Purpose - This paper aims to investigate users' individual differences such as gender and status in service quality assessment of Independent University, Bangladesh Library (IUBL), a top-ranking private university library in Bangladesh. Design/methodology/approach - A survey was conducted among IUBL users using modified version of SERVQUAL instrument. User responses for minimum, expected, and perceived services were calculated by gender and status. The gap scores between perceived and minimum services (adequacy gap) and perceived and expected services (superiority gap) by different groups were computed. Finally, the gap scores of gender and status groups were compared statistically using Mann-Whitney and Kruskal-Wallis tests. Findings - The results showed overall IUBL met minimum service e...
Bangladesh has experienced the largest mass poisoning of a population in history owing to contamination of groundwater with naturally occurring inorganic arsenic. Prolonged drinking of such water risks development of diseases and therefore has implications for children's cognitive and psychological development. This study examines the effect of arsenic contamination of tubewells, the primary source of drinking water at home, on the learning outcome of school-going children in rural Bangladesh using recent nationally representative data on secondary school children. We unambiguously find a negative and statistically significant correlation between mathematics scores and arsenic-contaminated drinking tubewells at home, net of the child's socio-economic status, parental background and school specific unobserved correlates of learning. Similar correlations are found for an alternative measure of student achievement and subjective well-being (i.e. self-reported measure of life satisfaction), of the student. We conclude by discussing the policy implication of our findings in the context of the current debate over the adverse effect of arsenic poisoning on children. (Contains 9 tables and 2 figures.)
The low social status of women and the preference for sons determine a high rate of sex-selective abortion or, more specifically, female feticide, in South Asian countries. Although each of them, irrespective of its abortion policy, strictly condemns sex-selective abortion, data suggest high rates of such procedures in India, Nepal, China and Bangladesh. This paper reviews the current situation of sex-selective abortion, the laws related to it and the factors contributing to its occurrence within these countries. Based on this review, it is concluded that sex selective abortion is a public health issue as it contributes to high maternal mortality. Abortion policies of South Asian countries vary greatly and this influences the frequency of reporting of cases. Several socio-economic factors ...
Exposure to arsenic in groundwater via drinking remains unabated for millions of villagers in Bangladesh. Since a blanket testing campaign using test kits almost a decade ago, millions of new wells have been installed but not tested; thus affordable testing is needed. The performance of the Arsenic Econo-Quick (EQ) kit was evaluated by blindly testing 123 wells in Bangladesh and comparing with laboratory measurements; 65 wells were tested twice. A subset of the same 123 wells was also tested using the Hach EZ kit in the field and the Digital Arsenator in the laboratory in Bangladesh. The EQ kit correctly determined the status of 110 (89%) and 113 (92%) out of 123 wells relative to the WHO guideline (10 ?g/L) and the Bangladesh standard (50 ?g/L), respectively. Relative to the WHO guideline, all misclassifications were underestimates for wells containing between >10 and 27 ?g/L As. Relative to the Bangladesh As standard, over- and underestimates were evenly distributed. Given its short reaction time of 10 min relative to the Hach EZ and its lower cost compared to the Arsenator, the EQ kit appears to have several advantages for well testing in Bangladesh and elsewhere.

This article examines current legal and regulatory issues of Islamic banking in Bangladesh. The most important issue in this context is the lack of a well-defined regulatory and supervisory framework for Islamic banks for their effective functioning in line with the tenets of Shariah. Other major issues come from the absence of an interbank Islamic money market, following the same policy and guidelines for Islamic and conventional banking by the Bangladesh Bank, presence of a discriminatory legal reserve requirement for Islamic and conventional banking, prevalence of a restrictive environment in the capital market, and the lack of legal support and protection of Bangladesh Bank to avoid the associated risks of Islamic banks. For this purpose, it is suggested that Islamic banks in Banglades...
This paper includes a review of international sustainable forestry development followed by an analysis of forest policies in Bangladesh. There have been four different government forest policies in Bangladesh since 1894. The first two forest policies (1894 and 1955) were exploitative in nature. Most of the regulatory documents were developed during the first two policy periods. The third forest policy instituted in 1979 by the sovereign Bangladesh government had contradictory elements and mutually inconsistent policy statements. It addressed for the first time forestry extension through mass motivation campaign. Current forest policy formulated in 1994 has been considered to be the most elaborate policy in the history of the country. Under this policy, participatory social forestry has bee...
Abstract in spanish OBJETIVO: Evaluar la prevalencia, el tratamiento y el control de la hipertensión, así como el conocimiento de este problema, entre las personas de edad en Bangladesh y la India. MÉTODOS: Se seleccionó una muestra comunitaria de 1203 personas de edad avanzada (entre ellas 670 mujeres; edad media: 70 años) empleando una técnica de muestreo por conglomerados polietápico de dos sitios en Bangladesh y tres sitios en la India. RESULTADOS: La prevalencia general de hipert (more) ensión (criterios OMS/Sociedad Internacional de la Hipertensión) era del 65% (intervalo de confianza del 95% = 62%-67%). La prevalencia era mayor en los entornos urbanos que en las zonas rurales, pero no difirió significativamente entre los sexos. Los análisis de regresión logística múltiple revelaron que la prevalencia de hipertensión estaba correlacionada marcadamente con un mayor índice de masa corporal, con un mayor nivel de instrucción y con la prevalencia de diabetes mellitus. La actividad física, la residencia en zonas rurales y la condición de fumador a la sazón eran factores inversamente relacionados con la prevalencia de hipertensión. Entre las personas estudiadas que tenían hipertensión, el 45% sabían que la padecían y el 40% estaban tomando medicación antihipertensiva, pero sólo un 10% había alcanzado los niveles estipulados en los criterios del Sexto Comité Nacional Mixto de los EE.UU. sobre la Detección, la Evaluación y el Tratamiento de la Hipertensión. El hecho de haber visitado a un médico durante el año precedente, la posesión de un nivel de instrucción alto y la condición de mujer resultaron ser factores notablemente correlacionados con el conocimiento de la propia hipertensión. CONCLUSIÓN: Nuestros resultados subrayan la necesidad de aplicar regímenes terapéuticos eficaces y de bajo costo basados en los niveles absolutos de riesgo cardiovascular teniendo en cuenta el contexto económico. Desde una perspectiva de salud pública, la única manera de abordar de forma sostenible la alta prevalencia de hipertensión en el subcontinente indio es una estrategia orientada a reducir la presión arterial promedio en la población. Abstract in english OBJECTIVE: To evaluate the prevalence, awareness, treatment and control of hypertension among elderly individuals in Bangladesh and India. METHOD: A community-based sample of 1203 elderly individuals (670 women; mean age, 70 years) was selected using a multistage cluster sampling technique from two sites in Bangladesh and three sites in India. FINDINGS: The overall prevalence of hypertension (WHO-International Society for Hypertension criteria) was 65% (95% confidence int (more) erval = 62-67%). The prevalence was higher in urban than rural areas, but did not differ significantly between the sexes. Multiple logistic regression analyses identified a higher body mass index, higher education status and prevalent diabetes mellitus as important correlates of the prevalence of hypertension. Physical activity, rural residence, and current smoking were inversely related to the prevalence of hypertension. Among study subjects who had hypertension, 45% were aware of their condition, 40% were taking anti-hypertensive medications, but only 10% achieved the level established by the US Sixth Joint National Committee on Detection, Evaluation and Treatment of Hypertension (JNC VI)/WHO criteria. A visit to a physician in the previous year, higher educational attainment and being female emerged as important correlates of hypertension awareness. CONCLUSIONS: Our findings emphasize the need to implement effective and low cost management regimens based on absolute levels of cardiovascular risk appropriate for the economic context. From a public health perspective, the only sustainable approach to the high prevalence of hypertension in the Indian subcontinent is through a strategy to reduce the average blood pressure in the population.
Arsenic contamination of shallow tube well drinking water is an urgent health problem in Bangladesh. Current arsenic mitigation solutions, including (household) arsenic removal options, do not always provide a sustainable alternative for safe drinking water. A novel technology, Subsurface Arsenic Re...
Bangladesh, it is by now well-known, is at the receiving end, in the literal sense of the term, of the global climate change and its potential impacts. She contributes very little to the current global emission of greenhouse gases (GHGs). The Emission Inventory under the present umbrella project, Bangladesh Climate Change Study (BCCS), has found that her annual emission of carbon has been only 3.99 mn metric tons per year. An earlier study arrived at exactly the same figure. The figures for estimated release of methane is far less firm. The estimated methane emission in 1990 could be anywhere between 1 million and 6 million metric tons. In any case the total emission is unlikely to be more than one-half of one percent of the global total. On the other hand, however, she faces specter of widespread and more frequent floods, more frequent droughts, cyclones and above all sea-level rise (SLR) which may inundate a substantial part of the country all of these bringing in immeasurable misery and destitution and loss of income, employment and growth. One would expect that in such a situation, Bangladesh`s basic concern should be to prepare an appropriate adaptation strategy. This is already a major policy concern of the Government. There is, however, an increasing realization that Bangladesh should as well emphasize an appropriate mitigation strategy (MS). There may be at least three reasons why this should be so. The first is that she is a signatory of the Framework Convention on Climate Change. The second is that in the medium, if not short term she expects major growth due to a developing economy. Third is that Bangladesh depends primarily on fossil fuel imports for energy, and will become a larger source with further development.

Background The agro-ecology and poultry husbandry of the south Asian and south-east Asian countries share common features, however, with noticeable differences. Hence, the ecological determinants associated with risk of highly pathogenic avian influenza (HPAI-H5N1) outbreaks are expected to differ between Bangladesh and e.g., Thailand and Vietnam. The primary aim of the current study was to establish ecological determinants associated with the risk of HPAI-H5N1 outbreaks at subdistrict level in Bangladesh. The secondary aim was to explore the performance of two different statistical modeling approaches for unmeasured spatially correlated variation. Methodology/Principal Findings An ecological study at subdistrict level in Bangladesh was performed with 138 subdistricts with HPAI-H5N1 outbreaks during 2007–2008, and 326 subdistricts with no outbreaks. The association between ecological determinants and HPAI-H5N1 outbreaks was examined using a generalized linear mixed model. Spatial clustering of the ecological data was modeled using 1) an intrinsic conditional autoregressive (ICAR) model at subdistrict level considering their first order neighbors, and 2) a multilevel (ML) model with subdistricts nested within districts. Ecological determinants significantly associated with risk of HPAI-H5N1 outbreaks at subdistrict level were migratory birds' staging areas, river network, household density, literacy rate, poultry density, live bird markets, and highway network. Predictive risk maps were derived based on the resulting models. The resulting models indicate that the ML model absorbed some of the covariate effect of the ICAR model because of the neighbor structure implied in the two different models. Conclusions/Significance The study identified a new set of ecological determinants related to river networks, migratory birds' staging areas and literacy rate in addition to already known risk factors, and clarified that the generalized concept of free grazing duck and duck-rice cultivation interacted ecology are not significant determinants for Bangladesh. These findings will refine current understanding of the HPAI-H5N1 epidemiology in Bangladesh.

The status of women in the countries included in the Economic and Social Commission for Asia and the Pacific (ESCAP) varies widely from home labor and childbearing to social and political participation. In countries where the total fertility rate is high (over 6), such as Bangladesh, Pakistan, and Nepal, the status of women is low. Bangladesh, Pakistan, and Nepal, along with India, Sri Lanka, and China, also have the lowest levels of per capita income. The education of women is one of the earmarks of social development. Education enables women to delay marriage, reduce fertility, and participate in the economy. Between 1970 and 1980, the female literacy rate increased 10% in Thailand, Singapore, Malaysia, Sri Lanka, and the Philippines; and 5% in Bangladesh, Pakistan, and Nepal. Women's participation in the labor force is determined both by the stage of development of the country and by cultural factors. In Muslim countries the level of women's participation in the labor force is low. In Thailand and China it is very high. Women with the most education are likeliest to work in professional and administrative jobs. Self-employed women tend to have as little status and as many children as unpaid family workers, and women working in agriculture are almost as badly off. In Asia and the Pacific, except for Muslim countries, women have participated actively in family planning programs. In several countries in the region, women have been active in politics, but mostly at the local level. If women are to be integrated into the development process in the countries of Asia and the Pacific, attention must be given to their education and employment, to increasing the role of men in household and child rearing duties, and to research in the interrelations of population processes, women's status, and socioeconomic development.

We explore the determinants of domestic violence in two rural areas of Bangladesh. We found increased education, higher socioeconomic status, non-Muslim religion, and extended family residence to be associated with lower risks of violence. The effects of women's status on violence was found to be highly context-specific. In the more culturally conservative area, higher individual-level women's autonomy and short-term membership in savings and credit groups were both associated with significantly elevated risks of violence, and community-level variables were unrelated to violence. In the less culturally conservative area, in contrast, individual-level women's status indicators were unrelated to the risk of violence, and community-level measures of women's status were associated with significantly lower risks of violence, presumably by reinforcing nascent normative changes in gender relations.

Abstract in spanish OBJETIVO: Establecer la hipótesis de que los predisponentes, los facilitadores y los factores de necesidad de los hogares influyen en el estado de vacunación completa de los niños. MATERIAL Y MÉTODOS: Se utilizaron los datos de Bangladesh Demographic and Health Survey de 2004 (N= 3530). Es un estudio descriptivo en el que se utilizó el método de regresión logística múltiple para el análisis de datos. RESULTADOS: Aproximadamente 60% de los niños estaban completa (more) mente inmunizados en zonas rurales de Bangladesh. La tasa de vacunación completa aumentó con un incremento en el intervalo de los nacimientos anteriores y el nivel educativo de la madre. Las mujeres con mejor nivel económico muestran un índice significativamente más alto de probabilidad en el hecho de haber administrado todas las vacunas a sus hijos. La distancia del centro de salud, la paridad, la edad materna, los medios de comunicación, el sexo del niño y la inyección de toxoide tetánico también fueron significativamente asociados de forma positiva con la vacunación completa. CONCLUSIONES: Los resultados reflejan que, independientemente de su necesidad, sólo los niños de los grupos económicos o educativos más altos pueden tener mayores posibilidades de tener el esquema de vacunación completo en zonas rurales de Bangladesh. En otras palabras, los predisponentes, los facilitadores y los factores de necesidad parecen tener una fuerte asociación con la cobertura de inmunización completa. Abstract in english OBJECTIVE: This article establishes the hypothesis that predisposing, enabling and household needs influence the complete vaccination status of children. MATERIAL AND METHODS: Data from the 2004 Bangladesh Demographic and Health Survey (N= 3530) was used. The data was analyzed using descriptive and multiple logistic regression methods. RESULTS: Approximately 60% of the children in rural Bangladesh were fully immunized. The full vaccination rate increased with an increase (more) in the previous birth interval and the education level of the mother. Women with the highest wealth index were significantly more likely to fully immunize their children. Distance from health facility, parity, mother's age, mass media, children's sex and tetanus toxoid injection were also significantly positively associated with full vaccination. CONCLUSIONS: Findings reflect that, irrespective of need, only children from higher economic or educational groups can afford to be fully vaccinated in rural Bangladesh. In other words, predisposing, enabling and need factors appear to have a strong association with full immunization coverage
Arsenic (bio)geochemistry is of intense current interest because the speciation, mobility, and natural chemical processes involving arsenic compounds are intimately related to its bioavailability and a myriad of negative health effects related to arsenic exposure. Arsenic contamination in the environment is wide-spread due to the historical use of arsenic-bearing chemicals in agriculture and industry as well as the occurrence of natural and anthropogenic arsenic-rich waters in such regions as Bangladesh, South America, and the western United States [1–5].
This study aims to describe the status of disclosure practices of corporate sustainability in the annual reports and corporate websites of the banking industry in Bangladesh. It is revealed in the study that, to varying degrees, all listed banks practice sustainability disclosure in an unstructured manner in both the annual reports and corporate websites. The annual report surpasses the corporate website in the disclosure of all categories of corporate sustainability disclosure (CSD) practices except product responsibility disclosure. Unlike the environmental and economic dimensions, issues concerning the social dimension are generally disclosed. Islamic banks disclose more sustainability information in comparison to conventional banks. It is also found that among the three generation, the...

According to the World Health Organization (WHO), more than 50 million people in Bangladesh drink arsenic-laden water, making it the largest case of mass poisoning in human history. Many methods of arsenic removal (mostly using chemical adsorbents) have been studied, but most of these are too expensive and impractical to be implemented in poor countries such as Bangladesh. This project investigates ElectroChemical Arsenic Remediation (ECAR) as an affordable means of removing arsenic. Experiments were performed on site in Bangladesh using a prototype termed “sushi”. This device consists of carbon steel sheets that serve as electrodes wrapped into a cylinder, separated by plastic mesh and surrounded by a tube-like container that serves as a holding cell in which the water is treated electrochemically. During the electrochemical process, current is applied to both electrodes causing iron to oxidize to various forms of iron (hydr)oxides. These species bind to arsenic(V) with very high affi nity. ECAR also has the advantage that As(III), the more toxic form of arsenic, oxidizes to As(V) in situ. Only As(V) is known to complex with iron (hydr)oxides. One of the main objectives of this research is to demonstrate the ability of the new prototype to reduce arsenic concentrations in Bangladesh groundwater from >200 ppb to below the WHO limit of 10 ppb. In addition, varying fl ow rate and dosage and the effect on arsenic removal was investigated. Experiments showed that ECAR reduced Bangladeshi water with an initial arsenic concentration as high as 250 ppb to below 10 ppb. ECAR proved to be effective at dosages as high as 810 Coulombs/Liter (C/L) and as low as 386 C/L (current 1 A, voltage 12 V). These results are encouraging and provide great promise that ECAR is an effi cient method in the remediation of arsenic from contaminated groundwater. A preliminary investigation of arsenic removal trends with varying Coulombic dosage, complexation time and fi ltration methods is also presented.
Limited resources, invested for the development of transport facilities, such as infrastructure and vehicles, coupled with the rapid rise in transport demand, existence of a huge number of non-motorized vehicles on roads, lack of application of adequate and proper traffic management schemes are producing severe transport problems in almost all the urban areas of Bangladesh. Worsening situation of traffic congestion in the streets and sufferings of the inhabitants from vehicle emissions demand extensive research in this field. However, no detailed study concerning traffic congestion and pollution problems for urban areas of Bangladesh has yet been done. Therefore, it has become increasingly important to examine the present state of the problem. This research is a preliminary evaluation of the current situation of traffic pollution problem in Bangladesh. The daily total emissions of NO{sub x}, HC, CO, PM, and SO{sub x} are estimated using the daily fuel consumption and total traffic flows in Dhaka city. Estimated daily emissions are 42, 39, 314, 14, and 42 t/d for NO{sub x}, HC, CO, PM, and SO{sub x}, respectively. The emissions estimated using two different methods revealed good correlation. Daily average concentration of NO{sub x} (NO{sub 2}, NO) were measured at 30 street locations in Dhaka city during September and November, 1996. The results showed extremely high concentrations of NO{sub 2} and NO in these locations.
Andrea Foster uses x-rays to determine the forms of potentially toxic elements in environmentally-important matrices such as water, sediments, plants, and microorganisms. In this free public lecture, Foster will discuss her research on arsenic, which is called the silent killer because dissolved in water, it is colorless, odorless, and tasteless, yet consumption of relatively small doses of this element in its most toxic forms can cause rapid and violent death. Arsenic is a well-known poison, and has been used as such since ancient times. Less well known is the fact that much lower doses of the element, consumed over years, can lead to a variety of skin and internal cancers that can also be fatal. Currently, what has been called the largest mass poisoning in history is occurring in Bangladesh, where most people are by necessity drinking ground water that is contaminated with arsenic far in excess of the maximum amounts determined to be safe by the World Health Organization. This presentation will review the long and complicated history with arsenic, describe how x-rays have helped explain the high yet spatially variable arsenic concentrations in Bangladesh, discuss the ways in which land use in Bangladesh may be exacerbating the problem, and summarize the impact of this silent killer on drinking water systems worldwide.
While the current reform efforts in Bangladesh require a substantive change in how science is taught, an equally substantive change is needed in the culture of professional practice. This study will, therefore, investigate how science teachers' learning in a professional learning community (PLC) influences the ways in which participant teachers learn about, and develop their practice. In so doing, teachers also work towards forming a professional learning community within and across schools. This study presents research from participating teachers' post teaching discussions and subsequent workshop discussions that together comprised their PLC. Data have been drawn from 14 voluntary participant science teachers who were formed into seven peer pairs, from seven schools in Bangladesh. Each pair of teachers was located at the same school. The results indicate that the post teaching discussions and professional workshops offered participating teachers opportunities to discuss their problems regarding resources, content knowledge, pedagogy and the learning environment in the classroom. The findings of this study ultimately carry implications for science teachers' practice and professional learning in secondary schools in Bangladesh, as well as for pre and in-service education for secondary science teachers.

