Translation and Reception of The Wealth of Nations by Spanish and Latin American Authors during Eighteenth and Nineteenth Centuries  [PDF]
Paz Molero Hernández
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.35008
Abstract: The objective of this paper is not the complete work, but namely to analyze the reasons for which in Spain and Latin America The Wealth of Nations, was censored in the eighteenth and nineteenth centuries and to analyze in turn whether the reasons for this censorship correspond to the ideas that Adam Smith effectively defended. It is not intended to judge the intention of any of the parties involved in this process but to understand the context in which they occurred, and to judge whether people in Spanish-speaking countries during those centuries knew what Adam Smith actually wanted to express.
The Development of the Renewable Energy Technologies in Spain  [PDF]
Félix Hernández, Miguel Hernández-Campos
Smart Grid and Renewable Energy (SGRE) , 2011, DOI: 10.4236/sgre.2011.22013
Abstract: This article examines the development of the four main renewable energy technologies (RET) in Spain in the latest years: biomass, small hydro (SH), solar photovoltaic (solar PV) and wind. It has been studied the variation of the work-ing time per MW installed available from the on line data base of Spanish National Commission on Energy (SNCE), in the national context and in each of the Autonomic Communities (AACC). We have also obtained the marginal cost curve of the global RE. The main conclusions of the study are that Spain is effective meeting the RE generation target but not efficient in costs and in short term it is not any RETs that can achieve competitive price comparing to the elec-trical market.
Análisis exploratorio espacial de los accidentes de tránsito en Ciudad Juárez, México
Hernández Hernández,Vladimir;
Revista Panamericana de Salud Pública , 2012, DOI: 10.1590/S1020-49892012000500007
Abstract: objective: prepare a tool for the exploratory study of road accidents in ciudad juarez, chihuahua, mexico, that exclusively applies the spatial geographical variable (location). methods: observational and cross-sectional study that uses a geographic information system to explore the spatial nature of 13 305 road accidents recorded during 2008 and 2009 in ciudad juarez. indicators were constructed that approximated the transit flow and included two variables: indices of the level of urbanization and population density. results: the value of the global spatial autocorrelation was positive, indicating the presence of groupings that were identified through the spatial association indicators. there are road risk clusters located in areas with a high level of urbanization, low population density, and a high transit flow level. conclusions: the exploratory analysis of spatial data is a phase that precedes the use of multivariate techniques with a broader scope. the application of exploratory analysis techniques in itself makes it possible to standardize spatial groupings, identify global autocorrelation, and indicate the direction of the variables under study.
Polineuropatía desmielinizante inflamatoria crónica: Aspectos clínicos y electrofisiológicos
Hernández Hernández,Aymeé;
Acta Neurológica Colombiana , 2012,
Abstract: chronic demyelinating inflammatory polineuropathy (cidp) is a kind of peripheral neuropathy predominantly motor of autoimmune cause and chronic course. its start insidiously, it can affect both sex, more frequent male. it can appear in any time of life more frequent in second decade. it is very important differentiate of other illness because it has good response to inmunosupresor agents. diagnosis is support ed in four aspects: clinical, electrodiagnostic studies, brain spinal fluid study and anatomo-pathologycal issues. diagnosis is polemic and controversial, with different diagnosis criteria, because they not include atypical variants. we have to review ed this topic, and show clinical, electrophysiological, fisiopathological and pathological aspects and also our experience in the study of cidp patients throw twelve years in la habana, cuba.
