This study investigates the relationship between entropy and societal dynamics, with a particular focus on the origins and implications of war. By using entropy as a measure of uncertainty and inequality, the research examines societal stability through patterns of stratification and wealth distribution. Employing simplified models of various wealth distributions, the study explores their effects on social stratification and the potential for conflict. Drawing on historical and contemporary examples, it delves into [...]

Precision agriculture depends on the automation and mechanization of agricultural equipment and vehicles in a variety of terrains, which increases productivity and sustainability. This review presents a comparative analysis of significant simulation software used in designing and developing automated agricultural systems, emphasizing their methodologies and significance in advancing farm technology. Artificial intelligence (AI) and machine learning (ML) methods are modeled, optimized, and integrated using key techn [...]

The main aim of this work is to analyze the impact of the National Minimum Wage (NMW) on wealth redistribution in Spain during the 2001-2021 period. This research addresses a fundamental question: Does increasing the minimum wage effectively reduce income inequality and contribute to a more equitable wealth distribution without negatively impacting overall economic growth and employment? Using a complete statistical census provided by the Spanish Tax Administration Agency, this study examines how the increase in th [...]

Carbon capture and storage (CCS) technology mitigates greenhouse gas (GHG) emissions. However, comprehensive studies assessing the sustainability of coal-based power generation (CBPG) with CCS remain limited. This study focuses on developing comparative sustainability indicators across the entire life cycle of CBPG integrated with CCS technology. Sixty-six pathways were analyzed after establishing five sustainability indicators for each. These indicators were standardized per megawatt-hour (MWh) of energy, encompas [...]

The biochemical properties of metal complexes containing benzo hydrazide Schiff base have been reported by numerous researchers worldwide in various ways. In this work, the evaluation of biochemical roles of the metal complexes with benzo hydrazide Schiff base activity as anti-gram positive and gram-negative bacteria, as well as antifungal agents, were observed. The use of various techniques, including the induced fit docking methodology, the density functional theory method, and pharmacokinetics investigations wit [...]

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]

This study descriptively investigates the food acceptance patterns and dietary profiles of neurotypical infants, children, and adolescents with Feeding Difficulties (FD) at a Brazilian pediatric reference center. It further examines whether a broader food repertoire translates into improved nutritional quality. The research, an observational, analytical cross-sectional study, analyzed data from 237 patients aged 10 to 204 months with FD. Findings revealed a discrepancy between family perceptions and professional as [...]

To study the relationship of dietary score versus age at death (AD) in an extinct cohort at 61 years of follow-up, based on an “inverse” procedure. Data from the Italian Rural Areas (IRA) of the Seven Countries Study of Cardiovascular Diseases, made up of 1712 middle-aged men followed for 61 years, were used. The “direct” approach means applying a dietary score to each subject of a cohort and, by means of a model, estimating the probabilities of events for different dietary score levels. The “inverse” approach, ins [...]

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 [...]