Arsenic is a contaminant in the groundwater of the Ganges delta. In Bangladesh alone, an estimated 57 million people may be drinking water with unsafe arsenic levels. The source of arsenic appears to be natural, solid-phase arsenic in the sediments, and various theories have been put forth regarding the modes of arsenic release to solution, ranging from oxidative or reductive degradation of arsenic-bearing solids to competitive ligand displacement by phosphate. Currently, reductive dissolution of Fe(III) (hydr)oxides and concomitant arsenic release is the most widely accepted explanation of the high arsenic concentrations in groundwater. However, much of the information about potential mechanisms of arsenic release has been gleaned solely from solution-phase data, and many puzzles linger concerning the distribution of arsenic. Only recently have studies been initiated that provide a comprehensive look at microbiology, hydrology, and chemistry of contaminated aquifers in Bangladesh. Using micro-X-ray fluorescence elemental mapping and micro-X-ray absorption near-edge structure spectroscopy, we have detected detrital arsenic-bearing sulfides in the aquifer sediments from our field site in Munshiganj, Bangladesh. The presence of detrital sulfides has been previously discounted, but their presence may, in fact, provide an important source of arsenic. Furthermore, their presence combined with a lack of ferric (hydr)oxides at depth is indicative of the reductive degradation of the latter phase. Rapid abiotic desorption of arsenic from sediments illustrates that a labile arsenic phase is easily transported through the aquifer sands. Addition of ferrihydrite, however, removes arsenic from solution and would minimize transport (a phenomenon not observed within the aquifers of Bangladesh). Based on our results, and in accordance with existing hydrological and biogeochemical data, reductive dissolution of ferric (hydr)oxides transpires in the surface and near-surface environments leaving sediments at well-depths of the Holocene aquifer devoid of such phases. Thus, redox cycling in sediments of the surface and near-surface liberates arsenic which is then transported relatively unimpeded to well-depths through the sandy aquifer.
Arsenic in drinking water is a major public health problem threatening the lives of over 140 million people worldwide. In Bangladesh alone, up to 57 million people drink arsenic-laden water from shallow wells. ElectroChemical Arsenic Remediation(ECAR) overcomes many of the obstacles that plague current technologies and can be used affordably and on a small-scale, allowing for rapid dissemination into Bangladesh to address this arsenic crisis. In this work, ECAR was shown to effectively reduce 550 - 580 mu g=L arsenic (including both As[III]and As[V]in a 1:1 ratio) to below the WHO recommended maximum limit of 10 mu g=L in synthetic Bangladesh groundwater containing relevant concentrations of competitive ions such as phosphate, silicate, and bicarbonate. Arsenic removal capacity was found to be approximately constant within certain ranges of current density, but was found to change substantially between ranges. In order of decreasing arsenic removal capacity, the pattern was: 0.02 mA=cm2> 0.07 mA=cm2> 0.30 - 1.1 mA=cm2> 5.0 - 100 mA=cm2. Current processing time was found to effect arsenic removal capacity independent of either charge density or current density. Electrode polarization studies showed no passivation of the electrode in the tested range (up to current density 10 mA=cm2) and ruled out oxygen evolution as the cause of decreasing removal capacity with current density. Simple settling and decantation required approximately 3 days to achieve arsenic removal comparable to filtration with a 0.1 mu m membrane. X-ray Absorption Spectroscopy (XAS) showed that (1) there is no significant difference in the arsenic removal mechanism of ECAR during operation at different current densities and (2) the arsenic removal mechanism in ECAR is consistent with arsenate adsorption onto a homogenous Fe(III)oxyhydroxide similar in structure to 2-line ferrihydrite. ECAR effectively reduced high arsenic concentrations (100 - 500 mu g=L) in real Bangladesh tube well water collected from three regions to below the WHO limit of 10 mu g=L. Prototype fabrication and field testing are currently underway.

Distance education has emerged out of social compulsion, the dynamics of change and new cultures. It was the failure of traditional systems to be able to meet the demand in countries, where the resources available for tertiary education are limited, which basically gave birth to the new trend of education known as open and distance education. This new and innovative system of education has received a high level of acceptance in different countries as it offers flexible educational opportunities for continuing education to a large segment of their population. The increasing number of older adult learners with varying lifestyles in the population, increasing competitiveness of getting places in tertiary institutions, higher cost of education and a shortage of teachers are the main factors for increasing the popularity of distance education (Duncan, "et al.," 2003). Bangladesh has also taken the opportunity to provide a uniform and mass oriented universal system of education through open and distance education establishing Bangladesh Open University (BOU) in 1992. Objectives of the Study: The main objectives of this study are: (1) to assess the overall status of BOU in comparison with the open universities of two neighboring South Asian countries considering the following aspects: (a) Administrative structural functions; (b) Courses and instructional strategies; (c) Learning opportunities, and (d) Library, laboratory and counselling facilities; (2) to explore the potential of improvement for BOU to enable it to meet the challenges of the country's educational needs in the next millennium.

The study was carried out to review the experience with the existing user-fee (pricing) strategies and examine the socioeconomic and demographic factors associated with payment behaviour among contraceptors in urban Bangladesh for selected contraceptive methods, such as injectables, pill, and condom. Data for the study were drawn from a survey of more than 5,000 married women of reproductive age in Zone 3 of Dhaka city, Bangladesh, within the sample frame of the Urban Panel Survey of the ICDDR,B's former Urban MCH-FP Extension Project. The findings of the study showed that most (80%) urban contraceptors have been paying for selected family-planning services. This indicates the existence of a notable demand for contraceptives which suggests that there is scope for improved financial sustainability of the family-planning programme through charging appropriate user-fees for contraceptives with proper analyses of willingness-to-pay among the contraceptors and price elasticities of demand. Higher socioeconomic status of households, marked by higher levels of education and house rent, and location of residence in non-slum areas, is predictive of paying for contraception. Households having 1-3 living child(ren) are also more likely to make payment for the selected contraceptive services. PMID:11057061
Greenbelts are effective tools for mitigation of traffic induced air and noise pollution. In this study, the potential role of greenbelts along the roadside for the reduction of air pollution and noise levels has been assessed by using seasonally monitored data in a megacity of Bangladesh. Correlation analysis was performed between the vegetation status, measured by canopy density and shelterbelt porosity, and the total suspended particles (TSP) removal percentage. Further, the reduction of noise level was also analyzed. The results showed that the greenbelts greatly contributed to reduce TSP pollution and it was as much as 65%. Noise level reduction was also achieved up to 17dB when compared to the open area. Moreover, TSP removal percentage was correlated to the crown density. Area havin...
Background/objectives:To examine the bacteriological quality of complementary foods (CF) and to correlate the results with diarrhoeal morbidity and nutritional status of Bangladeshi children aged 6–24 months.Subjects/methods:A total of 212 CF samples were tested, of which 72 were collected immediately before the first time of feeding (?1?h of food preparation) and 140 were collected at second/third time of feeding from 140 households located in urban and rural areas of Bangladesh. Anthropometry, food frequency data and demographic information of the children were collected.Results:Of the first time feeding samples, 3% from each of urban and rural areas were found to be contaminated with faecal coliforms (FC) at ?100?CFU/g. E. coli was isolated from 11% and 6...
This article explores whether payment issues or presence of dowry demand in marriage reflecting patriarchal attitude of marital family underlies the positive relationship between dowry and wife abuse using a sample of reproductive-age women (N = 2,702) from a population-based survey conducted in urban and rural Bangladesh in 2001. Regression results show that absence of dowry demand in marriage lowered the likelihood of physical wife abuse in the rural site and its frequency and severity in both sites compared with marriages where dowry was demanded and fully paid. The results suggest that in general, dowry demand predicts the extent, frequency, and severity of physical wife abuse regardless of the status of dowry payment. No payment of dowry increased the likelihood of abuse, its frequency, and severity in households demanding dowry. The direction of association between partial payment of dowry and violence, however, was different in different sites, calling for further research. (Contains 3 tables.)
The South Asian Association for Regional Cooperation (SAARC) was established at the Dhaka summit, Dec 1985, to foster better understanding and economic development through mutual cooperation. The economies of the SAARC countries (India, Pakistan, Nepal, Bhutan, Bangladesh, Sri Lanka, and the Maldives) are at different stages of liberalization and economic reforms with the objective to increase economic development in these countries. To mobilize the financing and transfer of the technology and know-how required for such increased economic development, more emphasis is being given to the role and contribution of the private sector. A summary is presented of a study commissioned by the Asian Development Bank: to review the present status of the mineral sector in the SAARC countries; to identify its potential for further development; and the steps that need to be taken by the governments to promote such development. 171 refs., 12 figs., 9 tabs.
Summary Background Childhood-cancer survival is dismal in most low-income countries, but initiatives for treating paediatric cancer have substantially improved care in some of these countries. The My Child Matters programme was launched to fund projects aimed at controlling paediatric cancer in low-income and mid-income countries. We aimed to assess baseline status of paediatric cancer care in ten countries that were receiving support (Bangladesh, Egypt, Honduras, Morocco, the Philippines, Senegal, Tanzania, Ukraine, Venezuela, and Vietnam). Methods Between Sept 5, 2005, and May 26, 2006, qualitative face-to-face interviews with clinicians, hospital managers, health officials, and other health-care professionals were done by a multidisciplinary public-health research company as a field sur...
Abstract Introduction: We investigated a cluster of patients with encephalitis in the Manikgonj and Rajbari Districts of Bangladesh in February 2008 to determine the etiology and risk factors for disease. Methods: We classified persons as confirmed Nipah cases by the presence of immunoglobulin M antibodies against Nipah virus (NiV), or by the presence of NiV RNA or by isolation of NiV from cerebrospinal fluid or throat swabs who had onset of symptoms between February 6 and March 10, 2008. We classified persons as probable cases if they reported fever with convulsions or altered mental status, who resided in the outbreak areas during that period, and who died before serum samples were collected. For the case?control study, we compared both confirmed and probable Nipah case-patients to contr...
Abstract in spanish La contaminación del agua freática con arsénico en Bangladesh es, hasta la fecha, el mayor caso de envenenamiento de una población registrado en la historia: millones de personas han estado expuestas al arsénico. En este trabajo se describe el descubrimiento en Bangladesh de la contaminación del agua de bebida con arsénico y se recomiendan estrategias para la intervención. A principios de los años setenta se instalaron pozos entubados para abastecer de «agu (more) a pura» y prevenir la morbilidad y mortalidad debidas a las enfermedades gastrointestinales. No se analizó la posible contaminación con arsénico del agua de los millones de pozos entubados que se instalaron porque a la sazón no se tenía conciencia de ese problema. En un estudio realizado en 1998 por el British Geological Survey en 41 distritos se tomaron 2022 muestras de agua; se comprobó que en el 35% de ellas las concentraciones de arsénico superaban los 50 µg/l (valor máximo autorizado en Bangladesh) y en un 8,4% se superaban los 300 µg/l. Sobre la base de la densidad de población de 1998, el British Geological Survey estimó que el número de personas expuestas en Bangladesh a concentraciones de arsénico superiores a los 50 µg/l era de unos 21 millones. Esa cifra prácticamente se duplicaría si se adoptara la concentración máxima de 10 µg/l recomendada por la OMS. Los efectos en la salud de ingerir agua contaminada con arsénico se manifiestan lentamente. Por esa razón, es importante identificar la cifra de personas que en el futuro enfermarán como consecuencia de una exposición pasada y persistente al arsénico, además de la cifra de pacientes que ya han enfermado por esa causa. El periodo de latencia de las lesiones cutáneas provocadas por el arsénico (es decir, el tiempo transcurrido desde la primera exposición hasta la manifestación de la enfermedad), en particular de las queratosis, es por regla general de unos 10 años. El periodo de latencia de los cánceres de la piel e internos es de más de 20 años a partir del momento de la exposición. Los estudios realizados en otros países en los que la población ha estado expuesta largo tiempo a aguas freáticas contaminadas con arsénico indican que una de cada 10 personas que toman agua con 500 µg/l de arsénico pueden acabar muriendo de cánceres causados por el arsénico, en particular de cánceres de pulmón, vejiga y piel. Para responder a esta emergencia de salud pública habría que facilitar una rápida asignación de fondos y la expansión inmediata de las intervenciones actuales. Aunque la exposición al arsénico puede mitigarse de forma relativamente sencilla sin más que suministrar agua exenta de arsénico, la situación en Bangladesh se ve complicada por la debilidad de la economía y por su gran dependencia de la ayuda externa para resolver los problemas de salud pública. Las importantes dificultades que obstaculizan las comunicaciones y el transporte dentro de Bangladesh entorpecen también los programas comunitarios de intervención y educación. No obstante, a diferencia de enfermedades como el paludismo, el cólera o la tuberculosis, que requieren respuestas de salud pública más complejas, la respuesta a la contaminación de los pozos de agua entubados es muy simple: suministrar agua sin arsénico. El arsénico se elimina rápidamente por la orina y, en los casos precoces o leves, no se precisa tratamiento específico. La educación y la participación comunitarias son esenciales para asegurar que las intervenciones tengan éxito, y deben ir acompañadas de un seguimiento que confirme el final de la exposición. Se desconoce la magnitud exacta del problema, pero no por ello es menos necesaria una respuesta de emergencia. La envergadura se podrá determinar en el transcurso de la respuesta. La salud de la población está en riesgo: el socorro no puede esperar a que se realicen más estudios. El descubrimiento de que existen aguas freáticas contaminadas con arsénico en la Argentina, Chile, China, los Estados Unidos de América, la India, México, la República de China (Taiwán), Tailandia y, ahora, Bangladesh evidencia que se trata de un problema mundial. Habría que analizar la presencia de arsénico en todas las aguas subterráneas del mundo que se utilizan para el consumo. Abstract in english The contamination of groundwater by arsenic in Bangladesh is the largest poisoning of a population in history, with millions of people exposed. This paper describes the history of the discovery of arsenic in drinking-water in Bangladesh and recommends intervention strategies. Tube-wells were installed to provide ??pure water?? to prevent morbidity and mortality from gastrointestinal disease. The water from the millions of tube-wells that were installed was not tested (more) for arsenic contamination. Studies in other countries where the population has had long-term exposure to arsenic in groundwater indicate that 1 in 10 people who drink water containing 500 µg of arsenic per litre may ultimately die from cancers caused by arsenic, including lung, bladder and skin cancers. The rapid allocation of funding and prompt expansion of current interventions to address this contamination should be facilitated. The fundamental intervention is the identification and provision of arsenic-free drinking water. Arsenic is rapidly excreted in urine, and for early or mild cases, no specific treatment is required. Community education and participation are essential to ensure that interventions are successful; these should be coupled with follow-up monitoring to confirm that exposure has ended. Taken together with the discovery of arsenic in groundwater in other countries, the experience in Bangladesh shows that groundwater sources throughout the world that are used for drinking-water should be tested for arsenic.
Bangladesh is along the strike of and within a rupture -distance from that enormous M-9.3 earthquake. This country is situated where the India- Sunda subduction zone rises from oceanic depths to subaerial exposure as a result of incipient continent collision where the trench meets the huge sediment accumulation of the Ganges-Brahmaputra Delta (GBD).The Archaean segment between Andaman-Nicobar Island and Bangladesh had been ruptured in the past that have also ruptured the Bangladesh segment. This segment is still active but whether it breaks in great earthquakes in unknown and is a question with complicated hypotheses. Because of huge thickness of sediment comes to Bengal Basin and enters into the subduction zone, this is one of the rare "oceanic" subduction zones where even the deformation front, which is usually along the deep trench, is exposed on land. There have been several active folds, warped reference surfaces and seismicity along the foldbelt for current shortening as high as 1-2 cm/year along Myanmar segment. The range of proposed scenarios for the tectonics of the Myanmar Arc will remain very wide unless new data become available. Among the critical missing data sets are geodetic velocities, crustal structure, active fault kinematics, detailed stratigraphy and precise dating of strata and structures. The GBD traversed by an active plate boundary, yet analyzing how active and whether the motion is aseismic or is taken up by rare earthquakes. From the seismic data, precise modeling of the structural and geodetic foundations for understanding this subaerial subduction zone and accretionary prism have been on the process of better understanding. The modeling will add insight into the mechanical properties of the low-slope overpressured accretionary prism, and possible distributions of locked and creeping active fault segments.
The 26 December 2004 earthquake off Sumatra coast focused world attention on the Sunda arc subduction zone. Bangladesh is along the strike of and within a rupture -distance from that enormous M-9.3 earthquake.

