Development of a general model to estimate the instantaneous, daily, and daytime net radiation with satellite data on clear-sky days
2015
Net radiation is a key variable in computing evapotranspiration and is a driving force in many other physical and biological processes. Remote sensing techniques provide an unparalleled spatial and temporal coverage of land-surface attributes, and thus several studies have attempted to estimate net radiation by combining remote sensing observations with surface and atmospheric data. However, remote sensing provides instantaneous data, when many applications and models need information at other temporal scales. In this work, a new general methodology is proposed to estimate daily and daytime net radiation and to retrieve the diurnal cycle of net radiation. Four images were acquired on differ…
Endocrine disrupter compounds removal in wastewater using microalgae: Degradation kinetics assessment
2018
[EN] This paper describes a study carried out to determine the removal kinetics of four micropollutants (4-tert-octylphenol (OP), technical-nonylphenol (t-NP), 4-nonylphenol (4-NP) and bisphenol-A (BPA)) usually found in wastewater streams. The kinetic experiments were carried out in batch reactors containing the effluent of an Anaerobic Membrane BioReactor (AnMBR) in the presence of light, oxygen and microalgae. As the degradation process of the studied micropollutants obeyed a pseudo-first-order kinetics, the second-order kinetics for each micropollutant was then calculated. The second order rate constants for the hydroxyl radical (k.(OH)) ranged from 7.0.10(+10) to 6.6.10(+12) L.mol(-1).…

An advanced control strategy for biological nutrient removal in continuous systems based on pH and ORP sensors
2012
[EN] A fuzzy logic-based control system that uses low-cost sensors for controlling and optimizing the biological nitrogen removal in continuous systems has been developed. The novelty of this control system is the use of several pH, ORP, and dissolved oxygen (DO) sensors instead of on-line nitrogen sensors/analyzers. The nitrogen control system was developed and implemented in a UCT pilot plant fed with wastewater from a full-scale plant. The developed nitrification controller allows the effluent ammonium concentration to be maintained below the effluent criteria discharge with the minimum energy consumption. The denitrification process controller allows the energy consumption derived from …
El delito por matar animales no estando su caza expresamente autorizada
2006
El artículo analiza los delitos tipificados en el Código Penal Español en relación con la caza de aquellos animales que por resolución o normativa administrativa tienen prohibida la caza. Y principalmente la integración del derecho penal por el derecho administrativo. The article analyzes the offenses established in the Spanish Penal Code in relation to the hunting of those animals that by resolution or administrative regulations are prohibited from hunting. And mainly the integration of criminal law by administrative law.

Land-Based Pollution in the Mediterranean Sea Area
1996
This paper deals with the political and legal regional approach adopted by the Mediterranean coastal States in order to prevent, abate, combat and eliminate to the fullest possible extent pollution of the Mediterranean Sea Area caused by discharges from rivers, coastal establishments or outfalls, or emanating from any other land-based sources and activities within their territories. I pay a special attention to the 1996 amendments to the Protocol for the Protection of the Mediterranean Sea against Pollution from Land-Based Sources (Athens, 17 May 1980).
Prevention of Offshore Pollution in the Mediterranean Sea Area
1998
Los Estados ribereños del Mediterráneo y la Comunidad Europea han adoptado diversos instrumentos políticos y jurídicos para la protección de la zona del Mar Mediterráneo contra la contaminación. De este modo, han creado un sistema ambiental regional que ha inspirado a otros acuerdos regionales a lo largo de todo el mundo bajo los auspicios del Programa de las Naciones Unidas para el Medio Ambiente. En este trabajo, estudio todas las medidas jurídicas y políticas adoptadas a nivel regional para prevenir, luchar, combatir y en la medida del máximo posible eliminar la contaminación de la zona del Mar Mediterráneo resultante de la explotación y explotación de la plataforma continental y del lec…
Environmental Law for the Black Sea Region
1999
This paper comments the characteristics of the environmental legal protection of the Black Sea (BS) region. In its first part, we shall examine the different characteristics of regional legal approaches all over the world dealing with environmental protection of semi-enclosed or closed seas. Subsequently, we will focus our attention on the environmental protection of the BS region, analysing first the main features of the BS regional co-operation in marine environmental affairs and second the environmental legal protection of the BS region
