摘要:
The present invention provides a security module for Web application, especially a portal application, using a rewriter proxy. The security module ensures that the rewritten URIs are appended by an authentication identifier for determining whether the rewritten URI has not been changed. Preferably, the authentication identifier can be generated by applying a secure hash algorithm and/or secret key to the original URIs of the remote resource or the entire rewritten URIs. When a client activates those URIs, a request is sent to the rewriter proxy. Before a connection to the access protected remote resource is established, the security module validates whether the URIs contained in the user client request have been changed by the user.

A posture assessment and feedback instrument (FIG. 1A and FIG. 1B) all contained within a single housing (1). The output of a capacitive sensor (4) within the housing (1) varies in response to the distance between the sensor and the body of a user. The housing (1) is strapped to the body of a user (FIG. 3, FIG. 4, FIG. 5A, and FIG. 5B) with a belt (2). The application area is chosen such that the distance between the sensor (4) and the body varies in response to a defined posture change (FIG. 5A and FIG. 5B). Thus the sensor output will vary in response to the defined posture change. The output is compared to a stored threshold value and triggers a feedback signal when the threshold is exceeded.

The invention provides a process for the preparation of polycarbonate by the melt transesterification process, polycarbonate having a low electrostatic charge obtainable by this process, and mouldings or extrudates, in particular optical data storage media or light-diffusing plates, made from this polycarbonate.
摘要:
A degreasing method for descaling or removing laser scales from iron-containing metal part surface by treating the iron-containing metal part surfaces that is optionally tainted with laser scales with an aqueous solution containing at least one type of highly water-soluble and complexed with Fe ions carboxylic acid, at least one type of salt of at least one type of carboxylic acid exhibiting the same action and at least one type of fatty amine ethoxylate, wherein the solution is buffered, the Fe ions are carried into the solution and at least partially complexed, increasing the pH value of the solution for descaling with respect to at least one type of carboxylic acid. The entire concentration of carboxylic acids and the salts thereof is increased for descaling by 2 to 20% by weight.

The invention relates to a process for the removal of deposits formed in a reaction apparatus by the precipitation of solids from a liquid reaction mixture, which process is characterized in that particles of a material that is inert under the reaction conditions are introduced into the reaction apparatus, which particles, by suitable mechanical circulation of the reaction mixture, are so moved through the reactor that, during the reaction, by striking the walls or other built-in elements, they abrasively remove precipitates adhered thereto.

The present invention relates to compounds of formula 1 or pharmaceutically acceptable salts thereof, wherein one of R1 and R2 is methyl, ethyl or isopropyl, and the other is H; R3 and R4 are each independently H, branched or unbranched C1-C6 alkyl, or aryl, and wherein at least one of R3 and R4 is other than H; R5 is a branched or unbranched C1-C5 alkyl group or a C1-C6 cycloalkyl group, each of which may be optionally substituted with one or more OH groups; R6, R7, R8 and R9 are each independently H, halogen, NO2, OH, OMe, CN, NH2, COOH, CONH2, or SO2NH2. A further aspect of the invention relates to pharmaceutical compositions comprising compounds of formula 1, and the use of said compounds in treating proliferative disorders, viral disorders, CNS disorders, diabetes, stroke, alopecia or neurodegenerative disorders.

摘要:
The present invention relates to p21 derived peptides capable of inhibiting CDK/cyclin complexes, particularly cyclins A or E/CDK2, by modifying the interaction with their substrates. The peptides are derived from a C-terminal region of p21 and display selectivity for cyclin/CDK2 inhibition over cyclin/CDK4 inhibition. Variants of such peptides particularly involving certain alanine replacements are shown to be particularly potent.
