On (σ,τ)-Derivations and Commutativity of Prime and Semi prime Γ-rings

Let R be a Г-ring, and σ, τ be two automorphisms of R. An additive mapping d from a Γ-ring R into itself is called a (σ,τ)-derivation on R if d(aαb) = d(a)α σ(b) + τ(a)αd(b), holds for all a,b ∈R and α∈Γ. d is called strong commutativity preserving (SCP) on R if [d(a), d(b)]α = [a,b]α(σ,τ) holds for all a,b∈R and α∈Γ. In this paper, we investigate the commutativity of R by the strong commutativity preserving (σ,τ)-derivation d satisfied some properties, when R is prime and semi prime Г-ring.

Electrical glow discharges and plasma parameter of planar sputtering system for silver target

DC planar sputtering system is characterized by varying discharge potential of (250-2000 volt) and Argon gas pressures of (3.5×10-2 – 1.5) mbar. The breakdown voltage for silver electrode was studied with a uniform electric field at different discharge distances, as well as plasma parameters. The breakdown voltage is a product of the Argon gas pressure inside the chamber and gab distance between the electrodes, represent as Paschen curve. The Current-voltage characteristics curves indicate that the electrical discharge plasma is working in the abnormal glow region. Plasma parameters were found from the current-voltage characteristics of a single probe positioned at the inter-cathode space. Typical values of the electron temperature an

Correlation between Serum Sialic Acid Level and frequent risk factors of Diabetic Retinopathy

Background: Diabetic retinopathy is an important complication of diabetes mellitus. It is supposed that elevated sialic acid in diabetes mellitus plays an important role in diabetic retinopathy. This study investigated serum total sialic acid levels related to glycemic control, blood pressure, retinopathy, and serum lipid level in diabetic retinopathy patients.
Patients & Methods: Type 2 diabetic patients aged (56.47±10.68) years were recruited for the study. Fasting venous blood samples were collected from 132 diabetic subjects of whom 79 without retinopathy and 53 were diabetic with retinopathy. All the blood samples were processed for serum total sialic acid (TSA), fasting serum glucose (FSG), HbA

Evaluation of Paromomycin Loaded Chitosan Nanoparticles and Oxidative Stress Activities against Entamoeba Histolytica
Abstract<p>This investigation was carried out to estimate the antiparasitic potential of chitosan nanoparticles loaded with paromomycin against <italic>Entamoeba histolytica</italic> infected. After rats inoculated orally in a dose 10<sup>3</sup> viable cysts for acute infection; then treated with paromomycin, chitosan nanoparticles as a single or combined therapy given for seven days. Stool examination revealed a significant decrease in the number of <italic>Entamoeba histolytica</italic> cysts in all treated infected rats compared with infected non-treated. Combined treatment provided better results than single treatment. The best effect was observed in the group </p> ... Show More

Rooting non-violence in the Holy Quran And models of the Prophet application

The term “non-violence” is a means of political, social, and advocacy that excludes force in reaching its objectives, and lacks infringement of the rights of non-violence. The policy of non-violence is a beautiful logic of the whole of Islamic creation, in that it is an integral part of the whole structure of Islam and it is a policy of brilliant and brilliant saying in the Almighty: `` Neither level nor good or bad, pay what is better, If that between you and him enmity as if he were intimate guardian (Suratvsalat, verse: 34. Has According to the prophet of Islam, it means that God gives to kindness (kindness) what does not give to violence (Sunan Abu Dawood, 4/255). These terms accurately communicate what is meant by violence and n

Identification of an unknown person using Y-chromosome markers and mitochondrial dna typing

Background: The present article is concerned within the scope of Forensic Medicine, specifically Forensic Genetics. The case was taken care of in the Genetic-Molecular Laboratory of the Odessa Regional Bureau of Forensic-Medical Examinations, in Ukraine, during January and February of 2014.
Objectives: The aim of our work was to identify an unknown person, using the techniques: Y-chromosome markers and mitochondrial DNA typing.
Materials and methods: The materials available for our procedure were: pieces of tissue in paraffin blocks, saved from the corpse of the unknown person; blood from a living male subject, who claimed to be the grandfather, and from two females, allegedly the sisters. From all of them we extracted nuclear DNA

Delayed Recovery of Contrast Induced Kidney Injury Post Angiography: Rate and Risk Factors

Background: Exposure to Contrast media is the third leading cause of hospital acquired acute kidney injury. It follows a predictable time of onset and a less predictable scenario in recovery. This is related to certain factors, but at the end there will be asubstantial association with increased mortality, morbidity, and length of hospitalization.
Objectives: To define the Incidence of persistent contrast induced renal impairment a month after angiography and to define the risk factors for such persistence
Patients and Methods: One hundred and one patients (101) were enrolled in this study. All were referred to the Iraqi Center for Heart Diseases in Baghdad/ Iraq for coronary and/or peripheral vascular angi

Clinicopathological Features and ICD-10 Categorization of Oro-maxillofacial Surgical Biopsies from Sulaimani

Background: Few updated retrospective histopathological-based studies in Iraq evaluate a comprehensive spectrum of oro-maxillofacial lesions. Also, there was a need for a systematic way of categorizing the diseases and reporting results in codes according to the WHO classification that helps occupational health professionals in the clinical-epidemiological approach.

Objectives: to establish an electronic archiving database according to the ICD-10 that encompasses oro-maxillofacial lesions in Sulaimani city for the last 12 years, then to study the prevalence trend and correlation with clinicopathological parameters.

Subjects and Methods:  A descri

Comparison I-V Characteristics of Sb/c-Si and Al/c-Si Junction

  Hetero junctions are fabricated by depositing antimony (Sb) and Al films on n-type single crystal(c-Si) wafers by the method of vacuum evaporation with thickness (0.25µm), with rate of deposition equals to 2.77 Ã…/sec, all samples are annealed in a vacuum for one hour at 473K. The tests have shown that all the films have polycrystalline structure for all Sb films. The barrier heights in (Sb/c-Si) junction was found to be equal 0.825eV, but(Al/c-Si) junction ohmic contact. Current-voltage measurements confirm this behaviour.
