Rapid assessment of trachoma in 9 governorates and Socotra Island in Yemen.  

PubMed

This study described the pattern of trichiasis, active trachoma and trachoma risk factors in 9 governorates of Yemen plus Socotra Island, using a rapid assessment during October and February 2004. A total of 3169 children aged 1-9 years were examined in a central meeting point or at home. Active trachoma was found in a high percentage of children in Al-Jawf, Mareb and Shabwah governorates and the SAFE strategy (Surgery, Antibiotic treatment, Facial cleanliness, Environmental improvement) should be directed toward these governorates. Trichiasis cases were also found in Hadramout and Taiz, suggesting that eyelid surgery should be provided in these governorates. PMID:17333795

Effect of School Based Treatment on the Prevalence of Schistosomiasis in Endemic Area in Yemen  

PubMed Central

Background Schistosomiasis and soil transmitted infection is a major health problem of children from rural areas of developing countries including Yemen. In an attempt to reduce this burden, the Ministry of Public Health and Population in Yemen established in 2002 a programme for Schistosomal, soil transmitted infection control that aimed to reduce morbidity and prevalence rates of Schistosomiasis, and Soil transmitted helminthes to less than 5% by 2015. The study was conducted to assess the current prevalence and intensity of schistosomal infection among schoolchildren in rural areas of the Taiz governorate after 6 years of running National Control Programme. Methods Grade 3 schoolchildren from Shara'b Al-Raona district of Taiz Governorate were examined for infections with Schistosoma mansoni using Modified Kato–Katz method and S. haematobium applying filtration method in 1998/1999, comparing the prevalence and intensity of infection with base line study, which was done 6 years ago. Results The S. mansoni prevalence in the study population was 31%, while the prevalence of S. haematobium was 18.6%. This result considerably is similar to the prevalence of base line study. The intensity of mild, moderate and severe infection for S. mansoni reached to 15.9%, 60.6% & 23.5% respectively. The severity of S. haematobium infection was 68.4%. It was exceptionally found that the prevalence of S. haematobium is increased. Conclusion The high prevalence of schistosomiasis and low effectiveness of control programme against schistosomal infection in the study area demands consideration of alternative treatment approaches.

Healthcare financing in Yemen.  

PubMed

Yemen is a low-middle-income country where more than half of the population live in rural areas and lack access to the most basic health care. At US$40 per capita, Yemen's annual total health expenditure (THE) is among the lowest worldwide. This study analyses the preconditions and options for implementing basic social health protection in Yemen. It reveals a four-tiered healthcare system characterised by high geographic and financial access barriers mainly for the poor. Out-of-pocket payments constitute 55% of THE, and cost-sharing exemption schemes are not well organised. Resource-allocation practices are inequitable because about 30% of THE gets spent on treatment abroad for a small number of patients, mainly from better-off families. Against the background of a lack of social health protection, a series of small-scale and often informal solidarity schemes have developed, and a number of public and private companies have set up health benefit schemes for their employees. Employment-based schemes usually provide reasonable health care at an average annual cost of YR44 000 (US$200) per employee. In contrast, civil servants contribute to a mandatory health-insurance scheme without receiving any additional health benefits in return. A number of options for initiating a pathway towards a universal health-insurance system are discussed. PMID:22532485

Women in Physics in Yemen  

NASA Astrophysics Data System (ADS)

We presents the progress of women in Yemen in various fields of science in general and in physics in particular. Women in Yemen attending universities tend to choose science after medicine. The percentage of women in physics is low compared with those for other departments. As a special case, in Sana'a University the percentage of women in the physics department has increased greatly in the last decade. At the level of teaching staff there are only two females with PhD degrees in the whole of Yemen.

Genetic diversity of Plasmodium falciparum and distribution of drug resistance haplotypes in Yemen  

PubMed Central

Background Despite evident success of malaria control in many sites in the Arabian Peninsula, malaria remains endemic in a few spots, in Yemen and south-west of Saudi Arabia. In addition to local transmission, imported malaria sustains an extra source of parasites that can challenge the strengths of local control strategies. This study examined the genetic diversity of Plasmodium falciparum in Yemen and mutations of drug resistant genes, to elucidate parasite structure and distribution of drug resistance genotypes in the region. Methods Five polymorphic loci (MSP-2, Pfg377 and three microsatellites on chromosome 8) not involved in anti-malarial drug resistance, and four drug resistant genes (pfcrt, pfmdr1, dhfr and dhps) were genotyped in 108 P. falciparum isolates collected in three sites in Yemen: Dhamar, Hodeidah and Taiz. Results High diversity was seen in non-drug genes, pfg377 (He?=?0.66), msp-2 (He?=?0.80) and three microsatellites on chr 8, 7.7 kb (He?=?0.88), 4.3 kb (He?=?0.77) and 0.8 kb (He?=?0.71). There was a high level of mixed-genotype infections (57%), with an average 1.8 genotypes per patient. No linkage disequilibrium was seen between drug resistant genes and the non-drug markers (p?Yemen is indicative of a large parasite reservoir, which represents a challenge to control efforts. The presence of two distinct pfcrt genotype, CVIET and SVMNT, suggests that chloroquine resistance can possibly be related to a migratory path from Africa and Asia. The absence of the triple mutant dhfr genotype (IRN) and dhps mutations supports the use of artesunate?+?sulphadoxine-pyrimethamine as first-line therapy. However, the prevalent pfmdr1 genotype NFSND [21%] has previously been associated with tolerance/resistance response to artemisinin combination therapy (ACT). Regular surveys are, therefore, important to monitor spread of pfmdr1 and dhfr mutations and response to ACT.

Promoting gender parity in basic education: Lessons from a technical cooperation project in Yemen  

NASA Astrophysics Data System (ADS)

Many girls are not sent to school in Yemen, despite basic education being free as well as compulsory for all children aged 6-15. Aiming to improve girls' enrolment by increasing parental and community involvement, the Japan International Cooperation Agency (JICA) offered a technical cooperation project in June 2005 called Broadening Regional Initiative for Developing Girls' Education (BRIDGE). Phase 1 of this project ran for three and a half years, piloting a participatory school management model supported by school grants in six districts of the Taiz Governorate in the Southwest of Yemen. To find out how successful this approach has been in a traditional society, the authors of this paper analysed the gender parity index (GPI) of the project's pilot schools. Based on data collected at three points in time (in the initial and final years of the project, and two years after the project's end), their findings suggest that interventions in school management which strongly emphasise girls' education can be effective in improving gender parity rather quickly, regardless of the schools' initial conditions. However, the authors also observe that the pilot schools' post-project performance in terms of gender parity is mixed. While the local government allocated budgets for school grants to all pilot schools even after the project's end, training and monitoring activities were cut back. The authors further observe that the variation in performance appears to be significantly correlated with school leaders' initial perceptions of gender equality and with the number of female teachers employed. These findings point to the importance of providing schools with continuous long-term guidance and of monitoring those which implement school improvement programmes.

PubMed Central

Objectives The aims of this study are to highlight the clinicopathological features of urinary bladder cancer in Yemen, and to describe the histological grading of urothelial neoplasms according to the World Health Organization and International Society of Urologic pathology (WHO/ISUP 1998) classification. Methods This is a descriptive record-based study of 316 cases of bladder cancer diagnosed by two pathologists at the Department of pathology, Sana'a University from 1st January 2005 to 30th April 2009. The diagnoses were made on hematoxylin and eosin stained sections and categorized according to WHO/ISUP 1998 classification. Results Out of 316 urinary bladder cancers, 248 (78%) were urothelial neoplasms, 53 (17%) were squamous cell carcinoma, 7 (2%) were adenocarcinoma, and 3 (1%) were rhabdomyosarcoma. The remaining cases were metastatic carcinomas (n=3), small cell carcinoma (n=1), and non-Hodgkin's lymphoma (n=1). The urothelial neoplasms observed were carcinoma in situ 4 (2%), papilloma 7 (3%), papillary urothelial neoplasm of low malignant potential 26 (11%), papillary urothelial carcinoma of low grade 107 (43%), papillary urothelial carcinoma of high grade 18 (7%), and non-papillary urothelial carcinoma of high grade 85 (34%), with 60 years mean age for males and 58 years for females; along with a male to female ratio of 4:1. The peak incidence was observed in the 61-70 years age group. Conclusion This study documents a high frequency of urothelial neoplasms, mostly papillary urothelial carcinoma of low grade and non-papillary urothelial carcinoma of high grade with male preponderance and peak incidence in 6th decade of age.

People's Democratic Republic of Yemen.  

PubMed

The population of the People's Democratic Republic of Yemen grew from 992,000 in 1950 to 1.7 million in 1975, and the total fertility rate has remained relatively constant at 7 since 1950. The Government has not adopted a population policy per se, but has included sectoral policies that have implications for the size, growth, composition, and distribution of the population. The Government maintains that population issues should be viewed comprehensively within the framework of economic and social development. Measures to achieve economic growth, combined with the expansion of health, education, cultural, and social services, as well as the eradication of illiteracy and the emancipation of women, are expected to have a major impact on the society's demographic structure. The Government's main concern with regard to population growth is a reduction in morbidity and mortality. The rate of growth is projected to increase from 2.7% in 1980-85 to 2.9 in the year 2000, at which point it should begin to decline. The crude death rate is presently 18.8/1000 and is expected to drop to 13.1/1000 by 2000. Infant mortality stood at 138/1000 in 1980-85. Morbidity and mortality are unacceptably high among infants, children, nomads, and rural residents. Priorities for the health sector include the development and expansion of health services, intensive preventive health care for mothers and children, development of a safe drinking water system, nutrition and health education campaigns, and training of health personnel. Measures that are expected to decrease fertility include family planning education, an expansion of facilities to rural areas, and improvements in the status of women. Family planning services are freely available from maternal and child health centers, mainly in urban areas. A mass literacy campaign seeks to increase the female literacy rate to 90%, and women's participation in wage labor is being encouraged. A further goal of population policy is to modify spatial distribution through rural development and agriculture collectivization. PMID:12267833

Operators in Yemen draw warning from Saudis  

SciTech Connect

This paper reports that foreign oil companies with concessions in northern Yemen have been drawn into a border dispute between Yemen and Saudi Arabia. At least six companies received letters from the Saudi government warning them that steps, as yet undefined, will be taken if exploration extends into disputed areas. A second territorial dispute also appears to be brewing in the region. Iran has ejected United Arab Emirates nationals from the island of Abu Musa in the Persian Gulf, which is jointly administered by Iran and Sharjah, one of the emirates. The U.A.E. government has reported the situation to the Gulf Cooperation Council, triggering a denial from Iran that anyone has been deported from the island.

Determining when corals reproduce has clear management and economic implications. Here we document the reproductive condition of corals in the genus Acropora on the island of Socotra in Yemen during February 2014. Twenty percent of colonies (n = 143) contained mature gametes and 28% had immature gametes indicating that spawning will occur in both February and March in 2014, confirming previous anecdotal reports of coral spawning at this time in Socotra. Acropora typically reproduce in synchrony with many other broadcast spawning scleractinian corals, and we therefore predict that many other species are reproductively active at this time of year.

Outbreak of viral hemorrhagic fever caused by dengue virus type 3 in Al-Mukalla, Yemen  

PubMed Central

Background Investigations were conducted by the authors to explore an outbreak of viral hemorrhagic fever (VHF) reported in 2010 from Al-Mukalla city, the capital of Hadramout in Yemen. Methods From 15–17 June 2010, the outbreak investigation period, specimens were obtained within 7?days after onset of illness of 18 acutely ill patients hospitalized with VHF and 15 household asymptomatic contacts of 6 acute cases. Additionally, 189 stored sera taken from acutely ill patients with suspected VHF hospitalized in the preceding 12?months were obtained from the Ministry of Health of Yemen. Thus, a total of 222 human specimens were collected; 207 specimens from acute cases and 15 specimens from contacts. All samples were tested with RT-PCR for dengue (DENV), Alkhumra (ALKV), Rift Valley Fever (RVFV), Yellow Fever (YFV), and Chikungunya (CHIKV) viruses. Samples were also tested for DENV IgM, IgG, and NS1-antigen. Medical records of patients were reviewed and demographic, clinical, and laboratory data was collected. Results Of 207 patients tested, 181 (87.4%) patients were confirmed to have acute dengue with positive dengue NS1-antigen (97 patients, 46.9%) and/or IgM (163 patients, 78.7%). Of the 181 patients with confirmed dengue, 100 (55.2%) patients were IgG-positive. DENV RNA was detected in 2 (1%) patients with acute symptoms; both samples were molecularly typed as DENV type 3. No other VHF viruses were detected. For the 15 contacts tested, RT-PCR tests for the five viruses were negative, one contact was dengue IgM positive, and another one was dengue IgG positive. Of the 181 confirmed dengue patients, 120 (66.3%) patients were males and the median age was 24?years. The most common manifestations included fever (100%), headache (94.5%), backache (93.4%), malaise (88.4%), arthralgia (85.1%), myalgia (82.3%), bone pain (77.9%), and leukopenia (76.2%). Two (1.1%) patients died. Conclusions DENV-3 was confirmed to be the cause of an outbreak of VHF in Al-Mukalla. It is important to use both IgM and NS1-antigen tests to confirm acute dengue particularly under the adverse field conditions, where proper storage and transportation of specimens are missing, which substantially reduce the sensitivity of the RT-PCR for detecting DENV RNA.

Oral lesions and dental status among institutionalized orphans in Yemen: A matched case-control study  

PubMed Central

Objectives: The aim of this study was to assess the prevalence of oral mucosal lesions (OMLs) and dental caries and to evaluate oral health practices among institutionalized orphan-children in Sana’a city, Yemen. Subjects and Methods: A sample of 202 institutionalized male-orphan-children in the main orphanage in Sana’a city, were matched to 202 non-orphan schoolchildren. Clinical examination included assessment of OMLs based on standard international diagnostic criteria and evaluation of dental status using the Decayed/decayed, Missed/missed and Filled/filled (DMFT/dmft) index according to World Health Organization recommendations. Demographic data and oral hygiene practices were obtained by interviewing each subject using special questionnaire form. Results: Majority of children were in the 12-15 year age group. Nine types of lesions were reported among orphans; the most common lesions were fissured tongue (24.3%), herpes labialis (7.9%) and traumatic ulcers (2.5%). The occurrence of herpes labialis was found to be significantly higher in orphans than in controls (P < 0.01). The prevalence of dental caries was insignificantly lower among the orphans (84.7%) compared with the non-orphans (89.61%; P = 0.136). The mean dmft score was significantly lower in orphans than in controls (2.28 vs. 3.82; P = 0.001). Conclusions: The institutionalized children in this orphanage had a high prevalence of OMLs but low prevalence of dental caries, though they revealed poor oral hygiene practices. Effective oral health promotion strategies need to be implemented to improve the oral health and oral health practices of children living in orphanages.

Structural analysis of a fractured basement reservoir, central Yemen  

NASA Astrophysics Data System (ADS)

The Pan-African Arabian-Nubian Shield (ANS), within which Yemen lies, formed as a result of Neoproterozoic collisional events between c. 870-550 Ma. Several subsequent phases of extension occurred, from the Mesozoic (due to the breakup of Gondwana) to the Recent (forming the Gulf of Aden and the Red Sea). These resulted in the formation of numerous horst- and-graben structures and the development of fractured basement reservoirs in the southeast part of the ANS. Two drill cores from the Mesozoic Marib-Shabwa Basin, central Yemen, penetrated the upper part of the Pan-African basement. The cores show both a lithological and structural inhomogeneity, with variations in extension-related deformation structures such as dilatational breccias, open fractures and closed veins. At least three deformation events have been recognized: D1) Ductile to brittle NW-SE directed faulting during cooling of a granitic pluton. U-Pb zircon ages revealed an upper age limit for granite emplacement at 627±3.5 Ma. As these structures show evidence for ductile deformation, this event must have occurred during the Ediacaran, shortly after intrusion, since Rb/Sr and (U-Th)/He analyses show that subsequent re-heating of the basement did not take place. D2) The development of shallow dipping, NNE-SSW striking extensional faults that formed during the Upper Jurassic, simultaneously with the formation of the Marib-Shabwa Basin. These fractures are regularly cross-cut by D3. D3) Steeply dipping NNE-SSW to ENE-WSW veins that are consistent with the orientation of the opening of the Gulf of Aden. These faults are the youngest structures recognized. The formation of ductile to brittle faults in the granite (D1) resulted in a hydrothermally altered zone ca. 30 cm wide replacing (mainly) plagioclase with predominantly chlorite, as well as kaolinite and heavy element minerals such as pyrite. The alteration- induced porosity has an average value of 20%, indicating that the altered zone is potentially a good fluid-flow pathway and also a suitable reservoir for hydrocarbons. The youngest faults (D3) are often filled with calcite, (saddle) dolomite and pyrite that formed at temperatures between 100 and 150° C. Fluid inclusions within calcite have abundant hydrocarbon-rich components indicating that these veins formed synchronously with hydrocarbon migration. The same minerals were deposited within the ductile to brittle faults within the granite (formed during D1). This resulted in significant porosity reduction, especially in the faults themselves, reducing the fluid flow efficiency within the altered granite, locking up hydrocarbons and reducing the reservoir quality.

