Infrastructure and Population of the OpenBiodiv Biodiversity Knowledge Graph
Authors: Dimitrova Mariya , Senderov Viktor , Georgiev Teodor , Zhelezov Georgi , Penev Lyubomir
Published: September 2021

OpenBiodiv is a biodiversity knowledge graph containing a synthetic linked open dataset, OpenBiodiv-LOD, which combines knowledge extracted from academic literature with the taxonomic backbone used by the Global Biodiversity Information Facility. The linked open data is modelled according to the OpenBiodiv-O ontology integrating semantic resource types from recognised biodiversity and publishing ontologies with OpenBiodiv-O resource types, introduced to capture the semantics of resources not modelled before.

We introduce the new release of the OpenBiodiv-LOD attained through information extraction and modelling of additional biodiversity entities. It was achieved by further developments to OpenBiodiv-O, the data storage infrastructure and the workflow and accompanying R software packages used for transformation of academic literature into Resource Description Framework (RDF). We discuss how to utilise the LOD in biodiversity informatics and give examples by providing solutions to several competency questions. We investigate performance issues that arise due to the large amount of inferred statements in the graph and conclude that OWL-full inference is impractical for the project and that unnecessary inference should be avoided.
A parasitic insect on a parasitic plant: a new species of the genus Formicoccus Takahashi (Hemiptera, Coccomorpha, Pseudococcidae) from Ishigaki Island, Japan
Authors: Tanaka Hirotaka , Suetsugu Kenji , Kamitani Satoshi
Published: September 2021

A new species of the genus Formicoccus Takahashi (Hemiptera, Coccomorpha, Pseudococcidae) collected from the holoparasitic plant Balanophora fungosa J. R. & G. Forst (Balanophoraceae), on Ishigaki Island, Japan, is described as Formicoccus yoshinoi Tanaka, sp. nov. based on the morphology of adult females. This species is similar to F. formicarius (1900) and F. erythrinae Williams, 2004, but differs from them by having fewer than six cerarii, and only one type of ventral oral collar tubular duct distributed on the medial area of the posterior abdominal segments. Keys to the Oriental species of the genus Formicoccus are provided.
Interprofessional Collaborative Practice and School Nursing: A Model for Improved Health Outcomes
Authors: Fleming Robin , Willgerodt Mayumi
Published: September 2021

Effective communication, teamwork, and interprofessional collaboration, or teams of health and non-health professionals working together, are critical to improving the patient experience of care; improving population health; and reducing healthcare costs (i.e., the Triple Aim). In 2016, the Interprofessional Education Collaborative (IPEC) Expert Panel updated its Core Competencies for Interprofessional Collaborative Practice. As health professionals who collaborate with an extensive network of health and non-health professionals, school nurses embody the aims of interprofessional collaboration (IPC). This article briefly reviews the background of interprofessional collaboration and describes ways that school nurse practice aligns with IPC core competencies to incorporate interprofessional collaboration. We discuss successes, such as case management and care coordination, and include challenges to IPC in the school setting. In conclusion, through case management and collaborative care, school nurse expertise in effective IPC fosters knowledge through which core competencies can be strengthened, with benefits for both patients and other healthcare providers.

Published: September 2021

We discuss periodic solution problems and asymptotic stability for inertial neural networks with $ D- $operator and variable parameters. Based on Mawhin's continuation theorem and Lyapunov functional method, some new sufficient conditions on the existence and asymptotic stability of periodic solutions are established. Finally, a numerical example verifies the effectiveness of the obtained results.

