in predicting the presence and absence of urinary schistosomiasis in any area of the State was Land Surface Temperature (LST) (B = 0.308, p = 0.013). While LST (B = -0.478, p = 0.035), rainfall (B = -0.006, p = 0.0005), ferric luvisols (B = 0.539, p = 0.274), dystric nitosols (B = 0.133, p = 0.769) and pellic vertisols (B = 1.386, p = 0.008) soils types were the final variables in the model for predicting the probability of an area having an infection prevalence equivalent to or more than 50%. The two predictive risk maps suggest that urinary schistosomiasis is widely distributed and occurring in all the Local Government Areas (LGAs) in State. The high

    Pre-eclampsia is a complication of pregnancy responsible for high rates of morbidity and mortality, particularly in sub-Saharan Africa. When undetected or poorly managed, it may progress to eclampsia which further worsens the prognosis. While most studies examining pre-eclampsia have used a bio-medical model, this study recognizes the role of the socio-cultural environment, in order to understand perceptions of pre-eclampsia within the community. The study was conducted in Ogun State, Nigeria in 2011-2012. Data were obtained through twenty-eight focus group discussions; seven with pregnant women (N = 80), eight with new mothers (N = 95), three with male decision-makers (N = 35), six with community leaders (N = 68), and three with traditional birth attendants (N = 36). Interviews were also conducted with the heads of the local traditional birth attendants (N = 4) and with community leaders (N = 5). Data were transcribed verbatim and analysed in NVivo 10 software. There was no terminology reportedly used for pre-eclampsia in the native language - Yoruba; however, hypertension has several terms independent of pregnancy status. Generally, 'gìrì âlábôyún' describes seizures specific to pregnancy. The cause of hypertension in pregnancy was thought to be due to depressive thoughts as a result of marital conflict and financial worries, while seizures in pregnancy were perceived to result from prolonged exposure to cold. There seemed to be no traditional treatment for hypertension. However for seizures the use of herbs, concoctions, incisions, and topical application of black soap were widespread. This study illustrates that knowledge of pre-eclampsia and eclampsia are limited amongst communities of Ogun State, Nigeria. Findings reveal that pre-eclampsia was perceived as a stress-induced condition, while eclampsia was perceived as a product of prolonged exposure to cold. Thus, heat-related local medicines and herbal concoctions were the

    Fish supplies 25% of the total protein source in developing countries. A techno-economic analysis was performed for developing a good business proposal for aquaculture loans to enhance aquaculture development in Nigeria. A case study of catfish Clarias gariepinus framing was conducted in Abeokuta North Local Government of Ogun State, Nigeria. The results show that the fixed cost is N18 338 per year, and the variable cost is N459 700 per year, accounting for the largest amount of the total; therefore, a profit of N43 289 per month can be made. Sensitivity analysis was performed to assess any risk(s) that associated with unfavorable changes in government policy with particular reference to monetary policy. Positive net present value shows that the investment in fish farm is economically feasible and the net investment ratio is 3.52. Also, the benefit-cost ratio is 2.17. The internal rate of return (IRR) is 21% showing that the enterprise is able to offset the interest being charged on the loan. It is therefore worthwhile to invest into fish farm business in the study area. The study suggests that to better sustain the local aquaculture business, the government should create a good conducive environment to foster development of the fish farming. Government intervention is urgently needed to solve problems such as in traditional land tenure, grant credit facilities and subsidies, to enhance the aquacultural development in the country.

    Introduction In preparation for Mass Drug Administration by National Lymphatic Filariasis Elimination Programme, a baseline epidemiological investigation on lymphatic filariasis (LF) was conducted in two sentinel sites of Ogun State, Nigeria. The study was carried out in Ado-Odo Ota and Abeokuta South Local Government Areas (LGAs) to determine LF prevalence, microfilarial density and the abundance of Wucheraria bancrofti in the mosquito vectors. Methods Microscopic examination of thick blood smears of 299 and 288 participants from Ado-Odo Ota and Abeokuta South LGAs was conducted. Visual observations of clinical manifestations of chronic infection and questionnaire administration were also conducted. Indoor resting mosquitoes were collected using the pyrethrum spray technique and CDC light traps and mosquitoes were dissected for filarial larvae. Results Microfilaria prevalences were 4.0% and 2.4% in Ado-odo Ota and Abeokuta South LGAs. The microflarial density (mfd) was 30.6mf/ml and 23.9 mf/ml in the same areas. No clinical manifestations of the infection were found at both sites. Knowledge of LF by inhabitants was very low in the two areas. Anopheles gambiae s.l and Culex species mosquitoes were collected but none was found positive for stage L3 infective larvae. Conclusion Mass awareness campaigns on the goal of mass drug administration, cause of LF, mode of transmission, the relationship between infection and clinical signs/symptoms is advocated so as to increase acceptance and support of the control programme by the community.

    This study assessed the geohelminth and nutritional status of preschoolers in a periurban community of Ogun state. Fresh stool specimens were collected for laboratory analysis, processed using ether concentration method, and examined under the microscope for geohelminth ova. Demographic characteristics and daily nutrient intake of children were subjectively assessed during an interview session with parents, following anthropometric data collection. Data obtained were analysed using a statistical software for Windows. Nutritional indicators such as underweight, stunting, and wasting were computed from anthropometric data. Results showed an overall prevalence of 39.2% and 12.4% for Ascariasis and Hookworm infection, respectively, with no significant difference (P > 0.05) between the sexes. Prevalence of nutritional indicators was 52.6%, 35.1%, 34.0%, and 9.3% for underweight, stunting, wasting, and thinness conditions, respectively. A good proportion of the malnourished preschoolers were free of Ascaris infection but infected with Hookworm parasite. The adverse effect of geohelminth infection cannot still be ignored in impaired growth, reduced survival, poor development, and cognitive performance of preschoolers. Therefore promotion of adequate health education program on measures of preventing geohelminth infections is needed.

    Job satisfaction implies doing a job one enjoys, doing it well, and being suitably rewarded for one' efforts. Several factors affect job satisfaction. To compare factors influencing job satisfaction amongst rural and urban primary health care workers in southwestern Nigeria. A cross sectional comparative study recruited qualified health workers selected by multi stage sampling technique from rural and urban health facilities in four local government areas (LGAs) of Ogun State in Southwestern Nigeria. Data were collected and analysed using Epi info V 3.5.1 RESULTS: The response rates were 88(88%) and 91(91%) respectively in the rural and urban areas. While urban workers derived satisfaction from availability of career development opportunities, materials and equipment, in their current job, rural workers derived satisfaction from community recognition of their work and improved staff relationship. Major de-motivating factors common to both groups were lack of supportive supervision, client-provider relationship and lack of in-service training. However more rural 74(84.1%) than urban 62(68.1%) health workers would prefer to continue working in their present health facilities (p=0.04). There was a statistically significant difference between the two groups in job satisfaction with respect to tools availability and career development opportunities (p<0.05). There is dissimilarity in factors influencing job satisfaction between rural and urban healthcare workers. There is need for human resource policy to be responsive to the diverse needs of health workers particularly at the primary level.

    A good quality drinking water is essential for human survival. However, a large percentage of the populations in most developing countries (Nigeria inclusive) do not have access to potable water. This study was therefore conducted to assess the extent of risk arising from consumption of toxic elements in groundwater samples collected from Lagos and Ogun States, Southwest, Nigeria. Twelve toxic elements concentrations (As, Mn, Cd, Cr, Pb, Ni, Al, Ti, V, Hg, Li, and Sn) were determined from 170 groundwater samples using inductively coupled plasma-mass spectrometry, and the physicochemical parameters were determined using standard methods. The pH results revealed that most of the water samples were slightly acidic. Of the twelve toxic elements, only Mn, Cd, Pb, Ni, and Al have concentrations higher than the WHO recommended limit in drinking water. The average dose of Mn and Al consumed daily from groundwater by an adult in Lagos state is 3.4 and 23.2 (μg/kg body weight), respectively. Similarly, an adult in Ogun State consumed an average daily dose of 6.09 and 25 (μg/kg body weight) Mn and Al, respectively. A greater threat was posed to children and infants. The order for risk of cancer in groundwater from Lagos State was Pb > Cr > As > Cd while the order in Ogun State groundwater was Cr > Cd > As > Pb. The relative high concentrations of Mn, Al, and Pb obtained in this study can be attributed to industrial and anthropogenic activities in the study area. Treatment of groundwater before consumption is recommended to avoid possible adverse cumulative effect. Improved waste disposal methods and regular monitoring of toxic elements in groundwater of the study area should be adopted to safeguard human health.

    Filth-feeding and breeding, non-biting synanthropic flies have been incriminated in the dissemination of human enteropathogens in the environment. This study determined the species of non-biting synanthropic flies associated with four filthy sites in Ilishan, Ogun State, southwest Nigeria, and assessed their potentials for mechanical transmission of human intestinal parasites. 7190 flies identified as Musca domestica (33.94%), Chrysomya megacephala (26.01%), Musca sorbens (23.23%), Lucilia cuprina (8.76%), Calliphora vicina (4.59%), Sarcophaga sp. (2.78%) and Fannia scalaris (0.70%) were examined for human intestinal parasites by the formol-ether concentration and modified Ziehl-Neelsen techniques. Eggs of the following parasites: Ascaris lumbricoides (34.08%), Trichuris trichiura (25.87%), hookworms (20.45%), Taenia sp. (2.36%), Hymenolepis nana (1.11%), Enterobius vermicularis (0.56%), Strongyloides stercoralis (larvae; 3.89%) and cysts of Entamoeba histolytica/dispar (27.26%), Entamoeba coli (22.67%), Giardia lamblia (3.34%) and Cryptosporidium sp. (1.81%) were isolated from the body surfaces and or gut contents of 75.24% of 719 pooled fly batches. The helminths A. lumbricoides and T. trichiura and the protozoans, E. histolytica/dispar and E. coli were the dominant parasites detected, both on body surfaces and in the gut contents of flies. C. megacephala was the highest carrier of parasites (diversity and number). More parasites were isolated from the gut than from body surfaces (P < 0.05). Flies from soiled ground often carried more parasites than those from abattoir, garbage or open-air market. Synanthropic fly species identified in this study can be of potential epidemiological importance as mechanical transmitters of human intestinal parasites acquired naturally from filth and carried on their body surfaces and or in the gut, because of their vagility and feeding mechanisms.

    In Nigeria, women too often suffer the consequences of serious obstetric complications that may lead to death. Delay in seeking care (phase I delay) is a recognized contributor to adverse pregnancy outcomes. This qualitative study aimed to describe the health care seeking practices in pregnancy, as well as the socio-cultural factors that influence these actions. The study was conducted in Ogun State, in south-western Nigeria. Data were collected through focus group discussions with pregnant women, recently pregnant mothers, male decision-makers, opinion leaders, traditional birth attendants, health workers, and health administrators. A thematic analysis approach was used with QSR NVivo version 10. Findings show that women utilized multiple care givers during pregnancy, with a preference for traditional providers. There was a strong sense of trust in traditional medicine, particularly that provided by traditional birth attendants who are long-term residents in the community. The patriarchal c influenced health-seeking behaviour in pregnancy. Economic factors contributed to the delay in access to appropriate services. There was a consistent concern regarding the cost barrier in accessing health services. The challenges of accessing services were well recognised and these were greater when referral was to a higher level of care which in most cases attracted unaffordable costs. While the high cost of care is a deterrent to health seeking behaviour, the cost of death of a woman or a child to the family and community is immeasurable. The use of innovative mechanisms for health care financing may be beneficial for women in these communities to reduce the barrier of high cost services. To reduce maternal deaths all stakeholders must be engaged in the process including policy makers, opinion leaders, health care consumers and providers. Underlying socio-cultural factors, such as structure of patriarchy, must also be addressed to sustainably improve maternal health. NCT

    Background A study of the helminth infection status of primary-school children and the hygiene condition of schools in Ikenne Local Government Area of Ogun State, Nigeria was undertaken between November 2004 and February 2005 to help guide the development of a school-based health programme. Methods and Findings Three primary schools were randomly selected: two government-owned schools (one urban and the other rural) and one urban private school. No rural private schools existed to survey. A total of 257 schoolchildren aged 4–15 y, of whom 146 (56.8%) were boys and 111 (43.2%) were girls, took part in the survey. A child survey form, which included columns for name, age, sex, and class level, was used in concert with examination of stool samples for eggs of intestinal helminths. A school survey form was used to assess the conditions of water supply, condition of latrines, presence of soap for handwashing, and presence of garbage around the school compound. The demographic data showed that the number of schoolchildren gradually decreased as their ages increased in all three schools. The sex ratio was proportional in the urban school until primary level 3, after which the number of female pupils gradually decreased, whereas in the private school, sexes were proportionally distributed even in higher classes. The prevalence of helminth infection was 54.9% of schoolchildren in the urban government school, 63.5% in the rural government school, and 28.4% in the urban private school. Ascaris lumbricoides was the most prevalent species, followed by Trichuris trichiura, Taenia species, and hookworm in the three schools. Prevalence of infection in the government-owned schools was significantly higher than in the private school (χ2 = 18.85, df = 2, p<0.0005). A survey of hygiene conditions in the three schools indicated that in the two government schools tapwater was unavailable, sanitation of latrines was poor, handwashing soap was unavailable, and garbage was

    Objective: The study assessed the risk of developing type 2 diabetes Mellitus in Ogun State, Nigeria. Materials and Methods: Finnish Medical Association diabetes risk score was administered across 25 communities facilitated by non-communicable disease clinics established under a World Diabetes Foundation project. Subjects in the high risk group had blood glucose estimated. Results: 58,567 respondents included 34,990 (59.6%) females and 23,667 (40.3%) males. Majority (61.2%) were between 25 years and 54 years. Considering waist circumference, 34,990 (38.1%) females and 23,667 (5.3%) males had values above 88 cm and 102 cm respectively. Overall, 11,266 (19.2%) were obese and 28.9% overweight using body mass index (BMI). More females had elevated BMI than males. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) of all subjects were 129.54 mm Hg ± 23.5 mm Hg and 76.21 mm Hg ± 15.5 mm Hg respectively. Prevalence of hypertension (Joint National Committee VII classification) was 27.7%. More subjects had normal DBP than SBP (68.2% vs. 42.5% P < 0.05). Mean fasting blood glucose (FBG) of all subjects was 5.5 mmol/L ± 0.67 mmol/L. Using a casual blood glucose >11.1 mmol/L and/or FBG >7 mmol/L, the total yield of subjects adjudged as having diabetes was 2,956 (5.05%). Mean total risk score was 5.60 ± 3.90; this was significantly higher in females (6.34 ± 4.16 vs. 4.24 ± 3.71, P < 0.05). A total of 2,956 (5.05%) had high risk of developing DM within 10 years. Conclusion: The risk of developing DM is high in the community studied with females having a higher risk score. There is urgent need to implement diabetes prevention strategies. PMID:23961481

    Malaria case management remains a vital component of malaria control strategies. Despite the introduction of national malaria treatment guidelines and scale-up of malaria control interventions in Nigeria, anecdotal evidence shows some deviations from the guidelines in malaria case management. This study assessed factors influencing adherence to malaria diagnosis and treatment guidelines among healthcare workers in public and private sectors in Ogun State, Nigeria. A comparative cross-sectional study was carried out among 432 (216 public and 216 private) healthcare workers selected from nine Local Government Areas using a multistage sampling technique. A pre-tested interviewer administered questionnaire was used to collect information on availability and use of malaria Rapid Diagnostic Test (mRDT) and artemisinin combination therapy (ACT), for management of uncomplicated malaria. Adherence was defined as when choice of antimalarials for parasitological confirmed malaria cases was restricted to recommended antimalarial medicines. Association between adherence and independent variables were tested using Chi-square at 5 % level of significance. Malaria RDT was available in 81.9 % of the public health facilities and 19.4 % of the private health facilities (p = 0.001). Its use was higher among public healthcare workers (85.2 %) compared to 32.9 % in private facilities (p = 0.000). Presumptive diagnosis of malaria was higher among private healthcare workers (94.9 %) compared to 22.7 % public facilities (p = <0.0001). The main reason for non-usage of mRDT among private healthcare workers was its perceived unreliability of mRDT (40.9 %). Monotherapy including artesunate (58.3 % vs 12.5 %), amodiaquine (38.9 % vs 8.3 %) and chloroquine (26.4 % vs 4.2 %) were significantly more available in private than public health facilities, respectively. Adherence to guidelines was significantly higher among public healthcare workers (60.6 %) compared to those

    A survey was undertaken to determine the aflatoxin M(1) contamination of milk and some locally produced dairy products in Abeokuta and Odeda local governments of Ogun State, Nigeria. Samples of human and cow milk, yoghurt, "wara", ice cream and "nono" were collected randomly within the local governments and analysed for aflatoxin M(1) using the two-dimensional TLC. Aflatoxin M(1) contamination in the range of 2.04-4.00 microg l(-1) was noticed only in milk and ice cream. In particular, samples of human milk, cow milk and ice cream recorded high scores of 4.0 microg l(-1), 2.04 microg l(-1) and 2.23 microg l(-1), respectively in Abeokuta local governments and a score of 4.0 microg l(-1) for cow milk in Odeda local government. This indicates a high level contamination in the local governments since the weighted mean concentration of aflatoxin M1 in milk for African diet is 0.002 microg l(-1). Therefore the concentration of AFB1 in feeds which is transformed to AFM1 in milk should be reduced by good manufacturing and good storage practices. Furthermore, there is need for stringent quality control during processing and distribution of these products.

    Activity concentrations of (40)K, (226)Ra, (228)Ac and (235)U were measured in 11 dug and 9 drilled well water samples from 3 large cities in Ogun state, Southwestern Nigeria, consumed by the population living in the cities. The measurement was done using co-axial type high-purity germanium (HPGe) detector (Canberra Industries Inc.). The measured activity concentrations in the water samples ranged from 1.74 +/- 1.83 to 4.69 +/- 0.17 Bq l(-1); 2.89 +/- 0.62 to 7.79 +/- 7.22 Bq l(-1); 0.35 +/- 0.07 to 1.17 +/- 0.40 Bq l(-1) and 0.18 +/- 0.05 to 4.77 +/- 0.34 Bq l(-1) for (40)K, (226)Ra, (228)Ac and (235)U, respectively. Total annual effective dose rates from the ingestion of these radionuclides in the untreated wells were estimated using measured activity concentrations in the radionuclides and their ingested dose conversion factors. Estimated annual effective dose rates ranged from 0.04 to 6.82; 0.01 to 1.36 and 0.01 to 1.49 mSv y(-1) for age groups <1, 2-7 and > or =17 y, respectively. Committed dose for age group > or =17 y ranged from 8.8 x 10(-4) to 8.9 x 10(-2) Sv. The calculated annual effective dose values due to the ingestion of (226)Ra in the Awujale, Ake, Saboab, Alagbon, Alapora and Totoro samples exceeded International Commission on Radiological Protection limit of 1.0 mSv y(-1) for individual public exposure. These wells are recommended for treatment that would remove radium from their waters.

    HIV counseling and testing (CT) is slowly being introduced as one of several key components of the comprehensive package of HIV/AIDS prevention and care in Nigeria, particularly in the prevention of mother-to-child transmission of HIV (PMTCT). A cross-sectional survey of 804 women attending antenatal clinics (ANC) in Ogun State, Nigeria was done using questionnaires to assess their willingness to seek and undergo CT and know the determinants. Focus group discussions were also held in the general community: 84.3% of respondents believed in AIDS reality, while 24.3% thought they were at risk of HIV infection. Only 27% knew about MTCT, while 69.7% of 723 who had heard of HIV/AIDS did not know about CT. Only 71 (8.8%) had thought about CT and 33 (4.5%) mentioned HIV testing as one of antenatal tests. After health education on CT, 89% of the women expressed willingness to be tested. Their willingness for CT was positively associated with education (p < 0.05), ranging from 77% (no education) to 93% (post-secondary). More of those with self-perceived risk expressed willingness to test for HIV (p < 0.05). Those willing to be tested had a higher knowledge score on how HIV spreads than those not willing. Multiple regressions identified four key factors that were associated with willingness for CT: increasing educational level; not fearing a blood test; perception that the clinic offered privacy; and perceptions of higher levels of social support from relatives and peers. Those unwilling or undecided about CT expressed strong fear of social stigma/rejection if tested positive. The results provided insights for planning promotional programs and showed that not only are IEC efforts needed to boost knowledge about HIV/AIDS, but that change in clinic setting and community are imperative in creating supportive environment to encourage uptake of CT services.

    This is a three-year retrospective study of the pattern and outcome of acute medical admissions at the Ogun State University Teaching Hospital, Sagamu. Our findings showed that there were 1,938 admissions over the study period of which 1,044 (54%) were females and 894 (46%) were males. The ages of the patients ranged between 12 to 86 years with a mean of 49 +/- 1.7 years. The age range was 14 to 80 years for males with a mean of 47 +/- 6.1 years and 12 to 86 years for females with a mean of 49 +/- 4.5 years. The length of stay was between 5 to 25 days with a mean of 15 +/- 0.5 days. There were 16 patients per bed per year with a turn around of 8 days and bed occupancy of 65% 194 (10%) patients discharged themselves against medical advice and there were 488 (25%) deaths. The interval between admission and death ranged between 4 to 7 days with a mean of 5.5 +/- 0.07 days. Indications for admissions were infectious diseases (38%), neurological disorders (19.6%) gastro-intestinal disorders (11%), genito-urinary tract disorders (10.2%) endocrine disorder (10%), cardiovascular disorders (9.9%), respiratory disorders (6.4%) and haematological disorders (4.9%). Tuberculosis accounted for 10% of total medical admissions and was the commonest disease entity responsible for medical admissions. Acquired immuno deficiency syndrome (AIDS) constituted 1.8% of medical admissions. Mortality was highest for infections accounting for 32% of deaths while malaria accounted for the lowest. The reasons for the relative frequency and mortality are adduced. The study recommends improvement of preventive strategies towards communicable diseases in the community and encourages better admission policy, provision of appropriate facilities and manpower to improve the hospital services.

    Most febrile patients are often misdiagnosed with malaria due to similar symptoms, such as fever shared by malaria and certain arboviral infections. This study surveyed the incidence of malaria, chikungunya and dengue infections among a number of suspected febrile patients visiting Simawa Health Centre, Ogun State, Nigeria. Venous blood samples were obtained from 60 febrile patients (age 3-70 years) visiting the centre between April and May 2014. The rapid diagnostic test (RDT) was used to detect the presence of chikungunya (CHK) antibodies (IgM), dengue (DEN) virus and antibodies (NS1, IgM and IgG) and malaria parasites (Plasmodium falciparum and Plasmodium vivax). Malarial confirmatory tests were by microscopy and nested polymerase chain reaction (PCR) using the polymorphic region of Glutamate-Rich Protein (GLURP) gene. The complexity of P. falciparum infection in the community also determined by the use of nested PCR. These three mosquito-borne infections were observed in 63% (38) of the patients. The prevalence of CHK, DEN and malarial infections singularly were 11%, 0% and 63%, respectively, whereas malaria with either CHK or DEN infections were 24% (9) and 3% (1), respectively. No subjects were positive for CHK and DEN co-infection. Malarial microscopic confirmation was in 94% (32) of the malaria RDT-positive samples, 50% (17) were successfully analysed by nested PCR and the mean multiplicity of infection was 1.6 (1-3 clones). One patient sample harboured both P. falciparum and P. vivax. The study reports the presence of some arboviral infections having similar symptoms with malaria at Simawa, Ogun State. The proper diagnosis of infectious diseases is important for controlling them.

    Africa is the most affected continent with 200,000 new born affected by sickle cell anemia annually with of 5% of under five deaths. Nigeria has the largest sickle cell gene pool in the world with about 2% of all babies born to Nigerian parents. This study therefore sets out to assess the prevention practices influencing the frequency of occurrence of vaso-occlusive crisis among patients in Ogun State. This study is a descriptive cross-sectional study conducted in Abeokuta South Local Government Area Ogun State. A consecutive non randomized sampling of all the sickle cell patients that attend the selected facilities was recruited into the study. Data were collected with the use of questionnaires which were interviewer administered. A total of 415 patients were recruited into the study. Statistical analyses were conducted using SPSS for Windows version 20.0. Two- third [64.8%] of study participants have crisis twice or more in a month. The frequency of crisis was statistically significantly associated with the age of the child [p = 0.006], use of anti-malaria prophylaxis [p = 0.006], analgesics [p = 0.0001], taking of plenty fluid [p = 0.001] and soothing herbs [p = 0.0001]. Lifestyle factors such as giving balance diet [p = 0.217], restriction from strenuous activities [p = 0.08], and attending Clinic appointments regularly [p = 0.126] were not statistically associated with reduction in the frequency of crisis. Logistic regression analysis shows that predictors of frequent crisis were individuals who were using prophylaxis antimalarial drugs [OR = 0.12, CI = 0.05-0.33] and analgesics [OR = 0.15, C.I = 0.06-0.34]. The study reveals that majority of the participants have high frequency of crisis in a month. Drug prophylaxis rather than lifestyle factors may be more important in the prevention of vaso-occlusive crisis among sickle cell patients.

    Heavy metals are known to have a negative impact on human health especially children through oral ingestion. Total metal concentrations were determined in indoor dust from 19 locations consisting of classrooms, living rooms and offices in Ogun State, Nigeria. Digestion and instrumentation reproducibility were validated using certified reference materials (BCR 723 (Road Dust), NIST 2711a (Montana Soil) and NIST SRM 1640e (Trace element in water)). The measured and certified values showed good agreement. Potential threat levels using geo-accumulation (Igeo) and human health risk for both children and adult were assessed. The mean Igeo levels for the classified and probable carcinogens is in the order Cd (4.84) > Cr (3.28) > Pb (2.61) > Ni (2.48) > As (1.64) while other elements are in the order Zn (5.41) > Ba (4.86) > Sr (4.38) > Zn (4.27) > V (3.24) > Cu (3.14) > Hg (2.61) ≈ TI (2.61). For human health risk, ingestion was the main route of exposure followed by dermal uptake and inhalation. Hazard index values for all studied metals were lower than the safe level of 1 while Hg vapor exhibited the highest risk value (0.13) in the case of children. The carcinogenic risk for As, Cd, Co, Cr, Ni and Pb were all within the acceptable level (10-4-10-6), but there was potential carcinogenic risk posed by Cr for both adults and children.

A health education interventional study of this nature is essential in primary control of an endemic communicable disease such as malaria. This study was therefore designed to determine the effect of health education on the home management of Malaria among the caregivers of children under 5 years old in Ogun State, Nigeria. Methods The study design was a quasi-experimental study carried out in Ijebu North Local Government Area of Ogun State. A multistage random sampling technique was used in choosing the required samples for this study and a semi-structured questionnaire was used to collect relevant information. The intervention consisted of a structured educational program based on a course content adapted from the national malaria control program. A total of 400 respondents were recruited into the study, with 200 each in both the experimental and control groups, and were followed up for a period of 3 months when the knowledge and uptake of insecticide treated net was reassessed. Results There was no statistically significant differences observed between the experimental and control groups in terms of sociodemographic characteristics such as age (P = 0.99), marital status (P = 0.48), religion (P = 0.1), and income (P = 0.51). The majority in both the experimental (75.0%) and control (71.5%) groups use arthemisinin-based combination therapy as first line home treatment drugs pre intervention. Post health education intervention, the degree of change in the knowledge of referral signs and symptoms in the experimental group was 52.8% (P < 0.0001) while it was 0.2% in the control group (P = 0.93). Tepid sponging improved by 45.0%, paracetamol use by 55.3%, and the use of herbs and other drugs were not significantly influenced in the experimental (P = 0.65 and 0.99) and control group (P = 0.89 and 0.88), respectively

    Airway inflammation and related respiratory complaints are common symptoms among waste management workers (WMWs). This study investigated the relationship between exposure to municipal solid waste (MSW) and the levels of inflammatory markers and oxidative stress among WMW of Ogun State, South West Nigeria. A total of 280 subjects consisting of 180 WMW and 100 controls were recruited. Ten millilitres of blood were collected from antecubital vein of the subjects for analysis. Results reveal that exposure to MSW is associated with systemic inflammation and oxidative stress. Significant (p < 0.001) elevation of ceruloplasmin (Cp) and C-reactive protein was associated with marked decreases in superoxide dismutase (p < 0.01), catalase (p < 0.001), and glutathione (p < 0.05) and significant (p < 0.001) increases in malondialdehyde (MDA) and uric acid when compared with control. Haematological disorders include significant (p < 0.05) decreases in haemoglobin, packed cell volume, and mean corpuscular volume and significant (p < 0.01) increase in total leucocyte count. Apart from decreased albumin (p < 0.05) and elevated aspartate aminotransferase (p < 0.05) activity observed in WMW, other markers of hepatic (alanine aminotransferase, alkaline phosphatase, total cholesterol and triglycerides) and renal (urea and creatinine) functions did not change significantly (p > 0.05) when compared with the control. A positive correlation between leucocytes (r = 0.195, p < 0.01), Cp (r = 0.210, p < 0.01) and job duration and between Cp and MDA (r = 0.200, p < 0.01) and Cp and leucocytes (r = 0.260, p < 0.001) were observed in WMW. Overall, exposure to MSW predisposes to systemic inflammation and oxidative stress and Cp may be a useful biomarker for monitoring health status of Nigerian WMWs.

    Pre-eclampsia is a leading cause of maternal and fetal morbidity and mortality worldwide. Early detection and treatment have been instrumental in reducing case fatality in high-income countries. To achieve this in a low-income country, like Nigeria, community health workers who man primary health centres must have adequate knowledge and skills to identify and provide emergency care for women with pre-eclampsia. This study aimed to determine community health workers' knowledge and practice in the identification and treatment of pre-eclampsia, as they are essential providers of maternal care services in Nigeria. This study was part of a multi-country evaluation of community treatment of pre-eclampsia. Qualitative data were obtained from four Local Government Areas of Ogun State, in south western Nigeria by focus group discussions (N = 15) and in-depth interviews (N = 19). Participants included a variety of community-based health care providers - traditional birth attendants, community health extension workers, nurses and midwives, chief nursing officers, medical officers - and health administrators. Data were transcribed and validated with field notes and analysed with NVivo 10.0. Community-based health care providers proved to be aware that pre-eclampsia was due to the development of hypertension and proteinuria in pregnant women. They had a good understanding of the features of the condition and were capable of identifying women at risk, initiating care, and referring women with this condition. However, some were not comfortable managing the condition because of the limitation in their 'Standing Order'; these guidelines do not explicitly authorize community health extension workers to treat pre-eclampsia in the community. Community-based health care providers were capable of identifying and initiating appropriate care for women with pre-eclampsia. These competencies combined with training and equipment availability could improve maternal health in the rural

This situation increases the risk of death for both mother and child and has severe maternal and neonatal health complications. The purpose of this study was to explore pregnant women’s perceptions and utilization of traditional birth attendant (TBA) services in a rural Local Government Area (LGA) in Ogun State, southwest Nigeria. Methods A quantitative design was used to obtain information using a structured questionnaire from 250 pregnant women attending four randomly selected primary health care clinics in the LGA. Data were analyzed using Epi Info (v 3.5.1) statistical software. Results Almost half (48.8%) of the respondents were in the age group 26–35 years, with a mean age of 29.4 ± 7.33 years. About two-thirds (65.6%) of the respondents had been pregnant 2–4 times before. TBA functions, as identified by respondents, were: “taking normal delivery” (56.7%), “providing antenatal services” (16.5%), “performing caesarean section” (13.0%), “providing family planning services” (8.2%), and “performing gynaecological surgeries” (5.6%). About 6/10 (61.0%) respondents believed that TBAs have adequate knowledge and skills to care for them, however, approximately 7/10 (69.7%) respondents acknowledged that complications could arise from TBA care. Services obtained from TBAs were: routine antenatal care (81.1%), normal delivery (36.1%), “special maternal bath to ward off evil spirits” (1.9%), “concoctions for mothers to drink to make baby strong” (15.1%), and family planning services (1.9%). Reasons for using TBA services were: “TBA services are cheaper” (50.9%), “TBA services are more culturally acceptable in my environment” (34.0%), “TBA services are closer to my house than hospital services” (13.2%), “TBAs provide more compassionate care than orthodox health workers” (43.4%), and “TBA service is the only

    The dearth of health personnel in low income countries has attracted global attention. Ways as to how health care services can be delivered in a more efficient and effective way using available health personnel are being explored. Task-sharing expands the responsibilities of low-cadre health workers and allows them to share these responsibilities with highly qualified health care providers in an effort to best utilize available human resources. This is appropriate in a country like Nigeria where there is a shortage of qualified health professionals and a huge burden of maternal mortality resulting from obstetric complications like pre-eclampsia. This study examines the prospect for task-sharing among Community Health Extension Workers (CHEW) for the detection of early signs of pre-eclampsia, in Ogun State, Nigeria. This study is part of a larger community-based trial evaluating the acceptability of community treatment for severe pre-eclampsia in Ogun State, Nigeria. Data was collected between 2011 and 2012 using focus group discussions; seven with CHEWs (n = 71), three with male decision-makers (n = 35), six with community leaders (n = 68), and one with member of the Society of Obstetricians and Gynaecologists of Nigeria (n = 9). In addition, interviews were conducted with the heads of the local government administration (n = 4), directors of planning (n = 4), medical officers (n = 4), and Chief Nursing Officers (n = 4). Qualitative data were analysed using NVivo version 10.0 3 computer software. The non-availability of health personnel is a major challenge, and has resulted in a high proportion of facility-based care performed by CHEWs. As a result, CHEWs often take on roles that are designated for senior health workers. This role expansion has exposed CHEWs to the basics of obstetric care, and has resulted in informal task-sharing among the health workers. The knowledge and ability of CHEWs to perform basic clinical assessments

    OAK-B135 This paper is submitted in fulfillment of DOE Grant No. DE-FG03-015F22369 on the experience of western states/provinces with demand response (DR) in the electricity sector. Demand-side resources are often overlooked as a viable option for meeting load growth and addressing the challenges posed by the region's aging transmission system. Western states should work together with utilities and grid operators to facilitate the further deployment of DR programs which can provide benefits in the form of decreased grid congestion, improved system reliability, market efficiency, price stabilization, hedging against volatile fuel prices and reduced environmental impacts of energy production. This report describes the various types of DR programs; provides a survey of DR programs currently in place in the West; considers the benefits, drawbacks and barriers to DR; and presents lessons learned and recommendations for states/provinces.

    The quality of Ogun river in South-West, Nigeria was studied by a field survey for a period of 1 year (covering dry season and rainy season). Water samples were collected from thirteen sites and analysed for physico-chemical and bacteriological parameters as well as heavy metals using standard methods. Generally, the values obtained for turbidity, phosphate, oil and grease, iron and faecal coliform from all the sites in both seasons were above the maximum acceptable limit set by the World Health Organization (WHO) for drinking water. Also, the manganese content from all the sites in the dry season, lead concentrations from three sites in the dry season and cadmium concentrations from some sites in both seasons were above the WHO limit. The values obtained for total dissolved solids, dissolved oxygen and chloride at site M in the dry season and nitrate at site J in the rainy season were also above the WHO limit. Pollution of Ogun river water along its course is evidenced by the high concentrations of pollution indicators, nutrients and trace metals above the acceptable limit. This poses a health risk to several rural communities who rely on the river primarily as their source of domestic water. The study showed a need for continuous pollution monitoring programme of surface waters in Nigeria.

    Levels of Zn, Cu, Cd, As, and Pb in the kidney, Liver, Gills and Heart of African cat fish (Clarias gariepinus) from the Ogun River in Ogun State located close to six major industries in the South Western part of Nigeria, were determined using Bulk Scientific Atomic Absorption Spectrophotometer. Fishes were also collected from Government owned fish farm in Agodi, Ibadan which was considered a reference site. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), glutathione (GSH) concentration and malondialdehyde (MDA) formation were also determined. The trend of accumulation of the metals in the organs is as follows: Heart - Zn > Cu > Pb > As > Cd; Gills - Zn > Cu > Pb > Cd > As; Kidney - Zn > Cu > Pb > As > Cd; Liver -Zn > Cu > Pb > As > Cd. The order of concentration of the metals in the organs is as follows: Arsenite - Kidney > Liver > Gills > Heart; Zinc - Gills > Liver > Kidney > Heart; Lead- Liver > Kidney > Gills > Heart; Copper- Kidney > Liver > Gills > Heart; Cadmium > Liver > Gills > Kidney > Heart. The levels of heavy metals ranged between 0.25–8.96 ppm in the heart, 0.69– 19.05 ppm in the kidneys, 2.10–19.75 ppm in the liver and 1.95–20.35 ppm in the gills. SOD activity increased by 61% in the liver, 50% in the kidney and in the heart by 28 % while a significant decrease (44%) was observed in the gill of Clarias gariepinus from Ogun river compared to that Agodi fish farm (P<0.001). On the contrary there was 46%, 41%, 50% and 19% decrease in CAT activity in the liver, kidney, gills and heart respectively. The levels of GST activities in the liver, kidney and heart of Clarias gariepinus from Ogun river increased by 62%, 72% and 37% respectively (P<0.001) whereas there was a significant decrease (41%) in the gills (P<0.05) compared to that from the Agodi fish farm. GSH concentration increased by 81%, 83% and 53% in the liver, kidney and heart respectively but decreased by 44% in the gills. MDA levels of

    This article describes three cases of ;ogun oru' (nocturnal warefare), a condition reported in southwest Nigeria involving an acute night-time disturbance that is culturally attributed to demonic infiltration of the body and psyche during dreaming. Ogun oru is characterized by its occurrence, a female preponderance, the perception of an underlying feud between the sufferer's earthly spouse and a ;spiritual' spouse, and the event of bewitchment through eating while dreaming. The condition is believed to be treatable through Christian prayers or elaborate traditional rituals designed to exorcise the imbibed demonic elements. Ogun oru may be a label applied to medical problems. The differential diagnosis includes mainly parasomnias, for example, sleep terror, sleepwalking and sleep paralysis and, to a lesser extent, nocturnal or sleep epilepsy.

    Epidemiological studies were carried out to assess the prevalence and community microfilarial load (CMFL) of onchocerciasis after repeated annual treatment with ivermectin along Ogun river System, southwest Nigeria. Skin snips were taken from consented participants in 11 selected communities along the River system. The microfilarial load of the community was estimated. The prevalence and CMFL varied significantly in the communities (p <0.05). The prevalence of onchocerciasis ranged from 19.1 to 45.6%, while the CMFL ranged from 0.11 to 1.03 microfilariae per skin snip. The CMFL recorded was <5 microfilariae per skin snip, i.e. recognized by WHO as threshold value in certifying the communities to be free of onchocerciasis as public health problem, thus, signifying the possibility of onchocerciasis elimination in the study area. Efforts should therefore be intensified to achieve improved ivermectin coverage and compliance in annual ivermectin treatment in order to completely eliminate onchocerciasis as a public health problem in the studied communities.

    Merowe province in rural northern Sudan has been divided into three local government council areas: Merowe, Karima, and Ed Debba. A government program was instituted to increase the welfare of residents and food production. A baseline survey of 490 respondents was conducted in order to ascertain how illiterate women viewed development in the area and to provide useful information for program design and implementation. Women from 24 villages were administered questionnaires, observed in their daily activities, and engaged in discussion in a local meeting place. Discussions were also held with members of the local Popular Committee. Demographic information was very sketchy about age, and 48% had no formal education in writing and reading. General reading and writing skills of the remainder were very poor. There were 500 female children and 502 male children, and the sex ratio varied among the 3 council areas. 52% were married and 14% were divorced or widowed and living with relatives. The average monthly income was from Ls. 700 to Ls. 3000 based on reports from only 59.3% of respondents. Most of the women had skills in food processing and 25.7% were skilled in handicrafts. Water was obtained primarily from local wells and not decontaminated before use. Pit latrines were the standard. One bathing facility was available in the compound for the entire council area. Health units were either in each village or within 20-30 minutes walk. Child mortality was 4.3% in Merowe province. 77 children 0-5 years old died out of a total of 1002 live births. Life expectancy was 41-50 years for women and 61-70 years for men. Cleanliness and healthful eating were observed. 58% owned no land; plots were under 5 feddans and usually half a feddan. 92.1% had no bank account and 90% had no experience with loans. 70.2% were indifferent about involvement in an income generation program. 26% were interested in part-time participation. Only 3.9% desired full-time participation. 8.6% said they

  10. Seismic hazards in the Basin and Range province, United States

    Pancha, Aasha

    Deformation rates determined for the Basin and Range province using geodetic data agree within uncertainties with scalar moment rate estimates from a 146-year earthquake catalog. This agreement suggests that the rate of historic earthquakes within the province provides a reasonable estimate for the long-term rate of seismicity. Geological estimates of deformation rates are lower than that of geodesy or seismicity due to limited data. We focus on a particular, small region for more detailed analysis of ground motion prediction and amplification. The Reno-Sparks urban region (population ˜400,000) is located in a fault-controlled basin that is about 13 km wide and 21 km long. Despite the small basin size and depth, local basin effects are significant. Both data and synthetic modeling show that the 3D basin structure strongly influences ground motion within the basin. Site characteristics are assessed at twenty-one seismic stations in the region. Shallow shear wave velocities are measured using the refraction microtremor (ReMi) technique (Louie, 2001). Average velocities to depths of 30 m and 100 m are compared with local geological and soil classifications. Generalized geological classifications show some variations in unit averages of the measured velocities, variations between units are much smaller than the standard deviations of velocities within units having multiple measurements. Predictions of site velocities based on soil weight percent of gravel, sand, silt, and clay fall within +/-20% of measured values for all but two of the 21 sites. Ground motions from local earthquakes are used to ascertain empirical site amplification effects within the basin relative to a nearby rock site using the soil to rock spectral ratio technique. Most site response functions within the basin are mainly flat, but do show relative amplification. Some sites do show resonant peaks. These empirical site effects are compared with site conditions evaluated using average shallow shear

    The ecological security index (ESI) system including 27 indices for Heilongjiang Province was built up with the pressure-state-response (P-S-R) model. The weights of the indices were determined by analytical hierarchy process (AHP) and the ecological security status classification was evaluated by the ESI model for the years of 2000-2005. Then the development trend of ecological security from 2006 to 2010 was forecasted with the grey dynamic model. The results showed that the ecological security ranked the V grade in 2000 and the III grade in 2005, indicating the increase of ecological security. The forecasting results show that the ecological security will be the III grade for 2006, the II grade for 2007-2009, and the I grade for 2010 (ideal security). Thus it can be seen that the ecological security is ascending year by year, and the ecological environment quality is obviously improved with the implementation of eco-province construction since 2000. Through the effective facilitation of eco-province construction etc., the sustainable and healthy development of ecological security will be finally realized in Heilongjiang Province.

  12. Southwestern Svalbard Basement Province: current state of knowledge and open questions

    Caledonian basement of the Svalbard Archipelago is divisible into three provinces, namely Northeastern, Northwestern and Southwestern. The latter is recently a matter of lively debate, since new evidence for Tonian magmatism (Grenville-Sweconorwegian) and late Neoproterozoic metamorphism (Torellian) has been provided. Moreover, early Caledonian high-pressure rocks known from this area seem to be much more widespread than previously thought. These new discoveries call for re-interpretation of the geological history of the Southwestern Basement Province (SBP) as well as re-consideration of its paleogeographic position prior to the Caledonian orogeny. Yet another factor, which is causing uncertainties in the up-to-date understanding of the SBP, results from the fact that several unconnected groups of geologists have been working in this area. Here, we propose a new tectonostratigraphical scheme for the SBP, which summarizes current state of knowledge and unifies several, previously vaguely connected geological units. However, there is still a need to answer critical questions about the age and tectonostratigraphical position of some uncertain geological successions. These include mainly high-grade rocks exposed in the northern part of Oscar II Land (mostly garnet-bearing mica schists of the Kongsvegen Group), on Prins Karls Forland (garnet-bearing mica schists and amphibolites of the Pinkie Group), central Nordenskiöld Land (unnamed retro-blueschists) and southernmost Sørkapp Land (unnamed garnet-bearing mica schists). Moreover, age and position of widely recognized diamictites (Comfortless, Bellsund, Lågneset and Ferrierpiggen groups) are dubious. Also, nothing is known about quite widespread, mostly carbonaceous and presumably early Palaeozoic sediments of northern Wedel Jarlsberg Land. An unequivocal tectonic scenario for the SBP and inter-connections with the two other basement provinces cannot be proposed before comprehensive structural, geochronological and

    Seismic-hazard evaluations in the eastern United States must be based on interpretations of the composition and form of Proterozoic basement-rock terranes and overlying Paleozoic strata, and on factors that can cause relative movements among their units, rather than Phanerozoic orogenic structures, which may be independent of modern tectonics. The tectonic-province concept is a major part of both probabilistic and deterministic seismic-hazard evaluations, yet those that have been proposed to date have not attempted to geographically correlate modern earthquakes with regional basement structure. Comparison of basement terrane (megablock) boundaries with the spatial pattern of modern seismicity may lead to the mechanically sound definition of tectonic provinces, and thus, better seismic-hazard evaluation capability than is currently available. Delineation of megablock boundaries will require research on the many factors that affect their structure and movement. This paper discusses and groups these factors into two broad categories-megablock tectonics in relation to seismicity and regional horizontal-compressive stresses, with megablock tectonics divided into subcategories of basement, overlying strata, regional lineaments, basement tectonic terranes, earthquake epicenter distribution, and epeirogeny, and compressive stresses divided into pop-ups and the contemporary maximum horizontal-compressive stress field. A list presenting four to nine proposed research topics for each of these categories is given at the end.

    To effectively conserve migratory landbirds, we need to be involved in conservation beyond our political borders. This has been a central tenet of Partners in Flight (PIF) since the initiative began in 1990 with a focus on Nearctic-Neotropical migrants. Implementation of this concept has also been fundamental to the success of the North American Waterfowl Management Plan (e.g., NAWMP 2004). Actions by individual states, provinces and territories are key to the success of PIF efforts at the continental scale, and great progress has been made in recent years though various initiatives. Currently, U.S. state Wildlife Action Plans are outlining a vast array of actions to benefit priority species. However, it is also very important to take action in regions that support these same species at the other end of their migratory movements, to ensure effective protection year-round (Rappole et al. 1983, Webster and Marra 2005, Elliott et al. 2005). For instance, conservation action is needed on the wintering grounds for many birds that breed in Canada and the U.S. but spend a large portion of their annual cycle in Mexico, the West Indies, Central and/or South America. In this document we use maps to summarize migratory connections between individual U.S. states, Canadian provinces & territories and the regions that support the same birds at the other end of migration. The maps give a general picture of where birds go, providing a starting point for targeting action. With this information in hand, decision-makers can explore partnerships and mechanism that would help further conservation action outside their bordersa?|

    This dataset represents the area of each physiographic province (Fenneman and Johnson, 1946) in square meters, compiled for every catchment of NHDPlus for the conterminous United States. The source data are from Fenneman and Johnson's Physiographic Provinces of the United States, which is based on 8 major divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock type and structure, and geologic and geomorphic history (Fenneman and Johnson, 1946). The NHDPlus Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first widely used in New England, and thus referred to as "the New England Method." This technique involves "burning in" the 1:100,000-scale NHD and when available building "walls" using the National Watershed Boundary Dataset (WBD). The resulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method produces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus dataset is organized by 18 Production Units that cover the conterminous United States. The NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's Major River Basins (MRBs, Crawford and others, 2006). MRB1, covering the New England and Mid-Atlantic River basins, contains NHDPlus Production Units 1 and 2. MRB2, covering the South Atlantic-Gulf and Tennessee River basins

    We map apparent attenuation beneath the continental United States through an analysis of ~16 deep-focus teleseismic events recorded by the USArray Transportable Array. For each event, we stack the best quality recordings to generate a source estimate and then apply an attenuation operator to the source estimate using a range of t* values to fit the record at each station. The regional attenuation pattern is extracted from the ensemble of observations using a regularized inversion scheme. Preliminary results from the analysis of four events show good correlation with tectonic boundaries. The lowest apparent attenuation occurs in the upper Midwest, and corresponds to the Superior Craton; while high apparent attenuation dominates outside the cratonic continent as defined by the Rocky Mountain, Ouachita and Appalachian fronts. Our results indicate that different lithospheric provinces have distinct attenuation signatures that are consistent with expectations.

    Although the conterminous USA has a long history of ichthyological exploration, the description of biogeographical provinces has been ad hoc. In this study we quantitatively determined fish faunal provinces and interpreted them in the context of the geological history of North America. We also evaluated influences of major river basin occupancy and contemporary environmental factors on provincial patterns. Our data set comprised 794 native fishes, which we used to generate a presence and absence matrix for U.S. Geological Survey (USGS) four-digit hydrologic units. Three nested data sets were analysed separately: primary freshwater families, continental freshwater families (including primary and secondary families) and all freshwater families (including primary, secondary and peripheral families). We used clustering analysis to delimit faunal breaks and one-way analysis of similarity (ANOSIM) to determine significance among clusters (i.e. provinces). We used an indicator-species analysis to identify species that contributed most to province delineations and a similarity-percentage (SIMPER) analysis to describe the relative influence of representatives from each category (i.e. primary, secondary, peripheral) on provincial boundaries. Lastly, we used a parsimony redundancy analysis to determine the roles of historical (i.e. major river basin) and contemporary environmental factors in shaping provinces. Analysis of the nested data sets revealed lessening provincial structure with inclusion of more families. There were 10 primary freshwater provinces, 9 continental freshwater provinces and 7 all freshwater provinces. Major basin occupancy, but not contemporary environmental factors, explained substantial variance in faunal similarities among provinces. However, provincial boundaries did not conform strictly to modern river basins, but reflected river-drainage connections of the Quaternary. Provinces represent broad-scale patterns of endemism and provide a starting point

    Zircon and monazite U-Pb geochronology of rocks in the western Mojave province of the southwest US reveals that the Proterozoic arc exposed there shares an intrusive and deformational history with rocks exposed further east in the Yavapai and Mazatzal belts after approximately 1780 Ma. Consequently, it seems likely that the Mojave province was contiguous with these other Laurentian provinces by that time. Isotopic and geochronologic data also suggest that Mojave province plutonic rocks inherit their distinctive isotopic compositions, at least in part, from an enriched lithospheric mantle source and interaction with sedimentary rocks containing Archean detritus.

    As the world's most populous country, China has the world's largest number of rare disease groups in terms of prevalence. However, the country has no system of registering cases of most rare diseases, so there is very little documented information on the epidemiology of those diseases. The purpose of this study was to study the state of rare disease research and survey doctors in Shandong Province regarding their level of awareness of rare diseases. Types of rare diseases and numbers of cases were tallied and their geographical distribution over the decades was analyzed. Eight hundred and twenty-four doctors in tertiary hospitals and maternity and child care hospitals were surveyed by questionnaire. Data were descriptively analyzed and a map of disease distribution was created. Articles about rare diseases were retrieved from the Chinese Biomedical Literature Database to provide pertinent data. This study yielded 5,749 cases of 323 different types of rare diseases. The survey found that doctors lack awareness of research on rare diseases. An authoritative and information-rich platform for rare disease research is urgently needed. Key steps are to study epidemiological and statistical techniques and then obtain available data to provide a basis for the definition and regulation of rare diseases in China.

    2012-01-01

    Background This study investigated the extent and predictors of condom use and condom refusal in the Free State province in South Africa. Methods Through a household survey conducted in the Free Sate province of South Africa, 5,837 adults were interviewed. Univariate and multivariate survey logistic regressions and classification trees (CT) were used for analysing two response variables ‘ever used condom’ and ‘ever refused condom’. Results Eighty-three per cent of the respondents had ever used condoms, of which 38% always used them; 61% used them during the last sexual intercourse and 9% had ever refused to use them. The univariate logistic regression models and CT analysis indicated that a strong predictor of condom use was its perceived need. In the CT analysis, this variable was followed in importance by ‘knowledge of correct use of condom’, condom availability, young age, being single and higher education. ‘Perceived need’ for condoms did not remain significant in the multivariate analysis after controlling for other variables. The strongest predictor of condom refusal, as shown by the CT, was shame associated with condoms followed by the presence of sexual risk behaviour, knowing one’s HIV status, older age and lacking knowledge of condoms (i.e., ability to prevent sexually transmitted diseases and pregnancy, availability, correct and consistent use and existence of female condoms). In the multivariate logistic regression, age was not significant for condom refusal while affordability and perceived need were additional significant variables. Conclusions The use of complementary modelling techniques such as CT in addition to logistic regressions adds to a better understanding of condom use and refusal. Further improvement in correct and consistent use of condoms will require targeted interventions. In addition to existing social marketing campaigns, tailored approaches should focus on establishing the perceived need for condom-use and

    This tabular data set represents the area of each physiographic province (Fenneman and Johnson, 1946) in square meters, compiled for every MRB_E2RF1 catchment of selected Major River Basins (MRBs, Crawford and others, 2006). The source data are from Fenneman and Johnson's Physiographic Provinces of the United States, which is based on 8 major divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock type and structure, and geologic and geomorphic history (Fenneman and Johnson, 1946).The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011). Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), the Pacific Northwest (MRB7) river basins, and California (MRB8).

