Recently, renewable energy projects using storage systems have gained significant attention. This innovative technology requires a comprehensive investigation to overcome the technical and economic issues, which are related to optimal storage system capacity and operational requirements. In this study, an extensive battery energy storage system (BESS) sizing method was proposed considering four variables: charging and discharging scheduling, state of charge, BESS rate energy and power capacity, and degradation effe [...]

TiO2 photocatalyst was prepared using cellulase as a biotemplate through a hydrothermal process. The as-prepared catalyst was characterized based on physicochemical techniques and was used to remove As(III) from contaminated water. The cellulase templated TiO2 photocatalyst (TiO2-cellulase) had a large specific surface area, which reached 166.6 m2·g–1. It also had a strong oxidation ability and, thus, behaved well in both photocatalytic oxidation of As(III) and dark adsorption. The pH of the solution h [...]

The escalating prevalence of vision loss due to eye diseases has instigated a quest for innovative therapies, given that conventional approaches often fall short in repairing and regenerating damaged eye tissues, particularly the retina. Stem cell-based interventions have emerged as a promising avenue, with numerous studies in animal models and human trials exploring their potential to enhance visual acuity. Beyond addressing conditions like age-related macular degeneration (AMD) and diabetic retinopathy (DR), stem [...]

Illnesses following the degeneration of the nervous system can occur due to aging or genetic mutations and represent a clinical concern. In neurodegenerative diseases, loss of neuronal structure and functions mainly causes cognitive impairment, representing an increasing social burden. In neurodegenerative diseases, the progressive loss of vulnerable populations of neurons in specific regions of the central nervous system was traced to different pathological events, such as misfolded proteins’ accumulation, abnorma [...]

There is evidence to suggest that older livers regenerate less well and display cellular senescence. Additionally, elderly patients with certain liver diseases have a less favourable course. Chronic liver disease, amongst the elderly, has a significant negative effect upon quality of life and functional independence. Frailty, commonly encountered in geriatric patients, remains a significant negative predictor of physical, psychological, functional and survival outcomes in chronic liver disease.

Non Alcoholic Fatty Liver Disease (NAFDL) is a condition in which an individual suffers from an accumulation of fat in the liver. This is a disease condition with a multifactorial etiology. Some potent causes of such conditions are altered thyroid condition, abnormal metabolism in the body due to aging or menopause, or any other hormonal imbalance. Most of these causes are regulated by genetics, lifestyle, and environmental factors. Menopause comes with tremendous hormonal turmoil in the human body and brings vario [...]

Cytokines are pivotal regulators of immune responses. They are critical in mediating inflammation, recruiting immune cells, and driving pathogen clearance. Among these, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-α) stand out as key players in pediatric immunity, as they exhibit unique expression patterns that reflect the dynamic nature of the developing immune system.

Graphs and nomograms have been obtained, which makes it possible to simplify the calculation procedure according to the proposed meth [...]

Foot reflexology has improved numerous physical and psychological symptoms in patients. The researchers in this study aimed to investigate the effect of foot reflexology on laboratory parameters, intake/output/weight and medication regimen after kidney transplant surgery. The research was a secondary analysis of a parallel randomized controlled trial. The research included patients who were admitted to the transplantation ward. The stratified randomization approach divided 53 eligible patients into two groups: foot [...]

In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies were conducted on zeolite ZSM-5, zirconyl chloride modifier ZrOCl2∙6H2O, and modified zeolite ZSM-5-ZrO2, which was calcined at temperatures of 200, 400, and 550°C. The results revealed that the phase composition of modified ZSM-5-ZrO2 zeolite samples varied depending on the calcinatio [...]

Despite the increase in use and interest in mobile devices by older adults, to date, there is still limited research carried out to better understand older adults’ usage and needs as they relate to such devices. As such, this research examined the use of two types of mobile devices, smartphones, and tablets, by older adults (i.e., age 65+), as well as the use of a new interface, developed for research purposes, called “PhonAge”. This study was exploratory, and utilizes frequency data and tables, in order to get a s [...]
