Electrolysis of MgCl2 with a top Inserted anode and an Mg-Pb cathode
(Kluwer Academic Publishers, 1994)High energy consumption in the production of magnesium by molten salt electrolysis is mainly due to the recombination of magnesium and chlorine. The large interelectrode distance used, in conventional techniques, to reduce ... -
Adsorption equilibrium and dynamics of lactase/CM-Sephadex system
(Kluwer Academic Publishers, 1995-08)Partitioning behaviour and adsorption isotherms of lactase/CM-Sephadex system at equilibrium were investigated together with the adsorption kinetics in this study. Maximum adsorption was obtained at the pH values between ... -
Modeling deficit irrigation in alfalfa production
(American Society of Civil Engineers, 1995-11)A conceptual agronomic model EPIC was extended to consider the effects of salinity in alfalfa production under optimal and water stress irrigation conditions. The extended model was calibrated and validated with observed ... -
Material parameters of quaternary III–V semiconductors for multilayer mirrors at 1:55 μm wavelength
(IOP Publishing, 1996)Nine quaternary (Al,Ga,In) - (P,As,Sb) semiconductor compounds lattice matched to InP are investigated theoretically. Direct bandgap, refractive index at wavelength, and thermal conductivity are calculated as a function ... -
Propagation of waves in porous media
(Elsevier, 1996)Wave propagation in porous media is of interest in various diversified areas of science and engineering. The theory of the phenomenon has been studied extensively in soil mechanics, seismology, acoustics, earthquake ... -
Body waves in poroelastic media saturated by two immiscible fluids
(American Geophysical Union, 1996)A study of body waves in elastic porous media saturated by two immiscible Newtonian fluids is presented. We analytically show the existence of three compressional waves and one rotational wave in an infinite porous medium. ... -
Use of clinoptilolite in ethanol dehydration
(Taylor & Francis, 1996)Clinoptilolite-type natural zeolite, which exists in various regions of Turkey, has been experimentally studied. For the ethanol-water-local clinoptilolite system, uptake and breakthrough curves were determined under a ... -
Flexible poly(vinyl chloride)-zeolite composites for dye adsorption from aqueous solutions
(Taylor & Francis, 1996)Flexible poly(vinyl chloride) (PVC) composites having natural zeolite clinoptillolite were prepared by plastisol-plastigel technology. Adsoption of methylene blue on each raw material and on composites was studied both ... -
Oil mound spreading and migration with ambient ground flow in coarse porous media
(American Geophysical Union, 1996-05)When a light, immiscible oil leaks above an unconfined aquifer, it spreads and forms a floating mound on the table. The oil mound migrates in the direction of ambient ground flow. In this study we present a governing ... -
Wave propagation in fractured porous media
(Kluwer Academic Publishers, 1996-06)A theory of wave propagation in fractured porous media is presented based on the double-porosity concept. The macroscopic constitutive relations and mass and momentum balance equations are obtained by volume averaging the ... -
Body waves in fractured porous media saturated by two immiscible Newtonian fluids
(Kluwer Academic Publishers, 1996-06)A study of body waves in fractured porous media saturated by two fluids is presented. We show the existence of four compressional and one rotational waves. The first and third compressional waves are analogous to the fast ... -
Consolidation of elastic porous media saturated by two immiscible fluids
(American Society of Civil Engineers, 1996-11)A theory is presented to simulate the consolidation of elastic porous media saturated by two immiscible Newtonian fluids. The macroscopic equations, including mass and momentum balance equations and constitutive relations, ... -
High strain-rate compression testing of a short-fiber reinforced aluminum composite
(Elsevier, 1997)Compression behavior of 15–26 Vf% Saffil™ short-fiber reinforced Al-1.17wt.%Cu alloy metal matrix composites has been determined over a strain-rate range of approximately 10−4 to 2×103 s−1. The strain-rate sensitivity of ... -
Vector modal solution of evanescent coupler
(IEEE, 1997-12)We present a vector modal solution for the evanescent coupler comprising an optical fiber and a slab waveguide. We identify the normal vector ridge modes of the device for different configurations. The dispersion characteristics ... -
Dynamic properties of metal matrix composites: a comparative study
(Elsevier, 1998)Three distinctly different metal matrix composites have been tested at strain rates from quasi-static to ≈3000 s−1. It was found that the high strain rate response of each composite was determined primarily by (a) the ... -
Quasi-static and dynamic compression behaviour of an FPTM alumina-reinforced aluminium metal matrix composite
(Kluwer Academic Publishers, 1998)An aluminium metal matrix composite reinforced with continuous unidirectional α-alumina fibres has been compression tested at quasi-static and dynamic strain rates. In the transverse direction, the composite showed increasing ... -
Dry deposition fluxes and mass size distributions of Pb, Cu, and Zn measured in Southern Lake Michigan during AEOLOS
(American Chemical Society, 1998)As part of the Atmospheric Exchange Over Lakes and Oceans Study (AEOLOS) the dry deposition fluxes and atmospheric size distributions (ASDs) of anthropogenic metals were measured over the southern basin of Lake Michigan. ... -
High strain rate behavior of a SiC particulate reinforced Al2O3 ceramic matrix composite
(Elsevier, 1998)The high strain rate deformation behavior of composite materials is important for several reasons. First, knowledge of the mechanical properties of composites at high strain rates is needed for designing with these materials ... -
