Morphological and optical properties of V2O5:TiO2 thin film prepared by PLD technique

              In this work, pure and doped Vanadium Pentoxide (V2O5) thin films with different concentration of TiO2 (0, 0.1, 0.3, 0.5) wt  were obtained using Pulse laser deposition technique on amorphous glass substrate with thickness of (250)nm. The morphological, UV-Visible and Fourier Transform Infrared Spectroscopy (FT-IR) were studied. TiO2 doping into V2O5 matrix revealed an interesting morphological change from an array of high density pure V2O5 nanorods (~140 nm) to granular structure in TiO2-doped V2O5 thin film .Transform Infrared Spectroscopy (FTIR) are used to analyze structural properties of as-deposit. The transmittance and absorption of each film, in the spectral range 300 to 1100 nm, were measured from which the optical constants (Refractive index, Absorption coefficient, Extinction coefficient and Energy gap) were determined .The energy band gap of the films was found to be change from (2.38 to 2.9) eV when the concentration of TiO2 increases from (2.78 to 2.9 ) eV The results showed a significant improvement in the transmittance and refractive index in TiO2 doped V2O5 thin films .All measured values were in consistent with other previous studies.

The influence of the political and social socialization in the trend towards extremism

The research deals with the impact of the nature of social and political formation in the orientation towards extremism through tracking the institutions and beliefs that the individual is going through. The role of the family, the group, the school, education, and religion has been touched upon in acquiring the trends of extremism, whether publicly or covertly, Focusing on the social and economic contexts that are an incubator environment for extremism supported by the form of the group and the beliefs it espouses, whether direct through religion or indirectly through the nature of education, this study relied on political literature that addressed this The topic, which focused on the phenomenon of extremism that swept the world recentl

Music and Singing in The Heritage of Baghdadi The 1930s is a Model

Music and singing are always associated with the movement of society and the emergence of cultural and artistic activities other.
The social and political transformations of the 1930s helped to disseminate the study Music and music in the city of Baghdad and across Iraq This is the beginning of a new era of musical art alongside other arts.
While achieving musical arts A new step was advanced by publishing a technical study among the younger generation they were looking for to contribute to the musical field On the other hand, the city of Baghdad during the period of research many musical and musical performances Egyptian teams have provided many artistic activities and events which have had a significant impact on the development

Hydrogeologic Conditions of Mulussa Aquifer Between Rutba and Dhabaa in Al-Anbar Governorate

     Rutba area is located in Al-Anbar Governorate - West of Iraq. Hydrogeological investigation calculation of Mulussa aquifer between Rutba and Dhabaa is carried out. The groundwater moves in directions of (NE, E and SE) influenced by depletion process in the amount of hydraulic gradient ranged between (0.0000416 - 0.008036). The groundwater flux (V) and groundwater pore velocity (U) are reached (0.00451) m/day and (25.02) m/day, respectively.  Mulussa aquifer is carbonate beds, where represents confined aquifer conditions. The values of transmissivity, permeability and storage coefficient are ranged between (0.507 – 250) m2/day, (0.00547 - 3.05) m/day and (9.65 x 10-5 - 2.64 x 10-4

The Preparation of some New Mannich and Shiff bases derived from 2-Mercaptobenzimidazole

The present work involved two steps: the first step include Mannich reaction was carried out on 2- mercaptobenzimidazole using formaldehyde and different secondary amine or amide to gives the compounds(2-16). The secnd step include preparation of (Ethylbenzimidazoly-2-mercaptoacetate)(17) from the reaction of 2- mercaptobenzimidazole with ethylchloroacetate than prepared hydrazide derivative[18]from reaction of compound(17) with hydrazinehydrate. Followed Preparation of shiff bases(19-24) and there reaction with mercaptoacetic acid to give a new compounds containing thiazolidinderivetives(25-30).Structure confirmation of all prepared compound were proved using FTIR and element analysis (C.H.N.S) and mesurmentedmelting poi

Guillian Barré Syndrome in a sample of Iraqi Children: Seasonal and sex variation

Background: Seasonal variation and gender preponderance have not been adequately studied in Guillain-Barre syndrome (GBS).
Objective: This study aims to evaluate the seasonal variation and sex preponderance in children with Guillian Barré Syndrome.
Patients and methods: A cross sectional study was carried out by reviewing wards’ registry of all cases with Guillian Barré Syndrome admitted to Children Welfare Teaching Hospital during a 10-year period (1999 - 2008). Age, sex, seasonal distribution, residence and outcome were analysed.
Results: Guillian Barré Syndrome was diagnosed in 217 (126 boys, 91 girls) patients and the annual hospital rate of admission was 22.9 /100000 children. There was increase annual incidence from 1

Oscillations of First Order Linear Delay Differential Equations with positive and negative coefficients

Oscillation criteria are obtained for all solutions of the first-order linear delay differential equations with positive and negative coefficients where we established some sufficient conditions so that every solution of (1.1) oscillate. This paper generalized the results in [11]. Some examples are considered to illustrate our main results.

Synthesis of novel Nucleoside Analogues from Imidizoline and Evaluation their Anti microbial Activity

In this research some new nucleoside analogues were synthesized. Starting from α-D- glucose which was protected to glucose penta acetat α-D- glucose pyronside (1). Which was converted to active form 1-bromo protected sugar (2) as a sugar moiety. The base moiety 2-substituted imidazoline (3,4) was prepared from condensation of ethylene diamine with two kind of aromatic aldehydes, which were subjected to amino alkylation via Mannich reaction forming new nucleaobase derivatives (5-10). Condensation of nucleobase with bromo sugar through nucleophilic substitution of anomeric carbon with nitrogen forming new protected nucleoside analogues (11-16). De blocking of these nucleoside analogues with sodium methoxide in methanol afforded our targe

Assessment of Electromagnetic Pollution in Some Hospitals and Schools in Al-Najaf City

The tremendous benefits of using cellular phones, which began to increase and unprecedented spread worldwide last decade, were accompanied by harmful effects on the environment due to the increase in electromagnetic radiation (EMR) which be emitted from mobile phone towers. This effect on humans, animals, and plants, which is considered a form of environmental pollution, was sensed by developed countries and Environmental protection organizations. These countries have established restrictions and enacted laws to reduce their negative impact on living beings. The field survey included six major hospitals and 38 schools were distributed over the central neighbourhoods in Al-Najaf city. The results showed that power density (PD) measurement
