Abstract
Automotive and aircraft industries are advancing swiftly, creating a constant need for innovative and trustworthy materials. Aluminum composites (aluminum matrix composites [AMCs]) exhibit enhanced mechanical and tribological behaviors when contrasted to their conventional equivalents and as a result have superior potential to be widely accepted for automotive and aircraft engineering and other component applications. This study aims to provide a thorough and critical analysis of the most recent research initiatives concerning the processing, characteristics, and applications of AMCs. It covers the recent advancements in the aluminum-based composites reinforced with SiC, TiC, and graphene, fabrication methods, and mechanical properties of AMCs. Graphene nanoplatelets are many times stronger and yet lighter than steel and other metals, and thus a good contender for reinforcing them. However, the homogeneous distribution of graphene into the metal or aluminum is a challenging aspect for material researchers. The fabrication techniques for AMCs for achieving homogeneous distribution of graphene are critically reviewed. The mechanical properties, specifically microhardness, wear behavior, and tensile strength of aluminum-based composites, are reviewed and analyzed. Finally, a way forward for fostering further development in this area has been discussed.
The current status of diversity among physician assistants in surgery: A systematic review
Authors: Sherer Erin L. , Reed Kathryn 
Published: November 2023

Abstract
It is difficult to achieve diverse representation within surgical settings, including within the ranks of physician assistants (PAs) despite research indicating that diversity improves patient outcomes and experience and benefits the workplace. The aim of this systematic review was to evaluate interventions used to support diversity among surgical PAs. Databases including PubMed (MEDLINE), Web of Science, SCOPUS, CINAHL, and Cochrane Database of Systematic Reviews were searched for publications that described interventions for increasing underrepresented in medicine and gender diversity among surgical PAs. While 20 studies were identified, none met the inclusion criteria. The absence of literature on surgical PAs led to an exploration of research conducted among surgeons, nonsurgical PAs, and PA students. While not directly applicable, results from these studies offered valuable insights into factors that impact diversity as well as strategies that foster diversity. Factors such as gender bias, discrimination, and harassment may contribute to lower numbers of underrepresented groups working in surgery. Efforts to support increased diversity include recruitment, leadership support, and mentorship programs. This systematic review highlights the need for further research to foster diversity among PAs working in surgery. While existing surgical literature offers some contextual insights, future studies on and increased attention toward this topic will improve inclusivity and create a more equitable healthcare system.
How the police (over)use explicit apology language to manage aspects of their identity
Authors: Friskney Ruth 
Published: November 2023

Abstract
Public and academic debate suggest a perception that institutions such as the police may be reluctant to apologise or ineffective when they do. This article takes the unusual step of considering the apology culture of the institution potentially offering apology as a crucial step in identifying possible barriers to change in institutional practice. I have analysed explicit apology language in letters written by Scottish police to individuals as a final stage in responding to their complaints about the police. Rather than police reluctance to apologise, I found the police potentially overusing apology language, in the sense that explicit apology language was consistently used where evidence both had and had not been found that the police were at fault. The grammatical construction of the explicit apology language differed between these two contexts. I conclude that police politeness culture includes an empirical norm to use explicit apology language in response to public complaints regardless of the outcome of that complaint, as part of their identity as a public service institution. Tension between this empirical norm and another aspect of police identity, as a law enforcement institution, is managed by a systematic grammatical distinction in apology language patterning with the complaint outcome.

Abstract
As a new type of environmentally friendly building material, cemented sand and gravel (CSG) has advantages distinct from those of concrete. Compressive strength is an important mechanical property of CSG. However, his method of testing is mainly by doing experiments. For this reason, a deep learning algorithm, long short-term memory (LSTM) model, was proposed to predict the compressive strength of CSG by using four input variables, namely cement content, sand rate, water-binder ratio, and fly ash content, with a total of 114 sample data. Three metrics – coefficient (R
2), root mean square error (RMSE), and mean absolute error (MAE) – were used to evaluate the model’s performance, and the predicted results were compared with the traditional machine learning algorithm, namely the random forest (RF) model. Finally, SHapley Additive exPlanations can be combined to explain the contribution degree of each input feature in the machine learning inquiry model to the prediction results. The results show that the prediction accuracy and reliability of LSTM are higher. The LSTM model has R
2 = 0.9940, RMSE = 0.1248, and MAE = 0.0960, while the RF model has R
2 = 0.9147, RMSE = 0.4809, and MAE = 0.4397. The LSTM model can accurately predict CSG compressive strength. Cement and sand rate contribute more to the predicted results than other input characteristics.
Alternative Industrial Chrome-Free Alumina-Based Bricks for Copper Alloy Melting Furnaces

