Abstract: FIELD: combating radio-electronic means. 
     SUBSTANCE: invention relates to the technique of combating radio-electronic means; it can be used for radio suppression of radar stations (radars). Said method is based on the formation of a microwave radiation stream with a carrier frequency within the range of operating frequencies of the probed radar and recording the response of the reflected signal. In this case, the microwave radiation stream is formed in the form of a sequence of pulses, the amplitude of which is increased from pulse to pulse according to a linear law. Next, the amplitude of the received pulse is measured and the correspondence of the law of change of its amplitude to the linear law is determined. If the law of change differs from the linear law, the suppression is carried out by continuous microwave radiation with a power corresponding to the amplitude of this pulse. 
     EFFECT: increase in electromagnetic compatibility with its own radio-electronic means, achieved by determining the moment of occurrence of the required suppression efficiency and further suppression with constant power.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to pulmonology, cardiology and respiratory sleep medicine. LVDD is diagnosed in patient with apnea-hypopnea by questioning patients and night printing. Indices of apnea-hypopnea index are specified, according to Epworth sleepiness scale, minimum night saturation and saturation time less than 90%. Then, using the formula given by us: z=20.55237+(-0.043966)×(A)+0.7923×(E)+(-0.43599)×(S)+0.080403×(T), where "A" is an apnea-hypopnea index (events per hour), "E" is a number of Epworth sleepiness scores, "S" is minimum night saturation (%), "T" is saturation time less than 90% (% of total sleep time), calculating sum (z) of numerical values of features multiplied by discriminant coefficient of feature (-0.043966 for index of apnea-hypopnea, 0.7923 for number of points on scale of Epworth sleepiness, (-0.43599) for minimum night saturation, 0.080403 for saturation time less than 90%), and summed with constant equal to 20.55237. Considering logistic function of type 
     
       
     
     it is possible to calculate LVDD probability in patient with apnea-hypopnea by known formula (source: Hosmer David W., Stanley Lemeshow (2000). Applied Logistic Repression. 2nd ed New York; Chichester, Wiley. ISBN 0-471-35632-8) 
     
       
     
     where e is the base of the natural logarithm = 2.71828947 ..., z is the sum of the numerical values of each of the features. Thus, LVDD is obtained in the patient with apnea-hypopnea by the value of which the risk of cardiovascular complications is predicted. If probability is 50% or more, the LVDD risk in the apnea-hypopnea patient is predicted, followed by developing cardiovascular complications; if the probability is less than 50%, the LVDD risk in the apnea hypopnea patient is low. 
     EFFECT: invention provides a method for determining the probability of left ventricular diastolic dysfunction (LVDD) in a patient with apnea-hypopnea by a limited number of clinical signs, having separate and combined high sensitivity and specificity.

The essence of the invention is the creation of a more economical filter spillway on a ground dam with a shield. On a ground dam, which includes a body of water-permeable material (stone, pebbles, crushed stone) and an anti-filtration shield, hollow reinforced concrete boxes without a bottom are placed behind the shield at a level of the calculated water level WL in a reservoir, vertical walls of which, facing upstream, are not solid, but have holes - slots with a total area of at least 40% of the total wall area, and from above, boxes are covered with a reinforced concrete slab with a parapet, which serves as a dam crest and has a mark of the maximum water level WL. These walls with slots are a water intake of the filter spillway. Hollow reinforced concrete boxes are installed on the section of the filter spillway, and on remaining sections of the dam, the anti-filtration shield is raised along a slope to the maximum water level mark, and a parapet with a height of up to the crest of the ground dam is placed on it. On a dam base, within the lower part of the lower slope, in the area of the filtration flow outlet into the downstream, a stone prism is poured out of the rock mass, the top of which is higher than the calculated water level in the downstream, when the maximum flood is passed, and the slope of the lower slope of the prism and the size of the stone are selected in such a way that to ensure a safe outlet of the filtration flow into the downstream.  
     EFFECT: safe passage of flood flow by passing water through the filter spillway, reducing the volume of reinforced concrete structures and construction and installation works, and reducing the cost of the dam as a whole.

Device consists of a closed housing combined with a reflector, inside which there is a source of bactericidal radiation in the form of a mercury discharge lamp, fan for blowing the cleaned air through the internal volume of the housing, the ignition mode control device and the operation of the bactericidal radiation source, wiring accessories for mounting and connecting a bactericidal radiation source to a device for controlling the mode of ignition and operation of the bactericidal radiation source. Recirculator is made in the form of a closed reflector, made with possibility of simultaneously performing functions of a protective housing and an air-conducting channel for disinfected air, from polished anodized aluminum with high coefficient of directed reflection in ultraviolet bactericidal region of radiation, and structurally is made of four coaxial equivalent sectors. Coordinates of points of the reflecting surface of each sector are determined by expressions for coordinate points: X=R*CosA+R*A*SinA, Y=R*SinA-R*A*CosA, Y=R*{CosA*(1-A)+SinA*(1+A)}-X, where: R is the radius of the sweep circle, structurally selected from the condition: R is greater than or equal to the radius of a circle circumscribed around the bactericidal radiation source, A is the angle orienting the corresponding radius vectors, radians. Bactericidal recirculator is made in such a way that the ultraviolet rays emanating from the bactericidal radiation source, after the primary reflection from the reflector, repeatedly fall on the active surface of the reflector, are again reflected, and so forth, excluding uncontrolled falling and their absorption by the bactericidal radiation source and other structural elements of the bactericidal recirculator. Bactericidal recirculator is configured to create a reflector of high volumetric density of the bactericidal radiation flux in the volume of the irradiation chamber, which exceeds the density of the direct radiation flux generated by the bactericidal radiation source itself.
