Investigating the cardiovascular effects of natural compounds, such as linalool, has aroused interest due to the potential impact on cardiovascular health. Linalool, a component present in several essential oils, has demonstrated promising pharmacological properties, including antihypertensive activity. However, its bioavailability and efficacy can be influenced by complexation with β-cyclodextrin, a strategy frequently used to improve the solubility and stability of bioactive substances. This study aimed to carry out a systematic review of the literature, exploring the cardiovascular effects of free linalool and linalool complexed with β-cyclodextrin. Objective: To investigate the cardiovascular effects of free linalool and linalool complexed with β-cyclodextrin, with emphasis on the antihypertensive action, through a systematic review of the literature. Methodology: The review was conducted according to PRISMA guidelines. The PubMed, Scielo and Web of Science databases were consulted, using the descriptors "linalool", "β-cyclodextrin", "cardiovascular effects", "antihypertensive" and "complexation". The inclusion criteria covered studies published in the last 10 years, focusing on in vivo experiments, clinical trials and systematic reviews. Articles unrelated to the topic, duplicate studies and those without peer review were excluded. Results: They revealed that linalool, when complexed with β-cyclodextrin, presented greater bioavailability and stability, enhancing its antihypertensive action. In vivo studies have demonstrated a significant reduction in blood pressure in hypertensive animal models. Furthermore, the complexation positively influenced the gastrointestinal absorption of linalool. These findings suggest that the complexed formulation may represent an effective approach to improving the cardiovascular effects of linalool. Conclusion: The systematic review highlights the relevance of complexing linalool to β-cyclodextrin as a strategy to enhance its antihypertensive effects. Understanding these mechanisms can contribute to the development of more effective pharmaceutical formulations in the management of hypertension, promoting advances in cardiovascular therapy.

Предложено решение задачи поиска и обнаружения каналов экстремистской направленности в наиболее популярном мессенджере Telegram. Разработан метод, основанный на использовании глубоких искусственных нейронных сетей BERT в качестве классификатора текстов. На его основе разработана программа, позволяющая в автоматизированном режиме осуществлять анализ телеграмм-каналов и выявлять материалы экстремистского характера. Описаны пять этапов разработки программы «просеивания» каналов: формирование текстовых корпусов для обучения BERT; выбор архитектуры BERT и обучение классификатора; выгрузка сообщений из анализируемых каналов; оценка наличия экстремизма в сообщениях; оценка каналов на экстремизм. Для апробации метода и программного продукта проведена серия экспериментов, в ходе которых осуществлен мониторинг 68 каналов по 8 категориям с целью их «просеивания» на наличие экстремистского контента. По результатам экспериментов ранжированы телеграмм-каналы, распространяющие экстремистские материалы. Оценена доля сообщений экстремистского характера в каждой категории каналов. Сделан вывод, что представленный подход к «просеиванию» телеграмм-каналов на наличие экстремистских сообщений целесообразно использовать в работе государственных структур, занимающихся выявлением и мониторингом распространения противоправной информации.

A solution to the problem of searching and detecting extremist channels in the most popular Telegram messenger is proposed. A method based on the use of deep artificial neural networks BERT as a classifier of texts has been developed. Based on it, a program has been developed that allows automated analysis of telegram channels and identification of extremist materials. Five stages of the development of the channel "sifting" program are described: the formation of text corpora for BERT training; the choice of the BERT architecture and the training of the classifier; unloading messages from analyzed channels; assessing the presence of extremism in messages; evaluating channels for extremism. To test the method and the software product, a series of experiments were conducted, during which 68 channels were monitored in 8 categories in order to "sift" them for the presence of extremist content. According to the results of the experiments, telegram channels disseminating extremist materials were ranked. The share of extremist messages in each category of channels is estimated. It is concluded that the presented approach to "sifting" telegram channels for the presence of extremist messages is advisable to use in the work of state structures engaged in identifying and monitoring the dissemination of illegal information.

Шумоочистка играет важную роль при оценке эффективности защиты объектов от несанкционированного доступа к речевой информации по оптико-электронным каналам. В работе оценивается эффективность использования шумоочистки речевых сигналов на основе применения вейвлет-анализа. Качество речевой информации, полученной по оптико-электронным каналам несанкционированного доступа, как правило, очень низкое, поэтому вопросы шумоочистки для этих каналов весьма актуальны. Приведено описание таких каналов. Экспериментальная проверка возможности применения вейвлет-анализа для шумоочистки речевых сигналов проведена с помощью лабораторной установки, которая предназначена для физического моделирования аппаратуры регистрации лазерного излучения, отраженного от поверхности, вибрирующей под воздействием речевого акустического сигнала. Показано, что применение вейвлет-анализа для шумоочистки сигналов позволяет существенно повысить эффективность оптико-электронных каналов несанкционированного доступа к речевой информации.

