Multi-objective optimization of some process parameters of a lab-scale thickener using grey relational analysis
(ELSEVIER SCIENCE BV, 2012)
This paper presents a novel effective method for the optimization of some operating parameters of a laboratory scale thickener on the dewatering performance with multiple performance characteristics based on the grey ...
Removal of UO22+ from Aqueous Solutions by Maleic Anhydride-Styrene-vinyl acetate Terpolymer Modified with Ethylenediamine and Diethylenetriamine
(ASIAN JOURNAL OF CHEMISTRY, 2013)
Maleic anhydride-styrene-vinyl acetate (MA-S-VA) terpolymer was prepared. It was modified by ethylenediamine (EDA) and diethylenetriamine (DETA) in order to get cross-linked polymers bearing carboxyl and amine groups. They ...
Shallow donor impurities in different shaped double quantum wells under the electric field
(WILEY-V C H VERLAG GMBH, 2004)
The binding energy of the donor impurity in double triangle quantum well (DTQW), double graded (DGQW) and double square (DSQW) GaAs-(Ga,Al)As quantum wells under the electric field is calculated by using a variational ...
Dobutamine Tc-99m furifosmin SPECT in detection of coronary artery disease: Evaluation of same day, rest-stress protocol
(JAPANESE SOCIETY NUCLEAR MEDICINE, 2003)
The purpose of this study was to evaluate the feasibility and diagnostic accuracy of same day reststress myocardial perfusion SPECT (MP SPECT) protocol by using technetium-99m (Tc-99m) furifosmin in conjunction with ...
N-[2-(4-Bromophenyl)-5-methyl-4-oxo-1,3-thiazolidin-3-yl]pyridine-3-carboxamide
(INT UNION CRYSTALLOGRAPHY, 2011)
In the title compound, C16H14BrN3O2S, the atoms of the 1,3-thiazolidine group, except for the N and the C atoms attached to the bromobenzene ring, are disordered over two sets of sites with occupancies of 0.605 (13) and ...
Immunohistochemical profile of CD markers in experimental neural tube defect
(TAYLOR & FRANCIS LTD, not define)
Neural tube defects (NTDs) are the second most common birth defects worldwide. Stem cells play a critical role in the mechanisms underlying NTDs. We established an experimental NTD model in rats using retinoic acid (RA). ...
Adsorption of some basic dyes by acrylamide-maleic acid hydrogels
(MARCEL DEKKER INC, 1996)
In this study, acrylamide-maleic acid (AAm/MA) hydrogels containing different quantities of maleic acid have been irradiated with gamma-radiation. They have been used in experiments on swelling, diffusion, and the adsorption ...
Ethyl 2-(9-methylsulfonyl-1-oxo-2,3,4,9-tetrahydro-1H-carbazol-2-yl)acetate
(BLACKWELL PUBLISHING, 2007)
The title compound, C17H19NO5S, crystallizes with two molecules per asymmetric unit; these do not exhibit the same pattern of hydrogen bonds. The indole part of the carbazole skeleton is almost planar, while the cyclohexenone ...
Ion pair vortex assisted-ionic liquid based dispersive liquid-liquid microextraction for selective separation and preconcentration of 4-methylimidazole from caramel colour drinks and foodstuffs prior to its spectrophotometric determination
(ELSEVIER SCIENCE BV, 2019)
In the study, a simple, fast, easy to use, cost-effective and green analytical method was developed for the selective extraction and determination of 4-methylimidazole (4-MeI) from caramel colored drinks and foods by using ...
Nimodipine can diminish oxidative stress in patients with severe head trauma
(EDIZIONI MINERVA MEDICA, 2012)
Aim. Antioxidative effect of nimodipine was investigated in patient with severe head trauma. Methods. The patients in group A were treated according to the standard procedures without nimodipine. Other patients in group B ...
