    To describe speech disorders in students from 1st to 4th grades, and to investigate possible associations between these disorders and stomatognathic system and auditory processing disorders. Cross-sectional study with stratified random sample composed of 288 students, calculated based on an universe of 1,189 children enrolled in public schools from the area covered by a health center in Belo Horizonte. The median age was 8.9 years, and 49.7% were male. Assessment used a stomatognathic system protocol adapted from the Myofunctional Evaluation Guidelines, the Phonology task of the ABFW - Child Language Test, and a simplified auditory processing evaluation. Data were statistically analyzed. From the subjects studied, 31.9% had speech disorder. From these, 18% presented phonetic deviation, 9.7% phonological deviation, and 4.2% phonetic and phonological deviation. Linguistic variation was observed in 38.5% of the children. There was a higher proportion of children with phonetic deviation in 1st grade, and a higher proportion of children younger than 8 years old with both phonetic and phonological deviations. Phonetic deviation was associated to stomatognathic system disorder, and phonological deviation was associated to auditory processing disorder. The prevalence of speech disorders in 1st to 4th grade students is considered high. Moreover, these disorders are associated to other Speech-Language Pathology and Audiology alterations, which suggest that one disorder may be a consequence of the other, indicating the need for early diagnosis and intervention.

    Objectives: To describe the prevalence of sickness absence and to analyze factors associated with the outcome according to gender in a sample of healthcare workers at the Belo Horizonte Health Department. Method: This study was based on a Belo Horizonte Health Department survey carried out between September 2008 and January 2009. From a randomly selected sample of 2,205 workers, 1,808 agreed to participate. Workers were classified into Health Staff or Health Care. Other explanatory variables were social and demographic data, work characteristics, and personal health. The Poisson regression was applied to analyze factors associated with sickness absence by the prevalence ratio (PR). Results: The overall prevalence of sickness absence was 31.5% (23.8% for men and 34.6% for women). In the final model, we found higher rates of sickness absence in both male and female workers involved in tasks with high psychosocial demands (PR=1.86 men; PR=1.38 women) and in those that reported using medication for treating chronic diseases (PR=1.96 men; PR=1.50 women). Women having a permanent job contract had a higher prevalence of sickness absence than those having a temporary job contract (PR=1.71). Conclusion: Our findings suggest a paradox in how healthcare is organized: good results in terms of its global objective of providing healthcare for citizens contrast with lack of effective measures for protecting healthcare workers.

    The ultraviolet radiation (UVR) emitted by the Sun causes many effects on the biosphere. On human beings they vary from the benefit of vitamin D synthesis to the harm of skin cancer induction. The biological dose depends on the effect, the exposure time to the Sun and the amount of UVR received. In this work we show that the measured incidence of erythemal dose (ED) in Belo Horizonte (19.92 degrees S, 43.94 degrees W, 858 m a.s.l., Brazil) for a cloudless day can vary from 7503 to 2926 J m(-2) in the summer-winter seasonal variation. In addition, supposing a linear relationship between the ED and the geophysical parameters of solar zenith angle cosine (cos(SZA)), column ozone and reflectivity from the ozone monitoring instrument overpass measurements, a model for the forecast of UVR incidence on a monthly-based period is developed. From this an annual ED of 1,451,099 J m(-2) is obtained.

    Rhipicephalus sanguineus ticks are distributed throughout the world, especially in those areas in which dogs are in close contact with humans. R. sanguineus and fleas are regarded as the main ectoparasites infesting dogs in Brazil. Besides causing direct damage during the blood feeding process, this tick species can also transmit pathogens to dogs and humans. Despite its importance in Brazil, data regarding the seasonality of R. sanguineus are limited, especially with regard to natural infestations of dogs. The present study aimed to evaluate the seasonality of R. sanguineus on dogs living in Belo Horizonte, state of Minas Gerais. From August 2006 to July 2007, ticks were collected monthly from 12 adult dogs in nine houses, which were located in two districts in the north region of the city. In parallel, canine clients of a pet care department of the small animal veterinary clinic were examined for the presence of ticks before bathing and/or clipping. The climatic data recorded for Belo Horizonte during the experimental period were: mean temperature 18.6 degrees C; relative air humidity 56.5%; rainfall 37mm. The only species of ticks identified from all infested dogs was R. sanguineus, which was found in all its development stages. Among dogs living in houses, three tick population peaks were observed (August, February, and June), suggesting the occurrence of three generations per year in Belo Horizonte. A total of 7318 ticks were collected, of which 5422 were adult ticks and 1896 represented immature stages (744 larvae and 1152 nymphs). The monthly inspection of dogs living in houses demonstrated significantly higher parasitism during the dry season (p<0.05). A total of 2848 dogs from the pet care department of the small animal veterinary clinic were examined, of which 222 (7.8%) were infested with ticks and the percentage of infested dogs in the dry season was higher (p<0.05) than in the hot wet. The percentage of male dogs infested with ticks was significantly

    The scope of this article is to assess the nutritional status of users of low-budget restaurants and soup kitchens in Belo Horizonte and to identify factors associated with being overweight. It involved a cross-sectional analytical study conducted among adults of both sexes in low-budget restaurants and soup kitchens in Belo Horizonte. Being overweight was the dependent variable and was defined as body mass index (BMI) ≥ 25 kg/m2. This was correlated with socio-demographic variables and the level of physical activity. The data were obtained directly through weight and height measurement and a semi-structured questionnaire. The study involved 1334 individuals, the majority being male. The prevalence of being overweight was 42.9% among the men and 45.8% among the women. The following factors were positively associated with being overweight: being older for both sexes; having a partner for the women; taking less physical exercise and higher socioeconomic level for the men. Detection of factors associated with being overweight reveals that there is a need to implement an effective systematic program of dietary and nutritional education in order to prevent and remedy this condition, so that low-budget restaurants fulfill their objective.

    This study analyzed the association between self-reported diagnosis of hearing loss and individual and occupational factors among urban transportation workers in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The sample size was calculated by quotas and stratified by occupation (drivers and fare collectors) in the urban transportation companies in Belo Horizonte, Betim, and Contagem. Data were collected with face-to-face interviews and recorded by the interviewers on netbooks. The dependent variable was defined as an affirmative response to the question on prevailing medical diagnosis of hearing loss. The independent variables were organized in three blocks: social and demographic characteristics, lifestyle, and work aspects. Diagnosis of hearing loss was reported by 213 of the 1,527 workers and was associated with age and diagnosis of tinnitus. At the occupational level, hearing loss was associated with history of sick leave, time-on-the-job, and two environmental risks, unbearable noise and whole-body vibration. Measures to prevent hearing loss are needed for urban transportation workers.

    There are few published studies about the effects of inadequate solid waste collection on the health of the population exposed to this situation. The objective of the present work was to describe this association in a sample of children under 5 years of age living in seven low-income neighborhoods and favelas in the city of Belo Horizonte, state of Minas Gerais, Brazil. We defined as "exposed" those children whose families were not served by waste collection; "not-exposed" were children who lived in areas with waste collection. The study employed data collected in 1994 and organized as a database by the municipal department of health. We employed a cross-sectional design, in which a "case" was defined as a child whose outpatient clinic record indicated a diagnosis of diarrheal, parasitic, or dermatological disease. Other diagnoses for the same age group composed the control group. Our epidemiological study revealed an association between the absence of domestic solid waste collection and public health. Our results suggest that the children exposed to the absence of solid waste collection have a 40% higher odds (OR = 1.40) of presenting diarrheal, parasitic, and dermatological diseases than not-exposed children. In addition, the calculation of attributable risk revealed that the presence of waste collection could prevent (based on the 1995 situation) 512 cases in the neighborhoods studied and (based on the 1994 conditions) 2316 cases among children in the entire city of Belo Horizonte.

    A study on the phlebotomine sand fly fauna in Belo Horizonte city, state of Minas Gerais, Brazil, was carried out. From April 2001 to March 2003, monthly systematic collections were performed in three houses from each of the nine regions of the city, using CDC light traps for four consecutive days. The traps were set into the houses and in peridomestic areas totaling 54 traps. A number of 3871 sand fly specimens of the genera Lutzomyia and Brumptomyia were collected. Sixty eight percent of the specimens were L. longipalpis and 16% L. whitmani, insect vectors of visceral and American cutaneous leishmaniasis, respectively. Environmental factors such as temperature, humidity, and frequency of precipitation suggest that the number of insects increases after rainy periods. During the same period mentioned above, seasonal captures were carried out in parks and green areas of Belo Horizonte, using Shannon trap. A total of 579 phlebotomine sand flies were collected from which 398 (68.7%) were females with the predominance of L. whitmani and L. monticola. Those specimens were used for natural infection examination, by polymerase chain reaction. No Leishmania DNA was present in any of the specimens tested.

    The Belo Horizonte Observatory for Urban Health (OSUBH), housed in an academic setting, was founded in 2002 as part of a broader agenda to strengthen local and national health systems. Its mission is to build the capacity of the workforce in research on population health and to conduct studies on urban issues that can guide the planning of activities aimed at improving the health of populations, especially in heavily urbanized areas, associated with intra-urban inequalities. It focuses on the acquisition of advanced knowledge on urban health (metric) through scientific research, to contribute to public policies that may interfere with health, both at individual and community levels. During its lifetime, many partnerships and studies have been developed, but many challenges still exist in order for it to consolidate its position as a legitimate space and as a tool to generate systematic information for governments and populations.

    . An 8-year climatological analysis (1989-1996) of lightning network data over Belo Horizonte, a large city located in Southeastern Brazil, and nearby surrounding areas has indicated a significant enhancement of approximately 100% in the negative flash density and of 50% in the positive flash density over and downwind of the city, compared with the other adjacent areas. A decrease of 25% in the percentage of positive flashes was also observed over and downwind of the city. No urban effect was evident in the peak current of both negative and positive flashes. These results are in agreement with the recent results obtained by Steiger et al. (2002) for Houston, except that the strength of the effect is twice larger than in Houston. The reason for this difference is not clear.

    Even after the publication of Law 8213 in 1991, which established quotas for employing disabled persons, their inclusion in the workplace still presents a challenge for Brazilian society. In order to understand the main barriers that hamper this process a qualitative research study was conducted in the municipality of Belo Horizon-te. This study included interviews with important actors involved in the process of inclusion; and focus groups including disabled persons and members of their families. The main barriers encountered were: preconceived ideas and discrimination; family relationships; the Continuous Cash Benefit (BPC) program; the low level of qualifi-cation among disabled person; lack of access; and the unpreparedness of companies. It was concluded that drafting laws is not sufficient to guarantee inclusion in the labor market and that governments should implement public policies to assist in this process.

    This study considers the dengue occurrence in the city of Belo Horizonte over the last fifteen years. Approximately 186,000 cases registered from 1996 to 2011 were analyzed. The home address of individuals whose dengue case was notified was used as a proxy for exposure location. For determining possible outbreaks of disease and the specific patterns of dengue cases, spatial statistics used included Kernel's estimation. The occurrence of waves of dengue outbreaks was correlated with climatic and vector presence data. Outbreaks had different durations and intensities: case clustering, thinned out both spatially and temporally. These findings may be useful for public health professionals responsible for fighting the disease providing some tools for improving evaluation of interventions such as vector control and patient care, minimizing the collective and individual burden of the disease.

    To analyze the infant mortality trend in a metropolitan area, from 1984 to 1998. The main focus was on avoidable causes of neonatal and post-neonatal mortality. Sources of data were the Sistema de Informacoes em Mortalidade do Ministerio da Saude (SIM-MS) [Mortality Information System of the Ministry of Health] and Fundacao Instituto Brasileiro de Geografia e Estatistica (IBGE) [Brazilian Institute of Geography and Statistics Foundation] (official live birth and death records) for the metropolitan region of Belo Horizonte, in the State of Minas Gerais. A simple linear regression model was used to evaluate time-trends of mortality rates. Statistical significance of the inclination of the regression curves was considered for the p<0.05 level. During the 15 year period in question, the infant mortality rate declined from 48.5 to 22.1/1,000 live births. However, the most accentuated decrease was observed during the last four years of the study period. The post-neonatal group was greatly responsible for this decline both in the capital and in the other districts within the metropolitan region of Belo Horizonte. Although a significant decrease in the infant mortality rate has been observed, particularly in the post-neonatal mortality, it is still larger than the rates found in developed countries. Deaths due to perinatal morbidities as well as the group of causes represented by diarrhea-pneumonia-malnutrition still present an important potential for reduction. The authors discuss the role of the health services in improving the rates of these avoidable causes of infant mortality.

    We evaluated, from anthropometric and biochemical indicators, the prevalence of undernutrition within an elderly population hospitalized in Belo Horizonte, Minas Gerais, Brazil, and identified social demographic, clinical and biochemical factors associated with undernutrition. A transverse sectional study involving 197 elderly patients was conducted. Anthropometric data were obtained from subjects directly or indirectly; clinical characteristics, including health problems, functional and cognitive abilities, and use of medication, were gathered from medical records; social demographic information was acquired by interviewing the subject or carer. Logistic regression analysis was employed to identify factors associated with undernutrition. According to the body mass index cutoff points recommended by the World Health Organization, 29.7% of subjects were classified as undernourished and 43.8% as eutrophic. Application of the Nutrition Screening Initiative system gave rise to an inverse situation in which 54.7% of subjects were considered undernourished and only 29.2% were eutrophic. Statistical analysis of the studied variables showed that calf circumference < or =31 cm was significantly associated with undernutrition (P < 0.0001) irrespective of the classification system employed, and may thus be considered a strong marker for undernutrition. In contrast, total serum cholesterol level > or =4.14 mmol/L was identified as a protective factor against undernutrition (P = 0.01). The prevalence of undernutrition among the hospitalized elderly in Brazil is very high. The measurement of calf circumference is a non-invasive and economical approach that can facilitate evaluation of the nutritional status of elderly individuals.

    Exposed to many occupational risk factors, the anesthesiologist should know how to experience situations related to work and everyday life, so that illness is not part of his reality. Knowledge of work through the worker himself is one way to look deeper into the universe surrounding health professionals in order to seek effective solutions that increase satisfaction and minimize damage. The objective of this paper was to outline an epidemiological and occupational profile of the anesthesiologist in Belo Horizonte, Minas Gerais. Quantitative, cross-sectional randomized study conducted among members of the Society of Anesthesiology of Minas Gerais. Data collected through a questionnaire, including the CAGE, for evaluation of alcoholism and Self-Report Questionnaire (SRQ-20) to evaluate the prevalence of common mental disorders (CMD). There was predominance of male (62.4%) working on-call schedule (91.1%), both day and at night. The average number of night shifts was 5.4% in the last 30 days. Most of them (88.3%) working in emergency departments. Most professionals reported being very tired and overloaded or very overloaded, but satisfied with the work. There was statistical association between CAGE positive and work overload and between CAGE and SRQ-20. The population studied indicates that the anesthesiologist is a professional rather overloaded, which corroborates trends seen in the medical field. Major attention should be given to these professionals who live surrounded by harmful occupational hazards. Copyright © 2012 Elsevier Editora Ltda. All rights reserved.

    The aim of this study was to assess the major food items ingested by adult specimens of Daphnia laevis within the eutrophic Pampulha reservoir in Belo Horizonte, Minas Gerais, Brazil. The gut content was analyzed after addition of sodium hypochlorite and also through the examination of dissected guts under scanning electron microscopy. The results showed that Chlorophyceae was the main food item ingested, representing c. 80.5% of the total ingested food. Moreover, Eutetramorus fottii, Coelastrum pseudomicroporum and Oocystis lacustris, the dominant phytoplankton species within the reservoir, were the most frequent cells found in the gut contents. Euglenophyta also represented an important food item accounting for 15% of the ingested material, including mainly Trachelomonas volvocina and Euglena oxyuris, although less abundant in the reservoir (< 10% of total phytoplankton). Blue-green algae occurred at much lower percentages in the guts than in the phytoplankton. A small amount of undigested Microcystis aeruginosa colonies were also found in the gut content of D. laevis. Scanning electron microscopy results showed that, besides phytoplankton cells, a great amount of abiogenic material was also ingested. The amount of this inorganic material increased considerably in the tract (from 15% to 75% of the gut content), when a peak of D. laevis was observed in the reservoir. Our assumption is that the ingestion of this inorganic material can be a strategy used by D. laevis to obtain additional food supply.

    To identify factors associated with vaccination against hepatitis B among healthcare workers. This was a cross-sectional study on 1,808 public-sector healthcare workers in Belo Horizonte, Southeastern Brazil, in 2009. A self-administered questionnaire was used and the vaccination situation was analyzed taking sociodemographic characteristics, lifestyle and working conditions and characteristics into consideration. Univariate (p < 0.20) and multiple (p < 0.05) statistical analyses were performed using Poisson regression to evaluate factors associated with vaccination. Of the workers, 85.6% declared that they had been vaccinated, although only 74.9% of the vaccinated professionals had received a complete immunization schedule. Not having been vaccinated was associated with not having a partner; having high school, technical or incomplete higher education level; work characteristics such as working in surveillance or the administrative/general services sector; and not using personal protection equipment. Groups with lower vaccination coverage were identified. Efforts are required to ensure access and adherence to vaccination among healthcare workers, such as awareness-raising mechanisms.

    As more urban solid waste is generated, managing it becomes ever more challenging and the potential impacts on the environment and human health also become greater. Handling waste - including collection, treatment and final disposal - entails risks of work accidents. This article assesses the perception of waste management workers regarding work-related accidents in domestic and health service contexts in Belo Horizonte, Brazil. These perceptions are compared with national data from the Ministry of Social Security on accidents involving workers in solid waste management. A high proportion of accidents involves cuts and puncture injuries; 53.9% among workers exposed to domestic waste and 75% among those exposed to health service waste. Muscular lesions and fractures accounted for 25.7% and 12.5% of accidents, respectively. Data from the Ministry of Social Security diverge from the local survey results, presumably owing to under-reporting, which is frequent in this sector. Greater commitment is needed from managers and supervisory entities to ensure that effective measures are taken to protect workers' health and quality of life. Moreover, workers should defend their right to demand an accurate registry of accidents to complement monitoring performed by health professionals trained in risk identification. This would contribute to the improved recovery of injured workers and would require managers in waste management to prepare effective preventive action.

    To analyze the contribution of three data sources in the description of traffic accidents in the city of Belo Horizonte, Brazil. Exploratory study of databases: BHTRANS (metropolitan traffic and transportation authority), Hospital Admissions and Mortality Information Systems, with estimation of proportions, coefficients and odds ratios. Incomplete data was observed in the three sources, especially regarding alcohol consumption by drivers and use of safety equipment. The victim profile among the sources was consistent: young adults, males, motorcycle riders and pedestrians. In addition to the high mortality rate (19.4 per 100.000 inhabitants), an increase in the number of non-fatal accidents was observed. An increase of 34% in hospital admissions and of 53% in hospital costs was evidenced. The motorcycle accident rate is higher than expected given the fleet composition. Male drivers have the highest risk of injury or death; relative to drivers, passengers or pedestrians have a 1,8 times higher risk of death. There was a 12% increase in the number of deaths at the site of the accident, 55% of which showed positive evidence of alcohol use and 50% higher risk of fatal accidents on weekends. Despite some incomplete record keeping and non-specific death registry codes, it was possible to characterize the main factors associated with accidents: elderly pedestrians, motorcycle riders, alcohol consumption and speeding. The study demonstrated the complementarity of the three data sources, with their different goals, and revealed important features of the traffic accident event-chain and victim profile, providing key data for the development of mitigation strategies.

    Infection with the hepatitis B and C viruses may occur through contact with infected body fluids, including injury with infected sharps. Collectors of domestic or healthcare wastes are potentially exposed to these infections. The aim of this article is to investigate the risk factors associated with the prevalence of hepatitis B and C viruses (HBV and HCV) infection among domestic and healthcare waste workers in Belo Horizonte, Brazil. A cross-sectional study of hepatitis B and C infection was conducted from November 2014 to January 2015, through blood sample collection and interviews about socio-demographic factors with 61 workers exposed to healthcare waste ('exposed') and 461 exposed only to domestic wastes ('unexposed'). The prevalence of antibodies to HCV (Anti-HCV) antibodies was 3.3% in 'exposed' workers and 0.9% in 'unexposed', and of antibody to hepatitis B core antigen (Anti-HBc) was 9.8% and 5.6% in 'exposed' and 'unexposed' workers, respectively. Only 207 (44.9%) of those exposed to domestic waste and 45 (73.8%) of those handling healthcare waste were effectively immunised against hepatitis B virus (HBV). Exposures to domestic waste and to healthcare wastes were associated with similar risks of infection with HBV. The risk of hepatitis C virus (HCV) infection was marginally higher among healthcare waste workers compared with domestic waste workers, probably because of needlestick accidents owing to deficient sharps management systems. Immunisation against hepatitis B and screening tests to ensure the success of vaccination should be a condition for recruitment for both groups of waste workers.

    - Medical literature has shown dyspepsia and heartburn-related symptoms occur among 15% to 40% of the population. These symptoms can occur at any age and are more prevalent in women. - Investigate the prevalence of dyspeptic symptoms and heartburn among individuals over 18. - Individuals over 18 were randomly selected in public venues in Belo Horizonte/MG to participate. A standardized questionnaire that included questions related to social-demographic characteristics, eating habits, digestive symptoms, medical appointments, medications, exams, previous surgeries and comorbidities was applied. A questionnaire about functional dyspepsia diagnosis (Rome III) was also applied. - A total of 548 individuals were interviewed. Among these, 58.4% were women, 59.3% were white, 55.9% were single and the average age was 36 years. Within this group, 376 individuals (68.6%) declared to have some symptom and/or use medication to relieve dyspepsia symptoms, and for these patients were applied the Rome III questionnaire. Based on the diagnostic criteria for the questionnaire proposed by the Rome III consensus, the symptom of postprandial fullness was reported by 6.7% of the individuals, early satiety (3.5%) and epigastric pain (10.6%). The overlap of these symptoms was very frequent. The prevalence of functional dyspepsia was 10.6% (postprandial discomfort syndrome (8.2%) and epigastric pain syndrome (2.4%). Among all participants, 52.5% reported heartburn, and 11.1% presented this symptom at least once a week. The most used drug was omeprazole. - The prevalence of dyspeptic symptoms and heartburn among a Brazilian adult urban population is similar to those described in other countries.

    Background The fundamental importance of human resources for the development of health care systems is recognized the world over. Health districts, which constitute the middle level of the municipal health care system in the city of Belo Horizonte, Brazil, deal with demands from all parts of the system. This research seeks to provide the essential features required in order to understand the phenomenon of increase in precarity of employment in these health districts. Methods The legal and human resource management documents used by the Municipal Health Secretariat of the City of Belo Horizonte were adopted as the corpus for this research. In order to analyse the changes in employment (2002–2006), the data were collected from ArteRH, a computerized database dealing specifically with data related to human resources, which began operating in 2001. The workers were classified into permanent and non-permanent groups, and their contractual rights were described. Employment dynamics and changes were examined, concentrating on the incorporation of workers and on their social and employment rights during the period under study. The comparative data for the two groups obtained were presented in frequency distribution tables according to type of employment, sex, age group, level of education and wages from 2002 to 2006. Results There was a clear difference between the permanent worker and non-permanent worker groups as regards existing guaranteed employment rights and social security. The increase in the number of non-permanent workers in the workforce, the growing proportion of older workers among the permanently employed and the real wage reductions during the period from 2002 to 2006 are indicative of the process of growing precarity of employment in the group studied. Conclusion It is a plausible supposition that the demand for health reforms, along with the legal limits imposed on financial expenditure, gave rise to the new types of contract and the present employment

    Several reports have been published describing the occurrence of volatile N-nitrosamines in rubber products. The first evidence of the presence of these compounds in baby bottle nipples was published by Ireland et al. Their study showed the presence of N-nitrosamines in elastomers compounded with dialkylamine accelerators and stabilizers. Several countries, through active cooperation with industry, have made considerable progress in eliminating or significantly reducing the levels of N-nitrosamines in baby bottle nipples. The purpose of the present study was to investigate the occurrence of volatile N-nitrosamines in baby bottle rubber nipples in the market of Belo Horizonte, MG, Brazil.

    This research sought to understand meanings and implications of the stigma related to bipolar disorder in relation to social processes and local cultural value systems. Seven semidirected individual interviews were performed with psychiatrists (from Belo Horizonte city, Minas Gerais State, Brazil) and analyzed with referential from the Medical Anthropology. Some potential stigmatizing views about bipolar disorder patients were endorsed by respondents related to biomedical model of bipolar disorder. They claimed about the extreme trivialization of this diagnosis nowadays and observed that, in spite of the mitigation of stigma related to bipolar disorder over time, it remains an important issue, especially at labor fields and as a cause of refusal of treatment.

    The objective of this study is to establish the prevalence of dysphonia and associated factors in public school female teachers working in Belo Horizonte. This cross-sectional study was conducted on a random sample of schools between May 2004 and July 2005. There were 2103 elementary education daytime teachers from 83 schools included in the study. Self-applied questionnaires were used for data collection. These included questions on social and demographic matters, general health and mental health (General Health Questionnaire-12 [GHQ-12]), the environment and organization of work, and voice-related aspects. The variable dysphonia was classified as absent, possible, or probable based on the association between frequency of fatigue when speaking and worsened voice quality during the past 15 days. Multinomial logistic regression was used to analyze factors independently associated with dysphonia in each response subgroup and in total. One third of the female teachers did not report voice symptoms during the past 15 days (33%). The prevalence of probable dysphonia was 15%, and the prevalence for possible dysphonia was 52%. Factors associated with probable dysphonia were presence of recent upper airway problems (odds ratio [OR]=5.95, 95% confidence interval [CI]=4.06-8.71), problems at work because of voice (OR=65.30, 95% CI=19.33-220.59), other activities with intense voice use (OR=1.71, 95% CI=1.08-2.71), high noise levels (OR=2.55, 95% CI=1.72-3.76), poor ventilation in the classroom (OR=2.00, 95% CI=1.24-3.22), current mental disorder (OR=3.20, 95% CI=2.18-4.70), sedentary life style (OR=1.94, 95% CI=1.21-3.09), and marriage (OR=1.70, 95% CI=1.16-2.47). Associations between probable dysphonia, poor working conditions, health-related aspects, and professional jeopardy indicate the complexity of dysphonia in female teachers and the need for collective intervention strategies.

