Abbas A. Essa  Ke-xi Xu  Shi-ping Zhou  Jia-shan Bao 《上海大学学报(英文版)》2000,4(2):116-118

YBa₂Cu₃O_7-734; weak link junctions with width from 0.1 mm to 0.3 mm and length from 0.2 mm to 0.5 mm was made by hand with a razor blade. The current voltage characteristics of the microbridges show, under microwave irradiation, pronounced Shapiro steps up to transition temperature. A careful measurement of the dependence of the critical supercurrent on the external magnetic field and laser light is presented.  相似文献   

U6-7阶段运动技能分层教学实验研究——构建基本动作技术最低程度自动化筛查标准     

王兴泽 《赣南师范学院学报》2014,(6):84-88

运用文献资料、实验验证和教学、数理统计等方法,针对U6-7阶段构建基本动作技术最低程度自动化筛查标准并进行检验验证,同时采用该标准进行实验教学试验研究.得出通过该筛查标准进行分层教学效果明显高于传统行政班级教学效果,且符合现代基础教育改革中小学课程整合的教学理念.本文构建的基本动作技术最低程度自动化筛查标准是现代运动技能动作学习教学的底线,本标准提供于小学体育教学一线实践和为政府职能部门提供参考.  相似文献   

我国公立高等学校法人制度的问题及其改革     

罗爽 《复旦教育论坛》2014,12(5):58-63

高等学校法人制度以高等学校的基本组织属性为价值基础,应当是一项契合高等学校自主性和公共性的法律制度,其内部价值冲突的整合模式包括自主性本位、公共性本位以及自主性和公共性冲突整合三种。我国高等学校法人制度在价值基础方面选择了自主性本位整合模式,并呈现出市场自主性的偏向。其问题表现为:缺乏高等学校自主运转的必要保障机制安排,导致保障高等学校自主性的制度目标未能达成;忽视高等学校的公共机构身份,导致高等学校公共性危机的产生。对其进行改革的应然选择是建立第三部门视野下的高等学校法人制度。  相似文献   

Angiogenic Potential,Circulating Angiogenic Factors and Insulin Resistance in Subjects with Obesity

Altered vascular function and pathological angiogenesis are important factors common to the development of obesity and obesity-associated diseases. Most human studies relating obesity and angiogenesis have compared levels of angiogenic factors in obesity without looking at the serum angiogenic capacity which reflects the balance between the effects of angiogenic and angiostatic factors. Therefore, in this cross-sectional study, the serum angiogenic potential and levels of angiogenic factors in serum of obese (BMI > 25 kg/m²) and lean subjects (BMI < 23 kg/m²), with no history of obesity associated co-morbidities, were assessed. Serum angiogenic potential was significantly higher (p < 0.0001) in both male (n = 67) and female (n = 35) obese subjects and showed a positive correlation (r = 0.4, p < 0.0001) with BMI. Serum levels of the angiogenic factors, vascular endothelial growth factor (VEGF) and angiopoietin were significantly higher in obese subjects. Levels of angiostatic factors such as angiostatin, endostatin were not altered in obese male subjects but were elevated in female obese subjects. Angiogenic potential and levels of VEGF did not vary in obese subjects with high HOMA-IR compared to obese subjects with low HOMA-IR. These results suggest that the angiogenic potential of serum was elevated in obesity and that insulin resistance may not contribute to the increased angiogenic potential in obesity.  相似文献

Discovering ethnic root behavior patterns: Towards an applied Canadian ethnic studies     

Dorothy Chave Herberg 《Int J Intercult Relat》1982,6(2):153-168

This paper reports a method used with six groups of either students or community professionals, since 1977, to experiment with inductive ways of identifying “ethnic root” behavior patterns. Such patterns are hypothesized to develop beyond the immigrant generation as ethno-culturat patterns and are passed on in the context of socialization. An acculturative framework is proposed to denote benchmarks in the cultural accomodation of individuals and families, through several generations. Along with this framework, the evolution of an ethnic behavior pattern is graphically depicted.A method is developed to identify the pattern beyond the level of conscious remembrance; (it is assumed that adult immigrants will remember the patterns from the country of origin). Although the method is interesting as an avenue of investigation in its own right, it was developed primarily as a conceptual tool to assist community professionals to understand ethnic-related material in their daily work. Three uses of the framework are outlined. First, it draws attention, in the counselling situation, to the level of integration into Canadian society that the client displays. Second, by getting in touch with the personal ethnic pattern that they own, the practitioner him/herself begins to understand the nature of ethno-culture, and thereby appreciate the presence of it in others. Third, the method permits the practitioner to identify personal values of an ethno-cultural sort that can interfere with practice.  相似文献
