Thesis Abstract

Abstract Active sediments along a 90 km section of Greater Zab River (GZR) in Kurdistan Region/ Iraq were analyzed for their major, trace, and rare earth elements contents to investigate their provenance, weathering at the source area, and tectonic setting. The enrichment of sediments with transition elements (Co, Cr, and Ni), the bivariate (Zr/Sc vs […]

Summary Three algal species, Tetradesmus nygaardi (MZ801740), Scenedesmus quadricauda (MZ801741) and Coelastrella sp. (MZ801742), with two species of fungi Aspergillus niger (ATCC 16404) and Candida albicans (ATCC 10231), were used for remediation of heavy metals and water quality improvement as biological approach, The wastewater samples collected from Dhahiba village near Erbil wastewater channel. The river receiving the effluent from Erbil wastewater channel. The mean depth and

Summary      The World Health Organization advises against using the antiviral Remdesivir medication for treating severe COVID-19 infections due to its potential toxicity. The efficacy and toxicity of many medications are influenced by ATP-binding cassette (ABC) transporters, which play a significant role in the transport of several drugs used to treat numerous disorders. Therefore, this

Summary This study was carried out in the laboratories and greenhouse of the Biology Department, College of Science, Salahaddin-Erbil University, and the laboratories of the Research Center at Erbil Polytechnic University, from April 21st, 2019 to July 26th, 2020. The study consisted of three experiments, two of them are factorial (2x3x3) experiments, and the third

Abstract In this study, the hydrothermal method was used for growing and characterizations of Titanium Dioxide (TiO2) nanorods on the Fluorine-doped Tin Oxide (FTO) coated glass substrate at some different preparation conditions of the hydrothermal process at a constant reaction time. The hydrothermal growth temperature, precursor solution of Titanium Tetra Chloride (TiCl4), hydrochloric acid (HCl)

Summary The thesis includes four main chapters: Chapter One: provides a general overview of some analytical methods that can be used for simultaneous determination in multicomponent mixtures and, the theory and application of those methods that are used in this work, such as the H. point standard addition method, Q-absorption ratio method, and derivative methods. Chapter

Summary The present work deals with green condensation of two classes of aromatic heterocyclic compounds with various substituted aromatic aldehydes; the first class involves condensation of 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one known as 4-aminoantipyrine (37) with ten different substituted benzaldehydes (17) including (benzaldehyde,2-chloro-benzaldehyde, 2,6-dichlorobenzaldehyde, 2-fluorobenzaldehyde, 4-fluoro-benzaldehyde, 4-hydroxybenzaldehyde, 4-methoxybenzaldehyde, 3,4-dimethoxybenzaldehyde, 4-nitrobenzaldehyde, and 4-hexyloxybenz-aldehyde) to prepare 4-aminoantipyrine Schiff bases. The second

Summary                                 The kinetic studies for copper-catalyzed homocoupling reaction of phenylboronic acids have been successfully carried out in an aqueous micellar medium under environmentally benign conditions (water as a solvent, micelle to help solubilize hydrophobic adducts). In this study cetyl trimethyl

Summary Cardiovascular disease is the main reason for mortality in developed and developing nations. Atherosclerosis is the major source of morbidity and mortality, more people died in the Kurdistan region of cardiovascular diseases. Advanced glycation end products (AGEs), such as Nε-(carboxymethyl)-lysine (CML) and pentosidine (PTD) are implicated in vascular disease. This study aims to investigate

SUMMARY Unlike T cells, Natural Killer (NK) cells are negative for T cell receptors (TCRs). The functional TCR complex protein consists of TCRαβ chains and downstream signaling subunits of CD3δ, CD3γ, CD3ε and CD3ζ chains. T cells are positive for all, while NK cells lack all these polypeptides except CD3ζ. NK92 cells were transduced by
