Abstract: A component for high-temperature use comprises a metallic base material and a non-ferromagnetic protective layer arranged thereon, which is able to form a protective oxide layer on the component surface at temperatures between 600° C. and 1100° C. A sensor material is introduced into the protective layer, wherein, in the stated temperature range, the local magnetism, notably ferromagnetism or ferrimagnetism, at the site of the sensor material is dependent on the local concentration and/or composition of the material of the protective layer in the immediate vicinity of the sensor material and/or on the cumulative temperature-time curve at the site of the sensor material. The component can be examined non-destructively, from the outside, for the local magnetism in the protective layer, which is typically between 100 ?m and 500 ?m thick.

Abstract: Large quantities of explosive hydrogen-oxygen mixtures can be produced by leaks or accidents in technical plants, e.g. nuclear reactors. The invention relates to a catalyst, a catalyst system, an arrangement for recombining hydrogen with oxygen, and a method for producing a catalyst. The inventive catalyst is characterized in that the ignition point of the mixture is exceeded under no circumstances even though the catalyst works in a strictly passive manner without outside intervention and the recombination is an exothermal reaction. The basic idea is to design the catalyst such that the catalyst autonomously limits the activity thereof in accordance with the prevailing temperature.

Abstract: The invention relates to a method for the topographical presentation of structural alterations in an examined brain using volume data records. In line with the invention, this method is distinguished in that functional areas are mapped by extracting profiles, where the profiles record boundaries for two functional areas in the examined brain, in that the boundaries of the two functional areas are recorded by calculating a multivariant distance measurement, and in that a microstructure in the region of the boundaries of the two cortical areas is recorded and is compared with at least one microstructure in a boundary region of a reference brain. To increase the comparability of various areas in various brains taking into account the interindividual variability, it is expedient for the volume data records to be transformed to a target volume data record using an elastic registration method.

Abstract: Disclosed is a method for positron emission tomography and to a PET scanner. The positron emission tomography method employs the following steps: a) two photons are emitted in opposite directions by an annihilation event in the sample, b) at least two of a plurality of detectors arranged around the sample are prompted to output a signal by the two photons, c) a signal line on which the event may have taken place is determined from the location of the detectors which have output a signal, d) this signal line is evaluated in the tomographic reconstruction of the sample, wherein for each event a plurality of signal lines are determined and evaluated in the tomographic reconstruction of the sample. As described at the outset, the reconstructed image thus becomes more accurate and noise is reduced. The method and the apparatus can improve the signal-to-noise ratio of images.

Abstract: Disclosed is an apparatus for application of a magnetic field to a sample, in particular an elongated sample. At least in places, the apparatus has magnetic bodies which are arranged such that they can rotate with respect to one another and have, and leave open, a common access opening for the sample. In particular, this allows the apparatus to be applied to an elongated sample whose ends are not accessible. As a result of the bodies being arranged such that they can rotate with respect to one another, the magnetic fields of the bodies can be adjusted with respect to one another before the apparatus is opened and closed, so as to minimize the magnetic field in the common access opening. In consequence, only small magnetic interaction forces need be overcome during opening and closing.

The generation of the first and second stimuli optionally occurs in a first or in a second operating mode, and the controller actuates the first and the second stimulation units such that in the first operating mode the generation of at least 60% of the second stimuli is chronologically coupled to the generation of the first stimuli, and in the second operating mode the generation of at least 60% of the second stimuli is carried out without generating the first stimuli.

Abstract: A device for decoupling and/or desynchronizing neural, pathologically synchronous brain activity, in which, the activities in a partial region of a brain area or a functionally associated brain area are stimulated by means of an electrode, resulting in decoupling and desynchronizing the affected neuron population from the pathological area and suppression of the symptoms in a patient. In an alternative embodiment of the device, the pathologically synchronous brain activity due to the disease is desynchronized which also leads to the symptoms being suppressed. The device has a stimulation electrode and at least one sensor which are driven by a control system in such a manner that they produce decoupling and/or desynchronization in their local environment.
