The "law and finance theory" predicts that the common law system provides the best basis for financial development and economic growth, followed by Scandinavian and German origin civil law and finally French origin civil law. Referring to a number of sceptical views, this paper argues that the theory faces an identification problem, since the majority of common law countries have a market-based...

background: isolating sperms with normal chromatin content is considered vital in intra cytoplasmic sperm injection treatment. today, researchers are trying to find new procedures to select sperms with normal chromatin content and morphology. this study examines the effectiveness of zeta, density gradient centrifugation (pure sperm) and combination of pure- zeta procedures in selecting sperms w...

Since the electric motor of pure electric vehicle replaced the engine, the "masking effect" disappears, and the problem of vibration and noise of the transmission becomes prominent. This is generated during the gear meshing and is transmitted to the housing through the shaft and bearing. Thereby, radiation noise of the housing are generated. The prediction and analysis...

The conduct of perfusion has been described as ‘95% boredom and 5% panic.’ Now I cannot imagine many individuals ascribing to this gross underestimation of the challenges facing perfusionists today, but there are times in all of our practices, especially those centers who have embraced off-pump coronary artery revascularization, that these statistics seem a wee bit unwanting. As a past director...

The 2012 Albert Lasker Special Achievement Award in Medical Science will be shared by Donald Brown and Tom Maniatis for their scientific work leading to the purification and study of single genes by physical and molecular biological methodologies. Brown and Maniatis are also recognized for their extraordinary commitment and generosity in promoting the careers of young scientists. The impact of ...

pure rockfill dams have been found specific attention in watershed management and flood control, recently. in addition to hydraulic specific features, one of the important advantages of these structures is their consistency with nature and environment. normally, floods are accompanied with high sediment loads which may enter the body of dam. when flow through dam body governed by hydraulic grad...

In the long version of his Ph.D. thesis, Hugh Everett III developed pure wave mechanics as a way of solving the quantum measurement problem faced by the standard von Neumann-Dirac collapse formulation of quantum mechanics. Pure wave mechanics, however, encounters problems of its own. I will brief review Everett‟s description in his thesis of the standard measurement problem, how pure wave mecha...

This paper puts forward the view that the life-cycle model of system development has been allowed to make the transition from a useful intellectual tool for discussing specific aspects of the process to a definitive statement of what the process actually “is”. We argue that this hinders the discussion of Requirements Engineering in fundamental ways, and that challenges to the supremacy of this ...
