The in vitro comet assay is a widely applied method for investigating genotoxicity of chemicals including engineered nanomaterials (NMs). A big challenge in hazard assessment of NMs is possible interference between the NMs and reagents or read-out of

L’écriture du savoir scientifique dans Il Saggiatore de Galilée

Autor: Ottaviani, Didier

Écrit en 1623 suite aux polémiques nées des discussions sur trois comètes apparues en 1618, Il Saggiatore de Galilée est un texte particulier dans l’œuvre galiléenne. Loin de présenter les principales avancées de son auteur, il s’agit d�

Irradiation de surfaces cométaires, application à l’origine de la matière organique des micrométéorites ultra-carbonées

Autor: Rojas Arispe, Julien

Micrometeorites are submillimeter extraterrestrial particles that represent the major source of interplanetary material accreted by the Earth each year. The analysis of micrometeorites allows to study the diversity of small bodies of the solar system

Sur les Histoires prodigieuses de Pierre Boaistuau

Autor: Lestringant, Frank

Les Histoires prodigieuses de Pierre Boaistuau puisent à des sources traditionnelles comme Pline l’Ancien, et prétendent allier goût du sensationnel et visée morale. Elles sont placées tour à tour sous le signe de Dieu et du diable, celui-ci

Diversité des sources distribuées dans les comètes : les cas du formaldéhyde et de la glycine

Autor: Hadraoui, Katia

Publikováno v: Astrophysique galactique [astro-ph.GA]. Université Paris-Est, 2020. Français. ⟨NNT : 2020PESC2061⟩

Formed since the creation of the Solar System, comets are of particular interest. They could have brought organic compounds to the primitive Earth that contributed to the chemical evolution that lead to the origin of life on Earth. Thanks to ground b

Spectrophotométrie de la matière extra-terrestre

Autor: Potin, Sandra

Publikováno v: Astrophysique galactique [astro-ph.GA]. Université Grenoble Alpes [2020-..], 2020. Français. ⟨NNT : 2020GRALU010⟩

Reflectance spectroscopy is one of the major techniques used to retrieve information on physical and mineralogical configuration of the surface of planetary bodies. However, the reflectance of a surface strongly depends on parameters unrelated to its

Contraintes isotopiques sur l'origine et la nature de la matière primitive dans le Système Solaire et sur la Terre jeune

Autor: Bekaert, David V.

Publikováno v: Ocean, Atmosphere. Université de Lorraine, 2020. English. ⟨NNT : 2020LORR0002⟩

The Earth formed some 4.5 Ga from the accumulation of dust, rocks and gas. The composition of these primitive materials is today recorded in meteorites. However, the origin of volatile elements within the atmosphere (e.g., H, C, N, O) remains poorly
