Introduction and aim. To investigate the relationship between the consumption of traditional Turkish brewing style coffee and other brewing style coffee and hemoglobin A1c:glycated hemoglobin (HbA1c) levels in patients with type-2 diabetes mellitus.
Material and methods. One hundred fifty patients were included in the study. The research sample was obtained from a family health center that called İzmir Karşıyaka 16 -Family Health Center in İzmir-Türkiye. Sociodemographic characteristics, medications, diet, nutritional status, self-reported health status, and consumption of Turkish and other coffee consumption style and other beverages of the patients were recorded. HbA1c, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride, total cholesterol, and fasting plasma glucose levels in the previous year were obtained from medical records. All patients had their HbA1c readings taken on quarterly basis. In addition, routine blood tests, including HbA1c measurements, were conducted every six months as part of the regular follow up at the family health center. The International Physical Activity Questionnaire (IPAQ) was used to evaluate the daily physical activities of the patients.
Results. The median HbA1c value of the group taking oral antidiabetic drugs was significantly lower than the median HbA1c value of the group using insulin (p=0.012). There was no significant difference in HbA1c levels regarding missing a meal, drinking coffee (sugar-free or not), and physical activity (p>0.05). Correlation analysis showed a significant weak relationship between the amount of Turkish coffee consumption per week and fasting blood glucose level (p=0.041, r=-0.088). There was a negative weak and significant relationship (p<0.05) between HbA1c levels and the amount of Turkish coffee consumption per week (p=0.014). In the exponential regression model, coffee consumption per week explained the HbA1c level in proportion to 2.9% (F=4.386; p=0.038).
Conclusion. Consumption of Turkish coffee was inversely correlated with fasting glucose and HbA1c levels. Future studies are needed to determine the effect of coffee in the treatment of diabetes mellitus.

Introduction and aim. The use of modern bioceramic materials has enhanced the predictability of vital pulp therapy. This study aimed to assess the clinical success of Biodentine, modified NeoPutty mineral trioxide aggregate (MTA), and calcium hydroxide Ca(OH)2 as pulp capping materials for indirect pulp capping in carious primary teeth.
Material and methods. Indirect pulp treatment (IPT) was performed on 36 deciduous molars in 36 patients who were presented with deep carious lesions. The teeth were randomly assigned to three groups: Biodentine (12 teeth), modified NeoPuttyMTA (12 teeth), and Ca(OH)2 (12 teeth).
Results. A statistical analysis was conducted using SPSS software version 21.0. Pearson’s Chi-square test was employed to compare success and failure rates among Biodentine, modified Neoputty MTA, and Ca(OH)2 at three different time intervals (30, 90, and 180 days) and overall success and failure rates regardless of the time intervals. In the statistical analysis, different pulp capping materials yielded varying success rates. The modified NeoPutty MTA group demonstrated a success rate of 91.67%, the Biodentine group 83.33%, and the Ca(OH)2 group 58.33% after 6 months. However, these differences were not statistically significant.
Conclusion. IPT with calcium silicate-based materials, such as Biodentine and modified NeoPutty MTA, showed superior results when compared to the use of calcium hydroxide Ca(OH)2. Although differences in success rates were observed among the materials, they did not reach statistical significance.

Introduction and aim. The high prevalence of childhood undernutrition continues to be a major public health issue in India. This systematic and meta-analysis study employed both the composite index of anthropometric failures (CIAF) and conventional to determine the magnitude of undernutrition in Indian children.
Material and methods. A comprehensive literature search was conducted from 2005 to June 2023 using electronic databases, including Google Scholar, Web of Science, SCOPUS, PubMed, J-Gate, and ScienceDirect. A random-effects model for pooled prevalence rates was generated and heterogeneity was assessed using the I2 index and Q statistics.
Analysis of the literature. CIAF revealed a higher prevalence of undernutrition than conventional anthropometric indices in children aged 0 to 72 months. The combined prevalence of stunting and underweight was 37% (95%CI: 0.32-0.41), and wasting was 22% (95%CI: 0.18-0.25) (p<0.01). However, according to CIAF categorization, the pooled prevalence of undernourishment was reported to be 55% (95% CI:0.50-0.60; p<0.01). CIAF’s higher prevalence highlights its effectiveness in capturing childhood undernutrition, accounting for children with multiple concurrent nutritional deficiencies in population.
Conclusion. This systematic review and meta-analysis investigated the assessment of undernutrition using conventional anthropometric indices compared with CIAF, which aggregate different aspects of undernutrition, especially when children have multiple undernutrition issues. Appropriate, target-specific interventions are necessary to improve the overall nutritional status of Indian children.

