The authors of the article conduct research on the use of unmanned aircraft systems in various fields and sectors of the economy. The development of unmanned aircraft systems is receiving increased attention. In January 2024, the Russian Federation launched a new national project “Unmanned Aircraft Systems”, which proves the importance of research in this direction. The national project contains a developed strategy for the development of an unmanned aircraft system for the period up to 2030-2035, and it determined the creation of a promising industry for the development of civil drones. Based on the results of the study, it concluded that UAS are actively use to solve issues related to economic, social and environmental and other civil problems. However, at the same time, the authors of the article highlight a number of problems that require theoretical and practical solutions. Issues related to the legal regulation of the use of unmanned aircraft systems remain unresolved. There are also virtually no studies assessing the effectiveness of using unmanned aircraft systems in areas and sectors of the economy. A separate task is to study issues of generating demand and stimulating supply for the development and implementation of unmanned aircraft systems. More research should be conduct to develop solutions to problematic issues.

In 2023, the degree of concern about the use of money and prices turned out to be unusually high both at the level of subjects of economic practice and the population of Russia. The conditions and current trends of the impossibility of a systematic and stable adjustment of the economy to effective growth and development were actually formed. In such a situation, in the process of using money by the population (consumers), guidelines of distrustful expectations for purchases of goods and prices changing on them have developed. The reaction of economic distrust of the stable purchasing power of money was overwhelmed by continuous doubts, an unconvincing perception of the norms and rules of regulation of monetary circulation, and the acuteness of the perception of the inflationary component became a threatening semantic load. All these issues naturally require additional reflection and clarification, interpretation from the point of view of the causes, the formation of factors affecting the authenticity of the measures taken, methods and methods of regulation by the state. Without a deep meaningful understanding of the ongoing processes, this is hardly possible.

Published: April 2024

Damage to forest stands and their death as a result of outbreaks of destructive insects and diseases occur over significant areas and represent an important forestry problem. To solve this problem, it is advisable to use materials from remote sensing of the Earth, since damaged and dead forests can occupy significant areas, from remote еach other. The article presents a methodology for assessing the state of forest stands and the impact of forest pests and diseases on them based on the joint processing of data from a regular grid of sample plots and materials from remote sensing of the Earth via geoinformational technologies, variance and regression analyses. The sample plots have been laid according to the ICPForests methodology and have characterized the general background of the state of the forests in the study area of the North-Western and central parts of the Leningrad Region, where the foci of forest pests and diseases reproduction have been identified at the same time. The applicability of 2 vegetation indices – normalized difference (NDVI) and short–wave (SWVI), as well as the normalized difference moisture index (NDMI), the normalized burn ratio (NBR) and the spectral characteristics of the corresponding channels of the Sentinel-2B image to identify the foci of forest damage by pests and diseases has been assessed. Statistically significant relationships between the state of the stands and the values of the listed indices have been established. It has been shown that the foci of pests and diseases reproduction are reliably detected using the materials from remote sensing of the Earth against the general background of the state of the forests represented by the regular grid of sample plots. A thematic map of the stands has been developed dividing them into 2 groups of state classes: healthy and weakened stands; suppressed stands and deadwood. Its accuracy was assessed via the support vector machine (SVM) on the basis of the combination of ground and remote sensing data. To assess the adequacy of the automatic classification, the error matrix and the calculation of the Cohen’s Kappa coefficient have been used. The coefficient has turned out equal to 0.878, which indicates a high quality of the classification. It has been shown that the developed thematic map is applicable for detecting potential foci of forest pests and diseases reproduction in the study area.
Fiber Cement Soil in the Construction of Pavements for Logging Roads
Authors:   Ural State Forest Engineering University, Chudinov Sergey A.
Published: April 2024

