Wave scattering by undulating bed topography in a two-layer ocean

The problem of wave scattering by undulating bed topography in a two-layer ocean is investigated on the basis of linear theory. In a two-layer fluid with the upper layer having a free surface, there exist two modes of waves propagating at both the free surface of the upper layer and the interface between the two layers. Due to a wave train of a particular mode incident on an obstacle which is bottom-standing on the lower layer, reflected and transmitted waves of both modes are created by the obstacle. For small undulations on the bottom of the lower layer, a perturbation method is employed to obtain first-order reflection and transmission coefficients of both modes for incident wave trains of again both modes in terms of integrals involving the bed-shape fimction. For sinusoidal undulations, numerical results are presented graphically to illustrate the energy transfer between the waves of different modes by the undulating bed.

The impact of thinking differences between English and Chinese on translation

Translation is not only a language activity, but also a thinking activity, which involves the conversion of the two languages, and the language is both a thinking tool and the result of thinking. Language and thought are closely related, and they are both interacting and interdependent. Different thinking determines that the expression of both English and Chinese on the same topic is also different. Through the relationship between language and thought, standing on a higher philosophical point of thinking, we can investigate the effect of the differences between English and Chinese translation. The translator can pay more attention to the difference＇ s impact of translation, which assure a higher accuracy of the translation.

The Tactical Mind in Soccer： The Habit of the Brazilian Squad in the 1970＇s World Cup

This work aims at understanding the tactical action of soccer players from the point of view of Peirce＇s pragmatism. We will focus on the maxim of pragmatism, in which the elements of every concept enter into logical thinking through the doors of perception and leave through the doors of utilitarian actions. In this paper, we investigate the formation of a habit able to manage collective actions on a soccer field. The efficiency of this habit is related to collateral experience shared among soccer players： characteristics of high performance sports training. This unique experience orchestrates perceptions and reasoning, leading to efficient combination of conclusions and influences collective actions. We will analyze the concept that we call avalanche in bow-arrow applied to the 1970＇s Brazilian soccer team.

The objective of this research was to enhance adsorption capacity of Acacia nilotica （keekar） sawdust for the abatement of chromium bearing wastewater and to investigate the effect of process parameters on adsorption capacity. The sawdust was activated by acid wash and functionalized subsequently with formaldehyde. Functionalization of activated sawdust raised its chromium removal efficiency of almost 10% as compared to its adsorption removal efficiency of HCl treated sawdust in a batch adsorption study. Adsorption kinetic data provided better fitting with pseudo second order model. Maximum adsorption capacity calculated through the best fitting Langmuir model was 6.34 mg·g^-1 and 8.2 mg·g^-1 for HCl treated and formaldehyde functionalized sawdust adsorbents, respectively. The adsorption of Cr（VI） was endothermic when studied by varying temperature from 20℃ to 50℃ for both activated and functionalized adsorbents.

The Intemal Implication of the Economic Ethics in the Alienated Labor Theory of Economic and Philosophical Manuscripts of 1844

Alienated labor, also known as labor alienation, was a concept with historical creativity, which was first raised in Marx＇ s Economic and Philosophical Manuscripts of 1844. The Manuscripts was important works of Marx, in which the social relations of capitalism private ownership were analyzed by Marx using the concept of alienated labor. A deep analysis was conducted by Marx from the specific historical facts, in which the rational kernel of the alienated problem in the social relations of capitalism was mentioned. Specifically, the alienated labor theory was analyzed from the relationship of laborers with their labor products and labor itself, human＇ s essence, and other people under the condition of the capitalist private ownership; the ＂ought to be＂ ethical characteristics of labors were expounded from the perspective of ethics, and the abnormal labor relations in the process of capitalist production were ethically reviewed and criticized. Therefore, rich economic ethics thoughts were contained in Marx＇ s analysis of the alienated labor theory.

A Reflection of Minimum Adequate Education in South Carolina More Than Fifty Years Later

The issues and challenges of minimum adequate public school education in the State of South of South Carolina has been a struggle between lawmakers and taxpayers for more than fifty years. The enactment of the Civil Rights Act of 1964 led to forced school integration, busing, and led to whites＇ physical moving out of selected school districts. Selected public schools filed a lawsuit against the State of South Carolina to the Supreme Court with the claim of failing to provide adequate and equal education to all children in the state. This reflection focuses on the Abbeville case in context, funding issues, and inadequate facilities, which concludes with a reflective view of the Brown v. The Board of Edueation 1954 decision.