More than 256 major global river basins, which cover about 45% of the continental land surface, are shared among two or more countries. The flow of such a large part of the global runoff across international boundaries has led to tension in many cases between upstream and downstream riparian countries. Among many examples, this is the case of the Ganges and the Brahmaputra Rivers, which cross the boundary between India and Bangladesh. Hydrological data (river discharge, reservoir storage) are viewed as sensitive by India (the upstream country) and are therefore not shared with Bangladesh, which can only monitor river discharge and water depth at the international border crossing. These measurements only allow forecasting of floods in the interior and southern portions of the country two to three days in advance. These forecasts are not long enough either for agricultural water management purposes (for which knowledge of upstream reservoir storage is essential) or for disaster preparedness purposes. Satellite observations of river spatial extent, surface slope, reservoir area and surface elevation have the potential to make tremendous changes in management of water within the basins. In this study, we examine the use of currently available satellite measurements (in India) and in-situ measurements in Bangladesh to increase forecast lead time in the Ganges and Brahmaputra Rivers. Using nadir altimeters, we find that it is possible to forecast the discharge of the Ganges River at the Bangladesh border with lead time 3 days and mean absolute error of around 25%. On the Ganges River, 2-day forecasts are possible with a mean absolute error of around 20%. When combined with optical/infra-red MODIS images, it is possible to map water elevations along the river and its floodplain upstream of the boundary, and to compute water storage. However, the high frequency of clouds in this region results in relatively large errors in the water mask. Due to the nadir altimeter temporal repeat (10 days for current satellites) and to gaps in the water mask, water volume estimates are meaningful only at the monthly scale. Furthermore, this information is limited to channels with wider than 250-500 m. The future Surface Water and Ocean Topography (SWOT) mission, which is intended to be launched in 2020, will provide global maps of water elevations, with a spatial resolution of 100 m and errors on the water elevation equal to or below 10 cm. The SWOT Ka band interferometric Synthetic Aperture Radar (SAR), will not be affected by cloud cover (aside from infrequent heavy rain); therefore, estimation of the water volume change on the Ganges and on the Brahmaputra upstream to the Bangladesh provided by SWOT should be much more accurate in space and time than can currently be achieved. We discuss the implications of future SWOT observations in the context of our preliminary work on the Ganges-Brahmaputra Rivers using current generation satellite data.
In order to reduce the exposure to As naturally occurring in shallow groundwater of the Bengal Basin, tens of thousands of tubewells tapping deeper aquifers of the Bengal Basin have been installed. We address here lingering concerns that As concentrations in deep tubewells might increase over time with monitoring data spanning a period of up to 5 years for 51 community wells, 115-545 ft (34-164 m) deep, installed in Araihazar upazila, Bangladesh. This exceptionally detailed data set shows that all but 4 of these community wells have consistently provided drinking water that meets the Bangladesh standard for As in drinking water of 50 microg L(-1); all but 10 community wells have also consistently met the World Health Organization (WHO) guideline for As of 10 microg L(-1). Groundwater pumped from one third of the community wells does not meet the current WHO guideline for Mn in drinking water of 0.4 mg L(-1), although Mn concentrations are lower than in most surrounding shallow wells. In addition to As and Mn, concentrations of 10 elements (Cr, Ni, Cu, Cd, Ba, Hg, Mo, Sb, Pb, and U) out of a total 19 inorganic constituents of potential health concern were monitored and found to be below their respective guideline values established by WHO. Further study is required to evaluate the health consequences of Mn exposure, but the increase in As concentrations in 4 community wells indicates that all deeper tubewells should be periodically re-tested.

This paper documents the experience of incentive-based reforms in the secondary Islamic/madrasa education sector in Bangladesh within the context of the broader debate over modernization of religious school systems in South Asia. Key features of the reform are changes of the curriculum and policy regarding admission of female students. In return to formal registration and curriculum modernization, madrasas receive financial aid from the government towards teacher salary. Using a cross-sectional census data-set (containing current and retrospective information) on formal secondary schools and madrasas, we first point out that a significant fraction of the existing post-primary registered madrasas today comprises of "converts"; that is, formerly all-male, unregistered religious schools that previously offered traditional, religious education. Furthermore, these madrasas have embraced female students in recent years following the introduction of yet another incentive scheme, namely a conditional cash transfer scheme for secondary girls. Drawing upon school enrolment data aggregated at the region level, we show that regions that had more (modernized) madrasas were more likely to achieve gender parity in secondary enrolment during 1999-2003, holding the number of secular secondary schools constant. This finding highlights the previously undocumented role played by religious schools in removing gender disparity in rural Bangladesh. (Contains 25 notes, 7 tables and 2 figures.)
Abstract in spanish OBJETIVO: Hacer un análisis sobre los pozos y los hogares de la upazila de Araihazar (Bangladesh), a fin de sentar las bases para llevar a cabo un estudio epidemiológico a largo plazo sobre las consecuencias de la exposición crónica a arsénico. MÉTODOS: Durante un periodo de 4 meses de 2000, se obtuvieron muestras de agua a partir de 4997 pozos cercanos que abastecían a una población de 55 000 personas, y se reunieron datos de los hogares próximos; la situación (more) de cada pozo se determinó con una precisión de ± 30 m utilizando receptores del Sistema Mundial de Determinación de la Posición. Las concentraciones de arsénico se analizaron mediante espectrometría de absorción atómica en horno de grafito. Se analizó asimismo la presencia de arsénico en muestras de agua subterránea recogidas cada 2 semanas durante todo un año en seis pozos, empleando para ello la técnica de espectrometría de masas de alta resolución por plasma de acoplación. RESULTADOS: La mitad de los pozos examinados en Araihazar habían sido practicados en los 5 años anteriores, y el 94% eran privados. Sólo un 48% de los pozos suministraban agua con un contenido de arsénico inferior a 50myg/l, el límite fijado actualmente en Bangladesh para el agua potable. Al igual que en otras regiones de Bangladesh y Bengala occidental (India), la concentración de arsénico en Araihazar varía mucho de un lugar a otro (intervalo: 5-860 myg/l), y es por tanto difícil de predecir. Debido a esa variabilidad, sin embargo, casi un 90% de los habitantes vive a menos de 100 m de un pozo salubre. La vigilancia de seis pozos que actualmente se ajustan al límite mencionado de 50 myg/l no reveló ningún dato que sugiriera la existencia de un ciclo estacional de las concentraciones de arsénico paralelo al ciclo hidrológico. Esto lleva a pensar que el cambio de pozos constituye una opción viable en Araihazar, al menos como solución a corto plazo. CONCLUSIÓN: Es preciso fomentar de manera más sistemática el uso de pozos seleccionados en Araihazar y en muchas otras partes de Bangladesh y Bengala occidental (India), y hay que conocer mejor las barreras sociales con que tropieza esa iniciativa para superarlas en la medida de lo posible. Abstract in english OBJECTIVE: To survey tube wells and households in Araihazar upazila, Bangladesh, to set the stage for a long-term epidemiological study of the consequences of chronic arsenic exposure. METHODS: Water samples and household data were collected over a period of 4 months in 2000 from 4997 contiguous tube wells serving a population of 55 000, the position of each well being determined to within ± 30 m using Global Positioning System receivers. Arsenic concentrations wer (more) e determined by graphite-furnace atomic-absorption spectrometry. In addition, groundwater samples collected every 2 weeks for an entire year from six tube wells were analysed for arsenic by high-resolution inductively coupled plasma-mass spectrometry. FINDINGS: Half of the wells surveyed in Araihazar had been installed in the previous 5 years; 94% were privately owned. Only about 48% of the surveyed wells supplied water with an arsenic content below 50 mug/l, the currentBangladesh standard for drinking-water. Similar to other regions of Bangladesh and West Bengal, India, the distribution of arsenic in Araihazar is spatially highly variable (range: 5-860 mug/l) and therefore difficult to predict. Because of this variability, however, close to 90% of the inhabitants live within 100 m of a safe well. Monitoring of six tube wells currently meeting the 50 mug/l standard showed no indication of a seasonal cycle in arsenic concentrations coupled to the hydrological cycle. This suggests that well-switching is a viable option in Araihazar, at least for the short term. CONCLUSIONS: Well-switching should be more systematically encouraged in Araihazar and many other parts of Bangladesh and West Bengal, India. Social barriers to well-switching need to be better understood and, if possible, overcome.
Background: Chronic exposure to arsenic is associated with skin lesions. However, it is not known whether reducing arsenic exposure will improve skin lesions. Objectives: To evaluate the association between reduced arsenic exposures and skin lesion recovery over time. Methods: A follow-up study of 550 individuals was conducted in 2009-2011 on a baseline population of skin lesion cases (N=900) previously enrolled in Bangladesh in 2001-2003. Arsenic in drinking water and toenails, and skin lesion status and severity were ascertained at baseline and follow-up. Logistic regression and generalized estimating equation (GEE) models were used to evaluate the association between log10-transformed arsenic exposure and skin lesion persistence and severity. Results: Water arsenic concentrations decreased in this population by 41% overall, and 65 individuals who had skin lesions at baseline had no identifiable lesions at follow-up. Every log10 decrease in water and toenail arsenic was associated with 22% (odds ratio (OR) = 1.22; 95% CI: 0.85, 1.78) and 4.5 times (OR = 4.49; 95% CI: 1.94, 11.1) relative increase in skin lesion recovery in adjusted models, respectively. Additionally, lower baseline arsenic levels were significantly associated with increased odds of recovery. A log10 decrease in toenail arsenic from baseline to follow-up was also significantly associated with reduced skin lesion severity in cases over time (mean score change = -5.22 units; 95% CI: -8.61, -1.82). Conclusions: Reducing arsenic exposure increased the odds that individual with skin lesions would recover or show less severe lesions within ten years. Reducing arsenic exposure must remain a public health priority in Bangladesh and in other regions affected by arsenic contaminated water. PMID:23060367
ABSTRACT: BACKGROUND: Human cutaneous anthrax results from skin exposure to B. anthracis, primarily due to occupational exposure. Bangladesh has experienced a number of outbreaks of cutaneous anthrax in recent years. The last episode occurred from April to August, 2011 and created mass havoc due to its dreadful clinical outcome and socio-cultural consequences. We report here the clinico-demographic profile and treatment outcome of 15 cutaneous anthrax cases attended at the Dermatology Outpatient Department of Rajshahi Medical College Hospital, Bangladesh between April and August, 2011 with an aim to create awareness for early case detection and management. FINDINGS: Anthrax was suspected primarily based on cutaneous manifestations of typical non-tender ulcer with black eschar, with or without oedema, and a history of butchering, or dressing/washing of cattle/goat or their meat. Diagnosis was established by demonstration of large gram-positive rods, typically resembling B. anthracis under light microscope where possible and also by ascertaining therapeutic success. The mean age of cases was 21.4 years (ranging from 3 to 46 years), 7 (46.7%) being males and 8 (53.3%) females. The majority of cases were from lower middle socioeconomic status. Types of exposures included butchering (20%), contact with raw meat (46.7%), and live animals (33.3%). Malignant pustule was present in upper extremity, both extremities, face, and trunk at frequencies of 11 (73.3%), 2 (13.3%), 1 (6.7%) and 1 (6.7%) respectively. Eight (53.3%) patients presented with fever, 7 (46.7%) had localized oedema and 5 (33.3%) had regional lymphadenopathy. Anthrax was confirmed in 13 (86.7%) cases by demonstration of gram-positive rods. All cases were cured with 2 months oral ciprofloxacin combined with flucoxacillin for 2 weeks. CONCLUSIONS: We present the findings from this series of cases to reinforce the criteria for clinical diagnosis and to urge prompt therapeutic measures to treat cutaneous anthrax successfully to eliminate the unnecessary panic of anthrax.

The second section of this paper set forth a theoretical model relating adolescent growth and development to family formation patterns and their implications for maternal and child health. Subsequent sections of the paper examine the evidence to support specific relationships hypothesized in the model, focusing on longitudinal data from Matlab, Bangladesh. Despite the emphasis on developing country populations, literature from developed countries was also reviewed. The weight of the evidence suggests that in the developed countries, while there is a positive relationship between reproductive maturation and subsequent reproductive behavior, the negative effects of young maternal age on pregnancy outcome is confounded with socioeconomic factors. Teenage pregnancy, or at least teenage birth, occurs disproportionately among the socially and economically disadvantaged. Moreover, teenage childbearing in the U.S., especially when it occurs outside of marriage, violates social norms, at least in the white population. Poor diet may be a problem in the U.S. but it does not appear to result in notable delays in physical growth and development, delayed or compromised adolescent growth, or late age at menarche. Limited evidence suggests that early menarche may be associated with more rapid onset of mature menstrual cycle activity but these findings have not been replicated elsewhere. In developing countries the situation is quite different. First, early marriage and childbearing are desired and common across most segments of society. Second, malnutrition is widespread, and is sufficiently severe to delay the adolescent growth spurt and raise average age at menarche by two to three years compared with developed country populations. This is certainly the case in Bangladesh. In this setting, several observations regarding the relationship of nutritional status, adolescent development and reproduction have been made. First, undernutrition delays growth and reproductive maturation, and women who mature early (i.e., women with young age at menarche) marry at younger ages than later maturers. In addition, body weight appears to have an independent effect on age at marriage, net of age at menarche, such that relatively heavy women marry at younger ages than their lighter counterparts. Explanations for this finding include correlation between body weight and development of secondary sex characteristics, and perhaps a cultural perception that heavier (i.e., normal body weight) women are more attractive, or healthier, mates. The effect of menarche and nutritional status on marriage gives rise to concern that an improvement in nutritional status, and an increase in the age at menarche, would lead to younger marriage and first birth, and higher lifetime fertility.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:8154737
There is an increasing need for strategic global assessments of flood risks in current and future conditions. In this paper, we propose a framework for global flood risk assessment for river floods, which can be applied in current conditions, as well as in future conditions due to climate and socio-economic changes. The framework's goal is to establish flood hazard and impact estimates at a high enough resolution to allow for their combination into a risk estimate. The framework estimates hazard at high resolution (~1 km2) using global forcing datasets of the current (or in scenario mode, future) climate, a global hydrological model, a global flood routing model, and importantly, a flood extent downscaling routine. The second component of the framework combines hazard with flood impact models at the same resolution (e.g. damage, affected GDP, and affected population) to establish indicators for flood risk (e.g. annual expected damage, affected GDP, and affected population). The framework has been applied using the global hydrological model PCR-GLOBWB, which includes an optional global flood routing model DynRout, combined with scenarios from the Integrated Model to Assess the Global Environment (IMAGE). We performed downscaling of the hazard probability distributions to 1 km2 resolution with a new downscaling algorithm, applied on Bangladesh as a first case-study application area. We demonstrate the risk assessment approach in Bangladesh based on GDP per capita data, population, and land use maps for 2010 and 2050. Validation of the hazard and damage estimates has been performed using the Dartmouth Flood Observatory database and damage estimates from the EM-DAT database and World Bank sources. We discuss and show sensitivities of the estimated risks with regard to the use of different climate input sets, decisions made in the downscaling algorithm, and different approaches to establish impact models.
The Visceral Leishmaniasis (VL) Elimination Initiative in the Indian subcontinent was launched in 2005 as a joint effort between the governments in the Region (India, Nepal and Bangladesh) and the World Health Organization (WHO). The objective is to reduce the annual VL incidence below 1/10,000 inhabitants by 2015 based on detection and treatment of VL cases and vector control. We present here a review of studies published in the period 2005-2010 on the efficacy of different tools to control Phlebotomus argentipes. The review indicates that the current indoor residual spraying (IRS) and novel vector control methods mainly insecticide treated nets (ITN) have low effectiveness for several reasons. Efforts to improve quality of IRS operations and further research on alternative and integrated vector control methods need to be promoted to reach the VL elimination target by 2015. PMID:22885260
Objectives Chronic inorganic arsenic (iAs) exposure currently affects tens of millions of people worldwide. To accurately determine the proportion of urinary arsenic metabolites in residents continuously exposed to iAs, we performed arsenic speciation analysis of the urine of these individuals and determined whether a correlation exists between the concentration of iAs in drinking water and the urinary arsenic species content. Methods The subjects were 165 married couples who had lived in the Pabna District in Bangladesh for more than 5?years. Arsenic species were measured using high-performance liquid chromatography and inductively coupled plasma mass spectrometry. Results The median iAs concentration in drinking water was 55??gAs/L (range <0.5?332??gAs/L). Speciation analysis revealed th...
This article attempts to understand the state of teaching, training and research in business ethics in the South and South East Asian region. The countries surveyed are Bangladesh, Bhutan, Cambodia, India, Laos, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand and Vietnam. The diversity across countries in the region is high in terms of economic development, political structuring and human development. The degree of privatization and globalization is varied across countries since each of them is in a different phase of transition. In an earlier survey on Business Ethics, published in 1997, India was the only country from this region that was represented. In the current survey, 12 countries from the South and South East Asia are represented. While Business Ethics in academia is widel...

The paper explores the effects of rapid increases in gender parity in primary schooling in Bangladesh and Malawi on gender inequities in schools and communities. Based on an analysis of comparative case studies of marginalized communities, we argue that educational initiatives focused on achieving gender parity provide limited evidence that girls' educational experiences modeled significantly different gender norms than in communities, or that by being educated, girls experienced a transformation of the inequitable gender relations they faced in society. The data illustrate persistent gender discrimination related to educational attainment and learning, and gender-based violence in schools. These patterns of gendered discrimination and violence largely mirrored those that girls and boys experienced in their homes and communities, raising important questions about the transformational capacity of current gender parity and schooling models.

This paper documents the experience of incentive-based reforms in the secondary Islamic/madrasa education sector in Bangladesh within the context of the broader debate over modernization of religious school systems in South Asia. Key features of the reform are changes of the curriculum and policy regarding admission of female students. In return to formal registration and curriculum modernization, madrasas receive financial aid from the government towards teacher salary. Using a cross-sectional census data-set (containing current and retrospective information) on formal secondary schools and madrasas, we first point out that a significant fraction of the existing post-primary registered madrasas today comprises of 'converts'; that is, formerly all-male, unregistered religious schools that ...
Currently, the most widely accepted hypothesis to explain high As concentrations in Bangladesh groundwaters is that dissolved organic C (DOC) reduces solid Fe (hydr)oxides and mobilizes sorbed arsenate. The nature of the DOC and its release mechanism are still controversial. Based on weekly to biweekly sampling over the course of one monsoon cycle at six monitoring wells of different depths, it is proposed that storativity changes drive natural DOC release from clay-peat layers to the adjacent aquifers. With a decrease in hydraulic heads during the dry season, total mineralization and DOC concentrations increased. With the onset of the rainy season and an increase in hydraulic heads, release of clay-peat derived components stopped and vertical water displacement due to groundwater recharge...
Newborn cord care practices may directly contribute to infections, which account for a large proportion of the four million annual global neonatal deaths. This formative research study assessed current umbilical and skin care knowledge and practices for neonates in Sylhet District, Bangladesh, in preparation for a cluster-randomized trial of the impact of topical chlorhexidine cord cleansing on neonatal mortality and omphalitis.

These included hand-washing, skin and cord care at the time of birth, persons engaged in cord care, cord cutting practices, topical applications ...
Abstract in spanish OBJETIVO: Determinar si la instalación de pozos profundos entubados para reducir la exposición al arsénico subterráneo en zonas rurales de Bangladesh tiene un efecto en la incidencia de la enfermedad diarreica infantil. MÉTODOS: Entre 2005 y 2006, se notificaron los episodios de enfermedad diarreica en niños menores de 5 años que ocurrieron en un día específico de cada mes a los trabajadores sanitarios de la comunidad de seis pueblos rurales. Se utilizó un siste (more) ma de información geográfica que incluye los datos sobre el uso del agua de consumo humano y saneamiento de los pueblos en los que se construyó un pozo de este tipo. Para ello, también se utilizaron los datos obtenidos en un estudio de sistema de posicionamiento global. El sistema de información también incluye datos sanitarios, espaciales y demográficos. Asimismo, se llevó a cabo un estudio de campo para determinar si existían hogares que obtuvieron agua potable de pozos profundos instalados en 2005. El efecto del uso de pozos profundos entubados en la incidencia de la diarrea infantil se evaluó utilizando un modelo de regresión binomial negativa con efectos aleatorios. RESULTADOS: El riesgo de diarrea infantil fue un 46% inferior en 179 hogares que utilizaron un pozo profundo entubado en comparación con los 364 hogares que utilizaron un pozo poco profundo entubado (P=0,032). Ni el estado socioeconómico, el número de letrinas, la densidad de población, ni el año del estudio influyeron significativamente en el riesgo de la enfermedad. La incidencia de la diarrea infantil descendió drásticamente entre el año 2005 y el año 2006, independientemente de la fuente de agua. CONCLUSIÓN: Con la introducción de los pozos profundos entubados para reducir el arsénico en el agua potable de las zonas rurales de Bangladesh se obtuvo el beneficio adicional de reducir la incidencia de la diarrea en niños de corta edad. Abstract in english OBJECTIVE: To determine whether the installation of deep tube wells to reduce exposure to groundwater arsenic in rural Bangladesh had an effect on the incidence of childhood diarrhoeal disease. METHODS: Episodes of diarrhoeal disease in children aged under 5 years that occurred on one specified day each month between 2005 and 2006 were reported to community health workers for six rural villages. A geographical information system containing details of household water use a (more) nd sanitation in the villages was built using data obtained by a global positioning system survey. The information system also included health, spatial and demographic data. A field survey was carried out to determine whether households obtained drinking water from deep tube wells installed in 2005. The effect of deep tube well use on the incidence of childhood diarrhoea was assessed using a random effects negative binomial regression model. FINDINGS: The risk of childhood diarrhoea was 46% lower in the 179 households that used a deep tube well than in the 364 that used a shallow tube well (P = 0.032). Neither socioeconomic status, latrine density, population density nor study year had a significant influence on disease risk. The incidence of childhood diarrhoea declined dramatically between 2005 and 2006, irrespective of water source. CONCLUSION: The introduction of deep tube wells to reduce arsenic in drinking water in rural Bangladesh had the additional benefit of lowering the incidence of diarrhoea among young children.

