The Sailor diagram – A new diagram for the verification of two-dimensional vector data from multiple models
(Copernicus Gesellschaft, 2020-07-15)
A new diagram is proposed for the verification of vector quantities generated by multiple models against a set of observations. It has been designed with the objective, as in the Taylor diagram, of providing a visual ...
Problem-Based Learning in University Studies on Renewable Energies: Case of a Laboratory Windpump
(MDPI, 2020-03-23)
In the last eight years, the new faculty of Engineering in Renewable Energies at the University of the Basque Country in Eibar has developed several sustainability goals related to clean energy and climate change, but also ...
The Binding of Aβ42 Peptide Monomers to Sphingomyelin/Cholesterol/Ganglioside Bilayers Assayed by Density Gradient Ultracentrifugation
(MDPI, 2020-02-29)
The binding of Aβ42 peptide monomers to sphingomyelin/cholesterol (1:1 mol ratio) bilayers containing 5 mol% gangliosides (either GM1, or GT1b, or a mixture of brain gangliosides) has been assayed by density gradient ...
Exploring Polar Headgroup Interactions Between Sphingomyelin and Ceramide with Infrared Spectroscopy
(Nature, 2020-10-19)
Ceramide is a major actor in the sphingolipid signaling pathway elicited by various kinds of cell stress. Under those conditions ceramide (Cer) is produced in the plasma membrane as a product of sphingomyelin (SM) hydrolysis, ...
Human behavioural adaptations to interglacial lakeshore environments. An introduction
(Propylaeum, University of Heidelberg, 2020-04-24)
During the course of human evolution, we have suc-
cessfully adapted to various environments. Chang-
ing climates and landscapes often required new
behavioural strategies for survival; human societies
indeed came into ...
A zooarchaeological and taphonomic perspective of hominin behaviour from Schöningen 13II-4 "Spear Horizon",
(Propylaeum, University of Heidelberg, 2020-04-24)
The Schöningen 13II-4 “Spear Horizon” is among the most famous lakeshore archaeological sites dating from the Middle Pleistocene in Europe. Multiple well-crafted wooden spears recovered together with a large assemblage of ...
Isothermal oxidation kinetics of nitrided Ti-6Al-4V studied by infrared emissivity
(Elsevier, 2020-08-15)
The oxidation kinetics of Ti-6Al-4V samples nitrided in forming gas (N2+5%H2) between 520 and 805 °C is investigated using infrared emissivity measurements. Several kinetic exponents have been observed depending on temperature ...
Human Behavioural adaptations to lakeshore environments
(Propylaeum, 2020-03-24)
During the course of human evolution, we have successfully adapted to various climates and habitats. Interglacial environments, in particular, offer an excellent opportunity to study these adaptations. On the north European ...
Derivational networks in Basque
(De Gruyter Mouton, 2020)
Video Image Enhancement and Machine Learning Pipeline for Underwater Animal Detection and Classification at Cabled Observatories
(MDPI, 2020-01-28)
An understanding of marine ecosystems and their biodiversity is relevant to sustainable use of the goods and services they offer. Since marine areas host complex ecosystems, it is important to develop spatially widespread ...
