Macro-micro relationship in nanostructured functional composites
2012
This paper examines the results of the characterization of two functional composites: Poly(methyl methacrylate) (PMMA)-Ce:YAG (yttrium aluminium garnet doped with cerium) and PMMA-cobalt hexacyanoferrate (CoHCF). The composites were prepared as possible emitters in the fields of lighting thermal sensors. The prepared composites were char- acterized using transmission electron microscopy (TEM), nuclear magnetic resonance (NMR) spectroscopy, thermogravi- metric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analyses to study the correlation between micro and macro characteristics. We found that the molecular interactions of the two different fill…
High-contrast sub-Doppler absorption spikes in a hot atomic vapor cell exposed to a dual-frequency laser field
2017
International audience; The saturated absorption technique is an elegant method widely used in atomic and molecular physics for high-resolution spectroscopy, laser frequency standards and metrology purposes. We have recently discovered that a saturated absorption scheme with a dual-frequency laser can lead to a significant sign reversal of the usual Doppler-free dip, yielding a deep enhanced-absorption spike. In this paper, we report detailed experimental investigations of this phenomenon, together with a full in-depth theoretical description. It is shown that several physical effects can support or oppose the formation of the high-contrast central spike in the absorption profile. The physi…
Role for D1-like and D2-like dopamine receptors in the modulation of intestinal motility in mice
2015
Objective: In the last years a plethora of studies addressed dopamine (DA) as a modulator within the enteric nervous system (ENS), controlling gastrointestinal (GI) functions via activation of D1- and D2-like receptors. However, the effective role and functional significance of DA in the ENS, and the contribution of its receptors, are still a matter of debate. Pathological alterations of dopaminergic system in the gut may be likely implicated in different motor GI disorders, including dyspepsia and gastroparesis. Thus, a detailed characterization of the enteric dopaminergic signalling is necessary. The aim of this study was to explore the role of DA in the GI tract, using as model the mouse…
Influence of Mn site doping on electrical resistivity of polycrystalline La1-yAyMn1-xBxO3 (A=Ba, Sr; B=Cu, Cr, Co) Manganites
2008
We have the measured electrical resistivity of La1-yBayMn1-xCuxO3 (0.17?y?0.30; 0.04?x?0.10), La1-ySryMn1-xCrxO3 and La1-ySryMn1-xCoxO3 (0.270?y?0.294; 0.02?x?0.10) polycrystalline samples in the 25-325 K temperature range. The increase of Mn site doping concentration leads to an increase of the electrical resistivity of the samples and the appearance of a ?double-peak? structure in the electrical resistivity versus temperature graphs. The first peak represents the insulator-metal transition in vicinity of the paramagnetic-ferromagnetic transition (TC). We have found that the intensity of the second peak increases with an increase of concentration of Mn substituents, due to the hole scatter…
Presence of endophytic bacteria in Vitis vinifera leaves as detected by Fluorescence in situ hybridization
2010
Fluorescence in situ hybridization (FISH) in combination with confocal laser scanning microscopy (CLSM) was applied to detect and localize bacterial colonies in leaf tissues of Vitis vinifera. Leaves were cleared to minimize the autofluorescence of plant fragments. The use of fluorescently labeled bacterial probe EUB338 on discolored grapevine leaf disks allowed the estimation of the spatial distribution of different bacterial colonies. In particular, bacterial colonies were found in veins, cells, hairs, intercellular spaces, and in cut edges of leaf disks of both non-Acremonium byssoides-colonized and A. byssoides-colonized leaves of five different cultivars. Furthermore, CLSM confirmed th…
Cinética de dolor postoperatorio, consumo de analgésicos y recuperación de las actividades de la vida diaria en pacientes sometidos a fundoplicatura …
2017
Introducción: El tratamiento de elección para la enfermedad por reflujo gastroesofágico es la fundoplicatura Nissen laparoscópica (FNL), pero su manejo ambulatorio no ha sido hasta el momento ampliamente aceptado por la comunidad quirúrgica. Uno de los elementos principales en el éxito ambulatorio de esta patología, es el adecuado control del dolor postoperatorio, teniendo gran relevancia clínica la cinética de recuperación de las actividades de la vida diaria. Objetivos: Nuestra hipótesis de trabajo se basa en que la FNL es un procedimiento susceptible de realizarse en programas de Cirugía Mayor Ambulatoria (CMA) al ser equiparable en términos de dolor percibido, consumo de analgésicos y r…
SU UN POSSIBILE COLLEGAMENTO FRA IL CONTRADDITTORIO “(ENDO)PROCEDIMENTALE” NELL’ITER DI FORMAZIONE DEGLI ATTI “IMPO-ESATTIVI” E LA TUTELA CAUTELARE N…
2022
Lo scritto affronta il tema dell’eventuale refluenza che possa avere, nella fase cautelare del processo tributario, la celebrazione (o la mancata celebrazione) del “contraddittorio” anteriore all’emanazione di un avviso di accertamento con efficacia impo-esattiva nel campo dell’imposizione diretta e dell’iva. A tal uopo si formula una sorta di “stress-test” giuridico in cui, da un canto si valutano ipotetici argomenti che priverebbero il previo contradditorio di una sua autonoma funzione difensiva, che la stessa sarebbe comunque e meglio perseguibile nel processo, e dall’altro si valuta se quegli argomenti “resistano” anche con riguardo alla fase cautelare del giudizio di primo grado avente…
L’art. 12 dello statuto ed il contraddittorio “endoprocedimentale”tributario: una questione ancora aperta
2015
Le Sezioni Unite della Corte di Cassazione, recependo gli spunti offerti dallagiurisprudenza comunitaria, hanno recentemente affermato l’immanenza del prin-cipio del contraddittorio endoprocedimentale in ambito tributario. La questione,diffusamente discussa in dottrina con opinioni non convergenti, sembrerebbe, per-tanto, aver raggiunto un punto fermo. Tuttavia, con una recentissima ordinanzadi rimessione, la sez. VI-tributaria della Suprema Corte ha riaperto la problema-tica, chiedendo alle Sezioni Unite di chiarire esattamente se vi sia e quale sia lafonte normativa di tale principio nel nostro ordinamento, se essa possa essere rav-visata nell’ultimo comma dell’art. 12 dello Statuto dei d…
