Magnetic and Photon Cascade Emission of Gd3+ of NaGd(PO3)4 Monocrystal Under Appropriate Synthesis Conditions
(2017-08)A signal crystal of NaGd(PO3)4 (NGP) was successfully grown with the solid-state reaction method under appropriate synthesis conditions. Structure refinements and the purity of the samples were determined by XRD patterns. ... -
Marine Invertebrates as Bioindicators of Heavy Metal Pollution
(Scientific Research, 2014-12)Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are ... -
A Mass Spectrometric Study of Kratom Compounds by Direct Infusion Electrospray Ionization Triple Quadrupole Mass Spectrometry
(Scientific Research Publishing, 2016-06)Mitragynine (MG) and its major metabolites 7-hydroxymitragynine (7-OH-MG) are two of the major components of the plant extract Kratom, which is a tree planted in Southeast Asia. Kratom has long been used by opioid-dependent ... -
Measurement of the Potassium Content of Different Food Samples with High Purity Germanium Detectors
(Scientific Research Publishing, 2016-07)Measurements of the potassium content of samples of food, performed with High Purity Germanium detectors, are presented in this paper. The potassium content was measured by identifying the 1460 keV photons produced in the ... -
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 ... -
