Optimum dragline selection for strip coal mines
(INST MINING METALLURGY, 1998)
A model is presented by means of which the optimal dragline selection may be made. An outline is given of the methodology that was adopted in developing a series of generic algorithms to first define and then formularize ...
Investigation of acid sites on V2O5/Nb2O5 catalysts by FTIR
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1995)
In this study the V2O5/Nb2O5 catalysts were prepared using grafting and impregnation techniques. Both the V2O5/Nb2O5 prepared catalysts and the adsorption of pyridine on V2O5/Nb2O5 have been studied with FTIR spectroscopy. ...
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 ...
Effects of intravenous anesthetic agents on pregnant myometrium
(POLISH ACAD SCIENCES INST PHARMACOLOGY, 1999)
Emergent or elective surgical procedures under general anesthesia may be required during pregnancy for some patients. For this reason, effects of anesthetics on uterine contractions are important. General anesthesia is not ...
SELECTIVE-INHIBITION OF ENDOTHELIUM-DEPENDENT RELAXATION BY SYMPATHECTOMY IN RABBIT CAROTID-ARTERY RINGS INVITRO
(J R PROUS SA, 1993)
The influence of cervical and periarterial sympathectomy on endothelium-dependent relaxation of the rabbit common carotid artery was studied in vitro. Noradrenaline, serotonin, acetylcholine and papaverine concentration-response ...
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 ...
On the spectrum of the Rhaly operators on c(0) and c
(INDIAN NAT SCI ACAD, 1998)
In this paper, we determine the spectrum of the Rhaly matrix R-a as an operator on the spaces c(0) and c, when lim(n) (n + l)a(n) not equal 0 and exists.
