Factors Influencing the Extent of Practice of Organic Farming Technologies: A Case Study of Tangail District in Bangladesh

The study was attempted to explore the major factors influencing the extent of practice of organic farming technologies (called OFTs from here) by the Bangladeshi farmers. The empirical data for the study were collected from the organic farmers of the selected villages of Tangail district in Bangladesh. The results of the study identified four factors like development of knowledge and awareness regarding environmental issues, creation of health awareness, and simplicity of the OFTs and availability of basic production factors as the major influential factors which can increase the extent of practice of OFTs by the farmers. Taking these factors into account the policy makers can formulate a strategy to increase the extent of practice of various OFTs by the farmers for the successful expansion of organic farming in Bangladesh

Practical Use of Soybean Meal and its Supplementation With Amino Acids in Diet of Mystus Nemurvs (Cuvier and Valenciennes) Fingerlings

Two experiments using different formulation of diets to determine the suitability of soybean meal in diet for Mystus nemurus fingerlings were carried out. In the first experiment, seven types of formulated diets were used to evaluate the effect of partial or complete replacement of fishmeal (FM) with solvent-extracted soybean meal (SSBM) and full-fat soybean meal (FFSBM) for the river catfish, Mystus nemurus fingerlings. Six isonitrogenous diets (42% crude protein) containing different content of FM:SSBM were D1(61.29:0.0%), D2(39.78:30%), D3(32 .6:40%), D4(25 .44:5 0%), Ds(18.37:60%), and D6(O.O:85.84%) were randomly fed to catfish in triplicate tanks. The seventh diet (30% crude protein) containing 0% FM and 85.42% FFSBM was also used in the same manner. Average individual weight gain, feed conversion ratio, specific growth rate, protein efficiency ratio, and yield were not differ significantly (p>0.05) among the two comparable diets CDI and D4) where the FM and SSBM percentage were 6 1 .29, 2 5 .44 and 0, 50%, respectively. But apparent net protein utilization (between DJ and D4) was d iffering significantly (p<0.05). Survivability of the fish fed diet DJ and diet D4 with the value of 8 1 .90 and 80.95%, respectively. Th is study indicate that 5 8.49% FM can be replaced by S SBM i n the diets for better growth for intensive culture. In the second experiment, seven types of isonitrogenous (42% protein) diets having fish meal with soybean meal (Control diet) and different proportion of soybean meal supplemented with three selected ind ispensable crystalline amino acids were used to determ ine their suitability as feed for Mystus nemurus fingerlings under close water recirculating system . Casein was added to make up 42% protein. The study showed that M nemurus fed the control diet CD) with 25.44% FM and 50% S SB M (same as in experiment 1) had highest growth performances. The species fed the diet with 57% SSBM (D3) with the selected amino acids had the second highest growth performances. But between the two treatments CD) and D3) had no significant differences (P>0.05) on the basi s of weight gain (%), FeR, SGR, PER, yield and surv ival. Amino acid profiles of whole-body M nemurus fingerlings at different feed ing trials were determined to provide baseline information on the amino acid requirements of the fresh water catfish. The essential am ino acid (AlE) ratio were calculated and found to be a possi ble method for evaluating the M nemurus diet, as a superior ratio i ndicates superior production

This study aims to examine to understand how Rohingya refugees consider their health perception and post-resettlement health realities in the Atlanta metropolitan area, USA. Through the theoretical lens of medical pluralism, practice theory, therapy management network, this study determines what factors facilitate them to seek health-care in the USA. In this study, data was gained by interview, key informant interview, observation, case study, and Autoethnography methods

Detection of Road Conditions Using Image Processing and Machine Learning Techniques for Situation Awareness

