The study was conducted to estimate the post-harvest loss(PHL)of inland capture fisheries in Bangladesh based on the fishing venture i.e.,sole proprietorship,partnership and cooperatives using Questionnaire Loss Assessment Method(QLAM).A total of 1339 fishermen were selected using stratified random sampling where 792,485,and 62 were involved in the sole proprietorship,partnership,and cooperatives types of fishing venture *** data were collected from thirty-nine districts across six divisions through the direct interview method covering 92 fish *** results indicated that Ashar(June-July)to Agrahayon(November-December)was the peak fishing period for every fishing *** study revealed that the high volumes of fishes were caught from haor for partnership and cooperatives while river was for sole *** study accounted lower PHL for cooperatives than that of sole proprietorship and partnership and found significance differences among them from Tukey’s pairwise *** estimated PHL was higher for Puti(Puntius chola)in sole proprietorship and partnership whereas Tengra(Gagata cenia)in cooperatives *** study suggests to expand the cooperatives fishing ventures widely in Bangladesh where the predominant factors(i.e.,longer harvesting duration,delaying in marketing the fishes and temperature,excess supply,and etc.)of causing PHL in this venture should be taken under consideration.

Design and Comparative Analysis of Small Modular Reactors for Nuclear Marine Propulsion of a Ship

引用

World Journal of Nuclear Science and Technology 2018年第3期8卷 136-145页

作者： Monirul Hoque A. Z. M. salauddin md. Reaz Hasan Khondoker Department of Nuclear Science and Engineering Military Institute of Science and Technology Dhaka Bangladesh Department of Naval Architecture & Marine Engineering Military Institute of Science & Technology Dhaka Bangladesh

The fast growth in the size and difficulty of nuclear power plant in the 1970s produced an interest in smaller, modest designs that are intrinsically safe over the usage of design features. With the development of nuclear technology, there is the need for revolution in the Maritime sector, especially the advance marine propulsion. In current years, numerous reactor manufacturers are dynamically improving small modular reactor designs with even superior use of safety features. Several designs integrate the ultimate in greater safety. They totally remove specific accident initiators from the design. Other design features benefit to reduce different types of accident or help to mitigate the accident’s consequences. Although some safety features are mutual to maximum SMR designs, irrespective of the coolant technology, other features are specific to liquid-metal cooled, water, gas, or SMR designs. Results: There have been more reactor concepts investigated in the marine propulsion area by different assemblies and research laboratories than in the power generation field, and much can be learned from their experience for land applications. The extensive use of safety features in SMRs potential to make these power plants extremely vigorous, protecting both the public and the investor. Conclusion: For these two considerations, it is recognized that a nuclear reactor is the ideal engine for naval advanced propulsion. The paper will present the work to analyze the concept design of SMRs and design a modular vessel consisting of a propulsion module.
