Grid-connected inverters based on solar PV cells are becoming increasingly common. At times, the PV can be subjected to a certain environmental situation, such as varying irradiance or temperature. Present developments in gird-connected PV inverters do not have many reliable yields or reliability in this case. In this article, an improved control framework system is intended for two PV that are mismatched in various ways, resulting in a highly effective grid-connected solar inverter with THD under 1% for both voltage and current. The regulator employs a control scheme comprised of an ANFIS-based control system that works in tandem with the incremental conductance technique of MPPT. The outcomes are simulated and validated using MATLAB Simulink.

Published: October 2023

Vietnam's economy is developing strongly, and the demand for energy use will increase rapidly. The development of smart grids contributes significantly to the transition and sustainable development of energy from renewable energy sources to improve the quality of the national power supply and promote the sustainable use of electricity economically and efficiently. Thus, this is highly beneficial in reducing carbon emissions and other types of pollution. Besides, electrification in the transportation industry is developing rapidly, such as Electric Vehicles (EVs) and Metros in recent years. Integrating electric vehicles into the grid will enable two-way energy exchange, reactive power compensation and load balancing. However, the number of EVs participating in charging at a time will cause some conflicts, such as voltage and power loss at the nodes. Therefore, the balancing problem between load demand and generation source is a difficult task in planning operations. This paper presents a method to optimize island Microgrid (MG) operation with the participation of electric vehicles based on renewable energy sources. Optimization techniques in intelligent resource forecasting and management algorithms are built in MATLAB to achieve different requirements. The proposed Microgrid manages energy efficiency that adapts to the variability of Renewable Energy with improved efficiency.

Published: October 2023

At the outset of any project, every client’s primary goal is to attain value for their investment by securing a top-quality structure completed on schedule and within budget. Consequently, this study is devoted to the identification and prioritization of crucial risk factors that influence the choice of procurement methods in construction projects within the local government areas (LGA) of Nassarawa (NSR), Dala (DAL), and Kano Municipal (KMC) in Kano state. The methodology utilized entails surveying 146 participants, including both contractors and consultants. To assess the likelihood of these risks, the Relative Importance Index (RII) and the sign test were applied using Statistical Package for Social Science (SPSS) version 26. The results unveiled that factor associated with the client, project timeline, and cost exert the most profound influence on the choice of procurement method in the three LGA’s in Kano state. The most influential factors among these include the client’s financial capability, competition in pricing, constraints on project time, and procurement policies. In conclusion, a significant recommendation is for clients and consultants to enhance their procurement method oversight by involving skilled procurement specialists. This measure is essential for making informed choices, facilitating the attainment of a favourable return on investment, and guaranteeing the achievement of quality, timely, and budget-compliant project results.

Magnetic particle imaging (MPI) is a tracer imaging modality that detects superparamagnetic iron oxide nanoparticles (SPIOs), enabling sensitive, radiation-free imaging of cells and disease pathologies. The arbitrary waveform relaxometer (AWR) is an indispensable platform for developing magnetic nanoparticle tracers and evaluating tracer performance for magnetic particle imaging applications. One of the biggest challenges in arbitrary waveform excitation is direct feedthrough interference, which is usually six orders of magnitude larger than the signal from magnetic nanoparticles. This work will showcase hardware that suppresses this interference by an order of magnitude, increasing the dynamic range of the instrument and enabling mass-limited detection at full scale range.

Online Graph Learning Via Proximal Newton Method From Streaming Data

Published: October 2023

Learning graph topology online with dynamic dependencies is a challenging problem.  Most existing techniques usually assume the generative model to be a diffusion process instigated by a graph shift operator (GSO) and that a first-order method,  such as proximal gradient or least-mean-square (LMS), are used to track the graph topology.  However, they are often susceptible to noisy observations and does not perform well against second-order methods.  This work proposed two forward-backward splitting algorithms called the proximal Newton-iterated extended Kalman filter (PN-IEKF) and PN-IEKF-vector autoregressive (PN-IEKF-VAR) algorithms to track non-causal and causal graph topology with dynamic dependencies, respectively.  The proposed methods directly maximize the posterior probability distribution of the observable graph signal and graph matrix, which make our PN-IEKF framework to be more robust toward additive white Gaussian noise.  The two methods can directly handle streaming data which process them as they become available.  Effectiveness of the proposed methods can be further improved by including a $T$-squared detector in the tracking procedure, which helps to inject proper perturbation to the latent dynamic model such that the time-varying nonstationary graph can be reacquired faster amid abrupt changes in the underlying system. Results on relative error and normalized mean square error using synthetic data on Erd\fH{o}s-R\'enyi graph establish the efficacy of the proposed approach. Simulation results using data from the Dataset for Emotion Analysis Using EEG, Physiological and Video Signals (DEAP) and National Oceanic and Atmospheric Administration (NOAA) are encouraging. Computational and time complexity analysis of the proposed algorithm are given and compared with other algorithms.

