Descubrimiento del hipotiroidismo
Revista Colombiana de Endocrinología, Diabetes & Metabolismo, 2017 Fragmento. La relación entre la glándula tiroides, cretinismo, mixedema del adulto y caquexia estrumipriva solo fue definida hacia finales del siglo XIX. El concepto de hipotiroidismo, que hoy nos parece obvio y sencillo, no existía. Habría que esperar a que —a finales del siglo XX— se descubriera el radioinmunoanálisis, se midieran las hormonas ...

International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.ABSTRACT A general bipenalty formulation with a parameter selection criterion is proposed for explicit contact‐impact finite element analysis. In order to model the contact phenomenon using penalties, it is necessary to introduce an artificial contact stiffness that can increase the maximum natural frequency of the system.

PLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 87-104, January 2025.Addressing the burning environmental crisis, we explore how the ‘extreme sport’ of paramotoring can enhance and accelerate scientific exploration with minimal environmental impact compared to off‐road vehicles. Our study demonstrates the scientific potential of paramotoring to access fragile desert ecosystems and investigate unrecorded habitats and ...
