Treadmill speed was increased to a pace equivalent to 80% VO2max of the subject. A 4-wk washout period followed before the subjects crossed over and received the alternate supplement for the next 4 wk.They then completed a second exhaustive running exercise. The physiological variables that were examined included time to exhaustion and oxygen pulse. Moreover,the plasma creatine kinase (CK) and lactate were measured prior to the exercise, at 15 and 30 min during exercise,immediately after exercise, and 20, 40, 60, and 120 min after exercise.RESULTS: The major finding of this investigation was that the production plasma CK during the exercise significantly decreased for group AG than for group P. Secondary physiological finding was that 80% VO2max running was not improved over a 4-wk AG supplementation regimen.CONCLUSION: Supplementation with AG for 4 wk prior to an exhaustive aerobic treadmill running reduced the leakage of CK during exercise, but did not enhance aerobic work capacity. The reduction of plasma CK may be due to the fact that AG is effective for the decrease of skeletal muscle cell membrane damage, induced by exercise during the high-intensity treadmill run.展开更多

This law was passed after a multiyear study by national experts on what future nuclear technologies should be developed. As a result of the Act, the US Congress chose to develop the so-called Next-Generation Nuclear Plant, which was to be an HTGR designed to produce process heat for hydrogen production. Despite high hopes and expectations, the current status is that high temperature reactors have been relegated to completing research programs on advanced fuels, graphite and materials with no plans to build a demonstration plant as required by the US Con- gress in 2005. There are many reasons behind this diminution of HTGR development, including but not limited to insufficient government funding requirements for research, unrealistically high temperature requirements for the reactor, the delay in the need for a ＂hydrogen＂ economy, competition from light water small modular light water reactors, little utility interest in new technologies, very low natural gas prices in the US, and a challenging licensing process in the US for non-water reactors.展开更多

As members of team DRC-HUBO, we propose different approaches for the Rough-Terrain task, such as enlarged foot pedals and a transformation into quadruped walking. We also introduce a new gait for humanoid robot locomotion to improve stability performance, called the Ski-Type gait. We analyze the stability performance of this gait and use the stability margin to choose between two candidate step sequences, Crawl-1 and Crawl-2. Next, we perform a force/torque analysis for the redundant closedchain system in the Ski-Type gait, and determine the joint torques by minimizing the total energy consumption. Based on the stability and force/torque analysis, we design a cane length to support a feasible and stable Crawl-2 gait on the HUBO2 humanoid robot platform. Finally, we compare our experimental results with biped walking to validate the SkiType gait. We also present our team performance in the trials of the Robotics Challenge.展开更多

However, there are many problems in its professional teaching including incomplete dance types, inadequate teaching arrangement and insufficient artistic practice, which largely limited the development of dance major students and their comprehensive qualities based on dance expressive force. The article will discuss about the problems in dance education, and then put forward some targeted and available solutions.展开更多

Based on the successful experience of the American Black Fraternities, this paper further explores solutions to the serious problems existing in the Fellow Townsmen Association in Chinese universities to make it the same valuable asset for the development of the members＇ personality and comprehensive quality. The Association should be leveled up to an official student society to solve many of its managerial problems, and set a group goal to direct its members to the right track of serious study and completely transform the form and the content of its activities to improve the social skills of its members.展开更多

The reform of aerobics teaching in colleges and universities should be geared to the demands of the times, and explore new innovation and continual development. In this paper, using the research methods of documentation, courseware development, teaching experiment and mathematical statistics, we study on the making and application of college aerobics network teaching courseware. It is revealed that, with the combination of modem network technology and college aerobics teaching, the resulted college aerobics network teaching courseware is the important media to not only upgrades college aerobics teaching quality, but also help develop students＇ habits of doing physical exercise, and promote physical health. Therefore, this is meaningful and practical in promoting the education of college students in physical quality development.展开更多

Their primary goal has functionality and efficiency rather than aesthetic considerations and, yet from a time perspective, they still impress with their beauty and perfection. Gradually, architects began to take care of the form of bridges, as in the case of the Rialto Bridge in Venice. Nowadays, the most renowned architects, with Norman Foster in the lead, take up the design of bridge ＂architecture＂. Although technical solutions remain top priority, aesthetic qualities are widely recognized and appreciated.展开更多

It is supposed that before the Permian period the Armenian-lranian Mezocontinent was uniform with Afro-Arabia and only at the end of the late Paleozoic the formed Mesozoic ocean separated these areas from each other. A result of application of the complex laboratory investigations were identified from samples of primary magnetization the direction of which corresponds to the time of formation of the studied rocks. On the basis of paleomagnetic researches of Triassic, Permian, Devonian, Carbonian rocks a preliminary conclusion has been made about the dipole configuration of the geomagnetic field throughout Paleozoic. The comparison of the obtained data to paleomagnetic definitions of African, Arabian plates, Europe and the Siberian platform leads to the conclusion that the Minor Caucasus existed separately from the present general lithosphere blocks of Greater Caucasus and Europe.展开更多
