En-Fleshed Practicing in Organisations Flesh as Elemental Carnality and Formative Medium for Organising Sustainability Development
Authors: Keupers Wendlin
Published: November 2023

Based on Merleau-Pontys’s philosophy of flesh, this paper outlines possibilities for organisational practices towards sustainability development. In order to elucidate these en-fleshed practices, the paper begins by presenting Merleau-Ponty’s phenomenology of the body and perception as well as his ontology of ‘flesh’. In particular, flesh is interpreted as elemental ‘carnality’ and formative medium. As such, it is processed through sensual and reflexive doubling as a reversibility and chiasm of the sentient and the sensible. This understanding opens for the path to a post-dualistic, transformative approach towards processes of post-dualistic ‘wild being and ‘inter-be(com)ing’ in organisations. These concepts of Flesh are related to affect and imagination as well as organization and sustainability. The paper then offers some practical and political as well as research implications and concludes with some final perspectives on possible enfleshed inter-practices of sustainability.
Convicting the Innocent: An Analysis of the Effects of Wrongful Convictions and Available Remedies in Canada
Authors: Pacholski Casandra , Anderson Gail
Published: November 2023

The past three decades have seen at least 3,200 exonerations across North America. While this number continues to grow, attention must be turned to facilitating successful re-entry amongst this group. By conducting a content analysis of 57 Canadian exonerees, I gathered demographics and common case characteristics to assess the re-entry success of exonerees. Successful re-entry was incredibly difficult for the majority of exonerees due to a lack of specialized re-entry services, counselling, compensation legislation, and healthcare. Exonerees are suffering in the same ways as legitimate offenders while incarcerated and afterward, all while being offered drastically less assistance from Canada’s institutions and government
Imputation Missing Value to Overcome Sparsity Problems in The Recommendation System
Authors: Sri Lestari  , M. Elrico Afdila  , Yan Aditiya Pratama
Published: November 2023

A recommendation system is a system that provides suggestions or recommendations to a product or service for its users. One of the problems encountered in the recommendation system is sparsity, namely the lack of available data for analysis, resulting in poor performance of the recommendation system because it cannot provide the proper recommendations. On this basis, this study proposes the mean method and the stochastic hot-deck method to calculate missing values to improve the quality of the recommendations. The experimental results show that the hot-deck imputation method gives better results than the mean imputation method with smaller RMSE and MAE values, namely 2,706 and 2,691.
Muhammed Ferid Vecdi's View About Miracles
Authors: Tanrıkulu Sadık
Published: November 2023

Muhammed Ferid Vecdi (1878-1954), kelam ilmi açısından yeni arayışlar dönemi olarak nitelenebilecek bir dönemde, anılan arayış faaliyetlerinin yoğun yaşandığı Mısır’da yaşamıştır. Kendisi, benzeri pek çok Arap âliminde görülen nakilci
yaklaşımı benimsememiş, İslami konularla ilgili olarak doğrudan ve çok yönlü olarak fikir imalinde bulunmuş mütefekkir bir şahsiyettir. İtikadi meselelerle ilgili olarak mevrusu/geleneği değerlendirmekle birlikte eleştiriye de
tabi tutmuştur. Ona göre genelde imani meseleler, özelde de nübüvvet ve ona müteallik vahiy ve mucize gibi konularda bu gün yeni sorular ve şüpheler ortaya çıkmış bulunmaktadır. İmani meselelerde ortaya çıkan yeni soru ve şüphelerin
kaynağı da elbette Batının materyalist ve pozitivist felsefeleridir. Batıdan gelen itikadi şüpheler özellikle gençlerin zihin dünyalarında iz bırakmaktadır. Bu sorulara geçmiş ulemanın verdikleri cevaplar -Ferid Vecdi’ye göre-
artık yetersiz kalmakta, gençlerin zihinlerindeki şüpheleri izale edememektedir. Dolayısıyla bu gün Batının modern biliminden, özellikle deneysel tecrübelerinden de istifade edilerek kelami meseleler etrafında ortaya çıkan soru
ve şüphelere mukni cevaplar aranmalıdır. Yoksa gençler çevre etkisiyle dışa vuramadıkları inanç sorunlarını iç dünyalarında bastıracaklardır. Fakat bir süre sonra bu sorunlar zihinlerde sığışmayacak ve bir gün kendilerini mutlaka
dışarıya vuracaklardır. Bu makalede müellifin özellikle mucizeler etrafında ileri sürdüğü fikirler ele alınacaktır. Bu konunun ele alınması bir kelam âliminin tecdit arayışını tebellür ettirmeye matuf olarak kelam ilmine ilmi bir
katkı ortaya koymakla birlikte aynı zamanda başta Şeyhülislam Mustafa Sabri Efendi olmak üzere pek çok yazar tarafından Muhammed Ferid Vecdi’ye yöneltilen ‘mucizeleri inkâr ediyor olma’ ithamının da hakikatini ortaya koymuş olacaktır
ki mesele iddia sahiplerinin vurguladıkları gibi değildir.

