Species richness of polypores can be increased by supplementing dead wood resource into a boreal forest landscape
2019
1. To prevent local species extinction and to counteract population declines, we must ensure species have access to resources they require for life. This can be done through ecological restoration where previously depleted resources are reintroduced. If the restoration is conducted as a one-off action in a large area, it resembles a natural resource pulse, which should lead to increased abundance of individuals, accompanied possibly by increased species richness. Species–energy relationship and underlying theory enable predictions about how different features of resource pulses affect species richness. 2. We conducted a large-scale, controlled, randomized and replicated field experiment to …

Audience involvement in creative media for development: Making sense of the semiotic interface
2017
This article explores the role that semiotic communication plays in the generation of narrative affect. It also draws on Suruchi Sood’s concept of audience involvement as being capable of increasing self-efficacy and collective-efficacy, both of which are crucial to behaviour change. It therefore, demonstrates how semiotic tropes are used in creative media narratives to elicit affect and in turn generate authentic audience involvement with the subjects of those narratives, a process which eventually has positive consequences for behaviour change communication. Hence, these narratives fueled by semiotics, become the threshing floor where potential audiences are drawn into pro-social discours…
Hygrothermal conditions in Cross Laminated Timber (CLT) dwellings
2020
The use of CLT has been increasing the last decade, and a subsequently focus on documentation of the accompanying indoor climate and exposed wooden surfaces on human well-being. This study presents the results of a measurement campaign conducted over one year of a CLT apartment building in Grimstad, Norway. The apartment building consists of three floors with 35 apartments and comply with the Norwegian passive house standard and energy grade A. Measurements of the relative humidity (RH), indoor air temperature and wood moisture content (MC) were performed in the exposed CLT spruce panels in three apartments in two different floors. The results from the three apartments show a relatively sma…
Numerical Investigation of a Wood-Chip Downdraft Gasifier
2019
Biomass gasification is regarded as one of the most promising technology in the renewable energy field. The outcome of such operation, i.e. the synfuel, can be exploited in several ways, for example powering engines and turbines, and is considered more flexible than the biomass itself. For this reason, a careful analysis of the gasification performance is of paramount importance for the optimization of the process. One of the techniques that can be used for such a purpose, is the numerical analysis. CFD is indeed a tool that can be of great help in the design and study of the operation of the gasifier, allowing for an accurate prediction of the operating parameters. In this work, a downdraf…
The International Monetary System in the Context of the Actual Financial Crisis. Change Proposals
2013
The International Monetary System (I.M.S.) has a crucial role in economy, representing the frame for a sustainable development of the economic relationships between states, while contributing at the progress of the world’s economies. Nowadays, this system confronts large difficulties, as a consequence of the lack of financial disciplinary instruments, meant at regulation and coordination. The actual economic-financial crisis proved the limits of the present I.M.S., reason why it is now under “reconstruction”. In this direction, there is a series of reforms that can be implemented, so that the new architecture of the system is much more solid.
Il codice Pontecorvo
2016
Gli ultimi lavori di Pontecorvo, dopo il congedo dal cinema pensato per il grande schermo avvenuto con Ogro. Una serie di documentari, perlopiù regie collettive dal taglio politico e militante, con l’eccezione del cortometraggio Nostalgia di protezione. Il successo di Un altro mondo è possibile, il film sul G8 di Genova del 2001. L’addio definitivo, e il simbolico passaggio del testimone con suo figlio Marco. Esiste un “lascito” cinematografico del regista? L’influenza sul cinema americano contemporaneo, dalla New Hollywood in poi, e qualche equivoco. Alcuni possibili “eredi”, in Italia e all’estero.
Optimizing the Shape of Welded Constructions Made through the Technique “Temper Bead Welding”
2020
Welded constructions are subject to high stresses during operation. One solution for improving the behavior in exploitation of welded constructions in various cases is to use the welding technique “temper bead welding” (TBW). In the paper, the optimization of the geometry of the welded joints by the TBW technique was performed. Thus, corner welded joints made of S355 steel were analyzed. To make the welded joints, three layers of welding seams were deposited, and the intermediate layers were processed through cutting with various radii. To analyze the influence of the size of these rays on the behavior of welded constructions, a research program based on factorial experiences wa…