Published: September 2021

With the help of the conventional electrical method and the growing optogenetic technology, cardiac fibroblasts (Fbs) have been verified to couple electrically with working myocytes and bring electrophysiological remodeling changes in them. The intrinsic properties of cardiac functional autoregulation represented by excitation-contraction coupling (ECC) and mechano-electric feedback (MEF) have also been extensively studied. However, the roles of optogenetic stimulation on the characteristics of ECC and MEF in cardiomyocytes (CMs) coupled with Fbs have been barely investigated. In this study, we proposed a combined model composed of three modules to explore these influences. Simulation results showed that (1) during ECC, an increased light duration (LD) strengthened the inflow of ChR2 current and prolonged action potential duration (APD), and extended durations of twitch and internal sarcomere deformation through the decreased dissociation of calcium with troponin C (CaTnC) complexes and the prolonged duration of Xb attachment-detachment; (2) during MEF, an increased LD was followed by a longer muscle twitch and deformation, and led to APD prolongation through the inward ChR2 current and its inward rectification kinetics, which far outweighed the effects of the delaying dissociation of CaTnC complexes and the prolonged reverse mode of Na+-Ca2+ exchange on AP shortening; (3) due to the ChR2 current's rectification feature, enhancing the light irradiance (LI) brought slight variations in peak or valley values of electrophysiological and mechanical parameters while did not change durations of AP and twitch and muscle deformation in both ECC and MEF. In conclusion, the inward ChR2 current and its inward rectification feature were found to affect significantly the durations of AP and twitch in both ECC and MEF. The roles of optogenetic actuation on both ECC and MEF should be considered in future cardiac computational optogenetics at the tissue and organ scale.
Heat diffusion in a channel under white noise modeling of turbulence
Authors: Flandoli Franco ,   Scuola Normale Superiore, Piazza dei Cavalieri, 7, 56126 Pisa, Italy, Luongo Eliseo
Published: September 2021

A passive scalar equation for the heat diffusion and transport in an infinite channel is studied. The velocity field is white noise in time, modelling phenomenologically a turbulent fluid. Under the driving effect of a heat source, the phenomenon of eddy dissipation is investigated: the solution is close, in a weak sense, to the stationary deterministic solution of the heat equation with augmented diffusion coefficients.
Poincaré inequalities and Neumann problems for the variable exponent setting

Published: September 2021

In an earlier paper, Cruz-Uribe, Rodney and Rosta proved an equivalence between weighted Poincaré inequalities and the existence of weak solutions to a family of Neumann problems related to a degenerate $ p $-Laplacian. Here we prove a similar equivalence between Poincaré inequalities in variable exponent spaces and solutions to a degenerate $ {p(\cdot)} $-Laplacian, a non-linear elliptic equation with nonstandard growth conditions.
La valorisation des compétences de base sur le marché du travail français
Authors: Branche-Seigeot Aline
Published: September 2021

D’après la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d’années d’études. Mais à l’heure où l’éducation certifiée est discutée comme filtre, qu’en est-il de la valorisation des compétences, notamment de base, sur le marché du travail français ? Alors que de nombreuses recherches ont déjà été réalisées à ce sujet (dans les pays anglo-saxons principalement), aucune n’a encore été conduite sur cette thématique en France. Cette présente étude cherche alors à déterminer, via un modèle d’Heckman en deux étapes, dans quelle mesure l’accès à l’emploi et les salaires sont expliqués par le niveau en littératie, en numératie et en compréhension orale. Notre approche aura pour principal avantage de tenir compte d’un éventuel biais de sélection dans l’estimation des équations de gains, tout en appréhendant l’influence exercée par les compétences de base dans l’accès à l’emploi.
La question du retour d’expérience des stagiaires au sein des pratiques professionnelles de formateurs en insertion
Authors: Deicu Ioana
Published: September 2021

L’article rend compte des résultats d’une recherche réalisée de 2009 à 2010 dans la région Haute-Normandie, à propos des pratiques professionnelles d’un échantillon de formateurs responsables d’une action de formation-insertion. L’objet de cette recherche est de mieux comprendre quelle place occupe l’activité du stagiaire, notamment celle déployée en entreprise, dans les pratiques de formation. Après avoir précisé la problématique et la démarche méthodologique employée, nous allons montrer que même si les formateurs proposent à leurs stagiaires un temps et un espace de réflexion collective sur l’expérience vécue en entreprise, cette analyse demeure essentiellement centrée sur le prescrit.
L’internet : un nouvel outil pour de nouvelles pratiques de documentation pour la préparation de classe ?
Authors: Charpentier Philippe
Published: September 2021