    The term dangerous universal blood donor refers to potential agglutination of the erythrocytes of non-O recipients due to plasma of an O blood group donor, which contains high titers of anti-A and/or anti-B hemagglutinins. Thus, prior titration of anti-A and anti-B hemagglutinins is recommended to prevent transfusion reactions. The aim of this study was to estimate the frequency of dangerous universal donors in the blood bank of Belo Horizonte (Fundação Central de Imuno-Hematologia - Fundação Hemominas - Minas Gerais) by determining the titers of anti-A and anti-B hemagglutinins in O blood group donors. A total of 400 O blood group donors were randomly selected, from March 2014 to January 2015. The titers of anti-A and anti-B hemagglutinins (IgM and IgG classes) were obtained using the tube titration technique. Dangerous donors were those whose titers of anti-A or anti-B IgM were ≥128 and/or the titers of anti-A or anti-B IgG were ≥256. Donors were characterized according to gender, age and ethnicity. The hemagglutinins were characterized by specificity (anti-A and anti-B) and antibody class (IgG and IgM). Almost one-third (30.5%) of the O blood group donors were universal dangerous. The frequency among women was higher than that of men (p-value=0.019; odds ratio: 1.66; 95% confidence interval: 1.08-2.56) and among young donors (18-29 years old) it was higher than for donors between 49 and 59 years old (p-value=0.015; odds ratio: 3.05; 95% confidence interval: 1.22-7.69). There was no significant association between dangerous universal donors and ethnicity, agglutinin specificity or antibody class. Especially platelet concentrates obtained by apheresis (that contain a substantial volume of plasma), coming from dangerous universal donors should be transfused in isogroup recipients whenever possible in order to prevent the occurrence of transfusion reactions.

    The objective of this study was to examine the association between individual satisfaction with social and physical surroundings and the habit of smoking cigarettes. Data from the Health Survey of Adults from the metropolitan area of Belo Horizonte, Minas Gerais, Brazil, were used. Based on a probability sample, participants (n = 12,299) were selected among residents aged 20 years old or more. The response variable was the smoking habit and the explanatory variable of interest was the neighborhood perception. Potential confounding variables included demographic characteristics, health behaviors and other indicators of socioeconomic position. The prevalence of current smokers, former smokers and never smokers were 20.8, 14.1 and 65.1%, respectively; 74.4 and 25.5% of the participants were categorized as being more satisfied and less satisfied with the neighborhood, respectively. Compared to those who never smoked, former smokers (adjusted odds ratio = 1.40, 95% confidence interval 1.20 - 1.62) and current smokers (adjusted odds ratio = 1.17, 95% confidence interval 1.03 - 1.34) were less satisfied with the neighborhood compared to those who never smoked. The results of this study indicate there is an independent association between the smoking habit and a less satisfying neighborhood perception in the metropolitan region of Belo Horizonte, which does not depend on individual characteristics, traditionally reported as being associated with smoking.

    The scope of this paper is to present comparative data on drinking and driving behavior among drivers in Belo Horizonte in the State of Minas Gerais, in the period from 2005 to 2009, evaluating the impact of Law No. 11.705 (Prohibition), dated June 6, 2008. Data regarding prevalence of this behavior, collected at Sobriety Checkpoints (internationally used methodology) were analyzed using representative samples obtained from drivers on different public roads with intensive traffic in Belo Horizonte (2005-2009), thus permitting analysis of the impact of the new law. In 2008, the data showed a reduction of approximately 50% in the prevalence of individuals driving with any level of alcohol in the blood, when compared to 2007, after the change in legislation. This study showed that the impact caused by Law No.11.705 was marked in the sense of modifying the behavior under scrutiny. However, other control measures need to be added to the current legislation, in order to obtain a continuous reduction of drinking and driving behavior, thereby fostering a culture of sobriety on the road.

    This article evaluates government measures to reduce inequity in the health sector in Belo Horizonte from 1993 to 1997. Our hypothesis is that a municipal administration committed to equity can reduce disparities in health with the support of the Unified National Health System (SUS). The methodology used an urban quality of life index in Belo Horizonte to detect social inequalities in living conditions, as well as differences between the component indices in the infant mortality rate. Other municipal measures were assessed according to the investment resulting from the implementation of a participatory local budget and open planning process. The urban quality of life index appeared to be an appropriate measure for orienting municipal administration. The infant mortality rate proved to be a good indicator for measuring inequality in health. There was a reduction in IMR and mortality reducing gaps in the districts studied. We observed greater investment of physical and financial resources in the districts with the lowest urban quality of life index, and it can thus be stated that the municipal administration reduced the prevailing inequalities.

    Asthma is a multifactorial disease and a serious public health problem. Environmental factors and poverty are the main determinants of this disease. To describe the spatial and temporal distribution of asthma-related hospitalizations and identify the areas with the highest prevalence of and vulnerability to severe asthma in a major Brazilian city. An ecological study of hospitalizations for asthma from 2002 to 2012, in children and adolescents under 15 years of age, living in Belo Horizonte, Southeast Brazil. All events were geocoded by residence address using Hospital Information System data. The socioeconomic vulnerability of residence address was ranked using the Health Vulnerability Index. Raster surfaces were generated and time-series plots were constructed to determine spatial and time trends in the frequency of asthma-related hospitalizations, respectively. Asthma-related hospitalization rates were highest in children aged 0-4 years and in boys. There was a decreasing trend in the number of asthma-related hospitalizations across the study period. Approximately 48% of all hospitalizations were children living in health vulnerable areas. Seasonal trends showed a hospitalization peak in March, April, and May, coinciding with the post-rainy period. Our findings suggest that social and environmental factors may be determinants of disparities in severe asthma.

    Few researches in Brazil have focused on factors associated with drinking and driving. The current study presents data on the prevalence and characteristics of individuals that drive under the influence of alcohol (DUI) in nine regions of the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 1,656 drivers were interviewed, of whom 1,254 (76%) agreed to answer a structured questionnaire and submit to the breathalyzer test. The breathalyzer test was positive in 15% of these drivers. The logistic regression model predicted 1.5 times higher odds of a positive breathalyzer test in drivers over 31 years of age and 4.5 times higher in individuals that reported at least weekly alcohol consumption. In addition, drivers in the Barreiro region showed two-fold odds of a positive breathalyzer test. Focused studies with sobriety checkpoints can monitor DUI behavior, drivers' characteristics, and traffic risks, meanwhile orienting public policies to prevent drinking and driving.

    The objective of this study was to analyze factors associated with access to kidney transplants from living and cadaver donors in Belo Horizonte, Minas Gerais State, Brazil. The authors conducted a non-concurrent cohort study of patients on the waiting list for kidney transplants from 2000 to 2004 and followed until transplantation, death, exclusion, or continued presence on the line at the end of the study on December 31, 2005. The Cox model was used for competing risks. Of the 835 patients, 22.7% were transplanted. Lower risk of transplantation from living donors and cadavers was observed in patients with more time on dialysis and blood type O. Lower risk of transplantation from living donors was observed in residents in a high health risk area and in recipients with diabetes. The greatest disparity in access was observed in transplants from living donors, since there were no significant socio-demographic differences in transplants from cadaver donors. One can infer that the organ allocation system contributed to mitigating socio-demographic inequalities, and that clinical issues were more relevant in access to transplants from cadaver donors.

    One of the most important objectives of a public health service is early diagnosis of disease, which provides a better prognosis and reduction in treatment cost. We investigated the delay for diagnosis and treatment of oral cancer in a public hospital. One hundred eighty records of patients who attended for their first consultation in the department of head and neck surgery in a public hospital from Belo Horizonte-Brazil, between the period from 1 January 1999 to 31 December 2001 were analysed. The following variables were analyzed: gender, age, evolution time (ET), time elapsed from referral to hospital and first appointment (RT), time elapsed from first appointment and treatment (TT), total time elapsed from first noticing the lesion and starting treatment (TTE), sites and staging. Results for males and females were, respectively: mean age = 57.9 and 60.8 years; ET= 169.4 and 215.4 days; RT = 27.9 and 40.6 days; TT = 40.9 and 44.9 days; TTE = 207.9 and 263.8 days. No correlation was observed between age and TTE for either gender. Women presented the highest mean values for ET and TTE (p<0.01). It was concluded that public health policy should be developed to address the excessively long time lapsed between diagnosis and treatment as well as improve public health education programs to promote early oral cancer identification.

    This study aimed to assess the relationship between perception of temperature inside the bus and hypertension among 1126 collective transportation workers in metropolitan region of Belo Horizonte, Brazil. Thermal discomfort was determined based on the perception of temperature inside the bus. Hypertension was determined if participant had a medical diagnosis of this disease. Prevalence ratios (PR) for hypertension and their respective 95% confidence intervals (95% CI) were adjusted using multivariate Poisson regression analysis. The perceptions of temperature inside the bus were tolerable (26.5%), disturbs a little (28.6%), disturbs a lot (34.8%) and unbearable (10.2%). The prevalence of hypertension was 14.3%. The thermal discomfort categories of disturbs a lot (PR = 1.41; 95% CI = 1.02-1.95) and unbearable (PR = 1.75; 95% CI = 1.16-2.63) were independently related to hypertension. Thermal discomfort was associated with a higher prevalence of hypertension. This finding should be considerate in new policies for public transportation.

    To describe the characteristics of victims of powdered glass-coated (manja) kite line injuries admitted to a trauma hospital in Belo Horizonte, Brazil. Cross-sectional study of victims with powdered glass-coated kite line injuries between 2005 and 2009. Data were obtained retrospectively from medical records. Central tendency and comparison of ratios were used to characterize victims. 211 victims were admitted between 2005 and 2009, 94% of which males. The majority of cases occurred in June and July (37% e 41.7%, respectively). Mean age was 15 years, with no difference between men and women. For the group of victims as a whole, upper limbs were the most prevalent site of injury, although neck and face injuries were the main site of injury among motorcyclists and cyclists. Two deaths (0.95%) were identified, both in motorcyclists, due to injury to neck structures. Residences were concentrated in three administrative areas (East, Northeast and South-central). Although the majority of injuries recorded were not severe, fatal injuries can occur, mainly among motorcyclists. Educational and preventive measures are needed to avoid potentially fatal injuries.

    According to the Vaccine Coverage Survey, performed in 2007, the immunization coverage against hepatitis B in Belo Horizonte, for infants under one year old, was below the level proposed by the Brazilian National Program of Immunization. This vaccine was used as basis for evaluating the involvement of health professionals in the process of vaccination in two Basic Health Units (UBS, acronym in Portuguese) in the city. This study is qualitative and uses the notions of Social Representations Theory and the method of Structural Analysis of Narrative to carry out the interviews and data analysis. The results show flaws related to controlling and use of the mirror card and the parent orientation, and also the monitoring of vaccination coverage (VC) and use of VC data as input for planning health actions. It was observed that the working process in the UBS is focused on routine tasks, with low creativity of the professionals, which includes representations that maintain strong tendency to value activities focused on the health of individuals to the detriment of public health actions. In conclusion, the vaccination process fault can be overcome with a greater appreciation of everyday actions and with a much better use of local information about vaccination, and some necessary adjustments within the UBS to improve public health actions.

    ABSTRACT Objective: To estimate the smoking cessation rate and to identify possible associated factors. Methods: Individuals from the Metropolitan Region of Belo Horizonte (MG) aged 15 years or more who responded to the smoking supplement of the National Household Sample Survey were selected (n=1,297). An estimate was made of the tobacco-use cessation rate relative to the 95% confidence interval. To verify factors associated with smoking cessation, Pearson's χ2 test or Student's t test were used. Results: The general smoking cessation rate was 56.7% (95% confidence interval: 52.3-61.1), with 57.7% among men and 55.5% among women. The associated factors were higher age and income. Among the 19 individuals who had stopped smoking for less than 12 months, 52.6% had been seen by a physician or healthcare professional in the previous 12 months, and 60% of them were oriented to stop smoking, but only 1 (16.7%) had been oriented at a unit of the public national Unified Healthcare System. Conclusion: Despite high rates of smoking cessation, the methods made available by the Unified Healthcare System did not show good results. It is necessary to enhance the healthcare programs that aim to reduce the proportion of smokers in the population. Such measures can have a positive long-term influence in droping mortality and morbidity rates associated with smoking and the costs for healthcare services. PMID:24728252

    This study investigated potentially infectious waste (feces, urine, blood, body fluids) in the composition of total municipal solid waste. From August to September 2002, solid waste samples from southern Belo Horizonte, capital of the State of Minas Gerais, were collected and sent to the solid waste treatment and disposal site at BR-040 for segregation and quantification. Sharps (objects that can cause cuts or puncture wounds) made up 0.02+/-0.02% of the collected waste, while non-sharps accounted for 5.47+/-1.11%. In the sharps category, the majority were razor blades (0.01+/-0.01%), while among non-sharps the most frequent components were toilet paper (3.00+/-0.90%), diapers (2.21+/-1.08%), and sanitary napkins (0.22+/-0.12%). Household infectious waste was twice the total amount of waste (infectious + common) from healthcare units. The study was discussed in light of the health hazards and safety aspects for formal and informal waste collectors.

    To investigate the association between functional health literacy and sociodemographic factors, quality of life, self-perception of health, and perception of contexts of violence in adolescents in state schools in Belo Horizonte. This is a cross-sectional analytical observational study with a probabilistic sample of 384 adolescents between 15 and 19 years old. Data collection was carried out in schools and included self-reporting questionnaires to assess the functional health literacy, socioeconomic classification, self-perceived health, and quality of life. The reliability of internal consistency of the functional health literacy instrument was determined by calculating Cronbach's alpha coefficient. A multivariate logistic regression analysis was performed using hierarchical data entry according to the level of determination of the theoretical model established. In order to evaluate the association, a significance level of 5% was considered, while the Odds Ratio used as a measure of the magnitude of the associations. The functional health literacy instrument presented a coefficient of 0.766, indicating adequate internal consistency. More than half of teenagers presented good functional health literacy. In the final model of multivariate analysis, the variables not practicing a religion (p = 0.006; OR = 2.108); social domain of quality of life (p = 0.004; OR = 1.022); and educational domain of quality of life (p = 0.009; OR = 1.019) remained associated with functional health literacy. Not practicing a religion and the increase in the scores of social and educational domains of quality of life increased the chances of better functional health literacy.

    Tritium content in the leachate of sanitary landfills, in concentrations well above those observed in global precipitation, can be used as a tracer for the evaluation of the contamination of groundwater in piezometers of the landfills and in neighbouring tubular wells. This possibility was first investigated in Brazil for sanitary landfills in the region of Belo Horizonte City. Tritium levels together with the content of metals present in water and the measurement of soil electrical conductivity, proved to be valuable for these studies and also as a tracer for hydrodynamic studies of the surface water in the Ressaca creek.

    Samples of soil, iron ore, and airborne particulate matter (size <10 μm) were analyzed with the main goal of investigating the differentiating physicochemical properties of their ferruginous compounds. These data were used to identify whether the sources of airborne particulate matter in the metropolitan area of Belo Horizonte, Minas Gerais, Brazil, are either from natural origin, as, for instance, re-suspension of particles from soil, or due to anthropogenic activities, meaning that it would be originated from the many iron ore minings surrounding the metropolitan area. Numerical simulations were used to model the atmospheric dispersion of the airborne particulate matter emitted by iron mining located at the Iron Quadrangle geodomain, Minas Gerais. Results from these numerical simulations supported identifying the sites with the highest concentrations of airborne particulate matter in the metropolitan area. Samples of these suspended materials were collected at the selected sites by using high-volume air samplers. The physicochemical features of the solid materials were assessed by X-ray fluorescence, X-ray diffraction, magnetometry, and (57)Fe Mössbauer spectroscopy. The soil materials were found to be rich in quartz, aluminum, organic matter, and low contents of iron, mainly as low crystalline iron oxides. The samples of the iron ores, on the other hand, contain high concentration of iron, dominantly as relatively pure and crystalline hematite (α-Fe2O3). The samples of the airborne particulate matter are rich in iron, mainly as hematite, but contained also quartz, aluminum, and calcium. Mössbauer spectroscopy was used to evaluate the hyperfine structure of (57)Fe of the hematite both from the iron ore and the soil samples. The structural characteristics of the hematite of these particulate materials were further explored. The direct influence of the iron ore mining on the composition of the airborne particulate matter was clearly evidenced based on the

    Pollution caused by the electromagnetic fields (EMFs) of radio frequencies (RF) generated by the telecommunication system is one of the greatest environmental problems of the twentieth century. The purpose of this research was to verify the existence of a spatial correlation between base station (BS) clusters and cases of deaths by neoplasia in the Belo Horizonte municipality, Minas Gerais state, Brazil, from 1996 to 2006 and to measure the human exposure levels to EMF where there is a major concentration of cellular telephone transmitter antennas. A descriptive spatial analysis of the BSs and the cases of death by neoplasia identified in the municipality was performed through an ecological-epidemiological approach, using georeferencing. The database employed in the survey was composed of three data banks: 1. death by neoplasia documented by the Health Municipal Department; 2. BSs documented in ANATEL ("Agência Nacional de Telecomunicações": 'Telecommunications National Agency'); and 3. census and demographic city population data obtained from official archives provided by IBGE ("Instituto Brasileiro de Geografia e Estatística": 'Brazilian Institute of Geography and Statistics'). The results show that approximately 856 BSs were installed through December 2006. Most (39.60%) of the BSs were located in the "Centro-Sul" ('Central-Southern') region of the municipality. Between 1996 and 2006, 7191 deaths by neoplasia occurred and within an area of 500 m from the BS, the mortality rate was 34.76 per 10,000 inhabitants. Outside of this area, a decrease in the number of deaths by neoplasia occurred. The greatest accumulated incidence was 5.83 per 1000 in the Central-Southern region and the lowest incidence was 2.05 per 1000 in the Barreiro region. During the environmental monitoring, the largest accumulated electric field measured was 12.4 V/m and the smallest was 0.4 V/m. The largest density power was 40.78 μW/cm(2), and the smallest was 0.04 μW/cm(2). Copyright

    The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention.

    Three institutions worked together in order to combat early weaning in a peripheric district of Belo Horizonte (Brazil): the Department of Pediatrics of the Faculty of Medicine (Federal University of Minas Gerais), the Secretary of Health of Belo Horizonte and a Brazilian assistential institution ("LBA"). One initial survey, in 1980, documented breast-feeding practices in this community, when there were no systematized actions of incentive to human milk, at local or national levels. Two similar surveys were also conducted, in 1986 and in 1992. In each one, 152 mothers with children under two years old were randomly selected and interviewed. The results showed significant progress in the breast-feeding period in the first six years, and a stabilization between 1986 and 1992. For example: if only 39.0% of the children received human milk for six months or more in 1980, 54.3% received it in 1986 and 52.4% in 1992. In 1980, 80.6% of the children were nourished with cow's milk before three months of age, to 56.5% in 1986 and 56.3% in 1992. Prenatal influence to increase the level of breast-feeding has always been weak. Besides, a reflux was detected in the last few years with regard to the participation of the maternity hospital in the educative process.

    Canine leishmaniasis caused by Leishmania chagasi (L. infantum) is found throughout the South American continent, including Brazil, and dogs are considered to be the main reservoir host for this parasite. To support the implementation of a diagnostic protocol for surveillance of the disease in the region of Belo Horizonte (Minas Gerais, Brazil) we have compared the sensitivity and specificity of two serological tests, indirect immunofluorescent antibody test (IFAT) and direct agglutination test (DAT), with the combination of direct microscopy-culture-PCR as the gold standard, using samples obtained from 103 dogs in the city of Belo Horizonte, Minas Gerais. The currently used standard serodiagnostic test, IFAT, had a sensitivity of 100% and its specificity was 74% compared to the gold standard of the study. The sensitivity and specificity of the DAT were 100% and 91%, respectively. On the basis of this study it is recommended to change from the IFAT to DAT for the serodiagnosis of canine leishmaniasis because of the superior specificity of the test combined with its user-friendliness.

After adjusting for demographic variables, temporal variation, and source of care, there was a reduction in smoking prevalence, similar between individuals with and without private health insurance, from 2003 to 2010. During this same period the prevalence of excessive alcohol intake and sedentary lifestyle increased in both groups; with the same magnitude, there was a decrease in the prevalence of leisure-time physical activity. No changes were observed in the prevalence of blood pressure measurement, but the prevalence of cholesterol testing, mammogram, and Pap smear increased more sharply in individuals without health insurance.

    This study aims to examine the relationship between neighborhood characteristics and the functional performance of elderly people living in the Belo Horizonte metropolitan area, Minas Gerais State, Brazil. Data of a representative sample of 2,033 elderly were analyzed using quantile regression. Functional performance was measured by the number of activities of daily living (ADL) the elderly had difficulty to perform. The neighborhood characteristics evaluated were: maintenance, trust, insecurity and defective sidewalks. Functional performance was found positively associated with the characteristic defective sidewalks, whose effect increased as the number of ADL the elderly had difficulty to perform increased. The results suggest that inadequate sidewalk conditions can contribute to functional losses in elderly people, especially among those who are functionally more compromised.

    This paper analyzes the association between perinatal mortality and factors related to hospital care during labor, considering that healthcare assessment is needed in order to reduce perinatal mortality. A population-based case-control study was conducted with 118 perinatal deaths (cases) and 492 births (controls) that took place in maternity hospitals of the Brazilian Unified Health System (SUS) in Belo Horizonte, Minas Gerais, Brazil. Male sex, prematurity, diseases during pregnancy, low birth weight, newborn diseases, lack of prenatal care, lack of partograph use during labor, and less than one fetus assessment per hour during labor were significantly associated with perinatal deaths. In the multiple regression analysis, lack of partograph use during labor and type of hospital were associated with perinatal deaths. These results indicate inadequate quality of care in maternity hospitals and show that health services structure and health care process are related to perinatal mortality due to preventable causes.

    The prevalence of frailty varies greatly and has received insufficient attention in developing countries. This study aimed to identify the prevalence of frailty and associated factors among the elderly in Belo Horizonte, Minas Gerais State, Brazil. Clinical, functional, and socio-demographic factors were analyzed. An ordinal regression model was used to verify conditions associated with frailty and to determine odds ratios ( α= 0.05). Prevalence rates were 46.3% for pre-frailty was 8.7% for weakness. Pre-frail and frail elderly, respectively, showed higher and increasing odds ratios for dependency in instrumental activities of daily living; restrictions in advanced activities of daily living; use of walking aids; comorbidities; falls; depressive symptoms; lower self-efficacy in preventing falls; hospitalization; and advanced age. The study identified a high percentage of frail states associated with higher odds of adverse health conditions, especially related to disability.

    Belo Horizonte, the capital of the southeastern state of Minas Gerais, Brazil, and the fourth-largest city in the country, has the highest incidence of human visceral leishmaniasis (VL) together with a high prevalence of canine VL. The Northeast Sanitary District (NSD) of Belo Horizonte has the largest historical average of human VL cases in the metropolitan region, and is classified as a priority area for epidemiological and entomological monitoring of the disease. The objectives of the present study were to determine the seasonal variation in phlebotomine fauna and to describe the environmental situations in the NSD through characterization of peri-domiciles and application of geographical information system analysis. Entomological captures were performed every two weeks during the period July 2006 to June 2007 using HP light traps placed at 16 locations where cases of human VL had been reported in 2005. The environmental characterization of these locations was accomplished using forms and photographic images. Spatial analyses was used to determine the influence of vegetation, hydrography, altitude and pockets of poverty on the occurrence of cases of human and canine VL, and of phlebotomine vectors. A total of 633 phlebotomines belonging to the subtribes Psychodopygina and Lutzomyina were captured and, of these, 75% were identified as Nyssomyia whitmani and 11% as Lutzomyia longipalpis. The majority of the studied peri-domiciles presented inadequate hygienic conditions that would favor the development of phlebotomines. No significant correlations could be established between biogeographical aspects and either the incidence of human and canine VL or the occurrence of phlebotomines. The proximity of areas with vegetation, villages, slums and open watercourses exerted little influence on the incidence of VL. These findings reinforce the urbanization of the VL profile since the disease occurred in locations where conditions that have been classically related to its

    To determine the prevalence of overweight and obesity and to study potential risk factors for these conditions in persons over 18 years of age in the metropolitan area of Belo Horizonte, Brazil. Data were obtained from a population-based study conducted in 1996 and 1997 by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IBGE) with a random sample of 1 105 individuals. Height and weight were measured by trained personnel. Overweight (body mass index [BMI] > or = 25.0 kg/m2) and obesity (BMI > or = 30.0 kg/m2) were the dependent variables. Bivariate analysis and multivariate logistic regression were used to identify potential risk factors for overweight and obesity. The prevalence of overweight and obesity was 31.1% (95% confidence interval 195% CI]: 27.3 to 35.2) and 5.7% (95% CI: 4.0 to 8.1), respectively, in men, and 25.9% (95% CI: 22.4 to 29.8) and 14.7% (95% CI: 11.9 to 17.9), respectively, in women. Multivariate analysis revealed that age and marital status were independent risk factors for overweight, whereas age, sex, and education were independent risk factors for obesity. Being female and well-educated showed a protective effect against overweight (odds ratio [OR] = 0.52; 95% CI: 0.33 to 0.83), but not against obesity (OR = 3.01; IC 95%: 1.14 to 7.94). Women with low education had a significantly greater risk (OR = 5.95; 95%CI: 2.51 to 14.12) of developing obesity than men having a high educational level. These results suggest that overweight and obesity may be serious public health problems in the metropolitan area of Belo Horizonte, Brazil. It is important to carry out further studies in order to explore the potential relationship between overweight and obesity on the one hand, and behavioral variables, such as smoking and alcohol consumption, on the other.

    The scope of this study is to evaluate the condition of household food and nutrition (in)security (IAN) of the users of low-budget restaurants in Belo Horizonte (BH). This is an analytical cross-sectional study carried out on all low-budget restaurants and cafeteria in BH with a sample of 1613 users. The IAN was assessed using the Brazilian Food Insecurity Scale and cross-checked with the socioeconomic profile of the users. The Chisquare and Mann-Whitney tests were applied. All p-value < 0.25 variables were included in the multivariate analysis. The groups most exposed to IAN among users of low-budget restaurants are those with a lower socioeconomic level and per capita income class and those with a large number of residents in the household. Also affected are those who admit to having different kinds of wants and needs, and those for whom price and living alone are the main reasons for frequenting low-budget restaurants. The factors affecting the IAN are varied and multifactorial, thus representing a major challenge for public policy makers and for those who live directly with these dietary restrictions. The low-budget restaurants serve as a strategy for promoting healthy eating habits.

Consecutive clinical charts and neuropathological reports of 242 patients aged 61 years or older were reviewed. The patients died in Hospital das Clínicas, Federal University of Minas Gerais, in Belo Horizonte, Minas Gerais, Brazil, from 1976 to 1997. The prevalent diseases of the central nervous system (CNS) found in decreasing order were: CVDs (71.9%), infections (12.4%), neoplasms (7.1%), head trauma (3.7%), nutritional diseases (2.5%) and degenerative diseases (1.7%). The most common CVDs were cerebral atherosclerosis (61.2%), hypertensive cerebrovascular disease (25.6%) and cerebral infarct (14.9%). There was an increase in prevalence and severity of atherosclerosis and an increase in prevalence of hypertensive cerebrovascular disease with advancing age. A significant association between hypertensive cerebrovascular disease and atherosclerosis was found. The CVDs patients had clinical stroke and this was the direct cause of death in 42,7% and 17,3% of the cases, respectively. The CVDs were the most prevalent group of diseases of the CNS in elderly patients. Atherosclerosis and hypertensive cerebrovascular disease were the most common CVDs, and its prevalence increased with advancing age. Hypertensive cerebrovascular disease was significantly associated with atherosclerosis.

