Authors: Salian Rishabh Baskara , Raj Nidhi , Achappa Basavaprabhu , Pai Suraj , Ahmed Arfath , Sajwan Svetanshu 
Published: December 2024

Background: Secondary hypertension is characterized by an elevated blood pressure greater than 140/90 mmHg, which occurs as a consequence of other diseases. The common etiologies of secondary hypertension include renal parenchymal causes, endocrine disorders, and vascular pathologies like coarctation of the aorta (CoA).
Case presentation: A 20-year-old patient was admitted to our hospital as he complained of headache and palpitations since one week. On examination, the blood pressure in his right upper limb was 180/100 mmHg. The volume of the femoral and the dorsalis pedis pulses was found to be reduced bilaterally. The patient was started on antihypertensive medication labetalol 10 mg injection intravenously immediately. After clinical suspicion and a series of investigations, the patient was diagnosed with severe CoA, distal to the origin of the left subclavian artery via computed tomography (CT) aortogram. The patient was managed by coarctoplasty with stenting.
Discussion: The most striking examination findings indicative of CoA include decreased lower limb pulses and a blood pressure difference of >20 mmHg across both the lower and upper extremities. It is important to evaluate the blood pressure in both upper and lower limbs to diagnose obstructive vascular diseases.
Conclusion: The presence of multiple well-developed collaterals can often mask symptoms and delay the detection of hypertension in patients with CoA. Patients with CoA require regular follow-up to monitor left ventricular outflow tract obstruction, and patients with severe CoA should be treated interventionally to prevent complications including aortic aneurysm and dissection.
The patient was managed by coarctoplasty with stenting and recovered well post-surgery.
МИНЕРАЛОГО-ПЕТРОГРАФИЧЕСКОЕ ИССЛЕДОВАНИЕ ФОРМОВОЧНОЙ МАССЫ КНИДСКИХ АМФОР

Published: December 2024

В статье представлены результаты петрографического исследования 32 образцов керамики, полученных с целых и фрагментированных амфор, в том числе клейменых. Материал охватывает период с середины IV по конец II в. до н.э. Проведенный анализ шлифов позволил выделить четыре петрографические группы формовочной массы, две из которых (А и В) надежно соотносятся с мастерскими Книда. Локализация доказывается наличием в обеих группах клейм, чье книдское происхождение не вызывает сомнения. Высказывается предположение, что амфоры обеих групп были изготовлены в местечке Решадие (Reșadie). Оно основано на результатах сборов и археологических раскопок, проводившихся в этом районе. Разнообразие минералогического состава тканей сосудов, образцы с которых вошли в группы C и D, позволяет говорить о том, что амфоры были изготовлены за пределами Книдского полуострова.
The article presents the results of a petrographic study of 32 ceramic samples obtained from whole and fragmented amphorae, including stamped ones. The material covers the period from the middle of the 4th to the end of the 2nd century BCE. The analysis of the thin sections made it possible to identify four petrographic groups of the molding mass, two of which (A and B) reliably correlate with the Knidos workshops. Localization is proved by the presence of stamps in both groups, whose Knidian origin is beyond doubt. It is suggested that the amphorae of both groups were made in the Reșadie. It is based on the results of amphora assemblage and archaeological excavations conducted in the area. The diversity of the mineralogical composition of the vessel tissues, samples from which were included in groups C and D, suggests that the amphorae were made outside the Knidian Peninsula.
КАМЕННЫЕ ПЛИТЫ ИЗ СКИФСКИХ ЗАХОРОНЕНИЙ ЛЕВОБЕРЕЖЬЯ НИЖНЕГО ДНЕСТРА
Authors: Хотылев А.О. , Майоров А.А. , Синика В.С. 
Published: December 2024

