Mecanismos para la ampliación del parque público de vivienda. Entre el urbanismo y la colaboración público-privada
[spa] El artículo 47 de la Constitución señala la obligación que tienen los poderes públicos de garantizar el derecho a una vivienda digna y adecuada. La Administración, en especial las Comunidades Autónomas (pues ostentan ...
Mecanismos y consecuencias clínicas de los patrones electrocardiográficos de infarto agudo de miocardio con bloqueo de rama izquierda del haz de His
El diagnòstic d’infart de miocardi en presència de bloqueig de branca esquerra del feix de His (BBEFH) és un repte per al clínic, donat que els canvis electrocardiogràfics intrínsecs al propi trastorno de la conducció basal ...
Mecànica Relativista Predictiva. Electrodinàmica i lagrangians singulars
A la relativitat, a diferència de la mecànica newtoniana, no trobem exemples senzills de sistemes dinàmics de diverses partícules. La formulació covariant Lorentz de les equacions del moviment per a sistemes de partícules ...
Mecànismes patogènics en l'Esclerosi Lateral Amiotròfica humana i experimental
En aquest estudi s'ha treballat amb diferents hipòtesis que avui en dia es consideren per explicar les causes de l'Esclerosi Lateral Amiotròfica.<br/><br/>En primer lloc, s'ha estudiat la autoimmunitat sèriques (IgG) ...
Mechanical and electromechanical properties of ferroelectrics at the nanoscale studied by Atomic Force Microscopy
La microscòpia de força piezoresposta (PFM) és una eina poderosa per a la caracterització electromecànica de materials ferroelèctrics. En aquest mode de microscòpia de força atòmica (AFM), una tensió de corrent alterna ...
Mechanical and functional properties in magnetic materials
This doctoral Thesis has been focused on the preparation of magnetic materials by different methods, the characterization of their structural characteristics, and the understanding of their mechanical and magnetic properties. ...
Mechanical and thermal stability of hard nitride coatings
Hard coating 's thermal stability is essential due to the high temperature environment of high-speed cutting applications, while the induced phase and microstructure evolution affects the mechanical properties. In this ...
Mechanical behaviour of tools for shearing Ultra High-Strength Steels: influence of the microstructure on fracture and fatigue micro-mechanisms of tool steels and evaluation of micro-mechanical damage in tools
On account of environmental and safety related requirements, the majority of the most popular automotive manufacturers convey to introduce Ultra High Strength Steels (UHSS) and Press Hardened Steels (PHS) in the vehicle ...
Mechanical characterisation of masonry in existing structures by means of laboratory and in-situ experimental techniques
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
Mechanical control of epithelial tissue formation and function in early development
The outer epithelial layer is the first cell type that emerges during development, providing essential mechanical protection and is indispensable for morphogenesis. Here, we study how the interplay between molecular and ...
Mechanical control of nuclear plasticity and mechanotransduction in cell migration
Cells commonly live in a crowded environment, in a tissue or in a developing embryo. The extracellular matrix and/or surrounding neighboring cells can impose physical deformations to which cells need to adapt in order to ...
Mechanical instabilities and dynamics of living matter. From single-cell motility to collective cell migration
The thesis belongs to the field of biophysicis, in particular we evaluate from a physicial perspective biological processes that occur at the celular and multicelular scales involving collective phenomena of self-organization. ...
Mechanical performance and sustainability assessment of reinforced soil walls
Soil reinforced retaining wall structures are materiallymore efficientthan competing construction solutions such as gravity and cantilever walls. Nevertheless, the behaviour and interactions between the com ponent materials ...
Mechanical properties of co-doped zirconia ceramics
Tetragonal polycrystalline zirconia, commonly stabilised with 3 mol% yttria (3Y-TZP), became one of the most interesting ceramics for biomedical applications due to its biocompatibility and high mechanical properties. Among ...
Mechanical Properties of HTSC at Micro/Nanometric Scale
The nanoindentation or indenter testing technique (ITT) is a functional and fast technique that can give us a lot of information about the mechanical properties of different materials at nanometric scale, from soft to ...
Mechanical resistance to fracture of narrow platform dental implants with hexagonal external connection submitted to implantoplasty with different bone levels and crown/implant ratios. An in vitro study.
[eng] INTRODUCTION: Peri-implantitis is an inflammatory condition that affects soft and hard tissues around dental implants and that can lead to implant failure. Implantoplasty is a procedure that allows implant surface ...
Mechanical resonators based on graphene and carbon nanotubes
Los resonadores mecánicos basados en grafeno y nanotubos de carbono han atraído recientemente una considerable atención, debido a la gran variedad de propiedades extraordinarias que exhiben. La reducida dimensión intrínseca ...
Mechanical stress in curved epithelia of designed size and shape
GENERAL AIM: The general aim of this thesis is to understand how mechanical stress depends on pressure, size and shape in fluid-filled curved epithelial sheets. SPECIFIC AIMS: This general aim can be divided ...
Mechanics and Cellular Mechanisms Driving Zebrafish Epiboly = Mecánica y mecanismos celulares responsables de la epibolia del pez cebra
Epithelial layers constitute the skeleton of early embryos and most tissues and organs and their remodelling during development is essential for reshaping the embryo and for tissue architecture. Epithelial expansion in ...
