Mechanism of action of nitrification inhibitors based on dimethylpyrazole: A matter of chelation
(Elsevier, 2020-08-22)
In agriculture, the applied nitrogen (N) can be lost in the environment in different forms because of microbial transformations. It is of special concern the nitrate (NO3−) leaching and the nitrous oxide (N2O) emissions, ...
Renewable biopolyols from residual aqueous phase resulting after lignin precipitation
(ACS, 2021-02-19)
The aim of this work was to obtain two biopolyols from the liquid residue resulting from the precipitation of lignin contained in two different black liquors, Eucalyptus globulus organosolv black liquor (EOBL) and Pinus ...
Removable biobased waterborne Pressure-Sensitive Adhesives containing mixtures of isosorbide methacrylate monomers
(ACS, 2020-05-22)
Growing environmental concerns are enforcing sustainable recycling processes for glass substrates, especially bottles, where a fast cleaning and minimization of the use of solvents is desired. In this process, labels and ...
Recyclable, remendable and healing polyurethane/acrylic coatings from UV curable waterborne dispersions containing Diels-‐Alder moieties
(Elsevier, 2020-02-01)
The aim of the present work is to increase the sustainability of UV curable waterborne polyurethane dispersions using the Diels-Alder chemistry. In this way, the obtaining of crosslinked polyurethane coatings presenting ...
Restoration of the electrocardiogram during mechanical cardiopulmonary resuscitation
(IOP, 2020-04-04)
Objective: An artefact-free electrocardiogram (ECG) is essential during cardiac arrest to decide therapy such as defibrillation. Mechanical cardiopulmonary resuscitation (CPR) devices cause movement artefacts that alter ...
Motives for the Use or Not of Protective Equipment for the Recreational Practice of Skiing and Snowboarding in Spanish Winter Stations
(MDPI, 2021-12-20)
The objective of this research was to analyze the motives for using or not using protections by recreational ski and snowboard athletes, specifically regarding gender and age in the winter resorts of Sierra Nevada and Alto ...
Multimodal Algorithms for the Classification of Circulation States during Out-of-Hospital Cardiac Arrest
(IEEE, 2020-10-12)
Goal: Identifying the circulation state during
out-of-hospital cardiac arrest (OHCA) is essential to determine
what life-saving therapies to apply. Currently algorithms
discriminate circulation (pulsed rhythms, PR) from ...
Minimum spouting velocity of fine particles in fountain confined conical spouted beds
(Elsevier, 2020-07-25)
[ES] Se ha desarrollado un novedoso dispositivo interno denominado confinador de la fuente, que estabiliza el sistema y permite operar con partículas finas, incluso sin ningún tipo de tubo central. Dada la estabilidad que ...
Numerical study of a turbulent co-axial non-premixed flame for methanol hydrothermal combustion: Comparison of the EDC and FGM models
(Elsevier, 2021-02-01)
Eddy dissipation concept (EDC) model and flamelet generated manifolds (FGM) model are developed separately to study the temperature profiles and extinction limits of non-premixed hydrothermal flames. Predictions by the two ...
Numerical assessment of the analytical models used to determine flexural and shear moduli in I-Beams when the tensile and compressive moduli are different
(Elsevier, 2020-01-30)
The different compressive and tensile moduli of fibre reinforced composites have been considered in the analysis of the flexural and shear moduli of I-beams. Firstly, the neutral axis has been determined analytically and ...
