Published: January 2025

Relevance. In the current international situation, despite augmenting threats to data security in the Russian Federation, the procedures granting access to classified information to the authorized military have not undergone any significant changes so far. The existing approaches and methods of selecting professionals to be authorized to access national security information (NSI) fail to consider the candidates’ personal profiles.The study objective is to development of a set of methods allowing to assess and predict individual reliability of military professionals dealing with information security.Methods. The Automated System for Psychophysiological Diagnostics of Addictive Behavior was used; it comprises 2 psychological questionnaires and 2 psychophysiological methods to assess individual reliability in 78 military professionals. Psychophysiological assessment is supplemented with stimuli relevant for data security. The examination required 15 to 20 minutes per each subject, including explanations and practice. To ensure that individual reliability assessment was of an expert level and unbiased, the professors and commanders were asked to complete a dedicated questionnaire per each subject. The results were analyzed using Statistica 12.0 software package.Results and analysis. Once the subjects of various individual reliability scores completed all he automated assessments, the obtained database underwent a discriminant analysis. Eventually, a statistically significant model (p < 0.001) was developed per every subject to predict their personal reliability level. The model sensitivity was is 85.7 %, while the specificity was 100 %. The study identified the most significant psychophysiological markers of low reliability risk in students of higher military education institutions of the Ministry of Defense of the Russian Federation.Conclusion. The developed automated system for individual reliability assessment in data security is registered in the Rospatent Computer Software Register under N 2024663045 dated 03.06.2024 as the “Automated System for Individual Reliability Assessment among the Military Having Access to National Security Information”. Unlike other well-known methods to identify the risk of data protection offences, the proposed tool is user-friendly and eliminates such types of bias, as distorted interpretation of results, investigator’s proficiency and experience, or the pursuit of the subject to provide socially favorable replies.

Authors: Loktionov P. V. , Gudz’ Yu. V. , Vetoshkin A. A. 
Published: January 2025

Relevance. Proximal humerus fractures constitute 5 to 6% of all fractures in adults and are the third most common osteoporotic fracture. Advanced surgical techniques, accumulated knowledge and practical experience, as well as new evolving implants have expanded the indications for surgical treatment. Dedicated studies, however, fail to outline any superior and convincingly outperforming surgical treatment option.The objective is to find out most optimal treatment options by comparing the results in patients with proximal humerus fractures who underwent either blocked intramedullary osteosynthesis (BIOS) or osteosynthesis with precontoured angular stable LCP humerus plates (LCP).Methods. The study included 534 patients with proximal humerus fractures who underwent surgical reconstruction between 2015 and 2024, including 503 (94.2%) patients undergoing BIOS and 31 (5.8%) patients undergoing open LCP repositioning.Results and discussion. The treatment results were assessed in 173 (32.4 %) patients. The postoperative follow-up did not exceed 8 months. BIOS technique allowed to achieve favorable results in terms of absence of pain, restored joint function and scope of movement, as well as low re-operation rate. LCP osteosynthesis showed a slightly poorer performance for all the studies parameters.Conclusion. Blocked intramedullary osteosynthesis is a safe and efficient treatment option in proximal humerus fractures, associated with reliable stabilization, minimized tissue trauma, intact blood supply, low risk of postoperative wound infection, decreased operation time, and early rehabilitation without complications. However, the use of intramedullary pins is not a ‘one-size-fit-all’ treatment strategy. The treatment decision should be supported by advanced diagnostics, taking into account the type of fracture, bone tissue quality and concomitant pathologies, as well as patient’s individual characteristics and expectations.

