Khulna, Bangladesh

Khulna University is a public university in Bangladesh. It is situated at Gollamari, Khulna, Bangladesh, by the river Moyur, beside the Khulna-Satkhira highway. The academic programs of Khulna University started on 31 August 1991 with only 80 students in four disciplines. Khulna University has 22 disciplines under five schools and one institute. It is the only university in Bangladesh where student politics is not allowed.There is also no session jam which has created a stable facility of study. Students passing Higher Secondary Certificate examination are very much interested in their admission in Khulna University for this politics-free, session-jam free environment. Khulna is an administrative Division as well as the third largest metropolitan city in Bangladesh. The Mongla Sea Port, the Shipyard, the Bangladesh Naval Base are in Khulna. Khulna is well known as industrial city and famous for the Sundarbans. Wikipedia.

Improving health services is a crucial issue and an immense challenge for the government of any Third World country. Bangladesh lacks healthcare services, one of the basic necessities of life. This paper demonstrates a method for estimating the geographical accessibility of health facilities by population coverage, average travel time and distance to the closest hospital. This analysis was applied to community units in the research area, allowing geographical access to be linked to people. The study area was divided into hexagons of equal size, and accessibility was measured from the centre of each hexagon. Despite the abundance of evidence on the inadequacy of health services in Khulna City, this study has given us a diverse dimension of possibilities. The study found that even with existing health facilities, discontent about the unavailability of health services can be mitigated in most areas. Exceptions are some peripheral areas, where average travel time to reach the city centre and distance from hospital services is greater. Source

Bone Research

Transforming growth factor-beta (TGF-β)/bone morphogenetic protein (BMP) plays a fundamental role in the regulation of bone organogenesis through the activation of receptor serine/threonine kinases. Perturbations of TGF-β/BMP activity are almost invariably linked to a wide variety of clinical outcomes, i.e., skeletal, extra skeletal anomalies, autoimmune, cancer, and cardiovascular diseases. Phosphorylation of TGF-β (I/II) or BMP receptors activates intracellular downstream Smads, the transducer of TGF-β/BMP signals. This signaling is modulated by various factors and pathways, including transcription factor Runx2. The signaling network in skeletal development and bone formation is overwhelmingly complex and highly time and space specific. Additive, positive, negative, or synergistic effects are observed when TGF-β/BMP interacts with the pathways of MAPK, Wnt, Hedgehog (Hh), Notch, Akt/mTOR, and miRNA to regulate the effects of BMP-induced signaling in bone dynamics. Accumulating evidence indicates that Runx2 is the key integrator, whereas Hh is a possible modulator, miRNAs are regulators, and β-catenin is a mediator/regulator within the extensive intracellular network. This review focuses on the activation of BMP signaling and interaction with other regulatory components and pathways highlighting the molecular mechanisms regarding TGF-β/BMP function and regulation that could allow understanding the complexity of bone tissue dynamics. © 2015 Sichuan University All rights reserved.

We develop a Socioeconomic Vulnerability Index (SeVI) for climate change affected communities in seven unions. 11Lowest tier of Local Government in Bangladesh. of Koyra upazilla. 22Sub-district. in south-western coastal Bangladesh. We survey 60 households from each union to collect data on various vulnerability domains and socioeconomic indicators. The SeVI aggregate these collected data using a composite indicator index, where a relative weight is assigned to each indicator with a view of obtaining weighted average index scores for different vulnerability domains in different unions. Results suggest that southern and south-eastern unions are relatively more vulnerable, which are the most exposed to natural hazards and mostly surrounded by the mangrove forest Sundarbans. Furthermore, social, economic and disaster frequency are found as more influential indicators to adaptive capacity, sensitivity and exposure respectively in Koyra. This pragmatic approach is useful to figure out and monitor socioeconomic vulnerability and/or assess potential adaptation-policy effectiveness in data scarce regions by incorporating scenarios into the SeVI for baseline comparison. © 2013 Elsevier Ltd.

This study determines the factors that influence rice residue burning in the field. We consider the southwest region of Bangladesh as the study site. Our results indicate that while straw length, low-elevation land, and distance of the plot from homestead positively and significantly influence the rice residue burning decision, residue price negatively and significantly influences the residue burning decision of farmers. Our study proposes subsidies for the purchase of new varieties of seeds and/or education in order to persuade farmers to move to short-straw varieties on high/medium-elevation lands as policy interventions for handling the residue burning issue. Another option might be to switch from residue burning to incorporation. Research and development efforts into shortening straw length and shortening the time period between planting and harvesting time are among other options that would mitigate the problem under consideration. © 2013 Elsevier Ltd.

Waterlogging is a widespread limiting factor for wheat production throughout the world specially irrigated and high rainfall environments. The important biological consequence of waterlogging is the deficiency (hypoxia) or complete absence (anoxia) of oxygen in soil environment which restricts the growth, development and finally yield in wheat. The tolerant genotypes of wheat can adapt to transient waterlogging by developing mechanisms related to morphology and metabolism to cope with the stress. The morphological mechanisms include the development of adventurous roots with well formed aerenchyma and sometimes with a barrier for ROL. Aerenchyma is a continuous gas filled channel, which provides a low resistance internal pathway for the movement of O2 from the aerobic shoots to anaerobic roots to respire aerobically under hypoxia or anoxia. However, lack of oxygen induces the anaerobic roots to shift the energy metabolism from aerobic to anaerobic mode. Greater activities of glycolytic and fermentative enzymes, increased availability of soluble sugars, and involvement of antioxidant defense mechanism against post-stress oxidative damages are the main metabolic mechanisms for waterlogging tolerance in wheat.