    A cross-sectional study was conducted among dentists in the Unified National Health System (SUS) in Belo Horizonte, Minas Gerais, Brazil, to identify factors associated with their willingness to treat HIV/AIDS patients. Questionnaires were distributed at the participant's workplace. Some 140 out of 345 selected dentists (41.0%) participated. Prevalence of willingness to treat was 55.0%. Results adjusted by multiple logistic regression showed that willingness to treat was significantly associated with a realistic perception of occupational risk (OR = 4.8; 95%CI: 1.32-18.04), knowledge of the exposure protocol (OR = 4.5; 95%CI: 1.61-13.07), positive attitudes towards dealing with the epidemic (OR = 3.2; 95%CI: 1.37-7.45), previous professional experience with HIV/AIDS patients (OR = 3.0; 95%CI: 1.30-7.19), and opposition to compulsory testing of patients for HIV (OR = 2.3; 95%CI: 0.96-5.40). Dentists with prior accidental exposure to potentially contaminated material showed less willingness to treat (OR = 0.4; 95%CI: 0.15-0.85). Fear of contamination was the main source of anxiety for health workers dealing with HIV/ AIDS patients.

    The scope of this study is to identify the factors that influence the consumer's decision when buying medicine. Prior to the Generics Act (Lei dos Genéricos), consumers had at their disposal two product purchase options in the private market, namely buying a reference drug and a similar one. Generic drugs are part of a public policy which was intended to broaden access to medication by the general population at more accessible costs, while maintaining the same quality as the reference drug, as ensured by bioequivalence tests from the national health surveillance agency ANVISA. Nevertheless, a question arises as to whether the potential consumer knows the difference between generic, similar and reference drugs, especially when taking into account the decision at the moment of purchase. In order to fulfill the proposed objective, a survey was conducted with 403 residents in Belo Horizonte, Brazil. The data gathered was tabulated and analyzed using factor analysis and crosstab. The results made it possible to infer that there is a strong predisposition among consumers to accept the suggestions of the pharmacists and/or salesman, and a significant portion of the population is confused at the moment of purchase.

    The aim of the present study was to analyze the spatial pattern of cases of maxillofacial injuries caused by interpersonal violence, based on the location of the victim’s residence, and to investigate the existence of conditions of socio-spatial vulnerability in these areas. This is a cross-sectional study, using the data of victims attended in three emergency hospitals in Belo Horizonte-Brazil between January 2008 and December 2010. Based on the process of spatial signature, the socio-spatial condition of the victims was identified according to data from census tracts. The spatial distribution trends of the addresses of victims were analyzed using Kernel maps and Ripley’s K function. Multicriteria analysis was used to analyze the territorial insertion of victims, using a combination of variables to obtain the degree of socio-spatial vulnerability. The residences of the victims were distributed in an aggregated manner in urban areas, with a confidence level of 99%. The highest densities were found in areas of unfavorable socioeconomic conditions and, to a lesser extent, areas with worse residential and neighborhood infrastructure. Spatial clusters of households formed in slums with a significant level of socio-spatial vulnerability. Explanations of the living conditions in segregated urban areas and analysis of the concentration of more vulnerable populations should be a priority in the development of public health and safety policies.

    A cross-sectional qualitative study was conducted to establish the perceptions of 77 guardians of preschool children enrolled in a Child Day Care Center in Belo Horizonte/Minas Gerais State, regarding what is a healthy diet and the difficulties faced in having a healthy diet. The instrument used was a pretested semi-structured questionnaire containing leading questions obtained in face-to-face interviews. For data analysis, the Collective Subject Discourse technique was used, which elicited data organization of a verbal nature. It was revealed that the guardians have a notion of what healthy diet is, however their answers implied inadequate eating habits. They attributed insufficient financial resources, lack of time and ingrained eating habits as being the main difficulties in having a healthy diet. These three difficulties are the reasons given by some guardians who do not believe they have a healthy diet. The conclusion drawn is that the guardians need to have a better diet, because their eating habits influence their children's eating habits. These findings revealed the need for food and nutrition education strategies to enable the guardians to recognize and have a healthy diet.

    The present study evaluates the prevalence of enteroparasitosis in the urban slums of Belo Horizonte, Brazil and the risk of transmitting enteroparasites to the family members of infected individuals. Stool samples were collected and examined at clinical laboratories near each slum. Individuals were identified and classified as positive for parasitosis (IP+), and individuals with negative stool tests were classified as negative for parasitosis (IP−) and enrolled as control patients. We collected samples from 594 patients, of which 20.2% and 79.8% were classified as IP+ and IP−, respectively. In addition, 744 family members (FIPs) effectively participated in the study by providing fecal samples. In total, 1338 participants were evaluated. Of these, 34.6% were tested positive for parasitosis. Blastocystis was the most prevalent parasite, infecting 22.4% of individuals. Among FIPs, the overall prevalence was 46.1%. Of these, 50.6% and 44.7% were classified as FIPs+ and FIPs−, respectively. These results showed that IP+ did not impact the prevalence of infection within the studied communities, not constituting index cases of specific risk behaviors, suggesting that, in fact, these communities are exposed to similar oral–fecal routes of contamination.

    The aim of the present study was to analyze the spatial pattern of cases of maxillofacial injuries caused by interpersonal violence, based on the location of the victim's residence, and to investigate the existence of conditions of socio-spatial vulnerability in these areas. This is a cross-sectional study, using the data of victims attended in three emergency hospitals in Belo Horizonte-Brazil between January 2008 and December 2010. Based on the process of spatial signature, the socio-spatial condition of the victims was identified according to data from census tracts. The spatial distribution trends of the addresses of victims were analyzed using Kernel maps and Ripley's K function. Multicriteria analysis was used to analyze the territorial insertion of victims, using a combination of variables to obtain the degree of socio-spatial vulnerability. The residences of the victims were distributed in an aggregated manner in urban areas, with a confidence level of 99%. The highest densities were found in areas of unfavorable socioeconomic conditions and, to a lesser extent, areas with worse residential and neighborhood infrastructure. Spatial clusters of households formed in slums with a significant level of socio-spatial vulnerability. Explanations of the living conditions in segregated urban areas and analysis of the concentration of more vulnerable populations should be a priority in the development of public health and safety policies.

    In Brazil, several recurring mutations in BRCA1 and BRCA2 and a TP53 mutation (R337H) have been reported in high risk breast cancer cases. We hypothesized that these recurring mutations may also be detected in the general population and ovarian cancer cases in the state of Minas Gerais. To test this notion, participants were recruited from the outpatient and the Gynecological clinic in the UFMG Medical Center in Belo Horizonte, Minas Gerais, Brazil. BRCA1 (c.68_69delAG, c.5266dupC, c.181T>G, c.4034delA, c.5123C>A), BRCA2 (c.5946delT, c.8537_8538delAG, 4936_4939delGAAA), the c.156_157insAlu* BRCA2 and the c.1010G>A *TP53 mutation were genotyped using validated techniques. Overall, 513 cancer free participants (273 men) (mean age 47.7 ± 15.1 years) and 103 ovarian cancer cases (mean age at diagnosis 58.7 ± 9.6 years) were studied. None of the participants were found to carry any of the genotyped mutations. We conclude that the recurring mutations in BRCA1, BRCA2 and TP53 cannot be detected in the general population or consecutive ovarian cancer cases in this geographical region in Brazil.

    Diabetes Mellitus is turning into one of the main public health problems in Brazil. Many factors may contribute to the low adherence to treatment. The objective of this study was to investigate the association between educational and social-economic factors and factors related to the health, the perception of disease, social support and adherence to non-pharmacological treatment of carriers of diabetes mellitus assisted in the family health program of the Health Center in Ventosa, Belo Horizonte. Data were collected in interviews with 164 diabetics who were waiting for assistance in the health center. Univariate analysis showed significant association between adhesion to the non-pharmacological treatment and low income; place of residence; knowledge about consequences; motivation with regard to the treatment; making part of a diabetics group and orientation received from the nurse and the physiotherapist. Multivariate analysis showed the variables " treatment motivation" and "part of some diabetics group", to be statistically significant as refers to the total adhesion (p <0.05). The variables "knowledge about consequences " and " place of residence--high risk area" were statistically significant as refers to the total adhesion (p < 0.06), however presenting an inverse relation.

    The radon concentration in soil gas is directly dependent on the geological characteristics of the area, such as lithology, pedology and on geochemicals, physicals and mineralogicals parameters of the soil. This paper looks for correlations between radon concentrations in soil gas and its soil permeability, 238U, 232Th and 226Ra contents in the soil groups classified by pedologies of Metropolitan Region of Belo Horizonte (RMBH), Minas Gerais, Brazil. The soil gas radon concentrations were determined by using an AlphaGUARD® monitor at about 150 measurement points. In soil samples of the same measurement points, the concentrations of 226Ra were determined by gamma spectrometry (HPGe), and 238U and 232Th by ICP-MS. The soil permeabilities were determined by using the RADON-JOK® permeameter. The mean concentrations of radon in soil gas ranged from 13.6±3.0 kBq m-3 for Litholic Neosols until 60.6±8.7 kBq m-3 for Perferric Red Latosols. The mean of 226Ra activity concentrations presented variation of 12.4±2.5 Bq kg-1 for Litholic Neosols until 50.3±13 Bq kg-1 for Perferric Red Latosols. Approximately 40% of the soils presented high permeability. The areas of different pedologies were classified by Soil Radon Index (SRI), determined by the soil gas radon concentration and permeability. Approximately 53% of the Perferric Red Latosols measurement site could be classified as "High Risk" (Swedish criteria). The preliminary results may indicate an influence of iron formations present very close to the Perferric Red Latosols in the retention of uranium minerals, and hence an increase in the concentration of radon and radium, whereas the series are in equilibrium in the environment.

    The aim of this paper is to report a brief history of control actions for Visceral Leishmaniasis (VL) from 2006 to 2010 in the Sanitary District (DS) of Venda Nova, Belo Horizonte, Minas Gerais, Brazil, focusing on the use of information systems and Geographic Information System (GIS) tools. The analyses showed that the use of an automated database allied with geoprocessing tools may favor control measures of VL, especially with regard to the evaluation of control actions carried out. Descriptive analyses of control measures allowed to evaluating that the information system and GIS tools promoted greater efficiency in making decisions and planning activities. These analyses also pointed to the necessity of new approaches to the control of VL in large urban centers.

    Because of the high prevalence of iron-deficiency anemia in Brazil, individual control measures tend to be ineffective, and fortification of foods with iron is considered the most effective method to fight anemia. To evaluate the effectiveness of fortification of drinking water with iron and vitamin C in the reduction of anemia in children in day-care centers in Belo Horizonte, Brazil. This before-and-after study evaluated 318 children aged 6 to 74 months. Identification data and data on socioeconomic variables were collected; anthropometric and biochemical measurements were performed before and after 5 months of fortification of water with 5 mg of elemental iron and 50 mg of ascorbic acid per liter. The fortified water was used for drinking and cooking at the day-care center. Wilcoxon's nonparametric test was used to evaluate the differences in continuous variables, and McNemar's test was used to compare the prevalence rates of anemia. The prevalence of anemia decreased significantly from 29.3% before fortification to 7.9% at the end of the study, with a significant increase in hemoglobin levels. Reductions in the prevalence rates of stunting and underweight were observed. Fortification of water with iron and vitamin C significantly reduced the prevalence of anemia and improved nutritional status among children attending day-care centers.

    This study analyzed leisure-time physical activity among 1,621 adults who were non-users of the Academias da Cidade Program in Belo Horizonte, Minas Gerais State, Brazil, but who lived in the vicinity of a fitness center in operation (exposed Group I) or in the vicinity of two sites reserved for future installation of centers (control Groups II and III). The dependent variable was leisure-time physical activity, and linear distance from the households to the fitness centers was the exposure variable, categorized in radial buffers: < 500m; 500-1,000m; and 1,000-1,500m. Binary logistic regression was performed with the Generalized Estimation Equations method. Residents living within < 500m of the fitness center gave better ratings to the physical environment when compared to those living in the 1,000 and 1,500m buffers and showed higher odds of leisure-time physical activity (OR = 1.16; 95%CI: 1.03-1.30), independently of socio-demographic factors; the same was not observed in the control groups (II and III). The findings suggests the program's potential for influencing physical activity in the population living closer to the fitness center and thus provide a strategic alternative for mitigating inequalities in leisure-time physical activity.

    The rehabilitation centers have emerged and become legitimized in the biomedical model, which from the implementation of attendance, namely the operational guidelines of the national policy of humanization in care and management of the Unified Health System (SUS), have been seeking changes to ensure humanized access and the resolution of health problems. The aim of this study was to analyze the attendance in Rehabilitation Centers of Reference (CCR) of SUS in Belo Horizonte (MG), from the perspectives of professionals and patients. Using a qualitative approach, the research was carried out from August 9 to December 27, 2010, in three CRRs. For data collection, focus groups were conducted with 21 professionals and interviews with 30 patients. This study showed that the current biomedical model in the view of professionals restricts its activities in attendance, limiting the participation and autonomy of patients. The attendance has led to reflections and questions when broadening the vision and governability of the teams. The results reveal the need to equip teams for the construction of innovative practices through ongoing education and the creation of protected spaces for reflection and discussion.

    In 1992, a dog naturally infected with Leishmania was found in a periurban area of Sabará, state of Minas Gerais, where human cutaneous leishmaniasis had been previously described. The parasite was classified as Leishmania, subgenus Viannia, which L. braziliensis, the main species of parasite present in the southeast Brazil, also belongs. In order to assess the importance of the dog in the transmission cycle of the disease, a canine survey was undertaken. Six hundred thirty-one dogs were examined and the prevalence of seropositive dogs for crude Leishmania amazonensis antigen was 3.2%. The presence of infected people and seropositive dogs either near or in the same house was observed. This fact suggests some transmission in the domiciliary environment, with the dogs being a risk factor for human infection in that periurban area. In the other hand, the low percentage of seropositive dogs points towards a secondary importance of these animals in the transmission of Leishmaniasis in that recent focus of the disease.

  15. Role of horizontal density advection in seasonal deepening of the mixed layer in the subtropical Southeast Pacific

    The mechanisms behind the seasonal deepening of the mixed layer (ML) in the subtropical Southeast Pacific were investigated using the monthly Argo data from 2004 to 2012. The region with a deep ML (more than 175 m) was found in the region of (22°-30°S, 105°-90°W), reaching its maximum depth (~200 m) near (27°-28°S, 100°W) in September. The relative importance of horizontal density advection in determining the maximum ML location is discussed qualitatively. Downward Ekman pumping is key to determining the eastern boundary of the deep ML region. In addition, zonal density advection by the subtropical countercurrent (STCC) in the subtropical Southwest Pacific determines its western boundary, by carrying lighter water to strengthen the stratification and form a "shallow tongue" of ML depth to block the westward extension of the deep ML in the STCC region. The temperature advection by the STCC is the main source for large heat loss from the subtropical Southwest Pacific. Finally, the combined effect of net surface heat flux and meridional density advection by the subtropical gyre determines the northern and southern boundaries of the deep ML region: the ocean heat loss at the surface gradually increases from 22?S to 35?S, while the meridional density advection by the subtropical gyre strengthens the stratification south of the maximum ML depth and weakens the stratification to the north. The freshwater flux contribution to deepening the ML during austral winter is limited. The results are useful for understanding the role of ocean dynamics in the ML formation in the subtropical Southeast Pacific.

    find seasonal horizontal crustal motions observed by GPS positioning in elastic response to heavy rainfall in the Amazon Basin and to monsoons in Southeast Asia to be consistent with those inferred from Gravity Recovery and Climate Experiment (GRACE) gravity observations of water mass loading. Solid Earth moves toward the Amazon during heavy spring rainfall and toward Southeast Asia during summer monsoons and back away from these areas 6 months later when the water load is minimum. Vertical oscillations observed by GPS and inferred from GRACE are 2 to 3 times larger than horizontal oscillation near the margins of the areas of large mass loading. Some discrepancies between GPS and GRACE are probably caused by local effects that influence GPS measurements, because the GPS sites that show significant discrepancies also do not match nearby GPS sites. However, when the load is short wavelength, the limited spatial resolution of GRACE can cause systematic misfits.

    Greater socio-environmental instability favors the individual production of knowledge because innovations are adapted to new circumstances. Furthermore, instability stimulates the horizontal transmission of knowledge because this mechanism disseminates adapted information. This study investigates the following hypothesis: Greater socio-environmental instability favors the production of knowledge (innovation) to adapt to new situations, and socio-environmental instability stimulates the horizontal transmission of knowledge, which is a mechanism that diffuses adapted information. In addition, the present study describes “how”, “when”, “from whom” and the “stimulus/context”, in which knowledge regarding medicinal plants is gained or transferred. Data were collected through semi-structured interviews from three groups that represented different levels of socio-environmental instability. Socio-environmental instability did not favor individual knowledge production or any cultural transmission modes, including vertical to horizontal, despite increasing the frequency of horizontal pathways. Vertical transmission was the most important knowledge transmission strategy in all of the groups in which mothers were the most common models (knowledge sources). Significantly, childhood was the most important learning stage, although learning also occurred throughout life. Direct teaching using language was notable as a knowledge transmission strategy. Illness was the main stimulus that triggered local learning. Learning modes about medicinal plants were influenced by the knowledge itself, particularly the dynamic uses of therapeutic resources.

    Infection with hepatitis B virus (HBV) is much more common in tropical than in temperate countries. Visitors to the tropics are thus at risk from HBV, though the degree of risk, and the routes of infection involved are uncertain. We report serological markers of HBV in two groups of 2nd World War soldiers, who served in the Thai/Burma jungles. The groups comprised 100 ex-prisoners of the Japanese (POW), and 100 Burma Campaign Veterans (BCV). Surface antigen to HBV (HbsAg) was positive in 0% of POW and 2% of BCV (P = not significant). Surface antibody (anti-HBs) and core antibody (anti-HBc) were both positive in 40% POW and 13% BCV (P less than 0.001). Quoted UK prevalence rates for these markers are 0.1% for HBsAg, 1.5% for anti-HBs and 0.7% for anti-HBc. Both groups thus show very high rates of past HBV infection. For the POW there were many possible reasons, including contaminated surgical instruments and needles, blood transfusions, and multiple beatings with common weapons. None of these factors operated significantly for BCV. Malarial transmission was, however, intense in both groups, though more so in POW. The data thus again raise the possibility of horizontal transmission of HBV by biting insects in tropical countries.

    The results of a 20-month period study in Brazil were analyzed to compare horizontal-flow constructed wetlands (CW) and waste stabilization pond (WSP) systems in terms of land area requirements and performance to produce effluent qualities for surface water discharge, and for wastewater use in agriculture and/or aquaculture. Nitrogen, E. coli and helminth eggs were more effectively removed in WSP than in CW. It is indicated that CW and WSP require similar land areas to achieve a bacteriological effluent quality suitable for unrestricted irrigation (10(3) E. coli per 100 mL), but CW would require 2.6 times more land area than ponds to achieve quite relaxed ammonia effluent discharge standards (20 mg NH(3) L(-1)), and, by far, more land than WSP to produce an effluent complying with the WHO helminth guideline for agricultural use (< or =1 egg per litre).

    The objective of this study was to perform lookback study in recipients of blood components from human T-lymphotropic virus (HTLV) seropositive donors. HTLV-1/2 may be transmitted by blood transfusion. Brazil is an endemic area for the virus and its screening in blood donors is mandatory since 1993. Hemominas Foundation (HF) is the public transfusion centre in Minas Gerais, Brazil. Data on HTLV-1/2 seropositive donors and recipients from 1993 to 2004 were obtained at HF and 24 contracting hospitals. From 1993 to 2004, HTLV-1/2 enzyme immunoassay (EIA) was performed in 918 678 donations of approximately 422 600 blood donor candidates. Of these, 456 donors (0.1%) were reactive and confirmed by Western blot (WB): 449 HTLV-1 and 7 HTLV-2. Sixty-six (14.5%) were repeat donors and had 194 blood cellular components produced from their previous donations. Of the distributed components, 119/146 (81.5%) had the recipient traced, with a total of 114 individuals. Of these, only 13 recipients were tested: six (46%) were HTLV-1 positive (four recipients of red cell units, two of platelets) and seven (54%) were negative (six of red cell units and one of platelets). Eleven did not respond and 62/114 (54.0%) were deceased. Another 28/114 (25.0%) could not be located. All six seropositive HTLV-1 recipients identified had no symptoms suggestive of HTLV-1-associated diseases. Acellular components, when used alone, were not associated with HTLV seropositivity. HTLV-1 transmission by cellular blood components occurred before screening for the virus was introduced. Haemovigilance was difficult to perform due to unavailability of computer systems before 1999 and to inadequate medical records at hospitals.

    Objective: To investigate the prevalence of oral language, orofacial motor skill and auditory processing disorders in children aged 4-10 years and verify their association with age and gender. Methods: Cross-sectional study with stratified, random sample consisting of 539 students. The evaluation consisted of three protocols: orofacial motor skill protocol, adapted from the Myofunctional Evaluation Guidelines; the Child Language Test ABFW - Phonology; and a simplified auditory processing evaluation. Descriptive and associative statistical analyses were performed using Epi Info software, release 6.04. Chi-square test was applied to compare proportion of events and analysis of variance was used to compare mean values. Significance was set at p≤0.05. Results: Of the studied subjects, 50.1% had at least one of the assessed disorders; of those, 33.6% had oral language disorder, 17.1% had orofacial motor skill impairment, and 27.3% had auditory processing disorder. There were significant associations between auditory processing skills’ impairment, oral language impairment and age, suggesting a decrease in the number of disorders with increasing age. Similarly, the variable "one or more speech, language and hearing disorders" was also associated with age. Conclusions: The prevalence of speech, language and hearing disorders in children was high, indicating the need for research and public health efforts to cope with this problem. PMID:26300524

    To evaluate the prevalence of toxoplasmosis, rubella, cytomegalovirus, hepatitis B&C and syphilis (Torchs) in a cohort pregnant women and to identify the sociodemographic, clinical and laboratory factors. A total of 1,573 HIV-infected pregnant women from a Brazilian metropolitan region were studied between 1998 and 2013. The results of serological tests were available for 704 (44.8%) pregnant women. Pregnant women were considered to be Torchs positive (Gtp) when they had positive results for at least one of these infections, and to be Torchs negative (Gtn) when they had negative results for all of them. Maternal covariables were: age, marital status, educational level, time and mode of infection, CD4 lymphocyte count, viral load at delivery, and use of antiretroviral therapy (ARV). Neonatal covariables were: HIV infection, prematurity, low birth weight, neonatal complications, abortion and neonatal death. Odds ratios with 95% confidence interval were used to quantify the association between maternal and neonatal variables and the presence of Torchs. Among 704 pregnant women, 70 (9.9%; 95%CI 7.8-12.4) had positive serological tests for any Torchs factor. The individual prevalence rates were: 1.5% (10/685) for toxoplasmosis; 1.3% (8/618) for rubella; 1.3% (8/597) for cytomegalovirus; 0.9% (6/653) for hepatitis B and 3.7% (20/545) for hepatitis C; and 3.8% (25/664) for syphilis. The HIV Vertical HIV transmission was 4.6% among Gtp pregnant women and 1.2% among Gtn women. Antiretroviral therapy (ARV), vertical transmission, low birth weight and neonatal complications were significantly associated with Torchs positivity in univariate analysis. The Torchs prevalence found in the study was high for some infections. These findings emphasize the need to promote serological Torchs screening for all pregnant women, especially HIV-infected women, so that an early diagnosis can be made and treatment interventions can be implemented to prevent vertical HIV transmission.

    Psychologists in hospital settings are part of a complex network of professional relationships in constant negotiation. In addition, psychologists have skills that enable them to work with social phenomena and to act strategically within them. This is especially important in inter-disciplinary team work where professional boundaries can generate barriers to change. This article shows how psychologists of a maternity hospital in a working-class district of a large Brazilian city adapted to an integral approach to health care in a way that helped other professionals to rethink practices.

They represent a collection sampled by Belo Monte's Programa de Salvamento do Patrimônio Paleontológico (PSPP), which includes unprecedented invertebrate fauna and fossil vertebrates from Pitinga, Jatapu, Manacapuru, Maecuru e Alter do Chão formations from Amazonas basin, Brazil. The Belo Monte paleontological salvage was able to recover 495 microfossil samples and 1744 macrofossil samples on 30 months of sampling activities, and it is still ongoing. The macrofossils identified are possible plant remains, ichnofossils, graptolites, brachiopods, molluscs, athropods, Agnatha, palynomorphs (miosphores, acritarchs, algae cysts, fungi spores and unidentified types) and unidentified fossils. However, deep scientific research is not part of the scope of the program, and this collection must be further studied by researchers who visit Museu Paraense Emilio Goeldi, where the fossils will be housed. More material will be collected until the end of the program. The collection sampled allows a mosaic composition with the necessary elements to assign, in later papers, taxonomic features which may lead to accurate species identification and palaeoenvironmental interpretations.

    Home to beautiful jungles, booming industry, and age-old temples, Southeast Asia has become a confluence of ancient and modern life. This true-color image of mainland Southeast Asia was acquired on November 30, 2001, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The body of water in the upper righthand corner of the image is the Gulf of Tonkin. East and southeast of the gulf are the dark green jungles of Vietnam, Laos, and Cambodia. The light brown Mekong River winds its way through the center of the Cambodian jungle and into southern Vietnam. The dark blue patch to the left of the river at the bottom of the image is the Tonle Sap. Literally translated to mean 'Great Lake,' the Tonle Sap is the largest freshwater lake in Southeast Asia. During the rainy season from May to October, the lake will more than double in size growing from its wintertime extent of 3,000 square kilometers to over 7,500 square kilometers. North of the lake, approximately in the center of the image, is a saucer-shaped patch of reddish brown land known as the Khorat Plateau. Situated 90 to 200 meters above sea level in eastern Thailand, the dry plateau is mostly covered with farmland and savanna-type grasses and shrubs. Moving south again, the large body of light blue water at the bottom central portion of the image is the Gulf of Thailand. By switching to the full resolution image (250 meters per pixel) and following the Gulf of Thailand to its northernmost extent, one can see a pinkish beige patch of terrain covered by a faint latticework of fine lines. These are likely to be the network of roads that crisscross Bangkok and its surrounding suburbs and fertile farmland. The narrow strip of land to the east of the Gulf of Thailand is the Malay Peninsula. The body of water to the left of the peninsula is the Gulf of Martaban, which borders Myanmar (Burma).

  9. Amesos2 and Belos: Direct and Iterative Solvers for Large Sparse Linear Systems

    2012-01-01

    Solvers for large sparse linear systems come in two categories: direct and iterative. Amesos2, a package in the Trilinos software project, provides direct methods, and Belos, another Trilinos package, provides iterative methods. Amesos2 offers a common interface to many different sparse matrix factorization codes, and can handle any implementation of sparse matrices and vectors, via an easy-to-extend C++ traits interface. It can also factor matrices whose entries have arbitrary “Scalar” type, enabling extended-precision and mixed-precision algorithms. Belos includes many different iterative methods for solving large sparse linear systems and least-squares problems. Unlike competing iterative solver libraries, Belos completely decouples themore » algorithms from the implementations of the underlying linear algebra objects. This lets Belos exploit the latest hardware without changes to the code. Belos favors algorithms that solve higher-level problems, such as multiple simultaneous linear systems and sequences of related linear systems, faster than standard algorithms. The package also supports extended-precision and mixed-precision algorithms. Together, Amesos2 and Belos form a complete suite of sparse linear solvers.« less

  12. Dams in the Amazon: Belo Monte and Brazil's Hydroelectric Development of the Xingu River Basin

    NASA Astrophysics Data System (ADS)

    Fearnside, Phillip M.

