background quality of health services is one of the most important factors for delivery of these services. regarding the importance and vital role of quality in the health sector, a concept known as “clinical governance” (cg) has been introduced into the health area which aims to enhance quality of health services. thus, this study aimed to assess private and public hospitals’ readiness to impl...
A chelating resin coupling Amberlite XAD-2 functionalized with dithizone is synthesized and characterized. Dissolved cadmium is field-preconcentrated using a minicolumn packed with the synthesized resin and determined by flame atomic absorption spectrometry. Five experimental variables are evaluated. The enrichment factor of 416 is obtained for 50 mL of sampling volume, and the detection limit ...
corporate governance (cg) is an important effort to ensure accountability and responsibility and is a set of principles, which should be incorporated into every part of the organization. this study focused on the state of corporate governance (cg) in two categories of the banking industries: conventional banks and islamic banks. as conventional banks and islamic banks differ a great deal in the...
Sir: The enzymatic mechanism of resistance to aminoglycoside antibiotics has been explored by UMEZAWA.1,2) Many clinically isolated strains of aminoglycosides-resistant bacteria produce enzymes which phosphorylate, adenylylate or acetylate specific positions of aminoglycoside antibiotics. Kanamycin and kanamycin B are inactivated by aminoglycoside 3'-phosphotransferases, 2"-nucleotidyltransfera...
An ion-exchange process was developed for the separation of spectrographically pure praseodymium salts in kilogram amounts from commercially available concentrates. The application of either 0.5% or 0.1% citrate solutions as eluting agents was show to result in excellent separations of praseodymium from samarium, neodymium, and lanthanum when the mixed rare earths were eluted from Amberlite IR-...
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...
In this paper, the influence of Al2024 and Al5083 aluminum alloy coarse grains on mechanical properties and fracture mechanism of Al5083-B4C tri-modal composite has been discussed. Al5083 alloy powders with 5 wt. % of boron carbide were milled for 36 hours and 25 and 50 wt. % of coarse grain (CG) Al2024 and Al5083 powders were added to the milled powders and then hot press under argon atmospher...