In this modern era, land transports are increasing dramatically. Moreover, self-driven car or the Advanced Driving Assistance System (ADAS) is now the public demand. For these types of cars, road conditions detection is mandatory. On the other hand, compared to the number of vehicles, to increase the number of roads is not possible. Software is the only alternative solution. Road Conditions Detection system will help to solve the issues. For solving this problem, Image processing, and machine learning have been applied to develop a project namely, Detection of Road Conditions Using Image Processing and Machine Learning Techniques for Situation Awareness. Many issues could be considered for road conditions but the main focus will be on the detection of potholes, Maintenance sings and lane. Image processing and machine learning have been combined for our system for detecting in real-time. Machine learning has been applied to maintains signs detection. Image processing has been applied for detecting lanes and potholes. The detection system will provide a lane mark with colored lines, the pothole will be a marker with a red rectangular box and for a road Maintenance sign, the system will also provide information of aintenance sign as maintenance sing is detected. By observing all these scenarios, the driver will realize the road condition. On the other hand situation awareness is the ability to perceive information from it’s surrounding, takes decisions based on perceived information and it makes decision based on prediction

Effect of Phytate Phosphorus on the Utilisation of Rice Bran in Broiler Chickens)

Rice bran (RB) is a by-product of rice milling industry and is produced in many parts of the world including Malaysia. It is a high energy source for both ruminant and nonruminant animals with a crude protein content of 12-13%. Its fibre content is about 7-16%. Rice bran is also rich in phytate phosphorus (pP) which is not easily available to poultry. This study examines the utilisation of pP by broiler chickens fed RB based diets at the finishing stage. The role of phytase enzyme and vitamin D3 in improving the utilisation of pP was also examined. Two growth trials were carried out with 21 day-old broiler chickens to determine the effects of replacing com with RB on their performance. It was found that the performance of birds were adversely affected when RB was included at 45% level. The results obtained from these two studies suggest that RB can be included up to 35% in the diet of broiler chicken without any adverse effects on their performance

Identifying Potential Factors of Childbearing in Bangladesh

This paper aims to identify different potential factors associated with childbearing pattern among the ever-married women in Bangladesh. Childbearing pattern is directly related to fertility level and rapid population growth is the major consequence of more childbearing. Bearing more children affects adversely on social and economic opportunities and produces substantial risks to the health of mothers and children. Bangladesh Demographic Health Survey data 1999-2000 and 2004 have been used for this study. First bi-variate analysis method is carried out to identify different factors associated with childbearing. Then generalized linear modelling approach has been performed to quantify the simultaneous effect of key socio-economic and demographic factors. Our primary findings show that childbearing varied tremendously by education level and age at first marriage. From the generalized linear model analysis, mother's age group, types of place of residence, division, media exposure are found to be significantly associated with bearing more children among the ever-married women in Bangladesh. These findings suggest that government should continue its effort to ensure higher education for females and to promote to delay age at marriage

Benefit-Cost Assessment of Different Homestead Vegetable Gardening on Improving Household Food and Nutrition Security in Rural Bangladesh

Homestead vegetable gardening can play a significant role in improving food security for the resource poor rural households in developing country like Bangladesh. The present study quantifies costs/benefits of traditional and developed homestead vegetable production systems, and analyzes the underlying factors contributing to food security. The result suggests that developed gardening has better performances in terms of calorie intake and economic performances over traditional but the optimal calorie intake with least-cost technology could be a feasible livelihood strategy for resource poor people. The result also suggests that education, sex, and garden area have significant effect on food security. The occupation and family size are also positively associated with food security.Community/Rural/Urban Development, Food Security and Poverty,

Protection of Bangladesh waters against accidental oil pollution from ships

Bangladesh, as being a flag, coastal and port state, has a genuine concern about the threat of oil pollution from marine transportation in its waters. However, her concern for accidental oil pollution from ships is not adequately matched by appropriate preventive and remedial measures. As a result, the country continues to be in an absolutely vulnerable position with respect to the dangers of oil pollution. This dissertation is a study of the need for and the ways of protecting the marine environment of Bangladesh from oil pollution incidents. The threats of accidental spills in Bangladesh waters are discussed and the present marine environment protection framework and oil spill response arrangements are briefly examined. A critical appraisal of the response to a past oil spill incident is given and major areas of concern and tasks to be undertaken are identified. Finally, conclusions are drawn on the basis of the study and a number of recommendations are made for enhancing the effectiveness of the existing marine environment protection framework and national arrangements for oil spill response
