Legitimation Strategies in Political Rhetoric: Examples From Presidential Speeches on Covid-19
Authors: Wang Yunyou
Published: May 2022

Heads of states are currently focusing on containing the spread of the coronavirus pandemic-commonly called Covid-19, and grappling with a series of strategies for addressing the pandemic. Political discourse concerning Covid-19 can be examined to better understand the ideology of the speaker and its impact on the audience. In this paper, we use Van Leeuwen’s (2007) and Van Leeuwen and Wodak’s (1999) legitimation strategies that social actors use to justify courses of action/political decisions in a critical discourse analysis approach. Drawing on presidential speeches specifically made by Donald Trump (USA) and Xi Jinping (China), this paper elucidates how legitimation strategies are linguistically constituted and fashioned to justify the leaders’ particular policy decisions and actions for controlling and containing the spread of the coronavirus pandemic, thus achieving their political goals.

Published: May 2022

This research discusses the lexicon used for traditional technology systems in the Tolaki community. Lexicon is a language component containing information about the meaning and usage of words, the richness of words a language has. Lexicon runs into a shift due to certain factors such as changes in norms, culture, and environment and the development of science and technology. The level of shift and the change in the meaning of the lexicon for traditional technology systems in Tolaki community, Konawe Regency, Southeast Sulawesi are analyzed with the method of qualitative descriptive analysis. The data are taken from written sources, literature studies, by examining and recording some lexicons from the book "Tolaki Culture" by Abdurrauf Tarimana. This book discusses the lexicon used for traditional technology systems in the Tolaki community. The validation of the data is then substantiated by questionnaire distribution in which the informants fill in lexicon data for agricultural technology systems and imply them in Tolaki language. The lexical-semantic theory by Pateda is applied and the results of the data analysis show that the lexicon for agricultural technology system in Tolaki is extinct and undergoing a shift. 115 lexicons of traditional technology systems are analyzed and among them are 50 (44%) lexicons undergoing extinction, 29 (25%) undergoing a shift, and 36 (31%) undergoing no shift.

Published: May 2022

Diante da destinação inadequada de resíduos sólidos que trazem consigo prejuízos ao meio ambiente, objetivou-se, neste trabalho, realizar a estimativa de produção de biogás dos resíduos sólidos urbanos da cidade de Pau dos Ferros (RN), tal como avaliar o seu potencial de aproveitamento energético. Como metodologia, foram realizadas as estimativas do crescimento populacional e sua posterior geração de resíduos, almejando calcular a emissão de metano e biogás. Para tal, utilizou-se o modelo LandGEM para os cálculos de estimativas dos gases gerados pelos resíduos. A avaliação foi realizada mediante três cenários: destinação da totalidade dos resíduos para aterro sanitário (1), destinação de resíduos orgânicos alimentares para compostagem (2) e destinação da totalidade de resíduos para pirólise (3). Como resultados, observou-se que o cenário que apresentou maior produção de biogás foi o cenário 1, devido à elevada carga orgânica presente na composição dos resíduos. Enquanto o cenário 2 apresentou menor produção de gases em relação ao cenário 1, a reduzida geração de biogás ocorre devido a retirada da fração orgânica dos resíduos que seriam encaminhados para compostagem, essenciais para a produção desse gás. Já o cenário 3 apresentou menor emissão de biogás devido o mesmo receber apenas o resíduo resultante do processo de pirólise e que não possui grande potencial de geração de biogás. Com relação ao potencial energético dos resíduos, é possível que os mesmos possam ser utilizados para a geração de eletricidade dentro do próprio aterro.

