Assessment of green approaches for the synthesis of physically crosslinked lignin hydrogels
(Elsevier, 2019-09-28)
Lignin is an excellent candidate to be used as a starting material for hydrogel synthesis due to its highly functional character. The exhaustible character of the fossil resources linked to the increase of plastic residues ...
A Data-Driven Reaction Network for the Fluid Catalytic Cracking of Waste Feeds
(MDPI, 2018-11-27)
Establishing a reaction network is of uttermost importance in complex catalytic processes such as fluid catalytic cracking (FCC). This step is the seed for a faithful reactor modeling and the subsequent catalyst re-design, ...
Editors versus audiences facing news: Is this discrepancy also repeated on social news networks?
(SAGE Publications, 2019-06-04)
This study examines whether the frequent discrepancy between publishers and audiences over the news that interests them – the former preferring hard news, the latter soft news – is repeated on social networks. Based on a ...
Depolymerization of different organosolv lignins in supercritical methanol, ethanol and acetone to produce phenolic monomers
(ACS, 2015-12-18)
Olive tree pruning was delignified by organosolv processes (acetosolv, formosolv and acetosolv/formosolv) to extract different lignins. The obtained lignins (acetosolv lignin (AL), formosolv lignin (FL) and acetosolv/formosolv ...
Detecting depression in medically ill patients: comparative accuracy of four screening questionnaires and physicians' diagnoses in Spanish population
(2010-10)
Objective: To compare the diagnostic accuracy of four depression screening tools commonly used in patients with medical disorders, relative to a reference diagnostic standard – a structured psychiatric interview.
Methods: ...
Angle of loll calculation by cubic spline
(Spanish Society of Maritime Research (SEECMAR), 2013)
Several years ago the Basque Government supported the programming of the software ARKITSAS in order to provideall existing vessels with a specific software to calculate stability, cargo and longitudinal strength data. The ...
Effect of microwave heating damage on the electrical, thermal and mechanical properties of fibre-reinforced cement mortars
(Elsevier, 2018)
Nowadays, refurbishing of existing structures has gained interest in order to reduce both the construction materials used and the construction and demolition waste production. For that purpose, there are several methods ...
Effect of the photocatalytic activity of TiO2 on lignin depolymerization
(Elsevier, 2013-05)
Lignin is a good candidate for photocatalytic cracking due to the presence of hydroxyl groups. The photocatalytic cracking reaction involves TiO2 as heterogeneous catalyst.
In the present work lignin obtained by two ...
Communicative anxiety in English as a third language
(Taylor & Francis, 2015-11-10)
The present study focuses on the link between three factors, proficiency,
language certificates and bilingualism, and levels of communicative
anxiety in the third language (English) in two groups of adult users,
university ...
Dysfunctional and compensatory duality in mild cognitive impairment during a continuous recognition memory task
(Elsevier, 2012-11-23)
One of the current issues of debate in the study of mild cognitive impairment (MCI) is deviations of oscillatory brain responses from normal brain states and its dynamics. This work aims to characterize the differences of ...