    2006-07-01

    Hydroelectric dams represent major investments and major sources of environmental and social impacts. Powerful forces surround the decision-making process on public investments in the various options for the generation and conservation of electricity. Brazil’s proposed Belo Monte Dam (formerly Kararaô) and its upstream counterpart, the Altamira Dam (better known by its former name of Babaquara) are at the center of controversies on the decision-making process for major infrastructure projects in Amazonia. The Belo Monte Dam by itself would have a small reservoir area (440 km2) and large installed capacity (11, 181.3 MW), but the Altamira/Babaquara Dam that would regulate the flow of the Xingu River (thereby increasing power generation at Belo Monte) would flood a vast area (6140 km2). The great impact of dams provides a powerful reason for Brazil to reassess its current policies that allocate large amounts of energy in the country’s national grid to subsidized aluminum smelting for export. The case of Belo Monte and the five additional dams planned upstream (including the Altamira/Babaquara Dam) indicate the need for Brazil to reform its environmental assessment and licensing system to include the impacts of multiple interdependent projects.

  16. Horizontal drilling developments

    SciTech Connect

    Gust, D.

    1997-05-01

    The advantages of horizontal drilling are discussed. Use of horizontal drilling has climbed in the past half decade as technology and familiarity offset higher costs with higher production rates and greater recoveries from new and existing wells. In essence, all types of horizontal wells expose a larger section of the reservoir to the wellbore with a resulting increase in flow rates. (A horizontal well may also be drilled to provide coning control or to intersect vertical fractures.) Thus, drilling horizontally, both onshore and offshore, reduces the number of wells necessary to develop a field.

  17. Autonomy and susceptibility to HIV/AIDS among young women living in a slum in Belo Horizonte, Brazil.

    2007-01-01

    In Brazil in the last decade there has been an increase in the susceptibility of young women to HIV. This study explored the link between autonomy, or control over major domains of economic, social and sexual life, and susceptibility to HIV infection among poor young women living in an urban slum area of Brazil. A cross-sectional survey was carried out on a random sample of 356 young women between 15 and 24 years old. The study found that indicators of autonomy that relate to sexuality, mobility and freedom from threat by partners were significantly correlated with practices linked to HIV prevention and with access to health services promoting prevention, especially among adolescents. Young women who talked to their partner about condom use before first intercourse and co-decided with them on condom use were more likely to use condoms. In contrast, those who had ever been victim of physical violence by a partner or whose partners restricted their mobility were less likely to use condoms. The study found that young women were more likely to have accessed health services for gynaecological examinations, family planning services and HIV testing if they had ever been pregnant. The findings indicate that structural gender inequalities translate into unequal relationships and reduced autonomy, increasing young women's susceptibility to HIV. A bias in HIV testing and reproductive health services towards pregnant women leaves many susceptible youth without early access. The study suggests the development of a reproductive health policy that ensures that young women access services before they get pregnant and that also reaches young males.

    The Trypanosoma comprises flagellates able to infect many mammalian species and is transmitted by several groups of invertebrates. The order Chiroptera can be infected by the subgenera Herpetosoma, Schizotrypanum, Megatrypanum and Trypanozoon. In this study, we described the diversity of bats trypanosomes, inferring the phylogenetic relationships among the trypanosomes from bats caught Belo Monte Hydroeletric area (Brazilian Amazonia). Trypanosomes from bats were isolated by haemoculture, and the molecular phylogeny based on small subunit rDNA (SSU rDNA) and glycosomal-3-phosphate dehydrogenase (gGAPDH) gene sequences. Morphological characterization included light and scanning electron microscopy. A total of 157 bats were caught in the area belonging 6 Families (Emballonuridae, Furipteridae, Mormoopidae, Natalidae, Phyllostomidae and Vespertilionidae) and 34 species. The bat trypanosome prevalence, as evaluated through haemoculture, was 5,7%. Phylogenetic trees grouped the isolates in T. cruzi branch (TCI and TCbat lineage), T. cruzi marinkellei and Trypanosoma wauwau from Pteronotus parnellii. This is the first isolate from T. wauwau in Para state. The occurrence of T. cruzi in the ​​ Belo Monte Hydroeletric area (UHE Belo Monte) in Amazon/Brazil attentive to the risk of migration human population required for the works of the dam and new cities that grow in the vicinity of these businesses, but it is a zoonosis already known to the Amazon region, and the presence of unclassified Trypanosoma species, attend to the large parasitic biodiversity still unknown.

    Aquatic ecosystems, from deep sea reefs and coastal marshes to freshwater springs and wetlands, are home to diverse assemblages of life. These commercially and ecologically important systems are part of our national heritage, and are often treasured places or refuges that protect rare or threatened species. In the water-rich Southeastern United States, managers face the challenge of understanding how water and land use affect the region's aquatic life. The Southeast Ecological Science Center (SESC) helps address that challenge by providing objective science that can be used to evaluate proposed actions and develop management strategies.

  15. Dicyclic horizontal symmetries

    NASA Astrophysics Data System (ADS)

    Kong, Otto Cho Wing

    In the very successful standard theory of particle physics, the occurrence of repeated quark and lepton flavors, and especially their peculiar mass spectrum, can be accommodated parametrically but is largely unexplained. The present dissertation is an investigation into dicyclic horizontal symmetries as a theory addressing this elusive problem of flavor, as well as some other related issues in particle physics. A horizontal symmetry is a supplement to the perspective based on the experimentally well-established standard model, and its (supersymmetric) unification theories. Dicyclic groups are a special class of discrete non- abelian groups. The most pressing part of the flavor problem in the standard model is the existence of three families of (fermionic) matter and the unnaturally large hierarchy among the parameters describing their masses and mixing. In particular, the top quark is singled out as the only fermion having a natural mass at electroweak breaking scale. While bottom and tau masses may be suppressed by the Higgs vacuum expectation value, the small masses of the other two families beg an explanation. The supersymmetric counterpart of the problem is the need for a high degree of degeneracy especially among the squarks of the lighter two families. We first analyze the phenomenologically-viable quark and squark mass matrix textures using a simple algebraic method, paying particular attention to a 2 + 1 family structure. These serve as inputs for our model building exercises. We next illustrate how the various theoretical and phenomenological constraints single out a gauged dicyclic group as the most appealing candidate for a horizontal symmetry and discuss systematically our major model building strategies. A few models obtained along this line are then presented. These include a supersymmetric SU(5) /otimes Q12 /otimes U(1) model that successfully produces a phenomenologically-viable mass matrix texture pattern for the quarks and squarks.

  16. Haemoglobinopathies in southeast Asia.

    2011-10-01

    In Southeast Asia α-thalassaemia, β-thalassaemia, haemoglobin (Hb) E and Hb Constant Spring (CS) are prevalent. The abnormal genes in different combinations lead to over 60 different thalassaemia syndromes, making Southeast Asia the locality with the most complex thalassaemia genotypes. The four major thalassaemic diseases are Hb Bart's hydrops fetalis (homozygous α-thalassaemia 1), homozygous β-thalassaemia, β-thalassaemia/Hb E and Hb H diseases. α-Thalassaemia, most often, occurs from gene deletions whereas point mutations and small deletions or insertions in the β-globin gene sequence are the major molecular defects responsible for most β-thalassaemias. Clinical manifestations of α-thalassaemia range from asymptomatic cases with normal findings to the totally lethal Hb Bart's hydrops fetalis syndrome. Homozygosity of β-thalassaemia results in a severe thalassaemic disease while the patients with compound heterozygosity, β-thalassaemia/Hb E, present variable severity of anaemia, and some can be as severe as homozygous β-thalassaemia. Concomitant inheritance of α-thalassaemia and increased production of Hb F are responsible for mild clinical phenotypes in some patients. However, there are still some unknown factors that can modulate disease severity in both α- and β-thalassaemias. Therefore, it is possible to set a strategy for prevention and control of thalassaemia, which includes population screening for heterozygotes, genetic counselling and foetal diagnosis with selective abortion of affected pregnancies.

    This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

    Reactors of the boiling water type are described wherein water serves both as the moderator and coolant. The reactor system consists essentially of a horizontal pressure vessel divided into two compartments by a weir, a thermal neutronic reactor core having vertical coolant passages and designed to use water as a moderator-coolant posltioned in one compartment, means for removing live steam from the other compartment and means for conveying feed-water and water from the steam compartment to the reactor compartment. The system further includes auxiliary apparatus to utilize the steam for driving a turbine and returning the condensate to the feed-water inlet of the reactor. The entire system is designed so that the reactor is self-regulating and has self-limiting power and self-limiting pressure features.

    Intracellular protoplasmic movements may, due to gravity, have a vertical component greater or different from the horizontal one. This makes horizontal microscopy indispensable in the search for the cellular sensor of gravity. The possibility of the latter being a cell organelle assigns special significance to high-resolution microscopy. A horizontal suction device for picking up a cell and its high-resolution horizontal microscopy in a rectangular capillary may be helpful for detection of gravity-related shifts of cellular organelles in vivo.

  11. Almost horizontal turbulence

    NASA Astrophysics Data System (ADS)

    Kolmogorov, A. N.

    2004-04-01

    The paper is published without modifications. Kolmogorov's manuscript was apparently prepared during his participation in one of expeditions of the ship "D. Mendeleev" to the Atlantic Ocean (1969) or in a circumnavigation of the world (1971) organized by the Institute for Oceanology led at the time by A.S. Monin. As Kolmogorov himself wrote, the choice of the topic was stimulated by observations concerning "...meanders with horizontal sizes of hundreds of kilometers on a flow involving a layer of hundreds of meters, with subsequent disintegration of these meanders into vortices gradually decreasing in size to several kilometers." In modern terminology, the paper is devoted to the problem of intensive mixing in pycnoclines, that is, thin layers of stratified fluid, caused by internal waves whose frequencies are less than the Brent-Väisälä frequency. Here I would like to note two circumstances. The first is the scientific insight characteristic for Kolmogorov; this very approach was later reflected in numerous publications (see, for instance, the monograph by V.S. Modevich, V.I. Nikulin, and A.G. Stetsenko "Dynamics of internal mixing in a stratified medium," Institute for Hydromechanics, Academy of Sciences of Ukraine, Naukova Dumka, Kiev 1988). The second, the more significant in my opinion, is the genuine intellectual curiosity and breadth of thought of this great thinker, who studied not only the most abstract mathematical constructions but also got his head out of the clouds with great interest to solve concrete applied problems.

  12. Inferring Horizontal Gene Transfer

    PubMed Central

    Lassalle, Florent; Dessimoz, Christophe

    2015-01-01

    Horizontal or Lateral Gene Transfer (HGT or LGT) is the transmission of portions of genomic DNA between organisms through a process decoupled from vertical inheritance. In the presence of HGT events, different fragments of the genome are the result of different evolutionary histories. This can therefore complicate the investigations of evolutionary relatedness of lineages and species. Also, as HGT can bring into genomes radically different genotypes from distant lineages, or even new genes bearing new functions, it is a major source of phenotypic innovation and a mechanism of niche adaptation. For example, of particular relevance to human health is the lateral transfer of antibiotic resistance and pathogenicity determinants, leading to the emergence of pathogenic lineages [1]. Computational identification of HGT events relies upon the investigation of sequence composition or evolutionary history of genes. Sequence composition-based ("parametric") methods search for deviations from the genomic average, whereas evolutionary history-based ("phylogenetic") approaches identify genes whose evolutionary history significantly differs from that of the host species. The evaluation and benchmarking of HGT inference methods typically rely upon simulated genomes, for which the true history is known. On real data, different methods tend to infer different HGT events, and as a result it can be difficult to ascertain all but simple and clear-cut HGT events. PMID:26020646

  13. HIV in Southeast Asia.

    PubMed

    Abrams, S

    1998-01-01

    This article explores the HIV/AIDS epidemic in Southeast Asia. Prostitution and injecting drug use are two major factors in the appearance of HIV/AIDS in a country. But, it is the correct social network that assures its transmission to epidemic proportions. Heterosexual transmission in Cambodia, Myanmar, and Thailand is linked with prevalence among female sex workers and their clients. In Malaysia, the Ministry of Health responded immediately, but the number of new infections continued to increase. The failures suggest the need for more effective, intensive health education programs, outreach by nongovernmental organizations, and peer education at the grassroots level and in remote areas. Public health officials need to promote political change. International agencies could play an important role, if countries such as Myanmar, Cambodia, and Viet Nam were open to international exchanges. In Myanmar, political unrest has a priority over the need for aggressive health interventions. In Indonesia, the Islamic influence prevents recognition of the country's significant sex industry or the existence of a homosexual community. In Cambodia, health officials warned about the high number of sexual partners, high mobility rate, and low condom use, but HIV spread rapidly in the 1990s. Thailand initiated a 100% condom campaign to combat HIV prevalence in the 1990s, and HIV prevalence declined among sex workers and military recruits. Risk factors for rapid transmission include mobility, the number of sexual partners/sex worker, the proportion engaging in commercial sex, and the rate of regular condom use among sex workers.

    Peak daily pumpage from the highly permeable, unconfined Biscayne aquifer for public water-supply systems in southeast Florida in 1975 was about 500 million gallons. Another 165 million gallons was withdrawn daily for irrigation. Recharge to the aquifer is primarily by local rainfall. Discharge is by evapotranspiration, canal drainage, coastal seepage, and pumping. Pollutants can enter the aquifer by direct infiltration from land surface or controlled canals, septic-tank and other drainfields, drainage wells, and solid-waste dumps. Most of the pollutants are concentrated in the upper 20 to 30 feet of the aquifer; public supply wells generally range in depth from about 75 to 150 feet. Dilution, dispersion, and adsorption tend to reduce the concentrations. Seasonal heavy rainfall and canal discharge accelerate ground-water circulation, thereby tending to dilute and flush upper zones of the aquifer. The ultimate fate of pollutants in the aquifer is the ocean, although some may be adsorbed by the aquifer materials en route to the ocean, and some are diverted to pumping wells. (Woodard-USGS)

  16. Present-day stress field of Southeast Asia

    It is now well established that ridge push forces provide a major control on the plate-scale stress field in most of the Earth's tectonic plates. However, the Sunda plate that comprises much of Southeast Asia is one of only two plates not bounded by a major spreading centre and thus provides an opportunity to evaluate other forces that control the intraplate stress field. The Cenozoic tectonic evolution of the Sunda plate is usually considered to be controlled by escape tectonics associated with India-Eurasia collision. However, the Sunda plate is bounded by a poorly understood and complex range of convergent and strike-slip zones and little is known about the effect of these other plate boundaries on the intraplate stress field in the region. We compile the first extensive stress dataset for Southeast Asia, containing 275 A-D quality (177 A-C) horizontal stress orientations, consisting of 72 stress indicators from earthquakes (located mostly on the periphery of the plate), 202 stress indicators from breakouts and drilling-induced fractures and one hydraulic fracture test within 14 provinces in the plate interior. This data reveals that a variable stress pattern exists throughout Southeast Asia that is largely inconsistent with the Sunda plate's approximately ESE absolute motion direction. The present-day maximum horizontal stress in Thailand, Vietnam and the Malay Basin is predominately north-south, consistent with the radiating stress patterns arising from the eastern Himalayan syntaxis. However, the present-day maximum horizontal stress is primarily oriented NW-SE in Borneo, a direction that may reflect plate-boundary forces or topographic stresses exerted by the central Borneo highlands. Furthermore, the South and Central Sumatra Basins exhibit a NE-SW maximum horizontal stress direction that is perpendicular to the Indo-Australian subduction front. Hence, the plate-scale stress field in Southeast Asia appears to be controlled by a combination of Himalayan

    The Xingu River, one of the major tributary of the Amazon River, was recently impounded by the Belo Monte dam, a massive and controversial hydropower plant that will become the third biggest power station in generating capacity of the world. Given the limited data associated with greenhouse gas emissions from reservoirs in the Amazon basin, the impacts of hydroelectric expansion in this region to the global carbon budget remains unclear. Here, we used a bottom-up assessment to quantify a fraction of the possible emissions associated with the Belo Monte reservoir. Eighteen soil samples were collected before the impoundment from seven different locations and depths in areas that were going to be permanently flooded by the reservoir (forests and pasturelands). Soil samples were split in triplicates and incubated in anoxic conditions during two phases totaling 160 days of anoxic incubation in order to quantify the potential methane and carbon dioxide production through time. Our results showed that pasturelands soil presented higher potential production of both gases in relation to the soils from forested areas, reaching up to 0.072 mg CH4 g-¹d-1 and 0.078 mg CO2 g-¹d-1 during the first period of 65 days in the first phase of incubations. Significant differences in production were also noted through soil depth and time. In several areas, the first 15 cm of soil generated 99% of the methane volume that was being produced in the 60 cm sampled profile. The first 65 days of the second phase of incubations showed production that was 35% (CH4) and 44% (CO2) lower than the same period in the first stage. Extrapolations towards the total flooded area demonstrates that 27.3-43.3 ton CH4 d-1 may be generated from flooded soils in the Belo Monte reservoir during only the first several months of flooding, maintaining significant production rates during upcoming months as long as favorable conditions are maintained.

    BACKGROUND Patch testing is an efficient method to identify the allergen responsible for allergic contact dermatitis. OBJECTIVE To evaluate the results of patch tests in children and adolescents comparing these two age groups' results. METHODS Cross-sectional study to assess patch test results of 125 children and adolescents aged 1-19 years, with suspected allergic contact dermatitis, in a dermatology clinic in Brazil. Two Brazilian standardized series were used. RESULTS Seventy four (59.2%) patients had "at least one positive reaction" to the patch test. Among these positive tests, 77.0% were deemed relevant. The most frequent allergens were nickel (36.8%), thimerosal (18.4%), tosylamide formaldehyde resin (6.8%), neomycin (6.4%), cobalt (4.0%) and fragrance mix I (4.0%). The most frequent positive tests came from adolescents (p=0.0014) and females (p=0.0002). There was no relevant statistical difference concerning contact sensitizations among patients with or without atopic history. However, there were significant differences regarding sensitization to nickel (p=0.029) and thimerosal (p=0.042) between the two age groups under study, while adolescents were the most affected. CONCLUSION Nickel and fragrances were the only positive (and relevant) allergens in children. Nickel and tosylamide formaldehyde resin were the most frequent and relevant allergens among adolescents.

    The objective was to determine the prevalence of upper-limb and back pain among dentists (n = 358) and factors associated with these symptoms. Dentists were interviewed using a self-administered questionnaire containing data on sociodemographic, occupational, lifestyle, and psychosocial factors and presence, site, and characteristics of pain. Participation rate was 92.3%. 58% reported upper limb pain, with 22, 21, 20, and 17% for the arm, back, neck, and shoulder, respectively. 26% reported daily frequency and 40% classified pain as moderate or severe. In the multivariate analysis (multiple logistic regression), the factors associated with pain were: neck: anxiety/depression (OR = 2.3; CI95%: 1.2-4.5), compressor in the office (OR = 2.1; CI95%: 1.2-3.7), job satisfaction (OR = 0.3; CI95%: 0.1-0.9), and use of indirect vision (OR = 0.5; CI95%: 0.3-0.9); shoulder: income > 20 minimum wage (OR = 2.9; CI95%: 1.2-6.7), greater productivity (OR = 3.3; CI95%: 1.3-8.4), height > or = 160cm (OR = 0.3; CI95%: 0.2-0.7), and age 30-49 years (OR = 0.3; CI95%: 0.1-0.8); back: anxiety/depression (OR = 2.3; CI95%: 1.2-4.5), manual activity (OR = 0.4; CI95%: 0.2-0.9), and being married (OR = 0.5; CI95%: 0.3-0.9); arms: manual activity (OR = 1.8; CI95%: 1.0-3.2).

    Hypertriglyceridemia incidence should be estimated in HIV-infected patients after antiretroviral therapy (ART) initiation. We retrospectively analyzed clinical data of HIV-infected adults at 3 public referral centers. Cumulative and person-time incidences were estimated for patients without hypertriglyceridemia. Survival time and hazard ratio (HR) were estimated by Kaplan-Meier analysis and Cox proportional regression, respectively. Cumulative and person-time incidences were 40.4% and 1.4 cases/100 person-months, respectively. The median period for hypertriglyceridemia occurrence was 47 months. Men and patients with switched ART regimens had increased hypertriglyceridemia risk (HR=3.05 and 3.34, respectively). Hypertriglyceridemia incidence is high in HIV-infected patients undergoing ART.

Compliance rates before and after the implementation were compared. After the implementation of a mobile health aplication, compliance with the nursing care plan increased from 53% to 94%. The system reduced IT spending, increased the nursing team efficiency and prevented planned hiring. The use of a mobile health solution with geolocating feature by a nursing home care team increased compliance to the care plan.

    The scope of this article is to evaluate the nutritional status, body composition and tumor characteristics of 31 patients with breast cancer attended at the Mastology Service of Hospital das Clínicas of the Federal University of Minas Gerais. Dietary data were obtained from the 24-hour dietary recall in the pre-operative state and analyzed by the DietWin Professional 2008 Nutrition Software. Body composition was assessed by bioelectrical impedance analysis. The tumor characterization data were collected from medical records. The mean age of patients was 50.75 ± 14.34 years. Excess body weight was found in 58% and waist circumference greater than 80 cm in 64.5% of patients Excessive consumption of oils and sugars was observed in 90.3% and 83.8%, respectively. Most had low intakes of calcium and vitamins B6, B12 and A. The predominant diagnosis was type II histological grade invasive ductal carcinoma in stage II or III. The prevalence of overweight and inadequate dietary intake demonstrate the need for individualized nutritional guidance and monitoring to improve the prognosis and quality of the life of patients.

    Patch testing is an efficient method to identify the allergen responsible for allergic contact dermatitis. To evaluate the results of patch tests in children and adolescents comparing these two age groups' results. Cross-sectional study to assess patch test results of 125 children and adolescents aged 1-19 years, with suspected allergic contact dermatitis, in a dermatology clinic in Brazil. Two Brazilian standardized series were used. Seventy four (59.2%) patients had "at least one positive reaction" to the patch test. Among these positive tests, 77.0% were deemed relevant. The most frequent allergens were nickel (36.8%), thimerosal (18.4%), tosylamide formaldehyde resin (6.8%), neomycin (6.4%), cobalt (4.0%) and fragrance mix I (4.0%). The most frequent positive tests came from adolescents (p=0.0014) and females (p=0.0002). There was no relevant statistical difference concerning contact sensitizations among patients with or without atopic history. However, there were significant differences regarding sensitization to nickel (p=0.029) and thimerosal (p=0.042) between the two age groups under study, while adolescents were the most affected. Nickel and fragrances were the only positive (and relevant) allergens in children. Nickel and tosylamide formaldehyde resin were the most frequent and relevant allergens among adolescents.

    The present work was aimed at proposing a control measure for Rhipicephalus sanguineus in a naturally infected kennel of 72 m(2) of the UFMG Veterinary School with 25 dogs of different breeds. A sensitivity test to acaricide products was applied in a sample of R. sanguineus. Out of the acaricide products tested: 12.5% Amitraz (product 1); 2% Alfamethrin and 60% Dichlorvos association (product 2); 5% Deltamethrin (product 3) and the association between 77.6% Trichlorfon, 1.0% Coumaphos and 1.0% Cyfluthrin (product 4); only 1 and 4 products showed 100% efficacy. Amitraz (12.5%) was used for controlling R. sanguineus in the surrounding of the kennel, on which four treatments every seven days were carried out in the facilities. For parasitic R. sanguineus, a single topical treatment was used: Flumetrin 1.0% pour-on on all the 25 dogs. This control measure significantly reduced the population of R. sanguineus within the kennel. A slight infestation was observed in the seventh month after treatment. A new application of 12.5% Amitraz was done in the kennel as well as a new topical treatment with Flumetrin 1.0% pour-on on the dogs. The control procedure proposed in the present study was an emergency measure and its effectiveness was checked through environmental surveys throughout a one-year period.

    The Nuclear Technology Development Centre/Brazilian Commission for Nuclear Energy, CDTN/CNEN, is the only Brazilian Institution to apply the k0-standardisation method of instrumental neutron activation technique determining elements using its own nuclear reactor, TRIGA MARK I IPR-R1. After changes in the reactor core configuration, the reactor neutron flux distribution in typical irradiation channels had to be updated, as well as the parameters f and α, needed to apply the k0-method of neutron activation analysis. The neutron flux distribution in the rotary rack was evaluated through the specific count rate of 198Au and the parameters f and α, were determined in five selected channels applying the "Cd-ratio for multi-monitor" method, using a set of Al-(0.1%)Au and Zr (99.8%) monitors. Several reference materials were analysed, indicating the effectiveness of the improved method.

The linearity of these lakes suggests that they could have, in the past, belonged to the same drainage system, that would have been disconnected throughout the evolution of the Vereda system. The objective of this research is with the help of the GPR and using 100 MHz antennaes to obtain radargram images that could assist in the interpretation of the structures occurring at the bottom of these lakes. It is possible do identify on the radargrams reflectors that can be correlated with depositional system. These reflectore have the concave form. The results of these radargrames indicate great conformity between the concave form of the sediments and that of the bottom of the lake, allowing to assume that this deposition has been occurring since a long time ago. Therefore, if there was a connection between the study lake and those located in its proximity it has occurred a long time, before the deposition of the sedimentary sequences had been deposited. The thickness of the sediments, that varies since 2m until 5m, indicates that or either this deposition was either a very rapid one so that could generate a fast deposition, or it has been taking place during a considerable geologic long time.; Data acquisitiont;

    2016-01-01

    In this article, I describe a study exploring horizontal violence and nurses’ perceptions of the phenomenon within the context of two 28-bed inpatient hospital units. The purpose of the study was to develop a clearer understanding of horizontal violence, incorporating observation and inquiry to identify the language nurses use to describe their experiences and factors in the nursing work environment that may perpetuate the phenomenon. Observation, review and analysis of policies, and interviews with staff were completed between June and November 2012. Thematic analysis resulted in five themes: (a) behaviors are minimized and not recognized, (b) fear inhibits all reporting, (c) avoidance and isolation are coping strategies, (d) lack of respect and support, and (e) organizational chaos. The findings suggest future interventions must address a range of factors that perpetuate horizontal violence within the nursing work environment with consideration for the embeddedness and complexity of the phenomenon.

    Snyder, Glenn J.

    1988-01-01

    A nuclear component horizontal seismic restraint. Small gaps limit horizontal displacement of components during a seismic occurrence and therefore reduce dynamic loadings on the free lower end. The reactor vessel and reactor guard vessel use thicker section roll-forged rings welded between the vessel straight shell sections and the bottom hemispherical head sections. The inside of the reactor guard vessel ring forging contains local vertical dovetail slots and upper ledge pockets to mount and retain field fitted and installed blocks. As an option, the horizontal displacement of the reactor vessel core support cone can be limited by including shop fitted/installed local blocks in opposing alignment with the reactor vessel forged ring. Beams embedded in the wall of the reactor building protrude into apertures in the thermal insulation shell adjacent the reactor guard vessel ring and have motion limit blocks attached thereto to provide to a predetermined clearance between the blocks and reactor guard vessel ring.

