This memoir is divided into two parts, devoted to two topics in (ab-stract) algebraic logic. In the first part we develop a hierarchy in which propositional logics “L” are classified according to the definability conditions ...
This thesis is an investigation into the visualization of cosmological propositions associated with string theory. Research into the work of contemporary theoretical physics led to the question, how does one visualize what ...
[emg] Alternative splicing (AS) is a gene expression regulatory mechanism that enables generation of multiple mRNA isoforms from a single gene which commonly are translated into proteins. This mechanism is tightly regulated ...
Huntington’s Disease (HD) is an autosomal dominant inherited neurodegenerative disorder characterized by motor, psychiatric, and cognitive manifestations. The disease is caused by an unstable expansion of the CAG trinucleotide ...
Environmental constraints and developmental processes in plants can lead to light energy excess in chloroplasts by lowering the threshold at which light becomes saturating by a lack of electron acceptors in the light-processing ...
The main topic of this Thesis is to investigate the contribution of polyamines to defense in Arabidopsis thaliana and the requirement of callose deposition for full expression of effector-triggered immunity in autoimmune ...
[eng] Polyamines are small polycationic molecules that contain amino groups and are found in all living organisms. This study is aimed at acquiring a comprehensive understanding of the diverse roles of polyamines in plants, ...
Heterotrimeric G proteins are masters regulators of cell homeostasis. They coordinate the signaling between G protein coupled receptors (GPCRs) and their intracellular effectors. Heterotrimeric G proteins are composed of ...
The goal of this dissertation is the study and characterisation of high dose Carbon (C) implantation processes into Silicon (Si) and related materials for the synthesis of Silicon Carbide (SiC). The attainment of ...
El objetivo general de esta tesis doctoral ha sido la generación de nuevos modelos celulares para el síndrome de Sanfilippo y su utilización para ensayar una aproximación terapéutica para esta enfermedad basada en el uso ...
Esta tesis, planteada inicialmente como un estudio de comunidad, presenta un estudio de caso sobre relaciones de propiedad en Goizueta; un pueblo euskaldun (vascófono) de unos 700 habitantes situado en el noroeste de ...
The oncogene MYC is altered and its expression is deregulated in up to 70% of human cancers, including B cell neoplasms. Earlier studies in a mouse model of Eμ-MYC-driven B-cell lymphomas reported that oncogenic MYC relies ...
Enmarcada en el estudio de la reacción internacional y la participación extranjera en la guerra civil española, esta Tesis analiza la respuesta al conflicto que se dio en Irlanda. Tal y como ocurrió en el resto de países ...
Iron is an essential micronutrient required for many cellular reactions and a tight regulation of its metabolism is therefore crucial for health. Cellular iron homeostasis relies on the coordination of iron uptake, storage ...
This work is the result of a search for general (or nearly general) regularities at ecosystem level, and an exploration of their practical relevance in our relations with the environment.<br/>I began by adding some new ...
Bacteria and their sub-products are the main cause of the occurrence and perpetuation of endodontic infection. However, only a few bacterial species are seen as responsible of persistent endodontic infections, among them ...
Irrumpir lo artístico, perturbar lo pedagógico: La Investigación Artística como espacio social de producción de conocimiento es una investigación conformada por dos partes: esta tesis y dos vídeos: En colaboración y ...
Els estudis generals realitzats sobre la història de l'art català encara no han profunditzat en la història de l'art local. L'apropament a "quan" i " com" van arribar les avantguardes del Segle XX a Sabadell són una forma ...
El ATP es una molécula ampliamente conocida por su papel en muchas funciones como la homeostasis celular, el mantenimiento de gradientes iónicos, el mantenimiento del pH en gránulos secretores, el almacenamiento energético, ...
Se ha sintetizado la información de las temperaturas de emisión superficial obtenidas mediante 53 imágenes del satélite Terra MODIS, aplicando para ello promedios anuales y estacionales de las temperaturas estandarizadas, ...