    The results of a soil geochemical survey of the Canadian Maritime provinces and the northeast states of the United States are described. The data presented are for the <2-mm fraction of the surface layer (0-5 cm depth) and C horizons of the soil. Elemental determinations were made by ICP-MS following two digestions, aqua regia (partial dissolution) and a strong 4-acid mixture (near-total dissolution). The preliminary results show that Hg and Pb exhibit elevated abundances in the surface layer, while As and Ni exhibit abundances that can be attributed to the geological provenance of the soil parent materials.

    The distribution of deformation within the Basin and Range province was determined from 1992, 1996, and 1998 surveys of a dense, 800-kilometer- aperture, Global Positioning System network, Internal deformation generally follows the pattern of Holocene fault distribution and is concentrated near the western extremity of the province, with lesser amounts focused near the eastern boundary. Little net deformation occurs across the central 500 kilometers of the network in western Utah and eastern Nevada. Concentration of deformation adjacent to the rigid Sierra Nevada block indicates that external plate-driving forces play an important role in driving deformation, modulating the extensional stress field generated by internal buoyancy forces that are due to lateral density gradients and topography near the province boundaries.

    Household food security impacts heavily on quality of life. We determined factors associated with food insecurity in 886 households in rural and urban Free State Province, South Africa. Significantly more urban than rural households reported current food shortage (81% and 47%, respectively). Predictors of food security included vegetable production in rural areas and keeping food for future use in urban households. Microwave oven ownership was negatively associated with food insecurity in urban households and using a primus or paraffin stove positively associated with food insecurity in rural households. Interventions to improve food availability and access should be emphasized.

    Land as a major collective human property faces a great deal of threats and eventual degradation from both natural and human causal factors across the globe. But for the central role of land in human's sustenance and quality living, man cannot afford to lose its natural asset and as such takes mitigating or remedial actions to save and restore his land for sustainable use. In view of this, the study assessed the causal factors of land degradation in urban areas of Abeokuta and effectiveness and sustainability of the taken remedial actions to stem the tide of land degradation in the study area. The selected communities were purposively selected based on the observed prevalence of degraded lands in the areas. A qualitative research approach which encompasses observational techniques - participant/field observation, interactive discussion and photographic capturing, was used for collection of data on land degradation in the study area. A combination of phenomenological, inductive thematic analysis and conversation/discourse analysis was employed for data analysis. The results showed land gradients/slopes, rainfall, run-offs/erosion, land-entrenched foot impacts, sand scraping/mining, poor/absence of drainage system and land covers as causal factors of land degradation in the study area. The employed remedial actions for restoration of degraded land included filling of drenches with sand bags, wood logs, bricks and stones, and sand filling. The study though observed that filling of drenches caused by erosion with rubles/stones and construction of drainage were effective remedial actions, good drainage system was presumed to be the most appropriate and sustainable remedial action for land restoration in the study area.

    This report presents final technical results for the project Simulation Framework for Regional Geologic CO{sub 2} Storage Infrastructure along Arches Province of the Midwest United States. The Arches Simulation project was a three year effort designed to develop a simulation framework for regional geologic carbon dioxide (CO{sub 2}) storage infrastructure along the Arches Province through development of a geologic model and advanced reservoir simulations of large-scale CO{sub 2} storage. The project included five major technical tasks: (1) compilation of geologic, hydraulic and injection data on Mount Simon, (2) development of model framework and parameters, (3) preliminary variable density flow simulations, (4) multi-phase model runs of regional storage scenarios, and (5) implications for regional storage feasibility. The Arches Province is an informal region in northeastern Indiana, northern Kentucky, western Ohio, and southern Michigan where sedimentary rock formations form broad arch and platform structures. In the province, the Mount Simon sandstone is an appealing deep saline formation for CO{sub 2} storage because of the intersection of reservoir thickness and permeability. Many CO{sub 2} sources are located in proximity to the Arches Province, and the area is adjacent to coal fired power plants along the Ohio River Valley corridor. Geophysical well logs, rock samples, drilling logs, and geotechnical tests were evaluated for a 500,000 km{sup 2} study area centered on the Arches Province. Hydraulic parameters and historical operational information was also compiled from Mount Simon wastewater injection wells in the region. This information was integrated into a geocellular model that depicts the parameters and conditions in a numerical array. The geologic and hydraulic data were integrated into a three-dimensional grid of porosity and permeability, which are key parameters regarding fluid flow and pressure buildup due to CO{sub 2} injection.

    To evaluate the capacity of health facilities in Southern Province, Zambia, to perform routine obstetric care and emergency obstetric and neonatal care (EmONC). Surveys were completed at 90 health centers and 10 hospitals between September 1, 2011, and February 28, 2012. An expanded set of signal functions for routine care and EmONC was used to assess the facilities' capacity to provide obstetric and neonatal care. Interviews were completed with 172 health workers. Comprehensive EmONC was available in only six of 10 hospitals; the remaining four hospitals did not perform all basic EmONC signal functions. None of the 90 health centers performed the basic set of EmONC signal functions. Performance of routine obstetric care functions, health worker EmONC training, and facility infrastructure and staffing varied. Assessment of the indicators for routine care revealed that several low-cost interventions are currently underused in Southern Province. There is substantial room for improvement in emergency and routine obstetric and neonatal care at the surveyed facilities. Efforts should focus on improving infrastructure and supplies, EmONC training, and adherence to the UN guidelines for routine and emergency obstetric care.

    The impact Large Igneous Province (LIP) volcanism may have had on paleoclimate, fauna and flora is still controversy. Inter-lava field plant ecosystems have the potential to record in detail the effects LIPs had on the environment in the immediate vicinity of volcanic activity. The Miocene Columbia River Flood Basalt Province (CRBP), Washington State, USA, provides excellent exposure of an entire LIP stratigraphy and offers a detailed record of inter-basaltic plant ecosystems throughout LIP evolution. The CRBP lava field comprise numerous basaltic lava flows that are intercalated with fluvial and lacustrine sediments which formed during phases of volcanic quiescence. The LIP volcanic evolution is characterised by an initial phase of high eruption volumes and eruptions rates, which is followed by waning volcanism associated with longer interbed intervals. Inter-lava field plant ecosystems are expected to correlate with phases of volcanic evolution: short interbed intervals should be dominated by early seral succession, while longer intervals should record more mature seral successions. The palynological record of the sedimentary interbeds however indicates a decline in successional status within the long interbed intervals of CRBP stratigraphy. An integrated analysis of sedimentary facies and geochemistry suggests intense volcanic ash fall derived from the adjacent Yellowstone hot spot as a major trigger for repetitive successional re-setting. This implies that inter-lava field ecosystem maturity was controlled by extrinsic forcing, and argues against environmental changes solely driven by LIPs of similar scale and magnitude to that of the CRBP.

    Constraining the deformation history of western North America is important for understanding how tectonic plates accommodate large kinematic changes along their margins. Since the Miocene, a large portion of Pacific - North American plate motion has been accommodated by extension in the Basin and Range Province between the Sierra Nevada and the Colorado Plateau. Although many ranges in the province are physiographically similar, they developed with significant spatiotemporal variations in range-scale fault displacements and rates. Here, we examine the landscape response to changing fault-slip rates by comparing existing thermochronologic data to new geomorphic observations. Low-temperature thermochronologic data from the northwestern Nevada portion of the Basin and Range indicate that faulting began ~12 Ma, with a second phase of rapid slip beginning ~4-3 Ma documented in some ranges. We used the NED DEM (10 m resolution) to measure channel morphology and geologic maps to account for lithologic variations and faults. Bedrock channel profile analyses from several uplifted footwalls (Pine Forest Range, Santa Rosa Range, Jackson Mountains) reveal patterns in concavity (θ) and normalized steepness index (ksn) indicative of unsteady slip, even in footwalls where thermochronologic data does not exist or is not capable of identifying the recent uplift. Some channels possess mean concavity indices of θmean = ~0.6, which falls within the range for channels in equilibrium (0.35 < θ < 0.6). However, in many cases, channel profiles possess prominent convexities that separate them into two distinct segments. Mean ksn values of the segments below these knickpoints are ~3 times greater than those above them (ksn = ~200 vs. ~70 m0.9). Concavity indices for segments below the knickpoints are significantly lower (θmean ~0.2) than the higher elevation segments (θmean ~0.5), suggesting that while the higher segments are in equilibrium, the lower segments are in the process of

    The hydrogeology of the Basin and Range Physiographic Province in parts of Arizona, California, New Mexico, Utah, and most of Nevada was classified at basin and larger scales to facilitate information transfer and to provide a synthesis of results from many previous hydrologic investigations. A conceptual model for the spatial hierarchy of the hydrogeology was developed for the Basin and Range Physiographic Province and consists, in order of increasing spatial scale, of hydrogeologic components, hydrogeologic areas, hydrogeologic flow systems, and hydrogeologic regions. This hierarchy formed a framework for hydrogeologic classification. Hydrogeologic areas consist of coincident ground-water and surface-water basins and were delineated on the basis of existing sets of basin boundaries that were used in past investigations by State and Federal government agencies. Within the study area, 344 hydrogeologic areas were identified and delineated. This set of basins not only provides a framework for the classification developed in this report, but also has value for regional and subregional purposes of inventory, study, analysis, and planning throughout the Basin and Range Physiographic Province. The fact that nearly all of the province is delineated by the hydrogeologic areas makes this set well suited to support regional-scale investigations. Hydrogeologic areas are conceptualized as a control volume consisting of three hydrogeologic components: the soils and streams, basin fill, and consolidated rocks. The soils and streams hydrogeologic component consists of all surface-water bodies and soils extending to the bottom of the plant root zone. The basin-fill hydrogeologic component consists of unconsolidated and semiconsolidated sediment deposited in the structural basin. The consolidated-rocks hydrogeologic component consists of the crystalline and sedimentary rocks that form the mountain blocks and basement rock of the structural basin. Hydrogeologic areas were

    Severe and prolonged droughts between 1961 and 1988, combined with increased demands for freshwater supplies in the United States, have resulted in a critical need to assess the potential for development of ground- and surface-water supplies. Rapid industrial growth and urban expansion have caused existing freshwater supplies to be used at or near maximum capacity. Begun in 1978, the Regional Aquifer-System Analysis (RASA) Program of the U.S. Geological Survey (USGS) is a systematic effort to study a number of the Nation's most important aquifer systems, which, in aggregate, underlie much of the country and represent an important component of the Nation's total water supply. The broad objective for each of the 28 studies in the program is to assemble geologic, hydrologic, and geochemical information, to analyze and develop an understanding of the system, and to develop predictive capabilities that will contribute to the effective management of the system.In 1988, as part of the RASA Program, the USGS began a 6-year study of the ground-water resources of parts of 11 States in the Eastern United States (Swain and others, 1991). The study was designated the Appalachian Valley and Piedmont Regional Aquifer-System Analysis (APRASA). The APRASA team investigated ground-water resources primarily in the unglaciated part of the Valley and Ridge, the Blue Ridge, the New England, and the Piedmont Physiographic Provinces (fig. 1). For the purposes of this report, the small area in the New England Physiographic Province that is within the study area in New Jersey and Pennsylvania was considered part of the Piedmont Physiographic Province. The results of the APRASA are contained in about 50 reports and abstracts, including reports on simulation of ground-water flow in three type areas, this atlas, and chapters in Professional Paper 1422. These chapters include the summary (Chapter A), descriptions of recharge rates and surface- and ground-water relations (Chapter B

  18. Geodetic Constraints on Strain Transfer Between the Colorado Plateau and the Basin and Range Province, Southwestern United States

    NASA Astrophysics Data System (ADS)

    2008-12-01

    Geodetic measurements of crustal deformation in the western United States have provided unprecedented constraints on the kinematics of deformation of the Pacific-North America plate boundary zone. In particular, it is now well established that deformation in the northern Basin and Range Province is mostly taking place along its western and eastern margins with very little internal strain in the middle part of the Province. Westward motion of the bulk of the Province of 2-3 mm/yr relative to North America/Colorado Plateau is being accommodated along a roughly 100-km wide deformation zone centered near the Wasatch fault. We present a new model of how these 2-3 mm/yr of relative motion are being accommodated further south using velocities of continuous GPS sites in the area, mainly those belonging to the BARGEN and EarthScope's Plate Boundary Observatory networks. The velocity field allows for an interpretation in which the relatively narrow deformation zone across the Wasatch broadens southward to about 700-km wide in the southern Basin Range at the latitude of southern Arizona. If true, the idea of an autonomous, rigid, and independently moving Colorado Plateau needs to be reassessed. Alternatively we find that subsets of the GPS velocities on the Plateau can be interpreted as having rigid-body rotation, but the Euler pole of the rotation is highly dependent on which subset of stations is being considered. Consequently, the inferred motion along the Plateau's margins vary considerably between models and can only be tested by acquiring more geodetic data or by considering independent kinematic indicators such as earthquake slip vectors. Relative to sites on the southwestern Plateau we observe 1.7 and 1.2 mm/yr of westward motion of sites on the Nevada Test Site and Spring Mountains (southern Nevada), respectively, while we observe no extension directly across the Hurricane-Toroweap fault system (the Plateau's western physiographic boundary at this latitude). These

    2014-06-01

    We use data from western U.S. GPS networks to estimate the rate, pattern, and style of tectonic deformation of the central Basin and Range Province (BRP). Previous geodetic investigations have found the crust of eastern Nevada and western Utah to act as a rigid microplate, with zero deformation rates to within measurement uncertainty. Observed transients in GPS time series have led others to propose a megadetachment model, predicting that the central BRP behaves as a microplate, but with time-varying translation. Here we reassess these hypotheses, benefiting from a significant increase in GPS stations and time span, and innovations in analysis techniques. Our results show that the BRP crust deforms everywhere and all the time. In a group of 24 stations between longitude -113.5° and -116.8°, we find strain rates of 1.9 ± 0.2 × 10-9 yr-1 extension directed N55°W and 2.2 ± 0.2 × 10-9 yr-1 contraction directed N35°E, inconsistent with microplate behavior. The linearity of time series of strain from GPS station triplets is inconsistent with episodic translation of quasi-rigid domains. One exception is station EGAN that exhibits nonlinear motion not found in adjacent stations. The dominant signal in Nevada is distributed shear consistent with Pacific/North America relative plate motion, suggesting that stresses are transmitted through the lithosphere at least 800 km from the plate boundary. The observed active extension is consistent with earthquake focal mechanisms and is in agreement with integrated rates estimated from earthquake geology. Our results do not support the proposed megadetachment in the BRP.

  20. Using GPS to Separate Transient and Steady Extension in the Basin and Range Province, Western United States

    2011-12-01

    The Basin and Range Province (BRP) of the western United States is an integral part of the Pacific/North America plate boundary deformation zone, and as such experiences tectonic deformation and large earthquakes that can threaten communities in Nevada, Utah, Arizona, and parts of Idaho and Oregon. The active deformation over the majority of the 800 km wide Province occurs at rates ~1 mm/yr over hundreds of kilometers, and only recently has become definitively measured with GPS. However, recent geological and geophysical studies of the BRP have come to conflicting conclusions about how the deformation occurs. For example, while earlier geodetic studies suggested that the North American Plate is non-deforming, others recent studies found evidence for episodic, province-scale, but small magnitude deformation events. Recent paleoseismic trenching of faults along a transect across the entire BRP find low-rate normal faulting and extension, distributed roughly evenly across the Province. These three different views of how the plate deforms imply extremely different dynamic modes of extension of continental lithosphere, and thus it is not possible that all three are correct. We will present recent results from the EarthScope Plate Boundary Observatory (PBO) and Mobile Array of GPS for Nevada Transtension (MAGNET) GPS networks that are now measuring these single digit nanostrain/yr deformation signals, and use them to distinguish between these competing hypotheses. We focus on the BRP and transition to the Colorado Plateau, where PBO and MAGNET networks measure the slow but active domains that transfer deformation between the major elements of the PA/NA plate boundary. To better understand BRP deformation we are: 1) processing GPS data using the latest software and models, 2) systematically generating a catalog of geodetic transients for the BRP GPS stations, indicating which could be explained by geophysical events, 3) developing models of the viscoelastic response from

    This paper investigates the perceived and observed trends of associated health risks with seasonal climate variability and identifies types of and preference for adaptation strategies that are available at households and community levels in Oke-Ogun region, Nigeria. The study made use of household survey and rapid appraisal through focus group discussion and key informant interviews. For a short term climate-health impacts analysis, cases of notable diseases were correlated with monthly mean temperature and rainfall for the period 2006 and 2008. The findings show similar trends in relation to local perception on climate-health risks and observed cases of some notable diseases during seasonal changes. Diarrhea, measles and malaria were prevalent during dry season, while flu cases increased at the onset of harmattan and monsoon of rainy season. Available adaptation strategies are autonomous, mostly in the form of treatment measures such as consultation with medical officers in hospitals (17.5%), self-medication (34%) and use of traditional therapy such as herbs (48.5%). Traditional therapy is mostly preferred and approved based on long-term experience of the study population. © 2013 Elsevier Ltd. All rights reserved.

    In the present study, we investigated the occurrence of intersex condition, histopathological changes in the gonad and endocrine disruptor biomarker responses in Tilapia species (Tilaipia guineensis, Sarotherodon galileaus and Oreochromis niloticus) along the Ogun River, Nigeria. The study sites covered a length of 320 km and a total of 1074 tilapias were collected from three sampling sites (Abeokuta, Isheri and Ikorodu) with different degrees of anthropogenic contamination. Samples were also collected from an upstream putative control site (Igboho) along the Ogun River. Hepatic transcript levels for vitellogenin (Vtg), zona radiata (Zrp) and aromatase (cyp19a1) were analyzed using real-time PCR. Gross gonadal morphology revealed a 24% prevalence of intersex showing visible testis and ovary in phenotypic females (25.4%) or males (74.6%). The intersex condition paralleled histopathological changes (ovotestis or testis-ova) in the gonads of female and male fish, respectively. Plasma concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH), 11-ketotestosterone (11-KT) and estradiol-17β (E2) were measured using enzyme immunoassay, showing that male fish from downstream of the control site had significantly higher plasma E2, LH, and FSH concentrations compared to females. Similarly, Vtg, Zrp and cyp19a1 mRNA was significantly higher in males, compared to females. Analysis of contaminants showed the presence of 15 PCB congeners, lindane and dieldrin, and 4-iso-nonylphenol (4-iso-NP) and 4-tert-octylphenol (4-tert-OP) in fish muscle and sediment samples from Ogun River. Principal component analysis (PCA) revealed site and sex relationships between measured biological responses to groups of environmental contaminants, showing that the endocrine disruptive responses in fish were associated with biota and sediment contaminant burden. In addition, strong positive correlations were observed between male fish and Zrp, cyp19a1, E2, LH, FSH, PCBs, 4-iso

    The health financing system in the Democratic Republic of Congo (DRC) presents an extreme example of low government investment, high dependency on user fees and poor harmonization across donors. Within this context, performance-based financing mechanisms are being implemented by various donors in the expectation that they will improve health worker motivation and service delivery performance. Drawing on qualitative and quantitative data at different levels of the health system, this study focuses on one such programme in Katanga Province, which combines paying for performance (P4P) with a reduction in fees to users. Despite adding considerably to facility resources (providing the majority of the resources in the case study facilities), there was no evidence of benefits in terms of any of the service inputs, processes or outputs measured. The findings suggest that the positive effects on health worker motivation cannot be taken as a given, particularly, when staff are often expected to increase their workload to achieve the performance objectives and when another source of income, the income from user fees, may be reduced due to a fall in the prices of services. Moreover, in a context where health workers were already almost entirely dependent on users for their remuneration before the donor programme was introduced, the incentive effects of a performance contract may be muted. In addition, other income sources have particular value for staff, it seems-even though salaries and government allowances were low, and frequently delayed, health workers were highly dissatisfied at not receiving them. Salaries were seen as a more assured and long-term source of funding and an important recognition of their role as agents of the state. The authors conclude that while there may be a role for P4P in fragile contexts such as the DRC, to be effective it needs to be rooted in wider financing and human resource policy reforms.

    The treatment outcomes for large-scale public antiretroviral therapy (ART) programs in developing countries, although promising, are still preliminary. The scaling-up of ART in resource-limited settings is inevitably hampered by human resource shortages. Therefore, community support for ART patients may play an important role in achieving favorable treatment outcomes. This study aimed to extend the current literature by investigating how immunological and virological responses to ART, measured at three points in time (after six, 12, and 24 months of ART), are influenced by patient characteristics (age, sex), health literacy (educational level and knowledge about HIV/AIDS), baseline CD4 cell count, baseline viral load, and three forms of community support (treatment buddy, community health worker [CHW], and HIV/AIDS support group). Cross-lagged regression analysis was used to test these relationships in a sample of 268 patients enrolled in the public-sector ART program of the Free State Province of South Africa (2004-2007). After 24 months of ART, 76.4% of patients were classified as treatment successes (viral load < 400 copies/mL, CD4 > or = 200 cells/microL), compared with 64.1% at 12 months and 46.1% at six months. When we examined the predictors of ART success, baseline health and all three community support initiatives had a positive effect on ART outcomes after six months, whereas patient characteristics had little effect. Six months later, patients with the support of a treatment buddy, CHW, or support group had better ART outcomes, whereas the impact of baseline health had diminished. After two years of treatment, community support again emerged as the most important predictor of treatment success. This study confirms that the ART provided by South African public-sector health services is effective. These results provide evidence from the field that communities can be mobilized to sustain these favorable outcomes under conditions of limited human resources

    The Arches Province in the Midwestern U.S. has been identified as a major area for carbon dioxide (CO{sub 2}) storage applications because of the intersection of Mt. Simon sandstone reservoir thickness and permeability. To better understand large-scale CO{sub 2} storage infrastructure requirements in the Arches Province, variable density scoping level modeling was completed. Three main tasks were completed for the variable density modeling: Single-phase, variable density groundwater flow modeling; Scoping level multi-phase simulations; and Preliminary basin-scale multi-phase simulations. The variable density modeling task was successful in evaluating appropriate input data for the Arches Province numerical simulations. Data from the geocellular model developed earlier in the project were translated into preliminary numerical models. These models were calibrated to observed conditions in the Mt. Simon, suggesting a suitable geologic depiction of the system. The initial models were used to assess boundary conditions, calibrate to reservoir conditions, examine grid dimensions, evaluate upscaling items, and develop regional storage field scenarios. The task also provided practical information on items related to CO{sub 2} storage applications in the Arches Province such as pressure buildup estimates, well spacing limitations, and injection field arrangements. The Arches Simulation project is a three-year effort and part of the United States Department of Energy (U.S. DOE)/National Energy Technology Laboratory (NETL) program on innovative and advanced technologies and protocols for monitoring/verification/accounting (MVA), simulation, and risk assessment of CO{sub 2} sequestration in geologic formations. The overall objective of the project is to develop a simulation framework for regional geologic CO{sub 2} storage infrastructure along the Arches Province of the Midwestern U.S.

    Although the estimated incidence and prevalence of juvenile-onset recurrent respiratory papillomatosis (JORRP) has been determined in countries in North America and Europe and in Australia, no studies have attempted to determine the incidence or prevalence of JORRP in African countries. The aim of this study is to determine the incidence and prevalence of JORRP in the Free State province of South Africa and Lesotho. This was a retrospective study in which the records of all patients with JORRP from the Free State province of South Africa or Lesotho treated at Universitas Academic Hospital or by otorhinolaryngologists in private practice between 1 January 2011 and 31 December 2013 were reviewed. The estimated incidence and prevalence of JORRP in the Free State were 1.34 and 3.88 per 100,000 population respectively while the estimated incidence and prevalence in Lesotho were 0.49 and 1.04 per 100,000 population respectively. However, these figures are probably an underestimation. The incidence and prevalence calculated for the Free State were generally higher than those found in other studies, while those calculated for Lesotho was similar to those obtained in other studies.

    The Appalachian Valley and Piedmont Regional Aquifer-System Analysis study (1988-1993) analyzed rock types in the 142,000-square-mile study area, identified hydrogeologic terranes, determined transmissivity distributions, determined the contribution of ground water to streamflow, modeled ground-water flow, described water quality, and identified areas suitable for the potential development of municipal and industrial ground-water supplies. Ground-water use in the Valley and Ridge, the Blue Ridge, and the Piedmont Physiographic Provinces exceeds 1.7 billion gallons per day.Thirty-three rock types in the study area were analyzed, and the rock types with similar water-yielding characteristics were combined and mapped as 10 hydrogeologic terranes. Based on well records, the interquartile ranges of estimated transmissivities are between 180 to 17,000 feet squared per day (ft2/d) for five hydrologic terranes in the Valley and Ridge; between 9 to 350 ft2/d for two terranes in the Blue Ridge; and between 9 to 1,400 ft2/d for three terranes in the Piedmont Physiographic Province. Based on streamflow records, the interquartile ranges of estimated transmissivities for all three physiographic provinces are between 290 and 2,900 ft2/d. The mean ground-water contribution to streams from 157 drainage basins ranges from 32 to 94 percent of mean streamflow with a median of 67 percent. In three small areas in two of the physiographic provinces, more than 54 percent of ground-water flow was modeled as shallow and local. Although ground-water chemical composition in the three physiographic provinces is distinctly different, the water generally is not highly mineralized, with a median dissolved-solids concentration of 164 milligrams per liter, and is mostly calcium, magnesium, and bicarbonate. Based on aquifer properties and current pumpage, areas favorable for the development of municipal and industrial ground-water supplies are underlain by alluvium of glacial origin near the

    The main aim of the study was to propose a model for predicting the peak expiratory flow rate (PEFR) of Nigerian workers in a cement factory. Sixty randomly selected non-smoker and healthy workers (30 in production sections, 30 in the administrative section of the factory) participated in the study. Their physical characteristics and PEFR were measured. Multiple correlations using SPSS version 16.0 were performed on the data. The values of PEFR, using the obtained model, were compared with the measured values using a two-tailed t test. There were positive correlations among age, height and PEFR. A prediction equation for PEFR based on age, height, weight and years of exposure (experience) was obtained with R² = .843 (p < 0.001). The developed model will be useful for the management in determining PEFR of workers in the cement industry for possible medical attention.

    1978-01-01

    This summary of geochemical exploration in the Basin and Range Province is another in the series of reviews of geochemical-exploration applications covering a large region; this series began in 1975 with a summary for the Canadian Cordillera and Canadian Shield, and was followed in 1976 by a similar summary for Scandinavia (Norden). Rather than adhering strictly to the type of conceptual models applied in those papers, we have made use of generalized landscape geochemistry models related to the nature of concealment of ore deposits. This study is part of a continuing effort to examine and evaluate geochemical-exploration practices in different areas of the world. Twenty case histories of the application of geochemical exploration in both district and regional settings illustrate recent developments in techniques and approaches. Along with other published reports these case histories, exemplifying generalized models of concealed deposits, provide data used to evaluate geochemical-exploration programs and specific sample media. Because blind deposits are increasingly sought in the Basin and Range Province, the use of new sample media or anomaly-enhancement techniques is a necessity. Analysis of vapors or gases emanating from blind deposits is a promising new technique. Certain fractions of stream sediments show anomalies that are weak or not detected in conventional minus 80-mesh fractions. Multi-element analysis of mineralized bedrock may show zoning patterns that indicate depth or direction of ore. Examples of the application of these and other, more conventional methods are indicated in the case histories. The final section of this paper contains a brief evaluation of the applications of all types of sample media to geochemical exploration in the arid environment of the Basin and Range Province. ?? 1978.

    This study assesses early Mesozoic provenance linkages and paleogeographic-tectonic models for the western United States based on new petrographic and detrital zircon data from Triassic and Jurassic sandstones of the "Izee" and Olds Ferry terranes of the Blue Mountains Province, northeastern Oregon. Triassic sediments were likely derived from the Baker terrane offshore accretionary subduction complex and are dominated by Late Archean (ca. 2.7-2.5 Ga), Late Paleoproterozoic (ca. 2.2-1.6 Ga), and Paleozoic (ca. 380-255 Ma) detrital zircon grains. These detrital ages suggest that portions of the Baker terrane have a genetic affinity with other Cordilleran accretionary subduction complexes of the western United States, including those in the Northern Sierra and Eastern Klamath terranes. The abundance of Precambrian grains in detritus derived from an offshore complex highlights the importance of sediment reworking. Jurassic sediments are dominated by Mesozoic detrital ages (ca. 230-160 Ma), contain significant amounts of Paleozoic (ca. 290, 380-350, 480-415 Ma), Neoproterozoic (ca. 675-575 Ma), and Mesoproterozoic grains (ca. 1.4-1.0 Ga), and have lesser quantities of Late Paleoproterozoic grains (ca. 2.1-1.7 Ga). Detrital zircon ages in Jurassic sediments closely resemble well-documented age distributions in transcontinental sands of Ouachita-Appalachian provenance that were transported across the southwestern United States and modified by input from cratonal, miogeoclinal, and Cordilleran-arc sources during Triassic and Jurassic time. Jurassic sediments likely were derived from the Cordilleran arc and an orogenic highland in Nevada that yielded recycled sand from uplifted Triassic backarc basin deposits. Our data suggest that numerous Jurassic Cordilleran basins formed close to the Cordilleran margin and support a model for moderate post-Jurassic translation (~400 km) of the Blue Mountains Province. ?? 2011 Geological Society of America.

    Each province profile figure consists of five strip charts and a boxplot. The five strip charts display for individual plays the following reservoir-fluid and reservoir properties: A, oil density (American Petroleum Institute [API] gravity in degrees); B, computed pseudo-Dykstra-Parsons coefficient; C, reservoir porosity (in percent); D, reservoir permeability (in millidarcies); and E, estimates of the original oil in place (OOIP) per unit volume of reservoir rock (in barrels per acre-foot). The OOIP per unit volume of reservoir rock is an indicator of the relative richness of the oil reservoir and is derived from estimates in the CRD of OOIP, reservoir acreage, and net pay. The net pay is the interval of productive reservoir rock. The same data for OOIP per unit volume are graphed as a strip chart (E) and a boxplot (F).

    Chemical quality of ground water, spring water, and surface water differs substantially among the three physiographic provinces. Maps showing regional variations for 18 water properties and constituents are included in this Regional Aquifer System Analysis study report. Systematic variations in water quality are due to differences in geologic and hydrologic factors that include the dominant lithology, the availability of soluble minerals, and the degree of exposure of water to rock. Most ground water in the study area is low in concentrations of dissolved minerals, is moderately hard, and is slightly acidic. Spring water is generally harder than ground water and is slightly alkaline; whereas, surface water is softer than the ground water and is also slightly alkaline.

    There are concerns as to whether South Africa's public health system has sufficient resources, human and otherwise, to ensure universal access to antiretroviral treatment (ART). We report on public sector implementation of the Comprehensive Care Management and Treatment (CCMT) programme in the Free State Province, South Africa, in particular whether the primary health care (PHC) infrastructure was able to mobilise the necessary inputs to effectively provide ART, without undermining other services within facilities. A longitudinal study was conducted of the first 16 PHC facilities accredited to provide ART in the province. The facilities were visited on three occasions over 2 years, involving both structured and open-ended interviews with professional and lay staff, and observations of available resources. The resources assessed were staffing, space, essential equipment, drug supplies and laboratory systems. Approximately one-fifth (20%) of professional nurses were allocated to the CCMT programme in the facilities, although the overall number of professional nurses increased by only 14%. This process resulted in some displacement of professional nurses towards the CCMT Programme away from other services in the facilities. However, this could have been partially compensated for by task shifting towards community health workers and the appointment of additional support staff. Staff were largely positive about the programme. Drug supplies, availability of equipment and laboratory systems, although good at the baseline, improved further over the period of observation. The lack of adequate space to accommodate the new programme was a frequently reported problem. Overall, our assessment is that the PHC infrastructure in the Free State's public health system is capable of implementing and benefiting from the CCMT programme. Nevertheless, constraints in the availability of professional staff threaten future implementation of both the CCMT and other PHC programmes.

  2. Miocene to present deformation rates in the Yakima Fold Province and implications for earthquake hazards in central Washington State, USA

    The Yakima fold province (YFP), located in the Cascadia backarc of central Washington, is a region of active distributed deformation that accommodates NNE-SSW shortening. Geodetic data show modern strain accumulation of 2 mm/yr across this large-scale fold province. Deformation rates on individual structures, however, are difficult to assess from GPS data given low strain rates and the relatively short time period of geodetic observation. Geomorphic and geologic records, on the other hand, span sufficient time to investigate deformation rates on the folds. Resolving fault geometries and slip rates of the YFP is imperative to seismic hazard assessment for nearby infrastructure, including a large nuclear waste facility and hydroelectric dams along the Columbia and Yakima Rivers. We present new results on the timing and magnitude of deformation across several Yakima folds, including the Manastash Ridge, Umtanum Ridge, and Saddle Mountains anticlines. We constructed several line-balanced cross sections across the folds to calculated the magnitude of total shortening since Miocene time. To further constrain our structural models, we include forward-modeling of magnetic and gravity anomaly data. We estimate total shortening between 1.0 and 2.4 km across individual folds, decreasing eastward, consistent with geodetically and geologically measured clockwise rotation. Importantly, we find that thrust faults reactivate and invert normal faults in the basement, and do not appear to sole into a common décollement at shallow to mid-crustal depth. We constrain spatial and temporal variability in deformation rates along the Saddle Mountains, Manastash Ridge and Umtanum Ridge anticlines using geomorphic and stratigraphic markers of topographic evolution. From stratigraphy and geochronology of growth strata along the Saddle Mountains we find that the rate of deformation has increased up to six-fold since late Miocene time.

  4. The distribution of uranium and thorium in granitic rocks of the basin and range province, Western United States

    Some secondary uranium deposits are thought to have formed from uranium derived by the weathering of silicic igneous rocks such as granites, rhyolites, and tuffs. A regional geochemical survey was made to determine the distribution of uranium and thorium in granitic rocks of the Basin and Range province in order to evaluate the potential for secondary uranium occurrences in the area. The resulting geochemical maps of uranium, thorium, and the Th:U ratio may be useful in locating target areas for uranium exploration. The granites were sampled according to a five-level, nested, analysis-of-variance design, permitting estimates to be made of the variance due to differences between:(1) two-degree cells; (2) one-degree cells; (3) plutons; (4) samples; and (5) analyses. The cells are areas described in units of degrees of latitude and longitude. The results show that individual plutons tend to differ in uranium and thorium concentrations, but that each pluton tends to be relatively homogeneous. Only small amounts of variance occur at the two degree and the between-analyses levels. The three geochemical maps that were prepared are based on one-degree cell means. The reproducibility of the maps is U > Th ??? Th:U. These geochemical maps may be used in three methods of locating target areas for uranium exploration. The first method uses the concept that plutons containing the greatest amounts of uranium may supply the greatest amounts of uranium for the formation of secondary uranium occurrences. The second method is to examine areas with high thorium contents, because thorium and uranium are initially highly correlated but much uranium could be lost by weathering. The third method is to locate areas in which the plutons have particularly high Th:U ratios. Because uranium, but not thorium, is leached by chemical weathering, high Th:U ratios suggest a possible loss of uranium and possibly a greater potential for secondary uranium occurrences to be found in the area. ?? 1981.

    Early Jurassic bimodal volcanic and intrusive rocks in southern South China show distinct associations and distribution patterns in comparison with those of the Middle Jurassic and Cretaceous rocks in the area. It is widely accepted that these rocks formed in an extensional setting, although the timing of the onset and the tectonic driver for extension are debated. Here, we present systematic LA-ICP-MS zircon U-Pb ages, whole-rock geochemistry and Sr-Nd isotope data for bimodal volcanic rocks from the Changpu Formation in the Changpu-Baimianshi and Dongkeng-Linjiang basins in southern Jiangxi Province, South China. Zircon U-Pb ages indicate that the bimodal volcanic rocks erupted at ca. 190 Ma, contemporaneous with the Fankeng basalts (~ 183 Ma). A compilation of geochronological results demonstrates that basin-scale basaltic eruptions occurred during the Early Jurassic within a relatively short interval (< 5 Ma). These Early Jurassic basalts have tholeiitic compositions and OIB-like trace element distribution patterns. Geochemical analyses show that the basalts were derived from depleted asthenospheric mantle, dominated by a volatile-free peridotite source. The calculated primary melt compositions suggest that the basalts formed at 1.9-2.1 GPa, with melting temperatures of 1378 °C-1405 °C and a mantle potential temperature (TP) ranging from 1383 °C to 1407 °C. The temperature range is somewhat hotter than normal mid-ocean-basalt (MORB) mantle but similar to an intra-plate continental mantle setting, such as the Basin and Range Province in western North America. This study provides an important constraint on the Early Jurassic mantle thermal state beneath South China.

    A major development in fishery science has been the Fulton's condition factor (CF) as a reliable physiological index of fish growth and health status (Fulton 1902). As a general rule, CF-value greater than 1 (>1) should be regarded as an indicator for good growth and health. Therefore, exposure of fish to contaminants in the environment will be expected to produce a reduction in scope for growth, since energy for growth will be allocated to overcome stressful conditions. In the present study, we hypothesized that tilapia species from Ogun River (Nigeria) are experiencing severe contaminant-induced obesogen effects leading to high CF (≥ 2) in fish with pathological alterations. The environmental obesogen hypothesis has related the interaction between environmental pollutants and PPAR isoform activation In this respect, peroxisome proliferator-activated receptors (PPARs) and biotransformation responses in relation to contaminant burden were investigated in a total of 1074 specimens of Tilapias species (Tilapia guineensis, Sarotherodon galileaus and Oreochromis niloticus) collected from three areas with different degrees of anthropogenic contamination and from a putative control site along the Ogun River. Liver mRNA expression of cytochrome cyp1 isoforms (cyp1a, 1b and 1c) and PPAR isoforms (ppar-α, β and γ) were analyzed using validated real-time PCR. Fish were also analyzed for CF and muscle contaminant burden (aliphatic and polycyclic aromatic hydrocarbons, organochlorine pesticides, and polychlorinated biphenyls). A significant increase in mRNA expression of cyp1- and ppar isoforms was observed in fish from polluted areas, and these results paralleled data on PCBs and PAHs tissue concentrations. Further, cyp1 isoforms showed clear sex-related differences, with higher mRNA expression in male fish than in females. Principal component analysis revealed a relationship between cyp1 isoforms, ppar-α, β, PCBs and PAHs and these interactions may suggest a crosstalk

    The Carolina Sandhills is a physiographic region of the Atlantic Coastal Plain province in the southeastern United States. In Chesterfield County (South Carolina), the surficial sand of this region is the Pinehurst Formation, which is interpreted as eolian sand derived from the underlying Cretaceous Middendorf Formation. This sand has yielded three clusters of optically stimulated luminescence ages: (1) 75 to 37 thousand years ago (ka), coincident with growth of the Laurentide Ice Sheet; (2) 28 to 18 ka, coincident with the last glacial maximum (LGM); and (3) 12 to 6 ka, mostly coincident with the Younger Dryas through final collapse of the Laurentide Ice Sheet. Relict dune morphologies are consistent with winds from the west or northwest, coincident with modern and inferred LGM January wind directions. Sand sheets are more common than dunes because of effects of coarse grain size (mean range: 0.35–0.59 mm) and vegetation. The coarse grain size would have required LGM wind velocities of at least 4–6 m/sec, accounting for effects of colder air temperatures on eolian sand transport. The eolian interpretation of the Carolina Sandhills is consistent with other evidence for eolian activity in the southeastern United States during the last glaciation.

    Little is known about the drivers of two-month sputum smear non-conversion in the South African context. Our study sought to determine these factors in new sputum smear positive tuberculosis (TB) patients in South Africa’s Free State Province. A retrospective record review was conducted for all TB patients on treatment between 2003 and 2009. Two-month sputum smear non-conversion was defined by a positive sputum smear result. Data was subjected to univariate, bivariate and regression analyses. Generalized linear regression models were used to estimate the risk for two-month sputum smear non-conversion. Age, pre-treatment sputum smear grading, HIV status and TB disease classification influenced two-month sputum smear non-conversion. Significant associations were thus established between health systems, microbiological, clinical and demographic factors, and two-month sputum smear non-conversion. This study provides program managers with evidence to support the development of more tailored TB care. PMID:28299125

    Dragonfly eye beads are considered to be the earliest types of glass objects in China, and in the past have been considered as evidence of culture interaction or trade between West and East Asia. In this article, synchrotron radiation microcomputed tomography and μ-probe energy dispersive X-ray fluorescence were used to determine the chemical composition, microstructure, and manufacturing technology of four dragonfly eye beads, excavated from a Chu tomb at the Shenmingpu site, Henan Province, China, dated stylistically to the Middle and Late Warring State Period (475 BC-221 BC). First, a nondestructive method was used to differentiate the material types including faience (glazed quartz), frit, glazed pottery (clay ceramic), and glass. Three beads were identified as faience and one bead as glazed pottery. The glaze recipe includes quartz, saltpeter, plant ash, and various copper, and is classified as belonging to the K2O-CaO-SiO2 glass system, which indicates that these beads were not imported from the West. Based on computed tomography slices, the manufacturing technology of the faience eye beads appears to include the use of an inner core, molding technology, and the direct application glazing method. These manufacturing features are consistent with the techniques used in China during this same time period for bronze mold-casting, proto-porcelain, and glass.

  12. Climatic impact on isovolumetric weathering of a coarse-grained schist in the northern Piedmont Province of the central Atlantic states

    The possible impact of periglacial climates on the rate of chemical weathering of a coarse-grained plagioclase-muscovite-quartz schist has been determined for a small watershed near Baltimore, Maryland. The isovolumetric chemical weathering model formulated from the geochemical mass balance study of the watershed shows that the weathering front advances at a velocity of 9.1 m/m.y., if the modern environmental parameters remain the same back through time. However, recent surficial geological mapping demonstrates that periglacial climates have impacted the area. Such an impact significantly affects two key chemical weathering parameters, the concentration of CO2 in the soil and groundwater moving past the weathering front. Depending upon the assumptions used in the model, the rate of saprolitization varies from 2.2 to 5.3 m/m.y. The possible impact of periglacial processes suggested by the chemical weathering rates indicates a need to reconsider theories of landscape evolution as they apply to the northern Piedmont Province of the mid-Atlantic states. I suggest that from the Late Miocene to the present that the major rivers have become incised in their present locations; this incision has enhanced groundwater circulation and chemical weathering such that crystalline rocks beneath interfluvial areas remain mantled by saprolite; and the saprolite mantle has been partially stripped as periglacial conditions alternate with humid-temperate conditions. ?? 1993.

    Rodents form a vital component of Free State ecosystems and monitoring them may be a relatively quick and inexpensive method of indicating healthy or unhealthy ecosystem functioning. Using removal trapping, we have studied rodent seasonal abundance, species richness, Shannon diversity, and evenness of rodents in four habitats in the Tussen-die-Riviere Nature Reserve, inspected the most successful sampling method for these habitats, and report on their community structure and how it is related to an Ecological Index (≅ EI value of grassland). Both species richness and Shannon diversity increased significantly with EI value. The indicator species Mastomys coucha occurred at all plots, but contributed the largest proportion of the total captures (ca. 80%) at the plot with lowest EI value. Other results important for small mammal monitoring and collecting are that trap success and species richness was highest in autumn. This study also confirms that four days and nights continuous trapping is essential for the effective sampling of rodent communities in Free State grasslands. Our results partially support expectations that the number of specialist species increases with succession, M. coucha dominance acts as an indicator of habitat disturbance, rodent species richness conforms to Tilman's hump-shaped curve model, and adds to a baseline of diversity indices in a variety of grassland habitats.

    thickness of the unsaturated zone. Aggradation in basinal troughs may either decrease or increase the thickness of the unsaturated zone. Aggradation in basins that causes the ground-water discharge level to rise will tend to decrease the thickness of unsaturated zone in the adjacent uplands; aggradation in basins where the ground-water discharge level remains the same or is lowered will increase the unsaturated thickness of basin fill.Records show that, throughout late Cenozoic time in the Basin and Range province, continued vertical crustal movements have tended to maintain mountain ranges and closed basins, whereas aggradation of the basins and erosion of the mountain ranges have tended to decrease the topographic relief. Maximum rates of denudation for small basins in areas climatically similar to the Basin and Range province are about 2 meters per 104 years. For sites unaffected by stream incision and scarp retreat, a conservative estimate of erosion affecting long-term changes in depth of burial would appear to be 2 meters per 104 years, or, equal to the long-term rate of vertical crustal movement where greater than 2 meters per 104 years. The response of the ground-water conditions to climatic and geomorphically induced boundary conditions is significant from the points of: (1) The potential maximum change in the ground-water flow system; (2) the time of response of the ground-water system; and (3) the present state of the ground-water system as a result of past changes. Effects of longterm climatic and tectonic changes on hydrologic and geomorphic conditions differ from area to area, and rates of change of geomorphic and hydrologic conditions may vary significantly. Therefore, sitespecific studies need to be made to assess the long-term integrity of deep, mined repositories.

    This report presents summary papers of work conducted between 2002 and 2007 under a 5-year project effort funded by the U.S. Geological Survey Mineral Resources Program, formerly entitled 'Tintina Metallogenic Province: Integrated Studies on Geologic Framework, Mineral Resources, and Environmental Signatures.' As the project progressed, the informal title changed from 'Tintina Metallogenic Province' project to 'Tintina Gold Province' project, the latter being more closely aligned with the terminology used by the mineral industry. As Goldfarb and others explain in the first chapter of this report, the Tintina Gold Province is a convenient term used by the mineral exploration community for a 'region of very varied geology, gold deposit types, and resource potential'. The Tintina Gold Province encompasses roughly 150,000 square kilometers, bounded by the Kaltag-Tintina fault system on the north and the Farewell-Denali fault system on the south. It extends westward in a broad arc, some 200 km wide, from northernmost British Columbia, through the Yukon, through southeastern and central Alaska, to southwestern Alaska. The climate is subarctic and, in Alaska, includes major physiographic delineations and ecoregions such as the Yukon-Tanana Upland, Tanana-Kuskokwim Lowlands, Yukon River Lowlands, and the Kuskokwim Mountains. Although the Tintina Gold Province is historically important for some of the very first placer and lode gold discoveries in northern North America, it has recently seen resurgence in mineral exploration, development, and mining activity. This resurgence is due to both new discoveries (for example, Pogo and Donlin Creek) and to the application of modern extraction methods to previously known, but economically restrictive, low-grade, bulk-tonnage gold resources (for example, Fort Knox, Clear Creek, and Scheelite Dome). In addition, the Tintina Gold Province hosts numerous other mineral deposit types, possessing both high and low sulfide content, which

    This paper reports the analysis results of 11 decorated silicate beads samples excavated from Ma Jia-yuan Warring State Cemetery, Gan Su Province with the portable X-ray fluorescence spectrometer, laser Raman spectrometer and X-ray diffraction spectrometer. It is includes 3 types among these samples on the basis of their chemical composition, NaO-CaO-SiO2, PbO-BaO-SiO2 glass system, and glassy faience. The blue part of the NaO-CaO-SiO2 glass sample was colored by Co2+, and Sb2O5 was discovered as opacifier. The results of Laser Raman analysis shows in some circle beads exits Chinese blue and Chinese purple. Combined with the existing research results the early cultural factors and technical exchange reflected from these samples are discussed. It shows that the material and craftsmanship of the beads contained Chinese blue and Chinese purple were affected by Qin Culture. But the composition of the Na-Ca-SiO2 glass eye bead is similar with those excavated from Xin Jiang area. It infers the technology of glass manufacture of the Xi Ron nationality was influenced by the Qin Culture and the grassland nationalities' culture simultaneously. The faience bead composed with the inner core and the outer glassy layer is possible a kind of transitional type between the faience and the real glass. This information offers a new reference for the research of the origin of the glass technology in the ancient China.

    HIV serostatus disclosure to community members has been shown to have potential public and personal health benefits. This study examined the impact of bonding and bridging social capital (i.e. close and distant ties) on public disclosure and described the complex relationship between bonding and bridging social capital in the context of serostatus disclosure among AIDS patients enrolled in South Africa's public sector antiretroviral treatment (ART) program. Data were collected from a cohort of patients enrolled in the public sector ART program in the Free State province of South Africa. Semi-structured, face-to-face interviews were conducted with a random sample of 268 patients at three points in time (<6 months of ART, 6-12 months of ART, and 18-24 of months ART). The relationship between bonding and bridging social capital and the impact of different forms of social capital on public disclosure were determined using a fully cross-lagged regression model. The impact of bonding social capital (treatment and emotional buddy) on public disclosure was positive and invariant across time. The results from the cross-lagged regression indicated that bridging social capital (community health worker and support group) only encouraged public disclosure in the second year of treatment. At the start of treatment, bivariate analysis showed a strong negative association between bonding and bridging social capital, which diminished at follow-up and eventually disappeared in the second year of treatment. This study identified bonding social capital as a leverage to maximize potential benefits and minimize potential risks in order to shift the balance toward consistent public disclosure. Furthermore, the importance of bridging social capital initiatives is demonstrated, especially for the most vulnerable patients, those who cannot capitalize their bonding social capital by disclosing their HIV serostatus to family and friends at the start of treatment.

    Low-temperature cycling of paleomagnetic specimens across the Verwey transition is a common technique used to preferentially remove remanence associated with multi-domain magnetite grains. This low-temperature demagnetization (LTD) step is gaining increasing use in both paleodirectional and paleointensity protocols making it imperative to understand the mechanism, efficiency and possible limitations of LTD. A recently developed cryogenic probe used in conjunction with a superconducting rock magnetometer at the Institute for Rock Magnetism allows for three-axis measurements to be made during cycling to and from low-temperatures in a low-field environment. In this study, we targeted a suite of well-characterized samples from the Umkondo Large Igneous Province of Botswana that displayed large (~50%) demagnetization of the natural remanence after cooling to 77 K including some samples that underwent large directional changes. Three-axis data were continuously collected during low-temperature cycling experiments on both natural remanence and lab-induced anhysteretic remanent magnetization (pARM). Experiments were designed with orthogonal pARMs to observe the behavior and efficiency of demagnetization of remanence carried by low coercivity (multi-domain grains). These experiments revealed high efficiency of demagnetization (>95%) of a pARM imparted to low coercivity grains (AF fields of 0 to 5 mT) with a return to the direction of a pARM imparted to higher coercivity grains (AF fields of 5 to 200 mT). The data also demonstrate that low-temperature demagnetization of such a pARM upon cooling is dominated by changes prior to the Verwey transition or the isotropic point. These results suggests that it is changes in magnetocrystalline anisotropy (K1) at temperatures above the isotropic point that are responsible for the majority of low-temperature demagnetization of multidomain magnetite grains. The low-temperature probe is available for community use at the Institute for

    From the community profiles conducted by nursing students in Mangaung, the following observation was prevalent: an increase in the prevalence of teenage pregnancy together with a high prevalence of HIV infection was demonstrated. The relationship between young people's reproductive behaviour and the prevalence of HIV is well documented. To address this problem, a community -based education programme is required. Developing a successful community-based educational programme that addresses the needs of youth requires that such a programme be based on the needs of such a group. The research question is applicable: How do youth in Mangaung in the Free State province in South Africa perceive their reproductive health needs and their reproductive health behaviour? The aim of this article is to explore and describe the reproductive health needs and the reproductive health behaviour of the youth in Mangaung. A quantitative research design that is descriptive and explorative in nature was conducted. The reproductive health needs and the reproductive health behaviour of the youth were collected by means of a structured questionnaire with open-ended and closed questions. A purposive non - probability sampling method was utilized and (n=250) drawn from the youth. The justification of the sample was further enhanced by collecting data from youth aged 13-25 at three high schools in Mangaung and at the health centre of MUCPP. Qualitative data obtained from open-ended questionnaires was coded and analyzed by using Tech's (1990) content analysis approach. A descriptive statistical analysis was performed on the quantitative data from closed questions. A descriptive analysis of the participant's ages and their perceived reproductive health needs and reproductive health behaviour was done. The mean age of the participants was 18.6, which could be because all the respondents were of school- going age. The results indicated that the youth received insufficient reproductive health

    A conceptual model was developed for the Arches Province that integrates geologic and hydrologic information on the Eau Claire and Mt. Simon formations into a geocellular model. The conceptual model describes the geologic setting, stratigraphy, geologic structures, hydrologic features, and distribution of key hydraulic parameters. The conceptual model is focused on the Mt. Simon sandstone and Eau Claire formations. The geocellular model depicts the parameters and conditions in a numerical array that may be imported into the numerical simulations of carbon dioxide (CO2) storage. Geophysical well logs, rock samples, drilling logs, geotechnical test results, and reservoir tests were evaluated for a 500,000 km2 study area centered on the Arches Province. The geologic and hydraulic data were integrated into a three-dimensional (3D) grid of porosity and permeability, which are key parameters regarding fluid flow and pressure buildup due to CO2 injection. Permeability data were corrected in locations where reservoir tests have been performed in Mt. Simon injection wells. The final geocellular model covers an area of 600 km by 600 km centered on the Arches Province. The geocellular model includes a total of 24,500,000 cells representing estimated porosity and permeability distribution. CO2 injection scenarios were developed for on-site and regional injection fields at rates of 70 to 140 million metric tons per year.

