Catalytic Enantioselective Synthesis of Tertiary Thiols From 5H-Thiazol-4-ones and Nitroolefins: Bifunctional Ureidopeptide-Based Brønsted Base Catalysis
(WILEY-VCH Verlag, 2013-09-17)
The direct catalytic reaction between an enolizable carbonyl compound and an electrophile under proton-transfer conditions has emerged as a challenging versatile transformation in organic synthesis.1 Over the last years ...
An Alternative Approach for the Incorporation of Cellulose Nanocrystals in Flexible Polyurethane Foams Based On Renewably Sourced Polyols
(Elsevier, 2016-11-16)
Este trabajo analiza tanto el efecto de los nanocristales de celulosa en las propiedades finales de espumas flexibles de poliuretano basadas en castor oil y maíz, sino que además se realiza un análisis en profundidad sobre ...
Association among obesity-related anthropometric phenotypes: analyzing genetic and environmental contribution
(Wayne State University Press, 2012-04-01)
Obesity has become a public-health and policy problem in many parts of the world. Epidemiological and population studies in this field are usually based on different anthropometric measures; however, common genetic and ...
Negotiation of Meaning Strategies in Child EFL Mainstream and CLIL Settings
(Wiley, 2016)
Research on child English as a second language (ESL) learners has shown the benefits of task-based interaction for the use of different negotiation of meaning (NoM) strategies, which have been claimed to lead to second ...
Use of native species to improve carbon sequestration and contribute towards solving the environmental problems of the timberlands in Biscay, northern Spain.
(Elsevier, 2013-03-15)
The rapid transformation of natural forest areas into fast-growing exotic species plantations, where the main objective is timber and pulp production, has led to a neglect of other services forests provide in many parts ...
A statistical investigation into the sharing of common genetic factors between blood pressure and obesity phenotypes in nuclear families from the Greater Bilbao (Spain)
(Lippincott, Williams & Wilkins, 2010)
Objectives: Several obesity phenotypes (e.g. body mass and fat, fat distribution) have been suggested to be a risk for elevated blood pressure. This study was undertaken to determine the heritability of four blood pressure ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
Computational Modelling of Three Different Sub-Boundary Layer Vortex Generators on a Flat Plate
(MDPI, 2018-11-10)
Flow separation is the source of several problems in a wind turbine including load fluctuations, lift losses, and vibrations. Vortex generators (VGs) are passive flow control devices used to delay flow separation, but their ...
Computational Characterization of a Rectangular Vortex Generator on a Flat Plate for Different Vane Heights and Angles
(MDPI, 2019-03-01)
Vortex generators (VG) are passive flow control devices used for avoiding or delaying the separation of the boundary layer by bringing momentum from the higher layers of the fluid towards the surface. The Vortex generator ...
Macrozooplankton predation impact on anchovy (Engraulis encrasicolus) eggs mortality at the Bay of Biscay shelf break spawning centre
(Oxford University Press, 2014-11-23)
A real-time PCR based method involving a species-specific probe was applied to detect Engraulis encrasicolus eggs predation by the macrozooplank-
ton community during the 2011 spawning season. Three locations along the ...
