Breakage parameters of some minerals and coals ground in a laboratory size ceramic mill
(NATL INST SCIENCE COMMUNICATION, 2003)
The kinetics of batch dry and wet grindings of calcite, barite, quartz, lignite and anthracite from feeds of sieve size 425+300 mum has been determined using a laboratory scale ceramic ball mill. The S-l values obtained ...
The effect of glass fiber distribution on the transverse strength and surface smoothness of two denture resins
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2003)
The aim of this study was to evaluate the effect of glass fiber distribution on the transverse strength and surface smoothness of conventional heat cured acrylic and autopolymerizing acrylic of an injection-molding system. ...

Purpose: To evaluate the short-term additive effects of latanoprost 0.005% and brimonidine 0.2%. Methods: This study was a randomized, double-masked, cross-over study that included 32 patients (32 eyes) with primary ...
The flashlamp-pumped pulsed dye laser (585 nm) treatment of hypertrophic scars in Asians
(LIPPINCOTT WILLIAMS & WILKINS, 2003)
Hypertrophic scars are common and cause functional and psychologic morbidity. Various treatment modalities have been advocated in the past, but the flashlamp-pumped pulsed-dye laser-585 nm (PDL) has been shown to be effective ...
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 ...
