Maize landraces management to avoid transgenic contamination, decreases yield and seed quality

ABSTRACT Producing high-quality seeds for agroecological agriculture is needed because the plants will be exposed to a diversity of environments and management practices. Sowing times and population densities can influence the quality of seeds produced by landraces. Further, seeds for agroecological cultivation must not be contaminated by transgenes. In this context, it is necessary to know the agronomic performance of landraces outside of the recommended growing period to avoid gene flow with transgenic cultivars. Thus, the objective of this work was to determine the germination rate, vigor and sanitary quality of seeds of maize genotypes cultivated in an agroecological system at different sowing times and densities. A split-split-plot design was used in the 2016/2017 and 2017/2018 growing seasons. The physiological quality evaluation was based on germination and vigor tests, and the sanitary quality was obtained by visually examining the seeds. The results showed a significant simple effect of genotype, sowing time and density, as well as double and triple interactions among factors for all evaluated traits. The most suitable time for sowing the corn landraces evaluated in an agroecological system in western Santa Catarina is September, when the seeds exhibited the highest percentage of germination and vigor and there was a lower incidence of pathogens. At this time, a density of 55,000 plants·ha–1 had the best result for germination. Late sowing was tested to avoid gene flow from transgenic varieties that usually are sown in September, but the results indicated penalties, such as a decrease in seed yield and quality.
Critical Review—Experimental Diagnostics and Material Characterization Techniques Used on Redox Flow Batteries

Grid-scale energy storage systems are of interest as the world increases reliance on renewable energy sources. Redox flow batteries are a type of grid-scale energy storage technology that shows exceptional promise for accommodating the dynamic output of wind and solar power sources. The research community employs dozens of diagnostic techniques to investigate nearly all facets of these devices. Material properties, operational losses, transport, and integrated system properties are studied through the lens of electrochemical, physical, and chemical phenomena that ultimately dictate cost by influencing efficiency, durability, power, and capacity. These diagnostic techniques can, if applied correctly, elucidate not only the types of losses in redox flow batteries, but also tie those losses to fundamental driving forces in such systems so that next generation systems and models can be designed. This review details various diagnostic techniques used in flow battery analysis. The benefits, unique insights, and limitations of these techniques are discussed. Recommendations are also made to assist researchers in identifying the diagnostics that can advance their particular investigations. The review concludes with a summary of opportunities for new diagnostics that are needed to enable solution of persistent issues in redox flow battery research and development. © The Author(s) 2018.

Cadre d’analyse des facteurs qui caractérisent une perception positive de l’activité physique chez les élèves du primaire

Les interventions en milieu scolaire doivent favoriser le developpement d’une perception positive (PP) de l’activite physique (AP) chez les eleves pour avoir des repercussions a long terme sur leur mode de vie actif. Toutefois, les perceptions des eleves en lien avec l’AP sont sous-representees dans la litterature scientifique et plus particulierement lors du deploiement des interventions en milieu scolaire primaire. Cet article a donc pour but de presenter : (1) les facteurs qui caracterisent une PP de la pratique d’AP chez les eleves du milieu scolaire primaire et (2) de modeliser un cadre d’analyse permettant de categoriser ces facteurs. Une recherche documentaire a ete menee afin d’identifier les facteurs qui caracterisent une PP de l’AP chez les eleves du primaire en plus d’elaborer un cadre d’analyse. Les resultats mettent en evidence 24 facteurs caracterisant une PP de l’AP chez les eleves du primaire. Ces facteurs sont presentes dans un cadre d’analyse elabore a partir du modele socio-ecologique de McLeroy et al. (1988). Ce cadre d’analyse est pertinent pour identifier, decrire et caracteriser les perceptions des eleves dans le contexte ou des strategies d’intervention visant a augmenter leur niveau d’AP sont mises en place en milieu scolaire.
A Comprehensive Review on Residential Demand Side Management Strategies in Smart Grid Environment

The ever increasing demand for electricity and the rapid increase in the number of automatic electrical appliances have posed a critical energy management challenge for both utilities and consumers. Substantial work has been reported on the Home Energy Management System (HEMS) but to the best of our knowledge, there is no single review highlighting all recent and past developments on Demand Side Management (DSM) and HEMS altogether. The purpose of each study is to raise user comfort, load scheduling, energy minimization, or economic dispatch problem. Researchers have proposed different soft computing and optimization techniques to address the challenge, but still it seems to be a pressing issue. This paper presents a comprehensive review of research on DSM strategies to identify the challenging perspectives for future study. We have described DSM strategies, their deployment and communication technologies. The application of soft computing techniques such as Fuzzy Logic (FL), Artificial Neural Network (ANN), and Evolutionary Computation (EC) is discussed to deal with energy consumption minimization and scheduling problems. Different optimization-based DSM approaches are also reviewed. We have also reviewed the practical aspects of DSM implementation for smart energy management.

