Adsorption of methyl violet in aqueous solutions by poly(acrylamide-co-acrylic acid) hydrogels
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)
In this study, Acrylamide(AAm)/Acrylic Acid(AAc) monomer mixtures which contain different quantities of acrylic acid have been irradiated to form hydrogels with gamma-radiation. Acrylamide/Acrylic Acid (AAm/AAc) monomer ...
The distribution of platinum-group elements (PGE) and stable isotope (O, H, S) geochemistry of Gunes-Sogucak Ni-Cu-sulfide mineralization, in Divrigi-Sivas, East-Central Turkey
(MILLPRESS SCIENCE PUBLISHERS, 2003)
The Gunes-Sogucak Ni-Cu-Sulfide mineralization from Divrigi district in Sivas province, central-east Turkey is genetically related to Upper Cretaceous ultramafic rocks, and observed as disseminated and vein type. Disseminated ...
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 ...
Unusual combination of limb malformations in the same patient: brachydactyly with syndactyly and postaxial polydactyly of the hands and postaxial oligodactyly of the feet
(LIPPINCOTT WILLIAMS & WILKINS, 2003)
We report on a case with polydactyly, syndactyly and brachydactyly of the hands and oligodactyly of the feet, but no other anomalies and normal chromosome analysis. We compared the findings in our case with those of ...
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 ...