The most important factor in increasing the efficiency of the development of forest tracts is the development and improvement of the transport and operational condition of the network of logging roads. Inert road construction materials, such as sand, crushed stone, crushed stone-sand mixture or gravel-sand mixture, are traditionally used for the construction of pavements for logging roads. However, in the areas with a shortage of these materials, the cost of road construction increases significantly. An alternative technology that can significantly reduce or completely eliminate the use of inert road construction materials is the stabilization of local soils for the construction of pavement structural layers. The soil stabilization technology consists in mixing them with binders and compacting them at the optimal moisture content of the mixture. In doing so, the resulting material acquires the desired strength and frost resistance. The most effective and common binder for soil stabilization is Portland cement. However, along with high strength properties and frost resistance, cement soils, due to their crystalline structure, have low crack resistance, which worsens transport and operational performance and shortens the service life of road pavements. One of the rational solutions for increasing the security of soil stabilization for the construction of road pavements is the installation of fiber cement soil layers. The object of this research is fiber cement soil for the construction of structural layers of road pavements for logging roads. The aim is to improve the physical and mechanical properties and frost resistance of soils stabilized with Portland cement with the addition of the material based on basalt fiber. Laboratory tests of compressive and tensile strength during splitting, as well as frost resistance of fiber cement soils of various compositions were carried out in accordance with GOST R 70452–2022. According to the data obtained, fiber cement soil has higher strength and frost resistance compared to cement soil. The fibers distributed throughout the cement-soil matrix effectively perceive external loads, providing high physical and mechanical indicators, and therefore crack and frost resistance of the material. The use of fiber cement soil for the construction of pavements for logging roads will increase the durability and reliability of their operation, as well as reduce the costs of construction and operation of road transport infrastructure of forest tracts.

The main advantages and peculiarities of the interaction of the links of a logging road train when moving during wood hauling along under-equipped logging roads are considered. Based on the analysis of the results of the research carried out by Russian and foreign authors, promising ways to improve the efficiency of logging trucks with trailers have been identified. The main disadvantages of the existing designs of the devices for coupling logging trucks with trailers have been presented. An improved design of the regenerative pneumohydraulic rod of the coupler of a road train has been proposed, which ensures a reduction in the maximum efforts during the dynamic interaction of the links, an increase in the road train reliability, the possibility of the power fluid energy recovery with its subsequent beneficial use, as well as the effect of self-pulling of the road train, improving its cross-country ability in the conditions of under-equipped logging roads. It has been revealed that the optimal internal diameter of 2 double-acting hydraulic cylinders connected in series with the free ends is within the range of 95 to 105 mm. With such a diameter, the recovered power reaches 4 kW, the average longitudinal acceleration of the trailer is in the range of 0.75 to 0.83 m/s2. The movement of a logging road train in the studied conditions at a speed of 20 to 60 km/h is accompanied by a change in the average recovered power from 1.8 to 11.3 kW and the average longitudinal acceleration of the trailer – from 0.2 to 1.4 m/s2. It has been determined that at average heights of support surface irregularities of 0.1 to 0.2 m, characteristic of typical under-equipped logging roads, the average recovered power is in the range of 2.2 to 4.1 kW and the average longitudinal acceleration of the trailer is in the range of 0.26 to 0.53 m/s2. The optimal stroke of the regenerative pneumohydraulic rod of the coupler of a road train is 0.55 m, the optimal rate of lengthening (or shortening) of the rod is 0.28 m/s. This ensures the average self-pulling speed of 0.22 m/s, the mean displacement of a logging road train of 0.11 m per one cycle of lengthening (or shortening) of the rod and the power recovered by the rod of 1.75 kW.
Wood-Composite Boards with a Low Coefficient of Linear Thermal Expansion

