Summary Nowadays, ammonium (NH4+) is a pollutant present in all kinds of water bodies, leading to multiple environmental and health issues. The current NH4+-removing technologies are very expensive, as they require a lot ...
In 2015 the average concentration of CO2 in the atmosphere exceeded 400 ppm. Some technologies, including CO2 capture and storage, are palliative. However, the development of alternatives to burning of fossil fuels focuses ...
Aquest és el primer informe que demostra que l'autofàgia està mecànicament vinculat al manteniment de les cèl•lules tumorals que expressen alts nivells de CD44 i baixos nivells de CD24, que són típics de les cèl•lules mare ...
Currently, global change is promoting the spatiotemporal occurrence of temporary streams, altering fluvial ecosystem function and structure, and the ecosystem services they provide. To effectively protect fluvial ecosystems, ...
The main goal of this thesis is to investigate the effects of consequences of global change on fluvial biofilms. To achieve this objective a multi-marker approach has been used at different experimental scales. Our results ...
The oxidation of hydrocarbons is one of the most important processes in the chemical industry, and it is often related to highly toxic reagents that generate a big amount of undesired residues. In sharp contrast, oxygenase ...
La gran eficiència, selectivitat i les condicions suaus exhibides per les reaccions que tenen lloc al centre actiu de les metal·looxigenases són la font d'inspiració per la present dissertació. Amb l'objectiu de dissenyar ...
The oxidation of hydrocarbons under soft and selective conditions is a reaction almost exclusively produced under these conditions by enzymes. A lot of these enzymes, posses iron in their metal center, responsible for the ...
Nowadays, one of the main goals in organic chemistry and fine industry is the development of new synthetic methodologies for the preparation of life-relevant products in a sustainable manner. The use of first-row ...
Selective oxidation of C-H bonds is an important reaction, as it can disclose novel synthetic strategies to get functionalized products through efficient paths. Nonetheless, due to the inert character of C-H bonds, the use ...
The functionalization of hydrocarbons in a sustainable manner is one of the main challenges for chemists. Their abundance in nature as natural gas or crude oil makes them the most convenient chemical feedstock. The oxidation ...
The fruit production is threatened by several bacterial diseases, such as fire blight of apple and pear, bacterial canker of kiwifruit, bacterial spot of stone fruits, and angular leaf spot of strawberry. The conventional ...
Biological nutrient removal has been studied and applied for decades in order to remove nitrogen and phosphorus from wastewater. However, more anthropogenic uses and the continued demand for water have forced the facilities ...
La resposta inflamatòria d’un hoste pot ser excessiva o desregulada en relació a la intensitat o la durada d’una agressió. Quan aquesta resposta és secundària a una infecció es coneix com a sèpsia i pot acabar lesionant ...
Magnetic resonance imaging (MRI) is essential in the management of patients with glioblastoma, providing useful information for diagnosis, prognosis, and therapeutic planning. Although some presurgical and postsurgical ...
The presence of nitrates (NO3-) in groundwater is a worldwide concern. The high energy demand and environmental impact of available technologies requires investigating new technologies. This thesis was focused on investigating ...
Given that the poetry of Blai Bonet has been thoroughly examined, this study is focused on Blai Bonet as a novelist beginning with the analysis of his first novel, El mar (1958). The study is divided into three parts: “Blai ...
The main objective of work has been to study the bond strength and bond-slip response of NSM CFRP strips in concrete when subjected to sustained loading under different environmental conditions. To this end, two experimental ...
The rehabilitation of civil structures has been gaining importance during the last decades. Owing to their mechanical, corrosion resistance and lightweight properties, Carbon Fibre-Reinforced Polymers (CFRP) present an ...
In this work, a methodology has been developed to implement the bond behaviour between concrete and GFRP bars in the numerical modelling. Based on experimental results and applying the inverse method, the bond law to be ...