Diphtheria: a possible foodborne outbreak in Hodeida, Yemen Arab Republic  

PubMed Central

Between 29 August 1981 and 16 January 1982, an epidemic of diphtheria produced 149 cases in Hodeida, Yemen Arab Republic. The overall attack rate was 11.8 per 10 000; the most frequent victims were males under 5 years of age, with an attack rate of 55.7 per 10 000. Severity of the illness varied inversely with age and the number of previous doses of DPT. A case—control study showed that vaccination with DPT was protective (P = 0.03) with an efficacy of 87.3% (95% confidence interval, 32.2-99.5%) among those who had received 3 or more doses. Risk factors for the development of disease were previous contact with a case (P = 0.002), previous contact with a person having skin disease (P = 0.04), obtaining drinking-water from a wheeled carrier (P = 0.008), and consumption of factory-made yoghurt (P = 0.003). The secondary attack rate among household contacts under 15 years of age was at least 1.3%.

Dengue Outbreak in Hadramout, Yemen, 2010: An Epidemiological Perspective  

PubMed Central

We analyzed surveillance data of a dengue outbreak (2010) reported to the Hadramout Health Office (Yemen) and retrospectively analyzed dengue-related epidemiological and entomological events reported in Hadramout from 2005 to 2009. A total of 630 immunoglobulin M (IgM) -confirmed dengue cases of 982 febrile cases was reported during the period from February to June of 2010; 12 cases died, giving case fatality a rate of 1.9%. Among febrile cases, the highest proportion of dengue cases (37.3%) was reported in the 15- to 24-year-old age group. The overall attack rate was 0.89/1,000. The average number of cases reported by month over the preceding 5-year period compared with the 2010 data is consistent with endemicity of dengue in the region and supports epidemic designation for the dengue activity in 2010. Recognition of endemic dengue transmission and potential for substantial dengue epidemics highlight the need for consistent laboratory-based surveillance that can support prevention and control activities accordingly.

A brief investigation of the surface-water hydrology of Yemen Arab Republic  

USGS Publications Warehouse

Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west. Rainfall is low and seasonal; consequently, most streams (wadis) are ephemeral. The natural flow regimens of many of the smaller wadis are modified by terracing for agriculture. The only streamflow data available in Yemen are short records on four large wadis. A brief field investigation and application of reconnaissance techniques are the bases for the largely qualitative description of the hydrology, and for the proposal to collect streamflow data needed for orderly development of the expanding economy.

Correlating Individual Oligocene Silicic Flood Volcanic Eruptions Across the Conjugate Rifted Margins of Yemen and Ethiopia  

NASA Astrophysics Data System (ADS)

Large-volume silicic pyroclastic volcanism is an important component of the Afro-Arabian Oligocene flood volcanic province and subsequent syn-rift volcanism. It provides ideal marker horizons for correlating individual eruption units within and between Yemen and Ethiopia. The volcano-stratigraphy preserved in Yemen is well-exposed and relatively untectonized. Using detailed stratigraphic and geochemical studies we have reconstructed the complete flood volcanic succession which we use to correlate to the structurally complex Ethiopian margin. For the first time, in situ analysis of Pb isotopes in feldspar and groundmass by laser ablation MC-ICP-MS has enabled correlation of individual ignimbrite units from Yemen to Ethiopia. These correlations are also supported by major, trace and REE geochemistry, Nd isotopic data and 40Ar/39Ar dating studies from Yemen and Ethiopia. Subtle Pb isotopic variations among units reflect differences in crustal contamination by juvenile Pan-African basement (in Oligocene flood volcanic units) or Archaean basement (in syn-rift volcanic units). Differences in 207Pb/206Pb and 208Pb/206Pb between units range from 0.003 to >0.02. We have measured these Pb isotopic ratios to better than +/-0.0009, which is at least a factor of 3 less than the smallest observed inter-unit variation. Variations within individual units sampled from multiple sections ranging from 20 to >100 km apart, are identical within analytical error, demonstrating the lateral homogeneity of units. Preliminary estimates of eruption volumes for individual silicic units in Yemen range from 200 to >1000 km3. Units found in both Yemen and Ethiopia may have total volumes >2000 km3. With 13 major silicic units found in Yemen, which were erupted in less than 2 Ma, this represents one of the largest outpourings of silicic volcanism on Earth. Detailed volcano-stratigraphic correlations allow a more accurate estimation of eruption volumes and possible climatic impact of large-volume silicic pyroclastic volcanism associated with the Afro-Arabian flood volcanic province. In situ Pb isotopes may also be a powerful tool for correlating Neogene silicic ash units in Afar associated with hominid-bearing fossiliferous sediments.

Proposed low-cost premarital screening program for prevention of sickle cell and thalassemia in Yemen  

PubMed Central

In Yemen, the prevalence of sickle cell trait and ?-thalassemia trait are high. The aim of this premarital program is to identify sickle cell and thalassemia carrier couples in Yemen before completing marriages proposal, in order to prevent affected birth. This can be achieved by applying a low-cost premarital screening program using simple blood tests compatible with the limited health resources of the country. If microcytosis or positive sickle cell is found in both or one partner has microcytosis and the other has positive sickle cell, so their children at high risk of having sickle cell or/and thalassemia diseases. Carrier couples will be referred to genetic counseling. The outcomes of this preventive program are predicted to decrease the incidence of affected birth and reduce the health burden of these disorders. The success of this program also requires governmental, educational and religious supports.

Malaria in Egypt, Saudi Arabia and Yemen: a clinical pilot study.  

PubMed

Imported malaria is a health problem and needs continuous monitoring as many clinicians are not aware of it. In Yemen malaria is the main public health problem. Malaria cases were 16 in Almaza Military Fever Hospital, Cairo, 53 in Saudi Hospital at Pilgrimage, Yemen and in Saber Hospital at Aden, Yemen were studied. 9 cases (56.2%) of P. falciparum in Cairo were imported and 7 cases (43.8%) acquired P. vivax locally (October 2003 to July 2004). They were all treated successfully by chloroquine. An imported case (6.3%) died by cerebral malaria due to delayed diagnosis. Five imported cases (31.3%) had severe malaria. In Pilgrimage, an infant (1.9%) had congenital malaria, 17 cases (32.1%) had severe malaria and 2 (3.8%) died by cerebral malaria. 43 patients (81.1%) had P. falciparum and 10 patients (18.9%) had P. vivax. All patients were treated by parenteral or oral quinine. In Aden, one patient (5%) suffered diarrhea without fever, early blood film was negative, and was positive later on. 18 cases (90%) had P. falciparum, 2 (10%) had P. vivax. 4 cases (20%) had severe malaria & a patient (5%) died by cerebral malaria. Patients in Aden severe cases were successfully treated by intramuscular artemether followed by oral Fansidar, and mild ones were treated by oral Quartem. PMID:18383796

Assessment of Gingival Health Status among 5- and 12-Year-Old Children in Yemen: A Cross-Sectional Study  

PubMed Central

Purpose. There are limited data about the gingival health status in Yemeni children. The aim, therefore, was to assess oral hygiene status and prevalence and severity of gingivitis among Yemeni preschool and school children. Materials and Methods. A total of 5396 children were included from 5 representative Yemeni governorates: Sana'a, Hajjah, Hodeida, Hadramaut, and Taiz. Five-year olds (1292) were recruited from private kindergartens while 12-year olds (4104) were selected from public primary schools. Gingival health status was assessed using the plaque index (PI), calculus index (CAI), and gingival index (GI) on the 6 Ramfjord teeth. The latter index was used to categorize gingivitis severity at the subject level. Data were analyzed using simple hypothesis testing, as well as ordinal regression. Results. The 12-year old children had significantly much higher mean PI, CAI, and GI (P < 0.001) with 78.6% presenting with gingivitis and 47.8% with moderate gingivitis. In contrast, the figures were 27.2% and 3.1% in the younger group (P < 0.001). There were significant variations according to gender, area of residence, and governorate. Regression analysis revealed that mean PI (OR = 35), mean CAI (OR = 7.7), male gender (OR = 1.6), living in rural areas (OR = 1.4), and being from Hajjah or Sana'a were independent risk factors of gingivitis severity in the older group. For the 5-year olds, the determinants were mean PI (OR = 122), male gender (OR = 1.4), and living in Sana'a or Taiz. Conclusions. Bad oral hygiene and moderate gingivitis are highly prevalent among Yemeni preschool and school children. Geographical location appeared as important independent risk factors of gingival inflammation.

Data from geologic investigations in the Yemen Arab Republic during 1976  

USGS Publications Warehouse

The results of semiquantitative spectrographic analyses for 31 elements in 126 specimens of rocks from the Yemen Arab Republic, collected mainly during February 1976 from the Precambrian area in the southeastern part of the country, provide background data for use in geochemical evaluation of areas potentially favorable for mineral deposits. Gold and thorium were undetected; the lower limits of determination are 10 parts per million (ppm) and 20 ppm, respectively. For the other elements, the abundances follow geochemical norms for crustal distribution: (1) Fe, Nb, and Zr in Holocene weathering products; (2) Ca and Sr in Pliocene limestone; (3) Mo in Pliocene(?) or Miocene(?) dikes; (4) Be, La, and Sn in Miocene(?) alkalic granite; (5) As, Be, and La in Tertiary and/or Cretaceous felsic tuff; (6) V in Tertiary and/or Cretaceous carbonaceous sedimentary rocks interbedded with volcanic rocks; (7) Be, La, Sn, and Zr in Tertiary and/or Cretaceous undivided volcanics; (8) Sn and W in Precambrian felsite and pegmatite; (9) Co, Cr, Ni, and Ti in Precambrian mafic rocks; (10) Mg and Sr in Precambrian marble and calcsilicate rocks; (11) Y in Precambrilan schist; (12) B and Sc dispersed in rocks of many ages; and (13) Ag, Ba, Bi, Cd, Cu, Mn, Pb, Sb, Sn, and Zn in a hydrothermal replacement deposit in Precambrian sediment. None of the rocks contained as much as 205 ppm equivalent uranium. The highest values for Ag, Cu, Pb, Zn, and Cd were obtained on a sample of hydrothermally altered siltstone not personally collected by the writers. It was said to have come from the Ma'rib area in the eastern part of the Yemen Arab Republic. The source must be studied, because this single sample is high-grade base-metal ore. Among the samples collected by the writers, the economically most significant are altered tuffs, ignimbrites, and felsites exposed between Jibal Hufash and Manakhah on the road from Hudaydah to San'a'. They are strongly anomalous for As and weakly anomalous, variously, for Hg, Mo, and Pb, which elements may constitute an epigenetic dispersion pattern from hidden sulfide deposits. Inasmuch as chalcopyrite and native copper have been reported in the vicinity of Jabal Haraz in the Manakhah area, the rocks of the Yemen Volcanics in this region should be explored for base-metal sulfide deposits. The first results of paleontologic examinations of fossils collected during 1975 and 1976 are presented, as are a list of Landsat images covering the Yemen Arab Republic, and a selected bibliography of reports on geology and the allied sciences relating to the Yemen Arab Republic.

Morphological variation between isolates of the nematode Haemonchus contortus from sheep and goat populations in Malaysia and Yemen.  

PubMed

Haemonchus contortus is a highly pathogenic nematode parasite of sheep and goats. This work was conducted to investigate the population and host variations of the parasitic nematode H. contortus of sheep and goats from Malaysia and Yemen. Eight morphological characters were investigated, namely the total body length, cervical papillae, right spicule, left spicule, right barb, left barb, gubernaculum and cuticular ridge (synlophe) pattern. Statistical analysis showed the presence of morphological variation between populations of H. contortus from Malaysia and Yemen, with minor variation in the synlophe pattern of these isolates. Isolates from each country were grouped together in the scatterplots with no host isolation. Body, cervical papillae and spicule lengths were the most important characters that distinguished between populations of the two countries. This variation between Malaysia and Yemen may be attributed to geographical isolation and the possible presence of a different isolate of this worm in each country. PMID:23176779

Subsidence history, crustal structure, and evolution of the Somaliland-Yemen conjugate margin  

NASA Astrophysics Data System (ADS)

We have used biostratigraphic data from deep exploration wells to determine the tectonic subsidence history of the Somaliland (northwestern Somalia)-Yemen conjugate margin, a poorly known margin in the central part of the Gulf of Aden. Bathymetry and magnetic anomaly data suggest the Gulf of Aden is a young feature that formed following the rifting apart and breakup of the African and Arabian plates ~32 Ma. Our tectonic subsidence data suggest, however, that the present-day Gulf of Aden developed on an earlier Mesozoic rift system. The oldest episode of rifting initiated at ~156 Ma and lasted for ~10 Ma and had a NW-SE trend. We interpret the rift as a late stage event associated with the breakup of Gondwana and the separation of Africa and Madagascar. At ~80 Ma, there is evidence of an intermediate rift event which correlates with a rapid increase in spreading rate on the ridges separating the African and Indian and African and Antarctica plates and a contemporaneous slowing down of Africa's plate motion. The combined effect of all three rifting events has been to thin the crust and upper mantle by up to a factor of 2. The amount of thinning deduced from the wells is in accord with the crustal structure inferred from available seismic refraction data and process-oriented gravity and flexure modeling. The margin is asymmetric with a steeper gradient in the Moho on the Yemen side than the Somaliland side. The main discrepancy is on the Yemen side where the gravity-derived Moho is 10 km deeper than the well-derived Moho. We attribute the discrepancy to the addition of material at the base of the crust since rifting, possibly magma sourced from the Afar plume.

Bathymetry and magnetic anomaly data suggest the Gulf of Aden is a young feature that formed following the break up and rifting apart of the African and Arabian plates ~32 Ma. Our tectonic subsidence data suggest, however, that the present-day Gulf of Aden developed on an earlier Mesozoic rift system. The oldest rift, which has a NW-SE trend, initiated ~156 Ma and lasted for ~10 Ma. We interpret the rift as a late stage event associated with the break-up of Gondwanaland and the separation of Africa and Madagascar. At ~80 Ma, there is evidence of another rift event which we associate with the separation of Madagascar and India, an increase in spreading rate in the Indian Ocean and the emplacement of the Deccan large igneous province. The combined effect of all three rifting events has been to thin the crust and upper mantle by up to a factor of 2. The amount of thinning deduced from the wells is in accord with the crustal structure inferred from available seismic refraction data and process-oriented gravity modelling and suggests that the margin is asymmetric with a steeper Moho gradient on the Yemen side than the Somaliland side. The main discrepancy is on the Yemen side where the gravity-derived Moho is deeper than the well-derived Moho. We attribute the discrepancy to the addition of material at the base of the crust since rifting, possibly magma sourced to the Afar plume. We do not require, however, a contribution of dynamic topography associated with the plume to explain the tectonic subsidence data.

Prevalence and Associated Factors of Schistosomiasis among Children in Yemen: Implications for an Effective Control Programme  

PubMed Central

Background Schistosomiasis, one of the most prevalent neglected tropical diseases, is a life-threatening public health problem in Yemen especially in rural communities. This cross-sectional study aims to determine the prevalence and associated risk factors of schistosomiasis among children in rural Yemen. Methods/Findings Urine and faecal samples were collected from 400 children. Urine samples were examined using filtration technique for the presence of Schistosoma haematobium eggs while faecal samples were examined using formalin-ether concentration and Kato Katz techniques for the presence of S. mansoni. Demographic, socioeconomic and environmental information were collected via a validated questionnaire. Overall, 31.8% of the participants were found to be positive for schistosomiasis; 23.8% were infected with S. haematobium and 9.3% were infected with S. mansoni. Moreover, 39.5% of the participants were anaemic whereas 9.5% had hepatosplenomegaly. The prevalence of schistosomiasis was significantly higher among children aged >10 years compared to those aged ?10 years (P<0.05). Multivariate analysis confirmed that presence of other infected family member (P<0.001), low household monthly income (P?=?0.003), using unsafe sources for drinking water (P?=?0.003), living nearby stream/spring (P?=?0.006) and living nearby pool/pond (P?=?0.002) were the key factors significantly associated with schistosomiasis among these children. Conclusions/Significance This study reveals that schistosomiasis is still highly prevalent in Yemen. These findings support an urgent need to start an integrated, targeted and effective schistosomiasis control programme with a mission to move towards the elimination phase. Besides periodic drug distribution, health education and community mobilisation, provision of clean and safe drinking water, introduction of proper sanitation are imperative among these communities in order to curtail the transmission and morbidity caused by schistosomiasis. Screening and treating other infected family members should also be adopted by the public health authorities in combating this infection in these communities.

