铁路货车洗刷废水机械处理专题调查

本文从分析实验室试验、两级处理中机械设施以及包头东站机械设施的处理效果出发，得出货洗废水用机械设施处理效果好、去除率高，处理后水质基本能达标排放。若加强车辆洗刷前管理、彻底清扫，废水定能达标排放。     

波导升力矩对快速船在尾斜浪中横甩的影响

本文结合船舶操纵性和耐波性理论及其研究成果，引入一等效首摇角速度的概念表达环绕横甩中的船舶的波导南点速度，由此可以用静水中船舶操纵运动的水动力导数N′r估算波导升力矩。数值计算比较表明：波导升力矩与Froude-Krylov力短是属同一数量级。本文还讨论了横甩后的不稳定机理。     

P~(53)蛋白和PCNA在恶性纤维组织细胞瘤中的表达与预后的关系

为探讨恶性纤维组织细胞瘤（Ｍａｌｉｇｎａｎｔｆｉｂｒｏｕｓｈｉｓｔｉｏｃｙｔｏｍａ,ＭＦＨ）中Ｐ５３蛋白和增殖细胞核抗原（Ｐｒｏｌｉｆｅｒａｔｉｎｇｃｅｌｎｕｃｌｅａｒａｎｔｉｇｅｎ,ＰＣＮＡ）的表达强度与预后的关系,应用免疫组化ＬＳＡＢ法及彩色图像分析系统定量检测了４６例ＭＦＨ细胞中Ｐ５３蛋白和ＰＣＮＡ的表达强度。结果显示ＭＦＨ的Ｐ５３蛋白与ＰＣＮＡ表达间呈正相关,Ｐ５３蛋白阳性表达组ＰＣＮＡ的表达强度高于Ｐ５３蛋白阴性表达组（Ｐ＜０．０５）。Ｐ５３蛋白表达阳性和ＰＣＮＡ表达强度值高组较Ｐ５３表达阴性和ＰＣＮＡ表达强度值低组的生存期短、肿瘤转移率高、组织学分级高（Ｐ＜０．０５）;肿瘤位置深在组Ｐ５３蛋白和ＰＣＮＡ表达强度高于肿瘤位置浅表组（Ｐ＜０．０５）。结果提示定量检测ＭＦＨ的Ｐ５３蛋白和ＰＣＮＡ对于评估ＭＦＨ患者的预后具有较可靠的应用价值。     

Dynamic response of warship structure under air non-contact explosion

The ship hull is simplified as a free beam with varying sections. Based on hydroelasticity and explosion mechanics theory,mechanical model and kinetic equation for hull girder vibration under non-contact explosion are established. The equation is solved by Wilson-θ algorithm. On the basis of the above principles,a structure kinetics analysis program is compiled. The dynamic response of supposed warship under air explosion is calculated conveniently and quickly. Under the explosion condition designed in the paper,the positive pressure period of non-contact explosion wave is much less than the natural periods of the first four modes of hull girder and the resonance of ship girder overall vibration can be avoided. The ratio of midship maximum moment to ultimate bearing strength under non-contact explosion accelerates with the increment of impact factor.

Marine Biodiversity and Institutional Interplay

The interplay between the biodiversity regime and fisheries management and conservation regimes is not a critically important phenomenon at this point in time. For now, the institutions most relevant for the management of marine and coastal biodiversity are entrenched in conventional fisheries management structures. Biodiversity-oriented institutions appear to be less in touch with the practical aspects of resource management. The most significant interplay occurs at the global level, where several oceans-related regimes appear to be affected by the concerns raised by the CBD. The important question with regard to the longer term, is what impact the creation and operation of the CBD will have on various fisheries regimes in the future.

Estimating Recreation and Existence Values of Sea Otter Expansion in California Using Benefit Transfer

This article demonstrates how benefit transfer can quantify tourism and existence values. Existing literature values of sea otters and a meta analysis yield benefit estimates of several million dollars for the increased number of sea otters expected by USFWS in the next decade if the “no otter zone” is eliminated and otters allowed to expand along the Santa Barbara coast. These benefit estimates of sea otter expansion exceed the costs to commercial fishing. Thus the benefit transfer approach can contribute to a more complete economic analysis of endangered species recovery or critical habitat efforts than the current USFWS approach.
