A fishers’women-led Participatory Action Research(PAR)was conducted in 30 homestead ponds to assess the potential for polyculture of Tilapia(Oreochromis niloticus)and major carps Rohu(Labeo rohita)and Catla(Catla catla)in two coastal fishing villages of *** treatments,namely T1(Tilapia 200 fish per decimal;1 decimal=40 m^2),T2(Tilapia 200+Rohu 32+Catla 8 fish per decimal)and T3(Tilapia 200+Rohu 8+Catla 32 fish per decimal),each with 5 replicates,were tried in Hossainpur and Anipara *** commercial Mega-feed was applied to the ponds twice daily at an initial rate of 10%body weight(bw)/day of Tilapia down to 4%bw/day throughout the culture *** water quality parameters of ponds including transparency,salinity and dissolved oxygen significantly varied among treatments except temperature and pH and remained within optimum range for carp polyculture except *** survival rate,harvesting weight and yield of Tilapia were significantly highest in T1(85.63±05%,258.59±18.76 g&11073±805 kg/ha,respectively)in Anipara and lowest in T3(75.63±0.37%,136.97±10.63 g&5180±406 kg/ha,respectively)in *** gross fish production was the significantly highest in T1(11354±806 kg/ha)of Anipara and lowest in T1(6325±227 kg/ha)of ***,the highest net return(866,627±84874 BDT/ha)was found in T1 of Anipara and lowest in T3(279,389±46104 BDT/ha)of Hossainpur with a significantly higher benefit-cost ratio(BCR)obtained in T1(3.26±0.20)for Tilapia and lower in T3(1.58±0.10)for polyculture Tilapia and carp of ***,it may be concluded that Tilapia production in small homestead coastal ponds has a higher potential than its mix with carps in polyculture for generating food and supplemental income opportunity for coastal fishers’women in Bangladesh.

以某非对称双塔连体超高层结构为研究对象,选取与建筑所在场地相匹配的地震波作为激励,通过对结构进行非线性动力时程分析,研究混合消能减震连体结构在各烈度地震作用下的消能减震效果,探讨了屈曲约束支撑(buckling-restrained brace, BRB)与黏滞阻尼悬臂桁架的位置变化对结构抗震性能的影响,同时对结构进行了全面的抗震性能评估。研究结果表明:在连体结构中、上部的加强层中布设阻尼器时,结构具有更佳的减震效果;在不同水准地震作用下,BRB与黏滞阻尼悬臂桁架耗能阶段不同且具有不同的耗能效率,混合消能减震技术可以综合不同类型阻尼器的优势作用,使连体结构具有更全面的抗震性能。在控制变形方面,其能够降低连体结构的扭转效应和层间位移角;在构件耗能方面,其减轻了主体构件进入塑性的程度,降低了结构主要受力构件的应力水平。将为混合消能减震技术在连体超高层结构中的进一步研究和应用提供借鉴。
