Sixteen urban soils with a wide range of total P concentrations under typical urban land uses were sampled and analyzed for extractable P concentrations using water, sodium bicarbonate and citric acid. Meanwhile the soils were artificially leached in columns and P concentrations in the leachates were determined. With linear regression a two-stage linear relationship was found to exist between concentrations of P in the leachates …展开更多

METHODS： Sixty-one patients （37 males, aged 17-74 years） with anal fistulae, which were not simple low types, were evaluated by physical examination and 3D-EAUS with and without enhancement. Fistula classification was determined with each modality and compared to operative findings as the reference standard. RESULTS： The accuracy of 3D-EAUS was significantly higher than that of physical examination in detecting the primary tract （84.4% vs 68.7%, P = 0.037） and secondary extension （81.8% vs 62.1%, P = 0.01） and localizing the internal opening （84.2% vs 59.7%, P = 0.004）. A contrast study with H202 detected several more fistula components including two primary suprasphincteric fistula tracks and one supralevator secondary extension, which were not detected on non-contrast study. However, there was no significant difference in accuracy between 3D-EAUS and H202- enhanced 3D-EAUS with respect to classification of the primary tract （84.4% vs 89.1%, P = 0.435） or secondary extension （81.8% vs 86.4%, P = 0.435） or localization of the internal opening （84.2% vs 89.5%, P = 0.406）. CONCLUSION： 3D-EAUS was highly reliable in the diagnosis of an anal fistula. H2O2 enhancement was helpful at times and selective use in difficult cases may be economical and reliable.展开更多

Based on the Chinese national standardization status, this paper sets an evaluation system of national standardization on the principles of logic, comprehensiveness and operability, taking into account national standards and standardization activities. The evaluation system evaluates the national standardization development level through four aspects： standard development, standards implementation, standardization supporting measures, and participation in international standardization. This evaluation system provides a reasonable basis to evaluate the national standardization development level. The survey shows that if China wants to enhance its standardization development level, China needs to improve its standard development level, strengthen implication and application of standards, expand the standardization support measures and continuously improve the level of participation in international standardization.展开更多

This paper summarizes the international situation and progress, and analyzes the international development tendency of carbon emission management standardization. Correspondingly, the national situation and progress of carbon emission management standardization is reviewed including involvement of international standardization, establishment of national standardization committee, development of national standards and so on. And the policy suggestions are raised to strengthen the standardization work in the fields of addressing climate change during the 12 th Five-Year Plan period.展开更多

Standardization and low-carbon economy interact with each other and develop together in the principle of continuous improvement and spiral progress. They embed the social development system in a flexible mode of technical penetration, and become the important links in the industrialization chain of technical innovation. Standardization promotes the low-carbon economic development in seven aspects including ＂systematic coordination and overall promotion＂, ＂technical accumulation and innovative diffusion＂, ＂quality improvement and waste reduction＂, ＂continuous improvement and spiral progress＂, ＂barrier elimination and cooperation enhancement＂, ＂technical support for market mechanism＂ and ＂local standards and regional emission reduction＂, etc. This paper is a periodical research achievement of Two-oriented Society.展开更多

The enterprise implementing the standardization is capable of flexible responding to customer＇s demands for the assortment, accelerates considerably research, and offers satisfactory delivery terms. That means the selection of types of the input factors and the method how to use them, the selection of working procedures and procedures of intermediary consumption, definition of the relations in the process of control, rational structure of the final products etc..

In America, college student pay attention to NCAA （National Collegiate Athletic Association）, there are many famous coaches in it, such as Nich Saban, Jerry Tarkanian, and more. The authors are very interested in the competitive life of those who are the top five coaches in the world. So the authors concentrate on the winning rate, the contribution rate, and the cycle of the honors to evaluate each coach, by standardizing the metrics, they get the final scores of each metric for basketball; according to the scores, they get the top five coaches in a century. And in this paper, the authors also take the gender and timeline into account.展开更多