Considerando a importância econômica da cultura do milho (Zea mays L.) para o Estado do Tocantins e a escassez de estudos sobre o efeito da adubação nitrogenada e da utilização de bactérias do gênero Azospirillum, para a fixação biológica de nitrogênio, trabalhos de pesquisas são necessários. Neste sentido, o presente estudo foi realizado com o objetivo de se avaliar o efeito da adubação nitrogenada, associada ou não à bactéria Azospirillum brasiliense, no teor de proteína dos grãos de milho, na entressafra 2015, em Palmas (TO). Foram conduzidos dois ensaios no delineamento experimental utilizado de blocos casualizados com 30 tratamentos e três repetições. Os tratamentos foram dispostos em um esquema fatorial 2x3x5, representado por dois processos de inoculação das sementes no sulco no momento da semeadura com Azospirillum brasilense, três cultivares de milho e cinco doses de N realizadas em cobertura. O teor de proteína nos grãos foi obtido segundo o método de Kjeldahl. Temperaturas menores durante a fase vegetativa favoreceram o acúmulo de proteína nos grãos. O híbrido AG 1051 apresentou um maior incremento no teor de proteína nos grãos em função de doses de N na ausência do Azospirillum brasiliense. A variedade Al Bandeirante, em virtude de sua rusticidade, apresentou um maior conteúdo proteico nos grãos sob baixa disponibilidade de N na presença ou ausência do Azospirillum brasilense. A inoculação de sementes de milho com Azospirillum brasilense poderá ser uma alternativa viável na redução do uso de fertilizantes nitrogenados.

O gênero Mentha inclui plantas utilizadas pelas indústrias químicas, farmacêuticas e alimentos, multiplicadas por propagação vegetativa, pois tais plantas produzem um considerável percentual de sementes estéreis. O objetivo deste estudo foi avaliar o desempenho de diferentes concentrações de compostos orgânicos e dos minerais nitrogênio e boro no desenvolvimento de mudas de menta, produzidas por estaquia. As estacas foram confeccionadas com a parte mediana do ramo, padronizadas com 10 cm de comprimento e três a quatro nós. Nos tratamentos foram utilizadas duas formulações líquidas comerciais, solúveis em água, a primeira contendo carbono orgânico foi utilizada nas doses de 0; 0,025; 0,05; 0,10%. Na segunda com nitrogênio e boro empregou-se as doses de 0; 0,03; 0,06; e 0,12%. Como controle foi utilizada água destilada. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 2 x 4 (formulações e doses), com quatro repetições de sete estacas para cada tratamento. Foram avaliados o número de folhas, de brotos, altura da parte aérea, comprimento da maior raiz, biomassas das matérias frescas e secas da parte aérea, e do sistema radicular. Os dados foram submetidos à análise de variância e as médias agrupadas pelo teste Scott-Knott a 5%. Os efeitos das doses de cada formulação foram submetidos à análise de regressão. A adição ao substrato dos minerais nitrogênio e boro nas concentrações 0,03% e 0,06%, logo após a estaquia, pode ser recomendada com o objetivo de estimular a expansão do volume do sistema radicular e desenvolvimento da parte aérea, produzindo mudas de menta com qualidade comercial satisfatória.

Published: May 2022

As discussões envolvendo questões ambientais em cemitérios vêm crescendo nas últimas décadas. Cemitérios mais antigos, datados antes da década de 1820, foram concebidos em épocas que não existiam normas específicas para a localização e instalação. Aspectos e impactos ambientais não eram levados em consideração e, consequentemente, esses locais tornaram-se fontes potenciais de contaminação ambiental. Nesse sentido, este estudo objetivou identificar os impactos ambientais gerados no cemitério de um município no Rio Grande do Sul. As informações relatadas são de fundamental importância para o município, pois o estudo apresenta a atual situação ambiental do único cemitério municipal, podendo auxiliar os órgãos competentes à tomada de decisão acerca dos riscos ambientais envolvidos e ainda ser usado como subsídio no enquadramento das normativas ambientais. A metodologia aplicada foi pesquisa bibliográfica de documentos relacionados ao objeto de estudo e pesquisa-ação, dividida em 4 etapas: análise histórica da documentação referente ao cemitério municipal, mapeamento da área, análise quanto as legislações vigentes e análise dos impactos ambientais gerados. Um dos problemas identificados no cemitério municipal é a impossibilidade de ampliação por ser uma área consolidada e construída na década de 20, localizada na área urbana do município. Verificou-se ainda que, dos 19 itens para atendimento aos critérios legais, o cemitério municipal atende 1 item de maneira integral, 5 itens de forma parcial e 13 itens não atendem a legislação. Contudo, observa-se que o cumprimento das questões ambientais e o gerenciamento de resíduos gerados precisam ser realizados para minimização dos impactos ambientais, sociais e econômicos.