В статье анализируются 43 каменные плиты из скифских захоронений левобережья Нижнего Днестра V—II вв. до н.э. Они происходят из мужских и женских погребений и использовались, вероятно, в качестве столов, на которые ставились различные предметы. Плиты имеют разные форму и размеры. Изучение состава горных пород показало, что плиты изготавливались из обломочных (песчаники, кварциты и алевролиты), и реже — карбонатных (известняки) пород, а весь каменный материал имеет местное происхождение. С течением времени количество плит в скифских погребениях региона увеличивается, а требования к правильности их форм и тщательности обработки снижаются, при этом заметна тенденция к отбору определённых горных пород (песчаников с карбонатным цементом), из которых они изготавливались. Скорее всего, это связано с природной трещиноватостью данных пород, которая позволяла легко получать плиты нужного размера.
The article analyzes 43 stone slabs from Scythian graves on the left bank of the Lower Dniesterdated to the 5th — 2nd centuries BCE. They come from male and female burials and were probably used as tables on which various objects were placed. The slabs have different shapes and sizes. A study of the composition of the rocks showed that the slabs were made of clastic (sandstones, quartzites and siltstones), and less often carbonate (limestones) rocks, and all stone material was of local origin. Over time, the number of slabs in Scythian burials in the region increases, and the requirements for the correctness of their shapes and thoroughness of processing decrease, while there is a noticeable tendency to select certain rocks (sandstones with carbonate cement) from which they were made. Most likely, this is due to the natural fracturing of these rocks, which made it easy to obtain slabs of the required size.

Abstract: “Network Function Virtualization” (NFV) is an emerging technology and 5G key enabler. It promises operating expenditure savings and high flexibility in managing the network by decoupling the network functions, like firewalls, proxies etc., from the physical equipments on which they run. In order to reap the full benefits of NFV, some challenges still need to be overcome, namely those related to resource management, security and anomaly detection. Recently, Machine learning (ML) has been applied in different fields and has demonstrated amazing results. Utilizing Machine learning to address the challenges faced by NFV is a promising research field that requires further investigation. In this paper, we shed light on this domain by discussing the potential and challenges of ML application to NFV and by surveying existing works.

Published: December 2024

Prevention of tuberculosis among the population is difficult without coordinated and organized interaction between the TB service and primary outpatient care.The aim was to improve the system of interaction between local TB doctors and general practitioners using the NextGIS QGis geographic information system to improve the quality of preventive measures.Materials and methods. Information on the attachment of residential buildings of the district to the city polyclinics was used, as well as distribution of addresses between phthisiatric sections of anti-tuberculosis dispensary No. 14. NextGIS QGis version 24.2.1 with vector analysis tools was used to process spatial data. To assess the epidemiological situation, cartographic visualization using the method of thematic point layers and heat maps was used, built on the basis of data on tuberculosis patients from dispensary observation groups 1–3, registered in 2019– 2024.Results. Offline maps of polyclinic sites in comparison with the boundaries of phthisiatric sites allowed visualization of epidemically compromised sites with the reflection of data on TB cases, contact information of the therapist and TB specialist responsible for providing medical care to the assigned population; a tool was obtained for generating analytical information, necessary for a phthisiatrician and a general practitioner to work together.Conclusion. The use of a geographic information system makes it possible to increase the efficiency of interaction between medical organizations, optimize collegial decisions on preventive examinations of the population of the region, organize examination, treatment and dispensary observation of tuberculosis patients.

Published: December 2024

The main problem in the treatment of tuberculosis (TB) patients is the increase in drug resistance of M.tuberculosis, which is not always detected at the start of chemotherapy, which leads to inadequate and lengthy treatment.Research objective. Analysis of the treatment of newly diagnosed patients according to the regimen of drug-sensitive TB.Materials and methods. We analyzed the facts of correction of the regimen and the timing of the intensive phase of chemotherapy in 55 newly diagnosed patients with pulmonary TB who were taken for treatment according to regimen of drug-sensitive TB in 2019–2021.Results. At the start of treatment, bacterial excretion and drug sensitivity of M. tuberculosis were confirmed by microscopy and molecular genetic tests only in 9 (16.4%) patients. Results of cultural tests confirm the bacterial excretion in 23 (41.8%) patients. Of these, 10 patients (43.6%; 18.2% of those who started treatment, 21.7% with no data on bacterial excretion at the start of chemotherapy) received data on drug resistance during treatment (7 – MDR, 2 – pre-XDR, one had resistance to isoniazid), which required a change in regimen with an extension of the intensive phase to 8 months. Of the remaining 45 patients, in 29 the duration of the intensive phase was 2 months, in 15 with HIV infection – 3 months; in one patient the intensive phase was prolonged to 5 months due to poor tolerability.Conclusion. A change of treatment regimen due to drug resistance was required in 18.2% of newly diagnosed TB patients with suspected drug sensitivity of the pathogen. It is necessary to improve management strategies for newly diagnosed patients with oligobacillary pulmonary tuberculosis.

