Alfonso V el Magnánimo y el Siti Perillós (1422-1458).

2017

Alfonso V el Magnanimo, Rey de Aragon (1416-1458), constituye un caso excepcional en la representacion del poder politico, ya que personifica el primer monarca europeo en articular un discurso de su imagen en el que conviven y se combinan los valores y modos de representacion medievales con los modernos auspiciados por el Humanismo italiano. Uno de los elementos mas controvertidos e interesantes de dicho discurso lo conforman sus emblemas reales, elementos de tradicion medieval que, precisamente, no solo se mantienen sino que incluso cobran vigor al avanzar el empleo de las formas clasicas. Uno de dichos emblemas es precisamente el que mayor relacion guarda con la tradicion literaria mediev…

Molecular Mobility in Oriented and Unoriented Membranes Based on Poly[2-(Aziridin-1-yl)ethanol]

2021

Unoriented and oriented membranes based on dendronized polymers and copolymers obtained by chemical modification of poly[2-(aziridin-1-yl) ethanol] (PAZE) with the dendron 3,4,5-tris[4-(n-dodecan-1-yloxy)benzyloxy]benzoate were considered. DSC, XRD, CP-MAS NMR and DETA, contribute to characterize the tendency to crystallize, the molecular mobility of the benzyloxy substituent, the dendritic liquid crystalline group and the clearing transition. The orientation of the mesogenic chain somewhat hindered this molecular motion, especially in the full substituted PAZE. The fragility, free volume and thermal expansion coefficients of these membranes near the glass transition are related to the orie…

The Role of Pluriactivity for Continuity and Survival in Family Farm Firms

2014

Our study focuses on family farm firms as an important and yet under-researched type of family firms. We explore the entrepreneurial growth behavior in the context of family farm firms by focusing on the role of pluriactivity. By integrating the literature of family business strategies, EO, and growth intentions, this study of 1618 Finnish family farms seeks to understand the idea of pluriactivity as a strategic orientation of family farm firms leading towards the growth and renewal of their prevailing and future domains. Our study revealed that pluriactivity is associated with growthorientation and perceived strengths of the family farm firms. We identified four types of growth groups (Est…

Block copolymers from ionic liquids for the preparation of thin carbonaceous shells

2017

This paper describes the controlled radical polymerization of an ionic-liquid monomer by RAFT polymerization. This allows the control over the molecular weight of ionic liquid blocks in the range of 8000 and 22000 and of the block-copolymer synthesis. In this work we focus on block copolymers with an anchor block. They can be used to control the formation of TiO2 nanoparticles, which are functionalized thereafter with a block of ionic-liquid polymer. Pyrolysis of these polymer functionalized inorganic nanoparticles leads to TiO2 nanoparticles coated with a thin carbonaceous shell. Such materials may, e.g., be interesting as battery materials.

Stereoselective synthesis of perillaldehyde-based chiral β-amino acid derivatives through conjugate addition of lithium amides.

2014

The Michael addition of dibenzylamine to (+)-tert-butyl perillate (3) and to (+)-tert-butyl phellandrate (6), derived from (S)-(−)-perillaldehyde (1), resulted in diastereomeric β-amino esters 7A–D in a moderately stereospecific reaction in a ratio of 76:17:6:1. After separation of the diastereoisomers, the major product, cis isomer 7A, was quantitatively isomerized to the minor component, trans-amino ester 7D. All four isomers were transformed to the corresponding β-amino acids 10A–D, which are promising building blocks for the synthesis of β-peptides and 1,3-heterocycles in three steps. The steric effects of the isopropyl group at position 4 and of the α-methyl substituent of (R)-N-benzyl…

Amores humanos, amores divinos. La Vita Christi de sor Isabel de Villena

2014

La Vita Christi de Sor Isabel de Villena es un texto de enorme relevancia escrito en la Edad Media. Basado en la Vita Christi de Ludolfo de Sajonia, el Cartujano, puede en realidad interpretarse como una Vita Mariae, pues en él se presta atención particular al papel de la Virgen en la vida de Cristo. Este artículo analiza los paralelos entre esta obra y las prosas mitológicas de Joan Roís de Corella. En los dos puede verse un interés en temas amorosos y en la descripción de los afectos y el mundo interior emocional de los personajes. The Vita Christi by Sor Isabel de Villena is a paramount text written in medieval Iberia. Based on the Vita Christi by Ludolf of Saxony (the Carthusian), the w…

Sobre la filosofia de l’humanista valencià Joan Serra al De contemplatione amicicie. Notes a una traducció catalana

2013

Resum: Presentem la traducció catalana del De contemplatione amicicie, escrit per l’humanista valenciàJoan Serra l’any 1454. La traducció parteix de l’edició curada per Evencio Beltran de l’únic manuscritconegut: BNF ms Nat. lat. 8756. La translació s’acompanya d’una introducció historicofilosòficaarticulada al voltant de l’analogia fonamental de l’obra, a saber, la concòrdia absoluta de dos amicsés com la unió perfecta del cos i de l’ànima humana. S’hi analitzen les fonts fonamentals: Cicerói Pseudo-Agustí, i s’hi constata l’organització dual dels continguts del text, en tant que dedica elscapítols senars a la consideració de la unió del cos i l’ànima segons la filosofia natural, mentre qu…

Pro-inflammatory T helper 17 directly harms oligodendrocytes in neuroinflammation.

2021

Significance Multiple sclerosis (MS) is a neuroinflammatory, demyelinating disease that represents one of the most frequent causes of irreversible disability in young adults. Treatment options to halt disability are limited. We discovered that T helper (Th)17 cells in contact with oligodendrocytes produce higher levels of glutamate and induce significantly greater oligodendrocyte damage than their Th2 counterpart. Blockade of CD29, which is linked to glutamate release pathways and expressed in high levels on Th17 cells, preserved human oligodendrocyte processes from Th17-mediated injury. Our data thus provide evidence for the direct and deleterious attack of Th17 cells on the myelin compart…
