The word order of negation in the history of Basque: A linguistic and sociolinguistic approach
(John Benjamins, 2021-02-01)
This article investigates word order changes in negated periphrastic constructions in the history of Basque. A number of linguistic variables are argued to correlate with these changes: the negative particle ez is increasingly ...
The supply of ceramics to Portuguese north African strongholds in the 15th and 16th centuries: new archaeometric data from Ksar Seghir and Ceuta
(Elsevier, 2021-03-23)
The present study aims to present new archaeometric data from a wide typological rank of ceramics collected in Ksar Seghir (Morocco) and Ceuta (Spain), two different archaeological sites in the south bank of the Strait of ...
The intrinsic effect of co-feeding water on the formation of active/deactivating species in the methanol-to-hydrocarbons reaction on ZSM-5 zeolite
(Royal Society Chemistry, 2021-02-21)
Water is formed and added in the conversion of methanol-to-hydrocarbons, slowing down both the reaction and deactivation rates. This work aims to clarify the selective nature of water quenching on a ZSM-5 zeolite catalyst ...
The Six Isomers of the Cyclohexanol Dimer: A Delicate Test for Dispersion Models
(Wiley, 2020)
The cyclohexanol homodimer acts as a delicate test model of the role of dispersion forces in intermolecular association. Whereas phenol produces a single dimer, the suppression of π interactions and the larger conformational ...
The commemoration of children in the funerary epigraphy of the Conventus Cluniensis (Hispania Citerior)
(University Toronto Press, 2021-12-07)
This paper examines the funerary inscriptions dedicated to children in the Roman
period. The rate of infant mortality was high in this period but only a low percentage of
inscriptions were dedicated ...
Phosphonium-based ionic liquids: Economic and efficient catalysts for the solvent-free cycloaddition of CO2 to epoxidized soybean vegetable oil to obtain potential bio-based polymers precursors
(Elsevier, 2021-09-25)
A series of phosphonium-based ionic liquids have been prepared in one step in a simple way from inexpensive feedstocks. The prepared ionic liquids have been successfully tested as catalysts in the solvent-free cycloaddition ...
Performance Analysis in Football-Specific Tests by Para-Footballers With Cerebral Palsy: Implications for Evidence-Based Classification
(Human Kinetics, 2021-03-21)
Purpose: The objectives of this study were to analyze whether there were differences among para-footballers with different types and degrees of brain impairment (ie, bilateral spasticity, athetosis/ataxia, unilateral ...
Photoswitchable catalysis using organometallic complexes
(Royal Society of Chemistry, 2020-04-30)
This review describes the state of the art in photoswitchable organometallic catalysis, underlining the importance of ligand design. The implementation of spatio-temporal control on known catalytic processes
has been ...
Performance of a superconducting breaker for the protection of HVDC grids
(Institution of Engineering and Technology (IET) in partnership with Wiley, 2020-02-18)
Future multi-terminal high-voltage direct current (HVDC) grids will be essential for the electric power system expansion. However, there are still several technical, economic and legal obstacles that interfere with the ...
