Thirty years after the cuban hemorrhagic dengue epidemic of 1981
Guzmán,María G.;
MEDICC Review , 2012, DOI: 10.1590/S1555-79602012000200012
Abstract: in 1981, cuba reported the first hemorrhagic dengue epidemic in the americas, with 344,203 cases, including 10,312 severe and very severe cases, resulting in 158 deaths. in the 30 years following the epidemic, surveillance, control and research have kept cuba dengue free; although isolated, interrupted epidemics and transmissions have been reported. in this article, we summarize issues of interest regarding the 1981 epidemic, as well as laboratory surveillance data and various related research results.

EFECTOS DE LA DISPERSIóN RETRIBUTIVA EN LOS RESULTADOS DE LAS EMPRESAS COTIZADAS ESPA OLAS: EVIDENCIA SOBRE EL MODELO DEL TORNEO
Sánchez Marín, G.
Investigaciones Europeas de Direccion y Economia de la Empresa , 2010,
Abstract: La literatura ha puesto en cuestión si realmente las grandes diferencias retributivas entre directivos están vinculadas con mejores resultados de la organización. En este trabajo, sobre la base de los argumentos de la teoría del torneo, se ha tratado de aportar nuevas evidencias en esta línea, utilizando para ello datos de las 120 empresas espa olas que cotizan en Bolsa. Los resultados obtenidos, considerando la forma convexa en las relaciones dispersión-resultados de Brown et al. (2003) y las características del trabajo directivo –alto nivel jerárquico, interdependencia moderada y alta incertidumbre-, indican que existe una relación positiva, aunque moderada por ciertas variables, entre dispersión retributiva y resultados de la empresa.
Air Pollution in the Gulf of Mexico  [PDF]
Manuel Muriel-García, Rosa María Cerón-Bretón, Julia G. Cerón-Bretón
Open Journal of Ecology (OJE) , 2016, DOI: 10.4236/oje.2016.61004
Abstract: An integral analysis of Air Pollution in the Gulf of Mexico was made considering pollutants emissions assessment and diagnosis; air pollution monitoring; and modeling of air pollution dispersion. Combustion sources considered in this work were: thermoelectric power plants and open flares; and pollutants considered were sulfur dioxide, nitrogen dioxides, particulate matter (PM10 and PM2.5), Total suspended particles (TSP) and carbon monoxide (CO). This study made evident a lack of more recent information and a homogenization in emissions factors in order to know the conditions of air pollution in the Gulf of Mexico in a more reliable way.
A Comparative Study on the Structural and Vibrational Properties of Two Potential Antimicrobial and Anticancer Cyanopyridine Derivatives  [PDF]
María J. Márquez, María B. Márquez, Pablo G. Cataldo, Silvia A. Brandán
Open Journal of Synthesis Theory and Applications (OJSTA) , 2015, DOI: 10.4236/ojsta.2015.41001
Abstract: 2-Hydroxy-4,6-dimethylpyridine-3-carbonitrile and 2-chloro-4,6-dimethylpyridine-3-carbonitrile compounds have been studied from a theoretical point of view in order to know their structural and vibrational properties in gas and aqueous solution phases by means of Density Functional Theory (DFT) calculations. The stable structures in both media were optimized by using the hybrid B3LYP/6-31G* method and the solvent effects in aqueous solution were studied by using the integral equation formalism of the polarizable continuum model (IEFPCM) employing the selfconsistent reaction field (SCRF) method. Detailed vibrational analyses for both compounds in the two phases were performed combining the DFT calculations with Pulay’s Scaled Quantum Mechanics Force Field (SQMFF) methodology. The different interactions for both compounds were analyzed by means of the bond orders, atomic charges, solvation energies, dipole moments, molecular electrostatic potentials and force constants parameters. The nature of the interactions was studied by using different descriptors.
De las nociones de paradigma, episteme y obstáculo epistemológico
Gómez Marín,Raúl;
Co-herencia , 2010,
Abstract: what relationships can outline between the notions of paradigm, episteme and epistemological obstacle? this text highlights, on the one hand, the epistemological importance of such relationships, and the other hand, tries to suggest how have recourse such notions in the process of design of a research.
Las implicaciones jurídicas, sociales y económicas de los cinco gremios mayores de Madrid como institución mercantil y financiera en la Espa?a del siglo XVIII
Gómez Rojo,María Encarnación;
Revista de estudios histórico-jurídicos , 2008, DOI: 10.4067/S0716-54552008000100007
Abstract: beginning with the establishment of the court in madrid and the role of middle class in the old regime, the origin of the association of the five greatest unions is studied, as well as their regulations and their functions as a mercantile institution -when changing into a society privileged by shares-, and as a pre-capitalist financing institution and antecedent of the modern banking.
La Ense?anza del Derecho Histórico Penal en Francia Ante el Espacio Europeo de Educación Superior
Gómez Rojo,María Encarnación;
Revista de estudios histórico-jurídicos , 2007, DOI: 10.4067/S0716-54552007000100014
Abstract: this paper is based on the historical-legal subjects in criminal matter taught nowadays in some french universities fol-lowing the last guidelines in the matter that try to adapt the teachings to the european system of higher education.
La Historia de las Universidades como objeto de la Historia del Derecho en su orientación institucional
Gómez Rojo,María Encarnación;
Revista de estudios histórico-jurídicos , 2006, DOI: 10.4067/S0716-54552006000100017
Abstract: this is a brief exposition focused on the object of the history of law from an institutional perspective. this exposition attempts to combine the study of universities through their historic, juridical, and institutional characterization in the discipline with reference to the main doctrinal positions
