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 ... -
Preharvest sprays and their effects on the postharvest quality of fruit
(Stewart Postharvest Review, 2013-10)Purpose of review: This paper reviews studies on the effects of preharvest spray treatments on the postharvest quality and storage potential of fruits, with the objective of summarising the main effects in each case and ... -
Preparation and uses of chlorinated glycerol derivatives
(MDPI, 2020-05-28)Crude glycerol (C3H8O3) is a major by-product of biodiesel production from vegetable oils and animal fats. The increased biodiesel production in the last two decades has forced glycerol production up and prices down. ... -
Preparation of (S)-1-halo-2-octanols using ionic liquids and biocatalysts
(Molecular Diversity Preservation International, 2009)Preparation of (S)-1-chloro-2-octanol and (S)-1-bromo-2-octanol was carried out by the enzymatic hydrolysis of halohydrin palmitates using biocatalysts. Halohydrin palmitates were prepared by various methods from palmitic ... -
Prepartum blood lead concentrations linked to subsequent cyclicity in high-producing dairy cows in a non-industrial area
(Elsevier, 2016-09-01)This study sought to identify the possible presence of lead (Pb) in blood and if detected to examine the relationship between blood Pb concentrations during the transition period and subsequent reproductive performance in ... -
Prevalence of pesticides in postconsumer agrochemical polymeric packaging
(Elsevier, 2017)Pesticide remains contained in agrochemical packagingwaste are a source of uncontrolled risk for human health; they are also a quality feedstock for the plastic recycling industry.Many governments have recently started to ... -
