Abstract: An information technology (IT) system of interest is analyzed using collaborative, community-based sharing of expert knowledge, analysis and advice through user-submitted analysis rules and/or user-submitted report templates. Users may submit rules that have been found to be useful in analyzing or managing IT systems. A rule may analyze a particular item of configuration data or performance data according to a predetermined criterion. Other users may apply these rules to their own systems' data and, thereby, utilize the collective expertise of the people who submitted the rules. Performance and configuration data from IT systems or components of the systems in various enterprises is collected and then sanitized by removing or masking identifying information before storing the sanitized data in a data warehouse. An IT manager may compare data from his/her IT system to historical data from the system or to data from IT systems having similar workloads, configurations, problems or according to other matching criteria, without obtaining confidential information about the comparison systems. Such comparisons may use the user- submitted rules. Reports are generated from these analyses and comparisons according to predefined and/or user-submitted report templates and report component templates for items such as text blocks, tables, graphs, charts and block diagrams.

Abstract: Alors que le milieu et des systèmes de culture ont été décrits permettant la culture et la prolifération de cellules souches embryonnaires humaines dans des conditions exemptes d'alimentation et exemptes de produits d'origine animale, ces conditions ne vont pas nécessairement permettre le clonage d'une culture de cellules souches embryonnaires, c'est-à-dire, au moins dans le cadre présent, l'initiation d'une sous-culture au moyen d'une ou d'un très petit nombre de cellules dd départ. On a observé dans ce cas qu'une classe de petites molécules qui sont inhibitrices d'enzymes kinases vont accroître l'efficacité de clonage de cultures de cellules souches suffisamment pour rendre un tel clonage pratique dans le milieu défini ainsi que dans d'autres milieux.

Abstract: A two layer fabric has first, second, third and fourth upper side wefts contiguously and repeatedly arranged. Each of three contiguously arranged warps forms a knuckle over second, over third, and over second upper side wefts respectively to form a separation portion. At both sides of the separation portion, both the second and third upper side wefts form a float portion by passing over two or more warps. Adjacent to the float portion, one warp passes over the second and third upper side wefts successively and one or two warps adjacent thereto pass over the second or the third upper side weft to form an approach portion where the second and third upper side wefts approach. Crimp portions are formed to sandwich the separation portion where the first and fourth upper side wefts pass over warps which are common to those of the separation portion.
