Da poeta a poeta, da traduttore a traduttore: il carteggio tra Umberto Saba e Tomàs Garcés
2015
Riassunto: Il rapporto personale tra Umberto Saba e Tomàs Garcés cominciò agli inizi degli anni Trenta e si interruppe poco prima della guerra civile spagnola. Quest’articolo analizza ed edita per la prima volta tutte le lettere scritte da Saba al poeta catalano che sono state conservate presso l’archivio della famiglia Garcés. Parole chiave: poesia, traduzione, Umberto Saba, Tomàs Garcés Abstract: The personal relationship between Umberto Saba and Tomàs Garcés began in the early thirties and stopped just before the Spanish Civil War. This article analyses and edits for the first time all the letters written by Saba to the Catalan poet that have been preserved in the archives of f…

A critical perspective on Integrated Project Delivery (IPD) applied in a Norwegian public hospital project
2020
Does the IPD concept deliver as required and expected, and if not, how can that be explained? This paper is a critical realist inspired methodology based on a combination of the inductive and deductive approaches used in case study research. IPD is based on relational contracting between multiple parties, in this case between the Owner, Contractor, MEP subcontractors and a group of Consulting engineers who share control of the project. At the core of the concept is shared risk and opportunities among the parties in the IPD contract. Our theoretical perspectives are based mainly on the Principal-Agent theory (PA), Transaction Cost theory (TC), and its related incentives. This paper reports o…
Transcription, apoptosis and p53: catch-22
2005
The tumor suppressor p53 is a transcription factor and is activated in response to DNA damage or oncogenic transformation through modification of its interaction with regulatory proteins. The transcription factor activity of p53 is thought to mediate its primary functions of cell-cycle arrest and apoptosis through the gene expression it regulates, and evidence to support this interpretation continues to accumulate. However, reports of transcription-independent activities of p53, especially in the induction of apoptosis, persist. In particular, recent studies suggest that cytosolic p53 directly interacts with members of the BCL-2 family of apoptosis regulators, thereby triggering mitochondri…
Estimación mediante teledetección de la evapotranspiración real a partir de un modelo desacoplado de dos fuentes
2007
RESUMEN En esta Tesis se propone un modelo simplificado de balance de energía de dos fuentes (STSEB) para el cálculo de los flujos energéticos en superficie, cuya principal característica es que los flujos de cada una de las fuentes se consideran totalmente desacoplados. La clave del modelo es la ponderación que se hace de las contribuciones de cada fuente, a cada uno de los flujos totales del sistema, a través de sus respectivas áreas parciales de ocupación. El modelo STSEB incluye, además, un nuevo esquema simplificado de distribución de la radiación neta total entre las componentes del suelo y de la vegetación. Como alternativa al uso de ecuaciones empíricas adicionales, se propone medir…
Transverse instability of periodic and generalized solitary waves for a fifth-order KP model
2017
We consider a fifth-order Kadomtsev-Petviashvili equation which arises as a two-dimensional model in the classical water-wave problem. This equation possesses a family of generalized line solitary waves which decay exponentially to periodic waves at infinity. We prove that these solitary waves are transversely spectrally unstable and that this instability is induced by the transverse instability of the periodic tails. We rely upon a detailed spectral analysis of some suitably chosen linear operators.
Push‐Pull Design of Bis(tridentate) Ruthenium(II) Polypyridine Chromophores as Deep Red Light Emitters in Light‐Emitting Electrochemical Cells
2013
Light-emitting electrochemical cells (LECs) with a simple device structure were prepared by using heteroleptic bis(tridentate) ruthenium(II) complexes [1](PF6)(2)-[3](PF6)(2) as emitters. The push-pull substitution shifts the emission energy to low energy, into the NIR region. The devices emit deep red light up to a maximum emission wavelength of 755 nm [CIE (International Commission on Illumination) coordinates: x = 0.731, y = 0.269 for [3](PF6)(2)], which, to the best of our knowledge, is the lowest emission energy for LECs containing bis(tridentate) ruthenium(II) complexes. A device structure of ITO/PEDOT:PSS/ruthenium(II) complex/Ag was used, and the thickness of the emitting layer was …
Analysis of p53 and mdm2 proteins in malignant fibrous histiocytoma in absence of gene alteration: prognostic significance.
2000
TP53 and MDM2 genes and their protein expression were evaluated in frozen and paraffin-embedded tissue from 27 patients with malignant fibrous histiocytoma to elucidate the relationship between them, their implication in tumor progression mechanisms and their possible diagnostic-prognostic value in malignant fibrous histiocytoma. Single-strand conformation polymorphism analysis and direct sequencing of polymerase chain reaction-amplified DNA were used to establish two TP53 mutations (7.4%): a point mutation and a 63-bp duplication. Amplification of the MDM2 gene was observed in two tumors (7.4%) by means of Southern-blot analysis, one of them also carrying the TP53 point mutation. Immunohis…