The document is developed as part of the Development, Energy and Climate project in order to facilitate methodological consistency and the use of common assumptions in national case studies in Bangladesh, Brazil, China, India, Senegal and South Africa that are conducted as part of the project. In addition to this document the project and country studies are also based on in depth thematic work in three areas namely; 1) Development pathways and climate change; 2) Assessment of Policy Instruments in the Context of Current Market Structure, Institutional Capacities and Risks in Developing Countries; 3) Climate change impacts, vulnerability, and adaptation in the energy sector with a special emphasis given to linkages between adaptation and mitigation policies. The Development, Energy, and Climate project will identify promising energy policy options in the participating countries that are consistent with their national sustainable development objectives. The project teams from Bangladesh, Brazil, China, India, South Africa and Senegal will examine how energy sector policies can be evaluated using specific sustainable development indicators and existing analytical approaches and tools relevant to the countries. The country studies will address energy sector issues, adaptation policies, and alternative scenarios for technology penetration processes. The policy options and the sustainable development impacts of implementing these will be discussed in national stakeholder dialogues with broad participation of government, private sector and NGOs. Cross-country interactions about conceptual and common methodological issues will be covered in three thematic papers. The project will produce a synthesis of the country case studies as an input to various international processes in order to build support for approaches that integrate sustainable development, energy and climate policies.

Although health interventions start with good intentions to develop services for disadvantaged populations, they often distort the health market, making the delivery or financing of services difficult once the intervention is over: a condition called the 'Develop-Distort Dilemma' (DDD). In this paper, we describe how to examine whether a proposed intervention may develop or distort the health market. Our goal is to produce a tool that facilitates meaningful and systematic dialogue for practitioners and researchers to ensure that well-intentioned health interventions lead to productive health systems while reducing the undesirable distortions of such efforts. We apply the DDD tool to plan for development rather than distortions in health markets, using intervention research being conducted under the Future Health Systems consortium in Bangladesh, China and Uganda. Through a review of research proposals and interviews with principal investigators, we use the DDD tool to systematically understand how a project fits within the broader health market system, and to identify gaps in planning for sustainability. We found that while current stakeholders and funding sources for activities were easily identified, future ones were not. The implication is that the projects could raise community expectations that future services will be available and paid for, despite this actually being uncertain. Each project addressed the 'rules' of the health market system differently. The China research assesses changes in the formal financing rules, whereas Bangladesh and Uganda's projects involve influencing community level providers, where informal rules are more important. In each case, we recognize the importance of building trust between providers, communities and government officials. Each project could both develop and distort local health markets. Anyone intervening in the health market must recognize the main market perturbations, whether positive or negative, and manage them so as to maximize the benefits to the health system and population health.

Marine sediments offshore Bangladesh are mainly supplied by the Ganges-Brahmaputra river system and are accumulated on the shelf of Bangladesh. The average sediment discharge of the world's biggest river system is estimated to be 0.8-1 billion tons per year. The shallow shelf is cut by a steep and up to 1000 m deep anaerobic canyon, called the "Swatch of No Ground", which acts as a sediment trap. An extremely high annual sedimentation flux of 20-45 cm was determined for the last 50 years by 137Cs and 210Pb measurements. In order to investigate the sediment transport in the Bay of Bengal a marine sediment core was taken from the mid-part of the Swatch of No Ground (21°18N/89°34E) and analyzed for element composition and grain-size distributions. Results show a sequence of graded fine-sand-silt-clay layers. These sequences can be directly related to the historical record of tropical storms, which move across the northern Bay of Bengal during pre- and post-monsoon flood peak and mobilize huge amounts of the shallow marine and coastal sediments into turbid hyperpycnal water masses. Due to the anti-clockwise rotation of the cyclones and their northward path the main transport direction is westward. The coarse grained sediment, remobilized by storm waves, is supported by cyclone-induced currents toward the canyon while the fine grained fraction follows afterward supported by the storm swell plus the semi-diurnal tidal component. Despite the high riverine input the amount of sediment mobilized during normal weather conditions is minimal compared to the sediment mobilized by the cyclonic high-energy input. Similar cyclone-induced sediment transport probably also governs erosion and deposition in most tropical shelf areas affected by the monsoon regime.
Research has demonstrated that cholera epidemics in Bangladesh occur seasonally. This bimodal outbreak pattern closely follows times when large monsoon events are most frequent (spring and fall). While these patterns are presented in regional data, this knowledge alone cannot forecast the severity and location of cholera outbreaks until a monsoon event occurs, or an outbreak is reported. Therefore, there can only be reactive responses to cholera outbreaks. A heightened understanding of the link between environmental factors and outbreak occurrence will greatly enhance disease management capabilities. A predictive tool capable of giving an advanced warning of the environmental hazards that lead to location specific outbreaks allows for proactive and preventative responses, minimizing negative effects. A specific goal of this research was to relate latitude-longitude data with existing points associated with V. cholerae human case data collected from four cities in Bangladesh. Remotely sensed products were used to better understand the correlation between human outbreak occurrences, chlorophyll-a estimates, sea surface temperature (SST), and rainfall. Using MODIS, SeaWiFS, and TRMM satellite data, a gridded regional image was developed. Correlation analyses of the data were studied within the context of geographically diverse locations for the four cities of interest. Seasonal relationships were found between the cholera case data and all three of the chosen remotely sensed parameters. The strongest correlation found was between chlorophyll-a concentrations and reported human cases. The primary deliverable of this project was the production of an interactive Google Earth base map for use in a pilot design study that will lead to the development of applications to connect earth science products with water and health studies. The base map, with its inherent value of merging remotely sensed data with in situ observation points, can be used as a basis for constructing better models of disease outbreaks. This effort will build upon current research at University of Maryland, College Park, which focuses on the impacts of climate on both water and health.
Electrocoagulation (EC) using iron electrodes is a promising arsenic removal strategy for Bangladesh groundwater drinking supplies. EC is based on the rapid in situ dissolution of a sacrificial Fe(0) anode to generate iron precipitates with a high arsenic sorption affinity. We used X-ray absorption spectroscopy (XAS) to investigate the local coordination environment (Fe and As in EC precipitates generated in synthetic Bangladesh groundwater (SBGW). Fe and As K-edge EXAFS spectra were found to be similar between samples regardless of the large range of current density (0.02, 1.1, 5.0, 100 mA/cm(2)) used to generate samples. Shell-by-shell fits of the Fe K-edge EXAFS spectra indicated that EC precipitates consist of primarily edge-sharing FeO(6) octahedra. The absence of corner-sharing FeO(6) octahedra implies that EC precipitates resemble nanoscale clusters (polymers) of edge-sharing octahedra that efficiently bind arsenic. Shell-by-shell fits of As K-edge EXAFS spectra show that arsenic, initially present as a mixture of As(III) and As(V), forms primarily binuclear, corner-sharing As(V) surface complexes on EC precipitates. This specific coordination geometry prevents the formation of FeO(6) corner-sharing linkages. Phosphate and silicate, abundant in SBGW, likely influence the structure of EC precipitates in a similar way by preventing FeO(6) corner-sharing linkages. This study provides a better understanding of the structure, reactivity, and colloidal stability of EC precipitates and the behavior of arsenic during EC. The results also offer useful constraints for predicting arsenic remobilization during the long-term disposal of EC sludge. PMID:22132945

Malaria transmission in many part of the world specifically in Bangladesh and southern African countries is unstable and epidemic. An estimate of over a million cases is reported annually. Malaria is heterogeneous, potentially due to variations in ecological settings, socio-economic status, land cover, and agricultural practices. Malaria control only relies on treatment and supply of bed networks. Drug resistance to these diseases is widespread. Vector control is minimal. Malaria control in those countries faces many formidable challenges such as inadequate accessibility to effective treatment, lack of trained manpower, inaccessibility of endemic areas, poverty, lack of education, poor health infrastructure and low health budgets. Health facilities for malaria management are limited, surveillance is inadequate, and vector control is insufficient. Control can only be successful if the right methods are used at the right time in the right place. This paper aims to improve malaria control by developing malaria risk maps and risk models using satellite remote sensing data by identifying, assessing, and mapping determinants of malaria associated with environmental, socio-economic, malaria control, and agricultural factors.
Based on the regional setting, five petroleum-geological provinces can be distinguished in Bangladesh: Himalayan Foredeep in the northwest, Stable Shelf, Hinge Zone and Bengal Foredeep in the central and southern part of the country and the Fold Belt in the east and southeast; the southeastern Fold Belt and the Bengal Foredeep extend into the offshore area. The Himalayan Foredeep is in its early stage of exploration, drilling in the Stable Shelf, Hinge and Foredeep area so far has been commercially unsuccessful; the Fold Belt comprises the proven gas province of the Surma Basin in the northeast and the Chittagong Hill Tracts are judged as oil and gas prospective. Commencing with a brief account on the exploration history, the individual provinces are commented upon from the petroleum-geological point of view, according to the stage of knowledge, special emphasis is given to the Stable Shelf/Hinge area as well as to the Surma Basin including speculative considerations on the quantity of generated hydrocarbons. - Status of the paper is early 1986.

Background/objectives:To examine the bacteriological quality of complementary foods (CF) and to correlate the results with diarrhoeal morbidity and nutritional status of Bangladeshi children aged 6-24 months.Subjects/methods:A total of 212 CF samples were tested, of which 72 were collected immediately before the first time of feeding (?1?h of food preparation) and 140 were collected at second/third time of feeding from 140 households located in urban and rural areas of Bangladesh. Anthropometry, food frequency data and demographic information of the children were collected.Results:Of the first time feeding samples, 3% from each of urban and rural areas were found to be contaminated with faecal coliforms (FC) at ?100?CFU/g. E. coli was isolated from 11% and 6% of samples, and B. cereus from 8% and 6% of samples from urban and rural areas, respectively. In contrast, 33% of the second/third time feeding samples from urban areas and 19% from rural areas were contaminated with FC at ?100?CFU/g (Pfood preparation practices. Consumption of contaminated CF appeared to be associated with a higher frequency of diarrhoea and malnutrition in children. PMID:22805495
Research has documented that, around the world, women who are childless against their will suffer from an array of social, economic and emotional difficulties. The causes of this suffering are primarily related to their gender position in society and their gender identity. This paper addresses the impact of class differences on the gender-related suffering of childless women in the socially very hierarchically structured society of Bangladesh. The main method was gathering life histories of illiterate rural poor childless women and educated urban middle-class childless women. The rural childless women experience strong stigma in society, as their identity is devalued due to their inability to produce children. As a result, they suffer from feelings of guilt, role failure, loss of self-esteem, abandonment by the family, social isolation, and impoverishment. In contrast, because of their relatively high socio-economic status and good educational background, urban childless women have more opportunities to avail themselves of alternative social identities and thus avoid social isolation. Despite these differences, both groups of women lead frustrated lives, burdened with a deep sense of guilt for not being able to produce children. PMID:22060126
This study used data from the Bangladesh Adolescents Survey 2005 to identify socioeconomic and urban-rural determinants of knowledge regarding sexually transmitted infections (STIs) including HIV/AIDS transmission. A cluster sampling of 11 986 adolescents was conducted from April to August 2005. Data were analyzed using SPSS applying principle component analysis, multivariate logistic regression analysis, and prevalence ratios (PRs) with 95% confidence intervals (CIs). Overall knowledge of transmission of STIs was poor (4.5%), showing urban adolescents having twice the knowledge of rural adolescents (PR = 1.9; 95% CI = 1.6-2.2). HIV/AIDS knowledge level was high (68%), with a 40% higher knowledge among urban adolescents (PR = 1.4; 95% CI = 1.3-1.4). Probability of knowledge of STIs and HIV/AIDS transmission was lowest in 12- to 14-year-old uneducated female household workers of the poorest socioeconomic status in rural settings (0.0002 and 0.064, respectively). The urban-rural factor was more important than the socioeconomic factor. Health promotion and education programs can play an important role in improving the sexual reproductive health knowledge situation. PMID:21980146
Predictions regarding the possible effects of global warming on Bangladesh`s climate are uncertain. However, the predictions for 2030 made by four General Circulation Models all suggest that there might be increased precipitation, with estimates ranging between 5 and 100% increases in rainfall. Increases of these magnitudes, if they were to occur, would have significant implications for agriculture, flooding, river sediment loads, and flood protection works. Increased flooding of the coastal areas of countries like Bangladesh is a possibility, and enormous health and economic distress and human suffering may follow. With the change in temperature, there may be unpredictable change in bacterial and viral morphology with health hazards of unpredictable limits. It has been estimated that a 100 cm rise in sea level in the Bay of Bengal would result in 12--18% of land areas of Bangladesh being lost to the sea, including most of the Sundarbans. Although it is difficult to predict the timing and magnitude of all the global changes including sea-level rise, climate change, etc., it is anticipated that one of the most serious consequence for Bangladesh would be the reduction of already minimal land: person ratio and consequently exacerbating pressure on the remaining natural resources. Bangladesh is in favor of an international agreement for assistance to vulnerable countries like Bangladesh to take necessary preparations and adopt measures to survive a sea-level rise, climate change, increased flooding, and more frequent storm surges.
BACKGROUND: Dietary pattern analysis is emerging as a practical, effective tool for relating comprehensive dietary intake to risk of cardiovascular disease mortality. However, no studies have applied this technique to a population outside of the developed world. METHODS: We conducted prospective cohort analyses in 11,116 participants enrolled in the Health Effects of Arsenic Study in Araihazar, Bangladesh, measuring deaths attributable to disease of circulatory system, heart disease, and cerebrovascular disease. Participants were enrolled in 2000 and followed up for an average of 6.6years. Dietary information was obtained through a previously validated food-frequency questionnaire at baseline. RESULTS: Principal component analysis based on our comprehensive, 39 item FFQ yielded 3 dietary patterns: (i) a "balanced" pattern, comprised of steamed rice, red meat, fish, fruit and vegetables; (ii) an "animal protein" diet, which was more heavily weighted towards eggs, milk, red meat, poultry, bread, and vegetables; and (iii) a "gourd and root vegetable" diet that heavily relied on a variety of gourds, radishes, pumpkin, sweet potato, and spinach. We observed a positive association between increasing adherence to the animal protein diet and risk of death from both disease of the circulatory system and heart disease; the hazard ratios were 1.13 (95% CI, 1.00-1.28, p=0.05) and 1.17 (95% CI, 0.99-1.38, p=0.07), respectively, in relation to one standard deviation increase in the factor scores for the animal protein diet pattern, after controlling for age, sex, body mass index, smoking status, and energy intake. The positive association was more significant among ever smokers; the hazard ratios (95% CI) for deaths from disease of the circulatory system and heart disease were 1.17 (1.02-1.34) and 1.20 (1.00-1.45), respectively, in relation to one standard deviation increase in the factor scores for the animal protein diet pattern. CONCLUSIONS: An animal protein-rich diet in rural Bangladesh may increase risk of heart disease mortality, especially among smokers. This emphasizes the need to further explore and address the impact of dietary patterns on cardiovascular disease in populations undergoing epidemiologic transition. PMID:22560940
Abstract in spanish OBJETIVO: Determinar si el programa Dinero por Trabajo mejoró el estado nutricional de las mujeres y los niños más desfavorecidos de las zonas rurales de Bangladesh durante un periodo de un año de inseguridad alimentaria. MÉTODOS: El estudio de cohortes comprendió una muestra aleatoria de 895 hogares, de entre los más de 50 000 inscritos en el programa Dinero por Trabajo, entre septiembre y diciembre de 2007, y 921 hogares de características similares como grupo d (more) e control. En cada hogar se midieron la altura, el peso y la circunferencia braquial de una mujer y de un niño menor de 5 años al inicio y al final del estudio (duración media: 10 semanas). En ambas ocasiones, las mujeres informaron sobre los gastos y el consumo alimentarios semanales de sus hogares. Se compararon los cambios paramétricos existentes en los dos grupos. RESULTADOS: Al inicio del estudio no se observó ninguna diferencia significativa entre los grupos. Al final del estudio, la diferencia en la circunferencia media braquial entre las mujeres del grupo de intervención y el de control había aumentado 2,29 mm y la diferencia en el peso medio era de 0,88 kg. Entre los niños, la diferencia de las medias entre los dos grupos también había aumentado a favor del grupo de intervención: altura (0,08 cm, p Abstract in english OBJECTIVE: To determine whether a cash-for-work programme during the annual food insecurity period in Bangladesh improved nutritional status in poor rural women and children. METHODS: The panel study involved a random sample of 895 households from over 50 000 enrolled in a cash-for-work programme between September and December 2007 and 921 similar control households. The height, weight and mid-upper arm circumference of one woman and child aged less than 5 years from each (more) household were measured at baseline and at the end of the study (mean time: 10 weeks). Women reported 7-day household food expenditure and consumption on both occasions. Changes in parameters were compared between the two groups. FINDINGS: At baseline, no significant difference existed between the groups. By the study end, the difference in mean mid-upper arm circumference between women in the intervention and control groups had widened by 2.29 mm and the difference in mean weight, by 0.88 kg. Among children, the difference in means between the two groups had also widened in favour of the intervention group for: height (0.08 cm; P
The water hyacinth project was initially proposed at the Regional Workshop on Rural Technology held at Dacca in January 1978. In November 1978, national coordinators met at New Delhi and outlined the project in detail as reported in CSC(79)RT-4. The meeting was attended by delegates from Bangladesh, Egypt, Guyana, India, Malaysia, Papua New Guinea, Sri Lanka, Commonwealth Science Council and the United Nations Environment Programme. Following this a proposal was submitted to UNEP seeking funding support to meet the external cost component of the project. This support was subsequently granted. The project aims to achieve an integrated approach towards managing water hyacinth. The underlying intention was that management would cover both eradication of the plant as well as making productive use of it when possible. Productive uses envisaged include biogas synthesis, production of papers and boards and as a source of proteins. Another interesting possibility is the use of the plant to control industrial as well as domestic water pollution . All these were detailed in a three and a half year time plan. The project had its first review meeting in June 1979 in Papua New Guinea. The major intention of this meeting was to examine status reports from each country in an attempt to quantify the problem caused by water hyacinth and assess the work plan in relation to this. The report of this meeting has been published as CSC(79)RT-5. At this meeting Papua New Guinea decided to withdraw from this project as water hyacinth was not regarded as a severe problem. The use of dugong as a control agent was not recommended by Papua New Guinea. In April 1980 an interim review meeting attended by the Regional Coordinator and representatives of UNEP and CSC was held in London where, based on the progress made in the participating countries, activities and time schedules were refined and sharpened (CSC (80)RT-16). It look some time to resolve the external funding question . It was therefore decided that January 1980 should be regarded as the formal date of launching for the project. Australia, Bangladesh, Fiji, India, Malaysia and Sri Lanka are actively participating in the project at the present time with India providing overall technical coordination. This report summarizes progress as at 31 December 1980, it is based on reports received from national project coordinators. Information and results emerging from the different participating countries are very encouraging and they strengthen the hope that technically, environmentally and economically feasible solutions can be found for managing water hyacinth. A review of progress in each of the participating countries follows.
Abstract in spanish Una revisión preliminar de Polygalaceae en el subcontinente indio ha sido preparada sobre la base de la observación de diferentes especies pertenecientes a esta familia en un hábitat natural y el análisis de especímenes de herbario y de literatura taxonómica. En el subcontinente indio (Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka e India) la familia Polygalaceae está pobremente representada (6,37% de la distribución global). Este artículo trata la (more) distribución, fitoendemismo, posibles fósiles ancestrales, potencial económico y riesgos de supervivencia de especies existentes. El estado actual de fitoendemismo en Polygalaceae en el subcontinente indio (35,29% en 2002-2007) ha sido comparado con la información de investigaciones anteriores (21,87% en 1939-1940) finalizadas en el siglo XX. El aumento de la tasa de endemismo indica un incremento en el número de especies endémicas o un lapso de decrecimiento de especies pan-endémicas pertenecientes a esta familia. Para una mejor comprensión de los aspectos funcionales del porcentaje dinámico de las especies, la tasa de endemismo de un grupo determinado ha sido usada aquí como un indicador clave. El crecimiento en una misma zona geográfica ha sido registrado en intervalos de tiempo diferente y posteriormente es considerado para narrar los estudios académicos en la forma de presupuestos económicos de recursos renovables para asegurar su conservación y uso sostenible. Abstract in english A preliminary checklist of Polygalaceae in Indian subcontinent has been prepared on the basis of primary observations of different taxa belonging to this family in wild habitats and on secondary observations based on examined herbarium specimens and taxonomic literature. On the Indian subcontinent (comprising Bangladesh, Bhutan, Myanmar, Nepal, Pakistan, Sri Lanka and India), the family Polygalaceae is poorly represented (6.37% of global distribution). The present pap (more) er deals with a brief review of distribution, phytoendemism, possible fossil ancestry, economic potential and survival threat on existing taxa. The present status of phytoendemism of Polygalaceae in Indian subcontinent (35.29% in 2002-2007) has been compared to the data of previous investigations (21.87% in 1939-1940) done in the XX century. The increasing rate of endemism either indicates towards increasing number of endemic taxa or decreasing span of distribution of pan-endemic taxa belonging to this family. For a better understanding of the functional aspects of species dynamics the percentage of rate of endemism of a particular group of plants has been used as key index here. The growing on same geographical location has been recorded in different time intervals and has further been considered to narrate the academic studies in form of qualitative economic appraisal of renewable resources for ensuring its conservation sustainable utilization.
The allelopathic potential of 102 Bangladesh rice cultivars (60 traditional and 42 high yielding) against four test plant species, cress (Lepidium sativum L.), lettuce (Lactuca sativa L.), barnyardgrass (Echinochloa crus-galli (L.) Beauv) and Echinochloa colonum (L.) Link was determined for shoot and root growth. In the two-way analysis of variance, the effect of rice cultivar, test plant species and their interactions were significant (PE. colonum. The present research suggests that BR17 is the most allelopathic among 102 Bangladesh rice cultivars and may be one of the candidates for research on Bangladesh rice allelopathy for isolation and identification of allelochemicals.

