Abstract: The invention relates to medicine and concerns a photosensitizer for detecting and curing tumors. The inventive photosensitizer is embodied in the form of a composition containing chlorin in the form of salt and alkali metals. The chlorin is composed of 80-90% of chlorin e6, 5-20 of purpurin 5 and the rest being purpurin 18-chlorin p6. Said photosensitizer is produced by extracting Spirulina biomass with the aid of acetone. Afterwards said biomass is exposed to acid treatment, neutralization, hydrolysis, extraction of pheophorbide a, dissolution in acetone, addition of a strong base, neutralization and reprecipitation of chlorin e6.

Abstract: The present invention relates to a method for playing a lottery game and for a sports-game totaliser. According to this method, each player (3) participating e.g. in a lottery uses an individual memory device (4) that comprises at least a timer (27), a memory (26), an information input-output device (29) as well as an indicator (31) defining a game area (89) corresponding to that found on lottery tickets of the “bingo” or “national lottery” type. This system is further characterised in that, when counting the time for recording hypothetical information into the individual memory device (4), it uses both the digital data from the timer (27) and the time characteristics thereof. The individual memory device (4) is further capable of recording simultaneously several variants of hypothetical information and of formatting the same using a predetermined algorithm.

Abstract: An aerodynamic lifting-thrusting propulsion device has a frame with an axis, relative to which the frame is arranged with a possibility of rotation, a cardan joint having a cross, at least two aerodynamic surfaces, each of which is mounted on the cardan joint with a possibility of oscillations synchronously with a rotation of the frame, a rod mounted on the frame, the cardan joint being connected with the rod, the cross of the cardan joint having axes which are mutually perpendicular and located correspondingly in mutually perpendicular planes intersecting along an axis of the rod, one of the axes of the cross extending through an axis of rotation and an axis of the rod, the rod being arranged parallel to an axis of the frame, the axis of the frame being connected with each of the aerodynamic surfaces by a mechanical transmission providing a rotation of the aerodynamic surface synchronously and opposite to a rotation of the frame.

Abstract: The invention relates to optical instruments. There are provided a method for inspection of an analyzed surface and a scanning analyzer for inspection of defects on the surface. The method comprises the steps of rotating an object with the analyzed surface about a first center of rotation; forming a light spot on the analyzed surface; and sensing separately a light mirror-reflected and a light scattered from the analyzed surface at the incidence point of the light spot; and detecting surface defects by analyzing the produced signals. To implement the method, a surface scanning analyzer moves the light spot relative to the analyzed surface through an arc about a second center of rotation which lies outside the analyzed surface; and detects defects on the surface of wafers by measuring the magnitude of the scattered light. The reduced size and cost of the measurement device enables its integration into manufacturing equipment for inspection of semiconductor wafers in electronic industry.

Abstract: The invention relates to the field of medicine, in particular, to ophthalmology. The technical result of the invention is reduction of the loss of endothelium in the post-operation period, and during post-operation keratopathy and the initial stage of secondary endothelium-epithelium dystrophy—reduction of the edema and normalization of the thickness of the cornea. The technical result is achieved in that in a method of restoring the endothelium of the cornea, including administration of an activating solution into the anterior segment of the eye, in accordance with the invention, restoration of the endothelium of the cornea is effected with the aid of an activating solution having the following composition: carnosine  0.1-20.0 mg a complex of glycosaminoglycans with cations 0.005-0.

Abstract: The inventive apparatus for transosseous osteosynthesis comprises a detachable repositioning mechanism for axial compression and distraction of bone fragments, the mechanism having a thrust element with two guiding bars. A mobile traverse is mounted on the guiding bars. A lead screw which interacts with a screw orifice of the mobile traverse is fixed in the thrust element. Two side bars for movement of bracing frames, one end of each of the side bars being fixed to the mobile traverse, the other end being fixed to a holder with the aid of a screw clamp. The apparatus has at least two holders, each comprising a hollow body with an inner cylindrical surface, the axis of the body coincides with the axis of a corresponding tightening bolt, and also has a stem on the side surface of the body with an opening, which stem has a threaded portion. A latch is disposed in the holder body and is intended for fixing the holder in the direction of axial movement along the tightening bolt.

Abstract: In order to lower the painfulness of injection of the remedy containing the products of lignin basic hydrolysis and oxidation, pyrophosphate, NaCl and water the value of pH of the remedy is adjusted to a neutral one by the addition of HCl.
