Assessment of the ecotoxicity of phytotreatment substrate soil as landfill cover material for in-situ leachate management
2019
Phytotreatment capping in closed landfills is a promising, cost-effective, in situ option for sustainable leachate treatment and might be synergistically coupled with energy crops to produce renewable energy (e.g.: biodiesel or bioethanol). This study proposes to use 0.30 m of soil as growing substrate for plants cultivated on the temporary cover of closed landfills. Once the leachate phytotreatment process is no longer required, 0.70 m of the same soil would be added to attain the final top cover configuration. This solution would entail saving the costs of excavation and backfilling. However, worsening of the initial soil quality due to potential contaminant transfer from the liquid to th…
Effects of protein supplementation in fitness world: A 12-week cross-over studio
2020
The aim of this project was to evaluate the effect of isolated protein supplementation in young amateur athletes. Sixteen subjects aged between 20 and 30 were recruited for this study. Before to start sports performance was assessed at T0, in all subjects, using physical performance test and evaluated body composition. Therefore, the subjects were randomly assigned in two groups (group A and B) of 8 subjects each. The group A start to intake 30 g of protein powder diluted in water after each training session (3 times a week) for six weeks (T0) whilst the group B was the placebo. After 6 weeks (T1), the measurement were repeated for all subjects and the group A became placebo and the group B…
Effects of Mediterranean Diet Combined with CrossFit Training on Trained Adults’ Performance and Body Composition
2022
CrossFit is a high-intensity training discipline increasingly practiced in recent years. Specific nutritional approaches are usually recommended to maximize performance and improve body composition in high-intensity training regimens; notwithstanding, to date there are no targeted nutritional recommendations for CrossFit athletes. The Mediterranean Diet (MD) is a diet approach with a well-designed proportion of macronutrients, using only available/seasonal food of the Mediterranean area, whose health benefits are well demonstrated. No studies have evaluated this dietary strategy among CrossFit athletes and practitioners; for this reason, we tested the effects of 8 weeks of MD on CrossFit at…

A classroom intervention on Spanish grammar and writing: the use of the past tense with secondary school students / La intervención didáctica en el a…
2015
AbstractThis article presents an innovative experience which links grammar teaching with writing, following the premises of the Grammar Didactic Sequences (GDS) with one basic objective: to create a situation in which students learn to reflect on the language they use and are able to use these reflections to improve their writing. The GDS, focused on the use of past tense verb forms, was carried out with fourth-year secondary school students in Spain. This article highlights the difficulties experienced by students when using grammatical concepts as elements to control usage and the importance of revising texts in order to create metalinguistic awareness in a recursive didactic process: fro…

Estudio climático del exponente “n” de las curvas IDF: aplicación para la Península Ibérica
2009
El análisis de las precipitaciones máximas suele llevarse a cabo mediante curvas IDF (Intensidad-Duración-Frecuencia), que a su vez pueden expresarse como curvas IMM (Intensidades Medias Máximas). En este trabajo, hemos desarrollado un índice “n”, definido a partir del exponente que se obtiene de ajustar las curvas climáticas IDF a las curvas IMM. Dicho índice proporciona información sobre el modo en que se alcanzan las precipitaciones máximas en una determinada zona clim´atica, atendiendo a la distribuci´on temporal relativa de las intensidades m´aximas. A partir del an´alisis clim´atico del ´ındice “n”, en la Pen´ınsula Ib´erica se pueden distinguir grandes zonas caracterizadas por m´axim…
Delivering Freight, ASAP! Una applicazione mobile per l'apprendimento dei concetti di base sugli Automi a Stati Finiti
2015
Finite State Automata (FA) are a family of automata quite popular in the context of computational intelligence, as they allow representation of complex information and behaviour via graphs that are easy to design and execute. Every Theoretical Computer Science curriculum, be it administered to pure computer scientists or engineers alike, has a module on FAs that teaches how to design, build and run them, on top of some important theorems highlighting fundamental results. Despite that, students often find difficult to absorb FAs properly, and often they resort to learn their basic usage and example by memory. Delivering Freight ASAP! is a mobile game with a mission: promote the correct learn…
The chemistry of acetone at extreme conditions by density functional molecular dynamics simulations
2011
Density functional molecular dynamics simulations have been performed in the NVT ensemble (moles (N), volume (V) and temperature (T)) on a system formed by ten acetone molecules at a temperature of 2000 K and density ρ = 1.322 g cm(-3). These conditions resemble closely those realized at the interface of an acetone vapor bubble in the early stages of supercompression experiments and result in an average pressure of 5 GPa. Two relevant reactive events occur during the simulation: the condensation of two acetone molecules to give hexane-2,5-dione and dihydrogen and the isomerization to the enolic propen-2-ol form. The mechanisms of these events are discussed in detail.
