Vladimir Solovyov – great Gnostic thinker
Authors:   Saint-Petersburg State University, Evlampiev I.I.
Published: October 2024

The article examines the well-known negative assessment of the philosophy of Vladimir Solovyov, associated with the fact that he developed the ideas of German philosophy of the 19th century, and did not follow the path of creating “Orthodox philosophy”. Within the framework of the assumption that since the middle of the 2nd century there were two interpretations of the teachings of Jesus Christ – Gnostic and Orthodox, it is proved that in the history of European philosophy from Origen to Schopenhauer, the tradition of mystical pantheism based on Gnostic Christianity absolutely prevailed. There was no “strictly Orthodox” philosophy in history, and, as shown by the attempt to build it, undertaken at the beginning of the twentieth century by S.N. Bulgakov, it is impossible due to the incompatibility of the dogmatic system of the church with meaningful philosophy. It is concluded that Solovyov’s main merit lies in the consistent development of the modern model of mystical pantheism, which was started by German philosophers of the 19th century (Schelling, Schopenhauer, etc.), taking into account the original interpretations of undistorted, Gnostic Christianity in Russian philosophy (Dostoevsky, Tolstoy).
Konstantin Leontiev: ascetism and aesthetics
Authors:   Institute of Russian Literature (Pushkinskij Dom) Russian Academy of Sciences, Fetisenko O.L.
Published: October 2024

The article briefly presents the main features and principles of K.N. Leontiev’s worldview and philosophizing. The main subject of the study is the relationship between the categories of “asceticism” and “aestheticism” in his philosophy, journalism and artistic creativity. The differences between Leontiev and the traditional idea of a conservative thinker are pointed out. The author pays attention to his “pedagogical” methodology, which manifested itself in communication with his closest students, and suggests that the universalism of the idea of “new eastern culture” developed by Leontiev is close to the philosophical program of Vl. S. Solovyov. Among other things, the article notes the idea that is usually missed in works about Leontief, that the discipline he preached was the discipline of a free spirit.
Symbolist Conceptualization of Myth: Vyach.I. Ivanov, A.F. Losev, L.A. Gogotishvili
Authors:   Sociological Institute of the Russian Academy of Sciences – Branch of the Federal Center of Theoretical and Applied Sociology of the Russian Academy of Sciences, Gravin A.A.
Published: October 2024

This article analyzes one of the concepts of myth by Vyacheslav Ivanov, Alexei Losev and Lyudmila Gogotishvili. The object of this research is Ivanov's studies related to the theory of myth (“Excursus: The Primary Myth in the novel “the Possesse”, “Dionysus and Pradionysianism”, “Dostoevsky: Tragedy – Myth – Mysticism”, etc.), “Dialectics of Myth” and “Supplement to the Dialectics of Myth” by Losev, as well as a series of contributions by Gogotishvili, where the concept of myth is used. In order to correlate the ideas of thinkers and reveal their conceptual continuity, we used historical-philosophical comparativism, methods of ideas history analysis, as well as the method of conceptual analysis of the use of the concept of myth. The main goal of this article is to investigate the mythological dimension of Gogotshvili's linguophilosophy in relation to its continuity with Ivanov's symbolism and Losev's dialectics, from an immanent and historical-contextual (from the point of view of continuity) perspective. It is shown that the linguistic dimension of myth (the myth language), according to Ivanov, implies a posteriori (in relation to mystical experience) character of its own formation. Myth language, according to Losev, implies it’s a priori givenness, epistemologically limited for a particular consciousness by sense bearing detachment. It is shown that the a posteriori givenness of myth, according to Ivanov, and the detachment of myth, according to Losev, ensure the “indirectness” of the meaning expression (or mystical reality) in language, which can be overcome by an intentional understanding of the meaning implied by language, i.e. by personal action. It is revealed that Gogotishvili believing the concept of myth as one of the basic categories of Russian symbolism. From the perspective of Gogotishvili's work, we consider the distinction between mythological and ordinary judgments, the relationship between myth and language in poetic and logical perspectives, as well as the nature of the application of the myth concept in the phenomenology of language and in the author's concept of binary and ternary symbols. It is shown that in Gogotishvili's linguophilosophy myth is “responsible” for mediating the expression of meaning in language and implies adequation between word and subject.
Between Imperial and Post-Imperial Discourse: Ideas of Empire and Revolution in the Optics of XXI Century Researchers (Res. in: The idea of empire and the idea of revolution in Russian philosophy and culture of the XIX–XX centuries: a collective monograph / Edited by I.I.