Bu çalışmanın amacı, okul yöneticilerinin yönetici seçme ve görevlendirme yönetmeliğilyle ilgili görüş ve önerilerini almaktır. Nitel araştırma yöntemlerinden olgu bilimi deseni tercih edilmiş olup bu yöntemin tercih edilmesinde konuyu
derinlemesine inceleme fırsatı sunması etkili olmuştur. Samsun ilinin merkez ilçelerinde görev yapan okul yöneticilerinden 26 tanesi seçkisiz örnekleme yöntemi ile seçilmiştir. Çalışmaya katılan oklu yöneticilerine uzman görüşü
alınarak hazırlanan yarı yapılandırılmış görüşme formları uygulanmış olup, katılımcıların isteğiyle kişisel bilgiler ve çalışılan kurum bilgileri paylaşılmamıştır. Araştırmamızın sonucunda katılımcı yöneticilerin, yöneticilerin
sınavla seçme ve mülakatla seçmeye eleştiriler getirdikleri görülmüştür. Özellikle mülakatla yönetici seçmeye liyakat ve güven sorunları nedeniyle büyük oranda olumsuz baktıkları anlaşılmıştır. Sınavla yönetici seçilmesine ise
yönetici vasfı olmayanların sınavı kazanabilmesi nedeniyle eleştiri getirdikleri görülmüştür. Bunun yanında ek-1 ve ek-2 ile yöneticilikte veya öğretmenlikte yapılan çalışmaların yönetici olurken değerlendirilmesinin doğru olduğu
ancak içerik olarak bu belgelerin tekrar değerlendirilmesi gerektiği de araştırma sonuçlarında ortaya çıkmıştır. İdeal yönetici seçme ve görevlendirmenin nasıl olması gerektiği sorulduğunda ise yöneticilerin büyük çoğunluğunin
mevcut yönetici görevlendirme yönetmeliğinin eksik yönlerinin değiştirilmesi veya yöneticilerin ayrı seminerler sonucunda hazırlanan nesnel sınavlarla atanması gerektiği fikirleri ağırlık kazanmıştır. Çalışmaya katılan yöneticilerin
büyük bir kısmı yöneticiliğin, öğretmenliğe ek bir görev olmaktan çıkarılmasını ve görevlendirme yerine atama şeklinde yönetici atamanın yapılması gerektiğini önermişlerdir.

Biologic Medications for the Treatment of Psoriasis - Main Groups and Dosing System
Authors: Bedeer Sabry Elsherbiny
Published: November 2023

