EFFECT AMBIENT OXIDATION ON STRUCTURAL AND OPTICAL PROPERTIES OF COPPER OXIDE THIN FILMS

The structural, optical properties of copper oxide thin films ( CuO) thin films which have been prepared by thermal oxidation with exist air once and oxygen another have been studied. Structural analysis results of Cu thin films demonstrate that the single phase of Cu with high a crystalline structure with a preferred orientation (111). X-ray diffraction results confirm the formation of pure (CuO) phase in both methods of preparation. The optical constant are investigated and calculated such as absorption coefficient, refractive index, extinction coefficient and the dielectric constants for the wavelengths in the range (300-1100) nm.

Prevalence of hydatid cyst in human and animals in Sulaimaniya city and Saedsadq distract

Background: Hydatid disease is widespread and considered endemic in the Middle East and the Mediterranean, Iraq is one of the countries with a high endemicity of this
disease.
Objectives: The aim of this study is to diagnose hydatidosis and to identify the prevalence in human and animals in two different areas Sulaimaniya governorate
which include Sulaimaniya city and Saedsadq district.,
Methods: Seroepidemiological survey was conducted by using enzyme-linked immunosorbent assay (ELISA) and Indirect Haemagglutination IHA to detect anti
Echinococcus granulosus antibody in random blood samples (536) of different sex, ages, and occupation out patients, in Sulaimaniya and Saedsadq. In the animal study

Analysis of Different Hand and Finger Grip Patterns using Surface Electromyography and Hand Dynamometry

Recording an Electromyogram (EMG) signal is essential for diagnostic procedures like muscle health assessment and motor neurons control. The EMG signals have been used as a source of control for powered prosthetics to support people to accomplish their activities of daily living (ADLs). This work deals with studying different types of hand grips and finding their relationship with EMG activity. Five subjects carried out four functional movements (fine pinch, tripod grip and grip with the middle and thumb finger, as well as the power grip). Hand dynamometer has been used to record the EMG activity from three muscles namely; Flexor Carpi Radialis (FCR), Flexor Digitorum Superficialis (FDS), and Abductor Pollicis Brevis (ABP) with different

The most prominent philosophical and rhetorical concepts in the perspective of philosophers and theologians

     This research aims to clarify and define the most important philosophical and rhetorical concepts to which many philosophical and rhetorical issues refer، since they have an effective role in the diversity and difference of intellectual schools، which are indispensable in proving major dogmatic issues، such as the concept of (existence، being، essence، and authenticity). Existence or Essence in contrast to the consideration of the other concept)، because it is one of the complex concepts and common words that carry different connotations among thinkers.

   And from (the rule of judging something is a branch of its perception)، the researchers began to define these concepts، as evidence of the sincerity of perce

Iraq after war and strategy of reconstruction : Analytical study in reality and future horizon

Abstract (Iraq post – war reconstruction strategy: analytical study in fact and future prospects.) There search aims at identifying the causes of internal instability in Iraq from the political ,economic , social and security aspects , to diagnose the imbalance and to work towards finding real solutions to this . The study also aims at identifying the reconstruction proposals to completely eliminate the organizationof the terrorist advocate, as well as to know. theproblem of research lies in the ability of Iraqi political elites to achieve internal stability and to employ reconstruction proposals at all levels . The hypothesis of the research lies in the equation that the process of building stability (political – economic)and (socia

Synthesis and Characterization of 1,3- Oxazepine and Benz [ 1,2-e][1,3] Oxazepine-4,7-Diones

N- Benzylidene m-nitrobenzeneamines     ( Schiff     bases )  were

prepared by condensation of m-nitroaniline with aromatic aldehydes . These Schiff bases were  found to react with maleic anhydride to give

2-Aryl-3-( m-nitrophenyl )-2,3- dihydro ( 1,3] oxazepine -4,7-diones and with phthalic anhydride to give 2-Aryl-3-( m- nitrophenyl) -2,3

- dihydrobenz [ 1,2-e  ) [ 1,3]  oxazepine -4,7-  diones whicb  were

African landlocked countries problems and outlets in the study and classification of geo-political

Landlocked countries are displayed geopolitical new geo-political and intended to
countries that do not have sea views, a phenomenon present in four continents of the world
are: Africa, Europe, and Asia, and South America and the number arrived at the present time
to the (44) state the largest number of them in the continent it arrived in Africa (16) countries
in Asia (13) countries and Europe (13) In the State of South America two. This phenomenon

Charge density distributions and electron scattering form factors of 19F, 22Ne and 26Mg nuclei

An effective two-body density operator for point nucleon system folded with the
tenser force correlations ( TC's), is produced and used to derive an explicit form for
ground state two-body charge density distributions (2BCDD's) applicable for
19F,22Ne and 26Mg nuclei. It is found that the inclusion of the two-body TC's has the
feature of increasing the central part of the 2BCDD's significantly and reducing the
tail part of them slightly, i.e. it tends to increase the probability of transferring the
protons from the surface of the nucleus towards its centeral region and consequently
makes the nucleus to be more rigid than the case when there is no TC's and also
leads to decrease the
1/ 2
2 r of the nucleus. I

The fundamentalist and news theory between the modernity and excessive modernization of the foreground

Conclusion :

The conflict between the fundamentalist and news theory in the methodology that each of the two schools pursued with the Twelver Shi'a Imamiyyah in deriving the legal rulings from the sources of legislation, especially in the second source, which is the noble hadith and narration after the Holy Qur’an, which is the first source has gone through multiple and complex stages that led This struggle to excess, stress, exaggeration, negligence, neglect and indulgence by each of the two schools in dealing with the noble hadith and narration and in the manufacture of rules and laws and fundamentalist and juristic theories of the process of jurisprudential development of legal rulings where every school believed and proceed

Simulation and Experimental Investigation of Performance and Flow Behavior for Steam Ejector Refrigeration System

The ejector refrigeration system is a desirable choice to reduce energy consumption. A Computational Fluid Dynamics CFD simulation using the ANSYS package was performed to investigate the flow inside the ejector and determine the performance of a small-scale steam ejector. The experimental results showed that at the nozzle throat diameter of 2.6 mm and the evaporator temperature of 10oC, increasing boiler temperature from 110oC to 140oC decreases the entrainment ratio by 66.25%. At the boiler temperature of 120oC, increasing the evaporator temperature from 7.5 to 15 oC increases the entrainment ratio by 65.57%. While at the boiler temperature of 120oC and
