Membrane distillation: Solar and waste heat driven demonstration plants for desalination
2013
Abstract The development of small to medium size, autonomous and robust desalination units is needed to establish an independent water supply in remote areas. This is the motivation for research on alternative desalination processes. Membrane distillation (MD) seems to meet the specific requirements very well. This work is focused on experimental studies on full scale demonstration systems, utilizing a parallel multi MD-module setup. Three different plant concepts are introduced, one of them is waste heat driven and two of them are powered by solar thermal collectors. Design parameters and system design are presented. After the analysis of plant operation a comparison among the plants as we…
Degradation of long-chain n-alkanes in soil microcosms by two actinobacteria
2012
The ability of two recently isolated actinobacteria, that degrade medium and long chain n-alkanes in laboratory water medium, was investigated in soil microcosms using different standard soils that were artificially contaminated with n-alkanes of different length (C(12)- C(20)- C(24)- C(30)). The two strains, identified as Nocardia sp. SoB and Gordonia sp. SoCp, revealed a similar high HC degradation efficiency with an average of 75% alkane degraded after 28 days incubation. A selectivity of bacteria towards n-alkanes of different length was detected as well as a consistent effect of soil texture and other soil physical chemical characteristics on degradation. It was demonstrated the specif…

Nuove, condensate riflessioni sull’apporto della comparazione alla scienza giuridica
2020
Il lavoro prende spunto da un memorabile Convegno svoltosi a Torino nel 1979 durante i lavori dell’Associazione Italiana di Diritto Comparato (AIDC) e dai fondamentali apporti forniti, tra gli altri, da Gino Gorla e Rodolfo Sacco, per ripercorrere la strada che la comparazione giuridica ha compiuto nel corso degli ultimi decenni del secolo scorso per affermare in modo stabile ed incontroverso la peculiarità del proprio metodo scientifico e la sua capacità di portare benefici alla scienza giuridica nel suo complesso. Nel corso della presente ricerca si descrivono le premesse storiche che, a partire dal fondamentale scritto di Emerico Amari del 1857, hanno collocato il diritto comparato come …
Exploring long chain n-alkane metabolism in Gordonia sp. strain SoCg
2009
Many microorganisms are able to degrade aliphatic hydrocarbons and a relationship between n-alkane utilization and storage compound synthesis has been described in bacteria. The Gram positive GC-rich n-alkane degrader Gordonia sp. strain SoCg, isolated from a long-term accidentally contaminated beach in Sicily, is able to grow on long n-alkanes up to. It carries a single copy of the alkane hydroxylase gene alkB on its chromosome and its alk cluster revealed a genomic organization similar to other alk clusters of alkane-degrading Gram positive bacteria. The alk gene expression, analysed by Real-time RT-PCR, is induced by n-hexadecane and n-triacontane and coupled to alkane consumption. Inter…
La fortuna del capitello ionico nella Gortina imperiale: i modelli microasiatici e le rielaborazioni in marmo grigio locale
2020
Le indagini archeologiche nella città di Gortina hanno riportato in luce alcuni capitelli ionici di modello microasiatico in marmo importato, databili alla seconda metà del II sec. d.C., ma anche un gran numero di capitelli ionici in marmo grigio locale, con ogni evidenza prodotti in loco tra la fine del II e gli inizi del III sec. d.C. Si tratta di membrature riutilizzate in edifici più tardi e spesso reimpiegate come materiale da costruzione o rifunzionalizzate in vari modi. La loro relativa abbondanza, per alcuni versi insolita, testimonia non solo la peculiare fortuna del tipo nella capitale cretese, ma anche la grande attività degli atelier di scalpellini locali, almeno a partire dalla…
Rational normal curves and Hadamard products
2021
AbstractGiven $$r>n$$ r > n general hyperplanes in $$\mathbb P^n,$$ P n , a star configuration of points is the set of all the n-wise intersection of the hyperplanes. We introduce contact star configurations, which are star configurations where all the hyperplanes are osculating to the same rational normal curve. In this paper, we find a relation between this construction and Hadamard products of linear varieties. Moreover, we study the union of contact star configurations on a same conic in $$\mathbb P^2$$ P 2 , we prove that the union of two contact star configurations has a special h-vector and, in some cases, this is a complete intersection.
La collezione di Anatomia Patologica dell'Università di Palermo: storia e consistenza al 1859.
2012
This paper outlines the history of the Cabinet of Pathological Anathomy at the University of Palermo, describes rapidly its current status and analyzes the composition of its displays in 1859. It aims to highlight the analogies with other collections of a similar kind and to pinpoint potential actions to endorse and develop this important scientific asset.
