Greenhouse gas emissions from membrane bioreactors
2018
Nowadays, it is widely accepted that wastewater treatment plants (WWTPs) are significant sources of greenhouse gas (GHG) emission, significantly contributing to anthropogenic sources of GHG emission. Among the GHG emitted from WWTPs, nitrous oxide (N2O) has been identified as the potentially major component, since its high global warming potential (GWP) is 298 times higher than that of Carbon dioxide (CO2) and also to its capability to react with stratospheric ozone, causing the ozone layer depletion. Up to now, most of the experimental investigations aimed at assessing the key mechanisms of N2O formation, as well as the operational conditions that can enhance its emission, have been carrie…

Lo spazio della città nelle declamazioni in lingua latina
2018
Latin declamations offer an extraordinary perspective to measure some spatial categories, such as, for example, the one concerning the 'scenography' that is the background on which the protagonists of the declamations move. In this sense emerges the fundamental role of the city as a place that, even in the indefiniteness that distinguishes these texts, not only animates the actions of the protagonists but frequently motivates their behavior.
ELEMENTO D’INTERFACCIA PER LA SIMULAZIONE DI PROCESSI DI DANNEGGIAMENTO IN MODO MISTO I/II NEI MATERIALI COMPOSITI E NELLE GIUNZIONI ADESIVE
2018
E’ stato sviluppato un elemento coesivo in grado di connettere e simulare la crescita delle cricche tra sottodomini di elementi finiti modellati in modo indipendente con mesh incompatibili. L'approccio si basa su funzioni di penalità e presenta numerosi vantaggi rispetto alle tecniche FEM convenzionali nelle simulazioni di delaminazione. Il più importante è la possibilità di rilasciare una porzione dell'interfaccia più piccola della lunghezza degli elementi finiti locali. Pertanto la delaminazione non avanza solamente rilasciando i nodi del modello FEM, una limitazione comune a molti metodi trovati in letteratura. È stato anche sviluppato un nuovo approccio per modellare la crescita delle c…
La riforma ottocentesca dei Quattrlo Canti di Palermo
2018
Il nuovo corso politico dell’Italia post-unitaria richiese ad ogni città con un passato illustre di confrontarsi con le altre, attraverso trasformazioni radicali e grandi opere pubbliche in grado di incidere sui servizi e sulla qualità urbana. Insieme a case operaie, bagni pubblici, mercati coperti e teatri, si intervenne nella riqualificazione degli assi monumentali, delle sedi stradali e delle architetture che vi affacciavano. Il forte abbassamento del suolo dei Quattro Canti obbligò ad una profonda trasformazione delle facciate seicentesche, secondo un progetto che coinvolse la città nel suo cuore tecnico ed intellettuale. Attraverso una inedita e ricca documentazione archivistica si ric…

MOOC : "ProtéiNNOV : Protéines végétales et Innovation"
2018
La prise de conscience d'une raréfaction des ressources en protéines animales dans les décennies à venir et la nécessité de produire plus durablement ces ressources alimentaires nous conduit à repenser aux autres sources de protéines, notamment les protéines d'origine végétale. Parmi les sources de protéines végétales, la plus employée comme substitut des protéines animales est le soja, mais le soja n'est pas la seule source de protéines végétales. Il est donc opportun de faire le point sur les autres sources de protéines végétales et sur leur utilisation. Le développement de nouveaux produits alimentaires riches en protéines végétales passe par la connaissance des atouts tant technologique…

Alnus glutinosa (L.) Gaertn. and Alnus cordata (Loisel) Duby as new sources of safe cosmetic and pharmacological anti-melanogenic agents
2018
The genus Alnus (Betulaceae) comprises many species with a long history in traditional medicines. The crude extracts and isolated compounds from Alnus species exhibit a wide spectrum of in vitro and in vivo pharmacological activities (1). Phytochemical investigations revealed the presence of diarylheptanoids, a class of natural products typically found in Alnus genus with two aryl groups joined by a heptane chain in the main skeleton that have drawn attention due to their multiple biological properties and their therapeutic potential (2). A previous study reported that oregonin and other structurally analogous diarylheptanoids isolated from the bark of A. hirsuta showed inhibitory effects o…