Le manuel scolaire a été pendant longtemps le principal support utilisé par les maîtres de l’école primaire pour la préparation des leçons. Or, depuis peu, les maîtres disposent de l’internet qui permet d’avoir accès à de l’information, des documents pour leurs préparations. C’est à partir du cas de la géographie au cycle 3 de l’école primaire et d’une enquête par questionnaire auprès de cent treize enseignants que nous tentons de mesurer l’impact de l’internet sur la préparation des leçons. Il ressort de cette enquête que le manuel reste la source principale pour cette préparation, l’usage de l’internet ne venant qu’en complément de celui-ci. Les maîtres se sentent seuls face à la documentation qui leur est proposée, tant du fait d’un manque de formation initiale que continue.
Paysage scriptural adolescent, du papier au numérique
Authors: Schneider Elisabeth
Published: September 2021

La recherche, dont il est question ici, porte sur les pratiques d’écriture des adolescents, étudiées dans une double perspective : communicationnelle et géographique. L’écriture adolescente est interrogée en particulier sous l’angle de la production des espaces sociaux par l’écriture. Celle-ci, du papier au numérique, est approchée comme un outil permettant aux adolescents d’organiser leur expérience en élaborant un paysage scriptural complexe. C’est la démarche ethnographique mise en œuvre qui sera particulièrement l’objet d’analyse en tant que méthodologie et élaboration épistémologique.
Magmatisme et conditions de construction de textes de savoirs problématisés au collège
Authors: Chalak Hanaà
Published: September 2021

Les savoirs scolaires tels qu’ils sont présentés aux élèves semblent se limiter selon certaines recherches à des textes propositionnels dévoilant les résultats de la science sans aucune corrélation aux problèmes. Pour étudier les conditions de construction de textes de savoirs problématisés, nous avons mis en place, au sein d’une équipe de recherche, une séquence « forcée » en classe de quatrième traitant le problème du fonctionnement des volcans. Nous analysons les textes de savoirs produits par la classe lors de cette séquence afin de savoir s’ils portent les traces de la problématisation ou s’ils se contentent d’exposer uniquement les solutions. Cette analyse nous permettra d’effectuer une modélisation praxéologique des pratiques enseignantes de mise en texte et d’étudier les techniques mobilisées dans la séquence forcée. Il apparaît que la mise en texte problématisée nécessite l’introduction de sauts abstractifs permettant un travail d’abstraction et de généralisation du problème posé.
Apixaban and Eftrenonacog Alfa Treatment in a Patient with Moderate Hemophilia B and Cardiovascular Disease
Authors: Santoro Rita C. , Falbo Mariapia , Ferraro Alessandro
Published: September 2021

In developed countries, the life expectancy of patients with hemophilia (PwH) is now close to that of the unaffected male population. This means that these patients are at risk of developing age-related comorbidities, including cardiovascular disease. Managing cardiovascular disease in PwH patients can be particularly challenging, due to their high bleeding risk. To our knowledge, this is the first report of a male patient with moderate hemophilia B and hypertensive ischemic heart disease complicated by arrhythmia due to nonvalvular atrial fibrillation, who was treated with apixaban and left atrial appendage closure while receiving concomitant anti-hemorrhagic prophylaxis with eftrenonacog alfa.

Published: September 2021

Context: Tuberculosis (TB) is a common infectious disorder in developing countries. A significant load of patients with extrapulmonary TB are diagnosed in our institute, mostly involving the spine. Aim: We aimed to present our experience in the surgical management of spinal TB. Setting and Design: This was a retrospective observational study. Materials and Methods: Seventy patients (year 2016–2018) who underwent surgical management with minimum of 1-year follow-up (17 patients lost during follow-up) were graded as per the American Spinal Injury Association (ASIA) grading system for neurological deficits. All were surgically treated with laminectomy and epidural abscess drainage/transpedicular debridement of granulation with/without spinal stabilization. Thoracic and lumbar cases were managed by posterior approach; among them, 12 patients who had no significant cord compression and good ASIA grade with facet involvement (requiring fusion) underwent minimally invasive pedicle screw fixation. Cervical cases were managed mostly by anterior approach. All patients received Anti-tubercular treatment (ATT) post operatively as per protocol postoperatively, following which magnetic resonance imaging (MRI) spine was done. Statistical Analysis: Data were analyzed using SPSS software version 18.0 (SPSS Inc. Released in 2009. PASW Statistics for Windows, version 18.0. Chicago, IL, USA: SPSS Inc.). The continuous variables were analyzed using descriptive statistics using mean and standard deviation. Results: The average age was 42.5 years. The most common location was thoracic (28 patients), followed by lumbar (20 patients), cervical (16 patients), and thoracolumbar (6 patients). Twenty patients had epidural abscess with cord compression. All patients who presented within 4 weeks of onset of symptoms showed a statistically significant improvement postsurgery. Sixteen patients with epidural abscess had good neurological recovery immediately after surgery (ASIA B to ASIA D/E). Four patients with epidural abscess with late presentation remained ASIA A after surgery. All patients had good fusion rates (follow-up X-ray) at 1 year. After ATT course completion, all patients had complete eradication of disease (MRI spine). Conclusion: Surgical treatment for spinal TB, if performed early (within 4 weeks) with good decompression, results in satisfactory clinical outcome with early improvement in the neurological deficits. Posterior approach to the spine with decompression and fixation gives good results, and minimally invasive procedures further help lessen muscle dissection, less pain, and early mobilization.
Quantum evolution and sub-Laplacian operators on groups of Heisenberg type
Authors: Fermanian-Kammerer Clotilde , Fischer Véronique
Published: September 2021

