Modelo de comportamiento en sevicio para estructuras reticulares de hormigón. Parte II: Diagrama tensión- deformación para elementos fisurados a flexión

This paper presents a general methodology to adjust the coefficients defining a constitutive law for tensioned concrete to simulate, under serviceability conditions, the behaviour of cracked concrete members subjected to simple and combined bending (with axial compressive forces). Although experimental results could be used to obtain the mentioned objective, in this work the models proposed by the CEB are utilized, in order to obtain more general conclusions not subjected to specific experiments. A numerical parametrical analysis is performed to determine the more significant variables influencing the Tension-Stiffening effect and simplified closed-form solution is derived for rectangular sections. A systematic study has been to verify the ability of the method to simulate long-term effects. The methodology can be implemented as an initial process in a general model of analysis like the one presented in Part I

Cálculo de evaporadores de múltiple efecto en paralelo. Parte I: Modelo matemático y análisis del mismo

En el presente artículo se desarrolla el modelo matemático de un sistema de evaporadores de múltiple efecto operando en paralelo. Se analiza asimismo el modelo matemático para hallar el número de grados de libertad del sistema y la forma de consumir esos grados de libertad.

Cálculo de evaporadores de múltiple efecto en paralelo: Parte II. Resolución del modelo matemático y un ejemplo numérico

En el presente artículo se expone la resolución mediante calculador digital, del modelo matemático de evaporadores de múltiple efecto que fue publicado en Química e Industria, en el número del pasado mes de febrero.

El modelo Watson para un cambio de paradigma en los cuidados enfermeros

El cuidado representa la esencia y la función de los profesionales de enfermería, por lo que se hace una breve perspectiva histórica para situarnos en el momento actual, y argumentamos la necesidad de adecuar los cuidados y, por ende, la docencia y la investigación, al paradigma que pueda dar respuestas adecuadas a los procesos de salud/enfermedad. En este sentido, se describen brevemente las etapas históricas de enfermería y sus paradigmas, y se parte de una situación de un hombre con fibromialgia para contrastarlo con el modelo de cuidados de Jean Watson, el paradigma de la transformación y los saberes que se asocian con el pensamiento crítico.

Análisis de una propuesta de trabajo desde la perspectiva del modelo de convergencia europea

The work presented here describes a part of the experience carried out during the last two academic years in a course called New Technologies Applied to Education within the Teacher Training Studies of the Faculty of Education Sciences and Psychology of the University of Girona. It is a project that involves students working on a proposal closely related to their future professional lives. In it they simulate their intervention in a school staff meeting at which the introduction of ICT into the curriculum is being discussed. This proposal is presented in a WebQuest format. Various individual and group tasks allow the students to acquire knowledge about educational programmes and resources available on the web and to discuss their possible teaching applications in the context of a specific school situation, leading to an analysis of the curricular implications associated with the educational use of the ICT from the teacher’s perspective. During the last two academic years assessments by both the students and the teaching staff have been gathered in order to redesign the proposal and calculate the time necessary for the development of each task following the ECTS system. This proposal, although formulated within the context of current degree programmes, implies a way of working guided by the plans of European convergence (ECTS). In the future it is hoped to establish an interdisciplinary proposal focusing on various subjects of the degree leading to the development of some of the capabilities established in our university’s degree courses in Early Childhood and Primary Teacher Training following the plans of European convergence (ECTS)

¿Puede un modelo educativo intercultural combatir la discriminación y la xenofobia? = Can an intercultural education model combat discrimination and xenophobia?

In this article we present a qualitative study conducted with six indigenous and six mestizos from Intercultural University of Chiapas. The aim of the study is to exemplify the mutual perception between different ethno-linguistic groups, as well as the possible change occurred after the admission to the University. That is, opinions about the other group after and before entering the University. We conclude that a higher education intercultural model can promote mutual understanding and relationship between indigenous and mestizos and thus combat prejudices and stereotypes

Innovación y Aprendizaje: un nuevo modelo para la formación universitaria: ¿Por qué y para qué? = Innovation and Learning: a New Model for University Education: Why and for What?

The legislative reforms in university matters driven in recent years, beyond the provoked controversies, offer to universities the possibility to develop a new model in line with the European environment, focusing on quality aims and adapting to the socioeconomic current challenges. A new educational model centered on the student, on the formation of specific and transverse competitions, on the improvement of the employability and the access to the labor market, on the attraction and fixation of talent, is an indispensable condition for the effective social mobility and for the homogeneous development of a more responsible and sustainable socioeconomic and productive model
