Une synthèse sur la restauration fluviale dans le bassin de l’Ebre
(Université de Toulouse, 2017)
[FR]L’état écologique et la fonctionnalité des cours d’eau du bassin de l’Èbre ont subi une détérioration remarquable au cours des dernières décennies, à cause du changement global et des pressions anthropiques directes. ...
Quantifying wheelchair basketball match load: a comparison of heart-rate and perceived-exertion methods.
(Human Kinetics, 2016-05)
Purpose: To describe the objective and subjective match load (ML) of wheelchair basketball (WB) and determine the relationship between session heart-rate (HR) -based ML and rating-of-perceived-exertion (RPE) -based ML ...
Simultaneous catalytic de-polymerization and hydrodeoxygenation of lignin in water/formic acid media with Rh/Al2O3, Ru/Al2O3 and Pd/Al2O3 as bifunctional catalysts
(Elsevier, 2015-04-28)
[EN] The catalytic solvolysis of 3 lignins of different sources in a formic acid/water media using bifunctional Ru/Al2O3, Rh/Al2O3, Pd/Al2O3 catalysts was explored in a batch set-up at different temperatures and reaction ...
Synthesis of novel antiproliferative hybrid bis-(3-indolyl)methane phosphonate derivatives
(Elsevier, 2018-09-15)
An efficient synthetic methodology for the preparation of phosphorus substituted bis-(3-indolyl)methane through a double nucleophilic addition of indole derivatives to an in situ generated α-iminophosphonate is reported. ...
Synthesis of novel hybrid quinolino[4,3-b][1,5]naphthyridines and quinolino[4,3-b][1,5]naphthyridin-6(5H)-one derivatives and biological evaluation as topoisomerase I inhibitors and antiproliferatives
(Elsevier, 2020-04-03)
The topoisomerase I enzymatic inhibition of hybrid quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridines and quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-ones ...
Novel phosphine sulphide gold(I) complexes: topoisomerase I inhibitors and antiproliferative agents
(RSC, 2020-05-20)
This work describes the synthesis of the gold(I) complexes of phosphine sulphides. The formation of these new derivatives has been confirmed by X-ray crystallography. The coordination of gold(I) with the sulphur atom of ...
Shortcut to equilibration of an open quantum system
(American Physical Society (APS), 2019-06-26)
We present a procedure to accelerate the relaxation of an open quantum system towards its equilibrium state. The control protocol, termed the shortcut to equilibration, is obtained by reverse-engineering the nonadiabatic ...
Urinary arsenic speciation in children and pregnant women from Spain
(Springer, 2017)
Inorganic arsenic (i-As) is a non-threshold human carcinogen that has been associated with several adverse health outcomes. Exposure to i-As is of particular concern among pregnant women, infants and children, as they are ...
