In order to study drag reduction mechanism in mud parts’ operation of surface machine tools for paddy field, this paper takes floating plate, the main working part of laminating mechanism, as the research object and systematically analyzes the mechanism of action of elevation angle, curved angle, penetrating angle, and local microstructure of floating plate on working resistance and local fluid flow characteristics of the laminating structure based on VOF model in Fluent. Using ship mechanics theory and fluid lubrication theory, the drag reduction mechanism under different structural parameters of the floating plate is analyzed. The results show that, compared with the ordinary floating plate, the pressure difference resistance can be reduced by increasing the elevation angle by 60°, curved angle by 20°, and mud separation angle by 20°. The increase of the concave nonsmooth bottom surface structure can reduce viscous frictional resistance, and the total working resistance after structural optimization is comparatively reduced by 48.3%, with lowered hilling height in the forward direction and improved lubrication condition of the bottom surface, forming liquid lubrication effect. This study can provide theoretical references for the optimization design of muddy soil mud parts, mud-machine interaction research, and the development of paddy field laminating mechanism.

This Zhengyin a lot of little-known material, examines the many ancient Chinese scholars on whether the logic of the discussion, analysis of the two completely opposite answers lies the crux of their differences. Author Zhang Dong-sun more willing to recognize the logic of culture, and to ancient China to the logic of modern and contemporary research to do a comprehensive and profound reflection, and finally put forward the concept of equality more culture and adhere to the concept of large logic to present the ancient Chinese logical paradigm of contemporary conversion, thus the service goals of modernization of Chinese culture

This book presents an in-depth discussion on two concepts from the field of philosophy and law, in order to improve our understanding of the relation between “fact” and “evidence” in judicial process. Since fact-finding is a difficult task for judges, proof by evidence has been devised to help them access the truth. However, in the process of judicial fact-finding, there is always a gap between fact and truth. This book covers a wide range of topics, from reflections on the concept of “fact,” “evidence” and “fact-finding” in the field of philosophy and law to individual case studies. As such it is a useful reference resource on the continuing research on the judicial proof process for students and scholars.

Drawing upon the conservation of resources theory and social exchange theory, we examined the effects of family supportive supervisor behavior and family support on work absorption at the within- and between-person levels. A 10-day study of 91 workers using 710 observations was employed. At the within-person level, the results suggested that daily relaxation at work mediated the relationships between daily FS, daily shifts in FS, and daily work absorption. However, at the between-person level, the results revealed that chronic relaxation at work mediated the relation between the average level of FSSB/FS and chronic work absorption. We conclude that FSSB/FS plays a vital role in relaxation at work and work absorption at the within- and between-person levels.

We examine the impact of the African slave trade on corporate tax evasion in modern Africa. Using data from 28 African countries, we document that firms are more likely to evade taxes in countries that suffered a higher level of historical slave extraction. This finding is robust to an instrumental variable analysis. We further use household survey data to show that the slave trade has a long-lasting negative impact on tax compliance attitudes in the society and the quality of tax enforcement institutions. Our results highlight and quantify a pronounced historical determinant of cross-country differences in corporate decisions.

Philosophy and religion keep close connection by the intermediary belief of philosophers. The Greek philosophers criticized the object of masses’ and themselves religion depending on their rationality, finally gave up the masses’ belief and its object (religion). The Christian thinkers defended the masses’ religion and its object based upon philosophy and rationality. Modern philosophers appeared, going on with tradition of Greek philosophers, they reflected and criticized belief and its object, finally break away from masses ’ belief and its object and found themselves system of philosophy, and defended their belief and its object.In this way, philosophy broke away from traditional religion (Christianity). After the ancient philosophy of German, the philosophy is on the way of religion criticism; this phenomenon is related to the science directly. The philosophy which is not restricted by the religion could not help itself in the scientific world view. The philosophers who are swayed in the room between religion and science have not found their fairyland concerning the belief; as a result, their belief is thespian. The philosophy which could overcome the belief tragedy could be the other kind of philosophy. The western philosophy was searching for this new kind perpetually. This new kind of philosophy will emerge and boost in culture field.

Modern socialist economic reforms which center on the establishment of a commodity based economic system, demand a reconsideration of human nature. Marxism and human sociobiology give different answers to questions about human nature, but neither is complete in itself. It seems timely, therefore, to suggest that a combination of biological understanding with a Marxist-based social understanding would produce a more adequate notion of human nature, thereby helping us to resolve a number of problems posed by reforms currently taking place in socialist countries. We might also hope to face new challenges posed in the future.
