Published: July 2024

в работе представлен метод подготовки данных и последующая визуализация решения задачи Коши, которая возникает при моделировании динамики примеси в потенциальных течениях, а также при моделировании динамики примеси в вязкой несжимаемой жидкости в цилиндрической области течения. Задача Коши решалась с использованием метода Рунге–Кутты 4-го порядка точности. Разработано программное обеспечение для решения задачи Коши в трехмерном пространстве, которое в автоматическом режиме визуализирует полученные результаты. Такая постановка задачи может применяться для моделирования динамики течения безынерционной недиффундирующей примеси, растворенной в жидкости, в случае, когда векторное поле V , являющееся решением задачи Коши, удовлетворяет уравнениям гидродинамики. Задача Коши рассматривается на целом множестве начальных данных, задающем поле распределения примеси в начальный момент времени. Разработанное программное обеспечение позволяет проводить вычисления с распределением по доступным ядрам ЭВМ на основе технологии OpenMP. В качестве средства визуализации использовалась библиотека MathGL. Представлены результаты тестирования программного обеспечения.
this paper presents a method for data preparation and visualization of the solution to the Cauchy problem, which arises in simulating the dynamics of impurities in potential flows and in a viscous incompressible liquid within a cylindrical flow region. The Cauchy problem was solved using the 4th-order Runge-Kutta method. We developed software that solves the Cauchy problem in 3D space and automatically visualizes the results. This method can simulate the dynamics of an inertialess, non-diffusing impurity in a liquid, provided that the vector field V , which solves the Cauchy problem, satisfies the hydrodynamics equations. The problem is considered for the entire set of initial data defining the impurity distribution at the initial time. The software performs calculations distributed over available computer cores using OpenMP. The MathGL library was employed for visualization. The paper also presents the results of software testing.

Published: July 2024

Abstract. The objective of this study was to evaluate heterosis, general combining ability (GCA), maternal ability (GM), and sex-linked effects (SL) for growth performance from weaning (at 4 weeks) up to marketing age (at 12 weeks) using a complete 3×3 diallel crossing experiment in three different breeds of rabbit: one native Egyptian (Baladi Red, RR) and two exotic (Bauscat, BB, and Californian, CC). Offspring (2617 rabbits) body weight data (BW; 4–12 weeks of age) were analyzed, mainly to evaluate the effects of mating groups (MGs), sex, year season, and parity. MGs were further analyzed for crossbreeding parameters. All crossbreds showed positive, highly significant values (P≤0.001). Heterosis (HI; overall or specific) for body weight at all evaluated ages was highly significant (P≤0.001). Purebred differences were affected significantly (P≤0.01 or P≤0.001). No significant effects were detected due to general combining ability, maternal abilities, or reciprocal effect (sex-linked). Results suggest that to some extent and because of the highly purebred significant differences (P≤0.01 or P≤0.001), those three breeds are expected to be too genetically far apart to make crosses showing significant heterosis. Since other crossbreeding effects are non-significant, heterosis is the only reliable effect that can produce the Egyptian broiler rabbits when using those three breeds. However, the insignificance of the reciprocal impact (sex-linked as a whole or, by definition, the additive effects of genes carried on the sex chromosomes) of the two acclimatized standard breeds (CC and BB) seemed to be of magnitude at least to the 10th week of age.
Wind comparisons between meteor radar and Doppler shifts in airglow emissions using field-widened Michelson interferometers
Authors: Kristoffersen Samuel K. , Ward William E. , Meek Chris E. 
Published: July 2024