In this paper we analyze the evolution of the time averaged energy densities associated with a family of solutions to a Schrödinger equation on a Lie group of Heisenberg type. We use a semi-classical approach adapted to the stratified structure of the group and describe the semi-classical measures (also called
quantum limits
) that are associated with this family. This allows us to prove an Egorov’s type Theorem describing the quantum evolution of a pseudodifferential semi-classical operator through the semi-group generated by a sub-Laplacian.
Spectral theory of the thermal Hamiltonian: 1D case
Authors: De Nittis Giuseppe , Lenz Vicente
Published: September 2021

In 1964 J. M. Luttinger introduced a model for the quantum thermal transport. In this paper we study the spectral theory of the Hamiltonian operator associated with Luttinger’s model, with a special focus at the one-dimensional case. It is shown that the (so called) thermal Hamiltonian has a one-parameter family of self-adjoint extensions and the spectrum, the time-propagator group and the Green function are explicitly computed. Moreover, the scattering by convolution-type potentials is analyzed. Finally, also the associated classical problem is completely solved, thus providing a comparison between classical and quantum behavior. This article aims to be a first contribution in the construction of a complete theory for the thermal Hamiltonian.
US employment inequality in the Great Recession and the COVID-19 pandemic*
Authors: Fazzari Steven M. , Needler Ella
Published: September 2021

This article compares inequality in employment across demographic groups in the Great Recession and the COVID-19 pandemic. We develop a measure to capture both how much employment declines during a recession and the persistence of employment losses. Results show a significant shift of job loss from men in the Great Recession to women in the COVID-19 lockdown. White workers fare better than other racial/ethnic groups in both recessions. Black and Hispanic women are hit especially hard in the COVID-19 pandemic. With our job-loss measure, less-educated workers had modestly worse outcomes in the Great Recession. However, during COVID-19, less-educated workers suffer much more severe employment consequences than more-educated groups. We discuss long-term effects of employment inequality and how these findings are relevant to debates about policy responses.

Published: September 2021

This study aims to propose an alternative hybrid approach to model renewable energy sources (RESs), which provide the most reliable results in comparison with the existing simulating tools. Within the framework of this approach, a specialized hybrid processor for modeling converter-interfaced generation (CIG) is developed. This study describes its structure and validation in the test system by comparing the results with commercial modeling tools, and also presents experimental studies of its operation as parts of the practical power system. The results obtained confirm the adequacy of the developed tools.

