Abstract
Budd–Chiari syndrome is a rare disease and is a significant cause of cirrhosis. We report a clinical case of a 23-year-old patient, highlighting the diagnostic and therapeutic difficulties of Budd–Chiari syndrome at the cirrhosis stage in a country with limited resources such as Togo. A 23-year-old, nonalcoholic, patient who tested negative for hepatitis B and C virus presented with progressive abdominal distension. Examination revealed grade 2 ascites and soft, painless, cold, bucketing edema of the lower limbs rising to the knees. The calculated serum-ascites albumin gradient was 12 g/L. Abdominal ultrasound and abdominal computed tomography indicated the presence of thrombosis of the inferior vena cava, which ascended to the hepatic veins. Biological signs of hepatocellular insufficiency such as a low prothrombin time (56%) and low serum albumin levels (22 g/L) with a beta-gamma block were also found. Upper gastrointestinal endoscopy revealed grade 3 esophageal varices with red signs. The diagnosis of Budd–Chiari syndrome at the stage of cirrhosis classified as Child–Pugh score 9 decompensated in the ascitic mode, complicated by grade 3 esophageal varices with red signs, was retained. Due to the inadequacy of the technical facilities in Togo, and also because of financial difficulties, aetiological work-up was not carried out. Anticoagulant treatment with rivaroxaban 10 mg/day has been instituted. The clinical outcomes were poor with gastrointestinal bleeding, stage 3 hepatic encephalopathy, and death on the 46th day. The prognosis of Budd–Chiari syndrome is poor in resource-limited countries such as Togo. It depends on the quality of care, not only of the etiology but also of the complications of cirrhosis.

Published: December 2024

Abstract
Viral anterior uveitis (AU) can be caused by a multitude of viruses, including cytomegalovirus (CMV). It can be a potentially vision-threatening condition. Thus, it requires prompt diagnosis and treatment as well as long-term prophylaxis to prevent the dire effects of recurrences. This case involved a 45-year-old Egyptian woman with a long history of unilateral recurrent AU that was polymerase chain reaction proven to be due to CMV. She was treated with oral valganciclovir and then placed on maintenance therapy. In this case, we shed the light on the possibility of reducing the prophylactic dose to a 450 mg biweekly dose of oral valganciclovir. Considering a lower dose of oral valganciclovir may help practitioners avoid the side effects of oral valganciclovir as well as reduce the overall financial burden in long-term prophylaxis.
Spectral response of forest disturbances induced by beaver caused floods: A case study in Estonia using Sentinel-2 MSI image time series
Authors: Kaha Mihkel , Lang Mait 
Published: December 2024

Beavers are known as ecosystem engineers and the habitats that they create can change the landscape greatly. When a new beaver colony establishes itself by building dams, digging canals and burrows and felling trees, the resulting changes are often large enough to be studied with medium resolution earth observation sensors like Sentinel-2 MSI. In this study we compare the spectral signatures of 405 sample areas disturbed by beaver-induced flooding with 261 healthy forest sample areas surrounding the area. We used 28 Sentinel-2 MSI multispectral images from years 2015 to 2018 over the southern part of Estonia in Military Grid Reference System map tile T35VME. In summer the average pixel values for areas that are affected by beavers show the largest differences in reflectance values for shortwave infrared (SWIR) and the visible parts of the spectrum compared to areas that are not affected by beavers. Some smaller differences are present also in the near-infrared (NIR) parts of the spectrum, but sometimes they are not significant according to p-values, being over the 0.05 threshold, of the t-test. In autumn and spring, when deciduous trees do not have their leaves and ground vegetation is not thriving, the differences in visible parts of the spectrum disappear. Multispectral vegetation indices, like the Normalized Difference Vegetation Index (NDVI) and others, also show clear differences in the beaver-disturbed forests and surrounding healthy forests throughout all vegetation phenology stages.

