Testing of self-similarity and helical symmetry in vortex generator flow simulations
(Wiley, 2016-06)
Vortex generators (VGs) are used increasingly by the wind turbine industry as flow control devices to improve rotor blade
performance. According to experimental observations, the vortices generated by VGs have previously ...
Obtaining reliable intraoral digital impressions for an implant-supported complete-arch prosthesis: A dental technique
(2019-02-28)
This article describes a technique for obtaining an accurate complete-arch digital scan for an edentulous patient. To achieve this, an auxiliary polymeric device that simulates a denture is designed, fabricated, and placed ...
Field assessment of thermal behaviour of social housing apartments in Bilbao, Northern Spain
(Elsevier, 2013-06-26)
A field study of 10 social housing dwellings in the north of Spain is presented in this paper. Knowing the building stock is the first step to set up priorities in a global strategy to improve the energy efficiency of the ...
UV screening clear coats based on encapsulated CeO2 hybrid latexes
(RSC, 2012-12-21)
CeO2 nanoparticles have been successfully incorporated into acrylic latex particles with an excellent homogeneous distribution (mostly one inorganic particle per polymer particle) and limited aggregation (inorganic ...
The effect of the carboxylation degree on cellulose nanofibers and waterborne polyurethane/cellulose nanofiber nanocomposites properties
(Elsevier Ltd., 2020-03)
[EN] There has been an exponential rise in the interest for waterborne polyurethanes (WBPU), due to the easy customizability of their properties and their ecofriendly nature. Moreover, their aqueous state facilitates the ...
One pot stimuli-responsive linear waterborne polyurethanes via Diels-Alder reaction
(Elsevier, 2019-01-25)
Different strategies were used to obtain waterborne polyurethanes containing Diels-Alder moieties. In the first one (two pot), furan and maleimide end capped waterborne polyurethane dispersions were synthesized with the ...
The effect of the size of the board of directors on corporate social performance: A meta-analytic approach
(Wiley, 2020-04-15)
This paper examines the influence of the size of firms' board of directors on corporate social performance through a meta-analytic perspective. To that end, a sample of 80 articles that draw on evidence from more than ...
The T1D-associated lncRNA Lnc13 modulates human pancreatic β cell inflammation by allele-specific stabilization of STAT1 mRNA
(National Academy of Sciences, 2020-03-05)
The vast majority of type 1 diabetes (T1D) genetic association signals lie in non-coding regions of the human genome. Many have been predicted to affect the expression and secondary structure of long non-coding RNAs ...
Micro-Raman spectroscopic identification of natural mineral phases and their weathering products inside an abandoned zinc/lead mine
(Elsevier, 2011-01-23)
Mining activities provide a good source of minerals of different nature. On the one hand, the primary minerals for whose formation a geological time-scale is required. On the other hand, secondary minerals, formed from ...
Operating conditions for attenuating Ni/La2O3-αAl2O3 catalyst deactivation in the steam reforming of bio-oil aqueous fraction
(Elsevier, 2013-07-16)
A study was carried out on the effect of temperature (in the 500–800 °C range) and space–time (between 0.10 and 0.45 gcatalyst h(gbio-oil)− 1) on Ni/La2O3–αAl2O3 catalyst deactivation by coke deposition in the steam reforming ...
