The Effect of Mechanocatalytic Pretreatment on the Structure and Depolymerization of Willow

2020

In this study, the effect of a mechanocatalytic pretreatment on the structure of willow and sugar release from pretreated willow was explored. In the mechanocatalytic approach, the pretreatment consists of solvent-free impregnation with sulfuric acid and a mechanical treatment with ball milling. Willow sawdust and pretreated samples were analyzed with field emission scanning electron microscope and X-ray diffraction. The products in the sugar solution were determined as the total reducing sugars with the 3,5-dinitrosalicylic acid method and monosaccharides with capillary electrophoresis. According to the results, milling increased the sugar production, depending on the sulfuric acid load. T…

Investigation of a Gravel-Bed River’s Pattern Changes: Insights from Satellite Images

2021

Changes in river pattern have been documented in the literature. The recognition of islands and vegetated patches, which is indicative of the evolution processes, requires simultaneous information at different points and at different times and field studies are still difficult and scarce. The present work, focusing the attention on a gravel-bed river, explores the possibility to conduct a first-step pattern changes analysis by identifying the evolution of the morphological features and taking information of islands and vegetated patches from satellite images easily available from Google Earth. The study is conducted by combining the information taken from both the satellite images and the f…

Nasium : Sondage archéologique à Saint-Amand-sur-Ornain " Le Cul de Breuil "

2010

Ce rapport de fouille présente les résultats d'un sondage archéologique mené au cœur du site de Nasium, à l'interface entre l'oppidum celtique et l'agglomération antique. Le système de voirie qui relie ces deux , dans le prolongement d'une des portes principales de l'oppidum, a été ainsi révélé, associé à des structures à caractère funéraire ou rituel. La chronologie de ces vestiges, centrée sur les dernières décennies du Ier siècle avant J.-C., correspond à la période durant laquelle l'oppidum est abandonné au profit de la plaine alluviale de l'Ornain. Par ailleurs, la découverte de plusieurs centaines de clous de chaussure militaires et de céramiques d'origine italique pose la question du…

Room temperature synthesis of lanthanum phosphates with controlled nanotexture as host for Ln(III) through the Epoxide Route

2022

AbstractHerein, the Epoxide Route, a one-pot room temperature alkalinization method based on the reaction between a nucleophile and an epoxide, has been employed to synthesize LaPO4 in the form of a Rhabdophane phase. The intrinsic features of this synthetic approach allow the reaction to be followed by pH monitoring, making possible the identification of the different precipitation steps involved in the formation of the solid. Once demonstrated the effectiveness of this chemical methodology, the size and shape of the LaPO4 particles were controlled by varying the identity and proportion of the organic co-solvents employed to perform the reaction. By these means, crystalline particles with …

Carbon stocks in a 50‑year‑oldEucalyptus camaldulensisstand in Sicily, Italy

2015

Eucalyptus stands in semi-arid areas may contribute to enhance carbon (C) stocks in both biomass and soil. However, the limited information available is mainly focused on short-rotation plantations. In this study, the above- and below-ground C pools in five 50-year-old Eucalyptus camaldulensis Dehnh. stands planted on Miocenic evaporitic deposits in Sicily, Italy, with a xeric and thermic pedoclimate, were measured. Above-ground biomass was determined by partitioning and weighing branches, stem and leaves. Below-ground C pools included the determination of litter, root biomass, and soil organic and inorganic C. In terms of the above-ground biomass, the E. camaldulensis stand accumulated on …

Fosildiagénesis del anélido Rotularia spirulaea (Lamarck, 1818) (Polychaeta, Serpulidae) en el Eoceno del dominio pirenaico occidental

2018

The presence of the fossil polychaete Rotularia spirulaea (Lamarck, 1818) in Eocene deposits (middle Lutecian – upper Bartonian and (?) Priabonian) belonging to the western Pyrenean Domain is verified. In this paper, a fossildiagenetic study has been carried out. Fossils from three areas, corresponding to diff erent depositional settings, have been analysed. In area 1, sediments of the Ardanatz Sandstone and Ilundain Marls formations [Pamplona Basin and adjoining areas (Navarre)], were sampled. Here, the specimens of R. spirulaea  were not substantially affected by taphonomic reworking and the original microstructure of the carbonate tube is preserved. The test consists of a thick external …

Policy mixes for more vital legume value chains: Evaluation across competing policy frames

2021

Legumes receive increasing attention in sustainability transition research as they can contribute to more sustainable food systems. Previous research has established the need for policies relating to both production and consumption to tackle the marginalisation of legumes in European cropping systems and diets. In this paper, we apply the policy mix framework to food system transition and develop it further into an interpretive policy mix framework to evaluate policy mixes for more vital legume value chains. The interpretive policy mix framework facilitates a better understanding of competing policy frames in designing more consistent, coherent, and comprehensive policy mixes for transition…

Suomalaisen ruokaturvan ulottuvuudet : sisällönanalyysi ruokaturvasta julkisissa asiakirjoissa

2016

There has been wide public debate about global food security over the decades. Academic research has mainly focused on developing countries, which are most affected by food insecurity. In this context, only a little attention has been paid to the situation in developed countries like Finland. Contributing to filling this gap, this article studies how food security is understood and contextualized in Finland. Food security is explored by the four commonly used dimensions: 1) access, 2) availability, 3) stability (of supply) and 4) utilization. The research data consists of public reports related to food security as published by the ministries, organizations and research institutes. The analy…

Es ist ein Erlebnis, das man so in Mallorca nicht unbedingt erwartet : Präpositionsgebrauch bei ausgewählten Inseln

2018

Jopa äidinkieliset kielenkäyttäjät ovat usein epävarmoja kielen oikeakielisyyskysymyksissä. Tässä kandidaatintutkielmassa tutkittiin sitä, vastaako saksan kielen prepositioiden todellinen käyttö kieliopillisia normeja saarten nimien kohdalla ja mitkä tekijät mahdollisesti selittävät preposition valintaa. Teoria pohjautuu siihen, mitä kieliopeissa sanotaan prepositioiden käytöstä ja merkityksestä. Saksan kielessä saarten nimien kanssa käytetään prepositiota auf, kun halutaan vastata kysymykseen missä? ja ilmaista suunnan sijaan staattista sijaintia saarella. Jos saari on samanaikaisesti myös valtio, on mahdollista käyttää myös prepositiota in, joka tässä yhteydessä vastaa suomen kielen iness…
