Textural-chemical changes and deformation conditions registered by phyllosilicates in a fault zone (Pic de Port Vieux thrust, Pyrenees)
2017
International audience; Synkinematic phyllosilicates in fault zones can be used to deduce the deformation mechanisms and the conditions of fault activity, as their chemical composition, crystal structure and texture can record the different stages of deformation and fluid-rock interactions. The Pic de Port Vieux, a second-order thrust related to the major Gavarnie thrust in the southern central part of the Pyrenees Axial Zone, juxtaposes Triassic pelites of the hanging wall and Cretaceous limestones of the footwall. In order to investigate the mineralogical and geochemical changes and constrain the deformation conditions of thrusting, characterization of phyllosilicates was performed along …
MICA-129 Dimorphism and Soluble MICA Are Associated With the Progression of Multiple Myeloma
2018
Natural killer (NK) cells are immune innate effectors playing a pivotal role in the immunosurveillance of multiple myeloma (MM) since they are able to directly recognize and kill MM cells. In this regard, among activating receptors expressed by NK cells, NKG2D represents an important receptor for the recognition of MM cells, being its ligands expressed by tumor cells, and being able to trigger NK cell cytotoxicity. The MHC class I-related molecule A (MICA) is one of the NKG2D ligands; it is encoded by highly polymorphic genes and exists as membrane-bound and soluble isoforms. Soluble MICA (sMICA) is overexpressed in the serum of MM patients, and its levels correlate with tumor progression. …
Comparison of different uncertainty techniques in urban stormwater quantity and quality modelling
2011
Abstract Urban drainage models are important tools used by both practitioners and scientists in the field of stormwater management. These models are often conceptual and usually require calibration using local datasets. The quantification of the uncertainty associated with the models is a must, although it is rarely practiced. The International Working Group on Data and Models, which works under the IWA/IAHR Joint Committee on Urban Drainage, has been working on the development of a framework for defining and assessing uncertainties in the field of urban drainage modelling. A part of that work is the assessment and comparison of different techniques generally used in the uncertainty assessm…
Power Consumption Analysis of Operating Systems for Wireless Sensor Networks
2010
In this paper four wireless sensor network operating systems are compared in terms of power consumption. The analysis takes into account the most common operating systems-TinyOS v1.0, TinyOS v2.0, Mantis and Contiki-running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and t…

Computational study of defects in ideal phengite
2009
Phengite is the name of a series designating the “potassic dioctahedral micas between, or close to, the joins muscovite-aluminoceladonite and muscovite-celadonite” (Rieder et al. 1998). These micas play a important role in most petrogenetic reactions occurring in high-pressure (HP) metamorphic environments; they are useful geothermobarometers and participate in reactions as H2O carriers in the subduction zone. In this work we have employed atomistic simulations techniques to model defects, evaluate the most stable defect species and determine the most likely diffusion mechanism in crystals. We have calculated the defect formation energies for vacancies, impurities and interstitials, Frenkel…
La proposta di regolamento MiCA e la disciplina delle pratiche commerciali scorrette
2022
The most part of European and domestic supervisory authorities have underlined the likelihood that either the issuing and the negotiation of cryptoassets may be the final outcome of unfair and deceptive commercial practices. The discipline laid down by the Directive 2005/29/ CE – now expressely recalled by the MiCAR Proposal – seems to be crucial for the best functioning of the market at stake. The Author stresses how the interplay between «horizontal» and «vertical» measures needs the interpreters play a pivotal role, in order to grant the best understanding of the circumstances of the case as well as the best using of the «professional diligence» general clause.
Il ruolo del white paper sulle offerte al pubblico di cripto-attività alla luce della proposta MiCA
2022
La proposta MiCA, nel regolare il white paper sulle offerte di crypto-assets, sembra tenere in considerazione i benefici e i limiti dei sistemi di voluntary e di mandatory disclosure, non optando integralmente né per il primo, né per il secondo. In quest’ottica, se può condividersi l’approccio regolamentare diretto a graduare, a seconda della tipologia di token offerto, sia il contenuto che l’assoggettamento del documento a mera notifica o ad approvazione ex ante da parte dell’Autorità competente, dubbi sorgono in ordine all’indistinta allocazione dell’onere della prova in capo all’oblato, nei casi di violazione della disciplina del relativo white paper.
El procés d'unificació de l'ortografia catalana
1994
The publication of the Normes ortográfiques de l'IEC (1913) and its adoption in the entire linguistic region in 1932 in the Valencian Country with the so-called Normes de Castelló was the result of a process in which differing spelling norms had to be standardized. The author examines in detail the norms used in several popular and dialectic magazines published in Barcelona (La Esquella de la Torratxa), Valencia (El Micalet de Valensia) and Palma de Majorca (En Figuera).
MONITORING AND USE OF ANTIMYCOTICS FOR SYSTEMIC USE SUPPLIED BY THE STATE HOSPITAL PHARMACY OF MARSALA (TP), ITALY: MYCAMINE® (MICAFUNGIN)
2014
Micafungin is an antimycotic drug and represents an important addition to the available therapies for the treatment of systemic fungal infections. Micafungin is used in the treatment of invasive candidiasis, oesophageal and prophylaxis of Candida infections. It inhibits, in a non-competitive way, the synthesis of 1,3-b-D-glucan, a component of fungal cell wall and is rapidly distributed into the tissues. It has a high-rate bond with respect to plasma protein; the above mentioned bond is independent from the concentration of the drug. It is metabolized through the liver, being not subject to intense metabolic transformations until the excretion. There is no evidence of systemic accumulation …
