Abstract: Sheet metal forming processes represent an important group of manufacturing processes for dissimilar applications. The development of numerical simulation methods has created new possibilities in important industrial aspects with regard to optimization and integration CAPP system in sheet metal drawing processes. The result of the processes depends on a large number of parameters and their interdependence hence, knowledge and experience of the designer are critical. The present work deals with the elements to be considered in the integral design, planning and optimization sheet metal drawing processes under a set of criteria and as such the possibilities that this task offers in the decision making, preparation along with the analysis and synthesis of engineering systems. In addition a methodology for integration design and process planning of sheet metal forming process analysis is summarized. Los procesos de conformación de chapas metálicas representan un grupo significativo de procesos de manufactura de piezas para diferentes aplicaciones. El desarrollo de los métodos de simulación ha creado nuevas posibilidades en importantes aspectos industriales relacionados con la optimización de los procesos de embutición y la integración en sistemas CAPP (planeación de procesos asistida por la computación). En el presente trabajo se resumen las tendencias a considerar en la integración del dise o, la planificación y la optimización en los procesos de embutido de chapas, así como las posibilidades que ofrece esta tarea para el análisis y síntesis de sistemas de ingeniería y en la preparación y toma de decisiones bajo criterios múltiples.

Revista Cubana de Enfermer?-a , 2011,
Abstract: La Gestión del Cuidado es una acción propia del profesional de enfermería que realiza con otras personas para promover su salud, prevenir, diagnosticar, tratar y rehabilitar las enfermedades que puedan padecer, y para ello es necesario aplicar la teoría de la enfermería transcultural, por lo que realizamos un estudio descriptivo y transversal con el objetivo de determinar si nuestros profesionales realizan la gestión de cuidados de enfermería desde una perspectiva transcultural. El estudio se realizó de enero a marzo del a o 2008 con 280 profesionales de enfermería de la atención primaria y secundaria de salud (25% del universo) seleccionados por muestreo simple aleatorio. Las variables necesarias se recogieron a través de una encuesta y con criterio de especialistas. Encontramos insuficientes conocimientos sobre el tema, sobre todo en los de menos edad y con menos a os de graduados; los de la atención secundaria presentan mejores resultados; de los 26 que dijeron haber recibido cursos u otro tipo de preparación sobre transculturación, sólo 16 mantienen esos conocimientos.

Revista Cubana de Salud Pública , 2012,
Abstract: Introducción: el suicidio se ubica entre las 10 primeras causas de muerte en el mundo. La OMS estima que al menos 1 110 personas se suicidan cada día y lo intentan cientos de miles, independientemente de la geografía, cultura, religión, etnia, y alerta además, sobre el incremento de las tasas de suicidio como una tendencia creciente sobre todo en la población joven. Objetivo: valorar la ejecución del Programa de Prevención y Control de la Conducta Suicida en el municipio de Nueva Paz en el a o 2010. Métodos: estudio descriptivo y transversal. Se aplicaron cuestionarios, entrevistas, guías de observación y exploración de conocimientos sobre el Programa por un grupo de 65 trabajadores de la salud. Se establecieron criterios, indicadores y estándares para la evaluación de las variables de estructura, proceso y resultado. Resultados: el suicidio ocupó la séptima causa de muerte en el municipio y los intentos suicidas incidieron en el sexo femenino y en los grupos de 60 a os y más y de 10 a 19 a os. No existió un adecuado funcionamiento del Centro Comunitario de Salud Mental ni de los Equipos de Salud Mental. No se realizaron actividades de capacitación sobre el Programa y eran insuficientes los conocimientos para ejecutarlo. Las tarjetas de Enfermedades de Declaración Obligatoria carecían de calidad y el flujo de información era inadecuado. Se realizaba una deficiente dispensarización de los pacientes, en lo que incidía la baja calidad de la primera consulta, la no realización de interconsultas y la no periodicidad establecida en las visitas de terreno. Conclusiones: las deficiencias encontradas en la estructura y el proceso conllevaron a que la ejecución del Programa de Prevención y Control de la Conducta Suicida en Nueva Paz en el 2010, fuera inadecuada.

