摘要:
An NADP(H) nanosensor has i) a nucleic acid sequence to which a regulator is capable of binding, wherein the oxidation state of the regulator depends on the NADP(H) availability; ii) a promoter sequence following the nucleic acid sequence i), to which an RNA polymerase is capable of binding, wherein the affinity of the RNA polymerase for the promoter sequence is influenced by the oxidation state of the regulator; iii) a nucleic acid sequence which is under the control of the promoter sequence ii) and which codes for an autofluorescent protein. The present invention also relates to a cell, a method for isolating genes which code for NADP(H)-dependent enzymes, and the use of an NADP(H) nanosensor.

摘要:
A data communication system having a plurality of input/output ports, a first group and a second group of switching units. Each switching unit has a plurality of input/output interfaces, whereby at least one of the plurality of input/output interfaces of each switching unit of the first group forms an input/output port of the communications system, and at least one other input/output interface of each of the switching units of the first group is connected via a communication link with an input/output interface of one of the switching units of the second group, so that a network is formed having at least one loop. The network is logically divided in at least two virtual subnetworks, each forming a spanning tree. Each switching unit of the first group is configured to assign an incoming data packet arriving at a particular input/output port to a predetermined one of the at least two virtual sub-networks. An advantage of the present invention is the ability to transparently employ the taught data communication device in different computing environments, without the requirement to alter any external equipment.

The invention relates to a method for producing a strained layer. Said method comprises the following steps: placing the layer on a substrate and straining it, structuring the strained layer, relaxing the layer, producing directional off-sets in the layer to be strained. A layered structure produced in this manner has triaxially strained layers.
摘要:
Alloys containing aluminium are characterised by an outstanding oxidation resistance at high temperatures, that is based on, inter alia, the formation of a thick and slow-growing aluminium oxide layer on material surfaces. If the formation of the aluminium oxide layer reduces the aluminium content of the alloy so far that a critical aluminium concentration is not reached, no other protective aluminium oxide layer can be formed. This leads disadvantageously to a very rapid breakaway oxidation, and the destruction of the component. This effect is stronger at temperatures above 800° C. due to the fact that, often at this point, metastable Al2O3 modifications, especially θ- or γ-Al2O3, are formed instead of α-Al2O3 that is generally formed at high temperatures. The above-mentioned oxide modifications are disadvantageously characterised by significantly higher growth rates. The invention relates to methods whereby aluminium-containing alloys advantageously form an oxidic covering layer predominantly consisting of α-Al2O3, at a temperature higher than 800° C., especially in the initial stage of oxidation, and thus have a significantly improved long-term behaviour.

摘要:
A digital image in CMOS camera images is processed by first generating an output signal g from a CMOS camera. Then its spatio-temporal gradient (gx, gy, gt) is derived from the output signal. A time constant c and a local object shift (ux, uy) are established from prior knowledge. Finally a target signal value q is calculated from the output signal g as q=(gx*ux)+(gy*uy)+(g*−1*c)+gt.

The invention relates to a method for producing a layer structure comprising a strained layer on a substrate. The inventive method comprises the steps of producing a defect area in a layer adjoining the layer to be strained, and relaxing at least one layer adjoining the layer to be strained. The defect area is especially produced in the substrate. Additional layers can be epitactically grown. Layer structures so produced are especially suitable for producing various types of components.

A porous near-net-shape metallic parts with an open porosity of at least 10% by volume is made by first forming an injectable mass of a metallic powder of stainless steel, Ti, NiTi, or a titanium alloy, at least one thermoplastic binder, and at least one place holder. The mass then injection molded into the shape of the part to be produced, cooled, set in a capillary-active material, and subjected to a first-stage binder removal to produce an open porosity. The place holder is then removed at least partially from the part with a fluid, and the part is subjected to a thermal binder-removing process. Finally the part is sintered.
摘要:
MCrAl layers according to prior art often display chipping of the thermally grown aluminum oxide layer (TGO) as a result of thermally induced stresses, which significantly reduces the oxidation behavior or the bonding behavior of ceramic heat insulating layers. An inventive MCrAl layer is designed in such a way that the TGO created thereon is microporous and thus allows expansion. The microporosity of the TGO is ensured by adding elements into the MCrAl layer in a targeted manner.
