Abstract: FIELD: selective short-circuit protection of forked electric circuits. 
     SUBSTANCE: proposed system designed, in particular, to protect low-voltage power installations of up to 1000 V against short-circuit currents incorporating K number of time gradings starting reading from power supply has instantaneously-tripping circuit breakers at last K grading and selective circuit breakers with releases at gradings from first to (K - 1) one which have definite adjustable current settings in region of short-circuit currents; selectivity characteristic of release in the range of short-circuits between I sc.1  and I sc2  affords a number of fixed off-operation time delays (t sc o  = const) and at circuit currents higher than setting value of I sc2  release is operating instantaneously (t sc o  = 0). In addition, current-limiting reactors are connected to terminals of selective circuit breakers starting from that of second time grading. Reactances Z n  of these reactors are chosen so as to ensure that maximal short-circuit current past reactor I r(n)  would amount to (20 - 40)-fold rated current I n  of circuit breaker of given n time grading. I sc2  setting of each selective circuit breaker disposed at time grading from second to (K - 1), inclusive, amounts to (1.1 - 1.5) of maximal current I r(n)  at reactor output terminals. Newly introduced in releases of all selective circuit breakers is adjustable off-operation integral setting Q sc  whose value for circuit breakers of n time grading Q sc(n)  depends on off-operation integral Q o(n + 1)  of circuit breaker disposed at lower time grading (n + 1) maximal for this very time grading in short-circuit protection proceeding from equation Q n  = (1.5 - 2)Q (o(n+1) . 
     EFFECT: enhanced speed of response, reduced probability of heat loads on cables and other parts of installation caused by arcing current, enhanced reliability of protective gear, and reduced fire probability in installation.

Abstract: FIELD: medicine. 
     SUBSTANCE: method involves determining patient acetylation phenotype and predicting disease from table data built in advance. The table has morbidity coefficients for predicting diseases under prognosis and mortality rates caused by the diseases in groups of countries where rapid acetylators are predominant in more than 50% of population and in countries where slow acetylators are predominant in more than 50% of population in various age-specific life intervals. Prognosed diseases risks and lethal outcome risks caused by those diseases in given age intervals are determined from the values of the coefficients. The risks are predicted in the cases when said coefficient values corresponding to patient phenotype and sex are greater than the same coefficients of opposite phenotype of the same sex with authenticity level equal to or less than 0.05. Clinical course severity is additionally estimated in said age intervals depending on patient phenotype. Acetylation degree is taken into consideration.

Abstract: Способ определения изменений напряженно-деформированного состояния (НДС) земной коры относится к области исследования геодеформационных процессов гидрогеодинамическими методами и может быть использовано в сейсмопрогностических наблюдениях. Сущность изобретения состоит в том, что для использования более высокой тензочувствительности проницаемости горных пород по сравнению с их объемными деформациями предлагается сопоставлять временные ряды синхронных почасовых измерений атмосферных давлений и уровней воды в скважинах на контролируемой территории и по изменениям функций отклика уровней воды на баровариации оценивать изменчивость НДС земной коры. Для этого предлагаются следующие шаги: 1) гармонический анализ в скользящем временном окне шириной в 1 месяц и шагом в 1 сутки временных рядов почасовых синхронных наблюдений атмосферного давления и уровня воды в каждой скважине; 2) выделение устойчивых гармоник в наблюдениях атмосферного давления; 3) выделение когерентных им гармоник в наблюдениях уровней воды в каждой скважине; 4) определение относительных амплитуд отклика (ОАО) и времен запаздывания отклика (ВЗО) из сопоставления амплитуд и фаз найденных когерентных гармоник и составление их временных рядов с суточной дискретизацией для каждой скважины; 5) выделение в полученных временных рядах полумесячных и месячных приливных гармоник; 6) сопоставление их с теоретическими полумесячными и месячными приливными волнами в деформациях M f  и М m  (для определения тензочувствительности ОАО и ВЗО); 7) определение по текущим значениям ОАО и ВЗО изменений НДС земной коры. Техническим результатом является то, что способ позволит использовать высокую чувствительность проницаемости горных пород к деформациям для индикации последних и тем самым существенно повысить информативность пьезометрических наблюдений для оценки сейсмической опасности.
