海胆壳多糖的提取及PMP柱前衍生化高效液相分析

目的建立海胆壳多糖提取工艺及柱前衍生化条件。方法水提醇沉法提取壳多糖,采用正交实验优化提取工艺;柱前衍生化后,利用高效液相色谱法检测单糖组分,对海胆壳多糖的脾淋巴细胞免疫抑制活性实验进行了初步探索。结果海胆壳多糖最佳提取工艺为15倍的水,70℃水浴回流1 h,提取3次;100μl壳多糖水解液,加入50 ml Na OH(0.2 mol·L-1),40μl l-苯基-3-甲基-5-吡唑啉酮(0.5 mol·L-1),混匀后70℃水浴30 min,取出冷却,加入50μl HCl(0.2 mol·L-1)中和,200μl氯仿萃取3次。药理学实验表明海胆壳多糖溶液在浓度1~10μg·ml-1范围时显示出一定的免疫活性。结论本次实验成功建立海胆壳多糖的提取工艺和衍生化条件。     

The Bundeswehr and the Kunduz air strike 4 September 2009: Germany's post-heroic moment?

The article sets out to investigate Germany's involvement in the controversial 2009 Kunduz air strike in Afghanistan. Utilizing a theoretical framework derived from existing literature on postheroic warfare, it employs a detailed case study of this particular military engagement to highlight the operational, strategic, and cultural dimensions of Germany's operations in Afghanistan. Through an analysis of primary documents and field interviews, this paper concludes that German public opinion, politicians, soldiers and media reacted in ways that mirror closely theories of postheroic warfare. These included widespread condemnation of the air strike, increasing doubts about the Afghan mission, and emphasis on low-risk stand-off precision weapons, which paradoxically resulted in higher civilian casualties. Germans still have a long way to go to accept the brutal realities of military engagements that the Bundeswehr increasingly confronts during its expanded scope of post-cold war military operations.     

论金融功能监管:金融监管核心思想--从全球金融监管新发展看中国金融监管法律变革

随着我国“入世”,民族银行业面临巨大挑战,我国金融监管更面临严峻考验。我国金融业走向混业经营已成必然,应在分析借鉴美国《金融服务现代化法》及澳、日、德、英、加等国立法与理论的基础上,建立功能监管体系,完善我国的金融监管。     

一起贪污案司法会计检验鉴定的思考

司法会计检验鉴定,不仅要重视对涉嫌犯罪的事实进行检验鉴定,也要重视对证实犯罪嫌疑人无罪的事实的检验鉴定。司法会计应以独立、客观、公正、科学的立场去发现、搜集、检验和审查财务会计资料及相关证据,鉴别、判定财务会计问题,达到既及时准确揭露犯罪、证实犯罪,又能保障犯罪嫌疑人的合法权益。     

扩大我国对泰国蔬菜出口的对策建议

中国与泰国具有广泛的经贸合作关系,2004年我国成为泰国的第二大进口国和第三大出口国,是泰国的第三大贸易伙伴①。在我国农产品的出口中,蔬菜出口占有比较重要的地位,2001年、2002年和2003年我国蔬菜出口数额分别为17.45亿美元、18.83亿美元和21.80亿美元,占农产品出口总额的比重分别为11.30%、10.82%和10.56%。由于泰国的气候不适宜生产蔬菜,因此我国的蔬菜在泰国有很好的市场。2003年10月1日,中泰果蔬零关税协定正式生效,这对于扩大我国对泰国蔬菜出口是一个很好的契机。本文的蔬菜指的是海关统计商品目录第七章下的食用蔬菜、根及块茎。…     

行政法本质的“相对论”

本文在运用“解构”方法对行政法本质的传统研究范式之弊端进行剖析的基础上 ,指出科学认识其本质的途径在于转换研究范式 :以“相对论”的视野在运动、变化、发展中 ,将行政法的基本矛盾双方 ,置于不同参照系下进行考察 ,从而得出行政法的本质具有相对性 ,动态性和开放性的特征 ,存在于确定性与非确定性、运动与静止、应然与实然的统一过程中。     

A Study of Nation Building in Malaysia

Nation building is a major issue in the political agenda of many countries, a project made more arduous in countries fragmented along racial, linguistic, and religious lines. In an attempt to gain some understanding of the issue, this paper examines the trajectory of nation building in Malaysia. Basically, the Malaysia government uses the model of nation-state to create a sense of collective national identity in a multi-ethnic society. It is a top-down approach with the state playing a dominating role. The main political parties are communal parties, based on race or religion. Well-crafted programs of nation building have been not properly implemented. While the government has achieved impressive economic development, it is at the same time becoming more authoritarian and the country faces a range of disturbing social and political problems. Thanks to a growing educated middle class, urbanization, demographic change, globalization, and the spread of the Internet, mass-based civil movements and a multi-ethnic coalition of opposition parties have emerged with the potential of redressing the situation. The study suggests a framework for understanding the trajectory and dynamics of the nation-building project in Malaysia. The framework gives a list of historical forces that are likely to shape the course of nation building in the coming years.
