Callejerización: glosario de violencia
Minerva Gómez Plata
El Cotidiano , 2003,
Abstract: El artículo reflexiona sobre la violencia inscrita en el fenómeno callejero. Los ni os y jóvenes en situación de calle atraviesan un proceso de callejerización. Esta noción es concebida desde una gama de aspectos en su modo de vida, que revela una intrincada articulación con procesos colectivos del orden de las instituciones y la cultura de nuestra época. La callejerización como producto de un orden social que va más allá del margen familiar, involucrando desde el modelo económico hasta las visiones que prevalecen en torno al espacio de socialización de esta población: la calle. Victimizar y estigmatizar a los ni os en situación de calle será la expresión más cruel de la violencia hacia ellos.
Los derechos de la infancia, entre miedos y crueldades. Notas sobre los riesgos sociales en la infancia
Minerva Gómez Plata
El Cotidiano , 2006,
Abstract: El presente artículo intenta se alar algunos aspectos que obstaculizan el ejercicio de los derechos de la infancia. La crueldad que el mundo inflige a la infancia es ejemplificada en los llamados riesgos sociales, poniendo sobre la mesa las relaciones que el mundo establece con la población infantil. Es necesario subrayar las situaciones que ponen en riesgo el bienestar de la ni ez en un mundo donde la prioridad del mercado invisibiliza el dolor y la pobreza más indignante. Estas líneas tratan de partir de lo general a lo particular de las realidades que viven millones de ni os, concentradas en el término riesgo social .
Proposal for the Introduction of the Spatial Perspective in the Application of Global Sensitivity Analysis  [PDF]
Wenseslao Plata-Rocha, Montserrat Gómez-Delgado, Joaquín Bosque-Sendra
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.46055
Abstract: In any model, Sensitivity Analysis (SA) is a fundamental process to improve the robustness and credibility of the results, as part of validation procedure. Generally, SA determined how the variation in the model output can be apportioned to different sources of variations, and how the given model depends upon the information fed into it. Many complex techniques of SA have been developed within the field of numerical modeling; however, they have limited applications for spatial models, as they do not consider variations in the spatial distributions of the variables included. In this research, a variation in the implementation of a Global Sensitivity Analysis (E-FAST) is proposed in order to include the spatial level. For this purpose the conventional tools available in a raster Geographical Information System (GIS) are used. The procedure has been tested in a simulation of urban growth for the Madrid Region (Spain) based on Multi-Criteria Evaluation (MCE) techniques. The results suggest that the inclusion of the spatial perspective in the application of the SA is necessary, because it can modify the factors that have a decisive influence on the results.

Abstract: in a quantitative research study, the concentration and circulation of group of micro-organisms "phytoplankton" have been found trough the images of the ocean colour in the colombian caribbean sea. these images have been observed trough the sea star satellite. the method logical procedure was to collect a number of ocean images at the 1a level of the sensor seawifs. this only covered the geographical area of study and the seasons of the year. the selection criterion was to give priority to the absence of clouds in the area. afterwards, the images were analyzed to create mosaics in convenient periods of the to, in turn visualize the periodical changes of the micro-organisms. thus place with higher concentration of phytoplankton in the study site were identified. this led to quantitative analyses of the concentration level of the subject of study. to analyze the images analytic algorithms were used to fit the sensor. the atmospheric correction of the seawifs images was made with the seadas software to obtain levels two and three of the images. this was done to calculate the primary production of phytoplankton

