Abstract: FIELD: measurement technology. SUBSTANCE: invention is related to processes of measurement of loss in layer of deposit formed on working surface of capacitive detectors of level or humidity used in various branches of industry, specifically, in heat power industry to control level of oil water in crude oil and fuel oil or moisture content in crude oil and fuel oil. Electrodes are coated with layer of insulation. Value of capacitance is converted to voltage of signals of variable frequency. Temperature and level of medium are measured. Voltage of output signals in absence of deposit, voltage of output signals in presence of deposit and voltage of output signal with detector being switched off are measured depending on level of medium at various temperatures. Value of relative loss in insulation coat free of layer of deposit and value of relative loss in insulation coat with layer of deposit are found on basis of obtained results.

Abstract: FIELD: nuclear power engineering; helium-cooled high-temperature reactors. 
     SUBSTANCE: proposed reactor has graphite blocks with channels accommodating fuel microelements. These channels are made in the form of coaxial annular cavities holding loosely charged fuel microelements. Layer of fuel microelements charged in cavities is rather thick for resonance neutrons, that is product of this layer thickness by mean uranium density in layer should range between 2.5 and 5 g/cm 2 . Gaseous coolant vent holes are radially disposed and passed through cavity charged with fuel microelements. Coolant is effectively stirred within headers which eliminates nonuniformity in coolant heating upon respective passage through layer of fuel microelements. Proposed reactor design enables raising heterogeneity of its core. Such heterogeneous core needs lower enrichment of uranium, smaller amount of graphite, and greater uranium charge. Fuel microelement layer has relatively small amount of graphite and can be made sufficiently thick for resonance neutrons. 
     EFFECT: enhanced heterogeneity and reduced size of reactor core.

Abstract: FIELD: medicine, gynecology. 
     SUBSTANCE: in pregnant women one should detect the capacity of blood leukocytes to produce γ-interferon, detect antibodies to γ-interferon and autoantibodies to OBM and S-100 proteins. At decreased production of γ-interferon being below 16 IU/ml, autoantibodies to OBM and S-100 being below (-) 40 c.u. for each parameter and increased value of antibodies to γ-interferon being above 20 c.u. one should predict perinatal pathology. The method suggested requires no surgical interference to obtain spinal fluid. Modern application of adequate curative-prophylactic measures in pregnant women with predicted perinatal pathology enables to reduce the frequency of severe forms of intrauterine infection from 26.7% to 11.9%; the frequency of perinatal pathology of infectious nature from 25.2% to 13.3%.
