Abstract: A hot-film air-mass meter for measuring an air-mass flow which flows in the main direction of the flow, which can be used, in particular, in the intake tract of an internal combustion engine. The hot-film air-mass meter comprises a sensor chip having a measuring surface. The air-mass flow flows essentially parallel over one surface of the sensor chip. A flow separating element is mounted upstream from the measuring surface with respect to the main flow direction. The at least one flow separating element is designed in such a way that the air-mass flow is separated from the measuring surface of the sensor chip in at least one separation zone prior to reaching the measuring surface.

Abstract: A method for cleaning of a measuring element (1) passed over by a gas flow is arranged on a thin-walled membranous material (5). The measuring element (1) includes at least one heatable element (6, 7, 8; 10, 11), which is arranged on the membranous material, the membranous material being capable of vibrating. By means of a control apparatus (20) or a switching (22) associated with the measuring element, a periodic delivery of current (41, 42) in intervals takes place in this manner to at least one heatable element (6, 7, 8; 10, 11) of the measuring element (1) and thereby produces vibrations. Alternatively, vibrations of the membranous material (5) can be produced by special vibration exciters or by means of ultrasonic coupling.

Abstract: A drug composition for the prevention and the therapy of neurodegenerative diseases (for example ischemic or hemorrhagic stroke, focal and global ischemia, amyotrophic lateral slerosis (ALS), Alzheimer's disease, Parkinson's disease, Hunntington's disease, multiple sclerosis). The combination of effective agents comprises at least two of the following substances: &agr;-lipoic acid; ambroxol and one or several inhibitor(s) of the angiotensin-converting enzyme (ACE). It could surprisingly be found in the experiments on which the invention is based that neuronal cells which are particularly sensitive to degenerative insults, have less free constitutional thiol groups than have other cells of the central nervous system (CNS). It was demonstrated that this reduced content of free thiol groups is causally connected to the damaging of those cells after a degenerative event.

Abstract: A method and device for analyzing and quantifying flows for the three-dimensional determination of flow velocity components or the visualization of flows in fluids or gases. An illuminating device generates electromagnetic radiation of a predefined color to scan a detection space in the form of light planes arranged spatially one behind the other that are at least roughly parallel, and that are generated temporally one after the other. As a result, electromagnetic waves are generated in the detection space by particles characterizing the flow, and are detected using at least one image detector which records two-dimensional color images. The frequency, frequency spectrum, and/or intensity detected by at the least one of the image detectors is changed by an as a function of time.
