Multidisciplinary integrated field campaign to an acidic Martian Earth analogue with astrobiological interest: Rio Tinto
2011
Recently reported results from latest Mars Orbiters and Rovers missions are transforming our opinion about the red planet. That dry and inhospitable planet reported in the past is becoming a wetter planet with high probabilities of water existence in the past. Nowadays, some results seem to indicate the presence of water beneath the Mars surface. But also mineralogy studies by NASA Opportunity Rover report iron oxides and hydroxides precipitates on Endurance Crater. Sedimentary deposits have been identified at Meridiani Planum. These deposits must have generated in a dune aqueous acidic and oxidizing environment. Similarities appear when we study Rio Tinto, and acidic river under the control…
La metodologia della ricerca in didattica
2021
Il testo descrive le tipologie di ricerca in campo didattico; segnala le aree più rappresentate nel panorama italiano degli ultimi anni e gli ambiti ritenuti prioritari per i prossimi anni; indica una metodologia capace di migliorare la pratica educativa già durante lo svolgimento delle azioni di ricerca; fornisce dei suggerimenti per assicurare la qualità delle ricerche di Didattica indipendentemente dal metodo di indagine adoperato. Le argomentazioni svolte sono animate dalla profonda convinzione che non sia possibile fare ricerca in Didattica senza la collaborazione e il confronto dei ricercatori universitari con gli insegnanti e con gli educatori in generale. The text describes the type…
Sistemi Microparticellari Lipidici con proprietà mucoadesive per il trattamento della Broncopneumopatia Cronica Ostruttiva
The Cirrus Coupled Cloud-Radiation Experiment-II
2016
A cirrus study has been undertaken during the second Cirrus Cloud-Radiation Experiment field campaign based in Prestwick, Scotland. We report on a case study describing the radiation and microphysics measurements and cloud modelling work.
Installazione di un tetto verde multistrato in un tipico ambiente urbano del sud Italia
Il verde pensile è un sistema tecnologico che prevede l’utilizzo della vegetazione come strato superiore della copertura di un edificio, impiegato sia per le sue funzioni ambientali che per le sue caratteristiche estetiche (Cascone, 2019). Infatti, la realizzazione di un tetto verde, oltre al suo intrinseco valore ecologico, consente numerosi vantaggi economici ed ambientali rispetto alle coperture tradizionali (Berardi & Ghaffarianhoseini, 2014). Nel tempo, l’interesse nei confronti dei tetti verdi è sempre più cresciuto, sia per i benefici conseguibili che rispondono a molti degli obiettivi delle diverse politiche nazionali, europee e internazionali per la mitigazione e l’adattamento …
Symbolic threat fosters right-wing authoritarianism only among low authoritarians
2014
In a sample of 95 U.S. undergraduates (49.5% women, Mage = 20.99 years, SD = 3.48), we analyzed the effects of symbolic threat on right-wing authoritarianism (RWA). We used data from an experimental study in which negative political attacks on one's own favorite candidate were considered as symbolic threats. A hierarchic moderated regression showed that, as with societal threat, symbolic threat fostered an increase in RWA only among participants with low initial scores on RWA. This increase did not depend on the persuasive effect of being exposed to negative campaigning. The implications, limitations, and possible developments of the research are discussed. © 2014 Cises.
Context-aware intelligent video analysis for the management of smart buildings
2019
To date, computer vision systems are limited to extract digital data of what the cameras "see". However, the meaning of what they observe could be greatly enhanced by environment and human-skills knowledge.In this work, we propose a new approach to cross-fertilize computer vision with contextual information, based on semantic modelization defined by an expert.This approach extracts the knowledge from images and uses it to perform real-time reasoning according to the contextual information, events of interest and logic rules. The reasoning with image knowledge allows to overcome some problems of computer vision such as occlusion and missed detections and to offer services such as people guid…
Everything matters: Molar microwear texture in goats (Capra aegagrus hircus) fed diets of different abrasiveness
2020
There is an ongoing discourse about whether or not external abrasives influence the microscopic wear in herbivore teeth, including a statement that “dust does not matter”. We submitted the maxillary and mandibular second molar of 28 goats (Capra aegagrus hircus) to dental microwear texture analysis (DMTA). The study animals were divided into four groups, which received diets of increasing phytolith-based abrasiveness (L: lucerne based pellets, very low phytolith abrasion diet, acting as control; G: grass-based pellets, medium abrasive phytolith diet; GR: grass and rice husk pellets, high abrasion phytolith diet), or a diet with added external abrasives (GRS: the GR diet with add…
Efficient smart-camera accelerator: A configurable motion estimator dedicated to video codec
2013
Smart cameras are used in a large range of applications. Usually the smart cameras transmit the video or/and extracted information from the video scene, frequently on compressed format to fit with the application requirements. An efficient hardware accelerator that can be adapted and provide the required coding performances according to the events detected in the video, the available network bandwidth or user requirements, is therefore a key element for smart camera solutions. We propose in this paper to focus on a key part of the compression system: motion estimation. We have developed a flexible hardware implementation of the motion estimator based on FPGA component, fully compatible with…