    Phosphorus from natural and human sources is likely to be discharged from groundwater to streams in certain geochemical environments. Water-quality data collected from 1991 through 2007 in paired networks of groundwater and streams in different hydrogeologic and land-use settings of the Piedmont, Blue Ridge, and Valley and Ridge Physiographic Provinces in the eastern United States were compiled and analyzed to evaluate the sources, fate, and transport of phosphorus. The median concentrations of phosphate in groundwater from the crystalline and siliciclastic bedrock settings (0.017 and 0.020 milligrams per liter, respectively) generally were greater than the median for the carbonate setting (less than 0.01 milligrams per liter). In contrast, the median concentrations of dissolved phosphate in stream base flow from the crystalline and siliciclastic bedrock settings (0.010 and 0.014 milligrams per liter, respectively) were less than the median concentration for base-flow samples from the carbonate setting (0.020 milligrams per liter). Concentrations of phosphorus in many of the stream base-flow and groundwater samples exceeded ecological criteria for streams in the region. Mineral dissolution was identified as the dominant source of phosphorus in the groundwater and stream base flow draining crystalline or siliciclastic bedrock in the study area. Low concentrations of dissolved phosphorus in groundwater from carbonate bedrock result from the precipitation of minerals and (or) from sorption to mineral surfaces along groundwater flow paths. Phosphorus concentrations are commonly elevated in stream base flow in areas underlain by carbonate bedrock, however, presumably derived from in-stream sources or from upland anthropogenic sources and transported along short, shallow groundwater flow paths. Dissolved phosphate concentrations in groundwater were correlated positively with concentrations of silica and sodium, and negatively with alkalinity and concentrations of calcium

    Six regions in the Basin and Range province, ranging in size from 21,600 to 80,000 square kilometers, were evaluated to identify prospective hydrogeologic environments for isolation of high-level radioactive waste. Prospective hydrogeologic environments were evaluated on the basis of the surface distribution of potential host rocks, late Cenozoic tectonic activity, hydrogeologic characteristics, and mineral and energy resources. These regions were selected as prospective for this study from a screening of the Basin and Range province. The six regions have certain characteristics that appear favorable for isolation of radioactive waste. The scant precipitation and great potential for water loss by evaporation and transpiration results in little surface runoff and ground-water recharge. This, combined with other hydrogeologic factors, results in areas within the regions that have thick unsaturated zones and long ground-water flow paths and traveltimes. Potential host media in the unsaturated zone include crystalline rocks, volcanic rocks, and basin fill. Potential host media in the saturated zone are predominantly crystalline igneous rocks but also include argillaceous rocks, evaporitic rocks, intracaldera tuffs, and laharic breccias.

    INTRTODUCTION: A shortage of health workers is a major problem for Nigeria, especially in rural areas where more than 70% of the population live. At the primary care level, trained community health officers provide services normally reserved for doctors or medical specialists. The community health officers must therefore be supported and motivated to provide effective quality healthcare services. This study aimed to determine factors that will attract and retain rural and urban health workers to rural Nigerian communities, and to examine differences between the two groups. A cross-sectional survey measured health workers' work experience, satisfaction with, and reasons for undertaking their current work; as well as reasons for leaving a work location. Data were also gathered on factors that attract health workers to rural settings and also retain them. RESULTS; Rural health workers were generally more likely to work in rural settings (62.5%) than their urban counterparts (16.5%). Major rural motivators for both groups included: assurances of better working conditions; effective and efficient support systems; opportunities for career development; financial incentives; better living conditions and family support systems. The main de-motivator was poor job satisfaction resulting from inadequate infrastructure. Rural health workers were particularly dissatisfied with career advancement opportunities. More urban than rural health workers expressed a wish to leave their current job due to poor job satisfaction resulting from poor working and living conditions and the lack of career advancement opportunities. Motivational factors for attraction to and retention in rural employment were similar for both groups although there were subtle differences. Addressing rural health manpower shortages will require the development of a comprehensive, evidence-based rural health manpower improvement strategy that incorporates a coordinated intersectoral approach, involving partnership with a range of stakeholders in rural health development.

    This paper explores the impacts of oil spill on the physical environment with particular attention paid to the NNPC/PPMC pipeline system. It focuses on the environmental impacts of oil pollution in Nigeria, and discusses the increasing environmental contradictions of the area, and its influence on global warming. Nigeria's economy is highly dependent on earnings from the oil sector, which provides 20% of GDP, 95% of foreign exchange earnings, and about 65% of budgetary revenues. Since the discovery of oil in Nigeria in 1956, the country has been suffering the negative environmental consequences of oil exploration and exploitation. Between 1976 and 1996 a total of 4647 incidents resulted in the spill of approximately 2,369,470 barrels of oil into the environment. The study traces the effects of the oil spillage on the environment to determine whether oil spill is a major factor responsible for environmental pollution. By the use of remotely sensed data and other ancillary data, the major causes of oil spill in the region were identified; the presence of total petroleum hydrocarbon (TPH) in the environment, and it also determined the environmental impacts on land and water. Field observation and laboratory analysis of soil and water were used. Gas chromatography was used to determine the TPH concentration in soil extract and water extracts. Liquid-liquid extraction method was used for water and spectro-radiometer which is a very efficient process commonly used to determine spectral signature of various soil, water and plant samples obtained from the study area. Based largely on the GIS analysis, the findings showed that the main cause of oil spill is vandalism along the pipeline right of way; Vandalism which is an act of sabotage had the highest percentage compared to equipment failure, accident from oil tankers and accidental discharge during pipeline repairs. TPH were present at the site with soil samples having the high values, and the environmental impact on soil and water is due to poor resource management and control. Satellite imagery (Ikonos and Landsat series) helped in monitoring oil spill by providing the spill position. The petroleum industries should work with government agencies, universities and research centers to prevent oil spill incidents. Keywords: Environment, Pollution, GIS, TPH, Analysis, Vandalism.

    The activity concentration of natural radionuclides in soil samples from industrial dumpsites in Sango-Ota were determined using gamma-ray spectrometry with NaI(Tl) detector. The mean activity concentration of 226Ra, 232Th and 40K was 3.0 ± 1.2, 33.3 ± 9.8 and 122.1 ± 20.6 Bqkg−1, respectively. Radium equivalent activities were calculated to assess the hazards arising from the use of the soil sample in agriculture. All the calculated values were lower than the world average. The mean concentration of heavy metals in the soil samples were 33.6, 2.9, 3.8, 2.7, 48.9, 1,5, 34.5 and 0.8 mg l-1 for Cu, Mg, Ca, P, Fe, Pb, Zn and Cd, respectively. The concentrations of Cd, Cu and Pb were higher than the natural permissible range in soil. Therefore, the government should discourage the use of the soil around dumpsites for planting because of the presence of heavy metals in the sites. PMID:24872608

    Phthalate esters (PEs) are one of the environmentally active organic pollutants capable of causing endocrine disruption. The levels of PE congeners were determined in the influent and effluent from Covenant Oxidation Pond (COP) and Ikeja Wastewater Treatment Plant (IWWTP). Standard methods were adopted for determining the physical and chemical parameters of the water samples. The water samples for PE congener's determination were collected, acidified and stored at 4 °C prior to liquid-liquid extraction and analysis by gas chromatograph. The possible health risk associated with the usage of effluent-polluted river water was also investigated. The pH and temperature ranges were within the Federal Ministry of Environment (FME) 2001 guideline limits while the dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were above the limits. The IWWTP performed better at removing PEs at 54% compared to 43.3% on average at COP. The health risk of individual PE congener showed no non-cancer effects (HQ) as the values varied from 5.01E-05 (DAP) to 1.52E-02 (DEHP) for adults and 1.17E-04 (DAP) to 3.76E-03 (DBP) for children at COP, while at IWWTP, it ranged from 8.06E-05 (DIBP) to 1.09E-02 (DEHP) for adults and 5.68E-04 (MMP) to 2.54E-02 (DEHP) for children. Notwithstanding, the usage of effluent-polluted river water by local communities downstream may result in carcinogenic effects due to the cumulative effects of the PE congeners as the values obtained for adults and children for the ingestion and dermal routes for the two waste process streams ranged from 4.67E-06 (IWWTP) to 6.22E-05 (IWWTP) and 2.18E-05 (IWWTP) to 7.18E-05 (COP), respectively.

    According to State Council regulations, Sichuan Province has begun charging entrepreneurial units fees for discharging waste water, waste gas and waste residue in excess of state standards, and using the money to treat environmental pollution. Results have been notable. Charging fees for discharging wastes is a major economic measure which the state has adopted to promote environmental protection. So far over 120 cities and counties in the province have adopted this measure. From April 1980 to the end of 1982, the province collected a total of 68 million yuan to fund 1,200 waste treatment projects. As a spinoff of the measure, the enterprises began raising funds on their own to treat pollution. Before 1979, the province spent an average of 3 million yuan annually on treatment of pollution. Last year the figure reached 28 million yuan. Since effluent fees came into effect, Leshan City has invested more money on more pollution-treatment projects every year. Chengdu City invested 14 million yuan in 1982 on 514 projects, completing 292 projects the very same year. The completed projects treat 25,000 tons of effluent a day. Waste water containing disease germs discharged from the army-system hospitals in the province is by and large treated. Effluent fees have spurred the enterprises to strengthen management, conserve and comprehensively utilize resources and energy, thus improving the economic results of the enterprises.

  10. Nematodes from Swainson's spurfowl Pternistis swainsonii and an Orange River francolin Scleroptila levaillantoides in Free State Province, South Africa, with a description of Tetrameres swainsonii n. sp. (Nematoda: Tetrameridae).

    Five Swainson's spurfowl collected in Free State Province, South Africa, were examined for helminth parasites, and the nematodes Acuaria gruveli, Cyrnea parroti, Gongylonema congolense, Subulura dentigera, Subulura suctoria and a new Tetrameres species were recovered. Their respective prevalence was 100, 20, 80, 20, 20 and 20%. These nematodes are all new parasite records for Swainson's spurfowl, and Acuaria gruveli constitutes a new geographical record as well. A single specimen of Cyrnea eurycerca was found in an Orange River francolin, representing a new host and geographical record for this parasite. The new species, for which the name Tetrameres swainsonii is proposed, can be differentiated from its congeners by a combination of the following characters of males: two rows of body spines, a single spicule which is 1152-1392 microm long, and eight pairs of caudal spines arranged in two ventral and two lateral rows of four spines each. The single female has the globular shape typical of the genus.

  11. Hydrogeologic terranes and potential yield of water to wells in the Valley and Ridge Physiographic Province in the eastern and southeastern United States

    The Valley and Ridge Physiographic Province is underlain by deformed sedimentary rock of Paleozoic age including dolomite, limestone, shale, and sandstone. Regolith (soil, sediment, and weathered rock) covers the Paleozoic rock throughout most of the province. Local differences in lithology, structure, and weathering can result in four orders of magnitude variation in the water-yielding properties of the geologic units that underlie the area. Selected rock types, however, can account for a substantial part of this variation because of the unique way in which these dense, consolidated sedimentary rock types deform and weather to produce secondary openings.On the basis of relations among rock type, water-yielding openings, and water-yielding properties (as indicated by specific capacity), the regolith and consolidated rock were classified and mapped as five hydrogeologic terranes alluvium, dolomite, limestone, argillaceous carbonate rock, and siliciclastic rock. The hydrogeologic terranes are named after the predominant outcrop lithology within them. The western toe of the Blue Ridge Mountains is classified as a subdivision of the dolomite hydrogeologic terrane that may produce yields of water in excess of 1,000 gallons per minute (gal/min) to public and industrial supply wells. Specific-capacity data for homogeneous data sets, which consist of all wells that have the same characteristics in regard to casing diameter, primary use of the water, and topographic setting, revealed significant differences in water-yielding properties among the five hydrogeologic terranes. According to results of Tukey statistical tests at a probability (alpha level) of 0.05, 8 out of 10 pairs of hydrogeologic terranes (for example, alluvium/limestone) had significantly different median specific-capacity values. The median value for public and industrial supply wells in the western toe is three times greater than the value for comparable wells in the dolomite hydrogeologic terrane

    This study shows how data emanating from very different sources can be integrated using modern statistical and spatially explicit techniques in order to gain insights into ecological processes leading to differentiation between closely related taxa. We test ecological radiation in the striped mouse (Rhabdomys sp.) using a niche modeling approach to compare habitat characteristics of its three mitochondrial lineages, which we show to co-occur in a South African province. Here, we describe and make predictions on the distribution and potential niches of these lineages and locate contact zones between them. Our study involved field investigations, genotyping, GIS and multivariate statistics analyses. We used Maxent, an approach allowing us to produce suitability maps and predict potential contact zones. Our results strongly suggest that the three lineages could have different environmental niches which may explain their co-occurrence in some areas. Further, these results might give credence to the hypothesis of ecological radiation within the genus, which could be further tested in contact zones highlighted in our study.

    We completed a field sampling transect across the northern Sierra Madre Occidental silicic large igneous province (SMO) in December 2013. Here we present the first stratigraphic, petrological, and geochemical data from the transect between Hidalgo del Parral and Guadalupe y Calvo, Chihuahua, Mexico. This is the first new transect across the SMO in 25 years and the only one between existing NE - SW transects at Chihuahua - Hermosillo and Durango - Mazatlan. The 245 km-long transect along Mexican Highway 24 crosses the boundary between the extended (Basin and Range) and non-extended (Sierra Madre Occidental plateau) parts of the SMO, and allows sampling of previously undescribed Oligocene (?) - early Miocene (?) rhyolitic ignimbrites and lavas, and occasional post-rhyolite, Miocene (?) SCORBA basaltic andesite lavas. 54 samples of rhyolitic ignimbrites (40) and lavas (7), and basaltic andesite lavas (7) were sampled along the transect, including 8 canyon sections with more than one unit. The ignimbrites are overwhelming rhyodacitic (plagioclase and hornblende or biotite phyric) or rhyolitic (quartz (+/- sanidine) in additon to plagioclase and hornblende or biotite phyric) and sparsely to highly phyric. Preliminary petrographic (phenocryst abundances) and geochemical (major and trace element) will be presented and compared to existing data from elsewhere in the SMO. Future work will include U-Pb zircon dating and whole rock and in-zircon radiogenic isotopes analyses.

    Recent studies have indicated that the support of close relatives is fundamental in coping with HIV/AIDS and in accessing the emotional and material support necessary for sustained adherence to treatment. Because disclosure to family members is imperative to ensure their support, identifying tools or resources that can minimize the possible risks and maximize the potential benefits of disclosure should be useful in improving the lives of people living with HIV/AIDS. Where health systems require strengthening, engaging the community in HIV/AIDS care could potentially create an environment that encourages disclosure to family members. This study investigated the impact of community support initiatives (community health workers and treatment support groups), patient characteristics (age, gender, and education), and time since first diagnosis on the disclosure of serostatus to family members by a sample of 268 public-sector antiretroviral treatment patients in a province of South Africa between August 2004 and July 2007. Whereas gender, age, and education only weakly influenced disclosure, there was a strong and stable positive association between community support and disclosure to family members. The immediate and long-term impact of community support on the disclosure by seropositive patients to family members indicates that initiatives such as community health workers and HIV support groups run by people living with HIV/AIDS should be strengthened, especially for those patients who cannot disclose their status to immediate family and close friends.

  17. Contemporary tectonic deformation of the Basin and Range province, western United States: 10 years of observation with the Global Positioning System

    Hammond, W.C.; Thatcher, W.

    2004-01-01

    We have estimated patterns and rates of crustal movement across 800 km of the Basin and Range at ???39?? north latitude with Global Positioning System surveys in 1992, 1996, 1998, and 2002. The total rate of motion tangent to the small circle around the Pacific-North America pole of rotation is 10.4 ?? 1.0 mm/yr, and motion normal to this small circle is 3.9 ?? 0.9 mm/yr compared to the east end of our network. On the Colorado Plateau the east end of our network moves by ???1-2 mm/yr westerly with respect to North America. Transitions in strain rates delimit six major tectonic domains within the province. These deformation zones coincide with areas of modern seismicity and are, from east to west, (1) east-west extension in the Wasatch Fault zone, (2) low rate east-west extension centered near the Nevada-Utah border, (3) low rate east-west contraction between 114.7??W and 117.9??W, (4) extension normal to and strike-slip motion across the N10??E striking Central Nevada Seismic Zone, (5) right lateral simple shear oriented N13??W inside the Walker Lane Belt, and (6) shear plus extension near the Sierra Nevada frontal faults. Concentration of shear and dilatational deformation across the three westernmost zones suggests that the Walker Lane Belt lithosphere is rheologically weak. However, we show that linear gradients in viscosity and gravitational potential energy can also effectively concentrate deformation. In the Basin and Range, gradients in gravitational potential are spatially anticorrelated with dilatational strain rates, consistent with the presence of horizontal variations in viscosity of the lithosphere.

  18. Tectonics and metallogenic provinces

    USGS Publications Warehouse

    Guild, P.W.

    1983-01-01

    Various theories have been advanced to explain the well-known uneven distribution of metals and ore-deposit types in space and time. Primordial differences in the mantle, preferential concentration of elements in the crust, the prevalence of ore-forming processes at certain times and (or) places, and combinations of one or several of these factors have all been called upon to account for the "metallogenic provinces," which can be defined loosely as regions containing similar deposits of one or a group of metals or minerals. Because many, perhaps most, provinces have complex, multistage origins, the relative importance of inheritance vs. process is still controversial. In recent years the geographic relationship of many geologically young provinces to present-day plate-tectonic positions (accreting or consuming margins, intraplate structures, etc.) has been widely recognized, and the presumption is strong that older provinces had similar relationships to former plates. As most ore deposits resulted from a favorable conjunction of geological processes that are no longer operative, elucidation of their genesis requires reconstruction of the geologic history of the province, with particular emphasis on events coeval with mineralization. Tectonic analysis is an important aspect of this reconstruction; data from orbiting satellites have contributed greatly to this analysis, as the voluminous literature of the past decade testifies. Both the synoptic view of large areas and the ability to emphasize faint contrasts have revealed linear, curvilinear, and circular features not previously recognized from field studies. Some of these undoubtedly reflect basement structures that have contributed to the development, or limit the extent, of metallogenic provinces. Their recognition and delineation will be increasingly valuable to the assessment of resources available and as guides to exploration for the ores needed by future generations. ?? 1983.

    The geologic provinces of Oklahoma are mainly the product of tectonics and attendant sedimentation of Pennsylvanian age. Most boundaries are structural; thus, the provinces map is a generalized tectonic map. Permian and post-Paleozoic strata tend to mask those structures, but most of those strata have been removed by erosion, except in the Anadarko Basin and the Wichita Uplift provinces. The location of most of Oklahoma`s oil and gas resources are either influenced by, or are the direct result of Pennsylvanian tectonics and sedimentation patterns. Therefore, the present study also defines provinces in the subsurface on the basis of geological criteria. The authors have attempted to use the originally published names for the recognized provinces. However, we have also used the most geologically correct names, i.e., Nemaha Uplift, Nemaha Fault Zone, and Central Oklahoma Fault, in lieu of Nemaha {open_quotes}Ridge.{close_quotes} Oklahoma is separated into five major uplifts and five major basins. The Gulf Coastal Plain is not included in this study because it is a veneer of Cretaceous cover that masks significant structures. Faults are the most common boundary element. Although their precise age commonly is known only approximately, their geographic location is less controversial, except in detail. Stratigraphic/structural boundaries are based on less precise geological information. The major example of a surface stratigraphic/structural boundary is the southwestern limit of the Ozark Uplift in eastern Oklahoma. Stratigraphic/structural boundaries in the subsurface are commonly based on structural or isopachous contours from well or geophysical data, or on a structural trend, as well as the experience of the authors. Basement structure is preferred. An example is the boundary that separates the Marietta Basin from adjacent geologic elements.

    Associations between vitamin D deficiency and a broad variety of independent diseases, including several bone diseases, various types of cancer, autoimmune diseases, hypertension, and cardiovascular disease, have been suggested. It is therefore important to detect and treat vitamin D deficiency in high-risk groups. Because patients with albinism (PWA) practice a policy of strict sun avoidance, they may be at risk for low levels of vitamin D. This study was conducted in patients attending dermatology clinics in the Free State, South Africa, to determine sun avoidance behavior in the patient population and to compare 25-hydroxyvitamin D (25[OH]D) levels in PWA with those in normally pigmented Black patients attending the same clinics. Serum 25(OH)D levels were assessed in 50 PWA and 50 normally pigmented Black control subjects. Questionnaires on sun exposure avoidance behaviors were administered to all participants. The present study showed no statistically significant difference in median 25(OH)D levels between PWA and controls with normally pigmented Black skin. Rather, the study found a tendency for controls to have lower 25(OH)D levels. A total of 53% (n = 53) of all study participants (PWA and controls) had a 25(OH)D level of <20 ng/ml; thus most participants were deficient in vitamin D. Most of the PWA who participated in the study did not adhere to strict sun avoidance behavior. People with albinism attending dermatology clinics in the Free State, South Africa, need not be viewed as specifically at risk for low vitamin D levels. © 2015 The International Society of Dermatology.

    Microdeletions of chromosome 22 are common and have a prevalence of at least 1/4 000. Cardiac abnormalities, abnormal facial features and palatal abnormalities are frequently present in these patients. To describe the cardiac lesions and selected measurable facial features in children from the Free State and Northern Cape presenting at the Cardiology Unit of the Universitas Academic Hospital complex in Bloemfontein. This was a prospective study in which patients with abnormal facial characteristics were tested using a fluorescence in situ hybridisation (FISH) probe for the 22q11.2 microdeletion. Forty children tested positive for the microdeletion. All patients underwent an echocardiogram and where possible, facial anthropometric measurements were performed. The median age at diagnosis was 3.6 years (range 0.04 years, i.e. 2 weeks to 16.2 years). Tetralogy with or without pulmonary atresia was diagnosed in 43% (n = 17) of the children and truncus arteriosus in 20% (n = 8). A rightsided aortic arch was present in 43% (n = 17) of the patients. Mid-facial height was slightly longer (median = 1.0; range -0.5 to 3.3) and width narrower (median = -1.4; range -2.2 to 0.1) than normal. Ear height and width were notably small compared to normal, with median -scores = -3.3 (range -4.8 to -2.6) and = -2.4 (range -3.4 to -1.4), respectively. Microdeletions of chromosome 22q11 are present in children from the Free State and Northern Cape. Conotruncal cyanotic heart lesions, especially tetralogy with or without pulmonary atresia and truncus arteriosus were the most frequent congenital cardiac diagnoses. A right-sided aortic arch was also commonly present in these children. Facial features varied and small ears were the most noteworthy anthropometric feature. A right-sided aortic arch with or without a congenital cardiac lesion, a long, narrow mid-face and small ears should alert the physician to the possibility of a microdeletion on the long arm of chromosome 22.

    The Atlantic Forest represents one of the global priority eco-regions for biodiversity conservation. In Argentina, this is represented by the Paranense Forest, which occupies much of the Misiones Province. In this paper, an updated list of land mollusks from Misiones Province is presented, and its species richness was evaluated comparing protected and unprotected areas. For this, we reviewed La Plata Museum Mollusk Collection, updated the literature review, and developed some field work between 2009 and 2010. For the areographic work, a grid (50 x 50 km) was applied to a Misiones province map. In this region, large areas of native vegetation constituting the Paranaense Forest still persist, and include protected areas such as the Iguazú National Park and Puerto Peninsula Provincial Park. These areas have been the most explored at the malacological level (both terrestrial and aquatic environments), a fact that is consistent with the greater number of records found, which may also be the explanation for the highest number of species recorded in the region. A database containing 497 records was compiled. The number of species occurring in this Province was increased from 28 to 56; 11 of which were exotic species. A total of 38 of the species occurred in protected areas and 53 in unprotected areas; and 25 species were micro-mollusks. Orthalicidae was the family with the highest species number (10) and the widest distribution, occupying 16/20 sampling units. Megalobulimus was the genus found in a greater number of sampling units (14/20). The highest values of specific richness of land gastropods were found in Northern Misiones (R=32). This richness was similar to that previously reported for the Tucumán Province, although species occurring in both provinces were mostly different. The richness in Misiones Province border areas, as the Republic of Paraguay and the state of Santa Catarina (Brazil), was about twice that found in the province. The present study showed the

    A crust-upper mantle configuration is proposed for the Tharsis province of Mars which is isostatic and satisfies the observed gravity data. The model is that of a low density upper mantle compensating loads at both the surface and crust-mantle boundary. Solutions are found for lithospheric thickness greater than about 300 km, for which the stress differences are less than 750 bars. This model for Tharsis is similar to the compensation mechanism under the Basin and Range province of the western United States. These provinces also compare favorably in the sense that they are both elevated regions of extensional tectonics and extensive volcanism.

    The MISR instrument on NASA's Terra platform has been operating for almost 15 years. Standard products are generated at a spatial resolution of 1.1 km or coarser, but a recently developed method to re-analyze the Level-1B2 data allows the retrieval of biogeophysical products at the native spatial resolution of the instrument (275 m). This development opens new opportunities to better address issues such as the management of agricultural production and food security. South African maize production is of great economic and social importance, not only nationally, but on the global market too, being one of the top ten maize producing countries. Seasonal maize production statistics are currently based on a combination of field measurements and estimates derived from manually digitizing high resolution imagery from the SPOT satellite. The field measurements are collected using the Producer Independent Crop Estimate System (PICES) developed by Crop Estimates Committee of the Department of Agriculture, Forestry and Fisheries. There is a strong desire to improve the quality of these statistics, to generate those earlier, and to automate the process to encompass larger areas. This paper will explore the feasibility of using the MISR-HR spectral and directional products, combined with the finer spatial resolution and the relatively frequent coverage afforded by that instrument, to address these needs. The study area is based in the Free State, South Africa, one of the primary maize growing areas in the country, and took place during the 2012-2013 summer growing season. The significance of the outcomes will be evaluated in the context of the 14+ years of available MISR data.

    Although HIV/AIDS constitute a significant health burden among children in South Africa, testing and counselling of exposed children are inadequate. It is therefore imperative that factors relating to paediatric HCT services offered by health workers are examined. This study was conducted to explore and describe the perceptions and experiences of trained professional nurses regarding HIV counselling and testing among children. We conducted six focus group discussions among trained professional nurses in health facilities in a district in Free State Province, South Africa. All verbatim transcripts were analysed with a thematic approach and emergent codes were applied. Forty-seven trained professional nurses participated in the study and two of them were males. The age of the participants ranges from 38 to 60 years while the median age was 50 years. Most participants in the focus groups explained how HCT occurs during regular health talks and that lay counsellors are doing most of the counselling. While a few participants thought that children should not be bothered with HCT, most of them seek consent from caregivers for HIV test for children. While children whose parents are negative are usually not tested, most children are tested only when they become ill. Identified barriers to HCT among children include refusal of consent, work overload, lack of encouragement, and poor record keeping. Participants recommended improvement of issues relating to community mobilization and increasing trained staff strength for optimal paediatric HCT service delivery. Developing guidance and policies with respect to obtaining consent, recruiting more health providers, and addressing structural issues in the society to reduce stigma and discrimination were identified as key priority issues by majority of the participants. The perspectives of these participants who provide paediatric HCT services offer vital insight which may be useful to inform policy interventions.

    1962-01-01

    As part of a study of the status of investigations and development of ground water in Brazil, made under the auspices of the United States International Cooperation Administration and with the cooperation of the Government of Brazil, the country was divided into seven ground-water provinces. The identification and delineation of the provinces were based on the regional distribution of the dominant geologic units which are known or inferred to have distinctive water-bearing characteristics. Three of the provinces, covering most of the country, are underlain by Precambrian crystalline rocks. Three others coincide in part with four extensive sedimentary basins--the Parnaiba or Maranhfio basin and the contiguous Sao Francisco basin in the northeast and east, the Amazon basin in the north and northwest, and the Paranfi basin in the south and southwest. In addition, the narrow, discontinuous coastal plain is considered as a province. the occurrence of ground water is discussed briefly, and pertinent data are given on the more important aquifers, together with information on some existing wells. Because of the widespread distribution of crystalline rocks of low permeability, it is difficult in many areas to develop large or even adequate ground-water supplies. In general, satisfactory supplies of water are available in most of the rest of the country. Some problems include the relative deficiency of rainfall in the northeast together with the occurrence, in parts of this region, of mineralized water in the crystalline rocks. Also, there is a potential problem of excessive lowering of water levels and interference among wells in the intensively developed area of the city of Sao Paulo.

    Kurdistan Province, with an area of 28,203 square kilometers, is located in a mountainous area in the western part of Iran. From 1967 to 1997, the urban population in the major eight cities of the Kurdistan Province-namely, Baneh, Bijar, Divan Darreh, Saghez, Sanandaj, Ghorveh, Kamyaran, and Marivan-increased from 102,250 to 705,715. The proportion of the population residing in urban areas increased 90 percent during this period. In most of the cities, solid waste handling remains primitive, and well-organized procedures for it have not been established. Traditional methods of disposal, with marginal inclusion of modern conveniences, appear to be the common practice. In general, the shortcomings of the prevailing practices can be summarized as follows: The municipal solid waste management systems (MSWMSs) in this province include unsegregated collection and open dumping of municipal solid wastes. Separation of municipal solid waste in this province is in the hands of scavengers. The MSWMSs in this province lack essential infrastructure. Thus, design and implementation of modern MSWMSs in this province are essential. Principal criteria for and methods of implementing these systems are as follows: (1) rationally evaluating all functional elements so that they operate in a steady-state or equilibrium manner; (2) creating all support elements for the MSWMS in each city; (3) introducing gradual privatization of MSWMS activities; (4) creating guidelines, regulations, and instructions for all elements of MSWMSs; and (5) giving priorities to source separation and recycling programs. This paper reviews the present status of MSWMSs in eight major cities of Kurdistan Province and outlines the principle guidelines and alternatives for MSWMSs.

    Epigenetic mineral deposits in the Tintina Gold Province are generally characterized by high concentrations of arsenic and antimony in their mineral assemblage. A total of 347 samples (ground water, surface water, and stream sediment) were collected to investigate the distribution and mobility of arsenic and antimony in the environment near known mineral deposits. Samples were collected from east to west at Keno Hill and Brewery Creek, Yukon, Canada; and Cleary Hill, True North, Scrafford Mine, Fairbanks, Ryan Lode, Stampede Creek, Slate Creek, and Donlin Creek, all in Alaska. Surface- and ground-water samples are all slightly acidic to near-neutral in pH (5-8), have a wide range in specific conductance (surface water 17-2,980 microsiemens per centimeter and ground water 170-2,940 microsiemens per centimeter), and show elevated dissolved arsenic and antimony concentrations (arsenic in surface water is less than 1 to 380 micrograms per liter and in ground water is less than 1 micrograms per liter to 1.5 milligrams per liter; antimony in surface water is less than 2 to 660 micrograms per liter and in ground water is less than 2 to 60 micrograms per liter). Stream sediments downstream from these deposits have high concentrations of arsenic and antimony (arsenic median is 1,670 parts per million, maximum is 10,000 parts per million; antimony median is 192 parts per million, maximum is 7,200 parts per million). The mobility of arsenic and antimony is controlled by the local redox environment, with arsenic being less mobile in oxidized surface waters relative to antimony, and arsenic more mobile in reduced ground water. These factors suggest that both antimony and arsenic may be useful pathfinder elements in water and sediment for targeting similar style deposits elsewhere in the Tintina Gold Province.

    Waste management workers (WMWs) around the world are at risk of work-related health disorders. The influence of employment duration on individuals occupationally exposed to solid waste was investigated in this study. The study comprised (n = 280) 180 WMWs and 100 controls. Employment duration was obtained from questionnaire survey and categorized into three groups: group I (0.5-2 years), group II (>2-4 years) and group III (>4-6 years). Blood sample (10 ml) was collected from the antecubital vein of subjects for analysis. WMWs exhibited significantly (p < 0.001) elevated inflammatory markers (erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and ceruloplasmin (Cp)) relative to control. While Cp increased, ESR and CRP decreased with increasing WMWs' employment duration. Alteration in oxidant/antioxidant markers was characterized by significant (p < 0.001) decrease in ferric-reducing ability of plasma (FRAP) and catalase activity together with marked (p < 0.01) elevation of thiobarbituric acid reactive substances (TBARS) and uric acid (UA). TBARS, UA and FRAP increased while catalase decreased with WMWs' employment duration. In addition, WMWs exhibited significantly (p < 0.01) elevated immunoglobulin A (IgA) and IgG, which also increased and decreased, respectively, with job duration. The significantly (p < 0.01) decreased haemoglobin and haematocrit levels as well as the significantly (p < 0.001) elevated total leukocytes in WMWs increased with employment duration. Alanine aminotransferase increased and albumin decreased significantly (p < 0.05) in WMWs, and these changes also increased and decreased, respectively, with job duration. Data suggest that levels of alteration of important systemic markers of health/disease are related to WMWs' employment or exposure duration.

  11. Studies of geology and hydrology in the Basin and Range province, southwestern United States, for isolation of high-level radioactive waste-characterization of the Death Valley region, Nevada and California

    The Death Valley region, Nevada and California, in the Basin and Range province, is an area of about 80,200 sq km located in southern Nevada and southeastern California. Precambrian metamorphic and intrusive basement rocks are overlain by a thick section of Paleozoic clastic and evaporitic sedimentary rocks. Mesozoic and Cenozoic rocks include extrusive and intrusive rocks and clastic sedimentary rocks. Structural features within the Death Valley indicate a long and complex tectonic evolution from late Precambrian to the present. Potential repository host media in the region include granite and other coarse-grained plutonic rocks, ashflow tuff, basaltic and andesitic lava flows, and basin fill. The Death Valley region is composed largely of closed topographic basins that are apparently coincident with closed groundwater flow systems. In these systems, recharge occurs sparingly at higher altitudes by infiltration of precipitation or by infiltration of ephemeral runoff. Discharge occurs largely by spring flow and by evaporation and transpiration in the playas. Death Valley proper, for which the region was named, is the ultimate discharge area for a large, complex system of groundwater aquifers that occupy the northeastern part of the region. The deepest part of the system consists of carbonate aquifers that connect closed topographic basins at depth. The discharge from the system occurs in several intermediate areas that are geomorphically, stratigraphically, and structurally controlled. Ultimately, most groundwater flow terminates by discharge to Death Valley; groundwater is discharged to the Colorado River from a small part of the region.

    This paper uses the aggregate data from the Public Use Microdata Files (PUMF) of Canadian National Population Health Survey to estimate income related health inequalities across the ten Canadian provinces. The unique features of the PUMF allow for a meaningful cross-provincial comparison of health indices and their measured inequalities. It concludes that health inequalities favouring the higher income people do exist in all provinces when health status is either self assessed or measured by the health utility index. Moreover, it finds considerable variations in measured health inequalities across the provinces with consistent rankings for certain provinces.

  13. Uranium provinces of North America; their definition, distribution, and models

    1996-01-01

    Uranium resources in North America are principally in unconformity-related, quartz-pebble conglomerate, sandstone, volcanic, and phosphorite types of uranium deposits. Most are concentrated in separate, well-defined metallogenic provinces. Proterozoic quartz-pebble conglomerate and unconformity-related deposits are, respectively, in the Blind River?Elliot Lake (BRELUP) and the Athabasca Basin (ABUP) Uranium Provinces in Canada. Sandstone uranium deposits are of two principal subtypes, tabular and roll-front. Tabular sandstone uranium deposits are mainly in upper Paleozoic and Mesozoic rocks in the Colorado Plateau Uranium Province (CPUP). Roll-front sandstone uranium deposits are in Tertiary rocks of the Rocky Mountain and Intermontane Basins Uranium Province (RMIBUP), and in a narrow belt of Tertiary rocks that form the Gulf Coastal Uranium Province (GCUP) in south Texas and adjacent Mexico. Volcanic uranium deposits are concentrated in the Basin and Range Uranium Province (BRUP) stretching from the McDermitt caldera at the Oregon-Nevada border through the Marysvale district of Utah and Date Creek Basin in Arizona and south into the Sierra de Pe?a Blanca District, Chihuahua, Mexico. Uraniferous phosphorite occurs in Tertiary sediments in Florida, Georgia, and North and South Carolina and in the Lower Permian Phosphoria Formation in Idaho and adjacent States, but only in Florida has economic recovery been successful. The Florida Phosphorite Uranium Province (FPUP) has yielded large quantities of uranium as a byproduct of the production of phosphoric acid fertilizer. Economically recoverable quantities of copper, gold, molybdenum, nickel, silver, thorium, and vanadium occur with the uranium deposits in some provinces. Many major epochs of uranium mineralization occurred in North America. In the BRELUP, uranium minerals were concentrated in placers during the Early Proterozoic (2,500?2,250 Ma). In the ABUP, the unconformity-related deposits were most likely formed

    The Bonneville region of the Basin and Range province in westcentral Utah and adjacent Nevada includes several basins lying south of the Great Salt Lake Desert. Physiographically, the region consists of linear, north-trending mountain ranges separated by valleys, many of which are closed basins underlain by thick sequences of fill. Surface drainage of open basins and ground-water flow is to the Great Salt Lake Desert. In structure and composition the ranges are faulted Paleozoic rocks, locally intruded by Mesozoic and Tertiary plugs and stocks. In the southern and northeastern parts of the region, volcanic rocks are widespread and form large parts of some mountain ranges. The Paleozoic sedimentary rocks include great thicknesses of carbonate rocks which compose a significant aquifer in the regionMedia considered to have potential for isolation of high-level radioactive waste in the region include intrusive rocks, such as granite; ash-flow tuff; and basalt and basaltic andesite lava flows. These rock types, basin fill, and possibly other rock types, may have potential as host media in the unsaturated zone. Quaternary tectonism in the region is evidenced by seismic activity, local areas of above-normal geothermal heat flow, Quaternary faulting, late Cenozoic volcanic activity, and active vertical crustal movement. The Bonneville region is part of a large ground-water flow system that is integrated partly through basin-fill deposits, but largely through an underlying carbonate-rock sequence. The region includes: (1) several topographically closed basins with virtually no local surface discharge that are drained by the underlying carbonate-rock aquifer; (2) closed basins with local surface discharge by evapotranspiration; and (3) basins open to the Great Salt Lake Desert that discharge by groundwater underflow and evapotranspiration. The carbonate-rock aquifer discharges to large springs in the Desert and in basins tributary to the Desert. The climate is arid to

    Although the extraction of mineral wealth has been the major influence in the history of Johannesburg and the surrounding Witwatersrand regions (with about 45% of all gold ever mined coming from there), the discovery of now-famous hominid fossils at the Sterkfontein Caves, and the convening of the world's largest-ever conference on environment and development, are setting a new stage for the future. The United Nations began the second Development and Environment Conference in Johannesburg on August 26, 2002. This meeting addresses the implementation of international goals to fight poverty and protect the global environment that were established at the first such conference held in Rio de Janeiro in 1992. The Johannesburg summit involves about forty thousand participants, and perhaps 100 world leaders. One of several official opening ceremonies for the conference was held at the Sterkfontein Caves to recognize the outstanding universal value of the paleo-anthropological fossils found there.

    The Paleozoic crudes typically have low densities at 20/sup 0/C, low contents of resins, high viscosities at 20/sup 0/C, rather high solid points, and high contents of solid paraffins. The Paleozoic crudes are in no way inferior in quality to the Mesozoic crudes of Tomsk province, and are even better in some respects (yields of high-V.I. and medium-V.I. oils). They can be processed with either a fuel/lube or petrochemical refining scheme. Finds that the crudes from the Ostaninsk and SeveroOstaninsk fields, in terms of their paraffin and sulfur contents and other indexes, are similar to the Jurassic crudes of the Zhetybai field on the Mangyshlak peninsula. These 2 crudes and the Chkalovsk crude, even though the high wax contents offer problems in production and transportation, can serve as good raw materials for fuel and oil production, and also for the manufacture of liquid and solid paraffins.

    To investigate the association between occupation and lung cancer risk in Leningrad Province, Russia, we identified 540 pathologically diagnosed lung cancer cases (474 males and 66 females) and 582 controls (453 males and 129 females) from the 1993-1998 autopsy records of the 88 state hospitals of the Province. Lifetime occupational histories were obtained from personal records coded according to the standard Russian occupational classification system. Lung cancer risk was increased in workers in the manufacturing industry, particularly in the food industry and wholesale/retail trade and in the miscellaneous manufacturing industry. An increased risk was also found in subjects employed in chemical and metal production for 10 years or more. When we considered the association between specific occupations and lung cancer, waste incineration operators and loaders exhibited an excess risk that increased with employment duration. The present study, which is the first to evaluate the risk of lung cancer by occupation in Russia, suggests the presence in Leningrad Province of exposure in the workplace to lung carcinogens that require further characterization to develop targeted and effective preventive measures.

    The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geology-based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States, focusing on the distribution, quantity, and availability of oil and natural gas resources. The USGS has completed an assessment of the undiscovered oil and gas potential of the Eastern Oregon and Washington Province of Oregon and Washington (USGS Province 5005). The province is a priority Energy Policy and Conservation Act (EPCA) province for the National Assessment because of its potential for oil and gas resources. The assessment of this province is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (stratigraphy, sedimentology, petrophysical properties), and hydrocarbon traps (trap formation and timing). In the Eastern Oregon and Washington Province, the USGS used this geologic framework to define one total petroleum system and two assessment units within the total petroleum system, and quantitatively estimated the undiscovered gas resources within each assessment unit.

    An investigation of the geohydrologic system in the Ozark Plateaus province (index map and Fenneman, 1938) has been made as part of the Central Midwest Regional Aquifer-System Analysis (Jorgenson and Signor, 1981), a major study that encompasses parts of 10 States. The study is one of several by the U.S. Geological Survey that are designed to increase knowledge of the flow regime and geohydrologic properties of regional aquifer systems in the United States. Because a large quantity of fresh groundwater is available in aquifers underlying the Ozark Plateaus province, a subregional project has been established to study the geohydrologic units of this area in more detail than is practical in the regional study. The stratigraphic relationship among the primary geohydrologic units in the Ozark Plateaus province is discussed in Chapter A of this Hydrologic Investigations Atlas series. This chapter focuses on the Ozark aquifer, a geohydrologic unit within the Ozark Plateaus aquifer system underlying the Ozark Plateaus province.

    Objective: The present study is based on an ethnobotanical research project conducted in Hormozgan province that is located in south of Iran, bordering waters of the Persian Gulf and Oman Sea. This survey was carried out in order to recover the ethnobotanical and ethnomedicinal knowledge of the residents of this province. They are using medicinal and functional plants for treating or preventing several diseases. Materials and Methods: Ethnobotanical data sheets were run with the native inhabitants and people of the province by arranging frequent field trips to different parts of the province and direct interviews with them especially those who were more familiar with the plants and their usage. Results: A total of 150 plant species belonging to 53 families were recorded for their ethnobotanical and ethnomedicinal uses among the people of province. The records were developed by scientific names, family names, local names, medicinal parts used, different ways of their application, and traditional uses of the plants. There was high compliance in the use of plants in painful disorders, gastrointestinal, and dermatological diseases. Conclusion: This study revealed that the people of Hormozgan province have a rich knowledge of natural resources. The use and consumption of medicinal plants are still important parts of their life. Rational use of native medicinal plants may benefit and improve their living standards and quality of life. The results of this study can be used as a basis for selecting herbs for further pharmacological, phytochemical, and pharmacognostical studies. PMID:25050260

    This study presents an analysis of the causes of so-called honor killings in the context of "customary homicide" and a discussion of preventive measures. Finalized case files of customary homicide between January 1, 2007 and December 31, 2012 were retrospectively examined in Diyarbakir Province, Turkey. Of a total of 28 case victims, 17 (60.7%) were females and 11 (39.3%) were males. All perpetrators were male. There was a significant difference between male and female victims in terms of economic independence (p=0.000). A direct blood relationship or relationship by marriage (such as brother-in-law) was found to have a significant association with the gender of the victim (p<0.001). Multilevel educational activities targeting a transformation of the perception of women by society, replacement of patriarchal models with more modern attitudes, and encouragement of individuality may represent effective strategies that may help reduce the number of customary homicide, which represents a multifaceted problem. © 2015 American Academy of Forensic Sciences.

    The Pogo lode gold deposit was discovered in eastern Alaska in the early 1990s and provided the opportunity to study elemental distribution and mobility in the natural environment prior to mine development. Studying mineralized systems prior to mining allows us to compare the natural biogeochemical signature in mineralized versus nonmineralized areas. The resultant data and interpretation also provide a baseline for evaluating what, if any, changes in elemental distribution result from development. This report investigates the chemistry of stream water, streambed sediment, and soil in the context of regional bedrock geology. The major-ion chemistry of the waters reflects a rock-dominated aqueous system, and the waters are classified as Ca2+ and Mg2+ - HCO3- to Ca2+ and Mg2+ - SO4-2 waters. Creeks draining the gneissic lithologies tend to be more sulfate dominated than those draining the intrusive units. Sulfate also dominated creeks draining mineralized areas; however, the underlying paragneiss unit could be contributing substantially to the sulfate concentration, and the sulfate concentration in these creeks may reflect a complex baltholith-paragneiss boundary rather than mineralization. Arsenic concentrations in bed sediments were elevated in mineralized areas relative to nonmineralized areas. Elevated concentrations of nickel, chromium, iron, manganese, and cobalt appear to reflect the presence of ultramafic rocks in the drainage. In general, aqueous metal concentrations were below the State of Alaska’s Aquatic Life Criteria and Drinking Water Standards, with the exception of arsenic in stream water, which ranged in concentration from less than 1 to 14 micrograms per liter (μg/L) and exceeded the drinking water standard at one site. The arsenic and antimony concentration in the A, B, and C soil horizons ranged from 3 to 410 milligrams per kilogram (mg/kg), 6.1 to 440 mg/kg, and 2 to 300 mg/kg, respectively, for arsenic and 0.4 to 24 mg/kg, 0.6 to 25 mg

    The enigmatic Gamburstev Subglacial Mountains (GSM) in the interior of East Antarctica, have remained the least understood mountain range on earth, since their discovery some 50 years ago. An improved knowledge of the GSM region is however essential to underpin reconstructions of the Antarctic cryosphere and climate evolution. The GSM are a key nucleation site for the inception of the East Antarctic Ice Sheet approximately 34 Ma ago, and the adjacent Lambert Glacier played a pivotal role for ice sheet dynamics throughout the Neogene (23-0 Ma). The GSM province may also provide tectonic controls for major subglacial lakes flanking the range. In addition, the ice encasing the GSM province has been inferred to contain the oldest detailed climate record of the planet, a prime target for future deep ice core drilling. With the overarching aim of accomplishing the first systematic study of the cryosphere and lithosphere of the GSM province we launched a new geophysical exploration effort- AGAP (Antarctica’s Gamburtsev Province)-, a flagship programme of the International Polar Year. The aerogeophysical and seismology components of AGAP were accomplished by pooling resources from 7 nations. We deployed 2 Twin Otters, equipped with state-of-the art geophysical instrumentation and operating from two remote field camps on either side of Dome A. Over 120,000 line-km of new airborne radar, laser, aerogravity and aeromagnetic data survey were collected during the 2008/09 field campaign. Our grids of ice surface, ice thickness, subglacial topography, and gravity and magnetic anomalies provide a new geophysical foundation to analyse the GSM province, from the surface of the East Antarctic Ice Sheet down to mantle depths beneath the Precambrian shield. The anomalously high-elevation, alpine-type landscape of the GSM is now mapped with unprecedented detail. Two distinct branches of a subglacial rift system are imaged along the north-western and north-eastern margins of the

    1987-01-01

    The coal fields of the Unites States can be divided into six major provinces. The Appalachian and Interior Provinces contain dominantly bituminous coal in strata of Pennsylvanian age. The coal seams are relatively thin and are mined both by surface and underground methods. Sulfyur content is low to moderate in the Appalachian Province, generally high in the Interior province. The Gulf Coastal Plain Province, in Texas and neighboring states, contains lignite of Eocene age. The seams are 3-25 ft (0.9-7.5 m) thick and are minded in large open pits. The Northern Great Plains Province has lignite and subbituminous coal of Cretaceous, Paleocene and Eocene age. The coal, largely very low in sulfur, occurs in beds up to 100 ft (30 m) thick and is strip-mined. The Rocky Mountain Province contains a great variety of coal deposits in numerous separate intermontane basins. Most of it is low-sulfur subbituminous to bituminous coal iof Creatceous and early Tertiary age. The seams range from a few feet to over 100 ft (30 m) thick. Strip-mining dominates but underground mines are important in Utah and Colorado. The Pacific Coast Province, which includes Alaska, contains enormous cola resources but has seen little mining. The coal is highly diverse in physical character and geologic setting. ?? 1987.

  12. Martian Provinces From Neutron and Gamma Spectrometry

    NASA Astrophysics Data System (ADS)

    Gasnault, O.

    2003-12-01

    This study intends to identify and characterize the major provinces at the surface of Mars. We used the data from the Neutron Spectrometer (NS) and the Gamma-ray Sensor Head (GSH) aboard Mars Odyssey. NS data help to define broad provinces that should present uniform composition. GSH data can be then summed over these provinces to derive their chemical compositions with good statistics. At the present stage, we manage to conduct the first step that identifies the provinces, while the second step is still under progress to characterize them. Variations in NS epithermal and fast neutron data are largely dominated by the distribution of hydrogen and carbon at the surface or at shallow depths. Neutrons are also affected by the presence of an atmosphere. To limit these effects, we chose frost free data (i.e. measured during the summer at high-latitudes), between -60 and +60 degrees latitude, and corrected for atmospheric thickness (normalization to 16 g/cm2). On the other hand, it has been demonstrated that neutron fluxes can be used as a proxy for composition: thermal neutrons are strongly attenuated by absorbing elements such as iron, titanium, chlorine, gadolinium, and samarium; on the contrary, the fast neutron flux increases in presence of high-atomic mass elements such as iron or titanium. For a dry and airless body it is known that the ratio of epithermal over fast neutron counts is correlated to the ratio of thermal over fast neutron counts. This correlation leads to a unique parameter, which characterizes the various soil compositions. A similar behaviour has been observed within our subset of NS data. Effects of hydrogen and carbon are quite obvious, allowing us to focus on secondary components, which are driven by soil composition. From there, we derived four provinces besides the poles. The first province is made of H-rich equatorial regions (Arabia Terra and south of Lucus Planum). The second and third provinces are found north and south of the crustal

    1982-01-01

    The recognition of some Martian landforms as volcanoes is based on their morphology and geologic setting. Other structures, however, may exhibit classic identifying features to a varying or a less degree; these may be only considered provisionally as having a volcanic origin. Regional geologic mapping of the western hemisphere of Mars from Viking images has revealed many more probable volcanoes and volcanotectonic features than were recognized on Mariner 9 pictures. These abundant volcanoes have been assigned to several distinct provinces on the basis of their areal distribution. Although the Olympus-Tharsis region remains as the principle center of volcanism on Mars, four other important provinces are now also recognized: the lowland plains, Tempe Terra plateau, southern highlands (in the Phaethontis and Thaumasia quadrangles), and a probable ignimbrite province, situated along the highland-lowland boundary in Amazonis Planitia. Volcanoes in any one province vary in morphlogy, size, and age, but volcanoes in each province tend to have common characteristics that distinguish that particular group.