Relevance. Currently, cholera poses a serious external infection risk for the Russia. Any region of Russia is at risk of cholera infestation/importation, while importation events shall be considered as a real threat to the sanitary and epidemiological wellbeing of the population. Every Russian region is characterized by a set of individual factors and conditions affecting cholera infection risks, as well as preparedness of medical and testing lab capacities. In such environment, every region of Russia is in critical need of region-specific stochastic epidemiological forecasting is critically demanded in the case of cholera infestation importation. Ability to select a most efficient rapid response strategy in every forecasted scenario is no less relevant.The study objective is to use the developed epidemiological risk assessment score for cholera infestation/importation in individual regions of Russia to eventually establish the probability for each of the three potential epidemiological scenarios, as well as to guide scenario-specific rapid response strategies.Methodology. Epidemic risk assessment score for cholera infestation/importation in Russia was developed based on region-specific quantitative evaluation of the potential epidemiological risk at public mass events and the overall epidemiological capacity in case of cholera exposure. Modifications included ranking the sets of assessment score indicators by cholera epidemiological risk exposure with a few extra sets of indicators, such as region-specific product output, economic factors, emergency incidence rate and scope of consequences. Stochastic scenarios are based on retrospective data analyzing the links between the initial epidemiological risk factors, preparedness of medical and laboratory services, and real country specific data regarding the development of the epidemiological situation amid cholera outbreaks.Results and discussion. The study develops a region-specific epidemiological risk assessment score for cholera infestation/importation for Russian Federation regions to provide an insight into the impacts of epidemiological risk factors and counter-epidemic preparedness capacities of every region, considering the implementation of each of the three potential epidemiological situation scenarios (negative, limited spreading, and favorable). The paper elaborates strategies and solutions to provide efficient rapid response in case of either scenario.Conclusion. The developed epidemiological risk assessment score for cholera infestation/importation in individual regions of Russia allows to evaluate the probability for each of the three epidemiological scenarios in a particular region depending on the total score, as well as to select most efficient scenario-specific rapid response strategies.

Authors: Ильясов Д.С. , Ильясов С.Г. 
Published: January 2025

Комплексные соединения, полученные на основе карбогидразида и переходных металлов периодической системы элементов (Ni2+, Zn2+) с динитразовой кислотой являются высокоазотистыми веществами, содержащими активный кислород, и проявляющими свойства энергетических компонентов топлив и составов. Кинетическими исследованиями (методом Остромысленского – Жоба) показано, что [Co(N(NO2)2)2] вступает во взаимодействие с карбогидразидом с образованием в зависимости от мольного соотношения исходных реагентов трех типов комплексов в водном растворе. Экспериментально выделены и идентифицированы физико-химическими методами анализа два типа комплекса, содержащих элементы карбогидразида, кобальта (II) и аниона динитразовой кислоты. Полученные комплексы проявляют свойства высокоэнергетических соединений, обладают хорошей термической стабильностью, но являются небезопасными в обращении, особенно к лучу огня. Методом ИК-спектроскопии показано, что в полученных кобальтовых комплексных солях присутствуют элементы карбогидразида и динитразота, а также взаимосвязь металл-лиганд через атомы N и O карбогидразида.
Complex compounds obtained on the base of carbohydrazide and transition metals of the periodic table of elements (Ni2+, Zn2+) with DNA are highly nitrogenous substances containing active oxygen and exhibiting the properties of energy components of fuels and formulations. Kinetic studies (by the Ostromyslensky – Zhoba method) have shown that [Co(N(NO2)2)2] interacts with carbohydrazide to form, depending on the molar ratio of the initial reagents, three types of complexes in an aqueous solution. Two types of complexes containing elements of carbohydrazide, cobalt (II) and DNA anion has been experimentally isolated and identified by physico-chemical analysis methods. The resulting complexes exhibit the properties of high-energy compounds, have good thermal stability, but are unsafe to handle, especially to a ray of fire. IR spectroscopy has shown that the obtained cobalt complex salts contain elements of carbohydrazide and dinitrazote, as well as the metal-ligand relationship through the N and O carbohydrazide atoms.