O sistema de produção de mudas de cana-de-açúcar via minitoletes apresenta-se como uma interessante alternativa ao sistema de plantio convencional, o qual requer grande quantidade de material de propagação, porém o sistema alternativo demanda quantidades significativas de substrato para o desenvolvimento vegetativo inicial da cana. Nesse sentido, o objetivo do presente trabalho foi determinar o potencial de dois compostos orgânicos na elaboração de substratos para a produção, a partir de minitoletes, de mudas de cana-de-açúcar genótipo RB966928. Os resíduos utilizados para a produção dos compostos orgânicos foram: bagaço e palha de cana-de-açúcar, serragem, casca de acácia, cama de aviário e torta de tungue. Na formulação dos substratos adicionou-se diferentes proporções de cinza de casca de arroz e casca de arroz carbonizada aos compostos, resultando em oito substratos, nos quais foram avaliados os parâmetros físico-hídricos, pH e condutividade elétrica. Como controle utilizou-se um substrato comercial. Os ensaios de eficiência agronômica foram conduzidos em casa de vegetação durante 70 dias e as variáveis agronômicas avaliadas foram: porcentagem de brotação, número de folhas, diâmetro do colo, altura, massa fresca e seca da parte aérea e massa seca da raiz. Os substratos apresentaram pH, condutividade elétrica e características físico-hídricas satisfatórias, refletindo no desenvolvimento das mudas, em que os substratos a base de compostos orgânicos proporcionaram respostas agronômicas iguais ou superiores ao substrato comercial. Os substratos formulados com as doses de 100% composto orgânico 1 e 75% composto orgânico 1 + 12,5% casca de arroz carbonizada + 12,5% cinza de casca de arroz apresentam maior potencial para produção de mudas de cana-de-açúcar.

Published: May 2022

O objetivo principal deste estudo foi analisar as alterações da marcha de adultos com hemiparesia após acidente vascular encefálico (AVE) e comparar com sujeitos saudáveis. A amostra foi composta por 14 participantes do grupo AVE e 14 participantes pareados do grupo-controle (CON). Foi realizada uma análise tridimensional da marcha mediante um sistema de cinemetria. Os parâmetros analisados foram a velocidade, o comprimento da passada, a largura da passada, a cadência e o tempo da passada, sendo utilizado o teste t independente para as comparações entre os grupos e considerando p < 0,05 como critério de decisão. Os participantes do grupo AVE apresentaram valores médios significantemente inferiores em todos os parâmetros analisados. Além disso, os pacientes do grupo AVE também tiveram valores muito inferiores quando comparados aos de outros estudos com pacientes pós-AVE, possivelmente devido ao curto período entre o AVE (média de 14,14 meses) e a avaliação da marcha.

To evaluate the effects of different amplitude-modulated frequency (AMF-100Hz and AMF-10Hz) of the interferential current (IC) on autonomic nervous system (ANS) in healthy volunteers. Thirty healthy volunteers (23.7 ±2.7 years old) were randomized into placebo interventions (turned off), IC with AMF-100Hz and IC with AMF-10Hz. Interventions ware applied in the paravertebral ganglionar region for 30 minutes. ANS evaluated by the heart rate variability before and immediately after the interventions. 10Hz intervention reduced the sympathetic activity in 6% and an increase in the parasympathetic in 6%. 100Hz intervention increased 12% to sympathetic activity and decreased 12% to parasympathetic activity. IC changes the autonomic balance in healthy volunteers. 10Hz reduces the sympathetic activity and increases parasympathetic, although the 100Hz has opposite results. The IC at 10Hz improves the autonomic balance and presents potential effects to be tested in hypertensive patients.

Este estudo teve como objetivo avaliar a resposta da temperatura da pele (Tsk) nas coxas (músculo quadríceps) após a massagem terapêutica unilateral através da imagem térmica. A massagem terapêutica unilateral na coxa esquerda foi realizada em voluntário saudável (51 anos) submetido a uma sessão de massagem terapêutica unilateral (deslizamento – Effleurage; e o amassamento - Petrissage) na coxa esquerda. As capturas das imagens térmicas foram realizadas nos seguintes momentos: pré-massagem, pós-massagem imediato, 5 minutos,10 minutos, 24 horas e 48 horas após a realização da massagem. As regiões de interesse analisadas foram as coxas direita e esquerda. Os resultados mostraram um aumento significativo da Tsk na coxa esquerda pós-massagem imediato e um aumento discreto na coxa contralateral nos intervalos analisados. A simetria térmica foi evidenciada em 48 horas após a massagem. Pode-se concluir que a massagem terapêutica promove mudança na Tsk com magnitude suficiente para ser mensurada instrumentalmente. A termografia infravermelha demonstrou ser uma ferramenta útil na avaliação da resposta víscero-cutânea antes e depois da sessão de massagem, possibilitando avaliar os efeitos de uma força mecânica manual sobre a Tsk.

