Tail and Head Group Interactions in Phospholipid Monolayers
1996
Abstract The order/disorder transition of the phospholipid 1,2-dihexadecyl-sn-glycero-3-phosphocholine and its derivatives was studied by X-ray reflection and thermodynamic measurements. We find that increasing the length of an ethylene oxide spacer (zero to three EO groups) between the phosphate group and the hydrophobic chains (i) induces a slight shift of the main transition, (ii) reduces the influence of the head groups on the chain lattice, and (iii) increases the head group length and promotes its hydration. For DH(EO)3PC in the ordered phase we find that the small phosphate groups (which are the main source of contrast in X-ray reflectivity) are homogeneously distributed within the h…
Effect of 1-methylcyclopropene on ripening of melting flesh peaches and nectarines
2004
Abstract 1-Methylcyclopropene (1-MCP), an ethylene action inhibitor, was applied to early season, melting flesh stone fruit to try to extend their shelf life. ‘Almog’ and ‘Oded’, two white flesh peaches, and ‘April Glow’, a yellow flesh nectarine, were tested. Application of 1-MCP was at both 20 and 0 °C for 5, 10 and 20 h and at concentrations from 0.5 to 20 μl l −1 . When treated at 0 °C the fruits were stored for 5 days before removal to 20 °C for ripening. 1-MCP slowed fruit softening in a concentration and time dependent manner, extending the period before the fruits became over-soft. The inhibition of softening was greater when fruits were treated and held at 20 °C than if they were t…

Evaluating the extent of patient-centred care in a selection of ESC guidelines
2019
AIMS: Patient-centred care (PCC) is the cornerstone for healthcare professionals to promote high quality care for patients with cardiovascular conditions. It is defined as 'Providing care that is respectful of, and responsive to, individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions'. PCC can improve patient outcomes and allow patients and healthcare professionals to manage care collaboratively using best available evidence. However, there is no clear understanding how extensively guidelines incorporate PCC recommendations. The aim of the study was to evaluate the incorporation of PCC into a selection of guidelines published by the E…
The Economics of Monetary Union: The Theory of Optimum Currency Areas
2013
In the 1960s, the theory of Optimum Currency Areas (OCAs) emerged as a by-product of the theoretical debate between fixed and flexible exchange rates. The OCAs approach singles out an economic characteristic to define an economic domain where there is exchange rate fixity erga intra, while there is exchange rate flexibility erga extra. In an optimum currency area, exchange rates fixity prevails internally without any type of internal or external disequilibrium. Each single characteristic ensures that floating or regular adjustments in nominal exchange rates are neither necessary, efficient nor desirable for stabilisation purposes. The literature proposes several economic criteria: factor mo…

Alterations in the Microstructure of the Anterior Mitral Valve Leaflet Under Physiological Stress
2012
An improved understanding of mitral valve (MV) function remains an important goal for determining mechanisms underlying valve disease and for developing novel therapies. Critical to heart valve tissue homeostasis is the valvular interstitial cells (VICs), which reside in the interstitium and maintain the extracellular matrix (ECM) through both protein synthesis and enzymatic degradation [1]. There is scant quantitative experimental data on the alterations of the MV fiber network reorganization as a function of load, which is critical for implementation of computational strategies that attempt to link this meso-micro scale phenomenon. The observed large scale deformations experienced by VICs…
Firing characteristics of vestibular nuclei neurons in the alert monkey after bilateral vestibular neurectomy
1992
After destruction of the peripheral vestibular system which is not activated by moving large-field visual stimulation, not only labyrinthine-ocular reflexes but also optokinetic-ocular responses related to the "velocity storage" mechanism are abolished. In the normal monkey optokinetic-ocular responses are reflected in sustained activity changes of central vestibular neurons within the vestibular nuclei. To account for the loss of optokinetic responses after labyrinthectomy, inactivation of central vestibular neurons consequent on the loss of primary vestibular activity is assumed to be of major importance. To test this hypothesis we recorded the neural activity within the vestibular nuclea…
Direct validation of FVC, LAI and FAPAR VEGETATION/SPOT derived products using LSA SAF methodology
2007
The aim of this work is to perform a direct validation of fraction of vegetation cover (FVC), leaf area index (LAI) and fraction of absorbed photosynthetically active radiation (FAPAR) resulting products from applying the LSA SAF methodology to VEGETATION BRDF data. LSA SAF adapted algorithms were tested in adequate test sites comprising different continental biomes covering a wide range of FVC, LAI and FAPAR values. Results seem to indicate the competitiveness of LSA SAF proposed methodology to retrieve remotely sensed biophysical parameters. A noticeable good agreement regarding the ground measurements was found. The overall accuracy (RAISE) is around 20% for FVC and FAPAR and around 15% …
De la pertinence de l'adjectif "étrangère" en Didactique des Langues-Cultures
2012
Les statuts traditionnellement attribués aux langues (ancienne/moderne, morte/vivante, maternelle/étrangère) continuent de remplir leurs fonctions : opposer, ordonner, identifier acteurs et spécialistes de chaque domaine. De leur côté, « Français Langue Etrangère » et « FLE », après des débuts difficiles, connaissent un succès tel que l’on oublie les idées qu’ils véhiculent et leur adaptation nécessaire à une diversité linguistique et culturelle croissante. Dans le contexte de l’apprentissage effectif et durable des langues-cultures du monde, impossible sans processus de familiarisation, la pertinence de l’adjectif « étrangère » est discutable. Accorder une valeur maximale aux qualificatifs…
