Mappe di Lavorabilita’ per Giunti Misti di Alluminio Mediante Processo di Saldatura Linear Friction Welding
2014
Il Linear Friction Welding è un processo di saldatura allo stato solido in cui una parte fissa è forzata contro una parte che si muove con moto lineare alternato per generare calore attraverso l’attrito. Nel presente lavoro viene descritto lo studio effettuato per la realizzazione della giunzione mista mediante processo di Linear Friction Welding tra due leghe di alluminio che presentano proprietà meccaniche differenti, come la lega AA2011 e AA6082. Lo studio è stato condotto analizzando due differenti configurazioni determinate dalla posizione relativa delle leghe costituenti i provini da saldare. Per la realizzazione del processo è stata utilizzata una macchina prototipale dotata di senso…
Il pluralismo giurisdizionale d'età moderna
2021
Il saggio riflette sui concetti di ‘giurisdizione’ e di ‘pluralismo’ sulla base delle più recenti acquisizioni della storiografia italiana sull’età moderna, individuando alcuni percorsi tematici e mostrandone i molteplici profili interpretativi. Tiene conto di taluni ambiti su cui si estende la giurisdizione, ne evidenzia la pervasività e la frammentazione, mostrando come essa sia una chiave di lettura imprescindibile della modernità The essay reflects on the concepts of ‘jurisdiction’ and ‘pluralism’ according to the most recent developments in Italian historiography on the Early Modern Age, identifying some thematic paths and pointing out their multiple interpretative profiles. It conside…
Peat florulas in the Madonie Regional Park (Sicily)
2009
The floristic exploration of the eastern slopes of the Madonie Mountains in Sicily, carried out between 1975 and 1980, resulted in the discovery of several hydromorphic environments characterized by a thick peaty horizon. Locally named “margiu” or “triemula”, depending on the lower or higher depth, they host plant communities characterized by some species of Juncus and Carex together with acidophilous bryophytes including some species of Sphagnum. Their ecology as well as their flora and vegetation have been studied (Petronici et al. 1978). In some localities fossil pollens have also been examined (Bertolani Marchetti et al. 1984). Floristic analyses pointed out some phytogeographical patte…
Microbial succession of nitrate-reducing bacteria in the rhizosphere of Poa alpina across a glacier foreland in the Central Alps
2006
International audience; Changes in community structure and activity of the dissimilatory nitrate-reducing community were investigated across a glacier foreland in the Central Alps to gain insight into the successional pattern of this functional group and the driving environmental factors. Bulk soil and rhizosphere soil of Poa alpina was sampled in five replicates in August during the flowering stage and in September after the first snowfalls along a gradient from 25 to 129 years after deglaciation and at a reference site outside the glacier foreland (> 2000 years deglaciated). In a laboratory-based assay, nitrate reductase activity was determined colorimetrically after 24 h of anaerobic inc…
Consequences of the Digital Economy : Transformation of the Growth Concept
2018
The digital economy is transforming the traditional concepts of economic growth.The recent reversal trend in GDP growth of ICT leaders can be attributed to effective utilization of soft innovation resources in Finland and adherence to traditional resources in Singapore.Confronting a productivity decline in the digital economy, global information and communication technology (ICT) leaders are transforming business models into those with uncaptured GDP creation. This can be attributed tothe harnessing soft innovation resourcesagainst a productivity decline. This in turn activates a self-propagating function and induces supra-functionality beyond economic value corresponding to a shift in peop…
Making conservation sustainable under unfavourable conditions : the case of Chimanimani National Reserve, Mozambique
2019
Based on a case study from the Chimanimani National Reserve in Mozambique, this article analyses to what extent different types of operational practices can contribute to the sustainability of protected areas in relatively unfavourable external conditions. While current conservation policies highlight community participation and market-based approaches, the same “best practices” are not equally valid under different conditions. Where unfavourable natural conditions, lack of infrastructure, difficult access and political instability limit the potential for upmarket ecotourism, actors should focus on community empowerment, diversification of livelihoods, and building joint conservation ideolo…
Procesy globalizacji i zakłócenie systemu międzykulturowego poprzez ekspansję migracyjną w Europie zagrożeniem światowego pokoju
2017
Zjawisko globalizacji jest bodaj najważniejszym procesem stymulującym rozwój świata w wielu jego wymiarach, a gałęzią, która w sposób najbardziej widoczny podlega temu procesowi, jest sfera działalności gospodarczej. Procesy globalizacyjne kształtowały się od wielu pokoleń, będąc wynikiem działalności człowieka na płaszczyźnie handlowej i kulturalnej, a także w rezultacie ekspansji zaborczych ludów i plemion, które na podbijanych terenach zaszczepiały rodzime zdobycze kulturowe i cywilizacyjne. Globalizacja, z jednej strony niosąca ogromny rozwój gospodarczy świata, z drugiej strony stała się stymulatorem takich zjawisk jak migracja, a okresowe fale migracyjne, zwłaszcza te, których fundame…
The shell matrix of the freshwater mussel Unio pictorum (Paleoheterodonta, Unionoida). Involvement of acidic polysaccharides from glycoproteins in na…
2007
13 pages; International audience; Among molluscs, the shell biomineralization process is controlled by a set of extracellular macromolecular components secreted by the calcifying mantle. In spite of several studies, these components are mainly known in bivalves from only few members of pteriomorph groups. In the present case, we investigated the biochemical properties of the aragonitic shell of the freshwater bivalve Unio pictorum (Paleoheterodonta, Unionoida). Analysis of the amino acid composition reveals a high amount of glycine, aspartate and alanine in the acid-soluble extract, whereas the acid-insoluble one is rich in alanine and glycine. Monosaccharidic analysis indicates that the in…
Niemiecka samorządność terytorialna. Bilans pozjednoczeniowego trzydziestolecia przemian ustrojowo-strukturalnych
2020
Local government is one of the most important institutions of a democratic rule of law in Germany. Its position and role was basically shaped immediately after the end of World War II. The purpose of this article is an attempt to present and evaluate the systemic and structural changes that have taken place in German local government within 30 years of the post-unification period. The hypothesis of this study is as follows: The political and structural changes of German local government in the last 30 years have been directed towards making the activities of its bodies and institutions more effective as well as strengthening and deepening democracy, influencing the authorities in power, rat…
Wpływ zasady cross compliance na kształtowanie nowej ekonomiki rolnictwa na przykładzie badań w regionie opolskim
2009
Na nową organizację rolnictwa w przestrzeni europejskiej szczególny wpływ mają zasady zreformowanej WPR: decoupling, cross compliance, modulacja, dyscyplina budżetowa. Centralne miejsce wśród tych zasad odgrywa zasada współzależności, która reguluje wewnętrzną organizację rolnictwa, pozostałe zasady dotyczą w większym stopniu jego relacji z otoczeniem (rynkowym, składowymi przestrzeni wiejskiej). Prezentowane w pracy wyniki badań przeprowadzonych w towarowych gospodarstwach rolnych regionu opolskiego potwierdzają wpływ zasady współzależności na decyzje produkcyjne rolników, które w coraz większym zakresie wynikają z wiedzy o zintegrowanych i precyzyjnych metodach zarządzania warsztatem prod…