Published: September 2021

Meningkatnya kebutuhan akan jasa cetakan, dan bervariasinya mesin cetak yang ada meningkatkan jumlah dan macam variabel yang harus dimasukkan ke dalam perhitungan biaya cetak. Di samping itu fluktuasi harga-harga barang secara umum juga memiliki dampak secara langsung pada perhitungan ongkos biaya cetak. Dengan demikian dibutuhkan suatu aplikasi yang dapat membantu melakukan perhitungan ongkos biaya cetak yang praktis dan dapat dibawa kemana-mana. Peneliti membuat rancang bangun aplikasi kalkulasi biaya cetak buku yang dapat digunakan pada perangkat bergerak (mobile device) berbasis Android. Data variabel yang digunakan pada aplikasi tersebut disimpan di dalam aplikasi dan bersifat permanen. Hasil pengujian run-time yaitu saat membuka halaman Daftar Harga/Tarif, baik pada aplikasi Pemutakhiran Data Harga/Tarif maupun aplikasi Kalkulasi Biaya Cetak dibutuhkan waktu lebih kurang 5 detik untuk menampilkan semua nominal harga dan tarif secara keseluruhan. Hal ini terjadi karena data harga dan tarif disimpan pada online database sehingga dibutuhkan untuk proses komunikasi data pada jaringan internet. Sedangkan hasil pengujian perhitungan menunjukkan adanya perbedaan antara hasil perhitungan manual dan hasil perhitungan aplikasi dengan prosentase kesalahan 0,4%, dengan demikian tingkat akurasi perhitungan menggunakan aplikasi masih cukup tinggi yaitu 99,6%. Adapun perbedaan ini terjadi karena adanya perbedaan mekanisme pembulatan angka desimal di belakang koma pada masing-masing perhitungan.

Published: September 2021

Newspaper printing production processes cannot be separated from the problems that affect printed results and excessive waste. So in a printing company, quality control is needed in order to get good printing results and minimize the amount of waste. The print quality results in a company have several shortcomings such as unsuitable colors, and difficulty to get the register when printing. Apart from the aforementioned shortcomings, there are also factors that cause excessive waste, namely scumming, register disturbances, not sharp printouts, set-off, ghosting, and broken paper. How to solve problems that affect print quality and excess waste by cleaning the ink roll, adjusting the leg according to the proof, adjusting the pressure cylinder pressure, and adjusting the volume of wetting water. From the problems found, the print quality results in a printing company need to be increased so that the amount of waste generated is not too much or too much.Keywords— Print Quality, Waste, Quality Control
Effects of Photoperiod, Water temperature, and Exogenous Hormones on Spawning and Plasma gonadal Steroid in Starry Flounder, Platichthys stellatus

Published: September 2021

The sexual maturation and spawning of teleosts are regulated by the external environment and the endocrine system. When the environmental conditions are artificially adjusted at a fish farm, the maturity and spawning of fish can be controlled. In this study, sexual maturation and spawning of the starry flounder, Platichthys stellatus, were artificially induced by adjusting the water temperature and photoperiod at a fish farm to accelerate the species’ natural spawning period. One experimental group acted as a control and was exposed to a natural photoperiod and natural water temperature (NPNT). In contrast, another experimental group was exposed to an adjusted environment consisting of a regulated photoperiod and temperature (RPRT). Daylight time was reduced by 10 minutes every 3 days from 13 hours to a duration of 8 hours. The water temperature was first reduced by 1oC every day, starting at 22oC and ending at 8oC, and then raised to 10oC until the spawning period. Both experimental groups were treated with gonadotropin-releasing hormone analog (GnRHa) pellets to induce ovulation. The results show that when the water temperature and photoperiod were artificially controlled, ovulation could be induced 97 days earlier than the natural spawning. Plasma testosterone levels of RPRT and NPNT tended to increase and then decrease 1–2 months before spawning, and plasma levels of 17α,20β-dihydroxy-4-pregnen-3-one increased 1–2 months before spawning. The concentration of estradiol-17β (E2) in plasma was not associated with spawning.
Assessing hepatoprotective effects of antioxidants on amiodarone-induced cytotoxicity in human hepatoma HepaRG cell line
Authors: Filimonova KS , Rogovskaya NYu , Beltyukov PP , Babakov VN
Published: September 2021