Introduction and aim. Baby care training given to mothers can help them feel more secure and make their motherhood role more effective. The aim was to determine the effect of early postnatal infant care training on the maternal role and anxiety in first-time mothers.
Material and methods. The study involved 60 mothers of which n=30 were in a control group with treatment as usual and n=30 were in the intervention group receiving special training on infant feeding, basic hygiene practices, baby’s sleep patterns and basic care skills. Training took place in the first 8 and 24 hours after birth and mothers were followed up 5 weeks later. The “Barkin Maternal Function Inventory (BMFI)” and “Postpartum Anxiety Scale (PAS)” were used to measure maternal roles and postpartum anxiety at 6 weeks after birth.
Results. Participants were usually between 28–32 years of age and were first-time mothers. Six weeks after birth, there was a statistically significant difference in BMFI total scores between the experimental and control groups (p<0.001), while the experimental group scored higher (89.8±11.01). There was no significant difference between the groups in terms of postpartum anxiety.
Conclusion. Significant improvements were observed in the anxiety levels and mothering skills of mothers who received training. It is recommended that similar training programs be implemented on a larger scale and their effects be monitored long-term.

Introduction and aim. Sleep quality is crucial for patient recovery, particularly in critical care settings such as the Intensive Cardiac Care Unit (ICCU). This study aimed to investigate the effectiveness of using eye masks and earplugs in improving sleep quality among ICCU patients.
Material and methods. A quasi-experimental study was conducted using a one-group without control design. A total of 40 ICCU patients were provided with eye masks and earplugs for a minimum duration of three days. Sleep quality was assessed using the Richard Campbell Sleep Questionnaire (RSCQ) before and after the intervention. Data were analyzed using descriptive and inferential statistics.
Results. The use of eye masks and earplugs significantly improved sleep quality among ICCU patients (p<0.05). There was a notable increase in sleep duration, reduction in sleep onset latency, and improvement in sleep efficiency following the intervention. These findings support the efficacy of non-pharmacological interventions in enhancing sleep quality in critical care settings.
Conclusion. The findings highlight the importance of incorporating simple interventions such as eye masks and earplugs into routine care practices in ICCUs to improve patients’ sleep quality.
Archaeological and Anthropological Aspects of the Study of the Pre-Scythian Burials from the Volga-Don Interfluve
Authors: Balabanova Mariya , Dyachenko Alexander
Published: December 2024

Introduction. The paper is devoted to a study of archaeological and anthropological features of the four Pre-Scythian burials from the burial grounds of the Volga-Don interfluves. Material and Methods. In the course of the study, materials from the monuments Marinovka, Kurgan 1, burial 17 have been examined; Pervomaisky VII, kurgan 46, burial 8; Pervomaisky VIII, kurgan 5, burial 1 and Baranovka I, kurgan10, burial 11. In order to evaluate the archaeological context, a typological research method and the results of radiocarbon dating are applied; for the purpose of studying anthropological features, craniological analysis and pathological conditions analysis were conducted. Analysis and Discussion. The study of the funeral rite and the material culture grave goods of the Pre-Scythian period made it possible to attribute the three burials to the so-called “Chernogorovsky type” and one to the “Novocherkassk type”. The dates comparison obtained by the relative chronology method with radiocarbon dating showed some underestimation of the existent burials timing in absolute dates. Individual skulls features revealed heterogeneity of composition which is associated with both the previous Late Bronze Age population from this territory who practiced the crouched position of the deceased in funeral rituals, and with newcomer groups morphologically similar to the population of the Bronze Age of Southern Siberia (Karasuk) who use elongated bones practice in the funeral rite. Furthermore, a series of the skulls pathological features showed their similarity to the population of the Sauromatian-Sarmatian period who practiced nomadic lifestyle. Conclusions: The materials from the monuments of the Volga-Don interfluve described in the paper illustrate the burial traditions similarity and morphological specificity of the Pre-Scythian population from the Northern Black Sea, the Lower Don and the Ciscaucasia regions.
Origin and Attribution of the Items in Eastern European Champlevй Enamels Style (Late 2nd – 4th Centuries) Found South-Eastward of the Main Dnieper Area
Authors: Radyush Oleg
Published: December 2024