The paper analyses the collective monograph: “The Idea of Empire and the Idea of Revolution in Russian Philosophy and Culture of the XIX–XX Centuries”, its content being a reflection on one of the most intellectually acute and complex contradictions of Russian history – the problem of empire and revolution. This problem invariably awakens philosophical thought, forcing it to search for an explanation of the notorious “pendulum of Russian history”, the genesis of power, the vector and track of Russian history, which are intellectual outgrowths of the fundamental problem – the problem of Russian civilizational and state identity. The content of the work is an analysis of empire and revolution – the main concepts that are in the focus of philosophical interest and reflection in Russian culture of the XIX–XX centuries. Its aim is to demonstrate the theoretical demand to continue the analysis and philosophical reflection of the concepts of empire and revolution, with the task of rethinking and reinterpreting them. The thesis is presented about the inexhaustibly traditional historical-philosophical narrative (liberalism-conservatism) and the discursively traditional nature of the range of topics, problems and questions, centred on the concepts of “empire” and “revolution”, with the same inexhaustibly traditional duality of interpretation (“us–them”, “East–West”). The result of the analysis of the sections that make up the content of the monograph is the conclusion about the epistemological and axiological value of the concepts of empire and revolution, and the heuristic productivity of the works related to their analysis in the context of the challenges faced by the Russian society and state. The latter can be used as analytical tools for works that develop and deepen the problems of empire and revolution on a modern historiographical basis. The historiographical basis of the article is the works of well-known Russian and foreign authors specializing in this field of humanities, and the methodological basis is hermeneutic analysis with the involvement of the discourse of cultural studies, political science and history.

A new method to uptake vitamin B12 in aqueous solution as pharmaceutical preparations by adsorption on the solid phase surface by using a multi-layer graphene oxide derivative compounds while the ultrasonic frequency wave was used to increase the efficiency of the extraction of drug from aqueous solution. Interlayer drug extraction conditions were optimized by studying a number of conditions that affect the extraction rate, including pH, ultrasound frequency, residence time of the solution inside the ultrasound device, the effect of the amount of graphene oxide derivative, and vitamin B12 concentration. The effect of temperature was also studied and a number of thermodynamic factors were generated. From the results, it was found that the best weight for the economically useful graphene oxide derivative is 0.01 grams at a concentration of 20 ppm relative to the concentration of the vitamin using an acidic medium of 2.1. The best temperature is 40 0C and within 50 Hz of the frequencies of the ultrasound device during the incubation period of 50 minutes. The proposed method was also applied to pharmaceutical samples containing vitamin B12, and the extraction rate was 95.35 %, with a very small error rate of 0.0465.

Berry crops play a significant role in Azerbaijan’s agricultural sector. Pre-processing berry pulp with enzyme preparations can enlarge the quantity of some useful organic molecules in their extracts, such as vitamins, anthocyanins, polyphenols, and monosaccharides. These compounds are highly valuable for the food industry, and enhancing their concentration is a relevant issue. The current investigation aimed to study the effect of the enzymatic maceration process on the pulp of grapes, cherries, and strawberries on the content of the aforementioned substances in their extracts. The berries were treated with pectinase and cellulase preparations. The bioactive components in homogenate were determined and separated using high-performance liquid chromatography, with ultraviolet and mass spectrometric detection. A slight increase in the concentration of ascorbic acid was observed in the obtained extracts. Several anthocyanins and polyphenols were successfully identified in the investigated berries. Enzymatic treatment caused a sufficient increase in their overall concentration, as well as the content of some individual components. Coumarins were an exception, as their concentration decreased due to enzymatic treatment. It was demonstrated that the use of pectinase and cellulase preparations increased not only the glucose but also other monosaccharides’ content. The combination of two enzyme preparations had the greatest positive effect on the monosaccharide content in the investigated extracts. The obtained data are of great importance for the food industry regarding the studied berries and indicate the potential of enzymatic maceration as a method for increasing the content of bioactive components in grape, cherry, and strawberry products.

