Abstract: FIELD: drying. 
     SUBSTANCE: invention relates to drying equipment and can be used in agricultural and other grain dryers with a gravitational moving layer, e.g., louver, column, etc. A method and apparatus for distributing gas in a louver-type shaft grain dryer consisting of a heated air chamber, a moist air chamber, a drying and cooling vertical chamber from modules installed one above the other forming a shaft, several narrow shafts are located in each module, with louvers located thereon from top to bottom in several rows, separated from each other and from the walls of the module by supply and discharge channels. According to the invention, the gas supplied to the supply channels near each louver is divided into three flows, wherein one of the flows passes through the under-louver slits, the second one - through the "shark gills"-type louvers located on the vertical sides of the louvers, and the third one - through the "shark gills"-type louvers located on the bent side of the louvers, wherein all three gas flows pass through the louver column and enter the discharge channels through opposing under-louver slits, "shark gills"-type louvers located on the bent and vertical sides of the louvers, respectively, while ensuring a uniform flow of the gas passing through the entire volume of the louver column. "Shark gills"-type louvers are additionally applied on the vertical and bent sides of the louvers over the entire surface or partially, on the vertical side the louvers are bent in the direction of the air flow, on the inclined side the louvers are bent in the direction of the grain flow, the "shark gills"-type louvers can have a length along the entire shaft, or be made intermittent, or be arranged staggering. 
     EFFECT: inventions provide a possibility to increase the specific gas supply throughout the entire volume of the drying or cooling chamber, intensify the drying process and increase the productivity, increase the homogeneity of grain drying and the quality.

Abstract: Изобретение относится к медицине, а именно к миниинвазивной хирургии печени. Проводят ультразвуковое исследование и определяют размеры гемангиомы. Если диаметр гемангиомы правой доли печени от 5 до 10 см, то пациенту проводят УЗИ с контрастированием и определяют время накопления контраста в ткани опухоли в артериальную фазу, время выведения из ткани опухоли в венозную и отсроченные фазы. Проводят артериоваскулярную эмболизацию. На следующий день после эмболизации проводят повторно УЗИ с контрастированием и определяют стагнацию артериального кровотока по сравнению с исходным. При стагнации 70% и более хирургический этап лечения считают завершенным. При стагнации от 30 до 70% и выполнении эмболизации спиральными эмболами выполняют радиочастотную термоабляцию, а в остальных случаях выполняют открытое резекционное вмешательство. Способ позволяет повысить эффективность лечения пациентов с гемангиомами печени, уменьшить частоту проведения открытых резекционных вмешательств и развитие серьёзных послеоперационных осложнений, снизить длительность пребывания в стационаре и летальность у данной категории больных. Способ позволяет повысить эффективность лечения пациентов с гемангиомами печени, прежде всего за счет применения при недостаточной стагнации кровотока по данным УЗИ исследования с контрастированием, выполненного на следующий день после артериоваскулярной эмболизации по сравнению с исходными значениями одного из современных миниинвазивных методов локальной деструкции, снизить, таким образом, необходимость открытых резекционных вмешательств, а соответственно, уменьшить количество послеоперационных осложнений, койко-дней в стационаре, летальность у данной категории больных. 3 пр., 5 ил.

Abstract: FIELD: railway transport. 
     SUBSTANCE: the threadless rail fastening contains an inverted U-shaped frame embedded in the sleeper, the inner upper part of which is inclined to the horizontal, inside which the end sections of the rod griffon are placed, and an under-rail gasket. The under-rail gasket is made in the form of a platform and consists of three bonded layers, of which the upper and lower layers are anti-friction and elastic, and the middle layer is polymer and protrudes beyond the sole of the rail to form two protrusions equal in height to the sole of the rail. The griffon end sections have a length greater than the depth of the frame, making it possible to move the griffon from the platform ledge to the sole of the rail. At the same time, the distance between the ends of the end sections and the rectilinear part of the griffon is less than the depth of the frame, which ensures the fixation of the structure. Inside the frame there is a corner connected to it, the horizontal shelf of which serves as a gasket between the griffon and the sleeper, and the vertical shelf is a stop for the ends of the griffon end sections. The embedded parts of the frame and the parts of the corner in contact with the sleeper are covered with an electrical insulating compound.