Published: November 2023

Abstract
In this study, the corrosion resistance of alumina-based bricks against the slag of copper alloy melting furnaces was investigated. Four commercial chrome-free alumina bricks have been studied. Bulk density and apparent porosity measurements and phase analysis of the bricks were performed. The most important property, the slag corrosion resistance, was evaluated at the temperature of 1,200°C for 2 h. The microstructures of the bricks, their penetration depth, and corrosion index were evaluated. The results showed that two bricks showed acceptable corrosion resistance against the slag. The low corrosion index of these bricks was attributed to their aluminosilicate phases (sillimanite, or andalusite) and lower phosphate bonding; however, the problematic matter was the silicate phase, which showed lower resistance against the penetration of slag. It was observed that the aluminosilicate phase can improve the corrosion resistance through the reaction with slag, whereas the presence of large alumina aggregates can restrict the penetration of slag.

Published: November 2023

Most topical preparations are meant to be applied to the skin and therefore basic knowledge of skin and its physiological function and biochemistry is very important for designing topical formulations. Sweat and fatty acids secreted from sebum influence the pH of the skin surface. It is advocated that the acidity of the skin helps in limiting or preventing the growth of pathogens and other organisms. One promising avenue is the use of herbal gels, which harness the power of natural compounds derived from plants to combat microbial infections. The aim of the study is to formulate and evaluate antibacterial gel containing Pongamia pinnata. Three formulations were developed by using suitable polymer(carbopol 934p). Developed formulations of herbal gel were evaluated for the physico-chemical parameters such as pH, viscosity, absorbance. This led to an outcome of the formulation of stable herbal gel possessing potent antibacterial activity.Three formulations were developed by using suitable polymer (carbopol 934p). Developed formulations of herbal gel were evaluated for the physico-chemical parameters such as pH, viscosity, absorbance.
The Generation of Free Russia
Authors: Vasiliev V.V. 
Published: November 2023

In the article, the author reflects on the generation of the Moscow nineties starting from personal memories and his own philosophical career. It is argued that it was the generation of the nineties with the greatest consequences for themselves that relieved the experience of Russia&#x27;s transition from totalitarianism to freedom in the late 80s – early 90s of the XX century. The author, in particular, argues that this experience is responsible for the individualism characteristic of many representatives of this generation. The article discusses the situation at the Faculty of Philosophy of Moscow State University at the turn of the 90s, the achievements of Moscow philosophers from the generation of the nineties and a number of trends and problems of modern Russian philosophy.
Ethnopolitical Conflicts in Transit Time as Moral and Psychological Phenomenon (Attempts of Diagnosis and Treatment)
Authors: Obolonsky A.V. 
Published: November 2023

The article is devoted to an analytical review of psychoanalytic and other psychological approaches to the description and overcoming of ethnopolitical conflicts in Russia and other post-Soviet countries. The materials of the multinational research group International Dialogue Initiative and the scientific works of its members are widely used. The concept of psychological trauma is considered in detail, as well as the phenomenon of post-traumatic syndrome inherent in societies of the transit period. National enmity is considered on the basis of a number of examples through the prism of the psychoanalytic concept of “chosen” trauma. Considerable attention is paid to the psychological aspects of the treatment of ethnotrauma. In this regard, the positive aspect of the attitude to the past wars is considered as a common, but already experienced, mourned and buried trauma, which, from the point of view of psychoanalysis, contributes to its adaptive experience and transformation in the public consciousness, and, ultimately, reconciliation between former enemies. One of the key factors for this is the concept of the universal human need to have both enemies and allies developed by the outstanding psychoanalyst V. Volkan.
Towards a General Theory of the Crisis of the Empire
Authors: Buldakov V.P. 
Published: November 2023

The author claims that the roots of the revolution lie deeper than allowed by the mentality of the Enlightenment. It should be considered in the paradigm of historical cyclicity, which produced especially large-scale and painfully affects to complexly organized imperial systems. As applied in Russia in the 17th – 20th centuries, the systemic crisis, with varying degrees of intensity, went through the following stages or levels: ethical, ideological, political, organizational, social, ochlocratic, recreational. It was a synergistic process, the chaotic course of which, in the final analysis, turns out to be dependent not on ideology and politics, but on the psychology of the masses. Its result was due to the fact that the masses, having exhausted all the possibilities of getting out of a critical situation, turned to historical experience, that they see. In Russia, it is associated mainly with the paternalistic type of worldview.
Cognition of the Alien as a Way of Self-Knowledge: The West, India, Russia (an Attempt at Xenology)
Authors: Lysenko V.G. 
Published: November 2023

