Perspectivas de historia y contexto cultural en la ense?anza de las ciencias: discusiones para los procesos de ense?anza y aprendizaje
Garay, Fredy Ramon Garay;
Ciência & Educa??o (Bauru) , 2011, DOI: 10.1590/S1516-73132011000100004
Abstract: this paper attempts to socialize and provide feedback on certain thoughts that arise about the relationships between: the history of science, and the cultural context of science teaching. assumed as potential view points, which have a high potential for transforming teaching and learning. these reflections take on an inclusive character that is not limited to the training of teachers but extends to training in general in science. the work is divided into: 1. history of science, 2. cultural context, 3. science education and 4. relationships between them. it does not assume that such reflections conclude such an approach, quite the contrary, it presents this as an invitation to the reader to think about teaching from a historical and cultural perspective and how this makes it possible to understand what this might mean for science education.
Elección terapéutica y transfusión sanguínea
Garay,Alain;
Medicina Legal de Costa Rica , 1995,
Abstract: when blood transfussion medicine is debated because of failures in the standard systematic blood screening system, the subject of how to manage the benefit-danger ratio in blood transfussions becomes urgent. can the patient?s right to select and optional therapeutic method when blood transfussion is not desired. through the study of jehovah 'witnesses' calims who turn to science for optional treatments, the essay insists on the implications of such a choice on public and private health policies.

Elección terapéutica y transfusión sanguínea
Alain Garay
Medicina Legal de Costa Rica , 1995,
Abstract: Cuando la medicina transfusional está en tela de juicio por el fracaso de la rutina sistemática de la sangre, es urgente plantearse la pregunta de cómo gestionar el beneficio-riesgo de la transfusión sanguínea? Puede el libre albedrío del paciente modificar la relación terapéutica? Este artículo explica el papel determinante del derecho del paciente a elegir una terapéutica de sustitución a la transfusión sanguínea. A través del estudio de las exigencias del testigo de Jehová que recurre a la ciencia para elegir un tratamiento selectivo, el artículo insiste en las incidencias del tal elección terapéutica sobre las políticas de salud pública y privada.

The maternities of high-mass stars
Guido Garay
Revista mexicana de astronomía y astrofísica , 2006,
Abstract: La comprensi on del proceso de formaci on de las estrellas masivas requiere de un conocimiento detallado de las condiciones f sicas de la nube ambiente materna ya que estas juegan un papel cr tico en la determinaci on del mecanismo de formaci on. En esta contribuci on se hace una revisi on de recientes resultados derivados a partir de observaciones de la emisi on de gas y polvo de regiones de formaci on estelar los cuales han provisto evidencia fundamental con respecto a las condiciones iniciales para la formaci on de estrellas masivas.
Vanishing cycles in complex symplectic geometry
Mauricio Garay
Mathematics , 2005,
Abstract: We study the vanishing cycles on the Milnor fibre of a holomorphic map germ with special kind of non-isolated singularities which appear in symplectic geometry. We show, under assumptions given in the text, that the Lefschetz vanishing cycles freely generate the corresponding homology group of the Milnor fibre. We study two examples of applications: involutive systems in symplectic geometry (as characteristic varieties of $\hbar$-differential equations are of this type) and ajoint orbits in Lie algebras.
Détermination finie sur un espace de Stein
Mauricio Garay
Mathematics , 2013,
Abstract: Consider the ring of holomorphic function germs in $C^n$ and denote by $M$ the maximal ideal of this ring. For any a holomorphic function germ $f$ with an isolated critical point, the finite determinacy theorem (Mather-Tougeron) asserts that there exists some $k$, such that $f+g$ can be brought back to $f$, via a holomorphic change of variables, for any $g \in M^k$. In this paper, a generalisation of this theorem for functions defined in a neighbourhood of a Stein compact subset and for an arbitrary ideal is given.
Degenerations of invariant lagrangian manifolds
Mauricio Garay
Mathematics , 2013,
Abstract: We consider a pair (H,I) where I is an involutive ideal of a Poisson algebra and H lies in I. We show that if I defines a 2n-gon singularity then, under arithmetical conditions on H, any deformation of H can "integrated" as a deformation of (H,I).

Mauricio Garay
Mathematics , 2009,
Abstract: The paper is concerned with group actions, in the context of analytic dynamical systems.
Arithmetic density
Mauricio Garay
Mathematics , 2012,
Abstract: Arithmetic class are closed subsets of the euclidean space which generalise arithmetical conditions encoutered in dynamical systems, such as diophantine conditions or Bruno type conditions. I prove density estimates for such sets using Dani-Kleinbock-Margulis techniques.
