Interactions between volatiles and lipids in complex systems
1998
Partition equilibria of three aroma compounds in three different biphasic systems were studied by a liquid/liquid partition technique to investigate interactions that occur between volatiles and lipids in biphasic solutions. The lipids used were linoleic acid and ricinoleic acid and tetradecane as a model. The three aroma compounds were ethyl acetate, 2,5-dimethylpyrazine, and oct-1-en-3-ol. The results showed that the intermolecular forces involved were weak. Infrared spectroscopy was then performed on binary systems (tetradecane and linoleic acid or aroma compound) and on ternary systems (tetradecane, linoleic acid, and aroma compound) to determine the nature of the interactions. This met…
Interactive effects of increased temperature and gadolinium pollution in Paracentrotus lividus sea urchin embryos: a climate change perspective
2021
Gradual ocean warming and marine heatwaves represent major threats for marine organisms already facing other anthropogenic-derived hazards, such as chemical contamination in coastal areas. In this study, the combined effects of thermal stress and exposure to gadolinium (Gd), a metal used as a contrasting agent in medical imaging which enters the aquatic environment, were investigated in the embryos and larvae of the sea urchin Paracentrotus lividus. Embryos were exposed to six treatments of three temperatures (18 °C, 21 °C, 24 °C) and two Gd concentrations (control: 0 μM; treated: 20 μM). With respect to developmental progression, increased temperature accelerated development and achievemen…
1H, 13C, and 15N NMR chemical shift assignment of the complex formed by the first EPEC EspF repeat and N-WASP GTPase binding domain
2021
AbstractLEE-encoded effector EspF (EspF) is an effector protein part of enteropathogenic Escherichia coli’s (EPEC’s) arsenal for intestinal infection. This intrinsically disordered protein contains three highly conserved repeats which together compose over half of the protein’s complete amino acid sequence. EPEC uses EspF to hijack host proteins in order to promote infection. In the attack EspF is translocated, together with other effector proteins, to host cell via type III secretion system. Inside host EspF stimulates actin polymerization by interacting with Neural Wiskott-Aldrich syndrome protein (N-WASP), a regulator in actin polymerization machinery. It is presumed that EspF acts by di…
Internet and People with Intellectual Disability: A Bibliometric Analysis
2020
The use of the Internet by people with intellectual disabilities is an area of study that has captured the interest of scientists in recent years. The studies have focused on analyzing specific aspects such as usability, the activities carried out online, and Internet benefits and risks, among others. The reviews published on this matter have been of a narrative or systematic approach. The present study aimed to examine the academic output in the field of Internet and people with intellectual disability from a bibliometric perspective. A sample of 95 documents related to the topic was retrieved from the core collection of Web of Science (WoS) and analyzed using the bibliometrix R-Tool. Find…
Client’s role and participation in stroke physiotherapy encounters: an observational study
2016
AbstractClient participation is a basic principle in rehabilitation encounters. Coping at home after stroke requires self-confidence and autonomy, which can be enhanced by active collaboration and knowledge sharing. Earlier studies show, however, that clients are not always offered the role of an active participant in physiotherapy practice. A contradiction remains between official rhetoric and clinical practice. The purpose of this study was to investigate the interaction between the client and the physiotherapist in stroke rehabilitation sessions. Eight video-recorded treatment sessions were observed after an educational intervention that focused on client participation. Discourse analysi…
Validity and reliability of the motivation for physical activity (RM4-FM) questionnaire
2021
There is a lack of validated instruments measuring motivation for physical activity (RM4-FM) in the Finnish language. The study examined the translated RM4-FM instrument’s psychometric properties in a sample of healthy, older Finnish adults. RM4-FM was translated and linguistically validated adhering to published guidelines. 65–75-year olds (n=102), completed the RM4-FM, the physical activity acceptance questionnaire (PAAQ) and sociodemographic characteristics questionnaires electronically. The RM4-FM was readministered one month after the initial assessment. RM4-FM translated well into Finnish. Motivation dimension scores were skewed towards high internal and low external motivation. A flo…
Les étudiants de la génération Y en formation
2013
National audience; La génération Y suscite débats et questionnements au niveau pédagogique. C'est actuellement celle qui constitue la majorité des étudiants en formation paramédicale. Peu désireuse d'un enseignement dispensant uniquement des savoirs, cette génération demande que le formateur s'adapte aux étudiants pour susciter leur intérêt et donc leur engagement dans la formation. Cela passe par certaines caractéristiques générationnelles, à commencer par la relation entre le formateur et les étudiants mais aussi par le travail en groupe, l'apprentissage par essais-erreurs, ou encore l'utilisation de nouvelles technologies. Ce texte propose un éclairage sur ces différents points pour ques…
Housing market shocks in italy: A GVAR approach
2020
Abstract In this paper, we use a Global Vector Autoregression (GVAR) model to assess the spatio-temporal mechanism of house price spillovers, also known as “ripple effect”, among 93 Italian provincial housing markets, over the period 2004 − 2016 . In order to better capture the local housing market dynamics, we use data not only on house prices but also on transaction volumes. In particular, we focus on estimating, to what extent, exogenous shocks, interpreted as negative housing demand shocks, arising from 10 Italian regional capitals, impact on their house prices and sales and how these shocks spill over to neighbours housing markets. The negative housing market demand shock hitting the G…
Financial contagion through space-time point processes
2020
AbstractWe propose to study the dynamics of financial contagion by means of a class of point process models employed in the modeling of seismic contagion. The proposal extends network models, recently introduced to model financial contagion, in a space-time point process perspective. The extension helps to improve the assessment of credit risk of an institution, taking into account contagion spillover effects.
The effects of playing tactics on creating scoring opportunities in random matches from US Major League Soccer
2015
The aim of this study was to examine the effects of playing tactics on the creation of scoring opportunities in random matches from US Major League Soccer 2014, taking into account both contextual and defensive variables. The sample included 3253 team possessions corresponding to 30 randomly selected matches. Multidimensional qualitative data from 10 categorical variables was analysed by means of descriptive analysis and multiple logistic regression analysis. Contextual variables such as match location (p=0.049), match half (p=0.043) and match status (P=0.032) were associated with creating scoring opportunities. With regards playing tactics, set plays created a higher proportion of scoring …
