Published: February 2025

Introdução: A osteoporose é definida como uma doença crônica não transmissível, cujo desenvolvimento está associado a influências genéticas, hábitos e fatores ambientais. O aumento de sua prevalência na sociedade brasileira está associado, sobretudo, à adesão de maus hábitos, como o vício em tabaco, que, atualmente, é comercializado de diferentes formas, como canetas eletrônicas, pen drives e cigarros, os quais emitem fumaça, que quando inalada de forma passiva ou ativa podem gerar danos a homeostasia humana.Objetivo: Este estudo teve como objetivo revisar evidências presentes na literatura acerca do desenvolvimento de osteoporose em adultos expostos ao longo da vida à fumaça ativa do tabaco e a fumaça ambiental. Metodologia: Revisão sistemática realizada nas bases MEDLINE, LILACS e BVS, utilizando o operador Booleano AND e os descritores osteoporosis e tobacco. Foram incluídos artigos publicados de 2019 a 2024, nos idiomas português ou inglês, que abordassem a osteoporose em adultos.Resumos, trabalhos duplicados,sem acesso gratuito, e fora da temática do artigo artigo foram excluídos. Discussão: O tabagismo é um grande problema de saúde pública, pois, além de afetar os sistemas cardiovascular e respiratório, também pode gerar danos ao sistema ósseo, tanto de forma direta quanto indireta, um fator relevante na análise da expectativa de vida no Brasil. Conclusão: Diante disso, os danos a esse sistema afetam a mobilidade e a independência, além de estarem associados a outras doenças crônicas. Como consequência, sobrecarregam o Sistema Único de Saúde, aumentando as filas e dificultando o atendimento e o acesso aos cuidados necessários.

Ежегодно в Российской Федерации более 30% площади всего лесного фонда подвергаются воздействию пожаров. Объекты, находящиеся в непосредственной близости от лесных пожаров, воспламенятся из-за исходящих тепловых потоков. Для защиты данных объектов в 90% случаев применяются водные завесы. В рамках данной работы были проведены экспериментальные исследования по определению оптимального диаметра капель распылённых струй воды для защиты объектов от лесных пожаров. Создана модель движения капли в условиях высоких тепловых потоков, она предназначена для определения диаметра капли воды и водных растворов, при котором период ее испарения совпадает со временем, необходимым для прохождения капли через высокотемпературные тепловые потоки пожара. Согласно полученным результатам экспериментального исследования, начиная с 7 минуты, происходило эффективное ослабление тепловых потоков от горения древесины. Стоит отметить, что изменение фиксируемой температуры с 480℃ до 100℃ происходит менее чем за минуту. Проведенной серией моделирования было установлено, что для наиболее эффективного снижения тепловых потоков от лесных пожаров необходимо создавать распыление с диаметром капель порядка 150-200 мкм.
Every year in the Russian Federation, more than 30% of the area of the entire forest fund is exposed to fires. Objects located in the immediate vicinity of forest fires will ignite due to outgoing heat flows. In 90% of cases, water curtains are used to protect these objects. As part of this work, experimental studies were conducted to determine the optimal diameter of droplets of sprayed water jets to protect objects from forest fires. A model of the movement of a drop in conditions of high heat flows has been created, it is designed to determine the diameter of a drop of water and aqueous solutions, at which the period of its evaporation coincides with the time required for the drop to pass through the high-temperature heat flows of a fire. According to the results of the experimental study, starting from 7 minutes, there was an effective weakening of heat fluxes from gorenje wood. It is worth noting that the change in the fixed temperature from 480℃ to 100℃ occurs in less than a minute.

Published: February 2025

В статье исследуются и анализируются существующие методы поддержания работоспособности пожарных рукавных линий и их элементов в условиях отрицательных температур. Особое внимание уделяется насосно-рукавным системам (НРС), подверженным перемерзанию, таким как трёхходовые пожарные разветвления (РТ) и соединительные головки. Основной целью работы является определение минимальной температуры воздуха внутри защитного кожуха РТ, создаваемой тепловым потоком от работающей паяльной лампы, для предотвращения перемерзания при тушении пожаров в условиях отрицательных температур. В процессе эксперимента использовался кожух, выполненный из листовой стали толщиной 2 мм, соответствующий размерам РТ-80. Для измерения температур применялись термопары, установленные на различных уровнях кожуха. Данные регистрировались с интервалом в две секунды. Анализ результатов показал, что минимальная температура внутри кожуха достигала 200°C уже через минуту после начала нагрева, что достаточно для предотвращения замерзания воды в РТ. Авторы заключают, что использование кожуха в комплексе с паяльной лампой значительно повышает надёжность насосно-рукавных систем в условиях отрицательных температур.
The article studies and analyses the existing methods of maintaining the serviceability of fire hose lines and their elements in conditions of subzero temperatures. Particular attention is paid to pump and hose systems (PSS) subject to freezing, such as three-way fire branch lines (FB) and connecting heads. The main objective of this work is to determine the minimum air temperature inside the protective casing of a PT, created by the heat flux from a running blowtorch, to prevent freezing when extinguishing fires in sub-zero temperatures. In the course of the experiment a casing made of 2 mm thick steel sheet corresponding to the dimensions of FB-80 was used. Thermocouples installed at different levels of the casing were used to measure temperatures. The data were recorded at two-second intervals. Analyses of the results showed that the minimum temperature inside the shroud reached 200°C within one minute after the start of heating, which is sufficient to prevent water freezing in the PT. The authors conclude that the use of the shroud in combination with a blowtorch significantly improves the reliability of pumping hose systems in sub-zero temperatures.

