Properties of flexible polyurethane foams containing isocyanate functionalized kraft lignin
(Elsevier, 2017-02-20)
A commercial kraft lignin (k-lignin) was successfully functionalized by means of the reaction of an isocyanate group from isophorone diisocyanate (IPDI) with hydroxyl groups present in lignin (k-IPDI), for their further ...
Association between birthweight and later body mass index: an individual-based pooled analysis of 27 twin cohorts participating in the CODATwins project
(Oxford University Press, 2017-10)
Background: There is evidence that birthweight is positively associated with body mass
index (BMI) in later life, but it remains unclear whether this is explained by genetic factors
or the intrauterine environment. We ...
Detecting the presence-absence of bluefin tuna by automated analysis of medium-range sonars on fishing vessels
(Public Library Science, 2017-02-02)
This study presents a methodology for the automated analysis of commercial medium range sonar signals for detecting presence/absence of bluefin tuna (Tunnus thynnus) in the Bay of Biscay. The approach uses image processing ...
Novel control algorithm for MPPT with Boost converters in photovoltaic systems
(Elsevier, 2017-07)
The great advances in efficiency and performance of photovoltaic modules would not be very useful if they do not work close to their maximum power point (MPP). In this paper a novel Sliding Mode Control (SMC) based algorithm ...
Contributions of Bottom-Up Energy Transitions in Germany: A Case Study Analysis
(MDPI, 2017-04)
Within the context of an energy transition towards achieving a renewable low-impact energy consumption system, this study analyses how bottom-up initiatives can contribute to state driven top-down efforts to achieve the ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Paleoenvironmental and Paleoclimatic approach to the Late Pleistocene site of Artazu (Arrasate, Northern Iberian Peninsula) using small vertebrates
(Asociación Paleontológica Argentina, 2017-04-20)
The Artazu VII site (Arrasate, northern Iberian Peninsula) is a fossiliferous deposit that was discovered unsystematically at the Kobate Quarry in 2012. During the following year, all the vertebrate remains attributed to ...
Parametric study of low-profile vortex generators
(Elsevier, 2017-07-13)
Vortex generators (VGs) are flow control devices employed to avoid or delay flow separation. In most cases, the VG is calculated with the same height as the boundary layer (BL) thickness at the device position. However, ...
Subtitling for d/Deaf and Hard-of-Hearing Children: Current Practices and New Possibilities to Enhance Language Development
(MDPI AG, 2017-06-30)
In order to understand and fully comprehend a subtitle, two parameters within the
linguistic code of audiovisual texts are key in the processing of the subtitle itself, namely, vocabulary
and syntax. Through a descriptive ...
Sugar–peptidic bond interactions: spectroscopic characterization of a model system
(2017-04-11)
Sugars are small carbohydrates which perform numerous roles in living
organisms such as storage of energy or as structural components. Modifications of specific sites
within the glycan chain can modulate a carbohydrate’s ...
