essays represented the most stimulating part of the book to this reviewer. I was particularly interested in the papers by Simpson and Tait on Aldosterone and the one by Harris and Fortier on the regulation of the release of ACTH. All of the essays are useful, but their contents have appeared in previous reviews elsewhere, often by the same authors; indeed, Moore's paper on "Bodily changes in Su...

El propósito de este trabajo es enfatizar la importancia del uso multimedios para mejora proceso enseñanza y aprendizaje matemáticas. Para esto fue necesario utilizar el tipo investigación descriptiva, aplicando métodos prácticos técnicas recolección datos, en que se utilizan herramientas como observación, entrevista encuesta. La base teórica sustenta los antecedentes establecidos por Areces, (...

Given an edge-coloured graph, we say that a subgraph is rainbow if all of its edges have different colours. Let $\operatorname{ex}(n,H,$rainbow-$F)$ denote the maximal number copies $H$ properly graph on $n$ vertices can contain it has no isomorphic to $F$. We determine order magnitude $\operatorname{ex}(n,C_s,$rainbow-$C_t)$ for $s,t$ with $s\not =3$. In particular, answer question Gerbner, M\...

Magnetars have been considered as progenitors of magnetar giant flares (MGFs) and fast radio bursts (FRBs). We present detailed studies on afterglow emissions caused by that occur in their wind nebulae surrounding baryonic ejecta. In particular, following the bursts-in-bubble model proposed Murase, Kashiyama \& M\'esz\'aros, we analytically numerically calculate spectra light curves such emissi...