Published: May 2022

The UV/VIS spectrophotometric scans were obtained to determine the opto-electronic properties of 2-oxo-2-(1-oxo-1H-isochromen-3-yl)ethyl methacrylate (other name: 2-(isocoumarin-3-yl)-2-oxoethyl methacrylate) compound thin film. The refractive index of compound at 700 nm was found to be 1.61. The values of the real part of the dielectric constant were higher than those of the imaginary part. The results indicated that the electronic transition responsible for the absorption was the indirect allowed one. The optical band gap constant and the Urbach energy corresponding to the width of the band tails of localized states were calculated to be 3.19 eV and 1.05 eV, respectively. From the results obtained, it is predicted that 2-oxo-2-(1-oxo-1H-isochromen-3-yl)ethyl methacrylate (OICEMA) compound can take place in the semiconductor class and play a role in the design of some electro-optic materials.

Published: May 2022

The purpose of this paper is to examine the role that religion plays in the working lives of Muslim employees, by exploring the influences of Islamic values on employees Organisational Citizenship Behaviour. This is a largely quantitative study conducted in Jordanian organisations. The study introduces a theoretical model drawing parallels between Organisational Citizenship Behaviour and Islamic Work Ethics. The participants, comprising of employees of Jordanian public and private sectors, have been randomly invited to express their views on the possible penetration of Islamic values in the workplace. A Partial Least Squares approach alongside a bootstrapping technique was used to analyse the data. The validity of the measurement model was tested using the Fornell and Larcker criterion. Findings indicate that Islamic values do influence the citizenship behaviour, organisational commitment and loyalty to the organisation of employees. Motivated by religion employees are more likely to adopt discretionary citizenship-alike behaviours in the workplace and be loyal to their organisation. The scope of this study is limited by its primary focus of developing an Islamic perspective within the domain of Organisational Citizenship Behaviour, which utilises the Islamic Work Ethics framework rather than being grounded in Islamic holy texts. This paper not only provides a useful insight into the link between religious motivation, citizenship behaviour, and organisational commitment and loyalty, but also notes the influence of religion in the workplace.

Published: May 2022

Background: Nowadays, many individuals are moving toward business relationships, becoming closer and developing business ties with their business partners in the supply chain. Relationship marketing could underpin strategic marketing in minimizing economic problems and enhancing business performance. However, there is little emphasis on how relationship marketing constructs influence paddy farmer’s business, specifically theory-based empirical research. Therefore, the objective of this study is to examine the relationship between relationship marketing components (trust, communication and satisfaction) and paddy farmer’s farm performance in Bangladesh. Methods: A validated survey instrument was used for data collection and 356 paddy farmers were interviewed applying systematic random sampling from the district of Mymensingh in Bangladesh. Partial Least Square Structural Equation Modeling (PLS-SEM) was used in data analysis. Result: The findings revealed that trust, communication and satisfaction had direct relationships with farmers’ farm performance. It was also revealed that satisfaction was a mediator in the indirect relationship between trust and performance. In enhancing farmer’s farm performance, this study suggested that it would be beneficial to practice a long-term relationship marketing strategy instead of a traditional marketing approach in the agriculture context.

