Inorganic Geochemistry and Origin of Bitumen Intruded in Euphrates and Fatha Formations in Hit Area, Western Iraq
...Show More Authors

The content of redox sensitive trace element (V, Co, Ni, and Mo) in the bituminous limestone of the Euphrates Formation (E. Miocene) and bituminous gypsum of the Fatha Formation (M. Miocene) in the Hit Abu-Jir village area, Anbar governorate were determined using Inductively-Coupled Plasma Mass Spectrometer (ICP-MS), in order to infer the origin of the hydrocarbon and the depositional conditions of the organic matter. Hydrocarbons species by using FTIR technique was identified as aliphatic, aromatic compound, hydroxyl acids, hydroxyl group, sulfoxide and sulfur. Bitumen occurrences in these formations is a result of the hydrocarbon seepages that moved up under high pressure along the Abu-Jir fault Zone, and then were intruded in the lime

Histological study of the Isotretinoin drug effect on the intrauterine prenatal development in the pregnant mice
...Show More Authors

The isotretinoin drug is 13-cis-retinoic acid, is the treatment of severe acne and some skin cancers and used for dermatological conditions, this study was designed to detect the toxic role of the isotretinoin on the intrauterine development after implantation in albino mice during pregnancy. There are very little studies which indicating the side-effect of this drug on intra-uterine growth, so in the present research we tried to study the toxic effect of isotretinoin on the endometrial changes of uterus during the 2nd. and 3rd. trimester of gestation in pregnant mice after treatment with single chronic dose of the Isotretinoin drug (20 mg/B.wt) from first day of gestation until 21 days the last day of gestation.

Phytoplankton, as one of the most important primary producers in aquatic ecosystems, has been widely used to indicate the health of ecosystems. Nine physico-chemical parameters of water, as well as the phytoplankton community, of Al-Chibayish marsh were studied. Samples were collected from four sites and analyzed every two months from January to October 2019.

    Seasonal variations in physical and chemical properties were observed at all sites during the study period. The results indicated that 154 species of phytoplankton were recorded. The highest percentage of species was recorded to be 64.28% for Bacillariophyceae (diatoms) (Centrales 3.24% and Pennales 61.03%), followed by Chlorophyceae (16.23%), Cyanophyceae

     Diabetes mellitus is a form of metabolic disorder where patients are incapable to organize glucose metabolism. The most common types are Type I and Type II, constituting about 10% and 90% of cases, respectively. The cause of type I diabetes, which usually spreads in children and adolescents, is the disability of the endocrine system to produce insulin. On the other hand, The most common type of diabetes,  type II diabetes, is often presented in adults. It is usually presented as a collection of insulin deficiency and insulin resistance. This work was done to estimate the count of microbiota in diabetics to find an appraoch for detection and follow-up treatment. The count of two types of bacteria Lactobac

Heavy metal contamination comprises a great concern in the environment. A magnetic study combined with heavy metal analyses was performed in the Sawa Lake in Al-Muthanna governorate (southern Iraq). Concentrations of selected heavy metals (Cr, Fe, Ni, As and Pb) have been measured and magnetic susceptibility (χ) of sediment samples collected from the lake bottom was calculated.

The results confirmed that a cement plant, which is located less than two kilometers away from the lake has no contamination levels on the lake’s sediments. No enhancement in the magnetic susceptibility was observed. X-ray florescence (XRF) was performed for heavy metal analyses.

A Comparative Study on Meta-Heuristic Algorithms For Solving the RNP Problem
...Show More Authors

The continuous increases in the size of current telecommunication infrastructures have led to the many challenges that existing algorithms face in underlying optimization. The unrealistic assumptions and low efficiency of the traditional algorithms make them unable to solve large real-life problems at reasonable times.
The use of approximate optimization techniques, such as adaptive metaheuristic algorithms, has become more prevalent in a diverse research area. In this paper, we proposed the use of a self-adaptive differential evolution (jDE) algorithm to solve the radio network planning (RNP) problem in the context of the upcoming generation 5G. The experimental results prove the jDE with best vecto

The influence of bias current on the bandwidth of chaotic signals in semiconductor lasers by optical feedback has been studied experimentally and numerically. The measured data reveal that the bandwidth increase when the system becomes chaotic and this chaotic signal has a broadband spectrum so it can be used as a carrier for the quantum key. Mixing chaotic signal and quantum key make a very small change in chaotic bandwidth that does not affect the security of data transmitted.
