An investigation on Libyan olive oil in the western region

 Thirteen Olive oil samples were collected from five different places in the western Libyan region with different cultivation periods. The physical and chemical properties of samples were investigated and classified whether they comply with the Libyan standard specification number 8/2002 or not. The density and refractive index of almost all samples were found within the normal range (0.908-0.919) and (1.4688-1.4705) respectively whereas the chemical properties showed a range of fluctuated values such as peroxide number (11.20-60.40), acidity value (0.737-17.94), saponification number (185.34-199.65), esterification number (173.84-194.36) and iodine number (71.00-94.10). A third of the investigated samples are considered to be of good quality mainly the newer samples.

Catalytic gas-phase glycerol processing over SiO2-, Cu-, Ni-and Fe-supported Au nanoparticles

In this study, we investigated different metal pairings of Au nanoparticles (NPs) as potential catalysts for glycerol dehydration for the first time. All of the systems preferred the formation of hydroxyacetone (HYNE). Although the bimetallics that were tested, i.e., Au NPs supported on Ni, Fe and Cu appeared to be more active than the Au/SiO2 system, only Cu supported Au NPs gave high conversion (ca. 63%) and selectivity (ca. 70%) to HYNE

The prevalence of erectile dysfunction and its associated factors among diabetic patients in the Southwestern Region of Saudi Arabia analytical cross-sectional study

Background: Erectile dysfunction (ED) is a common condition among diabetic patients, significantly affecting their quality of life. This study examines the prevalence of ED and the factors contributing to its occurrence among diabetic patients in the southwestern region of Saudi Arabia. Methods: This analytical cross-sectional study was conducted in randomly selected Primary Healthcare Centers (PHCCs) across the Asir region. The sample included 398 married male Saudi nationals aged 18 years and older, diagnosed with diabetes and attending PHCCs. Data collection involved a standardized questionnaire that included the International Index of Erectile Function (IIEF-5) to measure ED severity and explore related factors. Statistical analysis was performed using SPSS v22, with descriptive statistics including Chi-square tests, independent t-tests, analysis of variance (ANOVA) and multiple regression. Results: Most participants were aged 41–60 years (51.5%), with 55.5% having completed high school or bachelor’s education and 67.8% earning an income of ≤10,000 SR. Most participants (82.9%) have Type 2 diabetes and 21.9% reported smoking. Clinical findings revealed a mean body mass index (BMI) of 28.53, glycemic control was poor, with only 29.1% achieving controlled hemoglobin A1C (HbA1C), while 18.3% had severely uncontrolled levels. In terms of ED severity, mild to moderate dysfunction was most common (29.6%), followed by mild dysfunction (25.1%) and moderate dysfunction (20.4%). Severe dysfunction affected 13.1%, while 11.8% reported no dysfunction. Significant correlations were observed between ED severity and factors such as age, education level, income, duration of diabetes and HbA1C levels (p < 0.05). Smoking status was also significantly associated with ED severity (p = 0.0116), while BMI showed no significant correlation (p = 0.791). Conclusions: Erectile dysfunction is prevalent among diabetic patients in the Asir region, with its severity influenced by demographic and clinical factors. Younger age, higher education, and better glycemic control were associated with reduced ED severity

A Proven Multidisciplinary Approach in Combating Water Flow Potential While Drilling the Asmari Formation in the Western Region of Abu Dhabi

Abstract Water influx from a shallow sandstone formation caused problems in the Western Region of Abu Dhabi. Four wells were drilled in one field and have consistently recorded water flow issues causing Non-Productive Time. This paper looks into the problems recorded in the Drilling Reports and End of Well Reports and provides a technical proposal to combat the problems. The Asmari Formation is encountered in the 26" hole section and is normally cased off with 20" casing. The water influx problems which were in some instances combined with losses not only hampered the drilling operations but also resulted in poor cement jobs requiring remedial actions and challenging well abandonment. The main objectives are; Drill the 26" hole section through the Asmari Formation and cement the 20" casing to surface with no water influx and no mud lossesCementing the 20" casing to surface and eliminate remedial cement jobs The approach described in this paper to achieve the above mentioned objectives was derived from three technical drilling disciplines, Drilling Fluids System, Cement Slurry Design and Operational Practices. The proposed approach was successfully applied to the recent well drilled in the field in 2016/2017. This is illustrated in the case study at the end of this paper which clearly shows that the objectives were fully met.</jats:p
