The present doctoral dissertation deals with the study of the effect of food preservation technologies, such as high pressure (HP) treatments and biopreservation with nisin, on the behaviour of Listeria monocytogenes during ...
The human visual ability to perceive depth looks like a puzzle. We perceive three-dimensional spatial information quickly and efficiently by using the binocular stereopsis of our eyes and, what is mote important the learning ...
The main objective of the present dissertation is to empirically study the integration of management systems (MSs). Specifically, we aim to investigate how organizations carry out the integration process, which benefits ...
El objetivo del estudio era explorar y comprender los modelos de mujer con los que sintonizan dos grupos: "Estándar" (población general; estudiado mediante cuestionarios administrados a jóvenes en institutos y universidad), ...
Adhesives have been shown to be an excellent solution for joining fibre reinforced polymer (FRP) components thanks to their capacity to redistribute loads, reduces stress concentrations and contribute to overall weight ...
Antibiotic residues in the environment are amongst the most concerning micropollutants due to their potential impact on the natural ecosystems and human health. In this thesis, laboratory and field studies were conducted ...
Spatial statistics is traditionally based on stationary models like Matérn fields. However, applying stationary models to complex spatial regions having physical barriers like islands or coastal areas can result in ...
The use of the stiffened panels in the aircraft/aeronautical industry has been growing in the last decades. On the other hand, the exponential growth in the use of composite materials in the last years has had a ...
La present tesi proposa una metodología per a la simulació probabilística de la fallada de la matriu en materials compòsits reforçats amb fibres de carboni, basant-se en l'anàlisi de la distribució aleatòria de les fibres. ...
Interactions between electrons determine the structure and properties of matter from molecules to solids. Therefore, the understanding of the electronic structure of molecules will enable us to extract relevant chemical ...
In order to evaluate the increasing environmental and human risk of anticancer drugs in the environment, more information needs to be gathered about their presence, their toxicity, bioaccumulation and persistence. In ...
This thesis presents different studies on hydrogen bonds that occur between two molecules. It is because of the biological importance of DNA that the base pairs, and other compounds with similar hydrogen bonds as these ...
Adhesive bonds could replace more traditional mechanical joints, making structures lighter and smoother. Stresses are distributed over a larger area, and dissimilar materials can be bonded, accommodating differences in ...
Currently, the use of Automated Fiber Placement technology allows, large composite aircraft components to be manufactured with high quality materials and introduce new laminate concepts. Among such concepts are the tow-steered ...
This thesis is a compilation of 3 articles, and the main focus of attention is the learning transfer mechanism. The first article explains the Rugby Attack Assessment instrument, a tool that assesses game performance of ...
In this work, long-term behaviour of FRP RC beams has been investigated both analytically and experimentally to further extend the knowledge in this particular research domain. In this respect, a new methodology to determine ...
The presence of xenobiotics - such as pharmaceutically active compounds, endocrine disrupting compounds and pesticides - in the aquatic environment has risen great environmental concern due to their high toxicity even at ...
La investigació que es presenta en aquesta tesi es centra en l'aplicació i millora de metodologies analítiques existents i el desenvolupament de nous procediments que poden ser utilitzats per a l'estudi dels efectes ...
Solid-phase microextraction (SPME) allow the achievement of high enrichment levels by using small volumes of solvents, enabling the low detection limits required for the determination of ketoprofen, naproxen, carbamazepine, ...
In this thesis, simple methods to determine sulfide at low levels (µg L-1) in aqueous samples and sediments by water free hydrogen sulfide vapor generation using a commercially available vapor generation accessory have ...