Self-assembly of polymer-like structures of magnetic colloids: Langevin dynamics study of basic topologies

Abstract We study the self-assembly of colloidal magnetic particles permanently cross-linked into polymer-like structures with different topologies, that we call supracolloidal magnetic polymers (SMPs). In order to understand the influence of the interparticle permanent links, we investigate SMPs holding the main topologies observed in the self-assembly of non-cross-linked magnetic particles via grand canonical Monte Carlo simulations: chains, rings and simple branched structures. Here, using molecular dynamics simulations, we focus on systems of SMP pairs. Our results evidence that the presence of crosslinkers leads to the formation of new types of aggregates, not previously observed for individual magnetic colloids.
Universal Design for Learning in Adapted National-level Digital Mathematics Textbooks for Elementary School Students with Disabilities

ABSTRACT Learning mathematics in an inclusive classroom is challenging for many students with disabilities. The adapted digital mathematics textbooks for Grades 3 to 6 in South Korea were designed to support these students’ access to the general mathematics curriculum. This study evaluates these textbooks according to the Universal Design for Learning (UDL) guidelines. The design features of the mathematics textbooks varied within and across various UDL checkpoints. Overall, the aspect of providing multiple means of action and expression was the most frequently observed, followed by providing multiple means of representation and providing multiple means of engagement. Special education teachers and textbook developers can use these results as a resource for designing curricula and lessons for students with disabilities in the inclusive classroom.
Trends and Future Prospects in MOOC Researches: A Systematic Literature Review 2013–2020

Advent of internet has a revolutionary impact on every sector of economy and so is with the education sector, which has witnessed the evolution of online education through scalable educational technology, namely, Massive Open Online Courses (MOOCs). The purpose of this paper is to summarize the pool of available knowledge related to MOOCs in the scholarly literature, published during the period 2013–2020. One hundred and two available published studies in peer reviewed journals & conferences searched in major academic databases have been reviewed and presented in the systematic literature review. The findings have been divided under the various research themes of MOOCs including geographical contribution of MOOC studies, citation trends, prominent research themes, theoretical frameworks and methodological rigor in the existing scholarly works. The results demonstrate that most empirical research were conducted by the researchers having affiliation to institutions based out of United States followed by institutions in the developing economies of China and India. The most focused area of research in MOOCs is on MOOC adoption. Limited research has happened on poor MOOC completion status, the instructor-related topics and on democratization of MOOC. Thrust areas of MOOC researches and future research directions are also discussed.
Probing the Southern Cascadia Plate Interface With the Dense Amphibious Cascadia Initiative Seismic Array

Fault coupling is vital in determining the amount of strain that is accumulated along faults. The magnitude and location of stored elastic strain energy in highly coupled regions has important implications for understanding the full range of slip behavior at plate boundary faults, as well as earthquake and tsunami hazards. We use the temporary dense amphibious array of seismometers offered by the Cascadia Initiative to create a high‐resolution catalog of events to examine the spatio‐temporal behavior of earthquakes near the plate interface. The data show that in southern Cascadia the plate interface updip of the geodetically locked region is nearly devoid of seismicity, therefore likely highly coupled and accumulating strain. The catalog reveals events that are clustered at the downdip edge of the highly coupled megathrust that correlate in time with nearby strain transient observations. Template matching of events in the cluster using permanent stations of the Northern California Seismic Network over a 10‐year period between 2010 and 2020 indicates that this cluster is unique in space and time. Its activity only during the strain transient provides support for the utility of seismic observations in the identification of strain transients.
In-plane orientation and composition dependences of crystal structure and electrical properties of {100}-oriented Pb(Zr,Ti)O3 films grown on (100) Si substrates by metal organic chemical vapor deposition

