The role of post-transcriptional modulators of metalloproteins in response to metal deficiencies
2021
Copper and iron proteins play a wide range of functions in living organisms. Metal assembly into metalloproteins is a complex process, where mismetalation is detrimental and energy-consuming to cells. Under metal deficiency, metal distribution is expected to reach a metalation ranking, prioritizing essential versus dispensable metalloproteins, while avoiding interferences with other metals and protecting metal-sensitive processes. In this review, we propose that posttranscriptional Modulators of Metalloprotein messenger RNA (ModMeR) are good candidates in metal prioritization under metal-limited conditions. ModMeR target high quota or redundant metalloproteins and, by adjusting their synthe…
“I do those things to pass the time.”: Active ageing during fourth age
2021
Active ageing is a dominant but disputed discourse in the field of ageing. Since it is usually associated with the third age, this article will focus on the active ageing of older adults who need care and services, who are known as the fourth agers. Our data consists of interviews collected from 16 older adults. We analysed the data through content analysis that was guided by the Active Ageing Index (AAI) that is a measuring tool concerning active ageing. According to our results, active ageing during the fourth age can be understood through the lens of small actions and precarity. Although some actions had to be given up or modified, participants were active in various ways, and help from …

Dinosaur bonebed amber from an original swamp forest soil
2021
AbstractDinosaur bonebeds with amber content, yet scarce, offer a superior wealth and quality of data on ancient terrestrial ecosystems. However, the preserved palaeodiversity and/or taphonomic characteristics of these exceptional localities had hitherto limited their palaeobiological potential. Here we describe the amber from the Lower Cretaceous dinosaur bonebed of Ariño (Teruel, Spain) using a multidisciplinary approach. Amber is found in both a root layer with amber strictly in situ and a litter layer namely composed of aerial pieces unusually rich in bioinclusions, encompassing 11 insect orders, arachnids, and a few plant and vertebrate remains, including a feather. Additional palaeont…
El uso del dispositivo en el estudio de los discursos gerenciales
2021
Resumen: En el marco del estudio de los discursos gerenciales, se destacan en el presente texto algunas de las aportaciones de Medina-Vicent (2020), especialmente el análisis de los procesos de individualización y despolitización de mensajes que entroncarían con las reivindicaciones del feminismo. En este contexto, se propone la incorporación del concepto foucaultiano de dispositivo para el estudio de los elementos que contribuyen a la difusión de los discursos gerenciales. Este concepto podría ser de utilidad en la investigación empírica, proporcionando una herramienta conceptual para estudiar como un sistema homogéneo de relaciones de saber y poder los distintos elementos que conformarían…
Family Council From A Cultural Approach: the case of eastern european countries
2021
The family council is a formal mechanism of the family governance in family businesses that aims to give a voice to all members of the family, and to unify the interests of all members. These interests are identified with the purpose of the family, necessary to achieve a long-term legacy, and the sustainability of the company. However, the establishment of the family council is a topic that is still at an incipient stage, both in the literature and for practitioners, so our contribution advances the understanding of family governance within the sphere of family businesses culture and context. For that purpose, we rely on two cultural indexes widely accepted in the literature. We have taken …

2021
The family Belpaoviridae comprises metazoan-infecting reverse-transcribing viruses with long terminal repeats, commonly known as Bel/Pao LTR retrotransposons. These viruses share evolutionary history and genes involved in genome replication and virion formation with reverse-transcribing viruses of the families Metaviridae, Pseudoviridae, Retroviridae and Caulimoviridae. These five families form the order Ortervirales. This is a summary of the ICTV Report on the family Belpaoviridae, which is available at ictv.global/report/belpaoviridae.
El uso expresivo de las palabras: Daño sexual, narración y transformación
2021
Resumen: Marta Suria escribe Ella soy yo como parte de su respuesta a la irrupción del recuerdo de las agresiones sexuales que había sufrido desde su infancia. Confía en que la forma en que narra su experiencia, la transforme y la libere. ¿Cómo es posible, sin embargo, que una forma de narrar nos transforme, tenga el poder de liberarnos? En este escrito, describiremos, primero, la concepción de la relación entre lenguaje y experiencia que da pie a esta perplejidad; esbozaremos, posteriormente, una concepción alternativa en la que esa perplejidad se disuelve y desde la que es fácil reconocer el poder transformador de ciertas formas de narrarnos. Descansará esta concepción alternativa en la i…
Improved pairwise comparison transitivity using strategically selected reduced information
2021
To judge the mutual relationship among elements, pairwise comparisons (PC) are widely used in decision modelling. PC is especially useful when the involved elements are intangible. Frequently, the number of elements to be compared may be very large. When dealing with n elements, the number of PCs is, under the reciprocity hypothesis, n(n − 1)/2. PCs are compiled in so-called pairwise comparison matrices (PCM). In the presence of missing entries due to uncertainty or lack of information, decision-making must be performed from the available incomplete information. Making all the comparisons in the complete case may be tedious, strenuous and time-consuming for the actors, may blur the body of …
Citizen experts in participatory governance: Democratic and epistemic assets of service user involvement, local knowledge and citizen science
2021
Initiatives that attribute expert status to ‘ordinary citizens’ proliferate in a range of societal realms and are generally celebrated for ‘democratising expertise’. By tapping new sources of knowledge and participation simultaneously, such ‘citizen expertise’ practices seem to provide responses to the contemporary decline of trust in political elites and traditional experts that seriously challenges the legitimacy of democratic policy-making. This study distinguishes between three quintessential types of citizen expertise (‘local knowledge’, ‘service user involvement’ and ‘citizen science’) and, from an integrated perspective, critically discusses the value of citizen expertise for public…

