The interactive effects of various nitrogen fertiliser formulations applied to urine patches on nitrous oxide emissions in grassland

2017

AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximated the N2O emission of urine and fertiliser N applied together (aggregated). Application of fertili…

Un OAD pour la gestion agroécologique des adventices

2018

Prod 2018-301 EA GESTAD INRA AGROSUP DOCT; Afin de réduire l’utilisation d’herbicides, nous avons besoin d’outils pour concevoir des stratégies de gestion des adventices économes en herbicides. Dans ce but, un outil d’aide à la conception de systèmes de culture réconciliant protection des cultures et des écosystèmes a été développé.Tout d’abord, la structure de ce nouvel outil d’aide à la décision (OAD) a été développée en interaction avec les futurs utilisateurs (conseillers et agriculteurs), via des enquêtes et des ateliers. Ensuite, le contenu biophysique a été utilisé sur le cycle des adventices dans les cultures, à partir du modèle de recherche FlorSys. Ce modèle est une « parcelle vir…

Insecure Firmware and Wireless Technologies as “Achilles’ Heel” in Cybersecurity of Cyber-Physical Systems

2022

In this chapter, we analyze cybersecurity weaknesses in three use-cases of real-world cyber-physical systems: transportation (aviation), remote explosives and robotic weapons (fireworks pyrotechnics), and physical security (CCTV). The digitalization, interconnection, and IoT-nature of cyber-physical systems make them attractive targets. It is crucial to ensure that such systems are protected from cyber attacks, and therefore it is equally important to study and understand their major weaknesses. peerReviewed

More educated, more mobile? Evidence from post-secondary education reform

2016

More educated, more mobile? Evidence from post-secondary education reform. Spatial Economic Analysis. This paper examines the causal impact of the level of education on within-country migration. To account for biases resulting from selection into post-secondary education, it uses a large-scale reform within the higher education system that gradually transformed former vocational colleges into polytechnics in Finland in the 1990s. This reform created quasi-exogenous variation in the supply of higher education over time and across regions. The results based on multinomial treatment effects models and population register data show that, overall, polytechnic graduates have a significantly highe…

Vins d’appellations et gastronomie régionale. La genèse bourguignonne d’un modèle novateur (années 1920-1930)

2016

Boire du vin au restaurant, le choisir ou le faire choisir en fonction du plat sélectionné, étudier la carte des boissons tout comme le menu, ou encore commenter les domaines et les millésimes, sont des actes totalement intégrés par les amateurs de gastronomie du XXIe siècle. Et même si les associations mets vins tendent à s’internationaliser, déguster un produit local avec un vin du cru reste un moment important pour nombre de personnes souhaitant visiter une région. Cette démarche, si commune aujourd’hui, résulte pourtant d’un processus historique finalement assez récent et dont l’évidence contemporaine n’a rien de manifeste historiquement. En France au début du XXe siècle seulement, et d…

Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…

2014

The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…
