Title: Method for surgical treatment of idiopathic epiretinal fibrosis with preservation of foveal fragment of internal limiting membrane
Inventor: Kolesnik Svetlana Valerevna
IPC: A61F9/007
Filed: 2019-03-28
Granted: 2019-12-05
Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For the surgical treatment of the idiopathic epiretinal membrane (iERM), three-port chromovistrectomy is carried out using a Triamcinolone acetonide dye, contrasting epiretinal membrane with dye membrane blue 0.15 %, removal of epiretinal membrane, contrasting of internal limiting membrane (ILM). Using endovitreal tweezers, the ILM is gripped by pinch 2–3 mm from the lower temporal arcade, and a flap is formed, the ILM is separated in the direction of the fovea center, not 1.0–2.0 mm to the fovea zone. Then the direction of ILM separation is changed and the flap is drawn along an arch of an imaginary circle of diameter 5 mm as circular maculorexis, leaving an intact foveal fragment of ILM 2.5–3.5 mm in diameter. Operation is terminated by removing the ports. 
     EFFECT: method provides eliminating retinal tractions, reducing traumatism of the surgical intervention, preserving the anatomical profile of the fovea region, faster achieving maximum visual acuity, reducing the rehabilitation period and improving the quality of vision of the patients.

Abstract: FIELD: chemistry. 
     SUBSTANCE: invention relates to chemistry and specifically to a method of producing hydrogen and elemental sulfur via decomposition of hydrogen sulfide and can be used to purify gas emissions from hydrogen sulfide. Method comprises passing initial hydrogen sulfide-containing gas through a fixed layer of a granular solid chemisorbent capable of adsorbing hydrogen sulfide with formation of hydrogen and solid sulfur-containing compounds on the surface of the chemosorbent, extraction of hydrogen from the obtained gas stream and periodic regeneration of the layer by decomposition of sulfur-containing compounds and extraction of elementary sulfur vapor at high temperature with subsequent condensation of sulfur vapors at low temperature. Method comprises not less than two parallel reactors containing chemisorbent layers, wherein in each of reactors chemisorption mode is alternated with supply of initial hydrogen sulfide-containing gas with temperature from -30 to 100 °C and regeneration mode with supply of regenerating gas not containing hydrogen, with temperature of 500–700 °C in the opposite direction, performing transition from chemisorption mode to regeneration mode with chemisorbent temperature reduction below preset value in range of 150–250 °C at point of layer of chemisorbent, distant from entry point of hydrogen sulfide-containing gas at distance from 30 to 60 % of height of layer. 
     EFFECT: invention ensures complete decomposition of hydrogen sulfide in continuous mode with considerable reduction of temperature of initial hydrogen sulfide-containing gas, simplification of equipment for implementation of the method, including its heat-exchange infrastructure, reduction of power consumption, as well as possibility of processing of hydrogen sulfide-containing gases without preliminary treatment.

Abstract: FIELD: textile industry.  
     SUBSTANCE: invention relates to the textile industry, in particular to thick-walled seamless casings intended for use as reinforcing elements of articles made of composite materials. The method for forming a multilayer woven casing consists in its production from weft yarns and systems of warp yarns on a forming mandrel installed in a circular weaving machine. Alternating layers of warp and weft threads carry out rectangular reinforcement, respectively, in the direction of the generatrix and the annular direction of the casing, forming the fell of the cloth in the course of its production. At the same time, the connection of the layers of warp and weft threads for the entire thickness of the casing is performed by three systems of dressing threads. Moreover, the laying of each of them at the fell of the cloth is carried out in such a way that they alternately separate adjacent weft rows. At the same time, when laying each next weft in a row, the system of dressing threads moves at the fell of the cloth by only one layer.  
     EFFECT: invention makes it possible to reduce the breakage of the dressing threads, as well as to reduce the formation of loops of the dressing threads.
