Barrier height effect on binding energies of shallow hydrogenic impurities in coaxial GaAs/AlxGa1-xAs quantum well wires under a uniform magnetic field
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007)
The ground state binding energies of axial hydrogenic impurities in a coaxial cylindrical quantum well wire are reported as a function of the barrier height and the radius of wire in the presence of a uniform magnetic field ...
Dithiophosphinate-pyrite interaction: Voltammetry and DRIFT spectroscopy investigations at oxidizing potentials
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The electrochemistry of dithiophosphinate (DTPI) adsorption on pyrite was investigated by cyclic voltammetry (CV) and diffuse reflectance infrared Fourier transformation (DRIFT) spectroscopy at oxidizing potentials under ...
Characterization and synthesis of some alternating terpolymers of maleic anhydride
(MATRICE TECHNOLOGY LIMITED, 2004)
In this study, MA-S-MMA, MA-S-VA and MA-S-AP terpolymers have been synthesized in methyl ethyl ketone from methyl methacrylate (MMA), vinyl acetate (VA), allyl propionate (AP), styrene (S), and maleic anhydride (MA) monomers ...
Optimization of Pb flotation using statistical technique and quadratic programming
(ELSEVIER SCIENCE BV, 2008)
A three-level Box-Behnken factorial design combining with a response surface methodology (RSM) was employed for modeling and optimizing three operations parameters of the flotation on lead flotation. The flotation studies ...
Tuberculous pericarditis: A report of three cases

Effect of climate on the bacteriology of chronic suppurative otitis media
(ANNALS PUBL CO, 2005)
Objectives: We evaluated the correlation between the microbial content of chronic suppurative otitis media (CSOM) and regional climatic parameters. Methods: We assessed the interrelations between monthly mean records of ...
Poly(acrylamide-sepiolite) composite hydrogels: Preparation, swelling and dye adsorption properties
(SPRINGER, 2006)
Polymer-clay hydrogel composite was prepared on the basis of polyacrylamide (PAAm) gel containing the clay mineral sepiolite. The properties of swelling and dye adsorption of poly(acrylamide-sepiolite) (AAm/Sep) composite ...