    This study measures the process of convergence in the state of health among the provinces and regions of Spain during 1980-2001 in order to analyse the possible influence of the decentralisation of healthcare management to the regions in this period. Sigma and beta convergence models, traditionally employed in macroeconomics, have been used, taking Life Expectancy at Birth (LEB) and Infant Mortality (IM) as health indicators. The analysis was carried out at two territorial levels: provinces and regions. The results reveal that the process of decentralisation either does not affect convergence or leads to divergence in health. Indeed, in the case of IM the so-called change of role scenario seems to have occurred. Thus, certain provinces with initially poor indicators have improved, overtaking those that were originally in a better position. The final result, however, is of greater dispersion than initially.

    According to the framework of "Pressure-State-Response", this study established an indicator system which can reflect comprehensive risk of environment and health for an area at large scale. This indicator system includes 17 specific indicators covering social and economic development, pollution emission intensity, air pollution exposure, population vulnerability, living standards, medical and public health, culture and education. A corresponding weight was given to each indicator through Analytical Hierarchy Process (AHP) method. Comprehensive risk assessment of the environment and health of 58 counties was conducted in the Jiangsu province, China, and the assessment result was divided into four types according to risk level. Higher-risk counties are all located in the economically developed southern region of Jiangsu province and relatively high-risk counties are located along the Yangtze River and Xuzhou County and its surrounding areas. The spatial distribution of relatively low-risk counties is dispersive, and lower-risk counties mainly located in the middle region where the economy is somewhat weaker in the province. The assessment results provide reasonable and scientific basis for Jiangsu province Government in formulating environment and health policy. Moreover, it also provides a method reference for the comprehensive risk assessment of environment and health within a large area (provinces, regions and countries).

    The Wyoming Province is an Archean craton which underlies portions of Idaho, Montana, Nevada, Utah, and much of Wyoming. The cratonic block consists of Archean age granite-gneiss with interspersed greenstone belts and related supracrustal terranes exposed in the cores of several Laramide uplifts. Resources found in the Province and in the adjacent accreted Proterozoic terrane include banded iron formation, Au, Pt, Pd, W, Sn, Cr, Ni, Zn, Cu, and diamonds. The Province shows many similarities to the mineral-rich cratons of the Canadian shield, the Rhodesian and Transvaal cratons of southern Africa, and the Pilbara and Yilgarn blocks of Western Australia, where much of the world's precious and strategic metal and gemstone resources are located.

  18. Lithospheric Deformation Along the Southern and Western Suture Zones of the Wyoming Province

    The Wyoming Province is an Archean craton that played an early role in the construction and growth of the North American continent. This region, which encompasses the majority of modern day Wyoming and southern Montana, initially collided with other Archean blocks in the Paleoproterozoic (2.0-1.8 Ga), creating the Canadian Shield. From 1.8-1.68 Ga, the Yavapai Province crashed into the Wyoming Province, suturing the two together. The accretion of the Yavapai Province gave way to the Cheyenne Belt, a deformational zone that exists along the southern border of the Wyoming Province where earlier studies have found evidence for crustal imbrication and double a Moho. Current deformation within the Wyoming province is due to its interaction with the Yellowstone Hotspot, which is currently located in the northwest portion of the region. This study images the LAB along the western and southern borders of the Wyoming Province in order to understand how the region's Archean lithosphere has responded to deformation over time. These results shed light on the inherent strength of Archean cratonic lithosphere in general. We employ two methods for this study: common conversion point (CCP) stacking of S to P receiver functions and teleseismic and ambient Rayleigh wave dispersion. The former is used to image the LAB structure while the latter is used to create a velocity gradient for the region. Results from both of the methods reveal a notably shallower LAB depth to the west of the boundary. The shallower LAB west of the Wyoming Province is interpreted to be a result of lithospheric thinning due to the region's interaction with the Yellowstone Hotspot and post-Laramide deformation and extension of the western United States. We interpret the deeper LAB east of the boundary to be evidence for the Wyoming Province's resistance to lithospheric deformation from the hotspot and tectonic processes. CCP images across the Cheyenne Belt also reveal a shallower LAB under the western

    Public health problems in armed conflicts have been well documented, however, effective national health policies and international assistance strategies in transition periods from conflict to peace have not been well established. After the long lasted conflicts in Sri Lanka, the Government and the rebel LTTE signed a cease-fire agreement in February 2002. As the peace negotiation has been disrupted since April 2003, a long-term prospect for peace is yet uncertain at present. The objective of this research is to detect unmet needs in health services in Northern Province in Sri Lanka, and to recommend fair and effective health strategies for post-conflict reconstruction. First, we compared a 20-year trend of health services and health status between the post-conflict Northern Province and other areas not directly affected by conflict in Sri Lanka by analyzing data published by Sri Lankan government and other agencies. Then, we conducted open-ended self-administered questionnaires to health care providers and inhabitants in Northern Province, and key informant interviews in Northern Province and other areas. The major health problems in Northern Province were high maternal mortality, significant shortage of human resources for health (HRH), and inadequate water and sanitation systems. Poor access to health facilities, lack of basic health knowledge, insufficient health awareness programs for inhabitants, and mental health problems among communities were pointed by the questionnaire respondents. Shortage of HRH and people's negligence for health were perceived as the major obstacles to improving the current health situation in Northern Province. The key informant interviews revealed that Sri Lankan HRH outside Northern Province had only limited information about the health issues in Northern Province. It is required to develop and allocate HRH strategically for the effective reconstruction of health service systems in Northern Province. The empowerment of inhabitants

  20. A probe into reasons for international migration in Fujian Province.

    PubMed

    Zhu, G

    1990-01-01

    In this paper, the author discusses the extent of international migration from China's Fujian Province and considers the reasons behind the migration. The most recent estimates place China's overseas population at 22.1 million, 19 million (88%) of which are concentrated in Southeast Asia. According to the author's calculations, at least 7 million of the Chinese overseas population are of Fujian descent. Indonesia alone holds some 3.3 million Fujianese. Malaysia, Singapore, and the Philippines account for most of the remaining Fujianese overseas population. Having established the extent of international migration from the Fujian Province, the author attempts to establish the reasons behind it. The author first considers the historical origins of Fujianese international migration, from its early states (end century B.C.-17th century) to modern times *18-early 20th century) to the current period (1949-present). The author then examines the reasons behind the migration, primarily the social environment and individual behavior. Finally, the author provides categories of international migration, stressing that these categories often overlap or coincide. Most of the early migration was "spontaneous" -- essentially, an unplanned occurrence. During the modern period, most migration was "forced" by the contract labor system instituted by colonialists. Political and social upheaval also prompted "provoked" international migration. And following the Chinese Revolution, "free" migration allowed many to return home or to join relative abroad.

    Dogs play an important role in rabies transmission throughout the world. In addition to the severe human rabies situation in China, spillover of rabies virus from dogs in recent years has caused rabies outbreaks in sheep, cattle and pigs, showing that there is an increasing threat to other domestic animals. Two livestock rabies outbreaks were caused by dogs in Shanxi province, China from April to October in 2015, resulting in the deaths of 60 sheep, 10 cattle and one donkey. Brain samples from one infected bovine and the donkey were determined to be rabies virus (RABV) positive by fluorescent antibody test (FAT) and reverse transcription polymerase chain reaction (RT-PCR). The complete RABV N genes of the two field strains, together with those of two previously confirmed Shanxi dog strains, were amplified, sequenced and compared phylogenetically with published sequences of the N gene of RABV strains from Shanxi and surrounding provinces. All of the strains from Shanxi province grouped closely, sharing 99.6 %-100 % sequence identity, indicating the wide distribution and transmission of dog-mediated rabies in these areas. This is the first description of donkey rabies symptoms with phylogenetic analysis of RABVs in Shanxi province and surrounding regions. The result emphasizes the need for mandatory dog rabies vaccination and improved public education to eradicate dog rabies transmission.

    Our study represents the first attempt to describe biogeographic provinces for North American (México, United States, and Canada) turtles. We analyzed three nested data sets separately: (1) all turtles, (2) freshwater turtles, and (3) aquatic turtles. We georeferenced North American turtle distributions, then we created presence–absence matrices for each of the three data sets. We used watershed unit as biogeographic units. We conducted an unweighted pair-group method with arithmetic mean clustering analysis on each Jaccard index distance matrix from our watershed species matrices to delineate biogeographic provinces. Provinces were then tested for significant differences in species compositions in a global model with the use of a one-way analysis of similarity. We conducted a best subset of environmental variables with maximum (rank) correlation with community dissimilarities that determined the best model of abiotic variables explaining province delineation (i.e., climate, topography, and stream channel). To identify which species contributed the most to province delineations, we conducted an indicator species analysis and a similarity-percentage analysis. There were 16 all-turtle provinces, 15 freshwater provinces, and 13 aquatic provinces. Species compositions delineating the provinces were explained by abiotic variables, including mean annual precipitation, mean precipitation seasonality, and diversity of streams. Province delineations correspond closely with geographical boundaries, many of which have Pleistocene origins. For example, rivers with a history of carrying glacial runoff (e.g., Arkansas, Mississippi) sometimes dissect upland provinces, especially for aquatic and semiaquatic turtles. Compared with freshwater fishes, turtles show greater sensitivity to decreased temperature with restriction of most taxa south of the last permafrost maximum. Turtles also exhibit higher sensitivity to climatic, geomorphic, and tectonic instability, with richness

    The Arctic Alaska Petroleum Province, encompassing all the lands and adjacent Continental Shelf areas north of the Brooks Range-Herald arch, is one of the most petroleum-productive areas in the United States, having produced about 15 billion bbl of oil. Seven unitized oil fields currently contribute to production, and three additional oil fields have been unitized but are not yet producing. Most known petroleum accumulations involve structural or combination structural-stratigraphic traps related to closure along the Barrow arch, a regional basement high, which has focused regional hydrocarbon migration since Early Cretaceous time. Several oil accumulations in stratigraphic traps have been developed in recent years. In addition to three small gas fields producing for local consumption, more than 20 additional oil and gas discoveries remain undeveloped. This geologically complex region includes prospective strata within passive-margin, rift, and foreland-basin sequences. Oil and gas were generated from multiple source rocks throughout the region. Although some reservoired oils appear to be derived from a single source rock, evidence for significant mixing of hydrocarbons from multiple source rocks indicates a composite petroleum system. Both extensional and contractional tectonic structures provide ample exploration targets, and recent emphasis on stratigraphic traps has demonstrated a significant resource potential in shelf and turbidite sequences of Jurassic through Tertiary age. Recent estimates of the total mean volume of undiscovered resources in the Arctic Alaska Petroleum Province by the U.S. Geological Survey and U.S. Minerals Management Service are more than 50 billion bbl of oil and natural-gas liquids and 227 trillion ft3 of gas, distributed approximately equally between Federal offshore and combined onshore and State offshore areas.

    Based on the theories and methods of ecological footprint, the concept of marine ecological footprint was proposed. According to the characteristics of marine environment in Jiangsu Province, five sub-models of marine ecological footprints, including fishery, transporation, marine engineering construction, marine energy, and tidal flat, were constructed. The equilibrium factors of the five marine types were determined by using improved entropy method, and the marine footprints and capacities in Jiangsu Province from 2000 to 2008 were calculated and analyzed. In 2000-2008, the marine ecology footprint per capita in Jiangsu Province increased nearly seven times, from 36.90 hm2 to 252.94 hm2, and the ecological capacity per capita grew steadily, from 105.01 hm2 to 185.49 hm2. In 2000, the marine environment in the Province was in a state of ecological surplus, and the marine economy was in a weak sustainable development state. Since 2004, the marine ecological environment deteriorated sharply, with ecological deficit up to 109660.5 hm2, and the sustainability of marine economy declined. The high ecological footprint of fishery was the main reason for the ecological deficit. Tidal flat was the important reserve resource for the sustainable development of marine economy in Jiangsu Province.

    We present an exploratory approach to the interpretation of the elemental maps produced by the Odyssey Gamma-Ray Spectrometer (GRS). These maps benefit from a direct detection of elemental mass fractions and are used to delineate and characterize elementally homogeneous provinces in the mid-latitudinal martian surface on the basis of chemistry alone. This approach is different from assessing the elemental composition of regions previously defined by their geologic context. Multivariate statistical approaches are discussed and a combination of principal component and clustering analyses is applied on the GRS-based hydrogen, chlorine, potassium, silicon, iron, and calcium maps. At least three principal components must be considered to properly describe the compositional variability seen in the maps. The main component is likely driven by the degree of mantling through a GRS perspective, i.e. by materials enriched in mobile elements (Cl, H) and finer than 10-20 cm, at horizontal and depth scales of hundreds of kilometers and tens of centimeters, respectively. Elemental diversity is found in both mantled and less-mantled provinces, suggesting both local and regional sources for the surficial materials. The less-mantled regions appear to have compositions which include basaltic igneous rocks. Although there is an absence of obvious natural clusters in the data, a solution between five and eight elemental provinces seems optimal and is discussed (Amazonis-Tharsis and Sabaea-Arabia, Tempe and the southern highlands, Chryse and Utopia, Elysium-Tartarus, Acidalia-Arabia). Future investigation of the defined elemental provinces will involve integrating other types of data and geological information.

    Economic value of water and economic analysis of water use management in Gansu Province of China have attracted widespread public attention. With the socioeconomic development, research on water resources has become more important than before. In this study, we define "water productivity" as the changes of economic production outputs of sectoral activities in every cubic meter of water input, which is also the technical coefficient of water resource use in each sector. According to Computable General Equilibrium (CGE) framework, based on the Input-Output Table 2007 and water resources bulletin of Gansu Province, we introduced the water into the ORANI-G (A Generic Single-Country Computable General Equilibrium model) model through the nested constant elasticity of substitution (CES) production function to analyze the changes of economic productions caused by water supply changes. We then examined water productivity in different sectors. Empirical results showed that current water productivity is underestimated. Agricultural water productivity is lower than that of the secondary and tertiary industries, even although agricultural water use is the largest part of water use in Gansu Province, and therefore improving agricultural water productivity can greatly mitigate the water shortage. Simulation results indicate that industrial transformation and development of water-saving industries will also mitigate water scarcity. Moreover, sensitivity analysis shows that the empirical results are robust under different scenarios. The results also show that higher constant elasticity of substitution rate (CES) between water and other production factors will contribute to sustainable development.

    Cockroach surveys using sticky traps were conducted in urban areas of 14 Thailand provinces. At least 30 houses in each province were randomly sampled for cockroaches. Each house was trapped in three areas: kitchen, bedroom and outside. A total of 2,648 cockroaches was caught by 550 out of 1,542 traps (35.7%), from 337 of the 514 houses (65.6%). Overall, relative density ranged from 2.6 to 9.1 with an average of 5.2 cockroaches/house. On the average, 47.7% of the cockroaches were caught in the kitchen, 24.4% and 27.9% were caught in the bedroom and outside of dwellings, respectively. There were 10 species of cockroaches caught from the 14 provinces: Periplaneta americana (60.9%), Periplaneta brunnea (15.4%), Neostylopyga rhombiofolia (9.6%), Periplaneta australasiae (9.2%), Pycnoscelis surinamensis (3.3%), Blatella germanica (0.6%), Periplaneta fuliginosa (0.5%), Supella longipalpa (0.3%), Blatella lituricollis (0.15%) and Nauphoeta cinerea (0.05%), belonging to six genera. According to the surveys in this study, Periplaneta americana and Periplaneta brunnea were the most abundant cockroach species in urban Thailand, whereas the kitchen was the major habitat.

    Rodents are important reservoirs of rodent-borne infections worldwide, including Southeast Asia and Northeast Thailand (Isaan), where rodent consumption may be a source of rodent-borne diseases. The behavior of consuming rodents is related to a population's traditions, knowledge, cultural, and household contexts, among other factors. This cross-sectional survey was conducted in Khon Kaen Province, Thailand during November-December 2011. It aimed to elicit information about rodent consumption among residents of this province, and to identify factors associated with rodent consumption there. Multiple logistic regression analysis indicated that male gender, large family size, and use of rainwater as the main source of drinking water were positively associated with reported rodent consumption in this province, while having proper knowledge/attitudes towards animal-borne disease was negatively associated. These results provide evidence-base information for further studies, such as participatory ac- tion research, to further explore how people interact with rodents in different contexts. Further research is also needed to characterize risk of zoonotic diseases in relation to rodent consumption.

  13. Some Environmental Consequences of Large Igneous Provinces

    NASA Astrophysics Data System (ADS)

    Coffin, M. F.

    2009-12-01

    The formation of large igneous provinces (LIPs)—continental flood basalts, ‘volcanic’ margins, and oceanic plateaus—may impact the atmosphere, oceans, and biosphere by rapidly releasing huge amounts of particulates, magmatic volatiles (CO2, SO2, Cl, F, etc.), and potentially volatiles (CO2, CH4, SO2, etc.) from intruded sediments (e.g., carbonates, organic-rich shales, evaporites). A key factor affecting the magnitude of volatile release is whether eruptions are subaerial or marine; hydrostatic pressure inhibits vesiculation and degassing of relatively soluble volatile components (H2O, S, Cl, F) in deep water submarine eruptions, although low solubility components (CO2, noble gases) are mostly degassed even at abyssal depths. Directly or indirectly, such injections may cause changes in the atmosphere/ocean system that can lead to perturbations of atmosphere/ocean chemistry, circulation, ecology, and biological productivity. These changes can be global in extent, particularly if environmental conditions were at or near a threshold state or tipping point. LIPs may have been responsible for some of the most dramatic and rapid changes in the global environment. For example, between ~145 and ~50 Ma, the global ocean was characterized by chemical and isotopic variations (especially in C and Sr isotope ratios, trace metal concentrations, and biocalcification), relatively high temperatures, high relative sea level, episodic deposition of black shales (oceanic anoxic events), high production of hydrocarbons, mass extinctions of marine organisms, and radiations of marine flora and fauna. Temporal correlations between the intense pulses of igneous activity associated with LIP formation and environmental changes suggest more than pure coincidence. The 1783-84 eruption of Laki on Iceland provides the only historical record of the type of volcanism that constructs transient LIPs. Although Laki produced a basaltic lava flow representing only ~1% of the volume of a typical

    To understand the changes of schistosomiasis endemic situation in Sichuan Province, the upstream of Yangtze River basin, and the impact on schistosomiasis transmission in Three Gorges Reservoir area after the construction of Three Gorges Reservoir. The annual reports of the schistosomiasis endemic situation in Sichuan Province from 2000-2012, the data of the schistosomiasis surveillance sites in Sichuan Province from 2001-2012, the data of the schistosomiasis sampling survey in Sichuan Province in 2001, and the relevant reference of Three Gorges Reservoir were collected. The schistosomiasis prevalence in human and cattle, and Oncomelania hupensis snail status were investigated. The snail survey was implemented in Qianjin Village, Jianyang City, Sichuan Province, the nearest village to Three Gorges Reservoir Area. The schistosomiasis endemic situation presented a continuous declining state in Sichuan Province from 2000-2012, and reached the criteria of schistosomiasis transmission controlled in 2008. From 2012, 65.07% of endemic counties reached the criteria of schistosomiasis transmission interrupted. From 2006, no schistosome infected snails were found. In Qianjin Village, 1714 m2 environments were surveyed and no snails were found. The schistosomiasis endemic area and snail area are significantly reduced in Sichuan Province, the upstream of Yangtze River basin, after the construction of Three Gorges Reservoir. Therefore, the possibility of schistosomiasis endemic diffusing to Three Gorges Reservoir area is minimum.

    The presence of significant extension in the Basin and Range Province of the Western United States during the Cenozoic has been well-characterized geologically, but there is still uncertainty in our understanding of how this extension is accommodated within the crust and mantle lithosphere. One model suggests that deformation is accommodated through viscous flow in the lower crust; another that strain is distributed along a mega-detachment at the base of the crust. In this study, we test the models outlined above by imaging anisotropic and dipping structure beneath six long-running seismic stations (BMN, ELK, NEE, MNV, TPNV, WVOR) located within the physiographically-defined Basin and Range Province using Ps receiver function analysis. Events used in our analysis were limited to distances between 30° and 100° and magnitudes greater than 5.8. Seismograms were preprocessed, rotated to transverse and radial components, and filtered at 0.02-2 Hz. Data was inspected for quality, and direct wave arrivals were picked using SAC. Ps receiver functions were calculated using a multi-taper spectral cross-correlation technique, and binned as functions of both back azimuth and distance. Preliminary results indicate a coherent positive phase, interpreted to be the Moho, at 3.7-4.2 seconds for stations NEE, BMN, ELK, MNV, and WVOR. At TPNV, the Moho exhibits laterally complex behavior with a phase arrival at 4.3 to 5.4 seconds. Our results indicate the presence of significant energy on the transverse component at delay times of 2.8-5.2 seconds at stations WVOR, TPNV, and MNV. Within this time window, a polarity flip, indicative of dipping structure and/or anisotropy, occurs at 90° back azimuth at each of the three stations. Further work is needed to better constrain the origin of this structure and determine how the structure might be related to extension within the Basin and Range.

    2007-01-01

    Introduction The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas resources of the Raton Basin-Sierra Grande Uplift Province of southeastern Colorado and northeastern New Mexico (USGS Province 41). The Cretaceous Vermejo Formation and Cretaceous-Tertiary Raton Formation have production and undiscovered resources of coalbed methane. Other formations in the province exhibit potential for gas resources and limited production. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define two total petroleum systems and five assessment units. All five assessment units were quantitatively assessed for undiscovered gas resources. Oil resources were not assessed because of the limited potential due to levels of thermal maturity of petroleum source rocks.

    Colorectal cancer is one of the most common cancers. The aim of this study is determination its trends in Kerman province and individual cities separately until year 2016. This analytical and modeling study was based of cancer registry data of Kerman University of Medical Sciences, collected during 2001-2010. Among 20,351 cancer case, 792 were colorectal cancer cases in age group 18-93 years with a mean of 59.4 and standard deviation of 15.1. By applying time series and data trends, incidences were predicted until 2016 for the province and each city, with adjustment for population size. In colorectal cases, 413 (52%) were male, and 379 (48%) were female. The annual increasing rate in Kerman province overall was and can be expected to be 6%, and in the cities of the province Rafsanjan, Bardsir, Bam, Kerman, Baft, Sirjan, Jiroft, Kahnuj and Manujan had an increasing range from 5 to 14% by the year 2016. But in Ravar, Zarand and Shahrbabak reduction in rates of at least 2% could be predicted. The time series showed that the trend of colorectal cancer in female will increase 15% and in male 7% by year 2016. Given the trend of this cancer is increasing so that resources will be consumed in the treatment of the patients, efforts shoudlbe focused on prevention and early diagnosis of the disease. Screening could have an important role leading to improved survival.

    A maternal mortality audit was introduced in the Midlands Province (Zimbabwe) in order to identify which avoidable factors were involved most frequently. During the two-year study period, the maternal mortality rate was 137 per 100,000 total births. The main causes of death were uterine rupture, eclampsia, haemorrhage and caesarean section related accidents. An avoidable factor was identified among 87% of these deaths involving the health system in 57% of the cases and the patient in 33%. Access to the health facilities and transport problems only played a minor role.

    Detailed field studies of selected areas in the greenstone belts of the Slave Province of Canada were presented. This area was long cited as a type area by supporters of the (now generally abandoned) rift model of greenstone belts. It was shown that a plate tectonic interpretation accounted more successfully for the regional geology and identified four terranes that had experienced complex divergent and convergent histories between 2.7 and 3.4 Ga. A dismembered ophiolite was identified and a late episode of widespread granitic intrusion was recognized.

    Yunnan Province in China borders 3 countries (Vietnam, Laos, and Myanmar) in Southeast Asia. In the 1980s, a large-scale rabies epidemic occurred in this province, which subsided by the late 1990s. However, 3 human cases of rabies in 2000 indicated reemergence of the disease in 1 county. In 2012, rabies was detected in 77 counties; 663 persons died of rabies during this new epidemic. Fifty two rabies virus strains obtained during 2008–2012 were identified and analyzed phylogenetically by sequencing the nucleoprotein gene. Of the 4 clades identified, clades YN-A and YN-C were closely related to strains from neighboring provinces, and clade YN-B was closely related to strains from Southeast Asia, but formed a distinct branch. Rabies virus diversity might be attributed to dog movements among counties, provinces, and neighboring countries. These findings suggest that Yunnan Province is a focal point for spread of rabies between Southeast Asia and China. PMID:25144604

  12. Mantle Provinces under Eastern North America

    NASA Astrophysics Data System (ADS)

    Sigloch, K.

    2010-12-01

    I present a survey of mantle provinces (large-scale seismic anomalies) under North America, from the surface down to approximately 1500 km depth, and with a focus on the eastern half of the continent. It is based on multi-frequency tomography, which uses systematically frequency-dependent traveltime and amplitude measurements of teleseismic P-waves, together with finite-frequency modeling. A novel kind of rendering technique (``color-banded 3-D maps'') is used to make the mantle model's considerable structural complexity accessible. In the transition zone and below, the North American mantle is dominated by seismically fast provinces, which appear to be distinct subduction episodes of the Farallon plate. I attempt to date and interpret the various slab fragments by reconciling their present positions with paleo-trench locations from plate tectonic reconstructions, and with major geological surface episodes. The first-order surface division between stable East and tectonic West is found to have its equivalent in the mantle: slabs that were laid down before or after (east or west of) a big slab break that happened between 50 and 60 Myr. Some of the mantle provinces have not been discussed much previously, including (1) a seismically slow blanket overlying the oldest Farallon subduction beneath the East Coast; (2) a transition zone slab co-eval with the Laramide orogeny (ca. 80-60 Myr), which I discuss in analogy to the ``stagnant slab'' subduction style commonly found in the Western Pacific today; (3) the surprisingly deep, lower-mantle root of present-day Cascadia subduction; and (4) the very sharp boundaries (plate tears and breaks) that delineate slab fragments. Because it can be dated, the stagnating ``Laramide'' fragment turns out to be an anchor piece, about halfway through the Farallon's subduction history, relative to which the other fragments may be evaluated. Large vertical offsets across co-eval slabs indicate that vertical sinking velocity was highly

    Chemical provinces of Mars became definable[1-3] with the maps of elemental mass fractions generated with Mars Odyssey Gamma Ray Spectrometer (GRS) data[4,5]. Previous work highlighted the Elysium lava flow province as anomalous, with a depletion in K and Th relative to the average crust in the rest of Mars (ROM).[3] We characterize the elemental composition, geology, and geomorphology of the region to constrain the processes that have contributed to its evolution. We compare SE Elysium with its North West lava fields, advancing prior work on thermal evolution of the martian mantle.[6] Lava fields at both sites probably source from Elysium eruptions. Both show similar Si content, as well as a Ca-enrichment compared to ROM, consistent with prior models.[6,7] Nevertheless, the two fields are compositionally distinct from each other, with NW Elysium decisively depleted in Ca and Fe, but enriched in K and Th. Such distinctness, in elements that reflect magmatic fractionation, reveals the possibility that a single volcanic complex on Mars may evolve rapidly during the Amazonian era, causing variable flow compositions. Interestingly, a chemical province containing volcanics that is contemporaneous with Elysium, overlaps the Tharsis region.[3] Unlike Elysium, the K and Th distributions within Tharsis are indistinguishable from ROM. Meanwhile, the mass fraction signature in Tharsis is enriched in Cl and depleted in Si. Such contrast, in chemical anomalies between volcanic constructs of similar age, may indicate that the depletion of K and Th in SE Elysium did not arise from temporal evolution of the mantle.

    2015-04-01

    Models for the disruption of supercontinents have considered mantle plumes as potential triggers for continental extension and the formation of large igneous provinces (LIPs). An alternative hypothesis of top-down tectonics links large volcanic eruptions to lithospheric delamination. Here we argue that the formation of several LIPs in Tarim, Yangtze, Lhasa and other terranes on the Eurasian continent was coeval with the assembly of the Pangean supercontinent, in the absence of plumes rising up from the mantle transition zone or super-plumes from the core-mantle boundary. The formation of these LIPs was accompanied by subduction and convergence of continents and micro-continents, with no obvious relation to major continental rifting or mantle plume activity. Our model correlates LIPs with lithospheric extension caused by asthenospheric flow triggered by multiple convergent systems associated with supercontinent formation.

  15. Exploring the Sandy Province of Herschel Crater

    NASA Image and Video Library

    2017-09-04

    This view from NASA's Mars Reconnaissance Orbiter shows the downwind stretches of a sand sheet in central part of the much larger Herschel Crater. This sandy province began kilometers upwind in a string of barchan sand dunes. As the north-to-south blowing wind weakened downwind, it could no longer fashion the sand into dunes but rather into amorphously-shaped sand sheets. While perhaps not awe-inspiringly beautiful, sand sheets can tell us about Mars' current and past environmental conditions as a piece of the puzzle for understanding habitability. Having dunes upwind of sheets is the opposite situation Earth has, where upwind sand sheets evolve downwind into sand dunes. This mystery is receiving ongoing research to to understand these sandy differences between Earth and Mars. https://photojournal.jpl.nasa.gov/catalog/PIA21933

    This investigation was carried out to determine the frequency of the fasciolosis in Erciş, a town in the Van province located in the Eastern Turkey. The study includes 500 asymptomatic subjects (322 males and 178 females) whose ages ranged from 5 to 75 years. In all subjects, stool samples were examined at initiation of the study and one week later to rule out pseudoparasitosis. The methods of flotation (in saturated saline solution) and sedimentation (in formalin-ether solution) were used in examination of the stool samples. Fasciola hepatica eggs were detected in nine (1.8%) out of 500 subjects. In conclusion, our data showed that the prevalence of human fasciolosis was high in our region because watercress consumption was common. We also think that human fasciolosis is more frequent than expected in Turkey. To determine the exact prevalence of the disease, extensive serological investigations should be performed in different regions of Turkey.

    Wyoming's Powder River Basin is one of those oil provinces that never quits. It currently is one of the more active areas in the Rocky Mountain region, and there are indications that suggest the latter half of this year could be more lively than the first half. The Wyoming Oil and Gas Conservation Commission listed 251 applications for drilling permits in June; 150 of them were for Powder River Basin counties. Operators indicate interest is building in the area for several reasons. Economic considerations are more favorable, money is more available, and there are ready markets for oil and associated natural gas. Drilling costs have decreased considerably, from $17/ft two years ago to $6.90-$7.70/ft.

    A forthcoming well about to spud off South Korea is planned to test the potential of an essentially unexplored rift basin. Should the well prove successful, it could open up a major new hydrocarbon producing province with substantial reserves. The well is being drilled in Block V which covers 7,000 sq km. is divided into two parts, and lies about 150 km south of the Korean peninsula close to Cheju Island. The larger Northern Block overlies the Fukue basin, which is a linear graben system oriented northeast-southwest. The Fukue basin is equivalent in size to the South Viking graben of the North Sea and the existence of a restricted marine source rock and play types at several stratigraphic levels helps to reinforce such a comparison Seismic mapping has revealed five prospects with combined most likely reserves of more than 1 billion bbl. The paper describes the basin evolution, source and migration of petroleum, reservoir and seals, and well location.

    Burn injuries are the most frequently occurring injuries among pediatric populations worldwide, and they are significant pediatric injuries in Iran. This study was conducted to analyze the pattern of pediatric burns in Khuzestan province in the south-west of Iran from April 2006 to March 2007. The location of the study was Taleghani Hospital, a sole center for burn patients in Khuzestan province. The number of patients with burns admitted to the center in 1 year (from April 2006 to March 2007) was 211. Data were obtained by reviewing the medical records of patients hospitalized at the center. Of the patients, 85 (40.3%) were female and 126 (59.7%) were male. Of the 85 female patients, 50 were from urban areas and 35 were from rural areas. Of the 126 male patients, 68 (54%) were from urban areas and 58 (46%) were from rural areas. The mean ± SE age of the children ranging between 0 and 11 years was 3.20 ± 0.188. Scalding was the predominant cause of burns and caused 86.7% of the burns. The age of the patients with scald injuries (2.95 ± 2.56 years) was significantly lower than that of patients with flame injuries (4.28 ± 3.3 years) (P=0.007). Correlation analysis showed that younger children and urban residents are more vulnerable to scald injuries. The mean body surface area of burns was 20.5 ± 10.26 cm in all patients. Scalding was the most common cause of burns. Age <4 years and residency in urban areas were the major factors increasing the risk of burn accidents in children in Khuzestan. An appropriate burn prevention program, with focus on education, is needed to prevent this injury.

    Phenylketonuria (PKU) is caused by variants in the phenylalanine hydroxylase (PAH) gene. We systematically investigated all 13 exons of the PAH gene and their flanking introns in 31 unrelated patients and their parents using next-generation sequencing (NGS). A total of 33 different variants were identified in 58 of 62 mutant PAH alleles. The prevalent variants with a relative frequency of 5 % or more were c.721C > T, c.1068C > A, c.611A > G, c.1197A > T, c.728G > A, c.331C > T, and c.442-1G > A. One novel variant was identified in this study-c.699C > G. We studied genotype-phenotype correlations using the Guldberg arbitrary value (AV) system, which revealed a consistency rate of 38 % (8/21) among the 21 predicted phenotypes. The genotype-based prediction of BH4 responsiveness was also evaluated, and 14 patients (45.2 %) were predicted to be BH4 responsive. This study presents the spectrum of PAH variants in Jiangsu province. The information obtained from the genotype-based prediction of BH4 responsiveness might be used for the rational selection of candidates for BH4 testing. • Phenylketonuria (PKU) is caused by variants in the phenylalanine hydroxylase (PAH) gene. • The spectrum of PAH variants in different Chinese populations has been reported. What is new: • This is the first report on the spectrum of PAH variants in Jiangsu province. • This study identified one novel PAH variant-c.699C>G-and and tries to show a genotype-phenotype relationship also regarding BH4-responsiveness.

  2. Differences in antiretroviral scale up in three South African provinces: the role of implementation management.

    South Africa's antiretroviral programme is governed by defined national plans, establishing treatment targets and providing funding through ring-fenced conditional grants. However, in terms of the country's quasi-federal constitution, provincial governments bear the main responsibility for provision of health care, and have a certain amount of autonomy and therefore choice in the way their HIV/AIDS programmes are implemented. The paper is a comparative case study of the early management of ART scale up in three South African provincial governments--Western Cape, Gauteng and Free State--focusing on both operational and strategic dimensions. Drawing on surveys of models of ART care and analyses of the policy process conducted in the three provinces between 2005 and 2007, as well as a considerable body of grey and indexed literature on ART scale up in South Africa, it draws links between implementation processes and variations in provincial ART coverage (low, medium and high) achieved in the three provinces. While they adopted similar chronic disease care approaches, the provinces differed with respect to political and managerial leadership of the programme, programme design, the balance between central standardisation and local flexibility, the effectiveness of monitoring and evaluation systems, and the nature and extent of external support and programme partnerships. This case study points to the importance of sub-national programme processes and the influence of factors other than financing or human resource capacity, in understanding intervention scale up.

    The Tintina gold province is an arc-shaped 2,000-kilometer-long metallogenic province that extends from northern British Columbia, through the Yukon Territory, and across and into southwestern Alaska. In the United States, the province remains a prime area for gold exploration and includes such large gold deposits as Pogo, Fort Knox-True North, and Donlin Creek. In recent years, gold exploration and development and mining activity have accelerated in the area. Plans have been discussed for public and private projects and infrastructures associated with development. A U.S. Geological Survey study undertaken from 2002 to 2007 provides a context for understanding why and how the mineral resources of the area were formed, why this area is so abundantly endowed, and how the environmental signatures that are characteristic of the area are related to the development of mineral resources. Characterization of natural baseline metal concentrations in the area's watersheds is necessary to address future land-use issues related to mining and/or infrastructure activities. A thorough understanding of water-rock and element-bioavailability processes will help predict the possible environmental impact of development. The five tasks of this study add to the science of defining and understanding an 'intrusion-related gold system.'

    1996-10-01

    Dr. Mpoudi Ngolle, director of Cameroon's national program against AIDS, stated in an August 1996 television interview that about 250,000 people were then infected with HIV in Cameroon. Dr. Amida Ghogomou believes that 78,000 of these infected people are in Northwest Province, perhaps the province of Cameroon with the largest number of people with HIV. People in the province aged 15-40 years old are the worst affected. About 40% of urban residents in Cameroon, Cote d'Ivoire, Ethiopia, Kenya, Benin, Mali, Rwanda, Tanzania, Zambia, Malawi, and Djibouti are thought to be infected with HIV. HIV has spread so rapidly because donor agencies such as the US Agency for International Development, World Health Organization, and European Union-sponsored programs stopped funding government and nongovernmental organization information/education/communication programs. To earn foreign currency, Cameroon depends largely upon the exportation of agricultural products such as cocoa, coffee, and bananas. However, few Cameroonians have thought seriously about the damaging impact AIDS morbidity and mortality will have upon the economy. Existing programs, especially those which target youths, need to be expanded.

    Background: Equine piroplasmosis (EP) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of EP is due to the persistent carrier state. Carrier animals to Babesia (Theileria) equi (Laveran 1901) and B. caballi (Nuttall, 1910) infestation could be identified by extremely sensitive PCR-based method. The purpose of this study was to identify the causative agents of equine piroplasmosis based on molecular and microscopic assays in equids from Kurdistan Province, Iran. Methods: Thirty one horse and mule blood samples were used with history of living in Kurdistan Province of Iran. The blood specimens were utilized for T. equi and B. caballi DNA identification by PCR and Giemsa stained smears for microscopic observation. Results: The results clearly showed the presence of B. (Theileria) equi DNA in 30 of 31 blood samples (96.77%), but the microscopic examination revealed the 3 of 31 positive Babesia like organisms in the red blood cells (9.67%). Conclusion: The obtained results demonstrated the presence of hidden B. (Theileria) equi infection in horses with previous habitance in Kurdistan Province of Iran. The carrier animals became a main source of infection and can transmit the disease. Therefore, hidden infection might be considered as a health threatening and limiting factor in animals used in therapeutic antisera research and production centers. PMID:27095973

    Alaska, the least explored of all United States regions, is estimated to contain approximately 40% of total U.S. undiscovered, technically recoverable oil and natural-gas resources, based on the most recent U.S. Department of the Interior (U.S. Geological Survey and Minerals Management Service) estimates. Northern Alaska, including the North Slope and adjacent Beaufort and Chukchi continental shelves, holds the lion's share of the total Alaskan endowment of more than 30 billion barrels (4.8 billion m3) of oil and natural-gas liquids plus nearly 200 trillion cubic feet (5.7 trillion m3) of natural gas. This geologically complex region includes prospective strata within passive-margin, rift, and foreland-basin sequences. Multiple source-rock zones have charged several regionally extensive petroleum systems. Extensional and compressional structures provide ample structural objectives. In addition, recent emphasis on stratigraphic traps has demonstrated significant resource potential in shelf and turbidite systems in Jurassic to Tertiary strata. Despite robust potential, northern Alaska remains a risky exploration frontier - a nexus of geologic complexity, harsh economic conditions, and volatile policy issues. Its role as a major petroleum province in this century will depend on continued technological innovations, not only in exploration and drilling operations, but also in development of huge, currently unmarketable natural-gas resources. Ultimately, policy decisions will determine whether exploration of arctic Alaska will proceed.

    Crustal rocks lose their magnetization at the Curie point temperature about 800K. Hence, the Curie isotherm is the bottom of the magnetized crust, which reflects the thermal state of the lithosphere rather than geological structure. A geothermal anomaly is obvious in Guangdong province. We study the spatial variation of the depth of the Curie isotherm under Guangdong province using aeromagnetic data. We employ the continuous model method and build a geothermal model with the Curie isothermal as a constrain condition to study the thermal state of crust under Guangdong province. The Guangdong Geology Bureau conducted an aeromagnetic survey over Guangdong province with a resolution of 0.02°×0.02°. The data cover the whole Guangdong region extending from 20.14°N to 25.64°N latitude and from 109.52°E to 117.22°E longitude, over 50,000 measuring points. After given the average magnetization and the average depth, undulations of Curie isotherm is expressed as a Fourier series using the linear approximate inversion formula of Peters (1949). The Fourier coefficients of the undulations of the Curie isotherm are obtained using the least square method. The result shows that average depth of Curie isothermal surface under Guangdong province is 18km, and the undulation is over 9km.Average depth of the Moho is 32km, which is well below the Curie isotherm. In Shaoguan, north of Guangdong province, both the Curie isotherm and the Moho surface are deeper. This is consistent with the low heat flow in this region, and can be interpreted as indicating thick lithosphere. In contrast a significantly shallower Curie isotherm and Moho are observed in Guangzhou. This is consistent with high heat flow in this region and can be interpreted as indicating thinner lithosphere due to the heating by a mantle plume. The Curie isotherm can indicate the thermal state of the deep crust and is a very powerful constraint for geothermal modeling.We built a convective geothermal model of Guangdong

    ...Even though eliminating malaria from the endemic margins is a part of the Global Malaria Action Plan, little guidance exists on what resources are needed to transition from controlling malaria to eliminating it. Using Philippines as an example, this study aimed to (1) estimate the financial resources used by sub-national malaria programs in different phases during elimination and (2) understand how different environmental and organizational factors may influence expenditure levels and spending proportions. The Philippines provides an opportunity to study variations in sub-national programs because its epidemiological and ecological diversity, devolved health system, and progressive elimination strategy all allow greater flexibility for lower-level governments to direct activities, but also create challenges for coordination and resource mobilization. Through key informant interviews and archival record retrieval in four selected provinces chosen based on eco-epidemiological variation, expenditures associated with provincial malaria programs were collected for selected years (mid-1990s to 2010). Results show that expenditures per person at risk per year decrease as programs progress from a state of controlled low-endemic malaria to elimination to prevention of reintroduction regardless of whether elimination was deliberately planned. However, wide variation across provinces were found: expenditures were generally higher if mainly financed with donor grants, but were moderated by the level of economic development, the level of malaria transmission and receptivity, and the capacity of program staff. Across all provinces, strong leadership appears to be a necessary condition for maintaining progress and is vital in controlling outbreaks. While sampled provinces and years may not be representative of other sub-national malaria programs, these findings suggest that the marginal yearly cost declines with each phase during elimination.

    OBIETTIVI: valutare l'andamento temporale della mortalità per patologie respiratorie nelle province pugliesi utilizzando dati omogenei per fonte e metodologia di calcolo. DISEGNO: analisi ecologica storica degli andamenti temporali di mortalità per tumori e patologie dell'apparato respiratorio nelle province pugliesi, in Puglia e nelle ripartizioni geografiche italiane dal 1933 al 2010. SETTING E PARTECIPANTI: i dati di mortalità e le popolazioni residenti sono di fonte Istat. Sono state esaminate tutte le cause di decesso, il tumore della laringe, il tumore del polmone, l'insieme dei tumori respiratori, la bronchite, la polmonite e la broncopolmonite considerate congiuntamente, e l'insieme delle patologie respiratorie. Le analisi sono disaggregate per sesso dal 1969. PRINCIPALI MISURE DI OUTCOME: rapporti standardizzati di mortalità (SMR%) in riferimento all'Italia, con intervalli di confidenza al 95%, e tassi di mortalità standardizzati col metodo diretto (TSD ) in riferimento alla popolazione standard europea. RISULTATI: dal 1933 al 2010, i TSD per tumori respiratori e per bronchiti diminuiscono in tutte le aree analizzate. Tuttavia, nelle province di Taranto, Brindisi e Lecce, l'SMR% per tumori respiratori, inferiore al riferimento nazionale fino agli anni Sessanta, si allinea (a Brindisi) e supera (a Lecce e Taranto) il riferimento negli anni successivi. Nelle province di Foggia e Bari il numero dei decessi per tumore del polmone è costantemente inferiore all'atteso. CONCLUSIONI: la ricostruzione storica e l'analisi dei trend temporali di mortalità dal 1933 al 2010 mostrano alcune criticità sanitarie in periodi specifici. L'elaborazione dei dati di mortalità per un arco temporale di circa 80 anni ha messo in evidenza la maggiore rilevanza di queste criticità con l'avvio dello sviluppo industriale.

    Three Total Petroleum Systems each consisting of one assessment unit have been identified in the Ghaba and Fahud Salt Basin Provinces of north-central Oman. One Total Petroleum System and corresponding assessment unit, the North Oman Huqf/?Q??Haushi(!) Total Petroleum System (201401) and Ghaba- Makarem Combined Structural Assessment Unit (20140101), were identified for the Ghaba Salt Basin Province (2014). In the Fahud Salt Basin Province, however, two overlapping Total Petroleum Systems (TPS) were recognized: (1) the North Oman Huqf?Shu?aiba(!) TPS (201601); Fahud-Huqf Combined Structural Assessment Unit (20160101), and (2) the middle Cretaceous Natih(!) TPS (201602); Natih-Fiqa Structural/Stratigraphic Assessment Unit (20160201). The boundary for each Total Petroleum System also defines the boundary of the corresponding assessment unit and includes all trap styles and hydrocarbon-producing reservoirs within the petroleum system. In both the Ghaba and Fahud Salt Basin Provinces, hydrocarbons were generated from several deeply buried source rocks within the Infracambrian Huqf Supergroup. One general ?North Oman Huqf? type oil is dominant in the Fahud Salt Basin. Oils in the Ghaba Salt Basin are linked to at least two distinct Huqf source-rock units based on oil geochemistry: a general North Oman Huqf-type oil source and a more dominant ?questionable unidentified source? or ?Q?-type Huqf oil source. These two Huqf-sourced oils are commonly found as admixtures in reservoirs throughout northcentral Oman. Hydrocarbons generated from Huqf sources are produced from a variety of reservoir types and ages ranging from Precambrian to Cretaceous in both the Ghaba and Fahud Salt Basin Provinces. Clastic reservoirs of the Gharif and Al Khlata Formations, Haushi Group (middle Carboniferous to Lower Permian), dominate oil production in the Ghaba Salt Basin Province and form the basis for the Huqf/?Q??Haushi(!)

    AIM To correct the misclassification in registered gastric cancer incidence across Iranian provinces in cancer registry data. METHODS Gastric cancer data is extracted from Iranian annual of national cancer registration report 2008. A Bayesian method with beta prior is implemented to estimate the rate of misclassification in registering patient’s permanent residence in neighboring province. Each time two neighboring provinces with lower and higher than 100% expected coverage of cancer cases are selected to be entered in the model. The expected coverage of cancerous patient is reported by medical university of each province. It is assumed that some cancer cases from a province with a lower than 100% expected coverage are registered in their neighboring province with more than 100% expected coverage. RESULTS The condition was true for 21 provinces from a total of 30 provinces of Iran. It was estimated that 43% of gastric cancer cases of North and South Khorasan provinces in north-east of Iran was registered in Razavi Khorasan as the neighboring facilitate province; also 72% misclassification was estimated between Sistan and balochestan province and Razavi Khorasan. The misclassification rate was estimated to be 36% between West Azerbaijan province and East Azerbaijan province, 21% between Ardebil province and East Azerbaijan, 63% between Hormozgan province and Fars province, 8% between Chaharmahal and bakhtyari province and Isfahan province, 8% between Kogiloye and boyerahmad province and Isfahan, 43% Golestan province and Mazandaran province, 54% between Bushehr province and Khozestan province, 26% between Ilam province and Khuzestan province, 32% between Qazvin province and Tehran province (capital of Iran), 43% between Markazi province and Tehran, and 37% between Qom province and Tehran. CONCLUSION Policy makers should consider the regional misclassification in the time of programming for cancer control, prevention and resource allocation. PMID:28255430

    The Kivu Province is located at the junction between the well-defined Ruzizi Valley to the south and the Lake Amin Trough to the north. In this zone, the Rift Valley is characterized by the highest uplift and by complex dislocations of the crust, accompanied by the most intensive volcanism of the East African Rift System. In this paper, we show the recent state of the seismic activity of this zone in connection with the seismic activity generated by the volcanoes Nyiragongo and Nyamuragira. The pattern of cumulative energy release by these volcanoes shows a steplike increase that is believed to be a precursor of volcanic eruptions.

    The perceived responsiveness of a healthcare system reflects its ability to satisfy reasonable expectations of the public with respect to non-medical services. Recently, there has been increasing attention paid to responsiveness in evaluating the performance of a healthcare system in a variety of service settings. However, the factors that affect the responsiveness have been inconclusive so far and measures of improved responsiveness have not always thoroughly considered the factors. The aim of this study was to evaluate both the responsiveness of the healthcare system in Jiangsu Province, China, the factors that influence responsiveness and the measures of improved responsiveness considering it, as determined by a responsiveness survey. A multistage, stratified random sampling method was used to select 1938 adult residents of Jiangsu Province in 2011. Face-to-face interviews were conducted using a self-designed questionnaire modeled on the World Health Organization proposal. The final analysis was based on 1783 (92%) valid questionnaires. Canonical correlation analysis was used to assess the factors that affect responsiveness. The average score of all responsiveness-related domains in the surveyed healthcare system was satisfactory (7.50 out of a maximum 10.0). The two highest scoring domains were dignity and confidentiality, and the two lowest scoring domains choice and prompt attention. The factors affecting responsiveness were age, regional economic development level, and geographic area (urban vs. rural). The responsiveness regarding basic amenities was rated worse by the elderly than by younger respondents. Responsiveness ranked better by those with a poorer economic status. Choice in cities was better than in rural regions. The responsiveness of the Jiangsu healthcare system was considered to be satisfactory but could be improved by offering greater choice and providing more prompt attention. Perceptions of healthcare system responsiveness differ with age

    This report presents results on the occurrence and biogeochemistry of unusual plant species, and of their supporting sediment, in an undisturbed volcanogenic massive sulfide deposit in the Tintina Gold Province (see fig. 1 of Editors’ Preface and Overview). The extraordinary plant assemblage found growing in the acidic metal-rich waters that drain the area is composed predominantly of bryophytes (liverworts and mosses). Ferricrete-cemented silty alluvial sediments within seeps and streams are covered with the liverwort Gymnocolea inflata, whereas the mosses Polytrichum commune and P. juniperinum inhabit the area adjacent to the water and within the splash zone. Both the liverwort-encrusted sediment and Polytrichum thalli have high concentrations of major- and trace-metal cations (for example, Al, As, Cu, Fe, Hg, La, Mn, Pb, and Zn). Soils in the area do not reflect the geochemical signature of the mineral deposit, and we suspect that they are most influenced by the chemistry of airborne dust (aeolian material) derived from outside the area.

    Through the analysis of the development activities and the ecological environment in coastal of Hebei Province, China, an index system for evaluating the ecological environment effect, composed of 28 indices, was set up by the pressure, state and response subsystems. Using the comprehensive index evaluation method, the integrated effects of ecological environment index (EI) was calculated and its grading criterion was founded. The results showed that the ecological environment effect of Hebei Province coastal development varied from being relatively small, normal and then relatively large from 1984 to 2010, and its acceptance degree evolved from being acceptable to being unacceptable. Because the resource and environment pressures caused by coastal development were serious and a delay existed in the state relative to the response, the improvement of various measures in the response subsystem did not show a positive effect on the state, and the environmental quality of ocean showed a degrading trend. Due to the differences in coastal development pattern and strength, the ecological environment effect of development activities showed some spatial differences. The ecological environment effect of Qinhuangdao coastal development was the minimum, followed by Cangzhou and Tangshan. Cangzhou and Tangshan had reached unacceptable levels and needed to further strengthen the restoration and protection of ecological environment.

