The New Semi-Experimental Method for Simulation of Turbine Flow Meters Rotation in the Transitional Flow
The new semi-experimental method for simulation of the turbine flow meters rotation in the transitional flow has been developed. The method is based on the experimentally established exponential low of changing of dimensionless relative turbine gas meter rotation frequency and meter inertia time constant. For experimental evaluation of the meter time constant special facility has been developed. The facility ensures instant switching of turbine meter under test from one channel to the other channel with different flow rate and measuring the meter response. The developed method can be used for evaluation and predication of the turbine meters response and dynamic error in the transitional flow with any arbitrary law of flow rate changing. The examples of the method application are presented. Keywords—Dynamic error, pulsing flow, numerical simulation, response, turbine gas meters.
ANALYSIS OF NONLINEARITY OF THE TURBINE GAS METERS TIME CONSTANT DURING STEP RESPONSE
The step response of the turbine gas meter has been studied experimentally. Using the specially developed method the turbine gas meter rotation inertia time constant during step response has been evaluated. It has been found that the time constant depends not only on the final value of flow rate, but also on the current rotation frequency of the meter rotors. The results can be used for calculating the dynamic error of different types of tachometric meters with pulsing flow rate. DOI: http://dx.doi.org/10.5755/j01.mech.19.5.5544
Deviant Women: Female Crime and Criminology in Revolutionary Russia, 1880-1930
This title examines the position of women in early Soviet society through the lens of deviance. After seizing power in 1917, the Bolsheviks initiated reforms aimed at abolishing the old way of life in Russia. A new Family Code liberalized marriage procedures, promoted communal living arrangements, and abolished the concept of illegitimacy. Other decrees legalized abortion, deregulated prostitution, and emancipated women. The Bolsheviks' Marxist ideology that guided these reforms was also behind the assertion that crime, an artifact of bourgeois capitalist exploitation, would disappear under socialism. As crime persisted, Soviet criminologists - a cohort of jurists, doctors, sociologists, anthropologists, psychiatrists, statisticians, and forensic experts - were charged with examining its causes and motives to determine the most effective methods to eliminate it. The problem of female crime occupied a prominent position in criminologists' studies. In explaining 'traditional' female crimes of the domestic sphere - infanticide, spouse murder, and petty theft, among others - criminologists pointed to the offenders' backwardness and ignorance, material circumstances, and even biology. Kowalsky examines the position of women in early Soviet society through the lens of deviance, exploring how Soviet criminologists understood female crime and how their attitudes helped shape the development of Soviet social and behavioral norms. "Deviant Women" looks at the emergence of criminology in early Soviet Russia, tracing the development of principles and theories - in particular of female deviance - and highlighting the ways in which criminologists were able to conduct innovative social science research under the constraints of Bolshevik ideology. Kowalsky then focuses on the analyses of female crime and criminologists' attitudes concerning sexuality, geography, and class. Concluding with a close study of infanticide, the most 'typical' crime committed by women, Kowalsky discusses the social attitudes that were revealed in the professional discussion of this crime. Historians of modern Russia and the USSR, scholars of gender studies, and those studying criminology will be fascinated by this original study.
