BACKGROUND/AIMS Although the National Kidney Disease Education Program recommends use of the modification of diet in renal disease (MDRD) formula to estimate the glomerular filtration rate (GFR), most drug-dosing recommendations and clinical practices employ the Cockcroft-Gault (CG) formula. The quality score of the original MDRD study was better than that of the original CG study, although the...

A voltage multiplier rectenna is a combination of rectifier and an antenna used for the conversion AC to DC. It essential part system RF energy harvesting. Conventional rectennas are characterized by low efficiency. This study presents analytical novel mode designed harvesting systems current output stages efficiency optimization. The design contains rectification circuit with seven stages. Sch...

introduction: we intended to assess the accuracy of re-expressed modification of diet for renal disease (mdrd) and cockcroft-gault (cg) equations to estimate glomerular filtration rate (gfr) in chronic kidney disease in two different etiologies of acute renal failure (arf): acute tubular necrosis (atn) and acute glomerulonephritis (agn). methods: patients admitted for arf or the patients compl...

As part of our fusion product-diagnostic development program, we have begun a series of experiments with 14 MeV neutrons generated in a Cockcroft-Walton accelerator. Two different detectors have been used to measure the neutron yield: a silicon SBD and a Cu foil. The energy of the emitted neutrons has been determined by using two spectrometers: the SBD and a 3 He proportional counter. The react...

Background. The limitations of the laboratory evaluations of kidney function (KF) are well recognized. Therefore, in clinical practice, various mathematical formulas are applied for the bedside estimation of KF. Aim. The aim of this study was to compare the calculated KF function derived from two different formulas i.e. the Cockcroft-Gault (CG) formula and the shorten version of Modification of...

This paper includes a Cockcroft-Walton (CW) high phase dc-dc voltage transition based on multiplier, with no step-up transformer. The suggested conversion approach is very appropriate for low-input dc generating systems continuous input current switch, diode or condenser low rib, and voltage. In this article two frequencies in the control techniques are used, one works order to reduce inductor ...
