Abstract
We study the formation and evolution of dark galaxies using the IllustrisTNG cosmological hydrodynamical simulation. We first identify dark galaxies with stellar-to-total mass ratios, M

tot, smaller than 10−4, which differ from luminous galaxies with M
*/M
tot ≥ 10−4. We then select the galaxies with a dark matter halo mass of ∼109
h
−1
M
⊙ for mass completeness and compare their physical properties with those of luminous galaxies. We find that, at the present epoch (z = 0), dark galaxies are predominantly located in void regions without star-forming gas. We also find that dark galaxies tend to have larger sizes and higher spin parameters than luminous galaxies. In the early universe, dark and luminous galaxies show small differences in the distributions of spin and local environment estimates, and the difference between the two samples becomes more significant as they evolve. Our results suggest that, unlike luminous galaxies, dark galaxies tend to be initially formed in less dense regions and could not form stars because of heating from cosmic reionization and few interactions and mergers with other systems containing stars. This study based on numerical simulations can provide important hints for validating dark galaxy candidates in observations and for constraining galaxy formation models.

Abstract
A key objective for the future exploration of the icy moon Enceladus is the characterization of the habitable conditions in its internal ocean. Radio science instrumentation on board a spacecraft in a low-altitude orbit about Enceladus would enable gravity measurements that are fundamental to providing constraints on its internal structure. We present here the concept of operations and expected results of the gravity investigation for a New Frontiers–class mission. Numerical simulations are carried out to determine the gravity field in spherical harmonics to degree and order 30 and the Love number k
2 and its phase. By combining Enceladus’s shape measured by Cassini and the geophysical constraints obtained through the processing of the simulated radio science data, a Bayesian inference network is used for the interior model inversion. Our results indicate that the gravity investigation would enable tight constraints on core radius and density, ocean depth and density, and ice shell rigidity. By assuming a high core rigidity and a preliminary modeling of dissipation in the ice shell, our interior model inversion also yields information on the ice shell viscosity. Further data on the hydrosphere properties might be gathered through optical navigation data by accurately measuring Enceladus’s orientation model.
Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O i] Observations: Implications for the Source of Icy Grains in Cometary Comae
Authors: Huffman Mikayla R. , McKay Adam J. , Cochran Anita L. 
Published: February 2024

Abstract
The study of cometary composition is important for understanding our solar system's early evolutionary processes. Carbon dioxide (CO2) is a common hypervolatile in comets that can drive activity but is more difficult to study than other hypervolatiles owing to severe telluric absorption. CO2 can only be directly observed from space-borne assets. Therefore, a proxy is needed to measure CO2 abundances in comets using ground-based observations. The flux ratio of the [O i] λ5577 line to the sum of the [O i] λ6300 and [O i] λ6364 lines (hereafter referred to as the [O i] line ratio) has, with some success, been used in the past as such a proxy. We present an [O i] line ratio analysis of comet 45P/Honda-Mrkos-Pajdušáková (HMP), using data obtained with the Tull Coudé Spectrograph on the 2.7 m Harlan J. Smith Telescope at McDonald Observatory, taken from UT 2017 February 21–23, when the comet was at heliocentric distances of 1.12–1.15 au. HMP is a hyperactive Jupiter-family comet (JFC). Icy grains driven out by CO2 sublimation have been proposed as a driver of hyperactivity, but the CO2 abundance of HMP has not been measured. From our [O i] line ratio measurements, we find a CO2/H2O ratio for HMP of 22.9% ± 1.4%. We compare the CO2/H2O ratios to the active fractions of the nine comets (including HMP) in the literature that have data for both values. We find no correlation. These findings imply that CO2 sublimation driving out icy grains is not the only factor influencing active fractions for cometary nuclei.
La compensation écologique permet-elle vraiment de tendre vers l’absence de perte nette de biodiversité ?
Authors: Padilla Brian , Gelot Salomée , Guette Adrien , Carruthers-Jones Jonathan 
Published: February 2024