Les valeurs du soin, enjeux éthiques économiques et politiques
2018
International audience; Ce livre invite à réfléchir au système de soins en cherchant à concilier la valeur économique et la valeur intangible du soin. La préservation de la pensée éthique sur le sens du soin est indispensable à l'heure des contraintes gestionnaires.Le monde du soin est structuré et saturé par des valeurs de toutes sortes : celles des professionnels, surtout d'ordre éthique ou scientifique, celles des personnes soignées, d'ordre social, culturel ou familial. La valeur économique est aussi prégnante dans cet univers. Que vaut le soin ? Comment la valeur s'articule-t-elle au coût ? La réponse à ces questions ne se limite pas à déterminer combien coûte le soin. C'est l'ambition…
Empowerment en l’àmbit de la cooperació al desenvolupament
2018
Aquest article pretén ser una reflexió sobre el concepte de Cooperació al Desenvolupament i el seu significat en les relacions d’empowerment. Empowerment es refereix a un concepte desenvolupat en la Psicologia comunitària nord-americana que bàsicament es refereix a l’adquisició i / o apoderament de la capacitat de tenir control sobre la seva pròpia vida. El concepte d’«apoderament» pot aplicar-se a qualsevol grup que pugui identificar-se com a col·lectiu vulnerable socialment. No obstant això, el caràcter subjectiu i ambigu del concepte ha afavorit que el terme s’hagi estès de tal manera que s’hagi buidat de contingut. Malgrat això, el «empowerment» té un gran potencial per ser un instrumen…
Análisis de la atención sanitaria prestada a mujeres que sufren violencia de género

Reverse electrodialysis heat-engine: Case studies of improving energy efficiency through recovery of low temperature excess heat
2018
Reverse Electrodialysis (RED) is a technology for generating electricity from the difference in salinity between two solutions. RED is usually applied to natural water streams with different salinities, like seawater vs. freshwater. In the RED Heat-to-Power project we explore the option of using artificial water solutions operating in a closed loop where the difference in salinity is regenerated in a separation step powered by heat at temperature ranges between 60 and 100°C. We call this system Reverse Electrodialysis Heat Engine (RED HE). In this paper, first we summarise the possible system configurations and the overall amount of excess heat available in Europe for powering the RED HE pr…

The hetero-cubane structures of the heavy alkali metal tert-amyloxides [MOCMe2Et]4 (M = K, Rb, Cs)
2018
A series of alkali metal (Li–Cs) alkoxides of tert-pentanol (1,1-dimethylpropan-1-ol) have been prepared by reaction of the corresponding metal with the alcohol in n-hexane or n-heptane. The compounds were purified by vacuum sublimation and crystallised in n-hexane to produce crystals suitable for single-crystal X-ray diffraction studies. The structures of the potassium, rubidium, and caesium compounds revealed tetrameric units with additional intra- and intermolecular interactions between the metal atom and alkoxide methyl groups, increasing with the size of the metal involved.
Perspectives on Global Understanding in Ibero-American Countries

EUROscepticism and Monetary Security in Europe
2018
By deliberating on the correlations between the monetary security and the EUROsceptic views of the European citizenry and elites, this chapter addresses the problem of supranational monetary policy and the consequences it has for the economic security of the EU and its constitutive member states. The analysis starts with the introduction into the concept of EUROscepticism and its relations with the classical Euroscepticism. Then the second key term of the chapter is defined, which is the monetary security—nested in the general understanding of the economic security. Here, not only the author provides his own understanding of the monetary security, but also discusses its main levels, dimensi…
Regional Income Inequality in Spain 1860–2015
2018
How has regional economic inequality evolved since 1860? Is there a relationship between initial per-capita income and regional growth rates? Is there any relation between the evolution of regional inequality and the economic development process in Spain? In order to answer these questions, a number of different indicators of inequality are offered in this chapter. Then the patterns of convergence or divergence followed by Spanish regions from the mid-nineteenth century to the present are studied. Regional income inequality rose in the early stages of economic development and then declined. However, with high levels of development, around the 1980s, a change of trend is observed. In other w…
