La scolarisation féminine à Djibouti
2012
A la croisée de la sociologie du genre, de la sociologie de l'éducation et de l'anthropologie politique, cette recherche s'intéresse à la complémentarité des approches disciplinaires et méthodologiques au travers d'une étude sur les élèves de Djibouti pour sortir d'une "lecture en négatif" sur la scolarisation des filles limitée en contexte africain. A la suite de ce travail d'immersion sur lequel a reposé cette recherche, ce sont cependant les angélismes qui se cachent derrière la promotion de l'éducation des filles africaines qu'il convient d'interroger et qui donnent à mieux comprendre la persistance des thèses "afropessimistes" dans les rapports d'experts ou la littérature scientifique.
Caractérisation quantitative de la pulvérisation de pesticides par imagerie
2015
In recent years, advances in plant protection have contributed considerably to increasing crop yields in a sustainable way. Easy to apply and rather inexpensive, pesticides have proven to be very efficient. However, when pesticides are applied to crops some of the spray may not reach the target, but move outside the intended spray area. This can cause serious economic and environmental problems. Most of the pesticides are applied using agricultural sprayers. These sprayers use hydraulic nozzles which break the liquid into droplets with a wide range of droplet sizes and velocities and determine the spray pattern. Small droplets are prone to wind drift, while large droplets can runoff from th…
Larisa Maksimova on Implication, Interpolation, and Definability
2018
This edited volume focuses on the work of Professor Larisa Maksimova, providing a comprehensive account of her outstanding contributions to different branches of non-classical logic. The book covers themes ranging from rigorous implication, relevance and algebraic logic, to interpolation, definability and recognizability in superintuitionistic and modal logics. It features both her scientific autobiography and original contributions from experts in the field of non-classical logics. Professor Larisa Maksimova's influential work involved combining methods of algebraic and relational semantics. Readers will be able to trace both influences on her work, and the ways in which her work has influ…
Effect of substrate improvement on optimising biogas yield from anaerobic digestion
2014
Masteroppgave i fornybar energi ENE 500 Universitetet i Agder 2014 The anaerobic digestion process involves the decomposition of the organic matter to yield biogas; gas that is mainly composed of methane and carbon dioxide with traces of some other gases. This process is used for different purposes including municipal waste treatment, wastewater treatment, fertilizer production, and farm wastes disposal as well as energy production. It is accomplished in three main stages; hydrolysis, acidogenesis and methanogenesis with each of the stages achieved by specific microorganisms that are active in limited ranges of operational and environmental conditions. These conditions are controlled to ach…
Photoactivity of Nanostructured TiO2 Catalysts in Aqueous System and their Surface Acid-Base, Bulk and Textural Properties
2007
This work reports on the characterisation and determintion of the photocatalytic activity of some TiO2 catalysts prepared using TiCl4 as precursor. The samples, consisting of suspensions, dispersions or powders of nanonstructured anatase or rutile phases, were obtained in very mild conditions, i.e., by boiling the solution obtained after hydrolysis of TiCl4 at atmospheric pressure: it is worth noting that no calcination was necessary to obtain photoactive phases. The samples were characterised by X-ray diffraction (XRD), determination of the BET specific surface area (SSA), scanning electron microscopy (SEM) observations and diffuse reflectance spectroscopy (DRS). FT-IR spectroscopy was use…
I diritti degli animali
2022
Il contributo affronta il tema dei diritti degli animali nell'ambito delle opere di Paolo Cendon, analizzandolo nel quadro delle fragilità esistenziali. Per danno da perdita dell’animale di affezione si intende, infatti, il danno non patrimoniale, di tipo esistenziale, derivante al proprietario dalla perdita o dal ferimento dell’animale di affezione, capace di caratterizzare e, talvolta, dominare, del tutto, la rete affettiva familiare. Non si tratta, cioè, di risarcire la lesione di un diritto alla vita dell’animale, bensì di compensare la lesione del diritto alla relazione affettiva intrattenuta con l’animale, nell’ambito della quale l’individuo può esplicare la propria personalità relazi…
The Antioxidant Potential of White Wines Relies on the Chemistry of Sulfur-Containing Compounds: An Optimized DPPH Assay
2019
The DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay is an easy and efficient method commonly used to determine the antioxidant capacity of many food matrices and beverages. In contrast with red wines, white wines are poorer in antioxidant polyphenolics, and the more hydrophilic sulfur-containing compounds in them may contribute significantly to their antioxidant capacity. The modification of the classical DPPH method, with a methanol-buffer and the measure of EC20 (quantity of sample needed to decrease the initial DPPH concentration by 20%) has shown that sulfur-containing compounds such as cysteine (0.037 ±
La scolarisation maternelle à deux ans : analyse des effets pédagogiques et sociaux
1992
International audience; Le système éducatif français fait actuellement l'objet de pressions pour que soit étendue la scolarisation maternelle à l'âge de deux ans. Ces pressions sont fondées notamment sur l'argument que le milieu scolaire pourrait être un substitut efficace au milieu familial, en particulier lorsque celui-ci n'appara\ⁱt pas procurer à l'enfant les stimulations suffisantes. Concernant le fonctionnement du système scolaire, les cas ont été nombreux dans lesquels il s'est révélé exister une divergence nette entre les opinions "communes" et les faits objectivement mesurés, pour qu'il appraisse souhaitable de ne pas s'en tenir aux opinions. Sur cette question des effets de la mat…

The Averinga’s Edicola and the Cult of Water in Palermo. From Knowledge to Valorisation
2018
Si descrive un approccio multidisciplinare allo studio di un singolare monumento storico, l’Edicola dell’Averinga, che versa attualmente in gravi condizioni di degrado; questa costruzione fu realizzata nel 1587 dal Senato Palermitano a protezione delle acque della sorgente Ayn Rutah (nome arabo di Averinga) che sgorgavano proprio al suo interno e che da qui venivano raccolte e incanalate verso i fertili giardini, le abitazioni che si trovavano in prossimità delle mura cittadine e alcune delle più importanti fontane della città storica. La più antica descrizione a noi pervenuta della zona in cui è sita l'Edicola, la cosiddetta depressione Danisinni, appartiene al geografo iracheno Al-Qaim Mu…
