适应、融入与发展——关于兰州市少数民族流动少年儿童义务教育适应问题的思考

随着城市少数民族流动人口的不断增加,城市少数民族流动少年儿童在城市接受义务教育存在着诸多的适应问题。如何让少数民族流动人口子女更好地适应城市义务教育环境,充分和平等地接受义务教育,本文以兰州市少数民族流动少年儿童义务教育为例,提出相应的分析和思考

The Inheritance of Ethnical Culture And the Adaptive Innovation of Educational Mode——Anthropological Perspectives on Hui Amateur Education in Lanzhou City

教育作为文化的生命机制,以其特有的方式作用于文化,同时教育也深受文化氛围、文化价值观的影响。近年来,在西北回族聚居地区形成了一种新型的教育模式——回族业余教育,是回族传统文化与社会主义文化相适应的产物,是回族传统教育与现代学校教育相适应的结果,是回族群体为了进一步提高群体成员的综合素质以及加强民族文化传承的一种有效探索。Based on the field works on the Chinese Hui Amateur education of Lanzhou in Northwest China,combined with case studies,questionnaire investigation and supplemented by depth interviews of Hui ethnic groups in urban community,to analyze Hui ethnic groups how to inherit and protect their traditional culture efficiently,In addition,the Hui traditional culture as an important part of Chinese Culture,how to adapt itself to today's Chinese society,It has a very important significance not only for the effective protection of traditional culture in our country,but for the construction of cultural diversity,harmony and unity of the Chinese Socialistic Culture

Fermentation Kinetics for Dextran Production by Leuconostoc mesenteroides CICC-21725

研究肠膜明串珠菌CICC-21725发酵产右旋糖酐过程。根据菌体生长量、蔗糖浓度和右旋糖酐产率与发酵时间的关系,采用Logistic Law方程和Luedeking-Piret方程,建立肠膜明串珠菌CICC-21725菌体生长动力学模型、产物合成动力学模型和底物消耗动力学模型。运用Matlab 7.0软件对实验数据拟合,获得模型参数。用红外光谱和核磁氢谱、碳谱对菌体发酵产物进行结构表征。结果表明:所建立的动力学模型的预测值与实验值吻合较好,拟合模型的相关系数分别为0.994 2、0.996 9和0.991 2,模型能较好的预测肠膜明串珠菌CICC-21725发酵产右旋糖酐的动力学过程。肠膜明串珠菌CICC-21725发酵过程中右旋糖酐的合成属于生长偶联型。红外光谱及核磁共振光谱结果表明肠膜明串珠菌的发酵产物是由为α-(1,6)糖苷键连接的直链α型右旋糖酐。The fermentation for dextran production by Leuconostoc mesenteroides CICC-21725 was investigated,a mathematical model was developed to describe the dynamic kinetics of the dextran production based on the Logistic Law equation for the Leuconostoc mesenteroides growth and the Luedeking-Piret equation for the dextran production.The date were calculated and analyzed by Matlab 7. 0 software. The fit degrees of the three individual models are0. 994 2,0. 996 9 and 0. 991 2 respectively. The results indicate a good agreement between the experimental data and the model predictions. The fermentation for dextran production is completely associate with the growth of Leuconostoc mesenteroides CICC-21725.广西高校人才小高地建设创新团队项目(桂教[2011]47);广西科技型中小企业技术创新资金(桂科转13109067);广西民族大学-广西化工研究院研究生联合培养基地专项资金资

基于UPLC/Q-TOF MS/MS的芝麻油成分分析Component analysis of sesame oil based on UPLC/Q-TOF MS/MS

为发现芝麻油中新成分，通过UPLC/Q-TOF MS/MS对4种芝麻油甲醇提取液进行检测分析。结果表明：4种芝麻油中共发现143种共同物质，其中正离子模式71种，负离子模式72种。共同物质中鉴定出77种物质，其余66种为未鉴定成分；77种鉴定成分中包括脂肪酸及衍生物（8种）、芝麻素、芝麻林素、硬脂酰胺等12种已知成分，其余65种为新发现成分；新发现成分包括油酸酰胺、棕榈酰胺、亚油酰胺、芥酸酰胺、8-甲基-N-香草基壬酰胺、辣椒酰胺、N-硬脂酰丙氨酸等17种脂肪酸酰胺，十六碳烯酸、十八碳烯酸等22种脂肪酸及衍生物，5-脱氧基维醇、天孢菌素等5种类黄酮，马泰树脂醇、银杏酸等21种其他成分。芝麻油中含有大量新成分和未知成分，富含的脂肪酸、脂肪酸酰胺、类黄酮、木脂素等物质可解释其独特生理功能。 In order to discover new components in sesame oil, the methanol extracts of four kinds of sesame oils were detected and analyzed by UPLC/Q-TOF MS/MS. The results showed that 143 common components in sesame oil were found, including 71 in the positive ion mode and 72 in the negative ion mode. A total of 77 components among 143 were identified, and the remaining 66 components were unidentified. The 77 identified components included 12 known components such as sesamin, sesamolin, eight fatty acids and derivatives and stearamide, and 65 newly discovered components. The newly discovered components included 17 fatty amides (erucamide, 8-methyl-N-vanillyl-nonamide, oleamide, palmitamide, linoleamide, capsiamide, N-stearoyl alanine, etc), 22 fatty acids and derivatives (hexadecenoic acid, octadeceneic acid, etc), 5 flavonoids such as 5-deoxyvitanol and tinosporinone, 21 other ingredients such as matairesinol, ginkgoic acid,etc. The sesame oil contains a large number of new and unknown components, and rich in fatty acids, fatty acid amides, flavonoids, lignans and other substances, which can explain its unique physiological functions
