Planting in the pandemic : surveillance on social media
2023
This article looks at interest-driven and informal social media practices that have flourished in the pandemic period and its ensuing renaissance of domesticity. It investigates how tending plants and discussing them on social media serve as a particular site for connecting around loving and taking care of plants. Its focus is on the discursive means with which posters – guided by social media algorithms – rhetorically co-construct a morally acceptable version of a pandemic lifestyle around houseplants. More specifically, drawing on multimodal discourse studies, critical sociolinguistics and work on digital surveillance, it investigates how members of a Finland-based social media site obser…
Perception of pathogenic or beneficial bacteria and their evasion of host immunity: pattern recognition receptors in the frontline
2015
International audience; Plants are continuously monitoring the presence of microorganisms to establish an adapted response. Plants commonly use pattern recognition receptors (PRRs) to perceive microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) which are microorganism molecular signatures. Located at the plant plasma membrane, the PRRs are generally receptor-like kinases (RLKs) or receptor-like proteins (RLPs). MAMP detection will lead to the establishment of a plant defense program called MAMP-triggered immunity (MTI). In this review, we overview the RLKs and RLPs that assure early recognition and control of pathogenic or beneficial bacteria. We also highlight the crucial func…
Fracture and fatigue of titanium narrow dental implants: New trends in order to improve the mechanical response
2019
Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order to determine their reliability and to evaluate the causes of the fracture. These NDIs were compared with other similar implants, made with alloyed titanium with 15% Zr and with 12% strained titanium. Original implants were tested under static and fatigue conditions, simulating the tri-axial loads in the mouth by means of a Bionix hydraulic test machine. Fractography was studied using field-emission scanning electron microscopy (FSEM). The results showed that cp-Ti NDI exhibits low strength f…
The Brand-Land Identity of Etna Volcano Valley Wines: A Policy Delphi Study
2022
This is the first study on the brand–land link for quality wines with a strong identity produced in extreme territories using the Policy Delphi methodology. The objective of this study is to assess the existence of a relationship between the wine brand and the territory of origin for wines produced in the Etna valley in Sicily (southern Italy). Awareness among producers and stakeholders of the recognizability of local wines by the market was investigated. Moreover, the forecasts/reliability, issues/importance, options/feasibility, and goals/desirability of development factors for wines with a brand–land link in the Etna valley were analyzed. The results were used to design a mod…
Are Red Lists really useful for plant conservation? The New Red List of the Italian Flora in the perspective of national conservation policies
2013
La nuova Lista Rossa della flora Italiana comprende tutte le "policy" specie italiane e altre specie di nota conservazione e comprende 400 taxa di cui il 65% sono minacciate di estinzione. La Lista Rossa si basa su un enorme data-set georeferenziato utile per gli scopi di conservazione. - The New Red List of the Italian Flora includes all the Italian policy species and other species of known conservation concerns for a total of 400 taxa, 65% of which are threatened with extinction. The Red List is based on a huge georeferenced data-set useful for conservation purposes. -
Estimation of the pollen and seed production of common ragweed in Europe
2007
International audience; Common ragweed (Ambrosia artemisiifolia L.) is an invasive weed of fieldcrops and human-disturbed habitats in Europe. As well as in its natural range (NorthAmerica), common ragweed is a threat to human health due to its abundant allergenicpollen release. Most studies have been focused on airborne pollen monitoring, but todate, no data have been available on precise individual plant pollen and seed productionrelated to plant traits growing in natural environment and on their corresponding sourceof variation. The aim of this study was to evaluate pollen and seed production of commonragweed plants in several populations in France. Seasonal pollen production per plantran…

Influence of different dehydration levels on volatile profiles, phenolic contents and skin hardness of alkaline pre-treated grapes cv Muscat of Alexa…
2020
A dehydration experiment was carried out on Vitis vinifera L. cv Muscat of Alexandria (synonym Zibibbo) following the process for the production of renowned special dessert wines produced on Pantelleria island (Sicily, Italy). Harvested berries were pre-treated in a sodium hydroxide dipping solution (45 g/L, dipped for 185 s, 25 °
Les femmes de l'aristocratie face au pouvoir Plantagenêt en Normandie (1150-1204)
2006
Dans la société aristocratique anglo-normande quelques femmes puissantes sont impliquées dans le rapport de force qui oppose le duc et les nobles. Le prince tente d'exploiter à son profit les domaines qu'elles détiennent et il arrive qu'elles soient clairement instrumentalisées. Mais elles tentent de préserver leurs intérêts et ceux de leur lignage parfois avec succès.
