L’esteatohepatitis no alcohòlica (NASH) és un trastorn hepàtic crònic comú als països desenvolupats, conseqüència de l’acumulació excessiva de lípids en els hepatòcits i associat a les complicacions clíniques provocades ...
Pujol Payet, Isabel (Data de defensa: 2001-02-26)
Esta tesis se centra en el estudio de la evolución de los derivados de origen numeral desde el latín hasta la actualidad. Nuestro objetivo principal es doble: por un lado, pretendemos descubrir si este conjunto de elementos ...
Mora Acosta, Josue (Data de defensa: 2001-12-20)
The target of this work is to contribute to the enhancement of numerical methods for the simulation of complex thermal systems. Frequently, the factor that limits the accuracy of the simulations is the computing power: ...
Sadurní Caballol, Alexandre (Data de defensa: 2012-09-28)
The aim of this work is to study the thermal behavior and fluid-dynamic systems, vapor compression refrigeration and its components (heat exchangers, expansion devices, compressors, connecting pipes, pumps and pressure ...
Albareda Valls, Albert (Data de defensa: 2013-01-18)
Concrete-filled tubes have been increasingly used these recent decades thanks to their improved structural behavior, especially under compression.Concrete filling in these sections improves ¡ts compressive strength thanks ...
Casas González, Guillermo (Data de defensa: 2018-10-30)
In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a multi-component) problem, ...
Irazábal González, Joaquín (Data de defensa: 2017-10-06)
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were constructed using ...
Blanch Ojea, Roland (Data de defensa: 2011-12-19)
Aquesta tesi centra els seus esforços en l'àmbit de la microfluídica, un camp relativament recent dins de la Mecànica de Fluids, amb un futur prometedor i amb un ritme d'investigació intens en les seves diferents ...
Serra López, Roger (Data de defensa: 2018-05-22)
Structural health monitoring has been defined as the acquisition, validation and analysis of technical data to facilitate life- cycle management decisions. It is the result of a convergent path from many previous existing ...
Kessentini, Hamdi (Data de defensa: 2014-02-14)
In this thesis a flat plate collector (FPC) with plastic transparent insulation materials (TIM) and a low-cost overheating protection system destined for heat supply from 80 to 120°C is presented. A ventilation channel ...
Cito, Salvatore (Data de defensa: 2009-12-15)
Micro-channels are believed to open up the prospect of precise control of fluid flow and chemical reactions. The capillary effect can be used to pump fluids in micro-channels and the flow generated can dissolve chemicals ...
Biosca Mecías, Adrià (Data de defensa: 2020-01-10)
El disseny del motlle preparador és un punt crític en el desenvolupament de nous flascons ja que defineix la distribució d’espessors de vidre en les ampolles fabricades. Tot i això, el disseny d’aquestes cavitats encara ...
Bassit Megalaa, Gorg Abdelmassih (Data de defensa: 2016-09-12)
En aquest estudi s'analitzen els experiments i simulacions numèriques del flux de convecció mixta en una cavitat cúbica situada a la part inferior d'un canal quadrat. Els nombres de Reynolds en funció de la velocitat mitjana ...
