Pittura del XIX e del XX secolo nel segno del collezionismo siciliano
2020
Il volume offre una ricognizione sul collezionismo in Sicilia e prende in esame, per la prima volta nella sua interezza, una collezione privata proponendo la riscoperta di opere di autori rappresentativi della cultura figurativa italiana del XIX e del XX secolo, tra cui Michele Catti, Ettore De Maria Bergler, Onofrio Tomaselli, Pippo Rizzo, Alfonso Amorelli e Pina Calì. La collezione privilegia la pittura dell’isola ma include anche il pittore non siciliano Giuseppe Amisani e la coppia di bronzi di Antonio Ugo e trova nelle opere "Costumi" di Salvatore Lo Forte del 1839 e "Sogno del carabiniere" di Pippo Rizzo degli anni ’50 i propri limiti cronologici. Questa raccolta privata, per lo più i…
Scientific studies for the restoration of a wood painting of the Galleria Interdisciplinare Regionale della Sicilia—Palazzo Mirto di Palermo
2016
Abstract The Ritratto muliebre, referring to Venus, is a panel painting, oil on wood, attributed to unknown artist and probably dated to the second half of 16th century, today conserved in the Galleria Interdisciplinare Regionale della Sicilia—Palazzo Mirto of Palermo. The aim of this research was to assess the techniques used to decorate the wooden painting and to verify the state of conservation of the artwork's materials but also to identify the previous treatments. This study was the essential condition to plane and perform the correct restoration. For this reason, an integrated analytical approach based on the use of non-invasive and micro-invasive techniques was used, with the aim to …
Il cantiere dell'Arsenale. Materiali e tecniche
2017
Esistono architetture le cui travagliate vicissitudini, se comprese in rapporto con la storia della città cui appartengono, finiscono per far assumere, alle stesse architetture, un ruolo emblematico e simbolico. Palermo, come e più di ogni altra città, si è alimentata per millenni di simboli spesso antitetici. La sua principale attitudine sembra essere stata, nel corso di una lunga storia edificatrice, una disseminazione di architetture o di fatti urbani in cui rispecchiarsi, quali vere e proprie sineddoche, parti rappresentative del tutto. Sembrerebbe quasi che Palermo ritragga se stessa, con le sue molteplici contraddizioni, in molte delle architetture che più la rappresentano e ne riprod…

Circulating miRNAs in Successful and Unsuccessful Aging. A Mini-review
2019
Aging is a multifactorial process that affects the organisms at genetic, molecular and cellular levels. This process modifies several tissues with a negative impact on cells physiology, tissues and organs functionality, altering their regeneration capacity. The chronic low-grade inflammation typical of aging, defined as inflammaging, is a common biological factor responsible for the decline and beginning of the disease in age. A murine parabiosis model that combines the vascular system of old and young animals, suggests that soluble factors released by young individuals may improve the regenerative potential of old tissue. Therefore, circulating factors have a key role in the induction of …
Sakarība starp PTH un IGFBP-1 līmeņiem un to ietekme uz gados vecāku sieviešu mirstību 10 gadu prospektīvā pēcpārbaudes pētījumā

KOPSAVILKUMS Atslēgas vārdi: Paratiroīdais hormons, Insulīnam Līdzīgā Augšanas Faktora Saistošais Proteīns-1, Kardiovaskulārās Slimības, Mirstība. Ievads: Šī pētījuma mērķis bija definēt un pētīt tiešu un netiešu mijiedarbību starp faktoriem, kas ietekmē kalcija homeostāzes sistēmu un metabolā sindroma attīstību. Mēs analizējām iespējamās korelācijas starp PTH un IGFBP-1 un dažiem metabolā sindroma marķieriem, tad pielietojām Koksa regresijas analīzi, lai izpētīt kopējo PTH un IGFBP-1 ietekmi uz mirstību kardiovaskulāro slimību dēļ, kuriem ir zināma saikne ar metabolo sindromu. Materiāli un metodes: Šis ir longitudināls, uz populāciju balstīts prospektīvs kohortas pētījums ar 10 gadu ilgu p…
Experimental study of the triple-gluon vertex
1991
Abstract In four-jet events from e+e− →Z0 →multihadrons one can separate the three principal contributions from the triple-gluon vertex, double gluon-bremsstrahlung and the secondary quark-antiquark production, using the shape of the two-dimensional angular distributions in the generalized Nachtmann-Reiter angle θ NR ∗ and the opening angle of the secondary jets. Thus one can identify directly the contribution from the triple-gluon vertex without comparison with a specific non-QCD model. Applying this new method to events taken with the DELPHI-detector we get for the ratio of the colour factor Nc to the fermionic Casimir operator C F : N c C F = 2.55 ± 0.55 ( stat. ) ± 0.4 ( fragm. + models…

The role ofSphagnummosses in the methane cycling of a boreal mire
2010
Peatlands are a major natural source of atmospheric methane (CH4). Emissions from Sphagnum-dominated mires are lower than those measured from other mire types. This observation may partly be due to methanotrophic (i.e., methane-consuming) bacteria associated with Sphagnum. Twenty-three of the 41 Sphagnum species in Finland can be found in the peatland at Lakkasuo. To better understand the Sphagnum-methanotroph system, we tested the following hypotheses: (1) all these Sphagnum species support methanotrophic bacteria; (2) water level is the key environmental determinant for differences in methanotrophy across habitats; (3) under dry conditions, Sphagnum species will not host methanotrophic ba…
Stable carbon isotopic composition of peat columns, subsoil and vegetation on natural and forestry-drained boreal peatlands.
2018
We studied natural and forestry-drained peatlands to examine the effect of over 34 years lowered water table on the δ13C values of vegetation, bulk peat and subsoil. In the seven studied sites, δ13C in the basal peat layer was 1.1 and 1.2 ‰ lower than that of the middle-layer and surface layer, respectively. Furthermore, there was a positive correlation between the δ13C values of the basal and surface peat layers, possibly due to carbon (C) recycling within the peat column. In the same mire complex, natural fen peat δ13C values were lower than those of the nearby bog, possibly due to the dominance of vascular plants on fen and the generally larger share of recycled C in the fens than in the…
