Optical properties of excitons in quantum well wires under the magnetic field
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2003)
The binding energy of excitons in quantum well wires of GaAs surrounded by Ga1-xAlxAs was calculated in an effective mass approximation with the use of the variational approach. Results obtained show that the exciton binding ...
Fine dry grinding of zeolite in a laboratory ball mill
(WILEY-V C H VERLAG GMBH, 2003)
This paper presents the importance and usage of natural zeolites, which was recently recognized in the industry. Therefore, the grinding properties of natural zeolite were studied with the emphasis on a kinetic study in a ...
Treatment of phacomatosis pigmentovascularis: A combined multiple laser approach
(LIPPINCOTT WILLIAMS & WILKINS, 2003)
BACKGROUND. Phacomatosis pigmentovascularis (PPV) consists of a capillary malformation with a variety of melanocytic lesions, which involve various regions of the body and are difficult to treat with conventional therapeutic ...
Gastric necrosis and perforation caused by acute gastric dilatation: Report of a case
(SPRINGER-VERLAG, 2003)
We report the case of an 18-year-old, mentally retarded boy who suffered acute abdominal symptoms and signs after eating a heavy meal. Laparotomy showed massive gastric dilatation with near-total infarction and perforation. ...
Cold exposure differentially stimulates angiogenesis in glycolytic and oxidative muscles of rats and hamsters
(CAMBRIDGE UNIV PRESS, 2003)
Control (normothermic) and cold-acclimated (environmental temperature gradually reduced from 20 to 5 C for 4 weeks) groups of male rats and hamsters were compared to elucidate the nature of angiogenesis in oxidative and ...

The seven flap Z-plasty revisited
(ELSEVIER SCI LTD, 2003)
Although multiple Z-plasties are widely used for burn contractures, the seven flap Z-plasty procedure has not gained wide acceptance in plastic surgery practice. However, the technique has the advantage of achieving more ...
Relaxant effect of omeprazole and lansoprazole in guinea pig gallbladder muscle strips in vitro
(SPRINGER JAPAN KK, 2003)
Background. The aim of this study was to investigate the role of omeprazole and lansoprazole, H+-K+ ATPase inhibitors, in gallbladder smooth muscle contractility in vitro. Methods. Gallbladder muscle strips obtained from ...
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 ...