Bi-pass Formulation for Non-conforming Meshes in Magnetostatic Problems
Authors: Houssein Houssam
Published: October 2023

In this paper, a method to solve magnetostatic problems for
non-conforming meshes using penalty method is presented, where the
interface conditions are imposed at the integration points. In the case
of non-conforming meshes, there are two interfaces at the contact of the
two bodies, so in order to impose the interface conditions, which
connect the two bodies involved, the interface conditions must be
expressed with respect to one interface, in this case I call slave, the
body containing this interface and the other the master one. The best
choice of the slave body, in order to obtain the most accurate solution,
is investigated in this paper. Furthermore, this paper introduces a
novel formulation known as the bi-pass or symmetric formulation, where
each body is taken simultaneously as slave and as master, so there is no
need to make the best choice of the slave body which in some situations
is difficult to do. Additionally, this formulation leads to more
accurate solutions

The History of Africa in International Relations (HAIR) put at the disposal of Post-Graduate Students and other readers is well intensive using scrutinized research work of the specialization to make an in-depth understanding of the happenings since the second half of the 20th Century and what is occurring in the 21st Century with new leaders cropping up with more pragmatic ideologies of chasing out neo-colonialist for the benefit of their specific countries. This situation is very welcoming in West African countries with specific strategic of using military coup d’états to flush out puppet Western leaders in the names of Head of States. The cases of Mali, Burkina Faso, and Niger among others caught our attention more recently. Our inspirations are drawn from published scientific works, documentaries, related books and specialized websites consulted online following the recent occurring with specific focus concerning Burkina-Faso where on September 30, 2022 a military coup took place in Burkina Faso. As a result, Lieutenant Colonel Paul-Henri Sandaogo Damiba was overthrown and Captain Ibrahim Traoré replaced him in power. The constitution was suspended, state institutions were dissolved, borders were closed and the army imposed a curfew throughout the country thereby urging the Departure and end of French neo-colonialism with cancellation of specific accords of cooperation signed at independence This research is very interesting to students specializing in International Relations (IR) especially Africa in HAIR. However, a historical method was deem necessary with statistical tables giving some important representations and commercial exchanges between Burkina Faso and France barely a year before the cropping of conflicting bilateral relations since 2022.Our experiences from lecturing IR and HAIR with specific questions frequently asked by Post-Graduates students is among the motivated factors thereby highlighting issues which can be more valuable to other ..........

Published: October 2023

The state of affairs over the years since Nigeria assumed the practice of democracy has been largely anti-democratic in practice, this scenario has led to an outcome of impoverishment, stagnation and the torn-stunk of the living conditions of the proletariats, which have undermined their faith and confidence in the electoral outcome and governance in Nigeria. The chunks of the Nigerian masses which represent the proletariats in Nigeria have been the most deleteriously affected group of the population in Nigeria. In view of the above, this paper examined the impact and implication of the proletariat’s rendezvous in the 2023 general elections in Nigeria. The paper adopted the qualitative research method, while utilizing textbooks, journals, newspapers, government publications, rules of proceedings and internet materials. Also applied was the Rational Choice Theory as propounded by Adam Smith in 1770 as its theoretical framework of analysis to provide understanding, explanation and as well make predictions germane to the problematic. The paper find out and concludes that the 2023 general election in Nigeria fell short of the credibility threshold set. Based on the findings, recommendations were made that additional reforms and improvements are required to ensure that the quality of future elections in Nigeria does not further decline, and that public confidence in the capacity of INEC to conduct elections is restored, while trust in the credibility of elections is re-established.

