El primer equipo interdisciplinario de Costa Rica
Navarro Villalobos,Pablo David;
Medicina Legal de Costa Rica , 2008,
Abstract: sexual abuse is series of actitudes of a subject, which he realize in detriment of other, usually younger, for his self satisfaction. the statistics of differents countries shows that this issue is torning into epidemics amounts ant its suffocating us. prevention in revictimation is a policy established in costa rica for over a decade and for this we has had form interdisciplinary teams. in early times those temas had a lot of uncompatible disciplines soch as team is formed by only three members: the forensic doctor, the psychologist and the social worker, ehom attent to a weekly metting to analize the different conclusions of each especiallist. actually there are teams established in almost all head of province in our country with percial function well established in the legal treatment of the causes of these crimes.

Medicina Legal de Costa Rica , 2008,
Abstract: El abuso sexual es un conjunto de actitudes de un sujeto que realiza en detrimento de otro, generalmente menor, para su autosatisfacción. Las estadísticas de los diferentes países apuntan a que se está convirtiendo en una epidemia que nos está asfixiando. La prevención de la revictimización, una política establecida en el Poder Judicial de Costa Rica desde hace más de diez a os, dio como fruto la conformación de los equipos interdisciplinarios. Al inicio, estos abarcaron una serie de disciplinas tan disímiles entre sí, que comprendían tanto el derecho, como la medicina, la psicología, el trabajo social y la psiquiatría. Con el paso de los a os los equipos se fueron reduciendo hasta quedar conformados por el psicólogo, el trabajador social y el médico forense, que asiste a una reunión semanal con ellos y en donde se discuten las diferentes conclusiones de las tres disciplinas. Hoy en día son equipos establecidos prácticamente en todas las cabeceras de provincia de nuestro país con funciones periciales muy específicas en el tratamiento legal de las causas de los delitos sexuales.

A geometric approach to invariant sets for dynamical systems
David Medina,Pablo Padilla
Electronic Journal of Differential Equations , 2010,
Abstract: In this article, we present a geometric framework to study invariant sets of dynamical systems associated with differential equations. This framework is based on properties of invariant sets for an area functional. We obtain existence results for heteroclinic and periodic orbits. We also implement this approach numerically by means of the steepest descent method.
On the variety of Borels in relative position $\vec{w}$
David Joyner,Pablo Lejarraga
Mathematics , 2003,
Abstract: Let $G$ be a connected semi-simple group defined over and algebraically closed field, $T$ a fixed Cartan, $B$ a fixed Borel containing $T$, $S$ a set of simple reflections associated to the simple positive roots corresponding to $(T,B)$, and let ${\cal B}\cong G/B$ denote the Borel variety. For any $s_i\in S$, $1\leq i\leq n$, let $\bar{O}(s_1,..., s_n)= \{(B_0,..., B_{n})\in {\cal B}^{n+1} | (B_{i-1},B_{i})\in \bar{O(s_i)}, 1\leq i\leq n\}$, where $O(s)$ denotes the subvariety of pairs of Borels in ${\cal B}^2$ in relative position $s$. We show that such varieties are smooth and indicate why this result is, in one sense, best possible. Our main results assume that $k$ has characteristic 0.
Hydrogen Pick up in Zircaloy-4: Effects in the Dimensional Stability of Structural Components under Nuclear Reactor Operating Conditions  [PDF]
Pablo Vizcaíno, Cintia Paola Fagundez, Abraham David Banchik
Engineering (ENG) , 2010, DOI: 10.4236/eng.2010.28073
Abstract: In the present work, the expansion coefficient due to hydrogen incorporation was measured for the axial direction of a Zircaloy-4 cooling channel, similar to that installed in the Atucha I PHWR, Argentina, trying to simulate the nuclear power reactor operating conditions. As a first step, the solubility curve of hydrogen in Zircloy-4 was determined by two techniques: differential scanning calorimetry and differential dilatometry. The comparison with classical literature curves showed a good agreement with them, although the calorimetric technique proved to be more accurate for these determinations. Dilatometry was able to detect the end of hydride dissolution from concentrations around 60 wppm-H up to 650 wppm-H, where the eutectoid reaction: α + δ→α + β takes place (at 550oC). We assume that this ability is a good indicator of the aptitude of the technique to measure dimensional changes in the given hydrogen concentration range. Then, the expansion of Zircaloy-4 homogeneously hydrided samples was measured at 300oC, the typical operating temperature of a nuclear power reactor, obtaining a relative expansion of 2.21 * 10-4% per wppm-H. Considering the relative expansion observed for Zircaloy-4 at room temperature due to hydriding, starting from a hydrogen free sample, the total relative expansion rate is calculated to be 5.21 * 10-4% per wppm-H.
Desafección cívica, polarización ideológica y calidad de la democracia: una introducción al Anuario Político de América Latina
Altman,David; Luna,Juan Pablo;
Revista de ciencia política (Santiago) , 2007, DOI: 10.4067/S0718-090X2007000100001
Abstract: the year 2006 was marked by extraordinary electoral activity all over the continent. this year has also shown a higher than normal level of conflict between countries, amounting in some cases to serious diplomatic friction. in addition, there were evident domestic problems touching almost every country: enduring deficits of human development despite an economic expansion, the systematic exclusion of important social groups from the political arena, and an increasing level of political disaffection among the population as a whole. some countries were paralyzed by conflicts and stalemates between the branches of government, and in a broader sense, serious shortcomings have been observed in respect to "democratic governability". although democracy is firmly in place in most of the continent and elections are the main vehicle for selecting governments, we are now facing problems to which, years ago and for understandable reasons, political scientists did not give sufficient attention. the political reality of the region has become so fluid and the new challenges are so varied and significant, that an annual comparative chronicle on the political processes lived by each country constitutes, to our understanding, a fundamental and necessary tool for research. this article is meant to offer an introduction to this political data yearbook of latin america
Desafección cívica, polarización ideológica y calidad de la democracia: una introducción al Anuario Político de América Latina
David Altman,Juan Pablo Luna
Revista de Ciencia Política , 2007,
Abstract: El a o 2006 América Latina estuvo dominada por una inusual actividad electoral a lo largo y ancho del continente. A nivel de relaciones internacionales, este a o se caracterizó por mostrar un nivel infrecuente de conflictividad entre los países, llegando inclusive a manifestarse en roces diplomáticos serios. Al interior de cada país, también resultaron evidentes problemas transversales: déficits persistentes de desarrollo humano a contramano de la expansión económica, la exclusión casi sistemática de importantes grupos sociales del juego político, la persistencia de discriminación social y política por razones de género y/o étnicas, y la presencia de un creciente nivel de desafección política. En algunos países, además, han existido roces entre los ejecutivos y los legislativos y, en un sentido más amplio, se han observado múltiples deficiencias a nivel de "gobernabilidad democrática". Si bien la democracia ha logrado instalarse en la gran mayoría del continente y las elecciones son el principal vehículo de selección de gobiernos, hoy resultan evidentes problemas a los que en un momento de transición, y por razones entendibles, la disciplina no otorgó suficiente importancia. La realidad política de la región se ha vuelto tan dinámica y "fluida" y los nuevos desafíos de nuestras democracias son actualmente tan variados y significativos, que una crónica comparativa anual sobre los procesos políticos vividos por cada país constituye, a nuestro entender, una herramienta de investigación tan fundamental como necesaria. Este trabajo ofrece una introducción a este anuario The year 2006 was marked by extraordinary electoral activity all over the continent.

