La delegificazione tra modello generale e prassi nella "giurisprudenza"consultiva del Comitato per la legislazione
2011
Funzione ausiliaria della Corte dei conti e disfunzioni strutturali della decisione finanziaria nello stato di democrazia pluralista
2021
Lo scritto affronta il tema delle difficili relazioni fra vincoli di bilancio euro-nazionale, autonomia finanziaria degli enti territoriali e garanzia dei livelli essenziali delle prestazioni concernenti i diritti civili e sociali. Si tratteggia dunque l'evoluzione del quadro normativo in tema di controlli sui bilanci degli enti territoriali e giudizi di parificazione per mostrare come ciò abbia condotto all’attivazione del sistema di garanzie giurisdizionali della Costituzione. Si presenta poi il tema dell’ausiliarietà della Corte dei conti mirando a collocarlo oltre i rapporti fra organi costituzionali e ad individuare i limiti dei controlli sugli atti di natura finanziaria. Si prende dun…
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 …
Régimen jurídico del Protocolo en España
2018
Propugnamos que el protocolo es el conjunto de principios, normas jurídicas, usos y costumbres, también jurídicas, principios generales del Derecho y criterios de los Tribunales de Justicia que determinan el orden de celebración de los actos oficiales y los elementos que intervienen en los mismos, que tienen como fin transmitir el reflejo externo de la caracterización y consideración, tanto social como jurídica del Poder en el Estado. Es, pues, ese reflejo externo, en su doble vertiente, uno de los fines del protocolo. No obstante entendemos el mismo como un conjunto de elementos: símbolos, tratamientos, regulación de la Casa Real, Derecho Premial y Nobiliario y, sobre todo, normas regulado…

Marine Discharges of Offshore Produced Water: the North-East Atlantic Management Strategy
2002
Este capítulo contiene un estudio de Derecho internacional del medio ambiente sobre las normas y estrategias para prevenir y eliminar la contaminación resultante de hidrocarburos y otras substancias causadas por las descargas de agua de producción costa afuera en el mar. Debemos tener en cuenta que no existe ni un solo tratado internacional de ámbito mundial relativo a la contaminación por descargas de hidrocarburos contenidas en las aguas de producción generadas en las instalaciones costa afuera. De hecho, sólo hay una región marina donde existen normas jurídicas y estrategias para hacer frente a este problema de contaminación. La región marina es el Atlántico nordeste y la norma en cuesti…

Zooming on the exergetic cost formation process of a Multiple-Effects-Evaporation (MEE) desalination plant
2009
In this paper an advanced energetic and thermoeconomic analysis of a Multiple Effect Evaporation (MEE) process is proposed. Starting from the thermochemical fundamentals of desalination processes, a minimum theoretical work of separation is introduced, to be used as reference condition to assess the efficiency of desalination units. The attention is then focused on a forward feed MEE configuration; by abandoning the usual perspective oriented to analyse the system at an “overall plant” level, a zooming strategy is proposed to understand in depth the margins for systems’ improvement. Focusing on a single effect, different subprocesses and their mutual interactions are correctly recognized to…
Exergy analysis and thermoeconomic cost accounting of a CHP steam cycle integrated with MED-TVC desalination
2016
In this paper exergy analysis and thermoeconomic cost accounting of a CHP steam cycle integrated with MED-TVC plant is performed; the purpose is to show how this methodology provides a rational criterion to allocate production costs on electricity and freshwater. After a brief overview on methodology and a description of reference plant, exergy analysis is carried out in order to calculate exergy flows and plant exergetic performance. A detailed description of the adopted thermoeconomic model is given. Cost accounting is performed considering two scenarios: in the first, the concentrated brine is disposed back to sea, thus being its exergy content definitively wasted; in the second, convers…
