Large size utility boilers develop rapidly in China, both their reliability and economics have reached better level. The operating situations of various existing boilers on the basis of different coals are analyzed, it is held that, the notable energy imbalance of furnace exit, ever existing in the tangential firing boilers has been solved, with comparatively lower NOX emission concentration of gained. The higher NOX emission concentration and furnace slagging etc. problems existing in wall firing boilers are notable. The comprehensive analysis shows that, it is appropriate to choose lower furnace volume heat release rate and higher flame height in the type selection design of boilers, and sufficient margin should be kept in the selection of coal pulverizing mills. 展开更多

Purpose: The relationship between acute exercise and executive functions in college students with attention deficit hyperactivity disorder (ADHD) has not been clearly established. The purpose of this preliminary study was to examine the difference in cognitive performance between college students with and without ADHD and to explore the effects of acute exercise on multiple aspects of executive functions and on serum brain derived neurotrophic factor (BDNF). Methods: College students (normal: n = 10; ADHD: n = 10) performed the Stroop Test, Trail Making Test, and Digit Span Test prior to and after an acute exercise intervention. Blood samples were obtained prior to the pre-test cognitive test performance and then again after exercise and prior to the post-test cognitive test performance. Results: Students with ADHD exhibited impaired executive functions, particularly on inhibition. Additionally, while acute exercise improved all aspects of executive functions in those without ADHD, acute exercise only improved inhibitory performance for those with ADHD. Further, BDNF was not influenced by acute exercise regardless of the subjects' ADHD status. Conclusion: These results provide preliminary evidence for exercise as a potential adjunct treatment for benefitting inhibition in college students with ADHD. 展开更多

A difficult problem for the system construction of the modem university is the issue how the academic power and the ad- ministrative power can coordinate and orderly operate. The weakening of the academic power and the strengthening of the administrative power make the university slope foot forward in the development. To solve this problem, first of all, we should restore the originality of the academic power and the academic tissues. By perfecting the sla'uctures and functions of the university organizations, improve the control on the power, and make the power operate in its due orbit, to ensure that the modem university system is not a mere formality. 展开更多

Performance art in every region and country depends mainly on rules, customs, and beliefs of that particular society hence; this art enjoys diversity with respect to its forms and contents. In contemporary lran, with the emergence of new artistic movements, performance art incorporated more academic and enlighten aspects. New mass media and modern visual medium such as light, sound, moving, and changing images, video displays as well as application of new signs and symbols are some of the special characteristics of the contemporary performance art in Iran. Moreover, the performance art in Iran is not merely related to the contemporary era rather it encompasses a large number of traditional representations that have been prevalent among common people with much meaningful rules. Its popularity among common people is also a conceptual art which conveys a content-based meaning in a more dramatic sense. For centuries, the tradition of performance art in Iran can be observed in the rules of Ta'aziehkhani (quite singing or passion play), Shamayelgardani (icon handling), Ru-howzi (performance on pool platform), Marekegiri (mono drama), Qhashoqhzani (spoon handling) and Aroosakgardani (puppet handling). Aestheticism relying on traditional performing method is also the outcome of taste and elegance of common people. These performances have more folkloric aspects protruding from humane institutions and blended with their vernacular beliefs. In the traditional method of performance art, performers mostly enjoy their own taste and style and use handy means for executing their roles. In contemporary Iran, traditional method along with modern theme has been widespread among people particularly in villages and small townships although these are not called as art. The present study is an attempt to study existing challenges to modern and ancient art traditions as well as aesthetic values attributed to each of them. 展开更多

This paper examines the recent current of nationalism in China's Mainland. It takes not only nationalist intellectual texts written by Wang Xiaodong and other "Say-no Club" members into critical scrutiny, but also nationalistic sentiments frequently appeared on the Chinese web and streets since the late 1990s. The findings of the analyses proffered by this paper are expected to enhance not only the understanding of today's China and Chinese nationalism as a localized and "embedded" discourse/phenomenon, but also, hopefully, that of nationalism and its generative and operational mechanism in general--nationalism is an "obscene discourse" and operates in the fantastic ground while producing real violence. 展开更多

Cooling energy needs, for mines in Northern Ontario, are mainly driven by the mining cooling technologies available and the cost to implement them in a 2500 m deep underground mine. The cooling technologies reviewed herein include mechanical and natural cooling systems, ranging from mechanical chillers to seasonal thermal storages. The economic and operating parameters for each technology were estimated and evaluated according to the mine's energy loads. Including consideration of any combined heat and power benefits of the technology, cooling tower requirements, etc., the resulting cost of implementation for each technology could be ranked. This showed that the natural thermal storage systems and conventional chillers were the most cost-effective, mainly since the natural systems had very low operating cost and the chillers had relatively low capital costs. 展开更多

An optimal design of wastewater reuse for a University is concerned in this paper. The raw water and the capacity of wastewater reuse were determined according to the wastewater characteristic of a university; the treatment process was chosen by building a cost-benefit model; and the modeling test was performed about the operation effect of the proposed project and the recommended water quality of reclaimed water. It is estimated that 3.4×10^5 m^3/a tap water and 6.1×10^5 Yuan/a will be saved if the project was put into operation and the proposed project will reduce the total quantity of pollutant efficiently and bring lots of social and economic benefits. 展开更多