This review explores the evolving landscape of psoriasis treatment with a focus on the transformative impact of biologic drugs. Psoriasis, a prevalent and persistent skin condition characterized by red and scaly patches, historically relied on topical, phototherapeutic, and systemic treatments, each with limitations. The advent of biologics represents a significant advancement, offering targeted interventions by addressing specific immunologic mechanisms underlying the disease. Biologics are now considered the preferred systemic therapy for chronic moderate-to-severe plaque psoriasis, particularly when conventional treatments prove ineffective or present disadvantages. The review delineates the mechanisms of action for biologics targeting tumour necrosis factor-alpha (TNF-α), interleukin-17 (IL-17) and interleukin-23 (IL-23). Specific drugs under each category, including etanercept, infliximab, adalimumab, secukinumab, ustekinumab, and others, are detailed with recommended dosages. Biologics have demonstrated substantial effectiveness, with clinical trials and real-world studies showcasing significant improvements in disease severity and patient’s quality of life. Notably, these drugs exhibit rapid action, often yielding noticeable changes within weeks. While biologics have revolutionized psoriasis treatment, the review emphasizes the importance of judicious use due to potential side effects such as injection-site reactions and respiratory infections. Serious adverse events, including infections and autoimmune reactions, necessitate careful patient selection and monitoring for safety. In conclusion, biologics offer a precise and effective approach to psoriasis treatment, promising marked symptom improvement and enhanced quality of life. The review underscores the need for responsible utilization, considering patient-specific factors, and anticipates ongoing advancements in biologics for improved control over this chronic dermatitis.

Cuando me senté a escribir estas líneas, una vez concluida la lectura del libro de Víctor Raúl Martínez Vázquez, me di cuenta de lo difícil que resultaba hacerlo que todas las implicaciones del texto. Me saltaba sobre todo por la presente situación de Oaxaca (agosto-septiembre de 2006) y me preguntaba qué tan lejos teníamos que dejar ésta de la reflexión más me preguntaba qué tan lejos teníamos que dejar ésta de la reflexión más académica que pudiera hacerse sobre el libro. Es cierto: el autor se propone objetivos bien precisos que quedan delimitados en el título mismo: esto es, nos relata la historia de las dos instituciones de instrucción superior públicas más importantes que ha tenido el estado de Oaxaca en los siglos XIX y XX: en primer lugar el Instituto de Ciencias y Artes del estado, de larga vida, y en segundo, la de la universidad, creada apenas a mediados del siglo pasado del seno del instituto mismo, ambas unidas no solamente por la historia institucional de continuidad que tienen, sino, sobre todo, porque se trata de vincularlas con otra historia, la del prócer Benito Juárez. De esta manera, el libro viene a se otro aporte a los festejos conmemorativos del bicentenario del nacimiento del Benemérito de las Américas que se celebra este año y, a la vez, reflexión sobre lo que ha sido la instrucción superior pública del estado a lo largo de dos siglos, que no es poco decir y que da cuenta del mérito principal de esta obra. En este sentido, puede decirse que se trata de un aporte significativo del autor a la historiografía que sobre las instituciones de educación superior ha venido realizándose últimamente en México, sobre todo en términos de datos y también de sensibilidad frente a la propia historia. El libro está basado en una investigación exhaustiva, pero también en la vivencia personal que el autor ha tenido con su universidad. Los temas a los que se refiere Víctor Raúl Martínez son innumerables, principalmente relacionados con el marco normativo, la estructura orgánica, su gobierno interior, las relaciones que se establecen con los gobiernos locales, las cátedras, los planes de estudio, las formas de organización de los profesores y de los estudiantes, la evolución de la matrícula, los directivos, los catedráticos, los alumnos sobresalientes, el financiamiento, el patrimonio, la sindicalización, la autonomía y el cambio de instituto a universidad, entre otros más.

Anchored fish aggregating devices (AFADs) have been widely used for fishing in Thai waters. However, abandoned, lost, and discarded fishing gears (ALDFGs), including lost AFADs, may cause environmental impacts. Fishing gear marking (FGM) is considered as a tool to help identification of ALDFGs. The main objective of this study is to compare the durability represented by the percentage of remaining condition (R-value) of three material types of FGM applied for AFADs, i.e., stainless steel (SS), colored acrylic (CA), and polypropylene (PP). This study was carried out using 50 AFADs deployed in the Gulf of Thailand (GOT) and the Andaman Sea (ANS) between July and October 2020 in cooperation with 10 fishers. The AFADs were deployed in similar habitat (bottom depth and type) between the GOT and the ANS. The three material types of FGM were assumed to be sufficiently durable to last for the lifespan of the AFADs in both the GOT and the ANS (within 2 months and 3.5 months, respectively) though some FGMs in the ANS were detached from cable ties or broken before AFADs were lost. The loss of AFADs and FGMs was mainly caused by adverse weather condition (rough sea). Only data from the ANS was included in comparative analysis due to the insufficient variance data obtained from the GOT. The analysis revealed that SS had the higher durability than CA and PP when the AFADs lasted for less than 3.5 months. As a result of our study, some recommendations were made. For example, the cable ties can be replaced by ropes or threads to improve the installation method. This study serves as a basis to develop FGM and to support responsible fisheries. Beneficiaries of the study include fisheries policy makers, managers, and fishers.