On the Mechanistic Origins of the pH-Dependency in Au-Catalyzed Glycerol Electro-Oxidation: Insight from First Principles Calculations
2021
Electrocatalytic oxidation of glycerol (EOG) is an attractive approach to convert surplus glycerol to value-added products. Experiments have shown that EOG activity and selectivity depend on the electrocatalyst, but also on the electrode potential, the pH, and the electrolyte. For broadly employed gold (Au) electrocatalysts, experiments have demonstrated high EOG activity under alkaline conditions with glyceric acid as a primary product, whereas under acidic and neutral conditions Au is almost inactive producing only small amounts of dihydroxyacetone. In the present computational work, we have performed an extensive mechanistic study to understand the pH- and potential- dependency of Au-cat…

The BioS4You project engages young learners in STEM subjects, starting with current issues of interest for them, as the social and environmental impact of new technologies, connecting STEM conce…
Contingency plan selection under interdependent risks
2021
Managing supply chain risks (SCRs) has become an increasingly strategic key factor over the last decade, aimed at pursuing and maintaining business success. These types of risks clearly pose an important challenge to managers nowadays, and evaluating uncertainty affecting business scenarios is crucial. Indeed, COVID-19 has been dangerously affecting supply chains of global manufacturers, and is indicated as a main trigger cause of supply chain disruptions for a huge number of enterprises. Major effects derived from epidemic outbreaks on supply chains should be further adequately investigated since enterprises have been adopting poor risk management plans [1] to face them. Many companies, fo…

Student teachers and their attitudes towards ICT: Lessons learned from three different countries
2021
This paper explores the attitudes that student teachers in Malta, Norway, and Spain convey to digital technologies in formal educational settings as they start the 1st semester. A number of studies look at educational inclinations and employment of digital technologies (Granić & Marangunić, 2019; Ritter, 2017; Scherer & Teo, 2019). We have chosen to examine student teachers’ attitudes towards the professional use of digital technologies within a pedagogical framework. In this respect, a comparative qualitative analysis of one open-ended question that forms part of a more extensive questionnaire distributed to all participants is considered. The employed analytical lens subsequently …

Abstract. Stratospheric inorganic chlorine (Cly) is predominantly released from long-lived chlorinated source gases and, to a small extent, very short-lived chlorinated substances. Cly includes the reservoir species (HCl and ClONO2) and active chlorine species (i.e., ClOx). The active chlorine species drive catalytic cycles that deplete ozone in the polar winter stratosphere. This work presents calculations of inorganic chlorine (Cly) derived from chlorinated source gas measurements on board the High Altitude and Long Range Research Aircraft (HALO) during the Southern Hemisphere Transport, Dynamic and Chemistry (SouthTRAC) campaign in austral late winter and early spring 2019. Results are c…

Background Physical activity alleviates chronic stress. The latest research suggests a relationship between resilience and physical fitness. Beneficial adaptations of the hypothalamic-pituitary-adrenal axis, sympathetic nervous system, endocannabinoid system, and tryptophan pathway, which are induced by an active lifestyle, are considered to be conducive to resilience. However, detailed knowledge on the molecular link between the effects of acute and chronic physical exercise and improved resilience to stress in humans is missing. Moreover, the relationship between innate and acquired aerobic capacity and resilience is poorly understood. Objective The aim of this study is to implement a hu…
Detection of collinear high energetic di-photon signatures with Micromegas Detectors
2021
The search for weakly interacting, light particles that couple to photons received significant attention in recent years. When those particles are produced at high energies, they lead to two, nearly collinear photons after their decay and hence can be detected by an electromagnetic calorimeter system. The typical dominant background in searches for those high energetic weakly particles are single, high energetic photons, which leave similar signatures in a standard calorimeter system. One promising approach to separate signal from background events is to employ a dedicated pre-shower detector in front of the calorimeter that can distinguish one- and two-photon signatures. In this work we pr…