Published: December 2024

Genitourinary tuberculosis is one of the most common extrapulmonary forms of tuberculosis, the diagnosis of which is difficult due to the lack of specific symptoms. One of the rare forms of renal tuberculosis is tuberculous interstitial nephritis. Isolated cases of this pathology have been described.A clinical case of tuberculous interstitial nephritis in a 56-year-old patient is presented. During the diagnostic search, a puncture biopsy of the kidneys was performed, which revealed signs of active granulomatous interstitial nephritis and focal necrotizing glomerulonephritis. Acid-fast mycobacteria were detected in the urine. The patient received anti-tuberculosis chemotherapy (levofloxacin, ethambutol, phenazide, rifampicin, ertapenem), given the decrease in the glomerular filtration rate (GFR) to 3.4 ml/min/1,73м2, renal replacement therapy was carried out renal replacement therapy (hemodialysis 4 hours 2 times a week). After 4 months of treatment, an improvement in renal function was noted (GFR 12 ml\min\1,73м2), which required switching to hemodialysis and transferring the patient to the continuation phase of chemotherapy. A repeat kidney biopsy was performed, which revealed chronic granulomatous interstitial nephritis, interstitial fibrosis and grade 3 tubular atrophy.Conclusion. Timely diagnosis using puncture biopsy of the kidneys and adequate etiotropic therapy can restore kidney function in tuberculous interstitial nephritis.

This study analyzes the application of the order costing method with a variable costing approach at PT Makmur, a manufacturing company engaged in the beverage cup industry. Accurate determination of the cost of goods manufactured is crucial to support strategic decision making, profit optimization, and management of company resources. This research uses a literature study method with a qualitative approach to explore in-depth understanding related to the calculation of production costs. The results of the analysis show that the variable costing method provides benefits in identifying contribution margins and controlling variable costs, while the full costing method tends to produce a more comprehensive estimate of production costs by including fixed costs. The findings indicate a significant difference in net profit between the two methods, which has an impact on selling pricing decisions and production strategies. The implication of this study is that it provides practical guidance for PT Makmur and similar companies to choose a costing method that suits financial and operational objectives, and improve competitiveness through more efficient cost management.

Introdução: A pandemia causada pela COVID-19, iniciada em dezembro de 2019, causou efeitos significativos tanto na saúde pública quanto nas condições de vida dos indivíduos na maioria dos países. No contexto acadêmico brasileiro, as instituições de ensino interromperam o calendário acadêmico e administrativo em março de 2020, visando proteger a saúde e o bem-estar da comunidade escolar. Objetivo: O presente estudo tem por objetivo realizar uma revisão integrativa de literatura sobre o impacto da pandemia da COVID-19 na qualidade de vida dos docentes. Metodologia: Trata-se de uma revisão integrativa de literatura, no qual foram realizadas as buscas nas bases de dados da Biblioteca Virtual em Saúde (BVS), LILACS, MEDLINE, PUBMED e Scielo. A busca limitou-se aos artigos em português e inglês e compreendeu os anos de publicação entre 2020 a 2024. Resultados: Do total de 235 artigos, 162 foram excluídos por duplicidade, outros foram excluídos por não estarem em consonância com a temática ou por não responderem à questão norteadora, selecionando-se ao final 5 artigos para essa revisão. A partir da leitura dos artigos percebe-se uma alta prevalência de sintomas de estresse, ansiedade e depressão entre professores. Além de impactos significativos na qualidade de vida e na saúde mental dos docentes, com destaque para a insatisfação com o ensino remoto e a falta de apoio institucional. Conclusão: Os estudos indicam que a pandemia aumentou o estresse, agravou a saúde mental e dificultou o ensino remoto para docentes. Fatores como carga horária excessiva, falta de treinamento e sobrecarga prejudicaram a saúde física e psicológica. É urgente adotar políticas públicas de suporte psicológico, capacitação tecnológica e melhores condições de trabalho.

