Mixture–Process Design and Multiresponse Optimization of Starch–Gelatin Films Containing Nopal-Opuntia spp. Mucilage: Mechanical Properties and Apparent Mass Loss

The performance of biopolymer films depends on both composition and formation conditions. This study evaluated films containing constant amounts of Nopal-Opuntia spp. mucilage, glycerol, and vinegar using a 16-run mixture–process design with four starch–gelatin ratios and post-dr...

Antitumor-Relevant Evaluation of Liquid and Microencapsulated Lepidium meyenii and Bactris gasipaes Extracts Reveals Species- and Formulation-Dependent Activity

Lepidium meyenii and Bactris gasipaes are traditionally consumed plant foods with documented antioxidant and inflammation-related activities and emerging evidence of cancer-related biological effects. Accordingly, we compared the antitumor-relevant activity of these chemically di...

From learning to action: transformative pedagogies driving SDG-oriented entrepreneurship in higher education

Purpose This study aims to analyze how project-based learning (PBL) in higher education entrepreneurship courses contributes to the development of sustainable entrepreneurial competencies and to students’ social and environmental commitment, highlighting its relevance to the achi...

Real-World Emission Factors for Andean Light-Duty Vehicles Based on a PSVm10-Validated Driving Cycle Across 0–4000 m Altitude

Emission inventories for high-altitude Andean cities rely on sea-level certification cycles that misrepresent real-world combustion conditions. This study derives altitude-resolved emission factors (EFs) for light-duty gasoline vehicles across 0–4000 m a.s.l. in Ecuador using the...
