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 ... -
Plasma-Functionalized Isotactic Polypropylene Assembledwith Conducting Polymers for Bacterial Quantification byNADH Sensing
(Wiley-VCH Verlag, 2021)Rapid detection of bacterial presence on implantable medical devices isessential to prevent biofilm formation, which consists of densely packedbacteria colonies able to withstand antibiotic-mediated killing. In this work, ... -
Polymer inclusion membrane to access Zn speciation: Comparison with root uptake
(Elsevier, 2018)Metal speciation studies can be performed with a new technique based on a functionalized membrane. The estimation of not only the total amount of metal, but also the metal available to living organisms is very important. ... -
Porous Poly(3,4-ethylenedioxythiophene)-Based Electrodesfor Detecting Stress Biomarkers in Artificial Urine and Sweat
(Wiley, 2022)When danger is perceived, the human body responds to overcome obstacles and survive a stressful situation; however, sustained levels of stress are associated with health disorders and diminished life quality. Hence, ... -
Post-anthesis thermal stress induces differential accumulation of bioactive compounds in field-grown barley
(John Wiley & Sons, 2021)BACKGROUND: Barley (Hordeum vulgare L.) is a healthy grain because of its high content of dietary fibre and phenolic compounds. It faces periods of high temperature during grain filling, frequently reducing grain weight. ... -
Post-storage cell wall metabolism in two sweet cherry (Prunus avium L.) cultivars displaying different postharvest performance
(SAGE Publications, 2015)The biochemical processes underlying firmness loss of sweet cherry (Prunus avium L.) fruit are poorly understood.Studies on cell wall metabolism of sweet cherry have been generally undertaken during on-tree development or ... -
Postharvest heat and CO2 shocks induce changes in cuticle composition and cuticle-related gene expression in 'October Sun' peach fruit
(Elsevier, 2019)Fruit cuticles influence greatly postharvest quality of produce. Yet, few published studies have addressed changes in cuticle composition and related gene expression from a postharvest perspective, particularly for fruit ... -