    Different hypotheses exist on the origin of native copper mineralization in the Paraná volcanic province that invoke magmatic, late magmatic, or hydrothermal events. The average copper content in the host basalts is 200 ppm. Native copper occurs as dendrites in cooling joints, fractures, and cavities within amygdaloidal crusts. Cuprite, tenorite, chrysocolla, malachite, and azurite occur in breccias at the top of the lava flows. Chemical analyses, X-ray diffraction, Raman spectrometry, electron microprobe analyses, LA-ICP-MS, and Cu isotope analyses were used to evaluate the origin of native copper in the volcanic province. Copper contents in magnetite of the host basalt are close to 1 wt.%, whereas clinopyroxene contains up to 0.04 wt.% Cu. Cretaceous hydrothermal alteration of magnetite and clinopyroxene released copper to generate hydrothermal copper mineralization. The isotopic composition of the native copper in the Paraná volcanic province varies from -0.9‰ in the southeastern portion (Rio Grande do Sul state) to 1.9‰ in the central portion (Paraná state) of the province. This study supports a hydrothermal origin followed by supergene enrichment for native copper in the Paraná volcanic province.

    The magnetic anomalies of the high arctic are dominated by a large domain (1000 x 1700 km; the High Arctic Magnetic High, HAMH) consisting of numerous high-amplitude magnetic high ridges with a complex set of orientations and by other smaller, but still fundamentally highly magnetic, domains. The magnetic potential anomaly field (also known as pseudogravity) of the HAMH shows a single large intensity high and underscores the crustal-scale thickness of this geophysical feature (which also forms a prominent anomaly on satellite magnetic maps). The seafloor morphology of this region includes the complex linear trends of the Alpha and Mendeleev ridges, but the magnetic expression of this domain extends beyond the complex bathymetry to include areas where Canada Basin sediments have covered the complex basement topography. The calculated magnetic effect of the bathymetric ridges matches some of the observed magnetic anomalies, but not others. We have analyzed and modeled the distinctive HAMH and other smaller magnetic high domains to generate estimates of their volume and to characterize the directionality of their component features. Complimentary processing and modeling of high arctic gravity anomalies allows characterization of the density component of these geophysical features. Spatially, the HAMH encompasses the Alpha and Mendeleev "ridges," that are considered to represent a major mafic igneous province. The term "Alpha-Mendeleev Large Igneous Province" is given to a domain mapped by tracing magnetic anomalies in a recent map published by AAPG (Grantz and others, 2009). On this map the province is described as "alkali basalt with ages between 120 and 90 Ma". New seismic and bathymetric data, collected as part of on-going research efforts for definition of extended continental shelf, are revealing new details about the Alpha ridge. One interesting development is the possible identification of a supervolcano that may represent a major locus of igneous activity. In

    Previous research has shown a high rate and a unique pattern of suicide in China. We aim to present the current suicide rates and patterns in the Yunnan province, a multi-ethnic region in Southwestern China. This is a descriptive study based on the 3rd Chinese national mortality survey. We reported the suicide rates by sex, 5-year age group, region (urban or rural), and minority group from 2004 to 2005 in the Yunnan province. We estimated a mean annual suicide rate of 19.82 per 100,000 and a total of 8751 suicide deaths per year. Sex-specific rate estimates were 21.09 per 100,000 and 18.46 per 100,000 for males and females, respectively. The male/female ratio was 1.14. Region-specific rate estimates were 20.60 per 100,000 and 19.18 per 100,000 for rural and urban regions, respectively. The rural-to-urban ratio was 1.07. Suicide accounted for 4.83% of all deaths in the Yunnan province and represented the fifth leading cause of death. In minority groups, the highest suicide rates were found in the Li su minority (50.75 per 100,000), the Jing po minority (36.38 per 100,000), the Meng gu minority (32.65 per 100,000) and the Miao minority (30.75 per 100,000). The lowest rates were found in the Hui minority (0.96 per 100,000) and the Ha ni minority (1.64 per 100,000). The suicide characteristics of this multi-ethnic region of China are different from those of the rest of China and the world, which indicates that the development of a special intervention strategy in multi-ethnic areas for suicide prevention is needed.

    Based on the long-term located observation of forest ecosystem, and by using the 2006 forest resources inventory data of Liaoning Province and the forest industry standard of the People's Republic of China( LY/T 1721-2008, specification for assessment of forest ecosystem services in China), an evaluation was made on the material quantity and services value of main forest ecosystems in fourteen cities of Liaoning Province. In this province, the forest ecosystem services value supplied by water storage, soil conservation, C fixation, O2 release, nutrients accumulation, environment purification, biodiversity conservation, and forest recreation in 2006 was 2591.72 x 10(8) yuan, which was 8.54 times of the forestry production value and 28.02% in the GDP of the province. The services value of water storage, biodiversity conservation, C fixation, and O2 release occupied 79.09% of the total, being the main forest ecosystem services in the province. Economic forest and shrub had smaller per unit services value but larger area, and hence, their ecosystem services value should not be ignored. Abies fargesii forest, Phellodendron amurense forest, Juglans mandshurica forest, and Fraxinus mandshurica forest were the representative zonal vegetations in Liaoning Province, which had high value in biodiversity conservation. Under the effects of climate and other factors, the forest area and forest quality in west Liaoning were lower than those in east Liaoning.

    The Caucasus lies between the Black Sea and the Sea of Azov on the west and the Caspian Sea on the east. The main morphological elements of the Caucasus are the mountain ranges of Greater and Lesser Caucasus, which are divided by the Rioni (Colchis) and Kura intermontane troughs and the pre-Caucasian plain and Araks Depression. The tectonic features of the region result from its position between the Eurasian and Africa-Arabian plates. Two tectonic units of the highest order are distinguished within its limits, the young Scythian platform in the north and the Alpine fold belt in the south. Oil and gas deposits have been found only in the lowlands of the Caucasus, in the pre-Caucasian foreland, and within the Transcaucasian intermontane depressions. The North Caucasian province is made up of the Scythian platform and the marginal troughs of the Alpine Greater Caucasus. Oil and gas accumulations occur at all levels within the sedimentary cover from Triassic the Neogene. In the South Caspian oil and gas subprovince, oil and gas occurs within reservoirs range in age from Late Cretaceous to the Apsheronian stage of the Neogene. The Black Sea subprovince comprises the northwestern part of the sea and the western part of Georgia. The bulk of the explored oil reserves lies within the Neogene and Upper Cretaceous units. The potential in this region is associated with Jurassic terrigenous, Upper Cretaceous carbonate, and Paleogene terrigenous sediments.

  10. Tsunami damage in Aceh Province, Sumatra

    The island of Sumatra suffered from both the rumblings of the submarine earthquake and the tsunamis that were generated on December 26, 2004. Within minutes of the quake, the sea surged ashore, bringing destruction to the coasts of northern Sumatra. This pair of natural-color images from Landsat 7's Enhanced Thematic Mapper Plus (ETM+) instrument shows a small area along the Sumatran coast in Aceh province where the tsunami smashed its way ashore. In this region, the wave cut a swath of near-total destruction 1.5 kilometers (roughly one mile) in most places, but penetrating farther in many others. Some of these deeper paths of destruction can be seen especially dramatically in the larger-area ETM+ images linked to above. (North is up in these larger images.) ETM+ collects data at roughly 30 meter resolution, complimenting sensors like NASA's MODIS (onboard both Terra and Aqua satellites) which observed this area at 250-meter resolution to give a wide view and ultra-high-resolution sensors like Space Imaging's IKONOS, which observed the same region at 4-meter resolution to give a detailed, smaller-area view.

    The purpose of the U.S. Geological Survey (USGS) National Oil and Gas Assessment is to develop geology-based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States, focusing on the distribution, quantity, and availability of oil and natural gas resources. The USGS has completed an assessment of the undiscovered, technically recoverable oil and gas resources in western Oregon and Washington (USGS Western Oregon and Washington Province 5004). The province includes all of Oregon and Washington north of the Klamath Mountains and west of the crest of the Cascade Range, and extends offshore to the 3-mi limit of State waters on the west and to the International Boundary in the Straits of Juan de Fuca and Canada on the north. It measures about 450 mi north-south and 50 to 160 mi east-west, encompassing more than 51,000 mi2. The assessment of the Western Oregon and Washington Province is geology based and used the total petroleum system (TPS) concept. The geologic elements of a TPS include hydrocarbon source rocks (source rock maturation and hydrocarbon generation and migration), reservoir rocks (quality and distribution), and traps for hydrocarbon accumulation. Using these geologic criteria, two conventional and one unconventional (continuous) total petroleum systems were defined, with one assessment unit (AU) in each TPS: (1) the Cretaceous-Tertiary Composite TPS and the Western Oregon and Washington Conventional Gas AU, (2) the Tertiary Marine TPS and the Tertiary-Marine Gas AU, and (3) the Tertiary Coalbed Gas TPS and the Eocene Coalbed Gas AU, in which a cell-based methodology was used to estimate coalbed-gas resources.

    On July 8, 2003, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor acquired satellite imagery of a 60-kilometer-wide swath covering a portion of the Bonnifield mining district within the southernmost part of the Tintina Gold Province, Alaska, under unusually favorable conditions of minimal cloud and snow cover. Although rocks from more than eight different lithotectonic terranes are exposed within the extended swath of data, we focus on volcanogenic massive sulfides (VMS) and porphyry deposits within the Yukon-Tanana terrane (YTT), the largest Mesozoic accretionary terrane exposed between the Denali fault system to the south of Fairbanks and the Tintina fault system to the north of Fairbanks. Comparison of thermal-infrared region (TIR) decorrelation stretch data to available geologic maps indicates that rocks from the YTT contain a wide range of rock types ranging in composition from mafic metavolcanic rocks to felsic rock types such as metarhyolites, pelitic schists, and quartzites. The nine-band ASTER visible-near-infrared region--short-wave infrared region (VNIR-SWIR) reflectance data and spectral matched-filter processing were used to map hydrothermal alteration patterns associated with VMS and porphyry deposit types. In particular, smectite, kaolinite, opaline silica, jarosite and (or) other ferric iron minerals defined narrow (less than 250-meter diameter) zonal patterns around Red Mountain and other potential VMS targets. Using ASTER we identified some of the known mineral deposits in the region, as well as mineralogically similar targets that may represent potential undiscovered deposits. Some known deposits were not identified and may have been obscured by vegetation or snow cover or were too small to be resolved.

    We imaged the crust structure beneath Jilin Province and Liaoning Province in China with fundamental mode Rayleigh waves recorded by 60 broadband stations deployed in the region. Surface-wave empirical Green's functions were retrieved from cross-correlations of inter-station data and phase velocity dispersions were measured using a frequency-time analysis method. Dispersion measurements were then utilized to construct 2D phase velocity maps for periods between 5 and 35 s. Subsequently, the phase-dispersion curves extracted from each cell of the 2D phase velocity maps were inverted to determine the 3D shear wave velocity structures of the crust. The phase velocity maps at different periods reflected the average velocity structures corresponding to different depth ranges. The maps in short periods, in particular, were in excellent agreement with known geological features of the surface. In addition to imaging shear wave velocity structures of the volcanoes, we show that obvious low-velocity anomalies imaged in the Changbaishan-Tianchi Volcano, the Longgang-Jinlongdingzi Volcano, and the system of the Dunmi Fault crossing the Jingbohu Volcano, all of which may be due to geothermal anomalies.

    In Thailand nearly 1000 public health laboratories serve 65 million people. A qualified indicator of a good quality laboratory is Thailand Medical Technology Council certification. Consequently, Chiang Rai Regional Medical Sciences Center established a development program for laboratory certification for 29 laboratories in the province. This paper seeks to examine this issue. The goal was to improve laboratory service quality by voluntary participation, peer review, training and compliance with standards. The program consisted of specific activities. Training and workshops to update laboratory staffs' quality management knowledge were organized. Staff in each laboratory performed a self-assessment using a standard check-list to evaluate ten laboratory management areas. Chiang Rai Regional Medical Sciences Center staff supported the distribution of quality materials and documents. They provided calibration services for laboratory equipment. Peer groups performed an internal audit and successful laboratories received Thailand Medical Technology Council certification. By December 2007, eight of the 29 laboratories had improved quality sufficiently to be certified. Factors that influenced laboratories' readiness for quality improvement included the number of staff, their knowledge, budget and staff commitment to the process. Moreover, the support of each hospital's laboratory working group or network was essential for success. There was no clear policy for supporting the program. Laboratories voluntarily conducted quality management using existing resources. A bottom-up approach to this kind of project can be difficult to accomplish. Laboratory professionals can work together to illustrate and highlight outcomes for top-level health officials. A top-down, practical approach would be much less difficult to implement. Quality certification is a critical step for laboratory staff, which also encourages them to aspire to international quality standards like ISO. The

    Recently compiled data on the state of stress have been used to define stress provinces in the conterminous United States in which the orientation and relative magnitude of the horizontal principal stresses are fairly uniform. The observed patterns of stress constrain mechanisms for generating intraplate lithospheric stresses. Coupled with new information on geologic structure and tectonism in seismically active areas of the Midcontinent and East, these data help to define some characteristics common to these areas and to identify key questions regarding why certain faults seem to be seismically active.

    To analyze the surveillance data of malaria in Tengchong County of Yunnan Province in 2013, so as to provide the evidence for carrying out the malaria elimination in the future. The data of epidemic situation and surveillance of malaria in Tengchong County in 2013 were collected and analyzed for the prevalence state as well as and the monitoring indicators including the blood examination of fever patients of unknown origin, initiative detection of cases, under-reporting survey, sentinel surveillance and species and density investigation of Anopheles mosquitoes. Totally 138 malaria cases were reported in Tengchong County in 2013, among which 118 cases were infected with Plasmodium vivax and 20 cases with P. falciparum, and all the reported cases were imported. The completion rates of blood examinations, case reports and case investigations all reached 100%. A total of 57 cases were involved in initiative detection, but no positive cases were found. The twice under-reporting of malaria case surveys were conducted and 1 case had been under-reported. The sentinel surveillance was carried out both in the domestic and overseas sites at the same time to detect the suspected malaria cases, 172 cases were screened totally, and 15 ones were detected as positives. Totally 528 returnees were screened, and there were no positive case found. A. sinensis and A. liangshanensis were the dominant species, followed by A. minimus, A. maculatus and others. The malaria epidemic situation is stable in Tengchong County in 2013, and all the work in surveillance has been conducted successfully, but there still exist some difficulties in the process of malaria elimination. The local health departments should further strengthen the surveillance on imported cases and the management on migrant population as well as the capability building for health workers in malaria control in the future.

    An investigation of the geohydrologic system in the Ozark Plateaus province (index map and Fenneman, 1938) has been made as part of the Central Midwest Regional Aquifer System Analysis (Jorgensen and Signor, 1981), a major study of the regional aquifer system in parts of 10 States. The study is one of several by the U.S. Geological Survey that are designed to increase knowledge of the flow regime and geohydrologic properties of regional aquifer systems in the United States. Because a large quantity of fresh ground water is available in aquifers underlying the Ozark Plateaus province, a subregional project has been established to study the geohydrologic units of this area in more detail than is practical in the regional study. The stratigraphic and geologic relationships among the primary geohydrologic units in and adjacent to the Ozark Plateaus is depicted in this atlas (Chapter A). This is the first of a series of chapters (A-H) that includes maps of the altitude of the top, thickness, potentiometric surface, and percentage-of-shale content of individual geohydrologic units.

    The Sirte (Sirt) Basin province ranks 13th among the world?s petroleum provinces, having known reserves of 43.1 bil-lion barrels of oil equivalent (36.7 billion barrels of oil, 37.7 tril-lion cubic feet of gas, 0.1 billion barrels of natural gas liquids). It includes an area about the size of the Williston Basin of the north-ern United States and southern Canada (?490,000 square kilome-ters). The province contains one dominant total petroleum system, the Sirte-Zelten, based on geochemical data. The Upper Cretaceous Sirte Shale is the primary hydrocarbon source bed. Reservoirs range in rock type and age from fractured Precam-brian basement, clastic reservoirs in the Cambrian-Ordovician Gargaf sandstones, and Lower Cretaceous Nubian (Sarir) Sand-stone to Paleocene Zelten Formation and Eocene carbonates commonly in the form of bioherms. More than 23 large oil fields (>100 million barrels of oil equivalent) and 16 giant oil fields (>500 million barrels of oil equivalent) occur in the province. Abstract 1 Production from both clastic and carbonate onshore reservoirs is associated with well-defined horst blocks related to a triple junc-tion with three arms?an eastern Sarir arm, a northern Sirte arm, and a southwestern Tibesti arm. Stratigraphic traps in combina-tion with these horsts in the Sarir arm are shown as giant fields (for example, Messla and Sarir fields in the southeastern portion of the province). Significant potential is identified in areas marginal to the horsts, in the deeper grabens and in the offshore area. Four assessment units are defined in the Sirte Basin prov-ince, two reflecting established clastic and carbonate reservoir areas and two defined as hypothetical units. Of the latter, one is offshore in water depths greater than 200 meters, and the other is onshore where clastic units, mainly of Mesozoic age, may be res-ervoirs for laterally migrating hydrocarbons that were generated in the deep-graben areas. The Sirte Basin reflects significant rifting

    2003-09-01

    We present new paleomagnetic and multi-model stereo photogrammetry data from lava sequences in the West Greenland part of the North Atlantic igneous province (NAIP). The joint analyses of paleomagnetic and photogrammetric data yield a well-defined paleomagnetic pole located at Lat=73.6°N, Long=160.5°E ( N=44, α95=6.2°, K=13.1; age ˜61-55 Ma), which is statistically indistinguishable from a pole recently obtained for the Eurasian part of the NAIP on Faroe Islands [Riisager et al., Earth Planet. Sci. Lett. 201 (2002) 261-276]. Combining the two datasets we obtain a joint NAIP paleomagnetic pole in Greenland coordinates: Lat=71.1°N, Long=161.1°E ( N=87, α95=4.3°, K=13.6; age ˜61-54 Ma). The results presented here represent the first study in which photogrammetry profiles were photographed at the exact same locations where paleomagnetic fieldwork was carried out, and a direct flow-to-flow comparison of the two datasets is possible. Photogrammetry is shown to be particularly useful because of (i) highly precise dip/strike measurements and (ii) detailed 'field observations' that can be made in the laboratory. Highly precise determination of the structural attitude of well-exposed Kanisut Mb lava sequences demonstrates that their apparently reliable in-field dip/strike measurements typically are up to ˜6° wrong. Erroneous dip/strike readings are particularly problematic as they offset paleomagnetic poles without affecting their confidence limits. Perhaps more important for large igneous provinces is the recognition of a variable temporal relationship between consecutive lava flows. We demonstrate how correct interpretation of paleosecular variation, facilitated by the detailed photogrammetry analysis, is crucial for the rapidly emplaced Vaigat Formation lavas. Inaccurate tectonic correction, non-averaged paleosecular variation and unrecognized excursional directions may, perhaps, explain why coeval paleomagnetic poles from large igneous provinces are often

    The recent discovery of major oil resources on Alaska's North Slope has rekindled interest in the petroleum possibilities of the Yukon-Koyukuk province, a vast tract of Cretaceous rocks stretching along the west coast of Alaska from the Brooks Range to the Yukon delta. Attention was first focused on this region in the early 1950's, after oil and gas were discovered in the Cretaceous of the North Slope by the U.S. Navy. The presence of similar Cretaceous strata in the Yukon-Koyukuk province and the possibility that some of the broad alluviated lowlands within the province might be underlain by Tertiary basins were pointed out by Gryc and others (1951) and Payne (1955). Between 1954 and 1961 large parts of the province were reconnoitered by oil company surface parties and a small amount of geophysical work was carried out in the Nulato-Kateel and Bethel areas. The explorational activity culminated in 1960-61 with the drilling of two deep tests, a 12,000-foot hole near Nulato on the Yukon River and a 15,000-foot hole at Napatuk Creek in the Yukon-Kuskokwim Coastal Lowland. Apparently neither test revealed oil shows or favorable reservoir rocks, as exploration and leasing activity in the province declined sharply thereafter.

    Urinary stone diseases in the Khouzestan province (southwest Iran) are growing in number and it required extensive studies on various factors of the urinary stones formation in this province. In this research, in addition to distribution of urinary stones in different areas of province, the role of bioenvironmental (race), climate (temperature) and geology (water hardness) factors in urinary stones diversity has been studied. Mineralogical studied using X-ray diffraction showed that uricite and whewellite are the most frequency mineral phases. Struvite, Cystine, hydroxyapatite, weddellite, and Niahite can be observed as urinary stones, too. These data show that the urinary stone in the Khouzestan province can divide into 7 groups: calcium oxalate, phosphate, calcium oxalate/ phosphate, Urate, Urate/calcium, Urate/calcium oxalate/phosphate, Cystine/calcium oxalate. Also the results which attained from temperature effect investigation on the mineralogy of urinary stones, confirms that from Mediterranean sub-humid climates (northeastern area) to warm and dry climates (south and southwest area), calcium oxalate stones and urate stones concentration decreases and increases respectively. Comparison of data related to the drinking water hardness and mineralogy of urinary stones in different areas of Khouzestan province show that the combination of drinking water (especially water hardness) affects mineralogy of urinary stones in some areas (such az Ramhormoz and Hendijan). Finally, the data suggest that frequency of calcium oxalate in women is more than that of men. Moreover, there is direct relationship between the age (>45 years) and the increase in frequency of Urate minerals.

    By the methods of emergy analysis, this paper studied the emergy flow in the ecological-economic system in Liaoning Province in 1990-2005, and the relationships between the environmental stress caused by resources' input, output and consumption and the sustainable development of the Province. The results showed that in Liaoning Province, the non-renewable resources occupied over 74% of the total consumed emergy, and the realistic population in 2005 was 3.26 times higher than the supportable population. In 1990-2005, the emergy yield ratio decreased from 65.40 to 10.13, emergy loading ratio increased from 2.72 to 7.18, and emergy sustainable index decreased from 24.03 to 1.41. The rapid economic growth in Liaoning Province was chiefly supported by the consumption of vast non-renewable resources, which caused the pressure of economic development on ecosystem getting more and more intense, the economic development increasingly depending on exogenous resources, and the sustainable development of Liaoning ecological-economic system having a continuing decrease. To realize the sustainable development in Liaoning Province, the principles of reduction, reutilization and recycling should be taken as the guidelines for promoting the reuse of wastes and the closed fine circulation of resources to minimize the discharge of wastes.

    According to the age of major reservoirs, hydrocarbon occurrences in Libya and adjacent areas can be grouped into six major systems which, according to their geographic locations, can be classified into two major hydrocarbon provinces: (1) Sirte-Pelagian basins province, with major reservoirs ranging from middle-late Mesozoic to early Tertiary, and (2) Murzog-Ghadames basins province, with major reservoirs ranging from early Paleozoic to early Mesozoic. In the Sirte-Pelagian basins province, hydrocarbons have been trapped in structural highs or in stratigraphic wedge-out against structural highs and in carbonate buildups. Here, hydrocarbon generation is characterized by the combined effect of abundant structural relief and reservoir development in the same hydrocarbon systems of the same age, providing an excellent example of hydrocarbon traps in sedimentary basins that have undergone extensive tensional fracturing in a shallow marine environment. In the Murzog-Ghadames basins province, hydrocarbons have been trapped mainly in structural highs controlled by paleostructural trends as basement arches which acted as focal points for oil migration and accumulation.

    The U.S. Geological Survey recently assessed the potential for natural gas resources in the Middle Devonian Marcellus Shale of the Appalachian Basin Province. The Marcellus Shale was assessed as a continuous gas accumulation using a methodology identical to that used in the assessment of shale and other continuous-type assessment units throughout the United States. This preliminary report provides some additional geologic information used in the Marcellus Shale assessment. The Appalachian Basin Province encompasses rocks of the Paleozoic passive margins, the foreland basins, and fold and thrust belts formed during several episodes in the Paleozoic. The Marcellus Shale is one of many marine shales deposited in the area that is now encompassed by the Appalachian Basin Province.

    The Trans-Hudson Orogen (THO) in the north central United States represents a major suturing event between the Wyoming and Superior Archean provinces. It is bounded to the south by the NE-SW striking Yavapai province, which was accreted along the southeastern margin of North America between 1.71 and 1.68 Ga and was one of a series of major collisional events responsible for the assembly of Laurentia. In this study, PdS teleseismic receiver functions were used to investigate the deep crustal structure associated with these collisions. Using data from over 800 broadband seismic stations distributed throughout the Great Plains/Midcontinent region, we calculated 0.5 Hz receiver functions using 245 M > 6.0 teleseismic events. The receiver functions were then CCP (common conversion point) stacked to create a 3D image volume. Profiles through this image volume show evidence of crustal scale thrusting of the Wyoming province in the west over the Superior province in the east and a relic subduction zone associated with the Yavapai-Superior boundary. We also performed a density analysis of the region using relative amplitude of the 2p1s and 0p1s receiver function phases from 233 stations. These data indicate a relatively low Moho density contrast throughout the THO and northern Yavapai Province associated with a region of thickened crust (>50 km), which we interpret to be evidence of a dense lower crustal layer that is the result of mafic underplating.

    Zhejiang Province in China has promoted a new family planning program since April 1993. The program stresses delayed marriage and childbearing, fewer and healthier births, modernization of family life, and prosperity through hard work. The people are receptive to the new program out of a desire for an improved standard of living. The objective is to build small, modern families who 1) practice deferred marriage and childbearing; 2) voluntarily practice family planning and have no unplanned births; 3) practice avoidance of consanguineous marriage, become sterilized if a carrier of a hereditary disease of chromosomal abnormality, and use premarital education and counseling and proper prenatal care; 4) uphold the laws and maintain discipline in action to avoid criminal behavior; 5) establish families that respect the old, care for children, and help their neighbors; 6) complete 9 years of compulsory education; and 7) create well being through hard work. The program is compatible with the strategy of the "three stresses" and an integrated approach. IEC and service provision are important components in program implementation. The target population are the masses and grassroots cadres, particularly those in the childbearing ages. IEC will be directed in different ways to different groups. Those aged 18-35 years will receive education. Face to face interaction with family planning workers and lectures will be directed to grassroots cadres. The mass media will be employed to reach the masses. The messages will include information and persuasion to adopt new families, accept family planning regulations, and learn about contraceptive use, healthy births and childrearing, education, health care, sex education, and income generation skills. Classes will be conducted for groups, such as teenagers, unmarried youth, pregnant women, and lactating women. Priority will be given to couples that accept the certificates for one child; favoritism will be granted for allocation of

    Using fertility survey data from the 1980s for registered Han peasant couples in Hebei Province, this study examines whether China's family planning policy reflects couples' voluntary compliance with policy regulations, their coercion by means of government sanctions, or a combination of both. Three family planning regulations are considered: birth-quota status, contraceptive use, and length of prior birth interval. The results of the study provide support for both compliance and sanction perspectives and suggest that by the late 1980s, the state was less willing than it had been previously to negotiate with couples who had had three children. Evidence is found of cooperation between couples and the state to ensure that each family had at least one son.

    This analysis of the sanitary policies enforced in the province of Buenos Aires by Domingo Alfredo Mercante--Juan Domingo Perón's right-hand man--focuses on one of his most fascinating efforts: the eradication of hydatidosis. In exploring an issue largely forgotten by historiography, the article describes how the Mercante administration (1946-52) used statistical, socioeconomic, and symbolic legitimization to place hydatidosis on the State agenda. The administration's strategies are also pinpointed: the passing of regulatory laws against this endemic disease; the creation of specific state anti-hydatidosis institutions; the creation of space for information and for interdisciplinary, interministerial, and even supranational education aimed at achieving greater knowledge of the disease and at the exchange of experiences; and, lastly, the definition of initiatives focused on relief, treatment, and prevention in animals and people.

    Toxoplasma gondii infections are prevalent in animals and humans worldwide. In the present investigation, the seroprevalence of T. gondii in goats was investigated in Hunan province, subtropical China between March 2014 and December 2015. A total of 1,028 serum samples collected from 14 administrative regions of Hunan province were evaluated by the indirect hemagglutination test (IHAT) for the detection of specific antibodies. Antibodies to T. gondii were detected in 124 serum samples (12%). The T. gondii seroprevalence ranged from 1.7% to 19% among different regions in subtropical China, and the differences were statistically significant (p < 0.01). The results of the present survey indicated that T. gondii infection is prevalent in goats in Hunan, which poses a potential risk for human infection with T. gondii in this province. PMID:27762212

    This is a thermodynamic analysis of the Province of Ravenna (Italy) and its districts (Ravenna, Faenza and Lugo) and an evaluation of entropy waste production based on a balance sheet of greenhouse gases. The method used is energy analysis. The results show that the Province and Ravenna are characterized by a heavy exploitation of local non renewable resources, Faenza strikes a good balance between economic development and environment conservation and Lugo is less sustainable than the others. The greenhouse gas balance shows that the Province emits 10.5 times the quantity of greenhouse gases that it adsorbs and that the emissions reduction is required in the energy sector, which is responsible for 92% of the total.

    Abstract The Mycetophagidae (hairy fungus beetles) of the Maritime Provinces of Canada are surveyed. Seven species in the genera Mycetophagus, Litargus, and Typhaea are found in the region. Six new provincial records are reported including Mycetophagus punctatus and Mycetophagus flexuosus, whichare newly recorded in the Maritime Provinces. The distribution of all species is mapped, colour habitus photographs of all species are figured, and an identification key to species is provided. The discussion notes that four of the species found in the region are apparently rare, possibly due to the history of forest management practices in the region; a situation similar to that of a significant proportion of other saproxylic beetles found in the Maritime Provinces.

    The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas potential of the Late Cretaceous Navarro and Taylor Groups in the Western Gulf Province in Texas (USGS Province 5047). The Navarro and Taylor Groups have moderate potential for undiscovered oil resources and good potential for undiscovered gas resources. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define one total petroleum system and five assessment units. Five assessment units were quantitatively assessed for undiscovered oil and gas resources.

    The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The U.S. Geological Survey (USGS) recently completed an assessment of the undiscovered oil and gas potential of the Wind River Basin Province which encompasses about 4.7 million acres in central Wyoming. The assessment is based on the geologic elements of each total petroleum system (TPS) defined in the province, including hydrocarbon source rocks (source-rock maturation, hydrocarbon generation, and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). Using this geologic framework, the USGS defined three TPSs: (1) Phosphoria TPS, (2) Cretaceous-Tertiary TPS, and (3) Waltman TPS. Within these systems, 12 Assessment Units (AU) were defined and undiscovered oil and gas resources were quantitatively estimated within 10 of the 12 AUs.

  17. State of stress in the conterminous United States

    Inferring principal stress directions from geologic data, focal mechanisms, and in situ stress measurements, we have prepared a map of principal horizontal stress orientations for the conterminous United States. Stress provinces with linear dimensions which range between 100 and 2000 km were defined on the basis of the directions and relative magnitude of principal stresses. Within a given province, stress orientations appear quite uniform (usually within the estimated range of accuracy of the different methods used to determine stress). Available data on the transition in stress direction between the different stress provinces indicate that these transitions can be abrupt, occurring over <75 km in places. In the western United States, a region of active tectonism characterized by high levels of seismicity and generally high heat flow, the stress pattern is complex, but numerous stress provinces can be well delineated. Despite relative tectonic quiescence in the eastern and central United States, a major variation in principal stress orientation is apparent between the Atlantic Coast and midcontinent areas. Most of the eastern United States is marked by predominantly compressional tectonism (combined thrust and strike slip faulting), whereas much of the region west of the southern Great Plains is characterized by predominantly extensional tectonism (combined normal and strike slip faulting). Deformation along the San Andreas fault and in parts of the Sierra Nevada is nearly pure strike slip. Exceptions to this general pattern include areas of compressional tectonics in the western United States (the Pacific Northwest, the Colorado Plateau interior, and the Big Bend segment of the San Andreas fault) and the normal growth faulting along the Gulf Coastal Plain. Sources of stress are constrained not only by the orientation and relative magnitude of the stresses within a given province but also by the manner of transition of the stress field from one province to another

    Chagas disease is the principal zoonosis of the Province of Jujuy where it represents a major public health problem. In this paper the results of a serological screening of T. cruzi infection carried out in the Province of Jujuy are analyzed to determine the general prevalence, age and geographic distribution, sex ratio, prevalence in foreign population and their relation with migratory process. In every individual (N = 16482) indirect hemagglutination (IHA) and immunofluorescence (TIF) tests have been carried out. In 5879 of them the birth place in the territory of the Province and the number of foreign individuals (313, all Bolivians) were confirmed. Based on these data the individuals were grouped according to: a) the four geographical regions of the Province located at different altitude levels, Puna, Quebrada, Valle and Ramal; b) towns placed on or away from the main routes of communication of the Province. For the statistical analysis the X2 and Z tests were employed. The results show that: 1) the general prevalence was of 11.50%; 2) no differences existed between the sexes: 3) the region with the highest prevalence was the Valley (12.84%) followed by Ramal (10.43%), Quebrada (8.53%) and Puna (2.98%); 4) differences of the serum prevalence can be observed between the residents on and away from the main routes of communication denoting the existence of a migratory effect in the distribution of chagasic infection; 5) prevalence differences exist between naturalized foreigns (39.30%) and Argentines (10.25%), data which strengthen the previous remark. Except for the general prevalence, there are no similar serological surveys which might allow us to establish relationships with our results of which the outstanding one is the influence of the migratory aspect upon the prevalence and distribution of T. cruzi in the Province of Jujuy.

    Shanxi province, located in the center of China, is the biggest coal base of China. There are five coal-forming periods in Shanxi province: Late Carboniferous (Taiyuan Formation), Early Permian (Shanxi Formation), Middle Jurassic (Datong Formation), Tertiary (Taxigou Formation), and Quaternary. Hundred and ten coal samples and a peat sample from Shanxi province were collected and the contents of 20 potentially hazardous trace elements (PHTEs) (As, B, Ba, Cd, Cl, Co, Cr, Cu, F, Hg, Mn, Mo, Ni, Pb, Sb, Se, Th, U, V and Zn) in these samples were determined by instrumental neutron activation analysis, atomic absorption spectrometry, cold-vapor atomic absorption spectrometry, ion chromatography spectrometry, and wet chemical analysis. The result shows that the brown coals are enriched in As, Ba, Cd, Cr, Cu, F and Zn compared with the bituminous coals and anthracite, whereas the bituminous coals are enriched in B, Cl, Hg, and the anthracite is enriched in Cl, Hg, U and V. A comparison with world averages and crustal abundances (Clarke values) shows that the Quaternary peat is highly enriched in As and Mo, Tertiary brown coals are highly enriched in Cd, Middle Jurassic coals, Early Permian coals and Late Carboniferous coals are enriched in Hg. According to the coal ranks, the bituminous coals are highly enriched in Hg, whereas Cd, F and Th show low enrichments, and the anthracite is also highly enriched in Hg and low enrichment in Th. The concentrations of Cd, F, Hg and Th in Shanxi coals are more than world arithmetic means of concentrations for the corresponding elements. Comparing with the United States coals, Shanxi coals show higher concentrations of Cd, Hg, Pb, Se and Th. Most of Shanxi coals contain lower concentrations of PHTEs. ?? 2004 Elsevier Ltd.

    Experience with China's 20% energy intensity improvement target during the 11th Five-Year Plan (FYP) (2006-2010) has shown the challenges of rapidly setting targets and implementing measures to meet them. For the 12th FYP (2011-2015), there is an urgent need for a more scientific methodology to allocate targets among the provinces and to track physical and economic indicators of energy and carbon saving progress. This report provides a sectoral methodology for allocating a national energy intensity target - expressed as percent change in energy per unit gross domestic product (GDP) - among China's provinces in the 12th FYP. Drawing on international experience - especially the European Union (EU) Triptych approach for allocating Kyoto carbon targets among EU member states - the methodology here makes important modifications to the EU approach to address an energy intensity rather than a CO{sub 2} emissions target, and for the wider variation in provincial energy and economic structure in China. The methodology combines top-down national target projections and bottom-up provincial and sectoral projections of energy and GDP to determine target allocation of energy intensity targets. Total primary energy consumption is separated into three end-use sectors - industrial, residential, and other energy. Sectoral indicators are used to differentiate the potential for energy saving among the provinces. This sectoral methodology is utilized to allocate provincial-level targets for a national target of 20% energy intensity improvement during the 12th FYP; the official target is determined by the National Development and Reform Commission. Energy and GDP projections used in the allocations were compared with other models, and several allocation scenarios were run to test sensitivity. The resulting allocations for the 12th FYP offer insight on past performance and offer somewhat different distributions of provincial targets compared to the 11th FYP. Recommendations for reporting

    Systematic geologic mapping of the near side of the Moon has provided the basis for defining and delineating the major geological provinces of the near side. From the nature of the provinces and their distribution patterns a general historical sequence evolves. Five main surface-shaping periods are recognized: (1) one of intense early impact cratering; (2) another, probably overlapping the first, during which the impact basins were formed; (3) a prolonged period of varied terra volcanism; (4) a short period of mare volcanism that resulted in filling of the multiring basins; and (5) a period of diminishing volcanic activity continuing up to the time of formation of the last ray craters. ?? 1972.

  3. Magmatic systems of large continental igneous province

    2014-05-01

    Large igneous provinces (LIPs) of the modern type are known from the middle Paleoproterozoic and have a great abundance in the Phanerozoic. The most researches considered their appearance with ascending of the mantle thermochemical superplumes which provided simultaneously eruption of the same type of lavas on the huge territories. Judging on presence among them different subprovinces, formation of concrete magmatic systems were linked with protuberances (secondary plumes) on the superplumes surfaces. We suggest that origin of such plumes was linked with local enrichment of upper part of the superplumes head beneath roofing by fluid components; it led to lowering of the plume material density and initiated ascending of the secondary plumes. As a result, their heads, where partial melting occurred, can reach the level of the upper crust as it follows from absence of lower-crustal rocks among xenoliths in basalts, although mantle xenoliths existed in them. Important feature of LIPs is presence of two major types of mafic lavas: (1) geochemical-enriched alkali Fe-Ti basalts and picrites, and (2) basalts of normal alkalinity (tholeiites) with different contents of TiO2. At that the first type of mafites are usually typical for lower parts of LIPs which initially developed as continental rifts, whereas the second type composed the upper part of the traps' cover. Magmatic systems of the LIPs are subdivided on three levels of different deep: (1) zones of magma generation, (2) areas of transitional magma chambers where large often layered intrusive bodies are formed, and (3) areas on surface where lava eruptions and subvolcanic intrusions occurred. All these levels are linked by feeder dykes. The least known element of the system is area of magma generation, and, especially, composition of melting substratum. Important information about it is contained in aforementioned mantle xenoliths in alkali basalts and basanites. They practically everywhere are represented by two

    2009-04-01

    Early Eocene continental breakup in the NE Atlantic Volcanic Province (NAIP) was associated with voluminous extrusive and intrusive magmatism, and initial seafloor spreading produced anomalously thick oceanic crust. Recent publications based on crustal-scale wide-angle seismic data show that there is a positive correlation between igneous crustal thickness (H) and average P-wave velocity (Vp) on all investigated margins in the NAIP. Vp can be used as a proxy for crustal composition, which can be related to the mode of mantle melting. A positive H-Vp correlation indicates that excessive mantle melting the first few million years after breakup was driven by an initial increased temperature that cools off as seafloor spreading develops, consistent with a mantle plume model. Variations in mantle composition can explain excess magmatism, but will generate a negative H-Vp correlation. Active mantle convection may increase the flux of mantle rocks through the melting zone above the rate of passive corner flow, which can also produce excessive magmatism. This would produce little H-Vp correlation, and place the curve lower than the passive flow melting curve in the diagram. We have compiled earlier published results with our own analyses of published and unpublished data from different groups to look for systematic variations in the mantle melting mode along the NAIP margins. Earlier studies (Holbrook et al., 2002, White et al, 2008) on the southeast Greenland conjugate system, indicate that the thick igneous crust of the southern NAIP (SE Greenland ? Hatton Bank) was dominated by increased mantle temperature only, while magmatism closer to the southern side of and including the Greenland-Iceland-Færøy Ridge (GIFR) was created by combined temperature increase and active mantle convection. Recent publications (Breivik et al., 2008, White et al, 2008) north of the GIFR for the Norway Basin segment, indicate temperature dominated magmatism between the Jan Mayen Fracture

    2004-12-01

    The North Atlantic igneous province (NAIP) has long been viewed as a region of anomalous mantle upwelling related to plume activity, continental rifting, and a heterogeneous mantle source. Prior to continental rifting in the Tertiary, the northern portion of the region was the site of closure of the Iapetus ocean basin. This tectonic event may have contributed to heterogeneities within the upper mantle and altered its oxidation state relative to the ambient mantle. Vanadium has been shown to be a useful indicator of redox conditions due to its multiple valence states (e.g. [1-2]). In mantle minerals, vanadium becomes increasingly incompatible under more oxidizing conditions [3]. Because both scandium and vanadium are moderately incompatible during melting, the Sc/V ratio of primitive basalts can be used to investigate the oxidation state of the mantle [1-3]. We have examined the Sc/V ratios of primitive lavas from the mid-Atlantic ridge (MAR), Iceland, and the East Greenland margin to determine if there are spatial or temporal variations in the oxidation state of the NAIP mantle. The Sc/V ratios for MAR basalts are 0.13-0.20 (GEOROC chemical database); while Icelandic basalts range from 0.10-0.25 with an average of 0.16 (1 σ =0.05). The entire range of Sc/V ratios of the Paleogene East Greenland basalts is 0.07-0.17 with an average of 0.10 (1 σ = 0.05). The Sc/V ratios of Icelandic basalts are similar to MAR basalts, but the East Greenland lavas are distinctly lower than both the MAR and Iceland. The Sc/V ratio also can vary as a function of mean pressure of melting (i.e. spinel versus garnet lherzolite). To test the relative importance of melting systematics, source composition, and oxygen fugacity on the Sc/V systematics for NAIP basalts, we incorporated the oxygen-fugacity-dependent V mineral-melt partitioning data of [3] into the polybaric decompression melting model REEBOX [4]. The best-fit model parameters for the majority of the Iceland and MAR basalts

    In this paper, both direct material input (DMI) and domestic processed output (DPO) of Jilin Province in 1990-2006 were calculated and then based on these two indexes, a dematerialization model was established. The main results are summarized as follows: (1) both direct material input and domestic processed output increase at a steady rate during 1990-2006, with average annual growth rates of 4.19% and 2.77%, respectively. (2) The average contribution rate of material input to economic growth is 44%, indicating that the economic growth is visibly extensive. (3) During the studied period, accumulative quantity of material input dematerialization is 11,543 x 10(4) t and quantity of waste dematerialization is 5,987 x10(4) t. Moreover, dematerialization gaps are positive, suggesting that the potential of dematerialization has been well fulfilled. (4) In most years of the analyzed period, especially 2003-2006, the economic system of Jilin Province represents an unsustainable state. The accelerated economic growth relies mostly on excessive resources consumption after the Revitalization Strategy of Northeast China was launched.

    For water-scarce communities in the western U.S., it is critical to understand groundwater recharge regimes and how those regimes might shift in the face of climate change and impact groundwater resources. Watersheds in the Basin and Range Geological Province are characterized by a variable precipitation regime of wet winters and variable summer precipitation. The relative contributions to groundwater recharge by summer and winter precipitation vary throughout the province, with winter precipitation recharge dominant in the northern parts of the region, and recharge from summer monsoonal precipitation playing a more significant role in the south, where the North American Monsoon (NAM) extends its influence. Stable water isotope data of groundwater and seasonal precipitation from sites in Sonora, Mexico and the U.S. states of California, Nevada, Utah, Arizona, Colorado, New Mexico, and Texas were examined to estimate and compare groundwater recharge seasonality throughout the region. Contributions of winter precipitation to annual recharge vary from 69% ± 41% in the southernmost Río San Miguel Basin in Sonora, Mexico, to 100% ± 36% in the westernmost Mojave Desert of California. The Normalized Seasonal Wetness Index (NSWI), a simple water budget method for estimating recharge seasonality from climatic data, was shown to approximate recharge seasonality well in several winter precipitation-dominated systems, but less well in basins with significant summer precipitation.

    An understanding of reserve growth in known oil and gas fields has become a critical component of energy resource analysis. Significant statistical studies of reserve growth have been published in the U.S., whereas little information is available on other regions of the world. It may be expected that in many countries the magnitude of reserve growth is different from that in the U.S. because of differences in reporting systems and in exploration and production practices. This paper describes the results of a reserve growth study in a group of largest oil and gas fields of the Volga-Ural petroleum province, Russia. The dynamics of reserve growth in these fields shows rapid reserve additions during the first 5 years of field exploration and development, which results from intensive step-out and delineation drilling. Later reserve growth is slow and is related to improvements in recovery technologies and discoveries of new pools and extensions. These two stages of reserve growth are described by two different groups of empirical models. A comparison of these models with the models developed for the lower 48 states and Gulf Coast offshore of the U.S. demonstrates that the reserve growth in the Volga-Ural province is significantly lower than in the U.S. The proposed models may be used for assessment of future reserve additions in known fields of countries that presently have or recently had a centrally-planned economic system.

    Taking 2000-2003’s data of foreign exchange income and the number of inbound tourism from as the sample, we studied the inbound tourism flow and the change of the Liquiity and the synergy degree in these cities. The flow of inbound tourism and the Liquiity in Henan province presented the characteristics of opposite change. In flow, it presents the steady uptrend, there were 3 general forms: gradually reducing, gradually rising and cross rolling type. In Liquiity, its types of high-quality and low-quality flows are basic equivalence, presents the staggered change state. Inbound tourism flow and the evolution of the Liquiity in Henan province can be divided into 3 stages, 2003 and 2008 is a node of its division. The evolution of the inbound tourism flow and Liquiity collaborative structure show that the complex conditions, especially the evolution of the synchronous 2-high type cities and synchronous middle type cities show a trend of decline. The number of later one appears to a change trend of increasing first and then, steady. The number of deviation cities is volatility. The reverse deviation cities are the most, which present a trend of decreasing at first, then coming steady.

    The first regional inventory of karst activity in the Valley and Ridge Province of East Tennessee was performed as a part of ongoing studies at Oak Ridge National Laboratory pertaining to environmental impact assessment of waste disposal in karst settings. More than half the land area in the Valley and Ridge Province of East Tennessee is underlain by karst-prone carbonate bedrock. The regional karst inventory was initiated to obtain current information on the extent of active karst subsidence in the region for use in decision making by the Department of Energy in planning future waste disposal facilities at Oak Ridge, Tennessee. The inventory was performed by contacting personnel of federal, state, and county agencies to obtain reports of known active karst subsidence within the region. Data from these interviews were tabulated resulting in identificaton of more than 250 karst subsidence incidents in East Tennessee, most of which have occurred since 1980. Although the infomation obtained was largely anecdotal, approximate location, date, size, and circumstances under which the collapses occurred were recorded for as many cases as could be documented. The study also included detailed reconnaissance of selected areas similar in geology and hydrology to a study area at Oak Ridge, Tennessee to identify causative factors which contribute to karst subsidence in the region and for comparison of the occurrence of visible karst features at different sites. Human activities affecting site hydrology such as large scale land clearing and earthmoving projects were related to most of the subsidence incidents inventoried.

    The U.S. Geological Survey (USGS) completed a geology-based assessment of undiscovered, technically recoverable conventional and continuous oil and gas resources in the part of the Ventura Basin Province that lies onshore or within State waters (within 3 miles of the shoreline) of California (fig. 1). Conventional oil and gas resources are those that have migrated upward into structural or stratigraphic traps from deep zones where the oil and gas is generated; water is present below the oil or gas. Continuous accumulations, in contrast, are those in which oil or gas is pervasively present in essentially all wells that penetrate them, that may not be structurally or stratigraphically trapped, and that typically lack oil-water or gas-water contacts. They are commonly produced with well-stimulation technology, such as hydraulic fracturing, referred to as “unconventional.” The same stimulation technology, however, is also used in many conventionally trapped accumulations. We estimated both the likely range of oil and gas volumes remaining to be discovered in accumulations similar to existing conventional oil and gas fields in the Ventura Basin Province (previously assessed by Keller [1995] as 1,060 million barrels of oil [MMBO], 1,900 billion cubic feet of gas [BCFG], and 60 million barrels of natural gas liquids [MMBNGL]), and the potential for oil and gas that might be present in a continuous accumulation at extreme depth in the floor of the basin.

    The maternal and child health and family planning (MCH/FP) level in Nghe An Province, Vietnam, has been substantially improved by campaigns for better health. For example, the contraceptive prevalence rate has sharply increased from 44% in 1993 to 76% in 1999. Such an achievement is attributed to the leaders' strong commitment to MCH/FP. They consistently directed the Health Department to develop challenging programs and campaigns. In addition, their commitment is translated into the allocation of the big amount for the health program, including MCH/FP. However, Tran Thi Thien, vice-director of the Health Department of Nghe An Province, states that such a level of MCH/FP is not satisfactory. One of the major reasons is the existence of a big gap in health services among the 19 districts. The mountainous districts are poorer compared to the plains districts. To fill this gap, strategies for MCH/FP development have been adopted. These include 1) training of health staff; 2) providing support to related agencies; 3) renovating health facilities; 4) providing medical equipment and instruments; and 5) development of special information, education and communication services for mountainous districts. Development of this alternative program has been greatly assisted by international donors such as the UN Population Fund, the Japan International Cooperation Agency and the World Bank.

  13. The Niger Delta petroleum system; Niger Delta Province, Nigeria, Cameroon, and equatorial Guinea, Africa

    In the Niger Delta province, we have identified one petroleum system--the Tertiary Niger Delta (Akata-Agbada) petroleum system. The delta formed at the site of a rift triple junction related to the opening of the southern Atlantic starting in the Late Jurassic and continuing into the Cretaceous. The delta proper began developing in the Eocene, accumulating sediments that now are over 10 kilometers thick. The primary source rock is the upper Akata Formation, the marine-shale facies of the delta, with possibly contribution from interbedded marine shale of the lowermost Agbada Formation. Oil is produced from sandstone facies within the Agbada Formation, however, turbidite sand in the upper Akata Formation is a potential target in deep water offshore and possibly beneath currently producing intervals onshore. Known oil and gas resources of the Niger Delta rank the province as the twelfth largest in the world. To date, 34.5 billion barrels of recoverable oil and 93.8 trillion cubic feet of recoverable gas have been discovered. In 1997, Nigeria was the fifth largest crude oil supplier to the United States, supplying 689,000 barrels/day of crude.

    Objectives This study attempted to identify the factors that contribute to successful telemedicine service. This was done by analyzing the operational state of successful telemedicine services offered in Gangwon Province of Korea and their outcome for the last fifteen years. Methods A comparative analysis was made based on reports and a thesis on the satisfaction rate of patients and providers, patient compliance to treatment, and economic assessment of Gangwon telemedicine service, which were carried out in three periods: the years 2006, 2010, and 2012. Results The satisfaction surveys in all three periods showed similar results for patients (4.46±0.70 point) and healthcare practitioners, including nurses (3.82±0.62 point) and physicians (3.60±0.56 point), in decreasing order from the year 2012. Through the survey of patients' compliance with treatment, it was confirmed that telemedicine services increased patients' compliance with drug administration, facilitated improvement of lifestyle habits, improved glycated hemoglobin for patients with diabetes mellitus, and enhanced the rate of blood pressure control. In the survey conducted on patients' willingness to pay for telemedicine services in 2007, it was found that those patients were willing to pay about $3.5 for services. Conclusions The telemedicine services of Gangwon Province increased patients' compliance with drug administration, improved blood glucose control, enhanced blood pressure control for patients with hypertension, and provided economic advantage.

  15. Heat flow in the Basin and Range province and thermal effects of tectonic extension

    USGS Publications Warehouse

    Lachenbruch, A.H.

    1978-01-01

    In regions of tectonic extension, vertical convective transport of heat in the lithosphere is inevitable. The resulting departure of lithosphere temperature and thickness from conduction-model estimates depends upon the mechanical mode of extension and upon how rapidly extension is (and has been) taking place. Present knowledge of these processes is insufficient to provide adequate constraints on thermal models. The high and variable regional heat flow and the intense local heat discharge at volcanic centers in the Basin and Range province of the United States could be accounted for by regional and local variations in extensional strain rate without invoking anomalous conductive heat flow from the asthenosphere. Anomalous surface heat flow typical of the province could be generated by distributed extension at average rates of about 1/2 to 1%/m.y., similar to rates estimated from structural evidence. To account for higher heat flow in subregions like the Battle mountain High, these rates would be increased by a factor of about 3, and locally at active bimodal volcanic centers, by an order of magnitude more. ?? 1978 Birkha??user Verlag.

