The objectives of this study were to determine the mechanical work, the power output, and the angular kinematics of the lower limb and the linear kinematics of the barbell during the first and second pulls in the snatch lift event of the 2010 Women's World Weightlifting Championship, an Olympic qualifying competition, and to compare the snatch performances of the women weightlifters to those re...

The focus of this paper is the study of direct alternating-current (ac)–ac converters, beginning by buck, halfbridge, full-bridge, and push–pull converters. From the basic converters, we apply a simple methodology to make the use of switches in commercial configurations possible. Following that, eight voltage restorers supplied either on the line side or on the load side are proposed. A compara...

F or gauging inflationary pressures, many policymakers and financial market analysts pay close attention to the behavior of wages. It is widely believed that if wage costs rise faster than productivity, the price level may rise as firms pass forward increased wage costs in the form of higher product prices. Hence changes in productivity-adjusted wages1 are believed to be a leading indicator of ...

The rapid pace of change in modern medicine makes training on simulation platforms an absolute necessity. With the microprocessors the sophistication of simulators exploded. More recently medicine has developed simulators that are becoming increasingly sophisticated, especially in anesthesia training but also to train intensive care personnel. This is an area that will rapidly advance in the fu...

We present a simple and generic theoretical description of actinbased motility, where polymerization of filaments maintains propulsion. The dynamics is driven by polymerization kinetics at the filaments’ free ends, crosslinking of the actin network, attachment and detachment of filaments to the obstacle interface and entropic forces. We show that spontaneous oscillations in the velocity emerge ...

The most important mission of sociology is perhaps to push forward the production of society. Sociologists should not only in its theory, but also in its practice, help resist the pressure from the state and the market, on the one hand, and assist society to emerge and grow, on the other. In facing the problem of the production of society, sociologists must strive for a transition from a sociol...

Migration of Health workers has devastating consequences leading to loss of health workers in the nation of origin. This research was carried out to identify the push factors related to migration of Nurses from Nepal to other developed countries. A cross sectional descriptive study was conducted via different social medias. The data was collected from 67 migrated Nepalese Nurses to: Australia, ...

We prove that a particular pushing-blocks puzzle is intractable in 2D, improving an earlier result that established intractability in 3D [OS99]. The puzzle, inspired by the game PushPush, consists of unit square blocks on an integer lattice. An agent may push blocks (but never pull them) in attempting to move between given start and goal positions. In the PushPush version, the agent can only pu...

The present paper examines secular trends of homicide rates by means of a systematic re-analysis of all available quantitative studies on pre-modern homicide. The results confirm, first, that homicide rates have declined in Europe over several centuries. Second, the empirical evidence shows, that unequivocal decline began in the early seventeenth century. Third, the data indicate that the secul...

Mexican immigrants were historically clustered in a few cities, mainly in California and Texas. During the past 15 years, however, arrivals from Mexico established sizeable immigrant communities in many “new” cities. We explore the causes and consequences of the widening geographic diffusion of Mexican immigrants. A combination of demand-pull and supply push factors explains most of the inter-c...
