Cristobalite formation from thermal treatment of Texas lignite fly ash
(ELSEVIER SCI LTD, 1999)
Texas lignite fly ash has been thermally treated at 1000-1200 degrees C in air, and the products analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). ...
Selective shear flocculation of chromite from chromite-serpentine mixtures
(ELSEVIER SCIENCE BV, 1998)
In this study, shear flocculation of chromite from mixtures of chromite and serpentine was investigated. The effects of zeta potential, contact angle, stirrer speed, flocculation (stirring) time, settling time and concentration ...
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 ...
The effect of aspirin, ticlopidine and their low-dose combination on platelet aggregability in acute ischemic stroke: a short duration follow-up study
(LIPPINCOTT WILLIAMS & WILKINS, 1999)
We investigated the effects of aspirin (300 mg/d), ticlopidine (500 mg/d) and their low-dose combination (aspirin 100 mg/d plus ticlopidine 250 mg/d) on the platelet aggregability using the Wu and Hoak method. Each treatment ...
Cationic dye adsorption by acrylamide itaconic acid hydrogels in aqueous solutions
(JOHN WILEY & SONS LTD, 1997)
Acrylamide/itaconic acid (AAm/IA) hydrogels containing different quantifies of itaconic acid have been irradiated with gamma radiation. The hydrogels were used in an experiment concerning the adsorption of cationic dyes ...
THERMAL-DEGRADATION OF GAMMA-IRRADIATED POLY(VINYL ACETATE)
(ELSEVIER SCI LTD, 1993)
The thermal degradation (TG) of poly(vinyl acetate) irradiated with gamma-rays has been investigated by dynamic thermogravimetry in a nitrogen atmosphere. The overall effect of irradiation is to render poly(vinyl acetate) ...
Effect of endothelin-1 on spontaneous contractions and effects of nimodipine and isradipine on endothelin-1-induced contractions in myometrial strips isolated from normal pregnant and preeclamptic women
(MUNKSGAARD INT PUBL LTD, 1998)
Background. To examine the effect of endothelin-l (ET-1) on spontaneous contractile activity and the effects of nimodipine and isradipine on ET-l-induced contractile responses in myometrial strips isolated from normal ...
Geology, base-precious metal concentration and genesis of the silica-carbonate alteration (listwaenites) from late Cretaceous ophiolitic melanges at central east Turkey
(GUSTAV FISCHER VERLAG, 1999)
The late Cretaceous (pre Maastrichtian) alteration of serpentinite bodies in the Divrigi and Kuluncak ophiolitic melanges has formed two distinct types of listwaenite. The earliest is silica-carbonate listwaenite (type I), ...
Kinematics of late pliocene-quaternary normal faulting in the southeastern end of the Gediz graben, Western Anatolia, Turkey
(V H WINSTON & SON INC, 1998)
The kinematic analysis of fault-slip data obtained from lower Pliocene and Pleistocene deposits indicates two successive extensional events in the southeastern end of the Gediz graben. The late Pliocene N-S extensional ...
Effect of conjunctival structure and inflammatory cell counts on intraocular pressure after trabeculectomy
(KARGER, 1999)
Purpose: To evaluate the conjunctival structure and inflammatory cell counts and to determine the predictive value of these histological parameters for postoperative intraocular pressure (IOP) levels after trabeculectomy. ...