In-plane orientation-controlled Pb(Zrx,Ti1−x)O3 (PZT) films with a thickness of approximately 2 µm and a Zr/(Zr + Ti) ratio of 0.39–0.65 were grown on (100) Si substrates by pulsed metal–organic chemical vapor deposition (MOCVD). In-plane-oriented epitaxial PZT films and in-plane random fiber-textured PZT films with {100} out-of-plane orientation were grown on (100)c SrRuO3//(100)c LaNiO3//(100) CeO2//(100) YSZ//(100) Si and (100)c SrRuO3/(100)c LaNiO3/(111) Pt/TiO2/SiO2/(100) Si substrates, respectively. The effects of Zr/(Zr + Ti) ratio and in-plane orientation on the crystal structure, dielectric, ferroelectric, and piezoelectric properties of the films were systematically investigated. The X-ray diffraction measurement showed that the epitaxial PZT films had a higher volume fraction of (100) orientation than the fiber-textured PZT films in the tetragonal Zr/(Zr + Ti) ratio region. A large difference was not detected between the epitaxial films and the fiber-textured films for Zr/(Zr + Ti) ratio dependence of the dielectric constant, and remanent polarization. However, in the rhombohedral phase region [Zr/(Zr + Ti) = 0.65], coercive field was found to be 1.5-fold different between the epitaxial and fiber-textured PZT films. The maximum field-induced strains measured at 0–100 kV/cm by scanning atomic force microscopy were obtained at approximately Zr/(Zr + Ti) = 0.50 and were about 0.5 and 0.3% for the epitaxial and fiber-textured PZT films, respectively.
Visual References in the Description of Print Advertisements. A Four-Country Cross-Cultural Analysis

Abstract This paper investigates cross-cultural differences in the usage, themes, and factors of visual-related references in describing print advertisements. American, Russian, Japanese, and Polish respondents participated in an open-ended survey about three translated ads adapted into the existing visual. Respondents used less visual than non-visual descriptions, and their frequency differed by the ad. Similarities and differences were influenced by the specific advertisement, not by respondents' country. Advertisements require individual assessment for visual adaptation strategy. This pilot study introduces the concept of visual and non-visual descriptions of advertising, visual references themes and variable of advertising case to assess differences between countries.
Analysis on ASEAN and European Union Policies Regarding Covid-19

COVID-19 has impacted multiple sectors of life. Experts believe that regional cooperation is a key effort that should be done to deal the COVID-19 pandemic. Regional cooperation starts with common interests among parties and provides benefits for every country involved in it. This article provides an overview of the socio-economic impact of COVID-19 as well as a comparison of the forms of regional cooperation carried out by Association of Southeast Asian Nations (ASEAN) and the European Union (EU) in responding COVID-19. This study uses literature studies in data collection. From the results of several studies that have been carried out before, both regions chose to conduct cooperation in the health and economic fields to respond to COVID-19. ASEAN's response in responding to the pandemic can be seen stronger in the principles of partnership that have been established with several partner countries. In addition, the principle of solidarity, exchange of information, knowledge, as well as strengthening institutional cooperation in ASEAN itself is an important point in the regional cooperation carried out. On the other hand, in addition to cooperation in the health sector, EU focuses on financial instruments among its collaborative approaches in the availability of aid packages to banking actors and institutions. The package of assistance provided by the EU to avoid market distortions and revive economic sectors is provided through the provision of credit and liquidity.
Virtual Inertia Estimation Method of DFIG-based Wind Farm with Additional Frequency Control

With the increasing penetration of wind power, wind turbines participating in frequency regulation in support of the power system has become a clear consensus. To accurately quantify the inertia provided by the doubly-fed induction generator (DFIG) based wind farm, the frequency response model of DFIG with additional frequency control is established, and then by using Routh approximation, the explicit expression of the virtual moment of inertia is derived for the DFIG grid-connected system. To further enhance the availability of the expression, a matrix pencil-and least-square-based method for estimating the virtual moment of inertia provided by the wind farm is proposed. Finally, the numerical results tested by a DFIG grid-connected system and a modified IEEE 30-bus system verify the derived expression of the virtual moment of inertia and the proposed estimation method.
Characterization of terpene biosynthesis in Melaleuca quinquenervia and ecological consequences of terpene accumulation during myrtle rust infection