Depuis 2016, le droit français poursuit un objectif de non perte nette de biodiversité en imposant aux projets ayant des incidences sur la biodiversité d’éviter, de réduire, puis de compenser ces incidences. Les mesures compensatoires doivent générer des gains écologiques suffisants, ce qui suppose qu’elles soient réalisées sur des sites en mauvais état écologique. Cet article analyse le contexte écologique dans lequel ont été réalisées 1153 mesures compensatoires, entre 2017 et 2021, sur le territoire hexagonal français. En utilisant des données de la "naturalité potentielle de France métropolitaine", nous comparons d’une part les scores d’intégrité biophysique des sites choisis et d’autre part les scores de qualité écologique incluant un indice de connectivité du paysage autour des sites, par rapport aux scores nationaux. Nos résultats montrent que 64 % de la surface des sites de compensation se situe sur des espaces où le score d’intégrité biophysique est supérieur à la médiane française, et que 40 % se situe sur des espaces où il est supérieur au dernier quartile. En revanche, la majorité des sites de compensation se trouve dans des paysages présentant une qualité écologique inférieure à celle du territoire hexagonal. Ces résultats suggèrent que la stratégie de localisation des mesures compensatoires ne vise pas prioritairement à générer un gain écologique important, mais répond à d’autres contraintes économiques et foncières. Cela questionne l’efficacité de la compensation à tendre vers l’absence de perte nette de biodiversité.
Trois pistes d’exploration de l’écoformation : retour sur un trajet de recherche
Authors: Galvani Pascal 
Published: February 2024

Cet article présente un trajet de recherche qui témoigne de la pertinence toute particulière des recherches et des pratiques en écoformation au regard des crises écologiques actuelles. Trois grandes pistes d’exploration se dégagent. La première est celle du dialogue avec les cultures amérindiennes. J’analyserai d’abord comment mes expériences dans des contextes amérindiens aux États-Unis et au Québec ont transformé ma relation au monde et m’ont amené à développer une démarche de co-formation interculturelle. La deuxième piste est celle d’une recherche-action pour expérimenter la transdisciplinarité et l’épistémologie de la complexité dans les pratiques universitaires. Cette expérience a contribué à une écologisation de la formation universitaire en reliant les savoirs et la vie. La troisième piste est celle de la réflexion sur les nouvelles pratiques d’auto-éco-formation. De nombreuses pratiques deviennent des voies de connexion au monde vivant : marche itinérante, pistage, école en forêt, aquarelle en plein air, etc. Ces différentes approches montrent le potentiel heuristique du concept d’écoformation pour accompagner les mutations vitales qui s’opèrent tant au niveau personnel, social, que culturel.
Social Media as a Tool for Political Self-Presentation: An Analytical Experience of Russian Political Party Representatives' Profiles
Authors: Soldatenkov Ivan V. 
Published: February 2024

During the first decades of the 21st century, social media has emerged as one of the most significant means of mass communication. Concurrently, the technological features of new media have transformed communication processes. This article addresses the issue of how politicians’ self-presentations are changing due to their adaptation to the unique aspects of communication on social networks. The study aims to identify the self-presentation strategies employed by Russian politicians in online interactions.
The research involved content analysis of posts on the personal pages of politicians on the VKontakte social network. The sample included 375 publications across five pages (75 for each), belonging to politicians who are members of the governing bodies of the parties “United Russia” (D. A. Medvedev), LDPR (L. E. Slutsky), Communist Party of the Russian Federation (G. A. Zyuganov), “Just Russia—Patriots—For the Truth” (S. M. Mironov), and “New People” (A. O. Tkachev). Using cluster analysis and multidimensional scaling, models of self-presentations were developed, and their common and individual features were identified. The study revealed that the impression management strategies used by Russian politicians in social media are characterized by a tendency to showcase professional aspects of their personalities, create a vivid image of the “enemy”, and exhibit a low degree of interactivity.
Virtual Romans and Virtual French: Recontextualization of Political News in the Format of Playing with History
Authors: Miziryak Nadezhda A. 
Published: February 2024

The oversaturation of information flows and the competition among diverse viewpoints underscore the significance of every message that captures the audience’s attention and provokes discussion. Thus, exploring new formats and methods for attracting attention to news agendas, analyzing innovative persuasion techniques, and scrutinizing gaps and overlooked aspects in discussion platforms become particularly crucial in cutting-edge media studies. One such innovative format for news perception and discussion can be found in virtual pseudo-historical public pages on VK. These pages engage with the real socio-political news agenda, stylized as events from different eras such as ancient Rome and 19th-century France.
The aim of our research is to identify techniques for attracting attention, encouraging discussion, and persuading audiences in these selected public forums. We analyzed the characteristics of recontextualized news presentations, including the transposition of time and place, renaming key figures and technologies, and the nuances of internal humor on these public pages. A primary focus of these pages is political news, particularly the Russian-Ukrainian crisis, which is metaphorically represented through the lens of the Punic or Napoleonic wars. This juxtaposition of historical and contemporary perspectives enables users to interpret the political agenda differently. This pseudo-historical linguistic play and unique humor bypass critical perception filters, and once readers accept the internal logic of the public pages, they also tend to accept the narratives presented. The ability to comment on posts allows users to engage in the same narrative style, broaden the scope of news discussions, and involve their friends by reposting to their own pages.
Analysis of Public Discussions in Social Media as a Method for Studying Social Issues
Authors: Judina Darja I. , Riazantseva Angelina V. 
Published: February 2024

