The current article addresses the working memory constraints experienced by older people in caregiving training. Two different approaches aiming to free the older people’s working memory space were discussed. They include multi-modal visual processing and Gc activation. The emphasis was on the theoretical underpinnings of both approaches with empirical evidence from the research and literature to demonstrate their effectiveness in older people’s caregiving training. Further discussion was made with respect to the t [...]

Cyclone separators are widely used in fluid catalytic cracking (FCC) units due to their lack of moving parts and relatively low-pressure drop. However, cyclone separators are prone to erosion-related issues, which is a major drawback. In this paper, a large eddy simulation (LES) of the particle-gas flow in a cyclone separator is investigated using a four-way Euler-Lagrange approach to model inter-particle collisions and the exchange of momentum between particles and fluid. The effects of inter-particle and particle [...]

Iraq’s lakes and rivers are currently exposed to drought because of climatic and political conditions. This study uses satellite images and geographic information systems to display the water depletion and the change in the surface water area of Hamrin Lake. Sentinel-2 imagery of 2018 and 2022 was used to analyze the surface water area changes and water depletion. A comparison was made by studying the changes that happened between 2018 and 2022 respectively. Moreover, a supervised classification technique was [...]

Human milk is not static; it is an invariant fluid that fluctuates in micro and macronutrient composition during feeding. The fat in human milk contributes above half the energy the infant demands. Moreover, fat is one of the most essential nutrients for brain tissue development during infancy. However, the effect of maternal nutritional status, including dietary intake, on human milk fat levels is not well investigated, particularly in developing nations. This study aimed to assess the level of human milk fat and [...]

Fluorescence In-Situ hybridization (FISH) is a sensitive and highly efficient technique commonly used in routine diagnostics. Most of these tests that use analyte-specific reagents are not approved by US Food and Drug Administration (FDA) but are developed by individual test laboratories. There is an emerging demand for prenatal diagnosis of aneuploidies by FISH. Since most of these assays are laboratory-developed tests, it is essential to validate them prior to their use in diagnosis. However, validation procedure [...]

Background: Quality or healthy aging refers to well-being in an older age. In the light of recent changes in the discourse on approaches on positive aging, we aimed to study the way “quality aging” is understood, expressed, and dealt with as a part of contemporary technology assessment (TA), since the nexus between demographic and technological changes has remained a staple topic in TA for at least three decades. Methods: A bottom-up qualitative content analysis was performed to identify the concepts of [...]

The assessment of mental health and mental disorders has undergone extensive exploration within the field of psychology, resulting in various models and approaches. In addition to traditional ways like the Diagnostic and Statistical Manual of Mental Disorders, psychologists have proposed alternative perspectives for evaluating mental health. One such innovative approach is the psychosocial health model, which defines mental well-being as sexual, emotional, social, environmental, cognitive, religious, moral, and spi [...]

This systematic review examines the role of SnRK2 (Sucrose non-fermenting 1-Related protein Kinase 2) genes in Arabidopsis thaliana growth and responses to abiotic stresses. SnRK2 protein kinases are key components of abscisic acid (ABA) signaling and osmotic stress responses in plants. The review synthesizes findings from numerous studies on how different SnRK2 genes regulate Arabidopsis growth, development, and stress tolerance at various life stages. Key topics covered include SnRK2 functions under environmental [...]

This work demonstrates the possibility of implementing a technology that allows profitable value to be drawn from the meat waste from retail stores. Protein hydrolysate, collagen and fatty acids were recovered from meat waste through enzymatic hydrolysis using a mixture of enzymes: a protease (Alcalase) and a lipase (Resinase). Enzymatic hydrolysis was studied by response surface methodology (RMS). Four independent variables were used to study the response variables. The analysis showed that all factors including p [...]

In this paper, the primary aim is to look at the fundamental melting/solidification processes of polyethylene glycol 1500 (PEG 1500) for energy storage - insulation to prolong the cooling time of pipelines in unexpected shut-down conditions, prevent/minimize the wax deposition, and hydrate formation. Polyethylene glycol 1500 was selected because its melting temperature is >317 K making it a suitable candidate as lagging material to prevent wax deposition and hydrate formation in subsea oil pipelines. Experim [...]
