Published: July 2024

Abstract: The Nigerian electric power industry, pivotal for economic development, faces severe crises affecting its efficiency. This study provides a comparative analysis of electricity grid tariffs and generator costs over the past decade. The analysis reveals frequent tariff changes by the Nigerian Electricity Regulatory Commission (NERC) and rising generator costs due to increasing fuel prices and maintenance expenses. The study highlights the financial burden on Nigerian households and businesses reliant on generators. Data from NERC reports, Nigerian National Petroleum Corporation (NNPC) fuel price records, and industry studies indicate that generator costs have escalated more sharply. At the same time, grid tariffs have increased due to economic and policy changes. This disparity stresses the need for policy adjustments and improved monitoring to stabilise electricity costs and enhance service delivery. Recommendations urge immediate action from policymakers, energy industry professionals, and stakeholders to address the pressing issues.

Este estudo analisou o impacto das tecnologias emergentes na educação, destacando suas vantagens, desafios e possíveis futuros desenvolvimentos. O objetivo principal é compreender como essas tecnologias podem ser eficazmente integradas no design instrucional. A metodologia empregada incluiu uma revisão sistemática da literatura, abrangendo artigos empíricos, revisões. Os resultados indicam que tecnologias como inteligência artificial, realidade aumentada e impressão 3D têm potencial para personalizar o ensino, aumentar o engajamento dos alunos e melhorar a compreensão de conceitos complexos. Contudo, a implementação enfrenta desafios significativos, como infraestrutura inadequada, falta de capacitação dos professores e preocupações com a privacidade dos dados. A pesquisa revela que a impressão 3D facilita a visualização de conceitos complexos (Fagundes, 1993), enquanto a realidade aumentada enriquece a experiência de aprendizagem (Moran, 2004). A inteligência artificial adapta o conteúdo às necessidades individuais dos alunos, proporcionando feedback imediato e promovendo uma aprendizagem mais eficaz (Rocha, 2009). No entanto, é essencial investir em infraestrutura tecnológica robusta, programas de desenvolvimento profissional contínuo para educadores e políticas claras de proteção de dados para superar os desafios. Exemplos práticos, como plataformas adaptativas de aprendizagem e simuladores virtuais, demonstram a eficácia dessas tecnologias na personalização do aprendizado e preparação dos alunos para os desafios do século XXI (Bergmann; Sans, 2015). Em conclusão, as tecnologias emergentes têm o potencial de revolucionar a educação. A exploração contínua dessas tecnologias e a colaboração entre educadores, pesquisadores e a indústria de tecnologia são fundamentais para criar um ambiente educacional inclusivo, equitativo e eficaz.

A Doença Ulcerosa Péptica é uma condição crônica e recorrente que afeta a mucosa do trato gastrointestinal superior, manifestando-se principalmente no estômago e no duodeno. Esta patologia resulta de um desequilíbrio entre os fatores agressivos, como a infecção pelo Helicobacter pylori  e o uso de anti-inflamatórios não esteroides, e os mecanismos de defesa da mucosa. A Doença Ulcerosa Péptica é prevalente em 5 a 10% da população global, com uma incidência anual de 0,1 a 0,3%. Apesar da redução nas taxas de incidência, hospitalizações e mortalidade nas últimas décadas devido aos avanços no diagnóstico e tratamento, a doença ulcerosa péptica continua sendo uma importante preocupação de saúde pública, associada a complicações graves, como hemorragias e perfurações, que podem levar à hospitalização e aumento dos custos médicos. As manifestações clínicas da Doença Ulcerosa Péptica incluem dor epigástrica, dispepsia, náuseas e vômitos, sendo a confirmação diagnóstica realizada principalmente através da endoscopia digestiva alta. O tratamento envolve o uso de inibidores da bomba de prótons e a erradicação do H. pylori. Este artigo revisa os principais fatores de risco, complicações e abordagens de tratamento da úlcera péptica, baseando-se em uma análise de estudos científicos relevantes.

