Enhancing ventilation detection during cardiopulmonary resuscitation by filtering chest compression artifact from the capnography waveform
(Public Library Science, 2018-08-02)
Background
During cardiopulmonary resuscitation (CPR), there is a high incidence of capnograms distorted by chest compression artifact. This phenomenon adversely affects the reliability of automated ventilation detection ...
Bee-Plant Relationship in Early Childhood: A Study through the Analysis of Children’s Drawings
(MDPI, 2018-10-30)
Bees play a key role for humans, since crops pollination relies heavily on them. However, bees’ population is diminishing dramatically. Therefore, conservation actions are needed to protect them, including educational ones. ...
Cohomological tautness of singular Riemannian foliations
(Springer, 2018-11-16)
For a Riemannian foliation F on a compact manifold M, J. A. Alvarez Lopez proved that the geometrical tautness of F, that is, the existence of a Riemannian metric making all the leaves minimal submanifolds of M, can be ...
Academic performance and school engagement among secondary school students in accordance with place of birth, gender and age
(European Journal of Education and Psychology (E J E P), 2018)
[EN] One of the most pressing concerns today in our society is how to ensure that students are able to adapt to the ever-changing context in which they live, and one of the ways of achieving this is to ensure good school ...
The role of parental socialization styles in school engagement and academic performance
(European Journal of Education and Psychology (E J E P), 2018)
[EN] Many variables have been analyzed in relation to school adjustment. However, only a few studies have explored the relationship between this construct and parental socialization styles, particularly in Spain. This work ...
A Charge-Transfer Salt Based on Ferrocene/Ferrocenium Pairs and Keggin-Type Polyoxometalates
(MDPI, 2018-11-30)
A new hybrid inorganic-organometallic salt has been obtained from the reaction of the Keggin-type silicotungstate anion with ferrocene in a water/methanol mixture as a result of the partial oxidation of ferrocene molecules ...
FeCrAlloy Monoliths Coated with Ni/Al2O3 Applied to the Low-Temperature Production of Ethylene
(MDPI, 2018-07)
This paper investigates the oxidative dehydrogenation of ethane to produce ethylene at low temperatures (500 degrees C) in metallic structured substrates. To check this point, the FeCrAlloy (R) monoliths with different ...
A new overhang constraint for topology optimization of self-supporting structures in additive manufacturing
(Springer, 2018-11)
This work falls within the scope of computer-aided optimal design, and aims to integrate the topology optimization procedures and recent additive manufacturing technologies (AM). The elimination of scaffold supports at the ...
Flexible Abrasive Tools for the Deburring and Finishing of Holes in Superalloys
(MDPI, 2018-12-06)
Many manufacturing sectors require high surface finishing. After machining operations such as milling or drilling, undesirable burrs or insufficient edge finishing may be generated. For decades, many finishing processes ...
Graphene oxide enhances alginate encapsulated cells viability and functionality while not affecting the foreign body response
(Taylor & Francis, 2018-05-21)
The combination of protein-coated graphene oxide (GO) and microencapsulation technology has moved a step forward in the challenge of improving long-term alginate encapsulated cell survival and sustainable therapeutic protein ...