Application based technology solution is nowadays preferred to achieve the performance of the cooling system configuration at its best. Therefore, benchmarking is an essential criterion which would add value to the optimum system design for various applications. In this study, a case study is carried out for a Milk Bar (small supermarket) to evaluate the potential of R744 cooling system for the similar cooling demand and tropical conditions. Field data collected during a particular time and temperature zone is further used to develop a yearly round performance of the HFC plug-in cabinets for MT and LT applications. The data is further used to develop a centralized R744 booster system that would meet the similar cooling load and demand of all the cabinets in the shop. Based on the cooling loads for the HFC unit, the yearly performance of the R774 booster system is calculated and compared to the existing plug-in solution. It is observed that the yearly electric energy consumption for the R744 centralized refrigeration system is 3.3 M W·h, 24% lower than with the existing solution based on HFCs. Moreover, the economic prospective of the R744 is further discussed to alternative material for the components and centralized unit structure which could empower the system with more reliability and an effective substitute to the synthetic technology for smaller supermarkets.

The actual problem of electrodynamic modeling of a four-channel antenna with an octave operating frequency range has been considered. The results of numerical electrodynamic modeling of a four-channel antenna have been presented. The considered antenna with an octave operating frequency range is a rectangular curtain comprising four independent non-equidistant channels. Numerical electrodynamic modeling of a four-channel antenna has been carried out in the ANSYS HFSS software package, with the convergence parameter DeltaS = 0.01. As a result of the simulation, the frequency characteristics of each channel have been obtained: VSWR, gain, reflection coefficient, directional pattern. The antenna provides a scanning angle as part of an ultra-wideband digital antenna array of at least ±30° in azimuth and from 0° to 60° in elevation. The gain of the antenna channels in the operating frequency range is not lower than 6 dB. According to the simulation results, the VSWR of each channel of the antenna in the operating frequency range does not exceed 2.55. To minimize the influence of mutual coupling of channels on the antenna characteristics, the distance from the phase centers of the curtain emitters to other elements of the ultra-wideband digital antenna array should be at least a wavelength in free space at the lower frequency of the operating frequency range. It has been shown that the considered four-channel antenna provides an octave operating frequency band and can be used as part of an ultra-wideband digital antenna array for direction finding of radiation sources.

Published: October 2024

The continuous and dynamic development of satellite communication systems actualizes the issues of the efficiency of using the frequency and channel resource of communication channels. In the conditions of using packet types of transmissions, fragmentation of user data packets is one of the ways to increase the efficiency of using a channel resource. A wide variety of approaches to the formation of the channel layer and their functional ambiguity in the conditions of fragmentation increase the level of uncertainty in the choice of the protocol stack used to build a communication channel, which in turn creates a prerequisite for a decrease in the quality of the use of the channel resource. In view of this, the task of modeling the procedure for forming frames of fragmented user data packets is relevant, taking into account possible variants of non-standardized protocol block headers at the channel level. Based on the studied non-standardized headers of channel-level protocol blocks, reflecting the features of their formation, to present a model for the formation of frames of fragmented user data packets. This will make it possible to identify the necessary set of informative features, the study of which will make it possible to efficiently and with high probability recognize frames of fragmented packets in a digital data stream with packet switching in channels of satellite communication networks for various purposes. The article considers the procedure for forming frames of fragmented user data packets with non-standardized headers of protocol blocks at the channel level used in data transmission channels with packet switching of satellite communication systems for various purposes. The structural and structural-linguistic models of frames of a fragmented package of user data in conditions of transmission over a satellite communication channel have been developed. The structure of signals with fragmented packets of user data based on a directed graph is presented and investigated. The service level indicators of the fragmented user data package frame formation model were evaluated according to parameters that allow an objective assessment of the effectiveness and validity of the use of fragmentation in data transmission in satellite communication channels. The data obtained using the developed model allows us to qualitatively assess the indicators of the level of service of the data transmission channel with fragmentation of user message packets and reasonably prove the effectiveness of the fragmentation described by the model when it is necessary to split the desired message into parts when it is transmitted over the CCC channel.

