-
(Springer Verlag, 2019)Carbon nanowalls were prepared on silicon substrates by radio frequency magnetron sputtering under an argon–hydrogen mixture, at different hydrogen fluxes and varying the substrate temperature and deposition times. Scanning ...
-
(MDPI AG, 2019)Due to the increase of the use of yeast derivatives (YDs) in winemaking to improve the technological and sensory properties in wines, in this work we evaluated the effect of the post-fermentation application of different ...
-
(Routledge, 2019)Use of subject scores as manifest variables to assess the relationship between latent variables produces attenuated estimates. This has been demonstrated for raw scores from classical test theory (CTT) and factor scores ...
-
(OSA - The Optical Society, 2019)Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. ...
-
(Public Library of Science, 2019)Identifying which ecosystem services are relevant to different stakeholders and understanding stakeholders’ perceptions of such services is useful for making informed decisions, especially in regions of the world where the ...
-
(Elsevier Ltd, 2019)Mass transference from lower to upper crustal levels requires an efficient network of pathways that act as channels for draining melts from the source and transferring magmas through the crust. We report on a mid-crustal ...
-
(Elsevier B.V., 2019)The equilibrium geometries and thermodynamic properties of anion vacancies in cadmium telluride, as predicted by density functional theory, are revisited using semilocal and hybrid density functionals. We find that stable ...
-
(ARAN Ediciones S.A., 2019)Objective: To evaluate a healthy food program for teachers and their educational transfer through an action plan for 3rd to 5th primary students, to improve their food habits and culinary skills. Methodology: A four months ...
-
(Bauru School of Dentistry, University of Sao Paulo, 2019)Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can ...
-
(IOS Press, 2019)Background: Intensive robot-assisted arm training in the chronic phase of stroke recovery can lead to clinical improvement. Combinatorial therapeutic approaches are sought to further optimize stroke recovery. Transcranial ...
-
(Institute of Electrical and Electronics Engineers Inc., 2019)This paper addresses the asymptotic behavior of a particular type of information-plus-noise-type matrices, where the column and row numbers of the matrices are large and of the same order, while signals have diverged and ...
-
(Elsevier Ltd, 2019)Intrinsic biological mechanisms transduce psychological stress into physiological adaptation that requires energy, but the role of mitochondria and mitochondrial DNA (mtDNA) in this process has not been defined in humans. ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)We obtain a closed-form formula for the quasi-stationary distribution of the classical Shiryaev martingale diffusion considered on the positive half-line [A, +∞) withA>0 fixed; the state space’s left endpoint is assumed ...
-
(Elsevier Ltd, 2019)Bioceramic nanoparticles have many potential applications within the biomedical device industry. However, these applications demand a precise control of their sizes, shapes and morphology which play a main role in most ...
-
(Elsevier B.V., 2019)An efficient method has been developed for the multiresidue and multiclass determination of 16 emerging contaminants (parabens, hormones, anti-inflammatory drugs, triclosan and bisphenol A) in water samples using rotating-disk ...
-
(Elsevier B.V., 2019)The late Mesozoic-Cenozoic evolution of the Central Andes of northern Chile consists of a series of events related to changing conditions along the plate margin, leading to different episodes of compression and extension. ...

(Sociedad Chilena de Nutricion Bromatologia y Toxilogica, 2019)Our objective was to explore families’ food provisioning strategies among households headed by working mothers in Santiago of Chile, through qualitative and ethnographical methods. We used in-depth individual interviews ...
-
(Routledge, 2020)The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine ...
