Serum steroid and thyroid hormone concentrations in healthy domestic male and female alpacas.

Alpacas are high quality fiber producing animals, kept for production purpose and as pets. Endocrine imbalances from adrenal glands, gonads, or thyroid gland may result in coat abnormalities in domestic animals and affect reproduction. Contrary to many domesticated animals, information on hormone concentrations in alpacas is scarce.

Results and analysis of an intercomparisons study for individual monitoring services of Latin American and Caribbean regions.

The aim of this paper is to present the results obtained by the Latin-American and Caribbean personal dosimetry services that participated, with the support of IAEA, in the 2020-Eurados whole-body dosemeter intercomparison for photon radiation. All participant services in this study use thermoluminescent dosimetry (TLD) systems except one that uses optically stimulated luminescence (OSL) dosemeters. Data analysis shows that 93.

Ethical enactivism for smart and inclusive STEAM learning design.

Current global challenges of the 21st century promote STEAM (science, technology, engineering, arts and mathematics) education and digitalization as a means for humans to be the central actors in the construction of a sustainable society that favors a sense of worth and global wellbeing. In this scenario, new educational technology tools and immersive learning affordances (possibilities), offer unprecedented potential for the design of smart and dynamic learning systems and contexts that can enhance learning processes across varied audiences and educational settings. However, current STEAM education practice lacks attention to equipping all citizens with the necessary skills to use digital technologies in an ethical, critical and creative way.

Copper oxide wire particles effective against gastrointestinal nematodes in adult alpacas during a randomized clinical trial.

Objective: To determine whether copper oxide wire particles (COWP) administered as an oral bolus effectively decrease fecal gastrointestinal nematode (GIN) egg counts in adult alpacas.

Animals: 57 adult alpacas.

Procedures: A double-blind clinical trial was performed during the months of April through August 2019.