A qualitative appraisal of the hydrology of the Yemen Arab Republic from Landsat images  

USGS Publications Warehouse

Six series of Landsat-1 and Landsat-2 images taken between 1972 and 1976 were analyzed to describe the flow regimens of streams and the regional distribution of vegetation in the Yemen Arab Republic. The findings provide a factual basis for planning a surface-water data collection program, and for preparing maps of plant distribution and agricultural land use. They lay the foundation for modernized water development, for effecting a program of country-wide water management. The work was undertaken as part of the program of the U.S. Agency for International Development with the cooperation of the Yemen Mineral and Petroleum Authority, Ministry of Economy. A false-color composite mosaic of the nine images which cover the country was prepared using Landsat 1 images taken at relatively low sun-angle in winter 1972-73. Catchment areas and the major drainage basins of the country were delineated on this mosaic. In order of increasing water availability, the four catchment areas of the YAR are: Ar Rub al Khali, Wadi Jawf (Arabian Sea), Red Sea, and Gulf of Aden. Most streams are ephemeral. No lakes were detected during the period under investigation, but sebkhas--salt flats or low salt-encrusted plains--are common along the Red Sea coast. In spite of resolution and scale constraints, streamflow was interpreted as perennial or intermittent, wherever it could be detected on several Landsat images covering the same scene at seasonal or yearly intervals. Much of the land under cultivation is restricted to valley floors, and to valley slopes and irrigated terraces adjacent to stream channels. Little or no vegetation could be detected over large regions of the Yemen Arab Republic. (USGS)

Prevalence of Obesity in Patients With Type 2 Diabetes Mellitus in Yemen  

PubMed Central

Background: Obesity is common in type 2 diabetic patients in some of the Middle Eastern countries, which are amongst the countries with highest rates of diabetes mellitus and obesity. Objectives: We conducted this study to assess the prevalence of obesity in Yemeni patients with type 2 diabetes mellitus. Patients and Methods: Body mass index (BMI) of patients with type 2 diabetes mellitus who were 25-years-old or older was measured during their first visit to an endocrinology and diabetes clinic in Sana’a, Yemen over a 4-year period from May 2007 to May 2011. Results: The BMI was measured in 1640 patients (721 males and 919 females) who attended the clinic. According to the measured BMI, 328 (45.5%), 314 (43.5%), 79 (11%) of the male patients were non-obese (BMI < 25 kg/m2), overweight (BMI 25-29.9 kg/m2), and obese (BMI ? 30 kg/m2), respectively. On the other hand, 256 (28%), 369 (40.0%), and 294 (32%) of the female patients were non-obese (BMI < 25 kg/m2), overweight (BMI 25-29.9 kg/m2), and obese (BMI ? 30 kg/m2), respectively. Conclusions: The prevalence of obesity in patients with type 2 diabetes mellitus in Yemen is high with respect to the Yemeni population, especially in females.

The Role of Demand Factors in Utilization of Professional Care during Childbirth: Perspectives from Yemen  

PubMed Central

Background. Utilization of professional care during childbirth by women in low-income countries is important for the progress towards MDG?5. In Yemen, home births have decreased minimally during the past decades. Objective. The study investigates the influence of socio-demographic, birth outcome and demand factors on women's future preference of a home or institutional childbirth. Method. We interviewed 220 women with childbirth experience in urban/rural Yemen. We performed bivariate chi-square tests and multiple logistic regression analysis. A multistage sampling process was used. Results. The issues of own choice, birth support and birth complications were the most important for women's preference of future location of childbirth. Women who had previously been able to follow their own individual choice regarding birth attendance and/or location of childbirth were six times more likely to plan a future childbirth in the same location and women who received birth support four times more likely. Birth complications were associated with a 2.5-fold decrease in likelihood. Conclusions. To offer women with institutional childbirth access to birth support is crucial in attracting women to professional care during childbirth. Yemeni women's low utilization of modern delivery care should be seen in the context of women's low autonomy and status.

An analytical framework for capacity development in EIA - The case of Yemen  

SciTech Connect

Most countries worldwide nowadays apply Environmental Assessment (EA) as an ex ante tool to evaluate environmental impacts of policies, plans, programmes, and projects. However, the application and performance of EA differ significantly. Scientific analysis of how EA performs mainly focuses on two levels: the micro (or project) level and the macro (or system) level. Macro level analysis usually focuses on institutions for EA and the organisation of stakeholder interaction in EA. This article proposes a more comprehensive framework for analysing EA systems that combines other approaches with a capacity approach and an explicit consideration of the context in which EA systems are developed and performed. In order to illustrate the value of our framework, we apply it to the Republic of Yemen, where over the last decades many EA capacity development programmes have been executed; however, EA performance has not substantially improved. The Yemen case study illustrates that the capacity development approach allows an understanding of the historical process, the stakeholders, the knowledge component, and the material and technical aspects of EA, but perhaps more important is a systemic understanding of the outcomes: problems are not isolated, but influence and even maintain each other. In addition, by taking into account the context characteristics, our framework allows for the assessment of the feasibility of capacity development programmes that aim at improving EA system performance.

Early Precambrian gneiss terranes and Pan-African island arcs in Yemen: Crustal accretion of the eastern Arabian Shield  

NASA Astrophysics Data System (ADS)

Within the Precambrian of Yemen, we have identified four gneiss terranes and two island-arc terranes on the basis of existing literature, mapping, and our own field observations, together with new Sm-Nd isotopic data. The two western gneiss terranes can be correlated with well-documented terranes (Asir and Afif) in Saudi Arabia. To the east of these, the Abas and Al-Mahfid gneiss terranes yield Sm-Nd model ages (tDM) of 1.7 2.3 Ga and 1.3 2.7 Ga, respectively, and cannot be correlated with any documented terranes in Saudi Arabia. These two terranes are separated by a Pan-African island-arc terrane that has been obducted onto one or both of the gneiss terranes, and a second arc bounds the Al-Mahfid gneiss terrane to the east. Our discovery of extensive Proterozoic to late Archean gneisses in Yemen provides important constraints upon the much-discussed tectonic framework of northeast Gondwana and the rate of Pan-African crustal growth. The terranes in Yemen may be correlated with comparable terranes on the eastern margin of the Arabian Shield and in northern Somalia. Thus Yemen provides a link between the arc collage of the Arabian Shield and the gneissic Mozambique belt of East Africa.

Fracture and vein characterization of a crystalline basement reservoir, central Yemen  

NASA Astrophysics Data System (ADS)

The country of Yemen is located in the south-western part of the Arabian plate. The Pan-African basement found in western and central Yemen is highly deformed during the Proterozoic eon and is part of the Arabian-Nubian shield ANS (670-540Ma). This ANS is a result of the amalgamation of high-grade gneiss terranes and low-grade island arcs. The development of an extensive horst-and-graben system related to the breakup of Gondwana in the Mesozoic, has reactivated the Pan-African basement along NW-SE trending normal faults. As a result, younger Meosozoic marls, sandstones, clastics and limestones are unconformably overlying the basement. Some of these formations act as a source and/or reservoir for hydrocarbons. Due to fracturing of the basement, hydrocarbons have migrated horizontally into the basement, causing the crystalline basement to be a potential hydrocarbon reservoir. Unfortunately, little is known about the Pan-African basement in Central Yemen and due its potential as a reservoir, the deformation and oil migration history (with a main focus on the fracturing and veining history) of the basement is investigated in high detail. Representative samples are taken from 2 different wells from the Habban Field reservoir, located approximately 320 ESE of Sana'a. These samples are analysed using e.g. the Optical Microscope, SEM, EDX and CL, but also by doing Rb-Sr age dating, isotope analysis and fluid inclusion analysis. In well 1, the only lithology present is an altered gneiss with relative large (<5 cm diameter) multi-mineralic veins. In well 3, quartzite (top), gneiss (middle) and quartz porphyry's (middle) are intruded by a so called "younger" granitoid body (592.6±4.1Ma). All lithologies record polyphase systems of mineral veins. Pyrite and saddle dolomite in these veins have euhedral shapes, which means that they have grown in open cavities. Calcite is the youngest mineral in these veins, closing the vein and aborting the fluid flow. Fluid inclusions inside the calcite record homogenization temperatures (Th) of approximately 120°C with a maximum of 140°C. This is thought to be approximately equal to the calcite formation temperature. Also the euhedral saddle dolomite is thought to be formed at approximately these temperatures. Migration and precipitation of the vein systems represents an important process in the formation of the crystalline basement hydrocarbon reservoir.

Causes of Chronic Renal Failure in Hemodialysis Unit: a single center experience in Yemen.  

PubMed

This cross-sectional study was carried out to determine the possible causes of chronic renal failure (CRF) in Ibn Sina Teaching Hospital (ISTH) in Hadramout, Yemen. Fifty-one CRF patients (29 men and 22 women) on regular hemodialysis were included in the study. Glomerulonephritis (25.4%) was the commonest cause of CRF, followed by obstructive nephropathy (13.7%), hypertension (11.8%), pyelonephrits (11.8%), diabetic nephropathy (7.8%), arthritis, malaria, vasculitis and postpartum hemorrhage (5.9% each) and the least common one was Alport's syndrome (3.9%). There were more men than women (57% and 43%, respectively). The mean age range of the patients was 42 years. More patients were the from coast of Mukalla than from the valley and desert (59% and 41%) respectively. PMID:17297542

Epidemiology of hypertension in Yemen: effects of urbanization and geographical area  

PubMed Central

Although globalization can contribute to increased blood pressure by spreading unhealthy behaviors, it also provides powerful means to tackle hypertension. The dissemination of information about and advice on cardiovascular prevention and facilitated contact with health services are valuable resources. To investigate the effects of urbanization, geographical area, and air temperature on hypertension burden and kidney damage, a survey was performed in 2008 with a door-to-door approach among urban and rural adult dwellers of three geographic areas (capital, inland, coast) of Yemen. Subjects (n=10?242) received two visits several days apart to confirm the diagnosis of hypertension. Proteinuria (dipstick test ?+1) was used as a marker of kidney damage. Prevalence rates were weighted to represent the Yemen population aged 15–69 years in 2008. Rates of hypertension and proteinuria progressively increased from the capital (6.4% 95% confidence level (CI) 5.8–7.0 and 5.1% 4.4–5.9, respectively), to inland areas (7.9% 7.0–8.7 and 6.1% 5.1–7.1), to the coastal area (10.1% 8.9–11.4 and 8.9% 7.3–10.4). When compared with urban dwellers, rural dwellers had similar hypertension prevalence (adjusted odds ratios (ORs) 1.03; 95% CI 0.91–1.17) but higher proteinuria rates (adjusted ORs 1.55; 1.31–1.85). Overall, home temperature was associated with a lower hypertension rate (adjusted OR 0.98; 0.96–0.99). This large population study reveals that the highest burden of hypertension and kidney damage is detectable in remote areas of the country.

Thermal history of the Pan-African basement under the Jurassic Marib-Shabwa Basin, Yemen  

NASA Astrophysics Data System (ADS)

Pan-African tectonism within the Arabian Nubian Shield in Yemen is very poorly known. New drill-cores from the Marib-Shabwa Basin (Habban oil field) from central Yemen penetrated 600 m into the pre-Jurassic crystalline basement, providing a unique opportunity to extend our understanding of Pan-African events in Yemen. The cores were obtained some 80 km NE of the exposure limit of the Al Bayda Terrane, which lies SE of Sana'a. This terrane, which has no direct correlative in the ANS further north in Saudi Arabia, comprises deformed greenschist facies acid to basic volcanic rocks later witnessing acid to basic magmatism and has been previously interpreted as a Pan-African island arc complex with a basement component. Ophiolite fragments are common, both within the terrane and at its margins (sutures). To the north lies the Abas Gneiss Terrane and to the south the Al Mahfid Gneiss Terrane; both consist of older pre-Pan-African crystalline basement rocks. Geochemistry of a red, undeformed granite from the drill core indicates an A-type composition. LA-ICPMS U-Pb analysis of granite zircons gave two concordant age populations: 628.3 ± 3.1 Ma (large & small zircons) and 604.9 ± 2.0 Ma (intermediate sized zircons). The former age is interpreted as the time of crystallization, within the range of other A-type Younger Granites in the ANS, and the latter age as constraining lower temperature dissolution-reprecipitation of zircon, due to hydrothermal fluids or melt remobilization. Nd Tdm model ages for two granite samples from the drill core both gave ages of 1.24 Ga, within the range of the Al Bayda Terrane (1.2-2.5 Ga) and outside the range of the adjacent Palaeoproterozoic gneissic terranes (1.7-2.3 Ga, Abas Gneiss Terrane; 1.8-3.0 Ga, Al Mahfid Gneiss Terrane). Thus it seems certain that the Al Bayda Terrane extends at least 80 km to the NE of its present surface exposure. Rb-Sr biotite ages from the granite indicate closure through ~300°C at 593 Ma, indicating fast cooling either as a result of near-surface conditions of emplacement or rapid exhumation. Zircon (U-Th)/He cooling ages (~180°C) are constrained to the Early Carboniferous. The youngest (Cenozoic) set of veins contain pyrite, (saddle) dolomite and calcite. Pyrite sulphur isotopes, the occurrence of saddle dolomite and calcite fluid inclusions provide strong evidence that the Pan-African basement was not re-heated to above 150°C after the last stage of deformation; this places some constraint on the thickness of the sedimentary cover that was deposited.

Remote village survey for agents causing hepatosplenic disease in the Republic of Yemen.  

PubMed

The objective of this study was to epidemiologically describe potential infectious agents among rural people in the Republic of Yemen. This would aid clinicians in designing empirical therapy and public health officials in planning disease prevention. We sought to examine evidence for the geographical distribution of pathogens causing human hepatic and splenic disease among villagers and domestic animals living in three remote areas with differing altitudes. In June 1992, a cross-sectional survey was conducted at three survey sites of differing altitudes: 3080, 1440 and 250 m above sea level. Questionnaires, parasitic and serological tests were administered to 627 human volunteers. Additionally 317 domestic animals were studied. Malaria, schistosomiasis, and hepatitis B and C infections were found to be likely causes of human hepatic or splenic disease. Additionally, evidence of human and animal infections with the agents of brucellosis and Q fever was found: IgG antibodies against hepatitis E virus were discovered in two (2.0%) of the 100 volunteers. The prevalence of markers for human and animal disease was often lowest at the village of highest elevation, suggesting that increasing altitude, as a surrogate or a true independent risk factor, was protective against infection with the agents studied.

Geothermal prospecting by geochemical methods in the Quaternary volcanic province of Dhamar (central Yemen)  

NASA Astrophysics Data System (ADS)

This abstract deals with geothermal prospecting carried out in the active volcanic area of Dhamar, which is located almost in the centre of the main Oligo-Miocene basaltic trap plateau of Yemen. This Quaternary volcanic field hosts two active volcanoes: Al Lisi and Isbil, the latter having erupted a basaltic lava flow in 1937. By applying geochemical and thermometric techniques in domestic wells producing from a shallow unconfined aquifer that is prevalently hosted within the Quaternary volcanics, a thermal anomaly associated with the Quaternary volcanic activity was well delineated. Although the aquifer has a Ca-Na-HCO3 composition, that is typical of shallow aquifers, there are several anomalies in the thermal area compared to typical aquifers: the pH is lower and the calculated partial pressure of CO2 in solution, electrical conductivity, salinity and fluoride ion concentration are higher. Such chemical anomalies are not generated by the rising and/or mixing of deep hydrothermal components into the aquifer, but rather produced by enhanced water-rock interaction processes resulting from the higher temperature of the aquifer. The application of calculations based on the likely temperature of rainfall in the area and the depth and temperature of individual wells, the local thermal gradients in the area have been calculated. The thermal gradient varies from 41 °C/km at the periphery of the thermal anomaly to more than 250 °C/km, within an extensive area (exceeding 200 km2) where the gradient is greater than 100 °C/km.

Obesity, overweight and underweight among adults in an urban community in Yemen.  

PubMed

High body mass index (BMI) is an important risk factor for morbidity and mortality, while low BMI is an indicator of undernutrition; both may be concerns in low-income countries. This cross-sectional, primary-care based study aimed to measure the sex and age-specific mean BMI and estimate the prevalence of obesity, overweight and underweight among adults in an urban community in Sana'a, Yemen. A total of 2500 subjects (919 males and 1581 females) were recruited in 2006. The crude mean BMI for all ages was significantly higher in females [23.9 (SD 5.1) kg/m2] than males [21.8 (SD 8.9) kg/m2]. The mean BMI trend was associated with age, with a peak in the age group 35-44 years. Calculated prevalence showed 18.0% of males and 14.6% of females were overweight (BMI > or = 25 kg/m2) and 2.5% of males and 12.4% of females were obese (BMI > or = 30 kg/m2). In contrast a substantial number of subjects were underweight (BMI <18.5 kg/m2): 20.1% of males and 14.6% of females. PMID:23301392

A middle Eocene mesoeucrocodylian (Crocodyliformes) from the Kaninah Formation, Republic of Yemen  

NASA Astrophysics Data System (ADS)

During the Cenozoic, the Arabian Plate separated from continental Africa and assumed a closer geographical relationship with Eurasia. As such, the vertebrate fossil record of the Arabian Peninsula has great potential for documenting faunal interchanges that occurred as a result of such tectonic events, with a shift from a primarily Afro-Arabian fauna in the Palaeogene to a more cosmopolitan fauna in the Neogene. Understanding of the sequence and timing of this faunal interchange has long been hampered by a lack of palaeontological data. Recently recovered fossils from the Middle Eocene Kaninah Formation of Yemen constitute the earliest Palaeogene record of continental vertebrates from the Arabian Peninsula, thereby offering a rare glimpse at the region's post- -Cretaceous fauna. Here we describe fossil materials from the Kaninah Formation, a collection of dental and postcranial elements representing a mesoeucrocodylian crocodyliform of unclear affinities. The specimen exhibits ziphodont tooth morphology along with a biserial paravertebral shield and polygonal gastral osteoderms, consistent with certain mesoeucrocodylians (e.g., ziphodontan notosuchians). Yet the associated fragmentary anterior caudal vertebra, although badly abraded, preserves morphology suggestive of procoely. This vertebral type in combination with the dental and osteoderm morphology is much more taxonomically restrictive and consistent with the suite of characters exhibited by atoposaurids, a finding that would significantly extend that clade through the Cretaceous/Palaeogene boundary. Alternatively, given the relative paucity of information from the region during the Palaeogene, the combination of characteristics of the Kaninah crocodyliform may reflect a novel or poorly known form exhibiting previously unrecognised character mosaicism. We take a conservative approach, and refer the Kaninah specimen to Mesoeucrocodylia, Atoposauridae (?) pending discovery of more complete material. New fossils recovered from the Kaninah Formation raise unanticipated questions about the longevity of Mesozoic clades, underscoring the role that the region may play in revealing novel occurrences, relictual forms, and evidence of faunal dispersals from this critical interval in vertebrate evolutionary history.

