The electric field effects on intersubband optical absorption of Si delta-doped GaAs layer
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
The intersubband transitions in Si delta-doped GaAs structures is theoretically investigated for different applied electric fields. For an uniform distribution the electronic structure has been calculated by solving the ...
Seroprevalence of Brucella in an elderly population in mid-Anatolia, Turkey
(BMC, 2003)
Brucellosis is a widespread infectious disease in the mid-Anatolia regions of Turkey. This study investigated the prevalence of Brucella infection in elderly people of this region. In total, 750 elderly subjects were chosen ...
Granuloma annulare associated with prostate carcinoma
(WILEY, 2003)
Granuloma annulare occurs as an idiopathic and benign condition, although it may be associated with some neoplasms. We describe a 60-year-old man with granuloma annulare on dorsal hands who developed prostate carcinoma. ...
Prediction of the wettability characteristics of some minerals from their breakage parameters
(ELSEVIER SCIENCE BV, 2003)
In this contribution, the breakage and wettability properties of calcite and barite minerals were presented and some correlations were established between these experimentally determined parameters. The gamma(c) relates ...
A study on friction and wear behaviour of carburized, carbonitrided and borided AISI 1020 and 5115 steels
(ELSEVIER SCIENCE SA, 2003)
The friction and wear characteristics of AISI 1020 and 5115 steel surfaces improved by various thermochemical heat treatments such as carburizing, carbonitriding and boronizing were determined. Samples prepared from the ...
Adsorption of UO22+, Tl+, Pb2+, Ra2+ and Ac3+ onto polyacrylamide-bentonite composite
(SPRINGER, 2003)
Composite of polyacrylamide-bentonite (PAA-B) was prepared by direct polymerization in a suspension of bentonite (B), the composite was then modified by phytic acid (PAA-B-Phy). The parameters related to adsorption of UO22+ ...
Crystal structure of cis,cis,cis-1,2-epoxy-3,5-dibromo-4-hydroxy tetralin
(WILEY-V C H VERLAG GMBH, 2003)
The title compound, C10OH8Br2O2, consists of a tetrahydronaphthalene skeleton composed of a six-membered ring A with arene oxide, monobromo and monohydroxy atoms in cis,cis,cis configuration held in a boat conformation and ...
Erb-B2 homodimerization inhibits MUC1 transcription in cultured human mammary epithelial cells
(WILEY, 2003)
MUC1 mucin is a heavily O-glycosylated transmembrane protein that is aberrantly expressed in many carcinomas, including breast cancer. In the present study, the effect of signaling generated from the Erb-B2 homodimer as a ...
Pneumatosis cystoides intestinalis associated with duodenal ulcer and pyloric stenosis: Report of two cases
(KARGER, 2003)
Pneumatosis cystoides intestinalis (PCI) is a rare benign condition affecting portions of the intestinal tract and is characterized by multiple subserosal and submucosal gas cysts of unknown etiology and nonspecific clinical ...
Flow-rate and pollution characteristics of domestic wastewater
(INDERSCIENCE ENTERPRISES LTD, 2003)
The characteristics of the flow-rate and pollution parameters of the domestic wastewater of a medium-size city (Sivas, Turkey) have been investigated. The design and the operating parameters of a wastewater treatment plant ...