Effective therapy of amiodarone-induced hepatotoxicity requires studying the mechanisms of the toxic effects of amiodarone on hepatocytes and assessing the potential impact of hepotoprotective agents. The study was aimed to assess hepatoprotective effects of antioxidants on the amiodarone-induced hepatotoxicity with the use of immortalized human hepatoma cells of the HepaRG cell line. Cell viability was evaluated upon exposure to amiodarone and in the mixture with vitamin Е, N-acetylcysteine and S-adenosylmethionine by impedance measurement; the levels of some hepatotoxicity biomarkers were defined using the Luminex xMAP technology. As a result of the research, the dose-dependent toxic effects of amiodarone were established. The IC50 value of amiodarone in the HepaRG cell line was 3.5 μМ. It is shown that cytotoxic effects decrease and the IC50 value increases in the presence of vitamin Е, N-acetylcysteine and S-adenosylmethionine. Amiodarone reduces the activity of cell cycle regulators: AKT, JNK kinases, and p53 protein. Exposure to amiodarone results in reduced intracellular ATP levels and the release of intracellular enzymes (malate dehydrogenase 1, glutathione S-transferase, sorbitol dehydrogenase, 5'-nucleotidase) into conditioned medium, indicating the necrotic cell death. Thus, vitamin Е, S-adenosylmethionine and N-acetylcysteine reduce amiodarone cytotoxicity in the model of amiodarone-induced damage to hepatocytes and can be considered as hepatoprotective agents in case of the need to protect liver against the hepatotoxic effects of amiodarone.

Authors: Dema T Kinley
Published: September 2021

This study explored primary school teachers’ perceptions on e-learning program during COVID -19 pandemic. A qualitative research project was carried out to seek data. The participants were primary school teachers from five regions. To collect the data, semi-structured interview questions using ‘Google form’ were sent to participants through Messenger and E-mail. The responses from the participants indicated that e-learning was one suitable strategy that could be adopted during the crisis era. It was also effective in the development of content knowledge and skills such as digital, self development, problem solving, collaborating and communication skills in students and also teachers. It also assisted teachers and students in exploring the digital world and updating the information. However, the study also confirmed that the implementation of e-learning program encountered several challenges. Teachers perceived adoption of such method as a problem. They felt that inadequate resources, lack of knowledge on technology, technical issues and limited support from the stakeholders were major obstacles to successful implementation of e-learning. Therefore, there is a need to provide timely training for teachers as well as students and provide cost effective internet services available throughout the country. Further, the stakeholders must work collaboratively to make e-learning more effective.

Published: September 2021

Life Skills Education plays a pivotal role in safeguarding children’s personalities the 21st century as they are entrusted with different kinds of adversity such as changes in the global economic, technological transformation, social problems, and critical health issues. Academic success alone is inadequate to meet the difficulties confronted in one’s daily life. Bhutan strongly believes in the well-being of the citizens and Gross National Happiness (GNH) has been the guiding principle in the country’s development and in enhancing values in the Bhutanese children. Along with GNH principle, Life Skills Education plays a significant role in emotional, intellectual, social, and physical development of an individual. Life Skills Education (LSE) has been incorporated in many developing countries including Bhutan and has prepared children to overcome the challenges in everyday life. This article describes LSE and its importance in the educational systems to enable students to develop positive behavioral changes, sound livelihood values, skills, and positive attitudes to deal with critical health issues, make informed use and decisions, and enhance self-esteem in Bhutan.

Authors: Mitzakoff Parola Gabriel
Published: September 2021

This project utilizes integral calculus to find the exact volume of a non-uniform cylindrical-shaped silo used to store wheat and calculate the cost of material utilized to build such silo. Due to its non-uniform shape, the silo is divided into two sections and the volume of each is calculated. The final volume for the silo with the measurements provided is approximately 2330.02 meters cubic and surface area of 1074.96 meters squared, which is considered to be a large capacity silo. With such a large capacity silo there are costs to be considered, such as the material cost which is calculated for steel.
The Abe Experiment and the Future of Japan
Authors: Banno Junji , Yamaguchi Jiro
Published: September 2021

With an author’s Foreword written on the day that the Abe cabinet decided to ‘revise the Japanese Constitution by reinterpretation’ (Tuesday, 1 July 2014), this timely examination of Japan’s post-war history by two leading historians committed to democratic politics is highly instructive and prompts serious reflection by anyone concerned with the future of Japan. Originally published in Japan by Iwanami Shinsho, The Abe Experiment and the Future of Japan, records a wide-ranging dialogue between two eminent Japanese scholars – Junji Banno, a political historian, and Jir? Yamaguchi, a political scientist – regarding Japan’s modern political history. The focus of the conversation is on what they perceive as disturbing parallels between the 1930s and the recent policy trajectory of the Abe government, in which relations with Japan’s immediate neighbours have seriously deteriorated. The translation is by the distinguished Oxford scholar and author Arthur Stockwin, formerly Director of the Nissan Institute.
A.B. Mitford and the Birth of Japan as a Modern State
Authors: Morton Robert
Published: September 2021

