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 [...]

Cottage cheese is a promising matrix for delivering probiotic microorganisms due to its buffering capacity, high moisture content, and consumer acceptance. In this study, a probiotic cottage cheese incorporating Lactobacillus acidophilus LA-5 was developed and evaluated against a control formulation and commercial products. Physicochemical properties, probiotic viability, acidification kinetics, and sensory acceptance were assessed during refrigerated storage. The formulation consistently maintains viable probiotic [...]

The unbalanced nutrient density and low microbiological quality of many complementary foods are still the primary causes of infant malnutrition in poorer countries. In this study, complementary food was produced using blends of grain amaranth, African yam bean, and carrot flour. The resultant complementary food was analysed for proximate, mineral, antinutrients, antioxidant compositions, vitamin C, beta-carotene, microbial properties, and sensory evaluations. Principal component analysis was also used to assess nut [...]

Berberine is an alkaloid chemical found in plants, including Berberidaceae, Coptis rhizomes, and Hydrastis canadensis. Berberine has been shown to improve insulin sensitivity, promote adipocyte loss, and is associated with higher levels of skeletal muscle protein synthesis. The purpose of this study was to examine berberine’s dose-dependent effects on C2C12 myoblast proliferation and 3T3L1 adipocyte differentiation. Cells were grown out over 3 weeks, and once confluent at 90%, they were treated with berberine to ex [...]