The institution of supervisory judges and observers is a new institution that was born with the enactment of Law No. 8 of 1981 concerning the Criminal Procedure Code. The task of supervision and observation is very important, considering that its duties are not only related to convicts who have been sentenced, but also to convicts who have finished serving their sentences with the aim that there is a guarantee that the decisions handed down by the court are carried out properly. Purposes of the Research: The type of research used is normative legal research using a statute approach, a conceptual approach, and a case approach. While the sources of legal materials used are primary legal materials, secondary legal materials and tertiary legal materials. Results of the Research: From the results of the study, it is explained that supervisory judges and observers are very relevant in the implementation of the current criminal justice system because with the presence of supervisory judges and observers they can carry out direct supervision and observation of court criminal decisions that have legal force and can directly assess whether the decision can be useful. for prisoners or not so that when he is ready to return to the midst of society so that the purpose of the criminal justice system that corrects the perpetrators can be realized, but as long as in Indonesia the implementation of the rights of supervisors and observers is not carried out properly, this is due to the absence of strict sanctions to judges and courts, the lack of regulations and provisions regarding supervisory and observer judges, as well as supervisory and observer judges can be considered as interfering formally with the authority of the penitentiary, therefore the cooperation of the ministry of law is required. and human rights and the judiciary to formulate new regulations for supervisory and observer judges.
(Dis)utopian Landscapes in Don DeLillo’s Fiction
Authors: YANAR Muhsin
Published: November 2023

The concepts of utopia (a good place) and dystopia (a bad place) might be arrived at and developed by one’s contact with the (constructed) reality and comprehension, yet frustration and discontent with it, and one’s pessimism and optimism over a better present and future contingent upon the place and time in which one exists. The former has a long history, whereas the latter is a work in progress. That is, one cannot simply distinguish between the two by asking whether the latter is primarily precautionary and reactive, cautioning us what not to do, whilst the former is proactive, pointing us towards the right direction. Both the former and latter may have similar motives, namely, to demonstrate the dark characteristics of one society by comparing it with another, fictitious culture. Someone’s utopia might alternate dystopia, or many traditional utopias from the past include aspects that modern readers would identify as dystopian. On the other hand, one could argue that dystopia serves as the worst-case scenario, presenting a degraded, collapsing, and/or collapsed society, be it socio-culturally, economically, or technologically, worse than another, yet still hopeful for a drastic change for the better. Utopia could be received as the best-case scenario for people in a society considering its socio-political demise. Shortly, both utopian and dystopian scenarios would fit into an extended framework of contemplations on a catastrophe that would either signal a tremendous shift for the better or result in an apocalyptic nightmare. Drawing on the standpoints of Giles Deleuze and Jean Baudrillard and tracing Don DeLillo’s fiction, this paper seeks to explore the notion of dystopia, the future assumptions that dystopian fiction puts forward, and the challenges and issues it highlights, such as digital surveillance, technological control, the disappearance of individualism, uncertainty, and dread.

