Bonding strength of stainless steel rebars in concretes exposed to marine environments
(Elsevier, 2018-05-30)
[EN] Many studies have corroborated the use of Stainless Steel Reinforcements (SSR) for structures in corrosive environments. However, even though the conditions for their employment are specified in different standards, ...
A real-time stress classification system based on arousal analysis of the nervous system by an F-state machine
(Elsevier, 2017-09-01)
Background and objective: Detection and labelling of an increment in the human stress level is a con- tribution focused principally on improving the quality of life of people. This work is aimed to develop a biophysical ...
Classification of archaeological pieces into their respective stratum by a chemometric model based on the soil concentration of 25 selected elements
(Elsevier, 2010-04-01)
The aim of this work was to demonstrate that an archaeological ceramic piece has remained buried underground in the same stratum for centuries without being removed. For this purpose, a chemometric model based on Principal ...
Assessing the effect of alternative land uses in the provision of water resources: Evidence and policy implications from southern Europe
(Elsevier, 2012-10-01)
Ecosystem goods and services have been brought to the forefront of policy making all over the world. It is acknowledged that these goods and services underpin human well-being. The provision of water resources is amongst ...
Chicken feathers as a natural source of sulphur to develop sustainable protein films with enhanced properties
(Elsevier, 2017-08-05)
In this work, the effect of hydrolyzed keratin on the properties of soy protein-based films was analyzed when different manufacture processes were employed. It is widely known that the processing method selected can affect ...
Block copolymer concentration gradient and solvent effects on nanostructuring of thin epoxy coatings modified with epoxidized styrene-butadiene-styrene block copolymers
(ACS, 2012-01-27)
The gradient on block copolymer concentration through film thickness as well as the effects of casting solvents used on the nanostructuring of a thermosetting epoxy coating modified with an epoxidized poly(styrene-b-buta ...
Characterization of the first PCSK9 gain of function homozygote
(Elsevier / American College of Cardiology, 2015-11)
Gain of function (GOF) mutations in proprotein convertase subtilisin kexin type 9 (PCSK9) are a rare cause of familial hypercholesterolemia (FH). We identified a child with a clinical diagnosis of FH with 2 novel putative ...
A versatile synthetic approach to design tailor-made push-pull chromophores with intriguing and tunable photophysical signatures
(Elsevier, 2017-08-12)
Novel modified Biellmann BODIPYs were prepared using a C-H arylation reaction with in-situ formed
aryldiazonium salts. The post-functionalization of the methylthio group of these derivatives was
demonstrated in SNAr and ...
Accuracy analysis of complete-arch digital scans in edentulous arches when using an auxiliary geometric device
(Elsevier, 2019-03-31)
Statement of problem. Obtaining reliable digital scans of edentulous patients is challenging
because of the absence of anatomic landmarks/geometric variations along the dental arch. Whether
adding an auxiliary geometric ...
A Note on the Normalization of Spanish Electricity Spot Prices
(IEEE, 2015-07-21)
Merit order of renewable generation has produced
an increasing, relevant number of zero values in Spanish electricity
spot prices since 2010, in contrast with the rest of markets
which rarely present zero values. This ...
