Abstract: In this study, we introduce a novel approach to the solution of a nonlinear Volterra -Fredholm integral equations by applying the Adomian decomposition method under the effect of the Abaoub- Shkheam transform. We demonstrate the existence and uniqueness of the solution in Banach space and illustrate this idea with an example.

This study provides a comprehensive evaluation of the compliance of key Libyan government websites with the Web Content Accessibility Guidelines (WCAG) 2.2, the latest international standard for digital accessibility published in October 2023. The assessment focuses on the nine new success criteria introduced in WCAG 2.2, which aim to improve accessibility for users with low vision, cognitive, and motor disabilities. By conducting thorough automated and manual testing, this research identifies the specific strengths and weaknesses of the evaluated websites in meeting WCAG 2.2 requirements at the A, AA, and AAA levels. The findings reveal significant areas for improvement across the government's online presence and provide actionable recommendations for Libyan institutions to enhance their digital accessibility efforts and create a more inclusive online environment for all citizens.

A type of EOR, secondary production includes water flooding and gas injection. Normally, gas is injected into the gas cap and water is injected into the production zone to sweep oil from the reservoir. A pressure-maintenance program can begin during the primary recovery stage, but it is a form of enhanced recovery. The main purpose of this report is to investigate the effect of the reservoir rock compressibility on oil recovery factor during gas injection. The problem statement of this study is firstly, as the reservoir oil and gas production under primary conditions, causes the reservoir pressure to decline. Secondly, A gas injection is required to re-energize or “re-pressurize" the reservoir. The main objective of this project is to investigate the effect of the reservoir fluid densities on oil recovery factor during gas injection. By using ECLIPES Software, we model the data and find out the best prediction of gas injection that is suitable for the available field data. It is proven that the optimum oil production is by injection a high amount of injection rate. The highest increase in percentage of the total gas production is when an injection of 54 MMSCF is 0.58 %. The higher the compressibility value of the rock, will give the higher the rate of oil and gas production. The relationship between oil rate, gas rate, pressure, and oil recovery factor are directing the compressibility of rocks is a direct relationship.

Daily incidents significantly impact the workflow of ambulance and healthcare personnel, whose critical role involves providing immediate medical treatment and facilitating transportation to hospitals. This study presents the design of a medical expert system aimed at enhancing first-aid response in ambulances and educating users on fundamental first-aid principles. The proposed system integrates a comprehensive knowledge base that catalogs disease symptoms and corresponding treatments, functioning similarly to a medical professional's guidance. While the system relies on pre-programmed symptoms, it allows for the continuous addition of new symptoms and diseases, ensuring adaptability in emergencies. This expert system is particularly beneficial for novice healthcare providers, equipping them with reliable diagnostic support and improving patient outcomes during medical emergencies.

Seven sedimentary rocks and seven crude oils undertook a geochemical analysis to describe their organic matter type and

then tag the Paleoenvironments based on the organic matter. The samples were collected from B1-NC151, A1-NC58, P1-

NC1, E1-NC174, D1-NC151, H29-NC115, and D1-NC174 boreholes, located in Murzuq Basin. The study was established to

understand life forms in the ecosystem based on biomarkers that biochemical techniques recognized. Microscopy was used

for kerogen typing and Spore Color Index reference. Organic matter (EOM) was extracted from cutting samples. Furthermore,

hydrocarbons were saturated and aromatic fractionated from the samples to investigate using Gas chromatograph system.

Spore color index (SCI), range between 1.5-3.5, Amorphous organic matter (AOM) from 42 to 95 percentage, Phytoclasts %

were 4-15.5, and Palynomorphs % range 0.5 to 7.5. The percentage of Carbon 85.66-86.29, Hydrogen 13.16-13.73, Nitrogen

0.06 -0.27, and Sulfur 0.31-0.70, besides wax were measured, ranging among 1.3 to 6.0 %. Pristine/n-C17, Phytane/n-C18,

Pristine/Phytane, carbon preference index measurements (CPI) and DBT/P as saturated hydrocarbon ratios from whole oil

chromatographs were established. Tricyclic terpanes, hopanes and n-alkanes were distinguishing as the most important oil

biomarkers that reserved the characteristics in the Paleoenvironments. 

This paper investigates the resonance phenomenon and modal characteristics of a screw air compressor base frame in the cement manufacturing industry. Numerical analysis and data comparison techniques were used to identify and analyze the resonance issue in a specific compressor at Souq Al-Khamis Cement Factory. The research begins by studying the natural frequencies and mode shapes of the compressor base frame through Finite Element Method (FEM) using the ANSYS Workbench. Practical measurements are conducted using the PHYPHOX App Vibration Analyzer to obtain vibration data from the compressor. The findings of this study contribute to understanding the resonance phenomenon in screw air compressors and provide valuable insights for improving the design and maintenance of compressor base frames in the cement manufacturing industry. By identifying the relationship between excitation frequencies and natural frequencies, measures can be taken to mitigate resonance-related vibration problems and ensure the reliable operation of cement production equipment.

Blades are the very important components of wind turbines in order to convert wind energy to mechanical or electrical energy. Therefore, the aerodynamic forces acting on the horizontal wind turbine blades have an important role in their performance. The objective of this paper is to investigate the aerodynamic characteristics and power generation properties for a NREL PHASE VI wind turbine blade. For this purpose, an analysis procedure based on the Blade Element Method (BEM) is demonstrated for a horizontal-axis wind turbine model (HAWT), and the methodology approach is discussed in detail throughout this paper. In this study, a Math Lab code has been developed for analyzing a model of Horizontal-Axis Wind Turbine (HAWT) in order to display aerodynamic behaviour on the blade. The NACA S809 airfoil was selected for the analysis of the wind turbine blade, where the tip and root losses proposed by Prandtl are also executed. The calculated results are validated using Q-Blade commercial software at rated wind speed of 10 m/s and show that the BEM is a good method of aerodynamic investigation of a HAWT blade

Introduction: Diabetes is a common condition among pregnant women, and a high glycated haemoglobin (HbA1c) level can indicate poor outcomes for both the mother and the fetus. This report presents a case of an unknown diabetic primigravida with a significantly elevated HbA1c level, which resulted in severe complications during pregnancy and adverse fetal outcomes. Case Study: A 37-year-old primigravida was referred to the emergency obstetrics and gynaecology clinic, where she reported a notable decrease in fetal movements and feelings of lethargy. Laboratory tests revealed a significantly elevated blood sugar level. After assessing fetal well-being, the decision was made to terminate the pregnancy at 33 weeks and 2 days due to severe fetal distress. Immediate treatment was initiated to control the high blood sugar levels. The outcome was the delivery of a preterm boy who presented with multiple biochemical imbalances and required admission to the neonatal intensive care unit (NICU). Conclusion: Improving hyperglycemia and glycated haemoglobin levels to lower than the upper normal limits during both the preconception and post-conception phases can significantly reduce morbidity and mortality for mothers and their fetuses.
