A student in Shanghai Sanda University suddenly fell at tile basketball class at the end of last year. In the same month, a male student in Shanghai East China University fell on the ground when taking part in the physical test of lkm running, and then passed away after the rescue was not valid. In this paper, the physical quality of the current college students is discussed on the basis of studying college students＇ quality education. This study is expected to play a role in reference.展开更多

Certain foods with chemical additives disguised as food can cause muscle and joint pain associated with arthritis, gout, fibromyalgia, obesity, cancer and others. Avoiding these foods can reduced inflammation, thus prevent obesity, cancer, and another disease. The target of the study was to find a relation between food type, anthropometric parameters and obesity-related diseases for university students in CoUege-Al Leith-Umm al-Qura University, Saudi Arabia. The purpose is to identify populations （100 subjects women, aged： 17-30 year, using questionnaire） who are malnourished or at nutritional risk. Participants were divided into normal-weight and obese groups. The different methods are used to collect data including： 1. Anthropometric, 2. Dietary： Nutritional History （Current Intake）, 3. FFQ （Food frequency questionnaire）. There is a significant association between certain food type, anthropometric parameters, obesity as well as other diseases including （vitamin D deficiency, kidney problems, bone pain, general weakness, thyroid problems, infertility.展开更多

The best performance was obtained with a membrane composition of 10.0% （w/w） ion-pair, 45.0% DOP （w/w） and 45.0% PVC （w/w）. The electrode showed a Nemstian response （with a slope of 58.70 mV decade-1） for the concentration range of 4.2 × 10-5-1.0 ×10-2 mol/L. It illustrates a relatively fast response time in the whole concentration range （-15 s） in a pH range of 3.0-7.5. The selectivity coefficients were determined in relation to several inorganic and organic species. DAP is determined successfully in pure solutions and in biological fuids using the standard additions and petentiometric titrations methods.展开更多

A novel measurement method is demonstrated for optical zoom magnification measurement in this paper. The magnification is obtained by pattern correction between barcode image formed by optical zoom and reference image generated by an ideal optical model. Measurement accuracy which is better than 0.06% has been achieved for optical zoom magnification. Compared with traditional concept, the measurement results are only dependent on two line edges. The barcode correlation method can achieve higher accuracy and better robustness by using the information over the whole field of view.展开更多

The sensing surface was fabricated by self-assembly of an aptamer/mercaptohexanol monolayer on a gold disk electrode. The principle of this aptasensor is based on the competition between an adenosine target molecule and a ferrocene-conjugated signaling DNA strand for the aptamer binding site on the sensing surface. Due to the competitive nature of this assay,the electrochemical responses of the surface captured ferrocene are inversely proportional to log[adenosine] in the range from 0.05 to 3.2 μM,with a detection limit of 25 nM. Moreover,the aptasensor also shows high selectivity for adenosine. The proposed aptasensor thus holds great potential for the detection of other small biomolecules.展开更多