Abstract Plants use a wide array of secondary metabolites including terpenes as defense against herbivore and pathogen attack, which can be constitutively expressed or induced. Here, we investigated aspects of the chemical and molecular basis of resistance against the exotic rust fungus Austropuccinia psidii in Melaleuca quinquenervia, with a focus on terpenes. Foliar terpenes of resistant and susceptible plants were quantified, and we assessed whether chemotypic variation contributed to resistance to infection by A. psidii. We found that chemotypes did not contribute to the resistance and susceptibility of M. quinquenervia. However, in one of the chemotypes (Chemotype 2), susceptible plants showed higher concentrations of several terpenes including α‐pinene, limonene, 1,8‐cineole, and viridiflorol compared with resistant plants. Transcriptome profiling of these plants showed that several TPS genes were strongly induced in response to infection by A. psidii. Functional characterization of these TPS showed them to be mono‐ and sesquiterpene synthases producing compounds including 1,8‐cineole, β‐caryophyllene, viridiflorol and nerolidol. The expression of these TPS genes correlated with metabolite data in a susceptible plant. These results suggest the complexity of resistance mechanism regulated by M. quinquenervia and that modulation of terpenes may be one of the components that contribute to resistance against A. psidii.
A Cross-Sectional Examination of the Mental Wellbeing, Coping and Quality of Working Life in Health and Social Care Workers in the UK at Two Time Points of the COVID-19 Pandemic

As the COVID-19 pandemic continues to evolve around the world, it is important to examine its effect on societies and individuals, including health and social care (HSC) professionals. The aim of this study was to compare cross-sectional data collected from HSC staff in the UK at two time points during the COVID-19 pandemic: Phase 1 (May–July 2020) and Phase 2 (November 2020–January 2021). The HSC staff surveyed consisted of nurses, midwives, allied health professionals, social care workers and social workers from across the UK (England, Wales, Scotland, Northern Ireland). Multiple regressions were used to examine the effects of different coping strategies and demographic and work-related variables on participants’ wellbeing and quality of working life to see how and if the predictors changed over time. An additional multiple regression was used to directly examine the effects of time (Phase 1 vs. Phase 2) on the outcome variables. Findings suggested that both wellbeing and quality of working life deteriorated from Phase 1 to Phase 2. The results have the potential to inform interventions for HSC staff during future waves of the COVID-19 pandemic, other infectious outbreaks or even other circumstances putting long-term pressures on HSC systems.
Mechanical properties and bond strength of bimetallic AA1050/AA5083 laminates fabricated by warm-accumulative roll bonding

ABSTRACT Accumulative roll bonding (ARB) is one of the most promising methods for the industrial production of bimetal sheet materials. In this study, ARB process has been used to combine aluminium alloys 1050 and 5083 sheets to produce a bimetal AA1050/AA5083 composite laminate. Materials with 2, 4, 8, 16 and 32 layers were roll bonded as alternate layers at 300°C for 5 min before each cycle. In this study, the microstructure and mechanical properties of composite laminates have been studied versus number of layers by tensile and peel testing. Moreover, the fracture surfaces of samples after the tensile test have been studied during various number of composite layers by scanning electron microscopy (SEM). Results showed that the tensile strength and tensile toughness improved by the number of layers. Also, the peeling strength among the layers and elongation decreased in the samples with less than 8 layers and improved by increasing the number of composite layers considerably. Also, SEM results revealed that the depth of dimples in the fracture surface decreased by increasing the number of layers.
Institutional legitimacy and de-legitimacy: insights from the case of an innovative school

ABSTRACT The education field favors innovations, but innovative schools tend to fade after an initial ‘golden age. ’ According to the new institutional theory, this happens due to the innovative school’s need to achieve institutional legitimacy, which encounters several difficulties. This study aims to explore the journey to attaining legitimacy in one entrepreneurial school that gained legitimacy from some actors, but not from other relevant ones, and did not survive. Using a case study method, 30 interviews were conducted, and over 200 documents, including media articles, school protocols, and court protocols, were analyzed. The findings reveal that the concept of legitimacy is not dichotomous, but a continuum ranging from legitimacy to neutral and de-legitimacy, and stakeholders differ in their positions, resources, and type of legitimacy. Additional theoretical and practical implications are presented in the discussion.
