Nonlinear Cone Model for Investigation of Runaway Electron Synchrotron Radiation Spot Shape
Authors: Pankratov Igor M. , Bochko Volodymyr Y.
Published: August 2022

The runaway electron event is the fundamental physical phenomenon and tokamak is the most advanced conception of the plasma magnetic confinement. The energy of disruption generated runaway electrons can reach as high as tens of mega-electron-volt and they can cause a catastrophic damage of plasma-facing-component surfaces in large tokamaks and International Thermonuclear Experimental Reactor (ITER). Due to its importance, this phenomenon is being actively studied both theoretically and experimentally in leading thermonuclear fusion centers. Thus, effective monitoring of the runaway electrons is an important task. The synchrotron radiation diagnostic allows direct observation of such runaway electrons and an analysis of their parameters and promotes the safety operation of present-day large tokamaks and future ITER. In 1990 such diagnostic had demonstrated its effectiveness on the TEXTOR (Tokamak Experiment for Technology Oriented Research, Germany) tokamak for investigation of runaway electrons beam size, position, number, and maximum energy. Now this diagnostic is installed practically on all the present-day’s tokamaks. The parameter v┴/|v||| strongly influences on the runaway electron synchrotron radiation behavior (v|| is the longitudinal velocity, v┴ is the transverse velocity with respect to the magnetic field B). The paper is devoted to the theoretical investigation of runaway electron synchrotron radiation spot shape when this parameter is not small that corresponds to present-day tokamak experiments. The features of the relativistic electron motion in a tokamak are taken into account. The influence of the detector position on runaway electron synchrotron radiation data is discussed. Analysis carried out in the frame of the nonlinear cone model. In this model, the ultrarelativistic electrons emit radiation in the direction of their velocity v→ and the velocity vector runs along the surface of a cone whose axis is parallel to the magnetic field B. The case of the small parameter v┴/|v||| (v┴/|v|||<<1, linear cone model) was considered in the paper: Plasma Phys. Rep. 22, 535 (1996) and these theoretical results are used for experimental data analysis.

The Itinerant Curriculum as a Key to Responsiveness in the Era of the Fourth Industrial Revolution in Nigerian Higher Education
Authors: Fomunyam Kehdinga George
Published: August 2022

The current age of the Fourth Industrial Revolution (4IR) brings together digital, physical, and biological awareness in ways never before seen. The transition has contributed to new technology and developments, such as robotics, the Internet of Things, augmented reality, and artificial intelligence. As a nation, Nigeria is still behind with preparations for its future through appropriate, unique educational practices in this era for its citizens. This is because the quality of Nigeria’s higher education curriculum has not improved much. To boost the responsiveness of Nigeria’s curriculum in this technological era, this theoretical paper explores the itinerant curriculum as an alternative direction to other highlighted alternatives in the literature. The paper explains how the itinerant curriculum can be used to achieve economic, cultural, disciplinary, and learning responsiveness in the era of the 4IR. The paper concludes that the itinerant curriculum is an important tool that can help Nigerian higher education achieve curriculum responsiveness.
Self-Explaining Photosynthesis to Achieve Conceptual Change: An Analysis of Explanation Content
Authors: Oliver Merrin , Troemel Virginia
Published: August 2022

Students enter biology coursework with various misconceptions needing revision. However, achieving conceptual change of these misconceptions in the classroom is notoriously difficult and requires specific instruction. Self-explanations can promote conceptual change, but their effects can depend on the content produced. This study investigates how the content of learners’ explanations of photosynthesis processes affects learning. We examined data from an online assignment in introductory biology where 118 college undergraduates answered multiple-choice questions related to commonly misconceived processes in photosynthesis and respiration and were then prompted to self-explain the correct answer. One week later, students took a test that measured learning in the activity. Using mixed methods analyses, we qualitatively explored the types of explanations learners made, categorized the different types of explanations, and performed quantitative analyses to examine relations between explanation content and test scores. We identified five categories of self-explanations that varied in engagement, accuracy, and focus. Accuracy of the explanation mattered; accurate explanations predicted higher test scores, and inaccurate explanations predicted lower test scores. We also identified three different groups of learners: highly performing learners who were actively engaged and accurate; moderately performing learners who were engaged but often paraphrased or explained inaccurately; and low performing learners who were disengaged and avoided explaining. We provide implications for use of self-explaining misconceived material.

