Synergistic effect of the locust bean gum on the thermal phase transitions of kappa-carrageenan gels
(Elsevier Sci Ltd, 2009-03)
Synergism between K-carrageenan and locust bean gum (LBG) was studied using the photon transmission technique. Synergistic effects in these polymeric mixtures strongly affected the physical properties of the gel structure. ...
A new method for the source localization in sectionally homogeneous bounded domains involving finitely many inner interfaces of arbitrary shapes
(Pergamon-Elsevier Science, 2001-05)
A new method to localize a static point source buried in a nonhomogeneous bounded domain composed of finitely many homogeneous parts separated by interfaces of arbitrary shapes was established. The source can be a simple ...
Synthesis and liquid crystalline behavior of random copolymer of poly(ethylene oxide) macromonomer and liquid crystalline monomer by the photon transmission technique
(Taylor & Francis Inc, 2005-12)
Random copolymers of poly(ethylene oxide) macromonomer with p-vinylbenzyl end-functional group (PEOVB) and liquid crystalline monomer, namely 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (COA), were prepared by conventional ...
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)
Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ...
Strategies for the evolution of sex
(American Physical Soc, One Physics Ellipse, 2001-12)
We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ...
Calculation of the T-X phase diagram for a mixture of liquid crystals
(Pergamon-Elsevier Science, 2000-12)
In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. ...
Electron-phonon mass enhancement parameter of the (Gamma) over-bar surface state on Au(111) measured by photoemission spectroscopy
(American Physical Society, 2006-07)
We report the measurement of lambda, the electron-phonon mass enhancement parameter, for the spin-orbit-split Gamma surface state on Au(111). lambda is determined from the change of the photoemission linewidth as a function ...
Study of drying of kappa-carrageenan gel at various temperatures using a fluorescence technique
(Taylor & Francis Inc, 2008-01)
The steady-state fluorescence technique was used to study drying of kappa-carrageenan gel at various temperatures. Pyranine was doped as a fluorescence probe, and scattered light, I-sc, and fluorescence intensities, I, ...
Measurement and assessment of fatigue life of spot-weld joints
(Asme-Amer Soc Mechanical Eng, 2009-01)
Spot-weld joints are commonly used to fasten together metal sheets. Because fatigue fracture is the most critical failure mode for these joints under fluctuating loads, understanding their fatigue failure behavior and ...
Small molecule diffusion into swelling Iota-Carrageenan gels: A fluorescence study
(Taylor & Francis Group, 2007-04)
Small molecule diffusion into Iota-Carrageenan gel was studied by using steady-state fluorescence (SSF) technique. Pyranine, dissolved in water was used as fluorescence probe. Fluorescence emission intensity, I-p, and ...
