Correlation of the breakage parameters with the critical surface tension for wetting of barite
(ELSEVIER SCIENCE SA, 2003)
In this paper, we present a correlation and experimental data for a relationship between the breakage and the wettability for barite mineral. The breakage parameters, which are readily obtained from grinding test, are the ...
Investigation of coal and ash recovery and entrainment in flotation
(ELSEVIER SCIENCE BV, 2003)
This paper discusses the effect of particle size, impeller speed and pulp density on flotation and entrainment of coal and associated gangue, consisting mostly of kaolinite and illite. Experimental work indicated that ...
In vitro antibacterial, antifungal, and antioxidant activities of the essential oil and methanol extracts of herbal parts and callus cultures of Satureja hortensis L.
(AMER CHEMICAL SOC, 2003)
The present study was designated to evaluate the antimicrobial and antioxidant activities of the essential oil, obtained by using a Clevenger distillation apparatus, water soluble (polar) and water insoluble (nonpolar) ...
Urethral duplication
(OKAYAMA UNIV MED SCHOOL, 2003)
Urethral duplication is a rare congenital anomaly. Although a number of theories have been proposed to describe the embryology of the condition, the actual mechanism of the disorder is still unclear. We report here a case ...
Optical transitions in quantum well wires under intense laser radiation
(ELSEVIER SCIENCE BV, 2003)
The influence of a laser-field on the exciton binding energy and interband optical transitions in quantum-well wires is calculated by using a variational method and in the effective mass approximation. We conclude that in ...
Adsorption of BSA onto radiation-crosslinked poly(AAm/HPMA/MA) terpolymers
(SPRINGER-VERLAG, 2003)
The terpolymeric poly(acrylaDaide/2-hydroxypropylmethacrylate/maleic acid) (AAm/ BPMA/MA) hydrogels in the rod form have been prepared by gamma-radiation of quaternary mixtures of acrylamide, 2-hydroxy propylmethacrylate, ...
Water sorption, solubility and dimensional changes of denture base polymers reinforced with short glass fibers
(SAGE PUBLICATIONS LTD, 2003)
The aim of this study was to determine water sorption, solubility and dimensional stability of injection and compression-molded polymethyl methacrylate based denture base polymer that was reinforced with various concentrations ...
Predictors of outcome after in situ anterior vaginal wall sling surgery
(SPRINGER-VERLAG LONDON LTD, 2003)
Pubovaginal sling procedures are being performed with increased frequency for stress urinary incontinence. The vaginal wall sling was introduced in 1989 by Raz et al., and its success rate has been reported as being 61%-100%. ...
Syntheses and characterization of maleic anhydride-styrene-allyl propionate terpolymer ester derivatives
(JOHN WILEY & SONS INC, 2003)
In this study, maleic anhydride (MA)-styrene (St)-allyl propionate (AP) was produced with MA, St, and AP. It was then reacted with n-propyl alcohol (Pr), n-butyl alcohol (Bu), n-pentyl alcohol (Pn), and benzyl alcohol (Bz) ...
High-concentration tramadol-induced vasodilation in rabbit aorta is mediated by both endothelium-dependent and -independent mechanisms
(SHANGHAI INST MATERIA MEDICA, 2003)
Aim: The mechanism of tramadol-induced vasodilation was investigated using isolated rabbit thoracic aortic rings. Methods: Aortic rings from 8 rabbits were placed in organ bath and precontracted with phenylephrine (10(-5) ...
