Relied on trusted computing technology, a privilege separation method is proposed to satisfy the security management requirement for information systems. It authorizes the system privilege to three different managers, and none of it can be interfered by others. Process algebra Communication Sequential Processes is used to model the three powers mechanism, and safety effect is analyzed and compared.展开更多

A greenhouse study was conducted to examine the effects of four N rates on the competitive ability ofEchinochloa colona and Amaranthus viridis grown together with direct-seeded rice. Rice and each weed species were grown in a replacement series design at added N rates of 0, 50, 100, and 150 kg ha1. Replacement series diagrams for relative yield showed that competitive ability ofE. colona increased with added soil N. Values of weed aggressivity index for E. colona also significantly increased with the addition of N in the soil. In the absence of added N, A. viridis was more competitive than rice but this relationship slightly changed as N was added. However, values of weed aggressivity index of were statistically similar at all N rates. The results suggest that the competitiveness ofE. colona increased with added soil N, and A. viridis unchanged by soil N levels. Both weed species were different in their response to higher N levels. Information gained in this study could be used to demonstrate the importance of effective weed and fertilizer management.展开更多

This stage marked by facts and characteristics based on search for information, explore the students world, and their expectations for that science. This study is the first in its kind in United Arab Emirates that try to shed light on the social and psychological effects of the lnternet, therefore we pave the way in front of those who administer lnternet and indicate to them guidelines for that to allow decisions maker to be aware about the world around university's student, the world that enjoy less interest for use of Internet at university, and what is the social and psychological effects of the use of Internet. And the study allow providing information and data that several sectors in society need. It draws clear image for the use of Internet at university by the student and whatever social and psychological effects that happened as a result of that use, so it consider as a survey for whom desire to know such information in United Arab Emirates.展开更多

A successful tea packing design can affect the consumers' desire to buy. In this article, from the tea packaging colors, forms, shapes and so on, the author discusses the vision, touch, taste and other sensory stimulation, and analyzes the relationship between the constituent elements including the emotional factors and the psychological needs of the consumers, as well as the packaging design.展开更多

Reactions to increased inequality in China, as elsewhere, have treated inequality as a pathology when in fact it is more usual than equality, and possibly more functional in terms of social and individual development. The problem with inequality is not that it exists but that it may be poorly conceived, especially in public discourse, and consequently that it is inadequately managed. Inequality extends well beyond questions of income and wealth to the distribution of power, of gender and of generation. Healthy societies require more even wealth distribution but they also require a wider appreciation of different types of inequality.展开更多
