In Situ, Airborne Instrumentation: Addressing and Solving Measurement Problems in Ice Clouds
2012
The workshop on in situ airborne instrumentation: addressing and solving measurement problems in ice clouds, June 25-27, 2010, Oregon, aimed to identify unresolved questions concerning ice formation and evolution in ice clouds, assess the current state of instrumentation that can address these problems, introduce emerging technology that may overcome current measurement issues, and recommend future courses of action to improve our understanding of ice cloud microphysical. Eleven presentations were made covering measurement challenges associated measuring the composition and concentration of all the modes of ice nuclei (IN), measuring the morphology, mass, surface, and optical properties of …
The role of VOC oxidation products in continental new particle formation
2008
Abstract. Aerosol physical and chemical properties and trace gas concentrations were measured during the QUEST field campaign in March–April, 2003, in Hyytiälä, Finland. Our aim was to understand the role of oxidation products of VOC's such as mono- and sesquiterpenes in atmospheric nucleation events. Particle chemical compositions were measured using the Aerodyne Aerosol Mass Spectrometer, and chemical compositions of aerosol samples collected with low-pressure impactors and a high volume sampler were analysed using a number of techniques. The results indicate that during and after new particle formation, all particles larger than 50 nm in diameter contained similar organic substances that…

Portrait de Zola en chroniqueur
2013
International audience; Il peut paraître difficile de concilier la figure du romancier naturaliste, soucieux de vérité, épris de science, désireux de réformer le champ littéraire par une œuvre dont les fondements auront par ailleurs été minutieusement théorisés, avec celle de l’improvisateur quotidien, soumis d’une part à l’actualité et de l’autre au public, contraint à une fantaisie permanente à l’aune de laquelle sera jugé son talent. Pourtant Zola a écrit de nombreuses chroniques, avant même de produire ses premiers romans naturalistes, puis au cours des premières années de la rédaction des Rougon-Macquart. Il a dû, pour ce faire, s’accommoder de deux traits constitutifs de la chronique …
Modelling molecular iodine emissions in a coastal marine environment: The link to new particle formation
2006
International audience; A model of iodine chemistry in the marine boundary layer (MBL) has been used to investigate the impact of daytime coastal emissions of molecular iodine (I2). The model contains a full treatment of gas-phase iodine chemistry, combined with a description of the nucleation and growth, by condensation and coagulation, of iodine oxide nano-particles. In-situ measurements of coastal emissions of I2 made by the broadband cavity ring-down spectroscopy (BBCRDS) and inductively coupled plasma-mass spectrometry (ICP/MS) techniques are presented and compared to long path differential optical absorption spectroscopy (DOAS) observations of I2 at Mace Head, Ireland. Simultaneous me…

Wildt, J.; Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes, climate and human health. The chemical and physical processes associated wit…
La inscripción de la ciudadanía en la cuba neocolonial (1902-1919) : Sucinta referencia histórico-jurídica
2021
This historical-legal account brieflycovering 17 years of civil registration activity carried out during the neocolonial period by Municipal Judges and Secretaries, specifically that related to registration of Cuban citizens)becomes considerably relevant to understand and to godeeper into the origins of this complex process, as well asto achieve a re-encounter with the history of those who passed through those times, currently a hidden history in the shadows of Civil Registration offices, but still alive and thus allowing us to find all the beauty that there was in it.