Abstract. Aerosol particles play critical roles in climate and human health. However, aerosol composition and evolution, particularly secondary organic aerosol (SOA), and aerosol interactions with clouds in high-altitude background areas in China remain less understood. Here, we conducted real-time measurements of submicron aerosols (PM1) using aerosol mass spectrometers at a forested mountain site (1128 m a.s.l.) in southeastern China in November 2022. The average (±1σ) PM1 mass concentration was 4.3±4.8 µg m−3, which was ubiquitously lower than that at other mountain sites in China. Organic aerosol (OA) constituted the largest fraction of PM1 (42.9 %) and was predominantly secondary, as indicated by the high oxygen-to-carbon (O / C) ratio (0.85–0.96) and carbon oxidation state (0.21–0.49). Notably, the remarkably enhanced PM1 concentrations observed during the daytime on cloudless days were identified to be likely to be produced from cloud evaporation. While more oxidized oxygenated OA was scavenged efficiently during cloud events, cloud evaporation was found to release a significant amount of less oxidized oxygenated OA from air masses transported from polluted regions. The distinct decrease in OA / ΔCO with the increase in O / C during the cloud evaporative period further demonstrates that OA remaining in cloud droplets is generally in a moderate oxidation state. Moreover, organic nitrates were also estimated and showed a higher contribution to the total nitrate during the cloudy period (27 %) than during the evaporative period (3 %). Overall, our results demonstrate the importance of SOA and the influences of cloud processes in regional mountain areas in southeastern China.
Chaotic oceanic excitation of low-frequency polar motion variability

Published: July 2024

Abstract. Studies of Earth rotation variations generally assume that changes in non-tidal oceanic angular momentum (OAM) manifest the ocean's direct response to atmospheric forces. However, fluctuations in OAM may also arise from chaotic intrinsic ocean processes that originate in local nonlinear (e.g., mesoscale) dynamics and can map into motions and mass variations at basin scales. To examine whether such random mass redistributions effectively excite polar motion, we compute monthly OAM anomalies from a 50-member ensemble of eddy-permitting global ocean/sea-ice simulations that sample intrinsic variability through a perturbation approach on model initial conditions. The resulting OAM (i.e., excitation) functions, χ̂O, are examined for their spread, spectral content, and role in the polar motion excitation budget from 1995 to 2015. We find that intrinsic χ̂O signals are comparable in magnitude to the forced component at all resolved periods except the seasonal band, amounting to ∼46 % of the total oceanic excitation (in terms of standard deviation) on interannual time scales. More than half of the variance in the intrinsic mass term contribution to χ̂O is associated with a single, global mode of random bottom pressure variability, likely generated by nonlinear dynamics in the Drake Passage. Comparisons of observed interannual polar motion excitation against the sum of known surficial mass redistribution effects are sensitive to the representation of intrinsic χ̂O signals: Reductions in the observed excitation variance can be as high as 68 %, or as low as 50 % depending on the choice of the ensemble member. Chaotic oceanic excitation thus emerges as a new factor to consider when interpreting low-frequency polar motion changes in terms of core-mantle interactions or employing forward-modeled OAM estimates for Earth rotation predictions.
Comparative Analysis of μ (I) and Voellmy-Type Grain Flow Rheologies in Geophysical Mass Flows: Insights from Theoretical and Real Case Studies
Authors: Zhuang Yu , McArdell Brian W. , Bartelt Perry
Published: July 2024

Abstract. The experimental-based μ(I) rheology is now prevalent to describe the movement of gravitational mass flows. Here, we reformulate μ(I) rheology as a Voellmy-type relationship to illustrate its physical implications. Through one-dimensional block modeling and a real case study, we explore the equivalence between μ(I) and widely-used Voellmy-type grain flow rheologies. Results indicate that μ(I) rheology utilizes a dimensionless inertial number to mimic contributions of granular temperature/fluctuation energy. In terms of Voellmy, the μ(I) rheolgy contains a velocity-dependent turbulent friction coefficient modelling shear thinning behavior. This turbulent friction assumes the production and decay of fluctuation energy are in balance, exhibiting no difference during accelerative and dipositional phases. The constant Coulomb friction coefficient prevents μ(I) rheology from accurately modeling the dispositional characteristics of actual mass flows. Our results highlight the strengths and limitations of both μ(I) and Voellmy rheologies, bolstering the theoretical foundation of mass flow modeling while revealing practical engineering challenges.

