ADSORPTIONS OF SOME HEAVY-METAL IONS IN AQUEOUS-SOLUTIONS BY ACRYLAMIDE MALEIC-ACID HYDROGELS
(MARCEL DEKKER INC, 1995)
In this study, acrylamide-maleic acid (AAm/MA) hydrogels in the form of rod have been prepared by gamma-radiation. They have been used for adsorption of some heavy metal ions such as uranium, iron, and copper. For the ...
Tolerance to isosorbide dinitrate in isolated strips of rabbit corpus cavernosum
(BLACKWELL SCIENCE LTD, 1998)
The aim of this study was to investigate whether prolonged exposure to a high concentration of isosorbide dinitrate (ISDN) would result in tolerance being developed against its relaxant activity in strips of corpus cavernosum, ...
SULFUR ISOTOPE STUDY OF SOURCE AND DEPOSITS OF STIBNITE IN THE TURHAL AREA, TURKEY
(SPRINGER VERLAG, 1991)
The Turhal antimony sulfide ore deposits are hosted by a Permain-Jurassic sequence which consists of black phyllites at the base followed by interbedded phyllites and calcareous quartzites with metabasite interlayers and ...
Improvement in intersubband optical absorption and the effects of device parameter variations in quantum wells with an applied electric field
(ACADEMIC PRESS LTD, 1999)
The intersubband optical absorption in symmetric and asymmetric, single and coupled, double GaAs/Ga1-xAlxAs quantum wells is calculated. The results have been obtained in the presence of a uniform electric field as a ...
POSTOPERATIVE RETENTION OF URINE IN GENERAL SURGICAL PATIENTS
(TAYLOR & FRANCIS AS, 1993)
Objective: To find out the incidence of retention of urine after various general surgical operations, and to assess the effects of applying a bag filled with warm water (40-45-degrees-C), and encouraging early mobilisation ...
THERMAL-DEGRADATION OF BLENDS OF PVC WITH POLY(TETRAMETHYLENE SEBACATE)
(ELSEVIER SCI LTD, 1991)
The thermal degradation of PVC-PTMS blends has been studied over the whole composition range, using thermal volatilisation analysis and thermogravimetry. In the TVA studies, degradation products have been separated and ...
PALEOMAGNETIC STUDY OF BLOCK ROTATIONS IN THE NIKSAR OVERLAP REGION OF THE NORTH ANATOLIAN FAULT ZONE, CENTRAL TURKEY
(ELSEVIER SCIENCE BV, 1995)
This palaeomagnetic study investigates crustal deformation within, and adjacent to, the Niksar overlap area of the North Anatolian Fault Zone (NAFZ) in central-east Turkey. The studied rock formations comprise: (1) red ...
Impaired contraction and relaxation in the aorta of streptozotocin-diabetic rats
(KARGER, 1998)
It is known that diabetes mellitus alters the vascular responsiveness to several vasoconstrictors and vasodilators. Endothelium-derived nitric oxide is a potent endogenous nitrovasodilator, and endothelin-1 (ET-1) is a ...
GEOLOGICAL SETTING, PETROGRAPHIC AND GEOCHEMICAL CHARACTERISTICS OF THE CRETACEOUS AND TERTIARY IGNEOUS ROCKS IN THE HEKIMHAN HASANCELEBI AREA, NORTH-WEST MALATYA, TURKEY
(JOHN WILEY & SONS LTD, 1993)
Upper Cretaceous to Tertiary igneous rocks outcrop in the Hekimhan-Hasancelebi area, about 80 km to the north-west of Malatya, Central-Eastern Anatolia. These igneous rocks consist of Maastrichtian Bahcedam volcanics, the ...
The electronic structure of a quantum well under an applied electric field
(ACADEMIC PRESS LTD, 1996)
The effects of an applied electric field on quantum well subband energies are calculated variationally within the effective mass approximation for model potential profiles. The concept of a quasi-bound state is examined ...
