This document provides a detailed introduction to the theoretical background against which the proposals of the National Curriculum Framework (NCF) were conceptualised. By presenting an overview of seminal reports and documents which highlight the local policy context together with recent EU policy directions, this document introduces the reader to the rationale which motivated the review of the existing curriculum. The first section concludes with a summary of the main tenets of the NCF summarising the major changes and challenges envisaged by the framework. The second section of this document presents the aims and general principles upon which the NCF is developed and which can be achieved and realised through the proposed learning areas and cross-curricular themes. The third and final section of this document invites the reader to reflect upon the implications which the proposed organisation of the curricular learning areas has for effective pedagogy, practice and evaluation procedures., peer-reviewed

Este texto es la transcripción de ese diálogo, en el que abordaron la relación de Mario Testa con los inicios de lo que posteriormente fue el Instituto de Saúde Coletiva de la Universidade Federal de Bahia (ISC-UFBA), su paso por Montes Claros, las experiencias de ambos sobre su formación, el proceso del Movimiento Sanitario y la Reforma Sanitaria Brasileña y distintos aspectos de la problemática actual del proceso salud-enfermedad-atención. Con este texto damos inicio a la serie Memoria e Historia, en la cual proponemos recuperar la memoria del campo de la Medicina Social y la Salud Colectiva desarrollada desde los años '60 en América Latina.

In service, railway tracks must withstand transverse and longitudinal forces arising from running vehicles and thermal loads. The mechanical design adopting any of the track models available in the technical literature requires that the strength of the track is fully characterized. In this paper, the results of an experimental research activity on the sleeper-ballast resistance along the lateral and the longitudinal directions are reported and discussed. In particular, the work is aimed at identifying the strength contributions offered by the base, the ballast between the sleepers, and the ballast shoulder to the global resistance of the track in the horizontal plane. These latter quantities were experimentally determined by means of an ad hoc system designed by the authors. Field tests were carried out on a series of track sections that were built to simulate scenarios in which the ballast was removed from the crib and/or the shoulder. The results of this study indicate that, as far as the scenarios here investigated are concerned, the strength percent contributions from the crib, the sleeper base and the shoulder are respectively equal to about 50%, 25%, and 25% in the lateral direction, and 60%, 30%, and 10% in the longitudinal one. Moreover, the comparison of the acquired data with literature results reveals that a detailed knowledge both of the testing conditions and the activated ballast failure mechanisms are needed in order to correctly use test data for design purpose.

Several studies have been carried out until now by various Research Agencies and Railway Administrations to quantify the effects of the track-bed geometrical characteristics on the transverse strength of the track. Unfortunately, not all the possible scenarios in terms of track components, track-bed cross profile, operating conditions etc. have been investigated and not all the relevant variables have been directly measured. Therefore data available from the literature have different degrees of reliability. With the aim of enlarging the knowledge on the track stability and covering much of the possible relevant scenarios, an experimental research program has been developed in the framework of a cooperation between RFI, Italcertifer and DII. In order to perform the investigation under quite general conditions and to reduce the experimentation costs, n. 28 significant scenarios have been identified and reproduced on as many independent track segments. By applying on each track segment a transversal load, the strength of the ballast-sleeper interface has been determined. The results relative to the first four scenarios are presented in terms of applied load vs. lateral track displacement diagrams and in more synthetic numerical tables.

Recent trends in the international photovoltaic (PV) sector indicate strong growth in terms of capacity and production, which is positively influencing the process of energy system decarbonisation. The aim of this review was to promote productive paradigms for a ‘closed cycle’ economy based on the enhancement of resource efficiency and the reduction of waste. To this end, the articulate framework for the management of end-of-life PV panels was analysed, highlighting strengths and weaknesses from the perspective of transitioning towards a circular economy. The conceptual framework is based on a comprehensive review and analysis of relevant literature to describe the main technological and environmental implications associated with PV energy production. Consequently, this paper highlights the most important critical elements, potential opportunities, and limitations deriving from the technological, managerial and organisational aspects of enhancing recovery and recycling rates. The review and the proposed framework might be useful for further research on this important yet complex topic.

In the present paper the design and construction choices of a test field for the ballast lateral resistance measurement, in order to produce data useful for the development of a numerical model able to simulate the service critical conditions of a continuous welded rail track, are described. Some construction details described herein allow to better understand the methodological approach followed in the design of experiments, the tests management philosophy as well as of the accuracy achieved in their implementation.

This text reproduces a speech given by Dr. Mario Testa on June 28, 1973 in the main hall of the Faculty of Medicine of the Universidad de Buenos Aires. The words of introduction preceding the text, written by Testa himself, provide the context of not only the historical moment the university was experiencing, just days after Rodolfo Puiggrós took office as the rector within the university's political overhaul, but also the meaning given to the project of pedagogical renovation. This project proposed redefining the relationship between the university and society, originating such projects such as the Instituto de Medicina del Trabajo (Institute of Occupational Medicine), the Instituto de la Madre y el Niño (Mother and Child Institute) and the Instituto de Patología Regional (Regional Pathology Institute) in the Faculty of Medicine; the Centro de Producción de Medicamentos de Base (the Center for Basic Drug Production) in the Faculty of Pharmacy and Biochemistry; and the Centro de Erradicación de Villas de Emergencia (Center for the Eradication of Shantytowns) in the Faculty of Architecture, among many others. Republishing these words, spoken almost 40 years ago, is a way of continuing to put into discussion the type of education and training health professionals receive with public funds.
