Movement is a widespread characteristic in the animal kingdom —occurring at many spatiotemporal scales— with consequences at an individual, population, species, and even ecosystem level. It is a very diverse character, ...
This thesis has its main focus on developing multi-functional nanomaterials, that we called nano- and microtools through two different approaches, top-down to provide support and bottom up to give functionality to prepare ...
[eng] Our planet is impacted by diverse natural and human-induced events, including weather-related events (floods, droughts, forest fires, etc.) and geological events (landslides, earthquakes, volcanic eruptions, etc.). ...
In the last decades, anthropogenic inputs of nitrogen to groundwater have dramatically increased, and they nowadays represent one of the most important water resources concerns as NO3-N has become the most ubiquitous ...
Non-Communicable Diseases (NCDs), including cancer, cardiovascular (heart diseases or stroke), respiratory (COPD or asthma) and metabolic diseases (diabetes) are chronic conditions that represent a major global health ...

Todos los resultados expuestos en esta Tesis Doctoral sugieren que la ADA de la superficie celular así como sus proteínas de unión tienen un carácter multifuncional. Esto abre nuevas perspectivas en el estudio de la ...
This thesis, entitled "Multifunctional Self-stratified Polyurethane-Polyurea Nanosystems for Smart Drug Delivery" is structured as a compendium of publications, being organized around a methodological synthetic patent and ...
A first goal of this thesis is to contribute to the knowledge of cohomological properties of non-standard multigraded modules. In particular we study the Hilbert function of a non-standard multigraded module, the asymptotic ...
El problema central sobre el qual s’estructura aquesta tesi és la voluntat de suggerir una resposta no dicotòmica al conflicte unilingüisme/bilingüisme, tal com es viu i es llegeix des de la societat catalana, posant ...
