Next-Generation Sequencing-Based RiboMethSeq Protocol for Analysis of tRNA 2'-O-Methylation.
2016
Analysis of RNA modifications by traditional physico-chemical approaches is labor intensive, requires substantial amounts of input material and only allows site-by-site measurements. The recent development of qualitative and quantitative approaches based on next-generation sequencing (NGS) opens new perspectives for the analysis of various cellular RNA species. The Illumina sequencing-based RiboMethSeq protocol was initially developed and successfully applied for mapping of ribosomal RNA (rRNA) 2'-O-methylations. This method also gives excellent results in the quantitative analysis of rRNA modifications in different species and under varying growth condi…
Review of Knowledge Management Models for Implementation within Advanced Product Quality Planning
2014
The purpose of this paper is to review different Knowledge Management Models (KMM) based on their strengths and weaknesses and to ascertain their possible implementation within the scope of the Advanced Product Quality Planning (APQP) procedure. The KMM listed are selected based on an extensive literature review. They are presented in a visual manner and analyzed based on their structure and features, versus a predetermined set of criteria. This study offers an overview and a critical discussion of the merits and faults of a number KMM and suggests possible improvement avenues.
Trends of some high quantiles of average and extremes inter-arrival timesand rainfall depths at daily scale for an Italian Sub-Alpine area
2015
Modeling of rainfall statistical structure represents an important research area in hydrology, meteorology, atmospheric physics and climatology, because of the several theoretical and practical implications. The statistical inference of the alternation of wet periods (WP) and dry periods (DP) in daily rainfall records can be achieved through the modelling of inter-arrival time-series (IT), defined as the succession of times elapsed from a rainy day and the one immediately preceding it. It has been shown previously that the statistical structure of IT can be well described by the 3-parameter Lerch distribution (Lch). In this work, Lch was successfully applied to IT data belonging to a sub-al…
Grapevine pests in Sicily.
2008
More than twenty phytophagous species are reported associated with Sicilian vineyards. Only a quarter of them have to be considered of economic importance. Among moths, the grapevine moth Lobesia botrana (Denis & Schiffermüller) is certainly the most frequent species. It is considered the key pest on both table and wine grapes, while the incidence of the grape berry moth Eupoecilia ambiguella (Hübner) is scarce and linked to particular biotopes. Three to four flights are reported for the grapevine moth from February-March to October-November, while no data are available for the grape berry moth. Damages caused by L. botrana are strictly linked to the climatic trends during the summer period…
La sicurezza dei ciclisti: valutazione dei percorsi ciclabili della città di Palermo
2013
The safety of cyclists: evaluation of cycle paths in the city of Palermo Some Italian cities have developed a growing interest in the development of cycling and they are equipped with efficient network of bicycle paths. Palermo has a high potential for increasing the use of the bicycle, for both orographic characteristics of its urban center both for the highly favorable climatic conditions. Unfortunately, a lack of integration between the urban and the transport system, generated infrastructures in urban areas, which for lack of space does not offer users a high level of service in terms of comfort and safety. These conditions don’t have certainly encouraged the development of an active cy…
Role of Stress History on the Swelling-Shrinkage Behavior of Compacted Scaly Clay
2022
Compacted scaly clays are complex geomaterials widely used for the realization of dam cores and waste dump liners. This research aims to investigate the swelling/shrinkage behavior of these geomaterials subjected in an oedometric cell to complex hydromechanical stress paths, including different sequences of cyclic variations of suction and stress. Microstructure investigations, based on scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) techniques, highlighted the microstructural characteristics of the material, which are the distinctive microfabric features (particles assemblages and scales) and the double-porosity networks, where micro- and macropores coexist. More…
Presentazione
2013
Il testo propone un articolato commento alle posizioni teoriche e alle linee di ricerca progettuale espresse da Michele Argentino, professore ordinario di Design a Palermo circa la necessità di riconquistare il ruolo sociale alla creatività individuale, riprendendosi il desiderio di diventare nuovamente "Homo Faber". Il testo inoltre presenta gli obiettivi della nuova collana scientifica - diretta dall'autrice - dal Titolo " Design e Contesti": intercettare ambiti di ricerca trasversali alle discipline del progetto, favorire gli intrecci tra idee progettuali e percorsi di innovazione socio-culturale, sviluppare nuove strategie produttive compatibili con i diversi aspetti della sostenibilità.
La Kasbah organizzata
2013
A partire dai '50 gli architetti hanno prestato attenzione alla kasbah delle città islamiche. Alcuni edifici molto recenti danno prova che questo interesse è tutt'altro che esaurito. Il museo a Leon di Mansila & Tunón così come alcuni edifici della Sejima e di OMA sono in realtà ulteriori esercizi sul tema – legato alla kasbah - affrontato dall'Ospedale di Venezia di Le Corbusier e dall'Unità di abitazione orizzontale di Libera e i progetti e gli edifici del Team X. Sin dalle prime fasi del Movimento Moderno la kasbah costituì una presenza scomoda. L'ortodossia razionale del MM non poteva sposare principi quali la crescita per duplicazione di cellule, lo sviluppo orizzontale, le relazione c…
Una pioggia vitale
2021
Pioggia di Libri è una manifestazione promossa da Andrea Sciascia, nell’ambito delle attività didattiche e scientifiche del Dipartimento di Architettura che ha lo scopo di divulgare ed incentivare il rapporto tra gli studenti ed il mondo accademico. Con il presente contributo, l’autore (da delegato alla Didattica per il Dipartimento di Architettura) evidenzia alcune importanti ricadute dirette di questa iniziativa sul piano formativo per gli studenti. Rain of Books is an event promoted by Andrea Sciascia, as part of the educational and scientific activities of the Department of Architecture which aims to disseminate and encourage the relationship between students and the academic world.

Economical aspects, toxicity, and environmental fate of cerium oxide
2020
Abstract The present chapter reports some economical aspects of the cerium oxide market. Porter’s and PESTEL analyses have been used to evidence the strengths and weaknesses of the ceria market, along with the potentiality and opportunities within the years to come. The wide use of CeO2 nanoparticles in many applications requires to consider also issues related to their toxicity and environmental fate. In this regard, some contradictory reports in the relevant literature have been surveyed, thus highlighting the need for further and detailed investigation on these topics in order to propose effective strategies of risk assessment and environmental remediation.
