Granted: 2019-10-23
Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to catalysis and oil refining to versions of a method of preparing alumina metal-containing catalysts for processing hydrocarbon raw material based on aluminum oxide. Aluminum oxide-containing catalyst for processing hydrocarbon material is prepared from powder or paste of aluminum hydroxide, optionally in a mixture with a modifying additive, by adding a solution of a mineral and / or organic acid as a peptizing agent, molding the obtained mixture, optionally with neutralization of the molded granules with an ammonia solution, drying and calcining the molded granules at temperature of 500–650 °C, impregnation of cooled calcined carrier granules with a solution containing at least one compound of a metal and possibly chlorine, optionally in a solution of a mineral and / or organic acid, followed by drying and calcining the molded catalyst granules at temperature of 450–600 °C the catalyst prepared for the catalyst based on gamma-aluminum oxide can additionally contain 0.05–10.0 wt% of at least one of the following elements: tin, zirconium, titanium, lead, lanthanum, up to 1.5 % chlorine and 5–75 wt% of zeolite or ferroalumosilicate with structure ZSM-5 (MFI) or ZSM-11 (MEL). At that, in order to increase water-resistance of freshly prepared carrier granules or previously prepared by known methods of carrier granules before their impregnation with active components, the impregnated granules are held for 10–80 hours in a humid air atmosphere at atmospheric pressure and temperature of 15–35 °C. 
     EFFECT: implementation of the method reduces losses of both the carrier and active components which occur at the stage of preparation of the catalyst as a result of cracking of the molded granules of the carrier.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, particularly to orthopaedic dentistry, and is intended for use in complex jaw prosthesis of patients with extensive defects of maxillofacial tissues. Bone defect of upper jaw of patient is tightly covered with moist sterile tissues so that edges of defect remained open to depth of 5–10 mm. Impressions are taken from both jaws by alginate or silicone mass, according to which models from gypsum are moulded. Model of the upper jaw is installed on the platform of the vacuum apparatus and squeezed on it with a standard plate of silicone. Squeezed plate is removed from gypsum model of upper jaw, obturating part of plate is cut with scissors or cutter so that edges of plate overlap along entire perimeter of bone defect by 5 mm. Obturating plate in the form of a "hat with margins" is fitted in a bone defect of the upper jaw and an impression of the upper jaw is taken with an alginate or silicone mass. Impression is cast by gypsum, having removed from it a plate in the form of a "hat with fields". Further, a wax base with wax beads is made, central occlusion or central ratio of jaws, artificial teeth is determined. Fitting the wax structure of the prosthesis in the oral cavity, prosthesis polymerisation, treatment and polishing.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to ophthalmology. There are localized edema and its height with the help of optical coherent tomography and when obtaining an edema height value not exceeding 500 mcm according to optical coherence tomography. Edema zones are treated with a laser at wave length 532 nm. Laser power is selected in the area of the neuroepithelium edema, which is as far as possible from the foveolar avascular zone in the area of the vascular arcade. Laser coagulator Quantel Medical Supra with wave length 532 nm is used for application of laser applicators. Laser applicators are applied in micro-pulse mode with parameters: spot diameter of 100 mcm, porosity of 5 %, exposure of 0.1 s to weak reaction of retina in the form of easy whitening in laser application point. Then power is reduced to disappearance of retinal coagulation reaction. Further, the obtained power is used in laser treatment in a subthreshold microimpulsive mode of operation. At the first stage, the neuroepithelial edema zones are exposed to the non-capturing foveolar avascular zone of the selected laser power. In the foveolar avascular zone, power for laser exposure is reduced by 40–50 % of the selected one. Month after the laser treatment, a second stage of laser treatment is detected by means of optical coherent tomography of the macular edema. If observing a decrease in the height of the neuroepithelium edema by more than 50 mcm from the height of the edema at the beginning of the treatment, the laser treatment power used at the second stage is reduced by 50 % as compared to that in the first stage. If the edema height is reduced by less than 50 mcm, the power is reduced by 30 % and the zones of the detected residual neuroepithelial edema are treated. If the residual edema of the neuroepithelium covers the foveolar avascular area, the area is exposed to laser exposure with a power reduced by 30 % relative to the power of the laser exposure used to treat the foveolar avascular region at the first stage of treatment. 
     EFFECT: method enables to work in an edema zone located in a foveolar avascular region, and if observing a residual edema, laser treatment can be performed in several stages.
