  The Zn1-xCdxS (0≤×≤1) thin films have been prepared using a low cost and simple spray pyrolysis technique onto preheated glass substrates at temperature 523 K. The surface morphology, structural, optical and electrical properties of the as-deposited and annealed Zn0.20Cd0.80S films were studied by optical microscopy, Energy Dispersive X-ray (EDX), X-Ray Diffraction (XRD), UV-visible spectroscopy and Vander Pauw method, respectively. The films are shown inhomogeneous surfaces, less defined grain boundaries. The elemental analysis (EDX) revealed that the deposited films are of Zn, Cd and S compositions. X-ray diffraction patterns indicated that the as-deposited films are amorphous in nature and the annealed film is found to be crystalline structure. The average grain size of the annealed film is found to be 8-47 nm and its value increases with the increase of annealing temperature. Various optical constants viz., optical band gap, extinction coefficient, refractive index and dielectric constant have been studied. The direct optical band gap energy of the as-deposited and annealed films is varied from 3.64-2.40 eV and 2.62-2.1 eV, respectively. The dc electrical conductivity increases with the increase of temperature and also with Cd doping.

  The present study was undertaken to determine the effect of capacity building on household expenditure and nutrition of farmers in Bangladesh. A field survey was conducted in three districts of Bangladesh between April 2006 and March 2007. The study areas have similar geographical and climatic conditions and land is equally suitable for vegetables, rice and other crops like oilseeds. The farmers with high capacity building ability earn more income than the farmers of low capacity building category. The additional income earning is associated with the improvement of technical, social, natural and human capital of farmers. The farmers with high capacity building category changes their household expenditure pattern to uptake a balanced nutrition. They are able to uptake balanced nutrition reducing their consumption expenditure percentages and invest their money in productive areas which increases their per capita income and savings. Therefore, capacity building influences positively the balanced nutrition of the farmers changing their consumption expenditure pattern.

  Globally, the prevalence of chronic, noncommunicable diseases is increasing at an alarming rate and diabetes is one of them. If diabetes is not controlled then a lot of complication like coronary artery disease, cerebrovascular disease, peripheral vascular disease, retinopathy, nephropathy and neuropathy arise in diabetic patients and causes morbidity and/or mortality. Diabetes is increasing at an epidemic form and in near future the largest increases will take place in the regions dominated by developing economies. So, it will be a great social and economical burden to developing countries as well as the developed. But if we be aware about our diet and lifestyle and take proper medication we may prevent and reduce the prevalence of diabetes. Oral medicine plays an important role in management of diabetes. But most of the oral drugs are costly and have a lot of side effects. For this it is also necessary to take medicines with fewer or no side effects. And antidiabetic medicinal plants may play an important role in this case. In this article we have tried to describe how diet and lifestyle with using medicinal plants may help to prevent or maintain diabetes and help to reduce the mortality and morbidity due to diabetes or complication related to it.

  Non-conventional seafood products, fish sausage and fish ball were developed from underutilized sea catfish and consumer’s acceptance and market test of the new products were conducted in inland rural and coastal fishing communities. Sea catfish, achysurus thalassinus was collected from Chittagong in an insulated box. The cost of production and profit of the products were assessed in the laboratory of the Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh, Bangladesh. From a 1000 g catfish, 500 g washed mince could be recovered. From 500 g washed mince, a total of 1000 g dough could be produced and from this dough 17 pieces of fish sausage and 40 pieces of fish ball were produced. The total production cost of the products from 1000 g dough including raw materials, ingredients, wage, transportation, storage and marketing was Tk. 75. Pilot market-testing were done in 10 villages of Mymensingh and six coastal villages of Chittagong. Finally, an analysis of the cost and profit of production was done on the basis of the price of product set by the people, the price of raw material in the market, tentative cost of productions and cost of transportation and storage. As per the average selling price obtained from the market tests, products of 1000 g can be sold at Tk. 136/- for sausage (Tk. 8/- each) and Tk. 160/- for fish ball (Tk. 4/- each) in the rural market of Bangladesh. Therefore, a net profit of Tk. 61 from fish sausage and Tk.85 from fish ball could be realized, from a manufacture of 1000 g whole sea catfish. Consumer’s acceptance and market tests revealed that fish ball was best chosen between the two products.

