Thesis Abstract

ABSTRACT         In this dissertation, lattice thermal conductivity (LTC) is computed numerically using a Modified-Debye-Callaway model, in the temperature range 2-300 K, under a hydrostatic pressure in the range 0-10GPa, for bulk silicon, naofilms (NFs) in the thickness range 20-3000 nm and nanowires (NWs) in the diameter range of 22-115 nm.        The bulk silicon […]

SUMMARY The present study includes two experiments, in the first experiment quail birds feed dried garlic powder (were the birds fed six different diets of additives , T1: control, T2: 3% lipids, T3: 2% garlic, T4: 2% garlic+ 3% lipid, T5: 4% garlic and T6: 4% garlic + 3% lipid) and in the second experiment

SUMMARY Cancer is one of the major global health problems, it is the second leading cause of death worldwide after heart disease. Leukemia is one of the top ten cancer killers. It is a blood condition caused by a disorder in the cell development process. Advanced glycation end products (AGE) and oxidative stress are two

ABSTRACT   In this dissertation, we construct iteration schemes for nonlinear problems in various types. The presented schemes are iterative methods for the scalar and system of nonlinear cases as well as for calculating matrix sign function.   In the scalar case, we designed efficient iteration schemes with memory to solve nonlinear equations in the

ABSTRACT The objective of the present work is divided into two main parts. In the first part, the theoretical calculations are performed on lattice thermal conductivity (LTC) and corresponding parameters for the zinc blende and wurtzite structure of InAs nanowires (NWs) with diameters of 50, 63, 66, 100, and 148 nm through the Debye–Callaway model.

It includes also information about silver nanoparticles, methods used for synthesizing of it and most important characterization techniques. In addition to that it contains general information about two sulfa drugs (Sulfamethoxazole and Sulfacetamide sodium) which are determined by the

Nonstandard Completion of Non-complete Metric Spaces By: Ala Omer Hassan ABSTRACT Standardly, to prove that a metric space is complete, it is equivalence to proving that every Cauchy sequence in  is convergent to a point in it. There are a lot of spaces or sets  which agree with this property except at a small size

Abstract In this study, the structure and electronic characteristics of nitrogen-dopedanatase TiO 2 , TiO 2 (101) surface, nanocrystal, and nanocluster were investigatedusing first-principles computations. Also, the influence of impurity location onTiO 2 electronic properties was studied, which affects photocatalytic properties.Firstly, the electronics properties of the nitrogen-doped anatase TiO 2 of the purehost lattice are