    An epidemiological study of brucellosis was carried out in 516 goats and mixed flocks (goat/sheep) from the three agro-ecological regions of Formosa province, Argentina. Serum samples from a total of 25401 goats and 2453 sheeps were analyzed using buffered plate agglutination test (BPAT) and complement fixation test (CFT). Bacteriological and PCR analyses on milk samples from goats in three flocks with a history of brucellosis and recent abortions were also performed. Brucellosis was detected in four of the nine departments of the province with an overall prevalence of 2% and an intra-flock prevalence ranging between 1% and 40%. The proportion of infected flocks was 3.6%, 12% and 36% for the eastern, central and western regions, respectively. Brucella melitensis bv. 1 was isolated efrom goats for the first time in the province. The expected fragments of 827bp from the omp2ab gene (Brucella spp.) and 731bp from the insert IS711 (B. melitensis) were amplified by PCR. Detection of antibodies by BPAT and FCT in sheep cohabiting with goats suggests that infections could have been caused by B. melitensis, posing an additional risk to public health. Control and eradication programs for brucellosis should consider mixed flocks as a single epidemiological unit. The results indicate that brucellosis by B. melitensis bv1 is highly endemic in the central and western regions of Formosa province.

  3. Critically Pressured Free Gas Reservoirs Below Gas Hydrate Provinces

    Paleoceanographic evidence suggests that methane hydrates play a significant role in global climate change; however, mechanisms for sustained methane release into the biosphere during periods of global warming are poorly understood (Katz et al. 1999, Kennett et al., 2000). Here, we evaluate the possibility that gas flux into the hydrate stability zone, and perhaps into the oceans and atmosphere is mechanically regulated by hydrofracture or fault reactivation in overlying hydrate-bearing sediments. Our results reveal that a critical gas column thickness exists below most hydrate provinces in basin settings, implying that these hydrate provinces are poised for mechanical failure. Our results suggest that a free gas "wedge" of increasing thickness with BSR depth occurs in hydrate basins, and that a mechanically regulated maximum thickness of free gas exists. Furthermore, our results are consistent with observations of thicker free gas zones in deep hydrate basins and thin free gas zones on active, possibly water-phase overpressured, continental margins. Incorporating our result with Dickens' 2001 model for estimating BSR depths along ocean margins, and assuming 50% sediment porosity with gas filling 1% of the pore space, we calculate a value for the total free methane gas reservoir below all hydrate provinces to be 1/8 the total methane trapped in hydrate, or ~1300 Gt if 10,000 Gt of methane exists in hydrate (Kvenvolden, 1993). One key implication is that a significant reservoir of methane may exist as free gas beneath hydrate provinces that is highly sensitive to changes in pressure and temperature.

    In 1955, the area infested by Aedes aegypti in Argentina was estimated as 1,500,000 km2; and in 1963, the species was considered to be eradicated from Argentina. In 1995, the Argentine Ministry of Health reported reinfestation by Ae. aegypti. During 1994-95, the Ministry of Health of Córdoba Province, Zoonosis Department, established a surveillance system for Ae. aegypti in Córdoba Province, Argentina. This report is a summary of results obtained thus far. In total, 74 localities in Córdoba Province were sampled during August 1994-April 1996, resulting in 5 positives (6.7%): Villa María city, Villa Nueva, and Córdoba city in 1995, and Juarez Celman and Jesús María in 1996. In Villa María and Villa Nueva, Ae. aegypti was present until June 1995 (autumn) and reappeared in December 1995. In Córdoba city, Ae. aegypti was eliminated from the only positive house in May 1995, but it reappeared in March 1996. Reappearance of Ae. aegypti in this temperate area in early summer may have been due to the survival of individuals during winter and not to reintroduction during summertime. The last previous active surveillance for Ae. aegypti in Córdoba Province was carried out more than 30 years ago.

  6. The deforestation of rural areas in the Lower Congo Province.

    The Lower Congo is one of eleven provinces in the Democratic Republic of Congo, and is located southwest of Kinshasa Town Province. It has an area of approximately 53.947 km2 with a population of 1,504,361 at an estimated 237 persons per km2. The Province comprises five districts, including Lukaya and Cataracts where rural poverty is severe and the population struggle to make a living through agriculture and woodcutting. These activities result in excessive resource exploitation. The high demand for foodstuffs and the high consumption of wood (for energy, construction and export) in Kinshasa, the capital city of the Democratic Republic of Congo and the expanding towns of Matadi and Boma in the Lower Congo Province, are speeding the deforestation rate and unbalancing forest ecosystems. In addition there is the stress resulting from reduced josher (the rest period for agriculture ground), plus climate change and erosion. The phenomena that that we need to address in these two districts include deforestation, reduced josher, excessive agriculture, erosion, burning and climate change which taken together largely explain the current soil degradation. These areas are marked by excessive post deforestation savannah formation and extended areas of sandy soil, distributed throughout grass and shrub savannahs. This desertification, which is rampant in Lukaya and Cataracts, risks imprisoning the rural population in a vicious cycle of poverty if adequate solutions are not found.

    Cancer is the second leading cause of death in developing countries. In Iran, cancer is the third cause of death. The present study aimed at providing the incidence rates (crude and agestandardized) of different types of cancers in Sistan and Baluchestan province (Southeastern of Iran). Data were collected retrospectively reviewing all new cancer patients registered in Cancer Registry Center of Health Heputy for Sistan and Baluchestan province. Common cancers were defined based on the number of cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. A total of 3535 cases of cancers registered during 2004-2009 were identified. Of these, 46.82% occurred in females and 53.18% in males. The most frequent cancer in women was breast cancer followed by esophagus, skin, colorectal and leukemia. The 5 most frequent cancers in men were stomach, skin, leukemia, esophagus and bladder. Joinpoint analyze showed a significant increasing trend for adjusted standard incidence rate (ASIR) for both sexes (p<0.05). According to The results of the present study and comparison to previous studies for other provinces in Iran, cancer incidence in Sistan and Baluchistan is less common but trends of cancers are increasing in Sistan and Baluchestan Province. It is necessary to have a comprehensive health policy for prevention and control of this problem.

    This study established a set of indicators for and evaluated the effects of health care system reform in Hubei Province (China) from 2009 to 2011 with the purpose of providing guidance to policy-makers regarding health care system reform. The resulting indicators are based on the "Result Chain" logic model and include the following four domains: Inputs and Processes, Outputs, Outcomes and Impact. Health care system reform was evaluated using the weighted TOPSIS and weighted Rank Sum Ratio methods. Ultimately, the study established a set of indicators including four grade-1 indicators, 16 grade-2 indicators and 76 grade-3 indicators. The effects of the reforms increased year by year from 2009 to 2011 in Hubei Province. The health status of urban and rural populations and the accessibility, equity and quality of health services in Hubei Province were improved after the reforms. This sub-national case can be considered an example of a useful approach to the evaluation of the effects of health care system reform, one that could potentially be applied in other provinces or nationally.

Nuclear acids were extracted from blood samples of 16 HIV-1 infected individuals collected locally in Liaoning province of China from Jun. 1997 to Dec. 2000. The 0.7 kb or 1.2 kb segments of HIV-1 env gene were amplified using nested-PCR and the HIV-1 genetic subtypes were then assayed by heteroduplex mobility assay. Fifteen of 16 samples were positive by PCR amplification of HIV-1 env region and samples were found to be genetic subtype A,B',C,E. The proportion due to sexual transmission in all HIV infection was 31.25% (5/15), among which subtype B' (3/5) was the majority. A man who returned from Africa together with his spouse both had type A (2/5) infection. Intravenous drug users (IDUs) took up 31.25% (5/15) of all the HIV infections. Subtype C (2/4) and E were predominant among intravenous drug users. However, there was one IDU with subtype B or E. Nearly all blood recipients and blood donors were B' (4/5) except one with C. There have been several subtypes of HIV-1 existed in Liaoning province, demonstrating the complexity of HIV epidemology in Liaoning province and the difficulty conducting prevention and treatment.

    By using IPCC carbon emission calculation formula (2006 edition), economy-carbon emission dynamic model, and cement carbon emission model, a regional carbon emission calculation framework was established, and, taking Guangdong Province as a case, its energy consumption carbon emission, cement production CO2 emission, and forest carbon sink values in 2008-2050 were predicted, based on the socio-economic statistical data, energy consumption data, cement production data, and forest carbon sink data of the Province. In 2008-2050, the cement production CO2 emission in the Province would be basically stable, with an annual carbon emission being 10-15 Mt C, the energy consumption carbon emission and the total carbon emission would be in inverse U-shape, with the peaks occurred in 2035 and 2036, respectively, and the carbon emission intensity would be decreased constantly while the forest carbon sink would have a fluctuated decline. It was feasible and reasonable to use the regional carbon emission calculation framework established in this paper to calculate the carbon emission in Guangdong Province.

    Background: Tuberculosis (TB) is one of the main health issues in Turkey. Extrapulmonary TB cases have significant proportion comparing pulmonary TB cases. The aim of the study was to evaluate the extrapulmonary tuberculosis (EPTB) cases in two regions of Turkey, which have different demographic and socioeconomic characteristics. Methods: In this retrospective cohort study, EPTB cases between 2000 and 2005 in Van and Izmir Provinces of Turkey were analyzed and compared for symptoms, age groups, vaccination status, diagnostic procedures and social-economical conditions within two provinces. Descriptive analytic methods were used. Results: Total of 397 EPTB cases were reviewed retrospectively in Izmir and Van provinces. Pleural TB was most often seen EPTB form (47.6% vs. 32.6%) and female/male ratio was similar in both groups. Patients were in older ages in Izmir Province. Chest pain (20% vs. 32%), cough (33% vs. 26%) and night sweatiness (29% vs. 36%) were leading complaints. Low BCG vaccination rate and higher childhood EPTB were found in Van group, in contrary elderly EPTB was more often in of Izmir group. Conclusion: Frequency of severe forms of EPTB is more often in younger ages in lower social economical condition areas. PMID:27141492

    Isocyanates such as toluene 2, 4-diisocyanate (TDI), methylene bisphenyl isocyanate (MDI), and hexamethylene diisocyanate (HDI) are known sensitizers and exposure to these chemicals can result in isocyanate-induced asthma-the leading cause of occupational asthma. A newly created exposure database was available containing occupational isocyanate measurements spanning 1981-1996 from Ontario and British Columbia (BC)-two of the largest provinces in Canada. The aim was to describe the historical measurements relative to exposure thresholds, ascertain differences in the data between provinces, and identify time trends. Descriptive statistics of the observations were summarized and stratified by isocyanate species and province. Chi-square tests and Student's t-test were performed to determine differences between provinces. To investigate time trends in the odds of a measurement exceeding the limit of detection (LOD) and time-weighted average (TWA), mixed effects logistic regression models were constructed. In total, 6,984 isocyanate measurements were analyzed, the majority of which were below the LOD (79%). Overall, 8.3% of samples were in excess of the 2014 TLV-TWA of 0.005 ppm. Comparing the two provinces, the proportion of samples exceeding the LOD and TLV-TWA was greater in BC for all isocyanate species. Differences in time trends were also observed between provinces-the odds of a sample exceeding the TLV-TWA decreased over time in the case of MDI (Ontario only), TDI (both Ontario and BC), and other isocyanates (BC only). Our finding that a majority of the exposure measurements was below the LOD is similar to that reported by others. Differences between provinces may be due the fact that isocyanates are classified as a designated substance in Ontario and must adhere to specific exposure control regulations. Limitations of the database, such as finite number of variables and measurements available until 1996 only, presents challenges for more in-depth analysis and

    2007-01-01

    INTRODUCTION The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas resources of the Denver Basin Province (USGS Province 39), Colorado, Kansas, Nebraska, South Dakota, and Wyoming. Petroleum is produced in the province from sandstone, shale, and limestone reservoirs that range from Pennsylvanian to Upper Cretaceous in age. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define seven total petroleum systems and twelve assessment units. Nine of these assessment units were quantitatively assessed for undiscovered oil and gas resources. Gas was not assessed for two coal bed methane assessment units due to lack of information and limited potential; oil resources were not assessed for the Fractured Pierre Shale Assessment Unit due to its mature development status.

It extends over approximately 740,000 km² and has a N-S elongated central depression containing the calderas of Meroe Patera and Nili Patera. Lava thicknesses range from approximately 0.5-1.0 km and total volume of erupted material has been estimated at about 320,000 km³. This province is another target area of our ongoing study to quantify the global volatile release during volcanic eruptions on Mars. Estimates of eruption frequency, associated volume of erupted material, and gas release to the atmosphere are the key parameters of this research. Reconstruction of the eruption history of volcanic provinces is one of the steps to be taken in order to constrain these parameters. In total, 58 lava flows were mapped of which 39 were suitable for age determination using crater size-frequency distributions. In addition, the caldera of Meroe Patera was also dated using crater statistics. Model ages range between 0.87 Ga and 3.63 Ga. There is no apparent time-space correlation observed. The broad spectrum of model ages, ranging from Early Hesperian to Middle Amazonian, points to long-lasting volcanic activity of the studied province. This fact together with post-emplacement deformation of lava flows indicates a much longer eruption and volcano-tectonic history of the Syrtis Major Volcanic Province than previously thought, extending it to the Middle Amazonian period

    Brindisi is a town on the South coast of the Adriatic sea, where many sources of airpollutants are located nearby the urban area. A part from the airport and the harbour, mainly for passenger traffic to Greece, a wide industrial area is present (petrochemical, power plants, chemical pharmaceutical, metallurgical, manufacturing). In seven municipalities, illegal dumps have been found. South west of Brindisi is the province of Taranto, whose industrial area includes steels factory a refinery and a cement factory. In both provinces, an area at "high risk of environmental crisis, has been identified by the Italian Ministry of Environment. In the Brindisi area, mortality from all causes, cancers and respiratory diseases. in 1990-1994 was found to be in excess. to estimate mortality among residents in the twenty municipalities of the province aggregated in four geographic areas: the one at "high risk" including the main town, and the areas located North. West and South of the Brindisi "high risk" area. descriptive geographical study. mortality analysis by gender, specific causes of death and two ten-year periods between 1981 and 2001. Standardised mortality ratios (Puglia region as referent population) and directly as well as age-standardized rates (ref. European population) have been computed. mortality from all causes and from forty selected causes. about 3,200 annual deaths have occurred in the province. Results for the high risk area confirm previous analyses while excesses in the other areas have appeared. A few municipalities, requiring a deeper investigation have been identified. Such excesses refer to mortality due to all causes, all cancers, stomach and lung cancers, respiratory and ischemic diseases. this study confirms excesses in the high risk areas and found mortality excesses in other municipality both among males and females. The results suggest to further investigate mortality both in the main town and in the small municipalities where illegal dump have

    Matabeleland South launched the malaria pre-elimination campaign in 2012 but provincial spraying coverage has failed to attain 95% target, with some districts still encountering malaria outbreaks. A study was conducted to evaluate program performance against achieving malaria pre-elimination. A descriptive cross sectional study was done in 5 districts carrying out IRS using the logical framework involving inputs, process, outputs and outcome evaluation. Health workers recruited into the study included direct program implementers, district and provincial program managers. An interviewer administered questionnaire, checklists, key informant interviewer guide and desk review of records were used to collect data. We enrolled 37 primary respondents and 5 key informants. Pre-elimination, Epidemic Preparedness and Response plans were absent in all districts. Shortages of inputs were reported by 97% of respondents, with districts receiving 80% of requested budget. Insecticides were procured centrally at national level. Spraying started late and districts failed to spray all targeted households by end of December. The province is using makeshift camps with inappropriate evaporation ponds where liquid DDT waste is not safely accounted for. The provincial IHRS coverage for 2011 was 84%. Challenges cited included; food shortages for spraymen, late delivery of inputs and poor state of IHRS equipment. The province has failed to achieve Malaria pre-elimination IRS coverage targets for 2011/12 season. Financial and logistical challenges led to delays in supply of program inputs, recruitment and training of sprayers. The Province should establish camping infrastructure with standard evaporation ponds to minimise contamination of the environment.

    Ticks carry and transmit a remarkable array of pathogens including bacteria, protozoa and viruses, which may be of veterinary and/or of medical significance. With little to no information regarding the presence of tick-borne zoonotic pathogens or their known vectors in southern Africa, the aim of our study was to screen for Anaplasma phagocytophilum, Borrelia burgdorferi, Coxiella burnetii, Rickettsia species and Ehrlichia ruminantium in ticks collected and identified from ruminants in the Eastern Cape, Free State, KwaZulu-Natal and Mpumalanga Provinces of South Africa. The most abundant tick species identified in this study were Rhipicephalus evertsi evertsi (40%), Rhipicephalus species (35%), Amblyomma hebraeum (10%) and Rhipicephalus decoloratus (14%). A total of 1634 ticks were collected. DNA was extracted, and samples were subjected to PCR amplification and sequencing. The overall infection rates of ticks with the target pathogens in the four Provinces were as follows: A. phagocytophilum, 7%; C. burnetii, 7%; E. ruminantium, 28%; and Rickettsia spp., 27%. The presence of B. burgdorferi could not be confirmed. The findings of this study show that zoonotic pathogens are present in ticks in the studied South African provinces. This information will aid in the epidemiology of tick-borne zoonotic diseases in the country as well as in raising awareness about such diseases in the veterinary, medical and tourism sectors, as they may be the most affected.

    Dikes in the southeastern United States represent a major component of the Central Atlantic magmatic province and record kinematics of Pangean breakup near the critical, predrift junction of three major continental masses. Until now, the age of these dikes had not been determined with the same precision as those of Central Atlantic magmatic province basalts on other parts of the circum-Atlantic margin. Our new results for three dike samples from the South Carolina Piedmont yield plateau ages of 198.8 ± 2.2, 199.5 ± 1.8, and 199.7 ± 1.5 Ma. For comparison, we present new age determinations of the benchmark Watchung flows I and III of the Newark basin: 201.0 ± 2.1 and 198.8 ± 2.0 Ma, respectively. Collectively, these data suggest that basaltic volcanism responsible for the dikes, flows, and sills of eastern North America occurred within ˜1 m.y. of 200 Ma. The timing, brief duration, and extent of the Central Atlantic magmatism imply that it may have been causally related to Triassic-Jurassic mass extinctions. The distribution and timing of this magmatism and the absence of regional uplift or an identifiable hotspot track lead us to favor strong lithospheric control on the origin of the Central Atlantic magmatic province, consistent with the modern generation of plume incubation or edge-driven convection models.

    Introduction Neurocysticercosis being a potential to human transmitted disease, is the major cause of seizures and a public health problem in tropical countries. Though India is known to be highly endemic, there are many provinces where reports are still unavailable thereby underestimating its actual burden. Materials and Methods Anti-Cysticercus IgG antibodies in sera from cases presenting with seizures were screened by ELISA in a preliminary study in Odisha state which is a province in Eastern coastal India that was never explored before. Patients presenting with recent onset of seizures within age group 5 to 50 years, either local residents of Odisha or inhabitants from other parts of the country living for at least one year period in the study area were included. Results The present study showed 28.12% cases with seizures to be confirmed neurocysticercosis (NCC) based on serology and brain imaging. However, statistically no association was established between anti-Cysticercus antibody detection and radio imaging characteristics (location, number of lesions, and stage). Conclusion This is the first study in Odisha presenting a series of cases with serological evidence of exposure to the parasite along with imaging characteristics which was consistent with NCC. It is recommended that NCC must be considered for a differential diagnosis in each active epilepsy case irrespective of prior prevalence information in all unexplored provinces in India and other endemic regions; also a compulsory reporting is warranted in order to aid in quantifying its actual burden.

    Background. Geographical variation in the incidence of Crohn's disease (CD) has been reported in Europe and North American. However, there are no comparable data in mainland China. Methods. We retrospectively identified incident cases of CD patients registered in Jinling hospital during 2003 to 2012. The standardized incidence ratio (SIR) was calculated for each area of Jiangsu province and a thematic map of CD was made according to the local SIR. The association between incidence and local economic status was revealed by correlation between SIR of CD and different local economic indicators. Results. A total of 653 CD patients (male-to-female ratio, 1.8 : 1) from Jiangsu province were included. A steady increase was observed in the number of CD patients over the period of observation. Disease map of SIR showed a pronounced geographic concentration of CD in the south part of Jiangsu province. Spearman correlation analysis showed a positive correlation between local SIR of CD and local economic indicators. Conclusions. There is a marked geographic variability in CD incidence across Jiangsu province. CD incidence in affluent areas seems to be higher than that in less affluent areas. Further multicenter population-based studies are needed to assess the real disease map of CD. PMID:24839438

    Background: As geographic science discusses the analysis of environment, human beings and their mutual relations, thus the field of medical geography consists of being inspired from the relations between these two factors, analyzing environmental factors, their identification them and the state of their effects on human health, as well as determining the location of these factors. Some hazards that threat human health are the results of environmental factors and the relevant pollutions. Some important categories of diseases including (Shortness of Breath or, Dyspnea) have considerable differences in various places, as observed in their spatial prevalence and distribution maps. Methods: The record of patients with Dyspnea diseases were prepared for this descriptive research, for the period of 2009-2011, from the provincial health center, with the questionnaires were excluded patients with a family history of disease and the spatial diagram for disease prevalence was drawn according to the prepared data. The arsenic geographical distribution diagram in Isfahan province was also prepared and then the relation between an element of Arsenic in the province and the Dyspnea diseases were analyzed. Results: The analyses showed that the highest rate of Arsenic is entered the soil via fertilizers to come eventually into the food cycle of humans. By analyzing the amount of used fertilizers in Isfahan province and the dispersion diagram of Arsenic in Isfahan province, it was found that the highest frequency of Arsenic is in places having agricultural base. The spatial dispersion of Dyspnea diseases also showed that the spreading of Dyspnea diseases is greater in places with higher scale of Arsenic. Conclusions: This study is a logical justification between the two diagrams to confirm the hypothesis regarding the effect of arsenic on Dyspnea. PMID:25538832

  17. Interaction Between the Supercontinent Cycle and the Evolution of Intrinsically Dense Provinces in the Deep Mantle

    Shear-wave travel times in the Earth's deep mantle reveal broad steep-sided seismologically distinct provinces lying on the Core-Mantle Boundary (CMB). The longevity and permanence of the two large principal provinces, located below the sites of present-day Africa and the Pacific Ocean, have become a matter of great interest. Examination of the flood basalt record and kimberlite eruption dating suggests the presence of these provinces may disclose a deep mantle component with a compositionally distinct origin playing a role in the generation of mantle plumes at preferred locations. By extension, the presence of these provinces may affect the supercontinent cycle. Implementing a mantle convection model featuring distinct continental lithosphere and a Compositionally Anomalous and Intrinsically Dense (CAID) component, we study the distribution and mobility of naturally forming compositionally distinct provinces and their impact on model supercontinent assembly. In calculations featuring Earth-like convective vigor and global scale we find that an intrinsically dense mantle component generally aggregates into one or two broad provinces. The positions of the provinces are time-dependent but in many of our calculations the province locations are characterized by periods of fixity that reach several hundred million years. Eras of province and associated plume fixity are punctuated by periods of relatively rapid migration. A correlation between supercontinent position and the locations of CAID provinces is not supported by our findings. However, we find the frequency of supercontinent assemblies increases when CAID provinces are present.

    The analytical hierarchy process (AHP) was adopted to study the index system of eco-province and the index system was set up for eco-province construction. The comparison matrix was constructed on the basis of experts' investigation questionnaires. MATLAB 6.5 was used to confirm the weights of the indices. The general environment quality index model was used to grade the environment quality and assessed the progress of constructing eco-province in Heilongjiang province. The results indicate that it is feasible to apply the AHP to assess quantitatively the ecological environmental quality province-wide. The ecological environment quality of Heilongjiang province has been improved obviously from the beginning of eco-province construction.

    The late Neoproterozoic (ca. 700 730 Ma) Mechum River Formation is exposed as a structural inlier within Grenvillian basement in the Blue Ridge province of central Virginia, United States. The southern portion of the Mechum River belt preserves evidence of glaciomarine sedimentation at the margin and basinward of grounding-line fans. Subaqueous glacial till, coarse-grained rhythmites, and dropstones record the incursion of ice into the basin. Marine deposition is evidenced by persistent laminations (cyclopsams) in rhythmically bedded diamictite and possibly by tidally pumped, distal turbidites in laminated mudstones. Glaciomarine sedimentation in the Mechum River Formation may have been coeval with Sturtian-Rapitan glaciations in northwestern Laurentia and Australia, and provides further evidence for a globally cold climate during the late Neoproterozoic.

    Vascular affections of the brain remain a formidable psychiatric challenge nowadays. According to WHO reports cerebrovascular disorders constitute one of the three chief causes of mortality in the population of the economically developed countries of the world. The most important cause of vascular psychoses is considered to be atherosclerosis and hypertensive disease. Today vascular psychoses have become a most common type of abnormal mental states in young adults (greater then 30-40 years old). The studies made have yielded evidence in support of the psychoses morbidity to be dependent upon particular season of year as well as on the climatic features of the locality. Natural factors have been found out to affect the prevalence of vascular psychoses in Chernivtsi Province. The findings obtained suggest to us a substantial prevalence of atherosclerotic and hypertensive psychoses in the plains-men living under conditions of a mild climate.

    2010-03-31

    Flood basalts are receiving increasing attention as possible host formations for geologic sequestration of anthropogenic CO2, with studies underway in the United States, India, Iceland, and Canada. As an extension of our previous experiments with Columbia River basalt, basalts from the eastern United States, India, and South Africa were reacted with aqueous dissolved CO2 and aqueous dissolved CO2-H2S mixtures under supercritical CO2 (scCO2) conditions to study the geochemical reactions resulting from injection of CO2 in such formations. The results of these studies are consistent with cation release behavior measured in our previous experiments (in press) for basalt samples tested in single pass flow through dissolution experiments under dilute solution and mildly acidic conditions. Despite the basalt samples having similar bulk chemistry, mineralogy and apparent dissolution kinetics, long-term static experiments show significant differences in rates of mineralization as well as compositions and morphologies of precipitates that form when the basalts are reacted with CO2-saturated water. For example, basalt from the Newark Basin in the United States was by far the most reactive of any basalt tested to date. Carbonate reaction products for the Newark Basin basalt were globular in form and contained significantly more Fe than the secondary carbonates that precipitated on the other basalt samples. In comparison, the post-reacted samples associated with the Columbia River basalts from the United States contained calcite grains with classic dogtooth spar morphology and trace cation substitution (Mg and Mn). Carbonation of the other basalts produced precipitates with compositions that varied chemically throughout the entire testing period. Examination of polished cross sections of the reacted grains by scanning electron microscopy and energy dispersive x-ray spectroscopy show precipitate overgrowths with varying chemical compositions. Compositional differences in the

    More than 40 percent of California's drinking water is from groundwater. To protect this vital resource, the State of California created the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The Priority Basin Project of the GAMA Program provides a comprehensive assessment of the State's groundwater quality and increases public access to groundwater-quality information. The San Diego Drainages Hydrogeologic Province (hereinafter referred to as San Diego) is one of the study units being evaluated. The San Diego study unit is approximately 3,900 square miles and consists of the Temecula Valley, Warner Valley, and 12 other alluvial basins (California Department of Water Resources, 2003). The study unit also consists of all areas outside defined groundwater basins that are within 3 kilometers of a public-supply well. The study unit was separated, based primarily on hydrogeologic settings, into four study areas: Temecula Valley, Warner Valley, Alluvial Basins, and Hard Rock (Wright and others, 2005). The sampling density for the Hard Rock study area, which consists of areas outside of groundwater basins, was much lower than for the other study areas. Consequently, aquifer proportions for the Hard Rock study area are not used to calculate the aquifer proportions shown by the pie charts. An assessment of groundwater quality for the Hard Rock study area can be found in Wright and Belitz, 2011. The temperatures in the coastal part of the study unit are mild with dry summers, moist winters, and an average annual rainfall of about 10 inches. The temperatures in the mountainous eastern part of the study unit are cooler than in the coastal part, with an annual precipitation of about 45 inches that occurs mostly in the winter. The primary aquifers consist of Quaternary-age alluvium and weathered bedrock in the Temecula Valley, Warner Valley, and Alluvial Basins study areas, whereas in the Hard Rock study area the primary aquifers consist mainly of fractured and

    The Upper White River, which drains about 40 percent of the Ozarks Ecoregion, is the main drain for the Ozark Plateaus and is characteristic of rivers draining other karst areas within the United States and the world. The proposed Ozark Plateaus Hydrologic Observatory (OPHO) encompasses twelve 8-digit hydrologic units covering about 67,000 km2 in parts of three states (Arkansas, Missouri, and Oklahoma). Six major U.S. Army Corps of Engineers reservoirs are within the OPHO including four on the main stem of the White River and one on the Illinois River. Karst features are prominent in the Salem, Ozark, and Springfield Plateaus of the OPHO, and include numerous solutionally enlarged fractures, caves, sinkholes, and sinking streams. Within the basin are numerous and diverse biological communities, representing influences from 1) eastern deciduous forest, 2) Great Plains prairies, 3) arid southwest, and 4) relicts of northern species from the Pleistocene Ice Age. Also contain in the OPHO is a diverse and unique array of mussels, an imperiled river organism (38 species), and crayfish. In the extensive karst regions of the OPHO are found largely endemic subterranean organisms also dependent on good water quality: for example, the Ozark Cavefish, Bristly Cave Crayfish and the recently federally- listed Tumbling Creek Cave Snail. Mantled karst aquifers characteristic of the Ozark Plateaus Region represent a coupled atmospheric/surface water/groundwater system that is highly susceptible to external forcing. Little attenuation of contaminants occurs as water moves from surface sources into and through the mantled karst aquifer to discharge naturally at springs and streams throughout the Ozark Plateau Region, and to wells. Because of the very open character of the aquifer, extremely dynamic biogeochemical cycling of nutrients occurs. Upper White River Reservoir development, filling and operation historically have altered and continue to alter the hydrologic and ecosystems

    The effect on immunisation coverage of applying guiding principles to the management of primary health care services in a province in Papua New Guinea is described. These principles were: (a) Each health centre should have a defined geographical area of responsibility. (b) Each health centre should be responsible for a defined population. (c) Each health centre should have defined target groups for immunisation and child health clinic enrolment. (d) An accurate and meaningful reporting system is essential. (e) Each health centre should receive regular feedback on its achievements. Immunisation coverage in the province, as judged by the proportion of children under 1 year of age receiving their second dose of triple antigen, improved from 57-67% in 1980-2 to 89-94% in 1983-4. Immunisation is the most cost effective preventive activity undertaken in child health care. The application of these guiding principles would be relevant in the United Kingdom. PMID:3135060

    The report summarizes the Louisianian Demonstration Project conducted by the Estuaries Resource Group of the Environmental Monitoring and Assessment Program (EMAP), a national program initiated by EPA to integrate efforts of governmental agencies in evaluations of status and trends of ecological resources of the U.S. The Louisianian Province represents a single biogeographic area corresponding to the Gulf of Mexico. The demonstration project was conducted during July and August 1991, using a probability-based sampling design to evaluate the condition of Gulf of Mexico estuarine resources. The assessment is preliminary and its findings should be confirmed by subsequent years of sampling in the Louisianian Province, which extends from Rio Grande, Texas, to Anclote Anchorage, Florida.

    In this report an attempt has been made to summarize and in places to interpret the published information that was available through 1938 on the geology of those parts of Nevada, California, and Utah that are included in the geologic province known as the Basin and Range province. This region includes most of the Great Basin, from which no water flows to the sea, as well as part of the drainage basin of the lower Colorado River. It is characterized by numerous parallel, linear mountain ranges that are separated from one another by wide valleys or topographic basins. All the major divisions of geologic time are represented by the rocks exposed in this region. The oldest are of pre-Cambrian age and crop out chiefly along the eastern and southern borders. They have been carefully studied at only a few localities, and the correlation and extent of the subdivision so far recognized is uncertain. There appear to be at least three series of pre-Cambrian rocks which are probably separated from one another by profound unconformities. Large masses of intrusive igneous rocks have been recognized only in the oldest series. During the Paleozoic era the region was a part of the Cordilleran geosyncline, and sediments were deposited during all of the major and most of the minor subdivisions of the era. There are thick and widespread accumulations of Cambrian and Ordovician strata, the maximum aggregate thickness possibly exceeding 23,000 feet. The eastern and western boundaries of the province were approximately those of the area of rapid subsidence within the geosyncline, though the axes of maximum subsidence oscillated back and forth during the two periods. The Silurian and Devonian seas, on the other hand, extended beyond the province and, possibly as a consequence, are represented by much thinner sections - of the order of 6,000 feet. At the end of the Devonian period the geosyncline was split by the emergence of a geanticline in western Nevada, and Mississippian and

    The U.S. Atlantic offshore, especially the mid-Atlantic, was an exciting exploration area from the 1970s into the 1980s. Much pioneering 'frontier' activity in both scientific and policy matters occurred in this area. Although production was not achieved, objective geological evidence indicates that the province does have potential. Major population centers of the mid-Atlantic area demand large amounts of energy and enormous amounts of crude and product are shipped through East Coast waters. Nevertheless, exploration has been shut down by moratoria, environmental concerns, and international pricing. It is suggested that the province will be revisited in the future and that the geologic and environmental information that has been generated at great cost should be preserved for use by the next generation of explorationists and policy-makers.

    Several irregularly shaped craters located within Arabia Terra, Mars, represent a new type of highland volcanic construct and together constitute a previously unrecognized Martian igneous province. Similar to terrestrial supervolcanoes, these low-relief paterae possess a range of geomorphic features related to structural collapse, effusive volcanism and explosive eruptions. Extruded lavas contributed to the formation of enigmatic highland ridged plains in Arabia Terra. Outgassed sulphur and erupted fine-grained pyroclastics from these calderas probably fed the formation of altered, layered sedimentary rocks and fretted terrain found throughout the equatorial region. The discovery of a new type of volcanic construct in the Arabia volcanic province fundamentally changes the picture of ancient volcanism and climate evolution on Mars. Other eroded topographic basins in the ancient Martian highlands that have been dismissed as degraded impact craters should be reconsidered as possible volcanic constructs formed in an early phase of widespread, disseminated magmatism on Mars.

    Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus, Liza abu, and Heteropneustes fossilis) which were found in some fish farms of the same province. The parasitic fauna included one mastigophoran, three apicomplexans, 13 ciliophorans, five myxozoans, five trematodes, 45 monogeneans, five cestodes, three nematodes, two acanthocephalans, nine arthropods, and one mollusc. The common carp was found to harbour 81 species of parasites, the grass carp 30 species, the silver carp 28 species, L. abu 13 species, C. auratus one species, and H. fossilis one species. A host-parasite list for each fish species was also provided. PMID:27559480

    For much of Kordofan Province, surface-water supplies collected and stored in hafirs, fulas, and tebeldi trees are almost completely appropriated for present needs, and water from wells must serve as the base for future economic and cultural development. This report describes the results of a reconnaissance hydrogeologic investigation of the Province and the nature and distribution of the ground-water resources with respect to their availability for development. Kordofan Province, in central Sudan, lies within the White Nile-Nile River drainage basin. The land surface is largely a plain of low relief; jebels (hills) occur sporadically, and sandy soils are common in most areas except in the south where clayey soils predominate. Seasonal rainfall, ranging from less than 100 millimeters in the north to about 800 millimeters in the south, occurs almost entirely during the summer months, but little runoff ever reaches the Nile or White Nile Rivers. The rocks beneath the surficial depsits (Pleistocene to Recent) in the Province comprise the basement complex (Precambrian), Nawa Series (upper Paleozoic), Nubian Series (Mesozoic), laterite (lower to middle Tertiary), and the Umm Ruwaba Series (Pliocene to Pleistocene). Perennial ground-water supplies in the Province are found chiefly in five hydrologic units, each having distinct geologic or hydrologic characteristics. These units occur in Nubian or Umm Ruwaba strata or both, and the sandstone and conglomerate beds form the :principal aquifers. The water is generally under slight artesian head, and the upper surface of the zone of saturation ranges from about 50 meters to 160 meters below land surface. The surficial deposits and basement rocks are generally poor sources of ground water in most of the Province. Supplies from such sources are commonly temporary and may dissipate entirely during the dry season. Locally, however, perennial supplies are obtained from the surficial deposits and from the basement rocks. Generally

    A snail survey was performed in six districts around irrigation areas of Lampao Dam, in Kalasin Province. The survey caught a total of 5,479 live snails and classed them into five families, 12 genera and 15 species, of which 7 species are suspected of transmitting human parasitic diseases. The seven species were Pila polita, Pomacea canaliculata, Filopaludina (S.) m. martensi, Bithynia (Digoniostoma) siamensis goniomphalos, Melanoides tuberculata, Radix rubiginosa, and Indoplanorbis exustus. Of these, B. (D.) s. goniomphalos and I. exustus were found to harbor emergent cercariae. Only B. (D.) s. goniomphalos hosted several types of cercariae--Opisthorchis viverrini, unidentified species of intestinal flukes, echinostomes, xyphidio and furcocercous cercariae. Indoplanorbis exustus shed only echinostome cercariae. B. (D.) s. goniomphalos showed a rather high natural infection rate with O. viverrini, 1.3% in Yang Talat district, and 0.61% in Kamalasai district, in Kalasin Province.

    Systematic airborne geophysical surveys conducted by the Alfred-Wegener-Institute over the last decades have investigated a significant part of Dronning Maud Land in East Antarctica and have revealed, amongst other findings, an aerogeophysical prominent province in southeastern Dronning Maud Land. Both its magnetic and gravity signature differs from those of the western and southwestern Dronning Maud Land, and we assume that it represents a distinct tectonic terrane. This province is characterized by a subdued magnetic anomaly field with elongated parallel positive anomalies, which are truncated by the Forster magnetic anomaly in the northwest, are flanked by the complex magnetic anomaly pattern of the Sør Rondane Mountains in the northeast, and continue presumably farther eastwards. Pronounced negative values of Bouguer gravity indicate thick continental crust of up to 50 km for this region in contrast to significantly higher values of Bouguer gravity in western and southwestern Dronning Maud Land. A few nunataks crop out within the northern portion of this province between the Wohlthat-Massiv and the Sør Rondane Mountains. In 2011 and 2012 collected rock samples from these nunataks and nearby moraines show a predominance of metasedimentary rocks of yet unknown age. Furthermore, undeformed late- to post-tectonic granitoids have been discovered within the southeastern DML province. The conclusions of these findings revise the speculation of a continuous suture zone connecting the Shackleton Range south of Coats Land in the west and the Lützow Holm Bay region in the east and supplement the hypotheses that East-Antarctica is rather a mosaic of different crustal fragments composed of Archaean nucleoids and of Proterozoic to Palaeozoic mobile belts, than to be primarily one stable craton.

  16. The Central Atlantic Magmatic Province extends into Bolivia

    The Central Atlantic Magmatic Province (CAMP) is the largest continental flood basalt (CFB) province on Earth and was associated with the onset of fragmentation of the supercontinent Pangea at the Triassic-Jurassic boundary. In order to clarify the extent of the CAMP in South America, we investigate basaltic remnants in southern Bolivia (Tarabuco, Entre Ríos and Camiri areas) by combining stratigraphic, geochronological (40Ar/39Ar data) and geochemical (major and trace element, Nd-Sr isotopes) approaches. Lava-flows reaching a total thickness up to 150 m and associated sills overlie syn-rift red beds assigned to the Triassic. The magmatic rocks consist of low-Ti tholeiites that are remarkably homogeneous in composition. Notably, their trace element and Nd-Sr isotopic compositions closely match those of CAMP basalts particularly those of southwest Brazil. 40Ar/39Ar dating failed to yield robust plateau ages but the best estimates of the crystallization age at 198.1 ± 1.5 and 199.2 ± 2.2 Ma are similar to those of CAMP basalts throughout the province. These Bolivian basalts, which may have covered an initial surface of ~ 30,000 km2, represent the known southernmost occurrence of the CAMP. They were erupted as a single pulse, more than 8000 km away from the northern edge of the province. We discuss the implications of such a huge elongated CFB for the current plume models and we suggest, as an alternative, that large-scale melting beneath the Pangea supercontinent due to mantle global warming could have triggered the emplacement of the CAMP.

    Navarin Basin, scheduled for leasing in 1984 (OCS sale 83), may contain vast accumulations of oil and gas. Several geologic and oceanographic processes that may be active in and around Navarin Basin province could be hazardous to commercial development. These potential hazards include submarine slides; sea-floor instability resulting from disturbance of gas-charged sediment; sediment transport and erosion caused by storm waves, tsunamis, internal waves, or bottom currents; pack ice; and active faults and ground motion.

    Slip rates and slip vector azimuths on major active oblique normal faults are used to investigate whether circulation associated with the Yellowstone upwelling plume is driving tectonic deformation in the northeast Basin and Range province. Observed deformation is consistent with this suggestion; the plume is sheared to the southwest by motion of the North American plate. Testable predictions are made for structure and evolution of the region.

  20. ‘Large Igneous Provinces (LIPs)’: Definition, recommended terminology, and a hierarchical classification

    NASA Astrophysics Data System (ADS)

    Sheth, Hetu C.

    2007-12-01

    This article is an appeal for the adoption of a correct and appropriate terminology with respect to the so-called Large Igneous Provinces (LIPs). The term LIP has been widely applied to large basaltic provinces such as the Deccan Traps, and the term Silicic Large Igneous Province (SLIP) to volcanic provinces of dominantly felsic composition, such as the Whitsunday Province. However, neither term (LIP, SLIP) has been applied to the large granitic batholiths of the world (e.g., Andes) to which both terms are perfectly applicable. LIP has also not been applied to broad areas of contemporaneous basalt magmatism (e.g., Indochina, Mongolia) and sizeable layered mafic intrusions (e.g., Bushveld) which in many significant respects may also be considered to represent 'Large Igneous Provinces'. Here, I suggest that the term LIP is used in its broadest sense and that it should designate igneous provinces with outcrop areas ≥ 50,000 km 2. I propose a simple hierarchical classification of LIPs that is independent of composition, tectonic setting, or emplacement mechanism. I suggest that provinces such as the Deccan and Whitsunday provinces should be called Large Volcanic Provinces (LVPs), whereas large intrusive provinces (mafic-ultramafic intrusions, dyke/sill swarms, granitic batholiths) should be called Large Plutonic Provinces (LPPs). LVPs and LPPs thus together cover all LIPs, which can be felsic, mafic, or ultramafic, of sub-alkalic or alkalic affinity, and emplaced in continental or oceanic settings. LVPs are subdivided here into four groups: (i) the dominantly/wholly mafic Large Basaltic Provinces (LBPs) (e.g., Deccan, Ontong Java); (ii) the dominantly felsic Large Rhyolitic Provinces (LRPs) (e.g., Whitsunday, Sierra Madre Occidental); (iii) the dominantly andesitic Large Andesitic Provinces (LAPs) (e.g., Andes, Indonesia, Cascades), and (iv) the bimodal Large Basaltic-Rhyolitic Provinces (LBRPs) (e.g., Snake River-High Lava Plains).

    There is a profound debate over how to assign greenhouse gas (GHG) responsibilities; therefore, we have decided to follow IPCC guidelines, as they offer the only standardized method. We have identified each type of greenhouse emission and its level of absorption. We have studied the province and its districts and municipalities. We have determined that the energy sector is that with the highest level of emissions, even if the per capita emissions of the Province of Siena are very low. This is caused by a very low level of industrialization and the presence of a local geothermal production of energy. In order to highlight this aspect, we have considered scenarios both with and without geothermal production. Our research was then focused on single districts (groups of homogenous municipalities) and municipalities, where we found great differences among the greenhouse emissions of the areas. We have constructed a map of the greenhouse emissions of the whole province. It has been interesting to note that there are 14 municipalities with net negative emissions, seven with low positive emissions, 12 with medium positive emissions and three with elevated positive emissions. These latter correspond to the main city and to two of the most industrialized municipalities.

    To assess the incidence and associated signs and symptoms of patients with keratoconus in Asir Province, Saudi Arabia. 125 new keratoconus patients (51 male, 74 female; mean age 18.5 (SD 3.8) years; range 8--28 years) were recruited from referrals to the department of ophthalmology, Asir Central Hospital, over a 1 year period. Age, visual acuity, and keratometry were recorded along with clinical signs and symptoms. The incidence of keratoconus in Asir Province is 20 cases per 100,000 population. Also, the disease severity is high, as indicated by an early mean age (17.7 (3.6) years) with advanced stage keratoconus. Visual acuity, with either spectacles or rigid contact lenses, was 6/12 or better in 98% of eyes measured. Just over half (56%) of patients had atopic ocular disease. 16% of patients had a positive family history of the disease and 16% had atopic dermatitis (eczema and/or vitiligo). The incidence and severity of keratoconus in Asir Province, Saudi Arabia, is high with an early onset and more rapid progress to the severe disease stage at a young age. This might reflect the influence of genetic and/or environmental factor(s) in the aetiology of keratoconus.

    With the rapid growth of the world population that is becoming increasingly the use of motor vehicles. Also, due to technological advances that have become more accessible to a case having a motor vehicle. However, these developments have led to the emergence of some problems. Especially, highways of serious accidents occurred in transportation, to investigate measures that can be taken and identification of the problem is an important issue in Turkey. First, you need to identify the individual's perception of traffic. This process is important to identify gaps in the application. This study was planned and carried out in order to measure the traffic perceptions of living in Eskisehir Province. For this purpose, a questionnaire aimed at determining demographic and socio-economic characteristics and attitudes of the individual's perception of traffic was prepared. Data sets were analysed by factor analysis known as one of the most known multivariate statistical analysis techniques. The result of analysis obtained over the dimensions, traffic perceptions of individual's in Eşkisehir Province modelled. Looking for solutions for the traffic problem in institutions of the Eşkisehir Province has obtained a series of results that could benefit in creating attitudes and behaviours about traffic.

    Brackish-water mollusks inhabiting the mangrove areas along the Gulf of Thailand of Surat Thani Province were investigated for distribution, abundance and natural infections. Nine families and 32 species of brackish-water snails were recovered from 14 sampling stations. Species belonging to the genus Ceritidea of the family Potamididae were mainly examined and Cerithidea (Cerithideopsilla) Cingulata, C. (C.) djadjariensis, and C. (Cerithidea) charbonnieri were naturally infected with 2 types of trematode cercariae, and one which was undetermined. C. (C.) cingulata had the highest infection rate (38.5%). Viewing two snail communities, the first community on the mainland and the second on Samui Island in Surat Thani Province, 28 brackish-water mollusk species were present on the mainland, 15 species were evident on Samui Island, and 11 snail species were common to both the mainland and Samui Island. Measurement of community similarity based on species presence revealed an index of similarity of 0.51. Concerning land use by the local people in the station areas investigated, brackish-water snails in Surat Thani Province are facing habitat degradation by human use.

The aimed of this program is to speed up Electrification Rate (ER) with priority to the six provinces at Eastern area of Indonesia including Papua Province. The target of Indonesian's ER by 2019 is 97%. While the Indonesian's national ER already high (88.30%) in 2015, Papua still the lowest ER (45.93%) among the provinces. The scenario to boost up ER in the Eastern area by connected the consumers at villages which not electrified yet to the new Renewable Energy sources. This paper presents an overview of current situation of Electricity Infrastructure and Operation particularly on the mountain area which has high populated compare to coastal area but the average RE below 10%. Case studies of electricity infrastructure profile from mountain area were conducted to identify and reveal the challenge to achieve the Bright Indonesia objectives. Also, the assessment of the visibility according to the high target from this program will be presented.

On the platform of the currently available databases for academic science journals (Wanfang Datebase, China Acdemic Journal Network, PubMed and SCI) with the assistance general searching engines, the websites of the medical journals in Guangdong province were evaluated and the editorial offices of the core medical journals in Guangdong province were interviewed. At present, the internet-based publication of the journals was executed predominantly by 3 means, namely utilization of the access to the websites of the direct sponsor, authoritative websites of science and technology, or independent websites. Relying on the database system of Wanfang and China Academic Journal Network, for instance, most of the journals can provide access to their full-text resources, but this internet-based publication is somehow delayed in comparison with the print publication. At present, only a few medical journals in Guangdong have built their independent websites, and among those which already have, Journal of First Military Medical University and Cancer are indexed by IM and PubMed, therefore they provide online abstracts of the papers ahead of the print copy publication.

    It is done a cross-sectional study of the prevalence of mental retardation in the province of Jaén (Spain), based on the cumulated cases reported to the Institute of Social Services of the Social Security (INSERSO) until January 1, 1984. The main objective of this research is to know the prevalence of mental retardation in our province, and to analize its relationship with some sociodemographic variables. The prevalence obtained has been 4.09%, being a 59.27% of the prevalence due to endogenous/unexplained etiology. Mild subnormality constitutes a 8.4% of cases, being closely related with the size of the locality (municipio). Prevalence of mental subnormality showed a significative linear association with the size of the locality (r = -0.904, p less than 0.05), and with the population growth (r = -0.929, p less than 0.01). This relationship was not observed neither with the level of per capita income nor the altitude of the locality. A multiple regression analysis is made for every etiology of mental retardation and several social and geographic variables. We conclude that the figures for mental retardation in our province show a direct relationship with local development parameters.

    Objective This study investigated the incidence of gestational trophoblastic disease (GTD) in Tokat province, Turkey. Material and Methods The medical records of patients who had been diagnosed and treated at one university hospital, six government hospitals, and one specialist hospital in Tokat province between January 2005 and December 2012 were evaluated retrospectively. Results During the study period, there were 59,754 births and GTD was diagnosed in 73 cases. The calculated GTD incidence was 1.22/1000. The mean age of the patients diagnosed with GTD was 28.6±7.3 (range 17–51) years. In GTD, complete moles occurred in 26%, partial moles in 74%, and no invasive moles, choriocarcinomas, or placental site trophoblastic tumours were found. Only two patients received chemotherapy (methotrexate). There was no mortality associated with the disease during follow-up. Conclusion The incidence of GTD in Tokat province was 1.2 per 1000 births. Early diagnosis, treatment, and follow-up play a critical role in preventing the morbidity and mortality associated with disease. The incidence of GTD, which has a high recovery rate with adequate treatment and follow-up, can be determined from regional and community-based research. PMID:24790512

According to World Health Organization (WHO), the number of human cases is not known precisely. Available reports showed that worldwide incidences vary from 0.1-1 per 100 000 per year in temperate climates to 10-100 per 100 000 in the humid tropics. Pathogenic bacteria that is spread by the urines of rats is the main reason of water and soil infections. Rice field farmers who are in contact with infected water or soil, contain the most burden of leptospirosis prevalence. In recent years, this zoonotic disease have been occurred in north of Iran endemically. Guilan as the second rice production province (average=750 000 000 Kg, 40% of country production) after Mazandaran, has one of the most rural population (Male=487 679, Female=496 022) and rice workers (47 621 insured workers) among Iran provinces. The main objectives of this study were to analyse yearly spatial distribution and the possible spatial clusters of leptospirosis to better understand epidemiological aspects of them in the province. Survey was performed during the period of 2009-2013 at rural district level throughout the study area. Global clustering methods including the average nearest neighbour distance, Moran's I and General G indices were utilized to investigate the annual spatial distribution of diseases. At the end, significant spatial clusters have been detected with the objective of informing priority areas for public health planning and resource allocation.

