Carbon storage in soils by ancient and modern wheat varieties

2022

Les émissions anthropiques de gaz à effet de serre sont le principal moteur du changement climatique. Le plan Climat, issu de la COP 21 tenue à Paris en 2015, vise à atteindre la neutralité carbone à l'horizon 2050. Pour atteindre cette neutralité carbone, les gaz à effet de serre doivent d'abord être stabilisés, puis fortement réduits au cours du siècle prochain. Dans cette dynamique, l'initiative « 4 pour 1000 » fixe comme objectif d'atteindre un taux de croissance annuel du stock de carbone dans les sols de 0,4% par an. Ce stockage additionnel devrait compenser les émissions de CO2 dans l'atmosphère liée aux activités humaines. Les sols agricoles sont identifiés comme un compartiment de …

Social, occupational and cultural adaptation in Antarctica

2017

International audience; Objectives & Method: This study investigated psychological, social, occupational and cultural variables in adaptation to a one-year wintering in Antarctica with 13 international participants. Results & Conclusion: These psychosocial issues have important implications for pre-mission selection and training, monitoring and support of crews during the mission and post-mission readaptation highlighting the role of psychologists in stressful and extreme situations.

[Comparing two different techniques to assess the appropriateness of admissions provided in the emergency room of a pediatric hospital].

2007

Two different techniques aimed to assess the appropriateness of hospital utilisation were used to study the same sample of clinical records of admissions provided during 2001 by the emergency room of a pediatric sicilian hospital. The first technique estimated the '"high risk of inappropriateness" DRGs prevalence, according to the Decreto del Presidente del Consiglio dei Ministri of 29 Novembre 2001, and the second was the pediatric version of the Appropriateness Evaluation Protocol (AEP), based on clinical characteristics of patients and complexity of assistance provided. The comparison of results did not show any agreement between the two techniques (kappa= 0,031, C. I. 95%: from -0,001 t…

Detección precoz de la hipoacusia, influencia en el diagnóstico y en el tratamiento temprano

2021

Detección precoz de la hipoacusia, influencia en el diagnóstico y en el tratamiento temprano. INTRODUCCIÓN: La hipoacusia es el déficit sensorial mas frecuente en los países desarrollados. La prevalencia de cualquier grado de hipoacusia es de un 2-3 % de la población infantil y el 80% de las mismas, está presente al nacimiento. Los programa de screening auditivo (SA) se justifican por la alta incidencia de la hipoacusia y sus consecuencias devastadoras para el lenguaje cuando no se detecta precozmente. OBJETIVO: Establecer el número de niños diagnosticados de hipoacusia congénita gracias al SA en el hospital Universitario La Fe. Analizamos las técnicas utilizadas en el cribado, los parámetr…

Estimation of pollutant emissions from road traffic by image processing techniques. A case study in a suburban area

2013

This paper suggests a methodology based on the image processing technique able to automatically calculate the vehicle traffic and its components (light vehicles, heavy vehicles and motorcycles). The method also allows to evaluate instant vehicle speeds and, where necessary, to rebuild vehicle trajectories. Traffic data obtained through the procedure described below (capacities and speeds) can be also usefully applied to estimate pollutant emissions from vehicle traffic per year; therefore, the suggested method employs the algorithms defined with CORINAIR procedures, implemented in Copert 4 software. In order to evaluate how effective is the methodology, an experiment has been carried out in…

Mitigation of the impact of stellar activity on observations of transiting planets

2023

La tesi si concentra sulla quantificazione dell'impatto dell'attività stellare sulle osservazioni dei pianeti in transito e sull'identificazione di una metodologia per correggere questi effetti. In particolare, viene approfondito l'effetto delle macchie stellari, sia non occultate che occulte. La presenza di macchie sul disco stellare visibile può distorcere la curva della luce di transito primaria in modo dipendente dalla lunghezza d'onda, mimando la presenza di un'atmosfera. Per tener conto di questo effetto, la tesi presenta un metodo innovativo per stimare le proprietà delle macchie e la loro distribuzione dalle osservazioni fuori transito e, su questa base, correggere le curve di luce …
