The Mediterranean Diet vs. 21st Century Lifestyle: A Review

The Mediterranean diet (MD) is widely recognized for its health benefits and its association with reduced incidence of noncommunicable diseases. However, modern lifestyles, characterized by increased consumption of ready-to-eat (RTE) foods and limited time for meal preparation, p...

Physicochemical Characterization of Acorn Flour (Quercus spp.) for Its Potential Application as a Natural Pharmaceutical Excipient

Background/Objectives: Acorn flour has attracted attention as a potential starch-based excipient, yet comprehensive data on its powder properties and compaction behaviour remain limited. This study aimed to characterise the physicochemical properties and tableting performance of...

Making migration-embedded learning visible for inclusive entrepreneurship education

Entrepreneurial education for migrant populations often prioritizes technical-business content and overlooks the experiential, relational and contextual learning embedded in migratory trajectories. This article presents the development and initial content assessment of MELT, Migr...

Structural Performance of Crumb Rubber-Modified Asphalt Under Service Conditions: A Mechanistic and Machine-Learning Assessment

Crumb rubber (CR) modification offers a sustainable approach to improving asphalt performance while promoting the beneficial reuse of end-of-life tyres. This study evaluates the structural performance of CR-modified hot mix asphalt (HMA) under service conditions through an integr...

Lightweight Mortars Incorporating LECA, Perlite, and Crumb Rubber: Influence of SBR–PPF Modification on Material Performance

Developing lightweight cementitious materials incorporating recycled constituents while maintaining appropriate functional performance requires a balance between density, mechanical resistance, durability-related properties, and thermal efficiency. This study comparatively evalua...

Polysaccharide Reengineering: Strategic Modifications and Biofunctional Outcomes of Natural Polysaccharides

Natural polysaccharides have attracted considerable interest in pharmaceutical and biomedical applications. However, native polysaccharides often possess limitations, like poor solubility, inadequate mechanical strength, limited stability, and insufficient control over their func...

POLIS V13: A Universal Tensional Conservation Theory – Unification of Matter, Energy, Information, Gravity, Light, Life, Consciousness and Cosmology

POLIS V13 is the complete formulation of the tensional conservation framework, generalising V12 while preserving all its empirical validations. The theory replaces fixed physical analogies (solid, liquid, gaseous) with neutral tensional layers identified solely by their normalise...