Abstract. This study reconstructs recent changes (1880–2017) in sea-ice conditions, using biomarkers (IP25 and phytoplankton sterols) from three sediment cores located in a transect across Belgica Trough, on the Northeast Greenland continental shelf. These results are evaluated using instrumental and historical data from the same region and time period. Over the entire study period, IP25 concentrations are highest at the inner shelf (site 90R) and decrease towards the mid-shelf (site 109R), with lowest values found at the outer shelf (site 134R). The PIP25 index yields the highest sea-ice cover at sites 109R and 90R and the lowest at 134R, in agreement with observational records. A decline in sea-ice concentration, identified visually and using change-point analysis, occurs from 1971 in the observational sea-ice data at sites 90R and 109R. A change in sea-ice concentration occurs in 1984 at site 134R. Sea-ice conditions in these years aligns with an increase in sterol biomarkers and IP25 at all three sites and a decline in the PIP25 index at sites 90R and 134R. The outcomes of this study support the reliability of biomarkers for sea-ice reconstructions in this region.
Digital Governance and Neoliberalism: The Evolution of Machine Learning in Australian Public Policy
Authors: Jobberns Harry , Guihot Michael
Published: July 2024

Increasingly, government agencies are using computers to automate decisions about citizens. Often, the reason proffered for this is increased efficiency. This article reveals the extent to which computer automated decision-making processes in government are being legislatively adopted, provides an overview of the risks associated with such incorporation and analyses the limited extent to which the parliament has considered these associated risks. We analysed 35 core pieces of Commonwealth legislation that allow computers to make decisions on behalf of the administrative decision-maker. The Commonwealth government has authorised at least 35 of its agencies to use computers to make decisions and in doing so has expanded its power. This has occurred without much debate. We reviewed the associated secondary materials – including second reading speeches and parliamentary debates – to understand the level of discussion on the issue. Surprisingly, our analysis reveals that most amendments have passed with little to no debate. While the drive for governmental efficiency is commendable, failing to adequately debate the risks involved in automating administrative decisions undermines core administrative law principles and exposes governmental agencies and, more importantly, the Australian population to the risk of serious error. This article calls for increased debate before these authorisations are made and the incorporation of audit and review processes to control the use of this power by government agencies ex post.
Using a Hyper-Flexible Online Teaching Approach: A Mixed-Methods Evaluation
Authors: Brabin Jodie , Jakimowicz Samantha
Published: July 2024

In higher education the COVID-19 pandemic has accelerated a shift to online learning. Despite its uncommon practice in universities, designing courses with both flexible delivery and assessments has demonstrated enhanced understanding and improved application to professional contexts, particularly benefiting older students working full-time and managing caregiving responsibilities. Using a mixed methods approach, combining qualitative and quantitative feedback through student surveys and learning management system data, this study reveals that a hyper-flexible approach effectively accommodates students, particularly those with conflicting family and professional commitments. While peer-to-peer engagement was reported to be negatively affected, students perceive this as an acceptable trade-off to flexible learning. Although not universally applicable, hyper-flexible teaching proves highly beneficial for non-traditional students with professional and personal obligations, fostering a positive learning environment conducive to deeper understanding.

Published: July 2024

Next-generation mobility, particularly automated vehicles (AVs), has made significant progress towards public road integration, promising safer and more effective transportation. However, current prototypes must integrate intentions and social interactions within the motion prediction (MP) framework. This thesis addresses these challenges through three key studies: Study 1 establishes a comprehensive methodological framework for MP with a novel categorisation of MP methods; Study 2 develops a deep learning algorithms for vehicle behaviour prediction; Study 3 proposes a graph-based trajectory prediction. These contributions enhance the understanding of social interaction and intention forecasting, optimising AV technology for safer and sustainable transportation.

