Separation and Purification of Hemicellulose by Ultrafiltration
(ACS, 2011-12-29)
[EN]During hydrolysis treatments, where the main objective is the solubilization of hemicelluloses, several undesirable reactions may occur. As a result, monomeric sugars and nonsaccharide compounds are obtained in the ...
Self-compacting concrete incorporating electric arc-furnace steelmaking slag as aggregate
(Elsevier, 2016-11-17)
Electric arc-furnace slag (EAFS) is an industrial by-product that can be employed in hydraulic mixes used in the field of construction and civil engineering. The design and preparation of self-compacting mixes with this ...
Proteolytic Degradation of Hippocampal STEP61 in LTP and Learning
(Springer Nature, 2018-06-12)
Striatal-enriched protein tyrosine phosphatase (STEP) modulates key signaling molecules involved in synaptic plasticity and neuronal function. It is postulated that STEP opposes the development of long-term potentiation ...
Sensitiveness of the ratio between monovacancy and bulk positron lifetimes to the approximations used in the calculations: Periodic behaviour
(Elsevier, 2012-05-09)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic structure ...
Shortcuts to adiabaticity in three-level systems using Lie transforms
(APS, 2014-05-07)
Sped-up protocols that drive a system quickly to the same populations that can be reached by a slow adiabatic process may involve Hamiltonian terms which are difficult to realize. We use the dynamical symmetry of the ...
Simulations of water nano-confined between corrugated planes
(AIP, 2017-11-21)
[EN] Water confined to nanoscale widths in two dimensions between ideal planar walls has been the subject of ample study, aiming at understanding the intrinsic response of water to confinement, avoiding the consideration ...
Simultaneous detection of the spin-Hall magnetoresistance and the spin-Seebeck effect in platinum and tantalum on yttrium iron garnet
(Americal Physical Society, 2014-11-26)
The spin-Seebeck effect (SSE) in platinum (Pt) and tantalum (Ta) on yttrium iron garnet has been investigated by both externally heating the sample (using an on-chip Pt heater on top of the device) and by current-induced ...
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. ...