    Atmospheric aberrations reduce the resolution and contrast in surveillance images recorded over horizontal or slant paths. This paper describes our recent horizontal and slant path imaging experiments of extended scenes as well as the results obtained using speckle imaging. The experiments were performed with an 8-inch diameter telescope placed on either a rooftop or hillside and cover ranges of interest from 0.5 km up to 10 km. The scenery includes resolution targets, people, vehicles, and other structures. The improvement in image quality using speckle imaging is dramatic in many cases, and depends significantly upon the atmospheric conditions. We quantify resolution improvement through modulation transfer function measurement comparisons.

    The results of canonical theory for the evolution of horizontal-branch (HB) stars are examined. Particular attention is given to how an HB star maintains the appropriate composition distribution within the semiconvective zone and how this composition is affected by the finite time-dependence with which convective boundaries actually move. Newly developed models based on time-dependent overshooting are presented for both the core-helium-exhaustion and main HB phases.

    An international survey of horizontal environmental wells was performed during May and June of 1993. The purpose of the survey was to provide the environmental industry with an inventory of horizontal environmental wells and information pertaining to the extent of the use of horizontal environmental wells, the variety of horizontal environmental well applications, the types of geologic and hydrogeologic conditions within which horizontal environmental wells have been installed, and the companies that perform horizontal environmental well installations. Other information, such as the cost of horizontal environmental well installations and the results of tests performed on the wells, is not complete but is provided as general information with the caveat that the information should not be used to compare drilling companies. The result of the survey is a catalogue of horizontal environmental wells that are categorized by the objective or use of the wells, the vertical depth of the wells, and the drilling company contracted to install the wells.

    The magmatic activity (0–16 Ma) in Iceland is linked to a deep mantle plume that has been active for the past 62 My. Icelandic and northeast Atlantic basalts contain variable proportions of two enriched components, interpreted as recycled oceanic crust supplied by the plume, and subcontinental lithospheric mantle derived from the nearby continental margins. A restricted area in southeast Iceland—and especially the Öræfajökull volcano—is characterized by a unique enriched-mantle component (EM2-like) with elevated 87Sr/86Sr and 207Pb/204Pb. Here, we demonstrate through modeling of Sr–Nd–Pb abundances and isotope ratios that the primitive Öræfajökull melts could have assimilated 2–6% of underlying continental crust before differentiating to more evolved melts. From inversion of gravity anomaly data (crustal thickness), analysis of regional magnetic data, and plate reconstructions, we propose that continental crust beneath southeast Iceland is part of ∼350-km-long and 70-km-wide extension of the Jan Mayen Microcontinent (JMM). The extended JMM was marginal to East Greenland but detached in the Early Eocene (between 52 and 47 Mya); by the Oligocene (27 Mya), all parts of the JMM permanently became part of the Eurasian plate following a westward ridge jump in the direction of the Iceland plume.

    Mayon volcano is the most active volcano in the Philippines, located just north of the coastal town of Legaspi in southern Luzon about 325 km southeast of Manila. Mayon is a near-perfect cone; its steep, forested slopes look rather like a bull's eye when viewed from above. For scale, Mayon's circular footprint is about 16 km in diameter. This photograph was taken from the Space Shuttle on April 8, 1997. At the time the photo was taken, Mayon sported a steam plume from the summit. The lighter (non-forested) regions that radiate from the summit to the southern slopes are flows from eruptions that have occurred over the past twenty-five years. The current eruption, which started June 24, 2001, is sending flows down the southeast slope in the general direction of Legaspi. Image STS083-747-88 was provided by the by the Earth Sciences and Image Analysis Laboratory, Johnson Space Center.

  14. Panspermia and horizontal gene transfer

    NASA Astrophysics Data System (ADS)

    Klyce, Brig

    2009-08-01

    Evidence that extremophiles are hardy and ubiquitous is helping to make panspermia a respectable theory. But even if life on Earth originally came from space, biologists assume that the subsequent evolution of life is still governed by the darwinian paradigm. In this review we show how panspermia could amend darwinism and point to a cosmic source for, not only extremophiles but, all of life. This version of panspermia can be called "strong panspermia." To support this theory we will discuss recent evidence pertaining to horizontal gene transfer, viruses, genes apparently older than the Earthly evolution of the features they encode, and primate-specific genes without identifiable precursors.

    Nosenko, Tetyana; Bhattacharya, Debashish

    2007-01-01

    Background Horizontal gene transfer (HGT), the non-genealogical transfer of genetic material between different organisms, is considered a potentially important mechanism of genome evolution in eukaryotes. Using phylogenomic analyses of expressed sequence tag (EST) data generated from a clonal cell line of a free living dinoflagellate alga Karenia brevis, we investigated the impact of HGT on genome evolution in unicellular chromalveolate protists. Results We identified 16 proteins that have originated in chromalveolates through ancient HGTs before the divergence of the genera Karenia and Karlodinium and one protein that was derived through a more recent HGT. Detailed analysis of the phylogeny and distribution of identified proteins demonstrates that eight have resulted from independent HGTs in several eukaryotic lineages. Conclusion Recurring intra- and interdomain gene exchange provides an important source of genetic novelty not only in parasitic taxa as previously demonstrated but as we show here, also in free-living protists. Investigating the tempo and mode of evolution of horizontally transferred genes in protists will therefore advance our understanding of mechanisms of adaptation in eukaryotes. PMID:17894863

    ISS01-E-5316 (23 January 2001) -- Popocatépetl, or Popo, the active volcano located about 70 kilometers southeast of Mexico City, sends a plume south on January 23, 2001. The Expedition One crew onboard the International Space Station (ISS) observed and recorded this image with a digital still camera as it orbited to the northeast of the volcano. Popo has been frequently active for six years. On this day, the eruption plume reportedly rose to more than 9 kilometers above sea level (for reference, Popo's summit elevation is 5426 meters). Note the smaller ash plume below the main plume. The perspective from the ISS allowed the crew members this unique three dimensional view. Popo is situated between two large population centers: Mexico City (more than 18 million people, and just out of this image at right) and Puebla (about 1.2 million people), partially visible at lower left.

    In 2014, the U.S. Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) is assessing stream quality across the Piedmont and southern Appalachian Mountains in the southeastern United States. The goal of the Southeast Stream Quality Assessment (SESQA) is to characterize multiple water-quality factors that are stressors to aquatic life—contaminants, nutrients, sediment, and streamflow alteration—and the relation of these stressors to ecological conditions in streams throughout the region. Findings will provide communities and policymakers with information on which human and environmental factors are the most critical in controlling stream quality and, thus, provide insights about possible approaches to protect or improve stream quality. The SESQA study will be the second regional study by the NAWQA program, and it will be of similar design and scope as the Midwest Stream Quality Assessment conducted in 2013 (Van Metre and others, 2012).

  3. Fake artesunate in southeast Asia.

    Artesunate is a key antimalarial drug in the treatment of multidrug-resistant Plasmodium falciparum malaria in southeast Asia. We investigated the distribution of counterfeit artesunate tablets by use of the validated, simple, and inexpensive Fast Red TR dye technique. We also aimed to identify distinguishing characteristics of the fake drugs. Of 104 shop-bought "artesunate" samples from Cambodia, Laos, Myanmar (Burma), Thailand, and Vietnam, 38% did not contain artesunate. Characteristics such as cost and physical appearance of the tablets and packaging reliably predicted authenticity. The illicit trade in counterfeit antimalarials is a great threat to the lives of patients with malaria. The dye test will assist national malaria control authorities in urgently needed campaigns to stop this murderous trade.

  4. Structure and agency in development-induced forced migration: the case of Brazil’s Belo Monte Dam

    PubMed Central

    2017-01-01

    This paper examines how structure and agency interact to shape forced migration outcomes. Specifically, I ask how structural factors such as compensation policies as well as social, financial, and human capital may either foster or constrain migration aspirations and capabilities. I use longitudinal, semi-structured interview data to study forced migration among farmers displaced by the Belo Monte Dam in the Brazilian Amazon. Results from baseline interviews indicate that nearly all community members aspired to purchase rural land in the region and maintain livelihoods as cacao farmers or cattle ranchers. Constraints limiting the ability to attain aspirations included strict requirements on land titles for properties, delays in receiving compensation, rising land prices, and the lack of power to negotiate for better compensation. Despite these constraints, most migrants succeeded in attaining aspirations, as they were able to mobilize resources such as social networks, financial capital, skills, and knowledge. These findings highlight the importance of considering the relationship between structure and agency within forced migration research. I conclude by discussing how the findings may inform resettlement policies for future cases of development- or environment-induced forced migration. PMID:28298745

    Horizon-T is an innovative detector system constructed to study Extensive Air Showers (EAS) in the energy range above 1016 eV coming from a wide range of zenith angles (0°-85°). The system is located at the Tien Shan High-altitude Science Station of the Lebedev Physical Institute of the Russian Academy of Sciences at ˜ 3340 meters above sea level. It consists of eight charged particle detection points separated by distances up to one kilometer as well as an optical detector subsystem to measure the Vavilov-Cherenkov light from the EAS. The time resolution of charged particles and Vavilov-Cherenkov light photons passage of the detector system is a few ns. This level of resolution allows conducting a research of the atmospheric development of individual EAS. This report focuses on a general description of the detector system and the individual sub-systems providing an overview of the operations and latest results.

  6. Starting earthquakes under horizontal action

    The vector case of the static problem for semi-infinite lithospheric plates with rectilinear boundaries parallel to each other in two states is considered. In the first case, the distance between the plate ends is different from zero; in the second case, it is zero although the plates do not interact with each other. It is assumed that the horizontal actions on the plates (which, as is well known, move very slowly) are so strong that the vertical components of contact stresses can be neglected. In this work, it is shown that, even in this case, contact stresses at the edges of approaching plates acquire singular concentrations capable of leading to starting earthquakes. It has been shown that the theoretical calculation of the consequences of such earthquakes on the Earth's surface yields a coincidence with their real consequences.

    Phylogenic evidence suggests that the strain of Zika virus causing an unprecedented outbreak of disease in the Americas had its origin in Southeast Asia, where reports of isolated cases of Zika virus infection have occurred since 2010. Why there has been no large outbreak of Zika infection in Southeast Asia remains unclear and whether such an outbreak will occur in the future is a question of significant concern. This review looks at Zika virus from a Southeast Asian perspective and highlights some of the possible scenarios with regards to Zika virus in this part of the world as well as highlighting some of the research questions that need to be urgently addressed.

    This chapter highlights the cholera situation in South Asia and the Bay of Bengal region, the original 'homeland' of cholera. A detailed discussion of cholera outbreaks in individual countries in South-East Asia follows. The countries of the World Health Organization (WHO) SEARO (South-East Asia Region) region are discussed first, followed by discussions about the other countries in South-East Asia that do not fall within the purview of the WHO SEARO classification of the member countries of the region. Therefore, the chapter attempts to provide a comprehensive yet precise outline of the major cholera outbreaks that have occurred in the region over the years.

    The descent image motion estimation system (DIMES) is a system of hardware and software, designed for original use in estimating the horizontal velocity of a spacecraft descending toward a landing on Mars. The estimated horizontal velocity is used in generating rocket-firing commands to reduce the horizontal velocity as part of an overall control scheme to minimize the landing impact. DIMES can also be used for estimating the horizontal velocity of a remotely controlled or autonomous aircraft for purposes of navigation and control.

    2006-05-01

    The development of the asymmetry between horizontal and vertical eye tracking was investigated longitudinally at 5, 7, and 9 months of age. The target moved either on a 2D circular trajectory or on a vertical or horizontal 1D sinusoidal trajectory. Saccades, smooth pursuit, and head movements were measured. Vertical tracking was found to be inferior to horizontal tracking at all age levels. The results also show that the mechanisms responsible for horizontal and vertical tracking mutually influence one another in the production of 2D visual pursuit. Learning effects were observed within-trials but no transfer between trials was found.

    A common phenomenon in South-East Asia is ageing of the population. This article describes the various stages of development of psychogeriatrics in Hong Kong, Singapore, Malaysia, Thailand, Indonesia and the Philippines. It is only in the last few years that more systematic development of psychogeriatric services has begun under the pressure of an ageing population. The model of service delivery in Hong Kong can serve as an example of development of psychogeriatric services in South-East Asia.

    In 2002, the drug problem in Southeast and Southwest Asia was serious, particularly in the production of opium and heroin in Afghanistan, Myanmar, and Laos, the three largest producers of illicit opium in the world. The increasing illicit manufacture of ATS, particularly methamphetamine, in Southeast Asia, mainly in China and Myanmar, was also a major concern. Some reports indicated that ephedrine, used for illicitly producing methamphetamine in Southeast Asia, is diverted and smuggled out of China and India, whereas caffeine, the adulterant used for producing methamphetamine tablets, is mainly smuggled into Myanmar through its border with Thailand. Seizure data showed a dramatic increase in trafficking in MDMA through Southeast Asia. In terms of the drug epidemic, in 2002, cannabis remained overall the main drug of abuse in all of the countries of Southeast and Southwest Asia. Opiates, mainly opium and heroin, were also the drugs of choice except in Thailand, where opiate abuse declined, but ATS was the main drug of abuse due to its low cost and availability. A significant increase in ATS abuse, amphetamine, methamphetamine, and MDMA among the youth who smoked, sniffed, and inhaled them was reported in Cambodia, China, Indonesia, Laos, Myanmar, the Philippines, and Thailand. Injecting drug use among opiate abusers has been identified as the prime cause of the rapid spread of HIV/AIDS in Southeast and Southwest Asia.

    The history of horizontal glottectomy (HG) for the treatment of bilateral vocal cord lesions is not entirely clear. The present investigation analyzes the history of HG on the basis of cross-referenced database searches in general and professional medical literature databases. Books, original historical articles and medical history reviews were evaluated. The initial work was done by Moser in years from 1959 to 1965, and in 1961 he published the first paper on HG. Follow-up publications were reported in 1977 by Gramowski and in 1984 by Wilke. In 1970, Romanian laryngologists headed by Calaraşu described a HG via excision of a rhomboid-shaped portion of the thyroid cartilage, but the authors had neither sufficient numbers of patients nor a sufficiently long follow-up for the procedure to gain widespread acceptance. In 1978, Calearo and Teatini described HG similar to Calaraşu's method, but slightly more extended by the eventual inclusion of an arytenoid cartilage in the operative specimen. Theses authors have often been credited as the originators of the procedure, but actually were the first to publish in an English language journal. The procedure, while quite effective for treatment of bilateral and anterior commissure lesions, has never gained general acceptance in the United States, and in current practice, has been supplanted by endoscopic and non-surgical treatments.

    In higher organisms such as vertebrates, it is generally believed that lateral transfer of genetic information does not readily occur, with the exception of retroviral infection. However, horizontal transfer (HT) of protein coding repetitive elements is the simplest way to explain the patchy distribution of BovB, a long interspersed element (LINE) about 3.2 kb long, that has been found in ruminants, marsupials, squamates, monotremes, and African mammals. BovB sequences are a major component of some of these genomes. Here we show that HT of BovB is significantly more widespread than believed, and we demonstrate the existence of two plausible arthropod vectors, specifically reptile ticks. A phylogenetic tree built from BovB sequences from species in all of these groups does not conform to expected evolutionary relationships of the species, and our analysis indicates that at least nine HT events are required to explain the observed topology. Our results provide compelling evidence for HT of genetic material that has transformed vertebrate genomes. PMID:23277587

  17. On the Hydraulics of Flowing Horizontal Wells

    NASA Astrophysics Data System (ADS)

    Bian, A.; Zhan, H.

    2003-12-01

    A flowing horizontal well is a special type of horizontal well that does not have pumping/injecting facility. The discharge rate of a flowing horizontal well is controlled by the hydraulic gradient between the aquifer and the well and it generally varies with time if the hydraulic head of the aquifer is transient. This type of well has been used in landslide control, mining dewatering, water table control, underground water transportation through a horizontal tunnel, agricultural water drainage, and other applications. Flowing horizontal wells have quite different hydrodynamic characteristics from horizontal wells with fixed pumping or injecting rates because their discharge rates are functions of the aquifer hydraulic heads (Zhan et al, 2001; Zhan and Zlotnik, 2002). Hydraulics of flowing horizontal wells have rarely been studied although the hydraulics of flowing vertical wells have been extensively investigated before. The purpose of this paper is to obtain analytical solutions of groundwater flow to a flowing horizontal-well in a confined aquifer, in a water table aquifer without precipitation, and in a water table aquifer with precipitation. The functions of the flowing horizontal well discharge rates versus time will be obtained under above mentioned different aquifer conditions. The relationships of the aquifer hydraulic heads versus the discharge rates of the well will be investigated. The rate of water table decline due to the dewatering of the well will also be computed, and this solution is particularly useful for landslide control and mining dewatering. The theoretical solutions will be compared with results of experiments that will be conducted in the hydrological laboratory at Texas A&M University.

    The Xingu River, one of the most important of the Amazon Basin, is characterized by clear and transparent waters that drain a 509.685 km2 watershed with distinct hydrological and ecological conditions and anthropogenic pressures along its course. As in other basins of the Amazon system, studies in the Xingu are scarce. Furthermore, the eminent construction of the Belo Monte for hydropower production, which will alter the environmental conditions in the basin in its lower middle portion, denotes high importance of studies that generate relevant information that may subsidize a more balanced and equitable development in the Amazon region. Thus, the aim of this study was to analyze the water quality in the Xingu River and its tributaries focusing on spatial patterns by the use of multivariate statistical techniques, identifying which water quality parameters were more important for the environmental changes in the watershed. Data sampling were carried out during two complete hydrological cycles in twenty-five sampling stations. The data of twenty seven variables were analyzed by Spearman's correlation coefficients, cluster analysis (CA), and principal component analysis (PCA). The results showed a high auto-correlation between variables (> 0.7). These variables were removed from multivariate analyzes because they provided redundant information about the environment. The CA resulted in the formation of six clusters, which were clearly observed in the PCA and were characterized by different water quality. The statistical results allowed to identify a high spatial variation in the water quality, which were related to specific features of the environment, different uses, influences of anthropogenic activities and geochemical characteristics of the drained basins. It was also demonstrated that most of the sampling stations in the Xingu River basin showed good water quality, due to the absence of local impacts and high power of depuration of the river itself.

    Rayleigh wave data have been used extensively to produce various SV-wave tomographic models of the upper mantle. Love wave data are more difficult to deal with resulting in fewer SH-wave tomographic models. The models also do not incorporate higher mode information which can place better constraints on the model. We have assembled a large, horizontal component data set and have inverted these seismogram in the 4-13 mHz band including higher mode information. We use a version of the automated waveform inversion technique modified for Love waves. We have explored the effects of various crustal models and because of the greater sensitivity of Love waves to the crustal structure, at present, we limit our inversion to this lower frequency band. Due to the higher mode Love waves having similar group velocities between the periods of 50-100 s for oceanic paths, interference occurs which partition techniques have difficulties dealing with. The modified technique used here does not require partitioning the data and can help extract the data more easily at these period bands. We present a new VSH and Xi model for the upper mantle. High VSH extending to about 250 km depth occurs beneath the cratons and Tibet; Low VSH occurs beneath the mid-ocean ridges, the back arc basins and beneath the Afar hotspot. The Xi model shows that VSH is greater by approximately 3% at 100km and rapidly drops to zero at around 300 km depth where the mantle becomes isotropic. At 250 km depth, there are regions where SV is greater than SH, suggesting more vertical flow beneath mid-ocean ridges at these depths.

    Mediterranean region is considered to be the most prominent climate response Hot-Spot since it is located in a transition zone between the arid climate of northern Africa and the wet climate of central Europe. Even a minor change in large scale climatic factors might impose large impacts on the climatic conditions of different Mediterranean areas. Furthermore, the complex topography and the vast coastlines suggest a fine scale spatial variability of the climatic conditions. Because of these, there is an increasing interest for this area. The objective of this study is to estimate the changes in climatic parameters (such as temperature and precipitation) over southeast Europe in the near future at a very fine grid resolution. The NASA GISS GCM ModelE is used to simulate current and future climate at a horizontal resolution of 2° × 2.5° latitude by longitude. The model accounts for both the seasonal and the diurnal solar cycles in its temperature calculations. It simulates the emissions, transport, chemical transformation and deposition of several chemical tracers. Sea surface temperatures (SST) are calculated using model-derived surface energy fluxes and specified ocean heat transports. The simulations cover the period from 1880 to 2061. Greenhouse gas concentrations up to 2008 are prescribed using ice-core measurements, while for the period 2009-2061 the GHG levels are supplied from the IPCC A1B emissions scenario. Since the outputs from the GCM are relatively coarse for applications to regional and local scales, the Weather Research and Forecasting (WRF version 3.4.1) model is used to dynamically downscale GCM simulations. The domain covers the south - southeast Europe in 273 x 161 horizontal grids of 9 km x 9 km, with 28 vertical layers. Because of the time needed for the downscaling procedure meteorological conditions are presented, here, for five current (i.e., 2008 - 2012) and five future (i.e., 2058-2062) years. Annual temperature is estimated to be higher

    The Tyrrhenian Sea is a young extensional basin in the Central Mediterranean that formed within a complex convergent boundary between Africa and Eurasian Plates. Its opening, associated to the west dipping subduction of the Ionian lithosphere, started about 11 My ago and was marked first by an EW and successively by an ESE directed extension. This last mainly affected the Southeast Tyrrhenian Sea and led to the formation of the Marsili ocean-like basin. This large-scale extension produced the onset of volcanism throughout the Tyrrhenian Sea and the formation of several seamounts. High values of heat flow (>150 mW m-2) and the thin crust (7 km on average) and lithosphere (30 km on average) testify the young age of formation of oceanic crust in the Southeast Tyrrhenian Sea. On November 2007, a multidisciplinary oceanographic survey was carried out in the Southeast Tyrrhenian Sea by a group of researchers of the IAMC-CNR (Naples), Osservatorio Vesuviano (INGV, Naples), NOAA (Seattle) and GNS (New Zealand) on board of the R/V Urania. The main aim of the survey was the identification and the exploration of potential active volcanic and/or hydrothermal vents on the seamounts located in the Southeast Tyrrhenian Sea. Twelve Tyrrhenian seamounts have been explored with a modified CTD system, in order to acquire "tow-yo" profiles in dynamic mode (real time monitoring of physical and chemical parameters of seawater along vertical/horizontal profiles). In addiction, Multibeam swath bathymetry was carried out over fifteen seamounts. The strategy for the achieving of the aim consisted in two phases: i) row multibeam acquisition of the sea floor morphology to verify, confirm or review all available data, ii) tow-yo activity and seawater sampling. Here, we show the main results of bathymetric data acquisition carried out over fifteen seamounts with the use of the Reson Seabat 8160 multibeam sonar system mounted on keel of the R/V Urania.

    The Southeast Asian region had been subjected to a drastic reduction in air quality from the biomass burnings that occurred in 2013 and 2015. The smoke from the biomass burnings covered the entire region including Brunei, Indonesia, Malaysia, Singapore and Thailand, with haze particulate matter (PM) reducing the air quality to hazardous levels. Here we report a comprehensive size-composition-morphology characterization of the PM collected from an urban site in Singapore during the two haze events. The two haze events were a result of biomass burning and occurred in two different geographical source regions. We show the similarities and variations of particle size distribution during hazy and clear days during the two haze events. Sub-micron particles (<1 μm) dominate (˜50%) the aerosols in the atmosphere during clear and hazy days. Using electron microscopy, we also categorize the PM, namely soot, organic-inorganic clusters and hybrid particles. The composition and morphology were similar in both the haze events. The majority of the PM is composed of carbon (˜51%) and other elements pertaining to the earth’s crust. The complexity of the mixing state of the PM is highlighted and the role of the capture mode is addressed. We also present the morphological characterization of all the classified PM. The box counting method is used to determine the fractal dimensions of the PM, and the dimensionality varied for every classification from 1.79 to 1.88. We also report the complexities of particles and inconsistencies in the existing approaches to understand them.

    The Southeast Regional Carbon Sequestration Partnership's (SECARB) Phase I program focused on promoting the development of a framework and infrastructure necessary for the validation and commercial deployment of carbon sequestration technologies. The SECARB program, and its subsequent phases, directly support the Global Climate Change Initiative's goal of reducing greenhouse gas intensity by 18 percent by the year 2012. Work during the project's two-year period was conducted within a ''Task Responsibility Matrix''. The SECARB team was successful in accomplishing its tasks to define the geographic boundaries of the region; characterize the region; identify and address issues for technology deployment; develop public involvement and education mechanisms; identify the most promising capture, sequestration, and transport options; and prepare action plans for implementation and technology validation activity. Milestones accomplished during Phase I of the project are listed below: (1) Completed preliminary identification of geographic boundaries for the study (FY04, Quarter 1); (2) Completed initial inventory of major sources and sinks for the region (FY04, Quarter 2); (3) Completed initial development of plans for GIS (FY04, Quarter 3); (4) Completed preliminary action plan and assessment for overcoming public perception issues (FY04, Quarter 4); (5) Assessed safety, regulatory and permitting issues (FY05, Quarter 1); (6) Finalized inventory of major sources/sinks and refined GIS algorithms (FY05, Quarter 2); (7) Refined public involvement and education mechanisms in support of technology development options (FY05, Quarter 3); and (8) Identified the most promising capture, sequestration and transport options and prepared action plans (FY05, Quarter 4).

    The Archaean Southern São Francisco craton (Quadrilátero Ferrífero, Brazil) is a typical dome-and-keel province characterized by kilometer-scale gneiss-granitic domes surrounded by elongated keels of folded supracrustal rocks. The tectonomagmatic evolution of the three largest domes in the craton (namely the Bação, Bonfim and Belo Horizonte domes) occurred between 3200 and 2700 Ma. The domes expose several phases of TTG gneisses and plutons intruded by leucogranite sheets, pegmatitic dykes and bodies of calc-alkaline ("potassic") granodiorite and granite. LA-ICP-MS zircon U-Pb data allow three main periods of magmatism to be defined. These are described as the Santa Barbara (SB), Rio das Velhas I (RVI) and Rio das Velhas II (RVII) events (Lana et al., 2013). The oldest discernable evolution of the craton began at 3200 Ma (SB event) with the formation of TTG gneisses that are poorly preserved in the exposed record. This event is also attested by the occurrence of inherited zircons in younger TTGs as well as by the fact that zircons with a ca. 3200 Ma age represent a significant subset in the detrital zircon population of the greenstone belt succession. This evidence suggests that the Palaeoarchaean TTG crust has been reworked as well as eroded during tectonic denudation. The following magmatic event (RVI), which generated most of the TTG crust of the Southern São Francisco craton, took place between 2930-2870 Ma. Gneisses formed during this event have geochemical features similar to the middle-pressure TTG group defined by Moyen (2010) suggesting that they formed in equilibrium with a garnet-rich, plagioclase-poor amphibole-bearing residuum. These TTGs have K2O/Na2O between 0.3 and 0.7, Sr content between 250-500 ppm and Sr/Y lower than 150. Finally, the RVII event occurred between 2780-2700 Ma producing both TTG-like) and potassic (calc-alkaline) granitoids. In particular, calc-alkaline granitoids, distributed over an area of ˜25,000 km2, were emplaced

    This paper describes new theoretical results for predicting the buckling behavior of pipe in horizontal holes. Pipe buckling in horizontal holes occurs initially in a sinusoidal mode along the low side of the hole; at higher axial compression a helix is formed. Equations are given for computing the forces required to initiate these different buckling modes. Simple experimental laboratory results confirm the theory. Results presented in this paper apply to friction modeling of buckled tubulars to help predict when pipe can be forced to move along a long section of a horizontal well.

