Amparo García Ramón
Foro de Profesores de E/LE , 2010,
Abstract: En la ense anza de segundas lenguas, la pronunciación ha quedado,generalmente, relegada a un segundo plano. Al intentar se alar las causas de este hecho,se ha destacado como una de las principales la inseguridad de los profesores, quienes suelen considerar que es indispensable poseer amplios conocimientos de fonética para poder ense ar este aspecto de la L2. No se ha prestado tanta atención, en cambio, a la reticencia de los propios estudiantes a aprender la pronunciación. Es habitual que los aprendices se muestren escépticos, en cierta medida, ante sus propios errores: no acaban de creer que sus emisiones no se ajustan al modelo de corrección presentado por el profesor, puesto que no perciben las diferencias fonéticas que, en su lengua, carecen de función distintiva.
Lithium aluminosilicate reinforced with carbon nanofiber and alumina for controlled-thermal-expansion materials
Amparo Borrell, Olga García-Moreno, Ramón Torrecillas, Victoria García-Rocha and Adolfo Fernández
Science and Technology of Advanced Materials , 2012,
Abstract: Materials with a very low or tailored thermal expansion have many applications ranging from cookware to the aerospace industry. Among others, lithium aluminosilicates (LAS) are the most studied family with low and negative thermal expansion coefficients. However, LAS materials are electrical insulators and have poor mechanical properties. Nanocomposites using LAS as a matrix are promising in many applications where special properties are achieved by the addition of one or two more phases. The main scope of this work is to study the sinterability of carbon nanofiber (CNFs)/LAS and CNFs/alumina/LAS nanocomposites, and to adjust the ratio among components for obtaining a near-zero or tailored thermal expansion. Spark plasma sintering of nanocomposites, consisting of commercial CNFs and alumina powders and an ad hoc synthesized β-eucryptite phase, is proposed as a solution to improving mechanical and electrical properties compared with the LAS ceramics obtained under the same conditions. X-ray diffraction results on phase compositions and microstructure are discussed together with dilatometry data obtained in a wide temperature range ( 150 to 450 °C). The use of a ceramic LAS phase makes it possible to design a nanocomposite with a very low or tailored thermal expansion coefficient and exceptional electrical and mechanical properties.
Evaluation of a Teaching Sequence Regarding Science, Technology and Society Values in Higher Education  [PDF]
María Amparo Oliveros, Alejandra García, Benjamín Valdez
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.616179
Abstract: This work shows the results of a teaching-learning sequence applied to the concept of the nature of science and technology implemented on manufacturing technology engineering students at Autonomous University of Baja California, Mexico, during the academic period 2012-2013. The sequence was implemented to the course of Applied Human Values, on which students ponder and debate on principles of science and technology; taking as main objective to identity student beliefs on ethics, and values and assumptions of science. The Methodological design is quasi-experimental, pre-post-test without controlling group. The study allows identifying a slight improvement in the engineering student beliefs about the aspects of science, technology and society that are being evaluated.

Abstract: Interaction between insect herbivores and host plants can be modulated by endogenous and exogenous compounds present in the source of food and might be successfully exploited in Colorado potato beetle (CPB) pest management. Feeding tests with CPB larvae reared on three solanaceous plants (potato, eggplant and tomato) resulted in variable larval growth rates and differential susceptibility to Bacillus thuringiensis Cry3Aa toxin as a function of the host plant. An inverse correlation with toxicity was observed in Cry3Aa proteolytic patterns generated by CPB midgut brush-border membrane vesicles (BBMV) from Solanaceae-fed larvae, being the toxin most extensively proteolyzed on potato, followed by eggplant and tomato. We found that CPB cysteine proteases intestains may interact with Cry3Aa toxin and, in CPB BBMV from larvae fed all three Solanaceae, the toxin was able to compete for the hydrolysis of a papain substrate. In response to treatment with the JA-dependent plant inducer Hexanoic acid (Hx), we showed that eggplant reduced OPDA basal levels and both, potato and eggplant induced JA-Ile. CPB larvae feeding on Hx-induced plants exhibited enhanced Cry3Aa toxicity, which correlated with altered papain activity. Results indicated host-mediated effects on B. thuringiensis efficacy against CPB that can be enhanced in combination with Hx plant induction.

Proceso de imágenes médicas
Ramón García Rochin
Salud en Tabasco , 2000,
Abstract: El uso de herramientas para procesar imágenes en nuestro escritorio cada día es más común. Tenemos la tecnología disponible pero necesitamos capacitarnos más para hacer un buen uso de ella ya que el valor de la tecnología no está en poseerla sino en el uso que se le dé. El objetivo de éste artículo es mostrarle a la comunidad médica que usa imágenes de diferentes fuentes (Rayos-X, Ultrasonografía, Resonancia Magnética, Tomografía Axial Computarizada, Endoscopio, etc.) las tecnologías disponibles a nuestro alcance y los grandes beneficios que esto le traerá en la práctica diaria de la medicina.