В условиях современного динамичного и конкурентного рынка успех нового товара или услуги зависит от грамотного продвижения, которое не только информирует потребителей, но и формирует имидж бренда, увеличивает лояльность клиентов и способствует коммерческому успеху. Эффективная маркетинговая политика должна учитывать потребности целевой аудитории, исследовать конкурентную среду и разрабатывать стратегии, направленные на создание спроса. Однако выбор подходящей стратегии не всегда очевиден, что требует гибкости и корректировок. В статье предлагается математическая модель, основанная на теории Марковских случайных процессов, для анализа эффективности продвижения новых продуктов. Рассматриваются ключевые состояния процесса: начальная реализация стратегии, её корректировка и успешное завершение продвижения. Уравнения Колмогорова и преобразование Лапласа используются для вычисления вероятностей различных этапов. Анализ модели демонстрирует, что вероятность успешного продвижения продукта зависит от продолжительности промежуточных этапов. Сокращение этих этапов способствует ускорению вывода товара на рынок. Графические зависимости показывают, что вероятность завершения процесса стремится к единице, тогда как промежуточные состояния со временем затухают. Применение модели позволит компаниям оптимизировать маркетинговые стратегии, повысить их эффективность и минимизировать риски, связанные с выбором неудачной стратегии продвижения.
In today's dynamic and competitive market, the success of a new product or service depends on competent promotion, which not only informs consumers, but also builds brand image, increases customer loyalty and contributes to commercial success. An effective marketing policy should take into account the needs of the target audience, research the competitive environment and develop strategies aimed at creating demand. However, the choice of an appropriate strategy is not always obvious, which requires flexibility and adjustments. The paper proposes a mathematical model based on the theory of Markov Random Processes to analyse the effectiveness of new product promotion. The key states of the process are considered: initial implementation of the strategy, its adjustment and successful completion of the promotion. Kolmogorov equations and Laplace transform are used to calculate the probabilities of the different stages. The analysis of the model demonstrates that the probability of successful product promotion depends on the duration of the intermediate stages. Reduction of these stages contributes to the acceleration of the product launch. The graphical dependencies show that the probability of process completion tends to one, while the intermediate states fade with time. The application of the model will allow companies to optimise marketing strategies, increase their efficiency and minimise the risks associated with the choice of unsuccessful promotion strategy.

Importance: Cutaneous melanoma is regarded as the most lethal form of skin cancer. According to the literature, issues associated with accurate prognosis and early detection of relapses hinder effective treatment of melanomas. Over the past 20 years, microRNAs have been shown to modulate various biological processes. Disruption of microRNA expression and activity can contribute to the risk of cancer development, including cutaneous melanoma. Therefore, we decided to study some microRNAs as biomarkers for future use in cutaneous melanoma diagnosis.Objective: To analyze the expression of microRNA-205, microRNA-199a-3p, microRNA-146a-5p in tumor tissue of patients diagnosed with cutaneous melanoma.Materials and methods: We quantified the expression of microRNA-205, microRNA-199a-3p, microRNA-146a-5p using the realtime polymerase chain reaction in biopsy specimens from patients with melanoma (n=14). For all the specimens, the cycle threshold (Ct) value was 0.1 (qPCRsoft 3.0, Analytik Jena, Germany). Statistical analysis was performed using Statistica 7.0 (StatSoft, USA). Furthermore, we conducted a bioinformatics search for microRNA target genes using DIANA-mirPath v.3.0 (DIANA-Lab, Greece) and constructed gene interaction networks using STRING (https://string-db.org/).Results: We detected 2 of 3 microRNAs in the group of patients with cutaneous melanoma: microRNA-205 and microRNA-146a-5p. In both the control group and the group of patients with melanoma, 1 of 3 microRNAs, namely miR-146a-5p, was found. The mean ∆Ct value of microRNA-146a-5p was 3.81±2.03 in the control group and 2.26±1.34 in the patients with melanoma. Due to the wide range of values in the control group and the group of patients with cutaneous melanoma, microRNA-146a-5p cannot be considered an informative biomarker. At the same time, we found high expression of microRNA-205 in the group of patients with cutaneous melanoma.Conclusions: microRNA-205 was found to be valuable in melanoma diagnosis. However, further studies with larger sample size and additional stratification by histopathological features are needed.

