(2012-11-22)Este artículo presenta una secuencia didáctica basada en el enfoque del proceso de enseñanza-aprendizaje de la lengua mediante la investigación y la interacción. El objetivo es proponer una manera de ... -
Consumo y convergencia mediática de la prensa local en Cataluña
(2012-11)Los nuevos hábitos de consumo de medios en el marco de la convergencia digital están propiciando un cambio en las estrategias de los medios de comunicación. Mientras unos usuarios siguen prefiriendo la ... -
Market Stock Decisions Based on Morphological Filtering
(2010)In this paper we use a nonlinear processing technique based on mathematical morphology to develop a simple day trading system that automatically decides the timing to commute the marked strategy in ... -
Coarse frequency estimation in ofdm packet oriented systems
(2001)In this paper we derive a fast blind coarse frequency offset estimator for OFDM systems in selective frequency channels. The estimator takes advantage of the strong structure of the OFDM signal. In ... -
The abundance and suitability of tree cavities and their impact on hole-nesting bird populations in beech forests of NE Iberian Peninsula
(2008)Abstract. The availability and suitability of tree cavities for hole-nesting birds were surveyed in three beech wood types (mature, cleared and coppice forests) in the North east of the Iberian Peninsula. ... -
Technology of Islamic lustre
(2008)Replications of the lustre layers have been produced using laboratory-controlled conditions, based on a 13th century AD lustre recipe. The characteristics of the lustre layers obtained by using different ... -
Els Plans Individualitzats en les regulacions del Departament d’Educació de juny de 2008. Aplicació d’enfocaments multidimensionals en la seva elaboració
(2009)Recentment, el Departament d’Educació de la Generalitat de Catalunya ha publicat regulacions sobre els plans individuals per als alumnes considerats més vulnerables. Se n’han determinat els components ... -
Do protein–protein interaction databases identify moonlighting proteins?
(2011)One of the most striking results of the human (and mammalian) genomes is the low number of protein-coding genes. To-date, the main molecular mechanism to increase the number of different protein ... -
Malignant pheochromocytoma in a pig
(2011)Abstract. Endocrine tumors are rarely observed in pigs, and pheochromocytomas have been only punctually described. The current report describes a white and firm, 15-cm in diameter, neoplastic mass ... -
Skewed expression and up-regulation of the IL-12 and IL-18 receptors in resting and activated CD4 T cells from HIV-1-infected patients
(2007)IL-12 and IL-18 synergistically induce the production of IFN- by resting and activated T cells. To evaluate whether this induction was affected in HIV-1-infected patients, PBMC or isolated CD4 T ... -
Gene Ontology Function prediction in Mollicutes using Protein-Protein Association Networks
(2011)Abstract Background: Many complex systems can be represented and analysed as networks. The recent availability of large-scale datasets, has made it possible to elucidate some of the organisational ... -
Infinitely many periodic orbits for the rhomboidal five-body problem
(2006)We prove the existence of infinitely many symmetric periodic orbits for a regularized rhomboidal five-body problem with four small masses placed at the vertices of a rhombus centered in the fifth mass. ... -
Families of periodic orbits for the spatial isosceles 3-body problem
(2004)We study the families of periodic orbits of the spatial isosceles 3-body problem (for small enough values of the mass lying on the symmetry axis) coming via the analytic continuation method from ... -
Estudi de la població de Spiraea crenata subsp. parvifolia (Rosaceae) del Collsacabra
(2011)Spiraea crenata subsp. parvifolia és un tàxon endèmic del nord-est ibèric, que té una de les escasses poblacions conegudes al Collsacabra, Osona. En aquest treball es pretén definir l’extensió ... -
The number of planar central configurations for the 4-body problem is finite when 3 mass positions are fixed
(2005)In the n{body problem a central con guration is formed when the position vector of each particle with respect to the center of mass is a common scalar multiple of its acceleration vector. Lindstrom ... -
FAM-MDR: a flexible family-based multifactor dimensionality reduction technique to detect epistasis using related individuals
(2010-04)We propose a novel multifactor dimensionality reduction method for epistasis detection in small or extended pedigrees, FAM-MDR. It combines features of the Genome-wide Rapid Association using Mixed ... -
Self-organization mechanisms for the formation on nearshore crescentic and transverse sand bars
(2002)The formation and development of transverse and crescentic sand bars in the coastal marine environment has been investigated by means of a nonlinear numerical model based on the shallow-water equations ... -
A subcritical instability of wave-driven alongshore currents
(2004)The development of shear instabilities of a wave-driven alongshore current is investigated. In particular, we use weakly nonlinear theory to investigate the possibility that such instabilities, which ...