This article examines the origin and attribution of ornaments in Eastern European style found to the south and east of the main Dnieper area of such artifacts. Previously unknown artifacts are introduced into scientific circulation. Development of local barbarian jewelry styles in Eastern Europe reached its peak in the late 2nd – mid-3rd centuries AD. Most known enameled finds belong to this time period, although some types of items can be traced back to the late 4th to early 5th centuries. Archaeological finds from closed complexes in the Northwestern Black Sea region, the Crimea, the North Caucasus, and the Lower Don are dated to all stages of the enameled style development. The early stage includes such sites as Bedrazhy Noi and Krasny Mayak, while the middle stage is represented by Valovyi I, Kepy, Chatyr-Dag, Diviziya, Skalistoye (burial 28L), and Neapolis-Scythian. The late stage of development can be attributed to Neyzats (graves 275 and 480). Numerous casual finds in the Crimea area suggest regular connections between the northern forest-steppe and forest territories with the peninsula from early forms to later varieties of enameled items. The article discusses issues of ethno-cultural attribution and distribution of the enameled ornaments. Various theories and hypotheses about the origin of enamels associate them with different ethnic groups and regions. The movement of groups from the Dnieper region eastward through the Central Don and Khoper formed contacts with the local population reaching as far as the Volga region. However, the Caucasian finds, due to their remoteness and specific context, are of particular interest. Military campaigns along the Black Sea coast and the involvement of numerous tribes in those conflicts contributed to the spread of the enamel tradition, as evidenced by finds in the Crimea and the Lower Don region. It is also worth considering various forms of matrimonial contacts, given the fact that many burials were female.
Clan Crypts on the Lower Don of the Early Catacomb Time and Genesis Issues of the Catacomb Rite
Authors: Kiyashko Alexey
Published: December 2024

The article provides comprehensive information about two Middle Bronze Age burials (No. 26, 42) from the kurgan 1 in the burial mound Vesely I near Novocherkassk in the Rostov region. The burials contained double tombs with a complex rite and prestigious accompanying items namely bronze tools and silver jewelry. The analysis of the rite and the inventory of the considered catacombs as well as the stratigraphic data allowed identifying their cultural affiliation and attributing them to two successive stages of the Early Catacomb period on the Lower Don: pre-Donetsk (No. 26) and early Donetsk (No. 42) cultures. The presence of the crypt ritual signs in the first catacomb has become the important discovery. The ritual consists of skulls posthumous displacement at a significant distance from the backbone and probable additional reburial in an existing burial chamber. In the second catacomb dating back to a later period, the collapse of the skull on the chest of the buried individual was identified as unintentional and must have been associated with the skeleton soft tissues decomposition. A combined method for radiocarbon dating using accelerator mass spectrometry (AMS), DNA analysis of the bones as well as the isotope study of the teeth were carried out in the laboratories of Belfast and Harvard. It was established that all the buried individuals were close relatives in the male line. Furthermore, two brothers turned out to be buried in different catacombs No. 26 and 42 at different time. This degree of relationship of the buried allowed clarifying and correcting the radiocarbon dating of their remains. Firstly, the cross-overlap of the dates of close relatives made it possible to cut off the plumes of values related to the error of the method. Secondly, it has become possible to narrow the date range to the interval from the late 30th to the late 29th centuries BC considering the actual age of the brothers buried in different graves (excluding possible freshwater reservoir effect). Taking into account that the studied catacombs were related to different archeological periods, the data indicate an accelerated pace of cultural genesis in the early stages of catacomb culture compared to its developed or later periods.
Methods to establish GIS for planning cost-effective geotechnical site investigations
Authors: Lim Eugene , Moore Nicholas
Published: December 2024

