Natural toxins include a multitude of toxic secondary metabolites produced by animals, bacteria, fungi algae, and plants that are generally not intended as environmental contaminants of concern for water quality. However, ...
Our bodies are complex machines whose functioning depends on multiple electrical signals controlled mainly by the nervous system. Afterwards, it is not illogical to think that one day artificial electrical impulses would ...
[spa] La presencia de partículas sólidas y/o líquidas en la atmósfera (aerosol atmosférico) tiene diversas implicaciones sobre el clima, la visibilidad, la salud de los humanos y diversos ciclos biogeoquímicos. Debido a ...
La producción de sedimento en suspensión es la más importante que acarrean los ríos a los océanos y mares del mundo. El estudio en el que se basa la presente tesis se ha llevado a cabo en la cuenca del río Anoia, afluente ...
[spa] El objeto de nuestro estudio es la suspensión e interrupción del juicio ejecutivo. Pero es imposible desarrollar dicho tema sin que antes dediquemos parte de nuestro trabajo a considerar aquellas nociones generales ...
Los Moluscos Opistobranquios, en relación a la reducción o incluso pérdida de la concha, han desarrollado múltiples y sofisticados métodos de defensa (incluyendo la defensa química) que les han permitido sobrevivir sin ...
The main objective of this study was to develop a new forecasting method i.e. SutteARIMA method. SutteARIMA was developed by using a combination and/or weaknesses of some forecasting methods that already exist (α-Sutte ...
[eng] In this thesis, I investigate different synaptic and circuit mechanisms of working memory, how their interaction produces specific working memory biases, and how their disruption in psychiatric or neurological disease ...
The cerebral cortex is organized in complex circuits of neurons strongly interconnected in a conductive medium. During deep sleep stage, this neuronal connectivity generates recurrent synchronized synaptic activity leading ...
Synapses are the contact sites where the transfer of information from the presynaptic to the postsynaptic site occurs. Correct processing of information requires that synapses continuously adapt their properties to an ...
Modern oncology conceives solid tumours as organs by themselves, meaning that not only should the behaviour of cancer cells to be considered and evaluated therapeutically, but also the so-called tumour microenvironment. ...
The present doctoral thesis has been devoted to the use of 1,2,4,5-tetrazines as potential tools for chemical biology. Tetrazines have become extremely interesting functionalities due to their ability ...
Peptides are defined as compounds that contain between two and fifty amino acids connected together by amide bonds. Inside our body, peptides are natural biological messengers that play critical roles in human physiology ...
The thesis consists of two main projects: a) the development of a novel strategy to gain genetic control with spatiotemporal precision, and b) the optimisation of inhibitors of the protein kinase p38α, which has a major ...
Malaria is a parasitic disease caused by Plasmodium parasites and it is transmitted by female Anopheles mosquito. P. falciparum has a complex life cycle that includes important stages in two different hosts: a mosquito and ...
Nowadays, Nanotechnology is having an impact on practically every aspect of human life. It is a transformative technology that has influenced and will continue on electronics, computers, medicine, catalysis, energy, and ...
The concept of nanotechnology is attributed to Nobel prize winner Richard Feynman who gave a very famous, visionary in 1959 (published in 1960) during one of his lectures, saying: "the principles of physic, as far as I can ...
The goal of the present investigation is to examine the processing-structure-property relationships of multilayer graphene nanowall materials. Various plasma enhanced chemical vapor deposition (PECVD) processing parameters ...
[eng] Nanostructured semiconductors have gained significant importance due to their size- and morphology-tunable physical properties, and their ability to play a critical role in various fields such as energy conversion ...
The present Thesis is divided in three chapters: 1. Design and synthesis of new soluble epoxide hydrolase inhibitors (sEHI) The synthesis of new soluble epoxide hydrolase inhibitors based on ureas as the main ...