Mitford (later to become the first Lord Redesdale) was an urbane aristocrat, had charm, looks and excellent manners. He was always in the right place at the right time, almost drowned, could have burned to death, was shot at, and was nearly cut down by samurai swords. But 'Bertie', as he was known, was never fazed by events. He stood face-to-face with the new, teenage Emperor when almost everybody else, including the Shogun, could only talk to him behind a screen. He became friendly with the last Shogun and witnessed a hara-kiri, his atmospheric account of which is now a classic. An accomplished linguist and writer, Mitford was the outstanding chronicler of the Meiji Restoration, complementing the writings of his contemporary Ernest Satow. This book will be of particular interest to students and readers of Japanese history, as well as readers of nineteenth-century biography in general. It will also have special appeal to those who are familiar with the Mitford family history.

Here is a new, challenging appraisal of Norway, the author’s country of birth, that redefines its history, culture and heritage – ‘after Ibsen’ – and looks, with a degree of ominous foreboding, at its future and the future of Europe. Ex-diplomat and widely published author Jørgensen explores an array of topics, from Norway’s Viking past, its pursuit of independence, the German occupation, its politics and cultural heritage , the defence of NATO, the relationship with Europe, and the challenge of Russia, concluding with ‘self-image and reality’. In Northern Light, the author challenges many existing perceptions and stereotypes, making this an essential reference for anyone interested in Norway and its people, international affairs, European history and its cultural legacy.
The Thames and I
Authors: Naruhito  , Cortazzi Hugh
Published: September 2021

Prior to becoming Crown Prince of Japan in 1989, following the death of his grandfather Emperor Showa, Prince Naruhito studied at Merton College, Oxford, from June 1983 to October 1985. His research topic was the River Thames as a commercial highway in the eighteenth century. This marked the first time that anyone in direct succession to the throne had ever studied outside Japan. In 1992, he published a record of his time at Oxford under the title Thames no tomo ni . The memoir, which includes a colour plate section incorporating photographs taken by the Prince, explores his daily life, studies and recreational experiences, including discovering beer and being banned from entering a disco because he was wearing jeans. The Thames and I is a remarkable record, not least because of its candour, but equally because it reveals the Crown Prince as an individual, including his personal charm and sense of humour. It will be of special interest to those wishing to know more about the future emperor of Japan.

Authors: Pauer Erich , Meade Russelle
Published: September 2021

Drawing on the papers presented at CEEJA’s* first international conference addressing the long-neglected field relating to the generation, dissemination and application of technical knowledge in Japan from the Edo to the Meiji periods, this volume provides a valuable selection of new research on the subject, from Hashimoto Takehiko’s detailed examination of Tanaka Hisashige’s ‘Myriad Year Clock’, Regine Mathias’s paper on mining and smelting, and Erich Pauer’s overview of Japanese technical books in the pre-modern era, to Suzuki Jun’s detailed account of boiler-making in late nineteenth-century Japan. * Centre Européen d’Études Japonaises d’Alsace, 2017
Early Japanese Trade, Administration and Interactions with the West
Authors: Cullen Louis
Published: September 2021

Throughout his academic career Louis Cullen’s main research interest has been foreign trade - originally that of England, Ireland and France, but from the mid-1990s, his focus turned to Japanese history resulting in his critically acclaimed A history of Japan 1582–1941: Internal and External Worlds. Subsequently, he concentrated on the analysis of archival sources and of the problems they pose for the interpretation of Japanese history: papers on some of these themes and their associated statistical dimensions have appeared in Nichibunken’s Japan Review and are republished here together with a collection of other papers including interpreting Tokugawa history and the knowledge and the use of Japanese by the Dutch on Dejima island.
FERTILIZANTE ORGANOMINERAL NO DESENVOLVIMENTO DE MUDAS DE MELÃO
Authors: Silva Bruna de Jesus
Published: September 2021

