The multiple dimensions of daily travel time: empirical findings in the Barcelona metropolitan region
El temps és el nostre recurs més escàs i, a la vegada, un que a priori es troba igualment limitat per a tots els éssers humans. Una part considerable del nostre temps de vida, aproximadament una hora i mitja al dia, ...
Multiple feature temporal models for the characterization of semantic video contents
La estructura de alto nivel del vídeo se puede obtener a partir de conocimiento sobre el dominio más una representación de los contenidos que proporcione información semántica. En este contexto, las representaciones de la ...
Multiple graph matching and applications
En aplicaciones de reconocimiento de patrones, los grafos con atributos son en gran medida apropiados. Normalmente, los vértices de los grafos representan partes locales de los objetos i las aristas relaciones entre estas ...
Multiple light scattering in atomic media : from metasurfaces to the ultimate refractive index
(English) Our ability to confine, guide, and bend light has led to astonishing technological achievements, playing a fundamental role in diverse fields like microscopy, photochemistry, telecommunications or material design. ...
Multiple simulation experimental studies of gas emission, distribution and migration rules in mine ventilation system and goaf area
Gas problems have created severe difficulties for the mining industry around the world, leading to high expenditures and intensity research efforts, and determined attempts to enhance the various ventilation optimization ...
Multiple stressor effects on river biofilm communities: from community composition to ecosystem processes using experimental mesocosms
Human exploitation of river ecosystems, together with the increasing pressure that represents climate change, is posing rivers worldwide at risk. In rivers, microorganisms are ecologically very important. Most of ...
The Multiple Tasks Endured by PI3K during neural tube development
Development of the spinal cord involves coordination between exposure to localized extracellular signals and controlled activation of intracellular signaling pathways. This way, neuroepithelial cells firstly proliferate ...
Multiplex analysis of circRNAs in lung cancer using the nCounter technology
El càncer de pulmó (CP) és un dels càncers més comunament diagnosticats i la principal causa de mort relacionada amb el càncer a tot el món, principalment degut al seu diagnòstic en estadis tardans i a la manca de tractaments ...
Multiplex optical detection system for prosthetic joint infection diagnosis
La infección de prótesis articular (IPA) es una patología de difícil manejo terapéutico que produce tanto morbilidad física como psicológica en los pacientes afectados y, además, está asociada con un impacto económico ...
Multiplexed detection of SNPs using electrochemical melting curve analysis
L'objectiu general d'aquesta tesi doctoral és desenvolupar plataformes de geno-sensors de baix cost per a la detecció múltiple de polimorfismes d'un sol nucleòtid. La determinació de polimorfismes d'un sol nucleòtid (SNP) ...
A Multiplexed diagnostic approach for cardiovascular disease biomarkers
In the course of this thesis, the optimal epitopes for the subsequent polyclonal rabbit antibody production for cTnI and NT-proBNP have been studied and chosen. cTnI and NT-proBNP are the most relevant cardio-specific ...
Multiplicación en estado integrado y efecto protector frente a la irradiación ultravioleta del factor S de citrobacter intermedium C3
La interacción entre los hechos y las ideas ha caracterizado el continuo progreso científico de los últimos cuatro siglos. En biología esta interacción se hace aún más patente, dado que la naturaleza compleja de ...
Multiplier ideals in two-dimensional local rings with rational singularities
The aim of this memoir is to study multiplier ideals in two-dimensional local rings having at worst rational singularities. We also want to extend this study to the case of mixed multiplier ideals. The main achievements ...
Multirate mass transfer and biofilm growth modeling in porous media
Reactive transport modeling is a methodological tool to study the coupled physical, chemical and biological processes in Earth system. It is complex not only because of the nature of the equations, but also because of the ...
Multiregional sustainability at a sectoral level: Towards more effective environmental regulations
Aquesta tesi està dedicada al desenvolupament d'eines per ajudar als responsables polítics en la creació de normatives eficaces de manera eficient i metòdica. La tesi està organitzada en quatre seccions principals. A la ...
Multiresolution image segmentation based on camporend random fields: Application to image coding
La segmentación de imágenes es una técnica que tiene como finalidad dividir una imagen en un conjunto de regiones, asignando a cada objeto en la escena una o varias regiones. Para obtener una segmentación correcta, cada ...
Multiscalar strategies for the characterization of engineered P450 enzymes
Enzymes are a type of proteins that help chemical reactions happen faster in living organisms. Scientists have been able to modify these enzymes using a technique called protein engineering, which allowed to increase the ...
Multiscale behavior in living systems
This thesis focuses on the multiscale nature of the biological process that underpin the function of all living systems. A first project centers on the disease known as multiple sclerosis, and utilizes various datasets at ...
Multiscale cardiovascular analysis and simulations for the understanding of intra-uterine cardiovascular remodelling
Cardiovascular diseases are nowadays one of the major causes of death in developed countries. Besides the already known risk factors such as lifestyle and genetics, there is a growing evidence that adverse remodelling ...
Multiscale characterization of cardiac remodeling induced by intrauterine growth restriction, at organ, cellular and subcellular level
INTRODUCTION: Intrauterine growth restriction (IUGR) due to placental insufficiency affects up to 7-10% of pregnancies and is a major cause of perinatal mortality and long term morbidity. IUGR results in low birth weight, ...
