Abstract: FIELD: pyrolysis.  
     SUBSTANCE: invention relates to a method for processing carbon-containing substances, which includes their pyrolysis processing in an installation by heating in a processing chamber to obtain a gaseous fuel as a pyrolysis product. Raw materials made in advance of an equal amount of sawdust, lignin and peat with a particle size of up to 3 mm are crushed using a shredder and loaded with a stream of compressed air into a fluidized bed furnace, where they undergo pyrolysis at a temperature of 600-800°C in two stages. At the first stage, the crushed raw material is sprayed with compressed air in a counter flow of pyrolysis gas heated to a temperature of 600-700°C, obtained above the grate of the fluidized bed, where the dispersed part of the raw material undergoes pyrolysis, and not the reacted part of the raw material enters the second stage, where on the grate of the fluidized bed at a temperature of 700-800°C in a fluidized bed, particles are crushed and interact with air supplied through the grate by a high-pressure fan, with the formation of pyrolysis gas. Pyrolysis gas from the fluidized bed furnace is fed into the gas collector, where it is cooled to a temperature of 100-105°C with sprayed water heated to a temperature of 90-95°C, and is directed by a gas blower into a gas holder for use by consumers. The particles of raw material caught in the gas collector brought by the pyrolysis gas are sent through the water seal to the sludge tank, where the particles of the raw material that have fallen through the furnace grate also enter, they are separated in a settling tank and, after dehydration in a spray dryer, are reused in the pyrolysis process. The invention also relates to an installation for the processing of carbonaceous substances, which contains a hopper for processed raw materials, a chamber for processing raw materials and a container for solid residue. The chamber for processing raw materials is made in the form of a fluidized bed furnace, divided into two parts by a grate and equipped with a loading device located above it, containing a shredder in the form of a two-roll screw and a branch pipe for supplying compressed air. The installation is equipped with a gas collector, a gas blower, a gas holder, a hot water tank, a sludge tank, a sump with a sludge removal mechanism, a sludge pump, a spray dryer, low and high pressure fans and a tank for solid residue in the form of a bunker of unreacted raw material particles. 
     EFFECT: increased percentage of processing of carbon-containing substances and decreased losses in the installation during their processing.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely to infectious diseases and phthisiology. A detailed clinical examination is carried out. The presence or absence of the following clinical manifestations is clarified: complaints of shortness of breath, weight loss, fever, the presence of splenomegaly. It’s also necessary to count stab neutrophils in the general blood test. Then the following calculation is carried out in accordance with the following formula: z=(-5.34338)+1.30818×(SOB)+1.83543×(WL)+1.82002×(S)+1.90303×(F)+(-0.011090)×(P1) where “SOB” is shortness of breath, “WL” is weight loss, “S” is splenomegaly, “F” – fever, “P1” is the percentage of stab neutrophils in the general blood test.  The sum (z) of the numerical values ​​of the signs is calculated. The values are multiplied by the discriminant coefficient of the signs: 1.30818 for shortness of breath, 1.83543 for weight loss, 1.82002 for splenomegaly, 1.90303 for fever, (-0.011090) for the numerical value of the percentage of stab neutrophils in the general blood test. After that the values are summed with a constant equal to (-5. 34338) followed by calculation using the original formula. The probability of an unfavorable outcome in a tuberculosis patient with HIV infection upon admission to the hospital of the Federal Penitentiary Service of the Russian Federation is calculated using the formula. If a probability value is 50% or higher, the risk of an unfavorable outcome and the need for hospitalization of the patient to the intensive care unit are predicted; if the probability value is below 50%, the patient is admitted to the hospital ward. 
     EFFECT: method makes it possible to determine the probability of an unfavorable outcome in a tuberculosis patient with HIV infection in a medical institution of the Federal Penitentiary Service of the Russian Federation (FSIN) by a limited number of clinical signs and one laboratory sign, which, individually and in combination, have high sensitivity and specificity.

Abstract: FIELD: engineering. 
     SUBSTANCE: invention relates to the field of destruction of a material solid body (MSB) by at least two sources of local highly intensive heat impact (LHIHI), forming an impact area consisting of figures selected from a group: a ring, a frame, assuming that the maximum concentration coefficient of thermoelastic stresses attributed to the interference of elastic waves in this area is achieved, and is aimed at providing effective modes of LHIHI sources on the surface of the MSB for destruction thereof, including technical apparatuses (TA), by reducing the ultimate tensile strength of the material of the solid body or reducing the load-bearing capacity of the structure of technical apparatuses made of metals, alloys, composite materials, as well as optical and optoelectronic apparatuses. Thermoelastic (thermal) stresses are a type of mechanical stress caused in the MSB by a change in the temperature or the unevenness of distribution thereof. Thermoelastic (thermal) stresses occur in the MSB due to the limited possibility of thermal expansion (compression) from the surrounding parts of the body or from other bodies surrounding the body. Thermoelastic (thermal) stresses can cause destruction of the MSB, parts and structural elements of the TA. LHIHI is understood as the impact of a heat flow source only on a certain (limited) part of the surface of the MSB in the form of a heat spot of various shapes, figures, and sizes. 
     EFFECT: provided effective modes of LHIHI sources on the surface of the MSB for destruction thereof.
