The modification of aluminium content of natural zeolites with different composition
(ELSEVIER SCIENCE BV, 2019)
A series of natural zeolites with different compositions were modified by formation of hydrated aluminium oxide onto the zeolite structure after NaOH treatment of the natural zeolites. Natural and modified zeolites were ...
Response of some chickpea (Cicer arietinum L.) genotypes to salt stress conditions
(WFL PUBL, 2012)
The salt (NaCl) tolerance of 5 chickpea genotypes was investigated. Plants were grown in 5 different NaCl concentrations. Germination percentage, shoot and root length, shoot and root dry weight and salt tolerance percentage ...
Hemorheological parameters in patients with fibromyalgia syndrome
(IOS PRESS, 2017)
AIM: To evaluate hemorheological parameters in patients with fibromyalgia syndrome (FMS) in order to elucidate the etiology of the disease. METHODS: Twenty-three adult FMS patients and 20 healthy controls were enrolled in ...
Molecular modeling study on the relative stabilities of the flotation products for arsenic-containing minerals: dixanthogens and arsenic(III) xanthates
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The interactions of As(III) ion with C2H5OCS2- and C2H5SCS2-, known as the most popular collector ions, were studied by density functional theory (DFT) at the B3LYP/6-31G** level in connection with the arsenic-containing ...
Effects of magnetic field, hydrostatic pressure and temperature on the nonlinear optical properties in symmetric double semi-V-shaped quantum well
(SPRINGER, 2016)
In this work, the effects of magnetic field, hydrostatic pressure and temperature on the linear and nonlinear optical properties in GaAs/AlxGa1-xAs symmetric double semi-V-shaped quantum well (DSVQWs) have been theoretically ...
Rare earth double sulfates from pre-concentrated bastnasite
(ELSEVIER SCIENCE BV, 2008)
A mixture of rare earth double sulfates was produced from a Turkish bastnasite-containing pre-concentrate (low grade concentrate) by sulfuric acid baking, subsequent water leaching and precipitation with sodium sulfate. ...
Pullback mode dragline stripping in dipping coal seam
(IMPERIAL COLLEGE PRESS, 2002)
This study presents the results of a computer-based model developed for analysing the pit geometry formed when a dragline operates in pullback mode. Basically, three spoiling procedures are modelled for a flat or an inclined ...
The creative training in the visual arts education
(ELSEVIER SCI LTD, 2016)
The main purpose of this study was to examine the effect of creative training on creative thinking and problem solving of students in visual arts higher education. The participants were Turkish university students. The ...
Assessment of Cardiac Functions in Fetuses of Gestational Diabetic Mothers
(SPRINGER, 2014)
We investigated cardiac function in 67 fetuses of gestational diabetic mothers (FGDMs) and 122 fetuses of healthy mothers between 24 and 36 weeks of gestation. Cardiac functions were evaluated by M-mode, pulsed-wave, and ...
Effect of ketanserin administration on intraocular pressure
(KARGER, 2001)
Purpose: We evaluated the effect of oral single-dose (20 mg) ketanserin on intraocular pressure (IOP) in normotensive and hypertensive eyes. Methods: This study included 15 healthy volunteers and 16 patients with ocular ...