Planning a geotechnical site investigation can be a daunting task especially if the scope of works is substantial. Desk studies of available information and geotechnical risk assessments of proposed designs are challenging because the data must be accessed on different media and formats. This requires constant cross-reference to a multitude of applications and meticulous inferences between them. A significant quantum of ground information contained in large volumes of historical reports are difficult to retrieve and manage, leading to a loss of efficiency and coherence. Reliability of the information for use in scoping and design must be carefully assessed. Developing the scope of works requires site inspections to ascertain the feasibility of test points and to confirm accessibility. Explaining the proposed scope to the client for approval is the most critical task in the process and the current practice does not focus on improving the client’s appreciation for geotechnical risks and their buy-in to the proposed scope. This paper presents novel methods to improve the process of planning site investigations. It is based on the successful use of novel methods, powered by GIS, to plan a geotechnical site investigation for a major highway upgrade project in Queensland, Australia.

Çadır, tarih boyunca göçebe yaşam tarzının bir unsuru olarak insanların konaklama ve korunma ihtiyaçlarına yönelik geliştirdikleri çözümlerin bir ürünü olarak meydana çıkmıştır. Değişik ölçü ve formda tasarlanan çadırlar, göçebe toplulukların gereksinimlerini karşılamak üzere kolayca monte edilebilen, demonte edilebilen ve taşınabilir nitelikte konutlar olarak işlev görmüştür. Bu bağlamda Eski Türk toplulukları için çadır, hayatlarının ayrılmaz bir parçası olup önemli bir rol oynamıştır. Eski Türk toplumlarında olduğu gibi Timurlu döneminde de, çadırlar, toplumun yaşam tarzını, ekonomik durumunu, sosyal ve mimari yapılarını yansıtan önemli bir öğe olarak öne çıkmıştır. Bu nedenle, çadırların iç ve dış tasarımına büyük bir önem verilmiş ve sanatsal yetenekler, mimari yapılarla benzer şekilde çadırlarda da sergilenmiştir. Çadır, Timurlular arasında toplumsal yapının önemli bir unsurunu oluşturarak aileleri bir araya getirmiş ve toplumsal dayanışmayı artırmıştır. Bu dayanışma, Timurluların sosyal bağlarını güçlendirmiş ve bir arada yaşama kültürüne katkıda bulunmuştur. Belirtmek gerekir ki, çadırlar sadece hanedan üyeleri için değil, aynı zamanda toplumun diğer kesimleri için de kurulmuş ve tüm aktivitelerini gerçekleştirmişlerdir. Çalışmamızda, Timurlu dönemi çadırlarının fonksiyonları, mahiyeti ve kullanım alanları detaylı bir şekilde ele alınmış, bu çadırların topluma sağladığı katkılar üzerine değerlendirmeler yapılmıştır. Ayrıca, Timurluların bu çadırları hangi amaçlarla ve nerede kullanıp, toplumun kültürünü nasıl yansıttıkları incelenmiştir. Minyatürler aracılığıyla yapılan analizler, hanedan ile halk tabakasının çadırları hakkında bilgiler sunarak, bu iki grup arasındaki farkları ve benzerlikleri ortaya koymaktadır.