Abstract. Upper-atmosphere winds from a meteor radar and a field-widened Michelson interferometer, co-located at the Polar Environment Atmospheric Research Laboratory in Eureka, Nunavut, Canada (80° N, 86° W) are compared. The two instruments implement different wind-measuring techniques at similar heights and have very different temporal and spatial observational footprints. The meteor radar provides winds averaged over a ∼ 300 km horizontal area in 3 km vertical bins between 82 and 97 km on a 1 h cadence. The E-Region Wind Interferometer II (ERWIN) provides airglow-weighted winds (averaged over volumes of ∼ 8 km in height by ∼ 5 km radius) from three nightglow emissions (O(1S), oxygen green line, 557.7 nm, 97 km; an O2 line, 866 nm, 94 km; and an OH line, 843 nm, 87 km) on a ∼ 5 min cadence. ERWIN's higher precision (1–2 m s−1 for the O(1S) and OH emissions and ∼ 4 m s−1 for the O2 emissions) and higher cadence allows more substantive comparisons between winds measured by meteor radar and Doppler shifts in airglow emissions than previously possible for similar meteor radar/airglow Doppler shift comparisons using Fabry–Perot interferometers. The best correlation is achieved using Gaussian weighting of meteor radar winds with peak height and vertical width being optimally determined. Peak heights agree well with co-located SABER airglow observations. Offsets between the two instruments are ∼ 1–2 m s−1 for the O2 and O(1S) emissions and less than 0.3 m s−1 for the OH emission. Wind directions are highly correlated with a ∼ 1:1 correspondence. On average, meteor radar wind magnitudes are ∼ 40 % larger than those from ERWIN. Gravity wave airglow brightness weighting of observations is discussed. Non-quadrature phase offsets between the airglow weighting and gravity wave associated wind and temperature perturbations will result in enhanced or reduced layer-weighted wind amplitudes.

An acute coronary event in the presence of SARS-CoV-2 infection has its own characteristics that affect the course of the disease and the choice of treatment methods. Due to the lack of data on this category of patients, it is necessary to look for ways to determine the risk of adverse outcomes of this condition, including the difficulties of risk stratification. Aim: assessment of clinical and laboratory parameters and features of the clinical course in patients with ACS in combination with SARS-CoV-2 infection at the hospital stage. Construction of a prognostic model for the risk of death. Materials and methods. The study included 225 patients admitted to the regional vascular center with a diagnosis of ACS and a verified diagnosis of SARS-CoV-2 infection. Initially, 120 general clinical, biochemical and instrumental parameters were assessed. The second stage involved analysis of plasma metabolites in 73 patients. Results. A predictive model was constructed highlighting the eight most significant variables that correlate with in-hospital mortality in patients with ACS in combination with SARS-CoV-2: age, the presence of atrial fibrillation (except for that first detected in ACS), acute kidney injury, CKD above stage 2, severe and extremely severe course of SARS-CoV-2 infection, levels of ferritin, albumin and glycemia in the blood serum upon admission to the hospital. The present study identified new markers of mortality risk, such as C18 ceramide (d18:1/22:0) and ceramide (d18:1/24:0) levels. Conclusions. The proposed approach to assessing the risk of nosocomial death in acute coronary syndrome in combination with SARS-CoV-2 infection has good prognostic accuracy and is easy to use.

PERKEMBANGAN MADRASAH SEBAGAI INSTITUSI PENDIDIKAN ISLAM PALING MODERN PADA MASA DINASTI ‘ABBASIYAH (750-1250 M)
Authors: Wasito  
Published: July 2024

Penelitian ini hendak membahas terkait sejarah madrasah sebagai Lembaga Pendidikan yang paling maju di zaman keemasan Islam, dinasti Abbasiyah. Sebelum Dinasti Abbasiyah, pusat kegiatan Dunia Islam selalu bermuara pada masjid. Masjid dijadikan centre of education. Pada Dinasti Abbasiyah inilah mulai adanya pengembangan keilmuan dan teknologi diarahkan ke dalam ma'had. Lembaga ini kita kenal ada dua tingkatan yaitu maktab/kuttab dan masjid serta tingkat pedalaman. Pada perkembangan selanjutnya mulailah dibuka madrasah-madrasah yang dipelopori Nizhamul Muluk yang memerintah pada tahun 456-485 H. Lembaga inilah yang kemudian berkembang pada masa Dinasti Abbasiyah. Penelitian ini menggunakan metode penelitian kajian Pustaka. Yaitu sebuah penelitian yang mengkaji suatu objek pembahasan berdasarkan literatur pustakayang didapatkan. Penelitian ini menghasilkan temuan: 1) Motivasi yang mendasari kelahiran madrasah, yaitu selain motivasi agama dan motivasi ekonomi karena berkaitan dengan ketenagakerjaan, juga motivasi politik. 2) Meskipun madrasah sebagai lembaga pendidikan dan pengajaran di Dunia Islam baru timbul sekitar abad ke-4 H. Ini bukan berarti bahwa sejak awal perkembangannya Islam tidak mempunyai lembaga pendidikan dan pengajaran. Pada periode awal telah berdiri beberapa madrasah yang menjadi cikal bakal munculnya Madrasah Nizhamiyah. 3) Perhatian kaum Muslimin terhadap pendirian sekolah di segala penjuru negeri, menunjukkan betapa tinggi peradaban mereka. Umat Islam memandang bahwa ilmu merupakan asas setiap kemajuan.