Point Prevalence of Pseudoexfoliation Syndrome in Patients Scheduled for Cataract Surgery in Eye Camps in Yemen  

PubMed Central

Purpose: To study the point prevalence of pseudoexfoliation syndrome (PXS) among Yemeni patients in different governorates with age-related cataract scheduled for surgery. Settings: Eye camps organized by the Nibras Health Society to perform cataract surgeries during the years 2002-2006. All patients aged 40 years and above were included in the study. Materials and Methods: A total of 2535 eyes of 2535 patients from 13 governorates, scheduled for cataract surgery in eye camps, were included. All eyes underwent complete eye examination before the surgery and were evaluated for the signs of pseudoexfoliation material in the pupil, iris and lens capsule on dilated slit lamp examination. Results: The study found 495 of the 2535 eyes (19.53%) with PXS with males more commonly affected than females (55.2 and 44.8%, respectively). The mean age of patients with PXS was 66.2 years while it was 64.6 years in non-PXS patients. The prevalence of pseudoexfoliation syndrome increased with age (10.1% in the age group of 41-50 years that increased to 28.8% in the age group of more than 81 years old). The rate of PXS detection in camps in 13 governorates ranged from 13.33 to 24.22% with an overall rate of 19.53%. The lowest rate was noticed in Sana'a and the highest in Al-Dhale governorate. Conclusion: This pilot study confirms that PXS was common in patients undergoing cataract surgery in Yemen with an increased detection rate with age. This study also highlights the prevalence of an ocular disease that is associated with systemic and ocular complications; however, further studies based on population studies are needed.

Qualitative study on the Community Perception of the Integrated Management of Childhood Illness (IMCI) Implementation in Lahej, Yemen  

PubMed Central

Objectives: This qualitative study was aimed at exploring the perceptions of community leaders and mothers about health services and community actions pertaining to child health in Lahej, Yemen since the Implementation of Integrated Management of Childhood Illnesses (IMCI) in 2003. Methods: Face-to-face, semi-structured, in-depth interviews were conducted with six community leaders and seven mothers in 2007 in the three districts of Lahej Governorate, Yemen, that are implementing IMCI. Results: Neither group was aware of IMCI, but had “positive perception to the services.” Community leaders expressed “uncertainty about the role of health committees and community participation,” and said, “people can contribute in different ways” and “health authorities must play a more active role.” The mothers emphasised, “poor livelihood and environmental conditions” and “salient counselling messages not received.” Conclusion: The pressing needs for effective community-IMCI is obvious owing to the appalling toll on child health of unfavourable livelihood and environmental conditions and disorganised community initiatives. Thus, for effective IMCI implementation, governmental support needs to be strengthened.

Regional differences in the distribution of the sub-Saharan, West Eurasian, and South Asian mtDNA lineages in Yemen.  

PubMed

Despite its key location for population movements out of and back into Africa, Yemen has not yet been sampled on a regional level for an investigation of sub-Saharan, West Eurasian, and South Asian genetic contributions. In this study, we present mitochondrial DNA (mtDNA) data for regionally distinct Yemeni populations that reveal different distributions of mtDNA lineages. An extensive database of mtDNA sequences from North and East African, Middle Eastern and Indian populations was analyzed to provide a context for the regional Yemeni mtDNA datasets. The groups of western Yemen appear to be most closely related to Middle Eastern and North African populations, while the eastern Yemeni population from Hadramawt is most closely related to East Africa. Furthermore, haplotype matches with Africa are almost exclusively confined to West Eurasian R0a haplogroup in southwestern Yemen, although more sub-Saharan L-type matches appear in more northern Yemeni populations. In fact, Yemeni populations have the highest frequency of R0a haplotypes detected to date, thus Yemen or southern Arabia may be the site of the initial expansion of this haplogroup. Whereas two variants of the sub-Saharan haplogroup M1 were detected only in southwestern Yemen close to the Bab el-Mandeb Strait, different non-African M haplotypes were detected at low frequencies (approximately 2%) in western parts of the country and at a higher frequency (7.5%) in the Hadramawt. We conclude that the Yemeni gene pool is highly stratified both regionally and temporally and that it has received West Eurasian, Northeast African, and South Asian gene flow. PMID:18257024

Genetic variation and phylogeography of central Asian and other house mice, including a major new mitochondrial lineage in Yemen.  

PubMed Central

The mitochondrial DNA (mtDNA) control region and flanking tRNAs were sequenced from 76 mice collected at 60 localities extending from Egypt through Turkey, Yemen, Iran, Afghanistan, Pakistan, and Nepal to eastern Asia. Segments of the Y chromosome and of a processed p53 pseudogene (Psip53) were amplified from many of these mice and from others collected elsewhere in Eurasia and North Africa. The 251 mtDNA types, including 54 new ones reported here, now identified from commensal house mice (Mus musculus group) by sequencing this segment can be organized into four major lineages-domesticus, musculus, castaneus, and a new lineage found in Yemen. Evolutionary tree analysis suggested the domesticus mtDNAs as the sister group to the other three commensal mtDNA lineages and the Yemeni mtDNAs as the next oldest lineage. Using this tree and the phylogeographic approach, we derived a new model for the origin and radiation of commensal house mice whose main features are an origin in west-central Asia (within the present-day range of M. domesticus) and the sequential spreading of mice first to the southern Arabian Peninsula, thence eastward and northward into south-central Asia, and later from south-central Asia to north-central Asia (and thence into most of northern Eurasia) and to southeastern Asia. Y chromosomes with and without an 18-bp deletion in the Zfy-2 gene were detected among mice from Iran and Afghanistan, while only undeleted Ys were found in Turkey, Yemen, Pakistan, and Nepal. Polymorphism for the presence of a Psip53 was observed in Georgia, Iran, Turkmenistan, Afghanistan, and Pakistan. Sequencing of a 128-bp Psip53 segment from 79 commensal mice revealed 12 variable sites and implicated >/=14 alleles. The allele that appeared to be phylogenetically ancestral was widespread, and the greatest diversity was observed in Turkey, Afghanistan, Pakistan, and Nepal. Two mice provided evidence for a second Psip53 locus in some commensal populations.

40Ar/39Ar dating of mineral separates and whole-rock (WR) samples has established that basaltic continental flood volcanism (CFV) began between 30.9 and 29.2 Ma in northwestern and southwestern Yemen, respectively. Rhyolitic volcanism commenced at 29.0-29.3 Ma throughout Yemen. Lower basaltic lavas were erupted every 10-100 kyr, whereas upper bimodal volcanic units were erupted every 100-500 kyr, which reflects generation of rhyolitic magmas from basalts that resided for longer periods in lithospheric magma chambers than during the early phase of exclusively mafic magmatism. The youngest dated flood volcanic units were erupted between 26.9 and 26.5 Ma throughout Yemen. The duration of preserved CFV defined by 40Ar/39Ar dating (4.4 myr) contrasts with the wide range of WR K?Ar dates previously obtained in Yemen (> 50 myr). 40Ar/39Ar step-heating studies of WR samples has shown that this discrepancy is due to the disturbed Ar systematics of volcanic samples. Most samples have experienced post-crystallization loss of radiogenic Ar and/or contain excess Ar, with only ca. 25% of the WR K?Ar dates within 1-2 myr of true crystallization ages. WR K?Ar data can be screened for reliability using the radiogenic Ar yield and 40K/36Ar ratio, which reflect the Ar retentivity of the sample, the likelihood that alteration has disturbed a sample's Ar systematics, and the susceptibility of the sample to a finite amount of Ar loss or the presence of a finite amount of excess Ar. Examination of existing WR K?Ar data in the Ethiopian part of this flood volcanic province, using these parameters, suggests that much of these data are also misleading. Two phases of flood volcanism are inferred in Ethiopia and Eritrea at 38-30 Ma and ca. 20 Ma. The older phase is equivalent to that in Yemen, and is consistent with the progression in basal volcanic ages obtained in Yemen moving from north to south. The younger phase is related to the onset of upper crustal extension and incipient Red Sea-Gulf of Aden rifting. The sequence of events — surface uplift (?), flood magmatism and subsequent upper crustal extension — in Yemen is consistent with the involvement of a mantle plume at the Afro-Arabian tripe junction. However, the overall eruption rate for this flood volcanic province is only 0.03 km 3/yr, much slower than that postulated for other plume-related provinces such as the Deccan or Siberian Traps, but perhaps comparable to the Paraná-Etendeka province, which also contains significant amounts of rhyolitic volcanic products like those of Yemen-Ethiopia. The highly variable eruption rates in individual provinces must reflect the very different character of individual plumes, or the control of lithospheric structure and plate tectonic stresses on the surface manifestations of plumes. The long duration of CFV and large amounts of rhyolitic volcanism at the Afro-Arabian triple junction may be attributed to the relatively slow separation of the African and Arabian plates compared with, for example, the rifting of India and the Deccan Traps.

Invincible Cities  

NSDL National Science Digital Library

Throughout history, cities have risen and fallen from prominence, and in recent times more attention has been paid to why this ebb and flow persists across the centuries. Documenting this process has increasingly been the province of historians, archaeologists, city planners, sociologists, and of course, photographers. Many photographers have been very interested in the world of post-industrial urban decay, and Camilo Jose Vergara is one of the best. With financial support from the Ford Foundation, this website brings together VergaraâÂÂs photographic record of the cities of Camden, New Jersey and Richmond, California in exquisite geographic and visual detail. First-time visitors will want to read through the introduction to the project offered by Vergara, and then perhaps click on the question mark on the homepage for a brief primer on how to use the user interface for each city. At that point, visitors shouldnâÂÂt be afraid to look over both cities, as they can zoom in and out around a number of interesting locales, including abandoned factories, old piers, and gated communities. Short of wandering through these cities in a peripatetic fashion, this website serves as an interesting introduction to some overlooked aspects of urbanity.

Contamination and melt aggregation processes in continental flood basalts: constraints from melt inclusions in Oligocene basalts from Yemen  

NASA Astrophysics Data System (ADS)

Melt inclusions from Oligocene continental flood basalts (CFB) erupted in Yemen provide unique insight into the timing and nature of the processes that lead to crustal contamination and melt aggregation in CFB magmas. Large variations in trace element indices that are sensitive to the degree and composition of assimilated crustal material (e.g. K 2O=0.20-1.94 wt%, Ba=13-543 ppm, K/Nb=128-1603, Ba/Th=9-303) are evident in many inclusions, even where these derive from the same host lava, and reflect the complexity of the processes that lead to contamination within individual CFB melting and melt-transport systems. The compositions of melt inclusions relate to differences in the degree of contamination, but in addition require that there is substantial heterogeneity in the composition of the contaminant material itself. Many inclusions also appear to contain more primitive melts than typical Yemen CFB lava compositions, and as such would be highly sensitive to addition of crustal materials. Overall melt inclusions provide a markedly better record of the diversity of melt compositions present within given CFB magma systems than the bulk compositions of erupted lavas. Highly contaminated melts (with K/Nb and Ba/Nb up to 957 and 22, respectively) trapped within fosterite-rich olivines (Fo 85-90) require very high rates of assimilation relative to crystal fractionation, with Ma/ Mc values (the mass ratio of assimilated to crystallized material)?1. Such rapid assimilation may reflect decoupling of heat and mass transfer at the margins of larger magma chambers, within feeder dyke complexes, or at other sites where primitive magma is juxtaposed against wall-rocks that are already heated to temperatures near, or above, their solidus. In addition, relatively little assimilation appears to have occurred after crystallization of the phases that host melt inclusions, consistent with a thermal link between assimilation and phenocryst formation. Melt inclusions also show trace element variations related to mantle source compositions and mantle melting processes. Two inclusions with unusually Sr-rich and rare earth element-poor compositions are similar to those recognized from Mauna Loa, Hawaii, and may be related to melting of recycled gabbroic material within the upwelling Afar plume. In addition, many melt inclusions with crustally contaminated compositions also show large variations in trace element ratios that are essentially insensitive to crustal contamination (e.g. Zr/Y=2-10) but are fractionated during progressive partial melting within an upwelling mantle column. The presence of both mantle and crustal-derived trace element signatures in the same inclusions demonstrates that melt transport systems in Yemen CFB were capable of transporting compositionally distinct melt batches, without complete mixing, through the asthenospheric and lithospheric mantle until final mixing and aggregation (and contamination) within crustal magma reservoirs. Thus, regardless of contamination, the ultimate compositions of many CFB lavas may be determined by magma mixing within the crust, rather than representing primitive compositions derived directly from the mantle.

Specific activities of natural rocks and soils at quaternary intraplate volcanism north of Sana'a, Yemen  

PubMed Central

The level of natural radioactivity in rocks and soil of 32 samples collected from locations at North Sana?a in Yemen was measured. Concentrations of radionuclides in rocks and soils samples were determined by gamma-ray spectrometer using high purity germanium (HPGe) detector with specially designed shield. The average radioactivity concentrations of 226Ra, 232Th, 40K were determined and expressed in Bq/kg. The results showed that these radionuclides were present in concentrations of 21.79 ± 3.1, 19.5 ± 2.6 and 399.3 ± 16 Bq/kg, respectively, for rocks. For soil, the corresponding values were 48.2 ± 4.4, 41.7 ± 4.5 and 939.1 ± 36 Bq/kg, respectively. Also, the radiological hazard of the natural radionuclide content, radium equivalent activity, total dose rates, external hazard index and gamma activity concentration index of the (rocks/soils) samples in the area under consideration were calculated. The dose rates at 1 m above the ground from terrestrial sources were 38.39 and 86.89 nGy/h for rocks and surface soil, respectively, which present no significant health hazards to humans.

Heavy metal concentrations in marine green, brown, and red seaweeds from coastal waters of Yemen, the Gulf of Aden  

NASA Astrophysics Data System (ADS)

The purpose of this study was to investigate the concentration levels of heavy metals in different species of the main three marine algal divisions from the Gulf of Aden coastal waters, Yemen. The divisions included Chlorophyta—green plants ( Halimeda tuna, Rhizoclonium kochiamum, Caldophora koiei, Enteromorpha compressa, and Caulerpa racemosa species), Phaeophyta—brown seaweeds ( Padina boryana, Turbinaria elatensis, Sargassum binderi, Cystoseira myrica, and Sargassum boveanum species), and Rhodophyta—red seaweeds ( Hypnea cornuta, Champia parvula, Galaxaura marginate, Laurencia paniculata, Gracilaria foliifere, and species). The heavy metals, which included cadmium (Cd), cobalt (Co), copper (Cu), chromium (Cr), Iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), zinc (Zn), and vanadium (V) were measured by Atomic Absorption Spectrophotometer (AAs). The concentrations of heavy metals in all algal species are in the order of Fe >> Cu > Mn > Cr > Zn > Ni > Pb > Cd > V > Co. The results also showed that the uptake of heavy metals by different marine algal divisions was in the order of Chlorophyta > Phaeophyta > Rhodophyta. These heavy metals were several order of magnitude higher than the concentrations of the same metals in seawater. This indicates that marine alga progressively uptake heavy metals from seawater.

Reasons For Not Performing Keratorefractive Surgery in Patients Seeking Refractive Surgery in a Hospital-Based Cohort in "Yemen"  

PubMed Central

Background: To determine and analyze the reasons why keratorefractive surgery, laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) were not performed in patients who presented for refractive surgery consultation. Materials and Methods: A retrospective observational study was performed between January 2006 and December 2007 in the Yemen Magrabi Hospital. The case records of 2,091 consecutive new patients who presented for refractive surgery were reviewed. Information from the pre-operative ophthalmic examination, such as refractive error, corneal topography and visual acuity, were analyzed. The reasons for not performing LASIK and PRK in the cases that were rejected were recorded and analyzed. Results: In this cohort, 1,660 (79.4%) patients were advised to have LASIK or PRK from the 2,091 patients examined. LASIK and PRK were not advised in 431 (21%) patients. The most common reasons for not performing the surgery were high myopia >-11.00 Diopters (19%), keratoconus (18%), suboptimal central corneal thickness (15%), cataract (12%) and keratoconus suspect (forme fruste keratoconus) (10%). Conclusion: Patients who requested keratorefractive surgery have a variety of problems and warrant comprehensive attention to selection criteria on the part of the surgeon. Corneal topographies and pachymetry of refractive surgery candidates need to be read cautiously. High-refractive error, keratoconus and insufficient corneal thickness were found to be the leading reasons for not performing keratorefractive surgery in this study.

Possible Ancient Anthrosols Near Lost City of Ubar Site in Oman  

NASA Technical Reports Server (NTRS)

During mapping for the Wadi al Jubal Archaeological Project in Yemen, USGS Geologists Overstreet and Grolier mapped "anthrosols of pre-Islaniic age" east of the Marib dam site (15D 24M N, 45D 18M E). These soils were the result of agriculture supported by irrigation enabled by water impounded by the dam, areas which were abandoned after dam failure. During analysis of Landsat Thematic Mapper satellite images of Yemen and Oman for the Mahra Archaeological Project, we noted that these anthrosols had a distinctive image expression. Based on other remote sensing research and laboratory spectroscopy, we think that the distinctive image signature is due to low reflectivity in Landsat band 7 resulting from relatively high concentrations of gypsum in the anthrosols. Many anthrosol sites were noted, most, but not all, of them previously documented. Undocumented possible anthrosol sites include an area east of Shisr in Oman, the archaeological site discovered by us to be responsible for some features of the "Lost City of Ubar" legends. Included in legendary accounts of the Ubar region are reports of fertile oases, and "areas that have known the plow". Based on demonstrated reliability of aspects of carefully interpreted legendary accounts, we postulate that we may have located the area of desert agriculture that may have existed to support the frankincense caravansary of Ubar. The possible anthrosol area is located at approximately 18D 10M N, 53D 54M E, and will be the subject of study in a future expedition.

