Quel "mezzo pollice" di materia
2012
Il capitolo contiene una riflessione sul ruolo delle superfici architettoniche nei monumenti e nei contesti antichi. Nel tentativo di tracciare l'evoluzione del concetto di restauro fino all'indirizzo attuale, il contributo richiama, tra gli altri, il pensiero di John Ruskin e Alois Riegl, che hanno evidenziato il valore di autenticità e rimarcato il ruolo delle superfici nella percezione dell'architettura storica, contestando i restauri distruttivi in corso in molte città (come il restauro della Basilica di San Marco a Venezia). This chapter includes a reflection on the role of architectural surfaces in monuments and ancient contexts. In attempt to trace the evolution of the concept of res…
Setting up of a protocol of environmental research for preservation and right exploitation of the cultural heritage
2007
The research aims at collecting information on the state of preservation of the cultural heritage in Palermo, and deals more precisely with Vittorio Emanuele avenue, itself bounded by two city gates called Porta Felice (northern gate facing the Mediterranean sea) and Porta Nuova (southern gate) that both give access to the historic centre of the city. Another important purpose is the assessment of livability level, be it for workers, residents, cultural operators, or else visitors, with a particular interest in traffic noise. The research has been conducted by means of miscellaneous scientific duties; however we shall only refer here to two types of practice : the monitoring of environmenta…
MICROBIOLOGICAL QUALITY OF SOUS VIDE COOK-CHILL PRESERVED FOOD AT DIFFERENT SHELF LIFE
2010
The effect of three different periods of storage life (0, 15 and 30 days) on the microbiological quality of several foods elaborated with the sous vide cook–chill procedure in a restaurant was studied. These foods are grouped in three categories: meat (breast chicken, foie gras, pork loin and entrecote of veal), fish (codfish, gilt head sea bream, hake and salmon) and vegetable (broccoli, courgette, potato and carrot). Total plate counts in the products studied were in the range of <1.00–3.74 log10 cfu/g. Coagulase negative staphylococci were isolated in the three categories, Enterococcus spp. were isolated from foie gras and Pantoea agglomerans from salmon and carrot. Staphylococcus aureus…

Simple techniques suitable for long-term storage of Plasmopara viticola
2006
Summary. Propagules of Plasmopara viticola or fragments of P. viticola infected host tissue were stored by three techniques, freezing at –25°C, dehydration with CaCl2, and freeze-drying. Viability tests were performed periodically until exhaustion of the testing sample. P. viticola samples that were frozen at -25°C remained viable for eight years, whereas the CaCl2 dehydrated samples remained viable for eight and a half years. Freeze-drying was the most successful long-term storage method, being able to preserve samples for almost 21 years.
Conservation of forest biodiversity in Sicily: contribution of the University of Palermo Germplasm Bank (Italy)
2017
Germplasm Banks dedicated to the wild plants seeds conservation play a unique role in integrating the in situ conservation of endemic, rare or endangered plant species. One of the missions of the Seed Bank of the University of Palermo (HBP-Bank) is to support the conservation of biodiversity with particular attention to the spectrum of genetic diversity of plants belonging to Mediterranean habitat. Abies nebrodensis (Lojac.) Mattei is an relict species, consisted of 30 natural individuals, gathered in a small area of the Madonie Natural Park in Sicily (1500 -1600 m above s.l.), recorded on the checklist “TOP 50 Mediterranean Island Plants”. It is also one of eight conifers species criticall…

Wooden churches in Lithuania : analysis of failures and degradations, guidelines for restoration
2016
La maggior parte degli edifici di culto in legno lituani versa in una penosa condizione di degrado, poiché le comunità locali non sempre rivolgono la dovuta attenzione ai fenomeni di dissesto e degrado e spesso le competenze tecniche capaci di salvaguardare tale patrimonio sono andate perdute. Le cause più frequenti di questo stato di fatto derivano da una inadeguata manutenzione (sia ordinaria che straordinaria), dal deterioramento del legno (ascrivibile per lo più ad infestazioni di funghi e insetti) o da dissesti e stati deformativi delle strutture dovuti ad errori nella tecnica costruttiva o all’errato dimensionamento delle sezioni costitutive degli elementi di base delle singole unità …
