Redefining STEAM to STEAM ∀H (STEAM for All Humanity) in Higher Education
Education SciencesThis article presents the revision of the STEAM model originally proposed by Yakman, in 2008, introducing the Human variable, as an extremely important element for the model, which was defined as STEAM ∀H, where ∀H is for all Humanity. This proposal is motivated by several factors.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).