City 2020+  

NASA Astrophysics Data System (ADS)

This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to several public transport units running all across the city. This is accompanied by an analysis of probability density functions (PDF) for heat waves based on recent climate data and climate projections. A dense net of 40 PM measurement sites is operated in order to obtain the spatial pattern of PM concentration as depending on meteorological condition and location. It is lined out how this climate related sub-projects interact with investigations on social networks, governance issues, buildings structure development and health outcome. Related to the later the chemical composition of PM is analyzed in more detail and related to the spatial patterns of health deficiencies. At a later stage City2020+ will propose new strategies based on cooperation from the fields of medicine, geography, sociology, history, civil engineering, and architecture for adapting the city for future needs. The Project CITY 2020+ is part of the interdisciplinary Project House HumTec (Human Sciences and Technology) at RWTH Aachen University funded by the Excellence Initiative of the German federal and state governments through the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG).

Decline of Supportive Attitudes among Husbands toward Female Genital Mutilation and Its Association to Those Practices in Yemen  

PubMed Central

Objectives To elucidate the attitudes of women and their husband’s towards female genital mutilation (FGM) and their associations with the continuation of FGM upon their daughters. Methods Subjects were 10,345 (in 1997) and 11,252 (in 2003) ever married women aged 15 to 49 years from the Yemen Demographic Health Surveys. Performances of FGM on the most-recently-born daughters were investigated. Attitudes of women and their husbands were assessed by their opinions on the continuation of FGM. The association between the attitudes of women and their husbands and performance of FGM on the most-recently-born daughters were investigated after adjusting for age and education of the women. Findings The percentage among the most-recently-born daughters who received FGM of women who had undergone FGM declined from 61.9% in 1997 to 56.5% in 2003 (p<0.001). The percentages of women who had undergone FGM and who supported the continuation of FGM and of husbands who also supported its continuation decreased from 78.2% and 60.1% in 1997 to 70.9% and 49.5% in 2003, respectively (both p<0.001). When the women or the husbands did not agree with FGM, it was less likely to be performed on their daughter than when the women or the husbands agreed in 1997 (odds ratio=0.11, 95% confidence interval 0.07-0.16 and odds ratio=0.07, 95% confidence interval 0.04-0.12, respectively) and in 2003 (odds ratio=0.12, 95% confidence interval 0.09-0.16 and odds ratio=0.11, 95% confidence interval 0.07-0.16, respectively). Conclusion Non-supportive attitudes of women and their husbands towards the continuation of FGM have become common and were associated with their decision not to perform FGM upon their daughters.

Nucleotide sequence of the 3' terminal region of the genome of four lettuce mosaic virus isolates from Greece and Yemen.  

PubMed

Lettuce mosaic virus (LMV) is an economically important Potyvirus causing a severe disease of commercial lettuce crops. Based on molecular data, three phylogenetic groups of isolates have previously been discriminated, reflecting their geographical origin (Western Europe-California, Greece, or Yemen). Sequence information for the entire coat protein domain was only available for one of the Western Europe-California phylogenetic group. We have now sequenced the 3' terminal region of the genome LMV-Gr4, -Gr5 and -GrB, isolates which belong to the Greek phylogenetic group and of LMV-Yar, the sole known representative of the third LMV phylogenetic group. The region sequenced encodes the last 62 amino-acids of the polymerase and the entire coat protein of the four isolates, plus the 3' non-translated region of LMV-Gr5 and -Yar. The Greek and Yemenite isolates studied are all very aggressive on lettuce, are able to overcome the resistance genes mo1(1) and mo1(2) and belong to the two phylogenetic groups which have so far been only partially characterised. As for other Potyviruses, the core and the C-terminal regions of the coat protein are highly conserved among all isolates whereas the N-terminus is more variable. No amino acid change in the coat protein or carboxy-terminal part of the polymerase could be related to the resistance-breaking properties of the isolates analysed. The sequences obtained provide the basis for the rapid typing of LMV isolates using the restriction pattern of segments of cDNA amplified by PCR. PMID:10486115

This paper organizes a discussion of the costs and benefits of cities around the question: Are cities becoming obsolete? While minimizing transport costs for manufactured goods no longer justifies the existence of cities, they still facilitate the division of labor and the flow of ideas. Cities' higher housing, commuting, and pollution costs seem stable over time. Only the costs associated

The Suitability of P. falciparum Merozoite Surface Proteins 1 and 2 as Genetic Markers for In Vivo Drug Trials in Yemen  

PubMed Central

Background The accuracy of the conclusions from in vivo efficacy anti-malarial drug trials depends on distinguishing between recrudescences and re-infections which is accomplished by genotyping genes coding P. falciparum merozoite surface 1 (MSP1) and MSP2. However, the reliability of the PCR analysis depends on the genetic markers’ allelic diversity and variant frequency. In this study the genetic diversity of the genes coding for MSP1 and MSP2 was obtained for P. falciparum parasites circulating in Yemen. Methods Blood samples were collected from 511 patients with fever and screened for malaria parasites using Giemsa-stained blood films. A total 74 samples were infected with P. falciparum, and the genetic diversity was assessed by nested PCR targeting Pfmsp1 (Block2) and Pfmsp2 (block 3). Results Overall, 58%, 28% and 54% of the isolates harboured parasites of the Pfmsp1 K1, MAD20 and RO33 allelic families, and 55% and 89% harboured those of the Pfmsp2 FC27 and 3D7 allelic families, respectively. For both genetic makers, the multiplicity of the infection (MOI) was significantly higher in the isolates from the foothills/coastland areas as compared to those from the highland (P<0.05). Pfmsp2 had higher number of distinct allelic variants than Pfmsp1 (20 vs 11). The expected heterozygosity (HE) for Pfmsp1 and Pfmsp2 were 0.82 and 0.94, respectively. Nonetheless, a bias in the frequency distribution of the Pfmsp1 allelic variants was noted from all areas, and of those of Pfmsp2 in the samples collected from the highland areas. Conclusions Significant differences in the complexity and allelic diversity of Pfmsp1 and Pfmsp2 genes between areas probably reflect differences in the intensity of malaria transmission. The biased distribution of allelic variants suggests that in Yemen Pfmsp1 should not be used for PCR correction of in vivo clinical trials outcomes, and that caution should be exercised when employing Pfmsp2.

Remote sensing and GIS application for assessment of land suitability potential for agriculture in the IBB governorate, the Republic of Yemen.  

PubMed

In the present study, an assessment of land suitability potential for agriculture in the study area of IBB governorate, Republic of Yemen has been conducted through close examination of the indicators of land characteristics and qualities. The objective of this study is to evaluate the available land resource and produce the potential map of the study area. Remote sensing data help in mapping land resources, especially in mountainous areas where accessibility is limited. Satellite imagery data used for this study includes data from multi-temporal Landsat TM which dated June 2001. The parameters taken into consideration were 16 thematic maps i.e., slope, DEM, rainfall, soil, land use, land degradation as well as land characteristics maps. Satellite image of the study area has been classified for land use, land degradation and soil maps preparation, while topo sheet and ancillary data have been used for slope and DEM maps and soil properties determination. The land potential of the study area was categorized as very high, high, moderate, low and very low by adopting the logical criteria. These categories were arrived at by integrating the various layers with corresponding weights in a Geographical Information System (GIS). The study demonstrates that the study area can be categorized into spatially distributed agriculture potential zones based on the soil properties, terrain characteristics and analyzing present land use. This approach has the potential as a useful tool for guiding policy decision on sustainable land resource management. PMID:21313888

Mapping of lithologic and structural units using multispectral imagery. [Afar-Triangle/Ethiopia and adjacent areas (Ethiopian Plateau, Somali Plateau, and parts of Yemen and Saudi Arabia)  

NASA Technical Reports Server (NTRS)

The author has identified the following significant results. ERTS-1 MSS imagery covering the Afar-Triangle/Ethiopia and adjacent regions (Ethiopian Plateau, Somali Plateau, and parts of Yemen and Saudi Arabi) was applied to the mapping of lithologic and structural units of the test area at a scale 1:1,000,000. Results of the geological evaluation of the ERTS-1 imagery of the Afar have proven the usefullness of this type of satellite data for regional geological mapping. Evaluation of the ERTS images also resulted in new aspects of the structural setting and tectonic development of the Afar-Triangle, where three large rift systems, the oceanic rifts of the Red Sea and Gulf of Aden and the continental East African rift system, seem to meet each other. Surface structures mapped by ERTS do not indicate that the oceanic rift of the Gulf of Aden (Sheba Ridge) continues into the area of continental crust west of the Gulf of Tadjura. ERTS data show that the Wonji fault belt of the African rift system does not enter or cut through the central Afar. The Aysha-Horst is not a Horst but an autochthonous spur of the Somali Plateau.

Childhood very severe pneumonia and meningitisrelated hospitalization and death in Yemen, before and after introduction of H. influenzae type b (Hib) vaccine.  

PubMed

Haemophilus influenzae type b (Hib) vaccine was included in the Yemen immunization programme in 2005. This study compared the rates of very severe pneumonia and all-cause meningitis hospitalization and death, before and after introduction of conjugate Hib vaccine, and reports the results of the 2010 bacterial meningitis surveillance. A retrospective analysis was made of data collected for 2000-2010 for all children aged 2-60 months in the main children's hospital in Sana'a. Compared with the pre-Hib vaccination period, the post-Hib period showed significant and impressive reductions in the rates of hospitalization and death for all-cause meningitis. However, hospitalization and death for very severe pneumonia improved only modestly, and there was evidence of a decreasing but non-significant trend indicting that very severe pneumonia was a non-specific endpoint with multi-etiologies (both viral and bacterial). Very severe pneumonia remains the leading cause of severe morbidity and death for young children, particularly those aged < 12 months. PMID:25023770

Inequality and City Size*  

PubMed Central

Between 1979 and 2007 a strong positive monotonic relationship between wage inequality and city size has developed. This paper investigates the links between this emergent city size inequality premium and the contemporaneous nationwide increase in wage inequality. After controlling for the skill composition of the workforce across cities of different sizes, we show that at least 23 percent of the overall increase in the variance of log hourly wages in the United States from 1979 to 2007 is explained by the more rapid growth in the variance of log wages in larger locations relative to smaller locations. This influence occurred throughout the wage distribution and was most prevalent during the 1990s. More rapid growth in within skill group inequality in larger cities has been by far the most important force driving these city size specific patterns in the data. Differences in the industrial composition of cities of different sizes explain up to one-third of this city size effect. These results suggest an important role for agglomeration economies in generating changes in the wage structure during the study period.

Prevalence of Coronary Risk Factors, Clinical Presentation, and Complications in Acute Coronary Syndrome Patients Living at High vs Low Altitudes in Yemen  

PubMed Central

Background A comparative retrospective study was performed to compare the distribution of risk factors and complications in patients with acute coronary syndrome (ACS) at high-altitude vs low-altitude areas in Yemen. Methods The records of 768 patients from Sana'a (high altitude) and Aden (low altitude) were reviewed. Risk factors assessed were age, hypertension, diabetes mellitus, hyperlipidemia, cigarette smoking, and reported history and family history of coronary artery disease (CAD). Complications of ACS of interest were heart failure, arrhythmias, cerebrovascular accident (CVA), and death. Results The mean age of ACS patients at high altitude was significantly lower than those at low altitude (55.3 years [SD = 8.2] vs 56.8 years [SD = 7.1]; P = .007). History of hyperlipidemia was significantly higher in high-altitude patients than in low-altitude patients (49.2% vs 38.3%; odds ratio [OR] = 1.563; P = .002). Reported history of CAD was also significantly higher at higher altitudes (16.7% vs 9.4%; OR = 1.933; P = .003). Previous history of diabetes mellitus and tobacco smoking was slightly higher with borderline significance. Hypertension and reported family history of CAD were comparable among high- and low-altitude patients. In terms of in-hospital complications, CVAs were significantly higher in high-altitude patients than in low-altitude patients (7.8% vs 4.4%; P = .0001). Heart failure, arrhythmias, and death rates were comparable in both groups of patients. Wall motion abnormalities were comparable, whereas the ejection fraction was lower in the high-altitude patients (49.8% [SD = 16.08] vs 54.8% [SD = 16.23]; P = .0001). Conclusions ACS occurs at a younger age at high altitudes. Patients who live in high-altitude regions are also more likely to have hyperlipidemia and a previous history of CAD. Stroke and reduced left ventricular ejection fraction (LVEF) occur more commonly in high-altitude ACS patients. High altitude may generally be a risk factor for ACS.

'This diarrhoea is not a disease ...' local illness concepts and their effects on mothers' health seeking behaviour: a qualitative study, Shuhair, Yemen  

PubMed Central

Background Globally, about seven million children under the age of five died in 2011. Local illness concepts are thought to be related to inappropriate health-seeking behaviour, and therefore, lead to child mortality. The aim of this study was to contribute to the definition of common local illness concepts with their effects on health-seeking behaviour for common childhood illnesses. Methods A qualitative focus group study was conducted between April 1 and 6, 2013. Participants were drawn purposefully from the vaccination unit at Shuhair Health Centre in Yemen. Four focus group discussions were conducted. The total number of participants was 31 mothers with at least one child under the age of five with a history of fever, diarrhoea, cough, or difficulty breathing during the 14 days preceding the study. Data was collected and analysed using micro-interlocutor analysis. Results The mean age of the participants was 31 years (SD?±?4). There was remarkable concordance in local illness concepts across the focus groups. During focus group discussions, six local illness concepts (Senoon, lafkha, halib, didan, raqaba, and ayn) were mentioned. Local illness concepts determined the type of treatment. Most of these illnesses were not treated medically. Lafkha, halib, raqaba, and ayn were always classified as “not for medical treatment”, whereas senoon and didan as sometimes “not for medical treatment”. For medical symptoms, i.e. fever, diarrhoea, cough, and difficulty breathing, medical therapy was usually an option; these were classified as never or sometimes “not for medical treatment”. Mothers trust in traditional medicine and believe that it is always beneficial and never harmful. The participants do not disclose traditional medicine use with their doctors because doctors oppose these practices and are not open enough to these types of treatment. Conclusions Local illness concepts for common child illnesses are widespread, and they determine the type of treatment used. Interventions to improve children’s health should use local illness concepts to educate parents. Traditional medicine as a treatment option in primary care should be considered.

Universities Scale Like Cities  

PubMed Central

Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the ‘gross university income’ in terms of total number of citations over ‘size’ in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities -the top-100 European universities- we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

Ultrafine particles in cities.  

PubMed

Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in individual cities, but an integrated evaluation of emissions and population exposure is still lacking. Our analysis suggests that the average exposure to outdoor UFPs in Asian cities is about four-times larger than that in European cities but impacts on human health are largely unknown. This article reviews some fundamental drivers of UFP emissions and dispersion, and highlights unresolved challenges, as well as recommendations to ensure sustainable urban development whilst minimising any possible adverse health impacts.

Industrial Development in Cities  

Microsoft Academic Search

This paper uses data for eight manufacturing industries to test for and characterize dynamic production externalities in cities. The authors find evidence of both Marshall-Arrow-Romer (MAR) externalities, which are associated with past own industry employment concentration, and Jacobs externalities, which are associated with past diversity of local total employment. For mature capital goods industries, there is evidence of MAR externalities

Sinking coastal cities  

NASA Astrophysics Data System (ADS)

In many coastal and delta cities land subsidence now exceeds absolute sea level rise up to a factor of ten. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Land subsidence increases flood vulnerability (frequency, inundation depth and duration of floods), with floods causing major economic damage and loss of lives. In addition, differential land movement causes significant economic losses in the form of structural damage and high maintenance costs. This effects roads and transportation networks, hydraulic infrastructure - such as river embankments, sluice gates, flood barriers and pumping stations -, sewage systems, buildings and foundations. The total damage worldwide is estimated at billions of dollars annually. Excessive groundwater extraction after rapid urbanization and population growth is the main cause of severe land subsidence. In addition, coastal cities are often faced with larger natural subsidence, as they are built on thick sequences of soft soil. Because of ongoing urbanization and population growth in delta areas, in particular in coastal megacities, there is, and will be, more economic development in subsidence-prone areas. The impacts of subsidence are further exacerbated by extreme weather events (short term) and rising sea levels (long term).Consequently, detrimental impacts will increase in the near future, making it necessary to address subsidence related problems now. Subsidence is an issue that involves many policy fields, complex technical aspects and governance embedment. There is a need for an integrated approach in order to manage subsidence and to develop appropriate strategies and measures that are effective and efficient on both the short and long term. Urban (ground)water management, adaptive flood risk management and related spatial planning strategies are just examples of the options available. A major rethink is needed to deal with the 'hidden' but urgent threat of subsidence. As subsidence is spatially different and can be caused by multi processes, an assessment of subsidence in delta cities needs to answer questions such as: what are the main causes, how much is the current subsidence rate and what are future scenarios (and interaction with other major environmental issues), where are the vulnerable areas, what are the impacts and risks, how can adverse impacts can be mitigated or compensated for, and who is involved and responsible to act? In this study a quick-assessment of subsidence is performed on the following mega-cities: Jakarta, Ho Chi Minh City, Dhaka, New Orleans and Bangkok. Results of these case studies will be presented and compared, and a (generic) approach how to deal with subsidence in current and future subsidence-prone areas is provided.

