Recently, new bioactive compounds were identified in olive oil, lipophenols, which are composed of a fatty acid (FA) and a phenolic core, such as HT (HT-FA). However, their bioaccessibility remains unknown. Thus, the present study uncovers the impact of the separate phases of gastrointestinal digestion on the release and stability of HT-FAs from oily matrices under in vitro simulated conditions. Accordingly, it was found that the bioaccessibility of HT derivatives is largely dependent on the...

We consider two types of optimal foragers: a random searcher and a search image user. A search image user can find its desired prey with higher and undesired prey with lower probability than a random searcher. Our model considers the density-dependent travelling time and the time duration of reproduction (oviposition). In the framework of optimal foraging theory for one predator–two prey systems, we find that there are ranges of prey densities in which the search image user has a higher net...

For compact metric spaces (X,d), we show that the Lipschitz spaces Lip(X,d) and the little Lipschitz spaces lip(X,d^α) with 0 < α < 1, equipped with the sum norm, support only trivial hermitian operators, that is, real multiples of the identity operator.

Each level is presented, along with an analysis of its benefits and limitations. Next, this analysis...

The study of the evolution of financial series has always been a complex problem because of the nature of stock market series that usually are close to a random walk. The most usual approach has been to apply ARCH and GARCH models, as well as methods that attempt to capture stochastic volatility. In this paper we present an alternative way of approximating this problem, that consists of modeling these series by functional principal components analysis of the financial process up to a certain...

This paper addresses the problem of integrating observational and interventional datasets, potentially biased, to compute counterfactuals in structural causal models. We present a causal expectation-maximization scheme (EMCC) that approximates bounds for partially identifiable counterfactual queries under selection bias. We show that the data likelihood has no local maxima, enabling efficient EMCC implementation for non-identifiable queries. The approach extends to multiple datasets by mapping...

This paper focuses on the study of child poverty in the 28 Member States of the European Union over the period 2008–2018. We analyse the relationship between child poverty and government social expenditure by controlling it with tax structure (ratio direct taxes over indirect taxes), economic growth and socio-...

Atmospheric factors, such as clouds, wind, dust, or aerosols, play an important role in the power generation of photovoltaic (PV) plants. Among these factors, soiling has been revealed as one of the most relevant causes diminishing the PV yield, mainly in arid zones or deserts. The effect of soiling on the PV performance can be analyzed by means of I–V curves measured simultaneously on two PV panels: one soiled and the other clean. To this end, two I–V tracers, or one I–V tracer along with a...

The use of microbial inoculants, particularly arbuscular mycorrhizal fungi, has great potential for sustainable crop management, which aims to reduce the use of chemical fertilizers and pesticides. However, one of the major challenges of their use in agriculture is the variability of the inoculation effects in the field, partly because of the varying environmental conditions. Light intensity and quality affect plant growth and defense, but little is known about their impacts on the benefits of...

Municipal solid waste and sewage sludge are produced in large quantities that are often managed through industrial composting treatment.

In this study, the operations of six industrial composting facilities that process municipal solid waste and sewage...

The industrial viability of two emerging technologies for CO2 capture from flue gases, i.e., adsorption in porous commercial zeolites and biomass production by microalgae, is compared. Our study is organized in two steps: first, the best system is selected (either zeolite type or microalgae strain). Second, their performance is quantified and their advantages at real conditions discussed. For the physicochemical process, we find that commercial zeolite MFI is the best choice for CO2 capture...

Pulsed Electric Field (PEF) pre-treatment, applied on fresh microalgae Auxenochlorella protothecoides, induces spontaneous release of a substantial water fraction and enables subsequent lipid extraction using ethanol-hexane blends. In this study, fresh microalgae suspensions were treated with PEF and incubated under inert conditions. Incubation promotes the release of ions and carbohydrates and increases the yields of subsequent lipid extraction thus enabling a considerable reduction of PEF-...

Microalgae are becoming an important source of high-value products such as biostimulants, biopesticides, and other low-value products like biofertilizers or aquafeed (fatty acids and carotenoids) among others. However, extracting the biomolecules contained in the microalgae cells is difficult due to the structure and composition of the microalgal cell wall. To overcome this drawback, mechanical cell disruption methods such as high-pressure homogenization (HPH), can be applied to facilitate...

The objective of this study was to...

Although the relationship between stereotypes and acculturation preferences has been previously studied from the majority perspective among adults, the perspective of adolescents and minority groups is understudied. This research analyzed the contribution of four stereotype dimensions (i.e., morality, immorality, sociability, and competence) to the acculturation preferences of Spanish adolescents and adolescents of Moroccan-origin, the moderating role of stereotypes in intergroup acculturation...

The present research examined if the time needed to implement expectancy-based strate-gic processes is different in younger and healthy older adults. In four experiments partici-pants from both age groups performed different strategic priming tasks. These included a greater proportion of incongruent (or unrelated; 80%) than of congruent (or related; 20%) tri-als. With this procedure performance is worse for congruent (less frequent) than for incon-gruent (more frequent) trials, thus...

This article discusses the literary similarities between Doris Lessing's Love, Again (1995) and Rosa Montero's La carne (2016), emphasising the parallels between these writers’ interest in women’s ageing experiences and the role that the main characters in both of these novels play in the contemporary cultural scene. Of particular interest for this analysis is the experience of these two female authors, whose novels were written in historical periods that are marked by major social...

Natural disasters, especially those related to water—like storms and floods—have increased over the last decades both in number and intensity. Under the current Climate Change framework, several reports predict an increase in the intensity and duration of these extreme climatic events, where the Mediterranean area would be one of the most affected. This paper develops a decision support system based on Bayesian inference able to predict a flood alert in Andalusian Mediterranean catchments. The...

In the past two decades, the traditional nosology of attention-deficit/hyperactivity disorder (ADHD) has been criticized for having insufficient discriminant validity. In line with current trends, in the present study, we combined a data-driven approach with the advantages of virtual reality aiming to identify novel behavioral profiles of ADHD based on ecological and performance-based measures of inattention, impulsivity, and hyperactivity. One hundred and ten Spanish-speaking participants (6-...

During the last years, the study of fuzzy database query languages has attracted the attention of many researchers. In this line of research, our group has proposed and developed FSA-SPARQL (Fuzzy Sets and Aggregators based SPARQL), which is a fuzzy extension of the Semantic Web query language SPARQL. FSA-SPARQL works with fuzzy RDF datasets and allows the definition of fuzzy queries involving fuzzy conditions through fuzzy connectives and aggregators. However, there are two main challenges to...

Current food systems have significant negative environmental, social, and economic impacts. Externalized costs and benefits create false market incentives favoring less healthy and unsustainable options. Transitioning to sustainable agri-food systems requires that businesses internalize these externalities. Internalization of externalities (IOE) is often addressed through policy measures and regulatory initiatives. However, IOE can also be carried out through business models (BMs) and...

Background: Beyond the massive amounts of DNA and genes transferred from the protoorganelle genome to the nucleus during the endosymbiotic event that gave rise to the plastids, stretches of plastid DNA of varying size are still being copied and relocated to the nuclear genome in a process that is ongoing and does not result in the concomitant shrinking of the plastid genome. As a result, plant nuclear genomes feature small, but variable, fraction of their genomes of plastid origin, the so-...
