非目的片段对mtDNA测序影响的实验观察

目的通过重新设计引物,去除非目的片段对mtDNA测序的影响。方法在目的片段原引物内侧重设计引物,用该引物替代原引物进行测序,其测序图谱与原图谱进行对比。结果重新设计引物后,获得了清晰的序列图谱。结论通过重设计引物消除了非目的片断对mtDNA测序的影响。     

我国加入WTO后跨境犯罪动向预测

加入WTO将使我国融入国际经济的大潮之中 ,跨境犯罪也会因此而呈现出发案数上升 ,作案手段更加隐蔽 ,有组织犯罪的危害扩大 ,高科技犯罪频繁发生 ,犯罪分子寻找权力保护的意识增强的新动向。国家强力机关应当根据这些新情况进行必要的战略调整 ,以有效控制跨境犯罪的发展蔓延势头。     

成人仪式:从生活教育到政治教育

传统的成人仪式在现代法治社会已不具有存在的必要性,但由于政治权力的征用从而实现了其由生活教育到政治教育的现代转变,主要体现在主持主体、仪式内容、仪式过程和仪式效果几个方面。如何使生活教育的内容不被闲置,保证仪式效果,是值得认真思考的问题。     

犬瘟热病毒野毒株与疫苗株联合RT-PCR鉴别方法的建立

为了建立快速、有效的鉴别犬瘟热病毒(CDV)野毒株与疫苗株的诊断方法,根据CDV野毒株与疫苗株N基因的保守区域以及H基因的多变区域设计特异性引物,建立了区分CDV野毒株与疫苗株的联合RT-PCR方法.结果表明,针对N基因的RT-PCR方法能同时检测CDV野毒株与疫苗株;而针对H基因的RT-PCR方法只能检测CDV野毒株,不能检测CDV疫苗株.根据2次RT-PCR反应结果,能够很好地区分CDV野毒株与疫苗株.同时,经过病毒电镜观察和H基因扩增片段的克隆测序结果的比对,进一步确认了该方法的特异性.表明,该方法具有快速、特异、实用等优点,可作为CDV鉴别诊断的有效手段.     

中国物权法草案的修改意见:总体结构与制定目的

在中国民法典制定进程中,单行法模式也是一种较为现实的选择。全国人大常委会2004年10月15日委员长会议审议稿《中华人民共和国物权法(草案)》采五编制结构,虽不失严谨,但也是作茧自缚。物权法在总体设计上应该采取较为松散的结构模式。一种可供选择的总体结构包括12章和附则,依次为:通则,所有权,关于土地、矿藏、森林、草原、江海湖泊等自然资源的使用,地役权,居住权,典权,抵押权,质权,留置权,让与担保,优先权,占有,以及施行法。作为一部单行法,物权法在第1条中规定立法目的是有必要的。草案第1条规定基本上体现了物权法的价值取向,但也有失宽泛。建议将该条修改为:“为了保护物权权利人的民事权益,明确物的归属,充分发挥物的效用,制定本法。”     

Old Trade, New Opportunities

ANIMAL husbandry is the new leading industry within Fujian's rural economy and in certain localities contributes appreciably towards increasing farmers' incomes. In Guangze County, for instance, more than 60 percent of rural households are involved in animal husbandry, and earnings they generate from it account for 55.6 percent of their total income. "In the past, farmers earned RMB 400-500 per mu (15 mu = 1 hectare) of farmland. Since the Sheng-nong Group was established in Guangze County, they have been making almost     

Small Town with a Great History

XIAOZHAN Rice is a household name across China, but few realize that Xiaozhan is also the name of the town where this delicious rice is produced. The town proper is only 3.5 square ki- lometers in size, but small as it is, 100- year-old Xiaozhan Town has contributed a short but brilliant chapter to modern Chinese history. "West Point" of the Beiyang Era Located 25 kilometers from down- town Tianjin, Xiaozhan is part of Jinnan, a suburban district of the municipality. The town looks imp…     

Break the Resource Bottleneck, Seek a New Development Path—— A Visit to the Henan Provincial Bureau of Nonferrous Metal Geology and Mineral Resources

CHINA's economic growthis charging forward atbreakneck pace, but sus-tainable development ofits building blocks - rawmaterials - is a cause of concern. Theproduction of nonferrous metals - keycomponents of other industrial prod-ucts - is being threatened by depletingmineral resources. Proved and exploit-able mineral reserves have decreaseddramatically in recent years, and someexperts have predicted that only 24 ofChina's 45 main mineral reserves canguarantee supply until 2010, and onlyfour u…
