Las declaraciones de impacto ambiental en estaciones depuradoras de aguas residuales
(TIASA, 2008)
Se hace patente el principio de prevención como guía de la política medioambiental, estableciendo en las DIAs la adopción de todas aquellas medidas que eviten impactos. La minimización, que se muestra en la necesidad de ...
Experimental evaluation of the energy efficiency of a CO2 refrigerating plant working in transcritical conditions
(2008)
This work presents the experimental evaluation of the energy efficiency and optimal gas-cooler pressures of a single-stage refrigerating plant working with carbon dioxide as refrigerant in transcritical conditions. The ...
Biometanización a partir de lodos de EDAR y rechazos de planta de compostaje
(TIASA, 2009)
La mezcla de rechazos procedentes de plantas de compostaje y de lodos de EDAR urbanas se plantea como una alternativa para la valorización de estos residuos mediante su biometanización. Con ello se puede obtener un último ...
Activity modelling in a collaborative ceramic tile design chain: an enhanced IDEF0 approach
(Springer-Verlag, 2008)
Explicit descriptions of should-be and to-be activities and processes are key elements in implementing industrial projects aimed at improving new-product development (NPD) processes, especially when e-collaboration utilities ...

Computer-aided sketching as a tool to promote innovation in the new product development process
(Elsevier, 2009)
Sketching is an established part of engineering culture. Sketches assist product designers during the creative stages of design and help them to develop inventions. Paper-and-pencil sketching is highly useful but lacks ...
Averaging methods of the gap heat transfer coefficients and the loss form coefficients of nuclear reactor cores loaded with different fuel bundles
(Elsevier, 2009)
When performing transient analysis in heterogeneous nuclear reactors loaded with different types of fuel bundles is necessary to model the reactor core by a few representative fuel elements with average properties of a ...
Automated modelling of complex refrigeration cycles through topological structure analysis
(Elsevier, 2009)
We have developed a computational method for analysis of refrigeration cycles. The method is well suited for automated analysis of complex refrigeration systems. The refrigerator is specified through a description of flows ...
Comparison of environmental impacts of building structures with in situ cast floors and with precast concrete floors
(Elsevier, 2009)
In this paper, the environmental impacts of two types of slab systems are studied. The first type, a concrete-based one-way spanning slab, is the most common solution in residential buildings in Spain. The second type, a ...