Internet of Things Based Transducer Application to Harness Tidal Energy from coastal and offshore Pakistan
Authors: Kumar Suresh , Khan Irfanullah , Danish  , Aslam Alveena , Majid Muhammad Imran
Published: August 2022

This paper aims to transform tidal energy into rotation energy for electricity generation and in the course evaluating sea parameters. This is accomplished by integrating the Internet of Things with tidal energy off the coast (and in a home environment), which further enhances the capabilities of this prototype project to remotely monitor sea-like parameters to enable energy production using tidal energy. As South Korea is transducing tidal energy with a total installed tidal power capacity of above 500MW, Pakistan and Middle Eastern countries can benefit from its vast coastal line. This paper proposes a sustainable design that makes the turbine rotate at high speed. A vertical design is chosen, which is bi-directional. The design of the turbine consists of 3 blades, each occupying a 2 square feet area supported by an iron-rod frame. During the experimentation, an average voltage of 5V was generated, whereas the speed of the turbine generated was 75 RPM. It is the first known attempt of its kind supported by indigenous resources. It is proposed that this type of prototype can be scaled, to the coast to produce electrical energy to meet the energy production needs of the region.

Published: August 2022

Many researchers have made efforts to generate genotype-matched and subunit vaccines for Newcastle disease (ND). During the design process, we found that they only considered certain characteristics of the virulent strains. As a result, the resulting vaccines are still poorly effective against new emerging strains of ND virus (NDV). This analysis suggests that consideration of various characteristics of virulent strains in the design is necessary to increase the efficacy of these new vaccines. Thus, analysis of mutations in viral proteins targeted in the design such as fusion proteins (F) and hemagglutinin-neuraminidase (HN) is essential. For this reason, the present study aims to analyze mutations in these two proteins in twelve NDV strains isolated in Madagascar. To achieve this, we employed bioinformatics methods such as sequence alignment, molecular modeling, 3D structure comparison and mutation impact prediction via bioinformatics software and servers. As results, we identified respectively 26 and 41 mutations in the F and HN proteins of the Madagascar isolates. All these mutations have an impact on the stability of the protein. However, only 6 mutations (D344N, G303V, P315S, E347K, P391S and E495S) have an impact on their 3D structures. Finally, the 3 mutations (A477T, G303V and P315S) also affect the functions of these two proteins. In conclusion, we have identified 67 mutations that may affect the stability, structures, and functions of NDV F and HN proteins. Further studies are needed to know their effects on the antigenicity and immunogenicity of these two proteins.

Objective: To analyze the clinical features of de novo lung neuroendocrine tumor (NET) after liver transplantation (LT) for hepatocellular carcinoma (HCC).

Method: Retrospectively reviewed the clinical data of the 1253 patients who underwent LT from 2013 to 2022 in our institute.

Result: Out of 1253 recipients of LT 7 patients suffered de novo lung carcinoma, of these 2 patients suffered lung NET accounting for 28.6% (2/7) of de novo lung carcinoma both at extensive stage. New on-set lung lesions and hilar and mediastinal lymphadenopathy were found by imaging tests; and were diagnosed as lung NETs in both patients through pathological examination. The interval between LT and diagnosis of lung NET ranged from 5.9 to 44.7 months. Both patients received cisplatin and etoposide as first-line chemotherapy and achieved partial remission. The progression-free survival period ranged from 1.9 to 2.2 months. Survival after diagnosis of lung NET ranged from 7.0 to 10.9 months. One of the patients tried to cease immunosuppressants during chemotherapy and incurred graft rejection.

