Use of Urea and Ammonia to Produce High-Strength PM Aluminium Parts
(European Powder Metallurgy Association (EPMA), 2011)
Two methods to obtain bulk nanostructured aluminium parts are compared. The first one consists on milling Al powder in an ammonia gas atmosphere. In the second method, the Al powder is milled in vacuum with the addition ...

Simulating a P system based efficient solution to SAT by using GPUs
(Elsevier, 2010)
P systems are inherently parallel and non-deterministic theoretical computing devices defined inside the field of Membrane Computing. Many P system simulators have been presented in this area, but they are inefficient since ...

Spectral methods for bivariate Markov processes with diffusion and discrete components and a variant of the Wright-Fisher model
(Elsevier, 2012-09-01)
The aim of this paper is to study differential and spectral properties of the infinitesimal operator of two dimensional Markov processes with diffusion and discrete components. The infinitesimal operator is now a second-order ...

The ALHAMBRA survey: Evolution of galaxy clustering since z∼1
(Oxford University Press, 2014-06)
We study the clustering of galaxies as function of luminosity and redshift in the range 0.35< z < 1.25 using data from the Advanced Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey. The ALHAMBRA ...

Pterobreathers in a model for a layered crystal with realistic potentials: Exact moving breathers in a moving frame
(American Physical Society, 2019-08-12)
In this article we perform a thorough analysis of breathers in a one-dimensional model for a layered silicate for which there exists fossil and experimental evidence of moving excitations along the close-packed lines of ...

Barley Types and Varieties in Spain: A Historical Overview
(Universidad Católica de Chile, 2017)
Barley is currently the most cultivated crop in Spain, with an acreage of about three million ha. Its importance stems from its adaptation to areas with poor soil conditions and water stress. The aim of this work is to ...

Prefoldin-like Bud27 influences the transcription of ribosomal components and ribosome biogenesis in Saccharomyces cerevisiae
(Cold Spring Harbor Laboratory Press, 2020)
Understanding the functional connection that occurs for the three nuclear RNA polymerases to synthesize ribosome components during the ribosome biogenesis process has been the focal point of extensive research. To preserve ...

Effect of high SWNT content on the room temperature mechanical properties of fully dense 3YTZP/SWNT composites
(Elsevier, 2014)
This paper is devoted to correlate the microstructure and room temperature mechanical properties of single-wall carbon nanotube (SWNT) reinforced 3. mol% yttria stabilized tetragonal zirconia with high SWNT content (2.5, ...

N-acetylcysteine selectively antagonizes the activity of imipenem in Pseudomonas aeruginosa by an OprD-mediated mechanism
(American Society for Microbiology, 2015-01-01)
The modulating effect of N-acetylcysteine (NAC) on the activity of different antibiotics has been studied in Pseudomonas aeruginosa. Our results demonstrate that, in contrast to previous reports, only the activity of ...
