Authors: Echeverría Samanes Benito , Martínez Clares Pilar 
Published: May 2021

La investigación es un motor de desarrollo y equidad que permite encontrarnuevas respuestas a los principales desafíos de la sociedad, contando con laparticipación de quienes conocen en profundidad el tema objeto de estudio. Trasdiagnosticar la deficitaria situación de la Investigación sobre Formación Profesional en España (IFPE), un comité de expertos internacionales analiza los 12 retos a los que se enfrenta, según las conclusiones de un grupo de investigadores nacionales expertos en el tema, refrendadas por otro grupo de agentes clave implicados en el desarrollo de la FP en nuestro país. A juicio del comité internacional, los resultados revelan que en sus países no es tan necesario como en España un marco de referencia común con fundamentos teóricos y delimitaciones conceptuales, ni una clasificación normalizada de investigación. Sí que consideran un tanto necesaria una agenda, un plan estratégico de investigación y determinadas líneas temáticas de investigación, aunque menos centros dedicados a analizarlas. Estiman muy necesaria la existencia de redes estatales de investigadores de FP, recursos y financiación, integración de los actores implicados, facilidad de acceso a microdatos y bases de datos, así como promover cauces de comunicación con la administraciónautonómica, estatal y europea, para facilitar y propulsar la investigación e innovación de la FP. Concluye reseñando que España precisa la configuración progresiva e inclusiva de un ecosistema de la IFPE, contando con la participación activa de agentes gubernamentales, académicos, económicos y sociales, comprometidos en su desarrollo, a la que es de esperar que se incorporen cuantos actores estén interesados en potenciar la FP mediante la investigación e innovación.
A Novel Data-Driven Subsea Project Delivery Ecosystem
Authors: Noiray Gautier , Boisne Matt 
Published: May 2021

Beyond the craze for Digitization in the industry, there remains a lack of clarity on the concrete changes and value most companies are extracting from it. The recent market conditions, exacerbated by the current global pandemic, make this question more relevant than ever, as any new investment becomes ever more challenged.
McDermott have been at the forefront of the energy industry digitization, and over the past couple of years, they have ideated, developed, and implemented a novel data-driven Subsea Project delivery ecosystem. This cross-functional ecosystem leverages cloud technology and Python scripting to enhance and systemize processes, fundamentally tying back to the field architecture digital twin. The purpose of the paper is to communicate the main drivers at the origin of the initiative, to describe the current solution, including the associated risks (and mitigations) and the benefits that arise from its use as well as give the reader a sense of the more long-term vision.

ENGLISH ABSTRACT: During the first COVID-19 lockdown, public health officials and political decision makers were aware that the lockdown would have some sort of psychological repercussion, but it was totally unknown what reactions the disease would evoke. This article investigates how the physical and mental health (well-being) were affected. Data from the COVID-19 survey indicate that negative consequences were uneven distributed in the population with especially young women, but also young men reporting alarming degrees of low well-being.
DANSK RESUMÉ: Gennem første COVID-19 nedlukning i foråret 2020 var det endnu helt ukendt, hvilke reaktioner sygdommen ville fremkalde. Denne artikel undersøger, hvordan det fysiske og psykiske helbred (trivslen) blev påvirket. Den fremhæver, hvordan især de negative påvirkninger ramte befolkningen skævt, og at særligt de unge kvinder, men også unge mænd rapporterede mistrivsel i alarmerende omfang.

Published: May 2021

Aim: To investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium.
Study Design: The experiment was laid out in Randomized Block Design with three replications.
Place and Duration of Study: Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry.
Methodology: The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2).
Results: The results of field experiment revealed that the N availability in soil was more at all stages of crop growth by two and three split doses of potassium. The KClO3 increased the available N status at active and panicle initiation stages. Whereas in flowering stage, the KCl recorded the higher available N status in soil. The nitrogen uptake at active tillering stage and flowering stage was evidently improved with three split doses of potassium. Whereas in panicle initiation stage, the two split doses registered higher N uptake. The nitrogen uptake by both grain and straw was conspicuously higher in three and two split doses of potassium.
Conclusion: The split applications tested in this investigation influenced the available N status in soil. Almost in all the stages, three split applications retained more available N in soil. This implies the positive interaction of potassium with nitrogen.

Published: May 2021

Improper postharvest management of red chili pepper results in the invasion of Aspergillus spp. It is the most common pathogen that infects chili resulting in the production of aflatoxin - the most potent biological toxin. The present study was aimed to study the occurrence of naturally occurring fungal pathogens in the commercially available chilli pepper in India. About twenty samples were collected from retail stores and commercial markers of Tamil Nadu, India. Isolation and purification of the naturally occurring fungal pathogens were carried out using a potato dextrose agar medium. Results showed that the samples were contaminated with Aspergillus flavus, A. parasiticus, and A. niger. Scanning electron microscopy (SEM) was done to morphologically confirm the pathogens. SEM analysis also showed the internal structural damage caused by the pathogens. Followed by the isolation, all the samples that contained A. flavus were tested for aflatoxin production using the thin layer chromatography (TLC) method. It was found that a total of 16 chilli samples were tested positive for aflatoxin production. It could be seen that the tropical climatic conditions of India increased the probability of aflatoxin production in the chilli pepper.