Published: April 2024

A number of industries require materials with a low coefficient of linear thermal expansion (CLTE), in particular, in the production of satellite spherical antennas. The latter are formed from composites containing carbon fibers and synthetic resins. The composition is cured by heating up to 180 °C. This leads to a thermal expansion of the mold and a change in the geometric characteristics of the product. Therefore, specific requirements are imposed on the materials for making molds. The high cost of special materials used for molds determines the need to search for other materials with a low CLTE. Wood is a possible solution to this problem. Its CLTE along the fibers is less than that of the vast majority of materials, and is approximately 3 ‧ 10-6 K–1, which is comparable to special materials. However, the expansion of wood across the fibers is much higher than the longitudinal one, which excludes the use of solid wood. Anisotropy can be reduced by creating a composite in which the fibers are uniformly oriented in all structural directions, bringing the value of wood expansion across the fibers closer to the value of expansion along the fibers. The traditional approach to producing wood composites, based on the use of synthetic adhesives, fails to achieve a noticeable reduction in thermal expansion due to the high CLTE of adhesives The use of boards made of hydrodynamically activated wood particles without binders is promising. Three series of experiments have been carried out: with varying the density of the boards, preliminary thermal modification of the original wood and the use of alkali during hydrodynamic processing. The thermal expansion study has been carried out using the NETZSCH DIL-402 C induction dilatometer in dynamic mode with a heating rate of 2 K/min. It has been established that thermal expansion increases with increasing density.The average CLTE at a density of 950 kg/m3 is 12 ‧10–6 K–1 and at a density of 1,100 kg/m3 it is 17‧10–6 K–1. At a comparable density, the thermal expansion of boards without binders is significantly lower than that of fiberboards (MDF). Preliminary thermal modification of wood does not significantly affect the CLTE of the boards. The use of alkali in the hydrodynamic treatment also has no effect.

The article shows the possibility of intensifying the process of producing microcrystalline cellulose via pregrinding of fibrous semi-finished products before hydrolysis. The technological factors determining the grinding of fibrous materials have been considered. The efficiency of the microcrystalline cellulose production process is influenced by the choice of its production technology. For grinding, a semi-industrial disc mill with a tacking with rectilinear and curvilinear knives has been used. Multiphysics models of the flow of fibrous mass in the grinding zone of a disc mill with different knife tacking patterns have been constructed. The morphological properties of the fiber have been measured on the Morfi Neo automatic fiber analyzer after grinding to 65 °SR. The nature of the change in the properties of bleached sulfate hardwood and softwood cellulose has been analyzed. It has been found that it is identical for all degrees of grinding, but the quantitative characteristics change to the greatest extent when grinding softwood cellulose using a tacking with rectilinear knives: the weighted average length of fibers decreases by 17 %, the width – by 14 %; the content of broken fibers increases by 22 %, the content of fines along the length – by 67 % and the fibrillation index – by 1.9 times. A comparative analysis of the values of the degree of polymerization depending on the knife tacking pattern has been carried out. The conditions for producing microcrystalline cellulose after grinding the fibrous mass in a semi-industrial disc mill, depending on the degree of grinding, have been determined. It has been shown that with an increase in the degree of grinding of the fibrous mass from 15 to 65 °SR, the degree of polymerization of microcrystalline cellulose decreases from 272 to 120, the concentration of hydrochloric acid – from 2.5 to 1.5 N and the duration of hydrolysis – from 120 to 90 min. The developed method for producing microcrystalline cellulose makes it possible to reduce the cost of chemical treatment of the fibrous mass (acid concentration, treatment duration and hydrolysis temperature) by 1.5 times.

In this article, the technological aspects of obtaining a new effective composite material based on thermally modified wood filler and cement binders – thermal wood concrete – are considered. The influence of water content in thermally modified wood filler on the qualitative characteristics of a wood-cement composition has been studied. To solve the theoretical problems and applied issues of forecasting the technological parameters for the production of thermal wood-cement composition, the mathematical models of the effect of soaking duration and water temperature on the relative change in the mass (dampening) of the filler have been developed. At the initial stage, experimental studies have been carried out to determine the effect of pre-soaking the filler on the curing of thermal wood concrete and the quality of the resulting material. The samples have been produced via vibrocompression of a semi-dry mixture using dry and pre-soaked filler made of thermally modified wood, as well as via vibratory casting. The regularities of moisture transfer between the filler and the cement-sand mortar have been determined, and it has also been established that pre-soaking the thermally modified filler has a positive effect on the strength and quality characteristics of thermal wood concrete. On the contrary, the use of the dry filler made of thermally modified wood in this molding method has a significant negative impact on the quality of the finished material. The process of moisture absorption by the thermally modified wood filler by soaking has been studied separately. The main regularities and features of water sorption by the filler have been established at the time intervals of 30, 60, 120, 180 and 300 minutes and at the water temperatures of 3–4, 16–18 and 75–85 ℃. It has also been determined that additional water heating significantly accelerates the intensity of water sorption and the degree of dampening of thermally modified wood fillers, and the size of their particles does not play a significant role in the process. In this case, the recommended duration of soaking the thermally modified wood filler before preparing the mixture and molding the products made of thermal wood concrete via semi-dry vibrocompression is 30 minutes.

