Characterization of protein conformational ensembles from Förster resonance energy transfer simulations
[eng] This thesis focuses on the study of partially disordered proteins (IDPs), using calmodulin (CaM) as the system under study. Calmodulin is a crucial protein involved in numerous physiological processes, and its ...
Metal catalysed asymmetric C–C bond forming reactions
[eng] This thesis presents novel methodologies for asymmetric C–C bond forming reactions, focusing on catalytic approaches involving chiral nickel(II) complexes. Chapter I introduces a new approach to direct asymmetric ...
Síntesis total de la Anfidinolida B1
[spa] En esta Tesis Doctoral se ha estudiado la síntesis total de la Anfidinolida B1, un macrociclo de 26 miembros aislado por primera vez por Shimizu y colaboradores en 1994 en Santo Tomás, una de las Islas Vírgenes de ...
Heterobifunctional molecules: PROTACs and beyond
[eng] Our body is an intricate, well-organized structure formed by trillions of cells. Each one of these cells is a highly complex entity composed of thousands of biomolecules that enable it to carry out its functions. ...
Comprehensive characterization of anthropogenic impacts on Mediterranean intermittent streams using cheminformatics and environmental risk assessment approaches
[eng] Intermittent streams, characterized by variable and discontinuous flow regimes, are becoming increasingly common in the Mediterranean region due to climate change, population growth and land use changes, which further ...
Biomonitoreo de contaminantes de preocupación emergente en especies invasoras y nativas para la evaluación del riesgo ecológico en ecosistemas acuáticos
[spa] La contaminación de ecosistemas acuáticos derivada de actividades antropogénicas puede generar graves consecuencias ambientales, como la degradación de la calidad del agua, la pérdida de biodiversidad, la acumulación ...
Understanding the sorption of radium and lanthanides in soils and biochars for predictive modelling and remediation purposes
[eng] The exponential increase in the demand for certain metals across various technological sectors has intensified mining and industrial activities. A consequence of these processes is the unintentional enrichment of ...
Design and regulation of high-performance catalysts in cathodes and separators for alkali metal-sulfur batteries
[eng] Alkali metal-sulfur batteries (MSBs) are considered to be the most promising materials to replace lithium-ion batteries (LIBs) in next-generation energy storage systems. Compared to LIBs, lithium sulfur batteries ...
Search and study of massive runaway stars in the Milky Way and impact on high-energy binaries
[eng] Massive stars are ubiquitous in many astrophysical phenomena. A significant fraction of massive stars are runaways, displaying high velocities with respect to their environment. Due to their formation scenarios, ...
Computational methods applied to chemical engineering
[eng] Computational tools, and more specifically Computational Fluid Dynamics (CFD) have seen a rapid development and increase in use in recent years thanks to the exponential growth that computing power experiences every ...
Recobriments d'or: avançant cap a una tecnologia més sostenible
[cat] En la indústria dels recobriments decoratius destaca l'ús d'aliatges d'or. Aquests recobriments es fabriquen majoritàriament mitjançant l’electrodeposició, una tècnica que requereix temps de treball reduïts i que ...
Development and assessment of magnesium phosphate cements by using industrial by-products and wastes
[eng] The construction sector is globally recognized as a significant contributor to environmental pollution, particularly in terms of climate change and the depletion of natural resources. These environmental impacts arise ...
Investigating the roles of MnO2-acid complexes in catalytic ozonation for enhanced micropollutants abatement in water
[cat] Amb el ràpid creixement de la població, es generen grans quantitats de contaminants orgànics que s'alliberen al medi aquàtic. Per eliminar aquests compostos refractaris, els processos d'oxidació avan9ada (A0Ps), entre ...
Engineering and microbiology insights into co-fermentation of waste activated sludge and food waste
[eng] According to the circular economy principles, wastewater treatment plants (WWTPs) should be transformed into water resource recovery facilities. Urban organic waste, including sewage sludge from WWTPs, can be converted ...
Phase Separation of the Intrinsically Disordered Activation Domain of the Androgen Receptor and Therapeutic Approaches
[eng] Transcription factors represent highly attractive therapeutic targets, yet they are among the most challenging due to the intrinsically disordered nature of their activation domains (ADs). In this study, we focus on ...
«Infancias activistas» y sus capacidades colectivas políticoepistémicas en la esfera adultocrática: una propuesta desde el enfoque de las capacidades
[spa] Esta disertación plantea una revisión crítica orientada a resignificar las infancias bajo el concepto de «infancias activistas», con el objetivo de cuestionar y transformar las estructuras adultocéntricas que, ...
Fortalecimiento de la escuela pública en escenarios de mercado: Significados atribuidos por docentes directivos a la Ley de Nueva Educación Pública en Chile.
[spa] El año 2017, el Gobierno de Chile aprueba la Ley 21.040 de Nueva Educación Pública (NEP). Esta legislación plantea que los establecimientos educativos públicos de dependencia municipal pasan a depender directamente ...
Chamber of Reflections: Text Mining for a Retrospective Analysis of Archaeological Heritage Discourse under the "Academic Gaze"
[eng] This thesis highlights the need for self-reflective analyses within the fields of Heritage, Education and Archaeology to evaluate the production of textual sources. By determining both the process through which the ...
L'aprenentatge informal dels joves amb persones desconegudes a internet. Aproximació a un fenomen glocal a partir d'un estudi de cas
[cat] La societat xarxa fa possible comunicar-nos amb persones d'arreu del món i aprendre conjuntament sobre interessos comuns. Els joves nascuts al segle XXI hi tenen accés a la tecnologia digital que ho facilita, però ...
Análisis de la Promoción del Aprendizaje Autorregulado en la Enseñanza y Aprendizaje de las Matemáticas por Futuros Profesores de Secundaria