    The turbulent effect from the Earth's atmosphere degrades the performance of an optical imaging system. Many studies have been conducted in the study of beam propagation in a turbulent medium. Horizontal beam propagation and correction presents many challenges when compared to vertical due to the far harsher turbulent conditions and increased complexity it induces. We investigate the collection of beam propagation data, analysis, and use for building a mathematical model of the horizontal turbulent path and the plans for an adaptive optical system to use this information to correct for horizontal path atmospheric turbulence.

    Horizontal fields generated by return strokes play an important role in the interaction of lightning generated electric fields with power lines. In many of the recent investigations on the interaction of lightning electromagnetic fields with power lines, the horizontal field was calculated by employing the expression for the tilt of the electric field of a plane wave propagating over finitely conducting earth. The method is suitable for calculating horizontal fields generated by return strokes at distances as close as 200m. At these close ranges, the use of the wavetilt expression can cause large errors.

    During the summer monsoon period in south-east Asia marine airstreams normally prevail at the south China coast. However, when tropical cyclones approach then polluted airmasses from south-eastern China can impart high ionic concentrations and high acidity to rainwater. This is illustrated by two examples and the small-scale horizontal variations in rainwater composition are minor during these episodes. Since long-term quality-assured studies of the composition of rainwater in south-east Asia are scarce, the results at three sampling sites in Hong Kong during summer monsoon periods are compared with previous data from the same season. The results for the mid- to end-1990's show a similar trend to those for the ambient concentrations of sulphate and nitrate in aerosol in Hong Kong, which show flattened trends from 1995 to 1999. A marked increase in acidity is found in the summer monsoon period of 2004 which is attributed to the greater proportion of approaching cyclone weather systems in the dataset, reflecting both the increased local emission sources and the burgeoning economic growth of the Pearl River Delta Region. Comparison of the rainwater composition with that at other south-east Asian cities during the summer monsoon period shows that it is most acidic in Hong Kong.

  10. Migrant workers spreading HIV in Southeast Asia.

    1996-10-21

    Interruption of the spread of human immunodeficiency virus (HIV) across southeast Asian borders by legal and illegal migrant laborers is a major concern of the Association of Southeast Asian Nations (ASEAN). ASEAN intends to move immediately to implement regional projects focused on education, information sharing, and improved surveillance. HIV transmission from laborers from poorer countries in search of jobs in economically booming regions underscores the global nature of the AIDS problem. Malaysia, for example, has over 1 million illegal workers. Moreover, many legal guest workers who enter Malaysia with letters from a physician stating they are not HIV-infected have falsified documents.

    Horizontal steam generators are typical components of nuclear power plants with pressure water reactor type VVER. Thermal-hydraulic behavior of horizontal steam generators is very different from the vertical U-tube steam generator, which has been extensively studied for several years. To contribute to the understanding of the horizontal steam generator thermal-hydraulics a computer program for 3-D steady state analysis of the PGV-1000 steam generator has been developed. By means of this computer program, a detailed thermal-hydraulic and thermodynamic study of the horizontal steam generator PGV-1000 has been carried out and a set of important steam generator characteristics has been obtained. The 3-D distribution of the void fraction and 3-D level profile as functions of load and secondary side pressure have been investigated and secondary side volumes and masses as functions of load and pressure have been evaluated. Some of the interesting results of calculations are presented in the paper.

  13. Productivity and injectivity of horizontal wells

    One of the key issues addressed was pressure drop in long horizontal wells and its influence on well performance. Very little information is available in the literature on flow in pipes with influx through pipe walls. Virtually all of this work has been in small diameter pipes and with single-phase flow. In order to address this problem new experimental data on flow in horizontal and near horizontal wells have been obtained. Experiments were conducted at an industrial facility on typical 6 1/8 ID, 100 feet long horizontal well model. The new data along with available information in the literature have been used to develop new correlations and mechanistic models. Thus it is now possible to predict, within reasonable accuracy, the effect of influx through the well on pressure drop in the well.

    To evaluate the incidence of fungi in the ocular conjunctiva of sugar-cane cutting workers as well in a sugar-cane plantation environment. Monte Belo - MG, Eye Clinic, Laboratory of Physiology and Biology of Microorganisms of Unifenas, Alfenas - MG. Swabs were made from the ocular conjunctiva of one hundred workers of both sexes and material was collected from leaves, stalk, and the environmental air from the sugar-cane plantation. These were inoculated in specific mold media. After incubation at 25 degrees C for a period of fifteen days, the plates were analyzed and colony forming units (ufc) were identified using conventional mycological techniques. Of one hundred workers involved in this research, 64 presented one or more genera of fungi, 54 (84.38%) being identified in males and 10 (15.62%) identified in females. The separation of the workers by age range showed that the prevalence of observed fungi by age was not uniform. The highest incidences were found in advanced age ranges, the increase of positivity by age being considered statistically significant (p<0.05). The lowest prevalence (50%) was found in the 11-20-year-old interval, which presents the lowest number of examined persons. The highest positivity was verified in the 61-79 year interval. In 60 workers (93.75%) only one genus was isolated; in 3 (4.69%) two genera, and in only one worker (1.56%) three genera were isolated. The most prevalent isolated fungi were Fusarium sp (43.76%) and Geotrichum sp (23.44%), followed by Cladosporium sp (9.38%), Penicillium sp (7.81%), Mucor sp (9.38%) and Oidium sp (7.81%). The most common genus founded in leaves, stalk and air were Aspergillus, Penicillium, Fusarium, Cladosporium and Rhizopus. The environmental conditions, the socioeconomic status and the general and personal poor hygienic conditions, together with lack of information about prophylactic standards, surely led to the high incidence of ocular conjunctiva fungus isolation (67%). The incidence was much

    1994-02-21

    Cutting a window at 85[degree] deviation allowed a sidetrack to pass through the high-resistivity sections in a Gulf of Mexico reservoir. Results from logging-while-drilling (LWD) tools indicated the original horizontal bore dropped too low in the reservoir, possibly leading to a low productivity well. The subsequent sidetrack successfully delivered the desired well bore, and the increased productivity justified the efforts in cutting a window in the horizontal section.

  10. Emotion recognition (sometimes) depends on horizontal orientations

    PubMed Central

    Huynh, Carol M; Balas, Benjamin

    2014-01-01

    Face recognition depends critically on horizontal orientations (Goffaux & Dakin, 2010). Face images that lack horizontal features are harder to recognize than those that have that information preserved. Presently, we asked if facial emotional recognition also exhibits this dependency by asking observers to categorize orientation-filtered happy and sad expressions. Furthermore, we aimed to dissociate image-based orientation energy from object-based orientation by rotating images 90-degrees in the picture-plane. In our first experiment, we showed that the perception of emotional expression does depend on horizontal orientations and that object-based orientation constrained performance more than image-based orientation. In Experiment 2 we showed that mouth openness (i.e. open versus closed-mouths) also influenced the emotion-dependent reliance on horizontal information. Lastly, we describe a simple computational analysis that demonstrates that the impact of mouth openness was not predicted by variation in the distribution of orientation energy across horizontal and vertical orientation bands. Overall, our results suggest that emotion recognition does largely depend on horizontal information defined relative to the face, but that this bias is modulated by multiple factors that introduce variation in appearance across and within distinct emotions.

    Block, Timothy; Ball, Kia; Fournier, Ashley

    2014-01-21

    In 2010 the Southeast Energy Efficiency Alliance (SEEA) received a $20 million Energy Efficiency and Conservation Block Grant (EECBG) under the U.S. Department of Energy’s Better Building Neighborhood Program (BBNP). This grant, funded by the American Recovery and Reinvestment Act, also included sub-grantees in 13 communities across the Southeast, known as the Southeast Consortium. The objective of this project was to establish a framework for energy efficiency retrofit programs to create models for replication across the Southeast and beyond. To achieve this goal, SEEA and its project partners focused on establishing infrastructure to develop and sustain the energy efficiency market in specific localities across the southeast. Activities included implementing minimum training standards and credentials for marketplace suppliers, educating and engaging homeowners on the benefits of energy efficiency through strategic marketing and outreach and addressing real or perceived financial barriers to investments in whole-home energy efficiency through a variety of financing mechanisms. The anticipated outcome of these activities would be best practice models for program design, marketing, financing, data collection and evaluation as well as increased market demand for energy efficiency retrofits and products. The Southeast Consortium’s programmatic impacts along with the impacts of the other BBNP grantees would further the progress towards the overall goal of energy efficiency market transformation. As the primary grantee SEEA served as the overall program administrator and provided common resources to the 13 Southeast Consortium sub-grantees including contracted services for contractor training, quality assurance testing, data collection, reporting and compliance. Sub-grantee programs were located in cities across eight states including Alabama, Florida, Georgia, Louisiana, North Carolina, South Carolina, Tennessee, Virginia and the U.S. Virgin Islands.

    SciTech Connect

    Thomas, D.D.

    1982-08-31

    A horizontal retorting apparatus and method are disclosed designed to pyrolyze tar sands and oil shale, which are often found together in naturally occurring deposits. The retort is based on a horizontal retorting tube defining a horizontal retort zone having an upstream and a downstream end. Inlet means are provided for introducing the combined tar sands and oil shale into the upstream end of the retort. A screw conveyor horizontally conveys tar sands and oil shale from the upstream end of the retort zone to the downstream end of the retort zone while simultaneously mixing the tar sands and oil shale to insure full release of product gases. A firebox defining a heating zone surrounds the horizontal retort is provided for heating the tar sands and oil shale to pyrolysis temperatures. Spent shale and tar sands residue are passed horizontally beneath the retort tube with any carbonaceous residue thereon being combusted to provide a portion of the heat necessary for pyrolysis. Hot waste solids resulting from combustion of spent shale and tar sands residue are also passed horizontally beneath the retort tube whereby residual heat is radiated upward to provide a portion of the pyrolysis heat. Hot gas inlet holes are provided in the retort tube so that a portion of the hot gases produced in the heating zone are passed into the retort zone for contacting and directly heating the tar sands and oil shale. Auxiliary heating means are provided to supplement the heat generated from spent shale and tar sands residue combustion in order to insure adequate pyrolysis of the raw materials with varying residual carbonaceous material.

  20. Measurements of Biogenic and Anthropogenic Ozone and Aerosol Precursors during the SENEX (Southeast Nexus) Campaign 2013

    2013-12-01

    Natural emissions of ozone and aerosol precursor gases such as isoprene and monoterpenes are the highest in the southeast of the U.S. and rival those found in tropical forests. In addition, anthropogenic emissions are significant in the Southeast and photochemistry is rapid. The southeast U.S. has not warmed like other parts of the U.S. in response to global climate change, and the temperature anomaly has been suggested to be related to aerosols derived from a combination of anthropogenic and biogenic precursors. The NOAA SENEX aircraft campaign took place in June-July 2013 in the southeast U.S. as part of the Southeast Atmosphere Study (SAS). The NOAA WP-3 aircraft conducted 20 research flights between May 27 and July 10, 2013 based out of Smyrna, TN. To investigate the combination of anthropogenic and biogenic emissions several flights were designed to follow the emissions of cities and power plants as they are transported over forested regions in the Southeast. For example, over-flights of Atlanta, Birmingham and Nashville were performed and the plumes were followed to the forested areas with high isoprene and monoterpene emissions. The same was done for several power plants such as EC Gaston, Scherer and Johnsonville. In the anthropogenic plumes, effects such as the modulation of the isoprene chemistry by high NOx and particle formation and growth were investigated. The same strategy was used for three nighttime flights over Atlanta, Birmingham and the New Madrid and White Bluff power plants. Flights over and downwind of St Lois and Indianapolis were used as a contrast in areas with smaller biogenic emissions. Other anthropogenic emissions sources that were investigated during SENEX included bio refineries, paper mills, coalmines, poultry and pork farming. Also biomass burning emissions were observed during one daytime and one nighttime flight. Another focus of the SENEX campaign was to determine the emissions of natural gas and oil production from the

  1. How to drill horizontal sections faster

    SciTech Connect

    Chaffin, M. )

    1991-12-01

    This paper reports that fewer trips, reduced slide time and lower drag during sliding have resulted from the application of downhole-adjustable stabilizers to horizontal drilling. Faster drilling times mean lower measurement while drilling (MWD) cost, and less wear on downhole equipment, motors and bits. These advantages combined with reduced drilling shocks have increased drilling rates and efficiency. Applying existing technology in new situations is an important way of reducing the cost of finding, exploring for and developing reserves. Engineers are responsible for using current technology to its fullest and developing new technology to reduce drilling expenses. Horizontal drilling was used in its early stages to develop the Austin chalk formation in Pearsall oil field more effectively. As procedures were generated to drill horizontal wells, Oryx drilling engineers began to develop new technology and investigate ways for existing technology to be used or altered to fit horizontal drilling programs. The new technology of downhole-adjustable stabilizers has been used successfully to further improve horizontal drilling efficiency.

    Whole-body impulsive rotations were used to overcome several limitations associated with manual head impulse testing. A computer-controlled rotational chair delivered brief, whole-body, earth-vertical axis yaw impulsive rotations while eye movements were measured using video-oculography. Results from an unselected group of 20 patients with dizziness and a group of 22 control subjects indicated that the horizontal computerized rotational head impulse test (crHIT) is well-tolerated and provides an estimate of unidirectional vestibulo-ocular reflex gain comparable to results from caloric testing. This study demonstrates that the horizontal crHIT is a new assessment tool that overcomes many of the limitations of manual head impulse testing and provides a reliable laboratory-based measure of unilateral horizontal semicircular canal function.

    1990-06-18

    By design, the electric submersible pump (ESP) is an effective method of lifting fluids from horizontal wells. But this ESP application does have unique installation and operating parameters that need to be considered. ESP's have been used for many years in directional wells. This application provides an experience base for understanding deflection limits on the unit. To avoid damaging the ESP, special equipment may be required in some horizontal installations. This paper discusses how several ESP's have been designed specifically for medium-radius wells. In these applications, the deeper pump setting provides for a significant increase in production rate. In general, to realize the full benefit of a horizontal installation, the ESP should be considered when planning, drilling, and completing the well.

    NASA Astrophysics Data System (ADS)

    Haines, Donald A.

    1982-06-01

    Observational evidence from nine crown fires suggests that horizontal roll vortices are a major mechanism in crown-fire spread. Post-burn aerial photography indicates that unburned tree-crown streets are common with crown fire. Investigation of the understory of these crown streets after two fires showed uncharred tree trunks along a center line. This evidence supports a hypothesis of vortex action causing strong downward motion of air along the streets. Additionally, photographs of two ongoing crown fires show apparent horizontal roll vortices. Discussion also includes laboratory and numerical studies in fluid dynamics that may apply to crown fires.

  7. Petroleum systems, resources of Southeast Asia, Australasia

    Howes, J.

    1997-12-15

    The Southeast Asia-Australasia region has over 100 productive petroleum systems ranging in age from the Paleozoic to the Pliocene. Plate tectonics have played a fundamental role in controlling the distribution and character of the region`s petroleum systems. There is a clear division between those systems on the Eurasian plate and those on the Indo-Australian plate. The distribution of significant oil and gas resources is highly concentrated in just a few chrono-stratigraphic units. Early Tertiary Paleogene source rocks account for over 50% of the region`s in-place petroleum resources. This article summarizes the region`s systems and resources, and compares and contrasts some of their essential elements in Southeast Asia and Australasia. With average production of 3.2 million b/d of oil and 18 bscfd of gas, the region accounts for almost 6% of world oil and gas production.

    The occurrence of high concentrations of arsenic in the groundwater of the Southeast Asia region has received much attention in the past decade. This study presents an overview of the arsenic contamination problems in Vietnam, Cambodia, Lao People's Democratic Republic and Thailand. Most groundwater used as a source of drinking water in rural areas has been found to be contaminated with arsenic exceeding the WHO drinking water guideline of 10 μg·L(-1). With the exception of Thailand, groundwater was found to be contaminated with naturally occurring arsenic in the region. Interestingly, high arsenic concentrations (> 10 μg·L(-1)) were generally found in the floodplain areas located along the Mekong River. The source of elevated arsenic concentrations in groundwater is thought to be the release of arsenic from river sediments under highly reducing conditions. In Thailand, arsenic has never been found naturally in groundwater, but originates from tin mining activities. More than 10 million residents in Southeast Asia are estimated to be at risk from consuming arsenic-contaminated groundwater. In Southeast Asia, groundwater has been found to be a significant source of daily inorganic arsenic intake in humans. A positive correlation between groundwater arsenic concentration and arsenic concentration in human hair has been observed in Cambodia and Vietnam. A substantial knowledge gap exists between the epidemiology of arsenicosis and its impact on human health. More collaborative studies particularly on the scope of public health and its epidemiology are needed to conduct to fulfill the knowledge gaps of As as well as to enhance the operational responses to As issue in Southeast Asian countries.

    A complete horizontal molecular orientation of a linear-shaped thermally activated delayed fluorescent guest emitter 2,6-bis(4-(10Hphenoxazin-10-yl)phenyl)benzo[1,2-d:5,4-d'] bis(oxazole) (cis-BOX2) was obtained in a glassy host matrix by vapor deposition. The orientational order of cis-BOX2 depended on the combination of deposition temperature and the type of host matrix. Complete horizontal orientation was obtained when a thin film with cis-BOX2 doped in a 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP) host matrix was fabricated at 200 K. The ultimate orientation of guest molecules originates from not only the kinetic relaxation but also the kinetic stability of the deposited guest molecules on the film surface during film growth. Utilizing the ultimate orientation, a highly efficient organic light-emitting diode with the external quantum efficiency of 33.4 ± 2.0% was realized. The thermal stability of the horizontal orientation of cis-BOX2 was governed by the glass transition temperature (Tg) of the CBP host matrix; the horizontal orientation was stable unless the film was annealed above Tg.

  4. Detecting Highways of Horizontal Gene Transfer

    NASA Astrophysics Data System (ADS)

    Bansal, Mukul S.; Gogarten, J. Peter; Shamir, Ron

    In a horizontal gene transfer (HGT) event a gene is transferred between two species that do not share an ancestor-descendant relationship. Typically, no more than a few genes are horizontally transferred between any two species. However, several studies identified pairs of species between which many different genes were horizontally transferred. Such a pair is said to be linked by a highway of gene sharing. We present a method for inferring such highways. Our method is based on the fact that the evolutionary histories of horizontally transferred genes disagree with the corresponding species phylogeny. Specifically, given a set of gene trees and a trusted rooted species tree, each gene tree is first decomposed into its constituent quartet trees and the quartets that are inconsistent with the species tree are identified. Our method finds a pair of species such that a highway between them explains the largest (normalized) fraction of inconsistent quartets. For a problem on n species, our method requires O(n 4) time, which is optimal with respect to the quartets input size. An application of our method to a dataset of 1128 genes from 11 cyanobacterial species, as well as to simulated datasets, illustrates the efficacy of our method.

    2006-01-01

    The majority of well-documented cases of horizontal transfer between higher eukaryotes involve the movement of transposable elements between animals. Surprisingly, although plant genomes often contain vast numbers of these mobile genetic elements, no evidence of horizontal transfer of a nuclear-encoded transposon between plant species has been detected to date. The most mutagenic known plant transposable element system is the Mutator system in maize. Mu-like elements (MULEs) are widespread among plants, and previous analysis has suggested that the distribution of various subgroups of MULEs is patchy, consistent with horizontal transfer. We have sequenced portions of MULE transposons from a number of species of the genus Setaria and compared them to each other and to publicly available databases. A subset of these elements is remarkably similar to a small family of MULEs in rice. A comparison of noncoding and synonymous sequences revealed that the observed similarity is not due to selection at the amino acid level. Given the amount of time separating Setaria and rice, the degree of similarity between these elements excludes the possibility of simple vertical transmission of this class of MULEs. This is the first well-documented example of horizontal transfer of any nuclear-encoded genes between higher plants. PMID:16336045

    Beginning in the spring of 1994, studies of Wayne field located on the northeastern flank of the Williston Basin were initiated to determine the feasibility of using horizontal drilling to increase recoverable reserves in the field. The Wayne subinterval is one of several shoaling-upwards cycles within the Mission Canyon Formation of the Mississippian Madison Group. The reservoir pay averages 24% porosity, 100 millidarcys permeability, and 50% water saturation. Vertical wells, since field discovery in 1957, typically IP for 70 bopd and 20% water with a rapid decline within a few months to 10 bopd and 90% water. This type of well performance is characteristic of severe water coning for which horizontal development can help to minimize. In late 1994 and early 1995 the Ballantyne Hedges No.7H and GeoResources O. Fossum No.H1 were drilled. The wells recorded IP`s of 280 bopd/5 bwpd and 390 bopd/80 bwpd respectively. After six months of production both wells stabilized at approximately 110 bopd with a 35% water cut. Projections indicate that each horizontal well will recover 250,000 bbls of oil as compared to 115,000 bbls for an average vertical well and will do so in half the time. These early results provide a significant improvement over the vertical production and would seem to be reducing water coning. Three more horizontal wells are planned for the fourth quarter of 1995.

    A complete horizontal molecular orientation of a linear-shaped thermally activated delayed fluorescent guest emitter 2,6-bis(4-(10Hphenoxazin-10-yl)phenyl)benzo[1,2-d:5,4-d′] bis(oxazole) (cis-BOX2) was obtained in a glassy host matrix by vapor deposition. The orientational order of cis-BOX2 depended on the combination of deposition temperature and the type of host matrix. Complete horizontal orientation was obtained when a thin film with cis-BOX2 doped in a 4,4′-bis(N-carbazolyl)-1,1′-biphenyl (CBP) host matrix was fabricated at 200 K. The ultimate orientation of guest molecules originates from not only the kinetic relaxation but also the kinetic stability of the deposited guest molecules on the film surface during film growth. Utilizing the ultimate orientation, a highly efficient organic light-emitting diode with the external quantum efficiency of 33.4 ± 2.0% was realized. The thermal stability of the horizontal orientation of cis-BOX2 was governed by the glass transition temperature (T{sub g}) of the CBP host matrix; the horizontal orientation was stable unless the film was annealed above T{sub g}.

    Objective: To introduce and evaluate a novel approach in treating horizontally impacted mandibular second and third molars. Materials and methods: An orthodontic technique was applied for treatment of horizontally impacted mandibular second and third molars, which included a push-type spring for rotation first, and then a cantilever for extrusion. There were 8 mandibular third molars (M3s) and 2 second molars (M2s) in this study. Tooth mobility, extraction time, the inclination and parallelism of the impacted tooth, alveolar bone height of the adjacent tooth, and the relationship of impacted M3 and the inferior alveolar nerve (IAN) were evaluated. Results: Two horizontally impacted M2s could be upright in the arch and good occlusal relationships were obtained after treatment. All impacted M3s were successfully separated from the IAN, without any neurologic consequences. The average extraction time was 5 minutes. There was a significant change in the inclination and parallelism of the impacted tooth after treatment. A new bone apposition with the average height of 3.2 mm was noted distal to the adjacent tooth. Conclusions: This two-step orthodontic technique as presented here may be a safe and feasible alternative in management of severely horizontally impacted mandibular molars, which achieves a successful separation of M3s from the IAN and an excellent position for M2s.

    Depth-image-based rendering (DIBR) is a method to represent a stereoscopic content. The DIBR consists of a monoscopic center view and an associated per-pixel depth map. Using these two components and given depth condition from a user, the DIBR renders left and right views. The advantages of DIBR are numerous. The user can choose not only the monoscopic or stereoscopic view selectively, but also the depth condition what he prefers when he watches a stereoscopic content. However, in the view of copyright protection, since not only the center view but also each left or right view can be used as a monoscopic content when they are illegally distributed, the watermark signal which is embedded in the center view must have an ability to protect the respective three views. In this study, we solve this problem by exploiting the horizontal noise mean shifting (HNMS) technique. We exploit the fact that the objects in the view are shifted only to horizontal way when the center view renders to the left and right views. Using this fact, the proposed stereoscopic watermarking scheme moves the mean of horizontal noise histogram which is invariant to horizontal shifting, and we achieve good performance as shown in the experimental results.

    Previous to this workshop, realistic lattices have been developed for vertically separated l-in-l (e.g., D.E. Johnson, A.A. Garren) and 2-in-1 (e.g., S. Heifets) magnets as well as for horizontally separated 2-in-l magnets (e.g., SSC RDS). Bringing together the widely separated ({approximately}60-70 cm) beams in a reasonable length of tunnel and keeping the dispersion zero at the interaction point has been difficult in the vertical l-in-l case. Most designs have required spacial 2-in-1 quadrupoles near the interaction point where the beams are separated by 15 cm or less. It is not clear that such magnets, as dictated by some of these lattice designs, can easily be built. The purpose of this exercise is to provide a crossing insertion for a realistic lattice which involves horizontally separated l-in-l magnets. The following horizontal crossing insertions, which incorporate the dispersion suppressors and phase trombones into the major arcs, need no special 2-in-1 magnets near the interaction point. The dispersion at the IP created by the horizontal crossing can be cancelled by the dispersion suppressor and one set of triplets.

    2016-01-01

    OBJECTIVES: Zika virus currently poses a global threat and is a major public health issue throughout Latin America and the Caribbean. However, Zika virus infections in humans have also been observed in other regions, including Southeast Asia, where arboviral diseases are very common. In this study, we summarize the current status of Zika virus in Southeast Asia. This review aims to provide an overview of the current situation and also to suggest ways of adequately managing the emergence of Zika virus in Southeast Asia. METHODS: The literature searching for the reports on Zika virus in Southeast Asia was done using standard database PubMed and the re-analysis and summarization on the reports was done. RESULTS: A limited number of reports have addressed Zika virus disease in Southeast Asia, but it is has been confirmed that a problem already exists. Individual case reports and outbreaks of Zika virus have been confirmed in Southeast Asia. Several reports have also described patients becoming infected after visiting Southeast Asia. In addition, the concurrent circulation of Zika virus with other arboviruses has been confirmed. CONCLUSIONS: As a tropical region with a high prevalence of arboviral diseases, the emergence of Zika virus in Southeast Asia is a major concern. It is essential for local medical personnel to recognize this disease. Given the status of Southeast Asia as a globally important tourist destination, continuous updates on the status of Zika virus in Southeast Asia are required and should be incorporated into global health advisories regarding travel.

