MECHANICAL, RHEOLOGICAL AND THERMAL EVALUATION OF POLY(LACTIC ACID) (PLA)/MICRO FIBRILLATED CELLULOSE (MFC) PLASTICIZED BIOCOMPOSITES PRODUCED WITH F…
2022
The use of Micro Fibrillated Cellulose (MFC) as filler for polymeric matrices attempts an increasing interest both in academia and industry. In this framework, encouraging results have been obtained using plasticizers, as dispersing aids, during twin-screw extrusion that optimizes the process parameters and avoid MFC agglomeration. In this work, two commercial typologies of waterborne solution of MFC (Exilva and Celish) were melt-compounded in a PLA matrix through semi-industrial twin-screw extruder and calendered, producing films of 150 μm thickness. These films were mechanically and thermally characterized, moreover the migration of the plasticizer along the time was evaluated through ana…
SAT0373 Role of Inkt Cells in Patients with Primary Sjogren Syndrome
2015
Background iNKT cells represent a T cell subset at the bridge between innate and adaptive immunity, playing a role in regulating auto-antibody-producing B cells before their entry into germinal centers. Therefore the absence and/or reduction of iNKT cells seem to increase auto-reactive B cell activation. Primary Sjogren9s syndrome (pSS) is a systemic autoimmune disease in which lymphocyte infiltration and organization in lymphoid structures of inflamed salivary glands occur. Objectives The aim of this study was to investigate the frequency of iNKT in the salivary glands and peripheral blood of patients with pSS and their function by using CD1d/aGalactosylceramide (aGalaCer) tetramers. Metho…
Lampedusa humanitarian emergency in 2011: the case of unaccompanied migrant minors
2012
The purporse of this paper is to highlight the situation of the unaccompanied foreign minors in the Italian legal system, paying special attention to the Lampedusa humanitarian emergency in 2011. The paper examines the legal measures regulating the status of unaccompanied foreign minors in the Italian legal system, in order to understand if they are efficient in giving protection and offering integration to these minors. The papers offers insights into the most vulnerable category of illegal immigrants Purpose - The purpose of this paper is to highlight the situation on the unaccompanied foreign minors in the Italian legal system, paying special attention to the Lampedusa humanitarian emerg…
Regional and age-dependent differences in the effect of wind on the migratory routes of Eleonora's Falcon.
2015
During migration, birds can show different responses to wind in relation to distance to the goal, experience, ecological barriers and visibility of landmarks. We analysed the effect of wind (tailwinds and crosswinds) on daily movement rates (forward and perpendicular) of Eleonora’s falcons using ARGOS satellite telemetry, during their trans-continental autumn migration to Madagascar, in relation to the different crossed regions and individuals’ age class. Our results showed that the effect of wind on daily movement rates was not uniform, being stronger in the farthest region from the migration goal, the Sahara desert, with adults being more affected than juveniles in this region. In the Sah…
Cellul�re Immunreaktionen gegen�ber homologen leberspezifischen Antigenen (HLP) bei chronischen Leberentz�ndungen
1974
Es wird eine Zweiphasentechnik des Leukocyten-Migrations-Inhibitionstestes beschrieben und zum Nachweis einer cellularen Immunreaktion gegenuber Leberantigenen bei chronisch-entzundlichen Lebererkrankungen eingesetzt. Mit dieser Technik wurde bei 85% der Patienten mit hypergammaglobulinamischer Verlaufsform einer chronisch-aktiven Hepatitis und 42% der Patienten mit aktiv fortschreitenden kryptogenen Lebercirrhosen eine Migrationshemmung nachgewiesen. Lebergesunde Kontrollen zeigten keine, Patienten mit dem Zustand nach Hepatitis und chronisch-persistierender Hepatitis selten eine Leukocytenmigrationsinhibition gegenuber leberspezifischen Antigenen. 17% der Patienten mit chronisch-aktiver H…
The European media discourse on immigration and its effects: a literature review
2018
To understand public opinion about immigration in Europe, one has to understand the media’s role in it. We present a literature review on research on media discourse on immigration and their effects. Despite differences in the way immigration and migrant groups are represented in European media, we can observe common patterns. Migrants are generally under-represented and shown as delinquents or criminals. Although, media framing differs based on specific migrant groups the discourse is focusing on, immigration coverage is often negative and conflict-centred. Frequent exposure to such media messages leads to negative attitudes towards migration, may activate stereotypical cognitions of migra…
Bidding for Research Funds. Inter-Fields Differences and Predictors of the Evaluation Scores: Insights from a Romanian National Competition for Postd…
2021
This study sought to address an important gap in the existent knowledge about the development of the Romanian research system by looking at a very specific population of young scholars who participated in the national competition for postdoctoral grants (2016) which included over 900 participants. The paper is structured by two main research objectives. Firstly, the analysis if focused on differences between scientific fields by looking at research entities which host young scholars’ grant proposals, gender balance, young scholars’ academic performance measured through a standardized indicator (Google Scholar H index), share of people trained abroad, and information about the evaluation pro…
Violencia de género en mujeres inmigrantes y españolas: magnitud, respuestas ante el problema y políticas existentes
2009
Objetivo: Comparar la prevalencia de la violencia de género entre mujeres inmigrantes y españolas. Describir sus respuestas ante esta situación y posibles diferencias entre ellas. Identificar intervenciones ya existentes en España sobre prevención y atención sociosanitaria de violencia de género dirigidas a inmigrantes. Métodos: Estudio transversal mediante encuesta autoadministrada en 10.202 mujeres que acudieron a centros de atención primaria en España (2006-2007). Análisis de contenido del informe de seguimiento de la ley 1/2004 de medidas de protección integral contra la violencia de género remitido por las comunidades autónomas (CC.AA.) (2005) y las leyes y planes autonómicos más recie…
Violence at School: A Sample of Young Muslims and Young Valencians
2014
AbstractViolence at school is considered to be an important issue in Spain, despite the fact that the majority of secondary education students reject it. Over the last decade awareness has been raised with regard to this problem. In this study we aim to analyze the perception of school violence held by two very different groups of secondary education students. A sample of young Muslims (n=88) and young Valencians (n=88) (aged between 12 and 18) has been used, all of whom live in the city of Valencia (Spain) and study in 12 secondary educational centers in the city. We observed significant differences in the perception that young Muslims and Valencians have of this violence. Both groups reje…
Bisphosphonates affect migration ability and cell viability of HUVEC, fibroblasts and osteoblasts in vitro
2010
Oral Diseases (2011) 17, 194–199 Objectives: Bisphosphonate-associated osteonecrosis of the jaw (BP-ONJ) is a side effect in patients being treated with bisphosphonates. The bisphosphonates most often associated with BP-ONJ are the highly potent nitrogen-containing bisphosphonates, e.g. pamidronate or zoledronate. In terms of BP-ONJ aetiology, several theories are being discussed: inhibition of bone remodelling, effect on soft tissues, and antiangiogenic effect of bisphosphonates. The aim of this in vitro study was to investigate the effect of different potent bisphosphonates on osteoblasts, fibroblasts and human umbilicord vein endothelial cells (HUVEC). Materials and methods: Three nitr…