    Atmospheric nitrogen deposition is an essential component of acid deposition and serves as one of main sources of nitrogen of the ecosystem. Along with rapidly developed economy, it is expected that the nitrogen deposition in Guangdong province is considerably large, due to substantial anthropogenic reactive nitrogen lost to the Pearl River Delta (PRD) region, one of the most developed region in China. However, characterization of chemical compositions of inorganic nitrogen (IN) deposition and quantification of nitrogen deposition fluxes in time and space in Guangdong province were seldom conducted, especially using a numerical modeling approach. In this study, we established a WRF/SMOKE-PRD/CMAQ model system and expanded 2006-based PRD regional emission inventories to Guangdong provincial ones, including SO2, NOx, VOC, PM10, PM2.5, and NH3 emissions for modeling nitrogen deposition in Guangdong province. Observations, including meteorological observed data, rainfall data, ground-level criteria pollutant measurements, satellite-derived data, and nitrogen deposition fluxes from field measurements were employed in the evaluation of model performance. Results showed that annual nitrogen deposition fluxes in the PRD region and Guangdong province were 31.01 kg N hm-1 a-1 and 26.03 kg N hm-1 a-1, dominated by NHx (including NH3 and NH,SUB>4,/SUB>+), with a percentage of 63% and 71% of the total deposition flux of IN, respectively. The ratio of dry deposition to wet deposition was approximately 2:1 in the PRD region and about 3:2 in the whole Guangdong province. IN deposition was mainly distributed in the PRD region, Chaozhou, and Maoming, which was similar to the spatial distributions of NOx and NH3 emissions. The spatial distributions of chemical compositions of IN deposition implied that NH3-N and NOx-N tended to deposit in places close to emission sources, while spatial distributions of aerosol NH4+ -N and NO3- -N usually exhibited broader deposition areas, along with

    As a general rule it is accepted that every change in the environment is controlled by the changes in the pressure patterns or varying synoptic systems. We are witnessing intensive floods, damaging cold waves, or highly polluted air every year, all of which are related to some extent to the pressure patterns such as intensive cyclones or subsiding anticyclones. The frost days are one of these environmental conditions that are caused by these pressure patterns especially in the case of synoptic frosts. The Zanjan province of Iran with mountainous nature and higher elevations is one of the frost prone regions in the country. Most of the years this region suffers from intensive and damaging frosts such as the one occurred in December 2006 and January 2007. In order to advise planners and users, and lower the damages of such frosts, this study tried to analyze the synoptic origin of the December 2006 frost. To achieve the objective of the study the frost days of the province during months December 2006 and January 2007 were selected. During these months all of the four stations of the Province ( Zanjan, Khorramdarreh, Khodabandeh, and Mahneshan) had experienced sub-zero temperatures. The daily zero GMT surface and 500 hPa. maps of the region were extracted from the National Center of Environmental Protection (NCEP) site for the selected days. The pressure patterns of both levels were analyzed and assigned into different groups. The results showed that the main synoptic patterns responsible for the frosts of the region are the Caspian trough, Siberian high pressure, moving western anticyclones, upper level blockings, and cut off lows. When the Caspian Sea trough deepens it brings the westerly anticyclones to the area. Under its eastward displacement, the Siberian High develops and sends its ridges towards the study region. Some times the upper level blocking of the Siberian area brings the cold air masses to the study region. In general, the development and displacement

    To understand the epidemic situation and influencing factors of malaria in Jiangsu Province and grasp the regularity and trend of the epidemic. According to the provincial malaria transmission situation and characteristics, Sihong County of Suqian City, which had more original cases, and Baoying County of Yangzhou City, which had more import cases, were chosen as the malaria surveillance sentinels at the state level; six counties, Yixing County of Wuxi City, Suining County of Xuzhou City, Wujin District of Changzhou City, Haian county of Nantong City, Ganyu County of Lianyugang City, and Xuyi county of Huaian City were chosen as the malaria surveillance sentinels at the provincial level. The data of basic status, blood tests of feverish patients, case studies of malaria patients, investigations and disposals of epidemic focuses and others were collected and analyzed. There were 92,484 blood test samples from feverish patients in the eight surveillance sentinels in 2014, and the average rate of blood tests was 1.15%. Totally 61 cases were plasmodium positive, and the positive rata was 0.07%. All of the 61 cases were foreign imported patients diagnosed by laboratory. After the direct network reporting, the review of the blood slides and epidemiological individual surveys were finished in 3 days, and the investigations and disposals of epidemic focuses were finished in 7 days. The epidemiological individual surveys of these 61 cases showed that 37.70% (23/61) of the first-time consultancy was mainly in the county level CDC, and 50.82% (31/61) in county level medical organizations. The making definite diagnosis of malaria also focused on the county level, 45.90% (28/61) in county level CDC and 47.10% (29/61) in county level medical organizations. The definite diagnostic rate of fist-time consultancy was 90.16% (55/61). Totally 48 malaria patients had been sent to abroad by their companies, and 34 had fellow crew.

    Ecological security can be investigated in both broad sense and narrow sense. Because of the wide area and regional discrepancy in influencing factors and ecological background, the investigation on regional environment hasn't been done systematically. Assessment on regional security in fragile region is important content of sustainable development. The western Jilin Province lines in the semi-arid agro-pastoral interweaving belt (APIB),within which agriculture and animal husbandry interplay or frequently alternate with each other. Study on the regional ecological security of this region offer the scientific support for protecting the regional environment and sustainability. This article set up the Pressure-State-Response model according to the interaction between human and environmental system, and assessed the ecological safety degree in the western part of Jilin Province in year 2000, using compound model and Grid method based on GIS and RS. The Ecological Security Index (ESI) was calculated by multilayer synthesis with liner weighting function method, which divided the area into the following five different conditions: highly damaged, moderately damaged, early stages of damage, relative safely, and safety, regarding change of environmental key point as the threshold value that varied under the stress of human activity. The results show that eco-environment in study area is at medial level. The early stage of damage and relative safely level occupies the largest area proportion accounting for 68.61%. Furthermore, the condition in the eastern part is better than that of the western part and the most serious degradation is found in the middle part of the study area. When talking about the ten counties in the region, highly damaged area accounts for a very small percentage. The county that has the widest area of relatively secured area is Qian'an, and that of the smallest is Da'an. The areas of highly damaged area in Tongyu, Zhenlai and Da'an have exceeded 10% and

    Objective: To investigate the prevalence, awareness, treatment and control rate of hypertension among Dongxiang population of Dongxiang county in Gansu province, and analyze risk factors of hypertension in this population. Methods: A total of 1 879 Dongxiang residents of Dongxiang county in Gansu province aged 18 years and over were selected in one town and eight villages by random cluster method from April to June in 2014. All subjects were interviewed and physical examination including blood pressure measurement was performed. Multivariate logistic regression analysis was used to analyze the risk factors of hypertension. Results: Prevalence of hypertension in this population was 21.4%(402/1 879). Prevalence of hypertension increased with aging and was 7.9%(35/441) in 18-39 years old people, and 20.2%(151/749)in 40-59 years old people, and 31.3%(216/689)in ≥60 years old people (P<0.01). There were no gender (male vs. female) difference in prevalence of hypertension in 18-39 years old group (8.0%(20/249)vs. 7.8%(15/192), P>0.05) and 40-59 years old group (19.8%(78/393) vs. 20.5%(73/356), P>0.05), while the prevalence of hypertension was significantly higher in male than in female(34.2%(123/360) vs. 28.3%(93/329), P<0.01)in ≥60 years old group. Prevalence of hypertension was also significantly higher in rural area residents than in county town residents (23.4%(255/1 090) vs.18.6%(147/789), P<0.01). The rates of awareness, treatment and control of hypertension in this population were 24.4%(98/402), 14.7%(59/402) and 5.0%(20/402), respectively. Rates of awareness (22.7%(58/255)vs. 27.2%(40/147), P<0.01), treatment(13.3%(34/255)vs. 17.0%(25/147), P<0.05) and control(3.9%(10/255)vs. 6.8%(10/147), P<0.05) were significantly lower in rural area residents than in county residents. Multivariate logistic regression analysis showed that age, family history of hypertension, high body mass index, less physical activity and more static state were risk factors of hypertension

  19. Disaster resilience in tertiary hospitals: a cross-sectional survey in Shandong Province, China

    Background Hospital disaster resilience can be defined as a hospital’s ability to resist, absorb, and respond to the shock of disasters while maintaining critical functions, and then to recover to its original state or adapt to a new one. This study aims to explore the status of resilience among tertiary hospitals in Shandong Province, China. Methods A stratified random sample (n = 50) was derived from tertiary A, tertiary B, and tertiary C hospitals in Shandong Province, and was surveyed by questionnaire. Data on hospital characteristics and 8 key domains of hospital resilience were collected and analysed. Variables were binary, and analysed using descriptive statistics such as frequencies. Results A response rate of 82% (n = 41) was attained. Factor analysis identified four key factors from eight domains which appear to reflect the overall level of disaster resilience. These were hospital safety, disaster management mechanisms, disaster resources and disaster medical care capability. The survey demonstrated that in regard to hospital safety, 93% had syndromic surveillance systems for infectious diseases and 68% had evaluated their safety standards. In regard to disaster management mechanisms, all had general plans, while only 20% had specific plans for individual hazards. 49% had a public communication protocol and 43.9% attended the local coordination meetings. In regard to disaster resources, 75.6% and 87.5% stockpiled emergency drugs and materials respectively, while less than a third (30%) had a signed Memorandum of Understanding with other hospitals to share these resources. Finally in regard to medical care, 66% could dispatch an on-site medical rescue team, but only 5% had a ‘portable hospital’ function and 36.6% and 12% of the hospitals could surge their beds and staff capacity respectively. The average beds surge capacity within 1 day was 13%. Conclusions This study validated the broad utility of a framework for understanding and measuring the

  20. Water consumption of agriculture and natural ecosystems at the Amu Darya in Lebap Province, Turkmenistan

    The Amu Darya is the main water source for whole Turkmenistan, but also for the regions Khorezm and Karakalpakistan in Uzbekistan. Due to the arid climate in the Amu Darya river basin, agriculture depends on irrigation with river water being the major source of water. Also the natural ecosystems depend on river water. Until end of the 1970s, the Amu Darya flew into the Aral Sea and, together with the Syr Darya, sustained its water level. From the 1960s until today the area under irrigation has been strongly enlarged. During Soviet Union times, mainly cotton was planted on the newly reclaimed land. After independence, new land was reclaimed, in order to grow wheat. In the course of this land reclamation, the downstream section of the Amu Darya, i.e. in Karakalpakistan faces severe water shortage. Today, the Amu Darya only occasionally reaches the previous shore line of the Aral Sea. Against this background, it is necessary that water consumption along the Amu Darya is limited and water is used efficiently, in order to ensure water supply for downstream water users. The province Lebap in Turkmenistan is located at the middle reaches of the Amu Darya. Thus, it is an example of an administrative unit, which consumes water from the Amu Darya and which should release a sufficient amount of water downstream. Furthermore, Lebap harbours one of the last near-natural riparian forests of Central Asia, i.e. the Amu Darya State Reserve, which also is a water consumer. Therefore, we estimate the water consumption of agriculture (cotton, wheat, rice, and house gardens) and the natural ecosystems within Lebap Province. Water consumption refers to the actual evapo-transpiration. We use Landsat ETM and TM satellite images, in order to produce maps of the actual evapo-transpiration. Afterwards, a land cover map is laid over the ETa maps, in order to retrieve the ETa of the different crops and natural ecosystems. These results are compared with the water norms and quotas given for

    Despite an increasing number of empirical investigations of catchment transit times (TTs), virtually all are based on individual catchments and there are few attempts to synthesize understanding across different geographical regions. Uniquely, this paper examines data from 55 catchments in five geomorphic provinces in northern temperate regions (Scotland, United States of America and Sweden). The objective is to understand how the role of catchment topography as a control on the TTs differs in contrasting geographical settings. Catchment inverse transit time proxies (ITTPs) were inferred by a simple metric of isotopic tracer damping, using the ratio of standard deviation of ??18O in streamwater to the standard deviation of ??18O in precipitation. Quantitative landscape analysis was undertaken to characterize the catchments according to hydrologically relevant topographic indices that could be readily determined from a digital terrain model (DTM). The nature of topographic controls on transit times varied markedly in different geomorphic regions. In steeper montane regions, there are stronger gravitational influences on hydraulic gradients and TTs tend to be lower in the steepest catchments. In provinces where terrain is more subdued, direct topographic control weakened; in particular, where flatter areas with less permeable soils give rise to overland flow and lower TTs. The steeper slopes within this flatter terrain appear to have a greater coverage of freely draining soils, which increase sub-surface flow, therefore increasing TTs. Quantitative landscape analysis proved a useful tool for intercatchment comparison. However, the critical influence of sub-surface permeability and connectivity may limit the transferability of predictive tools of hydrological function based on topographic parameters alone.

    Groundwater recharge is the primary source of aquifer replenishment, an important source of freshwater for human consumption and riparian area sustainability in semi-arid regions. It is critical to understand the current groundwater recharge regimes in groundwater basins throughout the Western U.S. and how those regimes might shift in the face of climate change, land use change and management manipulations that impact the availability and composition of groundwater resources. Watersheds in the Basin and Range Province are characterized by a variable precipitation regime of wet winters, and variable summer precipitation. The horst-graben structure of these basins lends itself to orographic and continental precipitation effects that make mountain block and mountain front recharge critical components of annual recharge. The current assumption is that the relative contributions to groundwater recharge by summer and winter precipitation vary throughout the province, with winter precipitation dominating in the northern parts of the region, and summer monsoonal precipitation playing a more significant role in the south, where the North American Monsoon extends its influence. To test this hypothesis, stable water isotope data of groundwater and precipitation from sites in Sonora, Mexico and the U.S. states of California, Nevada, Utah, Arizona, Colorado, New Mexico, and Texas were examined to characterize and compare groundwater recharge regimes throughout the region. Preliminary stable water isotope results from the southernmost Rio San Miguel Basin in Sonora, Mexico indicate that groundwater is composed of 64%±14% summer monsoon precipitation, in contrast to more northern basins where winter precipitation is the source of 79-90% of basin groundwater.

    The effects of salt mobilization on Aptian and younger (post-112 Ma) strata in the East Texas basin can be used to illustrate patterns of dome growth through time, and to estimate rates and amounts of salt movement. Pre-Aptian domes grew in three areas around the margin of the diapir province, apparently in pre-Aptian depocenters. Maximum dome growth along the basin axis coincide with maximum regional sedimentation there during the middle Cretaceous (Aptian, Albian, and Cenomanian). In the Late Cretaceous the sites of maximum diapirism migrated to the periphery of the diapir province. Diapirism began after pillows were erosionally breached, leading to salt extrusion and formation of peripheral sinks. The duration of pillow and diapir stages of growth was subequal, ranging from 10 to 30 Ma. Post-diapiric stage of growth continued for more than 112 Ma in some cases. Diapirs grew fastest in the Early Cretaceous, when peak growth rates ranged from 150 to 530 m/Ma (490 to 1740 ft/Ma), declining in the Early Tertiary to 10 to 60 m/Ma (30 to 200 ft/Ma). Assuming steady-state conditions over periods of 1 to 17 Ma, strain rates for the rise of the East Texas diapirs averaged 6.7 X 10/sup -16/ sec;peak gross rate of growth averaged 2.3 X 10/sup -15/ sec, similar to slow orogenic rates. The evolution of East Texas salt domes essentially ended in the early Tertiary with uplift rates less than 30 m/Ma (100 ft/Ma).

    Since ancient times in South Tyrol there was evidence of endemic goitre caused by iodine deficiency. In the early 80's an epidemiological research on adults and primary and secondary school children reported in the least a prevalence of goitre from grade 1 B-3 (WHO) of 23,66% (limits WHO >5%) and an urinary iodine of 10,2 µgI/L. Therefore South Tyrol population presented heavy endemic goitre. In 1982 started a generalized iodine prophylaxis with alimentary iodined salt after an intense prevention campaign. In 1990 it has been done another epidemiological research on primary and secondary school children of the province (neck palpation, thyroid ultrasound, blood and urine tests) which revealed a prevalence of goitre from grade 1 B (WHO) of 1,6% (limits WHO >5%) and an urinary iodine of 137,1 µgI/L. Therefore in South Tyrol there was no more evidence of endemic goitre. In 2001 another research over primary and secondary school children, of the same areas and with the same approaches of the previous researches reported a prevalence of goitre of 1,5% and a median of urinary iodine of 230 µgI/L. On the basis of the data of Istituto Superiore di Sanità (National Institute of Health) can be stated that in the Province of Bolzano there's a low presence of congenital hypothyroidism. It has been observed an increase in the thyroiditis and in the diagnosis of thyroid cancer was marked an accentuation of papillar forms, less aggressive than the follicula. Unfortunately since 2001 no new epidemiological researches were done, due to lack of financial resources and the raising of other sanitary problems of higher priority.

    To have a drug listed in a province's formulary, manufacturers must submit an application providing data required by the provincial rules and guidelines. The procedures for the scientific evaluation of drugs considered for listing for reimbursement in five provinces have been examined previously. The present study investigates the clarity of the same five provinces' rules and guidelines about effectiveness and cost data that should be included in listing submissions from the perspective of the pharmaceutical company. The manufacturers of five recently introduced drugs selected by the investigators received questionnaires asking about the departments within their companies that are responsible for the submission, the data required by each of the five provinces and the clarity of each province's requirements for submission. Each company was also asked similar questions about its own submission experience with its drug. Investigators visited each manufacturer to review the questionnaires and answer questions. The manufacturers perceived the rules and guidelines on effectiveness and economic data of several provinces as being neither clear nor consistent. Consequently, information that companies submit in their attempts at compliance with the rules and guidelines varies substantially. The manufacturers' perceptions of the information required by the provinces on effectiveness and cost information were inconsistent. Previous work indicated that the provinces make significant decisions about listings based on inadequate information resulting in a scientifically flawed system that contributes to considerable inequality in access to new drugs between provinces. The findings of the present work reinforce this conclusion.

    Recently, we reported that the frequency of hepatitis C virus (HCV) genotypes and subtypes has rapidly changed among intravenous drug users (IDUs) in Yunnan Province over the last 5 years; this is especially true for subtype 6a which has increased in frequency from 5 to 15%. Here, we assessed 120 HCV-positive plasma samples from the general population (GP). HCV NS5B fragments were amplified and sequenced by PCR. We identified four HCV genotypes (1, 2, 3 and 6) and seven HCV subtypes (1b, 2a, 3a, 3b, 6a, 6n, and 6k) in this population. Genotype 3 was predominant, with a distribution frequency of 0.484, followed by genotype 1 (0.283), genotype 6 (0.133) and genotype 2 (0.100). HCV subtypes 3b (frequency 0.292) and 1b (frequency 0.283) were the most common subtypes. A comparison of the current data with previous results reported for IDUs showed that the distribution frequencies of genotypes 1, 2 and 6 were significantly different between patients in the GP and IDUs (P < 0.05). Among the HCV subtypes, the distribution frequencies of 1b, 2a, 6a, and 6n were significantly different between patients in the GP and IDU groups (P < 0.05). Moreover, Phylogenetic analyses showed that HCV subtype 6a strains isolated from IDUs and the GP were intermixed and not separately clustered. HCV subtype 6a was predominant not only among IDUs but also among those in the GP in the Guangdong Province and Vietnam. However, HCV subtype 6a was predominant only among IDUs and not among those in the GP in the Yunnan and Guangxi Provinces. Our results indicate that the HCV subtype 6a could rapidly spread across China.

    We attribute most of the development of extensive fractures in the Tharsis region to discrete tectonic provinces within the region, rather than to Tharsis as a single entity. One of these provinces is in Syria Planum. Faults and collapse structures in the Syria Planum tectonic province on Mars are grouped into 13 sets based on relative age, areal distribution, and morphology. According to superposition and fault crosscutting relations and crater counts we designate six distinct episodes of tectonic activity. Photoclinometric topographic profiles across 132 grabens and fault scarps show that Syria Planum grabens have widths (average of 2.5 km, and most range from 1 to 6 km) similar to lunar grabens, but the Martian grabens have slightly higher side walls (average abour 132 m) and gentler wall slopes (average of 9?? and range of 2??-25??) than lunar grabens (93 m high and 18?? slopes). Estimates of the amount of extension for individual grabens range from 20 to 350 m; most estimates of the thickness of the faulted layer range from 0.5 to 4.5 km (average is 1.5 km). This thickness range corresponds closely to the 0.8- to 3.6-km range in depth for pits, troughs, and canyons in Noctis Labyrinthus and along the walls of Valles Marineris. We propose that the predominant 1- to 1.5-km values obtained for both the thickness of the faulted layer and the depths of the pits, troughs, and theater heads of the canyons reflect the initial depth to the water table in this region, as governed by the depth to the base of ground ice. Maximum depths for these features may indicate lowered groundwater table depths and the base of ejecta material. -from Authors

    Background Accidents are the most important public health challenges in our society. To prevent the accidents, the identification of their epidemiological features seems necessary. Objectives This study was conducted to reveal the epidemiological features of accidents and their casualties in Qom province in 2010. Patients and Methods A cross–sectional study was conducted on 29426 injured people referred to Qom province hospitals in 2010. Information about place, time, type of accidents and traumas and demographic variables had been collected in a veteran hospital. Data were analyzed by SPSS (version 16) software, using chi-square test and logistic regression. Results The incidence of accidents was about 27/1000 per year. The incidences of traffic accidents, motorcycle accidents, violence, burns, poisoning and suicides were 3, 1.6, 1.2, 0.3, 0.8, 0.37 cases per 1000 people respectively. Strikes (65%) and falls (12%) were the main causes of traumas. Forty-six percent of all injuries had occurred in 16 - 30 years groups. Most frequent accidents were as follows: fall (97%) and strike (50%) in < 12, violence (46%) in 20 - 29, suicide (71%) in 15 - 29, poisoning (34%) and burns (20%) among < 5 years old. Pedestrian and motorcycle accidents among +60 years old people were significantly higher than other (P = 0.000). Odds ratio for suicide among female was about 3.36 and in 16 - 30 age-group was 15.7 more than +60 years old group (P = 0.000). Conclusions Most traumas in Qom province occurred among younger age-groups and strikes and falls are the main causes of such traumas. Therefore, safeties to prevent falls and traffic regulations to reduce strikes can be effective strategies. PMID:24693520

    Events of severe air pollution occurred frequently in China recently, thus understanding of the air pollution characteristics and its health risks is very important. In this work, we analyzed a two-year dataset (March 2014 - February 2016) including daily concentrations of six criteria pollutants (PM2.5, PM10, CO, SO2, NO2, and O3) from 18 cities in Henan province. Results reveal the serious air pollution status in Henan province, especially the northern part, and Zhengzhou is the city with the worst air quality. Annual average PM2.5 concentrations exceed the second grade of Chinese Ambient Air Quality Standard (75μg/m(3)) at both 2014 and 2015. PM2.5 is typically the major pollutant, but ozone pollution can be significant during summer. Furthermore, as the commonly used air quality index (AQI) neglects the mutual health effects from multiple pollutants, we introduced the aggregate air quality index (AAQI) and health-risk based air quality index (HAQI) to evaluate the health risks. Results show that based on HAQI, the current AQI system likely significantly underestimate the health risks of air pollution, highlighting that the general public may need stricter health protection measures. The population-weighted two-year average HAQI data further demonstrates that all population in the studied cities in Henan province live with polluted air - 72% of the population is exposed to air that is unhealthy for sensitive people, while 28% of people is exposed to air that can be harmful to healthy people; and the health risks are much greater during winter than during other seasons. Future works should further improve the HAQI algorithm, and validate the links between the clinical/epidemiologic data and the HAQI values. Copyright © 2017 Elsevier Inc. All rights reserved.

    The emergence of drug-resistant tuberculosis (TB) hampers TB control. Ten provinces in China performed drug resistance surveys among tuberculosis (TB) patients in 1996-2004 to assess levels of drug resistance. Provincial drug resistance surveys included all isolates from newly diagnosed, smear-positive TB patients. Drug susceptibility testing (DST) against isoniazid, rifampicin, streptomycin and ethambutol was carried out in the provincial laboratories. For purposes of quality assurance, a random sample (11.6%) was re-tested by the national reference laboratory (NRL). Of 14,059 patients tested 11,052 (79%) were new TB cases. The weighted mean prevalence of multi-drug resistant tuberculosis (MDR-TB) among all cases was 9.3% (range 2.2%-10.4%); 5.4% (range 2.1% - 10.4%) among new cases and 25.6% (range 11.7%-36.9%) among previously treated cases. Adjusting the drug resistance proportions using the re-testing results did not change the estimated national mean prevalence significantly. However, in some individual provinces the estimated resistance proportions were greatly influenced, especially among re-treatment patients. MDR-TB levels varied greatly between provinces in China, but on average were high compared to the global estimated average of 4.8%. This study shows the importance of quality-assured laboratory performance. Programmatic management of drug-resistant TB, including high quality DST for patients at high risk of resistance and treatment with second-line drugs, should become the standard, especially in high MDR-TB settings.

    To explore the trends in blood collection from 2006 to 2014 in Guangdong, China. Although the Blood Donation Law of the People's Republic of China was implemented in 1998, voluntary non-remunerated blood donation (VNRBD) has been promoted fully for only a decade. The provincial and local governments of Guangdong, one of the most well-developed provinces in China, have promoted blood donation by various means. Official data on blood donation from 2006 to 2014, including the number of blood donations and the family replacement/mutual blood donation (FRMBD) rate, were collected from all blood collection and supply institutions in Guangdong. These data were analysed to explore trends in blood donation in Guangdong Province, and to detect differences among the province's four regions. The number of blood donations in Guangdong increased by 38·23% from 2006 to 2014; overall, the rate increased annually, although it fluctuated in the eastern region. Family replacement/mutual whole blood and platelet donation rates decreased dramatically from 2006 to 2014 (from 39·99% to 20·16% and from 64·15% to 26·51%, respectively), but remained high. Marked disparities in blood donation development were detected among the four regions. With nearly a decade of efforts, blood donation in Guangdong has developed rapidly and sustainably. All blood collection and supply institutions must strengthen efforts to improve awareness of blood donation among the population, retain repeat and regular donors and reduce the rate of FRMBD in favor of the development of VNRBD. © 2016 British Blood Transfusion Society.

    This research aims at identifying relative interventions on trachoma and testing the effectiveness of control measures adopted by assessing its prevalence and related risk factors in Shandong province of China. Trachoma rapid assessment (TRA) was conducted in 6 sub-districts selected from Shandong province based on primary high risk assessment. Active trachoma in children aged 1-9 years and environmental risk factors of trachoma (unclean faces, absence of running water, and absence of flush toilets) were assessed (TRA 1). Control measures were taken in endemic areas. A second TRA (TRA 2) was conducted after 12 months in the same 6 districts and findings of the two TRAs were compared. In TRA 1, we found trachoma in 3 sub-districts and the detection rate was 4% (95% CI: 0.39%-11.12%), 6% (95% CI: 1.18%-14.17%), and 6% (95% CI: 1.18%-14.17%) respectively. We could not find trachoma cases in TRA 2. Research data supports that children living with environmental risk factors face an increased risk to active trachoma. However, we could not find statistical evidence for this association, which may be caused by the limited data on prevalence. This research indicates that the TRA methodology is easy to assess trachoma and its related risk factors. Based on the results of this study, we have already achieved the goal of "elimination of trachoma" in Shandong province, as the detection rate of trachomatous inflamation follicular/trachomatous inflammation intense in 1-9-year-old children was less than 5%.

    Henan Province (population, 90 million) in China has nonstable endemic malaria. After 1970 when 10.2 million cases of malaria were reported in the province, a huge control programme was undertaken, and in the mid-1980s indoor spraying and bednet impregnation with pyrethroids began. By 1992 only 318 cases were reported. In 1992 Henan declared "basic elimination of malaria" and in consequence spraying and bednet impregnation ceased after 1994. Subsequently, malaria broke out again in southern Henan. In 1995 we conducted a household survey for malaria transmission in southern Henan. Blood smears and serum samples for immunofluorescent antibody (IFA) testing were collected from 2329 people and 3.1% (73/2329) were positive for infection with Plasmodium vivax and 13% (301/2329) positive for malaria (titre > or = 1:20). All age groups were affected. Exophilic Anopheles sinensis occurs throughout the province; endo-anthropophilic A. anthropophagus, whose vectorial capacity is 20 times greater than that of A. sinensis, occurs mainly in southern Henan (S of latitude 33 degrees N) and was greatly reduced in numbers during 1985-92. Comparison of 1995 entomological data with historical data showed that A. anthropophagus increased in proportion to other anophelines after spraying activities and impregnation of bednets ceased. Over 10% of 9377 residents reported having malaria. The true number affected among the at-risk population of 700,000 must be larger. We conclude that impregnated bednets and malaria surveillance should continue even after an area is declared to have "basically eliminated" malaria. PMID:9744246

    Joint Venture schemes based on the floppy irrigation technology are being promoted in the post-Apartheid South Africa's Limpopo Province. Access to land and water resources in South Africa are largely viewed as a mechanism for re-dressing the Apartheid injustices. This research was part of a broader applied research to help inform irrigation practise in the Limpopo Province. The research used literature review, key informant interviews and a questionnaire survey. The overall research question sought to understand how the Joint Venture Schemes had benefited the smallholder farmers. This paper argues that the joint venture partnership created a new injustice. Firstly, the Joint Venture Scheme design is fundamentally a bad idea which disempower farmers not only to water access but also land as well. The choice of the 'efficient' floppy irrigation technology was made by the state and entailed that land had to be managed as a single unit. In order to make more effective use of this highly sophisticated new technology, the smallholder farmers also needed to go into a joint venture partnership with a white commercial farmer. By virtue of signing the Joint Venture agreement the farmers were also forfeiting their land and water rights to be used for crop production. The smallholder farmers lost access to their water and land resources and were largely relegated to sharing profits - when they exist - with hardly any skills development despite what was initially envisaged in the Joint Venture partnership. Secondly, the implementation of the JVS has been skewed from the start which explains the bad results. This paper further shows how the negative outcomes affected women in particular. As the smallholder farmers argue the technological options chosen by the state have excluded both male and female farmers from accessing and utilising their land and water resources in order to improve their livelihoods; it has entrenched the role of the state and the private interests at the

    Objectives: To estimate the Disabled-adjusted Life Years (DALYs) of Road Traffic Accidents in patients referred to hospitals in Yazd Province, central Iran. Methods: This cross-sectional study was conducted in Yazd province during 2010. To calculate the Years of Life Lost (YLL) due to premature death and to calculate the incidence of non-fatal injuries and Years Lost due to Disability (YLD), the data were collected from Yazd death registration system and hospital records. The causes of death and nature of non-fatal injuries were classified using International Classification of Diseases (ICD-10). We estimated Disability Adjusted Life Years (DALYs) on the guidelines of the Global Burden of Disease Study (discount rate: 0.03, age weight: 0.04, constant age weight correction factor: 0.165). Age and sex composition was taken from the National Statistical Center for the year 2010. Results: During 2009, 483 deaths were caused by traffic accidents in Yazd Province, 382 (79.09%) of which were males, and 101 (20.91%) were females. The mortality rates for males and females were 70.98 and 20.15 in 100,000, respectively. The years of life lost due to premature deaths were 15.84/1000 in men and 4.75/1,000 in women. Total YLLs caused by traffic accidents were 10,908 years. The injuries caused by traffic accidents were calculated as 15.21 and 3.73/1,000 in males and females, respectively. The total YLDs was calculated 1.51/1,000. The total burden of Road Traffic Injuries in Yazd province was 12478 years (DALYs), 87.41% of which was due to premature death, and 12.59% was related to disability. Also, 78.32% was lost in males. The age specific peak of burden was in 15-29 year. Conclusion: This study showed that traffic accidents in Yazd impose a high burden. It seems that it is one of the health sector priorities. It is recommended to revise laws on use of motorcycles, especially on helmet use for motorcyclists, enforce strict laws in residential areas, and review social determinant

    The Vojvodina Province in northern Serbia is well known for its intensive field crops production. Over 90 % of total arable land, which represents more than 1500.000 ha, is used for field or vegetable crop production. A grid superimposed on Vojvodina land by means of a GIS tool (GIS ArcView 10) has divided land into 4 × 4 km units, each representing an area of 1600 ha. Total number of 1370 bulked soil samples were taken (0-30 cm depth) from agricultural land and analysed for total mercury content THg. The samples were analysed using Direct Mercury Analyzer DMA 80 Milestone. Quality control was carried out with IRMM BCR reference materials 143R. The aim of this study was to determine the total content of Hg in agricultural soils and its spatial distributions in different parts of Vojvodina Province. The obtained results were within interval 0.008-0.974 mg kg(-1). The average concentration of Hg was 0.068, with median 0.048 mg kg(-1). The correlation was determined between Hg concentration and organic matter content in the soil. Content of Hg coincides with main geomorphological units of Vojvodina Province. Average values of Hg concentrations for soils formatted on different geomorphological units were 0.031 for sandy area with dune fields, 0.048 for alluvial terraces, 0.055 for upper Pleistocene terraces, 0.058 for loess plateaus, 0.083 for mountains and 0.092 mg kg(-1) for alluvial plains. Hg spatial distribution confirmed that most of Vojvodina Province area has geochemical origin of Hg. Higher concentration of Hg on alluvial plains indicated that the origin of Hg near rivers could be from anthropogenic source. The main rivers in Vojvodina have been dammed more than a century ago. Thus, higher concentrations of Hg in their alluvial plains out of narrow dammed zone around the rivers must be related to natural and anthropogenic sources located in their huge catchments. Higher content of Hg in mountain region can be explained by high clay content in

    Nine geophagic material samples were analysed in order to characterise their mineralogical and elemental constituents, and infer on their health threats. Most abundant mineral in the samples was quartz, followed by smectite, kaolinite and muscovite in minor; and microcline, plagioclase, and goethite in trace quantities. Dominant major oxides were SiO2 (43 - 74 wt%) and Al2O3(15 - 19 wt%). Chemical Indices of Alteration (79.37-99.34) and Weathering (94.38-99.92) values suggest moderate to extreme silicate weathering, and alkali and alkaline earth metals depletion. Based on molar proportions of Al2O3, CaO + Na2O, and K2O, weathering trend and mineralogical compositions of the soils showed more advanced argillic alteration with rare earth elements being more concentrated compared to Upper Continental Crust. Excessive amounts of quartz and heavy metals in the geophagic soils represent significant health threats to geophagic individuals, though heavy metals had low biaccessibility values. There is need for soils beneficiation before ingestion.

    1988-07-01

    Simplified maps of the western Cordillera, indicating distribution of metamorphic facies and times of principal recrystallization have been compiled. Despite rearrangement by transcurrent shuffling, general trends are recognizable. Narrow belts of Phanerozoic high-P blue schist, and serpentinized peridotite lie outboard from broad, penecontemporaneous high-T metamorphosed calcalkaline magma-intruded belts bordering the Pacific Ocean, and both are disposed approximately parallel to the present-day North American margin; they represent recrystallized products of mid-Paleozoic and younger subduction zones, Andean-type margins, and exotic island arcs. In contrast, dominant metamorphic mineral parageneses within the continental interior are spatially associated with chiefly mesozonal granitic plutons. Glaucophane schists, eclogites, and large tracts of ophiolitic ultramafics are absent, in part due to selective overprinting of old accretionary margin lithotectonic assemblages by subsequent orogenies, high-T recrystallization, and anatexis. For example, at depth within the California Coast Ranges, high-P phases are currently being destroyed; farther inland, a general paucity of oceanic petrotectonic assemblages is evident, possibly reflecting the differential sinking of dense basaltic/peridotitic units during thermal softening. Preserved metamorphic field gradients reflect the magnitude of subsequent uplift and erosion as well as original PT conditions. Late Mesozoic to mid-Cenozoic recrystallization accompanied earlier crustal thickening + ductile deformation, succeeded by later extension + brittle faulting + mylonitization; Mesozoic-Cenozoic metamorphism involved cratonal rocks in the Mojave-Sonoran Desert, but in Nevada and to the north, eugeoclinal sections were recrystallized. Metamorphic intensity decreases eastward toward the Phanerozoic hinge line. Basement rocks in the Rockies display the effects of shallow level crustal deformation but much less widespread evidence of post-Proterozoic plutonism and regional metamorphism. Initial Pb, Nd, and Sr isotopic compositions and crystallization ages of igneous rocks, in comparison with times of intrusion, recrystallization, and metamorphic facies distributions are compatible with a geologic scenario involving gradual, proximal growth of the ancient continent chiefly southward from the Archean Wyoming craton during early and mid-Proterozoic time, followed by late Proterozoic-Phanerozoic westward development. Accretion involved the incorporation of some exotic, mostly oceanic, outboard terranes. However, continental growth in the western U.S. Cordillera during both Proterozoic and Phanerozoic time periods appears to have been due chiefly to partial fusion and magma ascent above subducting paleo-Pacific lithospheric plates, combined with metamorphic (+ sedimentary) reworking in the forearc + trench + back arc setting, rather than resulting from the amalgamation of preexisting ancient continental fragments.

    Infection control practices which increase the risk of blood-borne virus transmission with associated dental practice in one South African province were studied. All 24 state dental clinics were observed for adequate provision to carry out good infection prevention and control (IPC) practice, 75 staff including dentists, nurses and dental assistants were interviewed to assess IPC knowledge and 23 dental procedures were observed. Significant findings were the difference between knowledge and practice, despite adequate provisions for safe infection control practice. The lack of protective eye wear during a dental procedure, not washing hands between patients, not disassembling an item prior to disinfection or sterilization, and not using a sterile drill for each patient were identified. A rapid method for detection of occult blood was used as a marker for inadequate IPC practice. Contaminated dental items of equipment just prior to patient use in 25% of equipment tested and 37% of surfaces and surrounding areas in the dental clinics and units were recorded. This study concludes that, despite provision for safe dental practice available in state dental clinics, there was a lack of knowledge application in clinical practice. The risk of blood-borne virus transmission in a population with high human immunodeficiency virus (HIV) prevalence cannot be ignored.

    With the increased interest in remote sensing of wind information in recent years, it is important to determine the reliability and accuracy of new wind measurement technologies if they are to replace or supplement conventional tower-based measurements. In view of this, HydroChina Corporation and the United States National Renewable Energy Laboratory (NREL) conducted a comparative test near a wind farm in Hebei Province, China. We present the results of an analysis characterizing the measurement performance of a state-of-the-art Sound Detection and Ranging (sodar) device when compared to a traditional tower measurement program. NREL performed the initial analysis of a three-month period and sent the results to HydroChina.

    INTRODUCTION The purpose of the U.S. Geological Survey?s (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The U.S. Geological Survey (USGS) recently completed an assessment of the undiscovered oil and gas potential of the Hanna, Laramie, and Shirley Basins Province in Wyoming and northeastern Colorado. The assessment is based on the geologic elements of each total petroleum system (TPS) defined in the province, including hydrocarbon source rocks (source-rock maturation, hydrocarbon generation, and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). Using this geologic framework, the USGS defined three TPSs and seven assessment units (AUs) within them; undiscovered resources for three of the seven AUs were quantitatively assessed.

    The People's Republic of China has undergone many changes over the past decade that have led to new growth and created opportunities for many industries, including the renewable energy industry. China has consistently had one of the fastest-growing economies in Asia. This report is a continuation of a market assessment done in 1997, which analyzed six provinces (Inner Mongolia, Gansu, Shandong, Qinghai, Xinjiang, and Zhejiang) in China. The information contained in this report comes mainly from interviews conducted with central and local government officials, state and local power bureau officials, and various company executives. The report provides valuable market information necessary for any company interested in entering China's renewable energy market. It also details the legal, competitive, sociocultural, technological, geographic, and economic environments of four provinces in China: Guangdong, Jiangxi, Jilin, and Yunnan. In addition, it outlines the major central government policies and contacts important to renewable energy development within China.

    Using a geology-based assessment methodology, the U.S. Geological Survey (USGS) estimated a mean undiscovered natural gas resource of 84,198 billion cubic feet and a mean undiscovered natural gas liquids resource of 3,379 million barrels in the Devonian Marcellus Shale within the Appalachian Basin Province. All this resource occurs in continuous accumulations. In 2011, the USGS completed an assessment of the undiscovered oil and gas potential of the Devonian Marcellus Shale within the Appalachian Basin Province of the eastern United States. The Appalachian Basin Province includes parts of Alabama, Georgia, Kentucky, Maryland, New York, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. The assessment of the Marcellus Shale is based on the geologic elements of this formation's total petroleum system (TPS) as recognized in the characteristics of the TPS as a petroleum source rock (source rock richness, thermal maturation, petroleum generation, and migration) as well as a reservoir rock (stratigraphic position and content and petrophysical properties). Together, these components confirm the Marcellus Shale as a continuous petroleum accumulation. Using the geologic framework, the USGS defined one TPS and three assessment units (AUs) within this TPS and quantitatively estimated the undiscovered oil and gas resources within the three AUs. For the purposes of this assessment, the Marcellus Shale is considered to be that Middle Devonian interval that consists primarily of shale and lesser amounts of bentonite, limestone, and siltstone occurring between the underlying Middle Devonian Onondaga Limestone (or its stratigraphic equivalents, the Needmore Shale and Huntersville Chert) and the overlying Middle Devonian Mahantango Formation (or its stratigraphic equivalents, the upper Millboro Shale and middle Hamilton Group).

    Introduction Matabeleland South launched the malaria pre-elimination campaign in 2012 but provincial spraying coverage has failed to attain 95% target, with some districts still encountering malaria outbreaks. A study was conducted to evaluate program performance against achieving malaria pre-elimination. Methods A descriptive cross sectional study was done in 5 districts carrying out IRS using the logical framework involving inputs, process, outputs and outcome evaluation. Health workers recruited into the study included direct program implementers, district and provincial program managers. An interviewer administered questionnaire, checklists, key informant interviewer guide and desk review of records were used to collect data. Results We enrolled 37 primary respondents and 5 key informants. Pre-elimination, Epidemic Preparedness and Response plans were absent in all districts. Shortages of inputs were reported by 97% of respondents, with districts receiving 80% of requested budget. Insecticides were procured centrally at national level. Spraying started late and districts failed to spray all targeted households by end of December. The province is using makeshift camps with inappropriate evaporation ponds where liquid DDT waste is not safely accounted for. The provincial IHRS coverage for 2011 was 84%. Challenges cited included; food shortages for spraymen, late delivery of inputs and poor state of IHRS equipment. Conclusion The province has failed to achieve Malaria pre-elimination IRS coverage targets for 2011/12 season. Financial and logistical challenges led to delays in supply of program inputs, recruitment and training of sprayers. The Province should establish camping infrastructure with standard evaporation ponds to minimise contamination of the environment. PMID:26015847

    To investigate contraceptive use among HIV-positive women in Ha long city and Cam Pha town of Quang Ninh, a Northern province of Vietnam. Cross-sectional questionnaire study among HIV-positive women identified through the district HIV/AIDS register. Information on socioeconomic characteristics and contraceptive use before and after HIV diagnosis was obtained through structured questionnaires. Chi-square testing was used to assess whether the included women differed from the target population in terms of age. Crude Odds ratios (ORs) were calculated to show the association between contraceptive use and the women's socioeconomic characteristics. Logistic regression analyses were applied to adjust for possible confounding. The women's contraceptive use before HIV testing and after HIV testing was described and compared by Chi-square testing, and the association between post-test counselling and the women's use of condom was assessed by ORs. Of the 351 participants, 63% stated they had used contraception before HIV diagnosis and 89% stated they had used contraception after HIV diagnosis. Forty six per cent of the women had been using either the pill or an intrauterine device (IUD) before the diagnosis whereas the same applied for only 8% of the women after diagnosis. Thirty-nine per cent stated they had been using condom before HIV diagnosis whereas 87% stated condom use after HIV diagnosis. Condom use was more common among women who had received post-test counselling (OR 3.03, 95% CI 1.03-8.90). A change of contraceptive methods from IUD and oral contraception before HIV diagnosis to condom use after HIV diagnosis was observed. The women's use of condoms after HIV diagnosis was associated with having received post-test counselling. © 2012 Blackwell Publishing Ltd.

    The tectonic style of Mars is dominated by vertical motion, perhaps more than any of the terrestrial planets. The imprint of this tectonic activity has left a surface widely faulted even though younger volcanism has masked the expression of tectonism in many places. Geological activity associated with the Tharsis and, to a lesser extent, Elysium provinces is responsible for a significant portion of this faulting, while the origins of the remaining features are enigmatic in many cases. The origin and evolution of the Tharsis and Elysium provinces, in terms of their great elevation, volcanic activity, and tectonic style, has sparked intense debate over the last fifteen years. Central to these discussions are the relative roles of structural uplift and volcanic construction in the creation of immense topographic relief. For example, it is argued that the presence of very old and cratered terrain high on the Tharsis rise, in the vicinity of Claritas Fossae, points to structural uplift of an ancient crust. Others have pointed out, however, that there is no reason that this terrain could not be of volcanic origin and thus part of the constructional mechanism.

    To assess the trends in the frequency and the medical effects of consanguinity in the south coast of Turkish population using local and national data in the last 11 years. This cross-sectional study was carried out in Manavgat province, which is a major tourism center on the Mediterranean coast of Turkey. The authors studied consanguineous marriages in rural and urban population in the Mediterranean coast, Manavgat province, Turkey, via a 1500 random survey sample of married couples. There has been a significant increase in the incidence of consanguineous marriages in rural areas (40.7%) since 1989 in the southern population of Turkey. The results showed that the most frequent type of marriage was between the first cousins. It is found that there is no statistically significant difference between the consanguineous and non-consanguineous marriages in the different age groups. The results were discussed on the basis of educational status, reasons for having consanguineous marriages and the general medical effects as well as with the relation of congenital malformations. The custom of consanguineous unions in the Mediterranean population of Turkey is still extremely high, and preventive measures should be done to decrease its frequency and associated complications.

    Shigella flexneri is one of the major etiologic causes of shigellosis in Guizhou Province, China. However, the genetic characteristics of circulating isolates are unknown. Phenotypic and molecular profiles of 60 S. flexneri isolates recovered in Guizhou between 1972 to 1982 and 2008 to 2010 were determined. Nine serotypes (1a, 2a, 3a, 1b, 2b, X, Y, 4av and Yv) were identified. Multi-locus sequence typing differentiated the isolates into 20 sequence types (STs); 18 were novel. Four STs, ST 129, ST 100, ST 126 and ST 18, were most abundant, accounting for 65% of the isolates. Thirty-nine NotI-pulsed field gel electrophoresis patterns (pulsotypes, PTs) were observed; eight PTs were represented by more than one isolate with six isolates sharing the PT 13 profile. Multi-locus variable-nucleotide tandem-repeat analysis recognized 44 different types (MTs); seven MTs were represented by more than one isolate and MT 1 was most commonly encountered. Correlation between genetic relationships and serotypes was observed among the isolates studied; the majority of isolates belonging to the same serotype from different years clustered together based on the molecular data. These clustered isolates were also from similar geographical origins. These results enhance our understanding of genetic relationships between S. flexneri in Guizhou Province and can be used to help understand the changing etiology of shigellosis in China.

    Using spatial analysis tools to determine the spatial patterns of China province-level perinatal mortality and using spatial econometric model to examine the impacts of health care resources and different socio-economic factors on perinatal mortality. The Global Moran's I index is used to examine whether the spatial autocorrelation exists in selected regions and Moran's I scatter plot to examine the spatial clustering among regions. Spatial econometric models are used to investigate the spatial relationships between perinatal mortality and contributing factors. The overall Moran's I index indicates that perinatal mortality displays positive spatial autocorrelation. Moran's I scatter plot analysis implies that there is a significant clustering of mortality in both high-rate regions and low-rate regions. The spatial econometric models analyses confirm the existence of a direct link between perinatal mortality and health care resources, socio-economic factors. Since a positive spatial autocorrelation has been detected in China province-level perinatal mortality, the upgrading of regional economic development and medical service level will affect the mortality not only in region itself but also its adjacent regions.

    BACKGROUND The alarming incidence of self- burning provoked to set up a multidisciplinary preventive program to decrease the incidence and complications of this harmful issue. This study investigated the incidence and the preventive measures in self-burn in Fars Province, southern Iran. METHODS This study was a longitudinal prospective design on trend of self-inflicted burn injuries in Fars province after setting up a regional multidisciplinary preventive plan (2009-2012). RESULTS From 18862 admitted patients, 388 (2%) committed self-burning. While the incidence showed a constant decrease in proportion of suicidal cases among all admitted patients (2.5% to 1.6%). The mean age of self-burning victims ranged from 28.3±10.8 to 30.3±11.7 years. The female victims comprised 67.4% of all suicidal burn patients (Female to male ratio: 2.18). The leading causes of suicide commitment were familial conflicts (75.6%) and psychological problems (16.7%) CONCLUSION It is crucial to continue the regional preventive programs and pave the way to set up national, and even international collaborations to alleviate relevant financial, social, cultural and infrastructural difficulties in order to have lower incidence for this dramatic issue.

    Mycobacterium tuberculosis (M. tuberculosis) genotyping has dramatically improved the understanding of the epidemiology of tuberculosis (TB). In this study, 187 M. tuberculosis isolates from Xinjiang Uygur Autonomous Region (Xinjiang) and Gansu province in China were genotyped using large sequence polymorphisms (LSPs) and variable number tandem repeats (VNTR). Ten isolates, which represent major nodes of VNTR-based minimum spanning tree, were selected and subsequently subjected to multi-locus sequence analyses (MLSA) that include 82 genes. Based on a robust lineage assignment, we tested the association between lineages and clinical characteristics by logistic regression. There are three major lineages of M. tuberculosis prevalent in Xinjiang, viz. the East Asian Lineage 2 (42.1%; 56/133), the Euro-American Lineage 4 (33.1%; 44/133), and the Indian and East African Lineage 3 (24.8%; 33/133); two lineages prevalent in Gansu province, which are the Lineage 2 (87%; 47/54) and the Lineage 4 (13%; 7/54). The topological structures of the MLSA-based phylogeny support the LSP-based identification of M. tuberculosis lineages. The statistical results suggest an association between the Lineage 2 and the hemoptysis/bloody sputum symptom, fever in Uygur patients. The pathogenicity of the Lineage 2 remains to be further investigated.

    The adsorption behaviors of Hg(II) on laterite from Guizhou Province, China, were studied and the adsorption mechanism was discussed. The results showed that different mineral compositons in the laterite will cause differences in the adsorption capacity of laterite to Hg(II). Illite and non-crystalloids are the main contributors to enhancing the adsorption capacity of laterite to Hg(II). The pH of the solution is an important factor affecting the adsorption of Hg(II) on laterite. The alkalescent environment (pH 7-9) is favorable to the adsorption of Hg(II). The amount of adsorbed Hg(II) increases with increasing pH. When the pH reaches a certain value, the amount of the adsorbed Hg(II) will reach the maximum level. The amount of adsorbed Hg(II) decreases with increasing pH. The optimal pHs of laterite and kaolinite are 9 and 8, respectively. The optimal initial concentrations of Hg(II) on laterite and kaolinite are 250 and 200 microg/ml, respectively. The adsorption isotherms were described by the Langmuir model. The adsorption of Hg(II) on laterite is a quick process while that of Hg(II) on kaolinite is a slow reaction. Laterite from Guizhou Province is a promising environmental material which can be used in the removal of Hg(II) from wastewater.

    The Rungwe Volcanic Province in SW Tanzania is a densely populated area that is considered volcanically active. As part of the East African Rift System, a significant control of tectonic activity seems to exist on the location and also potential destabilization of volcanic edifices. Three large volcanoes, Ngozi, Rungwe, and Kyejo, dominate the landscape and all show contrasting eruptive behaviour in the recent geological past. Kyejo volcano is a flow-dominated volcano that had a historic lava flow eruption. Lake sediment cores, drilled in Lakes Malawi, Masoko, Rukwa, and Tanganyika, provide a record of frequent explosive eruptions in the last few tens of thousands of years. In combination with on-land stratigraphic observations, they constrain the minimum eruptive frequency of especially Rungwe and Ngozi volcanoes. Both volcanoes had Plinian-style eruptions in the Holocene. The most striking documented Rungwe eruption, the ca. 4 ka Rungwe Pumice, is a rare case of a Plinian eruption in near-wind-free conditions. Furthermore, the Rungwe Pumice, just like any other Rungwe tephra deposit, does not show any evidence of pyroclastic density current deposits. Apart from explosive eruptions at a range of scales happening every few hundred years at Rungwe, the volcano also experienced at least two sector collapse events generating debris avalanches. All existing evidence shows that the Rungwe Volcanic Province is prone to future significant explosive eruptions. To further assess, quantify and mitigate volcanic hazard risks, extensive and systematic multidisciplinary geological research, and both volcanic and tectonic monitoring are needed.

