Shallow donors in the triple-graded quantum well under the hydrostatic pressure and external fields
(ELSEVIER SCIENCE BV, 2006)
The binding energy of the donor in the triple-graded GaAs-(Ga,Al)As quantum well under the hydrostatic pressure, electric and magnetic fields are calculated by using a variational approach. The results have been obtained ...
Modification and characterization of maleic anhydride-styrene-methyl metacrylate terpolymer using various alcohols
(VSP BV, 2006)
In this Study, the anhydride units in maleic anhydride-styrene-methyl metacrylate terpolymer (MA-St-MMA) were reacted with n-propyl, n-butyl, n-pentyl and n-benzyl alcohols, and the ester derivatives of MA-St-MMA terpolymer ...
Wear behavior of different surface treated cam spindles
(ELSEVIER SCIENCE SA, 2006)
In this study wear behavior of cam spindles made of five different surface treated nodular cast iron (GGG50) and induction hardened CK45 steels was investigated. In the experiments; PVD-TiN-coated, both borided and ...

(SAUDI MED J, 2006)
Objectives: The aim of this cross-sectional study was to identify the infant feeding practices and to evaluate the attitudes and beliefs of mothers on breast-feeding in Turkey. Methods: This study was established in 10 ...
Swelling characterization of gamma-radiation induced crosslinked acrylamide/maleic acid hydrogels in urea solutions
(ELSEVIER SCI LTD, 2006)
Swelling behaviors of crosslinked acrylamide/maleic acid (CAMA) hydrogels synthesized by gamma-radiation crosslinking of acrylamide and maleic acid in aqueous urea solutions were investigated. CAMA hydrogels containing ...
Screening of the antioxidative and antimicrobial properties of the essential oils of Pimpinella anisetum and Pimpinella flabellifolia from Turkey
(ELSEVIER SCI LTD, 2006)
The aerial parts of two endemic Pimpinella [Pimpinella anisetum Boiss. & Ball. and Pimpinella flabellifolia (Boiss.) Benth. ex Drude] were hydro-distilled to produce oils in the yields of 2.07% (v/w) and 2.61% (v/w), ...
Broadband staircase quantum well infrared photodetector with low dark current
(ELSEVIER SCIENCE BV, 2006)
We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). It detects wavelengths between 8.8 mu m and 12.3 mu m at an applied electric field of F= 6 x 10(4) V/cm at room ...
Values in Turkish middle school mathematics textbooks
(SPRINGER, 2006)
Mathematics is usually seen as a field in which there is no values. Such a situation causes only a few studies about values teaching to be done in mathematics education. But, mathematics is a field that has various values ...
Evaluation of tumor markers CA-125 and CEA in acute myocardial infarction
(HEALTH COMMUNICATIONS INC, 2006)
Serum carbohydrate antigen (CA-125) and carcinoembryonic antigen (CEA) have always been of clinical importance in the diagnosis and follow-up of various tumors. This study was devised to investigate the relationship between ...
Mineralogy and geochemistry of Paleocene ultramafic- and sedimentary-hosted talc deposits in the southern part of the Sivas Basin, Turkey
(CLAY MINERALS SOC, 2006)
Talc deposits, located mainly in three areas of north-central Turkey, are present in the ophiolitic series of the Cretaceous and in siliciclastic rocks of the Paleocene. Talc deposits related to ophiolites are between ...
