A first line of cellular defense against many viruses, including those causing AIDS, is activation of an intracellular biochemical system termed the 2'-5' oligoadenylate/RNase L pathway. It is well known that this pathway malfunctions in individuals with progressive AIDs-related immune dysfunction, but the mechanism of malfunction remained obscure. An inhibitor substance, released in HIV infected ...

A machine dishwashing process characterised in that a highly concentrated aqueous cleaning formulation is sprayed onto at least partially soiled articles and, after a contact time, the cleaning formulation and soil are removed in one or more subsequent stages is disclosed. A dishwashing machine characterised in that it is adapted to effect such a process is also disclosed. Improved results, for ex...

A device and method for detecting and measuring the concentration of a substance in a sample by optoacoustic spectroscopy in which light of selected discrete frequencies is directed onto the sample and the acoustic response of the sample is detected. The frequencies are selected according to the optoacoustic spectrum of the substance under test to distinguish that substance from others. A laser (6...

This invention relates to glass (1,4) carrying an electroconductive coating (7) and, in particular, to a method of applying bus bars (3,6) on the glass (1,4) to establish electrical contact with the coating (7) and to coated glass (1,4) provided with bus bars (3,6) in accordance with the invention. The method of applying the bus bars (3,6) to the electroconductive coating (7) involves arc spraying...

A piston unit (27) is movable forwards and backwards in the inner cylinder chambers (28) and is operable by means of a thrust rod. The inner cylinder (26) has top inlet apertures (32) for fluid intake to the upper part (29) of the cylinder chamber (28). At the bottom of the inner cylinder are outlet apertures (40) for outflow of fluid from a separate lower part (30) of the cylinder chamber to the ...

Impulses from the rotor blades (2) give rise to signals when the blades pass indicators (4, 5). The signals are detected and are used to calculate the blade angles. The rotor (1) is formed as a running wheel for a hydraulic machine, and the signals are received by at least two indicators located in the running wheel chamber wall (3) in a plane parallel to the wheel axis or in a plane parallel to t...