Published: October 2024

The article is devoted to the application of deep neural networks for predicting time series that characterize target trajectories in over-the-horizon radar images (OTH). Such neural networks are effective in cases where traditional methods precision is not sufficient. Method, described in this work relies on the similarities of an area close to the target in the next radar image to the corresponding areas in the previous images along the same trajectory. This approach in similar to “optical flow” calculation, which is used for tracking object motion across an image sequence. However, existing neural network architectures, such as FlowNet, SpyNet and PWC-Net are based on the “dense” optical flow and thus require definition of sample flow vectors for the entire images. Sample radar images, available for model learning, usually have flow vectors available only for a set of points in the images. Besides, OTH radar images are typically represented in azimuth, range and speed dimensions, which makes it difficult to apply existing architectures designed for optical images. OpenCV, a popular framework for image processing contains an implementation of “sparse” optical flow based on the Lucas-Kanade method and allows to track the motion of isolated areas in the image. However, this method is primarily designed for optical images and does not support adaptation to the specifics of radar images. The article provides an example of choosing the type and characteristics of a neural network for the task of trajectory extrapolation. A comparative assessment of various variants of neural network architectures is provided. The possibility of solving the problem using a combination of convolutional and recurrent neural networks is shown. A significant advantage of the proposed trajectory processing approach has been demonstrated. That is the ability of an adaptive system to effectively determine the most likely options for continuing the target trajectory by learning from data.

The problems of analytical and computer research of dynamic models of repair and operation of technical vehicles used in railway transport are among the urgent problems related to ensuring safety and stability of traffic, with the development of digital twins and the improvement of monitoring and diagnostic systems. The analysis of models described by various types of multidimensional nonlinear differential equations requires the use of modern methods of dynamical systems theory, numerical optimization and computer algebra. The purpose of the article is to conduct a qualitative and numerical analysis of mathematical models of organizational and technological processes (OTP) in railway transport, as well as the synthesis of new controlled OTP models. Nonstationary generalizations of a two-dimensional dynamic model describing the repair process of railway transport equipment are proposed. Various cases of using constant and time-dependent parameters are considered. The case of linear and exponential dependences of parameters on time is studied. For the studied models, trajectories are obtained taking into account the variation of constant parameters and taking into account the choice of parametric dependencies, a comparative analysis of the results is presented. The formulation of the problem of optimal control of the number of repaired and repaired railway wagons is proposed. Promising methods for solving this problem using numerical optimization methods, including those inspired by nature, are described. The results can be used in the tasks of constructing and analyzing mathematical models of dynamic systems, in the tasks of numerical modeling of transport systems and technological processes, in the tasks of optimizing the number of vehicles and improving the transportation process, as well as in the tasks of creating digital counterparts in the transport industry.

Published: October 2024

The article considers the solution of the traveling salesman problem using reinforcement learning. This task is to find the optimal route that passes through the specified cities at least once and then returns to the original city. The traveling salesman problem belongs to the class of NP-hard problems, and therefore finding an exact solution for sufficiently large data sets using classical mathematical methods turns out to be impossible in a reasonable time. The aim of the work is to increase the efficiency and speed of solving the traveling salesman problem with a large number of vertices by using the reinforcement learning method. A variant of solving the traveling salesman problem using the Q-learning algorithm is considered, which allows the agent to learn the optimal behavior strategy in the process of interacting with the environment, which is a set of cities and roads between them, which are modeled as a graph. Within the framework of this study, a software package was developed to solve the traveling salesman problem using reinforcement learning. A series of experiments related to the appearance of unforeseen conditions complicating the work of a traveling salesman, such as the appearance of "problem" zones or zones, the passage through which gives a reduction in time. The results of the experiments showed the capabilities of the developed algorithm for adaptation to changes and obstacles of the environment. The resulting algorithm shows itself to be more stable and reliable compared to the algorithms obtained by classical solution methods. The solution of this problem can be used in practice in a variety of real situations, including optimization of deliveries or network routing, assistance in the work of logistics departments of various transport, postal and courier services.

