Optical intersubband transitions in double Si delta-doped GaAs under an applied magnetic field
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
For different applied magnetic fields, the intersubband transitions of double Si delta-doped GaAs structures is theoretically investigated for a uniform donor distribution. The electronic structure has been calculated by ...
Ground state energy of excitons in quantum dot treated variationally via Hylleraas-like wavefunction
(IOP PUBLISHING LTD, 2009)
In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under ...
Ocular Findings in Patients with Crimean-Congo Hemorrhagic Fever
(ELSEVIER SCIENCE INC, 2009)
PURPOSE: To describe ocular findings of patients with Crimean-Congo hemorrhagic fever (CCHF). DESIGN: Prospective, interventional, consecutive case series. METHODS: This study was conducted in Sivas, a city located in the ...
DEPENDENCE OF CHARACTERISTIC DIODE PARAMETERS IN Ni/n-GaAs CONTACTS ON THERMAL ANNEALING AND SAMPLE TEMPERATURE
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
We have prepared the sputtered Ni/n-GaAs Schottky diodes which consist of as deposited, and diodes annealed at 200 and 400 degrees C for 2 min. The effect of thermal annealing on the temperature-dependent current-voltage ...
Ultimate loads for eccentrically loaded model shallow strip footings on geotextile-reinforced sand
(ELSEVIER SCI LTD, 2009)
A series of tests were carried out with an eccentrically loaded model surface shallow strip footing on reinforced dense sand to investigate the decrease of the ultimate loads with increasing eccentricity and to compare the ...
Effects of different postmenopausal hormone therapy regimens on cerebral blood flow and cognitive functions
(SPRINGER, 2009)
The purpose of this study was to compare the effects of different postmenopausal hormone therapy regimens, namely conjugated equine estrogens (CEE), CEE plus medroxyprogesterone acetate (MPA), tibolone, and raloxifene on ...
Determination of the Antimicrobial and Antioxidative Properties and Total Phenolics of Two "Endemic" Lamiaceae Species from Turkey: Ballota rotundifolia L. and Teucrium chamaedrys C. Koch
(SPRINGER, 2009)
This study was designed to examine the in vitro antimicrobial and antioxidant activities and the amount of total phenolics of the methanol extracts of Ballota rotundifolia L. and Teucrium chamaedrys C. Koch. In the case ...
Vascular graft infection by Staphylococcus aureus: efficacy of linezolid, teicoplanin and vancomycin systemic prophylaxis protocols in a rat model
(CLINICS CARDIVE PUBL PTY LTD, 2009)
Objective: We investigated experimentally the in vivo prophylactic efficacies of linezolid, teicoplanin and vancomycin in subcutaneously implanted dacron graft infection caused by methicillin-resistant Staphylococcus aureus ...
Spatial correlation of the aeromagnetic anomalies and seismogenic faults in the Marmara region, NW Turkey
(ELSEVIER SCIENCE BV, 2009)
Previous investigations into the deep structure of the Marmara Sea region revealed an existence of a rigid barrier located at the centre of the Marmara Sea. Thus, the North Anatolian Fault (NAF) was divided into three ...
Temperature distribution study in resistance spot welding
(NATL INST SCIENCE COMMUNICATION, 2009)
This paper presents effect of sheet thickness and current density on cooling speed and temperature distribution in resistance spot welding. Thicker sheets have higher temperatures in weld zones. Temperatures are higher in ...