Tobacco use and secondhand smoke (SHS) exposure in reproductive-aged women can cause adverse reproductive health outcomes, such as pregnancy complications, fetal growth restriction, preterm delivery, stillbirths, and infant death. Data on tobacco use and SHS exposure among reproductive-aged women in low- and middle-income countries are scarce. To examine current tobacco use and SHS exposure in women aged 15-49 years, data were analyzed from the 2008-2010 Global Adult Tobacco Survey (GATS) from 14 low- and middle-income countries: Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay, and Vietnam. The results of this analysis indicated that, among reproductive-aged women, current tobacco smoking ranged from 0.4% in Egypt to 30.8% in Russia, current smokeless tobacco use was tobacco smoking prevalence in some countries suggests that strategies promoting cessation should be a priority, whereas low prevalence in other countries suggests that strategies should focus on preventing smoking initiation. Promoting cessation and preventing initiation among both men and women would help to reduce the exposure of reproductive-aged women to SHS. PMID:23114255
A brief, vivid portrait of the human rights conditions for women in Asia was presented: "kapit sa patalim" or utter despair, urban migration, export processing zones, tourism and prostitution, political repression, and military sexual slavery. Advocates of women's human rights for Asian women must contend with patriarchal and male-dominated systems that oppress and exploit women to a much greater extent than men. Liberation from these systems and the domination and exploitation by wealthier nations must be a goal of a new economic world order. Unjust and repressive structures must be destroyed, and equitable distribution of wealth and democracy and popular initiatives promoted. The status of women must be raised to coequal status with men. The most important objective of human rights advocates should be the empowerment of women at the individual, community, national, regional, and international level. The Asian Women's Human Rights Council was established as an addition to 3 already operating regional commissions of women's organizations. The aim was not just to describe women as victims, but to pressure development activity to account for women's human rights. Sex tribunals have been scheduled between 1993 and 1994 to address the following issues: 1) sex trafficking (Japan, May 1993); 2) violence against women (Pakistan, December 1993); 3) militarism, environment, and violence against women (Korea, March 1994); 4) crimes of development against women in Asia (India); 5) religion and violence against women (Malaysia, 1994); and 6) indigenous women (December 1994). Women were victims when Filipino domestic workers were stranded and raped in Iraq during the chaos of war, when girls from landless peasant families migrated near Clark Air Force Base to earn a living as prostitutes for US servicemen, when women were forced to work 36-hour shifts in foreign-owned garment factories in Bataan, when women migrated for work, and when women were abused and battered in Bangladesh and India. Many other examples of abuse were indicated in the discussion. PMID:12345217
The present invention comprises a decentralized coordination strategy called alpha-beta coordination. The alpha-beta coordination strategy is a family of collective search methods that allow teams of communicating agents to implicitly coordinate their search activities through a division of labor based on self-selected roles and self-determined status. An agent can play one of two complementary roles. An agent in the alpha role is motivated to improve its status by exploring new regions of the search space. An agent in the beta role is also motivated to improve its status, but is conservative and tends to remain aggregated with other agents until alpha agents have clearly identified and communicated better regions of the search space. An agent can select its role dynamically based on its currentstatus value relative to the status values of neighboring team members. Status can be determined by a function of the agent's sensor readings, and can generally be a measurement of source intensity at the agent's current location. An agent's decision cycle can comprise three sequential decision rules: (1) selection of a current role based on the evaluation of the currentstatus data, (2) selection of a specific subset of the current data, and (3) determination of the next heading using the selected data. Variations of the decision rules produce different versions of alpha and beta behaviors that lead to different collective behavior properties.

As part of its growth strategy, Bangladesh instituted a trade liberalization process in the early 1990s which gained momentum in later years. Trade grew from 24.4 to 45% of GDP between 1980???81 and 2007???08, an indicator of increased liberalization as well as the growing importance of the external sector in Bangladesh. Apart from its unilateral liberalization, Bangladesh participates in three different regional trade agreements (RTAs): the South Asian Free Trade Agreement (SAFTA), the Asia Pacific Trade Agreement (APTA) and the Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation Free Trade Area (BIMSTEC FTA). In addition, Bangladesh signed preferential trade agreements (PTAs) with the member countries of the Developing 8 (D8). Because of the growing importance o...

Researchers have invented a material called ARUBA -- Arsenic Removal Using Bottom Ash -- that effectively and affordably removes arsenic from Bangladesh groundwater. Through analysis of studies across a range of disciplines, observations, and informal interviews conducted over three trips to Bangladesh, we have applied mechanical engineering design methodology to develop eight key design strategies, which were used in the development of a low-cost, community-scale water treatment system that uses ARUBA to removearsenic from drinking water. We have constructed, tested, and analysed a scale version of the system. Experiments have shown that the system is capable of reducing high levels of arsenic (nearly 600 ppb) to below the Bangladesh standard of 50 ppb, while remaining affordable to people living on less than US$2/day. The system could be sustainably implemented as a public-private partnership in rural Bangladesh.
The potential of grid-connected solar PV system in Bangladesh was estimated utilizing GeoSpatial toolkit, NASA SSE solar radiation data and HOMER optimization software. Financial viability of solar photovoltaic as an electricity generation source for Bangladesh was also assessed utilizing a proposed 1-MW grid-connected solar PV system using RETScreen simulation software for 14 widespread locations in Bangladesh. The technical potential of gird-connected solar PV in Bangladesh was calculated as about 50174 MW. The annual electricity generation of the proposed system varied depending on the location between 1653 MWh and 1854 MWh, with a mean value of 1729 MWh. Several different economic and financial indicators were calculated, such as the internal rate of return, net present value, benefit-...
Four different data sources have been compared with respect to observations of the annual water storage variations in the region of Bangladesh. Data from satellite altimeters and river gauges estimates the variation in surface water storage in the major rivers of Bangladesh. The GRACE satellites measure the integrated mass change and hence the terrestrial soil moisture variations, which can also be estimated by a hydrological model (GLDAS). These types of observations enable the derivation of the integrated water storage in the entire region of Bangladesh. For all data types, the annual signal has been estimated from a common dataset spanning the period 2003 and 2004. All four different data observe that water storage in Bangladesh is largely dominated by an annual signal with a phase peaking in early September. The annual variations in river level peaks roughly two weeks earlier than terrestrial soil moisture observations by GRACE observations and GLDAS model output.

This paper investigates the development of corporate governance regulations in emerging economies, using the case of Bangladesh. In particular, the paper considers three issues: What type of corporate governance model may be suitable for an emerging economy such as Bangladesh? What type of model has Bangladesh adopted in reality? and What has prompted such adoption? By analysing the corporate environment and corporate governance regulations, the paper finds that, like many other developing nations, Bangladesh has also adopted the Anglo-American shareholder model of corporate governance. Analysis of behaviours of principal actors in the Bangladeshi corporate governance scenario, using new institutionalism as a theoretical foundation, then reveals that such adoption may be prompted by exposu...
Studies have found that general use of Facebook influences subjective well-being. However, fewer studies have explored the impact of specific use behaviors, such as information posted in status updates. The current study uses data collected from 251 Facebook-using undergraduate students through an online survey, and examines the valence and frequency of Facebook status updates as predictors of three measures of subjective well-being: life satisfaction, physical health, and depression. Valence and frequency of status updates strongly predict the tendency to ruminate, and rumination mediates the effects of positive and negative status update frequency on subjective well-being. Results support the conclusion that rumination mediates the impact of Facebook status updates on subjective well-being more strongly than Facebook status updates mediate the impact of rumination on subjective well-being.

The coastal areas of the Bay of Bengal along the Ganges-Brahmaputra (GB) delta are low-lying and highly vulnerable to natural disasters, such as flooding and cyclones. The modern GB delta was formed within the large Bengal basin during the last 11,000 years, and it extends offshore in the Bay of Bengal. The coastal areas of this delta harbor the world’s largest continuous patch of mangrove forests, the Sundarbans, covering approximately one million hectares, ~60% of which is in Bangladesh and the rest is in India. Studies have shown that the GB delta is still undergoing accretion at a rate of up to 1.1 cm per year. But remote sensing studies have also indicated that the shoreline and shallow offshore areas of the western delta front are currently in a net erosional state at a rate of about 1.9 square km per year, with a coastline retreat of as much as 3-4 km since 1792. Other studies have quantified the land loss at 38 square km in since 1973. But no study to date has reported the details of spatiotemporal patterns of land loss along the Sundarbans coastline, or their drivers. Under global climate change and the related sea level rise, proper understanding of how the coastlines are changing and the drivers of those changes would be essential to mitigate the impacts on the coastal mangrove forests. In this study we used a time series of Landsat MSS and TM images from 1973 to 2010 to systematically explore the spatiotemporal distributions and trends of land loss along the Sundarbans coastline of Bangladesh and India. We also used data from a host of published studies on Bay of Bengal surface currents, cyclone tracks, sea level rise, monsoonal rainfalls, sediment flow, land subsidence and anthropogenic factors to deduct probable cause-effect relationships of the trends in coastal land loss. Finally we estimated the carbon loss of the mangrove forests due to the shoreline retreat, and using IPCC scenarios we predicted the future carbon implications of these mangrove ecosystems under global climate change.
ABSTRACT: BACKGROUND: Knowledge about the relation between user involvement in the provision of assistive technology and outcomes of assistive technology use is a prerequisite for the development of efficient service delivery strategies. However, current knowledge is limited, particularly from low-income countries where affordability is an issue. The objective was therefore to explore the relation between outcomes of assistive technology use and user involvement in the service delivery process in Bangladesh. METHODS: Using structured interviews, data from 136 users of hearing aids and 149 users of manual wheelchairs were collected. Outcomes were measured using the International Outcome Inventory for Hearing Aids (IOI-HA), which was adapted for wheelchair users. Predictors of user involvement included preference, measurement and training. RESULTS: Users reported outcomes comparable to those found in other high- and low-income countries. User involvement increased the likelihood for reporting better outcomes except for measurement among hearing aid users. CONCLUSIONS: The findings support the provision of assistive technology as a strategy to improve the participation of people with disabilities in society. They also support current policies and guidelines for user-involvement in the service delivery process. Simplified strategies for provision of hearing aids may be explored. PMID:22995203
Movement is an integral part of human existence. While talking about transborder migration from Bangladesh to India, we are, however, aware that this is a controversial subject. The partition of Bengal in 1947 was the cruelest partition in the history of the world and caused forced illegal migration from erstwhile East Pakistan. It is estimated that there are about 15 million Bangladeshi nationals living in India illegally. West Bengal has a border running 2,216 km along Bangladesh. The present study highlights push-pull factors of illegal Bangladeshi migration based on perceptions of respondents obtained from a qualitative survey done on the basis of purposive sampling in Kolkata and 24 parganas and two districts of West Bengal (WB), an Indian State. The economic push factors that motivate people to leave Bangladesh are instability and economic depression, poverty, lack of employment opportunity, struggle for livelihood, forced grabbing of landed property from minority group, and lack of industrialization in Bangladesh. About 56% of the respondents expressed that lack of industrialisation/lack of employment/economic insecurity would be the probable cause of this migration. Among the demographic factors, population explosion in Bangladesh and lowest human development index may be the most important cause of illegal migration from Bangladesh to West Bengal. Hindu minority group faced problems in connection with matrimonial alliances. Educational curricula, which were framed according to Islamic preaching and curtailment of facilities enjoyed by Hindu minority group, were responsible factor for illegal migration of Hindu minority population. Another cause is social insecurity. Political instability, fear of riots and terrorism in Bangladesh, inhuman attitude and activities of the political leaders, absence of democratic rights, Muslim domination, religious instigation by political leaders, insecurity feeling of Hindus, are the major crucial issues that require to be mentioned as political push factors. About 59% of the respondents are of the opinion that religious fundamentalists/insecurity of the minority group/discriminating law and order against Hindus may be the factors that motivated migration from Bangladesh to West Bengal. In terms of "ethnic cleansing", one can witness elimination of groups of minorities by dominant ethnic group, curbing their rights controlling their influence in a state's system. Double standards are observed in punishing criminals. Police officials do not record complaints from minority community. According to 85% of the respondent economic opportunity in terms of job opportunity, economic security prevailing in West Bengal worked as pull factors for migrants to West Bengal. Geographic proximity of Bangladesh and West Bengal, the linguistics and cultural similarities, same food habit, homo-ethnic climate, belief of getting shelter, cordiality, fellow-feeling, acceptance power of people of West Bengal have contributed to the movements of population from Bangladesh to West Bengal.

The 3 forms of Colocasia fallax Schott. complex, namely green petiole form, light purple petiole form and deep purple petiole form, available in Bangladesh were studied cytogenetically to confirm their taxonomic status after staining with orcein and CMA. The green petiole form and the deep purple petiole form were found to possess 2n=28 chromosomes whereas 2n=30 chromosomes were observed in the light purple petiole form. The centromeric formula was determined as 20 m+8 sm in the green petiole form, 26 m+2 sm+2 ac in the light purple petiole form and 24 m+4 sm in the deep purple petiole form. Acrocentric chromosomes were found only in the light purple petiole form. 4 satellites were found in the green petiole form after orcein staining while only 1 satellite observed in CMA staining of the same form. These satellites showed stain specific nature in this form. 8 and 11 CMA positive bands were found in the green petiole form and the deep purple petiole form, respectively. Only 2 centromeric CMA positive bands were found in the light purple petiole form. Different CMA banding pattern and percentage of GC-rich repeats were found in these 3 forms. CMA banding was able to identify some chromosomes in the green petiole form and the deep purple petiole form. The diploid chromosome numbers and overall karyotypic features indicated that the light purple petiole form possessed quite different genomes than the other 2 forms and thus may be placed in a different taxonomic rank. Except a minute difference in the karyotypic features, the green petiole form and the deep purple petiole form possessed almost entirely similar genomes and therefore could be considered as different varieties of Colocasia fallax.
Background Breast and Cervical cancer are the two most common cancers among women in developing countries. Regular screening is the most effective way of ensuring that these cancers are detected at early stages; however few studies have assessed factors that predict cancer screening in developing countries. Purpose To assess the influence of household socio-economic status (SES), healthcare access and country level characteristics on breast and cervical cancer screening among women in developing countries. Methods Women ages 18–69 years (cervical cancer screening) and 40–69 years (breast cancer screening) from 15 developing countries who participated in the 2003 World Health Survey provided data for this study. Household SES and healthcare access was assessed based on self-reported survey responses. SAS survey procedures (SAS, Version 9.2) were used to assess determinants of breast and cervical cancer screening in separate models. Results 4.1% of women ages 18–69 years had received cervical cancer screening in the past three years, while only 2.2% of women ages 40–69 years had received breast cancer screening in the past 5 years in developing countries. Cancer screening rates varied by country; cervical cancer screening ranged from 1.1% in Bangladesh to 57.6% in Congo and breast cancer screening ranged from 0% in Mali to 26% in Congo. Significant determinants of cancer screening were household SES, rural residence, country health expenditure (as a percent of GDP) as well as healthcare access. Discussion A lot more needs to be done to improve screening rates for breast and cervical cancer in developing countries, such as increasing health expenditure (especially in rural areas), applying the increased funds towards the provision of more, better educated health providers as well as improved infrastructure.

