This article deals with problems related to the integration of reverse logistics activities within an organization and to the coordination of this new system. Reverse logistics activities refer to the recovery and processing of unused products and to the redistribution of reusable materials. For better control and management of these activities, new approaches and information support system are...

The improvement in reverse recovery of power NPN bipolar transistor (BJT) through incorporation of ‘‘universal contact’’ in the base is studied in detail. It is shown that use of universal contact allows redistribution of base current in saturation from collector region where recombination lifetime is high to extrinsic base region where effective recombination lifetime is low. The reverse recov...

UNLABELLED This study analyzed the incidence and clinical significance of reverse redistribution (RR) on stress-redistribution (201)Tl SPECT studies in patients with poor left ventricular function and tested the hypothesis that the RR phenomenon could be caused by artifacts. METHODS Seventy-three consecutive patients with chronic coronary artery disease and left ventricular dysfunction (eject...

This paper investigates causal relations between economic growth, income inequality, and transmission channels during the period 1972 to 2016. These channels include saving rate, investment rate, redistribution policies, human capital, and conspicuous consumption. There is no strong evidence that supports uni-directional or bi-directional causality. In addition, some of the transmission channel...

structural health monitoring of cracked structures is one of beloved subject of researchers recently. consider of crack behavior in the water and energy pipeline is important because of environmental problems. in this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. for this purpose, three- dimensional parametric model of cracked ...

despite the mythology that the global economy with its trade rules creates a ‘level playing field,’ international trade has never involved ‘level players.’ the inequalities in outcomes generated by the more powerful winning more frequently has led to innovative ideas for ex post redistribution to make the matches between the players both fairer, and in the analogy to basketball used by the auth...

4 Optimal HIV-1 suppression often is difficult to achieve and maintain with currently available antiretroviral drugs, and viral resistance eventually emerges to many drugs. Chronic antiretroviral therapy is also associated with complications such as body fat redistribution, hypertriglyceridemia and hypercholesterolemia, abnormal glucose metabolism, lactic acidosis, pancreatitis, avascular necro...