Published: October 2023

Land Surface Temperature  (LST) adalah fenomena peningkatan suhu permukaan tanah yang lebih tinggi dibandingkan dengan suhu rata-rata di sekitarnya. Salah satu penyebab peningkatan LST adalah perubahan pola tutupan lahan. Penelitian ini dilakukan untuk mengetahui korelasi Normalized Difference Vegetation Index (NDVI) terhadap LST di Kabupaten Pasuruan. Penelitian ini dilakukan dengan cara mengunduh data dari citra satelit landsat pada website climate change tahun 2001 dan 2020, kemudian diolah menggunakan QGIS, dan dilakukan uji korelasi menggunakan microsoft excel. Kabupaten Pasuruan dipilih menjadi wilayah studi dalam penelitian ini, karena  Kabupaten Pasuruan mengalami peningkatan suhu sebesar 2,050 Celcius dari tahun 2001 ke tahun 2022. Hasil yang diperoleh dari uji korelasi NDVI dan LST adalah -0,56 pada tahun 2001, yang berarti LST dan NDVI memiliki korelasi yang cukup kuat, namun korelasinya berhubungan terbalik. Hubungan terbalik menunjukkan jika kerapatan vegetasi yang rendah, maka suhu permukaan tanah akan naik dan berlaku sebaliknya. Korelasi pada tahun 2022 adalah -0,62 yang menunjukkan adanya peningkatan korelasi.

Published: October 2023

O edentulismo é um importante problema de saúde pública que acarreta inúmeras sequelas e reduz de modo significativo a qualidade de vida do paciente, tanto em termos funcionais quanto estéticos. Perdas dentárias do arco superior podem ser acompanhadas de atrofia da maxila, o que dificulta o processo de reabilitação, uma vez que impede a realização de procedimentos que.boa quantidade de massa óssea local. O presente estudo é uma revisão de literatura narrativa que visa descrever o uso da técnica all-on-4 na reabilitação de maxila atrófica em pacientes edêntulos. Assim, uma das abordagens para melhor reabilitação da maxila atrófica desdentada é a técnica all-on-4, procedimento cirúrgico que utiliza quatro implantes para ancoragem de prótese total do arco superior ou inferior. A angulação adequada dos implantes durante a técnica resulta em maior superfície para ancoragem da prótese fixa, que apresenta grande estabilidade e ótimo padrão estético. Trata-se de um procedimento minimamente invasivo e de custo relativamente reduzido que traz resultados satisfatórios na maioria dos casos de edentulismo com atrofia maxilar, com vantagens que incluem previsibilidade, menor tempo de execução do procedimento, redução do cantiléver posterior e elevada estabilidade biomecânica, além do custo reduzido e menor tempo de recuperação.  Porém, trata-se de um método de difícil execução que requer bom planejamento e elaboração pré-cirúrgica, além de ser contraindicado em casos de discrasias hematológicas, diabetes, imunossupressão e doenças crônicas. Sua realização é feita em etapas que envolvem seleção do caso; análise da viabilidade de aplicação do protocolo; planejamento do caso; escolha dos locais dos implantes; colocação dos implantes e, por fim, a fase protética. Na grande maioria dos casos os sinais inflamatórios pós-procedimento são reduzidos e a sobrevida dos implantes é longa. Dessa forma, pode-se concluir que a reabilitação de edentulismo com maxila atrófica pela técnica all-on 4 é uma abordagem efetiva que permite que o paciente edêntulo possa recuperar tanto as funções de mastigação, deglutição e fala, como também melhorar o aspecto estético da face.

Prevalência de sintomas musculoesqueléticos e fadiga em pilotos instrutores de T-27 da Força Aérea Brasileira e fatores associados
Authors: Duque Eduardo , Massaferri Renato , Calvo Adriano
Published: October 2023

