Incumplimiento y reemplazo : bases para una teoría general de la operación de reemplazo en derecho español
2013
La presente tesis versa sobre la operación de reemplazo en derecho español y tiene como propósito sentar las bases para una teoría general en torno ella. La elección de este tema se justifica por la falta de un tratamiento de conjunto dentro de la literatura científica española, que lo ha abordado con criterios más o menos uniformes desde que la renovación del derecho mercantil llamó la atención sobre él al promediar el siglo XX. La jurisprudencia también ha tenido ocasión de hacer aplicación de la figura, pero sin que las decisiones vertidas gocen de la uniformidad que sería deseable. El método utilizado es reconstructivo, vale decir, pretende unir, allegar, evocar las circunstancias e ide…
Role of acetaldehyde in alcohol addiction: current evidence and future perspectives
2011
The effects of alcohol have been widely studied during the past century, corroborating the idea that this tiny chemical compound acts throughout most of our neurotransmitter systems since it is capable of inducing addictive behaviour. Two of the most serious problems of alcohol addiction are craving and relapse; several studies have demonstrated that relapse is related to the anxious state which occurs during withdrawal, and it has been proved that this behavioural modifications results from an alteration of the dopaminergic and serotonergic systems. An important role in the neurobiology of alcohol addiction is played by acetaldehyde (ACD), ethanol first metabolite. Our recent studies indee…
Modulation of alcohol consumption using an operant self-administration paradigm: effects of a new dopamine aminoacidic conjugate, Phenylalanine-β(3,4…
2014
Rewarding and reinforcing properties of alcohol have been shown to be mediated by activation of the mesolimbic dopaminergic system. Experimental evidences suggest that mesolimbic dopamine system is hypofunctional in addicted brain; further, reduced dopaminergic activity outlasts somatic signs of withdrawal and may drive craving and relapse. Boosting strategy on dopaminergic neurons could represent a valid therapy. Effects of pharmacological manipulation of brain Dopaminergic receptors by a new dopamine conjugate, Phenylalanine-β(3,4dihydroxyphenyl)-etilamide (DA-Phen), on operant behaviour and on both acute and prolonged withdrawal symptoms during ethanol abstinence have been evaluated. Mal…

Hypervisor-Based White Listing of Executables

We describe an efficient system for ensuring code integrity of an operating system (OS), both its own code and application code. The proposed system can protect from an attacker who has full control over the OS kernel. An evaluation of the system's performance suggests the induced overhead is negligible. peerReviewed
A probabilistic long‐term framework for site‐specific erosion analysis of wind turbine blades: A case study of 31 Dutch sites
2021
Abstract Rain‐induced leading‐edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects of LEE can be triggered in less than 1 to 2 years for some wind turbine sites, whereas it may take several years for others. In addition, the growth of erosion may also differ for different blades and turbines operating at the same site. Hence, LEE is a site‐ and turbine‐specific problem. In this paper, we propose a probabilistic long‐term framework for assessing site‐specific lifetime of a WTB coating system. Case studies are presented for 1.5 and 10 MW wind turbines, where geographic bubble charts for the leading‐edge lifetime and number of repai…
Cyclists' Perception of Maintenance and Operation of Cycling Infrastructure—Results From a Norwegian Survey
2021
Aasvik O and Bjørnskau T (2021) Cyclists’ Perception of Maintenance and Operation of Cycling Infrastructure—Results From a Norwegian Survey. Front. Psychol. 12:696317. doi: 10.3389/fpsyg.2021.696317 The Norwegian authorities want to limit the extent of car use in city areas to existing levels. Such a limitation would help combat climate change, improve health of citizens, and alleviate congestion. This implies that any further increase in transport needs will have to be met by walking, cycling and use of public transport. Reaching this ambitious goal requires knowledge about cyclists' preferences concerning operation and maintenance (M&O) of roads and foot/cycle paths. Previous research sug…
