Influence of temperature on the electronic properties of Si delta-doped GaAs structures
(E D P SCIENCES, 2003)
We have investigated theoretically the electronic structure of Si delta-doped GaAs layers at T = 0 K and at room temperature. For a nonuniform distribution, we have studied their sensitivity to the donor concentration and ...
Palaeomagnetic evidence for the Gondwanian origin of the Taurides and rotation of the Isparta Angle, southern Turkey
(WILEY-BLACKWELL, 2002)
The Taurides, the southernmost of the three major tectonic domains that constitute present-day Turkey, were emplaced following consumption of the Tethyan Ocean in Late Mesozoic to mid-Tertiary times. They are generally ...
A parametric study of phenolic compounds desorption performance from organobentonite by supercritical fluids
(ELSEVIER SCIENCE BV, 2007)
Supercritical fluid desorption has been carried out in a fixed bed column to desorp nitrophenolic compounds from organically modified bentonite. The experiments were carried out in the sequence of synthesis of organobentonite ...
Thyroid hormone supplementation in sepsis: An experimental study
(SPRINGER-VERLAG, 2003)
Purpose. The levels of thyroid hormones decrease in septic, critically ill, and major trauma patients who show a bad prognosis. The aim of this study was to investigate the effects of thyroid hormone supplementation on the ...
Late Cenozoic stress states around the Bolu Basin along the North Anatolian Fault, NW Turkey
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This study defines the Late Cenozoic stress regimes acting around the Bolu Basin along the North Anatolian Fault in northwestern Turkey. The inferred regional stress regime, obtained from the inversion of measured fault-slip ...
Investigation of critical liquid fraction factor in nodular iron castings by computer simulation
(ELSEVIER SCIENCE SA, 2008)
Demands of the metal forming industry made the real time simulation method programs essential for good manufacturing of the finished product. In this paper, the CLF (critical liquid fraction) factor which is necessary for ...
Twin development in the foraminiferal genus Alveolina
(INTERPERIODICA, 2003)
The abnormal Alveolina individuals found by various researchers in different outcrops in Turkey are studied. The abnormal Alveolina individuals are classified as normal twins, Siamese twins, and teratogenetic specimens. ...
Screening of the antioxidative properties and total phenolic contents of three endemic Tanacetum subspecies from Turkish flora
(ELSEVIER SCI LTD, 2007)
Methanolic extracts of three different Tanacetum subspecies [Tanacetum densum (Lab.) Schultz Bip. subsp. sivasicum Hub-Mor and Grierson, Tanacetum densum (Lab.) Schultz Bip. subsp. eginense Heywood and Tanacetum densum ...
Determination of the breakage and wetting parameters of calcite and their correlations
(WILEY-V C H VERLAG GMBH, 2002)
This paper presents the breakage and wetting parameters of calcite mineral obtained experimentally and establishes a correlation between these characteristic parameters. The breakage parameter obtained from the different ...
Alterations in spontaneous contractions of rat proximal and distal colon after peritonitis
(W B SAUNDERS CO-ELSEVIER INC, 2007)
Background/ Purpose: The aim of this study was to investigate the effect of peritonitis on spontaneous contractions of distal and proximal colon smooth muscle isolated from rats. Methods: Peritonitis was induced by cecal ...
