摘要:
A crash box for a motor vehicle, having at least one crash box component which is deformable in the event of a collision, and which in the event of a collision absorbs energy as a result of the deformation. The crash box includes at least one weakening tool which, for adjusting the energy absorption capability of the crash box component, weakens the overall structure of the at least one crash box component, as a result of which the rigidity of the crash box component is reducible.
摘要:
Provided is a process for esterifying or transesterifying side chains in polymers, which involves esterifying or transesterifying the carboxyl group having the R4 radical of a copolymer obtained by polymerizing a (meth)acrylate of formula (I), and a monomer of formula (II): wherein R1 and R3 are independently H or CH3, R2 and R4 are independently H or an alkyl radical which is optionally substituted by functional groups such as acryloyl, ether, amino, epoxy, halogen or sulfonic acid groups, and n is from 1 to 40, with an alcohol in the presence of an enzyme which catalyzes the esterifying or transesterifying. Further provided is the esterified or transesterified polymer product and its use.

摘要:
A micromechanical structure, includes at least two structure sections configured to bound a working gap, the at least two structure sections being movable relative to one another, and a working gap width setting device configured to broaden the at least one working gap by movement of a first structure section of the at least two structure sections relative to a second structure section of the at least two structure section, the first structure section is stationary relative to a reference point during operation of the micromechanical structure and (ii) the second structure section is movable relative to the reference point during operation.
摘要:
A material composite has at least one region of copper or a copper alloy, at least one region of a predominantly graphitic material, and at least one boundary region between them. The boundary region has one or more carbides from the group of the IVb, Vb, VIb transition metals and one or more elements of the group consisting of Si, B, Al, Ge, Mn, Sn. In a preferred implementation of the invention, the composite is produced with a back-casting process.

The present invention relates to proteins having an enzymatic activity of reducing substituted alkanones such as 3-methylamino-1-(2-thienyl)-propan-1-one. The invention furthermore relates to nucleic acids coding for said proteins, nucleic acid constructs, vectors, genetically modified microorganisms and to methods for preparing optically active substituted alkanols, such as, for example, (S)-3-methylamino-1-(2-thienyl)-(S)-propanol.
摘要:
A method to be performed in a process of a computer system initiating physical operations includes receiving, in a computer system, a request to generate a first object and a second object. The first object is to be used in initiating a manufacturing-type operation and the second object is to be used in initiating a warehouse-type operation. The method includes generating the first object and the second object in response to the request. The first and second objects are generated using an object model for physical operations. A computer system includes a first resource and a second resource, and an object generating module configured to generate the first and second objects.