2021
The aims of this study were to examine the relationship between anthropometric variables, physical performance, and functional test with serve velocity regarding tennis players’ level and to design regression models that effectively predict serve velocity. A sample of sixteen male tennis players participated in this study (national level = 8, professional level = 7). Anthropometric measurements (body mass, height, body mass index and body segments) and physical test (hand strength, countermovement jump, jump on serve, and serve velocity) and functional test (medicine ball throw overhead and shot put) were performed. No differences in anthropometrics and physical test were found between nati…
In situ monitoring of moisture uptake of flax fiber reinforced composites under humid/dry conditions

The use of green materials such as natural fiber-reinforced composites represents an increasingly stringent prerogative in the future planning of industrial and non-industrial production. The optimization of these materials is the main aim of the current research, focused on the evaluation of the behavior of flax fiber reinforced composites exposed to isothermal adsorption and desorption cycles, at varying the partial pressure of water vapor (P/P0). For this purpose, the moisture uptake and the morphology changes of the composite material and their constituents were in situ monitored through a measurement protocol, by using a dynamic vapor sorption (DVS) analysis, coupled with an environmen…
Common determinants of dental caries and obesity in children: A multi-ethnic nested birth cohort study in the United Kingdom
2021
The article examines the common determinants of childhood dental caries and obesity. Longitudinal data from the Born in Bradford cohort study (BiB1000) (n = 1735) and dental data (dental general anaesthetics (GA) and oral health survey 2014/15) (n = 171) were used to test a framework on the social determinants of childhood dental caries (decayed, missing, filled teeth (dmft) index) and obesity (body mass index (BMI)). The BiB1000 data were collected at pregnancy week 26–28 and after birth at 6, 12, 18, 24 and 36 months. The determinants were demographics, wellbeing, socio-economic status (SES), dietary behaviours and physical activity behaviour of the children. Missing data were accounted f…
Are Cover Crops Affecting the Quality and Sustainability of Fruit Production?
2021
The study of the interaction between fruit trees and cover crops has been addressed in numerous works over the last 50 years or more, evidencing the need to evolve from a productive orchard to an orchard that plays different ecosystem roles in terms of environmental sustainability rather than just productivity. This review, through an analysis of the scientific literature since the 1950s, highlights the development of sustainable soil management models in fruit tree orchards, mostly considering the relationship with fruit quality traits and with the ecosystem services that result from the adoption of cover crops, aiming at identifying and formulating technical recommendations in perennial o…

Effect of a new amido‐imidazolium compound as a clay modifier on properties of polypropylene composites
2021
Halloysite nanotubes (HNT) and montmorillonite (Mt) were modified by a novel, dicarboxylic fatty acid substituted amido-imidazolium chloride. It was found that the modification process of the clays by the imidazolium compound improved their dispersion in the polymer matrix, while HNT were a more beneficial filler of PP than Mt. PP/imidazolium modified HNT composites (PP/HNT-M) showed significant increase in thermo-oxidative stability, flexibility, and toughness, combined with a slight reduction in stiffness, as well as a lack of changes in crystallinity and strength, compared with neat PP. These effects were not observed for PP/Mt composites. The formation of strong interactions between the…

Graves' Autoantibodies Exhibit Different Stimulating Activities in Cultures of Thyrocytes and Orbital Fibroblasts Not Reflected by Clinical Assays
2021
Background: The pathogenesis of Graves' hyperthyroidism (GH) and associated Graves' orbitopathy (GO) appears to involve stimulatory autoantibodies (thyrotropin receptor [TSHR]-stimulating antibodies [TSAbs]) that bind to and activate TSHRs on thyrocytes and orbital fibroblasts. In general, measurement of circulating TSHR antibodies by clinical assays correlates with the status of GH and GO. However, most clinical measurements of TSHR antibodies use competitive binding assays that do not distinguish between TSAbs and antibodies that bind to but do not activate TSHRs. Moreover, clinical assays for TSAbs measure stimulation of only one signaling pathway, the cyclic adenosine monophosphate (cAM…
Gender Gaps in Wages and Mortality Rates During Industrialization: The Case of Alcoy, Spain, 1860–1914
2021
What role did women play during industrialization? Interpretations of this key period of our history have been largely based on analyses of male work. In this paper, we offer evidence of the effects of women's involvement in the industrialization process that took place in Alcoy, Spain, over the period 1860-1914. Using data drawn from historical sources, we analyse labour-force participation rates and wage series for women and men in the textile industry and three other sectors of activity (education, health and low-skill services). We then connect the gender pay gaps with life expectancy indicators. Our results suggest that women's contribution to household income might have favoured the f…