Introdução: O melão é uma olerícola consumida como fruta, muito importante ao mercado nacional e mundial. Para essa e qualquer outra cultura a produção de mudas é uma etapa importante do sistema de produção, pois é umas das etapas que necessitam de um bom manejo para que a cultura atinja bom desenvolvimento, ciclo uniforme, qualidade, vigor e excelência na produtividade. Dentre as práticas de manejo nesta etapa, o uso de produtos, como organominerais líquidos ainda é recente. Objetivos: Perante a isso, objetivou avaliar a consequência de diferentes dosagens do fertilizante foliar organomineral LANNOITE® no desenvolvimento de mudas de melão Eldorado 300, com propósito de alcançar resultados significativos, afim de agregar maior produtividade. Materiais e Métodos: O experimento foi conduzido no município de Uberlândia, Minas Gerais. Implantando no dia 01 de maio de 2020, com avaliação aos 30 DAS (dias após a semeadura). Utilizou-se bandejas com 100 células e substrato Bioplant plus, delimitando o experimental em (DIC), com quatro tratamentos e cinco repetições, dispondo as doses de forma: (Testemunha) T1-0; T2 -0,50 mL; T3-0,75 mL e; T4-1 mL. Foi necessário diluir o produto em proporção de 1.1. A média de comprimento da raiz (MCR), massa verde total (MFT), massa seca total (MST) e a média de número de folhas (MNF), foram os parâmetros de avaliação. Resultados: Ao fim da pesquisa, os resultados obtidos foram: T1- (MCR) 4.46, (MNF) 2, (MST) 0.89, (MFT) 79.74; T2-(MCR) 4.46, (MNF) 2.2, (MST) 0.75, (MFT) 69.91; T3- (MCR) 4.34, (MNF) 2.6, (MST) 0.75, (MFT) 64,17; T5- (MCR) 3.024, (MNF) 2.2, (MST) 1.15, (MFT) 99.58. Ao analisar os dados, observou que a dose de 1mL obteve resultado significativo em (MST) e (MFT), e as demais doses não auferiram resultados significativos em nenhum dos parâmetros. Conclusão: Conclui-se então que a aplicação do fertilizante organomineral na cultura do melão não altera significativamente o número de folhas e o comprimento de raiz em doses menores ou iguais a 1mL, mas na produção de massa de forragem e massa seca, a dosagem de 1mL mostra-se promissora para o aumento da eficiência.

Augmented Reality is an exciting technology that has been booming in recent years and might just be the solution to bridging the gap between the experiences in online and offline shopping, education, entertainment, and many more. AR can be used to market a variety of products, one of them is food. AR has been used by many big tech companies like Snapchat and Instagram to enhance the user experience using computational power. One feasible application of this technology in the advancement of the food industry is by displaying a food sample all the more alluring and how the food would look like in cafés and restaurants using 3D models of these foods. In this paper, we explore, and discuss existing systems in the food industry and challenges in developing such systems. We propose one of the feasible uses of this technology in the development of the food industry is to use 3D food models to show a food sample and how the food will appear in cafés and restaurants. Food Magic will encourage customers to view abstract food in the restaurant as more appetizing when exploring, buying, taking out or eating. We also present other important aspects, including key requirements for successful deployment of Food Magic. Finally, open research issues are outlined.

With the speedy increase of wind energy in electric networks, many important issues could emerge, where the most important matter is to maintain the connection of wind generators during fault conditions. With different faults in the electrical network, the voltage at the point of common coupling (PCC) decreases causing unwanted transients in the stator currents. This results in substantially increased fluctuations in the DC-link voltage (Vdc). To avoid this negative impact, it is a must to maintain the capability of wind generators to continue linked to the network during faults, which is depicted as low voltage ride through (LVRT) capability. This paper investigates the LVRT enhancement by two techniques, the first is based on Braking Chopper (BC) and the second method is based on electrical double-layer capacitors (EDLC), or Supercapacitor Energy Storage System (SCESS), under abnormal conditions. The full model of the permanent magnet synchronous generator (PMSG) system and FRT technique are performed in MATLAB/Simulink platform. As a consequence of the findings, both the BC and SCESS are capable to provide satisfactory performance with superior FRT capability for the SCESS compared to the BC.
