摘要:
A composition and use thereof for the prophylaxis or treatment of Alzheimer's disease, motor neurone disease, Lewy body disease, Pick's disease or progressive supranuclear palsy. The composition includes an agent which modulates or inhibits tau-tau association and which does not inhibit tau-tubulin binding. In the method the agent is administered to an individual in order to achieve the desired therapeutic effect. Preferably the agent which is administered is a phenothiazine compound.

A method for analyzing data from a database using an analytic database function includes receiving a selection of measured items from a user, receiving a placement item from the user, and determining a partitioning of the selection of measured items from the placement item. A placement item can be a column, a row, or an axis. A template associated with the analytic database function is adapted to define at least one partitioning relative to the placement item. The template is further adapted to define an ordering parameter for the analytic database function and optionally an aggregation level for the analytic database function. A database query is created with the partitioning. The database query can be an SQL statement.
摘要:
The present invention relates to a resin composition comprising an at least bifunctional prepolymer (A) curable under ection of heat, a telechelic elastomer and a particulate material having an elastomeric core and a thermoplastic shell. Layers and patterns which are produced using the formulation according to the invention have excellent adhesion properties, chemical stability, good electrical properties and high resistance to rapid temperature ranges. The compositions are suitable in particular as solder resists in the production of circuit boards.
摘要:
A temperature regulator operating with a hydraulic expansion capsule or diastat (5) has a lever mechanism (30) for force transmission between the diastat and the switch spring (21) of a snap switch (20). For protecting the switch spring against overloading, into the lever mechanism is integrated a buffer or shock absorber, which is elastically flexible above a limit force associated with the operating force of the switch spring in the switching point and below the limit force is substantially rigid. The standard unit formed by the shock absorber and the lever mechanism is formed by a rocker (31) in the form of a sheet metal bent part, which has a L-shaped pivot lever portion (40), with which is constructed in one piece a stop-limited opening clip spring (41) pretensioned in the opening direction.

摘要:
Oligomeric cyanoguanidines of formula I ##STR1## wherein, for example, R.sup.1 and R.sup.2 are each phenyl, R is 1,4-phenylene and n is an integer from 1 to 20, are suitable latent hardeners for epoxy resins. They are readily soluble in solvents suitable for the application of epoxy resins, and the cured products obtained therewith have a high glass transition temperature.
摘要:
Compounds of the formula I ##STR1## in which X is O, S, SO, SO.sub.2 or NR.sub.13, R.sub.13 is, for example, methyl, and R.sub.1 to R.sub.12, independently of one another, are, for example, H, C.sub.1 -C.sub.12 alkyl, C.sub.1 -C.sub.12 Alkoxy, halogen or --CN. The compounds are photosensitive and photochromic and are suitable as photosensitizers and simultaneously as color indicators, and as photoswitchable color filters.

摘要:
Titanocenes containing .pi.-cyclopentadienyl ligands, in which one or two carbocyclic or heterocyclic aromatic rings are attached to the metal atom, said aromatic rings being substituted by fluorine in at least one of the two ortho-positions relative to the metal-carbon bonds, are suitable photoinitiators for the photopolymerization of ethylenically unsaturated substrates. They are distinguished by high sensitivity, stability to air and heat, and are very effective in the range from UV light to visible light.