Contribución de la electrofisiología al diagnóstico diferencial entre el síndrome de Guillain Barré y la polineurorradiculopatía desmielinizante inflamatoria crónica
Hernández Hernández,Aymeé;
Revista Cubana de Investigaciones Biom??dicas , 2008,
Abstract: introduction: the guillain barré syndrome (gbs) and the chronic inflammatory demyelinizating polyneuroradiculopathy (cidp) share similarities. one differ from the other in their beginning, course, evolution, prognosis and response to the treatment, but there are difficulties for their differentiation in the clinical practice. objectives: to compare the alteration patterns of the electrophysiological studies in patients with gbs and cidp to look for differences between them in order to have a tool contributing to the differential diagnosis of both diseases. methods: 18 patients with gbs and 27 with cidp, who underwent conduction study and wave f were studied. results: significant differences existed among the evaluated variables in these studies in both groups of illnesses. it was demonstrated that in both groups there exists affectation of the motor fibers, and that it is higher from the sensitive point of view in the cidp. the electrophysiological affectation pattern was different in both illnesses. conclusions: gbs can be differentiated from the cidp through the nervous conduction study and the f. wave
Evolución electrofisiológica de un grupo de pacientes con Polineuropatía Desmielinizante Inflamatoria Crónica primaria y secundaria
Hernández Hernández,Aymeé;
Revista Cubana de Investigaciones Biom??dicas , 2008,
Abstract: introduction: chronic inflammatory demyelinating polyneuropathy (cidp) has different forms of presentation; the idiopathic form and that related to concurrent diseases. the neurophysiological studies play a fundamental role in the diagnosis. objetives: we proposed to compare the electrophysiological evolution by analyzing the variables evaluated through the nervous conduction study of a group of patients with primary and secondary cidp at two evolutive moments of the disease. methods: 9 patients with primary cidp and 6 with cidp related to diabetes mellitus, multiple sclerosis and adenocarcinoma were studied. a nervous conduction study of the nerves of the extremities was performed at the moment of the diagnosis of the disease and a year after treatment. the electrophysiological variables were compared in both moments by using nonparametric statistical techniques. results: the patients with primary cidp showed evolutive improvement of the electrophysiological variables with normalization of the study in two cases. patients with secondary cidp got worse. conclusions: it was concluded that patients with secondary cidp showed a torpid electrophysiological evolution with reserved prognosis.
Del método científico al clínico: Consideraciones teóricas
Hernández Hernández,Roberto;
Revista Cubana de Medicina General Integral , 2002,
Abstract: el método científico es un método general, constituido por varias etapas necesarias en el desarrollo de toda investigación científica. es la forma de abordar la realidad y estudiar los fenómenos de la naturaleza, la realidad y el pensamiento para descubrir su esencia y sus interrelaciones. el método clínico es la aplicación particular del método científico, y en las condiciones económicas actuales resulta vital en aplicación por las ventajas que reporta desde ese punto de vista, así como también por el bienestar del paciente.
Escultura zoomorfa de Monterrubio de la serena (Badajoz). Una aproximación a su interpretación socio-cultural y simbólica
Hernández Hernández, Francisca
Trabajos de Prehistoria , 1992,
Abstract: We present a study of a new stone sculpture of a ram, found in Monterrubio de la Serena (Badajoz). If from a formal point of view it must be related to Andalusian Iberian sculpture, its symbolic evaluation lead us to compare it with other plastic representations found in several cultural contexts. These are frequently associated with burial and religious rites, where they can symbolize the passage from death to Iife, or with some scenes of sacrifices offered to the deity. Such rites came from the Eastern Mediterranean and they spread out around the Iberian Peninsula during the first millennium B.C. Presentamos el estudio de una nueva escultura de carnero en piedra, hallada en Monterrubio de la Serena (Badajoz). Si desde el punto de vista formal hay que relacionarla con la escultura Ibérica andaluza, su valoración simbólica nos lleva a compararla con otras representaciones plásticas encontradas en diversos contextos culturales. Estos se asocian, frecuentemente, a ritos funerarios y religiosos, pudiendo simbolizar el tránsito del ámbito de la muerte a la vida o escenas de sacrificios ofrecidos a la divinidad. Dichos ritos tienen su origen en el Mediterráneo Oriental y se extenderán a lo largo del I Milenio en la Península Ibérica.

Revista Cubana de Investigaciones Biom??dicas , 2008,
Abstract: Introducción: La Polineuropatía Desmielinizante Inflamatoria Crónica (CIDP) es tiene diferentes formas clínicas de presentación; la forma idiopática y la relacionada con enfermedades concurrentes. Los estudios neurofisiológicos juegan un papel determinante en el diagnóstico. Objetivos: Nos propusimos comparar la evolución electrofisiológica a través del análisis de las variables evaluadas a través del estudio de conducción nerviosa de un grupo de pacientes con CIDP primaria y secundaria en dos momentos evolutivos de la enfermedad. Metodos: Se estudiaron 9 pacientes con CIDP primaria 6 con CIDP relacionada con diabetes mellitus, esclerosis múltiple y adenocarcinoma. Se les realizó estudio de conducción nerviosa de los nervios de extremidades, en el momento del diagnóstico de la enfermedad y al a o de tratamiento. Se compararon las variables electrofisiológicas en ambos momentos utilizando técnicas de estadística no paramétricas. Resultados: Los pacientes con CIDP primaria mostraron mejoría evolutiva de las variables electrofisiológicas, con normalización del estudio en dos casos. Mientras que en los pacientes con CIDP secundaria existió empeoramiento. Conclusiones: Concluimos que los pacientes con CIDP secundaria muestran una evolución electrofisiológica tórpida con pronóstico reservado.