Micromorphology of two prehistoric ritual burials from Yemen, and considerations on methodological aspects of sampling the burial matrix - work in progress  

NASA Astrophysics Data System (ADS)

Introduction In the central area of Yemen, two burial sites placed high in the crevices of vertical cliff face of Cretaceous sandstone (Tawilah Group) provided evidence of human remains and yielded burial soils. Radiocarbon dating indicated c.2500-2900 years BP for the burials. In other local comparable sites the deep horizontal crevices yielded Bronze Age human remains, in exceptional state of preservation Questions: What was the nature of the burial matrix? Are other human influences superimposed on the soils derived from it? Is it simply decomposed crevice rock, scraped together at the time of burial, or the result of a more complex burial practice? Such questions are also relevant to a variety of other burials of different periods and world regions. Methods Seven matrix samples from Cliff Burials (A) Talan (Layers 4,10,12,14,18,20 and 22, from top to bottom) and (B) Shiban Kawkaban (Layer 1 and 9) were analysed with micromorphology, supplemented by SEM microprobe, X-ray diffraction, gas chromatography/mass spectrometry. Results Cliff Burial Site Talan. The presence of cholesterol was confirmed in the lower sample. The second layer contained darker earth with fibrous plant material. A hard calcareous upper capping contrasted with the other levels of matrix, and it displayed a highly birefingent material with a significant component of uric acid. The other levels had variable organic content and plant inclusions, and possibly pollen. In Layer 10, aromatic acids indicative of balsam and sugar markers suggested plant gum. Cholesterol was the major sterol in Layers 10 and 22, but whilst in Layer 10 its oxidation products were present and cholestanol was abundant as normally in soils, it was only a minor component of Layer 22 where, rather, a significant amount of coprostanol indicated faecal input, and cholesterol oxidation products were absent. Cliff Burial Site Shiban Kawkaban. Although no stratification was visible to the naked eye, variation was observed at a micromorphological level. Layer 1 included mineral, bone, plant and soil-like fragments, with leaf and woody tissue, including vascular parts and seeds. Layer 9 included plant tissue, hair, seeds and some fly puparia. Comments Layering of the burial matrix in the Yemeni burials was unexpected and the burial matrix in one case was very clearly not the result of natural soil forming processes within the rock crevice. In Burial Site A the hard upper capping contained uric acid-rich deposits embedding organic tissue. This sample could possibly represent an intentional ‘plaster layer' including plant, hair and seed fragments. The abundant cholesterol confirms an animal/human origin within the matrix of Layers 10 and 22, and the stanol and bile acid distributions unequivocally confirm a human origin, despite the lack of any physical human remains. Microprobe analysis indicated that the hard cup of Burial 1 contained K, Si, Al, Cu, Mg, S, Fe and Na with amounts fluctuating relatively to depth. No special significance can be placed on the differences. This study calls attention to a neglected aspect of burial archaeology: grave infillings can no longer be assumed to be simply the return of material removed for the burial, but may be influenced by other factors. Through micromorphology, decomposed wood, shroud or other textiles or skins and hair can be detected and, if local rituals influenced the way materials were returned into the grave, then this also deserves investigation. A new ERC-funded project (Title: "Interred with their bones", acronym: "InterArChive") tackles these issues (please see separate poster).

An analysis framework for characterizing and explaining development of EIA legislation in developing countries-Illustrated for Georgia, Ghana and Yemen  

SciTech Connect

Actors in the field of international development co-operation supporting the development of EIA legislation in developing countries often do not achieve the results envisaged. The performance of EIA in these countries often remains weak. One reason, we assume, is that often those actors support the establishment of overly ambitious EIA legislation that cannot achieve its objectives in the light of constraining contexts. To provide more effective support we need to better understand the enabling and constraining contextual factors that influence the development of EIA legislation and to which support actors should align itself. In this article a new analysis framework for classifying, characterizing and explaining the development of EIA legislation is described, measured in terms of ambition levels. Ambitions are defined as intentions the EIA authorities aim to fulfill, expressed in formal EIA legislation. Three country cases, Yemen, Georgia and Ghana are used to illustrate the usefulness of our framework and as a first test to refine the framework. We have formulated the following five hypotheses that complement and refine our analysis framework. One, EIA legislation may develop multilinearly in terms of ambition levels. Two, ambitions in EIA legislation seem to be influenced to a great extent by the power and capacity of, on the one hand, the environmental authorities supporting EIA and, on the other hand, the sector authorities hindering the development of EIA. Three, the political system is the most important context factor influencing the rules of policy-making and the power of the different actors involved. Four, the importance of context factors on the development of ambitions is dependent on the phase of EIA system development. Five, some ambitions seem to be influenced by particular factors; for instance the ambitions for the object of study seem to be influenced by the level of environmental awareness of the sector ministries and parliament. The analysis framework may also assist actors involved in the development of EIA legislation in setting ambitions for EIA legislation that are feasible within the context in which it will be developed and implemented. Application of a country-specific EIA model would seem to be the preferred model to develop EIA legislation because by taking capacities of actors and context factors as a starting point, it offers more potential to well-performing EIA systems. - Highlights: Black-Right-Pointing-Pointer EIA systems develop from less to high ambitious and sometimes vice versa. Black-Right-Pointing-Pointer Ambitions in EIA legislation are determined by the capacity of environment- and sector authority. Black-Right-Pointing-Pointer The political system is the most important context factor explaining the ambitions of an EIA system. Black-Right-Pointing-Pointer An analysis framework developed to measure EIA system ambitions might help to setambitions.

Large cities are less green  

NASA Astrophysics Data System (ADS)

We study how urban quality evolves as a result of carbon dioxide emissions as urban agglomerations grow. We employ a bottom-up approach combining two unprecedented microscopic data on population and carbon dioxide emissions in the continental US. We first aggregate settlements that are close to each other into cities using the City Clustering Algorithm (CCA) defining cities beyond the administrative boundaries. Then, we use data on CO2 emissions at a fine geographic scale to determine the total emissions of each city. We find a superlinear scaling behavior, expressed by a power-law, between CO2 emissions and city population with average allometric exponent ? = 1.46 across all cities in the US. This result suggests that the high productivity of large cities is done at the expense of a proportionally larger amount of emissions compared to small cities. Furthermore, our results are substantially different from those obtained by the standard administrative definition of cities, i.e. Metropolitan Statistical Area (MSA). Specifically, MSAs display isometric scaling emissions and we argue that this discrepancy is due to the overestimation of MSA areas. The results suggest that allometric studies based on administrative boundaries to define cities may suffer from endogeneity bias.

Securing water for the cities.  

PubMed

Many cities in developing countries have grown so much that they can no longer provide adequate, sustainable water. Over pumping in Dakar and Mexico City has forced those cities to obtain water from ever more distant sources. In Dakar, the result has been saltwater intrusion. Overpumping has caused Mexico City to sink, in some areas by as much as 9 m, resulting in serious damage to buildings and sewage and drainage pipes. Other cities facing similar water problems are coastal cities in Peru (e.g., Lima), La Rioja and Catamarca in Argentina, cities in Northern Mexico, and cities in dry areas of Africa. For some cities, the problem is not so much ever more distant water supplies but insufficient funds to expand supplies. Bangkok and Jakarta both face saltwater intrusion into their overdrawn aquifers. Even through agriculture is the dominant user of water in most countries, demand concentrated in a small area exhausts local and regional sources and pollutes rivers, lakes, and coasts with untreated human and industrial waste. Most cities in Africa and Asia do not have a sewerage system. Further, most cities do not have the drains to deal with storm water and external floodwater, causing frequent, seasonal flooding. The resulting stagnant water provides breeding grounds for insect vectors of diseases (e.g., malaria). The problems in most cities are a result of poor management, not lack of water. Reducing leaks in existing piped distribution systems from the usual 60% loss of water to leaks to 12% would increase the available water 2-fold. Another way to address water shortages would be commercial, industrial, and recreational use of minimally treated waste water, such as is the case in Madras and Mexico City. Political solutions are needed to resolve inadequate water supply and waste management. PMID:12287008

CityGML - Interoperable semantic 3D city models  

NASA Astrophysics Data System (ADS)

CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research. Furthermore, its relationship to other standards from the fields of computer graphics and computer-aided architectural design and to the prospective INSPIRE model are discussed, as well as the impact CityGML has and is having on the software industry, on applications of 3D city models, and on science generally.

The dynamics of city formation*  

PubMed Central

This paper examines city formation in a country whose urban population is growing steadily over time, with new cities required to accommodate this growth. In contrast to most of the literature there is immobility of housing and urban infrastructure, and investment in these assets is taken on the basis of forward-looking behavior. In the presence of these fixed assets cities form sequentially, without the population swings in existing cities that arise in current models, but with swings in house rents. Equilibrium city size, absent government, may be larger or smaller than is efficient, depending on how urban externalities vary with population. Efficient formation of cities with internalization of externalities involves local government intervention and borrowing to finance development. The paper explores the institutions required for successful local government intervention.

The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This simulated natural color image presents a late spring view of north central Utah that includes all of the Olympic sites. The image extends from Ogden in the north, to Provo in the south; and includes the snow-capped Wasatch Mountains and the eastern part of the Great Salt Lake.

This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.

ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.

The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

Workplace danger and violence are complex problems that affect nurses more often than is recognized. The home healthcare work environment is challenging enough without the additional risks associated with working out in the open or within a client's home. Every clinician working in home health today understands the demands of visits or extended care in the home and often reluctantly accepts the involved risk. The clinician working in the rural setting may experience similar challenges, but in large metropolitan cities, it has become increasingly frightening as crime, drug use, gangs, violence, homelessness, and transportation issues have made the clinician's job much tougher. It is important to renew awareness and remind clinicians to maintain constant vigilance for personal safety. PMID:18849719

Kansas City Hopewell  

NSDL National Science Digital Library

In 2003, the University of Kansas Museum of Anthropology was awarded a Digital Library Initiatives grant for a project that would result in this rather useful and interesting digitization project. The hope was that the museum would be able to digitize some of the excellent collection of material recovered from the 30 Kansas City Hopewell archaeological sites that are located around the junction of the Kansas and Missouri Rivers. Most of the sites date to the Middle Woodland or Early Ceramic period, which ranges from 100 B.C. to 700 A.D. One of the fine features of this site is the 3D images area, which includes 32 excavated items that visitors may view in their entirety. The site is rounded out by a selection of helpful suggested readings and a collection of external links to sites such as those of the Society for American Archaeology and ArchNet.

In 1994, Dr. Paul Gorenstein of the Harvard-Smithsonian Center for Astrophysics and The Charles Hayden Planetarium, Boston received a NASA AGSE grant to develop a special workshop for Boston-area inner city teachers with little, or no background in astronomy. The objective of these 3-hour workshops was to provide some practical classroom tools by which teachers may enhance the awareness and understanding of astronomy and space science among their students. Teachers received instruction on eight basic astronomy concepts and demonstrations of inexpensive hands-on astronomy activities for the classroom. Following the success of the 1994 City Stars teacher's workshops, Dr. Gorenstein and The Charles Hayden Planetarium, Boston received a NASA IDEA grant to conduct two additional City Stars workshops, held in October 1996. This paper will display the instructional materials we developed and highlight our experiences in presenting the City Stars workshops.

Shenzhen: city of suspended possibility.  

PubMed

This essay on Shenzhen, China, presents three vignettes addressing the question of home in a city of migrants. The first section explores the ubiquitous narratives of success forming the city's foundational myth. The second follows this myth into the world of a Shenzhen filmmaker and his characters, as they navigate the tension between the idea of home and the urge to start anew, resulting in the suspended possibility of the title. The last section looks at young architects who hope to preserve the city's heterotopic sites of migrants and original villagers through architectural innovations. The cases show how an economy of desire supplements the political economy of this export-driven city. The city appears as an urban desiring machine that produces itself as an object of desire for the migrants of all classes who flock to its factories, "urban villages", white-collar jobs, luxury villas and underground economy. The essay is an encounter with the mythology of success and failure, the intertwining of home as an end and home as the beginning, and with the manipulation of space that allows residents to control their own subjectivity.

Project WISH: The Emerald City  

NASA Technical Reports Server (NTRS)

Phase 3 of Project WISH saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the E-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystem constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS. Spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System) for mass minimization. A structural dynamic analysis of the optimal structure also conducted using ASTROS enabled a study of the modes, frequencies, displacements, and accelerations of the E-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

Heritage contribution in sustainable city  

NASA Astrophysics Data System (ADS)

The concept of sustainability has been an integral part of development work since the late 1970s. Sustainability is no longer a buzzword but a reality that must be addressed by cities all over the world. Increasing empirical evidence indicates that city sustainability is not just related to technical issues, such as carbon emissions, energy consumption and waste management, or on the economic aspects of urban regeneration and growth, but also it covers social well-being of different groups living within increasingly cosmopolitan towns and cities. Heritage is seen as a major component of quality of life, features that give a city its unique character and provide the sense of belonging that lies at the core of cultural identity. In other words, heritage by providing important social and psychological benefits enrich human life with meanings and emotions, and raise quality of life as a key component of sustainability. The purpose of this paper, therefore, is to examine the role that built cultural heritage can play within sustainable urban development.

Greenhouse gas emissions from global cities.  

PubMed

The world's population is now over 50% urban, and cities make an important contribution to national greenhouse gas (GHG) emissions. Many cities are developing strategies to reduce their emissions. Here we ask how and why emissions differ between cities. Our study often global cities shows how a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the GHGs attributable to cities. Within the overall trends, however, there are differences between cities with more or less public transit while personal income also impacts heating and industrial fuel use. By including upstream emissions from fuels, GHG emissions attributable to cities exceed those from direct end use by upto 25%. Our findings should help foster intercity learning on reducing GHG emissions. PMID:19848137

Anaglyph, Salt Lake City, Utah  

NASA Technical Reports Server (NTRS)

The 2002 Winter Olympics are hosted by Salt Lake City at several venues within the city, in nearby cities, and within the adjacent Wasatch Mountains. This anaglyph image provides a stereoscopic map view of north central Utah that includes all of these Olympic sites. In the south, next to Utah Lake, Provo hosts the ice hockey competition. In the north, northeast of the Great Salt Lake, Ogden hosts curling and the nearby Snowbasin ski area hosts the downhill events. In between, southeast of the Great Salt Lake, Salt Lake City hosts the Olympic Village and the various skating events. Further east, across the Wasatch Mountains, the Park City ski resort hosts the bobsled, ski jumping, and snowboarding events. The Winter Olympics are always hosted in mountainous terrain. This view shows the dramatic landscape that makes the Salt Lake City region a world-class center for winter sports.

The stereoscopic effect of this anaglyph was created by first draping a Landsat satellite image over a Shuttle Radar Topography Mission digital elevation model and then generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive, managed by the U.S. Geological Survey (USGS).

Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter(approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Earth Science Enterprise, Washington, D.C.

Project WISH: The Emerald City  

NASA Technical Reports Server (NTRS)

Project WISH (Wandering Interplanetary Space Harbor) is a three-year design effort currently being conducted at The Ohio State University. Its goal is the design of a space oasis to be used in the exploration of the solar system during the midtwenty-first century. This spacecraft, named Emerald City, is to conduct and provide support for missions to other planetary bodies with the purpose of exploration, scientific study, and colonization. It is to sustain a crew of between 500 and 1000 people at a time, and be capable of traveling from a nominal orbit to the planets in reasonably short flight times. Such a ship obviously presents many technical and design challenges, some of which were examined through the course of Project WISH. This year, Phase 2 (1990-1991) of Project WISH was carried out. The basic design of the Emerald City resulting from Phase 1 (1989-1990) was taken and improved upon through more detailed analysis and revision. At the core of this year's study were orbital mechanics, propulsion, attitude control, and human factors. Throughout the year, these areas were examined and information was compiled on their technologies, performances, and relationships. Then, using the data obtained through these studies, two specific missions were designed: an envelope mission from a nominal orbit of 4 AU to Saturn and a single point design for a specific mission from the Earth to Mars. The latter was designed in view of the special interest that Mars is attracting for near-future space exploration. The mission to Saturn has all the first six planets within its flight envelope in less than or equal to a 3-year flight time at any time upon demand, and it has Uranus in its flight envelope most of the time upon demand. These mission studies provided data on the approximate size, weight, number of engines, and other important design values that would be required for the Emerald City.

Why Is the City Hot?  

NSDL National Science Digital Library

This investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and geographic expansion of the area over a 24-year period. Students then use surface images from Landsat, thermal data from aircraft instruments, and land use maps to compare and contrast the distribution of vegetation, variations in daily temperatures, and diversity of land usage types around the city. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 3 of four found in the Grades 5-8 Module 3 of Mission Geography.

Low-carbon infrastructure strategies for cities  

NASA Astrophysics Data System (ADS)

Reducing greenhouse gas emissions to avert potentially disastrous global climate change requires substantial redevelopment of infrastructure systems. Cities are recognized as key actors for leading such climate change mitigation efforts. We have studied the greenhouse gas inventories and underlying characteristics of 22 global cities. These cities differ in terms of their climates, income, levels of industrial activity, urban form and existing carbon intensity of electricity supply. Here we show how these differences in city characteristics lead to wide variations in the type of strategies that can be used for reducing emissions. Cities experiencing greater than ~1,500 heating degree days (below an 18 °C base), for example, will review building construction and retrofitting for cold climates. Electrification of infrastructure technologies is effective for cities where the carbon intensity of the grid is lower than ~600 tCO2e GWh-1 whereas transportation strategies will differ between low urban density (<~6,000 persons km-2) and high urban density (>~6,000 persons km-2) cities. As nation states negotiate targets and develop policies for reducing greenhouse gas emissions, attention to the specific characteristics of their cities will broaden and improve their suite of options. Beyond carbon pricing, markets and taxation, governments may develop policies and target spending towards low-carbon urban infrastructure.

