History of Spanish research in psychology seen through the scientific journals collected in the Web of Science during the period 2003-2012
2017
Resumen La abundancia y nivel de las publicaciones científicas constituye un indicador de la capacidad, trayectoria y calidad científica de un país, área temática o grupo de investigación. El grado de visibilidad internacional de una revista es un importante indicador sobre su calidad y cada vez es más considerado por las agencias de evaluación de los méritos científicos. Este estudio ofrece un análisis de la evolución de la actividad española en psicología, vista a través de su producción científica en las revistas de psicología recogidas en las bases de datos JCR del SSCI (Social Sciences Citation Index) y del SCI (Science Citation Index) durante 2003-2012. Los resultados indican un creci…
A Systematic review to identify the effects of biologics in the feet of patients with rheumatoid arthritis
2020
Background and objective: Ninety percent of patients with rheumatoid arthritis (RA) feel foot pain during the disease process. Pharmacological treatment of RA has a systematic effect on the body and includes: Nonsteroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs (DMARDs) and biologics. The objective of our review was to examine the impact of biologics on patients with RA ‘foot. Methods and material: A systematic review of randomized control trials and observational studies that evaluated the efficacy of biologics against other pharmacological treatment, and included a foot outcome measure. The search covered MEDLINE Ovid, Pubmed, CINAHL, Cochrane Library, Evidence Sear…
PRODUZIONE DI RIFIUTI A RISCHIO INFETTIVO E INDICI DI COMPLESSITÀ IN UN “CENTRO TRAPIANTI”
2015
Questo studio analizza la produzione di rifiuti a rischio infettivo in una grande struttura ospedaliera specializzata per le attività di trapianto: Ismett (Istituto Mediterraneo per i Trapianti e Terapie ad Alta Specializzazione), che si trova a Palermo. Sono state determinate le relazioni fra la quantità e la composizione dei rifiuti, da una parte; la complessità della struttura e la natura delle cure erogate, dall’altra. In letteratura si trovano regolarmente i risultati di ricerche sulla produzione di rifiuti a rischio infettivo nei più diversi Paesi del mondo; i dati pubblicati provengono quasi esclusivamente da Ospedali Generali, anche complessi e di Alta Specializzazione. Tali dati po…
Nitrate and nitrite in the diet: How to assess their benefit and risk for human health
2015
Nitrate is a natural constituent of the human diet and an approved food additive. It can be partially converted to nitrogen monoxide, which induces vasodilation and thereby decreases blood pressure. This effect is associated with a reduced risk regarding cardiovascular disease, myocardial infarction, and stroke. Moreover, dietary nitrate has been associated with beneficial effects in patients with gastric ulcer, renal failure, or metabolic syndrome. Recent studies indicate that such beneficial health effects due to dietary nitrate may be achievable at intake levels resulting from the daily consumption of nitrate-rich vegetables. N-nitroso compounds are endogenously formed in humans. However…
Total Absorption Spectroscopy of Fission Fragments Relevant for Reactor Antineutrino Spectra and Decay Heat Calculations
2016
Beta decay of fission products is at the origin of decay heat and antineutrino emission in nuclear reactors. Decay heat represents about 7% of the reactor power during operation and strongly impacts reactor safety. Reactor antineutrino detection is used in several fundamental neutrino physics experiments and it can also be used for reactor monitoring and non-proliferation purposes. 92,93Rb are two fission products of importance in reactor antineutrino spectra and decay heat, but their β-decay properties are not well known. New measurements of 92,93Rb β-decay properties have been performed at the IGISOL facility (Jyväskylä, Finland) using Total Absorption Spectroscopy (TAS). TAS is complemen…
Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts
2019
Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO3 , thus demonstrating the viability of this recycling solution. The a…

La spécialisation des productions et les spécialistes: Une introduction
2018
With the emergence of manufacturing based economies, specialised productions take on new dimensions during the Neolithic. Production networks progressively develop during the Neolithic and the Metal Ages and can be characterised according to their scale, how they are organised, the status of producers and the intensification of the trade of manufactured goods. This results on the one hand in mass production and on the other in the creation of highly technical objects on demand within a complex economic system of consumption and exchange. This is not seen as a linear progression but as a diversification of productions, products and know-how, the chronological and social contextualisation of …

Positron production using a 9 MeV electron linac for the GBAR experiment
2020
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. Staying below 10 MeV ensures no persistent radioactive activation in the target zone and that the radiation level outside the biological shield is safe for public access. An annealed tungsten-mesh assembly placed directly behind the target acts as a positron moderator. The system produces $5\times10^7$ slow positrons per second, a performan…