The study of social problems using the analysis of the public sphere gained scientific legitimacy with the constructivist approach during the era when television was the predominant medium. The advent of social media has transformed the public space, altering the way in which discussions concerning social issues are organized. This article examines the advantages and limitations of constructivism in studying social problems and the elements constituting public discussions on social media. We searched whether analyzing public discourse could reveal the persistence of social issues. To exemplify the use of this method for studying discussions on social media, we analyzed how network users discussed the issue of personnel shortages, from November 2022 to February 2023. During this period, the most pressing issues proved to be shortages of professionals in healthcare, housing and communal services, secondary education, transport, defense industry and IT sectors.
The research indicates that a crucial marker of a persistent social problem in people’s daily lives is the involvement of “ordinary” citizens as speakers who draw significant attention to the issue. This finding corroborates the democratizing impact of social media on the structure of the public sphere.
Corporate Cancellation: The Odyssey of the “Myth of 922” between Academic and Ideological Discourses
Authors: Ovchinnikov Alexander V. 
Published: February 2024

Methodological problems of the analysis of the phenomenon of “cancellation culture” are investigated. It is stated that “cancellation” was characteristic of all stages of history, but the actual “cancellation culture” could only arise with the development of civil society and mass media. It is proved that the concept of “corporate cancellation” is more acceptable for states of a transit of democracy type of development, when the main actors of the “cancellation” of an individual, social group or views (scientific, religious, etc.) are political elites. In order to develop the proposed theoretical approach, the extensive material of the “Myth of 922” case was analyzed. The following items were recorded: “cancellation” in the mass media of the academic version of the events of 922; cardinal changes in the historiographical field; intercorporate interaction of political elites and academic structures, which eventually led to the official celebration of the anniversary of the “1100th anniversary of the adoption of Islam by Volga Bulgaria”; complex strategies of behavior of individual researchers who tried to use the “weaknesses” of the “myth of 922” to accumulate their own symbolic capital, but very rarely turned to the discourse of the “cancellation culture”. The theoretical outlines of “corporate cancellation” proposed in the article can be useful for a better understanding of the known facts of “cancellation” in the Soviet and contemporary Russian history.

Authors: Jadhav Anil Govindrao , Huddar Shreedevi 
Published: February 2024

Background: Khalitya (hair fall) is a common disease in the present era associated with an unhealthy diet and lifestyle. Khalitya involves the Shiro as the Roga Adhishtana (Site of Disease). Shiro Abhyanga with Taila Kalpana is effective for all Shirorogas. Bhrungaraja has been explained as Keshya in Dhanwanthari Nighantu and Kaiyyadeva Nighantu. Hence, by taking the reference as Keshya, Bhrungaraja Taila can be made using Sneha Paka Vidhi and given to Shiro Abhyanga and Nasya Karma in cases of Khalitya. Objectives: To evaluate the comparative efficacy of Bhringraja Panchanga, Taila Abhyanga, and Nasya in different routes of administration. Materials and Methods: Shiro abhyanga was done every day with a similar method of massaging as mentioned in the classics with Bhrungaraja Taila for 15 days of duration in one group, and Marsha Nasya was administered with Bhrungaraja Taila for 7 days in the other group. Clinical signs and symptoms were given suitable scores according to their severity and assessed based on relief after treatment. The results with a P < 0.05 were considered statistically significant in this study. Results: The overall assessment of the results showed that the subjects in Group B treated with Bhrungaraja Taila Marsha Nasya responded well compared to the subjects in Group A treated with Bhrungaraja Taila Shiro Abhyanga. Interpretation and Conclusion: The clinical study revealed that the drug possesses the efficacy of Bhrungaraja Taila in Khalitya (hair fall), and thus the efficacy of Bhrungaraja Taila in this study is justified with the help of Shiro Abhyanga and Nasya Karma.

