Hydrodynamic coefficients of a simplified floating system of gravity cage in waves

Numerical simulation and experimental tests were carried out to examine the hydrodynamic behaviors of a double-column floating system of gravity cage under wave conditions. A floating system of gravity cage can be treated as a small-sized floating structure when compared with the wavelengths. The main problem in calculating the wave loads on the small-sized floating structure is to obtain the reasonable force coefficients, which may differ from a submerged structure. In this paper, the floating system of gravity cage is simplified to a 2D problem, where the floating system is set symmetrically under wave conditions. The motion equations were deduced under wave conditions and a specific method was proposed to resolve the problem of wave forces acting on a small-sized floating system of gravity cage at water surface. Results of the numerical method were compared with those from model tests and the hydrodynamic coefficients Cn and Cr were studied. It is found that Cn ranges from 0.6 to 1.0 while Cr is between 0.4 and 0.6 in this study. The results are useful for research on the hydrodynamic behavior of the deep-water gravity sea cages.     

Potential natural exposure of endangered red-crowned crane (<Emphasis Type="Italic">Grus japonensis</Emphasis>) to mycotoxins aflatoxin B<Subscript>1</Subscript>, deoxynivalenol,zearalenone, T-2 toxin,and ochratoxin A

A survey was conducted to determine whether mycotoxins were present in the foods consumed by red-crowned cranes (Grus japonensis) in the Yancheng Biosphere Reserve, China. Collected in the reserve’s core, buffer, and experimental zones during overwintering periods of 2013 to 2015, a total of 113 food samples were analyzed for aflatoxin B₁, deoxynivalenol, zearalenone, T-2 toxin, and ochratoxin A using high performance liquid chromatography (HPLC). The contamination incidences vary among different zones and the mycotoxins levels of different food samples also presented disparity. Average mycotoxin concentration from rice grain was greater than that from other food types. Among mycotoxin-positive samples, 59.3% were simultaneously contaminated with more than one toxin. This study demonstrated for the first time that red-crowned cranes were exposed to mycotoxins in the Yancheng Biosphere Reserve and suggested that artificial wetlands could not be considered good habitats for the birds in this reserve, especially rice fields.

林语堂译《浮生六记》的"传神"美

文学翻译重在传递原文的“形”和“神”,以做到形神兼备为最佳,也即在正确表达原文意思的基础上传达弦外之音,这也正是翻译中最大的一个难题。翻译家和文学家林语堂先生所译沈复的《浮生六记》就很好地做到了形似和神似的统一,无论是从语言的选择、篇章的理解到情感的再现和意境的重铸都译得丝丝入扣,完整地再现了原文的神韵。本文欲从“传神”的角度分析林先生所译《浮生六记》所体现出的美。     

流动人口对新疆社会经济的积极作用

大量流动人口来到新疆,冲破了地域、民族的界限,扩大了各民族交往的范围和领域,推动了新疆社会经济的发展。流动人口带来了新的信息和技术,改变了新疆本地的传统观念,对新疆民族文化的传播和发展也起到了一定的积极作用。人口流动促进了各地不同民族间的接触交流,改变了人们狭隘的地域观念。通过人口的流动,不同民族间的社会交往增加、经济联系加强,同时也促进了民族间的文化认同和变迁。

林语堂与《浮生六记》中的陈芸

文化是一种经过长期历史积淀所形成的心理定式,这种定式一旦形成便成为一种集体无意识,会像基因一样遗传延续下去,在一代又一代人的身上或族群中显现出来.追求个人自由,崇尚自适自慰的道家文化,对中国历代文人的心理定式作用绵延不断,如嵇康、阮籍、陶渊明、李白、苏轼、沈复、林语堂等都受到一定的影响,对他们的性情及心态都产生过不同程度的文化塑形功效.因此分析<浮生六记>作者的爱人陈芸的生活方式,我们可以从侧面了解到林语堂的生活情趣与人生态度,了解到中国文化对知识分子人格形成的影响.