Published: December 2024

Inúmeros pesquisadores referem-se ao uso excessivo do jargão técnico-jurídico como ‘juridiquês’ na prática social diária do Direito no Brasil. Nesse sentido, é válido considerar que o termo "juridiquês" refere-se ao jargão característico do direito, que, embora necessário para a precisão técnica, pode criar barreiras de compreensão tanto para leigos quanto para profissionais de outras áreas. Assim, a análise dos pressupostos discursivos na linguagem jurídica envolve a identificação de normas, convenções e estruturas que moldam o discurso legal ao revelar como essas características influenciam a interpretação e a aplicação do direito. Dito isto, os aportes possíveis incluem a necessidade de simplificação e clareza na comunicação jurídica com a utilização de uma linguagem mais acessível que pode contribuir para a democratização do conhecimento jurídico, permitindo que um maior número de pessoas compreenda seus direitos e deveres. Além disso, a reflexão sobre a linguagem jurídica pode levar a uma crítica das relações de poder que permeiam o discurso legal, uma vez que a complexidade da linguagem pode ser utilizada para manter o controle sobre o conhecimento e a informação. Portanto, o estudo do "juridiquês" propõe um diálogo entre linguística e direito, visando promover uma comunicação mais eficaz na construção de um discurso jurídico que equilibre precisão técnica e clareza para a inclusão social e a efetivação dos direitos - essa abordagem crítica representa um avanço na reflexão sobre a linguagem enquanto instrumento de justiça e cidadania.
Numerical Simulation Study on the Average Air Velocity Circle in Coal Mine Roadway
Authors: He Min 
Published: December 2024

To determine the accurate installation position of the air velocity sensor and ensure that it monitors the average air velocity of the full section of the roadway, a numerical simulation method was employed. The results verified the existence of an average air velocity circle on the section of a fully developed turbulent roadway, where the air velocity at any point on it is equal to the average air velocity of the roadway, and its position is approximately fixed, independent of the size of the roadway air velocity. It revealed the rule that the distance from the top of the average air velocity circle to the roof of rectangle, semi-circular arch, and three-centered arch roadways with smooth walls is 0.11-0.12 times the height of the roadway. Through field tests, it was found that in real underground roadways, the distance from the average air velocity circle to the roof is greater than that in roadways with smooth walls. When installing air velocity sensor in real roadway, the installation position of the sensor should be adjusted appropriately based on the roughness of the roadway wall surface.

The thermal vacuum test is a very crucial assessment test in the space environment testing of aerospace power supply products. In the process of the test, facing the complex and diverse module power supply, there is no unified standard to define the specific installation status of the product, which causes the overheating problem of the same product in different installation status under the same test conditions. In order to solve this problem, this paper carried out a test verification study on different installation status of the product, and analyzed the influence of different installation and fastening states of the product, the contact state between the fixture plate and the cold plate, the product placement direction and placement position on the thermal vacuum test. And give rationalization suggestions for the installation status of thermal vacuum test of other aerospace products to reduce the risk of thermal vacuum test of products.
Effects of Three Factors on Anionic Redox Reactions in Li-doped Mn-based Layered Oxide Cathodes for Na-ion Batteries
Authors: Zhang Yixuan , Liu Guoqiang 
Published: December 2024

Anionic redox reactions (ARR) in Mn-based layered oxides for sodium-ion batteries have gained attention recently. Lithium doping is often used to activate ARR. This study examines three factors affecting the structure and electrochemical performance of NaxLiyMn1-yO2: sodium content, lithium content, and quenching temperature after calcination. With a fixed Li content of 0.1, ARR contribution first decreases, then increases as sodium content rises from 0.64 to 0.69. Higher quenching temperatures increase initial Mn3+ content, reducing ARR capacity and open-circuit voltage while promoting Mn3+ oxidation. Varying Li content alters the material's structure, morphology, and electrochemical properties; a Li content of 0.175 enhances ARR, achieving maximum capacity and stability in Na0.67Li0.175Mn0.825O2. This work advances the use of ARR in layered oxide cathodes for sodium-ion batteries.
