An approach to design a dragline pit in pullback stripping method
(A.A. Balkema, Rotterdam, Netherlands, 1998)
A simulation model is developed to optimize dragline selection for surface mines with one flat-lying coal seam where pullback stripping is applied. Recognizing that a dragline that runs in round-the-clock fashion is the ...
Malignant chondroid syringoma: A case report
Malignant sweat gland tumors are very rare form of primary tumors of the skin appendage. In this group, malignant chondroid syringoma is the least common variety. Till 1991, less than twenty cases have been reported. We ...
Inhibitory effects of isradipine on spontaneous and oxytocin- and carbachol-stimulated contractions of rat myometrium
Our aim was to investigate the effect of isradipine, a second-generation calcium channel blocker, on spontaneous and oxytocin- and carbachol-stimulated contractions of myometrium isolated from nonpregnant and pregnant rats. ...
Removal of some cationic dyes from aqueous solutions by acrylamide/itaconic acid hydrogels
(KLUWER ACADEMIC PUBL, 1998)
Acrylamide/itaconic acid (AAm/IA) hydrogels prepared by irradiating with gamma radiating were used in experiments on the uptake of some cationic dyes such as basic red 5 (BR-5), basic violet 3 (BV-3) and brilliant cresyl ...
Tectonostratigraphic relationships between the North Anatolian Thrust Zone (NATZ), and the Kirsehir Massif to the north of Sivas (Turkey)
(Elsevier Masson SAS, 1998)
In Central Anatolia, to the north of Sivas, the remains of the Northern Neotethyan domain crops out in a system of south verging thrust slices intercalated between the Eurasiatic margin (Tokat Massif), and the Taurus. In ...
Subband structure and excitonic binding of graded GaAs/Ga1-xAlxAs quantum wells under an electric field
(ACADEMIC PRESS LTD, 1998)
The effects of an applied electric field on subband energies and excitonic binding for a graded GaAlAs quantum well are calculated variationally within the effective mass approximation. The very sensitive dependence of ...
