Back (and forth) to the future. E.Journal [on line], 9(9), 185-193.
2012
Progetti di città del futuro nel passato e ipotesi di possibilità di vita su Marte. Si fa cenno alle due principali emergenze naturali di Marte, il Mons Olympus e le Valles Marineris. Nella trattazione, a proposito delle questioni connesse con la eventuale terraformazionedel pianeta, l’autrice introduce la necessità di considerare tali emergenze quali elementi da sottoporre a salvaguardia. È chiaro che un processo di terraformazione, per quanto arduo, una volta che superasse le difficoltà maggiori, che sono quelle dell’avvio, del primo mantenimento e della complessiva indirizzabilità, non potrebbe evitare di coinvolgere questi e altri siti che, tuttavia, già adesso e nella prospettiva di un…
Multi-experimental study of micro-structural and mechanical consequences of thermal cycles applied to a martensitic stainless steel « APX4 »
2010
The Direction des Applications Militaires at the Commissariat à l’Énergie Atomique, a French government-funded technological research organisation, selected a low carbon chromium rich martensitic stainless steel (APX4) to manufacture components with high yield strength and ultimate tensile strength. As such, this thesis is developed around three main axes. Firstly, the thesis summarizes the existing bibliography on this steel as well as its neighboring nuances. Secondly, it engages in a precise characterization of the material that is currently used for industrial manufacturing. Finally, this highly experimental work undertakes to observe and interpret the micro-structural and mechanical co…
Update of the distribution and habitat use of the wildcat, pine marten and weasel in Sicily
2020
The wildcat (Felis silvestris), the pine marten (Martes martes) and the weasel (Mustela nivalis) are key members of the mammalian community in Sicily, actually performing the role of top predators and consequently influencing the trophic chain both in natural and agricultural areas. However, despite their protected status, very little information is available regarding their occurrence and ecology. Here, by verifying published studies, collecting personal observations and analyzing novel field data obtained by camera traps, we update their spatial distribution in Sicily, contributing to a better understanding of their habitat use and suggesting future research to improve our knowledge of th…

An MDE Approach for Rapid Prototyping and Implementation of Dynamic Reconfigurable Systems
2015
This article presents a co-design methodology based on RecoMARTE, an extension to the well-known UML MARTE profile, which is used for the specification and automatic generation of Dynamic and Partially Reconfigurable Systems-on-Chip (DRSoC). This endeavor is part of a larger framework in which Model-Driven Engineering (MDE) techniques are extensively used for modeling and via model transformations, generating executable models, which are exploited by implementation tools to create reconfigurable systems. More specifically, the methodological aspects presented in this article are concerned with expediting the conception and implementation of the hardware platform and the integration of corre…
Caunu (Martes spp.) barošanās paradumu un citu faktoru ietekme uz helmintofaunu un to raksturojošajiem parametriem Latvijā un Lietuvā
2016
Caunas ir savvaļas rezervuāri zoonotiskām un veterināri nozīmīgām parazītu sugām, barošanās paradumu izpēte sniedz informāciju par iespējamiem parazītu invadēšanās ceļiem. Materiāli pētījumam ievākti Latvijas un Lietuvas reģionos laikaposmā no oktobra līdz aprīlim. Lai veiktu barības analīzi, izmeklēti 144 caunu kuņģi. Konstatētie barības objekti iedalīti 14 lielās kategorijās, zīdītāju taksoni noteikti pēc akotmatu struktūras. Kursa darba ietvaros 150 caunas helmintofaunas noteikšanai izmeklētas ar Skrjabina pilnās helmintoloģiskās sekcijas metodi. Meža caunas galvenie barības objekti pēc patērētās biomasas ir grauzēji (37,6%), putni (29,3%) un augi (17,7%) un attiecīgi sastāda arī lielāko…
Vienšūnas parazīta Toxoplasma gondii ekstensitāte meža caunas (Martes martes) un akmeņu caunas (Martes foina) populācijās Latvijas un Lietuvas terito…
2015
Vienšūnas parazītam Toxoplasma gondii par starpsaimnieku var kļūt jebkuras siltasiņu dzīvnieku sugas pārstāvis - arī meža un akmeņu caunas. Laikā no 2011.gada līdz 2014.gadam Latvijas un Lietuvas teritorijā tika ievākti 186 meža un akmeņu caunu muskulatūras paraugi, lai noteiktu T. gondii izplatību, sastopamību un to ietekmējošos faktorus. Kopējā konstatētā T. gondii invāzijas ekstensitāte caunās ir 65,1%. Būtiski augstāka T. gondii ekstensitāte konstatēta meža caunās (67,8%), salīdzinot ar akmeņu caunās konstatēto (52,9%). Būtiskākais T. gondii ekstensitāti ietekmējošais faktors ir dzīvnieka svars. Meža caunām būtiski augstāka T. gondii invāzijas ekstensitāte (69,8%) tika novērota skujkoku…
Valutazione dell’alterazione con laser scanner negli ammassi a struttura orientata e nella diagnostica dei beni monumentali
2011
The applications of laser technology in the field of Rock Mechanics are at a stage of development that allow a reliable use for the reliefs of the mesostructure and for the morphological reconstruction of monuments in place of traditional techniques such as, for example, photogrammetry. The most recent research suggests that the laser may also allow assessment of characteristics such as roughness, which is known to affect the shear strength of discontinuities. Assessing the ratio between the energy of the reflected ray and the one emitted by the instrument, called "reflectivity (I)", it seems possible, also get information on the status of surface discontinuities or areas of historic monume…
