Abstract Turbocharging has been demonstrated as a key technology to enhance fuel efficiency in the automotive field that faces increasingly stringent emission regulations. Due reciprocating engine, pulsating flow feds turbocharger turbine, which experiences conditions far from continuous scenario. In this work, effects of characteristics mass pulse, parameterized through amplitude, frequency, a...

Theoretical models play an important role in the design of engine control and diagnostic systems, allowing to reduce development time and costs. The paper describes a control-oriented theoretical model for the simulation of an automotive Diesel engine built up using a “simulation library” developed in Simulink environment. Library blocks, defined for engine components and subsystems, were assem...

In this work, a microfluidic chip-based valveless flow injection analysis (FIA) system with gravity-driven flows and liquid-core waveguide (LCW) spectrometric detection was developed. Automated sample injection in the 0.3-6.4 nL range under gated injection mode was achieved by controlling the vertical position of the waste reservoir fixed on a moving platform and the residence time of the reser...

Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...

Abstract Plastic is omnipresent in the current global scenario and it difficult to get rid of completely. Therefore, a strategic plan essential recycle plastic waste. According United Nations Environment Programme report, 400 million tons single-use waste gets generated globally on an annual basis, which amounts 47 % total Out this huge volume, only 9% recycled worldwide. In India, 9,400 either...
