摘要:
A method for the spatially resolved introduction of an intensity pattern of electro-magnetic radiation by at least one optic display system into a photosensitive substance having properties which can be changed by photon exposure. These properties include a first, liquid and at least one second state, with the electro-magnetic radiation being conducted via the optic display system into the photosensitive substance and here being projected on predetermined spatial coordinates, in order to create at or in an area of these spatial coordinates a change of the properties of the substance. A surface of an objective lens of the optic display system, through which the electro-magnetic radiation 4 is emitted, is immersed in the liquid photosensitive substance 2. A corresponding device is provided, and the device and method can be used for the creation of micro or nano-scaled structures.

The invention relates to a method for determining the binding constant of a compound of interest to proteins comprising the following steps: a) adding the high affinity compound to a two-chamber system, wherein the two chambers are separated by a semipermeable membrane, which is permeable for the compound of interest, and determining the amount of the high affinity compound of interest in one of the chambers after the distribution equilibrium has been reached, b) adding a sink compound to one of the chambers whereby the sink compound can not permeate the membrane, and determining the distribution coefficient of the compound of interest to the sink compound after the distribution equilibrium has been reached, c) adding an unspecific protein to the other chamber, whereby the unspecific protein can not permeate the membrane, and determining the distribution coefficient of the compound of interest to the unspecific protein in presence of a sink compound after the distribution equilibrium has been reached, and d) determining the binding constant of the test compound with the distribution coefficient of steps b) and c).
摘要:
A pressure fluid reservoir for a traction-controlled vehicle brake system; a reservoir unit including a plurality of pressure fluid reservoirs; and a method for producing a pressure fluid reservoir are disclosed. The pressure fluid reservoir with its structural size unchanged, has a larger installation space for a restoring element cooperating with a reservoir piston and at the same time can be produced economically. To that end, as the reservoir piston, a component reshaped in non-metal-cutting fashion from a sheet-metal material is proposed, on whose circumference an encompassing receptacle for a piston seal is integrally formed, likewise in non-metal-cutting fashion. The reservoir piston can be produced by deep drawing; the receptacle for the piston seal can be produced by roller-burnishing. Both method steps can be performed economically in one combined operation.