Spinal cord tumors, differing in their histostructure, the nature of growth and the ratio to the diameter of the spinal cord, continue to be a difficult problem, both in terms of choosing the optimal treatment tactics and results. We present the results of surgical treatment of the most common spinal chord neoplasms in 2022, conducted in the Alexandro-Mariinskaya Regional Clinical Hospita. The purpose of the study – to present the results of surgical treat-ment of spinal cord and spine tumors with secondary compression of neural structures that differ in histostructure, de-gree of malignancy and level of lesion. In 2022, 19 patients were operated on by various methods in the Alexandro-Mariinskaya Regional Clinical Hospita. 3 clinical cases with different histostructure and topographic-anatomical level of lesion are presented. Surgical treatment of spinal cord tumors was performed in 19 patients with different histostruc-ture and topographic and anatomical lesion levels. Using the example of three clinical cases, the choice of various sur-gical treatment tactics that are most optimal for maintaining the patient's quality of life is demonstrated. The analysis of the surgical manual, its relationship with the prognostic trend, which affect the overall survival of patients with tu-mors of the spinal cord and spine. The dependence of a number of factors was revealed: the histological structure, the degree of “aggressiveness” of the oncological process, the possible spread of metastatic foci in the body. This, in turn, is interconnected with modern methods of diagnosis, surgical and adjuvant treatment, neurological and somatic compen-sation of the patient, which will allow to determine and transfer the aggressiveness of the indicated treatment method. The available modern equipment, accumulated surgical experience and the chosen active tactics for the maximum total removal of the lesion justified themselves, allowing to achieve a good functional result in 18 of the 19 operated patients.

Published: December 2024

Introduction: the article outlines directions, developed from an earlier assessment,
aimed at strengthening the role of large corporations in the revenues of the budget system
based on the case of ferrous metallurgy and chemical industries. Objectives: to develop and justify
measures to increase the role of large corporations in generating revenues of the Russian
Federation budget system. Methods: literature analysis, comparison and generalization
method, index method, factor analysis, specific gravity and dynamic data analysis. Results:
the assessment of the financial interaction of ferrous metallurgy and chemical industry
corporations with the state carried out in previous studies revealed a high potential of large
industry corporations to the formation of regional budget revenues by income tax deductions.
At the same time, companies are characterized by a large amount of VAT reimbursed
from the budget for export operations, which can reach 15–20 billion rubles per year,
which significantly reduces the contribution of companies to the formation of federal budget
revenues. Despite the growth in income tax, personal income tax and property tax revenues,
which is associated with favorable market conditions, corporations are characterized by a many
times greater increase in dividend payments to key shareholders and an increase in the share
of net profit payments. To strengthen the role of large corporations in national development
and the budgetary system, measures were proposing, such as partial reimbursement of export
VAT, the development of special administrative regions and incentives for corporations
to register in them, as well as tax deduction for dividends provided these are used for socially
oriented activities and business expansion. Conclusions: the measures proposed in the course
of the study will increase tax revenues from large corporations to the budget system, stimulate
their transition to Russian jurisdiction, and also encourage them to actively invest monetary
resources into socio-economic development of both home regions and charity, as well
as into the development of infrastructure in special administrative regions.

Preparation of design technical documentation for the development of hydrocarbon deposits includes many processes, the implementation of which is determined by the requirements of current regulatory documents. Processing a large amount of information, reducing the time frame for the execution of design documents and increasing requirements for the completeness and quality of its content poses the task of automating design processes for specialized institutes.The article considers the process of digital transformation in the field of designing the development of oil and gas fields using the example of the science-intensive software «AutoPTD», developed by PJSC NK Rosneft within the framework of the target innovative project «Smart-GIR». The key principles and components of the system aimed at automating the process of creating design and technical documentation are described. Particular attention is paid to the creation of a single digital space, automation of labor-intensive tasks, ensuring end-to-end use of data and unification of approaches to calculations.The development and implementation of this software will allow the transition to a single digital space, providing for the work of the design team in separate modules of «AutoPTD» using a single source of information. When changing any parameter in one module, automatic synchronization and updating of data in all other modules is provided. This will minimize the risk of errors, eliminate duplication of information, improve work efficiency and the quality of design documents. As a result of using a single digital database, it is planned to obtain digital transparency of the system, unify and automate the processes of generating design documents.To control the process of preparing technical design documents, a business process control module has already been implemented and is used. This allows monitoring the current state of the design process and tracking project deadlines.The article presents the target state of the implementation of the «AutoPTD» software, as well as the current results of its development.Automation of the process of preparing design and technical documents through the use of «AutoPTD» modules will increase the speed of work and at the same time improve the quality of projects by reducing the risk of errors.
ON THE EFFECT OF CAPILLARY FORCES ON PULSE DYNAMICS IN A POROUS MEDIUM
Authors: Gimaltdinov I.K. , Rodionov A.S.
Published: December 2024

