Large river deltas across the globe are under increasing economic and environmental pressure due to overpopulation, climate change, and rising sea levels. River catchment sediments and associated discharge feed delta systems providing nutrients that not only enable higher yields in rice production but also the potential for flooding. Indeed, rice p...
Ce dossier thématique met en perspective les données et prévisions scientifiques, souvent inquiétantes, concernant les impacts socio-environnementaux du changement climatique dans le Pacifique Sud avec des travaux qui analysent comment les populations de cette région les appréhendent – à la fois en tant qu'ensemble de phénomènes physiques et en tan...

Recent robotic missions to Mars have offered new insights into the extent, diversity and habitability of the Martian sedimentary rock record. Since the Curiosity rover landed in Gale crater in August 2012, the Mars Science Laboratory Science Team has explored the origins and habitability of ancient fluvial, deltaic, lacustrine and aeolian deposits ...
Recent sedimentary and morphological changes at the new mouth of Medjerda-River (Gulf of Tunis) are investigated using a multiproxy approach of sediment cores complited by 210Pbex and 137Cs method dating. The subject of the study is to focus on surveying the sedimentary evolution of Medjerda-Raoued Delta caused by the human intervention in the mana...
In no other country, perhaps, is the identification between water, irrigation, and agriculture as strong as in Egypt. Several phases of agrarian and technical change throughout its long history have taken Egypt to a situation where farmers grow between one to three crops a year on 3.78 million ha after lifting water from canals and drains, and some...
Após a intensificação das atividades antrópica no século passado, as concentrações de formas de nitrogênio reativo (Nr) na atmosfera têm aumentado drasticamente [1]. O aumento desses elementos na atmosfera pode trazer impactos para os ecossistemas, para a saúde e para o clima. Ainda, a deposição atmosférica de Nr pode aumentar a concentração de nit...
O sistema DELTA é um sistema de amostragem atmosférica de longo prazo para gases e aerossóis que utiliza tubos adsorventes (denuderes) de vidro, revestidos com soluções adsorventes para a captura dos gases, e filtros, revestidos com soluções reagentes para captura de aerossóis. O sistema de bombeamento é inserido, externamente, após a sequência de ...
The MiniBooNE large axial mass anomaly has prompted a great deal of theoretical work on sophisticated Charged Current Quasi-Elastic (CCQE) neutrino interaction models in recent years. As the dominant interaction mode at T2K energies, and the signal process in oscillation analyses, it is important for the T2K experiment to include realistic CCQE cro...
