Los vínculos del ingeniero Pablo Yver Ballester con la industria del gas británica (1902-1944)
At the beginning of the 20th century, the United Kingdom kept playing an important role in the European gas industry. The UK was regarded as a place where to seek better technological training in the sector and as a benchmark for equipment acquisition. Pablo Yvern would be an example of these statements.
Between 1902 and 1907, Pablo Yvern Ballester worked in the British industry in order to complete his training. While practicing as an engineer in the Spanish gas industry (1907-1944), his connections with his British counterpart intensified and resulted in the acquisition of the most advanced equipment he needed for his work.
The main technological contribution made by Pablo Yvern to the Spanish gas industry was his 1911 registered patent ‘Improvement the heat recuperators on gas furnaces’ A considerable part of his work as an engineer was based on it. We can find evidence of that during his employment by the British companies Gibbons Juniors and Gibbons Bros Ltd. His work as an engineer entailed the largest refurbishing and modernization of the production elements, especially furnaces, undergone in the first third of the 20th century.A principios del siglo XX, el Reino Unido continuaba siendo un referente para la industria del gas europea. Era el país más adecuado para obtener formación, tecnología y equipos. Pablo Yvern sería un ejemplo de estas afirmaciones.
Entre 1902 y 1907, Pablo Yvern Ballester trabajó en la industria británica para completar su formación. Mientras ejerció de ingeniero en la industria del gas española (1907-1944), sus relaciones con la industria británica fueron intensas ya que allí adquirió los equipos más avanzados que necesitaba para sus obras.
La principal aportación tecnológica a la industria del gas española de Pablo Yvern fue la patente que registró en 1911, denominada ‘Perfeccionamiento en los recuperadores de calor para hornos calentados por gas’. Sobre esta patente, fundamentó gran parte de su labor como ingeniero. En ella, hay indicios de la influencia de los conocimientos adquiridos durante su actividad en las empresas británicas Gibbons Juniors y Gibbons Bros Ltd. Su obra como ingeniero significó la mayor reforma y modernización de los elementos de producción, en especial los hornos, realizada en España en el primer tercio del siglo XX
An Experience of using B-Learning technologies to Teaching Optical Communications to Engineering Students
This paper deals with a pedagogical experience carried out with under-graduated students at the E.U.I.T. Telecommunications in Madrid, while coursing a subject of Optical Communications (OC). In this experience several B-Learning methodologies as well as technological resources have been combined, in order to get surpassing some difficulties well identified faced by the students of this subject. To find a reliable teaching strategy, the proposed methology have been introduced step by step along three academical courses, adding progressively new learning tools based on Information and Communication Technologies (ICT) [1,2]. The outcomes of the students assessments as well as the surveys carried out with them, have show a high improvement degree of the educative process in this specific subject of their curricula. New and more refined technologies based chiefly on remote laboratories will be tested along the next courses to overcome some issues not well surpassed ye
Virtual Teaching Approach for the Analysis and Planning of Wireless Communications Systems
One of the most important aspects in the field of engineering education is practical training. Very clear examples of this are the laboratories for training in design, development and measurement of electronic systems. However, in other areas of engineering, as for example in the case of communications, where the main objective is the systems analysis and planning, analytical solutions, if is possible, either to the simulation through approaches and algorithms are typically used. We have developed a set of tools for improving the knowledge and skills in wireless communications systems planning, for students of telecommunications engineering of the “Universidad Politécnica de Madrid”. These tools are of relatively simple use, and they are designed with the intention of a gradual process in learning through the establishment of various educational objective levels. In this paper are presented some of these tools developed and also there is realized an analysis of student assessment in the use of such solutions
Identidad de los currículos de los centros educativos rurales de la cuenca del Río Gaira
La situación de las escuelas rurales en América Latina no ha avanzado al mismo ritmo que lo vienen haciendo otros aspectos que inciden hoy de manera determinante en el campo educativo como son las ciencias, la tecnología y el los paradigmas curriculares. En Colombia la situación es la misma, aun cuando se reconocen algunos esfuerzos en los últimos diez años en este ámbito. Estas escuelas tienen poco desarrollo en al menos cinco aspectos fundamentales: La infraestructura, los procesos pedagógicos, los procesos de gestión, la relación con el contexto y la productividad. La articulación en estos cinco componentes, brinda la posibilidad de construir currículos más pertinentes y con verdadera identidad para estos sectores, los cuales rayan en la pobreza y la miseria como producto del abandono por parte del Estado y de las relaciones inequitativas presentes hoy en la sociedad colombiana. La construcción de unos currículos identitarios en estos ambientes rurales, deben tener en cuenta los aspectos socioculturales como punto de partida, los imaginarios de la nueva ruralidad, los enfoques sociopolíticos de las nuevas concepciones sobre territorio, la puesta en marcha de metodologías flexibles que garanticen el aprendizaje de los estudiantes y la productividad como ejercicio de emprendimiento de los niños y jóvenes del campo. De esta manera, los currículos en los sectores rurales para ser competitivos hoy, deben tener características fundamentales como la de ser abiertos, democráticos, inclusivos, crecimiento permanente, permeables, dialógicos, rizomáticos, flexibles, socioculturales, productivos y con un apoyo sobre las bases tecnológicas que circulan en el mundo y en los contextos donde se encuentra la escuela
Las estrategias publicitarias y comerciales de las empresas de gas y electricidad en Francia y España (1890-1918)
El artículo aborda la competencia entre las empresas de gas y electricidad en España y Francia entre 1890 y 1918 por el control del mercado de consumidores a través del estudio de las diversas estrategias publicitarias y comerciales empleadas por las compañías de ambos sectores. Junto a la implantación y la evolución de la producción y el consumo de ambas energías en uno y otro país, se analiza una muestra representativa de piezas publicitarias (carteles, anuncios impresos, folletos, catálogos…) que promocionaron toda una serie de aparatos y artículos de consumo que empleaban para su funcionamiento bien el gas, bien la electricidad.Este trabajo ha sido realizado gracias a la concesión del proyecto de investigación «El Gas en la Europa Latina: una perspectiva comparativa y global (1818-1945)» PID2020-112844GB-I00, financiado por el Ministerio de Ciencia e Innovación y Fondos FEDER (UE)

Prevalence trends of oral squamous cell carcinoma. Mexico City's General Hospital experience
Objective: Recent reports suggest an increase in oral squamous cell carcinoma (OSCC) frequency. To improve
programs in public health, it is necessary to understand the epidemiological conditions. The aim of this study was
to analyze the trend in gender, age, anatomic zone and OSCC stage from Mexico City's General Hospital patients
from 1990 to 2008.
Study design: A retrospective review of all OSCC cases diagnosed by the Pathology Department of the Mexico
City General Hospital was performed. Demographic data, in addition to anatomic zone and histological degree
of differentiation were obtained. Central tendency, dispersion and prevalence rate per 100,000 individuals were
determined.
Results: A total of 531 patients were diagnosed with OSCC; 58.4% were men, giving a male:female ratio of 1.4:1,
and the mean age was 62.5 ± 14.9 years. The predominant anatomic zone was the tongue (44.7%), followed by the
lips (21.2%) and gums (20.5%). The most frequent histological degree was moderately differentiated in 325 cases
(61.2%). The rates of OSCC prevalence showed similar patterns in terms across time. A significant correlation (P
= 0.007) between anatomic zone and age was observed.
Conclusion: According to our results, the prevalence of OSCC does not show important variations; however, a relation
-
ship between age and anatomic zone was observed. These data could be used as parameters for the diagnosis of OSCC
as well as for the development and dissemination of preventive programs for the early detection of oral cancer