Authors: Bablad Anita
Published: October 2024

Background: A high-risk pregnancy (HRP) is defined as one complicated by factors that negatively impact maternal and/or perinatal outcomes. These pregnancies have an increased likelihood of morbidity and mortality for both the mother and the fetus. Such cases require intensive antenatal care, sophisticated maternal and fetal monitoring, and often complex management decisions to optimize outcomes. Therefore, this study was conducted to evaluate maternal and perinatal outcomes in high-risk pregnancies. Objectives of the study were to evaluate maternal and perinatal outcomes in high-risk pregnancies, identify key factors contributing to these high-risk conditions.
Methods: This prospective study was conducted from July 2023-June 2024. The study included 94 pregnant women with high risk factors with gestational age more than 28 weeks attending OPD, IPD and labor room.
Results: The study included 94 pregnant women with high risk factors with gestational age ≥28 weeks. Majority of the participants were aged 20-24 years (42/44.68%). Most participants were Hindu (77/81.91%) and from lower socioeconomic classes (44/46.81%). Postpartum haemorrhage (PPH) was observed in (30/31.91%) of cases was the most common immediate complication. Surgical site infection (24/25.52%) was being other common maternal morbidities. The most common cause of perinatal morbidity was respiratory distress syndrome (13/13.83%). The perinatal mortality rate was (25/26.59%). Previous caesarean section (CS), anemia, Rh negative pregnancy was the common risk factors associated with more adverse pregnancy outcomes. Previous CS and multiple pregnancy were most commonly associated risk factors with increased risk of PPH. With vigilant and careful detection of high-risk pregnancies and timely intervention, there was no maternal mortality in our study.
Conclusions: In our study we emphasise on the importance of awareness of first trimester registration, early identification of risk factors, frequent hospital visits for regular antenatal check-up, and providing quality antenatal care.

Authors: Dolma Kelsang , M. Gayathri
Published: October 2024

Background: Adolescence is a vital transition phase in human life, with menstruation being one of the most distinctive features. In India, menstruation in females can lead to the introduction of new vulnerabilities due to socio-cultural barriers. The sociocultural barriers often label periods as impure and have added stigma leading to ignorance of hygienic health practices.
Methods: A pre-experimental research study was conducted among 60 adolescent girls who were divided into a researcher group and a buddy group studying in Adarsh Vidya Dhama, Bengaluru. The researcher group (30 older adolescent girls) was given planned teaching by the student researcher. Based on the post-test scores, five buddies were trained by the student researcher to disseminate information to the buddy group. Confidentiality was maintained throughout the study.
Results: The findings of the study depict that, in the researcher group the mean post-test knowledge score is 16.23 which is higher than the mean pre-test scores of 11.87. The obtained ‘t’ value is -11.25 and the calculated p=0.000 (at p<0.05). Similarly, the mean post-test knowledge score after the buddy approach is 16.33 which is higher than the mean pre-test score before the buddy approach which is 11.40. The obtained ‘t’ value is -10.850 and the calculated p=0.000 (at p<0.05).
Conclusions: Imparting knowledge of menstruation and menstrual hygiene using the buddy approach is cost-effective and impactful way to convey information. It promotes open communication often reaching more effectively than the professional health team.