Published: November 2023

The operational efficiency of coal-fired thermal power plants designed to utilize designed / standardized fuel and coking plants largely depends on the quality characteristics of the supplied coal products, the main indicators of which are: calorific value, ash content, moisture content, volatile matter yield, sulfur and nitrogen content, particle size distribution. Coal of various grades is mined in Russia, but not more than one third can be classified as the designed fuel. Accordingly, there arises a need to make fuel mixtures with specified parameters. The article justifies the topicality to create a database of qualitative characteristics and indicators of various coal grades. Using the results of analytical review of normative documentation, coal classification options have been developed based on the list of quality indicators specified in the state standard for identification of coals and coal products. Logical structure of the data, entity, relationships between them, attributes and constraints have been defined at the design stage of the database. The type and content of the conceptual model are presented as an ER-model visualized in the form of a graphical notation of the entity-vs-relationship diagram. Based on the analysis performed, ways of transaction and input data sources for the supplied coal characteristics and processing technologies have been defined. Examples of data structure in the models of individual entities and methods to determine their parameters have been provided.
Modeling of flexible value chains based on clean coal processing technologies
Authors: Nikitenko S.M. , Goosen E.V. , Kavkaeva O.
Published: November 2023

The article discusses characteristics of the value chains that have developed in the Russian coal industry. It has been justified that the involvement of the coal industry in the value chain based on promising clean coal processing technologies is becoming a critical task in the context of the imposed sanctions and it is a real step towards new industrialization and transformation of the corner stone sector of the Russian fuel and energy complex. The author's approach to the study of the coal value chains is based on identifying the existing types of value chains in the coal industry, assessing their current resilience and modeling possible directions for upgrading the value chain to increase long-term resilience. A conclusion is made that, despite the currently emerging concept of the carbon-free energy development, the coal industry has all the necessary development prospects due to a differentiated approach to upgrading the value chains based on new flexible technologies and taking into account the specific features of individual companies. Such value chains can be formed at the existing coal mining operations, and in the future it will become possible to create various production facilities for environmentally friendly products based on already existing value chains.
The impact of the coal industry on the economy of Russian regions
Authors: Filimonova I.V. , Provornaya I.V. , Khaykina A.O.
Published: November 2023

The article is a study dedicated to assessment of the economy of Russian regions, taking into account operation of the coal industry. Based on the hierarchical cluster analysis, 80 constituent entities of the Russian Federation were divided into groups according to the aggregated energy, environmental, social and economic indicators. The existence of a relationship between the level of the disease (according to the class of diseases – respiratory diseases, neoplasms, circulatory system disorders, congenital anomalies and malformations) and the volume of pollutant emissions into the atmosphere emitted by the coal industry companies operating in the regions was confirmed. The relationship between the social and environmental, energy and economic indicators has been determined. It is shown that the more developed is the coal industry in the regions, the higher the GRP and per capita incomes are; the higher the emissions are, the higher the incidence or burden on healthcare professionals is. At the same time, the presence of the lowest mortality rate in the leading regions of the coal industry can be associated with a high level of income of the population.

Authors: Plaksin M.S. , Rodin R.I. , Kozyreva E.N.
Published: November 2023

This paper presents the results of the study aimed at solving issues of ensuring the safety of mining operations in the mine development workings in terms of forecasting and controlling gas-dynamic phenomena. The experiment described in the work creates a basis for developing a method to assess gas dynamic activity in the bottomhole part of the coal seam using an innovative device that allows assessing changes in the gas content of the seam along the line from the bottomhole to the geostatic stress zone during the development of preparatory workings. It is proposed to develop a method of current forecast of emission hazard, which will increase the face advance rates and ensure the safety of mining operations, based on assessing methane mobility in the mine working and the new approach of assessing the gas-dynamic hazard of the formation presented in the paper.
Microbubble reagentless hydrophobization of the coal surface
Authors: Patrakov Yu.F. , Semenova S.A.
Published: November 2023

