The increasing demand for renewable energy sources has intensified the adoption of photovoltaic systems. This study proposes predictive models for solar power generation that operate without dependence on on-site meteorological stations. The proposed approach integrates generation data from geographically distributed plants and accounts for the distance to meteorological stations when constructing climatic variables. Two machine learning techniques, Random Forest (RF) and Long Short-Term Memory (LSTM) networks, wer [...]

Food-system by-products (FSBP), including agricultural by-products, agro-industrial co-products, and food-processing residues, represent an underused source of nutrients and plant secondary compounds with significant potential in ruminant feeding systems. This review synthesized 96 peer-reviewed studies published between 2000 and 2025 on phytochemically rich FSBP in ruminant diets, focusing on composition, rumen fermentation, animal health and performance, product quality, and environmental outcomes. Across the stu [...]

The article reveals the variability of the genome of cattle of the local small-numbered domestic Brown Carpathian breed using cytogenetic and molecular genetic polylocus markers, and justifies the need to integrate local breeds into the modern system of agricultural production in accordance with FAO requirements. The work aimed to study the genetic uniqueness of cows of the brown Carpathian breed using cytogenetic and molecular genetic markers. The karyotype of the animals corresponded to the species norm and was 2 [...]

In 2025, college students are reportedly more anxious and strained than any previous generation of young people, while they are also the first to have grown up entirely immersed in social media. This research explores social media use patterns and their relationship with academic, emotional, health-related and social well-being among college students. A total of 111 college students from an East Coast university self-selected to complete a one-time assessment anonymously through Qualtrics. A mixed-methods, explorat [...]

Central post-stroke pain (CPSP) is a frequently underrecognized complication that contributes to long-term disability among stroke survivors. This study aimed to determine the frequency of CPSP and to describe its clinical characteristics and associated factors among stroke patients treated at Arifin Achmad General Hospital. A cross-sectional design was employed and included adult stroke patients with diagnoses confirmed by neuroimaging. CPSP was diagnosed based on the clinical criteria proposed by Klit et al., and [...]

Elder abuse is a global public health issue, with consequences on individual health, increased burden on healthcare systems, and high social costs. The study aimed to estimate the prevalence of family violence among older adults in Brazil and analyze its association with disability, comorbidities, functional limitation, and sociodemographic characteristics. Cross-sectional study using data from the 2019 National Health Survey (PNS 2019), including older adults aged 60 years or older. Bivariate and multiple logistic [...]

Electrical submersible pumps (ESPs) are an efficient and reliable artificial lift method for lifting large volumes of fluids from wellbores at flexible rates. Despite their advantages, including high flow rates and real-time downhole telemetry, ESPs are prone to frequent and unforeseen failures under harsh reservoir conditions, resulting in costly production delays and interventions. This paper presents an integrated evaluation of ESP failure mechanisms based on an analysis of run and pull reports, dismantle inspec [...]

Non-invasive prenatal testing (NIPT) is now standard in prenatal care in many countries, even though it was introduced only about 15 years ago. Due to its rapid adoption into decades-old prenatal care plans, gynecologists, obstetricians, and the general public still struggle to understand the possibilities, benefits, and limitations of NIPT. The biggest challenge facing NIPT is that comprehensive training for healthcare professionals and independent, unbiased information for pregnant women and their families about [...]

Genetically conditioned variation in pollen has been demonstrated to have a substantial influence on reproductive mechanisms and population dynamics. The present study evaluated the genetic variability of 28 pollen samples of Corylus avellana L. using iPBS (Inter Primer Binding Sites Polymorphism) markers 1882 and 2152. The collection of biological material was undertaken at various locations across five European countries, with the objective of capturing a broad spectrum of environmental conditions. The genetic re [...]

Transplanting islets into the subcutaneous (SC) space rather than the portal vein is advantageous because this site is easier and safer to use. However, transplantation of islets directly or within planar devices has been unsuccessful in humans, mainly because of the low oxygen torr in the SC space. Since human islets are very different from mouse islets, the use of human islets in animal experiments to study SC islet transplantation may help to alleviate the roadblocks of this approach in humans. This is the first [...]