Authors: Krati KM , Martolia Jaya , Painuly Neelam , Singh Amandeep
Published: October 2024

Microbes, also referred to as microscopic creatures because of their minuscule size and invisibility to human sight, are single-celled microorganisms. The first microorganism was discovered between 1665 and 1683 by Robert Hooke and Antoni van Leuwenhoek. There are two categories of techniques for examining microbial activity. methods used in vitro and in vivo. Experiments and tests carried out in a laboratory setting, typically without the presence of a living organism, are referred to as in vitro methods. By creating microbial cultures, cell lines, cell cultures, etc., we may do in vitro experiments. Scientists can study biological processes, assess the effects of medications, and understand systems without having to deal with the complexities of a whole organism by employing in vitro techniques. Growing cells outside of the body in a controlled setting for a range of studies is known as cell culture. Tissues are grown and kept in a lab setting for tissue culture. It is essential to research creating anti-infection therapies. To evaluate a substance's antibacterial activity, in vitro methods such as the brothdilution method and discdiffusion method are commonly used. There are different methods available for the testing of antimicrobial activity and the methods are the agar disk diffusion method, Agar well diffusion method, cross streak method, Bioautography, dilution method, Time kill test, ATP bioluminescence etc. Techniques for determining novel antimicrobial agents and testing for antibiotic susceptibility have been employed. Compared to in-vivo procedures, in vitro methods are less costly. To guarantee an accurate experimental approach, these techniques may be the answer.

Oxaliplatin triggered hypersensitivity reactions in colorectal cancer patients: Case report
Authors: Raj Aran Khadga , Banga Ayushreeya
Published: October 2024

Colorectal cancer stands as a significant global health concern, encompassing adenocarcinoma of both the colon and rectum. Recognized risk factors include advancing age and medical history of inflammatory bowel conditions like Crohn's disease or ulcerative colitis. Oxaliplatin, a platinum-based chemotherapy agent, serves as the frontline treatment for colorectal cancer due to its cytotoxic effects on cancerous cells. However, its use is not without complications, as hypersensitivity reactions can occur, posing challenges in patient management. This case report discusses two instances where patients undergoing chemotherapy for colorectal cancer developed grade two hypersensitivity reactions following oxaliplatin administration, the Naranjo probability scale was used to analyze the causation of the adverse drug reactions (ADRs), and a score of 6 was obtained, indicating oxaliplatin as a probable cause of the hypersensitivity reactions. In both cases, treatment was promptly halted upon manifestation of symptoms, and patients were administered intravenous steroids along with anti-histamines. This intervention resulted in significant improvement in the patients' conditions. Both genders are equally susceptible to such reactions, emphasizing the need for gender-neutral awareness and precautionary measures among medical practitioners. This case report serves as a reminder of the potential adverse effects associated with oxaliplatin therapy in colorectal cancer patients. Heightened awareness among healthcare professionals regarding the risk of hypersensitivity reactions is imperative to ensure timely detection and appropriate management, thereby optimizing patient outcomes. Consequently, while giving oxaliplatin to cancer patients, healthcare professionals need to use extreme caution.

(Za)angażowanie młodzieży. Ku pedagogice i edukacji zaangażowanej społecznie
Authors: Mikut Małgorzata
Published: October 2024