  Present study examined the marketing system’s of broiler farming in Gazipur district and analyzed marketing costs, margin and profits of retailers. It may be concluded from the study that the producers sold broilers to the retailer at farm level. The retailers sold 80 percent of their live broiler to consumers and 20 percent to the institutional buyers in the market. All of the selected sample producers sold live broiler to retailers at the farm level in the study area, because they are: too far from retailers/consumers, are not able to do what is required and are too small as regards output.
Respondent producers and retailers viewed that fluctuation in supply and demand and also in price are major problems for marketing on broiler. Retailers were not affected by the price fluctuation but broiler producers were severely affected by the downward swing of price fluctuation. Proper measures for solutions of the problems will help to develop broiler farming which intern will increase family income and also creation of employment opportunities in the country. More detailed study is required about the marketing system of broiler intermediaries and their costs, margin and profits before making final recommendation.

  This paper examines the extent of adoption of modern technology in Bangladesh and knowledge gap of the farmers about the technology. It was found that 100% of wheat acreage in the country were planted to modern varieties. Wheat area, production and yield in the country increased by 10, 14 and 3.5% per annum during 1971-92. The farmers found to have moderate knowledge gap in most of the practices of modern wheat technology. However, high knowledge gap was observed for recommended fertilizer dose. There were significant difference between the practices recommended and the existing knowledge of the farmers for different production practices. The demonstration farmers of farming system research sites and multi-location testing sites had less knowledge gap than the other farmers. Wheat planting before November is not recommended, late planting is one of the main causes of lower yield of wheat in Bangladesh. Wheat planting after November reduces the yield at the rate of 1.3% per day of delay. The overall data showed a significant difference between the practices recommended and existing technological knowledge of the farmers.

  The present study was designed to determine the wheat supply response to selected factors and to analyze the short run and long run supply responses of wheat in Bangladesh. Time series data from 1972-73 to 1998-99 have been used in the analysis. Econometric and statistical techniques were used to estimate the supply response of wheat at the national level. The price responses of wheat supply under the partial adjustment (PA) model were 0.67 in the short run and in the long run this was 1.06 and was statistically significant. Similarly, the response of wheat supply to lagged irrigation was relatively higher, which was 1.11 in the short run and in the long run it was 1.76. Besides, this was highly significant at 1 per cent level. The adjustment coefficient was 0.63 in the wheat sector during the period. The results indicate that the implementation of a farm price support policy could be used to manipulate wheat supply in Bangladesh. If public expenditures were geared properly to build irrigation infrastructure, it would give positive impacts on wheat supply in the country. If the government would follow a price stabilization policy, it would reduce price risk and would produce a positive impact on wheat supply situation in Bangladesh.

  Two types of dahi were prepared. One type was prepared by using 10, 20 and 30% banana juice with whole milk and another one (plain dahi) was prepared by using whole milk only. Dahi samples were stored both in room temperature and refrigeration temperature until deterioration. During storage samples were analyzed for getting the organoleptic quality (Smell and Taste, Body and Consistency, Colour and Texture), percentage of acidity and pH value. Organoleptic quality and pH value of different types of dahi samples decreased but acidity percentage increased during storage at both room and refrigeration temperature. Plain dahi was in good condition up to 3 days of storage period and banana juice based dahi was up to 2 days only at room temperature. On the other hand, at refrigeration temperature plain dahi was suitable for consumption up to 12 days and banana juice based dahi was up to 8 days. Keeping quality of banana juice based dahi was lower than that of plain dahi both under room and refrigeration temperature.
