牦牛肠道与粪便乳酸菌的分离鉴定及PCR-16 S rDNA鉴定

以取自四川省不同地区的牦牛粪便、肠道内容物为材料,用MRS琼脂双层培养基进行厌氧培养,分离到50株乳酸菌,经生化鉴定为嗜热链球菌(2株)、乳酸乳球菌(1株)、保加利亚乳杆菌(5株)、嗜粪乳杆菌(10株)、嗜酸乳杆菌(8株)、乳酸乳杆菌(9株)、肠乳杆菌(10株)、弯曲乳杆菌(5株)。采用乳酸菌16 S rDNA通用引物,对分离的8种菌的16 S rDNA一段可变区序列进行扩增,均得到大小约470 bp的产物;扩增产物经纯化、测序后与GenBank中标准菌株的核甘酸序列比较,同源性均大于97．5％,同源性分析与生化试验的结果是一致的。证实,牦牛肠道和粪便的乳酸菌较为丰富,且乳杆菌的数量较多,这可能与牦牛复杂的生长环境有关。     

论晚唐“苦吟”的内蕴流变

在中晚唐诗歌史上,姚、贾虽以苦吟并称,但思想境界的不同、时代士风的变迁,已使二人的诗歌精神产生巨大差异.从孟郊、贾岛到姚合,随着苦吟的内蕴变化,诗人的艺术追求也发生了重要变化.姚合上承王维及大历诗人,融汇张籍、贾岛等诸家之长,成为苦吟诗人的集大成者.他所追求和倡导的"清峭"诗风,代表了晚唐苦吟诗人共同的审美趋向.这是他们在艺术旨趣上最终选择姚合,远离贾岛,形成情感平和、风格雅正创作格局的根源.     

高锌对雏鸡红细胞免疫功能的影响

将 1日龄艾维茵肉鸡雏 2 0 0只随机分为 4组 ,Ⅰ组为对照组 ,Ⅱ～Ⅳ组为试验组 ,分别饲喂不同日粮 ,Ⅰ组 :基础日粮 (含Zn 10 0mg/kg) ,Ⅱ组 :基础日粮 Zn 1 4 0 0mg/kg ,Ⅲ组 :基础日粮 Zn 1 90 0mg/kg ,Ⅳ组 :基础日粮 Zn 2 4 0 0mg/kg ,试验期为 7周。结果发现 ,日粮高锌可导致雏鸡红细胞C3bRR花环率降低 ,ICR花环率升高。Ⅱ、Ⅲ、Ⅳ组C3bRR花环率 2周龄时显著下降 (P <0 .0 1) ,Ⅲ、Ⅳ组第 5和 7周龄时也极显著低于Ⅰ组。Ⅳ组ICR花环率 2周龄时显著高于Ⅰ组 (P <0 .0 5 ) ,Ⅱ、Ⅲ组ICR花环率也有所升高 ,但与对照组比较 ,仅Ⅱ组于 5周龄时差异显著 (P <0 .0 5 )。     

毛细管电泳在毒品检验中的应用

毛细管电泳因其自身特性而适用于毒品检测。本文重点对毛细管电泳的五种模式在毒品检验中的应用进行了综述和比较 ,包括各自检测方法的应用范围、优点和局限。     

论公安机关解决民事纠纷的正当性

公安机关解决民事纠纷的制度虽然没有明确的法律依据,但可以从正当性的视角对其进行分析。由于其具有客观上的合理性,也得到了人们的普遍接受与认同,因此符合正当性的客观性与主观性要件,具有正当性。     

略论中国的选择性保障措施

我国在《入世议定书》中承诺的过渡性保障措施本质上是一种选择性的保障措施,其规定的实施条件比WTO《保障措施协议》要宽松,这是一种不公平的规定,我国应在履行协议时通过解释争取变更这种不利处境。     

论侦查比例原则的构建

侦查比例原则是通过对侦查目的与手段之间的关系的衡量 ,把侦查权限制在适度、必要的限度之内。确立这一原则是由侦查权的性质、特征以及我国侦查立法和实践的需要决定的。构建侦查比例原则应从改革和完善现有的审前裁判机制、区分任意侦查与强制侦查、改革和完善替代羁押措施三个方面入手。     

论我国预重整之程序构建北大核心SSCI

预重整制度有利于企业债务重组与破产重整程序的高效衔接,我国近年相关政策性文件亦强调要积极探索建立预重整制度。从目前各地法院的司法实践来看,因缺少预重整的基本理论共识,各地法院在适用预重整程序方面做法各异,有必要总结我国各地法院的预重整经验,构建起统一且适合我国的预重整程序规范。预重整程序的构建需以预重整的内涵、性质及形式等理论问题为其逻辑前提,在此基础上本文提出我国预重整的形式应采取庭内预重整,明确预重整的强制性效力,同时构建起以法院为主导的预重整程序,包括预重整的启动、临时管理人的产生、预重整方案的制定和法院的审查受理等。预重整制度在我国确立与发展,不仅需要借鉴域外预重整的制度规范和先进理念,更需要根据我国的现实环境进行培育,需要我国立法、司法与理论界的积极推动以及政府、法院与当事人之间的有效互动。     

The differential experience of Mozambican refugee women and men

This study examines differences in Mozambicans mens' and womens' experiences of living in refugee camps in Malawi late in 1990. The aim is to identify the differences in impact by gender in assistance policies and programs. In early 1991 there were an estimated 1 million Mozambican refugees in Malawi. This study is based on quantitative and qualitative data collection. The study sample included Chiumbangame and Mwawa in Mangochi District (refugee camps) and Ntcheu (settlements integrated with Malawi's population). Findings indicate that 17% of the 2006-person sample were female-headed households. Men in general had more years of schooling than women. 34% of the women and 47% of men completed at least 1 year of school and 10% of women and 24% of men completed 2 years. At all ages boys were more likely to be enrolled than girls. 4.1% of the 847 persons over 18 years old were receiving some training, but only 1 person had increased household income due to training. Refugee income was nil for women and about 20 cents/day for men. The mean daily income for individuals from female headed households was about half that of income from male headed households. Women were more likely to be working and spent more time in productive work than men. Women worked in household maintenance. Women in income programs gave housework chores to younger females in the household. The income programs were of low quality and products had low marketability. Girls helped with housework from an early age, while boys helped as teenagers. 44.2% of female headed households and 34.9% of members of male headed households reported health problems. This study identifies the ways in which refugee policy worsens gender inequalities in economic production and work burden.     

女性学专业"性别与法律"课程教学探索

"性别与法律"是女性学专业开设的法学类特色课程,它属于主题性课程或领域性课程、视角或方法性课程,具有批判与建构并重的特征,且研讨性教学应占较大比重;它在内容编排上应分为导论、总论以及分论等3个部分,后者宜按中国特色社会主义法律体系组成划分为若干讲.目前该课程存在难度大、无合适教材和对教师要求高等问题,据此可运用电影教学、文献阅读、性别平衡和研讨方法,以此激发学生积极性、培养其能力并最终提升教学效果.
