Mechanical and Thermal Properties of Chemically Modified Epoxy Resin
(Scientific Research, 2012-10)Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a ... -
Modelling of Internal Stresses in Sheet Glass during the Cooling
(Scientific Research, 2011-06)Internal stresses in glass are generated by interactions between thermal contraction, elasticity at low temperatures, viscoelastic flow at higher temperature, and temperature gradients caused by cooling. This work intends ... -
Moderate Hyperthermia Induces Apoptosis in Metaphase-Arrested Cells But Not in Interphase Hela Cells
(Scientific Research Publishing, 2016-06)Metaphase-arrest agents and hyperthermia are both known to be capable of inducing apoptosis, and they have been used, separately, in cancer treatments. Here, we have examined whether the two treatments together may have a ... -
Molecular Dynamics Simulations of Atomistic Detailed Hydration Structures of Poly(vinyl methyl ether)
(2015-11)Molecular dynamics simulations have been performed on the aqueous solutions of Poly(vinyl methyl ether) (PVME) at various concentrations. Both radial and spatial distribution functions are used to investigate the detailed ... -
Molecular Simulation of Ion Transport at the Water/Vapor Interface
(Scientific Research, 2012-08)Molecular dynamics was used to quantify the role of the size, charge and polarisability of F– , Cl– , Br– , I– and Na+ ions in their distribution in the water/vapour interface system. Our results show that the ... -
Multi-Spectral and Fluorescence Imaging in Prevention of Overdose of Herbicides: The Case of Maize
(Scientific Research, 2017-04)Evaluation of the impact of herbicides on maize was done through multispectral and multi-modal imaging and multi-spectral fluorescence imaging combined with statistical methods. Spectra containing 13 wavelengths ranging from ... -
Multiscale Modeling of Exocytosis in the Fertilization Process
(2014-09)We discuss the implementation of a multiscale biophysico-chemical model able to cope with the main mechanisms underlying cumulative exocytosis in cells. The model is based on a diffusion equation in the presence of external ... -

Nanoscale Stiffness Distribution in Bone Metastasis
(Scientific Research, 2015-12)Nanomechanical heterogeneity is expected to have an effect on elasticity, injury and bone remodelling. In normal bone, we have two types of cells (osteoclasts and osteoblasts) working together to maintain existing bone. ... -
Natural Bond Orbital Analysis of [Fe(H2O)6]2+/3+ and [Zn(H2O)6 ]H2On2+; N=0-4
(2016-09)Nature of delocalization of the electrons from the ligands to metals in the first coordination sphere of the highspin complexes [Fe(H2O)6]2+/3+ and [Zn(H2O)6]2+ are computationally studied using density functional theory. ... -
New Method for Synthesis of Coatings of Molybdenum, Tungsten, Their Carbides and Composites
(Scientific Research, 2013-04)In this paper we report, for the first time, a new approach for synthesis of high quality faceted microcrystalline coatings of molybdenum (Mo), tungsten (W), their carbides and composites. These studies are carried out ... -
Non-thermal Influence of A Weak Microwave on Nerve Fiber Activity
(2014-10)This paper presents a short selective review of the non-thermal weak microwave field impact on a nerve fiber. The published results of recent experiments are reviewed and analyzed. The theory of the authors is presented, ... -
The Novel Pyruvated Glucogalactan Sulfate Isolated from the Red Seaweed, Hypnea pannosa
(Scientific Research Publishing, 2016-06)The polysaccharide was isolated from Hypnea pannosa which was grown in Okinawa, Japan. The yield of the polysaccharide was 17.2%, and the total carbohydrates, pyruvic acid, sulfuric acid and ash contents were 55.2%, 3.8%, ... -
A Novel Technique for Determination of Flow Characteristics of Blast Furnace Slag
(Scientific Research, 2012-06)A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures. The slag with a narrow difference between the two temperatures is termed a “Short Slag”. Its ... -
On-Line Measurement of the Chemical Oxygen Demand in Wastewater in a Pulp and Paper Mill Using Near Infrared Spectroscopy
(Scientific Research, 2014-10)Although near infrared (NIR) spectroscopy has been evaluated for numerous applications, the number of actual on-line or even on-site industrial applications seems to be very limited. In the present paper, the attempts ... -