Published: May 2022

Background: Swine pasteurellosis, caused by Pasteurella multocida capsular types A and D, causes heavy economic loss to the pig farmers. The vaccine presently used is a bacterin of Pasteurella multocida capsular type B that is proven to be effective against bovine pasteurellosis. However, its efficacy against swine pasteurellosis is questionable. Methods: The present study was carried out to evaluate the efficacy of calcium phosphate nanoparticle adjuvanted bivalent subunit vaccine prepared from Pasteurella multocida capsular types A and D along with a monovalent subunit vaccine prepared from Pasteurella multocida capsular type B in mice. The Alum precipitated bacterin vaccine was used as the control. Result: The bivalent subunit vaccine showed significantly higher serum IgG response than either of the other two vaccines. The calcium phosphate nanoparticle adjuvanted vaccines could elicit 100% protection in mice against homologous challenges but the aluminum hydroxide adjuvanted bacterin vaccine could not elicit significant protection. Based on this preliminary work, it was concluded that the bivalent subunit vaccine would be a better option for immunization of swine against swine pasteurellosis.

Published: May 2022

Background: To meet the requirements of sustainable growth for feeding the increasing population in a changing world, farmers and scientists have developed many eco-agricultural practices. Although researchers have developed many eco-agricultural techniques, there remain challenges in terms of integrating their advantages and overcoming their limitations. Here we advocate the intercropping of groundnut and blackgram with different crop ratios to study the production potential and economics of groundnut cum black-gram based intercropping system. Methods: The experiment was laid out in 2020-2021 with random block design consisting twelve treatments comprising of groundnut as base crop and blackgram as intercrop in the replacement series or crop ratios of 3:1, 3:2, 4:1, 4:2, 5:1, 5:2, 6:1, 6:2, 7:1, 7:2 row proportions and their sole crops viz., groundnut and blackgram. Each treatment is replicated thrice. Result: The productivity in terms of groundnut yield was significantly higher with 4:1 replacement series followed by 6:1 and 7:1 than other replacement series. The biological efficiency in terms of LER and ATER were also recorded maximum values and indicated a modest aggressivity and CR and gave a good value for the product of RCC with 4:1 followed by 6:1 and 7:1. The economics of the systems also indicates that groundnut + blackgram with replacement series of 4:1 was most profitable system in terms of gross return, net return, B:C ratio and MER followed by 6:1 and 7:1.

Published: May 2022

Autonomous vehicles are considered a viable technological option to implement first/last mile transportation in the cities of tomorrow with a high population density, and for this reason it is essential that they have a robust localization system for the routes first-mile transport and last-mile transport points, and the route’s planning and navigation. This article presents the implementation of an outdoor parking localization system which uses a map based on geo-referenced landmarks (road marking poles with reflective tape) and an Extended Kalman Filter, fed with both odometry and 3D LiDAR information. The system was evaluated in nine routes with distances between 85 m and 360 m, in which an error was obtained between the ground-truth and the algorithm’s estimated position below 0.3 m and 0.5 m for the position in X and Y coordinates, respectively. The results show that this is a promising method that should be tested in larger settings using both natural and artificial landmarks.

Published: May 2022

Este trabajo propone el uso de una interfaz cerebro computador, que permite medir las neuroseñales del nivel de compromiso en el desempeño del teleoperador al realizar la tarea. La metodología para determinar el nivel de asistencias hápticas consta de 4 pasos: primero se selecciona una aplicación de teleoperación, que consistía en mover a distancia un robot a lo largo de una trayectoria predefinida. En los pasos dos y tres, se ejecuta la tarea planteada con y sin asistencias hápticas. En el paso 4 se analizan los recorridos del robot, para determinar las zonas donde el operador requería un mayor o menor nivel de asistencia. Los resultados muestran que al usuario le toma un tiempo significativamente mayor el realizar el recorrido planteado, cuando no tiene activas las asistencias hápticas. Se concluye que las interfaces cerebro computador, permiten detectar las zonas donde estas ayudas se hacen más necesarias y las zonas donde se pueden disminuir.

Desde el Programa Etnomatemática se ha destacado el potencial de reconocer y utilizar las matemáticas presentes en diversas prácticas culturales propias de cada país para fortalecer su enseñanza y aprendizaje. En países como Chile, la pesca es una tarea que ocupa a muchos de sus habitantes. No obstante, el potencial de esta práctica para abordar los aprendizajes matemáticos propuestos en el currículo nacional no ha sido investigado. Con el propósito de explorar elconocimiento matemático de los pescadores de la bahía de Puerto Montt, Chile, y al seguir una metodología cualitativa con un enfoque etnográfico, se implementaron entrevistas semiestructuradas a siete pescadores de esta zona. Los datos se analizaron según un análisis temático. En los resultados se evidencia que los pescadores tienen conocimientos matemáticos asociados a la mayoría de los ejes que conforman el currículo nacional de matemáticas de educación básica en cuanto al estudio de la medición —convencional y no convencional—, la localización —orientación espacial—, el conteo,el modelado —relaciones entre variables y conversiones— y la estimación —de medidas y de cantidad—, entre otros. Finalmente, se proponen algunas directrices de cómo vincular estos conocimientosal currículo nacional.

