Cfd Analysis Of Hydrodynamic Cavitation Through An Orifice: Influence Of Different Inlet Pressures And Number Of Orifice Holes, Lemthong Chanphavong, Vongsavanh Chanthaboune, Keophousone Phonhalath

ASEAN Journal on Science and Technology for Development

Hydrodynamic cavitation (HC) is considered an energy-efficient process with high potential for utilization in many chemical processes. This study presents a computational fluid dynamics (CFD) analysis of cavitating flow through an orifice with a constant flow area. The Reynolds-Averaged Navier-Stokes (RANS) equations, coupled with turbulence and cavitation models, are employed to capture the complex flow behaviors. The effects of inlet pressures and number of orifice-holes on cavitation behavior are investigated. Result of the numerical simulation is validated with the existing experimental data from the literature. The CFD study revealed that cavitation initiates just behind the inlet edge of the orifice …

Trends in advanced sciences and technology

The composite shear wall with embedded cold formed steel-braces (ECFSB) is a revolutionary pattern of composite wall. It involves of a cold formed steel (CFS) braced frame that is fully immersed within reinforced concrete. The purpose of this configuration is to develop the lateral resilience of the shear wall. The CF steel columns, which are embedded the walls, boost the wall's capability to augment bending forces. Additionally, the steel braces, which are enclosed within the web, enhance the wall's efficiency to resist shear forces. This study investigates the cyclic shear behaviour of compact embedded cold formed steel (ECFS) walls by …

Synthesis And Characterization Of A High Entropy Alloy By Powder Metallurgy Technique, Aya Fawzy, Mohamed Bhlol, Osama Dawood, Ayman Elsayed

Trends in advanced sciences and technology

Synthesis of CuCoFeNiW alloy has been realized by powder metallurgy. Mechanical alloying was used to prepare a high-entropy alloy consisting of Cu, Co, Fe, Ni with and without 10 wt.% W particles. The mixed samples were compacted by a uniaxial press under pressures ranging from 340 to 840 MPa. Green samples were sintered in a vacuum sintering furnace from 1150 and 1300 C. The results have shown that the proposed synthesis route could be used to obtain the alloy with proper transformation and metallurgical properties. Hot forging has effectively increased the hardness of the alloy at all preparation conditions.

Molecular Docking And Adme Calculations Of Structurally Similar Compounds To Anastrozole, Habiba Abd-Rabbo, Somaia Abdel-Rahim, Maha Bakr, Manar Mohammed, Ola Nosseir

Trends in advanced sciences and technology

Aromatase inhibitors prevent the conversion of androgens into estrogens, leading to decreased levels of circulating estrogens. Thus, they are significantly used for the treatment of breast cancer, particularly, in postmenopausal women. Anastrozole, an approved aromatase inhibitor, has gained interest due to its remarkable activity and pharmacokinetics. In this work, small molecules of structural similarity to anastrozole were identified, their ADME-related properties were calculated, and their binding modes to the human aromatase enzyme were evaluated. The calculated properties of the compounds with the highest similarity scores were comparable to those of anastrozole. Six compounds were also predicted to exhibit higher binding …

The heat pipe was developed to enhance heat transfer between the suction and liquid lines of the VCRC. The integration of the heat pipe heat exchanger (HPHE) aims to decrease the compressor duty cycle, which consequently enhances system longevity and reduces energy consumption. The effects of different working fluids and filling ratios in the HPHE on the system performance were examined. Specifically, the impact of these parameters on the refrigeration effect (RE), and overall coefficient of …

Field-Validated Load Modelling And Prediction-Driven Bess Sizing For Oil Drilling Microgrids, Omar H. Abdalla, Alaa A. Afifi, Amr Kassem, Ismail M. Mosaed

Trends in advanced sciences and technology

Diesel-based microgrids serving oil drilling operations are subject to sharp and unpredictable load fluctuations that lead to generator underloading, elevating specific fuel consumption (SFC), and reducing system reliability. Conventional battery energy storage system (BESS) sizing methods typically depend on long-term field measurements and static load assumptions, which fail to capture the real transient nature of drilling processes. This paper develops a framework for BESS sizing that directly integrates a measurement-based machine learning (ML) load prediction model. The adopted model, built using the exponential Gaussian process regression (GPR) technique, has been trained and validated on six months of high-resolution field measurements …

The Impact Of Hip Fracture Multimodal Pain Management On Mobilization And Length Of Stay For Hospitalized Older Adults, Donna Mangruen

Doctor of Nursing Practice (DNP)

Over 95% of hip fractures are related to falling, which equates to approximately 300,000 hip fractures annually in the United States. Poorly managed pain and immobility are risk factors predisposing patients to prolonged hospitalization, permanent disability, and mortality. At an academic medical center, low adherence to the use of a multimodal pain management order set contributes to the sequelae of unfavorable outcomes. Through stakeholder education, this quality improvement project sought to improve adherence to an MPM order set to promote effective pain management, early mobilization, and decreased length of stay. On a surgical unit, surgeons (n=6; 100%) and nurses (n=46; …

Increasing The Uptake Of Arteriovenous Fistulas In Hemodialysis Patients Through A Patient Navigator Pathway, Aderonke Badejogbin

Doctor of Nursing Practice (DNP)

International research has shown that central venous catheters (CVCs) perform worse than arteriovenous fistulas (AVFs) in critical outcomes. The National Kidney Dialysis Outcomes Quality Initiative (NKDOQI) guidelines discourage using CVCs for chronic hemodialysis (HD) and recommend that fewer than 10% of patients undergoing HD for over 90 days use CVCs. AVFs are considered superior to other vascular access methods, offering better longevity, lower infection risk, and reduced mortality and morbidity in most patients. However, a large Veterans Affairs Medical Center Dialysis clinic reported that over 50% of patients were dialyzed via CVCs since January 2022. A literature review conducted from …

Implementation Of A Nurse-Led Service To Improve Venous Ulcer Healing Time And Access, Amaka Akinade

Doctor of Nursing Practice (DNP)

Venous leg ulcerations (VLUs) commonly affect older adults, rural residents, and those with multiple health conditions, leading to high healthcare costs and significant physical and social challenges. The gap between demand for VLU management and available advanced practice providers (APPs) extends healing time and delays access to specialized care, increasing the risk of complications and patient dissatisfaction. This quality improvement project was designed to understand the effect of implementing a nurse-led service using the TIME tool and the Wound, Ostomy, Continence Nurses Association (WOCN) guidelines in VLUs healing time and time to access care over twelve weeks as compared to …