The Asia-Pacific Programme of Education for All (APPEAL), UNESCO, is a cooperative program designed to promote education for all in the region. Its principal aim is to promote primary education, literacy, and continuing education for all and particularly for disadvantaged groups. APPEAL/PROAP has instituted the project, Promotion of Basic Education and Lifelong Learning for Gender Equality through CLCs, to improve and strengthen basic education and lifelong learning for gender equality. The project will build upon the expertise and experience of community learning centers (CLCs), which have been providing non-formal education for over 3 years, with girls and women one of their target groups. CLCs provide a supportive atmosphere for learning and have helped improve the status of girls and women in their communities. Objectives of the technical workshop held in Indonesia in March 2001 were to: review the situation in the region regarding basic education and lifelong learning for gender equality; develop a framework for undertaking a pilot study on innovative strategies for basic education and lifelong learning for gender equality through CLCs in the region; and formulate an action plan for undertaking research. Attending the workshop were 23 participants from 13 countries implementing learning centers projects supported by UNESCO APPEAL and 11 observers from Indonesia. The 13 countries are Bangladesh, Cambodia, China, India, Indonesia, Lao PDR, Malaysia, Mongolia, Nepal, Pakistan, Philippines, Thailand, and Viet Nam. Work groups participated in: presentations on concepts and requirements related to basic education, lifelong learning, and gender equality, and guidelines for sharing; undertook a field visit; and discussed how to carry out their research and reach their objectives. Annexes to this final report contain a schedule of work, list of participants, opening remarks, sharing country experience works groups, and guidelines for group discussion. (BT)
Two species of the genus Solanum viz. S. nigrum and S. villosum found in Bangladesh were cytogenetically investigated to confirm their taxonomic status. S. nigrum and S. villosum were found to possess 2n=24 and 2n=48 chromosomes, respectively. The centromeric formula 22m+2sm was found in S. nigrum and 48m in S. villosum. No gradual decrease of chromosomal length was observed in both the species indicated their karyotypes as primitive type. The individual chromosomal length ranged from 1.66 to 2.34 ?m in S. nigrum and 1.66 to 2.66 ?m in S. villosum. The total chromatin length in S. villosum (97.8 ?m) was almost double to that of S. nigrum (48.94 ?m). The range of relative length of chromosomes was similar in these two species. Solanum nigrum and S. villosum possessed 18 and 17 CMA positive bands, respectively. Most of the CMA-bands were present at the terminal region in both the species. The percentage of CMA banded region in S. villosum (35.43) was almost double to that of S. nigrum (18.69). A pair of DAPI positive bands was found on both the end of all the chromosomes in these 2 species. Each band was 0.5 ?m in length. The karyotype of S. nigrum studied here indicated that the specimen was not actually S. nigrum rather it has much simillarities with S. americanum. Solanum villosum showed regular bivalent formation at metaphase-I and segregation at anaphase-I. The overall karyotypic features suggested S. villosum as an ancient auto-tetraploid of S. americanum which in course of time has started regular meiosis.
Millions of people in Bangladesh and West Bengal, India are drinking groundwater from Bengal Basin aquifers with unsafe levels of arsenic. A promising mitigation option is development of deep groundwater in areas where water quality at depth is high. Deep groundwater is already in use in many areas, but proper management is necessary to maintain a safe water supply for this and future generations. Pumping at depth may induce downward migration of arsenic from shallow, contaminated aquifer zones in areas where physical (groundwater flowpaths) and chemical (arsenic sorption or reaction) protection does not occur or is insufficient. Understanding these protection mechanisms and conditions in which they are undermined is critical to determining the sustainability of mitigation options. We use a basin-scale groundwater flow and solute transport model considering advective flowpaths and dispersive solute transport with sorption to investigate the sustainability of deep groundwater pumping options within the high-arsenic area of the Bengal Basin. On a large scale, distributed pumping for both domestic and irrigation use is considered, including future scenarios in which domestic use increases due to population growth or piped supply. Regional modeling indicates that limited pumping at depth (current domestic supply and future supply under sorbing conditions) is critical to sustainability of the deep groundwater resource. However, basin-scale modeling does not consider effects of point pumping from community or municipal wells, as may be installed for this mitigation option, or local geologic conditions. Small-scale models are developed to consider these effects, and recommendations for the future are made.
A five-year Coordinated Research Project (CRP) entitled 'Integrated approach for improving small scale market oriented dairy systems' is currently being implemented by the Food and Agriculture Organization and the International Atomic Energy Agency, through their Joint Programme on 'Nuclear Techniques in Food and Agriculture'. The objectives are to (a) identify and prioritize the constraints and opportunities in the selected dairy farms; (b) determine the most important limiting factors; (c) develop intervention strategies; (c) assess the economic impact of the interventions; (d) develop methodologies for recording and demonstrating the economic impact; and (e) promote the adoption and dissemination of proven strategies and methodologies. Fifteen institutes in developing as well as developed countries are participating in the project, through ten research contracts (Bangladesh, Cameroon, Pakistan, Paraguay, Peru, South Africa, Sri Lanka, Tanzania, Tunisia and Venezuela), one technical contract (Peru) and four research agreements (Malaysia, U.K., U.S.A. and Uruguay). The initial phase of the project, which focused on the conduct of Participatory Rural Appraisals and Economic Opportunity Surveys in the countries of the research contract holders, has now been completed. This paper describes the background to the CRP approach and the procedures used for developing, initiating and implementing this project. PMID:18265863
This study assessed the quality of care provided by community health workers (CHWs) in managing cases of severe acute malnutrition (SAM) according to a treatment algorithm. A mixed methods approach was employed to provide perspectives on different aspects of quality of care, including technical competence and acceptability to caretakers. CHWs screened children at community level using a mid-upper arm circumference measurement, and treated cases without medical complications. Fifty-five case management observations were conducted using a quality of care checklist, with 89.1% (95% confidence interval: 77.8-95.9%) of CHWs achieving 90% error-free case management or higher. Caretakers perceived CHWs' services as acceptable and valuable, with doorstep delivery of services promoting early presentation in this remote area of Bangladesh. Integration of the treatment of SAM into community-based health and nutrition programs appears to be feasible and effective. In this setting, well-trained and supervised CHWs were able to effectively manage cases of SAM. These findings suggest the feasibility of further decentralization of treatment from current delivery models for community-based management of acute malnutrition. PMID:22515318
This article seeks to draw possible lessons for adaptation programmes in Bangladesh by examining whether cyclone preparedness and relief interventions are subject to corrupt practices. Based on a random sample survey of 278 households, three focus-group discussions and seven key-informant interviews, the article investigates the nature and extent of corruption in pre- and post-disaster interventions in Khulna before and after Cyclone Aila in May 2009. Ninety nine percent of households reported losses from corrupt practices. Post-disaster interventions (such as food aid and public works schemes) suffered from greater levels, and worse types, of corruption than pre-disaster interventions (such as cyclone warning systems and disaster-preparedness training). Using an asset index created using principal component analysis, the article assesses how corruption affected wealth quartiles. Ultra-poor households were affected more by corruption in pre-disaster interventions, the wealthiest quartile more in certain post-disaster interventions, in particular public works and non-governmental interventions. These findings may hold lessons for attempts to increase resilience as current adaptation measures mirror some cyclone preparedness and relief efforts.
Growth and mortality parameters, exploitation rates, annual recruitment patterns and length-weight relationships were estimated from monthly length-frequency and weight samples of Ilisha filigera, captured mainly by set bag nets (SBNs), from the upper Bay of Bengal off the Bangladesh coast using the FiSAT program. The objective of this study is to estimate growth parameters, mortality rates, and the exploitation rate and recruitment pattern of I. filigera for sustainable management. The von Bertalanffy growth parameters, asymptotic length L8 (cm) and growth constant K (per year), were found to be 48.90 and 0.80, respectively. The L8 and Z/K estimates provided by the Wetherall plot were 48.487 cm and 2.517. The annual rate of fishing mortality (F = 0.91) was low compared to the relatively high natural mortality (M = 1.35). The value of the exploitation rate (E = 0.40) suggested that the species was not over-exploited by SBNs operation in the region. About 53.33% of I. filigera were found to be recruited during the August-October period, and 46.67% during the March-May period. The growth performance index (?') was 3.28. The total length and body weight relationship was found to be W = 0.0318 L2.5803 suggesting that the growth rate displayed a negative allometric pattern (b < 3). The growth parameters derived in the current study were found to be comparable with previous estimates available for the same species from the Bay of Bengal and from other localities.

The reduction of Fe (III) to Fe (II) and of arsenate (As (V)) to arsenite (As (III)) by Fe (III) reducing and As (V) respiring prokaryotes such as the bacterium Shewanella sp. ANA-3 may contribute to arsenic mobilization in aquifers contaminated with arsenic, specifically in places such as Bangladesh. Under oxic conditions As (V) predominates and is often adsorbed onto mineral surfaces such as amorphous ferrihydrite. However, under anoxic conditions As (III) predominates, sorbs to fewer minerals, and has a greater hydrologic mobility compared to As (V). The genetic mechanism underlying arsenic release from subsurface material most likely involves a combination of respiratory gene clusters (e.g. mtr/omc and arr). In this study, we are investigating the genetic pathways underlying arsenic mobilization. We have generated various mutations in the mtr/omc gene cluster, which encodes several outermembrane decaheme c-type cytochromes. Deletions in one mtr/omc gene did not eliminate iron reduction. However, strains carrying multiple gene deletions were greatly impaired in iron reduction abilities. Work is currently underway to generate combinations of iron reduction and arsenate reduction single and double mutants that will be used to investigate microbial mobilization of arsenic in flow-through columns containing As (V)-HFO coated sand. This work will address the importance of arsenate reduction and iron reduction in the mobilization of arsenic.
Arsenic is a highly toxic element and its presence in food composites is a matter of concern to the well being of both humans and animals. Arsenic-contaminated groundwater is often used in Bangladesh and West Bengal (India) to irrigate crops used for food and animal consumption, which could potentially lead to arsenic entering the human food chain. In this study, we used graphite furnace atomic absorption spectroscopy to determine the total arsenic concentrations in a range of foodstuffs, including vegetables, rice and fish, imported into the United Kingdom from Bangladesh. The mean and range of the total arsenic concentration in all the vegetables imported from Bangladesh were 54.5 and 5-540 {mu}g/kg, respectively. The highest arsenic values found were for the skin of Arum tuber, 540 {mu}g/kg, followed by Arum Stem, 168 {mu}g/kg, and Amaranthus, 160 {mu}g/kg. Among the other samples, freshwater fish contained total arsenic levels between 97 and 1318 {mu}g/kg. The arsenic content of the vegetables from the UK was approximately 2- to 3-fold lower than those observed for the vegetables imported from Bangladesh. The levels of arsenic found in vegetables imported from Bangladesh in this study, in some cases, are similar to those previously recorded for vegetables grown in arsenic-affected areas of West Bengal, India, although lower than the levels reported in studies from Bangladesh. While the total arsenic content detected in our study in vegetables, imported from Bangladesh, is far less than the recommended maximum permitted level of arsenic, it does provide an additional source of arsenic in the diet. This raises the possibility that the level of arsenic intake by certain sectors of the UK population may be significantly higher then the general population and requires further investigations.

The Water Framework Directive (WFD) is an ambitious piece of legislation focused on achieving good ecological status as defined by deviations from reference conditions. Achieving good ecological status depends on collaboration between stakeholders, scientists and the public. However, public participation is restricted to consultations about implementing measures to achieve good ecological status, not in the goal setting. There are multiple, competing interpretations of good ecological status. This study addresses two of the pillars of the WFD, good ecological status and public participation. We argue that these two pillars are currently at odds when defining reference conditions for surface waters, and it is unclear how they can work together in practice. We also contend that there is an i...

The Marine Strategy Framework Directive (MSFD) aims to achieve Good Environmental Status (GES) in Europe's Seas. The requirement for regional sea authorities to identify and prioritise issues for management has meant that standardized methods to assess the current level of departure from GES are needed. The methodology presented here provides a means by which existing information describing the status of ecosystem components of a regional sea can be used to determine the effort required to achieve GES. A risk assessment framework was developed to score departure from GES for 10 out of the 11 GES descriptors, based on proposed definitions of 'good' status, and current knowledge of environmental status in each of the four regional seas (North-East Atlantic, Mediterranean Sea, Baltic Sea and ...
OPINION STATEMENT: Status epilepticus is characterized by a prolonged, self-sustaining seizure or repeated seizures without return to baseline. The clinical manifestations of status epilepticus in children and adults range from overt generalized convulsions to more subtle behavioral manifestations, including unresponsiveness in the setting of the intensive care unit. Status epilepticus is the most common neurologic emergency of childhood. A large proportion of these episodes are the result of a prolonged febrile seizure or an acute symptomatic etiology. Fortunately, status epilepticus occurs without consequence for many children, but for others, it is correlated with long-term neurologic dysfunction or death. Treatment of status epilepticus should commence promptly upon its recognition, using predefined treatment protocols. The goal of treatment is the rapid termination of the seizure, to minimize the acute and chronic effects of this emergency and to allow for the prompt assessment and management of the underlying precipitant. Currently, the drug class of first choice in the in-hospital and out-of-hospital treatment of status epilepticus is the benzodiazepines, which may need to be quickly followed by a next-line agent, as the efficacy of the benzodiazepines is negatively correlated with seizure duration. Traditionally, these next-line agents have included phenobarbital and phenytoin, but emerging evidence supports the use of intravenous formulations of other antiepileptic drugs. If the first two agents fail, high-dose intravenous midazolam or anesthetic therapy should be rapidly initiated. This paper reviews the current treatment options and strategies for pediatric patients with status epilepticus. PMID:21956209

One of the greatest challenges facing theoretical physics lies in reconciling Einstein`s classical theory of gravity - general relativity -with quantum field theory. Although both theories have been experimentally supported in their respective regimes, they are as compatible as a square peg and a round hole. This article summarises the currentstatus of the superstring approach to the problem, the status of the Ashtekar program, and problem of time in quantum gravity.
Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.
In line with evolutionary principles of reproduction and mate selection, the current research shows that women's attention to status cues fluctuates across their menstrual cycle. Specifically, we show that women pay more attention to status products in a visual display around ovulation than in other phases of their menstrual cycle. Pill use eliminates these cycle phase effects. The results are discussed in relation to research on female mating goals and conspicuous consumption.

The report describes the facility maintenance and environmental work completed, status of completing technical reports and certain key administrative actions occurring during the quarter. In view of current year budget reductions and program reductions to closeout the MHD program, downsizing of the UTSI work force took place. No further testing occurred or was scheduled during the quarter, but the DOE CFFF facility was maintained in a standby status.
Using choice experiment data for economic valuation we analyse how disbelief in survey information could affect the retrieved welfare estimates. We distinguish between two types of survey information to the respondents. The first type of information concerns the current environmental status of a water body. This information is provided prior to the valuation questions and the corresponding beliefs in the provided information are also elicited before valuation. The second type of information concerns the proposed improvements in the environmental status of the water body. We find that average welfare measures differ considerably according to whether respondents who disagree with the status quo levels and find proposed scenarios unlikely are included or not.
Breast cancer is the most common malignancy amongst women in the developed world. For patients with hormone-sensitive breast cancer eligible for adjuvant hormonal therapy, it is important to know if the ovaries are (still) functional or not. Indeed, the choice for a specific adjuvant hormonal treatment depends on the menopausal status of an individual woman. The currently available measures to determine the menopausal status are conflicting. Until better measures become available, we propose a practical guideline enabling an optimal choice of adjuvant hormonal therapy for women with a hormone receptor positive breast cancer taking into account uncertainties about their menopausal status.

Effective tools for monitoring the status of ecological restoration projects are critical for the management of restoration programs. Such tools must integrate disparate data comprised of multiple variables that describe restoration status, including the condition of environmental stressors, landscape connectivity, ecosystem resilience, and ecological structure and function, while communicating these concepts effectively to a wide range of stakeholders. In this paper we describe the process of constructing multimetric indices (MMIs) for monitoring restoration status for restoration projects currently underway on the eastern coast of Saudi Arabia. During this process, an initial suite of measurements is filtered for response and sensitivity to ecosystem stressors, eliminating measurements t...

