Mass spectrometry coupled to imaging techniques: The better the view the greater the challenge
(Frontiers Research Foundation, 2015-01-21)
These are definitively exciting times for membrane lipid researchers. Once considered just as the cell membrane building blocks, the important role these lipids play is steadily being acknowledged. The improvement occurred ...
Fiber Bragg Gratings, IT Techniques and Strain Gauge Validation for Strain Calculation on Aged Metal Specimens
(MDPI, 2011-01)
This paper studies the feasibility of calculating strains in aged F114 steel specimens with Fiber Bragg Grating (FBG) sensors and infrared thermography (IT) techniques. Two specimens have been conditioned under extreme ...
Design and Development of a Low-Cost Optical Current Sensor
(MDPI, 2013-10)
In this paper we demonstrate the design of a low-cost optical current sensor. The sensor principle is the Faraday rotation of a light beam through a magneto-optical material, SF2, when a magnetic field is present. The ...
Regulation of Energy Metabolism by the Extracytoplasmic Function (ECF) σ Factors of Arcobacter butzleri
(Public Library of Science, 2012-09-18)
The extracytoplasmic function (ECF) σ factors are fundamental for bacterial adaptation to distinct environments and for survival under different stress conditions. The emerging pathogen Arcobacter butzleri possesses seven ...
Language distance and non-native syntactic processing: Evidence from event-related potentials
(Cambridge University Press, 2011)
[EN] In this study, we explore native and non-native syntactic processing, paying special attention to the language distance factor.
To this end, we compared how native speakers of Basque and highly proficient non-native ...
Socioeconomic impacts of National Parks: a case study from the North-east of England
(INGEBA, 2010)
[EN] Enforcement of rural policy measures within National Parks may have a particular importance as they may contribute to reach socioeconomic objectives devised for such areas. So this paper approaches as case study the ...
Influence of Humidity on Fiber Bragg Grating Sensors
(Hindawi, 2014-01)
We demonstrate the influence of the relative humidity (RH) on the wavelength of fiber Bragg grating sensors (FBGS), performing tests with five FBGS at different humidity and temperature conditions. These tests were performed ...
On-demand generation and removal of alginate biocompatible microvalves for flow control in microfluidics
(Elsevier, 2016-10-29)
[EN] This paper describes, for the first time, the use of alginate hydrogels as miniaturised microvalves within microfluidic devices. These biocompatible and biodegradable microvalves are generated in situ and on demand, ...
GmcA Is a Putative Glucose-Methanol-Choline Oxidoreductase Required for the Induction of Asexual Development in Aspergillus nidulans
(Public Library of Science, 2012-07-05)
Aspergillus nidulans asexual differentiation is induced by Upstream Developmental Activators (UDAs) that include the bZIP-type Transcription Factor (TF) FlbB. A 2D-PAGE/MS-MS-coupled screen for proteins differentially ...
Income tax progressivity, growth, income inequality and welfare
(Springer, 2015-03)
This paper analyzes the effects of personal income tax progressivity on long-run economic growth, income inequality and social welfare. The quantitative implications of income tax progressivity increments are illustrated ...
