Evaluación de los efectos no intencionados de los transgenes en plantas modificadas genéticamente (MG) resistentes a plagas y diseñadas como biofactorías de péptidos antimicrobianos
Genetically modified crops are submitted to strict regulation to ensure the safety of consumers and the environment. To complement the comparison between GM plants and their counterparts, in the present Thesis, we evaluated ...
Avaluació del paradigma d'agents en la gestió d'un sistema complex d'aigües residuals
The thesis presents and evaluates the application of the paradigm of agents to the management of the urban wastewater system. The system is conceptualised as a multi-agent system from the development of the models of ...
Desenvolupament d'un protocol per l'aplicació de sistemes basats en el coneixement a la gestió d'estacions depuradores d'aigües residuals urbanes
In this thesis, it is presented a research for the implementation of a supervisory system that integrates different technical to complement and improve the management of Waste Water Treatment Plants. The protocol proposed ...
Estudi del comportament de sistemes biològics de depuració d'aigües residuals mitjançant models mecanístics, optimitzant la informació disponible de les dades obtingudes en línia
The use of simulation as an upgrading tool has been tested on real wastewater treatment plants (WWTP). Currently, the new WWTP have the possibility to monitor some process variables as the flows, oxygen concentrations and, ...
Interacció Pseudomonas syringae pv. syringae-perera. Factors determinants i activitat de diversos fosfonats en el desenvolupament de la malaltia
Blast of pear caused by Pseudomonas syringae pv. syringae is one of the bacterial disease that limit pear production throughout the world. Symptoms are characterized by blast of buds and blossoms wich causes significant ...
Effects of breed and PRKAG3 and CAST genetic polymorphisms on the quality of serrano dry-cured ham
Two pieces of complementary research dealing with the study of the importance of genetic factors on the quality of the Spanish dry-cured ham Jamón Serrano were carried out for this thesis. The first one compared Serrano ...
Preparación y evaluación de formulaciones acrílicas autocurables de baja toxicidad modificadas con polímeros biodegradables para cirugía ortopédica y mínimamente invasiva
In the present work, a study of the preparation of new formulations of acrylic bone cements (ABC) has been carried, to obtain materials with capacity for controlled drug delivery of medicaments useful in the therapeutic ...
Applications of computed tomography in dry-cured meat products
Computed Tomography and Microcomputed Tomography are X-ray based technologies. They were tested in this thesis as potential tools for the optimization of the processing of dry-cured meat products. On one hand, several ...
Integrated management of urban wastewater systems: a model-based approach
The main objective pursued in this thesis targets the development and systematization of a methodology that allows addressing management problems in the dynamic operation of Urban Wastewater Systems. The proposed methodology ...
Development of a decision support system for the integrated control of membrane bioreactors
The work presented in this PhD thesis includes various partial studies aimed at developing a decision support system for membrane bioreactor integrated control. The decision support systems (DSS) have as a main goal to ...
Treatment of mature urban landfill leachates by anammox process
This thesis results from the collaborative projects between the LEQUIA-UdG group and Cespa (a company in charge of several landfill sites in Spain). The aim of the work was the development of a suitable alternative treatment ...
Procesos secuenciales de adsorción/oxidación con H2O2 para la eliminación de compuestos orgánicos volátiles
Volatile Organic Compounds (VOCs) are one of the main groups of odour causing compounds in Waste Water Treatment Plants (WWTP). Adsorption technology is already established, in recent years the interest for the optimization ...
Estratègies prèvies al sacrifici que poden afectar el benestar animal i la qualitat de la carn de porcs de diferent genotip RYRI
The main objective of this thesis was to study (i) the effect of the fasting and lairage on carcass and technological meat quality and (ii) the inclusion of magnesium (MgCO3 and MgSO4) and/or tryptophan during 5 days before ...
Knowledge-based modelling and simulation of operational problems of microbiological origin in wastewater treatment plants
The activated sludge and anaerobic digestion processes have been modelled in widely accepted models. Nevertheless, these models still have limitations when describing operational problems of microbiological origin. The aim ...
Development of an air-scour control system for membrane bioreactors
The thesis involves the development and implementation of a new and robust control system based on permeability trends but at the same time capable of reducing aeration proportionally to permeate flux. Permeability was ...
Modificacions en la dinàmica de processat i en les característiques finals de productes carnis amb contingut reduït de sodi
In recent years, several studies have linked sodium intake to hypertension, and the consequent mortality risk due to vascular diseases. Several UE member states and the WHO recommend reducing the salt intake level to a ...
Biological nutrient removal in SBR technology: from floccular to granular sludge
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 ...
Emissions de N2O i desnitrificació en sòls agrícoles i d'ecosistemes naturals. Factors de regulació
La major conscienciació actual dels problemes de pol·lució que acompanyen les pèrdues de N del sòl cap a l'atmosfera ha reorientat les investigacions cap a un coneixement més profund dels processos implicats en les emissions ...
Partial nitritation of landfill leachate in a SBR prior to an anammox reactor : operation and modelling
Els lixiviats d'abocadors urbans són aigües residuals altament contaminades, que es caracteritzen per les elevades concentracions d'amoni i el baix contingut de matèria orgànica biodegradable. El tractament dels lixiviats ...
Allocation of GHG emissions in a paper mill, an application tool to reduce emissions
El sector de pasta i paper és considerat un dels set sectors industrials més intensius en consum energètic. La producció i consum d'electricitat i de vapor esdevenen les fonts majoritàries d'emissions de gasos d'efecte ...
