IDENTIFICATION OF BACTERIAL TAXA IN ARCHAEOLOGICAL WATERLOGGED WOOD
2014
Summary The microscopic and molecular techniques described in this study are aimed at understanding the degradation processes of the anatomical structure of submerged archaeological wood, correlating it to the degradation induced by bacteria. The SEM micrographs showed alterations of the wooden structure due to bacterial colonization, as well as the presence of pyrite framboids. The difficulty of extracting bacterial DNA from wooden fragments belonging to submerged finds is well-known, due to the presence of many inhibitors; this study describes some extraction and in vitro amplification protocols for wooden submerged finds. The results of the molecular investigations, based on the analysis…
Techniki kształcenia słuchania w L1. Perspektywa lingwo- i glottodydaktyczna
2022
Celem niniejszego artykułu jest przedstawienie i omówienie wybranych technik, za pomocą których można z powodzeniem kształcić umiejętność słuchania na lekcjach L1. Autorka jako pierwsze omawia techniki, o których w latach 90. pisali lingwodydaktycy – Tadeusz Patrzałek i Maria Nagajowa, następnie prezentuje wybrane techniki glottodydaktyczne, które, po ich dostosowaniu do specyfiki słuchania w L1, można wykorzystać na lekcjach języka polskiego jako ojczystego. Autorka wychodzi z założenia, że integracja koncepcji lingwo- i glottodydaktycznych może przyczynić się do skutecznego i świadomego kształcenia umiejętności słuchania na lekcjach języka polskiego jako ojczystego.
Taktisko paņēmienu izmantošana un ar to sistītas problēmas pratināšanā
2015
Kriminālprocesa likuma 10.nodaļā ir nosaukti izmeklēšanas darbību veidi un to būtība. Viena no šīm izmeklēšanas darbībām ir pratināšana, tās definīcija ir noteikta Kriminālprocesa likuma 145.pantā. Kriminālprocesa likums nesniedz priekšstatu par pratināšanas nozīmīgumu un pratināšanas norises kārtību. Tas ir atrodams kriminālistikas un kriminālprocesa literatūrā un doktrīnā. Pašu pratināšanas kārtību un tās norisi nosaka procesa virzītājs. Lai efektīvi spētu izmantot pratināšanai paredzēto laiku un noskaidrotu no pratināmās personas patiesu informāciju, procesa virzītājam ir jāizmanto taktiskie paņēmieni, ar mērķi padarīt pratināmās personas vēlmi sniegt nepatiesas ziņas par neiespējamu.

Non-stationary dynamo and magnetospheric accretion processes of the classical T Tauri star V2129 Oph
2011
We report here the first results of a multiwavelength campaign focussing on magnetospheric accretion processes of the classical T Tauri star V2129 Oph. In this paper, we present spectropolarimetric observations collected in 2009 July with ESPaDOnS at the Canada-France-Hawaii Telescope and contemporaneous photometry secured with the SMARTS facility. Circularly polarized Zeeman signatures are clearly detected, both in photospheric absorption and accretion-powered emission lines, from time-series of which we reconstruct new maps of the magnetic field, photospheric brightness and accretion-powered emission at the surface of V2129 Oph using our newest tomographic imaging tool - to be compared wi…
Chandra study of the eclipsing M dwarf binary, YY Gem
2012
The eclipsing M dwarf binary system, YY Gem, was observed using Chandra covering 140 ks (2Prot) in total, split into two even exposures separated by 0.76 d (0.94 Prot). The system was extremely active: three energetic flares were observed over the course of these observations. The flaring and non-flaring states of the system are analysed in this paper. The activity level increased between the first and second observations even during the quiescent (non-flaring) phases. An analysis of the dynamics of the X-ray-emitting plasma suggests that both components are significantly active. Contemporaneous Hα spectra also suggest that both components show similar levels of activity. The primary star i…
L'utilizzo del ferro a Palermo dopo il terremoto del 1726
2016
La ricerca, basata essenzialmente sullo studio di una consistente mole di documenti emersi attraverso nuove indagini archivistiche, mira a indagare gli aspetti tecnici legati agli interventi sul patrimonio architettonico di Palermo successivi al terremoto del 1726, approfondendo il ruolo degli architetti e dei maestri coinvolti nel processo di ricostruzione delle fabbriche colpite e ponendo particolare attenzione alle tecnologie messe in atto facenti ricorso all’uso ferro, indagate attraverso lo studio di alcuni casi esemplificativi. Questo materiale, infatti, trovò in questa occasione diverse applicazioni. L’intervento più frequente fu relativo all’inserimento di catene in ferro in corrisp…

Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
Institute of the Holy Heart in Palermo. Architectural and technological proposal of rehabilitation intervention for post-pandemic social housing.
2021
Close to the historical city centre, the prince Pignatelli built his villa-palace in the 18th century. Later it became the headquarter of the Order of the Holy Heart that instituted a school attended by the highest society. The 11430 m2 historical building (ground floor, first and second floor), along with its monumental garden (about 9600 m2), was abandoned by the nuns in 2008. The novel ownership is aimed at restoring and re-functionalising the complex, a kaleidoscope of urban-architectural and technological stratifications, located in a crucial point of Palermo still waiting for a new season of requalification, being also close to the Zisa castle, included in the UNESCO Arab and Norman i…
Positive solutions for nonlinear Robin problems
2017
We consider a parametric Robin problem driven by the p-Laplacian with an indefinite potential and with a superlinear reaction term which does not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions. We prove a bifurcation-type theorem describing the nonexistence, existence and multiplicity of positive solutions as the parameter varies. We also show the existence of a minimal positive solution $\tilde{u}_\lambda$ and establish the monotonicity and continuity of the map $\lambda\to \tilde{u}_\lambda$.
