Improvement in intersubband optical absorption and the effects of device parameter variations in quantum wells with an applied electric field
(ACADEMIC PRESS LTD, 1999)
The intersubband optical absorption in symmetric and asymmetric, single and coupled, double GaAs/Ga1-xAlxAs quantum wells is calculated. The results have been obtained in the presence of a uniform electric field as a ...
Effects of intravenous anesthetic agents on pregnant myometrium
(POLISH ACAD SCIENCES INST PHARMACOLOGY, 1999)
Emergent or elective surgical procedures under general anesthesia may be required during pregnancy for some patients. For this reason, effects of anesthetics on uterine contractions are important. General anesthesia is not ...
Cristobalite formation from thermal treatment of Texas lignite fly ash
(ELSEVIER SCI LTD, 1999)
Texas lignite fly ash has been thermally treated at 1000-1200 degrees C in air, and the products analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). ...
The effect of aspirin, ticlopidine and their low-dose combination on platelet aggregability in acute ischemic stroke: a short duration follow-up study
(LIPPINCOTT WILLIAMS & WILKINS, 1999)
We investigated the effects of aspirin (300 mg/d), ticlopidine (500 mg/d) and their low-dose combination (aspirin 100 mg/d plus ticlopidine 250 mg/d) on the platelet aggregability using the Wu and Hoak method. Each treatment ...
Geology, base-precious metal concentration and genesis of the silica-carbonate alteration (listwaenites) from late Cretaceous ophiolitic melanges at central east Turkey
(GUSTAV FISCHER VERLAG, 1999)
The late Cretaceous (pre Maastrichtian) alteration of serpentinite bodies in the Divrigi and Kuluncak ophiolitic melanges has formed two distinct types of listwaenite. The earliest is silica-carbonate listwaenite (type I), ...
Effect of conjunctival structure and inflammatory cell counts on intraocular pressure after trabeculectomy
(KARGER, 1999)
Purpose: To evaluate the conjunctival structure and inflammatory cell counts and to determine the predictive value of these histological parameters for postoperative intraocular pressure (IOP) levels after trabeculectomy. ...
A new approach to solving the CO-factored force field of M(CO)(4) molecules having C-3 upsilon symmetry
(ELSEVIER SCIENCE SA, 1999)
The CO-factored force field of M(CO)(4) molecules with C-3 nu symmetry was solved using the maximum value of the sum of the interaction constants as an additional constraint. The solution obtained led to the relations which ...
The role of neutrophils in the formation of peritoneal adhesions
(OXFORD UNIV PRESS, 1999)
The most common cause of intraperitoneal adhesions which may result in infertility and intestinal obstruction is previous abdominal surgery. Surgical trauma of the peritoneum in the absence of infection elicits a rapid and ...
Effects of rhG-CSF on neutrophil functions and bone marrow parameters in diabetic rats
(MARCEL DEKKER INC, 1999)
Neutrophils have an important role in the host defense. The elevated serum glucose levels of diabetics affect traditional host defenses such as neutrophil counts and functions. The causes of these impairments are not clear. ...
Double quantum well electronic energy spectrum within a tilted magnetic field
(ACADEMIC PRESS LTD, 1999)
The analytical solutions of the Schrodinger equation for a double quantum well structure (DQWS) subjected to an externally applied tilted magnetic field are obtained and the results are discussed. The dependency of the ...
