La cultura escolar familiar i l'aprenentatge dels problemes socials
2022
La Geografia Humanística i també la de la Percepció s’han preocupat per la importància de les emocions i els filtres que condicionen la relació de les persones amb la realitat viscuda. La realitat dels centres escolars i de les aules són un espai significatiu per la creació d’una actitud en un alumnat que, en interpretar la realitat escolar, desenvolupa comportaments que condicionen el seu accés als elements culturals bàsics. El present treball s’interessa per les possibilitats del professorat de modular les actituds de l’alumnat definit com a perifèric per l’Administració, a través de la manera d’entendre el seu treball i de la forma com presenten els continguts a l’alumnat, per millorar l…
Perfil neuropsicológico de alcohólicos con alta densidad familiar de alcoholismo tras abstinencia prolongada: hallazgos preliminares
2002
INTRODUCCIÓN: Los estudios que han analizado el funcionamiento cognitivo de sujetos alcohólicos en función de la historia familiar de alcoholismo (11F+) han obteni¬do resultados poco consistentes, debido quizá a que el efecto de este factor puede verse oscurecido por la neurotoxicidad del alcohol. Esto puede evitarse comparando a los sujetos una vez que han abandonado el consumo de la sustancia. OBJETIVO: Determinar el perfil neuropsicológico de alcohólicos HF+ con más de tres años de abstinencia, con el fin de valorar la existencia y, en su caso, naturaleza de la afectación neuropsicológica. MATERIALY MÉTODOS: La muestra está formada por un grupo de sujetos alcohólicos abstinentes con al m…

Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Mechanical ventilation parameters in critically ill COVID-19 patients: a scoping review
2021
Abstract Background The mortality of critically ill patients with COVID-19 is high, particularly among those receiving mechanical ventilation (MV). Despite the high number of patients treated worldwide, data on respiratory mechanics are currently scarce and the optimal setting of MV remains to be defined. This scoping review aims to provide an overview of available data about respiratory mechanics, gas exchange and MV settings in patients admitted to intensive care units (ICUs) for COVID-19-associated acute respiratory failure, and to identify knowledge gaps. Main text PubMed, EMBASE, and MEDLINE databases were searched from inception to October 30, 2020 for studies providing at least one v…
Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome: Insights from the LUNG SAFE study
2020
Abstract Background Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence o…
Conversion of the Ca2+-ATPase from Rhodospirillum rubrum into a Mg2+-dependent enzyme by 1,N6-etheno ATP
1980
Nucleoside triphosphate hydrolysis of R.rubrum ATPase complexes can be changed from Ca2+-dependence to Mg2+-dependence by replacing ATP with 1,N6-etheno ATP. Four ATPase complexes which have been prepared by different procedures hydrolyze ATP and 1,N6-etheno ATP at different rates in dependence on the added metal ions. These differences allow an easy distinction of the various enzyme forms.
Efficacité interne de l'enseignement primaire aux pays de la Communauté Economique des Pays des Grands Lacs (CEPGL) : question approfondie sur le Rwa…
2011
This PhD study has been achieved with objective to carry out the level of internal efficiency of the primary education in the CEPGL countries and the progress reaches toward the education for all after the period of ethnic and armed conflicts. In addition, specifically for Rwanda, to underline the individual, families and school factors explanatory of the repetition and drop-out in the primary schools. The data of our analysis come from different reports of ministries, international organizations and publications of researchers. The analysis of the primary education inside CEPGL countries, by the indicators that document education supply and demand, show that, after the period of conflicts,…

Alien limit cycles near a Hamiltonian 2-saddle cycle
2005
Abstract It is known that perturbations from a Hamiltonian 2-saddle cycle Γ can produce limit cycles that are not covered by the Abelian integral, even when it is generic. These limit cycles are called alien limit cycles. This phenomenon cannot appear in the case that Γ is a periodic orbit, a non-degenerate singularity, or a saddle loop. In this Note, we present a way to study this phenomenon in a particular unfolding of a Hamiltonian 2-saddle cycle, keeping one connection unbroken at the bifurcation. To cite this article: M.