Published: December 2024

The objective of this research is to examine energy consumption efficiency strategies with respect to the type of dwelling unit, cooling load, and thermal comfort. This can be evaluated through the study of the hotel building air system, with the aim of ensuring the thermal comfort of its occupants. This research employs a quantitative methodology, using observation, measurement, and experimental techniques. The case study is situated within the context of hotels in Makassar City, South Sulawesi Province, Indonesia. The subject of this study is the Swissbel Hotel building, located in the coastal area of Makassar City. The data are analyzed in order to determine the Energy Consumption Intensity (IKE), Room Energy Intensity (REI), and occupancy rate based on the heat load inside and outside the building. The data are then processed using a parametric statistical approach. Subsequently, the building envelope is analyzed through the calculation of the Overall Thermal Transfer Value (OTTV) in accordance with the standards set out in SNI 6390: 2011. The cooling load and a thermal comfort assessment, in line with the Predicted Mean Vote (PMV) index, Predicted Percentage of Dissatisfaction (PPD) index, and effective temperature according to the ASHRAE 55-2022 standard, are then calculated, and a simulation is performed to determine the most efficient strategy for the use of air conditioning energy. The findings indicated that alterations in the dimensions of the facade (sun shading) resulted in a 16% reduction in the cooling load, with the incorporation of horizontal and vertical shading sizes of 4 m × 2.5 m, square glass openings, and 8 mm heat-absorbing glass. This led to a PMV value of 0.40, a PPD of 8%, and an effective temperature value of 26.8°C. The modification resulted in a percentage gain of 20.08%, at 10-60% occupancy load with a cooling load reduction rate of 1,912,071 kW and a thermal comfort index within the comfortable range.

Published: December 2024

Хорошо известно, что динамика солнечной короны определяется магнитным полем. С другой стороны, измерить величину и определить структуру коронального магнитного поля невозможно из-за теплового уширения. По этой причине поле в короне может быть реконструировано с использованием данных, полученных с помощью магни- тограммы и физики бессиловых полей. Здесь мы предлагаем метод ограниченной оптимизации с использованием векторного множителя Лагранжа и сравниваем результаты с результатами существующих моделей. Численный ана- лиз нашей модели был проведен с помощью наблюдательной векторной магнитограммы, полученной с помощью изображений SDO/HMI. Мы приходим к выводу, что 1) лагранжиан в настоящей модели сходится немного быстрее, чем в моделях сравнения. 2) Поведение магнитной свободной энергии в процессе оптимизации согласуется с поведени- ем в предыдущих исследованиях. 3) Разработана модель для реальной магнитограммы. Вычислены такие величины, как содержание магнитной энергии, текущий взвешенный угол между вектором плотности тока и магнитным полем и относительные ошибки потока.
It is well known that the dynamics of the solar corona is governed by the magnetic field. On the other hand due to the thermal broadening it is not possible to measure the magnitude and determine the structure of the coronal magnetic field. For this reason, the field in the corona may be reconstructed using the data obtained by the magnetogram and the physics of force-free fields. Here we propose a method of constrained optimization using the vector Lagrange multiplier and compare the results with those of ever present models. The numerical analysis of the our model was conducted through an observational vector magnetogram obtained by SDO/HM I images. We conclude that i) the Lagrangian in the present model converges slightly faster than that of comparison models. ii) the behavior of the magnetic free energy during the optimization is compatible with those of the previous studies, iii) the model is worked out for a real magnetogram and the corresponding quantities such as magnetic energy content, the current weighted angle between the current density vector and magnetic field, and the fractional flux errors are computed.
К вопросу о существовании кометного семейства Урана
Authors: В.С. Усанин 
Published: December 2024