The paper describes methodological features of coal surface hydrophobization the using a microbubble gas-liquid medium to intensify the process of flotation concentration of coal. Air microbubbles were generated using decompression of liquid saturated under air pressure. The influence of water saturation pressure with gas on the size of the bubbles and their stability over time has been established. It is shown that addition of microbubbles leads to formation of an intermediate hydrophobic air layer on the surface of coal, which is the basis for catching bubbles of the flotation size. The results of coking coals flotation using a microbubble gas-liquid mixture are presented. By means of the method of differential particle size analysis, the preferred flotation of fine coal particles < 50 microns in size by micro-bubbles of air was established. It was found that for low-ash coals, the efficiency of reagentless microbubble flotation can be comparable with the results of concentration using traditional petrochemical reagents. In the reagent mode, the micro-bubbles are attached to the oil-hydrophobized surface of small particles with the formation of carbon-air complexes.
Assessment and monitoring of geological risk of а coal deposits development
Authors: Shaklein S.V. , Rogova T.B. , Pisarenko M.V.
Published: November 2023

An approach to the quantitative assessment is considered for the geological risk of a decision-making on the development of a subsurface site based on the results of geological exploration, for the determination of the design solutions feasibility for the construction of a mining plant and for the annual mining development plans feasibility during the operation of the enterprise. The fundamentals of the geometric approach to the quantitative assessment of the confidence of geological indicators models, the use of which allows to avoid the problems arising during geostatistical methods applications in the conditions of coal deposits are set out. The confidence of the study of geological indicators is assessed by the degree of ambiguity of their geometrization results, which is quantified based on preliminary artificial creation of indirect redundant measurements in the exploration well grid. At the stage of coal mining, the evaluation of the significance of the geometrization results ambiguity is carried out with additional consideration of the constantly accumulated experience of mining operations in the mode of monitoring the confidence of resources. The possibility of design solutions implementation is assessed based on a pre-created alternative model of the geological indicator. Such a model is created by “distortion” of the traditional model using an additional negatively influenced indicator values which are in areas of the geometrization ambiguity. In the case the design solution can be successfully implemented in the conditions of the alternative model, the implementation impossibility risk is considered insignificant.

In this context, the article presents an analysis of the thematic collection of scientific literature of the late 19th - first half of the 20th Centuries, exhibited at the Institute of Coal of the Federal Research Center of Coal and Coal Chemistry of the Siberian Branch of the Russian Academy of Sciences. The collection documents the development of comprehensive knowledge on coal and the evolution of its technological processing. Its scientific and information potential provides an insight into the oldest charring processes; the first experiments of industrial coking of hard coal and the evolution of coke furnaces; it also reflects the dynamics of understanding the nature of coal. The methods of comparative analysis and generalization allowed to reveal the information value and representative character of the collection for understanding its role in documenting the development of the coal science.
Face-end supports: current status and development trends
Authors: Korolev M.K. , Malakhov Yu.V. , Nikitenko S.M. , Weiss I.
Published: November 2023

The issues of safe and efficient mining of coal deposits are gaining additional significance as mining and geological conditions become more complicated at deeper license blocks and mining takes of operating mines. In this case, a large-scale network of development workings is created, as well as their interfaces, which are characterized by a complex configuration, and in the areas of their construction, the formation pressure is manifested to the greatest degree. It is noted that mechanization of operations at the interfaces of the faces and adjacent mine workings is a defining factor in the efficient use of the powered mining complexes for coal mining. The article presents a patent collection formed by the authors, consisting of patent families related to the interfaces of the mine workings, from which the patent families were selected that contain the designs of powered face-end roof supports. The paper justifies the trends in development of the face-end supports that include increasing reliability of all the elements and units; increasing stability; integration into automated mining complexes; optimization of manufacturing costs. The authors note the tendency to develop the design of face-end supports of the walking type, which is associated with their main feature, i.e. the possibility of permanent roof support during the face advance to elimination of the effect of the roof "hanging about". This made it possible to fully justify the principle layout of a perspective design of the face-end support. As the result, a possible scope of application is justified for the mechanized walking roof support to maintain the interfaces of the development workings and the working faces.
Mayo Cardiac Intensive Care Unit Admission Risk Score (M-CARS) validation test to assess mortality during treatment in Cardiovascular Care Unit (CVCU) patients at Haji Adam Malik Hospital
Authors: Siahaan Basten Jeremiah
Published: November 2023

Abstract

Background: Approximately 85% of all in-hospital deaths occur in Cardiovascular Care Unit (CVCU) where M-CARS will be an important starting point for development of CVCU-specific mortality risk prediction models.

