Voltammetric and drift spectroscopy investigation in dithiophosphinate-chalcopyrite system
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
The mechanism of dithiophosphinate (DTPI) adsorption on chalcopyrite was investigated by diffuse reflectance Fourier transformation (DRIFT) spectroscopy and by cyclic voltammetry (CV) at various pHs. CV experiments showed ...
Scaling properties of equilibrating semiconductor mounds of various initial shapes
(ELSEVIER SCIENCE BV, 2017)
A surface below its roughening temperature consisting of two dimensional concentric circular monoatomic steps is discussed under step-flow model. Entropic interactions between the steps are considered and the diffusion ...
The interaction of N2O with ZSM-5-type zeolites: A transient, multipulse investigation
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The interaction of N2O with MFI zeolites was investigated by a multipulse transient response method at 250 degrees C with subsequent temperature-programmed desorption. It was shown that the active sites for the formation ...
A new testing method for indirect determination of the unconfined compressive strength of rocks
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
A new testing method for the indirect determination of unconfined compressive strength (UCS) of rock core samples is presented. As known, there exist several methods for indirect estimation of UCS, such as point load index ...
On Prime and Semiprime Near-Rings with Generalized Derivation
(NATL INQUIRY SERVICES CENTRE PTY LTD, 2010)
Let N be a left near-ring and S be a nonempty subset of N. A mapping F from N to N is called commuting on S if [F(x),x] = 0 for all x S. The mapping F is called strong commutativity preserving (SCP) on S if [F(x),F(y)] = ...
Helicobacter pylori infection in mother and infant pairs in Anatolia
(AVES, 2010)
Background/aims: The aim of this prospective study was to determine the seroprevalence rates of Helicobacter pylori in mother and infant pairs and to discuss the possible fecal-oral transmission route of Helicobacter pylori ...
A case with Pyle type Metaphyseal Dysplasia: Clinical, radiological and histological evaluation
(MEDECINE ET HYGIENE, 2003)
A case with Pyle type Metaphyseal Dysplasia: clinical, radiological and histological evaluation: Pyle type metaphyseal dysplasia is a rare autosomal recessive disease that is primarily affect metaphyses. Here we present a ...
Microstructural Characterization and Thermal Properties of Aluminium Titanate/Spinel Ceramic Matrix Composites
(POLISH ACAD SCIENCES INST PHYSICS, 2014)
Spinel (MgAl2O4) ceramics possesses a high melting point, high hardness, a relatively low density, excellent transmittance, a high strength, a relatively low thermal expansion coefficient, high thermal shock resistance and ...
The Relationship Among the Level of Serum Amyloid A, High-Density Lipoprotein and Microalbuminuria in Patients With Familial Mediterranean Fever
(WILEY, 2016)
BackgroundSerum amyloid A (SAA), which is produced in the liver, acts as an apoprotein of high-density lipoprotein (HDL) accumulation in extracellular matrix of tissues and organs. SAA elevations play a significant role ...
Increased Irisin Concentrations in Patients with Crimean-Congo Hemorrhagic Fever
(NATL INST INFECTIOUS DISEASES, 2017)
Crimean -Congo Hemorrhagic Fever (CCHF) is a life-threatening viral infection. The pathogenesis of the disease is not well understood. The aim of this study was to determine the change in irisin concentrations in patients ...