Ранее считалось общепризнанным деление комет в зависимости от их афелийных расстояний на семейства Юпи- тера, Сатурна, Урана и Нептуна. Современная классификация оставляет только семейство Юпитера, а семейства Сатурна, Урана и Нептуна заменены галлеевским типом. Переход от старой классификации к новой до сих пор вы- зывает критику. В качестве одной из характеристик динамической связи комет с планетами предлагался критерий Радзиевского-Тиссерана, который имеет смысл большой полуоси орбиты возмущающей планеты. В данной статье, продолжающей предыдущую работу по семейству Сатурна, критерий Радзиевского-Тиссерана применен к кометам Кроммелина (27P), Стефана-Отерма (38P) и Темпеля-Тутля (55P) для проверки гипотезы об их принадлежности к семейству Урана. Ни одно значение критерия, вычисленное с учетом различных факторов, не лежит между боль- шими полуосями орбит Сатурна и Нептуна. Таким образом, динамической связи этих комет с Ураном не выявлено. Подтверждается современная классификация комет.
Earlier, the division of comets depending on their aphelion distances into the planetary families of Jupiter, Saturn, Uranus and Neptune was regarded as undoubted. The modern classification system retains only the Jupiter family, and the families of Saturn, Uranus and Neptune are replaced by the Halley type. The transition from the old classification system to the new one still raises criticism. The Radzievskij-Tisserand criterion, which fits the orbital semimajor axis of the perturbing planet, was proposed as a measure of the dynamical relation of comets to planets. In the present paper, continuing the previous work on the Saturn family, the Radzievskij-Tisserand criterion is applied to comets 27P/Crommelin, 38P/Stephan-Oterma, and 55P/Tempel-Tuttle for the evaluation of the hypothesis that they belong to the Uranus family. No one value of the criterion calculated considering different factors lies between the Saturn and Neptune’s orbital semimajor axes. So, no dynamical relation of these comets to Uranus is revealed. The modern comet classification system seems to be right.

Published: December 2024

Статья посвящена модернизации метеорного радара на базе системы SKiYMET в Казанском федеральном универ- ситете. Целью модернизации является повышение точности радиолокационных наблюдений за метеорами. В ходе модернизации количество антенн увеличилось с 5 до 12, а размеры измерительных баз были расширены до 220 м на 150 м. Эти изменения значительно улучшили точность измерений угловых координат, достигая значений не хуже 0.3 градуса. Также представлены статистические данные мониторинга, проведенного в 2023 г., по которым количество зарегистрированных метеоров с оценкой скорости метеора варьировалось от 15000 до 40000 в сутки. На основе анализа выявленных проблем и статистических данных предложены направления для дальнейшего развития радиолокационного метода наблюдений за метеорами в Казанском федеральном университете. Для повышения точ- ности наблюдений и расширения возможностей метеорного комплекса по регистрации метеорных следов и изучению притока метеорного вещества предлагается увеличить длину измерительных баз до 400 м на 200 м, и также устано- вить дополнительные антенны и приемные комплексы, оснащенные фазовыми интерферометрами, размещенными с значительным пространственным разносом, а также организовать совместные наблюдения метеорных явлений.
This paper focuses on the modernization of the meteor radar system based on SKiYMET at Kazan Federal University. The goal of this modernization is to enhance the accuracy of radar observations of meteors. As part of the upgrade, the number of antennas was increased from 5 to 12, and the measurement baseline was expanded to 220 meters by 150 meters. These enhancements significantly improved the precision of angular coordinate measurements, achieving accuracies of 0.3 degrees or better. Additionally, the article presents monitoring statistics from 2023, which indicate that the number of recorded meteors with velocity estimates varied between 15,000 and 40,000 per day. Through a detailed analysis of the encountered challenges and statistical data, several directions for the further development of radar meteor observation methods at Kazan Federal University are proposed. To further improve observational accuracy and expand the meteor radar system’s capabilities for detecting meteor trails and studying the influx of meteoric matter, it is proposed to increase the measurement baseline to 400 meters by 200 meters. This also includes the installation of additional antennas and receiving systems equipped with phase interferometers positioned with significant spatial separation, as well as the organization of joint observations of meteor phenomena.