Współczesność, w której dorasta młode pokolenie, jest pełna paradoksów i wyzwań, a dynamicznie dokonujące się zmiany rysują niedaleką przyszłość jako niekoniecznie optymistyczną. Dorastający doświadczają nowych sytuacji często jako pierwsi wraz ze wszystkimi żyjącymi generacjami, a zatem nie mogą skorzystać z doświadczeń i wiedzy starszych. Co zatem pozostaje młodym, by nie utracili kontroli nad swoim życiem?
Nadzieję niosą nauczyciele i pedagodzy zaangażowani w realizację przemyślanych programów uczenia się i projektów społecznych rozwijających sprawstwo. Istnieje wiele bardzo dobrych praktyk, ponieważ zaangażowani społecznicy chętnie dzielą się wiedzą i doświadczeniem. Dla wielu młodych szkoła to jedyne miejsce spotkań z rówieśnikami i nawiązywania bliskich relacji. Warto wiedzieć, kim są uczniowie, w jakich środowiskach żyją na co dzień. Bardzo ważne jest, by mogli od wczesnego okresu swojej edukacji uczestniczyć w aktywnym procesie uczenia się i mogli odkrywać i rozwijać swoje naturalne uzdolnienia. Szkoła i każda inna przestrzeń edukacyjna ma ogromny potencjał tworzenia wspólnoty. Istotne jest też to, jak nauczyciele i pedagodzy postrzegają złożone problemy społeczne i siebie jako inicjatorów zmian. Czy potrafią działać zespołowo i podejmować wspólne działania z młodzieżą?
Pedagogika i edukacja zaangażowana społecznie stwarza szanse na rozwój wielu umiejętności społecznych młodzieży niezbędnych dla inicjowania przez nią zmian i mierzenia się z problemami przyszłości. Głównym celem tej monografii jest przedstawienie relacji/powiązań między przemyślaną praktyką edukacyjną a rozwojem (za)angażowania społecznego młodzieży. Zaangażowanie społeczne jest uwarunkowane wieloczynnikowo i może objawiać się w różnych formach. Jest powiązane z zaufaniem i uzależnione od doświadczeń społecznych. Podwaliny zaangażowania społecznego młodzieży tworzone są już we wczesnym okresie ich życia w znaczących środowiskach wychowawczych.
Ważne jest, by młodzi mieli okazje do poznawania siebie i rozwijania własnych potencjałów dzięki uczeniu się działania w środowiskach edukacyjnych z kulturą zaufania, otwartą na zaangażowaną współpracę z innymi i promującą aktywizm społeczny. Edukacja zaangażowana społecznie nie może być realizowana w oderwaniu od życia społecznego. Szkoła jest położona w określonym środowisku z całym dobrodziejstwem problemów, wyzwań i zasobów społecznych. Młodzież ma w sobie potencjał wprowadzania konstruktywnych zmian, pod warunkiem że będzie miała prawo decydowania w sprawach jej dotyczących i okazje do rozwijania i trenowania umiejętności społecznych. Czym jest zaangażowanie społeczne? Jak angażować młodych? Skąd czerpać pomysły na działania z młodymi? Czy dorośli mogą uczyć się od młodych? Na te i inne pytania dostarczają rozdziały tej monografii.
Evaluation of Residual Stress in Stir-squeeze Cast Aluminium – Fly Ash Composites Using X-Ray Diffraction Method
Authors: Bharathi V. , Anilchandra A. R.
Published: October 2024

Determination of residual stresses in metals, subjected to secondary processing, is necessary from the point of view of their applications and is widely studied in literature. However, residual stresses induced during service is generally ignored when evaluating the performance of the component. The residual stress in a component could be tensile or compressive in nature and eventually affects its service life under external loading. In this regard, industries demand rapid, efficient, and easier methods of non-destructive testing to identify and control the residual stress in such components. The present work aims at evaluation of residual stress in an LM-25 aluminium alloy/fly Ash Metal Matrix Composites (AMC) after subjecting the specimen to dry sliding wear tests. X-ray diffraction technique was used to measure the residual stress in the “pin” specimen of the pin-on-disc set-up. The residual stress was ~ 24 % higher in the composite compared to the un-reinforced alloy after the wear test while the wear rate, measured in terms of weight loss of the pin, was lower by about 50%, under similar test conditions.

Analysis of Heat Exchanger for Single-Phase Cooling Applications using Micro-channels of Copper Material
Authors: Barhatte Surendra , Lele Mandar
Published: October 2024

The design of a microchannel heat exchanger can be achieved using various approaches. The design includes various materials, such as ceramics, silicon, metals, and polymers, that are used to make microchannels, depending on their specific requirements. Polymers such as silicon, glass, and other polymeric materials are utilized on metallic substrates. The current study includes microchannels fabricated from metallic copper. Further, the design solutions do not consider the implications of the second law of thermodynamics. Hence, performing an energetic analysis of microchannels is imperative to design and assess thermodynamic systems that use them efficiently. One technique to improve a thermodynamic system's efficiency is using a well-designed microchannel heat exchanger with excellent energetic performance. This can be achieved by creating a thermodynamic system that eliminates energetic losses and limits only unavoidable losses. The use of high-conductivity material like copper also achieves this. To identify possible reasons for exergy loss and perhaps address them, a thorough energetic analysis of an existing heat exchanger is necessary. A microchannel heat exchanger with 19 microchannels in a flat tube is considered for this study. The study finds the energetic losses, which are useful for the thermal design of the heat exchanger.
