Chemical polymerization produces polyaniline in two concentrations (0.02,0.05g) at room temperature. The reaction of polymerization was exothermal in nature. The characterization peak was observed in the FTIR range between 1470 and 1560cm-1which defined benzenoid and quinoid ring. To find out the effects Fe2O3, this investigation was carried out with two weights of Fe2O3 (0.05 and 0.02 g). In the experiment part, 32 mice were separated into eight groups, as indicated. The experiment lasted for 35 days. The results showed a significant (P < 0.05) decrease in sperm motility, concentration, percentage of live sperm and testosterone concentration with a significant (P < 0.05) increase in the percentage of abnormal sperm in group treated with PANI-Fe2O3-Cys without magnetic field in comparison with control group. The results also showed a significant (P < 0.05) increase in sperm motility, Relative sperm count of live sperm and testosterone concentration, with a significant (P < 0.05) decrease in the percentage of abnormal sperm in group treated with PANI-Cys and PANI-Fe2O3-Cys exposed to magnetic field in comparison with the samples without magnetic field. The group treated with PANI alone showed an improvement in all parameters studied except the percentage of abnormal sperms which showed a significant (P < 0.05) decrease. Using the alternating magnetic field, it was found that it has a obvious effect on the work of the material PANI- Fe2O3-Cys and PAN-Cys. Thus, it affects sperm motility
Abstract
The research aims to identify the application of corporate governance requirements according to the international standard (ISO 26000:2010) in the National Insurance Company. Strengths and weaknesses were identified to study the current state of this requirement's application in the company under investigation. The descriptive-analytical approach was utilized through a checklist derived from ISO 26000:2010. Several personal interviews and field visits were conducted to understand the extent of application and documentation based on various statistical methods. The results revealed a level of applic

Show MoreAbstract---The aim of the current research is to identify the level of logical reasoning skills in chemistry students at the Faculty of Education for Pure Sciences/ Ibn Al-Haytham for the academic year (2021-2022). The differences in their level of skills according to the gender variable (males and females) and the academic stages (first- second - third - fourth). The descriptive approach was adopted because it corresponds to the nature of the research objectives. The research sample consisted of (400 )students selected in a relatively random stratified way. The researcher constructed a logical reasoning test, which includes (6) sub-skills , which is (proportional - probabilistic- synthetic- deductive- logic- variable adjustment). The psych

dolomitic limestone), marl, shale/claystone, red argillaceous mudstone, sandstone,
carbonate breccias and debris flow, which are arranged in repeated cycles of mixed
siliciclastic-calciturbidites in a range of gravity-flow regime in the Koi Sanjaq area.
Sedimentologic and facies evidences suggest developed marine environment for the
Pila Spi Formation. Facies analysis and associated sedimentary structures including
graded beddings decide turbidity and gravity flow regime origin of the rocks.
Marine environment is supported by the identifying glauconite and fossils types,
which is reported here for the first time rather than lagoon enviro
The objectives of this study were to review the literature covering the perceptions about influenza vaccines in the Middle East and to determine factors influencing the acceptance of vaccination using Health Belief Model (HBM).
A comprehensive literature search was performed utilizing PubMed and Google Scholar databases. Three keywords were used: Influenza vaccine, perceptions and Middle East. Empirical studies that dealt with people/healthcare worker (HCW) perceptio
The current study introduces a novel technique to handle electrochemical localized corrosion in certain limited regions rather than applying comprehensive cathodic protection (CP) treatment. An impressed current cathodic protection cell (ICCPC) was fabricated and firmly installed on the middle of a steel structure surface to deter localized corrosion in fixed or mobile steel structures. The designed ICCPC comprises three essential parts: an anode, a cathode, and an artificial electrolyte. The latter was developed to mimic the function of the natural electrolyte in CP. A proportional-integrated-derivative (PID) controller was designed to stabilize this potential below the ICCPC at a cathodic potential of −850 mV, which is crucial for prote

Coronavirus has affected many people around the world and caused an increase in the number of hospitalized patients and deaths. The prediction factor may help the physician to classify whether the patient needs more medical attention to decrease mortality and worsening of symptoms. We aimed to study the possible relationship between C reactive protein level and the severity of symptoms and its effect on the prognosis of the disease. And determine patients who require closer respiratory monitoring and more aggressive supportive therapies to avoid poor prognosis. The data was gathered using medical record data, the patient's medical history, and the onset of symptoms, as well as a blood sample to test the

New chelating ligand derived from triazole and its complexes with metal ions Rhodium, Platinum and Gold were synthesized. Through a copper (I)-catalyzed click reaction, the ligand produced 1,3-dipolar cycloaddition between 2,6-bis((prop-2-yn-1-yloxy) methyl) pyridine and 1-azidododecane. All structures of these new compounds were rigorously characterized in the solid state using spectroscopic techniques like: 1HNMR, 13CNMR, Uv-Vis, FTIR, metal and elemental analyses, magnetic susceptibility and conductivity measurements at room temperature, it was found that the ligand acts as a penta and tetradentate chelate through N3O2, N2O2, and the geometry of the new complex