Published: May 2021

Aims: The main objective of the study was to explore the influences of socio-demographic factors of lemon cultivators on accepting pest management practices.
Study Design: A total of 120 lemon growers of the Tangail district were selected as samples following the proportionate random sampling technique. Primary data were collected from sampled respondents using a pre-designed and pre-tested questionnaire by face-to-face interview.
Results and Discussion: Findings indicate that majority of the respondents were middle-aged (69.2%), having a secondary level of education (47.5%), small farm size (73.3%), medium family size (57.5%), and medium use of information sources (74.2%). Farmers use chemical, mechanical, and cultural pest management practices, with the majority of respondents had a moderate degree of adoption. Education, annual family income, contact with the source of information, and organizational participation of the respondents showed positive significant relationships with their adoption of pest management practices. High input price, low market price of the product, disease, and pest attack was identified as the major problems faced by the lemon growers.
Conclusion: Adoption of pest management practices significantly influenced by socio-economic factors of lemon growers. Hence, agricultural extension agents should step forward to work with different groups of farmers for raising their knowledge of integrated pest control and improve expertise in lemon cultivation. Furthermore, the government should take the requisite steps to address issues such as high production costs, low commodity prices, and disease and pest infestation.

Published: May 2021

AbstractThe development of highly efficient electrocatalysts toward the oxygen evolution reaction is imperative for advancing water splitting technology to generate clean hydrogen energy. Herein, a two dimensional (2D) nanosheet ammonium cobalt phosphate hydrate (NH4CoPO4·H2O) catalyst based on the earth‐abundant non‐noble metal is reported. When used for the challenging alkaline saline water electrolysis, the NH4CoPO4·H2O catalyst with the optimal thickness of 30 nm achieves current densities of 10 and 100 mA cm−2 at the record low overpotentials of 252 and 268 mV, respectively, while maintaining remarkable stability during the alkaline saline water oxidation at room temperature. X‐ray absorption fine spectra reveal that the activation of Co (II) ions (in NH4CoPO4·H2O) to Co (III) species constructs the electrocatalytic active sites. The 2D nanosheet morphology of NH4CoPO4·H2O provides a larger active surface area and more surface‐exposed active sites, which enable the nanosheet catalyst to facilitate the alkaline freshwater and simulated seawater oxidation with excellent activity. The facile and environmentally‐benign H2O‐mediated synthesis route under mild condition makes NH4CoPO4·H2O catalyst highly feasible for practical manufacturing. In comparison with noble metals, this novel electrocatalyst offers a cost‐effective alternative for economic saline water oxidation to advance water electrolysis technology.
Polyoxometalate‐Single Atom Catalysts (POM‐SACs) in Energy Research and Catalysis
Authors: Liu Rongji , Streb Carsten 
Published: May 2021

AbstractSingle atom catalysts—SACs—have received intense interest in sustainable energy research due to their enormous application potential and broad catalytic scope. In particular, SACs anchored on molecular metal oxides—polyoxometalates (POMs)—offer unrivalled possibilities as models to understand the function of these complex systems on the atomic level. Research questions which are difficult to address for classical heterogeneous SACs can be addressed by experiment and theory using POM‐SACs as prototype catalysts. This review reviews the emerging field of POM‐SAC research with a focus on fundamental properties and their application in energy conversion and storage technologies including water splitting, CO/CO2‐ as well as N2‐activation. Current limitations of the field are identified and possible routes to overcome these are described. Future areas of development, including polyoxometalate‐single‐site catalysts, are highlighted, and critically assessed to enable the community to develop this fast‐moving field further.
The influence of Russia's 2010/2011 wheat export ban on spatial market integration and transaction costs of grain markets
Authors: Svanidze Miranda , Götz Linde , Serebrennikov Dmytro 
Published: May 2021

AbstractStrong harvest shortfall and high world market prices prompted the Russian government to implement a wheat export ban in 2010 aiming to dampen domestic wheat prices. Building on regional price and trade data of Russia's wheat producing regions, we find strengthened domestic wheat market integration during the export ban period. Market integration decreased to its pre‐ban level in the post‐ban period; however, higher transaction costs resulting from increased risk of domestic grain trade during the export ban continued to prevail. Although market integration was temporarily strengthened, the export ban generally hampers market development in the long run.

Published: May 2021

AbstractAlthough lipid nanodiscs are increasingly used in the structural studies of membrane proteins, drug delivery and other applications, the interaction between the nanodisc belt and the protein to be reconstituted is a major limitation. To overcome this limitation and to further broaden the scope of nanodiscs, a family of non‐ionic amphiphilic polymers synthesized by hydrophobic functionalization of fructo‐oligosaccharides/inulin is reported. We show the stability of lipid nanodiscs formed by these polymers against pH and divalent metal ions, and their magnetic‐alignment properties. The reported results also demonstrate that the non‐ionic polymers extract membrane proteins with unprecedented efficiency.

AbstractSinglet diradicaloids hold great potential as semiconductors for organic field‐effect transistors (OFETs). However, their relative low material and device stabilities impede the practical applications. Here, to achieve balanced stability and performance, two isomeric dibenzoheptazethrene derivatives with singlet diradical character were synthesized in a concise manner. Benefitting from the aromatic stabilization, both compounds display a small diradical character and large singlet–triplet gap, as corroborated by variable‐temperature electron paramagnetic resonance spectra, single‐crystal analysis, and theoretical calculations. OFET devices based on single crystals showed a high hole mobility of 0.15 cm2 V−1 s−1, which is the highest for zethrene‐based semiconductors. Both isomers exhibited remarkable material stability in air‐saturated solutions as well as excellent bias‐stress and storage stability in device under ambient air.
