Abstract: A compressor (1) has a cast compressor casing (2) with an inlet port (3) oriented in an axial direction (AR), an intake chamber (4) with an impeller, a volute (5) and a pressure port (6) connected consecutively. The volute (5) orbits the intake chamber (4) and the pressure port (6) extends tangentially outwards from the volute (5). In the compressor casing (2), an air recirculation duct (7) has a suction-side duct (12) and pressure-side duct (13), which is connected to the inlet port (3) at a pressure connection point (13a) downstream of the impeller and downstream of a tongue formed by the volute (5) on an outer wall of the pressure connection (6) facing the volute. The suction-side duct (12) is connected to the inlet port (3) at a suction connection point (12a) upstream of the impeller.

Abstract: In some examples, a non-transitory machine readable storage medium has machine readable instructions to cause a computer processor to segment a datastream into a plurality of equal length blocks each of which has a fixed length, separately encrypt each equal length block using a first encryption key, swap a subset of bits of a first encrypted equal length block with a subset of bits of a second encrypted equal length block such that both of the blocks each have a length equal to the fixed length, and separately encrypt each block using a second encryption key.

Abstract: A method of making an optochemical sensor, the method comprising: providing a reflective substrate having a major surface; affixing a detection layer comprising at least one intrinsically microporous polymer to at least a portion of the major surface; depositing a substantially continuous semi-reflective metallic layer on at least a portion of the detection layer, the semi-reflective metallic layer comprising palladium and having a network of fine irregular cracks therein; and heating the detection layer and semi-reflective metallic layer in the presence of molecular oxygen at a temperature sufficient to cause the cracks to widen. Sensors prepared according to method are also disclosed.

Abstract: Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing photoinitiator groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.

Abstract: The invention provides a method of detecting myocardial ischemia in a human or a non-human body, said method comprising administering to said body a physiologically acceptable manganese complex or salt thereof, subjecting said body to a magnetic resonance imaging procedure capable of generating images with time intervals of less than 0.5 seconds and thereafter providing a series of images of the myocardium of said body whereby to identify regions of abnormal blood flow. The method in accordance with the invention is of use not only in detecting myocardial ischemia, but also in discriminating between reversibly and irreversibly injured myocardial tissues, thereby providing important information about myocardial viability, e.g. during or following a severe heart attack or coronary occlusion. The method of the invention also provides an effective means of monitoring reperfusion of the myocardium.

Abstract: An in vivo diagnostic method for differentiating normal from diseased tissue is described, using diffusion-weighted magnetic resonance imaging (MRI). Differences in molecular diffusion between viable and necrotic tissue, and normal and diseased tissue, are measured using diffusion-weighted MRI techniques to evaluate the success of a medical treatment regimen.
