An insight into the reactions occurring during the chemical activation of bone char
(Elsevier, 2014-04-24)
The valorisation of animal wastes by pyrolysis has shown to be of interest, due to the versatility of the main compound of char, hydroxyapatite (HAP), which can be used in catalysis, electrochemistry, and adsorption. The ...
Systematic modeling of photovoltaic modules based on artificial neural networks
(Elsevier, 2016-06-03)
Using accurate models of photovoltaic modules is of major importance to make realistic simulations of these systems in order to study their elements for a better performance. In this paper we address the problem of the ...
Isotopic evidence for the reconstruction of diet and mobility during village formation in the Early Middle Ages: Las Gobas (Burgos, northern Spain)
(Springer, 2017-07-10)
Strontium, carbon, and nitrogen isotopes of human bone and tooth remains have been used to reconstruct residential mobility and diet of early medieval populations at Las Gobas from the sixth to eleventh centuries. Most ...
Dead horse, man-at-arms lost: cavalry and battle tactics in 15th century Castile
(Taylor & Francis, 2019-06-21)
For a long time historiography has stood up for Late Medieval
Castilian tactical backwardness with the insufficient research into
Castilian military tactics contributing to the persistence of old
paradigms. The aim of ...
Pitch Based Wind Turbine Intelligent Speed Setpoint Adjustment Algorithms
(MDPI, 2014-06)
This work is aimed at optimizing the wind turbine rotor speed setpoint algorithm. Several intelligent adjustment strategies have been investigated in order to improve a reward function that takes into account the power ...
Prediction of Aboveground Biomass from Low-Density LiDAR Data: Validation over P. radiata Data from a Region North of Spain
(MDPI, 2019-09-19)
Estimation of forestry aboveground biomass (AGB) by means of aerial Light Detection and Ranging (LiDAR) data uses high-density point sampling data obtained in dedicated flights, which are often too costly for available ...
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 ...
Sex of preceding sibling and anthropometrics of subsequent offspring at birth and in young adulthood: a population-based study in Sweden
(Wiley, 2014-05-13)
In many mammal species with sexual dimorphism producing sons is energetically more demanding to the mother than producing daughters. Although some studies in humans have suggested that offspring born after a brother have ...
Altered nuclear export signal recognition as a driver of oncogenesis
(AACR, 2019-10-01)
Altered expression of XPO1, the main nuclear export receptor in eukaryotic cells, has been observed in cancer, and XPO1 has been a focus of anticancer drug development. However, mechanistic evidence for cancer-specific ...
Preparation of a porous biochar from the acid activation of pork bones
(Elsevier, 2016-03-16)
A porous biochar was manufactured through the valorisation of waste pork bones, following a three-step process including pre-charring under mild conditions, acid treatment and thermal activation. The influence of the acid ...