Although transboundary river flow accounts for more than 40% of global surface flow across 145 nations (many of them water-stressed and conflict-prone), most of this flow is difficult to monitor in developing nations at operational timescales. For Bangladesh, this situation is particularly acute because it comprises only 7% of the entire Ganges-Brahmaputra-Meghna basin and is located at the downstream end of the basin. Thus more than 90% of the water is generated in upstream nations and yet this information is hard to obtain in Bangladesh due to lack of transboundary instrumentation or international treaties. This work therefore investigates the value of satellite radar altimetry in detecting the water level changes for large rivers in the Bangladesh Delta. It is founded on the hypothesis that a satellite altimeter can detect water level to the same accuracy for both inside and outside of Bangladesh. First, the river hydraulic model called HEC-RAS (Hydrologic Engineering Center, River Analysis System) is set up and calibrated over Bangladesh using a comprehensive database on in-situ river bathymetry and observed water level records. Next, the calibrated HEC-RAS model is provided boundary flow conditions upstream and downstream of the model domain. At the upstream end where the Ganges, Brahmaputra and Meghan enter Bangladesh, high resolution flow data modeled from a well calibrated hydrologic model called MIKE BASIN is provided as input. The observed tidal flow records of the Meghna estuary near the Bay of Bengal are used as the downstream boundary conditions. HEC-RAS is then used to simulate daily water level data for the period of 2003-2005 for major rivers of Bangladesh. These water level simulations are directly compared with altimeter estimates of water level from the ENVISAT mission. Accuracy of ENVISAT data is characterized as a function of season, flow regime and river type. The important question that this study aims to answer is, “To what extent can Surface Water Ocean Topography (SWOT) mission capture the water level dynamics of large rivers in Bangladesh Delta?” Location of matched Envisat intersections over Bangladesh with model river network (water stage data of these locations are available for the period of 2003-05)
Diurnal temperature range (DTR) is a meteorological indicator independent of internal climate variation and therefore, considered as a signature of observed climate change. It has been observed that global averaged DTR has decreased significantly in the last fifty years. However, the change in DTR has regional and seasonal characteristics. A study has been carried out in this paper to analyze the spatial and seasonal patterns in the trends of DTR in Bangladesh. Daily temperature data from 18 stations for the time period 1961–2008 has been used for the study. The result shows that both mean minimum and mean maximum temperatures of Bangladesh have increased significantly at a rate of 0.15 °C/decade and 0.11 °C/decade, respectively. However, the increase of minimum temperature compared to maximum temperature is not high enough to cause a significant change in average diurnal temperature range in Bangladesh. Seasonal DTR trends show a decrease in winter and pre-monsoon DTR, and an increase in monsoon DTR. Spatial distribution of DTR trends shows an increase of annual DTR in the southeastern coastal stations and decrease in the northern stations of Bangladesh. Significant negative relation between rainfall and DTR is observed in Bangladesh. Regression analysis shows that an annual increase of 1% of rainfall is correlated with a decrease of DTR by 0.1 °C.
Bangladesh is richly endowed with solar energy. Solar Photovoltaic (PV) system seems to be an appropriate form of renewable energy despite the monsoon type of climate in Bangladesh. The most attractive use of solar home system (SHS) in Bangladesh is the lighting system. People in rural Bangladesh predominantly use kerosene oil based lamps for illuminating their homes at night. Dry cell batteries are used for radio and gradually car batteries are becoming popular for running TV near grid areas where the charging facilities are available. The cost of kerosene and charging cost of battery are quite high and solar home system can compete with them in this particular field. Six cases were analyzed to find out the economic sustainability of the solar home systems at selected villages in Gazipur district, Bangladesh during October 2004-December 2004 and also questionnaire survey method was followed to collect data. This study reveals that the solar home system is financially attractive for small rural business and household lighting with entertainment. Only for household lighting purpose the system is not financially and economically viable without considering social benefits. (author)
The current qualitative study of 35 preadoptive gay male couples (70 men) examined gay men's motivations to parent and their reasons for pursuing parenthood at the current time. Similar to heterosexual couples, gay men described a range of psychologically oriented reasons as shaping their decision to become parents. Some of these (e.g., desire to teach a child tolerance) may have been uniquely shaped by their sexual minority status, and others (e.g., desire to give a child a good home) in part reflect their adoptive status. Men named age, finances, and relationship factors, as well as unique contextual factors such as the need to find and move to gay-friendly neighborhoods, as influencing their readiness to pursue parenthood at the current time. Gay men's motivations to parent echo normative life course decision-making processes, but also reflect concerns that are uniquely informed by their sexual minority status.
Two separate field experiments were carried out in two different agro-ecological zones in Bangladesh. The experimental sites selected were the Bangladesh Agricultural University (BAU) farm in Mymensingh and a farmers' field in Madhupur. The objective was to investigate the response of super granules of urea (USG), Urea-DAP and NPK on HYV rice crops. Soil types under investigation at both the BAU farm site and at the Madhupur farmers' field were silt-loam in texture and poor in nutrient status. The soil reaction was mildly acidic (pH 6.8) at the BAU farm, while it was strongly acidic at the Madhupur farmers' field (pH 5.5). Fertilizer treatments used in the experiments were (1) Control (without any fertilizer), (2) Urea (70 kg N ha-1 from urea), (3) USG (52 kg N ha-1 from USG super granule), (4) Urea-DAP SG (52 kg N and 20 kg P2O5 ha-1 from Urea-DAP super granule) and (5) NPK SG (52 kg N, 20 kg P2O5 and 20 kg K2O ha-1 from NPK super granule). In treatments 2-3, P, K, S and Zn fertilizers were applied as basal @ 40 kg P2O5, 40 kg K2O, 20 kg S and 3 kg Zn ha-1 respectively. In treatment 4, K was applied as basal @ 40 kg K2O ha-1 along with S and Zn as in treatments 2-3, while in the case of treatment 5, S and Zn were applied as basal as in treatments 2-3. USG, Urea-DAP, and NPK super granules were point placed after 7 days of transplanting at a depth of 7 centimeter between every fourth rice mound. Each treatment was replicated four times in a completely randomized block design. Test crops used were HYV rice, BR-30 at the BAU farm and BR-11 at the Madhupur farmers' field. The experiments were conducted during the wet season (July-November) of 2001. Point placement of USG, Urea-DAP and NPK super granules greatly increased the grain yields of rice. The highest increase in grain yield was recorded in NPK super granule followed by Urea-DAP and USG point placemen at both of the experiment site. The maximum grain yield at the BAU farm recorded was 6.23 t ha-1, while at the Madhupur farmers' field it was 5.73 t ha-1 using the NPK super granule point placement. The minimum yields of rice grain were obtained in the control treatment at both the BAU (3.41 t ha-1) and Madhupur farmers' field (3.22 t ha-1). Point placement of USG and multi-nutrient fertilizers in super granules both NP and NPK appeared to be highly promising for application on wetland rice.
Purpose The authors review their experiences during multiple cleft surgical missions to rural Bangladesh from 2006 to 2008. A significant number of patients who underwent primary palatoplasty or cheiloplasty were of adult age or size. Adult primary cleft lip and palate repair is often more challenging than repair at the standard age of fewer than 2 years. This patient population is rarely seen in the United States, but may be treated more often by American surgeons during surgical missions to the developing world. This report discusses the experiences of the authors' treatment of cleft lips and palates in rural Bangladesh. Patients and Methods One hundred forty-six cleft-lip and cleft-palate patients were treated during 3 missions to rural Bangladesh, from 2006 to 2008. Thirty-three (23%) ...
This article explores the drivers, benefits, and challenges to climate change adaptation in Bangladesh. It specifically investigates the ?Community Based Adaptation to Climate Change through Coastal Afforestation Program,? a 5-year $5 million adaptation scheme being funded and implemented in part by the Government of Bangladesh, United Nations Development Program, and Global Environment Facility. The article explores how the CBACC-CA builds various types of adaptive capacity in Bangladesh and the extent its design and implementation offers lessons for other adaptation programs around the world. The first part of the study begins by describing its research methods consisting of research interviews, site visits, and a literature review. It then summarizes six primary sectors vulnerable to cl...
Meteorological drought events occur in Bangladesh are diagnosed using monthly rainfall and mean air temperature from the surface observations and Regional Climate Model (RegCM) by calculating Standardized Precipitation Index (SPI) and Palmer Drought Severity Index (PDSI) for the period 1961?1990. The historical records of drought event obtained from the Bangladesh Bureau of Statistics and International Disaster Database are used to verify the SPI and PDSI detected events. The SPI and monthly PDSI are obtained for 27 station data across Bangladesh as well as for two subregions over the country. Result based on the observed data shows that regional information is better in drought diagnosis compared to the point information. The regional analysis is able to detect about 80?% of the drought e...
Summary Since the first outbreak of highly pathogenic H5N1 avian inafluenza (HPAI) in Bangladesh in February 2007, a total of 519 disease events have been reported till 22 October 2011. Partial HA gene sequences of 11 selected H5N1 HPAI isolates of 2007 to 2011 were determined and subjected to phylogenetic analysis. The study revealed a recent introduction of clade 2.3.2 and 2.3.4 viruses into Bangladesh in 2011 in addition to clade 2.2 viruses that had been in circulation since 2007. Clade 2.3.2 virus isolates from Bangladesh are phylogenetically related to the newly designated clade 2.3.2.1 viruses, reported recently from Asia and Eastern Europe.

Quantitative evaluations of the impact of groundwater abstraction on recharge are rare. Over a period (1975???2007) during which groundwater abstraction increased dramatically in the Bengal Basin, changes in net groundwater recharge in Bangladesh are assessed using the water-table fluctuation method. Mean annual groundwater recharge is shown to be higher (300???600 mm) in northwestern and southwestern areas of Bangladesh than in southeastern and northeastern regions (<100 mm) where rainfall and potential recharge are greater. Net recharge in many parts of Bangladesh has increased substantially (5???15 mm/year between 1985 and 2007) in response to increased groundwater abstraction for irrigation and urban water supplies. In contrast, net recharge has slightly decreased (???0.5 to ???1 m...
The supply of petroleum and its products plays a very important role in the whole national economy and for political stability of Bangladesh because almost all consumption sectors depend exclusively on hydrocarbon supplies. Until now 8 gas fields with exploitable reserves of 230 billion m/sup 3/ were discovered, whereas petroleum was found only in non commercial amounts. Four producing gas fields have an annual output of 0,6 billion m/sup 3/. Bangladesh gas is high graded, almost sulphur free, dry and contains about 94-99% of methane. The reservoir rocks of the gas fields have porosities ranging between 17-33% and the gas saturation percentage reaches till 80%. A possible petroliferous character of Bengal-Basin is still a topic under discussion. Many geochemical analyses indicate Bangladesh as a pure gas province.
A field experiment was conducted at the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh to study the effectiveness of Bradyrhizobium japonicum strains on two varieties of soybean viz. Sohag and Bangladesh Soybean-4. The treatments were non inoculated control, seed inoculation with either Bradyrhizobium japonucum strains TAL102, TAL1906 or the mixed culture of strains TAL102 and TAL1906, Nitrogen amount of 25 or 50 kg/ha. Bradyrhizobium inoculation had a significant positive effect on nodulation, nitrogenase activity, growth, dry matter production, N content in shoot, N uptake by shoot, yield attributes, protein content in seed and seed and stover yields of soybean. The highest seed yield of 2511 kg/ha was obtained in Bangladesh Soybean-4 inoculated with Bradyrhizobium japonicum strain TAL102. Treatments consisting of chemical nitrogen fertilizer did not perform well compared to those employing the Bradyrhizobium inoculant.
Although burn disaster is not a frequent event, with urbanisation and industrialisation, burn disaster is becoming an emerging problem in Bangladesh. On 3 June 2010, a fire disaster killed 124 people in Neemtali, Dhaka, Bangladesh. This paper narrates the management of burn patients of this disaster in the burn unit of Dhaka Medical College Hospital. The burn unit managed 192 burn victims of the disaster. Forty-two victims were admitted and 150 of them received primary care at the emergency room and were sent back home. Ten patients among 42 in-patients died. The in-patient mortality was 23.8%. Burn unit in Dhaka Medical College Hospital is the only burn management centre in Bangladesh. Proper planning and coordinated effort by all sectors and persons concerned were the key elements in this successful management. PMID:21321648
Kutubdia is an island in the southern coast of Bangladesh where mainland grid electricity is not present or would not feasible in near future. Presently, electricity is generated using a diesel generator by Bangladesh Power Development Board (BPDB) for a limited time and location. Due to its remote location, the fuel cost in Kutubdia is very expensive. In the present study one-year recorded wind by Bangladesh Centre of Advanced Studies (BCAS) location and other three potential locations for hybrid system analysis is discussed. The system configuration of the hybrid is achieved based on a theoretical domestic load at the island. The sizing of the hybrid power systems is discussed with 0% and 5% annual capacity of shortage. This feasibility study indicates that wind–PV–diesel...
Geographically, Bangladesh is considered to be one of the most cyclone-prone areas in the world. The super cyclone Sidr in 2007 was one of the most devastating disasters to have ever occurred in Bangladesh, having wind speeds of 223 km/h with a tidal surge of 6.1?7.6 m high. In order to draw a pre- and post-Sidr damage and management scenario, a survey was conducted at Dumki upazila, Patuakhali district in Bangladesh with a pretested questionnaire. Primary data were collected through a questionnaire, while secondary data were collected from pertinent offices as well as academic journals. The major focus of this study was to assess the state of pre-Sidr tree plantations (woody and fruit trees), the devastation caused by Sidr on these tree plantations, and post-Sidr recovery and further sust...
Although Phlebotomus argentipes as the only known vector of visceral leishmaniasis (VL) is zoophilic in nature, VL is considered to be anthroponotic in the Indian subcontinent. Peripheral blood samples from 85 stray dogs were examined for any molecular evidence of Leishmania infection in VL endemic areas of Bangladesh. Parasite DNA was detected in a blood sample from 1 of 85 (1.2%) stray dogs using ITS1-PCR, and PCR sequencing of the rRNA-ITS and cytochrome b gene confirmed that the parasitic DNA was Leishmania donovani. The results support the assumption that dogs are a probable animal reservoir for the Leishmania parasite in Bangladesh. It will be important to investigate the possible epidemiological role of dogs in domestic foci of VL endemic areas in Bangladesh.
Rapid growth in the demand for commercial energy in Bangladesh poses serious development constraints in recent years. Per capita energy consumption of Bangladesh is one of the lowest in the world (252 kgoe in 2005). This paper undertakes an empirical investigation to find out the trends in energy intensities by comparing the energy consumption per capita and energy consumption per GDP for agriculture, industry, commercial, and transport sectors of Bangladesh and investigate their conditions over the long run. Only 43% of total population has access to electricity facility. Though natural gas provides two-third of the nation?s commercial fossil fuel supply, only 4% households have access to natural gas networks. Biomass fuels are estimated to account for about 73% of the country?s primary e...
Bangladesh is an energy starving country. The country will be on one of the fast growing power markets with its population and growing energy demand per person, its fast growing urbanization, and its socio-economic development. At present the potential demand of power is 5569MW and the supply is below 4000MW. The country is dependent on the imported petroleum that is big burden on the economy. The per capita emission is only 0.2667tonneperperson still much below the world leading countries (19.8tonneperperson for USA). However, Bangladesh is one of the most vulnerable to climate change effect in the world. In this regard, renewable energy resources appear to be the one of the most efficient and effective solution for clean and sustainable energy development in Bangladesh. Biomass is the do...
Abstract Objective- To examine the space-time clustering of dengue fever (DF) transmission in Bangladesh using geographical information system and spatial scan statistics (SaTScan). Methods- We obtained data on monthly suspected DF cases and deaths by district in Bangladesh for the period of 2000-2009 from Directorate General of Health Services. Population and district boundary data of each district were collected from national census managed by Bangladesh Bureau of Statistics. To identify the space-time clusters of DF transmission a discrete Poisson model was performed using SaTScan software. Results- Space-time distribution of DF transmission was clustered during three periods 2000-2002, 2003-2005 and 2006-2009. Dhaka was the most likely cluster for DF in all three periods. Several other...
One of the major functions of telemedicine is the prompt delivery of modern healthcare to the remotest areas with reduced cost and efficient use of communication resources. The establishment of a well organized telemedicine system is therefore exigent for the developing countries like Bangladesh where there are extreme paucities of efficient healthcare professionals and equipments, specifically in the rural areas. In this paper a novel, hierarchical and semi-centralized telemedicine network architecture has been proposed holisti-cally focusing on the rural underdeveloped areas of Bangladesh. The model utilizes the existing fiber optic backbone and wireless telecommunication infrastructures to connect the remote healthcare centers with the urban special-ized hospitals. The proposed network is of low cost, flexible and faster as well as more concrete than the existing healthcare organogram of Bangladesh. Finally, some features and services associated with the model have also been proposed which are pragmatic and easily implementable.
Korea has achieved remarkable results in the development of nuclear technology over the past years. Nuclear R and D programs have been actively pursued with the aim of enhancing nuclear technological capability to the level of nuclear advanced countries by early 2000. Worth noting is the fact that the IAEA has played an important role in facilitating Korea's acquisition of advanced nuclear technologies by participating in IAEA technical cooperation programmes, and technical cooperation with the IAEA has laid a firm groundwork for Korea to achieve self-reliance in nuclear technology. Technical cooperation with the IAEA should be steadily pursued so that Korea can play a leading role in the international nuclear arena in the years to come. Up to now, the study of major programmes and of the currentstatus of overall technical cooperation projects, which have been implemented by the IAEA, has been insufficient. It should be noted that analysis of the assistance provided by the IAEA leaves something to be desired. In this regard, analyzing the currentstatus of technical cooperation projects as well as recommending policy direction is required in a bid to implement IAEA technical cooperation projects systematically. Korea's status within the IAEA, including activities in the Advisory Committee and the currentstatus of its participation in Coordinated Research Programmes (CRP) and other major programmes underway, is presented in this report. The policy direction for and implementation status of IAEA technical cooperation programmes are explained at length. The currentstatus of technical cooperation programmes carried out in the 1997-1998 cycle and those to be implemented in the 1992-2000 cycle are also described in this report. Strategies for upgrading Korea's status within the IAEA as well as directions for nuclear cooperation through the IAEA were presented in this study to positively deal with rapid changes in the international nuclear arena and to efficiently carry out national nuclear policy.

The currentstatus of renal diagnostic nuclear medicine is explained in a concise but nevertheless comprehensive survey, explaining the advances made and comparing former and currentstatus with regard to radiopharmacy, techniques, and indications. The important advances achieved, such as gamma-camera, computerized renography, production of new radiopharmaceuticals (perfusion, parenchyma and inflammatory process markers) have induced a change in diagnostic nuclear medicine for kidney studies that requires a re-orientation among experts, and the book in hand is intended to furnish the necessary information. With 19 figs., 4 tabs.
The theoretical status of the `proton spin' effect is reviewed. The conventional QCD parton model analysis of polarised DIS is compared with a complementary approach, the composite operator propagator-vertex (CPV) method, each of which provides its own insight into the origin of the observed suppression in the first moment of $g_1^p$. The currentstatus of both experiment and non-perturbative calculations is summarised. The future role of semi-inclusive DIS experiments, in both the current and target fragmentation regions, is described.
The electrochemical reaction of glucose on a thin gold film electrode was investigated using the surface plasmon resonance (SPR) method. A cyclic voltammogram of glucose on a thin gold film electrode showed anodic current in both anodic and cathodic scans. The potential dependence of the refractive index change was simultaneously measured by SPR and showed that the change in the gold electrode surface status switched the catalytic reaction. In addition, a potential step experiment revealed that the SPR signal showed the underlying electrode status whereas the electrode current showed the overall catalytic oxidation of glucose.
The Kyoto Protocol provides for the involvement of developing countries in an atmospheric greenhouse gas reduction regime under its Clean Development Mechanism (CDM). Carbon credits are gained from reforestation and afforestation activities in developing countries. Bangladesh, a densely populated tropical country in South Asia, has a huge degraded forestland which can be reforested by CDM projects. To realize the potential of the forestry sector in developing countries for full-scale emission mitigation, the carbon sequestration potential of different species in different types of plantations should be integrated with the carbon trading system under the CDM of the Kyoto Protocol. This paper discusses the prospects and problems of carbon trading in Bangladesh, in relation to the CDM, in the context of global warming and the potential associated consequences. The paper analyzes the effects of reforestation projects on carbon sequestration in Bangladesh, in general, and in the hilly Chittagong region, in particular, and concludes by demonstrating the carbon trading opportunities. Results showed that tree tissue in the forests of Bangladesh stored 92tons of carbon per hectare (tC/ha), on average. The results also revealed a gross stock of 190tC/ha in the plantations of 13 tree species, ranging in age from 6 to 23 years. The paper confirms the huge atmospheric CO(2) offset by the forests if the degraded forestlands are reforested by CDM projects, indicating the potential of Bangladesh to participate in carbon trading for both its economic and environmental benefit. Within the forestry sector itself, some constraints are identified; nevertheless, the results of the study can expedite policy decisions regarding Bangladesh's participation in carbon trading through the CDM.