THE EVOLUTION OF INFORMATION SECURITY – FROM DATA AND INFORMATION PROTECTION TO KNOWLEDGE PROTECTION – SCIENTOMETRIC ASPECTS (PART I)
Authors: Филяк П.Ю.
Published: February 2024

В настоящее время проблема обеспечения информационной безопасности становится все более актуальной, что обусловлено, с одной стороны, лавинообразным нарастанием угроз и вызовов в информационной сфере в условиях современности, а с другой, - увеличением количества генерируемой и обрабатываемой информации, в экспоненциальной зависимости. Исходя из позиций технических возможностей, кадровой квалификационной обеспеченности, человеческих ресурсов и экономических аспектов защиты информации становится очевидным, что при полном сохранении существующих подходов к защите информации и обеспечению информационной безопасности, система уравнений обеспечения и существования информационной безопасности (ИБ) может оказаться не совместной. В сложившихся условиях предлагается подход к обеспечению информационной безопасности с позиций концепции знаний, то есть необходим переход от защиты данных и информации к защите самой ценной составляющей – знаний. В статье представлены концептуальные положения такой трансформации подходов к обеспечению ИБ и, как один из возможных вариантов оценки ценности информации и знаний предлагается использование такой области науковедения, как наукометрия.

Currently, the problem of ensuring information security is becoming more and more urgent, which is due, on the one hand, to an avalanche-like increase in threats and challenges in the information sphere in modern conditions, and on the other, to an increase in the amount of information generated and processed, exponentially. Based on the positions of technical capabilities, personnel qualifications, human resources and economic aspects of information protection, it becomes obvious that with the full preservation of existing approaches to information protection and information security, the system of equations for ensuring and maintaining information security (IS) may not be compatible. Under the current conditions, an approach to information security is proposed from the standpoint of the concept of knowledge, that is, a transition from data and information protection to the protection of the most valuable component – knowledge. The article presents the conceptual provisions of such a transformation of approaches to information security and, as one of the possible options for assessing the value of information and knowledge, the use of such a field of science as scientometry is proposed.

Refinement of the gear ratios of the vehicle transmission
Authors:   Dyakov I.F. Moiseev YU.V.
Published: February 2024

A method is proposed to refine the transmission ratios of vehicles by matching the load modes of movement with the design parameters of the transmission, providing optimal speed and the ability to overcome road resistance. Overcoming the emerging forces of resistance to movement is considered from the conditions of energy consumption of the vehicle. To determine the main patterns that characterize the movement of the vehicle, the ratios of traction-dynamic properties were obtained according to the refined parameters of the transmission. The parameters showed some approximation to the existing values of the transmission, thereby ensuring the maximum speed and minimum fuel consumption of the vehicle.
Keywords:vehicles, energy losses, longitudinal force of resistance to movement, torsional rigidity, transmission, dissipative moment, gear ratio.

Published: February 2024

Borehole pumping rods used in the process of oil production in accordance with their functional purpose, are operated in harsh conditions, in particular, they are exposed to dynamic forces, aggressiveness of the corrosive environment, various types of deformations and others. As a result, the probability of breakage of rods and equipment falling to the bottom of the well increases, the level of oil production decreases with an increase in the intensity of repair and restoration work. One of the most promising methods for improving the performance of pumping rods is the treatment of their working surface with high frequency current (HFC). The article reflects the results of the research in the direction of constructive improvement of the device for heat treatment of borehole pumping rods. Keywords. Borehole pumping rods, high frequency current, hardness, cleaning limit, inductor, heat treatment.

New schemes for connecting oscillators as a part of plasma ignition systems for gas turbine engines
Authors:   Gizatullin F.A. Gabidullina Z.G.
Published: February 2024

The effectiveness of new schemes for connecting of oscillators in plasma ignition systems of gas turbine engines is analyzed. The most efficient scheme for connecting an oscillator to reduce losses in the power circuit of the ignition system with an increased igniting ability of the plasmatron is determined. In the plasma torch, there are two types of discharges — continuous arc and pulsed capacitive, while the instantaneous power of a capacitive discharge of short duration is several orders of magnitude higher than the instantaneous power of the arc discharge. The dynamics of discharge processes in the oscillator is estimated. Analytical expressions are presented for the main parameters of pulsed discharges: maximum discharge current, energy and duration of discharges.