Authors: Sarma Ramala 
Published: February 2024

Introduction: Research on yoga meditation has shown the effectiveness of meditation in alleviating stress and anxiety. However, its efficacy on Generation Z (Gen Z) pupils, who mostly experience mental stress, remains unknown in many cases. As at the deep root of their stress lies their inability to look at things as they are, meditative practice, and non-judgmental awareness, are useful for them in alleviating stress. The present study focuses on the efficacy of meditation in managing the mental stress of Gen Z pupils. Materials and Methods: Apart from the qualitative analysis of stress and mental health from a yogic perspective through a host of relevant literature, a quasi-experimental study was conducted at Philosophy Department, Nowgong College (Autonomous) Institution on 92 students 18–23 years of age selected through purposive sampling as subjects from three educational institutes of Assam, India, from October 2022 to December 2022. Participants received meditation classes online for 90 days. Data collected through the Stress Scale questionnaires developed by Dr. M. Singh was analyzed with statistical tools and t-tests. Results: The study showed a positive change in the stress level of the participants as a result of meditation practice. The observed results are – t = 8.18, P = 1.646*10-12 or 0, P ˂ 0.001. Conclusions: Meditation practice is an effective way to release the mental stress of Gen Z pupils. The practice may be recommended as a regular use for them.
Utility of Shadangapaniya in Various Ailments – A Review
Authors: Sajeesh  , Thakur Balaji , Prasad Mahendra , Singh Bhanu Pratap 
Published: February 2024

Introduction: Ayurveda has mentioned many Kalpanas, one among them is Paniya Kalpana (medicated drinking water). It comes under Upakalapana (derivative) of Kwatha (process of medicated liquid). It is regarded as the most beneficial and potent because it is very easy to digest and readily absorbed by our bodies. Dosha (one which governs and maintains the health), Dhatu (fundamental tissues that constitute the human body), and Mala (metabolic end products) are the components of Sharira (human body), which is governed by Agni (digestive fire). In a healthy state, Sharira (human body) maintains regular physiological functioning; when it is impaired, Sharira (human body) results in various ailments. Shadangapaniya is a special formulation that controls all the aforementioned aspects. Six herbs, including Musta, Parpataka, Ushira, Chandana, Udichya, and Nagara, make up the Shadangapaniya. Materials and methods: The classic Ayurveda literature, including the Charaka Samhita, Sushrutha Samhita, Ashtanga Hridaya, and Bhavprakasha Niganthu books of Dravyaguna Vignana, and other Nighantus. Result and Discussion: Shadangapaniya not only acts on Jwara (fever) but also is useful in various conditions and as well as on various systems. For example, we can give in Rakthapitta (bleeding conditions), Atisara (diarrhea and dysentery), Ati sweda (excessive perspiration), and Trishna (thirst), which will be discussed with references from classical textbooks. Conclusion: Maintaining the equilibrium state of Dosha (one which governs and maintains the health), Dhatu (fundamental tissues that constitute the human body) Mala (metabolic end products), and Agni (digestive fire) is the fundamental goal of all Ayurvedic treatments for ailments. Shadanga Paniya (medicated drinking water made up of six herbs) is a distinctive and popular recipe that preserves the above-mentioned state of equilibrium.

Authors: Hadke Sonali , Penna Madhusudan 
Published: February 2024

The aim of this study is to evaluate the findings of selected articles regarding the effects of the Mind Sound Resonance Technique (MSRT) and to provide a comprehensive review of the benefits of the MSRT. Due to many things such as daily rush, work style, workload, goal fulfillment, increasing stress it creates mental and physical diseases. To prevent these diseases, it is necessary to inform everyone about the effect of MSRT and its benefits. Thus, this manuscript reports on a study of the effects of the MSRT on various group problems and situations. The MSRT is one of the many yoga techniques, which influences the Manomaya Kosha area of the Pancha Kosha. In this technique, use mantra to generate resonance in the body, which mainly works through the Manomaya Kosha to induce deeper relaxation for both mind and body. The results of this study show that practicing the MSRT improves mental health, reduces mental health symptoms, reduces burnout/fatigue, manages occupational stress, increases teacher importance, overcomes mental barriers, improves emotional regulation, and teacher–student relationships as well as increases cognitive performance, reduces anxiety and stress, improves sleep quality, improves mental health, regulates blood pressure, and helps reduce fatigue and pain. Of course, the MSRT works to enhance overall well-being and quality of life.
