Global pressures, specific responses: effects of nutrient enrichment in streams from different biomes
(IOP PUBLISHING LTD, 2013-01-09)
We assessed the effects of nutrient enrichment on three stream ecosystems running through distinct biomes (Mediterranean, Pampean and Andean). We increased the concentrations of N and P in the stream water 1.6–4-fold ...
A Temperature Sensor Based on a Polymer Optical Fiber Macro-Bend
(MDPI, 2013-10)
The design and development of a plastic optical fiber (POF) macrobend temperature sensor is presented. The sensor has a linear response versus temperature at a fixed bend radius, with a sensitivity of 1.92.10(-3) (degrees ...
Proof of Concept of Impact Detection in Composites Using Fiber Bragg Grating Arrays
(MDPI, 2013-09)
Impact detection in aeronautical structures allows predicting their future reliability and performance. An impact can produce microscopic fissures that could evolve into fractures or even the total collapse of the structure, ...
Performance of an Ocean Energy Conversion System with DFIG Sensorless Control
(Hindawi Publishing Corporation, 2013-05)
The 2009/28/EC Directive requires Member States of the European Union to adopt a National Action Plan for Renewable Energy. In this context, the Basque Energy Board, EVE, is committed to research activities such as the ...
Neuroprotective Effect of Melatonin: A Novel Therapy against Perinatal Hypoxia-Ischemia
(MDPI AG, 2013-04-29)
One of the most common causes of mortality and morbidity in children is perinatal hypoxia-ischemia (HI). In spite of the advances in neonatology, its incidence is not diminishing, generating a pediatric population that ...
Environmental judgment in early childhood and its relationship with the understanding of the concept of living beings
(Springer, 2013)
The evidence collected concerning the biocentric judgment that young children express when evaluating human actions on the environment leads some scholars to suggest that an essential understanding of the notion of living ...
Dynamics of Streptococcus pneumoniae Serotypes Causing Acute Otitis Media Isolated from Children with Spontaneous Middle-Ear Drainage over a 12-Year Period (1999–2010) in a Region of Northern Spain
(Public Library of Science, 2013-01-22)
The aim of this study was to determine the serotype and clonal distribution of pneumococci causing acute otitis media (AOM) and their relationship with recurrences and mixed infections with other microorganisms under the ...
The Influence of the Val158Met Catechol-O-Methyltransferase Polymorphism on the Personality Traits of Bipolar Patients
(Public Library of Science, 2013-04-30)
Introduction: Certain personality traits and genetic polymorphisms are contributing factors to bipolar disorder and its symptomatology, and in turn, this syndrome influences personality. The aim of the present study is to ...
Molecular Techniques for Dicistrovirus Detection without RNA Extraction or Purification
(Hindawi Publishing Corporation, 2013)
Dicistroviridae is a new family of small, nonenveloped, and +ssRNA viruses pathogenic to both beneficial arthropods and insect pests as well. Triatoma virus (TrV), a dicistrovirus, is a pathogen of Triatoma infestans ...
A Computational Module Assembled from Different Protease Family Motifs Identifies PI PLC from Bacillus cereus as a Putative Prolyl Peptidase with a Serine Protease Scaffold
(Public Library Science, 2013-08)
Proteolytic enzymes have evolved several mechanisms to cleave peptide bonds. These distinct types have been systematically categorized in the MEROPS database. While a BLAST search on these proteases identifies homologous ...