Radar data from the Bangladesh Meteorological Department (BMD) are employed as a preliminary analysis. This is a first research work to investigate the spatial and temporal distribution of rainfall over the country for 135 consecutive days, from 16 April to 30 August 2000. Radar data are sampled in 10 km grid boxes to obtain daily rainfall over the country. Rain gauge data at 33 locations are utilized to check the radar results. The distributions of rainfall obtained by both the radar and the rain gauges are similarin pattern, but the time of the maximum rainfall determined by the radar is a few hours earlier than that determined by the rain gauges. The distribution of rainfall over the whole radar domain suggests that 21 to 09 local standard time (LST) is the most likely time for rainfall to occur in Bangladesh, while 06 LST is the most likely time for maximum rainfall to occur over the entire country. It is mentioned that no data are available between 03-06 LST. The occurrence of 21 to 09 LST rainfall is possibly linked to the local effects such as complex terrain and sea and land breeze circulations. The morning maximum rainfall at 06 LST in Bangladesh is different from that of the Indian subcontinent or of the mountain area where, generally, maximum rainfall occurs in the afternoon. The northern border of Bangladesh, close to the Shillong hill of India, is the region with the highest rainfall, while the second highest volume of rainfall occurs on the eastern border. In order to observe the characteristics of large-scale cloud activity, analyses of the Japanese GMS-5 hourly infrared data, within a larger domain of 80°-100°E and 10-30°N were conducted. The cloud activities in and around Bangladesh were obtained in 10 by 10 grid boxes. The northwestern part of Bangladesh was largely affected by pre-monsoon clouds, while the whole country was affected by the peak monsoon activities.
The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide.
This Format and Content Guide was followed in preparing the WIPP Compliance Status Report submitted in March 1994 and will be used for the compliance documents scheduled for submittal in the Spring of 1995. The Compliance Status Report was issued to stakeholders in March 1994 and describes the status of associated activities on compliance with the requirements in Title 40 CFR 268.6 and Title 40 CFR 191. The Compliance Status Report focuses on (1) the information required for a demonstration of compliance, (2) preliminary results, (3) the areas of the WIPP program that are either not currently mature enough, or do not provide adequate margin for a demonstration of compliance, and (4) the areas of the WIPP program that will be focused upon to provide the remaining necessary information for use in the 1995 compliance demonstration reports. The Compliance Status Report is not intended to constitute a statement of compliance or a demonstration of compliance. It is intended to report the status of progress made to date in project efforts to achieve the required level of data/information necessary for the required compliance demonstrations. Comments on the Compliance Status Report from stakeholders will likely result in a modified Format and Content Guide, as will the promulgation of the EPA`s Compliance Criteria for WIPP (40 CFR 194).
Jackfruit ( Artocarpus heterophyllus Lam.) Diversity in Bangladesh: Land Use and Artificial Selection. Bangladesh is often recognized as a secondary center of diversity for jackfruit (Artocarpus heterophyllus Lam.) and is expected to harbor important genetic diversity of this underutilized tree crop. Unfortunately, genetic erosion is occurring before this rich local resource has been documented and utilized for potential crop improvement. The aim of this study was to carry out a village-based survey and make morphological measurements to document and assess jackfruit diversity across trees associated with a gradient of three locations/habitats (homesteads, public lands, and forest or fallow lands). We also tested the hypotheses that cultivated jackfruit found in homesteads exhibited positi...
We present an energy-flow model for rural family farming systems (RFFS) in LDCs such as Bangladesh. This model incorporates farming components acting as sources or sinks of energy flows in providing edible, saleable and inflammable output for sustaining the rural physical quality of life (PQL). Based on this model, the quantitative input-output structure for different energetics, as well as energy flows for the farming systems of a traditional village in Bangladesh, are presented. This system is evaluated in terms of energy-dependent indicators. (Author)
Bangladesh is one of the developing countries in the world which faces severe energy and environmental challenges. Grameen Shakti is a micro-generation renewable energy program that aims to meet energy requirements of the people of Bangladesh in a cost effective and environmentally friendly manner. It is one of the largest and fastest growing programs of its type in the world. Presently, Grameen Shakti deals with three technologies: solar home systems (SHSs), biogas systems and improved cooking stoves (ICS). This article looks into the prominent features of Grameen Shakti program which have primarily contributed to its success.
The CSC Project on Management of Water Hyacinth in Bangladesh was started in only April 1981. The present report from Bangladesh is based on the interim progress reports, submitted by the project coordinators of the organizations concerned, for the work during the short intervening period to 4th June 1981. It is obvious that the report deals mainly with the preliminary preparations and observations on the various aspects of the investigations. The research components assigned to various organisations in Bangladesh are: Bangladesh University of Engineering and Technology; - Growth rate and biogas production; Housing and Building Research Institute; - Paper and board, and biogas; Bangladesh Council of Scientific and Industrial Research - Protein, enzymes and ammoacids; Dacca University - Pollution removal and studies of biomass production. Bangladesh is a flat deltaic plain formed from old and new alluvium. The areas of old alluvium are located above the general level, while the vast areas of new alluvium are situated m the flood plain of the modern rivers. The whole country is intersected by a network of rivers; the areas comprising the alluvial plains are very large. The river bank levees are high and the land gradually slopes inland away from the levees. The tract of land between two rivers are shaped like a furrow and in most cases form elongated 'beels' or swamps which are ideal place for the growth and propagation of aquatic plants particularly water hyacinth along with other aquatic organisms, both of plant and animal origin due to eutrophication. It is in the shallow swamps and derelict ponds that luxuriant growth and proliferation of water hyacinth is generally observed in Bangladesh. However, there is a feeling that much of the water hyacinth population in the open countryside was depleted during the severe drought which prevailed during the summer of 1979. But Bangladesh has the ideal water and climatic environment for conditions of rapid growth and spread of water hyacinth and soon it may be a menace again unless economic utilization is evolved with proper management.
The per capita per year fuel consumption in Bangladesh is only 56 kg oil equivalent. The supply of electricity by Bangladesh power development board (BPDB) and Dhaka electricity supply authority (DESA) is mainly confined to cities and towns. Rural Electrification Board (REB) distributes electricity to the rural people through cooperatives. The rural cooperatives cover only 10% of the total population. Only about 15% of the total population is directly connected to the electricity. In order to meet the increasing energy demand for development of agriculture and industry and for the generation of better employment opportunities, it will be necessary to harness all the available alternative sources of energy immediately.
Emerging research suggests that the cues we glean from first impressions depend on our goals. This research uses sorority recruitment to examine whether groups that vary in social status rely on disparate cues to form first impressions of potential new group members. Current sorority members were given 500-ms to view pictures of women who wanted to join their sororities, and were then asked how likely it was that each prospective member would receive a bid from their sorority (bid expectancy). Prospective members were also rated on their attractiveness. Data were analyzed separately for high- vs. low-status houses. Results revealed that attractiveness was more predictive of liking and bid expectancy for the high-status houses, as compared to the low-status houses.
Limited historical references indicate that bull trout Salvelinus confluentus in Oregon were once widely spread throughout at least 12 basins in the Klamath River and Columbia River systems. No bull trout have been observed in Oregon's coastal systems. A total of 69 bull trout populations in 12 basins are currently identified in Oregon. A comparison of the 1991 bull trout status (Ratliff and Howell 1992) to the revised 1996 status found that 7 populations were newly discovered and 1 population showed a positive or upgraded status while 22 populations showed a negative or downgraded status. The general downgrading of 32% of Oregon's bull trout populations appears largely due to increased survey efforts and increased survey accuracy rather than reduced numbers or distribution. However, three populations in the upper Klamath Basin, two in the Walla Walla Basin, and one in the Willamette Basin showed decreases in estimated population abundance or distribution.
This report documents a study by Sandia's Systems Analysis Group to assess the status of, and need for, shipping containers to support the mission of National Nuclear Security Administration's Office of Defense Program. The focus of the study evolved into determining the status of existing packages relative to Federal Regulations for the Department of Transportation and Nuclear Regulatory Commission. Proposed regulatory changes will mandate the elimination or restricted use of many current DP packages. This study clarifies numerous misconceptions regarding these regulatory changes and status of packages relative to them. We have proposed guidelines for new package development based on the regulatory status of existing packages. Additionally, we have identified attributes that will make new packagings more amenable to accommodating new contents. This will allow the new packagings to better fill voids in container needs that are recognized but unable to be characterized at this time.
Medicine and epidemiology currently dominate the study of the strong association between socioeconomic status and mortality. Socioeconomic status typically is viewed as a causally irrelevant "confounding variable" or as a less critical variable marking only the beginning of a causal chain in which intervening risk factors are given prominence. Yet the association between socioeconomic status and mortality has persisted despite radical changes in the diseases and risk factors that are presumed to explain it. This suggests that the effect of socioeconomic status on mortality essentially cannot be understood by reductive explanations that focus on current mechanisms. Accordingly, Link and Phelan (1995) proposed that socioeconomic status is a "fundamental cause" of mortality disparities--that socioeconomic disparities endure despite changing mechanisms because socioeconomic status embodies an array of resources, such as money, knowledge, prestige, power, and beneficial social connections, that protect health no matter what mechanisms are relevant at any given time. We identified a situation in which resources should be less helpful in prolonging life, and derived the following prediction from the theory: For less preventable causes of death (for which we know little about prevention or treatment), socioeconomic status will be less strongly associated with mortality than for more preventable causes. We tested this hypothesis with the National Longitudinal Mortality Study, which followed Current Population Survey respondents (N = 370,930) for mortality for nine years. Our hypothesis was supported, lending support to the theory of fundamental causes and more generally to the importance of a sociological approach to the study of socio-economic disparities in mortality.

Currently, countries in the Middle East and North Africa are in the process of changing from high to low mortality and fertility, and the present paper reviews and assesses the current state of the social science research on family patterns and women's status in these regions. In particular, it reviews literature on: 1) marriage patterns; 2) the extended family and relations internal to the family; 3) larger kinship structures; 4) the role and status of women in the larger society; and 5) divorce, widowhood, and remarriage. The author, however, believes that much of the research on family patterns lacks concern with the impact of basic structural changes in the economic and social organization of countries in the region. He concludes by offering a few suggestions about areas where research linking population dynamics with family patterns and the status of women could be usefully undertaken. PMID:12309829
The rapid increase in world energy demand, the depletion of conventional energy sources and the pollution caused by conventional fuels have increased the importance of developing new and renewable energy sources. Additionally, technological developments have resulted in increased energy demand for the entire world, including Turkey, especially for electrical energy.

An overview of wind energy in Turkey is presented, and its currentstatus, application, support mechanisms and associated legislation in Turkey are described. Wind energy and its status in the world are also addressed. It can be concluded from this analysis that wind energy utilization in Turkey and throughout world has sharply increased. Turkey has an abundance of wind energy sources. (author)
The clinical course of patients with chronic lymphocytic leukemia (CLL) is highly heterogeneous, with some patients experiencing rapid disease progression and others living for decades without requiring treatment. Immunoglobulin heavy chain variable region (IGHV) mutation status is a powerful prognostic factor in patients with CLL. The presence or absence of IGHV mutation status is currently the gold-standard prognostic factor, but this technique is labor-intensive and costly. The expression of ?-chain-associated protein kinase 70?kDa (ZAP-70), detected by flow cytometry, has been served as a potential surrogate for the absence of IGHV mutation status since 2003. Given the current problems with the standardization of ZAP-70 assessment by flow cytometry, this chapter reviews the analysis of...
Managers faced with decisions on threatened and endangered wildlife populations often are lacking detailed information about the species of concern. Integration of genetic applications will provide management teams with a better ability to assess and monitor recovery efforts on imperiled species. The field of molecular biology continues to progress rapidly and many tools are currently available. Presently, little guidance is available to assist researchers and managers with the appropriate selection of genetic tools to study the status of wild manatee populations. We discuss several genetic tools currently employed in the application of conservation genetics, and address the utility of using these tools to determine population status to aid in conservation efforts. As an example, special emphasis is focused on the endangered West Indian manatee (Order Sirenia). All four extant species of sirenians are imperiled throughout their range, predominately due to anthropogenic sources; therefore, the need for genetic information on their population status is direly needed.
Various systemic manifestations are reported to be caused by chronic arsenic exposure in the population living in the Indo-Bangladesh subcontinent. This study from West Bengal assesses the likelihood of occurrence of hypertension (HTN) in individuals resident in an area of high groundwater contamination with arsenic (Nadia district) compared to those from a non-contaminated area (Hoogly district) in West Bengal, India. Two hundred and eight study participants (Group 1) were recruited from a cross-sectional study in six villages in the Nadia district and 100 controls (Group 2) from a village in the Hoogly district. The two groups were evenly matched in regard to age and sex. History taking and clinical examination including blood pressure measurement were undertaken in each participant. Water samples from current and previous drinking water sources and hair and urine samples from each participant were collected for estimation of arsenic. The present study shows evidence of increased association of HTN in individuals resident in arsenic endemic region compared to those from a non-endemic region in West Bengal. There were increased odds ratios for HTN [Adjusted Odds Ratio, OR, 2.87 (95 %CI = 1.26-4.83)] in Group- 1 participants compared to Group- 2 people. Within Group 1, there was no difference in prevalence of HTN between those with and without skin lesion. There was a dose-effect relationship seen with increasing cumulative arsenic exposure and arsenic level in hair and HTN in participants living in arsenic endemic region.The findings reported here support an association between arsenic exposure and HTN. More work is needed to characterize the link further. PMID:22702810
ABSTRACT: INTRODUCTION: A myoepithelial hamartoma is a very uncommon submucosal tumor of the stomach. In an atypical presentation in our case, it mimicked the clinical presentation of a gastrointestinal stromal tumor. To the best of our knowledge, it is the first case of a hamartoma of the stomach reported from Bangladesh and one of few cases described in the literature. CASE PRESENTATION: We describe the case of a 35-year-old Bengali man with recurrent epigastric pain and occasional vomiting with radiographic findings of a gut mass. An upper gastrointestinal endoscopy revealed a healed duodenal ulcer, deformed 'D' bulb and a submucosal swelling in his antrum. Ultrasonography and a contrast-enhanced computed tomography scan confirmed the presence of a well-defined, oval gut mass in his upper abdomen, compressing his duodenum. The mass had a mixed density and was considered to probably be a gastrointestinal stromal tumor. Ultrasonography-guided fine needle aspiration cytology was inconclusive. After resection at laparotomy, a histopathological examination revealed a myoepithelial hamartoma. These tumors are characterized by hypertrophic smooth muscle bands surrounding varied epithelial elements, which may be arranged in diverse patterns such as simple glandular structure, Brunner's gland, pancreatic ducts and sometimes pancreatic acini. This case report is complemented by a literature review relating to the atypical presentation. CONCLUSION: Gut masses need to be investigated thoroughly and the possibility of rare tumors should not be excluded. Although the recommended treatment for such lesions is limited resection, radical procedures such as a pancreaticoduodenectomy are often performed when the lesion occurs in the periampullary area because of preoperative misdiagnosis as a carcinoma. Therefore, it is essential for clinicians to maintain current knowledge of the lesion to avoid inaccurate diagnosis and prevent unnecessary surgery. PMID:23146179
An attempt is made to identify seismicity patterns precursory to great earthquakes in most of Tibet as well as the central and eastern Himalayas. The region has considerable tectonic homogeneity and encompasses parts of China. India, Nepal, Bhutan, Bangladesh, and Burma. Two seismicity patterns previously described were used (1) pattern ..sigma.. is a peak in the sum of earthquake energies raised to the power of about 2/3, taken over a sliding time window and within a magnitude range less than that of events we are trying to predict; and (2) pattern S (Swarms) consists of the spatial clustering of earthquakes during a time interval when the seismicity is above average. Within the test region, distinct peaks in pattern ..sigma.. have occurred twice during the 78-year-long test period: in 1948--49, prior to the great 1950 Assam-Tibet earthquake (M=8.6) and in 1976. Peaks in pattern S have occurred three times; in 1932--1933, prior to the great 1934 Bihar-Nepal earthquake (M=8.3), in 1946, and in 1978. The 1934 and 1950 earthquakes were the only events in the region that exceeded M=8.0 during the test period. On the basis of experience here and elsewhere, the current peaks in both ..sigma.. and S suggest the likelihood of an M=8.0 event within 6 years or an M=8.5 event within 14 years. Such a prognostication should be viewed more as an experimental long-term enhancement of the probability that a large earthquake will occur than as an actual prediction, in view of the exceedingly large area encompassed and the very lengthy time window. Furthermore, the chances of a randomly occurring event as large as M=8.0 in the region are perhaps 21% within the next 6 years, and the present state of the art is such that we can place only limited confidence in such forecasts.
Improved energy supply is essential for socio-economic development and environmental sustainability. It has a direct impact on the life situation of the rural poor, influencing their productivity, health, education, and gender-related issues. The present report compiles the findings of a study carried out on behalf of the sector project Poverty-Oriented Basic Energy Services of the German Technical Cooperation in collaboration with the Sustainable Energy for Development Programme in Bangladesh. The contribution under consideration assessed the impacts and the poverty orientation of both the Solar Home System and the Improved Cook Stoves interventions as well as the sustainability of the dissemination structures for these technologies. Access to solar electricity was found to enhance the general life quality of Solar Home System owners, a great majority of whom named improved lighting as the most important benefit. Improved study conditions for children and more customers are related benefits that were classified as second most important by domestic and commercial users, respectively. Recommendations given with respect to the Solar House System intervention include minor reconsiderations of how grants shall be targeted and phased out, as well as how different local capacity building measures are better geared towards enhancing user satisfaction, creating job opportunities and improving the local availability of Solar House Systems supply and know-how. The study suggests the establishment of result-oriented monitoring involving an exchange between Solar House System users and providers, enabling the latter to assess their own institutional development. Moreover, the study advises the maintenance of the current hire-purchase model but also the development of more flexible pro-poor payment for Solar House System batteries combined with a strengthening of incentives for recycling.

The authors explore the currentstatus of the economic interest definition by examing the Internal Revenue Code, the regulations, and recent related tax cases. They also update the Internal Revenue Service's current position by reviewing recent revenue rulings, but conclude that new regulations are needed to update the Palmer test of 1933. The factor of risk should be emphasized as the only one needed as long as the risk involves production and quantity or price uncertainty. 1 table.
The paper reviews the currentstatus of methods for calculating intermolecular interactions between biopolymer units. The nature of forces contributing to the various domains of intermolecular separations is investigated, and various approximations applicable in the respective regions are examined. The predictive value of current theory is tested by establishing a connection with macroscopic properties and comparing the theoretical predicted values with those derived from experimental data. This has led to the introduction of a statistical model describing DNA.

IceCube, currently under construction at the South Pole, will be a gigaton detector for high-energy neutrinos and muons. Half of the 5000 optical modules that make up IceCube are now installed in the ice and taking data. The main goal is to find high-energy neutrinos from distant astrophysical sources such as active galactic nuclei and exploding massive stars. I will describe how the detector works, show some current results and discuss status and future plans for the project.
The high brightness and short pulse duration of soft x-ray lasers provide unique advantages for novel applications. Imaging of biological specimens using x-ray lasers has been demonstrated by several groups. Other applications to fields such as chemistry, material science, plasma diagnostics, and lithography are beginning to emerge. We review the currentstatus of soft x-ray lasers from the perspective of applications, and present an overview of the applications currently being developed.
This paper reviews the status of heating systems for the TFCX-S (all superconducting coil) and TFCX-H (hybrid coil) options. Three systems were defined; preheating (electron), current drive, and bulk (ion) heating. Application of systems engineering techniques facilitated fruitful discussions of requirements and their impact on equipment between physicists and engineers. A low-cost, flexible combination of systems allows plasma experiments using all rf startup and current drive.

The diurnal variation of precipitation over the Bengal region is numerically investigated using a non-hydrostatic mesoscale model. We focused on northeastern Bangladesh, where the maximum of late night-early morning precipitation is observed. Simulated characteristics of diurnal variation of precipitation agree, to a large extent, with observable evidence. The mechanism of the high late night-early morning precipitation in a case of June 14 to 21 is investigated using the model results.At night, strong southwesterly monsoon winds transport a large amount of moisture over Bangladesh. This high equivalent potential temperature (?e) air mass climbs the slope of the Meghalaya Plateau or climbs over a deep (several hundreds meters to 1 km) pool of cold air, and triggers precipitation over northeastern Bangladesh. The triggered systems develop into mesoscale squall lines and propagate southward or south-southwestward at a speed of about 10 m s-1. It is found that the katabatic mountain wind is not a major player in the diurnal variation of precipitation over the northeastern Bangladesh area.
