Subband structure and band bending in symmetric modulation-doped double quantum wells
(EDP SCIENCES S A, 2005)
We have calculated the subband structure and confinement potential of modulation-doped Ga1-xAlxAs-GaAs symmetric double quantum wells a function of the doping concentration. Electronic properties of this structure are ...
Empyema in adults and children : Difference in surgical approaches, report of 139 cases
(ACTA MEDICAL BELGICA, 2007)
Aim : We investigated specific aetiology and different therapeutic approaches in patients with empyema in a General Thoracic Surgery Clinic. Material and methods : Charts of 139 patients admitted with empyema, between ...
Relationships between liquid limit, cation exchange capacity, and swelling potentials of clayey soils
(INTERPERIODICA, 2004)
As is known, the liquid limit has been used worldwide as an index test for a quick consistency characterization of clayey soils, as it is easy and inexpensive to determine. Consistency is a result of the hydrophilic and ...
Nurses and physicians' opinions and approaches towards the use of physical restraints
(UNIVERSITATSVERLAG ULM GMBH, 2005)
The opinions and approaches on the use of physical restraints by nurses (86) and physicians (78) working in a training hospital were investigated. The data were collected using a questionnaire developed by the researchers. ...
Validation of large-eddy simulation of strongly curved stationary and rotating U-duct flows
(ELSEVIER SCIENCE INC, 2007)
Numerical predictions of the developing turbulent flow through stationary and rotating U-ducts with strong curvature are presented using large-eddy simulation (LES). The primary aim is to validate LES in a strongly curved ...
The effect of the donor distribution on the electronic structure of two coupled Si delta-doped layers in GaAs
(ELSEVIER SCIENCE BV, 2003)
We have theoretically investigated the electronic structure of two coupled Si delta-doped GaAs at T = 0 K. For the uniform donor distribution we have studied the influence of donor concentration on the subband structure. ...
Ar-40/Ar-39 age and geochemistry of the post-collisional Miocene Yamadag volcanics in the Arapkir area (Malatya Province), eastern Anatolia, Turkey
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The Neogene Yamadag volcanics occupy a vast area between Sivas and Malatya in eastern Anatolia, Turkey. These volcanic rocks are characterized by pyroclastics comprising agglomerates, tuffs and some small outcrops of ...
Shortwall stoping versus sub-level longwall caving-retreat in Eli coal fieds
(SOUTH AFRICAN INST MINING METALLURGY, 2006)
This study deals with the presentation of the mechanized longwall mining project introduced some years ago to increase productivity and output of Aegean Lignite Establishment (ELI) owned by Turkish Coal Enterprises (TKI) ...
Liver and muscle fatty acid composition of mature and immature rainbow trout (Oncorhynchus mykiss) fed two different diets
(VERSITA, 2007)
Fatty acid composition of liver and muscle tissues of immature and mature Oncorhynchus mykiss fed on two different diets were determined. Fatty acid analyses were carried out by gas chromatography. Palmitic acid (C16:0), ...
Clinical and histologic evaluations of experimental Acanthamoeba keratitis
(SPRINGER, 2007)
Amoebic keratitis, a sight-threatening, progressive corneal disease, is commonly caused by ubiquitous, pathogenic, free-living Acanthamoeba spp., which are widely distributed in the environment. We investigated clinical ...
