Short-term impact of biogas digestates on soils microbial communities
2022
International audience; Anaerobic digestion of organic waste is considered a key process to produce renewable energy to meet the growing sustainable energy demand. Digestates can be used in agriculture as soil amendments and improve crop yields. However, their use at large scale in agricultural fields still requires to prove their innocuity on soil biota, especially on microorganisms that play important roles in soil ecosystem. Here, we designed a microcosm experiment to compare the short-term (42-days) effects of four different digestates (derived from cattle manure, energy crop, food residues or slurry with bio-waste) on the soil microbial communities. Each digestate was applied on three …
Numerical simulation of river-bed variations: Sensitivity analyses with respect of the initial hydraulic roughness
2020
Two elements affect the efficacy of the numerical models of mobile-bed evolution: the prediction of the hydraulic roughness, related with both sediment distribution on the bed and flow depth, and the prediction of the hydraulic sorting, when the distribution of sediments on the bed is not uniform. In this work the bed profile variation is simulated, by using a numerical model proposed in previous works, in function of the variation of the friction factor, that reflects the coarsening of median sediment diameter, due to armouring process, and the variation of flow conditions. The variation of grains-size distribution of the bed material is predicted by using a probabilistic approach and the …
'Good to Repeat': Making Random Access Near-Optimal with Repeated Contentions
2020
Recent advances on WLAN technology have been focused mostly on boosting network capacity by means of a more efficient and flexible physical layer. A new concept is required at MAC level to exploit fully the new capabilities of the PHY layer. In this article, we propose a contention mechanism based on Repeated Contentions (ReCo) in frequency domain. It provides a simple-to-configure, robust and short-term fair algorithm for the random contention component of the MAC protocol. The throughput efficiency of ReCo is not sensitive to the number of contending stations, so that ReCo does not require adaptive tuning of the access parameters for performance optimization. Efficiency and robustness is …
Characterization of Rabbit Mesenchymal Cell Attachment on Calcium Phosphate Surface
2014
In the current study, the effect of three different treated surfaces of hydroxyapatite and β-tricalcium phosphate on mesenchymal cell attachment has been investigated. Calcium phosphate powders have been synthesized, uniaxially pressed, polished and sintered. Mesenchymal cells have been seeded onto unpolished, polished and polished-thermally etched ceramic samples. The ceramic samples have been characterized by XRD, FTIR and SEM. Results have shown that the best cell attachment and morphology are on the unpolished surface indicating that relatively rough surface is better for cell application.
Uno studio comparativo in silico sui possibili target di Ataluren e analoghi farmaci promotori di readthrough di codoni di stop prematuri
2019
E’ noto in letteratura che Ataluren (acido 5-(fluorofenil)-1,2,4-ossadiazolil-benzoico) sia in grado di sopprimere le mutazioni non senso favorendo il readthrough dei codoni di stop prematuri, anche se il suo meccanismo di azione non risulta ancora chiaro. La probabile interazione tra Ataluren e CTFR-mRNA è stata precedentemente studiata mediante dinamica molecolare. In questo studio1, abbiamo esteso il modeling del probabile meccanismo di azione di Ataluren mediante approcci computazionali completementari, quali Induced Fit Docking (IFD), Quantum Polarized Ligand Docking (QPLD), metodi MM-GBSA e mutagenesi computazionale. Oltre a considerare il CTFR-mRNA, sono stati presi in considerazione…
Reflexiones sobre la concurrencia de violencia económica en el contexto de familia : impacto y mecanismos para su neutralización
2021
Through this work we carry out a dissertation on the phenomenon of economic violence, as a manifestation of gender violence, in the family context, and, especially, from the perspective of the divorce framework. We will analyze the harmful effects that it produces, the damage that it triggers on the most basic and essential interests of the family, and its use as a control mechanism by the aggressors. In addition to a vision of the different mechanisms that, enshrined in our legal system, serve to distort it.
Rompé tus barreras: Un análisis sobre el uso del coaching ontológico en la plataforma de entrenamiento de Nike en Buenos Aires
2020
In recent times, coaching has become relevant in heterogeneous discourses and practices in the economic, political and cultural fields of contemporary societies. Based on our ethnographic analysis of different training sessions on the Nike+ Run Club platform in Buenos Aires, in this article we study how ontological coaching operates in the field of sport and races. Then, we ask about how people who attend this platform appropriate coaching techniques to manage emotions, moods, and body effects according to the business entrepreneurship logic. Through this work, the ethnographic results are articulated with a reflection about the theory, practice, and values of the ontological coaching, wher…
Silver-loaded nanoparticles affect ex-vivo mechanical behavior and mineralization of dentin
2019
Background: The aim was to evaluate the effect of silver loaded nanoparticles (NPs) application on the triboscopic, crystallographic and viscoelastic properties of demineralized dentin. Polymethylmetacrylate-based NPs and Ag loaded NPs were applied on demineralized dentin. Material and Methods: Treated and untreated surfaces were probed by a nanoindenter to test viscoelasticity, and by atomic force microscopy to test nanoroughness and collagen fibril diameter. X-ray diffraction and transmission electron microscopy through selected area diffraction and bright-field imaging were also used. Results: Dentin treated with Ag-NPs attained the lowest complex modulus, and the highest tan delta value…
Thriving Rough Sets: 10th Anniversary - Honoring Professor Zdzisław Pawlak's Life and Legacy & 35 Years of Rough Sets
2017
This special book is dedicated to the memory of Professor Zdzisław Pawlak, the father of rough set theory, in order to commemorate both the 10th anniversary of his passing and 35 years of rough set theory. The book consists of 20 chapters distributed into four sections, which focus in turn on a historical review of Professor Zdzisław Pawlak and rough set theory; a review of the theory of rough sets; the state of the art of rough set theory; and major developments in rough set based data mining approaches. Apart from Professor Pawlak’s contributions to rough set theory, other areas he was interested in are also included. Moreover, recent theoretical studies and advances in applications are a…
Neljännesunssi yhdeksälläkymmenellä taalalla : kotoutuksen sietämätön keveys William Burroughsin suomennoksissa
2015
Käännösgraduni tarkastelee kotouttamista ja vieraannuttamista valitsemissani katkelmissa William Burroughsin suomennoksia, omani mukaan lukien. Se sisältää johdannon, käännösnäytteen, käännöspäiväkirjan ja analyysin. Olen valinnut tutkimusmateriaalini yrittäen saada kirjailijan monipuolisesta tuotannosta mukaan mahdollisimman kattavan kuvan – toisaalta valintaa on ohjannut se, mitä kirjailijalta on aiemmin suomennettu. Käännöstieteen teorian osalta tukeudun tutkielmassani mm. Ritva Leppihalmeen, Outi Paloposken, Irma Sorvalin, Katja Vuokon ja Lawrence Venutin ajatteluun. Metodiksi olen valinnut vertailevan lähestymistavan: tarkastelen suomennoksia ja paikallistan niiden keskinäisiä eroja. N…
