Exceptional performance of gold supported on fluoridated hydroxyapatite catalysts in CO-cleanup of H2-rich stream: High activity and resistance under PEMFC operation conditions
(Elsevier, 2021-03-17)
Proton-exchange-membrane fuel cells (PEMFCs) appear to be the most promising solution for future automotive applications. Facing the lack of efficient hydrogen storage and transportation solutions, current research is ...
Task modality and languagerelated episodes in young learners: An attempt to manage accuracy and editing
(Sage, 2021-10-22)
Task modality (oral vs. writing) has been found to affect the production, nature and
resolution of the language-related episodes (LREs) produced by adult learners in collaborative
interaction, a finding also attested in ...
Influence of Nb on Ti Diffusion in Gamma-TiAl Intermetallics Studied by Mechanical Spectroscopy
(Elsevier, 2021-01-25)
The development of intermetallic titanium aluminides has been driven by the aeronautic and aerospace industries because of the excellent mechanical properties and low density of gamma-TiAl based alloys. Up to now, several ...
Physical Activity, Sedentary Behavior, and Sleep Quality in Adults with Primary Hypertension and Obesity before and after an Aerobic Exercise Program: EXERDIET-HTA Study
(MDPI, 2020-08-17)
Background: The purposes of the study were to: analyze, by objective (accelerometry) and subjective (International Physical Activity Questionnaire, IPAQ) methodologies, the physical activity (PA) and sedentary behavior ...
Impact of β-Blockers on Heart Rate and Oxygen Uptake During Exercise and Recovery in Older Patients With Heart Failure With Preserved Ejection Fraction
(Lippincott, Williams & Wilkins, 2020-05)
Purpose: The study aimed to investigate the differences in oxygen uptake ((Equation is included in full-text article.)O2) and heart rate (HR) (at rest, submaximal exercise, peak exercise, and recovery) in patients with ...
Optimisation of bimetallic Co-Ni supported catalysts for oxidation of methane in natural gas vehicles
(Elsevier, 2020-11-21)
This work deals with the extensive study of supported bimetallic Co-Ni catalysts for the complete oxidation of methane. The simultaneous incorporation of nickel and cobalt was found to enhance the redox properties by ...
Partial privatization in an international mixed oligopoly under product differentiation
(Springer-Verlag, 2020-05-16)
[EN]We consider an international mixed market that comprises two countries, each of
which owns one public firm and one private firm. As a benchmark case, we consider
a single country that owns all four firms. In both ...
Disclosure of R&D knowledge in a mixed duopoly
(John Wiley & Sons Ltd., 2020-01-03)
[EN]In this paper, we analyze whether firms want to disclose their R&D knowledge for free in a mixed duopoly. We extend the paper by Poyago-Theotoky (1999) on strategic R&D with endogenous spillovers by considering a mixed ...
A physiological approach to study the competition ability of the grassland species Trifolium pratense and Agrostis capillaris
(Elsevier, 2020-09-19)
(EN) The response of plant species to external factors depends partly on the interaction with the environment and with the other species that coexist in the same ecosystem. Several studies have investigated the main traits ...
Loop decay in Abelian-Higgs string networks
(APS. American Physical Society, 2021-08-16)
We study the decay of cosmic string loops in the Abelian-Higgs model. We confirm earlier results that loops formed by intersections of infinite strings formed from random-field initial conditions disappear quickly, with ...