Introdução: Os pilotos instrutores de T-27 da Academia da Força Aérea (AFA) são constantemente expostos a uma grande quantidade de voos, frequentemente com cargas G elevadas, aumentando o risco de sintomas musculoesqueléticos (SME) e fadiga após voo (FAV). Aponta-se que a prática de exercício físico regular (EFR), principalmente em volumes altos, pode diminuir a prevalência destes sintomas. Entretanto, dados que os relacionam com EFR são limitados.
Objetivo: Avaliar a associação de perfil de EFR e FAV com SME em pilotos instrutores de T-27 da Força Aérea Brasileira (FAB).
Métodos: Foram selecionados para a pesquisa 50 instrutores, que preencheram um questionário sobre experiência de voo, prática de EFR, SME e FAV. Para comparações entre grupos foi utilizado o teste Exato de Fisher (p<0,05).
Resultados: Setenta e oito por cento dos instrutores reportaram SME, destacando-se a região lombar (60%). FAV alta foi reportada por 42% após voo acrobático, 14% após dois voos e aumento para 68% após o terceiro voo diário. Não foram encontradas diferenças no acometimento de SME e FAV quando praticado EFR, independentemente do volume. Encontrou-se associação entre FAV na lombar após voo acrobático e presença de SME frequentes, além de efeito mais intenso quando o SME é específico na lombar.
Conclusão: A prevalência de SME e FAV nesta população é alta, sendo a região lombar a mais afetada. Os sintomas agravam-se com o acúmulo de voos e com os voos acrobáticos. A prática de EFR, independentemente do volume, parece não influenciar, sugerindo que o treinamento físico realizado pode não ser o mais adequado.

Authors: De Oliveira Alison S , Costa e Silva Gabriel , Nogueira Francine Caetano de Andrade , Salgado Filho Leandro Nogueira
Published: October 2023

Introdução: Durante a pandemia, apesar da ausência de fundamentação científica, os exercícios ao ar livre, em academias e outros espaços foram contraindicados e proibidos. Contudo, em meio ao decurso pandêmico houve um momento inflexivo destas recomendações, antes mesmo do início da vacinação.
Objetivo: Analisar ações políticas adotadas em saúde durante a pandemia de CoViD-19 e identificar o momento da inflexão que demarcou o resgate das razões para retorno do reconhecimento da prática mais ampla dos exercícios físicos como estratégia em medicina preventiva.
Métodos: Realizou-se uma pesquisa exploratória, analisando e sintetizando evidências científicas atualizadas.
Resultados: O fim do negativismo contra a prática dos exercícios ao ar livre, em academias e demais espaços como estratégia coadjuvante para enfrentamento da CoViD-19, teve início entre julho e agosto de 2020, aproximadamente.
Conclusão: A prática de atividades e exercícios físicos constitui-se em medida protetiva à saúde que, durante o período da pandemia de CoViD-19, em razão das decisões políticas adotadas comprovaram-se como inadequadas para conter o avanço do coronavírus face às evidências científicas referentes à relação exercício físico – imunologia.

The productivity management of oil palm plantations is carried out by analyzing various influencing factors, but the growing conditions of oil palms are one of the causes of fluctuations in oil palm production. This paper aims to identify post-harvest increases in oil palm productivity. Productivity depends on the number of clusters and the weight of fresh fruit bunches (FFB) produced yearly. The methods of this study were conducted using a targeted sampling technique using available production data for plant time points from 4 to 13 years of age. The total plant sample was 636 ha in Central Kalimantan. As a result, plant growth factors can significantly impact oil palm productivity as measured by the components of oil palm plant production: fresh bunch production per hectare, average bunch weight, and the number of oil palm bunches. FFB tonnage and mean bunch weight increase each year from age 3 to age 13, according to a quadratic regression pattern, whereas the number of palm clusters, in contrast, decreases in number with increasing plant age. This study was intended to serve as a reference and source of information for making production decisions for oil palm plantations to achieve optimal results.