В статье излагается актуальность рассматриваемого вопроса, обосновываются методы его решения.  Для исследования и моделирования процессов пляски проводов и гололедообразования на проводах необходимо иметь сведения о крутильной жесткости, так как, крутильная жесткость провода зависит от  материала и конструкции, диаметра, длины пролета, натяжения. Аналитическое определение крутильной жесткости проводов с учетом всех этих факторов не представляется возможным. Поэтому, оценка крутильной жесткости во многом осуществляется экспериментально. В основе эксперимента лежит определение зависимости между крутящим  моментом и углом закручивания одиночных проводов. Опираясь на эти данные, крутильная жесткость определяется косвенно, то есть путем вычисления.  Такой способ оценки жесткости создает некоторые неудобства.  Поэтому в статье ставится задача оценки крутильной жесткости непосредственно – через диаметр провода.  На основе обработки экспериментальных данных в статье получена эмпирическая формула, которая позволяет оценить крутильную жесткость провода по его диаметру.  Достоверность формулы проверена путем составления эмпирической и экспериментальной зависимости.  Расчетная формула для оценки крутильной жесткости одиночных сталеалюминевых проводов используется при решении различных прикладных задач.

В работе представлены результаты сравнительного анализа лабораторных проб угля марки СС, подготовленных в условиях инертной атмосферы (азот) и стандартными методами в воздушной среде. Для характеристики изменения поверхности угольных частиц использовали ИК-спектральный и химический анализы функциональных кислородных групп. Оценку смачивающих свойств угля осуществляли с использованием ряда взаимодополняющих методов – определение краевого угла смачивания по капле жидкости, фильтрация жидкости через слой угольного порошка и реагентная флотация. Показано, что взаимодействие угольной поверхности с кислородом воздуха в условиях пробоподготовки оказывает ощутимое влияние на изменение функционального состава и, как следствие, естественной гидрофобности угольных частиц. Полученные результаты могут быть использованы для уточнения оценки свойств нативных пластовых углей, совершенствования технологий подготовки угольных проб, обогащения и переработки углей.

The paper presents the results of a comparative analysis of laboratory samples of SS grade coal prepared in an inert atmosphere (nitrogen) and standard methods in the air. IR spectral and chemical analysis of functional acid groups were used to characterize changes in the surface of coal particles. The wetting properties of coal were evaluated using a number of complementary methods – determination of the wetting edge angle by a drop of liquid, filtration of liquid through a layer of coal powder and reagent flotation. It is shown that the interaction of the coal surface with air oxygen under sample preparation conditions has a noticeable effect on the change in the functional composition and, as a consequence, the natural hydrophobicity of coal particles. The obtained results can be used to refine the assessment of the properties of native formation coals, improve the technologies of coal sample preparation, coal enrichment and processing.

Published: July 2024

The problems with bone healing still exist, despite the significant development of treatment methods in traumatology and orthopedics. There is a standard treatment approach with expected consolidation times of up to 6 months for diaphyseal femoral fractures. However, there are no algorithms for cases when the time for consolidation exceeds 1 year. In this article is presented the experience of treating a patient with a diaphyseal femoral fracture that had delayed consolidation.

OBJECTIVE: This study systematically reviewed and meta-analyzed the differential attrition and utilization of occupational mental health interventions, specifically examining delivery methods (internet-based versus in-person).

METHODS: The research, with papers spanning 2010–2024, involved filtering criteria and comprehensive searches across PubMed, Scopus, and Web of Science Core (PROSPERO registration n. CRD42022322394). Of 28 683 titles, 84 records were included in the systematic review, with 75 in meta-analyses. Risk of bias was assessed through the revised Cochrane risk of bias tool for randomized control trials and funnel plots. Differential attrition across studies was meta-analysed through a random-effects model with limited maximum-likelihood estimation for the degree of heterogeneity.

