Do testate amoebae communities recover in concordance with vegetation after restoration of drained peatlands?

2016

The environmental importance of peatlands has stimulated efforts to restore their specific ecosystem structure and functions. Monitoring and assessment of the ecological state of the peatland is fundamental in restoration programmes. Most studies have focused on the responses of vegetation and, to a lesser extent, on testate amoebae (TA). To our knowledge, none have investigated whether these two groups show concordance in the context of restoration of drained peatland. Here we assess community concordance between TA and vegetation in boreal peatlands belonging to four different land use management classes (natural, drained, restored 3–7 years ago, and restored 9–12 years ago). TA and veget…

Traction test of temporary dental cements

2017

Background Classic self-curing temporary cements obstruct the translucence of provisional restorations. New dual-cure esthetic temporary cements need investigation and comparison with classic cements to ensure that they are equally retentive and provide adequate translucence. The objective is to analyze by means of traction testing in a in vitro study the retention of five temporary cements. Material and methods Ten molars were prepared and ten provisional resin restorations were fabricated using CAD-CAM technology (n=10). Five temporary cements were selected: self-curing temporary cements, Dycal (D), Temp Bond (TB), Temp Bond Non Eugenol (TBNE); dual-curing esthetic cements Temp Bond Clear…

Misfit evaluation of dental implant-supported metal frameworks manufactured with different techniques: Photoelastic and strain gauge measurements

2016

This study aims to compare in-vitro the fitting accuracy of implant-supported metal frameworks used for full-arch orthodontic restoration. The hypotheses tested were as follows: (1) for a fixed implant morphology, strains developed within the framework depend on how the framework had been fabricated and (2) stresses transferred to the implant–bone interface are related to the amount of framework misfit. Metal frameworks were fabricated using four different manufacturing techniques: conventional lost-wax casting, resin cement luting, electrospark erosion, and computer-aided design/computer-aided manufacturing milling. Each framework was instrumented with three strain gauges to measure strai…

Ecology, fisheries and management of wild brown trout populations in boreal inland waters

2010

Eutrophication of aquatic ecosystems is an increasing problem, especially threatening small and shallow freshwater lakes. While the extreme inputs of nutrients (phosphorus and nitrogen) can nowadays be reduced and controlled rather efficiently, additional measures to reverse eutrophication may be needed. These often involve biomanipulation, typically mass removal of cyprinid fish. However, the success of biomanipulations has many times been limited or short lived. The reasons for this are not well known, perhaps because the more subtle impacts of biomanipulation on the ecosystem-wide processes of lakes have not been thoroughly studied. Natural abundance stable isotopes may provide a cost-ef…

Dipinto su tavola “Tre Sante Martiri”: il restauro conservativo di un supporto ligneo gravemente danneggiato

2020

Il poster descrive l'intervento conservativo svolto su un dipinto su tavola raffigurante “Tre Sante Martiri”, secondo il consolidato principio di un approccio multidisciplinare tecnico e scientifico. Il manufatto, realizzato con la tecnica ad olio e risalente al XVII secolo, è di proprietà del Comune di Cefalù (PA), pervenuto a seguito di lascito testamentario da parte di un nobile collezionista dell’Ottocento, l’avvocato Vincenzo Cirincione, ed è conservato presso il locale Museo intitolato ad “Enrico Piraino barone di Mandralisca”. La prima parte dell’intervento ha riguardato lo studio degli aspetti storico-artistici, dei materiali e delle tecniche esecutive, degli interventi pregressi di…

Periodontal Behavior Around Teeth Prepared with Finishing Line for Restoration with Fixed Prostheses. A Systematic Review and Meta-Analysis

2020

Background: The objective of this systematic review and meta-analysis was to analyze the periodontal behavior around teeth prepared with horizontal finishing crowns supporting fixed metal-ceramic and zirconia full coverage crowns and fixed partial dentures (FDPs). Materials and methods: An electronic search was conducted to locate relevant clinical trials in four databases: PubMed, Embase, Cochrane, and Scopus. A manual search was made in the reference sections of the articles identified for any additional articles. No restrictions were applied regarding year of publication or language. The following variables were considered in quantitative and qualitative analysis: probing pocket depth (P…

VALORIZZAZIONE DEL PATRIMONIO Tecnologie, strategie, progetti

2010

The culture is developing, is a capital which can generate income and jobs: from monuments to museums, the landscape, the cultural and creative industries (music, painting, crafts), the culture must be enhanced with all appropriate policies, which concern themselves its preservation and production of the asset value of art. Redeveloping this strategic sector can contribute to our country to achieve a leading position in the global society of knowledge, innovation and creativity. Cultural tourism should be linked to environmental and land. This integration must focus on local realities in terms of recognition and restoration of traditions, cultural heritage, the rediscovery of the natural en…

IL FASCICOLO DEL MONUMENTO COME EFFICACE STRUMENTO DI PREVENZIONE E CURA PROGRAMMATA DEL PATRIMONIO ARCHITETTONICO

2010

The study introduces a search developed in 2008-2009 to set a protocol of study of the monuments to facilitate the action of prevention of the architectural patrimony. The software allows to perform a punctual control of the state of health of the monuments and to act in case of necessity at the right moment. The wise man develops him with an introduction on the condition of the restoration in our time pointing out some distorted aspects in the consideration of the guardianship of the cultural patrimony. The second part is devoted to the brief history of the architectural prevention up to the 1964 Venice Paper. The third part introduces to the actuality of the prevention and the last one he…

Novel qutrit circuit design for multiplexer, De-multiplexer, and decoder

2022

AbstractDesigning conventional circuits present many challenges, including minimizing internal power dissipation. An approach to overcoming this problem is utilizing quantum technology, which has attracted significant attention as an alternative to Nanoscale CMOS technology. The reduction of energy dissipation makes quantum circuits an up-and-coming emerging technology. Ternary logic can potentially diminish the quantum circuit width, which is currently a limitation in quantum technologies. Using qutrit instead of qubit could play an essential role in the future of quantum computing. First, we propose two approaches for quantum ternary decoder circuit in this context. Then, we propose a qua…
