-
(Academic Press Inc., 2019)The design of effective incentive schemes that are both successful in motivating employees and keeping down costs is of critical importance. Research has demonstrated that prosocial incentives, where individuals’ effort ...
-
(John Wiley and Sons Inc., 2019)The primary aim of this study is to improve our understanding of therapists’ experience of a “difficult patient” and consider the different variables involved in this label. What makes a patient be perceived as difficult ...
-
(Elsevier B.V., 2019)Extreme precipitation events and multi-annual droughts, especially in arid to semi-arid subtropical regions, are among the most critical El Niño Southern Oscillation (ENSO) and global climate change impacts. Here, we assess ...
-
(MDPI AG, 2019)We studied and compared the nucleolar expression or nucleoli from specific bivalents in spermatocytes of the standard Mus musculus domesticus 2n=40, of Robertsonian (Rb) homozygotes 2n = 24 and heterozygotes 2n = 32. We ...
-
(Blackwell Publishing Ltd, 2019)Using data from Defense Meteorological Satellite Program 16–18, National Oceanic and Atmospheric Administration 15–19, and METOP 1–2 satellites, we reconstructed for the first time a two-dimensional statistical distribution ...
-
(Elsevier Ltd, 2019)Objectives: To evaluate the effect of addition of zinc oxide and copper nanoparticles (ZnO/CuNp) into universal adhesives, on antimicrobial activity (AMA), cytotoxicity (CTX), water sorption (WS) and solubility (SO), ...
-
(Springer New York LLC, 2019)While many studies have investigated consumer purchase behavior in reward programs, a better understanding of customer redemption behavior is lacking, particularly when promotions affect a core aspect of reward programs—free ...
-
New palladium (II) complexes containing phosphine-nitrogen ligands and their use as catalysts in ... (John Wiley and Sons Ltd, 2019)Aminocarbonylation of aryl halides, homogeneously catalysed by palladium, is an efficient method that can be employed for obtaining amides for pharmaceutical and synthetic applications. In this work, palladium (II) complexes ...
-
(Elsevier Ltd, 2019)A series of amphiphilic polymers bearing aliphatic secondary amines and hydroxyl groups have been synthesized showing different hydrophilic/hydrophobic balance. The synthesis is performed through the Paal-Knorr modification ...
-
(Elsevier GmbH, 2019)The independent toxic effects of copper and acetaminophen are among the most studied topics in liver toxicity. Here, in an animal model of Cebus capucinus chronically exposed to high dietary copper, we assessed clinical ...
-
(Institute of Physics Publishing, 2019)An important unsolved problem that affects practically all attempts to connect string theory to cosmology and phenomenology is how to distinguish effective field theories belonging to the string landscape from those that ...
-
(World Scientific Publishing Co. Pte Ltd, 2019)Fluid-mechanical and morphological parameters are recognized as major factors in the rupture risk of human aneurysms. On the other hand, it is well known that a lot of machine learning tools are available to study a variety ...
-
(Oxford University Press, 2019)Motivated by the advantages of observing at near-IR wavelengths, we investigate Type II supernovae (SNe II) as distance indicators at those wavelengths through the Photospheric Magnitude Method (PMM). For the analysis, we ...
-
(Elsevier S.A., 2019)By reaction of 2-aminofluorene with 2-pyridinecarboxaldehyde a new Schiff base (L) is obtained. The reaction of this ligand with Ag(I) and Cu(I) salts in different stoichiometry leads to the complexes [Ag(CF3SO3)(L)PPh3] ...
-
(Fundacao Cesgranrio, 2019)A democratizing and decentralized experience of educational change based on experimental education is analyzed. This experience integrated training, cultural and health aspects, the participation of the community and the ...
-
(Elsevier Ltd, 2019)In this study, the vibration behaviours of functionally graded microplates with cracks are investigated by means of a simple yet rigorous version of Mindlin's generialised continuum and the extended isogeometric analysis ...
-
(Elsevier B.V., 2019)In this work, the catalytic properties of Pt/MOx/TiO2 (M = Fe, Co) catalysts prepared by strong electrostatic adsorption (SEA), were investigated for the preferential oxidation (PROX) of CO in H2. The SEA method was chosen ...
-
(Elsevier B.V., 2019)The evolution of the magma plumbing system of the Pleistocene Apacheta-Aguilucho Volcanic Complex area (Altiplano-Puna Volcanic Complex, northern Chile) was investigated through petrographic, geochemical and isotopic studies ...
-
(Springer Verlag, 2019)Nearshore ichthyoplankton assemblages are constantly influenced by the dynamics of coastal environments (i.e. daily thermal gradients and coastal currents), as well as by regional environmental forcing, such as upwelling ...
-
(Institute of Physics Publishing, 2019)We explore the origins of the young B-type stars found by Casetti-Dinescu et al. at the outskirts of the Milky Way disk in the sky region of the Leading Arm of the Magellanic Stream. High-resolution spectroscopic observations ...