RESULTS: Findings reveal higher mean differential attrition in the intervention group, indicating a potential challenge in maintaining participant engagement. The attrition rates were not significantly influenced by the mode of intervention delivery (internet versus in-person). Compensation for participation and year of publication could potentially influence differential attrition from baseline to follow-up measurements.

CONCLUSIONS: These results suggest a need for cautious consideration of attrition in occupational mental health intervention study designs and emphasize the importance of adapting statistical analyses to mitigate potential bias arising from differential attrition.

Persistent venous hypertension is a pathological condition occurring in chronic venous insufficiency (CVI), as a consequence of venous reflux and/or obstruction and calf muscle pump function failure. The main non-invasive treatment options for improving venous functions and hemodynamics are compression and rehabilitation program of physical activities and modalities. Elastic taping (ET) is one of therapy modality aimed to assist muscle function, increasing lymphatic and vascular flow, correction of joint problems and activation of sensory system. The objective of this study was to assess the eff1ect of ET applications of lateral gastrocnemius (LG), medial gastrocnemius (MG) and tibialis anterior (TA) muscles on it muscles activities and venous reflux after 4 days of application. This is a matched control pre-post study with consecutive sampling. A twenty lower limbs from 10 women with bilateral mild CVI were randomized into control and intervention group. The subjects of each group underwent initial and 4 days after intervention measurement of maximal amplitude of GL, GM, and TA muscles during active contraction and ambulation using surface electromyography (sEMG). Venous reflux of femoral (FV) and popliteal (PV) veins were evaluate using duplex ultrasonography. This study was analyzed with Wilcoxon signed ranks test and Mann-Whitney test. Significant increase of maximal amplitude of the GL and TA muscles during active contraction, also GM muscle during ambulation after 4 days of ET application within intervention group. Significant decrease in the duration of PV reflux after 4 days of ET application within intervention group. Significant difference in the duration of PV reflux when compared to the control group. The conclusions are ET applications of the calf muscle pump system in patient with mild CVI may have an effect of increased muscle activity during active contractions and ambulation expressed as maximum amplitude in sEMG, and also decrease the duration of PV reflux.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) caused pandemic with a rapid spread and became a major public health issue in the world in year 2020. A potentially lethal illness known as coronavirus disease-2019 was produced by this novel coronavirus member (COVID-19). Combatingthe COVID-19/SARS-CoV2 epidemic, which is endangering the foundation of our civilization, resulting in horrific human casualties, and placing a massive economic burden on the whole world, has presented us with an unparalleled task. The creation of novel testing kits and treatment stoco mbatthe pandemic, including the creation of portable, quicklydeployable, and cost-effective diagnostic testing kits, personal protective equipment, mechanical ventilators, vaccines, and data analysis and modelling tools, has become urgently necessary during this trying time. The vaccination of the populace is acknowledged as a public health priority in the current setting of the epidemic caused by SARS-COV-2. The genomic sequencing for SARS-COV2 was completed fast, in just one month. Since then, vaccination has been the focus of research on a global scale. The pandemic has compelled scientists across the globe to research solutions for treatments as well as vaccines to stop COVID-19. Various researches on SARS-CoV and, to a lesser degree, MERS have provided guidance about immunisation tactics regarding this unique coronavirus. It is explained by the statement that the SARS-CoV-2 shares 79% genetic similarity with SARS-CoV and uses human Angiotensin Converting Enzyme 2 (hACE2) receptor on the host cell. There are several platforms for developing vaccines, including virus-vectored vaccines, m-RNA based vaccines, protein subunit vaccines, m-RNA based nanotherapeutics, intranasal vaccines, recombinant spike protein vaccines, self-amplifying m-RNA vaccines and monoclonal antibodies for passive immunisation that are being evaluated for COVID-19. All these platforms have certain pros and cons. The COVID-19 pandemic is possibly the second most deadly in the last century after the Spanish flu that requires a quick assessment of the various target efficacies in inducing immunity in preventing unplanned immune-potentiation. This article aims to give readers a detailed insight intovaccines that will be successful against the new coronavirus that has ravaged the global economy, human health, and quality of life.