Aim: This research aims to assess M-CARS validation to assess mortality during treatment in CVCU patients at Haji Adam Malik (HAM) General Hospital.

Methods: This research is a prospective research that examines M-CARS score validity as a predictor of intra-hospital mortality in patients treated at CVCU HAM General Hospital Medan from September 2021 - January 2022. If correlation test results show a significant relationship, cut-off value M-CARS score will be taken using ROC (Receiver Operating Characteristic) curve analysis, then analysis of M-CARS score diagnostic value will be carried out according to cut-off value obtained to predict mortality during hospitalization. Then Hosmer-Lemeshow test was carried out to assess suitability of logistic regression on risk prediction assessment within population that being assessed.

Results: M-CARS had a very good discriminatory ability (AUC 0.93) to predict intrahospital mortality. The calibration value using Hosmer Lemeshow test (R2 = 0.982; p = 1.516; p>0.05) shows that there is no significant difference between observed and expected mortality rate by two scoring systems therefore considered as accurate.

Conclusion: M-CARS is valid to be used in assessing risk of mortality events during CVCU treatment at H. Adam Malik Hospital Medan.

Keywords: Mortality, Cardiovascular Care Unit, Mayo Cardiac Intensive Care Unit Admission Risk Score, Braden Score.
Making Voltaires out of Bureaucrats? Revisiting the Policy of Counter-Enlightenment
Authors: Smolin Oleg N.
Published: November 2023

The article discusses the legal and regulatory aspects of enlightenment activities within the context of the socio-cultural objectives of contemporary Russian educational policy. The author examines social and education-policy factors that underscore the need for extensive enlightenment efforts in the country. One of these factors is the increasing pragmatization of attitudes towards knowledge, leading to a decline in the cultural literacy of the population. Among the manifestations of this issue is the undervaluation of the importance of fostering a well-rounded cultural identity, giving precedence to a “competency-based approach.” Educational standards are geared towards skill and ability development while minimizing the significance of general education subjects. The author also highlights the challenges associated with the growing impact of information technology on the intellectual development of society. These factors necessitate the development of federal legislation to support enlightenment in Russia. However, the existing legal and regulatory framework for enlightenment activities contradicts the values of Russian society and the traditions of domestic enlightenment, effectively turning government bureaucrats into the primary enlighteners. The author analyzes specific legislative clauses that establish cumbersome bureaucratic procedures, which essentially make free enlightenment impossible. Government agencies are burdened with overwhelming responsibilities to monitor enlightenment activities. The dangers of involving citizens in oversight of enlightenment efforts are emphasized, as this poses risks of reviving a culture of denunciation. Enlightenment in Russia requires state support, not artificial constraints. The author substantiates the thesis that enlightenment activities should focus on personal development, not merely on training specific competencies.

The possibility of low-temperature in-situ synthesis of (Ti, W)C ceramics from plasma-chemical nanopowders of tungsten carbide and commercial micron-sized titanium carbide powders has been demonstrated. Sintering/synthesis of WC – (25, 50, 75) wt. % TiC ceramics was carried out by spark plasma sintering (SPS) by heating powders at a rate of 50 °C/min in vacuum under conditions of application of a voltage of 70 MPa, to a temperature of more than 1200 °C. It has been established that the synthesis proceeds most efficiently in nanopowders with the addition of 50 and 75 wt. % TiC. It is shown that the joint application of plasma-chemical synthesis of nanopowders and the SPS method makes it possible to obtain fine-grained ceramics with increased density and satisfactory mechanical properties (Vickers hardness 17 – 18 GPa, minimum crack resistance coefficient according to Palmquist ~ 3 MPa·m1/2).

