Printing Life-Inspired Subcellular Scale Compartments with Autonomous Molecularly Crowded Confinement.
2019
A simple, rapid, and highly controlled platform to prepare life-inspired subcellular scale compartments by inkjet printing has been developed. These compartments consist of fL-scale aqueous droplets (few µm in diameter) incorporating biologically relevant molecular entities with programmed composition and concentration. These droplets are ink-jetted in nL mineral oil drop arrays allowing for lab-on-chip studies by fluorescence microscopy and fluorescence life time imaging. Once formed, fL-droplets are stable for several hours, thus giving the possibility of readily analyze molecular reactions and their kinetics and to verify molecular behavior and intermolecular interactions. Here, this pla…
New solutions of preparation and activation of surfaces
2017
Organic coatings applied on the surface of cast iron pipes ensure very good chemical and anti-corrosion protection against aggressive effluents. To improve adherence between coating (epoxy) and substrate, a surface preparation is required. Among conventional processes shot blasting has emerged as the most efficient and cheapest solution for ensuring stripping while generating adapted roughness. However, as it may enhance both mechanical anchorage and chemical bonding a better understanding of these phenomena should be developed. Besides new eco-friendly alternatives were investigated.Indeed, new techniques were evaluated, i.e. laser structuring and an ultra-high pressure water jet whose maj…
La comprensión e impulso de la Sostenibilidad: un requisito imprescindible para una acción educativa y ciudadana eficaz
2019
Diagnósticos concordantes de la actual situación de emergencia planetaria muestran la necesidad de una urgente transición a sociedades que hagan posible una vida justa y digna al conjunto de seres humanos y a las futuras generaciones, al tiempo que se protege la biodiversidad y se revierte la degradación del medioambiente. Esta problemática ha dado lugar a propuestas con distintas denominaciones -transición a la sostenibilidad, decrecimiento, crecimiento inclusivo… - generando controversias que pueden dificultar el establecimiento de una agenda común para hacer frente a los problemas. Proponemos por ello centrar el debate en analizar las medidas que se consideran necesarias, en particular p…
Physical Parameters in Relativistic Jets from Compact Symmetric Objects
2001
Compact symmetric objects (CSOs) conform a class of sources characterized by high luminosity radio emission located symmetrically on both sides of the active galactic nucleus on linear scales of less than 1 kpc. Given their small size, the hot spots of the jets in CSOs provide a unique laboratory for the study of the physics of relativistic jets and their environment close to the central engine. We present a simple model for the hot spots in CSOs assuming synchrotron emission, minimum energy and ram-pressure equilibrium with the external medium. Further comparison of our model with observational data allows us to constrain the physical parameters in the hot spots and the jets feeding them, …
Search for promptly produced heavy quarkonium states in hadronic Z decays
1996
A search has been made for direct production of heavy quarkonium states in more than 3 million hadronic Z^{0} decays in the 1991-1994 DELPHI data. Prompt J/\psi, \psi(2S) and \Upsilon candidates have been searched for through their leptonic decay modes using criteria based on the kinematics and decay vertex positions. New upper limits are set at the 90 \% confidence level for {Br( Z^0 \rightarrow \left( Q \bar{Q} \right) X ) / Br( Z^0 \rightarrow \mbox{hadrons})} for various strong production mechanisms of J/\psi and \Upsilon; these range down to 0.9 \times 10^{-4}. The limits are set in the presence of a small excess (\sim 1 \% statistical probability of a background fluctuation) in the su…
Overview of the JET results in support to ITER
2017
The 2014–2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials successfully took place since its installation in 2011. New multi-machine scaling of the type I-ELM divertor energy flux density to ITER is supported by first principle modelling. ITER relevant disruption experiments and first principle modelling are reported with a set of three disruption mitigation valves mimicking the ITER setup. Insights of the L–H power threshold in Deuterium and Hydrogen are given, stressing the importance of the magnetic configurations and the recent m…
Effectiveness of interceptive treatment of class III malocclusions with skeletal anchorage: A systematic review and meta-analysis
2017
Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made in the Pubmed, Embase, Scopus and Cochrane databases, as well as in a grey literature database, and were complemented by hand-searching. The criteria for eligibility were: patients who had undergone orthodontic treatment with skeletal anchorage (miniplates and miniscrews). Patients with syndromes or …
La construcción de subjetividades en el Tercer Sector: aproximación a las Empresas de Inserción en el marco del Capitalismo Flexible
2016
El presente trabajo de Tesis Doctoral pretende realizar una aproximación a las Empresas de Inserción, sus prácticas, lógicas y efectos en el marco de las entidades del Tercer Sector. El objetivo que perseguimos al aproximarnos a las Empresas de Inserción es describir su situación en la sociedad actual atendiendo al papel que juegan las entidades en la construcción de subjetividades. Hacerlo posibilitará la comprensión y el análisis de las prácticas concretas que se desarrollan en las Empresas de Inserción, así como la comprensión y análisis de las lógicas seguidas por las entidades que las desarrollan. Para contextualizar el análisis emplearemos los desarrollos teóricos y metodológicos de L…
Impact du contexte scolaire dans l'élaboration des choix d'études supérieures des élèves de terminale
2005
International audience; Si à l'issue de la classe de terminale générale et technologique, les projets d'études supérieures des jeunes varient selon le degré de réussite, la série du baccalauréat, le milieu social ou le genre, ils ne sont pas non plus indépendants des caractéristiques de l'établissement. Les souhaits d'orientation en CPGE sont toujours plus fréquents quand l'élève est scolarisé dans un lycée à recrutement social favorisé ou ayant une offre de classe préparatoire dans l'établissement. D'une manière plus générale, c'est l'ensemble des projets d'études supérieures des jeunes qui apparaissent sensibles à la composition sociale de l'établissement : à résultats scolaires et milieu…