Metode yang digunakan penulis dalam melakukan penelitian ini adalah melalui metode kualitatif deskriptif dengan kajian dokumen kepustakaan. Pengumpulan data diambil dari sumber berupa, literatur, artikel, buku dan dari website pendukung lainnya yakni kajian-kajian serta video di youtube. Kemudian dari data yang dikumpulkan lalu dituangkan dalam tulisan selanjutnya dianalisis dengan metode deskriptif. Konsep toleransi sudah digaungkan oleh para pendahulu pendiri bangsa ini dan bahkan jauh sebelum berdirinya Indonesia. Di dalam bertoleransi semakin banyak perbedaan maka semakin banyak pula diperlukan sikap tenggang rasa pengendalian diri dan pengertian. Jika ada pertentangan seperti apapun itu harus memiliki kesadaran untuk selalu menjaga kesetiakawanan, toleransi dan rasa persaudaraan.
'Walking to Work' Extract from The Backyard Adventurer (2021)
Authors: Miles Beau 
Published: July 2024

This paper is an extract from Beau Mile’s The Backyard Adventurer (2021) published by Brio Books. It is the text of the voiceover for the corresponding film ‘Walking 90 Kms to work’ available on Youtube - https://www.youtube.com/watch?v=R-Zyud8xh2c – Miles redefines adventure through his attempts to transform a mundane part of his life into an adventure. The first part of the text details missing travel and adventure when increasingly locked into a regular lifestyle, before deconstructing the necessity of travelling great distances or pushing oneself to extremes in order to experience adventure. In an attempt to demonstrate his argument, Miles decides to walk to work instead of driving. He documents his mindset and experiences when completing his daily 90km commute from a semi-rural lifestyle block to the inner city campus of the university where he works. The simple of idea of “walking to work” reveals how distanced we are from the spaces that surround our transport routes; how insulated we have become from the world around us. The text and film provides an intriguing performance of the philosophy that it articulates.
An African perspective of Helicobacter pylori infection: A narrative review
Authors: Funjika Evelyn , Cheuka Peter Mubanga , Zyambo Kanekwa , Chu Kathryn , Rickard Jennifer , Kayamba Violet 
Published: July 2024

Background
There is a high prevalence of Helicobacter pylori (H. pylori) infection in Africa, but data on its clinical presentation are limited. The African enigma, states that despite a high prevalence of H. pylori infection on the continent, related gastrointestinal diseases such as peptic ulceration and gastric cancer are not common. However, this conclusion was based on limited scientific evidence and has been challenged by some scientists.
Methods
This narrative review highlights gaps on our understanding of H. pylori infection in Africa, that limit the possibility of formulating evidence-based guidelines.
Results
We demonstrate a lack of understanding about the epidemiology of H. pylori-related gastric diseases such as peptic ulceration and gastric cancer. In addition, we discuss challenges related to drug resistance.
Conclusions
There is an urgent need to provide scientific evidence for the African enigma which will deepen our understanding of H. pylori infection on the continent. In addition, efforts at streamlining approaches to evidence-based eradication therapy need to be intensified.

