Abstract: The present invention relates to new marker sequences for neurodegenerative diseases and the diagnostic use thereof together with a method for screening of potential active substances for neurodegenerative diseases by means of these marker sequences. Furthermore, the invention relates to a diagnostic device containing such marker sequences for neurodegenerative diseases, in particular a protein biochip and the use thereof.

Abstract: The present invention relates to methods of detecting neurodegenerative diseases or disorders, particularly to methods for early detection of neurodegenerative diseases, such as Parkinson's disease. The present invention provides a method for detecting a neurodegenerative disease in a subject, the method comprising testing the subject for an indicator of release of neuromelanin from cells in the brain, wherein a positive test is indicative of death of brain cells containing neuromelanin and is characterised by an elevated level of the indicator of release of neuromelanin compared to control values.

Abstract: The invention relates to a method for establishing the neurologically relevant properties of a material, for which a nematode is used.

Abstract: The invention relates to a method for cleaning a metallic or an enameled surface comprising flooding a metallic surface contaminated with deposits with a mixture comprising (i) water, (ii) chippings of woods selected from the group consisting of merantis, bongossis, mahoganies, sipos, khayas, lauans, and sapellis, and (iii) a member selected from the group consisting of polyaspartic acid, salts of polyaspartic acid, and polysuccinimide, and thereby cleaning the surface.

Abstract: A method for cleaning surfaces with a mixture containing water and wood chippings, a specific mixture, and the use of said mixture as a cleaner.

Abstract: The present invention relates to cleaning compositions which, as powder or as aqueous formulation, comprise sodium bicarbonate and, as dispersants, polyaspartic acids and/or salts thereof, to the use of these cleaning compositions for the abrasive cleaning of hard surfaces, and also to a method of cleaning surfaces contaminated with deposits using these cleaning compositions.

Abstract: A method for cleaning a surface by flooding and thereby cleaning a surface contaminated with deposits with a mixture containing water, wood chippings, and optionally, polyaspartic acid or a derivative of a polyaspartic acid.

Abstract: In a device for automatically tracking a moving object, which device includes: an optical measuring head rotatable about vertical and horizontal axes, the measuring head having first and second light transmitters for producing and emitting, respectively, a horizontally and a vertically sharply collimated light beam along respective beam axes, the transmitters being operative to cyclically sweep the beam axes horizontally and vertically, respectively, over given ranges about zero positions, and an optical receiver mounted to receive light echoes generated by reflections of the transmitted beams and having an optical axis oriented parallel to the beam axes when at the zero positions.

Abstract: Apparatus for use with a system in which successive pulses, each composed of a train of high frequency oscillations, are emitted by a transmitting transducer, propagated through a transmission medium, and received by a receiving transducer having a given transient behavior, the apparatus serving to measure the time interval between reception of successive pulses by the receiver transducer and to prevent erroneous measurements resulting from propagation of the pulses over indirect paths through the transmission medium, prevention of erroneous measurements being achieved by effecting time interval measurements only with respect to those pulses for which the output signal from the receiving transducer in response to reception of each such pulse exceeds a selected threshold value during a predetermined time interval subsequent to passage of that output signal above a given comparison value which is less than the threshold value.

Abstract: An acoustic system for measuring the speed of flow or current speed of a body of water employing a measuring path through the water which extends from one shore to the other in a direction oblique to the direction of flow of the water. A triggerably measuring sound generator positioned on one shore transmits a pulse over the measuring path to a receiver on the other shore. The receiver produces an output which triggers the measuring sound generator to emit a subsequent pulse. A measuring circuit evaluates the resulting pulse repetition frequency of pulses emitted by the sound generator and produces an output proportional to the flow speed of the water.
