In today's corporate landscape, optimizing performance has emerged as a formidable challenge for organizations, often hindered by formidable barriers and psychological factors. This study explores the role of anxiety, stress, and depression in attaining performance among Egyptian construction site workers. The quantitative analysis utilizes cross-sectional data collected from workers working at different construction sites in Egypt. The study concludes with findings from 298 valid cases. Leveraging the structur [...]

In this study, we found that adding catalytic cracking feedstock, vacuum gas oil, and naphthenic acids in the amount of 0.005–0.0075% vol. increased the liquid target fractions, i.e., gasoline and light gas oil. The decrease in the yield of hydrocarbon gas at a practically constant degree of conversion of the raw material indicated a small proportion of the reactions of re-cracking of the resulting products. This also indicated the resource-saving nature of the process, allowing a larger amount of gasoline fraction [...]

Ozone was reacted with the aromatic membrane polyetheretherketone (PEEK) to form oxidized functional groups on the surface to enhance the attraction and transport of protons in fuel cells. Ozonation of unsaturated C-C sp2 bonds in PEEK formed a primary ozonide which dissociated to primarily produce O=C-O/O=C-OH moieties, and the root mean squared roughness factor (Rq) decreased from 7.4 nm, for the untreated sample, down to 3.1 nm. The oxidation of the surface and decrease in surface roughness made the surface incr [...]

Inpatient care is a significant contributor to the health-care costs associated with the treatment of individuals with eating disorders (EDs). This study seeks to better understand the treatment outcomes of individuals with extreme EDs requiring inpatient medical stabilization at specialized medical versus nonspecialized medical units. Patients transferred via air ambulance to ACUTE Center for Eating Disorders and Severe Malnutrition (specialized care) from an outside hospital (nonspecialized care) between January [...]

Many health systems have joined the Age-Friendly Health Systems movement to provide every older adult safe, high-quality care aligned with what matters most. Becoming an Age-Friendly Health System means that hospitals and health care systems reliably use a set of evidence-based practices known as the “4M’s” – What Matters, Medication, Mentation, and Mobility – to provide care for older, disabled and medically complex patients across all care settings. Implementing the Institute for Healthcare Improvement’s (IHI) 4M [...]

The world has suffered a lot during the COVID-19 pandemic, for which nobody was prepared. Due to the lack of appropriate treatment, Indian medicinal plants have alleviated the burden due to their diverse health benefits. It has been observed that certain medicinal plants can effectively enhance immunity against microorganisms and viruses. Numerous scientific studies have supported the above claims. This paper presents the SWOC analysis of Indian medicinal plants for their immunity-enhancing effects so that the medi [...]

We address the Wind Farm Layout Optimization (WFLO) problem and tackle the optimal placement of several turbines within a specific (wind farm) area by incorporating additional aspects of an economically driven target function. With this, we contribute three refinements for WFLO research: First, while many research contributions optimize the turbines' locations subject to maximum energy production or energy efficiency, we instead pursue a strategy of maximizing a profit objective. This enables us to incorporate inne [...]

This study examines the hydrochemical characteristics of groundwater in the Mutoshi mining environment in Kolwezi, Democratic Republic of Congo, addressing gaps in understanding the impact of mining on water quality. Despite the DRC's vast water resources, only 26% of the urban population has access to safe drinking water, with the Mutoshi aquifer, providing over a quarter of Kolwezi's drinking water, facing deterioration due to underlying copper and cobalt-rich geological formations. Groundwater and geological sam [...]

Physical activity (PA) after a colorectal cancer (CRC) diagnosis can improve physical function and quality of life and is associated with decreased mortality rates and longer disease-free survival. The accelerated use of videoconference technology during and following the COVID-19 pandemic offers an opportunity to explore the potential of a virtually supervised intervention to help survivors of CRC increase PA. A two-arm single blind pilot randomized controlled trial of individuals who had completed treatment for C [...]