The study of elastic waves in porous media is of practical importance for the tasks of mineral prospecting, the use of porous screens for damping shock wave effects, studying the structure of the Earth's crust, etc. The elastic properties of a porous medium depend on the velocity of propagation of elastic waves, which, in turn, strongly depends on the degree of consolidation in the porous medium. The main acoustic feature of bulk sand (sand, glass balls, granular materials) media is the low speed of sound, about 100 m/s. Their compaction leads to a slight increase in velocity, and consolidation (sandstone, cementation with gas hydrate) leads to a multiple increase in the velocity of acoustic waves, about 2000-3000 m/s. In the process of hydraulic fracturing, water–gas exposure, treatment of porous formations with various acids to increase the bottom-hole zone of the formation, during the formation and decomposition of gas hydrates, the porous medium is saturated with a gas-liquid - bubble mixture. The morphology of the arrangement of bubbles and particles forming a porous skeleton can be different: the bubbles can be located in a liquid saturating the pores, cover several particles of the skeleton, or the liquid can be in the form of capillary water located in the form of a meniscus between two particles. To monitor the effectiveness of the above-described effects on porous media, acoustic sounding of porous media saturated with a gas-liquid mixture can be used. Therefore, the purpose of this work is to simulate the process of passing shock waves of small amplitude in sand saturated with liquid. The effect of the capillary coupling force on the dynamics of a shock wave pulse in a partially liquid–saturated porous medium is analyzed. A system of equations of mechanics of multiphase media is used for mathematical modeling, including the equation of conservation of mass for gas and solid phase, the equation of pulses and the equation of energy. The skeleton of a porous medium is assumed to be viscoelastic, the gas is calorically perfect; the forces of capillary adhesion between the grains of sand, the forces of viscous friction and the attached masses are taken into account. The control volume method is used for the numerical solution of the presented model.
MODELLING RATE OF PENETRATION AND WEAR OF PDC BITS
Authors: Dzhafarov R.F. , Dadashev M.N.
Published: December 2024

Development of mathematical models for calculation of the Rate of Penetration (ROP) including prediction of bit wear is typically fulfilled by collection and processing data obtained during numerous laboratory experiments. Such models cover influence of a small set of geological factors, some of which cannot be measured under bottomhole conditions or require additional expensive operations. Besides that, cost of PDC bits is considerably higher than of roller-cone ones necessitating the search for more efficient solutions in order to model their behavior.Abovementioned reasons lead to that performance of traditional mathematical models for ROP prediction significantly diminishes while testing under field conditions. The latter, in turn, prevents their widespread use in practice for tackling a number of problems such as optimization of the drilling regime parameters, selection of the best of competing bits, estimation of the recommended bit operating time, determination of the bit lift moment for further replacement, and etc.In the current article, an alternative approach is considered based on the neural networks and embeddings which allows modelling a PDC bit condition and the impact of geological factors through hidden features. The distinctive characteristics in this case are the high adaptability of the model to specific well drilling conditions, as well as the ability to take into account an unlimited number of parameters that affect the process.Reliability of the research results was estimated both qualitatively and quantitatively. The nature of the calculated ROP change corresponds to the actual one. The statistical indicators of the mathematical model performance based on the trained neural network also demonstrate a high convergence of the calculated data with the actual ones. In particular, the determination coefficient exceeds 0.80.Based on the results of the conducted research, it was possible to establish previously unknown features of PDC bits; to develop new equations describing the relationship of ROP as well as a bit wear on its progress while drilling under constant geological and technological conditions.

