Torrefied versus conventional pellet production – A comparative study on energy and emission balance based on pilot-plant data and EU sustainability …
2015
Abstract Torrefaction is an emerging technology which enables greater co-firing rates of biomass with coal. To date however there has been a lack of real production data from pilot-scale torrefaction plants. Without such data any environmental benefits of torrefied pellet production are difficult to quantify. In this study data on consumable inputs from a semi-industrial torrefaction plant and the physical properties of produced pellets are used to analyse energy input and air emissions of torrefied pellet production and product transport. EU sustainability criteria are used to compare CO2-equivalent emissions from torrefied and conventional pellet production starting from harvesting of log…
Amerikkalaiset ja Saksan pakolaiskysymys Weekly Information Bulletin -tiedotuslehdessä vuosina 1945-1953
2011
Toinen maailmansota johti vaikeaan pakolaisongelmaan, jonka keskuksena oli antautunut Saksa. Alueella oleskelleet pakolaiset tulivat hyvin erilaisista lähtökohdista ja pakolaisten määrä kohosi useisiin miljooniin. Ongelmien ratkaisu oli Saksaa miehittäneiden liittoutuneiden vastuulla. Tämän tutkielman aiheena on amerikkalaisten vuosina 1945–1953 Saksassa julkaiseman tiedotuslehden Weekly Information Bulletinin (WIB) kirjoittelu Saksan toisen maailmansodan jälkeisestä pakolaisuudesta. Tarkastelen tutkielmassani historiallis-kvalitatiivisen lähestymistavan avulla pakolaiskirjoittelun kokonaiskuvan lisäksi sen laatua ja sävyä, sekä arvioin miksi lehti kirjoitti juuri tällä tavoin. WIB:in tärke…
EGUAGLIANZA E WELFARE DEGLI IMMIGRATI: TRA SELF-RESTRAINT LEGISLATIVO E APERTURE GIURISPRUDENZIALI E CONTRATTUALI
2018
Il saggio analizza la tutela previdenziale e assistenziale di cui godono gli immigrati regolarmente soggiornanti in Italia alla luce dell’ordinamento internazionale, di quello europeo, e dei princìpi costituzionali. Nonostante le fonti «multilivello» sanciscano una tendenziale parità di trattamento tra cives e non cives, le legislazioni statali e regionali restringono la platea dei migranti beneficiari delle prestazioni soprattutto assistenziali. Tale orientamento restrittivo è in parte controbilanciato, sia dalla giurisprudenza di merito e costituzionale alla luce dei princìpi di ragionevolezza e non discriminazione, sia dall’intervento della contrattazione collettiva. The present work ana…
Impact of very low crop residues cover on wind erosion in the Sahel
2011
International audience; In the Sahel, with average annual precipitation in the order of 500 mm yr− 1, wind erosion occurs mainly on cultivated millet fields whose surfaces are only partially covered by crop residues. The impact of these residues on wind erosion was not clearly established. The objective of this study is thus to quantify the actual amount of crop residues in traditional Sahelian fields and to determine their impacts on wind erosion by reference to a bare surface throughout the seasonal cycle over several years. At the beginning of the year during dry season, Sahelian farmers use to "clean" their fields, i.e. cut and lay flat on the soil surface any millet stalks still standi…

Research Regarding the Use of Wheat Biodiversity for Obtaining some Cereal-Based Fermented Mashes
2012
International audience; Cereal-based fermented beverages are an opportunity to include probiotics and fiber in human nutrition. Nowadays, increasing the interest for rediscovering the benefits, on scientific basis, of traditional fermented beverages based on cereals. Fermented mashes based on different cereal grist, namely Braga in Romanian, is a healthy and nutritious beverage, a source for new functional products with beneficial effects on human health. Physical-chemical and sensorial characteristics of these beverages depend on the ingredients and method of preparation. In this article was analyzed the influence of the five varieties of wheat on the main physical-chemical and sensorial c…
Physical, chemical and mechanical evolution of the fuel-cladding interface in irradiated PWR fuel rods
2022
During the fuel irradiation in nuclear reactor, the fuel-cladding assembly is exposed to several irradiation-induced modifications. The fuel swelling coupled with cladding creep leads to a contact between the fuel and the cladding. The oxygen transport from the UO2 fuel to the zirconium layer induces progressively the Zr-cladding oxidation. This oxidation is initially local with the formation of islets. Then, with the increasing burnup of the fuel, it conducts to a continuous layer of about 8-µm thickness, localized at the fuel-cladding interface. At high burnup, zirconia growths anchor themselves in the periphery of the fuel (which is restructured) leading to pellet/cladding interlocking. …
Et si une impasse de désherbage en agriculture de conservation des sols vous poussait à retravailler le sol ? Quelle intervention choisiriez-vous ?
2019
National audience; En Agriculture de Conservation des Sols (ACS), la perturbation minimale du sol est l’un des trois prin-cipes. Si l’impasse se fait sentir mieux vaut repenser le système que de laisser le mur se rapprocher à grands pas. Trois types de gestion d’interculture (Labour, travail superficiel (TCS) et semis direct avec glyphosate (SD)) ont été comparés sur des parcelles conduites sans labour depuis 17 ans dont les 7 dernières années en ACS sur le domaine de l’INRA de Dijon avant implantation d’un blé, sur un dispo-sitif en bandes répétées sur quatre parcelles. Des relevés de flore adventice, rendement et compo-sante de rendement ont été faite. Les densités moyennes sont faibles p…