    Many Southeast Asians now living in the United States experience severe health problems, attributable to physical trauma and inadequate health care in Asia, and low socioeconomic status in this country. Evidence indicates that despite their health problems, Southeast Asian refugees underuse the American health care system. Cultural reasons for this underuse are examined. Southeast Asian cultural attitudes toward suffering, such as beliefs that suffering is inevitable or that one's life span is predetermined, can cause Southeast Asians not to seek health care. Cultural beliefs about the sources of illness and correspondingly appropriate forms of treatment can be a barrier to Western health care. Many lack familiarity with Western diagnostic techniques and treatments and thus are apprehensive. Health care providers' ignorance of Southeast Asian cultures can interfere with communication with patients, resulting in culturally irrelevant services or misinterpretation of side effects of Southeast Asian folk medicines. Southeast Asians' lack of familiarity with American culture can make health care services geographically and economically inaccessible and can cause Southeast Asians to be ignorant of available services or how to access them. An understanding of Southeast Asian cultures and additional outreach efforts by Western medical practitioners and health care providers are needed to improve the use of health care services by Southeast Asian refugees in this country.

    1999-01-01

    Two vastly different phenomena, impact and salt diapirism, have been proposed for the origin of Upheaval Dome, a spectacular scenic feature in southeast Utah. Detailed geologic mapping and seismic refraction data indicate that the dome originated by collapse of a transient cavity formed by impact. Evidence is as follows: (1) sedimentary strata in the center of the structure are pervasively imbricated by top-toward-the-center thrust faulting and are complexly folded as well; (2) top-toward-the-center normal faults are found at the perimeter of the structure; (3) clastic dikes are widespread; (4) the top of the underlying salt horizon is at least 500 m below the surface at the center of the dome, and there are no exposures of salt or associated rocks of the Paradox Formation in the dome to support the possibility that a salt diapir has ascended through it; and (5) planar microstructures in quartz grains, fantailed fracture surfaces (shatter surfaces), and rare shatter cones are present near the center of the structure. We show that the dome formed mainly by centerward motion of rock units along listric faults. Outcrop-scale folding and upturning of beds, especially common in the center, are largely a consequence of this motion. We have also detected some centerward motion of fault-bounded wedges resulting from displacements on subhorizontal faults that conjoin and die out within horizontal bedding near the perimeter of the structure. The observed deformation corresponds to the central uplift and the encircling ring structural depression seen in complex impact craters. Copyright 1999 by the American Geophysical Union.

    A versatile mechanical device provides support for a user engaged in any of a variety of resistive exercises in a substantially horizontal orientation. The unique features and versatility of the device promise to be useful in bedrest studies, rehabilitation, and specialized strength training. The device affords a capability for selectively loading and unloading of portions of the user s body through its support mechanisms, so that specific parts of the body can be trained with little or no effect on other parts that may be disabled or in the process of recovery from injury. Thus, the device is ideal for rehabilitation exercise programs prescribed by physicians and physical therapists. The capability for selective loading and support also offers potential benefits to strength and conditioning trainers and athletes who wish to selectively strengthen selected parts. The principal innovative aspect of the device is that it supports the subject s weight while enabling the subject, lying substantially horizontally, to perform an exercise that closely approximates a full standing squat. The device includes mechanisms that support the subject in such a way that the hips are free to translate both horizontally and vertically and are free to rotate about the line connecting the hips. At the same time, the shoulders are free to translate horizontally while the upper back is free to rotate about the line connecting the shoulders. Among the mechanisms for hip motion and support is a counterbalance that offsets the weight of the subject as the subject s pelvis translates horizontally and vertically and rotates the pelvis about the line connecting the hips. The counterbalance is connected to a pelvic support system that allows these pelvic movements. The subject is also supported at the shoulder by a mechanism that can tilt to provide continuous support of the upper back while allowing the rotation required for arching the back as the pelvis is displaced. The shoulder support

    1984-06-01

    ELF Aquitaine used horizontal drilling during a pilot test program to bring commercial production from its Rospo Mare oil discovery in the Adriatic, which would have been a costly disappointment if drilled by a conventional vertical well bore. Rospo Mare is a large reservoir containing a top column of highly viscous crude underlain by a water column. The company felt that a well bore that penetrated the reservoir vertically would bring early flooding of the oil column and yield only water. By penetrating the reservoir with a horizontal well drilled high in the oil column, the well successfully produced on numerous tests from Oct. 1982 until the end of the test program in 1983. Production was termed excellent, with productivity during tests reportedly reaching ca 15 times the rate produced from nearby vertical wells. However, ELF said the results usually average ca 5 times the usual rate of vertical wells.

  13. Stability of vertical and horizontal axis Levitrons

    Michaelis, M. M.; Taylor, D. B.

    2015-11-01

    The stability of the new horizontal axis Levitron3 is compared with that of the vertical axis device. The rotation frequency ranges are similar because they are determined by the same precessional micro-trap, for which some theory is given. But the macro-trap of the horizontal axis system gives it far greater mechanical stability. Field-line studies allow this to be more easily visualized. The greater stability allows for educational experiments which could only be contemplated with the old Levitron: driven precession and nutation and motion along the field lines. These experiments illustrate some very fundamental space dynamics and several other topics. The enhanced stability may also lead to electro-mechanical applications.

  14. Kinematics of horizontal and vertical caterpillar crawling.

    PubMed

    van Griethuijsen, Linnea I; Trimmer, Barry A

    2009-05-01

    Unlike horizontal crawling, vertical crawling involves two counteracting forces: torque rotating the body around its center of mass and gravity resisting forward movement. The influence of these forces on kinematics has been examined in the soft-bodied larval stage of Manduca sexta. We found that crawling and climbing are accomplished using the same movements, with both segment timing and proleg lift indistinguishable in horizontal and vertical locomotion. Minor differences were detected in stride length and in the delay between crawls, which led to a lower crawling speed in the vertical orientation. Although these differences were statistically significant, they were much smaller than the variation in kinematic parameters between animals. The ability of Manduca to crawl and climb using the same movements is best explained by Manduca's relatively small size, slow speed and strong, controlled, passive grip made possible by its proleg/crochets.

  15. Active vibration suppression of helicopter horizontal stabilizers

    NASA Astrophysics Data System (ADS)

    Cinquemani, Simone; Cazzulani, Gabriele; Resta, Ferruccio

    2017-04-01

    Helicopters are among the most complex machines ever made. While ensuring high performance from the aeronautical point of view, they are not very comfortable due to vibration mainly created by the main rotor and by the interaction with the surrounding air. One of the most solicited structural elements of the vehicle are the horizontal stabilizers. These elements are particularly stressed because of their composite structure which, while guaranteeing lightness and strength, is characterized by a low damping. This work makes a preliminary analysis on the dynamics of the structure and proposes different solutions to actively suppress vibrations. Among them, the best in terms of the relationship between performance and weight / complexity of the system is that based on inertial actuators mounted on the inside of the horizontal stabilizers. The work addresses the issue of the design of the device and its use in the stabilizer from both the numerical and the experimental points of view.

  16. Sand removal from heavy oil horizontal wells

    SciTech Connect

    Dedora, G.

    1995-12-31

    Oil production from heavy oil horizontal wells continues to be hindered by sand production and bridging resulting in total or partial shut-off of the wellbore. These bridges cannot be removed using circulation due to the low pressure of most heavy oil reservoirs. Removing these bridges using vertical or slanted well cleanout technology has proven to be difficult and costly, particularly if the production lateral is greater than 300-400 metres. With most laterals stretching beyond 1000 metres, producers and service companies have been in search of more effective alternatives. This challenge brought forth several new concepts in horizontal well cleanout technology involving artificial lift systems capable of continuous advancement into the lateral while producing high concentrations of sand. During the cleanout procedures, wellbore pressure is controlled thus avoiding high volumes of lost workover fluids. This presentation discusses these cleanout techniques as well as the positive and negative features of each.

    Artificial bilayer containing reconstituted ion channels, transporters and pumps serve as a well-defined model system for electrophysiological investigations of membrane protein structure–function relationship. Appropriately constructed microchips containing horizontally oriented bilayers with easy solution access to both sides provide, in addition, the possibility to investigate these model bilayer membranes and the membrane proteins therein with high resolution fluorescence techniques up to the single-molecule level. Here, we describe a bilayer microchip system in which long-term stable horizontal free-standing and hydrogel-supported bilayers can be formed and demonstrate its prospects particularly for single-molecule fluorescence spectroscopy and high resolution fluorescence microscopy in probing the physicochemical properties like phase behavior of the bilayer-forming lipids, as well as in functional studies of membrane proteins.

The storage system (10) includes a plurality of dry storage modules (26) which accept the canister (12) from the transfer cask (14) and provide for appropriate shielding about the canister (12). Each module (26) also provides for air cooling of the canister (12) to remove the decay heat of the irradiated fuel assemblies (20). The modules (26) can be interlocked so that each module (26) gains additional shielding from the next adjacent module (26). Hydraulic rams (30) are provided for inserting and removing the canisters (12) from the modules (26).

    1993-01-01

    Condensation heat transfer in a horizontal rectangular duct was experimentally and analytically investigated. To prevent the dripping of condensate on the film, the experiment was conducted inside a horizontal rectangular duct with vapor condensing only on the bottom cooled plate of the duct. R-113 and FC-72 (Fluorinert Electronic Fluid developed by the 3M Company) were used as the condensing fluids. The experimental program included measurements of film thickness, local and average heat transfer coefficients, wave length, wave speed, and a study of wave initiation. The measured film thickness was used to obtain the local heat transfer coefficient. The wave initiation was studied both with condensation and with an adiabatic air-liquid flow. The test sections used in both experiments were identical.

    2004-10-01

    In this paper we present an analysis of a new configuration for achieving spin stabilized magnetic levitation. In the classical configuration, the rotor spins about a vertical axis; and the spin stabilizes the lateral instability of the top in the magnetic field. In this new configuration the rotor spins about a horizontal axis; and the spin stabilizes the axial instability of the top in the magnetic field.

    The principle of optical scanning holography (OSH) is proposed to acquire horizontal-parallax-only (HPO) holographic information electronically. We first briefly summarize the results of OSH and then discuss how HPO-electronic holographic information can be acquired using OSH. Finally we provide simulations to illustrate and clarify the proposed idea. Although many ideas of HPO-holography have been proposed and studied, to the best of our knowledge, this is the first proposed electronic technique to acquire HPO-holographic information.

    A theoretical model of horizontal-wellbore failure has been developed based on maximum-normal-stress theory (for tensile fracturing) and Drucker-Prager failure theory (for compressive failure) under openhole conditions. This model may be used to help determine the permissible borehole operating-pressure range, providing a convenient scheme for selecting borehole pressure to minimize the risk of borehole failure during drilling and production.

    1999-11-08

    The work on modeling hydraulically fractured horizontal wells has moved forward. A literature review on the subject was done and some of the existing models have been coded and applied to example problems for evaluation purposes. Previous work on the elects of heterogeneities on the performance of horizontal wells was continued by conducting a sensitivity study on various parameters that were kept constant in the earlier study. For example, we have studied the elect of gas cap and aquifer size, well location, fluid viscosity, etc. The experimental work on using horizontal wells as injectors and producers in a gas injection gravity drainage process continued. New and repeat experiments were conducted. Work on streamline grids was advanced by considering example problems with highly distorted grids which cannot be directly used for flow simulation. Grid smoothing and domain mapping techniques were investigated to handle such situations. A technique was developed for the computation o f well index with consideration to wellbore pressure drop. A recently developed reservoir/wellbore coupling model was used for this purpose.

    PROBLEM ADDRESSED: Opportunities for residents in a family medicine program to experience continuity of care with a group of patients and to be immersed in the role of a family physician were thought by faculty to be insufficient. OBJECTIVES OF THE PROGRAM: To enhance residents' experience of continuity of care with a group of patients; to create a model for training that better simulates clinical practice; and to position core family medicine experiences as the central and continuing focus of the residency program. MAIN COMPONENTS OF THE PROGRAM: The new curriculum replaces block rotations in family medicine with "horizontal" experiences comprising 3 half-days of patient care and 1 half-day seminar each week for all residents through both years of the program. The remaining time in first year is spent on the major disciplines--medicine, pediatrics, emergency, and obstetrics--for which a horizontal family medicine-centred experience has also been introduced. The second-year curriculum is flexible and largely self-directed. Initial evaluations indicate improved continuity of care of family practice patients and broadened clinical exposure for residents. The program has been fully accredited by the College. CONCLUSIONS: A horizontal curriculum in family medicine, designed to address perceived deficiencies in the traditional block rotational model of training, can be developed and implemented in an urban teaching hospital.

  10. Vertical and horizontal seismometric observations of tides

    Lambotte, S.; Rivera, L.; Hinderer, J.

    2006-01-01

    Tidal signals have been largely studied with gravimeters, strainmeters and tiltmeters, but can also be retrieved from digital records of the output of long-period seismometers, such as STS-1, particularly if they are properly isolated. Horizontal components are often noisier than the vertical ones, due to sensitivity to tilt at long periods. Hence, horizontal components are often disturbed by local effects such as topography, geology and cavity effects, which imply a strain-tilt coupling. We use series of data (duration larger than 1 month) from several permanent broadband seismological stations to examine these disturbances. We search a minimal set of observable signals (tilts, horizontal and vertical displacements, strains, gravity) necessary to reconstruct the seismological record. Such analysis gives a set of coefficients (per component for each studied station), which are stable over years and then can be used systematically to correct data from these disturbances without needing heavy numerical computation. A special attention is devoted to ocean loading for stations close to oceans (e.g. Matsushiro station in Japon (MAJO)), and to pressure correction when barometric data are available. Interesting observations are made for vertical seismometric components; in particular, we found a pressure admittance between pressure and data 10 times larger than for gravimeters for periods larger than 1 day, while this admittance reaches the usual value of -3.5 nm/s 2/mbar for periods below 3 h. This observation may be due to instrumental noise, but the exact mechanism is not yet understood.

    Objetive: The aim of this study was to analyze possible horizontal transmission patterns of S. mutans among 6-7-yr-old schoolchildren from the same class, identifying genotypes and their diversity and relationship with caries disease status. Study Design: Caries indexes and saliva mutans streptococci and lactobacilli counts were recorded in 42 schoolchildren. Mutans streptococci colonies were identified by means of biochemical tests and all S. mutans strains were genotyped by arbitrarily primed polymerase chain reaction. A child was considered free of S. mutans when it could not be isolated in 3 samples at 1-week intervals. Results: S. mutans was isolated in 30 schoolchildren: 20 having one genotype and 10 two genotypes. Higher mutans streptococci and caries index values were found in those with two genotypes. Five genotypes were isolated in more than 1 schoolchild and one of these was isolated in 3 schoolchildren. Our results suggest that horizontal transmission may take place. Conclusion: Schoolchildren aged 6-7 yrs may be the source of mutual transmission of S. mutans. Key words:Streptococcus mutans, Horizontal transmission, AP-PCR, genotyping PMID:22143733

  12. Changing rainfall and humidity within Southeast Texas.

    PubMed

    Smith, Robert Kennedy

    2015-01-01

    Southeast Texas houses a precipitation transition zone between drier conditions to the North and West and some of the wettest parts of the continental U.S. to the East. The Region has seen an increase in its reported normal annual precipitation totals in recent decades. In order to determine if the additional rainfall has been influenced by warming temperatures or is within the variability of the State's long-term drought cycles, several analyses were performed on historical climate data. The analyses answered several questions: Have global and regional climate change models predicted precipitation increases in Southeast Texas and are future increases expected? Do historical monthly precipitation totals at various sites in the region provide clear trends of wetter conditions that can be discerned from long-term drought cycles? Are rainfall patterns changing with less frequent, heavier rain events? Do the reported increases in annual rainfall actually lead to wetter conditions in the region? Climate models have not predicted larger annual average precipitation totals nor do they forecast increases for Southeast Texas. While recent decades may have seen more rain relative to earlier periods, a combined analysis of observation stations across different parts of the Region shows that long-term trends are dependent on when the data is selected relative to a drought cycle. While some stations show larger amounts of rain falling during fewer days, these trends do not hold across all periods. An examination of hourly data does not show an increase in extreme rainfall events or a decrease in the number of hours during which rain has fallen. Even though rainfall has not decreased, average relative humidity has fallen. This suggests that the area is drying even with steady or increasing amounts of rain.

    With an understudied amphibian fauna, the highest deforestation rate on the planet and high harvesting pressures, Southeast Asian amphibians are facing a conservation crisis. Owing to the overriding threat of habitat loss, the most critical conservation action required is the identification and strict protection of habitat assessed as having high amphibian species diversity and/or representing distinctive regional amphibian faunas. Long-term population monitoring, enhanced survey efforts, collection of basic biological and ecological information, continued taxonomic research and evaluation of the impact of commercial trade for food, medicine and pets are also needed. Strong involvement of regional stakeholders, students and professionals is essential to accomplish these actions. PMID:20007165

    Tribal people in southeast Idaho sincerely desire that archaeologists include Shoshone concepts of spirituality when investigating archaeological materials and sites. However, most archaeologists and resource managers have little understanding about these concepts and this creates difficulties. We examine two important aspects of the Shoshone soul, Mugua’ and Nabushi’aipe, and discuss how understanding these attributes aid in explaining why certain archaeological remains are considered sacred. A greater understanding of Shoshone spirituality will begin to bridge the needs of both tribal people and archaeologists.

    Rainfall in southeast Texas, which ranged in amounts from about 8 to more than 28 inches during October 15–19, 1994, caused severe flooding in parts of a 38-county area. A combination of meteorological events—residual atmospheric moisture over southern Texas associated with Hurricane Rosa from the Pacific Coast of Mexico and low-level moisture from the Gulf of Mexico drawn inland to a warm front by a strong low-pressure system over the southern Rocky Mountains—spawned vigorous thunderstorms that produced rainfall amounts that may exceed records for the area.

  18. High accuracy diffuse horizontal irradiance measurements without a shadowband

    Schlemmer, J.A; Michalsky, J.J.

    1995-12-31

    The standard method for measuring diffuse horizontal irradiance uses a fixed shadowband to block direct solar radiation. This method requires a correction for the excess skylight blocked by the band, and this correction varies with sky conditions. Alternately, diffuse horizontal irradiance may be calculated from total horizontal and direct normal irradiance. This method is in error because of angular (cosine) response of the total horizontal pyranometer to direct beam irradiance. This paper describes an improved calculation of diffuse horizontal irradiance from total horizontal and direct normal irradiance using a predetermination of the angular response of the total horizontal pyranometer. We compare these diffuse horizontal irradiance calculations with measurements made with a shading-disk pyranometer that shields direct irradiance using a tracking disk. Results indicate significant improvement in most cases. Remaining disagreement most likely arises from undetected tracking errors and instrument leveling.

    New alkaliphilic anaerobic fermentative bacteria, strains Z-7981 and Z-7981', with Gram-positive cell walls, were isolated from the cellulolytic community from the soda lake Nizhnee Beloye, south-east of Baikal. Cells were motile rods, which differed in dimensions but, according to 98% DNA/DNA homology, belonged to the same species. Strain Z-7981 was chosen as the type and studied in detail. It did not produce spores and its cells were non-thermoresistant. It was a true alkaliphile with a growth range from pH 7.1 to pH 10.1 and optimal pH for growth at pH 9.1. It was obligately dependent on Na(+) and carbonate ions but not on Cl(-). Growth occurred in media with total sodium content from 0.076 M to 1.27 M Na(+ )with a broad optimum from 0.25 to 0.86 M Na(+). Growth showed an optimum at 35 degrees C, with absence of growth above 46 degrees C. The organism was aerotolerant and was capable of fermentation in non-reducing medium at less than 4.75% O(2) in the gas phase. Strain Z-7981 fermented mono- and disaccharides, sugar alcohols, but only glutamate and cysteine among the amino acids, and the proteinaceous substrates, chitin and dried Spirulina biomass. Fermentation products were acetate and ethanol. Fe(3+) was reduced in a process that yielded no energy. Phylogenetically the new organism belonged to cluster XI of the Gram-positive bacteria with low G+C content and its closest neighboring taxon was Tindallia magadiensis. However, according to its phenotypic and genotypic characters it did not belong to any known genus from this group. We suggest a new genus and species with the name Anoxynatronum sibiricum and strain Z-7981 as its type (=DSM15060).

  5. Demand management implementation in Southeast Asia

    1995-12-31

    The need to apply transportation system management, to developing countries is urgent. Attempts to alleviate severe traffic congestion in their metropolises have so far failed to provide adequate solutions. The countries are faced with many difficulties because of the lack of sufficient financial resources together with their complex internal administrative and political problems. They are incapable of providing sufficient road space to cope with the escalating demand in private automobiles. This has led to excessive delays in urban traveling, environmental pollution problems, decline of road-based public transit services and deterioration of the quality of life in these metropolises. Demand management, in use for decades in the Western world, has also been recognized in Singapore`s famous area licensing scheme (ALS) making other Southeast Asian Metropolises aware of its advantages as an alternative in solving their chaotic traffic problems. However, realization is far different from implementation and still many metropolises are not able to apply the technique. Singapore and Thailand, two leaders among many other Southeast Asian regions in economics, tourism, trade and industry handle their problems far differently, especially the traffic congestion problem. While a number of demand management schemes have been implemented successfully in Singapore since 1975, Bangkok is still struggling to implement such measures to alleviate severe traffic congestion problems. This article intends to high light the successful practices and unsuccessful attempts of demand management techniques applied in Singapore and Bangkok.

  6. A trichinosis outbreak among Southeast Asian refugees.

    1992-06-15

    The number of cases of trichinosis reported to Centers for Disease Control has declined steadily, with an average of only 44 cases per year from 1984 through 1988. This decline was almost entirely due to a reduction in cases acquired from ingestion of fresh commercial pork. However, from July 21 through September 3, 1990, 90 (72%) of 125 Southeast Asian refugees from six states and Canada developed trichinosis after attending or eating pork sausage taken from a wedding held in Des Moines, Iowa, on July 14, 1990. Eating uncooked sausage prepared at home from commercially obtained pork was associated with the development of this illness (odds ratio = 34.0, p less than 0.001). Analysis by amount of pork consumed was significant (Mann-Whitney U rank sum test, p less than 0.001). This outbreak of trichinosis in Iowa is the fourth reported within the last 15 years among the 900,000 Southeast Asian refugees resident in the United States and one of the largest reported outbreaks in US history. The continued presence of Trichinella spiralis in commercial pork emphasizes the need for further education and control measures for persons whose dietary habits place them at risk for developing trichinosis.

    Amphibian trade is known to facilitate the geographic spread of pathogens. Here we assess the health of amphibians traded in Southeast Asia for food or as pets, focusing on Batrachochytrium dendrobatidis (Bd), ranavirus and general clinical condition. Samples were collected from 2,389 individual animals at 51 sites in Lao PDR, Cambodia, Vietnam and Singapore for Bd screening, and 74 animals in Cambodia and Vietnam for ranavirus screening. Bd was found in one frog (n = 347) in Cambodia and 13 in Singapore (n = 419). No Bd was found in Lao PDR (n = 1,126) or Vietnam (n = 497), and no ranavirus was found in Cambodia (n = 70) or Vietnam (n = 4). Mild to severe dermatological lesions were observed in all East Asian bullfrogs Hoplobatrachus rugolosus (n = 497) sampled in farms in Vietnam. Histologic lesions consistent with sepsis were found within the lesions of three frogs and bacterial sepsis in two (n = 4); one had Gram-negative bacilli and one had acid-fast organisms consistent with mycobacterium sp. These results confirm that Bd is currently rare in amphibian trade in Southeast Asia. The presence of Mycobacterium-associated disease in farmed H. rugolosus is a cause for concern, as it may have public health implications and indicates the need for improved biosecurity in amphibian farming and trade.

  8. Examining Stratocumulus Properties over the Southeast Pacific

    McCoy, Isabel; Muhlbauer, Andreas; Wood, Robert

    2012-10-01

    Variability in Stratocumulus (Sc) clouds is important to the planetary albedo and radiation budget because they reflect incoming shortwave radiation back to space thereby cooling the atmosphere. Understanding more of their micro and macro physical properties is essential to reduce uncertainty in global climate model prediction and add confidence in future climate predictions. In 2006, Robert Wood and Dennis Hartmann characterized Sc clouds into four main categories based on their morphology and level of mesoscale organization. In this poster, we focus on two of these categories, namely open and closed cells, because of their differing cloud coverage. We use satellite data (from NASA's CloudSat and Goes 10) in combination with the occurrence identifications to develop statistics on the microphysical characteristics for each type of cloud. The results compare successfully to the aircraft data from a recent campaign sampling the same region (the VOCALS Regional Experiment over the Southeast Pacific for Oct. and Nov. of 2008). We find that, when the two cases are contrasted, the open cells have both a higher drizzle rate (at cloud base) and a larger range of rates than the closed. Further, this method of characterizing satellite data to derive pertinent results about Sc clouds is successful. Whether these properties are specific to the Southeast Pacific Sc clouds, and if similar results can be found for expanded time and area, is the topic of future research.

  4. Status of LLRW disposal in the Southeast Compact Region

    Hunter, R. [HRS Buckner, T.

    1996-10-01

    In 1983, eight states - Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, and Virginia - became members of the Southeast Compact through enactment of the Southeast Compact Law. The Southeast was one of the three regions which began with an existing regional disposal facility. That facility, located in Barnwell, South Carolina, had been operating under private management since 1971. It was expected that the facility in South Carolina would serve as the first regional facility and would close no later than December 31, 1991, when a second regional facility would be sited and operational. In September of 1986, the Southeast Compact Commission chose North Carolina as the second host state to develop the next disposal facility for the southeast region. In accordance with the original compact negotiations, the details of the actual siting, construction and operation of the facility were left to the State of North Carolina. The Southeast Compact now exists in a time of change and uncertainty and it is difficult to assess where the region is going in the future. North Carolina is still the designated host state and the Commission still expects North Carolina to fulfill its legal obligation to open a disposal facility. The region cannot count on Barnwell to be available tomorrow, next week or ten years from now and Envirocare cannot handle all of the waste streams from the Southeast and may never be able to do so. A regional disposal facility is still needed in the Southeast.

  6. Horizontal distribution of mixed cloud type scene

    NASA Astrophysics Data System (ADS)

    Guillaume, A.; Kahn, B. H.; Yue, Q.; Wong, S.; Manipon, G.; Hua, H.; Wilson, B. D.; Wang, T.; Fetzer, E. J.

    We describe a novel method to uniquely characterize and quantify the scale dependence of mixed cloud scene geometry using cloud type classification reported with the 94GHz CloudSat radar. Only a fraction of all possible combinations of cloud types are observed at any along-track length scale considered. Cloud scenes most frequently contain only one or two cloud types. We show how cloud occurrence depends on the grid cell spatial resolution used to define cloud scenes. A maximum number of observed cloud scenes occur near 100 km with fewer cloud type combinations at smaller and larger scales. We then quantify the cloud lengths along the CloudSat track using both the cloud top classification and the vertical structure of cloud classification separately for each of the nine cloud types defined by CloudSat and for all clouds considered independent of cloud type. While the individual cloud types do not follow a clear power law behavior as a function of horizontal or vertical scale, a robust power law scaling of cloud geometry is observed when cloud type is not considered. The power law scaling exponent of horizontal length is approximated by β ≈ -5/3 over two to three orders of magnitude. The power law scaling exponent of vertical length is approximated by β ≈ -7/3 over two orders of magnitude. These exponents are in agreement with previous studies using numerical models, satellite, and in situ aircraft observations. In particular, the anisotropy in the horizontal and vertical scaling are nearly identical to recent aircraft observations of wind kinetic energy spectra, suggesting the underlying three-dimensional cloud geometry is strongly related to kinetic energy spectra.