Халықты азық-түлікпен қамтамасыз ету мақсатында ауылшаруашылық айналымнан шығып қалған «тыңайған жерлерді» қайта игеру өте маңызды. Қазақстанның оңтүстігінде егістік жерлердің ауылшаруашылық айналымнан шығып қалуы – бірінші кезекте тұзданумен тығыз байланысты. Тұрақты даму мақсатында олардың қазіргі жағдайын зерттеу, тұзданған топырақтарды мелиорациялауға арналған әлемдік зерттеулерге шолу жасау арқылы қайта игеруге  ұсыныстар әзірлеудің қажеттілігі туындап отыр. Сондықтан, осы зерттеуіміз Оңтүстік Қазақстандағы Отырар ауданының мысалында тыңайған жерлердің қазіргі экологиялық-мелиоративтік жағдайын зерттеу және оларды игеру мәселелерін талқылау және ұсыныстар келтіруге арналды. Зерттеу барысында тыңайған жерлердің пайда болуы мен қалыптасуын зерттеуде тарихи әдісті, зерттеу нысанына аумақтық талдау жасау жұмыстары кезінде географиялық талдау әдісі, мәселелердің күрделілігі мен интенсивтілігін көрсетуде статистикалық және салыстыру әдістерін, зерттеу нысанындағы тыңайған жерлердің ахуалын  зерттеуде картографиялық және геоақпараттық әдістерді, тыңайған жерлердің контурларын тексеруде далалық зерттеу (рекогноцсировтық) және зерттеу тақырыбы бойынша ғылыми мәліметтермен жұмыста топтастыру және талдау әдістері қолданылды. Геоақпараттық технологиялардың көмегімен зерттеу нысанындағы тыңайған жерлердің көлемі – 13688,9 га, оның ішінде тұзданбаған топырақтар тараған жерлердің көлемі – 83,9 га, шамалы тұзданған топырақтар – 984,4 га, орташа тұзданған топырақтар – 2398,3 га, қатты тұзданған топырақтар – 10222,1 га құрайтыны анықталды. Тұзданған жерлерді игеру мен мелиорациялаудың бойынша ғалымдар ұсынған әдіс-тәсілдер мен технологияларға шолу жасалды. Зерттеу нысанының экологиялық-мелиоративтік жағдайы мен шаруа қожалықтарының материалдық-техникалық мүмкіндіктерін ескере отырып, тыңайған жерлерді игерудің 2 әдісі (органикалық және агроинновациялық) ұсынылып, топырақтардың тұздану жағдайында оларды қолданудың қажеттілігі ғылыми негізделді.

Бурая ржавчина, вызываемая паразитическим базидиальным грибом Puccinia recondita f.sp. tritici, одно из наиболее вредоносных заболеваний яровой мягкой пшеницы как в Казахстане, так и в мире. Развитие ржавчиных болезней может приводить  к значительному снижению  урожайности  восприимчивых сортов  пшеницы. Основной проблемой селекции пшеницы является потеря эффективности генов устойчивости, что обусловлено появлением новых вирулентных рас патогенов. В данной статье представлены результаты оценки устойчивости сортов яровой мягкой пшеницы на стадии проростков и взрослого растения, а также результаты скрининга Lr генов устойчивости с помощью молекулярных маркеров. В результате проведенных опытов было отобрано 9 образцов, демонстрирующих высокий уровень устойчивости к обоим расам P. recondita – MKT/Q и TJT/R на стадии проростков. В полевых условиях за два года испытаний было отобрано 6 сортов, проявивших высокий уровень устойчивости к возбудителю. Использование молекулярных маркеров позволило идентифицировать носителей эффективных Lr генов устойчивости. По результатам молекулярного скрининга определено 4 носителя гена устойчивости Lr9; 5 носителей гена Lr10; 7 носителей Lr26; 7 носителей Lr34 и 2 носителя гена Lr46. Полученные результаты могут быть использованы в селекционных программах Казахстана.

Из-за изменения климата, в последние годы, среднесуточные температуры атмосферного воздуха значительно повысились в весенние и летние месяцы, и прогнозы указывают на их дальнейшее повышение. При этом, повышение температуры тела животных вызывает изменения на клеточном и системном уровне, которые снижают интенсивность метаболических и производственных процессов, связанных с выделением тепла, в краткосрочной и долгосрочной перспективе (гомеоретическая адаптация).        Исселованиями зарубежных ученых доказано, что затраты на охлаждение в летней и отопление зимней периоды года животноводческих помещений, как правило, значительно ниже, чем потери вызываемые множеством негативных последствий с точки зрения физиологических и поведенческих нарушений и значительных потерь в производстве продуктивности молока и перерасхода кормов. Поэтому создание систему, которая обеспечит оптимальные условия для улучшения содержания крупного рогатого скота (КРС) с минимальными  энергозатратами в   технологических процессах формирования нормативного микроклимата в животноводческих помещениях, является актуальной.
В статье рассматривается вариант формирования микроклимата в животноводческих помещениях в условиях выращивания КРС в малых и средних крестьянских и фермерских хозяйствах республики. Предлагаемая конструкция системы охлаждение и отопления сельскохозяйственных объектов, снижает тепловую мощность и расход электроэнергии на создание нормированного микроклимата в животноводческих помещениях благодаря повышения эффективности применения системы реверсивного теплового насоса чиллера-фэнкойла, интегрированной возобновляемыми источниками энергий, которая обеспечить требуемый технологический эффект минимальными энергозатратами.