The exploding cities of the developing world.  

PubMed

Some problems posed by the rapid urbanization of the developing world are reviewed. The author suggests that the fate of these rapidly growing cities will determine the fate of both nations and regions. He notes that rather than continuing to swell the megacities, such as Mexico City, recent demographic trends have been favoring secondary cities, which are facing increasing problems with proportionally fewer resources at their disposal. The problems of disease in crowded urban environments are discussed. The author presents examples of cities with declining services and quality of life, such as Kinshasa, as well as examples of more successful city development, such as Curitiba. Prospects for the successful resolution of urban problems are assessed. PMID:12348129

City, region, and in between: New York City's water supply and the insights of regional history.  

PubMed

Urban historians have greatly expanded their geographical purview in recent years, incorporating suburbs and hinterlands into their analysis of social and environmental change. Urban environmental historians and suburban historians have played a critical role in the regionalization of urban history over the last decade. This case study of the development of New York City’s water supply reveals the benefits of taking a regional approach to urban history. From the New York Public Library to Central Park’s Great Lawn to neighborhood parks, the New York City landscape bears the traces of the continuous development of the city’s water network. Expansion of the water system in rural hinterlands enabled municipal officials to put urban reservoirs to new uses, creating some of the city’s most beloved public spaces. The rehabilitation of urban infrastructure underscores the intimate linkages between rural development and the urban built environment. PMID:22826891

Deterministic Seismic Scenarios for Imphal City  

NASA Astrophysics Data System (ADS)

In this article, the spatial variation of ground motion in Imphal City has been estimated by the finite-fault seismological model coupled with site response analysis. The important seismic sources around Imphal City have been identified from the fault map and past seismicity data. The rock level acceleration time histories at Imphal City for the 1869 Cachar (Mw 7.5) earthquake and a hypothetical Mw 8.1 event in the Indo-Burma subduction zone have been estimated by a stochastic finite-fault model. Soil investigation data of 122 boreholes have been collected from several construction projects in Imphal City. Site response analysis has been carried out and the surface level ground motion has been determined for Imphal City for these two earthquake events. The results are presented in the form of peak ground acceleration (PGA) contour map. From the present study it has been ascertained that the maximum amplification for PGA over Imphal City is as high as 2.5. The obtained contour maps can serve as guidelines for identifying vulnerable areas and disaster mitigation in Imphal City.

Age-friendly cities of Europe.  

PubMed

This article summarizes how members of the European Healthy Cities Network have applied the 'healthy ageing' approach developed by the World Health Organization in their influential report on Active Ageing. Network Cities can be regarded as social laboratories testing how municipal strategies and interventions can help maintain the health and independence which characterise older people of the third age. Evidence of the orientation and scope of city interventions is derived from a series of Healthy Ageing Sub-Network symposia but principally from responses by 59 member cities to a General Evaluation Questionnaire covering Phase IV (2003-2008) of the Network. Cities elaborated four aspects of healthy ageing (a) raising awareness of older people as a resource to society (b) personal and community empowerment (c) access to the full range of services, and (d) supportive physical and social environments. In conclusion, the key message is that by applying healthy ageing strategies to programmes and plans in many sectors, city governments can potentially compress the fourth age of 'decrepitude and dependence' and expand the third age of 'achievement and independence' with more older people contributing to the social and economic life of a city.

Delaware City refinery repowering project  

SciTech Connect

With the increased use of heavy crude as a refinery feedstock and the associated increase in petroleum coke production, gasification technology has become the preferred approach to reduce coke volumes while at the same time coproducing power and steam for use in the refinery. The Motiva Enterprise Refinery at Delaware City produces approximately 2,000 tons per day of petroleum coke as a byproduct. This integrated gasification combined cycle repowering project will generate electricity and steam using the petroleum coke. The coke will be gasified using twin train Texaco Process gasifiers to fuel two 90 MW combustion turbines and heat recovery steam generators which in turn supply supplemental steam to 55 MW of existing steam turbines. The refinery's excess power will be sold into the power grid. The scope of the project also includes acid gas removal, coke slurry feed, air separation unit, solids handling, and common facilities and utilities. This paper will present an update on the project status with emphasis on project design scope.

Services Oriented Smart City Platform Based On 3d City Model Visualization  

NASA Astrophysics Data System (ADS)

The rapid technological evolution, which is characterizing all the disciplines involved within the wide concept of smart cities, is becoming a key factor to trigger true user-driven innovation. However to fully develop the Smart City concept to a wide geographical target, it is required an infrastructure that allows the integration of heterogeneous geographical information and sensor networks into a common technological ground. In this context 3D city models will play an increasingly important role in our daily lives and become an essential part of the modern city information infrastructure (Spatial Data Infrastructure). The work presented in this paper describes an innovative Services Oriented Architecture software platform aimed at providing smartcities services on top of 3D urban models. 3D city models are the basis of many applications and can became the platform for integrating city information within the Smart-Cites context. In particular the paper will investigate how the efficient visualisation of 3D city models using different levels of detail (LODs) is one of the pivotal technological challenge to support Smart-Cities applications. The goal is to provide to the final user realistic and abstract 3D representations of the urban environment and the possibility to interact with a massive amounts of semantic information contained into the geospatial 3D city model. The proposed solution, using OCG standards and a custom service to provide 3D city models, lets the users to consume the services and interact with the 3D model via Web in a more effective way.

Empirical evidence suggests that most urban systems experience a transition from a monocentric to a polycentric organization as they grow and expand. We propose here a stochastic, out-of-equilibrium model of the city, which explains the appearance of subcenters as an effect of traffic congestion. We show that congestion triggers the instability of the monocentric regime and that the number of subcenters and the total commuting distance within a city scale sublinearly with its population, predictions that are in agreement with data gathered for around 9000 U.S. cities between 1994 and 2010.

SciTech Connect

Brochure describes the Clean Cities program and includes the contact information for its 85 coalitions. Sponsored by the U.S. Department of Energy's (DOE) Vehicle Technologies Program (VTP), Clean Cities is a government-industry partnership that reduces petroleum consumption in the transportation sector. Clean Cities contributes to the energy, environmental, and economic security of the United States by supporting local decisions to reduce our dependence on imported petroleum. Established in 1993 in response to the Energy Policy Act (EPAct) of 1992, the partnership provides tools and resources for voluntary, community-centered programs to reduce consumption of petroleum-based fuels. In nearly 100 coalitions, government agencies and private companies voluntarily come together under the umbrella of Clean Cities. The partnership helps all parties identify mutual interests and meet the objectives of reducing the use of petroleum, developing regional economic opportunities, and improving air quality. Clean Cities deploys technologies and practices developed by VTP. These include idle-reduction equipment, electric-drive vehicles, fuel economy measures, and renewable and alternative fuels, such as natural gas, liquefied petroleum gas (propane), electricity, hydrogen, biofuels, and biogas. Idle-reduction equipment is targeted primarily to buses and heavy-duty trucks, which use more than 2 billion gallons of fuel every year in the United States while idling. Clean Cities fuel economy measures include public education on vehicle choice and fuel-efficient driving practices.

Indoor Radon Measurements in Mexico City  

SciTech Connect

Mexico City is one of the most populated cities in the world with almost 22 million inhabitants, located at an altitude of 2200 m. The old city was founded on an ancient lake and the zone is known by its high seismicity; indoor radon determination is an important public health issue. In this paper the data of indoor radon levels in Mexico City, measured independently by two research groups, both using Nuclear Track Detector systems but different methodologies, are correlated. The measurements were done during similar exposure periods of time, at family houses from the political administrative regions of the city. The results indicate a correlation coefficient between the two sets of data of R = 0.886. Most of the differences between the two sets of data are inherent to houses having extreme (very high or very low indoor radon) included in the statistics of each group. The total average indoor radon found in Mexico City considering the two methods was 87 Bq m{sup -3}.

Mobility and accessibility in historic cities.  

PubMed

The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to the conservation of its built heritage and demand control of the activities that occur in their areas without harm. Then, a permanent dialogue between conservatives and planners could be accomplished by joining the various sectoral policies. The study of urban mobility in historical sites was in fact the focus of this work because of their peculiarities, such as its specific characteristics of urban structure, morphology and occupation. In fact, the development of tourism in historic centers generates specific demands, such as adaptation to new uses of the houses, intensive movement of people and vehicles, illegal parking, among others. Beyond threatening the city preservation, does not provide mobility and accessibility to tourists, because these cities were not designed for the tourism conditions and needs of contemporary life. Characteristic features of Brazilian baroque cities, such as topography , the narrow streets, narrow or nonexistent sidewalks, steep turns and ramps strong, are not suitable for heavy vehicles, traffic and pedestrian circulation. Thus, studies concerning conservation urban integrated are aimed at an approach to interaction between historic preservation of the environment with the dynamic socio-economic of the local.

Cities compete to host 2012 Olympics  

NSDL National Science Digital Library

Since the era of the modern Olympic Games began in 1896, many cities have sought to host this prestigious set of athletic events that test the physical and mental abilities of those competing in individual and team competition. While the next few sites have already been selected (Torino in 2006, Beijing in 2008, and Vancouver in 2010), there has been great speculation as of late regarding which city will host the 2012 Summer Games. This past Monday, five cities submitted their official bids to the International Olympic Committee, which will make its final decision via a secret ballot in Singapore on July 6, 2005. Each of the cities was required to turn in a set of documents that covers information that will help the IOC make its final decision. Out of the five cities that have entered bids (New York, Paris, Madrid, London, and Moscow), Paris is considered by many to be the front-runner thus far. As Paris 2012 spokesman Jerome Lenfant remarked recently, "We are not overconfident but we feel, due to all the work and checking that has been done and the support from the French government, politicians, IOC members, athletes and community leaders, we think we have put together the best of France."The first link provides a nice introduction to the recent Olympic host city competition process provided by the San Francisco Chronicle. The second link will take visitors to a news piece from the Telegraph in Britain that details the start of this highly publicized competition, along with providing some odds on which city may win, proffered by a prominent British bookmaker. The third link details the public relations campaign and broad vision put forth by the people behind the city of London's bid for the 2012 Olympic Games. The fourth link whisks visitors across the Channel, where they will learn about the ambitious plans offered by the leaders who are putting forth the City of Lights for the same event. Moving up to the Moscow River, visitors will be given an intimate introduction to Moscow's proposed plans for the same august set of events by clicking on the fifth link. It should be noted that the site offers this forceful (and potentially convincing) epigram: "Russia is eternal, yet Russia is new." The sixth link leads to the Iberian-themed plans offered by Madrid, which includes a number of video clips of the site that will be transformed into Olympic-worthy locales, provided it is selected as the host location, of course. Not to be forgotten, the final link will take visitors to the official bid website for New York City.

Development, primacy, and systems of cities.  

PubMed

The relationship between the evolutionary changes in the city size distribution of nationally defined urban systems and the process of socioeconomic development is examined. Attention is directed to the problems of defining and measuring changes in city size distributions, using the results to test empirically the relationship of such changes to the development process. Existing theoretical structures and empirical generalizations which have tried to explain or to describe, respectively, the hierarchical relationships of cities are represented by central place theory and rank size relationships. The problem is not that deviations exist but that an adequate definition is lacking of urban systems on the 1 hand, and a universal measure of city size distribution, which could be applied to any system irrespective of its level of development, on the other. The problem of measuring changes in city size distributions is further compounded by the lack of sufficient reliable information about different systems of cities for the purposes of empirical comparative analysis. Changes in city size distributions have thus far been viewed largely within the framework of classic equilibrium theory. A more differentiated continuum of the development process should replace the bioplar continuum of underdeveloped developed countries in relating changes in city size distribution with development. Implicit in this distinction is the view that processes which influence spatial organization during the early formative stages of development are inherently different from those operating during the more advanced stages. 2 approaches were used to examine the relationship between national levels of development and primacy: a comparative analysis of a large number of countries at a given point in time; and a historical analysis of a limited sample of 2 advanced countries, the US and Great Britain. The 75 countries included in this study cover a wide range of characteristics. The study found a significant association between the degree of primacy of distributions of cities and their socioeconomic level of development; and the form of the primacy curve (or its evolution with development) seemed to follow a consistent pattern in which the peak of primacy obtained during the stages of socioeconomic transition with countries being less primate in either direction from that peak. This pattern is the result of 2 reverse influences of the development process on the spatial structure of countries--centralization and concentration beginning with the rise of cities and a decentralization and spread effect accompanying the increasing influence and importance of the periphery and structural changes in the pattern of authority.

On the Internet of Things, smart cities and the WHO Healthy Cities  

PubMed Central

This article gives a brief overview of the Internet of Things (IoT) for cities, offering examples of IoT-powered 21st century smart cities, including the experience of the Spanish city of Barcelona in implementing its own IoT-driven services to improve the quality of life of its people through measures that promote an eco-friendly, sustainable environment. The potential benefits as well as the challenges associated with IoT for cities are discussed. Much of the 'big data' that are continuously generated by IoT sensors, devices, systems and services are geo-tagged or geo-located. The importance of having robust, intelligent geospatial analytics systems in place to process and make sense of such data in real time cannot therefore be overestimated. The authors argue that IoT-powered smart cities stand better chances of becoming healthier cities. The World Health Organization (WHO) Healthy Cities Network and associated national networks have hundreds of member cities around the world that could benefit from, and harness the power of, IoT to improve the health and well-being of their local populations.

Air pollution assessment on city of Tirana  

NASA Astrophysics Data System (ADS)

Air pollution is one of the hot topics on nowadays studies. This problem is often encountered on urban centers, especially on metropolitan areas. These areas are usually characterized by densely population, heavy traffic rates and the presence of many industrial plants on their suburbs. Problems regarding to air pollution on these areas are more evident over metropolitan areas in developing countries. Air pollution is mostly related to health effects, especially in outdoor environments. These effects regards primarily on respiratory and cardiovascular diseases. Air pollution assessment on a specific area requires not only the estimation of pollutant concentrations in that area, but also determination of their principal sources as well as prediction of eventual scenarios on the area under investigation. This study is focused on air pollution assessment on the city of Tirana, which is the major urban centre and the capital city of Albania. This city has about one million inhabitants. During the last 20 years, its population has grown about four fold, and it is still growing. Because of Albania is a developing country, its capital city is involved on serious environmental problems. Considering these facts, we have conducted continuous monitoring campaigns on several sites of Tirana. These monitoring campaigns consist on measurement of several pollutant gases (SO2, CO, CO2, NOx, etc.) and particulate matter over a period of 20 months. In this paper there are obtained diurnal and annual variations of pollutant concentrations, there is modeled their spatial distributions over the area of the city, and there are estimated the potential contributions of principal sources like traffic and industrial plants. During the entire monitoring campaign there are recorded also meteorological parameters, like temperature, relative humidity, atmospheric pressure, wind speed, wind direction, precipitations, etc. In this way we have tried to obtain the correlations between pollutant concentrations and meteorological parameters, and so to estimate their contribution on air pollution situation in this city. Overall measurement results indicate a critical situation of air pollution in this city, where pollutant concentrations exceed international recommendations. Because of in Albania these types of studies are very rare; the air pollution assessment in the capital city Tirana has an enormous importance not only for this city but also in general for entire the country.

Spatio-temporal synchrony of influenza in cities across Israel: the "Israel is one city" hypothesis.  

PubMed

We analysed an 11-year dataset (1998-2009) of Influenza-Like Illness (ILI) that was based on surveillance of ?23% of Israel's population. We examined whether the level of synchrony of ILI epidemics in Israel's 12 largest cities is high enough to view Israel as a single epidemiological unit. Two methods were developed to assess the synchrony: (1) City-specific attack rates were fitted to a simple model in order to estimate the temporal differences in attack rates and spatial differences in reporting rates of ILI. The model showed good fit to the data (R2 ?=? 0.76) and revealed considerable differences in reporting rates of ILI in different cities (up to a factor of 2.2). (2) A statistical test was developed to examine the null hypothesis (H0) that ILI incidence curves in two cities are essentially identical, and was tested using ILI data. Upon examining all possible pairs of incidence curves, 77.4% of pairs were found not to be different (H0 was not rejected). It was concluded that all cities generally have the same attack rate and follow the same epidemic curve each season, although the attack rate changes from season to season, providing strong support for the "Israel is one city" hypothesis. The cities which were the most out of synchronization were Bnei Brak, Beersheba and Haifa, the latter two being geographically remote from all other cities in the dataset and the former geographically very close to several other cities but socially separate due to being populated almost exclusively by ultra-orthodox Jews. Further evidence of assortative mixing of the ultra-orthodox population can be found in the 2001-2002 season, when ultra-orthodox cities and neighborhoods showed distinctly different incidence curves compared to the general population.

LGBTQs in the city, queering urban space.  

PubMed

Since the 1960s, lesbian, gay, bisexual, transgender and queer (LGBTQ) culture has developed in big cities and metropolises everywhere (not only in the West, but also in Asia, Latin America and indeed Africa). This essay examines how cities provide the spatial conditions necessary for the formation of such emancipatory movements based on identity politics and strategies which transcend binary gender dualism. The starting point of this investigation is my thesis that only urban life enables LGBTQ individuals to live their lives fully, realize their (sexual) identities, and furthermore organize themselves collectively, become publicly visible, and appropriate urban, societal and political spaces.