This article focuses on the process of producing ceramics based on the commercial Si3N4 powder of the various dispersions (< 5 μm and < 1 μm) by spark plasma sintering (SPS). The powder mixtures of 97 wt. % Si3N4 + 3 wt. % additives of the Y2O3 – Al2O3 composition were synthesized by the Pechini method. The SPS technology was used to obtain the ceramic samples of ∅ 20 mm. Sintering was carried out in a vacuum at the heating rate of 50 °C/min and the load of 70 MPa until the shrinkage end. The microstructure and the phase composition of the ceramic samples were investigated. Mechanical properties were measured: Vickers hardness, Palmquist fracture toughness, flexural strength according to the B3B (Ballon-Three-Balls-Test) method. Tribological tests were also carried out. It was established that the lower the dispersion of the powder mixtures based on Si3N4, the lower the shrinkage end temperature. The relative density achieved is 96 %. The ceramics based on Si3N4 powder with the dispersion of <1 µm are difficult to machine, characterized by the hardness of 19.0 ± 0.7 GPa and the crack resistance of 5.1 ± 0.4 MPa·m1/2. The flexural strength of the ceramics evaluated by the B3B method depends on the dispersion of Si3N4 powder and is more than 2 times higher for the ceramics based on the commercial Si3N4 powder with the dispersion of <1 μm.

The effect of irradiation with 132Xe27+ ions (167 MeV) at angles of 20°, 30°, 60°, and 90° to the tape surface on the critical parameters of second-generation superconducting tapes based on the SuperOx GdBa2Cu3O7–x compound has been studied. The dependences of the critical current (Ic) at T = 77 K in the intrinsic magnetic field and the critical temperature (Tc) on the ion irradiation fluences at different irradiation angles are obtained. At all studied irradiation angles, a small (up to ~ 5 %) increase in the critical current of HTSC tapes is observed in the fluence range from 3.4·108 to 5·109 ion/cm2. The radiation resistance of a superconductor to ion irradiation is determined as a function of the irradiation angle. To determine the radiation resistance of the tape, the threshold irradiation fluence Φth was measured, at which the critical current tends to zero. The dependence of Φth on the irradiation angle α is well approximated by the formula: Φth = Φ0 + A·exp(–α/t).

Foundry alloys based on γ′Ni3Al have a lower density, a higher melting point and resistance to oxidation, a higher ceiling of operating temperatures than modern heat-resistant nickel alloys (ZhNS). The article discusses the features of the electronic structure and crystallization of domestic (VKNA type/VIN) and the most advanced foreign (γ′+γ) low-alloyed alloys (type IC) based on γ′Ni3Al, experimental data on the nature of structures formed during directed crystallization of alloys with different types of alloying, on the nature of the distribution of components in γ′Ni3Al and γNi phases and structural components in the cellular-dendritic structure of single crystals with crystallographic orientation are presented 〈111〉 and 〈001〉. The effect of heat treatment in a wide range of temperature-time parameters on the microstructure, distribution of alloying elements and mechanical properties of alloys of the VKNA type is investigated. A comparative analysis of the effect of temperature and duration of heat treatment and the cooling rate after heat treatment on the heat resistance of alloys showed that, unlike other Ni3Al-based alloys, for single crystals made of economically alloyed alloys of the VKNA type and parts made of them (uncooled working blades of aviation gas turbine engines, nozzle apparatuses, jet nozzle spacers and other parts a short-term maintenance (1150 °C / 1 h) is necessary and sufficient to relieve casting stresses. The alloys demonstrate high heat resistance at 1100 – 1200 °C and the ability to withstand temperature drops up to 1250 – 1300 °C for a short time.

The effect of heat treatment (diffusion annealing, quenching, low-temperature and high-temperature tempering) on the structure, phase composition and corrosion resistance of high-entropy 35 Fe – 30 Cr – 20 Ni – 10 Mo – 5 W and 30 Fe – 30 Cr – 20 Ni – 10 Mo – 10 W alloys has been studied. High-entropy alloys of the Fe – Cr – Ni – Mo – W system with different concentrations of tungsten were obtained by sintering mechanically alloyed powders in a vacuum furnace. It was revealed that the total and pitting resistance of the obtained high-entropy alloys to aqueous solutions of NaCl is higher than that of industrially produced austenitic corrosion-resistant steel 316 L used in the oil and gas industry.
