Evaluation and production of predictive maps on the impact of climate factors on the the land cover for the Baghdad city for the period (1999-2021)
...Show More Authors

The general objective of the research is to better understand changes in land cover and their impact on climatic factors by measuring changes in land cover for the Baghdad city for the period 1999-2021 and evaluating changes in land cover and measuring changes in climatic factors (relative humidity and evaporation). This study from 1999 to 2021 and in two different seasons: the April of the growing season and August the dry season. When using the supervised classification method to determine the differences, the results showed remarkable changes, the study showed the spatial variations in LC from 1999 to 2021 as follows: increase in the vegetation and water bodies during April and decrease this in August while the soil and built up decrease in April and increase this in August. As for the influence of climatic factors, an increase in relative humidity during 1999 and 2021 for April, while it decreased during the years 1999 and 2021 for August. While evaporation decreases during 1999 and 2021 for April and increases during 1999 and 2021 for August

A Novel Coating of Orthodontic Archwires with Chlorhexidine Hexametaphosphate Nanoparticles
...Show More Authors

Statement of the Problem. The use of orthodontic fixed appliances may adversely affect oral health leading to demineralizing lesions and the development of gingival problems. Aims of the Study. The study aimed to coat orthodontic archwires with chlorhexidine hexametaphosphate nanoparticles (CHX-HMP NPs) and to evaluate the elusion of CHX from CHX-HMP NPs. Materials and Methods. A solution of CHX-HMP nanoparticles with an overall concentration of 5 mM for both CHX and HMP was prepared, characterized (using atomic force microscope and Fourier transformation infrared spectroscopy), and used to coat orthodontic stainless steel (SSW) and NiTi archwires (NiTiW). The coated segments were characterized (using scanning electron microscopy

Evaluating Petrophysical Properties of Sa'di Reservoir in Halfaya Oil Field
...Show More Authors

The petrophysical characteristics of five wells drilled into the Sa'di Formation in the Halfaya oil field were evaluated using IP software to determine a reservoir and explore hydrocarbon reserve zones. The lithology was evaluated using the M-N cross-plot method. The diagram showed that the Sa'di Formation was mainly composed of calcite (represented by the limestone region) is the main mineral in the Sa′di Reservoir. Using a density-neutron cross plot to identify the lithology showed that the formation mainly consists of limestone with minor shale. Gamma-ray logs were employed to calculate the shale quantity in each well. The porosity at weak hole intervals was calculated using a sonic log and neutron-density log at the reservoir

Potato Phosphorus Response in Soils with High Value of Phosphorus
...Show More Authors

Phosphorus (P) is an element that is potatoes require in large amounts. Soil pH is a crucial factor impacting phosphorus availability in potato production. This study was conducted to evaluate the influence of P application rates on the P efficiency for tuber yield, specific gravity, and P uptake. Additionally, the relationship between soil pH and total potato tuber yield was determined. Six rates of P fertilization (0–280 kg P ha−1) were applied at twelve different sites across Northern Maine. Yield parameters were not responsive to P application rates. However, regression analysis showed that soil pH was significantly correlated with total potato tuber yield(R2 = 0.38). Sites with soil pH values < 6 had total tuber yields,

Numerical Simulation of Thermal-Hydrodynamic Behavior within Solar Air Collector
...Show More Authors

Solar collectors, in general, are utilized to convert the solar energy into heat energy, where it is employed to generate electricity. The non-concentrating solar collector with a circular shape was adopted in the present study. Ambient air is heated under a translucent roof where buoyant air is drawn from outside periphery towards the collector center (tower base). The present study is aimed to predict and visualize the thermal-hydrodynamic behavior for airflow under inclined roof of the solar air collector, SAC. Three-dimensional of the SAC model using the re-normalization group, RNG, k−ε turbulence viscus model is simulated. The simulation was carried out by using ANSYS-FLUENT 14.5. The simulation

Solzhenitsyn's Style of Artistic Research: Опыт стиля художественного исследования А.Солженицыным
...Show More Authors

 Aleksandr Isayevich Solzhenitsyn was born in 1918 in Kislovodsk. His father was educated, and despite his peasantry origin, he got a university degree. Unfortunately, however, Solzhenitsyn could not recognize his father, for he died before his birth.

Solzhenitsyn was accused of being an opponent to the Soviet Union due to his activities of that time. He was exiled to a forced labour camp for eight years, on the surroundings of Moscow. He spent three years in Kazakhstan, and was sent to the life exile. He was set free in 1956. He worked as a teacher in in rural schools in Vladimir and then in Rezhran. 

His greatest works were in the reign of Kherchov, and in 1962 appeared his story under the title of "One day in

Antioxdent, Antifungal Activities of n-Hexadecanoic Acid Extracted from Algae
...Show More Authors

The importance of algae as a natural source of various bioactive compounds continues to grow due to their diverse biological activities. One of such compounds is n-hexadecanoic acid, more commonly known as palmitic acid; it is more lipidous than many algal species. It is one of the most common saturated fatty acids in nature. One can find it in algal, animal, and plant oils and is extracted from numerous natural sources. Its chemical and biological attributes enable its widespread use in the pharmaceutical, food, and cosmetic industries. Numerous studies have found that palmitic acid is effective for fungal activities and does have pharmaceutical and environmental promising antioxidant capabilities.

Emotional Purity among University Students in Light of Selected Variables
...Show More Authors

The study aimed to measure emotional purity, as well as to explore differences in it according to the variables of gender (male–female), academic level (first–fourth year), and field of specialization (scientific–humanities). The study adopted the descriptive-analytical method. The study instrument, a validated Emotional Purity Scale, was applied to a stratified random sample of 300 male and female students from the University of Baghdad. The results indicated that university students generally possess emotional purity. They also revealed significant differences in emotional purity attributed to gender in favor of females, to academic specialization in favor of humanities students, and to academic level in favor of fourth-year