New Lagrange multipliers for the time fractional Burgers' equation
A. R. Gómez Plata,E. Capelas de Oliveira
Physics , 2015,
Abstract: Using the fractional derivative, considered in the Caputo sense, we study an analytical technique associated with the variational iteration method for the fractional generalized $\alpha$-time Burgers' equation with $\alpha>0$ and obtain approximate solutions in particular cases $0<\alpha\leq 1$ and $1<\alpha\leq 2$.
Determination of Optimal Zones for Forest Plantations in the State of Mexico Using Multi-Criteria Spatial Analysis and GIS  [PDF]
Noel Bonfilio Pineda Jaimes, Joaquín Bosque Sendra, Montserrat Gómez Delgado, Roberto Franco Plata, Xanat Antonio Némiga, Luis Ricardo Manzano Solís
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43025
Abstract: This work aims to develop simulation models that allow locating adequate areas for forest plantations in the state of Mexico. It combines multi-criteria evaluation (MCE) techniques and geographic information systems (GIS) to analyze and simulate future scenarios for forest plantations under three major objectives: commercial production, restoration and protection, and agroforestry. Results demonstrate the potential of this method to integrate different variables of social, economic and environmental nature, and for solve some problems of forest activities and management by locating the most suitable areas for this forestal activity.
Culture Mixed-Sex and Monosex of Tilapia in Ponds in Mexico City  [PDF]
Jose Luis Gómez-Márquez, Bertha Pe?a-Mendoza, María del Carmen Alejo-Plata, José Luis Guzmán-Santiago
Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.62017
Abstract: In this study, the growth of Oreochromis niloticus both mixed sex and males sexually reversed were analyzed in concrete ponds in the FES Zaragoza, UNAM, under the environmental conditions of the Mexico City. The experiment was carried from May to November 2013, in two concrete ponds of 50 m2. Similar feeding regime and stocking density of fish were maintained for the culture systems. Different growth parameters like body weight, length, daily weight gain (DWG), specific growth rate (SGR), feed conversion rate (FCR), Fulton’s condition index (K) and survival were analyzed during six months culture period. It was found that culture with monosex males tilapias yielded the highest weight, length, DWG and SGR compared to mixed sex populations tilapias. Water quality was monitored along the experiment. Based on the results, there were statistically significant differences in size (W = 20942.5, p < 0.05) and weight (W = 21413.0, p < 0.05) between the divisions of the pond. The initial total length used was 1.2 cm and ended with 20.4 cm for monosex males, higher than mixed-sex population. The initial average body weight of the fish was 0.21 g and they recorded 192.2 g at the end of culture for monosex males. The weight-length relationship for both populations of fish was positive allometric. The percentage gain in body weight and total length averaged were 150% and 31.8% respectively. Specific growth rates in weight and length for monosex males were higher than mixed-sex population. Daily weight gain and size was similar in both populations. The FCR had a mean value of 1.9:1 for monosex males and condition factor (K) had an average of 1.45 for mixed-sex population. Water quality indicated good oxygenation (>5 mg/L), warm water (>20°C), productive (<100 mg/L CaCO3) and slightly basic (pH > 8). Acceptable growth of fish and a yield of 3 ton/ha/6 months were obtained in both two ponds; therefore, the culture of tilapia under conditions of Mexico City was recommended.
Ciencias básicas biomédicas y aprendizaje de la clínica en la formación de médicos en Cuba
Marta Pernas Gómez,Lourdes Guadalupe Arencibia Flores,Mayra A. Gari Calzada,Minerva Nogueira Sotolongo
REDU : Revista de Docencia Universitaria , 2012,
Abstract: A partir de un análisis histórico lógico del desarrollo curricular de la carrera de Medicina en Cuba en los últimos 50 a os y considerando el contexto nacional e internacional contemporáneo, se realiza una caracterización de las limitaciones actuales que le reconocen las autoras al enfoque didáctico que han caracterizado a las ciencias básicas biomédicas (CBB) como disciplinas académicas en su aporte a la formación integral de médicos generales en este país y se expone su apreciación acerca de las perspectivas de perfeccionamiento, en correspondencia con la convocatoria realizada por el Ministerio de Salud Públicapara la recuperación y fortalecimiento de la aplicación del método clínico en el ejercicio de la profesión por los médicos formados con el currículo cubano. La introducción reciente de la Morfofisiología como disciplina, donde se integran con enfoque transdisciplinario contenidos de Anatomía, Fisiología, Bioquímica, Histología y Embriología, ha constituido un cambio novedoso en el currículo de Medicina en nuestras universidades médicas, con aciertos y desaciertos, pero perfectible y pertinente. Se concluye que el aporte realizado por las CBB durante los últimos cincuenta a os a la formación de médicos en Cuba ha sido muy importante y para dar continuidad a esa contribución, se hace necesario que su perfeccionamiento no se realice de forma aislada, sino como parte de las transformaciones globales que demanda el currículo de esa carrera.

The authors stress the key role of the disciplines grouped as BBS in the development of professional skills for future integral and general physicians, which may answer a request of the Cuban Ministry of Health for the recovery and strengthening of the clinical method in medical practice use.This novel didactical approach has grouped the five formerly independent BBS – Anatomy, Physiology, Biochemistry, Histology and Embryology – into one discipline named Morphophysiology.