Quantitative $(p,q)$ theorems in combinatorial geometry
David Rolnick,Pablo Soberón
Mathematics , 2015,
Abstract: We show quantitative versions of classic results in discrete geometry, where the size of a convex set is determined by some non-negative function. We give versions of this kind for the selection theorem of B\'ar\'any, the existence of weak epsilon-nets for convex sets and the $(p,q)$ theorem of Alon and Kleitman. These methods can be applied to functions such as the volume, surface area or number of points of a discrete set. We also give general quantitative versions of the colorful Helly theorem for continuous functions.
A review of learning vector quantization classifiers
David Nova,Pablo A. Estevez
Computer Science , 2015, DOI: 10.1007/s00521-013-1535-3
Abstract: In this work we present a review of the state of the art of Learning Vector Quantization (LVQ) classifiers. A taxonomy is proposed which integrates the most relevant LVQ approaches to date. The main concepts associated with modern LVQ approaches are defined. A comparison is made among eleven LVQ classifiers using one real-world and two artificial datasets.
Chiral β-Amino Alcohols as Ligands for the Ruthenium-Catalyzed Asymmetric Transfer Hydrogenation of N-Phosphinyl Ketimines
óscar Pablo,David Guijarro,Miguel Yus
Applied Sciences , 2012, DOI: 10.3390/app2010001
Abstract: Some chiral β-amino alcohols have been evaluated as potential ligands for the ruthenium-catalyzed asymmetric transfer hydrogenation (ATH) of N-phosphinyl ketimines in isopropyl alcohol. The ruthenium complex prepared from [RuCl 2( p-cymene)] 2 and (1 S,2 R)-1-amino-2-indanol has shown to be an efficient catalyst for the ATH of several N-(diphenylphosphinyl)imines, affording the reduction products in very good isolated yields and enantiomeric excesses up to 82%. The inherent rigidity of the indane ring system present in the ligand seems to be very important to achieve good enantioselectivities.