    Background: The prevalence and etiology of infertility are not similar in different parts of the world. There are only few reports of this topic in Iran. Objective: This study was conducted to determine the clinical patterns and major causes of infertility in Mazandaran province in north of Iran. Materials and Methods: The medical records of 3734 consecutive couples attending two infertility clinics in Mazandaran province, from 2003 to 2008, were reviewed. The couples had not had a viable birth after at least 1 year of unprotected intercourse and were fully investigated. Results: Of the entire samples, 78.7% had primary infertility and 21.3% had secondary infertility. The mean duration of infertility in couples was 5.7±4 years. The etiology of infertility in couples revealed; male factor in 38.9%, female factor in 34.7%, combined factors in 14.6% and undetermined cause in 11.8%. Conclusion: In this study, delayed attendance of infertile couples to the infertility clinic was found. Therefore, there is a need to revise public health program on infertility to focus on the education and prevention of infertility and its risk factors. PMID:25356077

    To summarize the changing epidemiological characteristics of malaria in Zhejiang Province, China, we collected data on malaria from the Chinese Notifiable Disease Reporting System (NDRS) and analyzed them. A total of 2,738 malaria cases were identified in Zhejiang Province from 2005 to 2014, of which 2,018 were male and 720 were female. Notably, only 7% of malaria cases were indigenous and the other cases were all imported. The number of malaria cases increased from 2005 to 2007, peaked in 2007, and then decreased from 2007 to 2011. There were no indigenous cases from 2012 to 2014. Of all cases, 68% of cases contracted Plasmodium vivax, 27% of cases contracted P. falciparum, and two cases contracted P. malariae. About 88% of malaria cases during 2005–2011 occurred yearly between May and October, but the number of malaria cases in different months during 2012–2014 was similar. The median age was 33 years, and 1,892 cases occurred in persons aged 20–50 years. The proportion of businessmen increased and the proportion of migrant laborers decreased in recent years. The median time from illness onset to confirmation of malaria cases was 5 days and it decreased from 2005 to 2014. Some epidemiological characteristics of malaria have changed, and businessmen are the emphases to surveillance in every month. PMID:26078321

    The existence of gaps that occur between regions, shows that it is a reasonable process considering that each region has different initial endowment factors. The first step that can be done to controll disparity is know what is the benchmark of the gap. The revenue growth indicator is one of benchmark for measuring regional disparities. The regional output is represented by the gross domestic regional income per capita. Concerning the phenomenon of regional disparity, East Java Province is concentrated in the north-south part, especially in coastal areas is an early indication of the gap. This is what prompted the analysis of predictor factors affecting the disparity in East Java Coastal Areas through a spatial modeling approach. Spatial modeling is done on the consideration that there are different local characteristics or potentials in each regency / city. Factors Economic growth, social factors, and physical development factors are the main factors in this study will be described in derived variables to obtain a clear picture of the influence of each factor to the disparity that occurred in the Coastal Region of East Java Province.

    A liver fluke, Opisthorchis viverrrini (OV), is the major cause of the high incidence of cholangiocarcinoma in Thailand. The prevalence of OV infection remains high in various parts of the country, especially in Northeast Thailand and particularly in wetland rural areas where a large proportion of the community work in agriculture and continue the traditional practice of eating raw or undercooked cyprinoid fish products. The national control program seems to have had little impact in many of these areas, and it has been difficult to make precise assessments of the overall effectiveness of the program. This paper is the first report of prospective research project designed to monitor the impact of the national control program in rural communities located in a northeastern province and at high risk of OV infection. The participants in this initial survey were 1,569 villagers, aged 20-65 years, living in two subdistricts of Yasothon Province. Stool examinations showed that 38.68% were infected with OV. Males were slightly more likely to be infected than females, but the difference was not statistically significant. Infection was found to be positively associated with age in both males and females. The preliminary data indicate that the population selected for study is suitable for the purpose of the monitoring project.

    It is important to quantitatively assess the climate suitability of tea and its response to climate change. Based on meteorological indices of tea growth and daily meteorological data from 1971 to 2010 in Zhejiang Province, three climate suitability models for single climate factors, including temperature, precipitation and sunshine, were established at a 10-day scale by using the fuzzy mathematics method, and a comprehensive climate suitability model was established with the geometric average method. The results indicated that the climate suitability was high in the tea growth season in Zhejiang Province, and the three kinds of climate suitability were all higher than 0.6. As for the single factor climate suitability, temperature suitability was the highest and sunshine suitability was the lowest. There were obvious inter-annual variations of tea climate suitability, with a decline trend in the 1970s, less variation in the 1980s, and an obvious incline trend after the 1990s. The change tendency of climate suitability for spring tea was similar with that of annual climate suitability, lower in the 1980s, higher in the 1970s and after the 1990s. However, the variation amplitude of the climate suitability for spring tea was larger. The climate suitability for summer tea and autumn tea showed a decline trend from 1971 to 2010.

    Employing real-site investigation and data analysis methods, this paper analyzed the distribution of plantation stocks and its affecting factors in western Liaoning Province. The results showed that the average plantation stock of western Liaoning was 49.08 m3.hm(-2), which has been improved obviously since 1949. At the time of the third forest resource investigation, the plantation stock increased 20.19 m3.hm(-2), 5.16 times higher than that of the first forest resource investigation. But, the general plantation stock of western Liaoning was still at a rather lower level, with only a 63.5% increase of the whole province and 51.1% of the national average plantation stock at the same period. The difference of plantation stock among cities in western Liaoning was observable, that even reached 68.47 m3.hm(-2). In general, the proportion of young forest was too high, reached to 49 % of the total plantation, while the stock of mature forest was much lower, only 38% of the national average level. The plantation stock of national property was only 55.1% and 32.3% of the personal and collective property, respectively. Moreover, the plantation stock of timber forest was 36.4% lower than that of windbreak. Besides climatic factors, simple plantation structure, few forest tree species, and poor plantation management were the main causes of the low plantation stock.

    Rice is a staple food in China, but it may contain toxic heavy metals. Hence, the concentrations of arsenic (As) species (As(III), As(V), MMA and DMA) were evaluated in 260 rice samples from 13 cities of Guangdong Province, the most economically dynamic provinces of China. The levels of sum concentrations of As species in rice samples varied from non-detect to 225.58 ng g(-1), with an average value of 57.27 ng g(-1). The mean concentrations of the major As species detected in rice samples were in the order As(III) (34.77 ng g(-1)) > As(V) (9.34 ng g(-1)) > DMA (8.33 ng g(-1)) > MMA (4.82 ng g(-1)). The rice samples of Guangdong Province were categorized as inorganic As type. Significant geographical variation of As speciation existed in rice samples of 13 cities of Guangdong Province by chi-square test (p < 0.05). The average human weekly intakes of inorganic As via rice consumption in Guangdong Province, southern China, were 1.91 µg kg(-1) body weight. Hazard quotients of total As via rice consumption of adults in 13 cities ranged from 0.06 to 0.30, indicating the As contents in rice from Guangdong Province had no potential adverse impact on human health.

    Forests play an irreplaceable role in maintaining regional ecological environment, global carbon balance and mitigating global climate change. Forest aboveground biomass (AGB) is an important indicator of forest carbon stocks. Estimating forest aboveground biomass accurately could significantly reduce the uncertainties in terrestrial ecosystem carbon cycle. LIDAR provides accurate information on the vertical structure of forests (Lefsky et al., 2007; Naesset et al., 2004; Pang et al., 2008). Combining airborne LiDAR and spaceborne LiDAR for regional forest biomass retrieval could provide a more reliable and accurate quantitative information in regional forest biomass estimate (Boudreau et al., 2008; Nelson et al., 2009; Pang et al., 2011; Saatchi et al., 2011). The Heilongjiang Province and Yunnan Province are rich in forest resources and suffers intensive forest management activities for timber products. The Heilongjiang Province is typical in temperate forest and the Yunnan Province contains multiple forest types including tropical forest. These two provinces also have good ground inventory system with thousands of permanent field plots. Two campaign consists of in-situ measurement, airborne Lidar data and spaceborne data fusion were designed and implemented. First results show that i). Both spaceborne lidar and forest inventory data are useful for AGB mapping at province level. ii). The combination of spaceborne lidar and forest inventory data gave better biomass estimation with less bias. iii). A pixel level bias mapping was also proposed and gave spatial explicit map of estimation uncertainties. This method will be investigated further with more reference data and tested in other area.

  10. Irrigation Management Transfer and WUAs' dynamics: evidence from the South-Kazakhstan province

    The importance of water resources management in the arid and semi-arid lands can not be overestimated being related with environmental, economical and socio-political issues. In Central Asia, due to the physical and climatic features, water control and irrigation have always played a strategic role in territorial and societal development. Since the collapse of the Soviet Union in Kazakhstan, as in the other Central Asian republics, significant changes in both the water and agricultural sector have emerged; water management shifted from a purely technical issue to a sociopolitical and economic one leading to several institutional and organizational changes. To address this transitional water management context and the related governance and technical issues, since the 1990s several development organizations and donor agencies (such as the World Bank, United Nations, USAID, and others), according to the international water community, have sought to streamline the Irrigation Management Transfer (IMT) and the establishment of the Water Users Associations (WUAs); this initiatives are sponsored and related to the IWRM framework, the water program globally supported by the Global Water Partnership and widely debated and questioned in the last years. This paper aims to discuss these transitional water management processes focusing on the meso-local level in the Arys valley, administratively included in the South-Kazakhstan province, ten years since the enactment of the law formalizing the WUAs. Three districts (Tyulkibas, Ordabasy and Otrar) were selected to analyse and understand the specific local transitional water institutional/organizational framework and to highlight the differences among them. The fieldwork was conducted in two different phases, April-May and November-December 2012. Within those periods, semi-structured interviews were carried out to the members of the state organizations (river basin agencies and district/province water departments) as well as the

    The author has identified the following significant results. Field reconnaissance and study of geologic literature guided by analysis of ERTS-1 MSS imagery have led to a hypothesis of tectonic control of Miocene volcanism, plutonism, and related mineralization in part of the Basin Range Province of southern Nevada and northwestern Arizona. The easterly trending right-lateral Las Vegas Shear Zone separates two volcanic provinces believed to represent areas of major east-west crustal extension. One volcanic province is aligned along the Colorado River south of the eastern termination of the Las Vegas Shear Zone; the second province is located north of the western termination of the shear zone in southern Nye County, Nevada. Geochronologic, geophysical, and structural evidence suggests that the Las Vegas Shear Zone may have formed in response to crustal extension in the two volcanic provinces in a manner similar to the formation of a ridge-ridge transform fault, as recognized in ocean floor tectonics.

  12. Large igneous provinces generated from the margins of the large low-velocity provinces in the deep mantle

    There is a clear correlation between downward projected large igneous province (LIP) eruption sites of the past 200 Myr and the margins of the large low-velocity provinces (LLVPs) at the base of the mantle. We established this correlation by using palaeomagnetic as well as fixed and moving hotspot reference frames. Our finding indicates that the majority of the LIPs have been generated by plumes that rose from the D'' zone at the edges of the LLVPs. Most LIP eruption sites project radially downwards to the core-mantle boundary (CMB) within +/-10° of the 1 per cent slow shear wave velocity contour in the SMEAN tomographic model. Steep shear wave velocity gradients have been mapped near the CMB along much of the lengths of the LLVP margins close to that contour which marks a faster/slower boundary (FSB) within the D'' zone. The observation that eruption sites of LIPs as old as 200 Myr can be linked to this prominent present day seismic structure shows that the FSBs of the two LLVPs have occupied their current positions for at least as long and that the process that leads to the generation of deep-seated plumes has been localized on the FSBs at the margins of the African and Pacific LLVPs for the same interval. The persistence of the LLVPs over 200 Myr is consistent with independent evidence that they are compositionally distinct and are not just simply hotter than the material making up the rest of the D'' zone.

    Abstract Influenza as a severe infectious disease has caused catastrophes throughout human history, and every pandemic of influenza has produced a great social burden. We compiled monthly data of influenza incidence from all provinces and autonomous regions in mainland China from January 2004 to December 2011, comprehensively evaluated and classified these data, and then randomly selected 4 provinces with higher incidence (Hebei, Gansu, Guizhou, and Hunan), 2 provinces with median incidence (Tianjin and Henan), 1 province with lower incidence (Shandong), using time series analysis to construct an ARIMA model, which is based on the monthly incidence from 2004 to 2011 as the training set. We exerted the X-12-ARIMA procedure for modeling due to the seasonality these data implied. Autocorrelation function (ACF), partial autocorrelation function (PACF), and automatic model selection were to determine the order of the model parameters. The optimal model was decided by a nonseasonal and seasonal moving average test. Finally, we applied this model to predict the monthly incidence of influenza in 2012 as the test set, and the simulated incidence was compared with the observed incidence to evaluate the model's validity by the criterion of both percentage variability in regression analyses (R2) and root mean square error (RMSE). It is conceivable that SARIMA (0,1,1)(0,1,1)12 could simultaneously forecast the influenza incidence of the Hebei Province, Guizhou Province, Henan Province, and Shandong Province; SARIMA (1,0,0)(0,1,1)12 could forecast the influenza incidence in Gansu Province; SARIMA (3,1,1)(0,1,1)12 could forecast the influenza incidence in Tianjin City; and SARIMA (0,1,1)(0,0,1)12 could forecast the influenza incidence in Hunan Province. Time series analysis is a good tool for prediction of disease incidence. PMID:27367989

    To describe dietary sodium intakes and resources among residents in Shandong province. A total of 2184 subjects were selected by multi-stage stratified cluster random sampling method from 18-69 years old people in Shandong province in June, 2011. A total of 2140 subjects completed the study, the completion rate was 98.0%. Three-day (24-hour per day) dietary recalls and weighting methods were conducted to collect information about all the foods and condiments consumed by the subjects. Individual dietary sodium intake was calculated, the differences of dietary sodium intake among subjects with different characteristics were analyzed, and the proportions of different dietary sodium resources were also analyzed. The amount of individual dietary sodium intake was 5745.0 (95%CI:5427.6-6062.5) mg/d in Shandong; 6147.4 (95%CI: 5823.8-6471.0) mg/d for male residents, 5339.3 (95%CI:5005.8-5672.8) mg/d for female residents. There was a significant difference between males and females (F = 75.22, P < 0.01). The amount of individual dietary sodium intake was 5910.1 (95%CI:5449.3-6370.8) mg/d, 5341.6 (95%CI:5007.0-5676.1) mg/d for rural residents and urban residents respectively, and there was also a significant difference (F = 5.53, P < 0.05). The amount of condiment sodium intake was 4640.3 (95%CI:4360.2-4920.4) mg/d, which was the largest contributor to sodium intake, accounting for 80.8% (95%CI:79.9%-81.6%) of total intake. Sodium intake from cereals was 650.7 (95%CI: 590.5-711.0) mg/d, accounting for 11.3% (95%CI:10.3%-12.3%) of total intake. Sodium intake from eggs was 118.9 (95%CI:95.2-142.6) mg/d, accounting for 2.1% (95%CI:1.6%-2.6%) of total intake.

    1996-01-01

    Lunar sample 15474,4 is a tiny fragment of olivine-augite vitrophyre that is a mare basalt. Although petroraphically distinct from all other Apollo 15 samples, it has been ignored since its first brief description. Our new petrographic and mineral chemical data show that the olivines and pyroxenes are distinct from those in other basalts. The basalt cooled and solidified extremely rapidly; some of the olivine might be cumulate or crystallized prior to extrusion. Bulk-chemical data show that the sample is probably similar to an evolved Apollo 15 olivine-normative basalt in major elements but is distinct in its rare earth element pattern. Its chemical composition and petrography both show that 15474,4 cannot be derived from other Apollo 15 mare basalts by shallow-level crystal fractionation. It represents a distinct extrusion of magma. Nonetheless, the chemical features that 15474,4 has in common with other Apollo 15 mare basalts, including the high FeO/Sc, the general similarity of the rare earth element pattern, and the common (and chondritic) TiO2/Sm ratio, emphasize the concept of a geochemical province at the Apollo 15 site that is distinct from basalts and provinces elsewhere. In making a consistent picture for the derivation of all of the Apollo 15 basalts, both the commonalities and the differences among the basalts must be explained. The Apollo 15 commonalities and differences suggest that the sources must have consisted of major silicate phases with the same composition but with varied amounts of a magma trapped from a contemporary magma ocean. They probably had a high olivine/pyroxene ratio and underwent small and reasonably consistent degrees of partial melting to produce the basalts. These inferences may be inconsistent with models that suggest greatly different depths of melting among basalts, primitive sources for the green glasses, or extensive olivine fractionation during ascent. An integrated approach to lunar mare provinces, of which the Apollo 15

    There has been increasing effort in recent years to employ satellite remotely sensed data to identify and map vector habitat and malaria transmission risk in data sparse environments. In the current investigation, available satellite and other land surface climatology data products are employed in short-term forecasting of infection rates in the Mpumalanga Province of South Africa, using a multivariate autoregressive approach. The climatology variables include precipitation, air temperature and other land surface states computed by the Off-line Land-Surface Global Assimilation System (OLGA) including soil moisture and surface evaporation. Satellite data products include the Normalized Difference Vegetation Index (NDVI) and other forcing data used in the Goddard Earth Observing System (GEOS-1) model. Predictions are compared to long- term monthly records of clinical and microscopic diagnoses. The approach addresses the high degree of short-term autocorrelation in the disease and weather time series. The resulting model is able to predict 11 of the 13 months that were classified as high risk during the validation period, indicating the utility of applying antecedent climatic variables to the prediction of malaria incidence for the Mpumalanga Province.

    By building urbanization and eco-environment evaluation index systems, the levels of urbanization and eco-environment, and the degree of their coupling coordination of Jilin Province from 2000 to 2012 were evaluated. The level of comprehensive urbanization showed a continued growth trend, and the economic urbanization contributed the largest share. The eco-environment comprehensive level fluctuated upward. The eco-environment state, response and pressure increased faster since the implementation of the strategy of revitalizing Northeast China and other old industrial regions. Coupling coordination degree between urbanization and eco-environment increased continuously, from uncoordinated status to advanced coordinated status, changing from eco-environment lagged to urbanization lagged. The level of urbanization in central region was higher than east and west regions in Jilin Province, but its eco-environment level was low. Coupling coordination degree in Changchun was the highest, and that of Baishan was the lowest. Coupling coordination degree of Chang-Ji integrated region was always at the leading level, but the level of eco-environment lagged behind was growing since 2000. Coupling coordination degree of Siping, Liaoyuan, Songyuan and Yanbian increased, but that of Baicheng decreased.

    This study presents the seasonal variations of indoor radon levels in dwellings located in the Ramallah province and East Jerusalem suburbs, Palestine. The measurements were performed during the summer and winter of the year 2006/2007 using CR-39 solid-state-nuclear-track detectors. The total number of investigated buildings is 75 in summer and 81 in winter. A total number of 142 dosemeters are installed in dwellings for each season for a period of almost 100 d. The radon concentration levels in summer varied from 43 to 192 Bq m(-3) for buildings in the Ramallah province and from 30 to 655 Bq m(-3) for East Jerusalem suburbs. In winter, the radon concentration levels are found to vary from 38 to 375 Bq m(-3) in the Ramallah buildings and from 35 to 984 Bq m(-3) in East Jerusalem suburbs. The obtained results for radon concentration levels in most places are found to be within the accepted international levels.

    Emissions of gaseous and particulate pollutants from burning of wheat straw, rice straw, cotton straw, and bagasse were studied for the two agricultural-activity-dominated provinces of Pakistan: the Punjab and Sindh. Emission estimates, inventory, and allocation maps indicated distinct patterns of pollutant emissions in the two provinces. Comparative pollutant emission analysis revealed that the Punjab province produced higher pollutants from agricultural biomass burning than Sindh province. Total emissions from these two provinces were estimated to be 16,084.04 Gg (16.08 Tg) for the year 2006/2007. Wheat straw was found to be the dominant source of CO, CO2, SO2, NOx, and EC emissions in the both provinces. However, for the emissions of CH4, NH3, EC, and OC, the Punjab and Sindh provinces differed markedly for the crop residue share in these pollutant emissions. Rice straw was found to be the largest contributor of CH4 (51%) and NH3 (65%) in Sindh province. When total emissions from biomass burning were considered at provincial level, wheat straw and bagasse were the major crop residues which accounted for 72 and 14% of pollutant emissions, respectively, in the Punjab province, whereas, in Sindh province, the order of crop residue contribution in total emission was as follows: wheat (59%) > bagasse (19%) > rice (14%) > cotton (7%). Emission inventory data of total pollutants per unit area under cultivation (Mg ha(-1)) revealed that Sindh province produced higher emissions per hectare for wheat straw, rice straw, and bagasse than the Punjab province.

    A compilation of groundwater-quality data collected as part of two U.S. Geological Survey studies provides a basis for understanding the ambient geochemistry related to geologic setting in the Piedmont and Blue Ridge Physiographic Provinces (hereafter referred to as Piedmont and Mountains Provinces) of North Carolina. Although the geology is complex, a grouping of the sampled wells into assemblages of geologic units described as 'geozones' provides a basis for comparison across the region. Analyses of these two data sets provide a description of water-quality conditions in bedrock aquifers of the Piedmont and Mountains Provinces of North Carolina. Analyzed data were collected between 1997 and 2008 from a network of 79 wells representing 8 regional geozones distributed throughout the Piedmont and Mountains Provinces. This area has experienced high rates of population growth and an increased demand for water resources. Groundwater was used by about 34 percent of the population in the 65 counties of this region in 2005. An improved understanding of the quality and quantity of available groundwater resources is needed to plan effectively for future growth and development. The use of regional geologic setting to characterize groundwater-quality conditions in the Piedmont and Mountains Provinces is the focus of this investigation. Data evaluation included an examination of selected properties and the ionic composition of groundwater in the geozones. No major differences in overall ionic chemistry of groundwater among the geozones were evident with the data examined. Variability in the cationic and anionic composition of groundwater within a particular geozone appeared to reflect local differences in lithologic setting, hydrologic and geochemical conditions, and(or) land-use effects. The most common exceedances of the drinking-water criteria (in accordance with Federal and State water-quality standards) occurred for radon, pH, manganese, iron, and zinc. Radon had the most

    The Direct/Delayed Response Project (DDRP) is one of several studies being conducted by the United States Environmental Protection Agency to assess risk to surface waters from acidic deposition in the eastern United States. In one phase of DDRP, land use, wetland, and forest cover data were collected for statistical samples of 145 Northeast lake and 35 Southern Blue Ridge Province stream watersheds in the United States. Land-use and other data then were extrapolated from individual to target watershed populations. Project statistical design allows summarization of results for various subsets of the target population. This article discusses results and implications of the land-use and land-cover characterization for both regions. Forest cover was the primary land use in both regions. In the Northeast, developed (agriculture and urban) land was positively associated with surface-water chemistry values for acid neutralizing capacity, Ca plus Mg, pH, and sulfate in the Pocono/Catskill subregion. Extensive wetlands and beaver activity occur in parts of the Northeast region, whereas topography limits wetland and riparian development in the Southern Blue Ridge Province. Northeast soils have low sulfate adsorption capacity, most watersheds are near sulfur steady state, and lake sulfate concentrations are controlled principally by levels of sulfur deposition. Net annual sulfur retention in Northeast watersheds is positively correlated with occurrence of wetlands and beaver impoundments. In contrast, most Southern Blue Ridge Province soils have high sulfate adsorption capacities, resulting in high net watershed sulfur retention. At the present time, stream sulfate concentrations and percent sulfur retention are controlled principally by soil chemical properties related to adsorption rather than atmospheric deposition and land use.

  4. Basalt geochemistry and tectonic discrimination within continental flood basalt provinces

    1987-06-01

    Continental flood basalts are usually regarded as a single tectonomagmatic entity but frequently quoted examples exhibit a variety of tectonic settings. In one well-studied, classic, flood basalt province, the Mesozoic Karoo province of southern Africa, magmatism occurred in the following tectonic settings: (a) continental rifting leading to ocean-floor spreading in the South Atlantic Ocean (Etendeka suite of Namibia); (b) stretched continental lithosphere and rifting not leading directly to ocean-floor formation (Lebombo suite of southeastern Africa); and (c) an a-tectonic, within-plate, continental setting characterized by an absence of faulting or warping (Lesotho highlands and Karoo dolerites of South Africa). By means of spidergrams of the elements Rb, Ba, Th, Nb, K, La, Ce, Sr, Nd, P, Hf, Zr, Sm, Ti, Tb, Y, V, Ni and Cr, uncontaminated tholeiites from (c) above [i.e. the Lesotho-type continental flood basalts (LTCFB)] are compared with mid-ocean ridge basalts (MORB), ocean-island tholeiites (OIT), and tholeiites and calc-alkali basalts from subduction environments. The comparison reveals the LTCFBs are geochemically distinct. The differences are reflected in relative enrichments or depletions of the more incompatible elements (Rb-Ce) to less incompatible elements (Ce-Y), i.e. the overall slope of the spidergrams, and in anomalous enrichments or depletions of one or more of the elements Th, K, Nb, Sr, Ti, Hf, and Zr. The distinctive geochemical character of the Lesotho LTCFBs is interpreted in terms of a lithospheric mantle source for the basalts. This is supported by isotopic data. There are no major geochemical differences between Lesotho CFBs and basalts of the rift-related Etendeka and Lebombo suites, although the latter are somewhat enriched in Rb, Ba and K. However, unlike the Lesotho basalts, the Lebombo and Etendeka basalts are associated with voluminous silicic volcanics or intrusive centres and late-stage dolerites having MORB/OIT (i

    Superior Province consists mainly of Late Archean rocks with Middle Archean gneisses in the south, and possibly in the north. The Late Archean supracrustal sequences are of island arc and interarc affinity and are cut by abundant plutonic rocks, including early arc-related intrusions, late synorogenic intrusions, and post-orogenic plutons that are possibly the product of crustal melting caused by thermal blanketing of newly-thickened continental crust combined with high mantle heat flux. The contemporaneity of magmatic and deformational events along the lengths of the belts is consistent with a subduction-dominated tectonic regime for assembly of the Kenoran Orogen. Successive addition of volcanic arcs accompanied and followed by voluminous plutonism resulted in crustal thickening and stabilization of the Superior craton prior to uplift of Kapuskasing granulites, emplacement of the Matachewan diabase dykes, and Early Proterozoic marginal rifting.

    A survey of ectoparasites on rodents was carried out bimonthly from April 2008 to March 2009 in 3 districts of Sukhothai Province, northern Thailand. A total of 130 rodents comprising 8 species of hosts were captured and examined for ectoparasites. The hosts examined were Bandicota indica, Bandicota savilei, Rattus losea, Rattus rattus, Rattus exulans, Rattus norvegicus, Menetes berdmorei and Tamiops mcclellandii. Ninety-seven ectoparasites were collected: 1 species of tick (Hemaphysalis bandicota), 2 species of mites (Laelaps nuttali and Laelaps echidninus), and 1 species of flea (Xenopsylla cheopis) were identified. The infestation rates by ticks, mites and fleas on the rodents were 0.77, 5.38 and 6.15%, respectively. Monitoring the rodent population and their ectoparasites is important for future planning of prevention and control of zoonotic diseases in the area.

    The aim of this study is to identify the most important characteristics of fresh pork that determine consumer choice in five Canadian provinces. Within-consumer preference replication and systematic image manipulation in surveying showed differences in strategies for pork choice in lean colour (P<0.001) and marbling (P=0.006). High proportions of Nova Scotians (29%) chose light red pork, Albertans (42%) dark red and Quebecers (29%) non-marbled pork. Overall, the most important choice criteria were fat cover (57% preferred lean, 8% fatty) and lean colour (35% dark red, 18% light red). Marbling and drip were less used, but are important noting that 26% of consumers used three or four characteristics to make their choice. The preferences are readily met by the industry, but unfortunately, preferences for minimal or no marbling and fat cover likely result in a compromised gustative experience for many Canadian consumers.

    Fifty-one specimens of small mammals were collected from different locations of Kerman province, southeastern Iran during 2007 and 2009. They constitute six species of rodents (Meriones persicus, Meriones libycus, Tatera indica, Dryomys nitedula and Mus musculus), one species of Erinaceomorpha (Paraechinus hypomelas) and one species of hare (Lepus europeus). The rate of helminthic infection was 45.1 % among all trapped specimens. In 28 out of 51 hunted specimens no intestinal helminth parasite was found. Of all mammals examined, 15 (29.4 %) had nematodes, 5 (9.8 %) had cestodes, and 3 (5.9 %) were infected with Acanthocephala. Five different species of parasites were isolated: Trichuris muris, Moniliformis moniliformis, Hymenolepis diminuta, Hymenolepis nana, and Mastophorus muris. Results of the present study indicate the potential of small mammals in the transmission of zoonotic helminthic infection.

    The eastern region of the Interior Coal Province has been divided into 11 hydrologic study areas. Area 25, located in west-central Illinois, includes the Spoon River and small tributaries to the Illinois River. Pennsylvanian age rocks underlie most of the study area. Illinois, with the largest reserves of bituminous coal, is second only to Montana in total coal reserves. Loess soils cover most of the study area. Agriculture is the dominant land use. Surface water provides 97% of all the water used. Precipitation averages 34 to 35 inches. Water-quality data has been collected at over 31 sites. Analysis for specific conductance, pH, alkalinity, iron, manganese, sulfate and many trace elements and other water-quality constituents have been completed. These data are available from computer storage through the National Water Data Storage and Retrieval System (WATSTORE). (USGS)

    This paper examines patterns of remittances among migrants from Guizhou province of China. Our research is motivated by three lines of theoretical arguments, namely the new economics of migration, a translocal perspective linking remittances and development, and the culture of remittances. Taking individual, household, and village-level characteristics into account, we estimated multilevel logistic models of the decision to remit and multilevel models of the amount of remittances. Our results show that migrant remittance behaviour is responsive to family needs as well as household economic position in the village.. Migrants who come from entrepreneurial households are more likely to remit a large amount than other types of households. We find some evidence of “culture of remittances” in these villages. Consistent with our expectations, migrants who are from villages with higher amount of average remittances are likely to remit a larger amount than otherwise. PMID:26146509

    In order to determine the geothermal resource potential of Niǧde, Nevşehir and Aksaray provinces in Central Anatolian Volcanic Province (CAVP), geothermal fluids, surface water, and alteration rock samples from the Cappadocia volcanic zone in Turkey were investigated for their geochemical and stable isotopic characteristics in light of published geological and tectonic studies. Accordingly, the Cappadocia Geothermal Province (CGP) has two different geothermal systems located along tectonic zones including five active and two potential geothermal fields, which are located between Tuzgölü Fault Zone and Keçiboyduran-Melendiz Fault and north of Keçiboyduran-Melendiz Fault. Based on water chemistry and isotope compositions, samples from the first area are characterized by Ca-Mg-HCO3 ve Ca-HCO3 type mineral poor waters and Ca-Na-SO4 and Ca-Mg-SO4 type for the cold waters and the hot waters, respectively, whereas hot waters from the second area are Na-Cl-HCO3 and Ca-Na-HCO3 type mineral poor waters. According to δ18O and δ2H isotope studies, the geothermal waters are fed from meteoric waters. Results of silica geothermometer indicate that the reservoir temperature of Dertalan, Melendiz Mount, Keçiboyduran Mount, Hasan Mount (Keçikalesi), Ziga, Acıgöl, and Derinkuyu geothermal waters are 150-173 oC, 88-117 oC, 91-120 oC, 94-122 oC, 131-156 oC, 157-179 oC; 152-174 oC and 102-130 oC, respectively. The REE composition of geothermal fluids, surface water, and mineral precipitates indicate that temperature has a strong effect on REE fractionation of the sampled fluids. Eu- and Ce- anomalies (Eu/Eu*, Ce/Ce*) are visible in several samples, which are related to the inheritance from the host reservoir rocks and redox-controlled fractionation of these elements during water-rock interactions. REE and Yttrium geochemistry results of altered rock samples and water samples, which were taken from same locations exhibited quite similar features in each system. Hence, it was

    The relationship between immigration and crime is politically charged and often fueled by the presence (or lack) of xenophobia. Many theoretical and empirical assessments of this relationship indicate that immigration does indeed lead to increased crime, but more recent (and very early) research investigating homicide calls this finding into question. The current analysis investigates the relationship between immigration and homicide using multiple measures of migration and Canadian provinces as the unit of analysis. It is found that the link between immigration and homicide is complex and dependent on the measure of migration used. Generally speaking, the results presented here are consistent with the more recent and very early research. Immigration, in and of itself, does not increase homicide. Rather it is the increase in the most criminogenic subpopulation that matters, that is young males.

    Puerh tea, as the most representative Chinese dark tea, has attracted global interest in recent years. Profiling the levels of metal elements in Puerh tea is very important since its presence is related to human health. In this study, 41 elements in 98 Puerh tea samples from Yunnan province, China including Puerh raw tea and Puerh ripe tea were evaluated by microwave digestion combined with inductively coupled plasma mass spectrometry . The content of toxic elements, essential elements and rare earth elements of Puerh tea from different regions was discussed in detail. The concentrations of Ba, Cr, As, Pb, Bi, Fe, Zn, V, Mn, Be, Ag and Tl showed significant differences (p < 0.05) by ANOVA analysis. Principal component analysis and linear discriminant analysis were used to describe the relationship of Puerh tea from different regions. This study provided a comprehensive database for Puerh tea quality control and intake risk assessment.

    This paper shows how disease transmission and particularly what biomedicine calls tuberculosis are interpreted in the non-Western context of Aceh Province, Sumatra, Indonesia. It tries also to focus on factors influencing perceptions and health-seeking behaviors. Results show that what biomedicine calls TB is represented by a semantic network of illnesses. Parts of this network are clearly identified as transmissible while others are related to specific phenomena affecting the individual, such as terbuk (poisoning) or trouk (fatigue produced by hard work), and are not considered contagious. Forms of transmission are interpreted mostly through empirical and analogic categories. TB is attributed to four different aspects: (a) biomedical categories such as germ theory; (b) socio-economic conditions; (c) transgression of social rules; and (d) poisoning and the influences of supernatural powers. Health-seeking behaviors are related to the perceived causes of the disease, economic factors, and the accessibility of health services.

    Issues regarding water pollution in rural areas of China have garnered increased attention over the years. Further discussion on the circumstances and results of existing domestic sewage treatment methods may serve as an appropriate reference in solving these important issues. This article explored the current conditions of water contamination in rural areas of China, introduced the characteristics and effects of applicable sewage treatment technology, and summarized the results of the planning, installation, and operation of rural sewage treatment facilities in Yongjia County in Zhejiang Province. However, relying on a single technical design rule is not adequate for solving the practical problems that these villages face. Instead, methods of planning rural sewage treatment should be adapted to better suit local conditions and different residential forms. It is crucial, ultimately, for any domestic sewage treatment system in a rural area to be commissioned, engineered, and maintained by a market-oriented professional company.

    The Eastern Coal Province is divided into 24 hydrologic reporting areas. This report describes the hydrology of area 18 which is located in the Cumberland River basin in central Tennessee near the southern end of the Province. Hydrologic information and sources are presented as text, tables, maps, and other illustrations designed to be useful to mine owners, operators, and consulting engineers in implementing permit applications that comply with the environmental requirements of the ' Surface Mining Control and Reclamation Act of 1977. ' Area 18 encompasses parts of three physiographic regions; from east to west the Cumberland Plateau, Highland Rim, and Central Basin. The Plateau is underlain by sandstones and shales, with thin interbedded coal beds, of Pennsylvanian age. The Highland Rim and Central Basin are underlain by limestone and dolomite of Mississippian age. Field and laboratory analyses of chemical and physical water-quality parameters of streamflow samples show no widespread water quality problems. Some streams, however, in the heavily mined areas have concentrations of sulfate, iron, manganese, and sediment above natural levels, and pH values below natural levels. Mine seepage and direct mine drainage were not sampled. Ground water occurs in and moves through fractures in the sandstones and shales and solution openings in the limestones and dolomites. Depth to water is variable, ranging from about 5 to 70 feet below land-surface in the limestones and dolomites, and 15 to 40 feet in the coal-bearing rocks. The quality of ground water is generally good. Locally, in coal-bearing rocks, acidic water and high concentrations of manganese, chloride, and iron have been detected. (USGS)

  19. Assessing the Impacts of Wind Integration in the Western Provinces

    NASA Astrophysics Data System (ADS)

    Sopinka, Amy

    Increasing carbon dioxide levels and the fear of irreversible climate change has prompted policy makers to implement renewable portfolio standards. These renewable portfolio standards are meant to encourage the adoption of renewable energy technologies thereby reducing carbon emissions associated with fossil fuel-fired electricity generation. The ability to efficiently adopt and utilize high levels of renewable energy technology, such as wind power, depends upon the composition of the extant generation within the grid. Western Canadian electric grids are poised to integrate high levels of wind and although Alberta has sufficient and, at times, an excess supply of electricity, it does not have the inherent generator flexibility required to mirror the variability of its wind generation. British Columbia, with its large reservoir storage capacities and rapid ramping hydroelectric generation could easily provide the firming services required by Alberta; however, the two grids are connected only by a small, constrained intertie. We use a simulation model to assess the economic impacts of high wind penetrations in the Alberta grid under various balancing protocols. We find that adding wind capacity to the system impacts grid reliability, increasing the frequency of system imbalances and unscheduled intertie flow. In order for British Columbia to be viable firming resource, it must have sufficient generation capability to meet and exceed the province's electricity self-sufficiency requirements. We use a linear programming model to evaluate the province's ability to meet domestic load under various water and trade conditions. We then examine the effects of drought and wind penetration on the interconnected Alberta -- British Columbia system given differing interconnection sizes.

  20. The province and heritage of mankind reconsidered: A new beginning

    The central problem of our time -- one that is shared by all races and nationalities -- is to discover the things, the qualities, and interest that people have in common so that durable institutions can be designed for mankind's survival. The 'common heritage of mankind' and the 'province of all mankind' are different legal concepts developed in international space law during the last quarter of a century. Since the initial appearance of these provisions, controversy has arisen regarding their intent and meaning as applied to a nation's right to explore and use a common environment such as space or the high seas and a nation's obligation to share benefits derived from those environments with the rest of the world. As can be expected, different interpretations are currently competing for acceptance. This is so, in part, because, in the case of the Outer Space Treaty, although a general principle was articulated, rules for acceptance and application of the principles were not. In the case of the Moon and Sea Treaties, although an effort has been made to clarify both meaning and application, the articulations are still too vague for legal certainty. This paper focuses on the fact that these concepts are already currently available tools for the advancement of both global and U.S. interests but, because of the labyrinthine legal arguments that have been generated and some assumptions being held, they are in danger of being lost as such tools. The tendency of many observers in the U.S. to confuse the concept of 'province of all mankind' and 'common heritage of mankind' and to assume that both are incompatible with U. S. commercial space interests is also addressed. It is suggested that reconsidering these provisions can yield positions compatible with U.S. interests and that it can and should actively seek the use of these provisions as a basis for global cooperation and commercial benefit.

    The aim of this study was to examine the subtype distribution of human papilloma virus (HPV) in women in the Shaanxi Province of China. A DNA chip, along with polymerase chain reaction amplification and reverse dot blot technology, was adopted to analyze the HPV genotypes of 22,937 cases of cervical cell specimens. The HPV infection rate was 18.70%, wherein high-risk, low-risk, and high- and low-risk multiple infection rates were 15.75, 2.96 and 1.91%, respectively. High-risk infections accounted for 84.20% of total infections. The rate of HPV infection in women with rural residence, high school education or less, a low income, or age over 40 years was significantly higher than that in the control group (negative HPV infection women). Of the 18 detected high-risk HPV subtypes, the most common in single infections were, in the order of prevalence, HPV16, 58, 18, 52, 33, and 56. For multiple high-risk infections, the most common subtypes in the order of prevalence were HPV16, 52, 58, 18, 56, and 33. Age was a factor in the rate of infection, as the 41-50-year age group had a significantly higher risk of infection than the other groups (P < 0.05). In multiple infections, double infections were common, accounting for 77.10% of multiple infections, and triple or more infections were more common in women aged 51-60 years. In Shaanxi Province, high-risk HPV infection in women was mainly attributed to rural residence, age over 40 years, low income, and low education level.

    Background: The rapid rise in noncommunicable diseases (NCDs) is one of the main health challenges affecting the global development in the present era. This raising challenge is a major threat to countries’ socioeconomic development as well as millions of people health. Methods: It was a retrospective study with analysis of reported death in Isfahan Province during a 5-year period from 2007 to 2011. Required data were collected from statistics provided by Deputy of Health in Kashan and Isfahan Universities of Medical Sciences in 2012. Excel software was used for data analysis. Results: During this period, the cardiovascular events, cancers and tumors, unintentional injuries, respiratory diseases, and prenatal mortality were the main reasons of mortality in Isfahan Province. The overall rate of cardiovascular events rose 5.10% in the 5-years of the study observation, and Khor – Biabanak was on the top of the list; while in cancer rating Khor – Biabanak, Golpayegan, and Khansar both stood at the outset (per 1,000 people). For injuries, the highest rate belonged to Golpayegan, Tiran-Kervan, and Chadegan. Meanwhile, for mental illnesses, the highest rate was observed in Khomeini Shahr. Moreover, the highest maternal and fetal mortality was reported in Fereydunshahr, Khor – Biabanak and Mobarakeh. Conclusions: Given the sharp rise of NCD, programs by health care system should be directed toward lifestyle modification while a proper framework should be determined to deal with these kinds of disease. Furthermore, optimal allocation of resources based on needs can provide better facilities for different cities. PMID:27563432

    Human activities produced great impacts on wetlands worldwide. Taking Jiangsu Province, China, as a representative wetland region subject to extensive human activities, the aim of this study is to understand the conversion trajectory and spatial differentiation in wetland change from a multi-scale perspective. Based on multi-temporal Landsat images, it was found that the natural wetlands decreased by 11.2% from 1990 to 2006 in Jiangsu Province. Transition matrices showed that the conversion of natural wetlands to human-made wetlands (mostly aquaculture ponds) was the major form of natural wetland reduction, accounting for over 60% of the reduction. Percentage reduction and area reduc tion of natural wetlands were respectively quantified within different wetland cover zones using a moving window analysis. Average percentage reduction showed a decreasing tendency with increasing wetland cover. The high-cover and mid-cover zone presented the largest area reduction at the scales of 1-2 km and 4-8 km, respectively. Local hotspots of natural wetland reduction were mapped using the equal-interval and quantile classification schemes. The hotspots were mostly concentrated in the Lixiahe marshes and the coastal wetland areas. For the area reduction hotspots, the quantile classification presented larger area and more patches than the equal-interval classification; while an opposite result was shown for the percentage reduction hotspots. With respect to the discontinuous distribution of the natural wetlands, area reduction could be more appropriate to represent reduction hotspots than percentage reduction in the study area. These findings could have useful implications to wetland conservation.

    Background The burden of cancer affects all countries; while high-income countries have the capacity and resources to establish comprehensive cancer control programs, low and middle-income countries have limited resources to develop such programs. This paper examines factors associated with the development of cancer registries in four provinces in Turkey. It looks at the progress made by these registries, the challenges they faced, and the lessons learned. Other countries with similar resources can benefit from the lessons identified in this case study. Methods A mix of qualitative case study methods including key informant interviews, document review and questionnaires was used. Results This case study showed that surveillance systems that accurately report current cancer-related data are essential components of a country’s comprehensive cancer control program. At the initial stages, Turkey established one cancer registry with international support, which was used as a model for other registries. The Ministry of Health recognized the value of the registry data and its contribution to the country’s cancer control program and is supporting sustainability of these registries as a result. Conclusions This study demonstrates how Turkey was able to use resources from multiple sources to enhance its population based cancer registry system in four provinces. With renewed international interest in non-communicable diseases and cancer following the 2011 UN high-level meeting on NCDs, low- and middle- income countries can benefit from Turkey’s experience. Other countries can utilize lessons learned from Turkey as they address cancer burden and establish their own registries. PMID:23110989

    Dengue is endemic and affects people in all Indonesian provinces. Increasing dengue cases have been observed every year in Sukabumi in West Java province. Despite the endemicity, limited data is available on the genetic of dengue viruses (DENV) circulating in the country. To understand the dynamics of dengue disease, we performed molecular and serological surveillance of dengue in Sukabumi. A total of 113 patients were recruited for this study. Serological data were obtained using anti-dengue IgM and IgG tests plus dengue NS1 antigen detection. Dengue detection and serotyping were performed using real-time RT-PCR. Viruses were isolated and the envelope genes were sequenced. Phylogenetic and evolutionary analyses were performed to determine the genotype of the viruses and their evolutionary rates. Real-time RT-PCR detected DENV in 25 (22%) of 113 samples. Serotyping revealed the predominance of DENV-2 (16 isolates, 64%), followed by DENV-1 (5 isolates, 20%), and DENV-4 (4 isolates, 16%). No DENV-3 was detected in the samples. Co-circulation of genotype I and IV of DENV-1 was observed. The DENV-2 isolates all belonged to the Cosmopolitan genotype, while DENV-4 isolates were grouped into genotype II. Overall, their evolutionary rates were similar to DENV from other countries. We revealed the distribution of DENV serotypes and genotypes in Sukabumi. Compared to data obtained from other cities in Indonesia, we observed the differing predominance of DENV serotypes but similar genotype distribution, where the infecting viruses were closely related with Indonesian endemic viruses isolated previously.

    Introduction Preterm labor is the main cause of infants’ death, and the main reason for undesirable consequences of pregnancy which still occur in some births, despite all of the interventions in this regard. The aim of this study was to evaluate every preterm birth and determine its maternal risk factors in Hormozgan province in 2013. Methods This case-control study was conducted in 2013 on the health and hospital records of 735 pregnant mothers with preterm labor (20–37 weeks) which were located in Bandar Abbas in southeast Iran. The sampling method would be multi-stage cluster sampling. The data collecting tool was a valid questionnaire by the Iran Ministry of Health and Medical Education, which included 5 components (demographic information, checking the current pregnancy of the mother, the maternal factors related to preterm labor in the previous pregnancy, evaluating the fetal factors associated with preterm labor in the current pregnancy and other additional information related to the factors associated with prematurity). Data were analyzed using descriptive statistics, regression and Chi-square tests Results The prevalence of preterm labor in Hormozgan province in 2013 was 5.5%. In our study and among the effective factors on preterm labor, revealed genital-urinary tract infections during pregnancy were (35.8%), PROM (30.3%), history of abortion (19.9%) and unplanned pregnancy (18.1%) in between pregnant women with preterm labor. Our study showed that most mothers had delivered in 33 to 37 weeks among the mothers who had preterm labor in 2013 (75%) and the statistic of very preterm labor (less than 32 weeks) in Hormozgan was 5%. Conclusion Identification of the prevalence and associated factors with preterm labor can reduce the mortality rate and infants’ complications of it in addition to help find a way to prevent this problem.

    The primary objective of this study was to determine the prevalence of Metabolic Syndrome (MS) in people between 40-70 years of age in the province of Albacete (Spain). A population-based, cross-sectional study was made of people between 40-70 years of age in three representative municipalities of the province of Albacete. A total of 425 subjects were included, with a mean age of 53.1 years (95% CI: 52.3-54). Women represented 50.4% of the series and males 49.6%. All participants were subjected to general laboratory testing, physical examination and the measurement of anthropometric parameters. MS was defined according to the ATP-III criteria. Prevalence of MS and its distribution according to the different epidemiological characteristics were calculated. Total prevalence of MS was 20.9% (88/421), with a mean age of 57 years (95% CI: 55.1-59). Prevalence was seen to increase with age, reaching up to one-third of all subjects over 60 years. Significant differences were observed in relationship to a background of ischemic heart disease, ultrasensitive C-reactive protein elevation and the detection of microalbuninuria in MS subjects. Arterial hypertension and abdominal obesity were the most prevalent criteria in MS subjects. Taking into consideration the important co-morbidity of MS, knowledge of the prevalence and characteristics of the syndrome in our setting and its early identification and intervention targeted to the different factors underlying MS will contribute to reduce the number of cardiovascular events associated with the syndrome.

    Contrary to general belief, not all large igneous provinces (LIPs) are characterised by rocks of basaltic composition. Silicic-dominated LIPs, such as the Whitsunday Volcanic Province of NE Australia, are being increasingly recognised in the rock record. These silicic LIPs are consistent in being: (1) volumetrically dominated by ignimbrite; (2) active over prolonged periods (40-50 m.y.), based on available age data; and (3) spatially and temporally associated with plate break-up. This silicic-dominated LIP, related to the break-up of eastern continental Gondwana, is also significant for being the source of >1.4×10 6 km3 of coeval volcanogenic sediment preserved in adjacent sedimentary basins of eastern Australia. The Whitsunday Volcanic Province is volumetrically dominated by medium- to high-grade, dacitic to rhyolitic lithic ignimbrites. Individual ignimbrite units are commonly between 10 and 100 m thick, and the ignimbrite-dominated sequences exceed 1 km in thickness. Coarse lithic lag breccias containing clasts up to 6 m diameter are associated with the ignimbrites in proximal sections. Pyroclastic surge and fallout deposits, subordinate basaltic to rhyolitic lavas, phreatomagmatic deposits, and locally significant thicknesses of coarse-grained volcanogenic conglomerate and sandstone are interbedded with the ignimbrites. The volcanic sequences are intruded by gabbro/dolerite to rhyolite dykes (up to 50 m in width), sills and comagmatic granite. Dyke orientations are primarily from NW to NNE. The volcanic sequences are characterised by the interstratification of proximal/near-vent lithofacies such as rhyolite domes and lavas, and basaltic agglomerate, with medial to distal facies of ignimbrite. The burial of these near-vent lithofacies by ignimbrites, coupled with the paucity of mass wastage products such as debris-flow deposits indicates a low-relief depositional environment. Furthermore, the volcanic succession records a temporal change in: (1) eruptive styles

    Objective Population-based cancer registration data in 2012 from all available cancer registries in Shandong province were collected by Shandong Center for Disease Control and Prevention (SDCDC). SDCDC estimated the numbers of new cancer cases and cancer deaths in Shandong province with compiled cancer incidence and mortality rates. Methods In 2015, there were 21 cancer registries submitted data of cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the National Central Cancer Registry (NCCR) criteria of data quality. Qualified data from 15 registries were used for cancer statistics analysis as provincial estimation. The pooled data were stratified by area (urban/rural), gender, age group (0, 1.4, 5.9, 10.14, …, 85+ years) and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding provincial population in 2012. The Chinese census data in 2000 and Segi’s population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year. Results Qualified 15 cancer registries (4 urban and 11 rural registries) covered 17,189,988 populations (7,486,039 in urban and 9,703,949 in rural areas). The percentage of cases morphologically verified (MV%) and death certificate-only cases (DCO%) were 66.12% and 2.93%, respectively, and the mortality to incidence rate ratio (M/I) was 0.60. A total of 253,060 new cancer cases and 157,750 cancer deaths were estimated in Shandong province in 2012. The incidence rate was 263.86/100,000 (303.29/100,000 in males, 223.23/100,000 in females), the age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 192.42/100,000 and 189.50/100,000 with the cumulative incidence rate (0.74 years old) of 22.07%. The cancer incidence, ASIRC and ASIRW in urban areas were 267.64/100,000, 195.27/100,000 and 192.02/100,000 compared to 262.32/100,000, 191.26/100,000 and 188.48/100,000 in

    The present study aims to calibrate radiation-based methods to determine the best method under different weather conditions. For this purpose, weather data was collected from different synoptic stations in all of provinces of Iran. The potential evapotranspiration was estimated using common radiation-based methods and a sensitive analysis was done for investigating variations of the methods. The results show that the Stephens method estimates the potential evapotranspiration better than other methods in the most provinces of Iran (10 provinces). However, the values of R 2 were less than 0.98 for 15 provinces of Iran. The calibrated methods estimated the potential evapotranspiration in the south east of Iran better than other provinces. Precision of the methods calibrated has been increased in all provinces. The R 2 values are less than 0.98 for only six provinces (WA, EA, GO, NK, AL, and QO). In the methods calibrated, the Abtew (for YA) estimated the potential evapotranspiration better than the other methods.
