Membrane bioreactors (MBR) are a combination of common bioreactors and membrane filtration units for biomass retention, presenting unique advantages like high effluent quality and a smaller footprint than the one by ...
The exponential increase of the atmospheric concentration of green-house gases due to human activities is responsible for the acceleration of global warming and climate change. Recently, scientific studies have pointed ...
Els ions metàl·lics són contaminants no biodegradables que es poden trobar a les aigües i que poden acumular-se en els organismes vius, causant diverses malalties i trastorns. Un dels metalls més contaminant i àmpliament ...
La presente tesis realizó el análisis y evaluación de los métodos estadísticos para valorar la calidad del café. En este sentido, se dio un aporte para tratar de cuantificar y cualificar la calidad del café mediante las ...
La tesi doctoral que es presenta a continuació té com a objectiu estudiar la percepció que tenen els consumidors espanyols del peix d’aqüicultura en comparació amb el peix salvatge, des de vàries perspectives: percepció ...
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 ...
The research for new technologies able to determine quality parameters as well as study the effect of High Pressure Processing (HPP) on dry-cured ham is of scientific interest because the information obtained is useful for ...
Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
Aquesta tesi doctoral i tot el treball experimental s’ha realitzat dintre les línies de treball del grup de recerca, Laboratori d’Enginyeria Paperera i Materials Polímers (LEPAMAP) de l’Escola Politècnica Superior de la ...
Brown spot of pear is a fungal disease caused by Stemphylium vesicarium. Currently, the disease control efficacy is limited, due to the characteristics of disease and the reduction of the allowed fungicides. Therefore, ...
The aim of the present work was to study the effects of tylosin A and doxycycline administration to laying hens on egg nutritional and compositional parameters during antibiotic treatment and after a withdrawal period. ...
The main objective of this thesis is to characterize and evaluate the capacity of cork and by-products of the cork industry (collectively called as cork samples) as biosorbents of aqueous polycyclic aromatic hydrocarbons ...
This thesis represents an important contribution to facilitate the efficient creation of detailed inventories to carry out Life Cycle Assessment (LCA) studies of urban wastewater systems. Specifically, this thesis provides ...
Fire blight is a disease caused by Erwinia amylovora. For the limited effectiveness of copper products and the new regulations for the sustainable use of pesticides, biological control is considered a good alternative for ...
The thesis deals with removal of organosilicon compounds in the energy recovery of biogas. Alternative adsorbents for the siloxane removal were studied, and the physical and chemical mechanisms involved in the siloxane ...
This thesis studies the effect produced by the reinforcement of polypropylene with a semichemical fibre of Leucaena collinsii in the mechanical, thermal and water uptake properties. Samples with different reinforcement ...
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 ...
With sustainable development as the new overarching goal, urban wastewater system (UWS) managers are now being asked to take all social, economic, technical and environmental facets related to their decisions into account. ...
Coming from renewable and sustainable raw materials, nanocelluloses are rapidly emerging as one of the most promising future materials. Recently, the use of nanocellulose nanocomposites in flexible electrodes, biosensors ...
The selection of the most appropriate wastewater treatment involves a complex decision making process. For that reason, some tools have been developed in recent years in order to deal with this complexity, as Novedar_EDSS ...
