The Effect of Au Nanoparticles on the Structural and Optical Properties of (NiO:WO3) Thin Films Prepared by PLD Technique
...Show More Authors

      In the present investigation, (NiO:WO3 ) thin films were deposited at RT onto glass substrates  using PLD technique employing focused Nd:YAG laser beam at 600 mJ with a frequency second radiation at 1064 nm (pulse width 9 ns) repetition frequency (6 Hz), for 400 laser pulses incident on the target surface .The structural, morphological and optical properties of the films doped with  different concentration of  Au content (0.03, 0.05, and 0.07) were examined with X-ray diffractometer(XRD), Atomic Force Microscope(AFM) , UV–Vis spectrophotometer . The results show that the films were amorphous with small peaks appearing when doped with AuNPs . The XRD peaks of the deposited NiO:WO3 were enhanced with increasing the Au content  .  The crystalline size of the deposited thin films was calculated using Debye Scherer formula and found to decrease from 6.6 nm for undoped NiO:WO3 to  3.4 nm for doped (NiO:WO3) with the increase of Au content from x=0 to x=0.07  at preferred orientation of (200). All the samples have a cubic structure. Also, the results showed that Au content of the films affects the surface morphology. From the results of AFM analysis, it was found that the roughness and average diameter change when adding Au to the structure, with the highest value occurring at Au ratio 0.03 equal to 7.58 and 81.02 nm, respectively. UV–Vis spectrophotometer was used to investigate the optical transmission. It was found that when Au content of films increased, the transmittance of films decreased.

The Role of motive in the criminalization of terrorism
...Show More Authors

The roll of motive in the legal model of terrorist crimes. It's important to define the roll of motives in modern criminal policy as whole and terrorist crimes in specific Motives are important mental elements regarding the criminals, criminalization, deterrent, and criminal charges.

Modern terrorist crimes are national and international immediate and dangerous threat to individuals lives, properties, and their Holly believes. Terrorists acts aimed to spreading fears, and desperation in hearts of persons and social institutions in order to enforce ideological system. This is explaining legislative attention toward Terrorists motives in the construction of criminal intent. Motives is the core of any Effective criminal justice syst

Provisions of the uncertain fate of the Penal Code

Under the provisions of the old penal laws were criminal responsibility collectively If someone commits murder of the tribe was the victim belongs to another tribe was wasting his blood as a murderer and have each person of the tribe personally responsible for this crime. If it does not contribute to it or did not know, however, committed to achieving voices calling goodness and justice demand soared to impose punishment on the person who is connected to the crim.

The French Revolution and its leaders credited with establishing the principle of personal punishment and responsibility in contemporary penal laws did this concept is limited to the advancement of the criminal liability of play a role in the commission of the crime, bu

Theoretical and Experimental Study for Corrosion Inhibition of Carbon Steel in Salty and Acidic Media by A New Derivative of Imidazolidine 4-One
...Show More Authors

A new imidazolidine 4-one derivative, of namly 2-[2-(4-Bromo-phenyl)-imidazo [1,2-a] pyridine-3-yl]-3-(4-nitro-phenyl)-imidazolidine-4-one (BPIPNP) was investigated as corrosion inhibitor for carbon steel in salty (3.5% NaCl) and acidic (0.5M HCl) solutions using potentiometric polarization measurements. The results revealed that the percentage inhibition efficiencies (%IE) in the salty solution (90.67%) are greater than that in the acidic solution (83.52%). Experimentally, the thermodynamic parameters obtained have supported a physical adsorption mechanism and which followed Langmuir adsorption isotherm. Density Functional Theory (DFT) of quantum mechanical method with B3LYP 6-311++G (2d, 2p) level was used to calculate geometrical stru

Spatial Data Analysis for Geostatistical Modeling of Petrophysical Properties for Mishrif Formaiton, Nasiriya Oil Field
...Show More Authors

Spatial data analysis is performed in order to remove the skewness, a measure of the asymmetry of the probablitiy distribution. It also improve the normality, a key concept of statistics from the concept of normal distribution “bell shape”, of the properties like improving the normality porosity, permeability and saturation which can be are visualized by using histograms. Three steps of spatial analysis are involved here; exploratory data analysis, variogram analysis and finally distributing the properties by using geostatistical algorithms for the properties. Mishrif Formation (unit MB1) in Nasiriya Oil Field was chosen to analyze and model the data for the first eight wells. The field is an anticline structure with northwest- south

Estimation of Excess Properties of Binary Liquids Systems of Tetrahydrofurfuryl Alcohol with Short-Chain Carboxylic Acids at 298.15 K
...Show More Authors

At the temperature 298.15 K, some physical properties such as: refractive indices (nD), viscosities (η) and densities (ρ) were studied in four liquid-liquid mixtures: carboxylic acids (HCOOH, CH3COOH, CH3CH2COOH and CH3CH2CH2COOH) with tetrahydrofurfuryl alcohol (THFA) with the identified configuration set. These empirical data were utilized to estimate the excess molar volumes (Vm E), refractive index perversions (ΔR), viscosity deviations (ηE) and excess molar Gibbs free energy (ΔG*E). Values of Vm E, ηE , ΔG*E and ΔR were plotted versus mole fraction of tetrahydrofurfuryl alcohol. In all cases, the values of Vm E, ηE , ΔG*E and ΔR that obtained in this study were found to be negative at 298.15 K. The excess parameters

The Mesopotamian artist conversed the functions of idols with multi-formation, varied pictured and structural significances sign momentum. Each phenomenon had an idol and each event had an idol. So multiplicity contributes in the enrichment of the Mesopotamian thought by the full and comprehensive familiarity of the characterization of the religious space which reached up to realize the start point of creation and formation and specify the concept of unification in such a way that considered as pagan multiplicity and Atheism according to what brought by most of the previous studies.Such a research as ( The Sign Reading of the Structure of Unification in the Civilization of Mesopotamia) aims to clarify this confusion through decoding the