We have explored the effectiveness of using light-correcting covering materials for greenhouse structures when rooting the cuttings of various ornamental forms and varieties of the northern white-cedar (Thuja occidentalis L.). Two types of shelters have been tested: the modified spunbond at a density of 30 g/m2 with a photoluminescent phosphor integrated into its structure at a concentration of 0.8 % and the unmodified spunbond at the same density. Europeum-doped yttrium oxysulfide (Y2O2SEu) has been chosen as a photoluminescent phosphor. We have analyzed 11 varieties and forms of Thuja occidentalis L.: Rheingold, Mr. Bowling Ball, Woodwardii, Tiny Tim, Golden Smaragd, Mirjam, Golden Globe, Danica, Sunkist, Smaragd and Brabant. The response of the indicators of callusogenesis and rhizogenesis to the influence of a transformed light flux has been tested. A positive effect of the use of photoluminescent phosphors in rooting the stem cuttings of the northern white-cedar has been established. An increase in the indicators of regenerative ability and post-regenerative development of the root systems and the aboveground parts of the cuttings has been recorded, such as: the activity of callusogenesis, the number of adventitious roots formed, the length of the leading root, the total length of the root system, the height of the aboveground part and the diameter of the root collar. Callusogenesis has increased from 67.59 ± 2.05 % in the check to 76.81 ± 1.61 % when having integrated the photoluminescent phosphor. The number of adventitious roots formed has increased from 9.64 ± 0.43 to 11.44 ± 0.34 pcs., correspondingly. The total length of the root systems has increased from 64.56 ± 3.70 to 75.52 ± 2.77 cm, correspondingly. One-way analysis of variance confirmed the significance of the differences between the tested forms and varieties in each of the shelter options for most of the tested indicators. Two-way analysis of variance has revealed a significant effect of the positive impact of photoluminescent phosphors on callusogenesis, adventitious root formation, post-regenerative development of the root systems and the aboveground parts of the cuttings.

Published: April 2024

Remote photoplethysmography (rPPG) is a low-cost technique to measure physiological parameters such as heart rate by analyzing videos of a person. There has been growing attention to this technique due to the increased possibilities and demand for running psychological experiments on online platforms. Technological advancements in commercially available cameras and video processing algorithms have led to significant progress in this field. However, despite these advancements, past research indicates that suboptimal video recording conditions can severely compromise the accuracy of rPPG. In this study, we aimed to develop an open-source rPPG methodology and test its performance on videos collected via an online platform, without control of the hardware of the participants and the contextual variables, such as illumination, distance, and motion. Across two experiments, we compared the results of the rPPG extraction methodology to a validated dataset used for rPPG testing. Furthermore, we then collected 231 online video recordings and compared the results of the rPPG extraction to finger pulse oximeter data acquired with a validated mobile heart rate application. Results indicated that the rPPG algorithm was highly accurate, showing a significant degree of convergence with both datasets thus providing an improved tool for recording and analyzing heart rate in online experiments.

A Closer Look into the Correlates of Spiritual Well-Being in Women with Breast Cancer: The Mediating Role of Social Support
Authors: Novakov Ivana
Published: April 2024

The aim of this study was to gain insight into the relationship between spiritual well-being in breast cancer patients, psychological flexibility, social support, and personality traits. The research was conducted on 64 women (Mage=58.36, SD=11.30), while undergoing radiation therapy. Results showed that younger, less agreeable, and more conscientious patients were more likely to experience positive changes in life after the illness; greater perceived social support positively predicted sense of purpose/reason for being alive, and younger, more open to experience patients tended to be more hopeful. Full mediation effect of perceived social support was found – participants who were more agreeable and open to experience, through greater perceived support, achieved a higher sense of purpose/reason for being alive, while conscientious and psychologically inflexible individuals perceived less support, which resulted in diminished sense of purpose. Our results highlight the pivotal role of perceived social support, which could modulate and diminish negative psychological, spiritual and existential consequences of breast cancer.

