The effect of an intense laser field on magneto donors in semiconductors
(ELSEVIER SCIENCE BV, 2003)
The laser-field dependence of the binding energy of shallow-donor impurities in graded, and square quantum wells under the external magnetic field is calculated by a variational method and in the effective mass approximation. ...
Explosive-based anchoring system in cable bolts
(MANEY PUBLISHING, 2003)
This study deals with research work based on a new explosive-based anchorage system for cable bolts. The aim of this system is to apply pre-tension to cable bolts, which is independent of cement mortar. Within the scope ...
Cu(II) removal from aqueous solution using Dogantepe (Amasya) zeolites
(INDERSCIENCE ENTERPRISES LTD, 2003)
This paper investigates the effects of zeolite particle size, zeolite/solution ratio and stirring time on the performance of zeolites from Dogantepe in removing Cu(II) from aqueous solution to establish optimum operating ...
The measurement of the rotational deformities with computed tomography in femoral shaft fractures of the children treated with early spica cast
(ELSEVIER SCI IRELAND LTD, 2003)
Twenty-eight children with femoral shaft fractures, treated with early spica cast, were evaluated with computed tomography (CT), for their femoral shaft rotational deformities. The femoral torsion angles were measured on ...
On the spectrum and fine spectrum of the compact Rhaly operators
(INDIAN NAT SCI ACAD, 2003)
In 1989, Rhaly determined the spectrum of Rhaly operator R-a regarded as an operator on the Hilbert space I-2 normed by parallel to x parallel to = (Sigma(n) \ x(n) \(2))(1/2). It is the purpose of this paper to determine ...
Antimicrobial and antioxidant activity of the essential oil and methanol extracts of Thymus pectinatus Fisch et Mey. var. pectinatus (Lamiaceae)
(AMER CHEMICAL SOC, 2003)
The essential oil, obtained by using a Clevenger distillation apparatus, and water-soluble (polar) and water-insoluble (nonpolar) subfractions of the methanol extract of Thymus pectinatus Fisch. et Mey. var. pectinatus ...
Heavy metal accumulation in street dust samples in Sivas
(MARCEL DEKKER INC, 2003)
Heavy metal contents of street dust samples collected from seven sites located in and around urban areas in Sivas city, Turkey, were determined by atomic absorption spectrometry after digestion using a mixture of acids. ...
Fundamental aspects of spherical oil agglomeration of calcite
(ELSEVIER SCIENCE BV, 2003)
In this study, concentration of calcite particles was investigated using oil agglomeration. For this purpose, effects of operating parameters were investigated and also zeta potential measurements and Fourier transform ...
A case with Pyle type Metaphyseal Dysplasia: Clinical, radiological and histological evaluation
(MEDECINE ET HYGIENE, 2003)
A case with Pyle type Metaphyseal Dysplasia: clinical, radiological and histological evaluation: Pyle type metaphyseal dysplasia is a rare autosomal recessive disease that is primarily affect metaphyses. Here we present a ...
Investigation of OUR and NUR experiments for nitrogen and phosphorus removal with activated sludge: a lab-scale study
(INDERSCIENCE ENTERPRISES LTD, 2003)
Activated sludge systems are widely used in wastewater treatment. Organic carbon removal and nutrient removal are important for stringent water discharge standards. Therefore, activated sludge systems are widely used to ...
