Shell midden people in northern Iberia. New data from the mesolithic rock shelter of J3 (Basque Country, Spain)
(Ediciones Universidad de Salamanca, 2010)
[EN]In the course of a sondage dug in the rock shelter of J3, in the Jaizkibel mountains (at the north-western tip of Guipúzcoa), the body of a adult man was located buried inside a shell midden. This shell midden had not ...
HLA-DRB1*15:01 and multiple sclerosis: a female association?
(Sage, 2011-11-29)
Background: The association between multiple sclerosis (MS) and the HLA-DRB1*15: 01 haplotype has been proven to be strong, but its molecular basis remains unclear. Vitamin D receptor (VDR) gene variants and sex have been ...
Osteometric analysis of the scapula and humerus of Rangifer tarandus and Cervus elaphus : A contribution to the discrimination of Late Pleistocene cervids
(Inst Paleobiologii Pan, 2014-12)
Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The ...
A new Late Pleistocene non-anthropogenic vertebrate assemblage from the northern Iberian Peninsula: Artazu VII (Arrasate, Basque Country)
(Elsevier, 2016-06-29)
Late Pleistocene palaeontological sites without human intervention are limited in theCantabrian region, and even more so those with a good state of preservation and rich bio-diversity. A new vertebrate fossiliferous locality ...
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 ...
Gas analyzer's drift leads to systematic error in maximal oxygen uptake and maximal respiratory exchange ratio determination
(Frontiers Media, 2015-10)
The aim was to examine the drift in the measurements of fractional concentration of oxygen (FO2) and carbon dioxide (FCO2) of a Nafion-using metabolic cart during incremental maximal exercise in 18 young and 12 elderly ...
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. ...
