Performance Evaluation Of Multi-Stage Compressors And Their Impact On Energy Conversion System Efficiency `A Field Study At Thi-Qar Oil Company', Taha Chyad Thajeel

Al-Esraa University College Journal for Engineering Sciences

This paper is a field-based performance assessment of a multi-stage natural gas compressor that is operating in realistic industrial conditions. The data is analyzed using the real operating data taken in a particular oil and gas plant and, therefore, the actual operating data is used to determine the trends of thermodynamic behavior, energy consumption, and efficiency, instead of theoretical or simulation-based assumptions. The analysis was performed phase by phase in order to examine the distribution of pressure ratios, temperature increase and power consumption in the compressor stages. The findings demonstrate that there is a significant difference between the power of …

Effect Of High Protein Diets On Kidney Health Among Athletes And Bodybuilders With Normal Kidney Function, Mustafa Mehdi Alqazzaz, Sajad Abdullah Jleep, Nouran Hussein Mutlaq, Ali Jabbar Jassem

Al-Esraa University College Journal for Medical Sciences

This study emphasizes the effect of high-protein diets(HPD) on kidney function, focusing on key biomarkers (Albumin, Urea, Creatinine & GFR). A HPD is defined as a protein consumption >1.5g/kg per day. Results indicated variations in certain biomarkers among the participants (healthy athletes & bodybuilders with normal kidney function) suggesting potential changes in renal workload. Many studies in resistance-trained athletes focusing at HPD, concluded that there are no harmful effects of HPD on renal health. While no immediate kidney damage was observed, we suggest further investigation into the long -term implications of HPD, particularly for individuals with specific health conditions.

The Pathological Interaction Between Diabetes And Hypertension: Mechanisms And Clinical Complications, Alaa Al-Noori, Ayad Ahmed Al-Taweel, Qater Alnada Jassim Mohammed, Tarik Muhammad Ali, Majeed Mihsin B. Al-Hamdani, Noor Thair Tahir

Al-Esraa University College Journal for Medical Sciences

Among the most prevalent chronic conditions, diabetes and hypertension frequently coexist in a single patient, aggravating vascular problems and hastening the deterioration of target organs, especially the kidneys. By raising intraglomerular pressure, impairing endothelial function, and triggering oxidative stress and inflammation, hypertension directly increases the chance of developing diabetes sequelae, including diabetic nephropathy. Chronic kidney disease advances more quickly when poorly managed hyperglycemia and hypertension combine to cause a decrease in glomerular filtration rate and an increase in urine albumin excretion. Other consequences like retinopathy, neuropathy, and cardiovascular disease are also encouraged by this pathological occurrence. Reducing the advancement of …