En el siguiente informe de tesis, se presenta el desarrollo de un concreto especial reforzado con fibra de basalto para evitar la corrosión en los elementos estructurales encontrados en la ciudad de Pisco. Este material es clasificado como polímero utilizado para mejorar las propiedades físicas y mecánicas del concreto. Por ello, los ensayos en probetas estándar de concreto con diferentes porcentajes de este adicionado generan resultados eficientes que comprueban la hipótesis a investigar. Como punto de referencia y comparación también se evaluó un concreto convencional. En ambos casos fueron sometidos a los ensayos de compresión y tracción para medir su resistencia. Además, se realizaron ensayos para medir su durabilidad tales como álcali-sílice y carbonatación. Los resultados generan beneficios en la actividad de la construcción y minimizan los costos económicos surgidos por la pérdida de materiales generado por la corrosión.

Dhaka has a population of about 19 million and many think it is a city of fortune. People come from all over the country to settle in Dhaka and many low-cost settlements (known as slums) have emerged since the country became independent. Findings of national survey reports suggest there is a high concentration of child labour in the slums of Dhaka, linked with the global supply chain of products. In order to understand the drivers of child labour in the slum areas of Dhaka, a research team formed of the Grambangla Unnayan Committee (GUC) with ChildHope UK designed and conducted a mapping and listing exercise, in consultation with CLARISSA consortium colleagues. The overall objective of the mapping and listing process was to identify and map children engaged in WFCL living in eight slum areas in Dhaka.
Efficacy of Short-Term High Dose Pulsed Dapsone Combination Therapy in the Treatment of Chronic Lyme Disease/Post-Treatment Lyme Disease Syndrome (PTLDS) and Associated Co-infections: A Report of Three Cases and Literature Review
Authors: Horowitz Richard I. , Freeman Phyllis R.
Published: May 2022

Lyme disease and associated co-infections are increasing worldwide and approximately 20% of individuals develop chronic Lyme disease (CLD)/Post-Treatment Lyme Disease Syndrome (PTLDS) despite early antibiotics. A 7–8-week protocol of double dose dapsone combination therapy (DDDCT) for CLD/PTLDS results in symptom remission in approximately 50% of patients for one year or longer, with published culture studies indicating higher doses of dapsone demonstrate efficacy against resistant biofilm forms of Borrelia burgdorferi. The purpose of this study was therefore to evaluate higher doses of dapsone in the treatment of resistant CLD/PTLDS and associated co-infections. Twenty-five patients with a history of Lyme and associated co-infections, most of whom had ongoing symptoms despite several courses of DDDCT, took one or more courses of high dose pulsed dapsone combination therapy (200 mg dapsone X 3-4 days and/or 200 mg BID x 4 days), depending on persistent symptoms. The majority of patients noticed sustained improvement in 8 major Lyme symptoms, including fatigue, pain, headaches, neuropathy, insomnia, cognition, and sweating, where dapsone dosage, not just treatment length, positively affected outcomes. High dose pulsed dapsone combination therapy may represent a novel therapeutic approach for the treatment of resistant CLD/PTLDS, and should be confirmed in randomized, controlled clinical trials.
Progress in Hexagonal Boron Nitride (h-BN) Based Solid State Neutron Detector

This article will briefly review the progress of h-BN based solid-state metal semiconductor metal (MSM) neutron detectors. In the last decade, several groups have been working on hexagonal boron nitride (h-BN) based solid-state neutron detectors. Recently, the detection efficiency of 59% has been reported. Efficient, low-cost neutron detectors made from readily available materials are essential for various applications. Neutron detectors are widely used to detect fissile materials and nuclear power plants for security applications. The most common and widely used neutron detectors are 3He based, which are sometimes bulky, difficult to transport, have high absorption length, need relatively high bias voltage (>1000 V), and have low Q-value (0.764 MeV). Also, 3He is not readily available material. Thus, there is a strong need to find an alternative detection material. 10B isotope has a high neutron absorption cross-section, and it has been tested as a coating on the semiconducting materials. Due to the two-step process, neutron capture through 10B, and then electron-hole pair generation in a typical semiconducting material, the efficiency of these devices is not up to the mark. The progress in h-BN based detectors requires a review to envision the further improvement in this technology.

