人文关怀视野中的读者权利与图书馆员权益

本文强调了尊重读者权利和保障图书馆员权益是图书馆人文关怀的重要内容,在图书馆的服务过程中既要强化对读者的人文关怀,也要体现对图书馆从业人员的人文关怀,只有解决好从业人员和服务对象的人文关怀问题,图书馆的人文精神才能全面体现。     

激光焊接保护气嘴结构设计

针对高功率激光焊接过程中的气体保护问题,设计了三管组合保护气嘴结构。对保护气嘴的倾角以及三管气嘴的间距进行精确设计,三管组合保护气嘴通过三向活动导向臂与焊接头固定,并且可以很方便的调节气管方向及与焊缝的位置。通过和单管及双管保护气管的焊接效果相比较,三管组合保护气嘴结构可以得到光亮、平整的焊缝效果。

中国医药制造业企业政府创新补贴绩效研究

政府创新补贴逐渐成为企业研发资金的主要外部来源,但其对企业绩效的作用机制仍然模糊。根据医药制造业企业研发周期长、风险大的特点,在考虑时滞效应的基础上运用STATA12. 0构建静态回归模型,从微观角度分析政府创新补贴的创新绩效和财务绩效,以及在不同地区、不同企业性质和不同规模企业中的差异。研究表明:政府创新补贴会显著促进当期的研发投入,并且这一作用在东部地区、国企和小规模企业中表现更显著;政府创新补贴对未来一期的创新产出呈正U型关系,这种关系在东部地区、不同性质和不同规模企业中均显著;政府创新补贴对未来一期的财务绩效产生显著促进作用,这种促进作用在东部地区、小规模和非国有企业中表现更显著。研究结论对我国政府合理制定政府创新补贴政策和医药制造业提高创新能力提供了决策依据。     

A molecular biological study on identification of common septicemia bacteria using 16s–23s rRNA gene spacer regions

In the search for a rapid and reliable method for identification of bacteria in blood and cerebrospinal fluid , we developed a unified set of primers and used them under polymerase chain reaction(PCR) to amplify the spacer regions between the 16s and 23s genes in the prokaryotic rRNA genetic loci . Spacer regions within these loci showed a significant level of length and sequence polymorphism across most of the species lines. A generic pair of priming sequences was selected from highly conserved sequences in the 16s and 23s genes occurring adjacent to these polymorphic regions. This single set of primers and reaction conditions were used for the amplification of the 16s-23s spacer regions for 61 strains of standard bacteria and corresponding clinical isolates belonging to 20 genera and 27 species, including Listeria, Staphylococcus and Salmonella species, et al. When the spacer amplification products were resolved by electrophoresis, the resulting patterns could be used to distinguish most of the bacteria species within the test group, and the amplification products of the clinical isolates clustered at the standard species level. Some species presenting similar pattern were further analyzed by HinfI or AluI digestion or DNA clone and sequences analysis in order to establish the specific 16s-23s rRNA gene spacer regions map. Analysis of 42 blood specimens from septicemic neonates and 6 CSF specimens from suspected purulent meningitis patients by bacterial culture and PCR-RFLP(Restriction Fregament Length Polymorphism) showed that 15 specimens of blood culture were positive(35.7%) in the 42 septicemic neonates; 27 specimens were positive(64.2%) by PCR, and that the positive rate by PCR was significantly higher than that by blood culture(P<0.01). Among the 6 CSF specimens, one specimen found positive by blood culture was also positive by PCR, two found negative by blood culture showed positive by PCR; all three were S.epidermidis according to the DNA map. One C.neoformans found positive by blood culture showed negative by PCR. The remaining two specimens were both negative by PCR and blood culture. These results indicated that the method of detecting bacterial 16s-23s rRNA spacer regions using PCR and RFLP techniques was rapid, sensitive and specific in the detection of bacterial infections; and so, has very important application in the clinical diagnosis of sepsis in neonates.
