Physicochemical Properties of A New PEGylated Polybenzofulvene Brush for Drug Encapsulation
2019
A new polymer brush was synthesized by spontaneous polymerization of benzofulvene macromonomer 6-MOEG-9-T-BF3k bearing a nona(ethylene glycol) side chain linked to the 3-phenylindene scaffold by means of a triazole heterocycle. The polymer structure was studied by SEC-MALS, NMR spectroscopy, and MALDI-TOF MS techniques, and the results supported the role of oligomeric initiatory species in the spontaneous polymerization of polybenzofulvene derivatives. The aggregation features of high molecular weight poly-6-MOEG-9-T-BF3k-FE were investigated by pyrene fluorescence analysis, dynamic light scattering studies, and transmission electron microscopy, which suggested a tendency towards the format…
El sexo, el contexto familiar y la actividad física extraescolar como factores asociados a la coordinación motriz en la niñez. Un estudio piloto. [Ge…
2019
Existen diversos factores que determinan el desarrollo y la evolución de la coordinación motriz. El presente estudio tiene por objetivo analizar la influencia del sexo, la actividad física practicada por los padres, la existencia de hermanos/as mayores o de igual edad y la práctica de actividad física extraescolar sobre el nivel de coordinación motriz global. La muestra estuvo compuesta por 23 niñas y 32 niños de entre 8-9 años (M = 8,51; DT = 0,31), pertenecientes al tercer curso de Educación Primaria. El nivel de coordinación motriz global de los estudiantes se valoró a través del Test Motor GRAMI-2 (Ruiz, Rioja, Graupera, Palomo, y García, 2015). El análisis de regresión lineal múltiple …
El pensamiento del alumnado inactivo sobre sus experiencias negativas en educación física: los discursos del rendimiento, salutismo y masculinidad he…
2019
El propósito de este estudio es el análisis del pensamiento de los estudiantes inactivos sobre sus experiencias negativas en educación física y los discursos sociales asociados a ellas. Siete estudiantes de Bachillerato, cuatro chicos y tres chicas, clasificados como inactivos en una fase de investigación cuantitativa previa, participaron en entrevistas semiestructuradas. Cuatro temas resultaron del análisis temático de las experiencias negativas contadas por el alumnado. El primero mostraba cómo los estudiantes inactivos sufren las consecuencias de unas clases y evaluación orientadas por el profesorado hacia el rendimiento físico, especialmente los chicos obesos y las chicas con baja compe…
Resonance in Interacting Induced-Dipole Polarizing Force Fields: Application to Force-Field Derivatives
2009
The Silberstein model of the molecular polarizability of diatomic molecules, generalized by Applequist et al. for polyatomic molecules, is analyzed. The atoms are regarded as isotropically polarizable points located at their nuclei, interacting via the fields of their induced dipoles. The use of additive values for atom polarizabilities gives poor results, in some cases leading to artificial predictions of absorption bands. The molecular polarizability of methane and its derivative are computed. The agreement with experimental mean molecular polarizabilities is within 1–5%. A hypothesis is indispensable for a suitable representation of polarizability derivative.
E-maintenance platform: a business process modelling approach
2014
Las tecnologías de la información y la comunicación (TIC) se utilizan cada vez más en la sociedad y en los negocios. Las TIC se han convertido en un elemento clave para el desarrollo empresarial y la mejora de las actividades en todos los departamentos de una organización. Análogamente, la creciente importancia de los Sistemas de Gestión de Mantenimiento asistido por Ordenador (CMMS), Mantenimiento Basado en la Condición (CBM), y la aplicación de dispositivos remotos y funciones como el e-mantenimiento, han abierto grandes posibilidades para la optimización del mantenimiento. Estas técnicas han dado lugar a la aparición de retos tecnológicos, tales como la interoperabilidad entre diferentes…
Wo3 and ionic liquids: A synergic pair for pollutant gas sensing and desulfurization
2020
This review deals with the notable results obtained by the synergy between ionic liquids (ILs) and WO3 in the field of pollutant gas sensing and sulfur removal pretreatment of fuels. Starting from the known characteristics of tungsten trioxide as catalytic material, many authors have proposed the use of ionic liquids in order to both direct WO3 production towards controllable nanostructures (nanorods, nanospheres, etc.) and to modify the metal oxide structure (incorporating ILs) in order to increase the gas adsorption ability and, thus, the catalytic efficiency. Moreover, ionic liquids are able to highly disperse WO3 in composites, thus enhancing the contact surface and the catalytic abilit…
Vascularized composite allotransplantation - a Council of Europe position paper
2017
After more than 120 hand-upper extremity and 37 face transplant procedures performed worldwide, vascularized composite allotransplantation (VCA) now falls under the scope of organ transplant legislation in Europe and the United States. While in the USA, VCA has been considered as standard care since 2014, VCA in Europe is still performed through clinical research trials, except in United Kingdom. However, after two decades of favourable experience with upper extremity transplantation (UET), professionals in Europe are proposing hand allotransplantation as “controlled standard” care, as opposed to face transplantation (FT), which is still a challenging activity. The European Committee on Org…
White Paper on Governance: EU Attempt to Popularize Legal Discourse?
2015
Since the 1990s the discourse on the relationship between the EU institutions and member states in the field of European action has changed significantly and it has been increasingly supplemented by framework agreements between the actors involved in the Community dialogue. In this regard, the White Paper on Governance (Brussels, 25.7.2001 - COM(2001) 428final) contains a series of recommendations on how to enhance democracy in Europe and boost the legitimacy of the institutions. The aim is to modernize European public action in order to increase the accountability of European executive bodies to the elected assemblies and open up the Union's decision-making procedures to allow citizens to …
Ian T. Benson, Michael Quinlan e Keith Thompson, Religious Freedom in Australia – A new Terra nullius, Shepherd Street Press, Sydney, 2019, pp. 1-370.
2019
Il volume offre un interessante e attuale spaccato giuridico, sociologico e culturale sulla regolamentazione del diritto di libertà religiosa in Australia, consentendo una riflessione sulle principali problematiche concernenti la tutela di tale fondamentale diritto in questa parte dell’Oceania. Il libro, formato da una raccolta di scritti di autori vari, è strutturalmente suddiviso in tre distinte sezioni ottimamente collegate tra di loro dalla comune matrice strutturale costituita dall’intenzione di fornire la “big picture” delle garanzie normative e politiche della “religious liberty” in Australia.
