HISTORICAL SCIENTIFIC AND EXPERIMENTAL RESEARCHES AIMED AT FINDING NEW TECHNIQUES AND INSTRUMENTS TO RECOVER

2005

The “building recovery” has been the key point of various talks that, since the ‘60s, have regarded planning and urban landscaping. The reinforced concrete-ruled XXth century has generated buildings that have resulted technologically flawed, if not altogether unattractive. These flaws can be justified by premature use of certain techniques (not will-known the necessity of historical research), but this can not justify the modern degraded townships, the loss of local urban characteristics and the environmental unbalancing. Where sites are of XXth century cultural heritage? Which are the methodologies for documenting and managing? This research is aimed at analysing new techniques and materia…

Restoration and enhancement of KOS City - Greece

2012

Abusiveness phenomenon is an essentially political, social and economi-cal fact in all territories that determines a disadvantage in the community and in its environment. Architectural is “the science of living” and it is called to answer on a problem which is progressively go destroying living places. Architectural must therefore answers to housing needs. Abusiveness is a housing emergency which oppresses towns and citiziens. Architectural does-n’t feel guilty because for too many years architects did something else, cor-rupted building did the rest.

High pressure processing of food-grade emulsion systems: Antimicrobial activity, and effect on the physicochemical properties

2019

Abstract The use of high pressure processing (HPP) for development of stable emulsion-based delivery systems has been recently increased. Under adequate conditions, application of high pressures modifies the functionality of protein and polysaccharide molecules and significantly promotes the emulsifying activities. Application of high pressures also modulates the emulsion microstructure without any destabilization and gelation of protein molecules. The lipid oxidation in HPP-treated emulsions can be accelerated, particularly with higher pressure levels, while the HPP utilization on emulsions in acidic conditions can highly inhibit the growth of spoilage and pathogenic microorganisms. In thi…

Nonlinear beam self-cleaning in a coupled cavity composite laser based on multimode fiber

2017

International audience; We study a coupled cavity laser configuration where a passively Q-switched Nd:YAG microchip laser is combined with an extended cavity, including a doped multimode fiber. For appropriate coupling levels with the extended cavity, we observed that beam self-cleaning was induced in the multimode fiber thanks to nonlinear modal coupling, leading to a quasi-single mode laser output. In the regime of beam self-cleaning, laser pulse duration was reduced from 525 to 225 ps. We also observed a Q-switched mode-locked operation, where spatial self-cleaning was accompanied by far-detuned nonlinear frequency conversion in the active multimode fiber.

Prevenire l’insuccesso scolastico nella scuola secondaria di primo grado: scuola e territorio dialogano

2017

Con il lavoro di co-progettazione per la promozione di una rete integrata tra soggetti pubblici e privati attraverso lo sviluppo di una metodologia di sistema, l’ideazione e realizzazione di strumenti di supporto, è stato offerto un contributo per il contrasto del fenomeno della dispersione scolastica e per la prevenzione del rischio di marginalità sociale negli adolescenti di Palermo. Il progetto ha coinvolto 172 studenti, 171 genitori e 29 docenti di tre scuole secondarie di primo grado, 10 operatori del terzo settore del territorio del Comune di Palermo. Si è partiti dal presupposto che per favorire la dimensione orientativa della scuola media fosse necessario incentivare il dialogo tra …

Etsi, tutki, vertaa, päättele : the development of critical thinking in EFL workbooks

2013

Tämän kandidaatintutkielman tarkoituksena oli selvittää, kehittävätkö alakoulun kuudennen luokan englannin kielen tehtäväkirjojen tehtävät oppilaiden kriittisen ajattelun taitoja. Kriittistä ajattelua on tutkittu lähes sadan vuoden ajan ja ajattelun taitojen opettamisesta on julkaistu erilaisia käsikirjoja. Aiemmat tutkimukset kriittisestä ajattelusta ja oppimisesta ovat kuitenkin koskeneet pääasiassa yliopisto-opiskelijoita ja aikuisia. Kaiken kaikkiaan kriittistä ajattelua kielten oppimisen yhteydessä on tutkittu vähän, vieraiden kielten oppimisen yhteydessä ei juuri lainkaan. Koska aiemmat tutkimukset eivät ole käsitelleet kyseistä aihealuetta, on tutkielma tältä osin edelläkävijä. Tutki…

Retrograde Chronic Total Occlusion Percutaneous Coronary Interventions: Predictors of Procedural Success From the ERCTO Registry

2022

Objectives: The aim of this study was to identify independent predictors of procedural success after retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Background: Retrograde CTO PCI is an established technique, but predictors of success remain poorly understood. Methods: A multivariable logistic regression model was used to analyze potentially important demographic, clinical, anatomical, and technical aspects of retrograde CTO PCI cases uploaded to the multicenter European CTO (ERCTO) Club Registry. Results: In calendar years 2018 and 2019, 2,364 retrograde CTO PCI cases constituted the primary analysis cohort. A primary retrograde strategy was used in 1,953…

The relationship among beliefs about problem solving, epistemological beliefs, grade level, sex, and problem solving achievement: A study in secondar…

2020

The first purpuse of this investigation was to study the effects of sex and grade level on secondary students’ beliefs about epistemology and problem solving. The second purpuse was to analyze the contribution of both belief systems, grade level, and sex to problem solving achievement. One hundred and forty-four High School students, 9th and 11th grade students, took part in the study. Two questionnaires (Schommer and StageKloosterman’s questionnaires) and a problem solving test (two word problems of the PISA tests) were administered to these students. Two ANOVAs, an ANCOVA, and a multiple regression analysis were carried out from data obtained in the investigation. In the light of the fore…

Gradenwitz, Riccobono und die Entwicklung der Interpolationenkritik. Methodentransfer unter europäischen Juristen im späten 19. Jahrhundert / Gradenw…

2018

Die interpolationistische Methode der Untersuchung römischer Rechtstexte, also deren Wahrnehmung als Ergebnis von nachträglichen Eingri4en, ist Gegenstand eines wiedererwachten Interesses der romanistischen Forschung. Ihre intensivste Phase erlebte die Interpolationenforschung am Ende des 19. und in den ersten Jahrzehnten des 20. Jahrhunderts. Das heutige Verstehensinteresse richtet sich insbesondere auf die Verflechtung der interpolationistischen Methode mit anderen Forschungsansätzen sowie auf ihre Entwicklung, die auf dem Gedankenaustausch zwischen Wissenschaftlern in Italien, Deutschland und anderen Ländern basiert. Im Zentrum der hier versammelten Arbeiten stehen Otto Gradenwitz, der B…

Comparison between various bituminous binders modified with crumb tyre rubber

2009

The aim of this paper is to show how the rheology, the performance and the storage stability of different bituminous binders, obtained from two bitumens with different asphaltenes content, change their properties when they are modified with recycled tyre crumb rubber. Physical, chemical and performance characterisation followed by rheological and storage stability analyses have been undertaken as the basis for the comparison. The results of the investigation indicate that bitumen with lower asphaltenes content is more influenced by the modification with the rubber. However, the modification of the bitumen with the higher asphaltenes content gives a binder with better performance and storage…
