Synthesis and characterization of boron carbide films by plasma-enhanced chemical vapor deposition
(TAYLOR & FRANCIS INC, 2003)
The plasma-enhanced chemical vapor deposition of boron carbide was investigated on quartz glass and alumina substrates from a gas mixture of BCl3, H-2, and CH4 in an inductively coupled plasma (ICP) medium produced by a ...
Higher glutathione transferase GSTM1 0/0 genotype frequency in young thyroid carcinoma patients
(TAYLOR & FRANCIS LTD, 2003)
Objective: Glutathione S-transferases (GSTs) comprise a large supergene family and detoxify a variety of endogenous and exogenous electrophilic compounds. Since many GSTs are polymorphic, there has been considerable interest ...

Use of Q-switched ruby laser in the treatment of nevus of Ota indifferent age groups
(WILEY-LISS, 2003)
Background and Objectives: Nevus of Ota is a form of dermal melanocytic hamartoma that appears as a bluish discoloration in the trigeminal region. Although Q-switched lasers provide effective treatment, the appropriate age ...
Exciton absorption in quantum-well wires under the electric field
(ELSEVIER SCIENCE BV, 2003)
The binding energy of excitons, and interband optical absorption in quantum-well wires of GaAs surrounded by Ga1-xAlxAs is calculated in effective-mass approximation, using a variational approach. Results obtained show ...
Fluid-inclusion and stable-isotope characteristics of the Inler Yaylasi lead-zinc deposits, northern Turkey
(TAYLOR & FRANCIS INC, 2003)
The Eastern Black Sea Region of Turkey contains over 400 massive (Kuroko-type) and vein-type Cu-Pb-Zn deposits. The Inler Yaylasi lead-zinc deposits are typical examples of the vein type and have been economically mined ...
Binding energies of shallow donor impurities in different shaped quantum wells under an applied electric field
(ELSEVIER SCIENCE BV, 2003)
We present a variational method to compute the binding energies for a hydrogenic impurity located at the center of the finite parabolic (PQW), V-shaped (VQW or full graded well) and square (SQW) GaAs-Ga1-xAlxAs quantum ...
Electronic properties of two coupled Si delta-doped GaAs structures
(E D P SCIENCES, 2003)
We have theoretically investigated the subband structure of two coupled Si delta-doped GaAs at T = 0 K. For the uniform distribution we have studied the influence of the separation between the two doping layers. The ...
Treatability studies on wastewater from textile dyeing factories in Bursa, Turkey
(INDERSCIENCE ENTERPRISES LTD, 2003)
The textile industry is one of the most rapidly developing industries in Turkey. It generates a large amount of wastewater, with corresponding concerns about pollution. The main sources of pollution in wastewater are the ...
Investigations for modification of polyacrylamide-bentonite by phytic acid and its usability in Fe3+, Zn2+ and UO22+ adsorption
(SPRINGER, 2003)
Composite of polyacrylamide-bentonite (PAA-B) was prepared by direct polymerisation of PAA in a suspension of bentonite (B). Adsorption and thermodynamic features of phytic acid (Phy) adsorption onto B, PAA and PAA-B, and ...
