Issues in information malpractice     

Puckett M  Ashley P  Craig JP 《Medical reference services quarterly》1991,10(2):33-46

In today's information explosion environment, the health sciences librarian is increasingly placed in the role of interpreting, translating, and evaluating information for clientele. With this emerging role and the burgeoning of fee for service programs, the question of information malpractice liability becomes an increasingly important issue. This paper explores the basis for legal actions against librarians and offers some precautionary measures to help protect against such legal action.  相似文献   

Magnaporthe oryzae MTP1 gene encodes a type III transmembrane protein involved in conidiation and conidial germination     

Lu Q  Lu JP  Li XD  Liu XH  Min H  Lin FC 《Journal of Zhejiang University. Science. B》2008,9(7):511-519

In this study the MTP1 gene, encoding a type III integral transmembrane protein, was isolated from the rice blast fungus Magnaporthe oryzae. The Mtp1 protein is 520 amino acids long and is comparable to the Ytp1 protein of Saccharomyces cerevisiae with 46% sequence similarity. Prediction programs and MTP1-GFP (green fluorescent protein) fusion expression results indicate that Mtp1 is a protein located at several membranes in the cytoplasm. The functions of the MTP1 gene in the growth and development of the fungus were studied using an MTP1 gene knockout mutant. The MTP1 gene was primarily expressed at the hyphal and conidial stages and is necessary for conidiation and conidial germination, but is not required for pathogenicity. The Deltamtp1 mutant grew more efficiently than the wild type strain on non-fermentable carbon sources, implying that the MTP1 gene has a unique role in respiratory growth and carbon source use.  相似文献

INTRODUCTION Researchers continue to develop non-destructive methods to evaluate the effect of their impact on ag-ricultural products using high-tech methods. Non-destructive techniques sensing has been applied for obtaining fruit and vegetable quality index. Non-destructive method for measuring firmness us-ing sonic or vibration characteristics applied in pre-vious investigations was recently reviewed by Arm-strong (1989) and Liljedahl and Abbott (1994). The sonic vibration technique u…  相似文献

Preparation and in vitro studies of microencapsulated cells releasing human tissue inhibitor of metalloproteinase-2     

Jiang Q  Zhang SZ  Peng JP  Wang XL 《Journal of Zhejiang University. Science. B》2005,6(9):859-864

INTRODUCTION Cell encapsulation in biocompatible and semipermeable polymeric membranes is an effective method for immunoprotection, regardless of the type of recipient (allograft, xenograft, etc.). The semipermeable nature of the membrane prevents high molecular weight molecules, antibodies and other immunologic moieties from coming into contact with the encapsulated cells and destroying them as foreign invaders, but permits the entry of nutrients and oxy- gen and the exit of therapeutic p…  相似文献   

Promoter trapping in Magnaporthe grisea   总被引：1，自引：0，他引：1  

Liu XH  Lu JP  Wang JY  Min H  Lin FC 《Journal of Zhejiang University. Science. B》2006,7(1):28-33

INTRODUCTION Magnaporthe grisea is a filamentous ascomy- cete that parasitizes economically important crops, such as barley, wheat, and rice (Talbot, 2003). It is also a good experimental model for studying fungal pathogenesis by both classical and molecular genetics (Dean, 1997). In recent years, many techniques have been developed to identify functional genes in M. grisea (Kamakura et al., 1999; Rauyaree et al., 2001; Takano et al., 2003; Irie et al., 2003; Lu et al., 2005). Of these…  相似文献

网络空间是现实空间的延伸，是对现实空间的虚拟，是现实空间的映射。网络空间与现实空间的差异是导致网络信息传播中矛盾与冲突的根本原因。其矛盾与冲突表现在八个方面：网络开放性与网络安全性；信息主权与信息霸权；信息超载与信息短缺；信息污染与信息有效性，信息共享与信息垄断；个人隐私与社会监督；信息利用与知识产权保护；信息自由主义与社会责任。  相似文献

Validity of vertical jump measurement devices     

Buckthorpe M  Morris J  Folland JP 《Journal of sports sciences》2012,30(1):63-69

Vertical jump height is thought to provide a valuable index of muscular power, which is an important factor in sports performance and for assessing the mobility and functional capacity of injured or aged individuals. The purpose of the present study was to investigate the criterion validity of four popular devices for measuring vertical jump height. A belt mat, contact mat, portable force plate, and Vertec were compared to a criterion device, a laboratory force plate. Forty participants performed three maximal countermovement jumps on each device in a counterbalanced order, using block randomization. The criterion device presented the highest mean value (50.3 cm). The portable force plate and belt mat devices recorded similar jump height values to the criterion device (within 1 cm). The contact mat and Vertec devices recorded significantly lower values than the criterion device (P < 0.001). The mean difference ± limits of agreement were: belt mat -0.1 ± 5.5 cm, contact mat -11.7 ± 6.4 cm, portable force plate -0.8 ± 3.9 cm, and Vertec -2.4 ± 6.6 cm. In conclusion, the portable force plate and belt mat devices provided valid measures of vertical jump height, whereas the Vertec and contact mat devices did not.  相似文献