When interpreting pressure curves in various software packages, the initial reservoir pressure is determined before a given production history. Formation pressure dynamics can be determined only with completely closed formation boundaries. At the same time, changing the operating modes of neighboring wells leads to a change in reservoir pressure in the drainage area of the studied well for long-term pressure records. In this regard, there is a need to calculate not only the initial, but also later reservoir pressures in the absence of closed reservoir boundaries.To solve this problem, two methods have been proposed for estimating reservoir pressure from long pressure and flow rate curves for any type of boundaries and reservoir:— by dividing the curve into sections with different skin factors, further recalculating the change in skin difference to the change in reservoir pressure (does not work for closed borders);— by recalculation through the calculated well productivity.The first method is recommended to be used for unsteady modes, the second — when pseudo-steady modes are reached.Approbation for 19 wells confirmed that the main criterion for the applicability of both methods is the relative constancy of productivity and properties of the bottomhole zone of the formation, i.e. the absence of winder, pilot injection, hydraulic fracturing, etc., in the studied area of the time, the absence of a multiple change in production rate when changing operating modes, there are also another number of restrictions, such as the presence of an individual means of measuring production rate on the well (SKZ or one lug per GZU) and the use of only one measuring instrument, the duration of the time between the measured and calculated reservoir pressures is not recommended for more than six months, wells with SHSNU are not recommended for calculations, due to the long time to reach the mode, but if there are GIK records and compliance with the main criteria, formation pressure can be estimated.These methods are auxiliary and do not replace real formation pressure measurements.

The energy thresholds of initiation and kinetic characteristics of the explosive decomposition process of heavy metal azides (НМА), pentaerythrite tetranitrate (PETN), and furazanotetrazindioxide (FTDO) were measured at various wavelengths and the impacting pulse durations of ~ 10-20 ns. It is established that the behavior of energy materials changes significantly when initiated under the open and closed surface conditions, which is associated with the peculiarities of the gas-dynamic unloading of thermal microfoci.

The parameters have been determined of the resonator consisting of two dielectric plates with gratings of strip conductors in the form of squares between the layers and in the form of square gratings, having the same subwavelength period, on the outer surfaces. The quality factor of the resonator, measured at normal wave incidence, is determined by the ratio of the widths of the internal and external conductors. Using electrodynamic analysis of a 3D resonator model, the propagation of plane linearly polarized electromagnetic waves was studied in case when their angle of incidence φ deviates from the normal to the plane of the layered structure. It was found that for the parallel polarization of the wave, the quality factor of the observed half-wave resonance first drops with increasing φ to a minimum when approaching the Brewster angle, and then, it increases at φ → 90°. In case of the perpendicular polarization of the wave, the quality factor of the half-wave resonance constantly increases with increasing φ, approaching the maximum value at φ → 90°.

The results of a study of methods for measuring the divergence of radiation in THL-100 laser system by the distribution of its intensity in far field are presented. Attention is drawn to the problems of recording parameters of a beam with a large diameter (up to 200 mm) in air associated with the distortion of the wave front on the air inhomogeneities. Different optical schemes for focusing beams with different diameters are studied. It is shown that the best results are achieved only when the beam diameter is reduced to 90 mm, when it becomes possible to record the radiation divergence close to the diffraction limit of 1.5Qd.

Published: December 2024

Based on the expression obtained using a labeled graph of states of donor-acceptor pairs, a simple analytical relationship has been established between the stationary population of the triplet T 1-state of acceptor molecules and the multiples of changes in donor photoexcitation intensities and sensitized phosphorescence of the acceptor, similar to that obtained previously for a one-component solution. The calculated values of the relative stationary population qT of the T 1-state of the acceptor pair benzophenone (donor) - acenaphthene (acceptor) are in good agreement with the results obtained by the well-known method based on the times of rise and decay of sensitized phosphorescence. The limitations of using the proposed method are indicated.

The results of a study of the characteristics of low-cost compact vector network analyzers in the frequency range from 100 kHz to 3-6 GHz are presented. Using these instruments, measurements of the complex permittivity of soils and solid dielectric sawdust were carried out. These data were compared with the results of measurement using the ZNB20 vector network analyzer. It is shown that at frequencies above 100 MHz, scattering of experimental points relative to the ZNB20 measurement line is observed. This drawback can be partially eliminated by modeling the frequency spectra of the complex permittivity.