Fusarium circinatum is an important global pathogen of pine trees. Genome plasticity has been observed in different isolates of the fungus, but no genome comparisons are available. To address this gap, we sequenced and assembled to chromosome level five isolates of F. circinatum. These genomes were analysed together with previously published genomes of F. circinatum isolates FSP34 and KS17. Multi-sample variant calling identified a total of 461683 micro variants (SNPs and small indels) and a total of 1828 macro structural variants of which 1717 were copy number variants and 111 were inversions. Variant density was higher on sub-telomeric regions of chromosomes. Variant annotation revealed that genes involved in transcription, transport, metabolism and transmembrane proteins were overrepresented in gene sets affected by high impact variants. A core genome representing genomic elements conserved in all the isolates and a non-redundant pangenome representing all genomic elements is presented. Whole genome alignments showed that an average of 93% of the genomic elements are present in all isolates. The results of this study reveal that some genomic elements are not conserved within the isolates and some variants are high impact. The described genome-scale variations will help inform novel disease management strategies against the pathogen.
Towards Ambient Intelligence-based Environments for Fall Detection and Indoor Localization: Methodology for a Simplistic Design for Real-World Implementation
Authors: Thakur Nirmalya , Han Chia Y.
Published: May 2022

Falls, highly common in the constantly increasing global aging population, can have a variety of negative effects on their health, well-being, and quality of life, including restricting their capabilities to conduct Activities of Daily Living (ADLs), which are crucial for one's sustenance. Timely assistance during falls is highly necessary, which involves tracking the indoor location of the elderly during their diverse navigational patterns associated with ADLs, to detect the precise location of a fall. With the decreasing caregiver population on a global scale, it is important that the future of intelligent living environments can detect falls during ADLs while being able to track the indoor location of the elderly in the real-world. Prior works in these fields have several limitations, such as – lack of real-world testing, lack of functionalities to detect both falls and indoor locations, high cost of implementation, complicated design, the requirement of multiple hardware components for deployment, and the necessity to develop new hardware or software for implementation, which make the wide-scale deployment of such technologies challenging. To address these challenges, this work proposes a simplistic design paradigm for the development of an ambient intelligence-based living environment with functionalities to perform indoor localization and fall detection during ADLs. The hardware necessary for the development of this system involves integration of easily available sensors, the combined cost of which is USD 262.15 – which upholds its cost-effectiveness. The results from real-world experiments that were performed uphold the effectiveness of the system design to capture multimodal components of the user interaction data during ADLs that are necessary for the detection of falls as well as indoor localization.

By 2020, over 100 countries expanded electric and plug-in hybrid electric vehicle (EV/PHEV) technologies, with global sales surpassing 7 million units. Governments are adopting cleaner vehicle technologies due to proven environmental and health implications of internal combustion engine vehicles (ICEVs), evidenced by the recent COP26 meeting. This article proposes an agent-based model of vehicle activity as a tool for quantifying energy consumption by simulating a fleet of EV/PHEVs within an urban street network at various spatio-temporal resolutions. Driver behaviour plays a significant role in fuel consumption, thus, simulating various levels of individual behaviour enhancing heterogeneity should provide more accurate results of potential energy demand in cities. The study found that 1) energy consumption is lowest when speed limit adherence increases (low variance in behaviour) and is highest when acceleration/deceleration patterns vary (high variance in behaviour) and 2) on average, for tested vehicles, EV/PHEVs were £116.33 cheaper to run than ICEVs across all experiment conditions. The difference in the average fuel costs (electricity and petrol) shrinks at the vehicle level as driver behaviour is less varied (more homogeneous). This research should allow policymakers to quantify the demand for energy and subsequent fuel costs in cities.
