Remarks on regularity for p-Laplacian type equations in non-divergence form
2018
We study a singular or degenerate equation in non-divergence form modeled by the $p$-Laplacian, $$-|Du|^\gamma\left(\Delta u+(p-2)\Delta_\infty^N u\right)=f\ \ \ \ \text{in}\ \ \ \Omega.$$ We investigate local $C^{1,\alpha}$ regularity of viscosity solutions in the full range $\gamma>-1$ and $p>1$, and provide local $W^{2,2}$ estimates in the restricted cases where $p$ is close to 2 and $\gamma$ is close to 0.
A model of degassing for Stromboli volcano
2010
International audience; A better understanding of degassing processes at open-vent basaltic volcanoes requires collection of new datasets of H2O–CO2–SO2 volcanic gas plume compositions, which acquisition has long been hampered by technical limitations. Here, we use the MultiGAS technique to provide the best-documented record of gas plume discharges from Stromboli volcano to date. We show that Stromboli's gases are dominated by H2O (48–98 mol%; mean, 80%), and by CO2 (2–50 mol%; mean, 17%) and SO2 (0.2–14 mol%; mean, 3%). The significant temporal variability in our dataset reflects the dynamic nature of degassing process during Strombolian activity; which we explore by interpreting our gas m…
Lidar detection of carbon dioxide in volcanic plumes
2015
Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…

Conflicts in workplace in technology-mediated communication
2017
Konfliktit työyhteisön teknologiavälitteisessä vuorovaikutuksessa. Tämän tutkielman tavoitteena oli kuvata työntekijöiden havaintoja konflikteista, jotka ilmenivät työpaikkojen teknologiavälitteisessä vuorovaikutuksessa. Työntekijöiden havaintoihin pohjaten tutkielma pyrki kasvattamaan ymmärrystä työelämässä ja teknologiavälitteisessä vuorovaikutuksessa ilmenevistä konflikteista etsimällä vastauksia siihen, millaisia syitä, seurauksia ja lopputuloksia konflikteilla on työyhteisöjen teknologiavälitteisessä vuorovaikutuksessa. Konfliktien ja niiden hallintakeinojen ymmärtäminen on tärkeää työyhteisöille ja niissä toimiville työyhteisön jäsenille. Tutkielman menetelmänä käytettiin teoriasidonn…
Relaxation of a weakly discontinuous functional depending on one control function
2008
The paper considers an optimal control problem of the typewhere the set M of admissible controls consists of all measurable vector‐functions h, which can take only two values h1 or h2. It is shown that the relaxation of this problem can be explicitly computed by rank‐one laminates.
Saint-Dizier « la Tuilerie » (Haute-Marne) : trois sépultures d’élite du VIe siècle
2019
In 2002, excavations carried out by Marie-Cécile Truc (Inrap) at Saint-Dizier led to the discovery of four graves of exceptional wealth, containing a young woman, two men and a horse, dated to c. 525-550 AD. Dressed and adorned with numerous jewels, the young female was laid in a coffin upon which were placed vessels in glass, copper alloy goblet and ceramic. Each male had been buried in an excavated funerary chamber, built within an oak frame. They were laid in their coffins along with their personal clothing, including a ceremonial sword with two rings added to the pommel. The larger weapons (throwing axes, shields, lances and angons) as well as various utensils were placed either on the …
Les types de temps associés aux risques d’inondations et d’érosions en Camargue : éléments de diagnostic et de prospectives pour le 21e siècle (1993-…
2010
Les fortes surcotes marines et les fortes vagues sont les principaux aléas météo-marins associés aux risques de submersion et d’érosion du littoral camarguais. Sur la période 1993-2002, une forte fréquence mensuelle de très hautes surcotes marégraphiques est généralement associée à une forte fréquence de très hautes vagues. Ces deux phénomènes locaux se produisent principalement lorsqu'une dépression autour du Golfe de Gascogne est associée à des hautes pressions sur l’Europe Centrale. La fréquence mensuelle de ce type de temps nous renseigne sur la probabilité d’occurrence de fortes surcotes marégraphiques et vagues en Camargue. Au 21e siècle, la fréquence du type de temps associé aux plus…
Predominance of Type 1 Innate Lymphoid Cells in the Rectal Mucosa of Patients With Non-Celiac Wheat Sensitivity: Reversal After a Wheat-Free Diet.
2016
OBJECTIVES: Non-celiac wheat sensitivity (NCWS) is defined as a reaction to ingested wheat after exclusion of celiac disease and wheat allergy. As its pathogenesis is incompletely understood, we evaluated the inflammatory response in the rectal mucosa of patients with well-defined NCWS. METHODS: The prospective study included 22 patients with irritable bowel syndrome (IBS)-like clinical presentation, diagnosed with NCWS by double-blind placebo-controlled challenge. Eight IBS patients not improving on wheat-free diet were used as controls. Two weeks after oral challenge was performed with 80 grams of wheat daily, cells were isolated from rectal biopsies and thoroughly characterized by fluore…
Agronomical evaluation of Sicilian biotypes of Lavandula stoechas L. spp. stoechas and analysis of the essential oils
2015
The aim of this study was to characterize wild lavender, which was collected in three different areas of Sicily (Italy),according to agronomic and chemical evaluation. The collection sites were located in Pantelleria island, Partinico (a warm sub-area of Lauretum) and Castelbuono (a middle sub-area of Lauretum). All the populations were identified as Lavandula stoechas L. ssp. stoechas. Essential oils were extracted by hydrodistillation and analyzed by gas chromatography– flame ionization detector (GC–FID) and GC–mass spectrometry (GC–MS). GC–FID and GC–MS analyses permitted the identification of 101 components from the essential oils. We analyzed only the flowers and leaves of L. stoechas …
