Study and modelling of the passenger safety devices of an electric vehicle by finite elements
Abstract Electric mobility gets mainly involved quadricycles and cars. Between these two vehicle types there are differences in terms of stability, performance, cost, autonomy and safety. The authors studied the implementation of passenger safety devices on a prototype for an electric vehicle derived from a heavy quadricycle. A finite element analysis starting from experimental results was carried out in order to determine the effectiveness in case of frontal and side crashes
Valproic acid and phenobarbital blood levels during the first month of treatment with the ketogenic diet.
Objective – The aim of this study was to assess how the ketogenic diet
influences the blood levels of antiepileptic drugs in the first month of
treatment in a pediatric population with drug-resistant epilepsy. Methods
– The plasma concentrations of antiepileptic drugs were investigated in
an open study on 36 consecutive children and adolescents (20 males),
aged between 6 months and 16 years (mean age 4.7 years), who were
put on the ketogenic diet because of medically refractory epilepsy. The
plasma levels of antiepileptic drugs were determined 30 days and
immediately before the diet and on days 8, 15, 22 and 29 after the start
of the diet. The daily dose of each drug was not changed during the
first month of treatment, while the daily dose of benzodiazepines was
reduced by up to 30% if excessive sedation or drowsiness
occurred. Results – While plasma concentrations of phenobarbital did
not change in the first month on the ketogenic diet (mean increase of
2.3 mg ⁄ l 1.0), valproic acid showed a slight but not significant
decrease (mean decresase of 6.7 mg ⁄ l 3.2), 2 weeks after the start of
the diet. Conclusions – Adjustments in the daily dose of either drug
before the start of the diet do not however appear to be justified

Outreach activities, along with teaching and research, are part of the educational mission of higher education institutions. All three must be integrated into the policies and strategies of the institutions, interacting and enriching each other through channels of communication and mutual support. The objective of this work was to contribute to the training and development of agricultural producers, considering good agricultural practices. In order to do this, we worked in the districts of Serrezuela, Caminiaga and Sebastian Elcano. We worked to consolidate groups of producers and to promote behavioural changes; to this end, two aspects were exploited: i) the group dynamics, which consists of an active, participatory and reflective methodology through gradual, intentional and continuous work, and ii) the space-workshop, through which the learning of new behaviors related to livestock production was generated. The training, action and management of three groups of producers were consolidated. Producers and young coordinators of the groups created a space where knowledge was exchanged through an informal educational process.La extensión, a la par de la docencia y la investigación, forma parte de la misión educativa de las instituciones de educación superior. Todas deben estar presentes en las políticas y estrategias de las instituciones, interrelacionándose y enriqueciéndose recíprocamente a través de canales de comunicación y de apoyo mutuo. El objetivo de este trabajo fue contribuir a la capacitación y desarrollo de los productores agropecuarios, considerando las buenas prácticas agropecuarias. Para ello, se trabajó en las localidades Serrezuela, Caminiaga y Sebastián Elcano. Se trabajó en consolidar la formación de grupos de productores y promover cambios de conductas; para esto, se utilizaron dos ejes: la dinámica de grupo, que consiste en una metodología activa, participativa y reflexiva a través de un trabajo gradual, intencional y continuo y el espacio-taller, a través del cual se generó el aprendizaje de nuevas conductas referidas a la producción pecuaria. Se consolidó la formación, acción y autogestión de tres grupos de productores. Los productores y los jóvenes profesionales coordinadores de grupo generaron un espacio donde se intercambiaron saberes mediante un proceso educativo no formal
