Disentangling the formation path of lenticular galaxies
[eng] Astronomers have known of the existence of lenticular galaxies (S0) almost as long as they have known that there are other galaxies besides the Milky Way. While it is accepted that spiral galaxies emerge from the ...
Improving the Reliability of Conductive Atomic Force Microscopy
[eng] Owing to its exceptional topographical resolution and electrical sensitivity, Conductive Atomic Force Microscopy (C AFM) has become an essential tool for nanoscale material analysis. However, achieving reproducible ...
Development of microfluidic devices for cancer cell isolation
[eng] The emergence of liquid biopsies has been useful for the diagnosis of physiological conditions, inflammatory processes, and especially represents a good alternative tool for non-invasive analysis of tumor-derived ...
Development of opto-mechanical sensors based on silicon nanopillars for biological applications
[eng] The scope of this thesis is the advancement on the theoretical simulation and nanofabrication of photonic crystals based on a periodic array of silicon pillars. This research is intended to be part of the preliminary ...
Towards a non-perturbative description of cosmological inflation
[eng] From the observation of the cosmic microwave background radiation (CMBR) we know that the universe is isotropic on scales larger than ∼ 75 Megaparsec to at least one part in 100000. The leading paradigm for explaining ...
Coherent Flux Qubits for Quantum Annealing
[eng] Quantum annealing is a heuristic analog quantum algorithm that promises potential quantum speedup over classical algorithms for a huge variety of optimization problems. Current existing annealers, despite their ...
Dynamical and Mechanical Characterisation of Bi- and Tri-dimensional Neuronal Cultures: from Health to Disease
[eng] In this PhD thesis, we leverage the well established foundations of complex systems physics and integrate insights from medicine and materials engineering to advance our understanding of neuroscience. Our primary ...
Os arquivos como “Actor-Rede” na relação com as controvérsias do social através da produção audiovisual em educação superior
[spa] A partir de un movimiento inicial marcado por una experiencia docente involucrada con las controversias de un contexto social específico (Alentejo - Portugal), la posibilidad de interactuar con un espacio en ruinas ...
Colloidal dynamics in artificial particle ice systems
[eng] Geometrical frustration is a general phenomenon influencing the behavior of diverse natural systems across different length scales. Geometrical frustration arises when the symmetry of the interaction among building ...
La clase mutante. Una investigación sobre los movimientos que tienen lugar cuando la práctica escénica entra a formar parte de las relaciones pedagógicas y la atención a la diversidad en la Educación Secundaria Obligatoria
[spa] Esta investigación adapta y aplica la práctica escénica al contexto de la Educación Secundaria Obligatoria, preguntándose por su potencial a la hora de reconfigurar las relaciones pedagógicas y de cuidado así como ...
Embalses, Acequias, Depuradoras. Patrones de producción en la práctica escultórica, las materias primas y la naturaleza.
[spa] Esta tesis presenta tres infraestructuras hídricas: un embalse, una acequia y una depuradora. En ellas se discute un grupo de patrones, a partir de los cuales relaciono las dinámicas de transformación de la naturaleza, ...
Complicaciones de los dispositivos venosos y factores de riesgo de bacteriemia asociada a catéter en el paciente portador de dispositivo venoso central o de midline
[spa] La colocación de dispositivos venosos son el procedimiento invasivo más prevalente en las instituciones hospitalarias tanto en contextos de hospitalización convencional como en hospitalización domiciliaria. A pesar ...
Decadal climate prediction and predictability for climate services
[eng] Climate variations at annual to decadal time scales affect many regions around the globe, causing direct impacts on the economy, ecosystems and society. Knowing these variations in advance allows for implementing ...
Active turbulence and active shell models for microswimmer suspensions
[eng] This doctoral thesis deals with the study of the collective behavior of active particles using computacional simulations of semi-dilute solutions of microswimmers. Results are obtained for the polar order parameter, ...
Study of the components and adherence to the Mediterranean diet on functional and cognitive ageing: from dietary assessment to a metabolomic approach
[eng] Healthy dietary patterns, such as the Mediterranean diet, have been linked to reduced chronic disease risk and mortality. However, the evidence regarding the impact of healthy dietary patterns on physical and cognitive ...
Beyond the current tobacco control legislation. Do europeans support further policies? Attitudes and associated factors
[eng] BACKGROUND. The consumption of tobacco products kills 810,000 Europeans per year. Although significant accomplishments were made since the recognition of the tobacco epidemic, public health still faces challenges to ...
Development and applications of photoswitchable ligands for G protein-coupled receptors
[eng] G protein-coupled receptors (GPCRs) modulate diverse cellular responses to the majority of neurotransmitters and hormones within the human body. They exhibit much structural and functional diversity and are responsive ...
Influence of menstrual factors, reproductive history and exogeneous hormone use on women’s health: age at natural menopause, and cancer of the pancreas, non-Hodgkin lymphoma, and urothelial carcinoma
[spa] Antecedentes: La menopausia es un punto de inflexión en la salud de la mujer y está relacionada con un aumento del riesgo de osteoporosis y enfermedades cardiovasculares. Sin embargo, el riesgo de los cánceres ...
Involvement of Polyamines in Ribosome Biogenesis and Identification of Potential Genes Associated with Spermine Resistance in Arabidopsis thaliana
[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, ...
New strategies for improving the biotechnological production of taxanes
[eng] Plant specialized metabolism is the source of a wide range of bioactive compounds, some of which with relevant pharmacological properties. Nowadays, cancer is one of the main causes of mortality worldwide, therefore, ...
