Successful development of bioblends requires that the biodegradable polymers be compatible with other component biodegradable/synthetic (non-biodegradable) polymers. Bioblends from LLDPE and gelatin were prepared by extrusion and hydraulic heat press technique. The gelatin content in the bioblends was varied from 5 to 20 wt%. Various physico-mechanical properties

This paper analyzes data from the 1998 Mid-Term Evaluation of the Bangladesh Integrated Nutrition Project (BINP) to identify the determinants of pregnancy food consumption. The analysis found that

Efficient technique for medical diagnosis is defined to provide better chance of a proper treatment. In this paper, we present a new parallel processing architecture to perform medical detection that uses multiple ultra-sono-graphic features and a diagnostic algorithm for identifying breast nodule malignancy. The algorithm has been implemented in the first phase without breaking them into macro-blocks, and in the next phase after breaking the frames into the respective macro-blocks. MATLAB has been used for the simulation of the algorithm and the results obtained are presented in this paper. We have also done the simulation and FPGA based synthesis of the proposed architecture for the most commonly used target hardware to analyze the hardware cost.

Different made tea brands were collected randomly from different super shop of Dhaka city. The Association of Official Agricultural Chemists (AOAC), 2005 was used as official methods of analysis. The Standard Plate Count (SPC) technique was used for total microbial load, yeast and fungal count. Most Probable Number (MPN) technique was used for the enumeration of coliform in tea samples. Bacteria, yeast, mould and coliform were observed before and after boiling in all studied the samples. Before boiling, total microbial load and coliform were found at significantly higher of its’ acceptable limit (p<0.05) whereas yeast and fungus were found of its’ acceptable limit (p>0.05). After boiling, only coliform was observed significantly higher in all except Tetley tea at its’ non-acceptable limit (p<0.05). Fec...

The results are explained in terms of fluxoids and rapid variation of the penetration depth near and below Tc. The microwave absorption increases as a function of the magnetic field as a result of increase in the surface area of the normal-conducting region. By applying a modulating field in a particular manner and from thermodynamic considerations there are strong indications of energy absorption by fluxoids.

Micronutrient gaps (the difference between micronutrient requirements and actual micronutrient intake) were estimated for four groups of project beneficiaries, with target intakes defined as requirements for iron, calcium, zinc, vitamin A, vitamin C, riboflavin, niacin, and vitamin B12 recommended by the Food and Agriculture Organization/World Health Organization. Primary focus was placed on iron and vitamin A. Cost and bulk constraint analyses, based on cost of supplement, feasibility of delivery, and serving volume needed to achieve micronutrient targets, were used for comparing the supplement options. In terms of these analyses, the micron...

However, serum hepatic enzyme activity as recognized on liver function tests (LFTs) showing a dose-response relationship with arsenic exposure has not yet been clearly documented. The aim of our study was to investigate the dose-response relationship between arsenic exposure and major serum enzyme marker activity associated with LFTs in the population living in arsenic-endemic areas in Bangladesh. A total of 200 residents living in arsenic-endemic areas in Bangladesh were selected as study subjects. Arsenic concentrations in the drinking water, hair and nails were measured by Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The study subjects were stratified into quartile groups as follows, based on concentrations of arsenic in the drinking water, as well as in subjects' hair and nails: lowest, low, medium and high. The serum hepatic enzyme activities of alkaline phosphatase (ALP), aspartate transaminase (AST) ...

Weights of around 1700 children aged 2 60 months in five villages of Matlab, Bangladesh, were taken during the first half of 1981. The children were followed for 18 months and their survival was recorded. The severely malnourished children had a risk of death nine times that of their counterparts with better nutritional status. Female children had a higher risk of death than the males. Mother&amp;amp;#39;s education and economic condition of household also showed negative relationships with the risk of death, but the effect of mother&amp;amp;#39;s education was modified by economic condition and sex of the children.