The vision of a smart city  

SciTech Connect

The vision of ''Smart Cities'' is the urban center of the future, made safe, secure environmentally green, and efficient because all structures--whether for power, water, transportation, etc. are designed, constructed, and maintained making use of advanced, integrated materials, sensors, electronics, and networks which are interfaced with computerized systems comprised of databases, tracking, and decision-making algorithms. This paper discusses a current initiative being led by the Brookhaven National Laboratory to create a research, development and deployment agenda that advances this vision. This is anchored in the application of new technology to current urban center issues while looking 20 years into the future and conceptualizing a city framework that may exist.

Means of livelihood of city populations: a livelihood classification of the cities in India.  

PubMed

Indian censuses provide useful data on livelihood. These data give a picture of the distribution of population deriving their living from different economic activities. According to the 1951 census, 73 cities in the country had a population over 1 lakh. These cities were, more or less, evenly distributed in the different States of the Union. Of the populations in these cities combined, nearly 40% derived its livelihood from the services and miscellaneous sources, approximately 1/4 from production other than cultivation, 1/4 from commerce, and the remaining few from transport and agriculture. These averages were fairly similar for large and small cities. Of the 32 largest cities which showed predominance of their population in 1 or more livelihood, there were about 10 in industrial-manufacturing, 6 in commerce, 9 in transport, and 10 in services. 2 of the 3 port cities, Bombay and Madras, were broad-based in employment while Calcutta was predominant in commerce. There was little uniformity in the livelihood patterns of capital cities. PMID:12309859

Informal science education at Science City  

NASA Astrophysics Data System (ADS)

The presentation of chemistry within informal learning environments, specifically science museums and science centers is very sparse. This work examines learning in Kansas City's Science City's Astronaut Training Center in order to identify specific behaviors associated with visitors' perception of learning and their attitudes toward space and science to develop an effective chemistry exhibit. Grounded in social-constructivism and the Contextual Model of Learning, this work approaches learning in informal environments as resulting from social interactions constructed over time from interaction between visitors. Visitors to the Astronaut Training Center were surveyed both during their visit and a year after the visit to establish their perceptions of behavior within the exhibit and attitudes toward space and science. Observations of visitor behavior and a survey of the Science City staff were used to corroborate visitor responses. Eighty-six percent of visitors to Science City indicated they had learned from their experiences in the Astronaut Training Center. No correlation was found between this perception of learning and visitor's interactions with exhibit stations. Visitor attitudes were generally positive toward learning in informal settings and space science as it was presented in the exhibit. Visitors also felt positively toward using video game technology as learning tools. This opens opportunities to developing chemistry exhibits using video technology to lessen the waste stream produced by a full scale chemistry exhibit.

Project Wish: The Emerald City, phase 3  

NASA Technical Reports Server (NTRS)

Phase 3 of Project Wish saw the evolution of the Emerald City (E-City) from a collection of specialized independent analyses and ideas to a working structural design integrated with major support systems and analyses. Emphasis was placed on comparing and contrasting the closed and open cycle gas core nuclear rocket engines to further determine the optimum propulsive system for the C-City. Power and thermal control requirements were then defined and the question of how to meet these requirements was addressed. Software was developed to automate the mission/system/configuration analysis so changes dictated by various subsystems constraints could be managed efficiently and analyzed interactively. In addition, the liquid hydrogen propellant tank was statically designed for minimum mass and shape optimization using a finite element modeling package called SDRC I-DEAS while spoke and shaft cross-sectional areas were optimized on ASTROS (Automated Structural Optimization System). A structural dynamic analysis also conducted using ASTROS enabled a study of the displacements, accelerations, modes and frequencies of the C-City. Finally, the attitude control system design began with an initial mass moment of inertia analysis and was then designed and optimized using linear quadratic regulator control theory.

Pollutant dispersion characteristics in Dhaka city, Bangladesh  

NASA Astrophysics Data System (ADS)

Air pollution is a major environmental concern in major cities around the world. The major causes of air pollution include rapid industrialization/urbanization and increased non environment-friendly energy production. This paper analyses the atmospheric pollutant such as carbon monoxide (CO) and particulate matter (PM) dispersion characteristics of Dhaka city. The yearly and diurnal variations of pollutant concentration are described by taking into consideration of both meteorological and emission source parameters highlighting washout effect due to rainfall and inversion phenomena. Concentration of PM (both PM2.5 and PM10) and CO in the ambient air are measured for a period of one year with Airmetric Minivol air samplers and Gas Chromatographic (GC) technique, respectively. The trend over the year shows an increase in the monthly average hourly PM and CO concentrations in winter months (November to March) when both PM10 and PM2.5 annual average concentrations (about 130 and 95 ?g m-3, respectively) exhibit levels exceeding World Health Organization (WHO) guidelines as well as exceed more than twice the national standards of annual PM10 (50 ?g m-3) and PM2.5 (15 ?g m-3) concentrations. Such high pollutant concentrations may have significant health implications for residents of Dhaka city. It is also found that the PM concentration increases with the increase of wind speed during dry winter season and is also influenced by transboundary air pollution. The data and subsequent recommendations can be useful in formulating air quality management strategies for the Dhaka city.

Measure the Climate, Model the City  

NASA Astrophysics Data System (ADS)

Modern large cities are characterized by a high building concentration, little aeration and lack of green spaces. Such characteristics create an urban climate which is different from the climate outside of cities. An example of an urban climate effect is the so-called Urban Heat Island: cities tend to be warmer than the surrounding rural areas. The higher temperature results in an increase in energy consumption since people, especially in summer, use artificial means to cool themselves. Although means of mitigating the UHI effect exist, they are difficult to justify, as knowledge about urban climate is limited, and analysis tools are lacking. This paper presents the work carried during the 2010 MSc Geomatics Synthesis Project. A 3D spatial relational database has been implemented which is meant to act as starting point in the development of a 3D climate-enabled geographical information system. To this end, the database stores 3D geometries representing the built environment and its thematic properties. The database is also able to store measurements of climate parameters, in this case temperature, obtained through mobile sensors. Spatial analyses and queries are supported, allowing users to calculate areas, distances, buffers, add and remove geometries and thematic attributes. The database design is based on the CityGML information model which has been extended to allow the storage of climate parameters relevant to urban climate research.

Seismic Hazard Management in Mexico City  

NASA Astrophysics Data System (ADS)

Mexico City is one of the largest cities in the world. More than 8.5 million residents and 4.5 million floating population are in the city itself, but with the surrounding suburbs the number of people that could be affected by natural and man-made hazards rises to approximately 20 million. The main risk to the city as a whole is a large magnitude earthquake. Since there is reason to prepare for a credible seismic scenario of Mw = 8.2, which would exceed the damages caused during the 1985 earthquake (Mw = 8.1), we founded the Metropolitan Geologic Service (MGS) in 1998. The MGS has developed geologic and seismic hazard maps for the city (http:www.proteccioncivil.df.gob.mx). The maps include three separate risk maps for low height (3 stories), medium height (10 stories) and tall buildings (10 stories). The maps were prepared by using the maximum horizontal accelerations documented during the 1985 earthquake, and wave propagation modeling for buildings of different resonant periods (T = 0.0, 1.0 and 2.0 sec). In all cases, the risk zones were adjusted to include documented damage during the 1957, 1979 and 1985 earthquakes. All three maps show a high risk zone in the north-central portion of the city, elongated in a N-S direction, which corresponds with a narrow graben where the thickness of alluvial sediments is particularly large, and where wave amplification is accentuated. Preparation of these maps, and others used for planning, has been facilitated by the ongoing elaboration of a Dynamic Geographical Information System, which is based on geo-scientific information, includes all types of risks, and incorporates vulnerability models. From the risk management standpoint, we have elaborated the Permanent Contingency Plan for Mexico City, which in its Earthquakes chapter includes plans for coordination and for organizing attention to the population in the event of a seismic disaster. This Permanent Plan follows the philosophy of Descartes' Method, has 11 processes (6 main and 5 support processes), and is coordinated by Center of Control of Operations under the overall direction of the Head of Government of the Federal District. We are also working on the definition of the Basic Elements for a New Paradigm in the Prevention of Disasters, to investigate the origins, causes and effects of disaster phenomena, and to plan and implement a suitable response from the Government to better protect the population.

Manila, mega city by the year 2000.  

PubMed

Fueled by internal migration, Manila's rapid population has left the philippine capital unable to provide basic services to the city's population. With an annual growth rate of 2.3%, Manila's current population of 8 million is expected to increase to 10 million by the year 2000. The number of migrants to the city has steadily increased over the last 20 years; a recent study indicates that 1/2 of the population currently living in the Manila metropolitan area was born in the province. The growth that began in the 1970 has coincided with increases in the birth rate. As one expert noted, by the year 2000, 1/2 of the city's growth will be due to a high birth rate. The rapidly growing population has made it difficult for the government to provide adequate food, water systems, and other services. The increasing number of people living in squalor are at great risk on contracting communicable diseases, and suffer from poor maternal and child health, inadequate nutrition, and lack safe drinking water and waste disposal systems. Most of the migrants come to the city looking for employment and opportunity, but many are left economically trapped, working in low-paying and often gruelling jobs. Critics attribute the population imbalance to government policies that have favored the city and neglected the countryside. Realizing the dangers associated with the massive urban growth, the government has begun to address the problem. It has asked business to invest in the countryside, it has built roads and bridges there to spur economic growth, and has tried to convince people to return to the province. PMID:12343165

[Climatope change and its relations with city development of Haikou City in 1961-2007].  

PubMed

Based on the 1961-2007 meteorological data of Haikou City and its urbanization level in 1989-2007, this paper studied the climatope change and its relations with city development of the City. In 1995-2007, the mean annual air temperature in Haikou had an obvious increase, with an increment of 0.93 degrees C x a(-1), while the mean annual relative humidity decreased obviously, with a decrement of 3% per year, compared with those in 1961-1990. Both the mean annual air temperature and the mean annual relative humidity had significant correlations with the urbanization level of Haikou, suggesting that urbanization could better explain the recent 20 years variation of climate elements in Haikou. The city development of Haikou not only changed the climatope elements, but also affected the air quality, making the frequency of acid rain increased, and the mean annual acid rain pH value decreased.

IBMDCH: illegal building monitoring in digital city based on HPC  

NASA Astrophysics Data System (ADS)

Every year city planners spend a large amount of money and time to monitor illegal buildings by officials on site. Due to such slowness, some city planners ask experts to look for illegal buildings by interpreting remote sensing image. Considering the high cost of human resource, some city planners start to use computer as an aid to the experts. In the way, still, the cost and the time can not satisfy the need for large-scale city monitoring. In order to realize automatic and fast building monitoring, we propose IBMDCH (Illegal Building Monitoring in Digital City based on HPC), in which all illegal buildings in a city can be found out much faster by comparing buildings-image or buildings change image with the official city planning graph of a digital city based on HPC (High Performance Computing).

Evaluation of partnership working in cities in phase IV of the WHO Healthy Cities Network.  

PubMed

An intersectoral partnership for health improvement is a requirement of the WHO European Healthy Cities Network of municipalities. A review was undertaken in 59 cities based on responses to a structured questionnaire covering phase IV of the network (2003-2008). Cities usually combined formal and informal working partnerships in a pattern seen in previous phases. However, these encompassed more sectors than previously and achieved greater degrees of collaborative planning and implementation. Additional WHO technical support and networking in phase IV significantly enhanced collaboration with the urban planning sector. Critical success factors were high-level political commitment and a well-organized Healthy City office. Partnerships remain a successful component of Healthy City working. The core principles, purpose and intellectual rationale for intersectoral partnerships remain valid and fit for purpose. This applied to long-established phase III cities as well as newcomers to phase IV. The network, and in particular the WHO brand, is well regarded and encourages political and organizational engagement and is a source of support and technical expertise. A key challenge is to apply a more rigorous analytical framework and theory-informed approach to reviewing partnership and collaboration parameters. PMID:22592961

Space Radar Image of Star City, Russia  

NASA Technical Reports Server (NTRS)

This radar image shows the Star City cosmonaut training center, east of Moscow, Russia. Four American astronauts are training here for future long-duration flights aboard the Russian Mir space station. These joint flights are giving NASA and the Russian Space Agency experience necessary for the construction of the international Alpha space station, beginning in late 1997. This image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR), on its 62nd orbit on October 3, 1994. This Star City image is centered at 55.55 degrees north latitude and 38.0 degrees east longitude. The area shown is approximately 32 kilometers by 49 kilometers (20 miles by 30 miles). North is to the top in this image. The radar illumination is from the top of the image. The image was produced using three channels of SIR-C radar data: red indicates L-band (23 cm wavelength, horizontally transmitted and received); green indicates L-band (horizontally transmitted and vertically received); blue indicates C-band (6 cm wavelength, horizontally transmitted and vertically received). In general, dark pink areas are agricultural; pink and light blue areas are urban communities; black areas represent lakes and rivers; dark blue areas are cleared forest; and light green areas are forested. The prominent black runways just right of center are Shchelkovo Airfield, about 4 km long. The textured pale blue-green area east and southeast of Shchelkovo Airfield is forest. Just east of the runways is a thin railroad line running southeast; the Star City compound lies just east of the small bend in the rail line. Star City contains the living quarters and training facilities for Russian cosmonauts and their families. Moscow's inner loop road is visible at the lower left edge of the image. The Kremlin is just off the left edge, on the banks of the meandering Moskva River. The Klyazma River snakes to the southeast from the reservoir in the upper left (shown in bright red), passing just east of Star City and flowing off the lower right edge of the image. The dark blue band of the Vorya River runs north-south in the upper right quadrant, east of Star City. SIR-C/X-SAR radar images are being compared with data from the Russian radar satellite Almaz to evaluate the usefulness of a permanent orbital radar platform in monitoring Earth s environment and ecology.

Lead in ancient Rome's city waters.  

PubMed

It is now universally accepted that utilization of lead for domestic purposes and water distribution presents a major health hazard. The ancient Roman world was unaware of these risks. How far the gigantic network of lead pipes used in ancient Rome compromised public health in the city is unknown. Lead isotopes in sediments from the harbor of Imperial Rome register the presence of a strong anthropogenic component during the beginning of the Common Era and the Early Middle Ages. They demonstrate that the lead pipes of the water distribution system increased Pb contents in drinking water of the capital city by up to two orders of magnitude over the natural background. The Pb isotope record shows that the discontinuities in the pollution of the Tiber by lead are intimately entwined with the major issues affecting Late Antique Rome and its water distribution system.

Scaling of Prosocial Behavior in Cities  

PubMed Central

Previous research has examined how various behaviors scale in cities in relation to their population size. Behavior related to innovation and productivity has been found to increase per capita as the size of the city increases, a phenomenon known as superlinear scaling. Criminal behavior has also been found to scaling superlinearly. Here we examine a variety of prosocial behaviors (e.g., voting and organ donation), which also would be presumed to be categorized into a single class of scaling with population. We find that, unlike productivity and innovation, prosocial behaviors do not scale in a unified manner. We argue how this might be due to the nature of interactions that are distinct for different prosocial behaviors.

Maximum Noise Levels in City Traffic  

NASA Astrophysics Data System (ADS)

Manual and automatic noise measurements were made along 13 streets in Gothenburg, Sweden to explore sources of maximum noise levels. Noise from different types of vehicles driven in a realistic way in inner city traffic was measured. In summary, the results show that the most important vehicle component as regards the maximum noise level in inner city traffic was a medium-weight truck (delivery truck). Among the higher noise levels measured (>80 dB(A)), this type of vehicle is dominant. This is supported by tests that demonstrated that the noise level of a light truck, driven in a realistic way, exceeds that of cars and is on the same level as heavy trucks. Measures can be taken against the noisiest vehicle types specifically, and the noise load can be limited by introducing noise bans for particular streets in which vehicles that emit greater than a certain noise level would not be allowed use of the street.

Since already half of the world population lives in cities - and this number is predicted to increase in coming years and decades - making big urban areas comfortable places gains interest of the general public and policy makers, as well as scientists. It is well known fact that urban climate differs significantly from the climate of rural areas. This is caused by several factors such as lack of evaporation, anthropogenic heat, specific geometry of street canyons, etc. Magnitude of the effect of each of these factors is a widely discussed topic throughout the literature. One of the most important factors is a lack of evaporation and consequent change in the energy balance compared to rural areas. This research aims to reveal the effect of water in the city on the temperature and comfort of inhabitants. We hypothesize that water works as a cooling liquid of cities and the lack of it is the main reason for formation of so called urban heat island. We focus on two major ways water can be stored in cities; in a form of open water areas, and in plants and green areas in general. Open water buffers the temperature extremes in its surroundings, but also has a warming effect at night due to its higher heat capacity compared to buildings and pavements. Trees are then providing shading and transpirate significant amount of water. On the other hand, shading effect alone, as provided by for example mash, can increase the temperature in the area simply because it prevents ventilation. Human comfort is however not determined only by temperature; for example higher air humidity is known to lower comfort of inhabitants and therefore mitigate the cooling effect of evaporation. Understanding properly the different effects of urban climate, and the particular aspects that can influence it, is important for optimal urban design that provides pleasant living environment.

Urban flood analysis in Oklahoma City, Oklahoma  

USGS Publications Warehouse

Flood insurance study information from the Federal Emergency Management Agency is utilized to estimate future flood hazard in Oklahoma City, Oklahoma. Techniques are described for estimating future urban runoff estimates. A method of developing stream cross section rating curves is explained. Future runoff estimates are used in conjuction with the rating curves to develop an estimate of 50- and 100- year flood profiles that would result from future urban development.
