The variation of electronic properties with the doping concentration of modulation-doped AlxGa1-xAs-GaAs double quantum wells
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007)
In this paper we have calculated the sub-band structure and the confinement potential of modulation-doped Ga1-xAlxAs-GaAs double quantum wells as a function of the doping concentration. The electronic properties of this ...
Treatment of metal containing wastewaters by natural zeolites
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2004)
In this study, removal of heavy metals in synthetic and wastewaters was studied by using natural zeolite, clinoptilolite. The activated and non-activated zeolites used were crushed and grinded to sizes between 1.0-2.0 mm. ...
The efficacy of ultrasonography in hemodynamically stable children with blunt abdominal trauma: a prospective comparison with computed
(ELSEVIER SCI IRELAND LTD, 2004)
Purpose: In this prospective study we aimed to investigate the diagnostic value of ultrasonography (US) in hemodynamically stable children after blunt abdominal trauma (BAT) using computed tomography (CT) as the gold ...
Variation of critical surface tension for wetting of minerals with roughness determined by Surtronic 3(+) instrument
(ELSEVIER SCIENCE BV, 2004)
This paper presents a correlation found between the surface roughness and critical surface tension of wetting of calcite and barite minerals. The minerals were ground in ball, rod and autogenous mills to collect samples ...
Factors affecting the oil agglomeration of sivas-divrigi Ulucayir lignite
(TAYLOR & FRANCIS INC, 2007)
In the coal industry, the coal particles need to be decreased to a very fine size because of the need of removing inorganic materials from coal. Oil agglomeration is a kind of coal cleaning technique that is used for ...
Adverse effects of topical antiglaucoma drugs on the ocular surface
(BLACKWELL SCIENCE ASIA, 2000)
Purpose: This study was designed to determine the effect of long-term antiglaucoma topical medication on the ocular surface; measuring basal Schirmer's and tear break-up time tests using conjunctival impression cytology. ...
Effect of the intense laser field on the valance band for Ga1-xAlxAs/GaAs heterostructure
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
The energy levels of holes in symmetric single quantum well under the laser field are theoretically calculated within the framework of the effective mass approximation. Results obtained show that the potential profile and ...
Peripancreatic tuberculous lymphadenitis mimicking carcinoma: Report of a case
(ACTA MEDICAL BELGICA, 2004)
Peripancreatic tuberculous lymphadenitis is a rare clinical entity and it usually raises serious diagnostic problems. We report a case of a solitary abdominal tuberculoma. A 45-year old woman was admitted to hospital with ...
Various types of glomus anastomoses in developing rat fetuses
(BLACKWELL WISSENSCHAFTS-VERLAG GMBH, 2000)
Some observations on arteriovenous anastomosis (AVA) morphogenesis of rats were considered in this investigation. Interesting typical glomus anastomoses observed under light microscopy were determined by photography before ...
Evaluation of in vitro effect of Morus rubra (red mulberry) on survival of periodontal ligament cells
(MOSBY-ELSEVIER, 2008)
Objective. The purpose of this study was to determine the ability of the juice of Morus rubra fruit to serve as a temporary storage medium for the maintenance of periodontal ligament (PDL) cell viability of avulsed teeth. ...
