The main objective of this study is to determine the concentrations of Interleukine-6, Vitamins A, E, and C in patients with FMS. This study included 60 patients with FMS were diagnosed according to the American college of Rheumatology (ACR) 1990 criteria. They were obtained from the people attending the Rheumatology…
The effect of both the process-induced defects and the dopant on the time- dependent-dielectric breakdown in Ta2O5 stacks is discussed. The breakdown degradation is analyzed in terms of specific properties of high-k stacks which make their dielectric breakdown mechanism completely different from that of classical SiO2…
We emulate the spike-timing dependent plasticity (STDP) behavior of biological synapse in two phase change memory (2-PCM) cells with 3x nm technology, which has been considered as a formulated Hebbian learning rule of our cognition, learning and memory abilities. Various STDP behaviors are successfully realized in 2-P…
This research relates to treated deinked Mixed Office Waste (MOW) paper cellulosic fibers and is directed particularity to a method for improving the wet strength of recycled paper. The effect of chemical treatment of fiber was investigated. Fibers treated by 6 and 10% Succinic Acid (SA) respectively with 3 and 5% (ha…
A magnetron sputtered AlN buffer layer process has been developed using a batch PVD system capable of substrate temperatures above 800C. Epitaxial growth has been demonstrated and the film is suitable as a template for subsequent GaN growth to be utilized for LED and high power Si devices.
Abstract: The paper proposes dynamical relations with microstructure, that generalize the known equations of gradient elasticity, used for analyzing static stress-stain condition of materials with dislocations and disclinations. It is shown that the considered relations extend the equations of motion in terms of displ…
The Mass attenuation coefficient is very important parameter used in Industry, agriculture, defense, food technology and also in forensic applications. Anti social elements are mixed elements like lacto powder, urea, sabudana powder etc. in milk samples. Their mixtures are very dangerous to human health. By using gamm…
Using the Atterberg scale, liquid limit activity of clay is found to be between 0.75 and 1.25 which is acceptable for structural material in engineering, This has not been effective like lead in shielding ionizing radiation due to its brittleness. Clay samples used mainly for building construction and pot making in Ar…
work, we characterize a composite propellant using a newly-synthesized nitrate ester oxidizer (SMX) and compare it to formulations based on ammonium perchlorate (AP). The theoretical performance, handling characteristics, and physical properties are comparable, but the propellant can propagate detonations. Differentia…
I hereby declare that this submission is my own work and that, to the best of my knowledge and belief, it contains no material previously published or written by another person nor material which to a substantial extent has been accepted for the award of any other degree or diploma of the university or other institute…
An overview on the mechanical and physical properties of cross laminated timber (solid wood panels) in the building industry and its use in timber construction is presented. Structure-property relations for solid wood based materials are discussed. Important properties, such as strength, sorption, diffusion, thermal c…
For the discussed biomedical applications, the vast number of known magnetic materials is strongly reduced by the demands of biocompatibility including: (i) non-toxicity; (ii) a sufficient chemical stability in bio-environment; (iii) an appropriate circulation time in the blood; and (iv) a harmless biodegradability. A…
group box 1 （HMGB1）, which mobilizes a sub-population of non-hematopoietic cells from bone marrow into the circulation to repair skin and restore Col 7 expression. These bone marrow-derived epithelial stem/progenitor cells are derived from a lineage-negative, platelet-derived growth factor alpha-positive mesenchymal s…
SUMMARY. Deacetylation degree (DD) is one of the most important characteristics of chitosan and has great impact on its physicochemical and biological properties. In this study, three kinds of chitosan with different DD were prepared. By means of living imaging technique and fluorescent quantitative technique, the inf…
This is an experimental work carried out using speckle interferometry to measure birefringence of liquid crystal material at different wavelengths in the visible region and refractive indices were also measured. Refractive index of the liquid crystals depends on temperature at certain wavelength in the isotropic and L…
The morphology of porous silicon (p-Si) depends on several parameters such as the doping type and the carriers’ concentration of the crystalline silicon substrate. The electrolytes used in the p-Si fabrication also have an important role. The final structure determines if p-Si is luminescent or suitable for photonic a…
The present paper reports synthesis and photoluminescence characteristics of Eu 3+ (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mol %) doped red-emitting nano phosphors of Sr2Y2CeO7. The phosphor were prepared using standard solid state diffusion reaction technique without and with citric acid as flux. The formation of single pha…
Hot corrosion is the degradation of materials caused by the presence of a deposit or ash, predominantly sodium sulfate.Hot corrosion is observed in marine and aircraft engines. It is very well established that sodium sulfate alone causes accelerated oxidation of super alloys and coatings at high temperatures, where Na…
The optical and spectroscopic study of Gd 3+ and Tb 3+ ions in KZnSO 4Cl matrix have been studied in this paper. The compound KZnSO 4Cl: Ce, X (X= Gd or Tb) is prepared by wet chemical method. Photoluminescence (PL) of KZnSO 4Cl: Ce 3+ co-doped with Gd or Tb shows strong emission, and this phosphor is also efficient f…
