Social Business in Bangladesh: A Study on Grameen Danone Shokti+ Yogurt

Agricultural Sciences 2022年第7期13卷 841-854页

作者： Zarin Tasnim Maruf Uddin Chowdhury mohammad Ataur Rahman mohammad abul monsur Department of Agricultural Finance & Banking Bangladesh Agricultural University Mymensingh Bangladesh Bangladesh Rice Research Institute Gazipur Bangladesh

Social business is becoming popular worldwide as a sustainable and innovative solution to tackling pressing social problems. The Grameen Danone Food Ltd. (GDFL) Shokti+ yogurt business was chosen as a social business case study. The study described GDFL Shokti+ yogurt production, pricing, and distribution process, elucidated consumers’ perception of the Shokti+ yogurt, identified the major problems faced by the consumers, and proposed probable solutions to popularize the yogurt among the consumers. The study’s objectives were achieved using descriptive statistics based on a quantitative survey of 60 consumers. The study found that Shokti+ yogurt is distributed primarily through four channels: modern model, urban trade, rural trade, and direct trade. The study revealed that non-poor households consume more Shokti+ yogurt than poor households. The findings showed that about 78% and 95% of respondents were satisfied with the yogurt quality and availability, respectively. About 17% of respondents perceived that Shokti+ yogurt is superior to regular yogurt. However, about 58% of respondents claimed that the price is higher than the amount and quality offered. Excessive liquidity, increased price, and lack of trust in the nutritional quality of yogurt were some major problems identified by the consumers. The study proposed certain recommendations such as maintaining the consistency of the yogurt, increasing the amount of yogurt sold, making the yogurt more affordable for poor consumers, and raising awareness about its nutritional benefits for popularizing Shokti+ yogurt in Bangladesh.

Impact of industrial effluent on growth and yield of rice(Oryza sativa L.) in silty clay loam soil

Journal of Environmental Sciences 2015年第4期27卷 231-240页

Degradation of soil and water from discharge of untreated industrial effluent is alarming in Bangladesh. Therefore, buildup of heavy metals in soil from contaminated effluent, their entry into the food chain and effects on rice yield were quantified in a pot experiment. The treatments were comprised of 0, 25%, 50%, 75% and 100% industrial effluents applied as irrigation water. Effluents, initial soil, different parts of rice plants and post-harvest pot soil were analyzed for various elements, including heavy metals. Application of elevated levels of effluent contributed to increased heavy metals in pot soils and rice roots due to translocation effects, which were transferred to rice straw and grain. The results indicated that heavy metal toxicity may develop in soil because of contaminated effluent *** metals are not biodegradable, rather they accumulate in soils, and transfer of these metals from effluent to soil and plant cells was found to reduce the growth and development of rice plants and thereby contributed to lower yield. Moreover, a higher concentration of effluent caused heavy metal toxicity as well as reduction of growth and yield of rice, and in the long run a more aggravated situation may threaten human lives,which emphasizes the obligatory adoption of effluent treatment before its release to the environment, and regular monitoring by government agencies needs to be ensured.

Rice science 2016年第4期23卷 211-218页

作者： Mir Sharf Uddin AHMED mohammad KHALEQUZZAMAN Md.Khairul BASHAR abul Kalam mohammad SHAMSUDDIN Genetic Resources and Seed Division Bangladesh Rice Research Institute HarvestP lus International Centre for Tropical Agriculture Department of Genetics and Plant Breeding Bangladesh Agricultural University

Thirty-one duplicate and similar named rice germplasms of Bangladesh were studied to assess the genetic variation for the agro-morphological and physico-chemical traits and simple sequence repeat banding patterns during 2009–2012 at Bangladesh Rice Research Institute. The range of variations within the cultivar groups showed higher degree. The principal component analysis showed that the first five components with vector values > 1 contributed 82.90% of the total variations. The cluster analysis grouped the genotypes into four clusters, where no duplicate germplasm was found. The highest number(11) of genotypes was constellated in cluster I and the lowest(3) in cluster II. The intra- and inter-cluster distances were the maximum in cluster I(0.93) and between clusters I and IV(24.61), respectively, and the minimum in cluster IV(0.62) and between clusters I and III(5.07), respectively. The cluster mean revealed that the crosses between the genotypes of cluster I with those of clusters II and IV would exhibit high heterosis for maximum good characters. A total of 350 alleles varied from 3(RM277) to 14(RM21) with an average of 7.8 per locus were detected at 45 microsatellite loci across the 31 rice accessions. The gene diversity ranged from 0.48 to 0.90 with an average of 0.77, and the polymorphism information content values from 0.44(RM133) to 0.89(RM206) with an average of 0.74. RM206, RM21, RM55, RM258 and RM433 were considered as the best markers on the basis of their higher polymorphism information content values. The dendrogram from unweighted pair-group method with arithmetic average clustering also classified the genotypes into four groups, where group IV comprised of 20 genotypes and group III of one genotype, but no duplicate was found. Finally, similar and duplicate named rice germplasms need to be conserved in gene bank as are distinct from each other.

A Review of the Study on the Electromigration and Power Electronics

引用

Journal of Electronics Cooling and Thermal Control 2016年第1期6卷 19-31页

作者： Md. Khalilur Rahman abul monsur Mohammed Musa Budrun Neher Kawchar Ahmed Patwary mohammad Atiqur Rahman Md. Shariful Islam Department of Physics Comilla University Comilla Bangladesh Department of Physics University of Chittagong Chittagong Bangladesh Department of Chemistry Comilla University Comilla Bangladesh Department of ICT Comilla University Comilla Bangladesh

Electromigration is a main challenge in the pursuit of power electronics, because physical limit to increase current density in power electronics is electromigration (EM), whereas much higher electrical current and voltage are required for power electronics packaging. So the effect of EM is an important issue in applications where high current densities are used, such as in microelectronics and related structures (e.g., Power ICs). Since the structure size of integrated circuits (ICs) decreases and the practical significance of this effect increases, the result is EM failure. On the other hand, in the next generation power electronics technology electrical current density is expected to exceed 107 A/cm2 which is another challenge. This review work has been carried out to identify the mechanism of EM damage in power electronics (e.g., pure metallization and solder joints) and also how to control this kind of damage.

Petrofacies Evolution of Bayana Basin Sandstones of Mesoproterozoic Delhi Supergroup, Bharatpur District, Rajasthan, Northwestern India

引用

Open Journal of Geology 2012年第4期2卷 260-270页

作者： abul Hasnat Masood Ahmad Chayanika Saikia Syed mohammad Wasim Department of Geology Aligarh Muslim University Aligarh India Directorate General of Hydrocarbons (DGH) Delhi India

The paper embodies results of petrofacies, detrital mineralogy and textural aspects of Bayana Basin sandstones of the Delhi Supergroup. These sandstones consisting of various types of quartz, feldspar, mica, rock fragments and heavy minerals are medium to fine grained and moderately well sorted. These sediments are generally subangular to subrounded with low sphericity. Various factors responsible for modification of the original detrital composition of the sandstones have been critically examined. Distance of transport is one of the factors which control the composition at the time of deposition. The plots of petrofacies in QtnFnL, QmnFnLt, QpnLvnLs and QmnPnK ternary diagrams suggest mainly basement uplift source (Craton interior) in a rifted continental margin basin setting, which has also received sediment input from recycled orogen provenance.
