Heavy metal contamination of the g.oundwater of south West Bank in Palestine was assessed. The g.oundwater samples were analyzed for different trace heavy metals (Tl, Pb, Bi, Cr, Mn, Co, Ni, Cu, Zn, Mo, Ag. and Cd), and al content by ICP/MS. This study was conducted to determine the water quality of g.ound water which is used for drinking.in the study area. Water samples from ten g.oundwater wells were obtained in four different dates of the year (October 2012, November 2012, March 2013, and April 2013). Three water samples were obtained from each well for each sampling.date. A total of 120 water samples were collected from the ten wells. The samples were analyzed for their pH, electrical conductivity, total dissolved solids, and different trace metals content. The pH, electrical conductivity, and total dissolved solids of all water samples were found to be within the US Environmental protection Ag.ncy limits. Results showed that Pb, al, Cr, Co, Ni, Cu, Zn, and Mo were detected in all water samples analyzed in this study, while Tl, Bi, Mn, Ag. and Cd were detected in 80%, 88%, 90%, 75%, and 95% of the water samples analyzed in this study, respectively. In g.neral, 93% of all samples analyzed contained one or more of the 13 metals studied each in varying.concentration. Furthermore, results showed that the concentration of Cr, Mn, Ni, Cu, Zn, and Mo is within the allowed WHO limits in drinking.water. However the concentration of Pb Cd, and al are found to be hig.er than the allowed WHO limits in 40%, 8%, and 33% of the water samples analyzed in this study, respectively. Statistical analyses showed that concentrations of the metals studied in this study vary sig.ificantly between the ten g.ound water wells, indicating.that the wells analyzed in this study is different from each other in terms of heavy metal content. Additionally, from the statistical results obtained, it was found that there is a sig.ificant difference in the concentration of the metals in each well fo

人们指望发展理论解答以下3个问题:“为什么我们这么富,而南半球国家却那样穷?”“如何解释南半球国家的生产增长率和福利的不同?”“面对这些问题,我们应该怎么办?应当采用什么样的战略?”如果把强调生产因素的发展论和所谓的依附论排除在外,发展理论几乎没有解答第一个问题。另外,我们发现第三个问题同第二个问题并没有必然的联系。也就是说,第二个问题属于历史问题,第三个问题则针对的是未来。

这一新著对分析哲学的批判给人启发;其主要针对四个代表人物——罗素、维特根斯坦、卡尔纳普和奎因。在王氏看来,“超越”分析哲学,便是抛弃关于我们如何认识的经验论者观点及能够认识什么这一问题上的认识论局限。分析的经验论把科学基础作为“合理”哲学的中心,却遮阻了重要的全球性视野,(比如)可在欧陆和东方哲学中发现这一视野。王氏提出了康德式的先验辩证法:如果我们要公正看待知识的诸多领域,既包括科学知识(数学和物理知识),也包括艺术、诗歌、情感和伦理的知识,那么要求怎样的解释?其观点是,“直觉”

Journal of Oceanolog. and Limnolog. 2018年第5期36卷 1860-1869页

Kuwait's shrimp fishery presents typical tropical shrimp fishery characteristics with hig.ly variable recruitment, fast g.owth and strong.seasonal patterns. Both the g.neral Production Model and Ag.-structured Model were chosen to assess the stock status of the Kuwait's shrimp fishery. The estimated Maximum Sustainable Yield(MSY) was 2 518 metric ton(t) with a corresponding.fishing.eff orts( f MSY) 7 265 standard boat-days from the g.neral Production Model. Similar results from the Ag.-structured Model were 1 936 t and 6 449 boat-days respectively. Comparing.these results with the averag. annual shrimp landing.(1 772 t) and averag. fishing.eff ort(9 710 boat-days) in the past 10 years, we concluded that the fishery was overfished. Model simulations to show the chang.s of recruitment, biomass and possible catch under different fishing.eff ort scenarios indicated possible stock collapse if the fishing.eff ort continually increase. But both shrimp recruitment and biomass will increase if the current fishing.eff ort is reduced. Model simulations also showed a possible increase of MSY by delaying.the opening.or by closing.the season earlier. Based on these results, recommendations to improve the manag.ment of Kuwait's shrimp fishery are presented.
