Although morphologically corresponding with what is currently defined as E. alcocki, the color pattern of the carapace of the present specimen is rather different from that of the Chinese material-only the anterior fifth of the carapace is marked with scattered red spots, the rest of the surface is yellowish, with four unusually shaped red blotches which almost look like Sanskrit characters.展开更多

The objectives were to ensure better land utilization, break up the mono cropping, improve soil health, and generate extra-income for small and resource-poor farmers of Bangladesh. Crop compositions used in the experiments were monsoon-rice （cv. BRRIdhan-32, BRRldhan-39 and BINAdhan-4） followed by pulses （grasspea, chickpea and field pea） followed by spring-rice （cv. BRRldhan-28, BRRldhan-29 and BINAdhan-6）. Based on the data from two years in a pooled analyses, it was observed that monsoon-rice variety BINAdhan-4, followed by field pea （as vegetable ＆ forage） and spring-rice variety BINAdhan-6 produced the highest yields of 5.0 t ha-1 rice grain, 3.25 t ha1 （green vegetable） ＋ 18.1 t hal （forage） legumes and 7.8 t ha~ rice grain, respectively. The cropping pattern of monsoon-rice （BINAdhan-4）-field pea （as vegetable ＋ forage）-spring-rice （BINAdhan-6） gave the highest net return of USD$1,705 hal year-~ compared to other patterns with different rice varieties and chickpea and grasspea. This is a new finding, and is being practiced by farmers of Bangladesh who have enhanced their farm income substantially. This has also generated job opportunities for rural women to pick the green vegetable of field pea.展开更多

Bangladesh has made major strides in its human development index （HDI）, population growth rate achieved to 1.3%, gross domestic product （GDP） over the last five years achieved more than 5% growth consecutively; as a result, it mooted the Brazil, Russia, India, China （BRIC） successors, otherwise known as the Next-11. The success has come through the miracle activities of micro finance （MF： Grameen Bank and non-governmental organizations （NGOs））, remittance from migrant worker （RMW）, and export of readymade garment （ERMG） products. These three （MF, RMW, and ERMG） as the ＂prime powers＂ or engines have been achieving to ＂bottom up＂ of social economic development. This paper reviews aspects of economic development in Bangladesh, analyzes three prime powers, and tries to find out a development pattern, vis-a-vis construct Bangladesh economic development model or BED model. Finally, this paper examines Bangladesh＇s development experience in light of the BED model. It has recognized MF model for poverty alleviation in the worldwide.展开更多

Yet, while Bangladesh has had a long history of university teaching, pedagogy has hardly entered the imagination of university educators. At the university level, pedagogical training would address cultural hindrances to students＇ advanced learning. Today＇s teachers are yesterday＇s students, with each generation being groomed in the same cultural patterns of learning that are continually repeated without examination. At the same time, the majority of faculties lack pedagogical methods for adjusting their teaching framework to accommodate the diversity of students＇ worldviews to nurture knowledge progression in classroom settings. Importantly, students acquire cultural practices of rote learning and memorization by way of lectures and homework that parrots texts and lectures. Many faculties are unaware that the purpose of a university is to stimulate new ideas and knowledge, provoke assumptions, and teach and encourage critical thinking. The pedagogical challenge also derives from Bengali culture, from which teachers assume a hierarchical mindset and attitude that is counter-productive to students＇ learning.展开更多

The weather dependent variation of demand, especially where the weather is severe in nature, requires a significant reserve margin of the generation system. The evaluation of the weather dependent component of the electric demand is the basic tool for the planning of the reserve margin. This paper evaluates the weather dependent portion of the load of BPS （Bangladesh power system）. The evaluation of the weather dependent portion of the demand is based on the EMD （empirical mode decomposition） technique.展开更多