  7. Convective mixing in formations with horizontal barriers

    NASA Astrophysics Data System (ADS)

    Elenius, Maria T.; Gasda, Sarah E.

    2013-12-01

    It has been shown that convective mixing in porous media flow is important for applications such as saltwater intrusion and geological storage of carbon dioxide. In the latter case, dissolution from the injected phase to the resident brine is assisted by convective mixing, which leads to enhanced storage security through reduced buoyancy. Here, we focus on the effect of horizontal barriers on the efficiency of convective mixing. Previous investigations of the effect of heterogeneity on mixing efficiency have focused on random permeability fields or barriers of small extent compared to the intrinsic finger wavelength. The effect of horizontal barriers of larger extent, such as mudstone inclusions or thin shale deposits, has not been given sufficient attention. We perform detailed numerical investigations to represent the continuous solution of this problem in semi-infinite domains with barriers arranged in a periodic manner. The results show that mass flux into the domain, which is a measure of the efficiency of redistribution of the solute, is inversely proportional to the barrier length and proportional to the horizontal and vertical aperture between the barriers, for the cases studied. The flow structure is complex, and it depends not only on the total area of barriers but also largely on the distribution of barriers. Therefore, neither simple analytical models nor simple upscaling methods that lack information about the flow paths, can be used to predict the behavior. However, we compute the effective vertical permeability by flow-based upscaling and show that it can be used to directly obtain a first-order approximation to the mass flux into the domain.

    2014-01-01

    Background There has recently been an increase in HIV infection rates among men who have sex with men (MSM). This study aimed at investigating risk factors associated with incident HIV infection in a MSM cohort–Project Horizonte, Belo Horizonte, Minas Gerais, Brazil. Methodology This is a nested case-control study in an ongoing open cohort of homosexual and bisexual men, carried out in 1994–2010, during which 1,085 volunteers were enrolled. Each HIV seroconverted volunteer (case) was compared with three randomly selected HIV negative controls, matched by admission date and age (±3 years). During follow-up, 93 volunteers seroconverted and were compared with 279 controls. Principal Findings The risk factors associated with HIV seroconversion were: contact with partner’s blood during sexual relations (OR 3.7; 95% CI 1.2–11.6), attendance at gay saunas in search for sexual partners (OR 2.6; 95% CI 1.3–5.4), occasional intake of alcohol when flirting and engaging in sexual activity (OR 2.5; 95% CI 1.3–5.1), inconsistent use of condoms in receptive anal sex (OR 2.4; 95% CI 1.1–5.4), little interest to look up information about AIDS (OR 2.6; 95% CI 1.0–6.7) particularly in newspapers (OR 3.4; 95% CI 1.4–8.1). Conclusions This study shows that MSM are still engaging in risk behavior, such as unprotected anal intercourse, despite taking part in a cohort study on various preventive measures. New preventive strategies in touch with the epidemic’s development and the specificities of this particular population are needed. PMID:25279670

  9. In situ bioremediation using horizontal wells

    SciTech Connect

    1995-04-01

    In Situ Bioremediation (ISB), which is the term used in this report for Gaseous Nutrient Injection for In Situ Bioremediation, remediates soils and ground water contaminated with volatile organic compounds (VOCs) both above and below the water table. ISB involves injection of air and nutrients (sparging and biostimulation) into the ground water and vacuum extraction to remove .VOCs from the vadose zone concomitant with biodegradation of VOCs. The innovation is in the combination of 3 emerging technologies, air stripping, horizontal wells, and bioremediation via gaseous nutrient injection with a baseline technology, soil vapor extraction, to produce a more efficient in situ remediation system.

    NASA Astrophysics Data System (ADS)

    Michaelis, Max M.

    2014-01-01

    After a brief history of the Levitron, the first horizontal axis Levitron is reported. Because it is easy to operate, it lends itself to educational physics experiments and analogies. Precession and nutation are visualized by reflecting the beam from a laser pointer off the ‘spignet’. Precession is fundamental to nuclear magnetic resonance, magnetic resonance imaging, particle traps and the movement of bodies in space. Longitudinal and lateral bounce behaviour is explained via ‘the principle of gentle superposition’ of two traps: the micro-precessional and the macro-trap. Theory is initiated. Scaling experiments are mentioned. Industrial applications might follow. Patent pending.

  11. Horizontal stability of a bouncing ball.

    PubMed

    McBennett, Brendan G; Harris, Daniel M

    2016-09-01

    We present an investigation of a partially elastic ball bouncing on a vertically vibrated concave parabolic surface in two dimensions. In particular, we demonstrate that simple vertical motion, wherein the ball bounces periodically at the parabola's vertex, is unstable to horizontal perturbations when the parabolic coefficient defining the surface shape exceeds a critical value. The result is a new periodic solution where the ball bounces laterally over the vertex. As the parabola is further steepened, this new solution also becomes unstable which gives rise to other complex periodic and chaotic bouncing states, all characterized by persistent lateral motion.

    PubMed

    2015-06-01

    We consider the transition of a horizontally vibrated monodisperse granular monolayer between its condensed state and its three-dimensional gaseous state as a function of the vibration parameters, amplitude, and frequency as well as particle number density. The transition is characterized by an abrupt change of the dynamical state which leaves its fingerprints in several measurable quantities including dissipation rate, sound emission, and a gap size which characterizes the sloshing motion of the material. The transition and its pronounced hysteresis is explained through the energy due to the collective motion of the particles relative to the container.

    Shamsundar, N.; Krishna, C.N.

    1999-07-01

    The thermohaline stability of horizontal layers of saltwater (with cold fresh water on top of warm salty water) was studied using analytical and numerical methods. The marginal oscillatory instability state was calculated for different boundary conditions for uniform s well as for nonuniform temperature and salinity gradients. A correlation was developed to use the ratio of the mean gradient to the maximum gradient to enable stability results for nonlinear gradients to be extrapolated from simpler results for linear gradients. Contrary to published expectations, localized stability criteria are not suitable for calculating the effects of nonlinear temperature gradients.

  14. Does horizontal transmission invalidate cultural phylogenies?

    PubMed Central

    Greenhill, Simon J.; Currie, Thomas E.; Gray, Russell D.

    2009-01-01

    Phylogenetic methods have recently been applied to studies of cultural evolution. However, it has been claimed that the large amount of horizontal transmission that sometimes occurs between cultural groups invalidates the use of these methods. Here, we use a natural model of linguistic evolution to simulate borrowing between languages. The results show that tree topologies constructed with Bayesian phylogenetic methods are robust to realistic levels of borrowing. Inferences about divergence dates are slightly less robust and show a tendency to underestimate dates. Our results demonstrate that realistic levels of reticulation between cultures do not invalidate a phylogenetic approach to cultural and linguistic evolution. PMID:19324763

    PubMed

    2010-01-01

    Herbivorous insects may attack eucalyptus causing economic losses. One of these pests is the moth Euselasia apisaon Dahman, a key pest in the basin of middle Rio Doce. Here we studied the survival of pupae of this moth in Eucalyptus and in understorey plants and tested the hypotheses: i) live pupae are more abundant in plants of the understorey than in eucalyptus, ii) there is no difference between the abundance of pupae in different plants of the understorey. We sampled three areas cultivated with eucalyptus in Belo Oriente, MG, and samples were taken in five plots each area, getting five branches of each plant and of five eucalyptus trees that bordered the plot. The proportion of live and dead pupae and the mortality rate were estimated. The abundance of live pupae was higher in the understorey and the mortality rate of pupae was the same among different families of plants of the understorey. It is possible the larger available leaf area of understorey plants justify the greater abundance of live pupae in this habitat, however, avoidance of feeding habitat to finish the life cycle is also a possible explanation. Mortality rate in plants of the understorey points to an equal pressure of natural enemies on the pupae. These appointments help us to understand the dynamics of pests in eucalyptus plantations, providing important information to support actions against pests in natural environments.

    Amazon river turtles are increasingly threatened by habitat loss and alteration due to the Brazilian energy policy based on construction of hydroelectric dams, meanwhile, populational studies remain scarce. We described the population structure, and established body allometric relationships of Podocnemis unifilis in the Terra do Meio Ecological Station in the Iriri River, tributary of the Xingu River upstream the Belo Monte dam under construction Turtles were captured by hand net and diving in 2012 and 2013 dry seasons, and 2013 rainy season. A total of 728 males, 296 females and four juveniles were captured. Adult sex ratio was male-biased by 9.15 ♂:1 ♀. Females were significantly larger than males. Mean straight carapace length was 268.9 ± 46.7 mm (165 - 403) for females; and 232.7 ± 24.8 mm (167 - 303) for males. The sexes were morphologically distinct in function of a proportionally larger plastron, and higher carapace, on females. Allometric relationships between straight carapace length and other morphometric traits were strong for males (R2 range = 0.87 - 0.96 and females (R2 range =0.79 - 0.98. Exploitation of P. unifilis in biomass extirpated from the Middle Xingu River may be estimated from body parts found post-consumption by the presented regressions.

  17. Horizontal Air Bearing Experiment Number 1

    SciTech Connect

    Clauson, T.L.

    1999-08-31

    The Horizontal Air Bearing Experiment No.1 is a series of tests intended to further the understanding of rotational dynamics. A simple experimental assembly is rotated using the Horizontal Air Bearing and allowed to spin freely as the internal rotational damping is measured. The low friction of the bearing effectively isolates the test assembly, allowing the internal damping of the test object to be evaluated. The experimental assembly is composed of an aluminum ball within a spherical cavity. A flanged pipe section and an auxiliary adapter plate secure the assembly to the Air Bearing interface plate. Three aluminum balls are interchanged to vary test parameters. The aluminum balls are free to move independently as the entire assembly rotates. The aluminum balls vary in diameter and/or surface finish. While the diameter and surface finish is varied, the space between the ball and socket is dry. To examine the effect of viscosity, the space is filled with a lubricant while the ball diameter and surface finish is held constant.

    This patent describes a method for thermal stimulation and production of a viscous hydrocarbon from a reservoir having a productive layer which retains the hydrocarbon until the latter is made flowable by contact with a hot stimulating medium. The method includes the steps of: forming a borehole having a substantially horizontal segment which transverses the productive layer, registering a well completion in the borehole which includes; an elongated perforate well liner, a fluid conduit extending through the liner and having a discharge end, and a well head at the liner upper end communicated with the fluid conduit, positioning a variable length flow diverter in the liner adjacent to the fluid conduit discharge end, whereby to define a quasi-barrier in the liner which is pervious to passage of the hot stimulating medium, and which divides the liner into injection and production segments respectively, heating the productive layer about the substantially horizontal segment of the elongated liner, introducing a pressurized stream of the hot stimulant through the fluid conduit and into the liner injection segment, and producing hydrocarbon emulsion which flows into the liner production segment.

    Well-performance forecasts suggests that many horizontal wells could be good candidates for matrix stimulation, even in certain reservoirs where vertical wells should be stimulated only by hydraulic fracturing. This paper presents a technique for the matrix treatment of horizontal wells to allow uniform distribution of the stimulation fluids. It involves pumping a reactive fluid through coiled tubing and an inert fluid through the coiled-tubing/well annulus. The well is completed with either a slotted liner or a cemented and perforated casing. The coiled tubing, placed at the farthest end of the well is retrieved gradually at a rate dependent on the injection rate. Both rates are calculated and are contingent upon reservoir and well properties and upon desired stimulation-fluid coverage. The complex phenomenon of acid stimulation involves different rheological properties between acid and the inert fluid, simultaneous mass transfer and reaction kinetics, and for carbonate reservoirs, such instabilities as wormhole growth. Acid-volume distributions along the well are presented for cases with and without coiled tubing. This paper details the procedures for this treatment, discusses hardware configurations, and outlines recommended fluids, additives, and rates.

    Horizontal infill wells in the Lower Lagunillas reservoir of Bloque IV, Lake Maracaibo are being drilled in thin, oil-bearing zones that have been bypassed by gas. Steering the horizontal sections of these wells requires high resolution reservoir models that can be updated during drilling. An example from well VLD-1152 serves to illustrate how these models are generated and used. Resistivity images collected by wireline and logging-while-drilling (LWD) tools in the pilot well formed the basis of prejob, high resolution modeling of the formation properties. 3-D seismic data and data from an offset vertical seismic profile collected in the pilot well provided the structural model. During drilling information from cuttings and LWD tools was used to continuously update these models. After the well had been drilled, analysis of LWD resistivity images provided a detailed model of the relationship between the well trajectory and the dip of the formation. This information is used to improve interpretation of the LWD logs to provide a petrophysical evaluation of the well.

    Since 1995, a large region of Australia has been gripped by the most severe drought in living memory, the so-called ``Big Dry''. The ramifications for affected regions are dire, with acute water shortages for rural and metropolitan areas, record agricultural losses, the drying-out of two of Australia's major river systems and far-reaching ecosystem damage. Yet the drought's origins have remained elusive. For Southeast Australia, we show here that the ``Big Dry'' and other iconic 20th Century droughts, including the Federation Drought (1895-1902) and World War II drought (1937-1945), are driven by Indian Ocean variability, not Pacific Ocean conditions as traditionally assumed. Specifically, a conspicuous absence of Indian Ocean temperature conditions conducive to enhanced tropical moisture transport has deprived southeastern Australia of its normal rainfall quota. In the case of the ``Big Dry'', its unprecedented intensity is also related to recent higher temperatures.

    Trends in precipitation extremes were examined using daily precipitation data from Southeast Asian countries during 1950's to 2000's. Number of wet day, defined by a day with daily precipitation exceeding 1 mm, tends to decrease over these countries, while average precipitation intensity of wet day shows an increasing trend. Heavy precipitation indices, which are defined by precipitation amount and percentile, demonstrate that the number of stations with significant upward trend is larger than that with significant downward trend. Heavy precipitation increases in southern Vietnam, northern part of Myanmar, and the Visayas and Luzon Islands in the Philippines, while heavy precipitation decreases in northern Vietnam. Annual maximum number of consecutive dry days decreases in the region where winter monsoon precipitation dominates. Prolongation of the dry season is suggested in Myanmar.

  3. Permian of Southeast Asia: an overview

    Permian rocks are widely distributed throughout Southeast Asia. Because of the tropical-equatorial climate the rocks are commonly deeply weathered and covered by dense vegetation over much of the region. Elsewhere, Permian rocks are well exposed and easy to access, particularly where limestone outcrops have weathered to form spectacular, castellated, tower karst. Many limestone outcrops, containing abundant fusulinaceans, were early recognized to be of Permian age, but many outcrops without fusulinaceans, erroneously assigned to the Permian, were found subsequently to be of Triassic age, and more careful studies have established the Permian age of rocks of other lithologies. It is now recognized that different depositional environments are represented by the Permian deposits in various parts of the region. Massive limestones, widespread throughout the region, represent extensive carbonate platforms; local occurrences of thick bedded cherts indicate deposition in deep marine environments, coal, bauxite and clastic sediments with vertebrate remains in North Vietnam and Laos indicate deposition in a continental environment, and pebbly mudstones in Myanmar, Peninsular Thailand, northwest Malaysia and Sumatra, are considered to have been formed in a glacial environment. Volcanic rocks are absent in northwest Peninsular Malaysia and Peninsular Thailand, but are extensively developed in North Vietnam, Sumatra, the eastern Malay Peninsula and Timor. Fossils, representing many fossil groups, are often prolific in Permian sediments, with fusulinaceans, for example, occurring in astronomical numbers in many limestone outcrops. Age-diagnostic fossils demonstrate that the whole of the Permian is represented in different areas of Southeast Asia. Fossil faunal and floral assemblages have been used to establish climatic conditions and environments of deposition, to define distinct crustal blocks and to provide the basis for reconstructing the palaeogeography during Permian times.

    This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

    The outreach program for Southeast Asian immigrants, chiefly Cambodians who arrived after 1980, begun by St. Mary Medical CEnter of Long Beach California, called the Southeast Asian Health Project (SEAHP) was evaluated by structured interviews of 199 women. The obstacles to full participation by these Asian immigrants in health care are described at length. They range from illiteracy and abuse in refugee camps to the immense cultural barrier involving philosophy of health to language barriers. The SEAHP Outreach services began with door-to-door canvassing, ads in refugee papers, and meetings in temples. Special educational resource materials were printed covering prenatal care, nutrition, child development, and feeding. Oral classes were held in CAmbodian and Lao with Vietnamese translators, as well as babysitters, transportation, and snacks. Class topics were nutrition, parenting skills, labor and delivery, child development, hygiene, and breast feeding. Training was also given to professional staff. 600 clients in prenatal clinics since 1987, 119 were interviewed by 4 workers fluent in Cambodian and Lao. The women were typical of refugees, only 1/2 were literate in native languages. 49% had delivered babies at home in Asia; 39% had delivered in refugee camp clinics. Women cited several different behaviors as a result of SEAHP classes: intake of milk products, use of food substitutes, food preparation, attendance at regular medical care, child care, and bathing. They said that they felt more comfortable at the clinic, and would recommend that friends go to the clinic for prenatal care. The concept of culture broker, and the role of nurses as culture brokers are discussed.

    Resorption of alveolar bone - a common sequel of tooth loss jeopardizes the functional and esthetic outcome of treatment, especially in the maxillary anterior areas. Therefore, augmentation of deficient alveolar ridges is an important aspect of dental implant therapy. A case of severe maxillary ridge deficiency successfully treated with horizontal ridge augmentation to facilitate implant placement is described. Ridge augmentation was achieved using a combination of autogenous block graft, particulate grafting, and guided bone regeneration (GBR). Follow-up was done next day, after ten days, three months, and six months. Various approaches can be followed in order to achieve an increase in the ridge width. In our case, we used a combination of different techniques for ridge augmentation. A significant improvement in ridge width was noticed at six months thus facilitating the placement of implants.

    2017-03-01

    This study involved the numerical investigation of conjugate natural convection between two horizontal eccentric cylinders. Both cylinders were considered to be isothermal with only the inner cylinder having a finite wall thickness. The momentum and energy equations were discretized using finite volume method and solved by employing SIMPLER algorithm. Numerical results were presented for various solid-fluid conductivity ratios ( KR) and various values of eccentricities in different thickness of inner cylinder wall and also for different angular positions of inner cylinder. From the results, it was observed that in an eccentric case, and for KR < 10, an increase in thickness of inner cylinder wall resulted in a decrease in the average equivalent conductivity coefficient (overline{{K_{eq} }}); however, a KR > 10 value caused an increase in overline{{K_{eq} }}. It was also concluded that in any angular position of inner cylinder, the value of overline{{K_{eq} }} increased with increase in the eccentricity.

    The present study examined intergroup judgments made between four groups of non-meat eaters: health vegetarians; ethical vegetarians; health vegans, and ethical vegans. Consistent with hypotheses based on horizontal hostility and the need to maintain ingroup distinctiveness, ethical vegetarians gave unfavorable evaluations to health vegetarians relative to vegans, especially when the mainstream omnivore group was made salient. Contrary to expectations, vegans gave relatively more favorable evaluations to ethical vegetarians than health vegetarians when mainstream salience was low. This was especially true for vegans who were motivated primarily by ethical concerns. When mainstream salience was high, vegans did not distinguish between the vegetarian subgroups. Results suggest that one’s motives for abstaining from meat often play a larger role in this type of intergroup perceptions than one’s dietary practices. PMID:24809342

    The Halobacteria are a well-studied archaeal class and numerous investigations are showing how their diversity is distributed amongst genomes and geographic locations. Evidence indicates that recombination between species continuously facilitates the arrival of new genes, and within species, it is frequent enough to spread acquired genes amongst all individuals in the population. To create permanent independent diversity and generate new species, barriers to recombination are probably required. The data support an interpretation that rates of evolution (e.g., horizontal gene transfer and mutation) are faster at creating geographically localized variation than dispersal and invasion are at homogenizing genetic differences between locations. Therefore, we suggest that recurrent episodes of dispersal followed by variable periods of endemism break the homogenizing forces of intrapopulation recombination and that this process might be the principal stimulus leading to divergence and speciation in Halobacteria.

    Horizontal gene transfer (HGT) plays an important role in the evolution of life on the Earth. This view is supported by numerous occasions of HGT that are recorded in the genomes of all three domains of living organisms. HGT-mediated rapid evolution is especially noticeable among the Bacteria, which demonstrate formidable adaptability in the face of recent environmental changes imposed by human activities, such as the use of antibiotics, industrial contamination, and intensive agriculture. At the heart of the HGT-driven bacterial evolution and adaptation are highly sophisticated natural genetic engineering tools in the form of a variety of mobile genetic elements (MGEs). The main aim of this review is to give a brief account of the occurrence and diversity of MGEs in natural ecosystems and of the environmental factors that may affect MGE-mediated HGT. PMID:21845185

    It has been suggested that horizontal gene transfer (HGT) is the “essence of phylogeny.” In contrast, much data suggest that this is an exaggeration resulting in part from a reliance on inadequate methods to identify HGT events. In addition, the assumption that HGT is a ubiquitous influence throughout evolution is questionable. Instead, rampant global HGT is likely to have been relevant only to primitive genomes. In modern organisms we suggest that both the range and frequencies of HGT are constrained most often by selective barriers. As a consequence those HGT events that do occur most often have little influence on genome phylogeny. Although HGT does occur with important evolutionary consequences, classical Darwinian lineages seem to be the dominant mode of evolution for modern organisms. PMID:12902542

    1992-01-01

    Ray-trace equations for uniaxial birefringent materials are used here to derive third-order estimates for aberrations that are produced in imaging through uniaxial plates and horizontal-vertical (HV) depolarizers. An HV depolarizer is a spatial pseudodepolarizer; it converts a uniform input polarization state into a continuum of spatially varying polarization states in an output beam. An HV depolarizer consists of two birefringent wedges whose crystal axes are crossed at 90 deg. The interface between the wedges is included, which leads to a spatially varying retardance that provides the spatial pseudodepolarization. In HV depolarizers, spherical aberration, astigmatism, and image doubling are the principal aberrations for on-axis objects. Only spherical aberration occurs in isotropic plates, while the presence of birefringent wedges introduces astigmatism and image doubling. It is shown that image separation is proportional to the magnitude of the retardance variation.

    Post, Richard F.

    2003-12-02

    A passive magnetic bearing is composed of a levitation element and a restorative element. The levitation element is composed of a pair of stationary arcuate ferromagnetic segments located within an annular radial-field magnet array. The magnet array is attached to the inner circumference of a hollow shaft end. An attractive force between the arcuate segments and the magnet array acts vertically to levitate the shaft, and also in a horizontal transverse direction to center the shaft. The restorative element is comprised of an annular Halbach array of magnets and a stationary annular circuit array located within the Halbach array. The Halbach array is attached to the inner circumference of the hollow shaft end. A repulsive force between the Halbach array and the circuit array increases inversely to the radial space between them, and thus acts to restore the shaft to its equilibrium axis of rotation when it is displaced therefrom.

    Horizontal gene transfer (HGT) between species has been a major focus of plant evolutionary research during the past decade. Parasitic plants, which establish a direct connection with their hosts, have provided excellent examples of how these transfers are facilitated via the intimacy of this symbiosis. In particular, phylogenetic studies from diverse clades indicate that parasitic plants represent a rich system for studying this phenomenon. Here, HGT has been shown to be astonishingly high in the mitochondrial genome, and appreciable in the nuclear genome. Although explicit tests remain to be performed, some transgenes have been hypothesized to be functional in their recipient species, thus providing a new perspective on the evolution of novelty in parasitic plants.

    A high speed method for forming ribbon crystal of desired width and thickness is characterized by drawing out the ribbon through a space whose distance is 5.7 times that of the thickness of the grown ribbon. The ribbon is drawn out between the molten body of the lower surface and the tip of the upper surface of the seed crystal and growing crystal. The ribbon growing at the tip of the seed crystal is drawn out horizontally and centrifugally by controlling the amount of cooling and heating. The temperature is maintained about equal to the upper surface of the outlets from which the molten substance is drawn, at least in certain portions of the crucible rim, the rim is elevated to prevent dropping of the molten raw material.

    2017-07-01

    This study presents some FE results regarding the behavior under horizontal loads of two existing masonry towers located in South-East Lombardy, Italy. The towers, albeit unique for geometric and architectural features, show some affinities that justify a comparative analysis, as for instance the location and the similar masonry material. Their structural behavior under horizontal loads is therefore influenced by geometrical issues, such as slenderness, walls thickness, perforations, irregularities, presence of internal vaults, etc., which may be responsible for a peculiar output. The geometry of the towers is deduced from both existing available documentation and in-situ surveys. On the basis of such geometrical data, a detailed 3D realistic mesh is conceived, with a point by point characterization of each single geometric element. The FE models are analyzed under seismic loads acting along geometric axes of the plan section, with non-linear dynamic excitation assumptions. A damage-plasticity material model exhibiting softening in both tension and compression, already available in the commercial code Abaqus, is used for masonry. Non-linear dynamic analyses are performed along both the X and Y directions with a real accelerogram scaled to different peak ground accelerations. Some results presented in this paper show the high vulnerability of ancient masonry towers under horizontal loads.

  1. Vertical and horizontal soil CO2 transport and its exchanges with the atmosphere

    The CO2 efflux from soils to the atmosphere constitutes one of the major fluxes of the terrestrial carbon cycle and is a key determinant for sources and sinks of CO2 in land-atmosphere exchanges. Because of their large global magnitude, even small changes in soil CO2 effluxes directly affect the atmospheric CO2 content. Despite much research, models of soil CO2 efflux rates are highly uncertain, with the positive or negative feedbacks between underground carbon pools and fluxes and their temperature sensitivities in future climate scenarios largely unknown. Now it is necessary to change the point of view regarding CO2 exchange studies from an inappropriately conceived static system in which all respired CO2 is directly emitted by molecular processes to the atmosphere, to a dynamic system with gas transport by three different processes: convection, advection and molecular diffusion. Here we study the effects of wind-induced advection on the soil CO2 molar fraction during two years in a shrubland plateau situated in the Southeast of Spain. A borehole and two subterranean profiles (vertical and horizontal) were installed to study CO2 transport in the soil. Exchanges with the atmosphere were measured by an eddy covariance tower. In the vertical profile, two CO2 sensors (GMP-343, Vaisala) were installed at 0.15m and 1.5m along with soil temperature and humidity probes. The horizontal profile was designed to measure horizontal movements in the soil CO2 molar fraction due to down-gradient CO2 from the plant, where the majority CO2 is produced, towards bare soil. Three CO2 sensors (GMM-222, Vaisala) were installed, the first below plant (under-plant), the second in bare soil separated 25 cm from the first sensor (near-plant) and the third in bare soil at 25 cm from the second sensor (bare soil). The results show how the wind induces the movement of subterranean air masses both horizontally and vertically, affecting atmospheric CO2 exchanges. The eddy covariance tower