Conclusion: Lung NET may have a higher proportional incidence of de novo lung carcinoma in LT recipients. Early diagnosis is vital for the treatment of lung NET, while predictive and timely biopsy based on imaging findings is crucial for making an early diagnosis.

Textual Exchanges in Late Antiquity East and South of Byzantium Seen Through an Eastern Christian Lens
Authors: Debié Muriel
Published: August 2022

Scientific and philosophical texts circulated as is expected between the Roman and Sasanian empires as well as more east and west towards Europe and towards India and China. Arabia, though still often absent from the mental map of Late Antiquity, was also involved in exchanges of written texts, mainly letters. It is more surprising to see that religious texts were also discussed in the courts. Byzantium engaged in geopolitical and religious dialogue with its eastern and southern neighbours through clerics who played also a role as ambassadors of knowledge and cultural delegates. Syriac texts written in the eastern Roman empire or east of Byzantium offer a slightly decentred picture of these relations viewed from and beyond the borders of empires.

If the government makes good laws and regulations, the community will always comply with these regulations. Taxes are things that are regulated in laws and regulations. In this case, taxes are an obligation for the community to pay them. The type of research in the legal article entitled Juridical Analysis of the Compliance Level of Paying Taxes for the Indonesian Society is doctrinal or normative legal research. Taxes themselves have essential benefits for the development of the Indonesian state because taxes are a source of state treasury income which is ultimately used for public welfare. This study aims to determine the benefits of taxes, government efforts, and the influence of the Indonesian people's understanding of the importance of paying taxes to create public welfare in Indonesia.

Flood is associated with the climatic change where the climate variable has detrimental impact on hydrologic cycle. Johor is among the affected states by flood catastrophe for almost every year. Over the year, Johor has experienced increasing amount of rainfall. However, studies on future rainfall pattern in Johor are still quite limited. Thus, this study was carried out to identify climate change impacts by projecting rainfall data using Statistical Downscaling Model (SDSM) and predicting flood events utilizing the Standardised Precipitation Index (SPI). Through SDSM, the rainfall data was projected in corresponding with General Circulation Models (GCM) predictor under three different representative concentration pathway (RCP) of RCP2.6, RCP4.5 and RCP8.5 that consider different emission level in future. Future observation in the upcoming 30 years for both studied stations at Kota Tinggi, Johor recorded increasing trend in the projected mean annual rainfall under three scenarios where the highest change in projection was +12.2% under RCP8.5 at Ladang Telok Sengat station. From SPI analysis, it is predicted that there will be frequent occurrence of flooding in the upcoming 30 years due to more positive SPI values (> 1) indicated by the studied stations. From the study, the authorities can come up with better mitigation plan to supervise the flood event in the future.

The study objective is to analyze the efficiency of installing stretch ceilings in industrial buildings of transport engineering enterprises constructed in the 60s...70s of the previous century as one of the ways of building insulation. The problem to which the paper is devoted is the development of a method for calculating heat losses during the installation of a stretch ceiling in a production building of a transport engineering enterprise, a comparative analysis of these losses before and after the ceiling installation. Research methods: the paper uses a computational and theoretical method of heat transfer studies, in which, after passing the stretch ceiling, the heat flow is divided into two unequal parts, because the thermal resistance of the walls and roof is different. The novelty of the work: a method for calculating heat losses when installing a stretch ceiling in a production building is proposed. Study results: it is found that the installation of a stretch ceiling allows not only to improve the aesthetic appearance of an industrial building, but also to reduce heat losses through the upper part of the building and the roof by almost 1.5 times. Conclusions: the installation of stretch ceilings with insulation in industrial buildings of transport engineering enterprises has a thermal feasibility, since at the same time heat losses are significantly reduced.
