In this work, nanostructured BaTiO3 films on silicon and glass have been produced by the pulsed laser deposition (PLD) method at different deposition conditions (different laser fluence (8.2to 10.1 J/cm2 ),different substrate temperatures(25 to150⁰C), and a tandem nanostructured n-BaTiO3/n-CdS/p-Si at a varied number of laser pulses(100-300puls). A homemade-pulsed laser utilizes a deposition (PLD) system comprising a Q-switched Nd: YAG laser operating at a wavelength of 532 nm (second harmonic) with a pulse duration of 7ns.Revealed the formation of crystalline nanostructured BaTiO3 with mixed tetragonal and hexagonal phases, with the 150°C deposit having the highest crystallinity and largest particle size. The BaTiO3thin films were created at different laser fluences (8.2 to 10.1 J/cm2) with a constant substrate temperature of 100°C. There was a noticeable increase in the grain size of the film with an increasing laser fluence. The grown films are polycrystalline and exhibit a combination of tetragonal and hexagonal phases, with the film's crystallinity improving as the laser fluence increases. The optical transmittance of the film decreases as the substrate temperature increases and decreases with an increase as the laser fluence increases. Photoluminescence (PL) studies show emission peaks at 477, 574, 561, and 380 nm for BaTiO3 films deposited at 8.2, 8.9, 9.5, and 10.1 J/cm2, respectively. The Hall coefficient of the films was negative, indicating that the films are n-type. The best performance was observed at a laser fluence of 8.9 J/cm2, with a sensitivity of 9.2 A/W at 500 nm and a detectivity of 4.62×1012Jones. A tandem nanostructured n-BaTiO3/p-CdS/p-Si was successfully fabricated, achieving an external quantum efficiency of 153% and a detectivity of 7.4×1012 Jones at 100 pulses.

In this thesis, first we apply a mathematical model based on using the optimization problem's implementation as working procedure to modeling cooperation among power stations and fuel supply producers. Secondly, we use the cooperative game to show the potential cost in case of cooperation through an optimization algorithm to find the most feasible solution using Python program as working procedure. Consequently, based on the important and interaction indices-based optimization algorithm, we employ an application of the methodology to a study case for the fuel supply and electric power production in the Wassit thermal station to demonstrating cooperation benefits between power stations and fuel suppliers which fosters strategy formulation in electrical power management. Experts will greatly benefit from the outcomes of the suggested methodology's testing as they work to refine future electrical power management systems' organised techniques.

This thesis presents an in-depth investigation into the physical properties of SnO2- based photoanode electrodes used in solar cells, prepared using various SnO2 concentrations. The study involves a comprehensive analysis of the structural, morphological, and chemical properties of the materials using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). The results show that the crystallinity and lattice parameters of the materials are consistent across different SnO2 concentrations, while the particle size and surface characteristics vary with SnO2 concentration. The photoluminescence (PL) spectroscopy analysis reveals a decrease in intensity with higher SnO2 concentrations, indicating a weaker interaction between the dye and SnO2. The performance characteristics of the Dye-sensitized Solar Cells (DSSCs) are analyzed in terms of short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF), and efficiency (η). The results show that the cell with the highest SnO2 concentration exhibits the best efficiency. This study provides valuable insights into the physical and chemical properties of SnO2 nanoparticles and their potential applications in solar energy conversion. The experimental results constitute a comprehensive evaluation of the performance and characteristics of the photoanode electrodes in solar cells, contributing to the ongoing research in renewable energy technologies.

One hundred ten RA patients (13. 63 % male, 86.36% female) with a mean age of 23.8±6.8 years and while forty were apparently healthy control individuals with no signs or history of any autoimmune diseases or malignancies were involved in this study that was conducted in the period between Sep.2022 to Jan. 2023. The Patients divided into three subgroup: (1) biological treatment subgroup (consisted of thirty -eight patients on the bDMARDs treatment), (2) conventional cDMARD subgroup [thirty - eight patients received Methotrexate (MTX)] and (3) combined DMARD subgroup (thirty –four patients had received biology and chemotherapy). The human anti citrullinated peptide antibodies (ACPAs), human anti acetylated peptide antibodies (AAPAs), human acetylated Lysine antibodies (AcLys), human anti acetylated ornithine antibodies (AcOrns) were determined by Enzyme Linked Immunosorbent Assay (ELISA) and Zinc, Copper, LDH and alkaline phosphatase levels were used to measure by spectrophotometer in the serum for RA patients and apparently healthy controls. The results reveal that a high significant increase in prevalence of ACPA in RA more than apparently healthy. There are three acelyted peptide antibodies (AAPA, AcLys and AcOrn) are highly prevalent in RA and occur also independently of RF and ACPA. Moreover, high significant decrease difference in the serum level of AcLys (P<0.001) in chemotherapy group in comparison to other subgroup as well as a significant decrease (p=0.0149 ) in the serum levels of AcOrn between Biology vs. Chemotherapy RA patients subgroups. Significant decrease in serum Zn levels in healthy control compared to the sub group of RA patients. A high significant increase in serum Cu levels in sub group of RA patients compared to the healthy control. Moreover, High significant level of LDH in RA compared to healthy control and high significant decrease LDH in biology subgroup compared to other treatment subgroup of RA. the positive correlation between ACPA with AAPA, AcLys and with dieses activity score 28 (DAS28). In conclusion, the evaluating of autoantiody (ACPA,AAPA,AcLys, AcOrn) in RA and multiple AAPA reactivity increased the specificity for RA, suggesting high diagnostic value of AAPA testing. Furthermore, Cu and LDH as a marker for inflammation in RA.
