MAPs in Sicily: cultivation, uses, and potentiality
2013
In Sicily, MAPs have been used and cultivated for centuries, with many uses ranging from the preparation of fresh or stored food items, flavoring of foods and beverages, home-made human or animal therapy or even aesthetical purposes. Many of them grow spontaneously into such areas, and are claimed to play a significant role inside land biodiversity. The widespread belief that only under “natural” conditions MAPs find their optimum quality features has driven in many cases to their uncontrolled collection from the wild, and as a result many of them are nowadays at a risk of extinction. The field cropping of such spontaneous species could play an important role in safeguarding biodiversity, a…
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…
Microbial deposits in the aftermath of the end-Permian mass extinction: A diverging case from the Mineral Mountains (Utah, USA)
2015
40 pages; International audience; The Lower Triassic Mineral Mountains area (Utah, USA) preserves diversified Smithian and Spathian reefs and bioaccumulations that contain fenestral-microbialites and various benthic and pelagic organisms. Ecological and environmental changes during the Early Triassic are commonly assumed to be associated with numerous perturbations (productivity changes, acidifica-tion, redox changes, hypercapnia, eustatism and temperature changes) post-dating the Permian–Triassic mass extinction. New data acquired in the Mineral Mountains sediments provide evidence to decipher the relationships between depositional environments and the growth and distribution of microbial …
Association between climate and new daily diagnoses of COVID-19
2020
AbstractBackgroundAlthough evidence is accumulating that climate conditions may positively or negatively influence the scale of coronavirus disease 2019 (COVID-19) outbreaks, uncertainty remains concerning the real impact of climate factors on viral transmission. Methods. The number of new daily cases of COVID-19 diagnosed in Verona (Italy) was retrieved from the official website of Veneto Region, while information on daily weather parameters in the same area was downloaded from IlMeteo website, a renowned Italian technological company specialized in weather forecasts. The search period ranged between March 1 to November 11, 2020. The number of new daily COVID-19 cases and meteorological da…
ON NEW ROLES IN DIGITAL ENVIRONMENTS: E-DOCTORS AND E-PATIENTS
2014
Medical communication can be both a dialogue between expert-to-expert or expert-to-laymen (Cordella, 2004; Bowles, 2006; Candlin, 2006; Maynard and Hudak 2008; Lutfey and Maynard 1998; Heritage 2010; Heritage and Clayman, 2010 among others). In this last exchange, the doctor treats the patient as an ‘understanding recipient of medical reasoning’ (Peräkylä 1997) and language is simplified for communicative reasons (Koch-Weser et al., 2009). Patients are assumed as having little medical knowledge, which affects their understanding of medical terms and eventually leads to poor communication and to patients’ dissatisfaction (Candlin, Bruton and Leather, 1974; Coulthard and Ashby, 1975; Todd and…
On optimizing firewall performance in dynamic networks by invoking a novel swapping window-based paradigm
2018
Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and controlled on the Internet. Additionally, an everincreasingly amount of sensitive information will be stored on various networks. A good and efficient firewall strategy will attempt to secure this information, and to also manage the large amount of inevitable network traffic that these devices create. The goal of this paper is to propose a framework for designing optimized firewalls for the IoT. This paper deals with two fundamental challenges/problems encountered in such firewalls…
New constraints on the Al 25 (p,γ) reaction and its influence on the flux of cosmic γ rays from classical nova explosions
2021
The astrophysical Al25(p,γ)Si26 reaction represents one of the key remaining uncertainties in accurately modeling the abundance of radiogenic Al26 ejected from classical novae. Specifically, the strengths of key proton-unbound resonances in Si26, that govern the rate of the Al25(p,γ) reaction under explosive astrophysical conditions, remain unsettled. Here, we present a detailed spectroscopy study of the Si26 mirror nucleus Mg26. We have measured the lifetime of the 3+, 6.125-MeV state in Mg26 to be 19(3)fs and provide compelling evidence for the existence of a 1- state in the T=1,A=26 system, indicating a previously unaccounted for=1 resonance in the Al25(p,γ) reaction. Using the presently…
Forest management optimization across spatial scales to reconcile economic and conservation objectives
2019
Conflicts between biodiversity conservation and resource production can be mitigated by multi-objective management planning. Optimizing management for multiple objectives over larger land areas likely entails trading off the practicability of the process against the goodness of the solution. It is therefore worthwhile to resolve how large areas are required as management planning regions to reconcile conflicting objectives as effectively as possible. We aimed to reveal how the extent of forestry planning regions impacts the potential to mitigate a forestry-conservation conflict in Finland, represented as a trade-off between harvest income and deadwood availability. We used forecasted data f…
The Disorienting Aesthetics of Mashed-Up Anthropocene Environments
2022
This paper describes the disorienting aesthetics of some environments that are characteristic of the Anthropocene. We refer to these environments as 'mashed-up' and present three dimensions - phenomenological, epistemological and narrative - of the aesthetic disorientation they can trigger. We then advance the suggestion that a rich, nuanced and meaningful aesthetic experience of mashed-up Anthropocene environments (MAEs) calls for a mode of appreciation grounded on performative practices of aesthetic familiarisation with particular MAEs and entities and processes thereof. Familiarisation with MAEs, we further note, can have disorienting codas of its own. It can reveal and highlight, rather…
Accelerated stabilization of coherent photon states
2018
| openaire: EC/H2020/681311/EU//QUESS Control and utilization of coherent states of microwave photons is a ubiquitous requirement for the present and near-future implementations of solid-state quantum computers. The rate at which the photon state responds to external driving is limited by the relaxation rate of the storage resonator, which poses a trade-off between fast control and long storage time. Here, we present a control scheme that is designed to drive an unknown photon state to a desired coherent state much faster than the resonator decay rate. Our method utilizes a tunable environment which acts on an ancillary qubit coupled to the resonator. By periodically resetting the qubit and…
