This research article is based on the biodiesel synthesis from the marine green macroalga Ulva fasciata, collected from the coast of Karachi, Pakistan using new and the most potential waste catalysts from Pakistan Steel *** oil was extracted with n-hexane then it was analyzed by GC, TLC and by the examination of fuel *** metal analysis of catalysts was carried out by chemical tests and flame atomic absorption spectroscopy(FAAS). The thermal treatment of catalysts at 1500–1700 °C during various processes in steel manufacturing industry converted the metals to metal oxides. The presence of CaO, MgO and ZnO in these catalysts made them highly reactive for biodiesel synthesis. The basicity of waste industrial catalysts was calculated to know their basic strength. The transesterification of U. fasciata oil was performed by fast stirring using 9:1 molar ratio of methanol/oil in the presence of seven different waste industrial catalysts for 6 h at 80–100 °C. The solid catalysts were easily separated from product for re-use. In addition, the rate of reaction in the presence of these catalysts was found to be quite feasible. The waste brown dust from the steel converter gave the highest yield(88%) of biodiesel. The production of biodiesel was confirmed by TLC examination and fuel properties in comparison with the ASTM standards.

This study records length-weight relationships （LWRs） for eleven commercially important marine catfish species of the family Ariidae （sea catfishes） and Plotosidae （eel catfishes） from the northern Arabian Sea coast of Pakistan. The specimens were sampled from December 2014 to November 2015, using bottom trawls with various mesh sizes by commercial vessels. The species were Nemapteryx caelatus, Sciades sona, Arius gagora, Batrachocephalus mino, Neturna thalassina, N. bilineata, Osteogeneiosus militaris, Plicofollis dussumieri, P. tenuispinis, Plotosus limbatus, and P. lineatus. Of the eleven species, two species A. gagora and N. bilineata were recorded for the first time and LWRs for four species A. gagora, N. bilineata, S. sona, and B. mino still have no data in the FishBase database. In addition, new maximum length for each of the three species N. bilineata, O. militaris andB. mino was also found.

研究目的:本文以巴基斯坦女性运动员为研究对象,旨在分析女性运动员的日常体力活动与心理健康水平之间的相关关系,以及影响上述两项指标的潜在因素。研究方法:采用国际体力活动量表(短篇)作为评价工具,来统计巴基斯坦女性运动员的日常体力活动情况。采用沃里克-爱丁堡积极心理健康量表,来统计受试者的心理健康水平。本研究共发放问卷221份,回访210份,排除异常值27份,无效问卷183份。采用单因素方差分析法,考察不同年龄、运动项目、运动年限、运动等级、教育程度以及经济状况等因素,对女性运动员的日常体力活动和心理健康水平的影响。采用皮尔森相关法,分析日常体力活动与心理健康水平之间的相关关系。研究结果:运动计划(P=0.029)、运动水平(0.004)和社会地位(0.034)这三个自变量将显著影响女性运动的日常体力活动。其中,女运动员在曲棍球运动中的日体力活动得分(IPAQ=6667.5)明显高于其他运动的运动员。区级运动员的日体力活动得分(IPAQ=6964.1)明显高于其他运动。经济条件相对富裕的女运动员的日体力活动得分(IPAQ=5900.6)显著高于普通和贫困家庭的女运动员。年龄和经济状况是影响巴基斯坦女运动员心理健康的主要因素。其中,30～33岁女运动员心理健康评分显著高于其他年龄组(P=0.005)。经济富裕的女运动员的心理健康得分也明显高于其他女性(P=0.004)。IPAQ评分与心理健康评分之间存在显著的正线性相关性(P=0.000)。研究结论:巴基斯坦女运动员的特点是年龄结构年轻,受教育程度较高。体育项目,比赛水平和经济条件是主导巴基斯坦女运动员日常体育活动的主要因素。年龄和年龄是主导巴基斯坦女运动员心理健康分数的主要因素。对于巴基斯坦女运动员来说,日常身体活动与心理健康之间存在正相关关系。适当增加日常身体活动,将促进他们心理健康的健康发展。
