Novel and efficient biotechnological approach to produce 2,5-diformylfuran from biomass-derived 5-hydroxymethylfurfural
(American Chemical Society, 2021)The preparation of compounds of interest from biomass-derived 5-hydroxymethylfurfural (HMF) has attracted considerable attention. One such compound is 2,5-diformylfuran (DFF), obtained through oxidation of the hydroxyl ... -
Numerical Simulation of Non-Linear Models of Reaction—Diffusion for a DGT Sensor
(MDPI, 2020-04-20)In this work, we present a novel strategy for the numerical solution of a coupled system of partial differential equations that describe reaction–diffusion processes of a mixture of metals and ligands that can be absorbed ... -
Número de ciclos cortos necesarios para inducir la diapausa en huevos y larvas de Sesamia nonagrioides (Lefebvre)
(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 2000)Se sometieron huevos de Sesamia nonagrioides (LEFEBVRE) durante su desarrollo embrionario a fotoperiodo corto 12:12 (L:O) y posteriormente a fotoperiodos 16:8 y 0:24, sin observar que se hubiera inducido diapausa en ... -
Oligosaccharides: Defense Inducers, Their Recognition in Plants, Commercial Uses and Perspectives
(MDPI, 2020-12-16)Plants have innate immune systems or defense mechanisms that respond to the attack of pathogenic microorganisms. Unlike mammals, they lack mobile defense cells, so defense processes depend on autonomous cellular events ... -
Optimal sizing of a hybrid grid-connected photovoltaic and wind power system
(Elsevier, 2015-09)Hybrid renewable energy systems (HRES) have been widely identified as an efficient mechanism to generate electrical power based on renewable energy sources (RES). This kind of energy generation systems are based on the ... -
Optimal sizing of a hybrid grid-connected photovoltaic–wind–biomass power system
(MDPI, 2015)Hybrid renewable energy systems (HRES) are a trendy alternative to enhance the renewable energy deployment worldwide. They effectively take advantage of scalability and flexibility of these energy sources, since combining ... -
Optimización de la composición del atrayente sexual de Sesamia nonagrioides Lef.
(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 1992)Se describen una serie de ensayos de campo y laboratorio (pruebas de EAG, Electro-Anteno-Grama), para optimizar el tipo de trampa, la composición y la dosis de la mezcla atrayente, con miras a obtener un nivel máximo de ... -
Optimization and validation of PEF processing conditions to inactivate oxidative enzymes of grape juice
(Elsevier, 2007-12)White grape juice was processed using high intensity pulsed electric fields (PEF). The effect of this preservative technology on polyphenoloxidase (PPO) and peroxidase (POD) as well as on refractometric index, sugar content, ... -
Optimization of hyphenated asymmetric flow field-flow fractionation for the analysis of silver nanoparticles in aqueous solutions
(Springer, 2021-09-19)The extensive use of silver nanoparticles (AgNPs) in consumer products, medicine, and industry leads to their release into the environment. Thus, a characterization of the concentration, size, fate, and toxicity of AgNPs ... -
Panel consonance in the sensory evaluation of apple attributes: influence of mealiness on sweetness perception
(Wiley, 2008)Seventeen apple samples from nine different cultivars were evaluated by a trained panel of nine panelists. The first dimension of the raw principal component analysis models for each attribute (sweetness, sourness, ... -
Patterns of genetic and eco-geographical diversity in Spanish barleys
(Springer Verlag, 2008)The pool of Western Mediterranean landraces has been under-utilised for barley breeding so far. The objectives of this study were to assess genetic diversity in a core collection of inbred lines derived from Spanish barley ... -
Pb-binding to various dissolved organic matter in urban aquatic systems: key role of the most hydrophilic fraction
(Elsevier, 2011)Dissolved organic matter (DOM) from the treated effluent of a wastewater treatment plant and from the river Seine under high human pressure has been separated into three fractions: hydrophobic (containing humic and fulvic ... -
Photosynthesis-dependent/independent control of stomatal responses to CO2 in mutant barley with surplus electron transport capacity and reduced SLAH3 anion channel transcript
(Elsevier, 2015)The mechanisms of stomatal sensitivity to CO2 are yet to be fully understood. The role of photosynthetic and non-photosynthetic factors in stomatal responses to CO2 was investigated in wild-type barley (Hordeum vulgare ... -
Physicochemical measurements in ‘Mondial Gala®’ apples stored at different atmospheres: Influence on consumer acceptability
(Elsevier, 2008)Standard quality parameters, consumer acceptability, emission of volatile compounds and ethylene production of ‘Mondial Gala®’ apples (Malus × domestica Borkh.) were determined in relation to storage atmosphere, storage ... -
Plant volatiles challenge inhibition by structural analogs of the sex pheromone in Lobesia botrana (Lepidoptera: Tortricidae)
(Czech Academy of Sciences. Institute of Entomology of the Biology Centre, 2016)Plant volatiles can synergize the response to moth pheromone. Synthetic pheromone analogs, in turn, have the opposite effect in reducing pheromone attractiveness. To determine how these two types of stimuli interact and ... -