Authors: Nambala Sianchapa Brenda , Mubita-Ngoma Catherine , Katowa-Mukwato Patricia 
Published: July 2024

Background: In an effort to prevent vertical transmission of HIV, pregnant women undergo HIV testing and where appropriate, are enrolled into HIV care. Receiving an HIV positive diagnosis can lead to stress and other experiences.
Aim: To explore the experiences of women diagnosed HIV positive during pregnancy at selected Health facilities in Lusaka district.
Methodology: A descriptive cross-sectional study design was used. In-depth interviews were conducted on 17 purposively selected postpartum women who were diagnosed HIV positive during their recent pregnancy. Data were analysed using thematic analysis. The 6-phase coding framework for thematic analysis was used to identify themes and patterns in the data
Major findings: Six main themes emerged: reactions to HIV diagnosis, stress of HIV diagnosis, making the HIV status known, ART adherence, staff behaviour and adjusting to the reality of living with HIV. Most participants reported a mixture of emotions upon receiving the diagnosis, including anger, disappointment, disbelief, shock, turmoil, with others becoming aggressive and contemplating physical harm to themselves and the foetus. Most participants reported being stressed about the diagnosis due to fear of vertical transmission and uncertainty about pregnancy outcome and future. Others reported Intimate Partner Violence upon disclosing to their sexual partners while some reported inconsistent ART adherence. Staff were generally described as being supportive, but some staff gave inadequate explanations, and some were rude.
Conclusion: The study recommends empathetic support by Health care providers, to women diagnosed with HIV during pregnancy, together with their significant others as they undergo the reality of living with HIV.
Origen y trayectoria del Departamento de Ciencias de la Tierra de FUNVISIS, Venezuela: sus primeros 50 años (1972-2022)

Published: July 2024

En el organigrama de FUNVISIS, creada como resultado benéfico del Terremoto de Caracas de 1967, el Departamento de Ciencias de la Tierra (DCT), desempeña el rol de puente entre las unidades de Sismología e Ingeniería Sísmica, cuyo desarrollo ocurrirá en 4 fases. En la inaugural (1972-1978), tal misión se efectúa sin personal especializado. Entre 1979 y 1983, se implementa el DCT a través de la cooperación científica francesa gracias a la formación “en caliente” de sus geocientíficos en sismotectónica. El DCT se consolida entre 1984 y 1996, con la ejecución de proyectos de aplicación por parte de geólogos con estudios de postgrado alcanzados en esa cooperación. La fase de expansión internacional más productiva del DCT ocurre entre 1997 y 2022. La proyección de su pericia en la región conlleva al reconocimiento de Venezuela como un país de vanguardia en geología de terremotos. Los años “dorados” del DCT se cierran abruptamente con la irrupción en Venezuela de una hiperinflación cabalgante en 2017, rematada por la pandemia del COVID 19. Tal situación económica empuja a sus jóvenes profesionales a los caminos de la diáspora, circunstancia agravada por la jubilación de sus profesionales seniors en 2020; con un futuro incierto para el DCT.

O feijão comum (Phaseolus vulgaris L.) é uma fabaceae de grande importância agrícola e alimentar, por ser fonte de proteínas, vitaminas, ferro e sais minerais, tornando-se um importante alimento na dieta básica da população brasileira. Foram inseridas as rizobactérias promotoras do crescimento de plantas – RPCP, dentre elas o Bacillus subtilis. Mediante a importância da utilização dessas rizobactérias o objetivo do trabalho foi o de avaliar a produtividade de cultivares de feijão sob doses de um produto a base de Bacillus subtilis. Os dados foram submetidos à análise de variância e quando constatada significância, foram avaliadas as seguintes variáveis: número de vagens por planta, número de grãos por planta, número de grãos por vagem, massa de 100 grãos, rendimento de grãos e teor de clorofila. As analises foram processadas com auxílio do software SISVAR. Com base nos resultados obtidos neste estudo, pode-se concluir que a aplicação de doses crescentes de Bacillus subtilis via adubação foliar, influenciou nos componentes de rendimento e na produtividade de feijão comum. A utilização da cultivar BRS FC 402 se destacou em relação ao número de semente/vagem, número de semente/planta e massa de 1000 grãos, indicando a importância da seleção adequada de cultivares para melhorar a produtividade. Essa cultivar é adaptada às principais regiões produtoras, testada e aprovada pela indústria (EMBRAPA, 2018).
