Unveiling microbial structures during raw microalgae digestion and co-digestion with primary sludge to produce biogas using semi-continuous AnMBR sys…
2020
[EN] Methane production from microalgae can be enhanced through anaerobic co-digestion with carbon-rich substrates and thus mitigate the inhibition risk associated with its low C:N ratio. Acclimated microbial communities for microalgae disruption can be used as a source of natural enzymes in bioenergy production. However, co-substrates with a certain microbial diversity such as primary sludge might shift the microbial structure. Substrates were generated in a Water Resource Recovery Facility (WRRF) and combined as follows: Scenedesmus or Chlorella digestion and microalgae co-digestion with primary sludge. The study was performed using two lab-scale Anaerobic Membrane Bioreactors (AnMBR). Du…
The role of emtu in mucosae remodeling: Focus on a new model to study chronic inflammatory lung diseases
2020
In recent years, part of the scientific community has focused its attention on the involvement of the epithelial-mesenchymal trophic unit (EMTU) in mucosa remodeling, monitoring its role in chronic inflammatory lung diseases. The term EMTU is used to describe the anatomic and functional relationship between the attenuated fibroblast sheath and epithelial tissue, i.e. the signaling between epithelial cells and the underlying fibroblasts, which are in close indirect physical contact with the former. These interactions are important for many airway functions, such as differentiation during lung growth, repair of damaged tissue and regulation of inflammatory response. Several studies have indic…
Erythrina viarum Tod. (Leguminosae) from the Palermo Botanical Garden
2011
The type of Erythrina viarum Tod. (Leguminosae) is designated and the relationship between this and other species of Erythrina Sect. Caffrae Codd is investigated. The correct name of E. viarum is E. caffra Thunb.
Fregi classici in miniatura: il Partenone e il tempio di Bassae di John Henning
2021
La Gipsoteca del Dipartimento Culture e Società dell’Università di Palermo, di recente riallestita, possiede tra i suoi calchi due gessi di grande interesse. Si tratta delle repliche delle versioni miniaturizzate dei fregi del Partenone e del Tempio di Bassae che lo scultore scozzese John Henning realizzò a Londra, nei primi decenni dell’Ottocento. Le riproduzioni furono inizialmente incise su piccole tavole di ardesia, dalle quali potevano essere ricavati calchi in gesso, destinati alla vendita. Ne nacque presto un lucroso commercio di copie non autorizzate, dal quale purtroppo Henning non guadagnò nulla. Tali manufatti, che poche volte hanno attirato l’attenzione degli archeologi, assolve…
A survey of the function of the lethal kettle traps of Arisaema (Araceae), with records of pollinating fungus gnats from Nepal
2000
Abstract Evidence from recent research combined with an evaluation of the literature indicates that Arisaema is adapted to pollination by fungus gnats. It apparently shares this peculiarity among aroids only with the distantly related genus Arisarum . In addition to previous records from Japan and North America, systematic collections from nine Arisaema species during several expeditions in the Himalayas in Nepal showed that, although other less efficient insect groups may participate, the nematoceran families Mycetophilidae and Sciaridae are the principal pollen vectors; they best fit the pollination apparatus of the mainly (para)dioecious kettle trap blossoms. A total of 16 fungus gnat ge…
Mitochondrial Dna Variation in Rhopalosiphum padi (Homoptera: Aphididae) Populations from four Spanish Localities
1992
In total, 35 clones of the bird cherry-oat aphid, Rhopalosiphum padi (L.) established from samples collected in four distant localities of Spain during fall 1989 and spring 1990 were examined for mitochondrial DNA variation using 20 restriction endonucleases. Individual parthenogenetic adults were used to establish clonal lines on wheat (‘Talento’) seedlings. Restriction site polymorphism was detected only with endonuclease Rsa I, but no statistical treatment of data could be done until more polymorphic endonucleases are found. Length variation of the mitochondrial DNA molecule, however, was extensive among R. padi clones. Distribution among populations of this size polymorphism was used to…

Heurs et malheurs d’un tyran: le cas de Hiéron de Syracuse, in Pallas 79, 2009, 81-103
2009
The analysis focuses on the figure of Hieron, a Syracusan tyrant who met with mixed fortune in scholarly studies. Often compared with his brother Gelon, the second of the Deinomenides was seen as a rapacious and violent tyrant. We here reconsider the testimonies on Hieron in order to find out to what extent that judgement actually corresponds to the image which the tradition of Antiquity gave of the tyrant. The case of Hieron offers above all an opportunity to examine the lines which oriented the studies on tyranny in Sicily and to provide an outline of the latest prospects of research. L’analyse se concentre sur la figure de Hiéron, tyran de Syracuse, qui eut une fortune diverse dans les é…
L'ASSURANCE DU RAPPORT DE DURABILITÉ EN ESPAGNE ET AMÉRIQUE LATINE
2015
Este trabajo presenta un estudio sobre el aseguramiento de los informes de sostenibilidad emitidos en España y Latinoamérica. Sobre una muestra de 783 empresas que envían su informe de sostenibilidad al Global Reporting Initiative, se identifican en primer lugar las características corporativas que conducen a las empresas a someter a aseguramiento dicho informe. En segundo lugar, se analiza la evolución del mercado de aseguramiento y su distribución que se evidencia dominado por firmas auditoras. En tercer lugar, se estudia el contenido del informe de aseguramiento para observar las diferentes tendencias en su confección, así como para crear un índice sobre la calidad del mismo. Las conclus…
HSP70 sequestration by free α-globin promotes ineffective erythropoiesis in β-thalassaemia
2014
International audience; β-Thalassaemia major (β-TM) is an inherited haemoglobinopathy caused by a quantitative defect in the synthesis of β-globin chains of haemoglobin, leading to the accumulation of free α-globin chains that form toxic aggregates. Despite extensive knowledge of the molecular defects causing β-TM, little is known of the mechanisms responsible for the ineffective erythropoiesis observed in the condition, which is characterized by accelerated erythroid differentiation, maturation arrest and apoptosis at the polychromatophilic stage. We have previously demonstrated that normal human erythroid maturation requires a transient activation of caspase-3 at the later stages of matur…