The article proposes a philosophical concept of “xenology” (the science of alien) as a way of knowing oneself through the knowledge of the culturally and civilizationally alien as a way of forming identity “self-construction”. The author formulates four principles of xenology. First: we can realize our Self only through the “not-Me”, the other, the alien. Second: civilizational, cultural and national identity is actualized when confronted or in conflict with someone else&#x27;s identity. For example, the Greeks realized themselves as “political animals” only against the background of “barbarians”. Third: our “self-construction” is already embedded in the very model of someone else. Fourth: the image of a stranger in a particular culture can serve as an important indicator of its level of development (tell me what your alien is, and I&#x27;ll tell you what you are), as well as an instrument of both self-affirmation and self-understanding, self-esteem, self-criticism, and a stimulus for self-improvement. As an illustration of these principles, the article offers nine models of the alien, highlighted on the material of the cultural history of two civilizations – European and Indian as well as in connection with the analysis of modern Russian reality. The models develop into a sequence that is determined by the movement from the biological to the social and cultural: xenophobic (ethological), mythological, model of antipodes, model of races, model of the initial state, passeist model, model of the natural state, heterotopic and universalist models. We humans, as a biological species, have a fear of the alien, but we rise above this fear with the help of social and cultural mechanisms that allow us to expand and deepen our identity from family, collective, ethnos, nation to the entire human race (presumption of humanity). In the conclusion of the article, the author examines the manipulation of “friend-foe” identities based on the xenophobic model in modern Russian political discourse.

The relevance of the research is caused by the lack of study of gas hydrates and asphaltene-resin-paraffin deposits formation in the borehole space. The properties of the organic deposits formed significantly depend on conditions of their formation. Accordingly, more accurate understanding of principle of deposits formation allows predicting their agglomeration and selecting effective ways to combat the deposition of gas hydrates and asphaltene-resin-paraffin deposits. In addition, information presented in the article makes it possible to evaluate the effect of the main factors affecting the conditions of gas hydrates and asphaltene-resin-paraffin deposits formation. There is an opportunity to point out the most important factors, which can be controlled by changing the parameters of the downhole equipment. These studies can help to optimize selection of downhole equipment parameters in the conditions of organic deposits formation. The main aim of the research is to analyze the conditions of gas hydrate and asphaltene-resin-paraffin deposits formation in production well; to analyze the results of previous studies on the factors affecting the formation of gas hydrates and asphaltene-resin-paraffin deposits in the borehole space. Objects: factors affecting formation of gas hydrates and asphaltene-resin-paraffin deposits on inner surface of the oilfield equipment. Methods: literature review of publications in peer-reviewed journals; analysis of the results of previous studies, formulation of main ideas and trends, identifying gaps and shortcomings of existing researches. Results. The main mechanisms of gas hydrates and asphaltene-resin-paraffin deposits formation on inner surface of the oilfield equipment are described. A review of previous studies devoted to the analysis of formation mechanisms of asphaltene-resin-paraffin deposits and gas hydrates is presented. The analysis revealed gaps and assumptions in the theory of formation of gas hydrates and asphaltene-resin-paraffin deposits, which require further study of their formation principles. The main factors that depend on the operation of downhole equipment, as well as affecting the formation of organic deposition are analyzed: thermal baric conditions, gas content, throttling, watering, molecular phenomena. These factors are summarized in separate tables.

This article aims to analyze residential segregation by race (racial segregation) and income (economic segregation) in Brazil and explore its relationship with socioeconomic and socio-spatial factors. Residential segregation was assessed using the dissimilarity index based on the 2010 demographic census and considering urban census tracts since segregation is sociologically considered an urban problem. The results for racial segregation showed that it is more evident in cities in the South and Southeast of Brazil and mainly affects the self-declared black population. The approach used to calculate economic segregation involved examining the income level of different low-income groups. Therefore, we consider families that earned between 0 and 1 minimum wage as the group with the greatest social vulnerability. We did not find significant correlations between racial and income segregation indices with aspects such as urbanization (urban population size). Finally, we present the racial segregation indices stratifying families by income thresholds for the 27 Brazilian capitals and conclude that per capita household income is a preponderant factor for the segregation of the poorest, especially in families whose residents self-identify as black.
