Learning contexts and the promotion of mathematical literacy

In today's society, we are constantly subject to a large volume of information from the most diverse domains and from the most varied sources. This requires us to mobilize skills, most often with a mathematical character, to filter, read and critically interpret this information. Furthermore, we need to be able to recognize the mathematical nature of a situation (problem) and formulate it in mathematical terms,...

LC-MS profiling and biological evaluation of methanolic extracts from local var...

The Brassica rapa spp. rapa species develops a broad, white root with thin, light green, slightly pubescent leaves. The species is consumed in Asia, Europe and North America for its nutritional benefits with low caloric value due to its low protein and lipid content, and has been used in the preparation of soups and stews. The flavor of root and leaves is slightly bitter and has been related to the degradation ...

A comparison of experimental and analytical procedures to measure passive drag ...

The aim of this study was to compare the swimming hydrodynamics assessed with experimental and analytical procedures, as well as, to learn about the relative contributions of the friction drag and pressure drag to total passive drag. Sixty young talented swimmers (30 boys and 30 girls with 13.59±0.77 and 12.61±0.07 years-old, respectively) were assessed. Passive drag was assessed with inverse dynamics of the gl...

Traditional breads prepared with Portuguese thermal mineral waters: effects on ...

Thermal waters (TW) are natural mineral waters emerging from the inside of a thermal spring, being known for their mineral composition, therapeutic application or health beneficial effects. The Northern region holds one of the main centers of TW in Portugal, located in Chaves. Although it has been used in comestic and pharmaceutical fields, in food products it has been underexploited. Thus, this study aimed to ...

Thermal stability and antioxidant activity of bioactive compounds in bread enri...

Bee pollen (BP) and bee bread (BB) are natural food sources containing a wide variety of bioactive compounds, complementing their rich nutritional composition. These bee products are being explored to empower functional foods, with the term functionality being dependent on the bioactive compounds added to the food matrix. However, there is not enough evidence of the effect of heat on these compounds during food...

Phenolic acids, cinnamic acid, and ergosterol as cosmeceutical ingredients: Sta...

The global cosmetic industry is constantly searching for new ingredients with multifunctional properties. In this context, phenolic compounds (p-hydroxybenzoic, p-coumaric, and protocatechuic acids), cinnamic acid and ergosterol were evaluated for their anti-inflammatory, anti-tyrosinase and antimicrobial activities, and thereafter microencapsulated by the atomization/coagulation technique. After characterizati...

Application of an anthocyanin-based colorant in a pastry product

The fig (Ficus carica L.) peel is an agro-industrial by-product that is not applied in any field of industry. Due to its colour, it can be considered as an important source of anthocyanins that can be used in the preparation of food colorants [1]. In the present study, an anthocyanin-based food colorant was obtained from fig peel and was applied in a food product, a doughnut icing, in order to analyse the varia...