Currency classification and Image to Text OCR are essential technologies that find applications in various domains, including finance, retail, and automation. The approach outlined in this paper has the potential to detect currencies from multiple countries. However, for practical implementation purposes, the focus is solely on Indian paper currencies. This system offers the advantage of convenient currency checking at any time and location, leveraging Convolutional Neural Networks (CNN) for effective implementation. Extensive testing was conducted on each denomination of Indian currency, resulting in an impressive 95% accuracy rate. To further refine accuracy, a classification model was developed, incorporating all pertinent factors discussed in the paper. Notably, the unique features of paper currency play a pivotal role in the recognition process. By emphasizing these elements and harnessing CNN technology, the proposed system demonstrates significant promise in accurately detecting and validating Indian paper currencies. It stands poised to serve various applications effectively. On the other hand, Image to Text OCR focuses on extracting text from images, enabling the conversion of non- editable documents into searchable and editable formats. Both technologies contribute to automation and efficiency in handling diverse visual information. Optical Character Recognition (OCR) is a technologydesigned to recognize and interpret both printed and handwritten characters by scanning text images. This process involves segmenting the text image into regions, isolating individual lines, and identifying each character along with its spacing. After isolating individual characters from the text image, the system conducts an analysis of their texture and topological attributes. This involves examining corner points, unique characteristics of various regions within the characters, and calculating the ratio of character area to convex area Prior to initiating recognition, the system creates templates that store the distinctive features of uppercase and lowercase letters, digits, and symbols. These templates serve as reference models for comparison during the recognition phase. During recognition, the system matches the extracted character's texture and topological Features with those stored in the templates to determine the exact character. This matching process involves comparing features of the extracted character with templates of all characters, measuring similarity, and ultimately recognizing the character accurately.

In the realm of forensic investigations, the management of evidentiary artifacts is a critical aspect that influences the integrity and admissibility of evidence in legal proceedings. The trustworthiness of evidence can be jeopardized by traditional evidence management systems’ frequent problems with data manipulation, unauthorized access, and lack of openness. Blockchain technology has surfaced as a viable approach to tackle these issues by offering a decentralized, transparent, and immutable foundation for data management in recent times. This paper explores the application of blockchain technology in forensic evidence management, highlighting its potential to enhance the security, integrity, and traceability of evidentiary artifacts throughout their lifecycle. By leveraging blockchain's inherent features such as cryptographic hashing, consensus mechanisms, and smart contracts, forensic practitioners can establish a tamper-proof chain of custody, ensure data integrity, and streamline the evidence management process. Moreover, blockchain- based evidence management systems offer benefits such as enhanced transparency, reduced reliance on centralized authorities, and improved collaboration among stakeholders. The paper discusses various use cases and implementations of blockchain technology in forensic evidence management, ranging from digital chain of custody records to decentralized forensic laboratories. Through a comprehensive analysis of the potential benefits and challenges, this paper aims to provide insights into the transformative impact of blockchain technology on forensic evidence management practices, paving the way for more secure, efficient, and trustworthy forensic investigations in the digital age.

It can be very befuddling for people to choose which music to tune in to from a wide run of alternatives accessible. Different proposal frameworks have been made for particular spaces like music, feasting, and shopping, catering to the user's inclinations. Our essential objective is to supply music recommendations that adjust with the user's taste. By analyzing facial expressions and client feelings, ready to pick up experiences into their current mental or enthusiastic state. Music and recordings offer a extraordinary opportunity to show clients with a huge number of choices based on their slants and past data. It is well known that humans make use of facial expressions to express more clearly what they want to say and the context in which they meant their words. More than 60 percent of the users believe that at a certain point of time the number of songs present in their songs library is so large that they are unable to figure out the song which they have to play. By developing a recommendation system, it could assist a user to make a decision regarding which music one should listen to helping the user to reduce his/her stress levels. The user would not have to waste any time in searching or to look up for songs and the best track matching the user’s mood is detected, and songs would be shown to the user according to his/her mood. The image of the user is captured with the help of a webcam. The user’s picture is taken and thenas per the mood/emotion of the user an appropriate song from the playlist of the user is shown matching the user’s requirement.