Значимость использования труб из композитных материалов при сооружении трубопроводов с каждым годом становится все выше и выше. Несмотря на это статистика показывает, что сталь остается на первом месте в мире по применению в строительстве и будет ведущим строительным материалом еще долгое время. В последние годы заметно сильное увеличение производства стали и стального оборудования по всему миру. Доля производства стали в России для производства труб остается высокой и составляет около четверти от общего объема внутреннего потребления. Российская трубная промышленность за последние десятилетия стала одним из мировых лидеров по уровню технологий и качеству, выпуская широкий ассортимент труб из различных видов стали. Можно сделать вывод, что сталь достаточно долговечна при необходимых условиях. Она выдерживает многочисленное количество нагрузок, почти не испытывая деформаций даже при сильных нагружениях. Исследование направлено на сравнение основных эксплуатационных характеристик и оценку эффективности и перспективности использования композитных материалов в области трубопроводного транспорта. Главным фактором, негативно воздействующим на состояние внутри промысловых трубопроводов при транспортировке нефтяной эмульсии, является проблема коррозии внутри труб. Однако, использование трубопроводов из композитных материалов позволяет решить эту проблему и становится все более актуальной темой. На данный момент в Российской Федерации пока еще не хватает необходимой информации о эксплуатации таких многослойных конструкций, это затрудняет широкое внедрение в проекты и строительство трубопроводов с использованием композитных материалов в нашей стране.
The study is aimed at comparing the main performance characteristics and assessing the effectiveness and prospects of using composite materials in the field of pipeline transport. The main factor that negatively affects the condition of in-field pipelines when transporting oil emulsion is the problem of corrosion inside the pipes. However, the use of pipelines made of composite materials allows us to solve this problem and is becoming an increasingly pressing topic. At the moment, the Russian Federation still lacks the necessary information on the operation, design and construction of such structures, which makes it difficult to widely introduce this technology in our country.

Обосновывается актуальность разработки метода расчёта постоянной Маделунга, принимающего в качестве исходных данных матричные описания, полученные с помощью модифицированного компактного векторно-матричного метода описания. Рассматривается ряд особенностей компактных матричных описаний. Предлагается новая модификация метода Харрисона. Анализируются её сильные и слабые стороны.
The article discusses methods of mathematical description of regular spatial structures. As well as methods for numerical calculation of the Madelung constant. In particular, the methods of Evien and Ewald. Harrison's method, based on the idea of expanding cubes, is considered in more detail. Its modifications are also being considered. It is noted that this calculation method is adapted to the use of compact matrix descriptions as initial data for calculation. The relevance of the development of a method for calculating the Madelung constant, which takes as initial data matrix descriptions obtained using a modified compact vector-matrix description method, is substantiated. A number of features of compact matrix descriptions are considered. A new modification of the Harrison method is proposed. Its strengths and weaknesses are analyzed.

В настоящей работе представлены результаты исследований генерации лазера на композитном элементе из Nd3+:YAG/Cr4+:YAG керамики отечественного производства. Композитный элемент, полученный методом реактивного спекания смеси порошков оксидов, состоит из двух частей – активной среды Nd3+:YAG и пассивного лазерного затвора Cr4+:YAG. В режиме пассивной модуляции добротности реализована генерация излучения со средней мощностью 4,2 Вт. При этом длительность и частота следования импульсов составили 4,6 нс и 68,5 кГц соответственно. С использованием исследуемого лазера в работе реализован процесс взаимодействия лазерного излучения с материалом из нержавеющей стали марки AISI 304 в воздушной и в жидкостной средах. В результате лазерного воздействия на поверхности материала образуются кратеры, а жидкость содержит синтезируемые микро- наночастцы. Таким образом, в работе впервые экспериментально продемонстрирована возможность использования лазера на Nd3+:YAG/Cr4+:YAG керамике для обработки поверхности материала и получения наноразмерных частиц на примере абляции нержавеющей стали AISI 304 в жидкости. Полученные в работе результаты могут быть интересны для решения задач технологической микрообработки материалов и получения частиц различной дисперстности.
This paper presents the results of studying laser generation on a domestically produced composite element made of Nd3+:YAG/Cr4+:YAG ceramics. The composite element obtained by reactive sintering of a mixture of oxide powders consists of two parts – an Nd3+:YAG active medium and a Cr4+:YAG passive laser shutter. In the passive Q-switching mode, generation of radiation with an average power of 4.2 W was realized. The pulse duration and repetition rate were 4.6 ns and 68.5 kHz, respectively. Using the laser under study, the process of interaction of laser radiation with AISI 304 stainless steel in air and liquid environments was realized in the work. As a result of laser action, craters are formed on the surface of the material, and the liquid contains synthesized micro- and nanoparticles. Thus, the work has experimentally demonstrated for the first time the possibility of using a laser on Nd3+:YAG/Cr4+:YAG ceramics for processing the surface of a material and obtaining nanosized particles using the example of ablation of AISI 304 stainless steel in liquid. The results obtained in the work may be of interest for solving problems of technological microprocessing of materials and obtaining particles of various dispersions.