Published: February 2025

Abstract
This paper studied basic properties of the S0-like SAW mode on the Al/LiTaO3/SiO₂/SiC structure for its implementation to the resonator. First, it is shown that this configuration offers a large electromechanical coupling factor (keff2) when the propagation direction and the SiO₂ thickness are chosen properly. In addition, the SiO₂ layer provides temperature compensation. Impact of the electrode material and thickness is also discussed. Then, the transverse mode suppression is discussed. The “mixed piston” design, “dielectric strips” design, and the combination of “hammer head” and “dielectric strips” designs are chosen for the discussion. The results indicated that both the “mixed piston” and “dielectric strips” designs can suppress transverse mode resonances effectively. However, the Bode Q degradation occurs near the main resonance when the piston layer thickness is large. Although the combination of “hammer head” and “dielectric strips” designs offers good transverse mode suppression, another resonance peak newly appears below the main resonance.
Learning for All: Exploring the Relationship Between Inclusion and Achievement in a Primary Setting
Authors: Lobo Lindsay , Fisher Katy , Dudgeon Paula 
Published: February 2025

All education practitioners have a responsibility to support the participation and achievement of all children within learning communities – particularly within increasingly diverse societies. Inclusive pedagogy allows an exploration of what education practitioners believe, know and do, alongside the research literature on inclusive approaches to teaching, to support this participation and achievement. By utilising the Framework for Participation (Florian et al., 2017), this research aims to understand how the concepts of inclusion and achievement are constructed within a local primary school recognised as being inclusive of its diverse population. This single-site case study incorporated multiple methods of data collection, within an iterative process, and utilised deductive thematic analysis to draw key themes around what practitioners and the school community believe, know and do. The Framework for Participation allowed for an in-depth socio-cultural exploration of inclusion and achievement, including tensions and contradictions, which are highlighted. Ways in which this research methodology can complement and extend the reflective development of inclusive practices in schools are discussed.

Abstract
The upcoming all-sky infrared spectrophotometric SPHEREx mission is set to provide spatially resolved stellar mass maps of nearby galaxies, offering more detailed insights than integrated light observations. In this study, we develop a strategy for estimating stellar mass using SPHEREx by examining the dependence on different stellar population synthesis (SPS) models and proposing new scaling relations based on simulated SPHEREx data. We estimate the resolved stellar masses of 19 nearby late-type galaxies from the PHANGS-MUSE survey, treating these as fiducial masses. By testing four SPS models covering infrared wavelengths, i.e., E-MILES, Bruzual & Charlot (BC03), Charlot & Bruzual (CB19), and FSPS, we find systematic differences in mass-to-light ratios at 3.6 μm (M
*/L
3.6 μm) among the SPS models. In particular, BC03 and CB19 yield mass-to-light ratios on average ∼0.2−0.3 dex lower than those from E-MILES and FSPS. These mass-to-light ratios strongly correlate with stellar age, indicating a significant impact of young stellar populations on stellar mass measurements. Our analysis, incorporating fiducial masses and simulated SPHEREx data, identifies the 1.6 μm band as the optimal wavelength for stellar mass estimation, with the lowest scatter (0.15−0.20 dex) of the stellar mass. This scatter can be further reduced to 0.10−0.12 dex across all SPS models by incorporating optical and SPHEREx colors. These results can provide guidance for measuring the stellar masses of the numerous nearby galaxies that SPHEREx will survey.
One-dimensional Linear Analysis and Numerical Simulations of Alfvén Waves in a Force-free Magnetosphere around a Kerr Black Hole
Authors: Koide Shinji , Noda Sousuke , Takahashi Masaaki 
Published: February 2025

Abstract
We perform 1D linear analysis and numerical simulations of the propagation of Alfvén waves in a force-free magnetosphere along magnetic field lines around a spinning black hole. We use the results to investigate the dynamic process of wave propagation and energy transport for Alfvén waves. As in a previous study using the Banados–Teitelboim–Zanelli spacetime, the Alfvén wave induces a fast magnetosonic wave in the case of a spinning black hole. Energy conservation is confirmed when this additional induced magnetosonic wave is considered. We also observe the reflection of the inwardly propagating Alfvén wave around the static limit, which is prohibited in theory when using the eikonal approximation.
