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 ...
Mesoaxial complete syndactyly and synostosis with hypoplastic thumbs: an unusual combination or homozygous expression of syndactyly type I?
(BRITISH MED JOURNAL PUBL GROUP, 1998)
Syndactyly type I is an autosomal dominant condition with complete or partial webbing between the third and fourth fingers or the second and third toes or both. We report here a previously undescribed phenotype of severe ...
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 ...
EFFECTS OF PROPOFOL ON VASCULAR SMOOTH-MUSCLE FUNCTION IN ISOLATED RAT AORTA
(J R PROUS SA, 1994)
This study was undertaken to determine the direct actions of propofol, and whether propofol exerts any action on basal endothelium-derived relaxing factor release and vasodilator effect of acetylcholine on phenylephrine-induced ...
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) ...
Influence of some crosslinkers on the swelling of acrylamide crotonic acid hydrogels
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1997)
Acrylamide-crotonic acid hydrogels in the form of rods are prepared by gamma-irradiation of quaternary mixtures of acrylamide-crotonic acid-crosslinker-water with 2.6 and 5.2 kGy gamma-rays. The influence of the applied ...
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 ...