Mathematical modelling of the mass-spring-damper system - A fractional calculus approach
José Francisco Gómez Aguilar,Juan Rosales García,Jesus Bernal Alvarado,Manuel Guía
Acta Universitaria , 2012,
Abstract: In this paper the fractional differential equation for the mass-spring-damper system in terms of the fractional time derivatives of the Caputo type is considered. In order to be consistent with the physical equation, a new parameter is introduced. This parameter char-acterizes the existence of fractional components in the system. A relation between the fractional order time derivative and the new parameter is found. Different particular cases are analyzed
Suitability of the Composite Made of Multi Wall Carbon Nanotubes-Polyvinylpyrrolidone for Culturing Invertebrate Helix aspersa Neurons  [PDF]
Juan Bernal-Martinez, Rafael Godínez-Fernández, Alfredo Aguilar-Elguezabal
Journal of Materials Science and Chemical Engineering (MSCE) , 2017, DOI: 10.4236/msce.2017.52005
Abstract: Carbon nanotubes have been used as scaffolds for tissue engineering. However, the identification of these nanomaterials disperses in biological solutions and their direct interaction with nerve cells is still controversial. The aim of this work is to characterize the topographic and ultra-structural distribution of the composite made of multi wall carbon nanotubes-polyvinylpyrrolidone (MWCNTs-PVP) deposited on the Helix aspersa neurons and over glass coverslip. Scanning Electron Microscopy (SEM) and Confocal Microscopy (CM) studies were done to analyze the properties of such MWCNTs-PVP composite. The cerebral ganglion of Helix aspersa was treated and incubated with MWCNTs-PVP, fixing it in paraformaldehyde at 4% and was observed with SEM and CM. Although the nanotubes were not labeled or stained with fluorescent compounds, the MWCNTs-PVP deposited on glass and on nerve cells, was observed by the confocal microscope in the reflection mode. In SEM studies, it was observed that MWCNTs-PVP was attached to the surface on neurons. Moreover, in CM studies, it was possible to observe that MWCNTs-PVP was attached to the neuronal membrane, crossing the cell membrane and getting into the cytoplasm. These results support the hypothesis that carbon nanotubes interact with the neuronal cell membrane and can be useful for neuronal tissue engineering. In addition, these results open new alternatives for toxicological studies, in order to elucidate the cytotoxicity of MWCNTs-PVP composite in neurons and other excitable cells.

Abstract: The effect of the application of ethanolic extract of “Haden” mango seeds to increase the antioxidant and antimicrobial capacity of fresh-cut mango flesh was evaluated. Phenolic HPLC analysis revealed that gallic acid was the major identified compound in the ethanolic extract (586.68 mg/g). Fresh-cut mango was treated for immersion within the ethanolic extract, packed and stored at 5 during 15 days. The content of phenolic compounds, antioxidant capacity and microbial growth of the treated mango were evaluated during the storage. Compared with the controls the treated fruit presented the highest content of the total phenolic (7.4 times), flavonoids (3.1 times), and antioxidant capacity DPPH·, TEAC and ORAC (2.9, 2.3 and 2.8 times, respectively), and showed a microbial reduction of 80% of mesophilic plate count and 97% of total molds. This study demonstrates the potential of phenolic compounds derived from mango seed as antimicrobials and antioxidants.

Abstract: the development of health psychology in cuba has reflected the changes occurred in the society due to the revolutionary transformations, the organization of the national health care system and the maturing of the way of thinking and performance of the psychologist. these antecedents allowed introducing the work of this professional into the primary care institutions and modifying the concept of the role of this specialist in the hospital setting through his/her insertion not only in psychiatry but in every service, and extending his/her participation in the care of the health-disease process. the above-mentioned conditions imposed the need of postgraduate education and specialized and academic formation of psychology professionals, particularly in the health psychology branch. the training of these human resources within the health care sector has been gradually carried out thanks to the approval of three formative courses, that is, master′s degree in health psychology in 1993; the specialty of health psychology in 1995 and bachelor′s degree in psychology, health mention, in 2004. all these processes lead to the existence of a formative system of health psychology nationwide in the cuban medical university.