EL TESTIMONIO DE LAS PARTES EN JUICIO PROPIO: ANáLISIS HISTóRICO COMPARATIVO A PARTIR DE LAS EXPERIENCIAS DE INGLATERRA Y AUSTRIA
Ramón García Odcers
Ius et Praxis (En línea) , 2012,
Abstract: El sujeto mejor informado de los hechos deducidos en el juicio es normalmente la parte misma, sin embargo, por el interés personal que tiene en los resultados del caso, también puede ser la prueba menos confiable. La disyuntiva de los sistemas de justicia es utilizar o no esa valiosa información. La reforma al proceso civil chileno, en materia de utilización de ese saber, ha sido puesta en el debate, ya que el Proyecto de Nuevo Código Procesal Civil contempla, en forma expresa, la posibilidad de que las partes declaren libremente en su propio juicio. Este trabajo presenta una perspectiva favorable a la reforma en este punto, a partir de un análisis histórico que confronta la realidad procesal chilena con dos experiencias relevantes del derecho comparado. Se demostrará que la tendencia histórica, orientada a proporcionar una mayor racionalidad a los sistemas probatorios, es favorable a este instituto. El desarrollo de la libertad probatoria, la oralidad, una mayor confianza hacia el juzgador y la eliminación de prejuicios abstractos y formalistas, constituyen los hilos conductores de este proceso. The parties are the better informed of the facts deduced at trial, but at the same time, for the personal interest they have in the outcome of the case, /may also be the less reliable evidence. The dilemma of the judicial systems is to use or not that valuable information. The Chilean civil process reform, in the use of this knowledge has been put into the debate. This paper presents a favorable outlook for this reform, from a historical analysis of the party witness rule evolution. With regard to the existing regulation on this subject in our procedures, we will analyze two relevant experiences of comparative law. It will be shown that this evolution, is inserted in a global historical trend that began several centuries ago, aimed at providing a more rational evidentiary systems to ensure a better determination of the facts. The development of free proof, orality, greater confidence in the adjudicator body, and the abstract and formal prejudices elimination, are the threads of this process.
La educación desde la perspectiva de género [The education from the perspective of gender]
Ramón García Perales
Ensayos : Revista de la Facultad de Educacion de Albacete , 2012,
Abstract: Resumen: Son numerosos y variados los aspectos sociales y culturales que influyen en nuestro comportamiento cotidiano. De esta forma, aparecen un arraigo de concepciones tradicionales sobre los diferentes roles que les corresponde a hombres y mujeres en la sociedad y que influyen de manera notable en su forma de pensar y de vivir. Debido a ello, el entorno escolar se configura como un ámbito de actuación determinante en la búsqueda de un equilibrio entre ambos sexos. Para ello, desde los centros se fomentan y desarrollan medidas y actuaciones en vías del logro de una igualdad de oportunidades real y generalizable a todos los ámbitos de la vida en los que los sujetos se desenvuelven. Además, es importante se alar la influencia tan importante (muchas veces “oculta”) que ejercen los propios materiales didácticos y los medios de comunicación a través de su lenguaje audiovisual. Por último, es preciso dedicar una mención especial a las alumnas con altas capacidades, “olvidadas” de las prácticas escolares enriquecedoras en una sociedad en plena búsqueda de una total igualdad de oportunidades entre hombres y mujeres. Abstract: They are numerous and varied the social and cultural aspects that influence in our daily behavior. This way, they appear an I root of traditional conceptions on the different lists that it corresponds men and women in the society and that they influence in a remarkable way in their form of thinking and of living. Due to it, the school environment is configured between both as an environment of decisive performance in the search of a balance sexes. For it, from the centers they are fomented and they develop measures and performances in roads of the achievement from a real and generalizable equality of opportunities to all the environments of the life in those that the fellows are unwrapped. Also, it is important to point out the influence so important (many times it hides) that exercise the own materials didactic and the mass media through their audiovisual language. Lastly, it is necessary to dedicate a special mention to the students with high capacities, forgotten of the enriching school practices in a society in full search of a total equality of opportunities between men and women.
El doble subjetivo y el enigma de la locura criminal en / Babel-ville / de Joseph Bialot
Ramón García Pradas
?édille : Revista de Estudios Franceses , 2011,
Abstract: Through this article we would like to explore not only the image of the double but also its functions in Bialot’s novel Babel-ville. To do so, we would like to take into account those theoretical studies that Jung, Rank or Jourde and Tortonese (among others) have carried out on this subject from a literary and s psychological point of view. We will analyse the main character’s criminal madness as a procedure to generate a double which does not match up with the figure of a human being, as if our main character’s pulsions (his unconscious part) were not human at all. So our main purpose in this article will focus on the study of Bernard, the main male character of Bialot’s novel, Babel-ville, which should be considered as a good sample of what literary criticism is inclined to call black novel. That’s why we will try to see how Babel-ville sticks to the main characteristics of these literary manifestations, which, by the way, seem to appear really suitable when an author tries to look into the enigmatic mystery of the double-being in literature.
