Binding energy of hydrogenic impurities in a quantum well under the tilted magnetic field
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
This paper treats theoretically the angle dependence of the ground state binding energy of a shallow donor impurity in semiconductor quantum-well systems on the tilted magnetic field. By making an appropriate coordinate ...
Effect of nifedipine on the healing of left colonic anastomoses in rats
(SPRINGER-VERLAG, 2003)
Purpose Ca2+ channel blockers inhibit collagenase production and have a vasodilatatory effect. They also restrict the formation of ischemia-reperfusion induced free oxygen radicals. The aim of this study was to assess the ...
Immobilization of Saccharomyces cerevisiae on to acrylamide-sodium acrylate hydrogels for production of ethyl alcohol
(ELSEVIER SCIENCE INC, 2003)
Acrylamide/sodium acrylate (AAm/SA) copolymers, prepared by using various crosslinkers, were used in experiments on swelling, diffusion, immobilization of yeast cells (Saccharomyces cerevisiae) and production of ethyl ...
Strong association between the GSTM1-null genotype and lung cancer in a Turkish population
(ELSEVIER SCIENCE INC, 2003)
Glutathione S-transferases are possibly related to the detoxification of many xenobiotics involved in the etiology of cancer. To investigate the role of the glutathione S-transferase M1 deletion (GSTM1-null) in lung cancer, ...
Performance of different oils in oil agglomeration of Zonguldak coal
(NATL INST SCIENCE COMMUNICATION, 2003)
In this study, comparison of performance of different oils, in the cleaning of Zonguldak coal, by oil agglomeration was investigated. The feed coal was agglomerated with both classic oils (kerosene, diesel and fuel) used ...
Sigmoid colon perforation as an unusual complication of Behcet's syndrome: Report of a case
(SPRINGER-VERLAG, 2003)
A 47-year-old man with long-standing Behcet's syndrome presented with an acute abdomen, and was found to have perforation of the sigmoid colon. Laparotomy revealed gangrenous changes in the sigmoid colon and perforation ...
Chemical and antioxidant properties of Laurocerasus officinalis Roem. (cherry laurel) fruit grown in the Black Sea region
(AMER CHEMICAL SOC, 2003)
Laurocerasus officinalis Roem. is a summer fruit highly characteristic of the Black Sea region. The edible parts of the fruit were tested for chemical composition and antioxidant properties. Total moisture, ash, protein, ...
Relapsing polychondritis with involvement of posterior inferior cerebellar artery causing acute lateral medullary syndrome
(LIPPINCOTT WILLIAMS & WILKINS, 2003)
We present a patient with relapsing polychondritis who presented with findings of lateral medullary syndrome, known as the syndrome of Wallenberg, produced by infarction of a wedge of lateral me dulla lying posterior to ...
Influence of an applied electric field on the electronic properties of Si delta-doped GaAs
(E D P SCIENCES, 2003)
We have theoretically studied the electronic structure of Si delta-doped GaAs inserted into an infinite quantum well as dependent on the applied electric field. For the uniform distribution we have investigated the influence ...
Histopathological changes in ovary and endometrium after tubal ligation: a rat model
(BLACKWELL MUNKSGAARD, 2003)
Background. To evaluate the histopathological effects of tubal ligation on ovary and endometrium in a rat model. Methods. Twenty-four female Wistar albino rats weighing 220-260 g were used. The rats were assigned randomly ...
