Authors: Titaev V. A. , Cherny I. A. , Sokolov B. S. , Titaev D. V. 
Published: December 2024

Introduction. Stone masonry is a structurally heterogeneous (composite) material; therefore, a number of its physical and mechanical characteristics are orthotropic, including the coefficient of linear thermal expansion. The article analyses the coefficient of linear thermal expansion of stone masonry under the conditions of its operation in different temperature and climatic conditions, including different humidity.Aim. To obtain the dependence of the coefficient of linear thermal expansion on masonry humidity at freezing temperatures by comparing the results of studies of wet masonry samples.Materials and methods. The study is based on the data of M.A. Mury published in his work "Temperature deformations of wet brickwork" and some of his previously unpublished data. Regression analysis was used to perform the research.Results. There were obtained graphical and mathematical dependences of the coefficient of thermal expansion of masonry in the form of piecewise linear functions at freezing temperatures, with account of material humidity.Conclusions. The presented dependences can be used in calculations of the stress-strain state of masonry structures with the use of modern program complexes. Published data on the coefficient of linear thermal expansion of masonry show a wide range of their values, which indicates fragmentary research based on the use of ceramic stones from a single manufacturer. Therefore, large-scale research with systematization of the results with a logically justified maximum number of varying parameters of masonry should be carried out, with subsequent amendments to the norms of design and construction of masonry structures based on the results of the research.

Published: December 2024

Introduction. The warranty or predicted service life of the flame retardant coatings, depending on the service conditions, is a crucial parameter in ensuring fire safety. Service life, or durability, can be defined as the ability of the flame retardant coating to resist external influences, i.e., to remain unchanged and retain its efficiency under climatic and various adverse factors. Since full-scale testing of the coatings’ durability is time consuming, accelerated testing methods are relevant.Aim. To test methods for determining the resistance to climatic factors during aging in an open industrial atmosphere (HL1 (cold), UHL1 (moderate and cold macroclimatic regions) according to State Standard 15150-69). In addition, to test the efficiency of coatings of steel building structures under operation on the example of a modern fire retardant coating.Materials and methods. The samples of the flame retardant coating were cyclically aged for 5, 15, and 25 years according to method 6 of State Standard 9.401-2018. The resistance to climatic factors and preservation of flame retardant characteristics during operation was evaluated according to State Standards R 53293-99 and R 53295-2009. The plates made of 08kp and 08ps steel sheets according to State Standards 16523-97 and 9045-93 in the size of 600 × 600 × 5 mm with a flame retardant applied to it from the front side as an anticorrosive primer “DEKOPOKS-FAST” with a dry layer thickness of 80 microns, weather-resistant flame retardant paint “DEKOTHERM-KHROM-R” with a dry layer thickness of 870 microns and finish coating with two-component polyurethane primer-enamel “DEKOPUR-FLEX” with a dry layer thickness of 50 microns.Results. The flame retardant efficiency was found to decrease slightly with increasing number of artificial aging cycles and amount to 12 % downward from the control sample at 224 cycles (25 years).Conclusions. The predicted service life of the investigated coating system in open industrial atmosphere (HL1, UHL1) with preservation of the flame retardant efficiency if all requirements of the technological process of obtaining the coating are met is not less than 25 years.

Entre Kulturkritik et Cultural Studies : une réception « moralisée » de Jean‑Sébastien Bach ?
Authors: Sounac Frédéric 
Published: December 2024

Dans le cadre d’une réflexion sur la réception et l’intermédialité, cet article jette un regard rétrospectif sur une recherche ayant abouti à la publication de l’ouvrage Black Bach ou Qui a peur de Jean‑Sébastien ? Valeurs culturelles et (anti)humanisme. Il s’agit là d’examiner la constitution et l’affermissement de l’autorité de la figure de Bach dans la culture depuis le milieu du xviiie siècle, et surtout son association à des contre‑valeurs : postures violemment anti‑progressistes, bellicistes, ultra‑élitistes ; aliénation de soi et d’autrui, absence d’empathie, socio-pathologie homicide, etc. Un vaste ensemble d’écrits philosophiques, musicographiques, littéraires (incluant nombre de romans policiers et de science‑fiction), mais aussi de films, séries, et représentations de Bach dans la culture « pop », constitue la matière de l’ouvrage. Après avoir évoqué la notion d’imagologie, on s’efforce de situer la démarche utilisée entre une tradition de « critique de la culture » (Kulturkritik) attachée à l’herméneutique des œuvres et des « études culturelles » (cultural studies) plus centrée sur les modalités de la relation esthétique.
Pour une archéologie de la réception par l’image : le cas de Victor Hugo
Authors: Gleizes Delphine 
Published: December 2024

À travers l’exemple de Victor Hugo, l’article analyse les formes de réception par l’image d’un écrivain : illustration du texte, adaptation via des récits en image et bientôt le Cinématographe, autant de représentations interprétatives de l’œuvre, tributaires de médiums et de techniques spécifiques. L’article envisage également la façon dont l’image participe à la représentation et à la réfraction de la vie littéraire qui orchestre la réception, mettant en scène les réactions du lectorat, véhiculant une axiologie spécifique au microcosme artistique : célébrations et condamnations, patrimonialisation, « légendarisation », caricature… En montrant comment l’écrivain lui‑même joue avec ces phénomènes médiatiques, l’article entend pour finir, sur un plan méthodologique, plaider pour opérer un permanent aller‑retour critique entre les pensées modernistes de la réception telles qu’elles se formulent au xixe siècle et les conceptions contemporaines. Qu’il s’agisse des modes de consommation médiatique, des pratiques virales ou bien du traitement des matériaux littéraires et artistiques pour obéir aux logiques d’attraction attentionnelle, la méthode offre alors d’entrevoir la façon dont notre pensée contemporaine de l’intermédialité s’origine dans les gestes créatifs et le discours réflexif qui émergent au xixe siècle.
Variation of Ambient Illumination Across Different Locations: An Impact on Antimyopia Strategy
Authors: Chaurasiya Ritesh K. , Sutar Samir , Gupta Akansha , Chaudhary Rishabh , Saini Rishiraj , Agarwal Pradeep , Khurana Ashi , Chauhan Lokesh 
Published: December 2024

PURPOSE:
To evaluate whether the level of ambient illumination in winter at different locations, time of a day, sun protection, and source position remains optimum (≥1000 lux) for controlling myopia progression.

METHODS:
Illuminance level was recorded for 6 outdoor and 5 indoor locations using factory calibrated digital lux meter and under different measurement conditions. Outdoor locations included “open playground,” “between two buildings,” “between three buildings,” “under a porch facing east,” “under a big tree,” and “under a porch facing west.” Similarly, indoor locations included “rooms with multiple large windows,” “rooms with a combination of light sources,” “room with single artificial light,” “room with multiple artificial lights,” and “canopy covering the buildings.”

RESULTS:
The overall median illumination level across 6 outdoor locations and 5 indoor locations were 1900 lux (803–4300 lux) and 227 lux (82–556 lux) respectively. Indoor locations showed an overall low median illuminance level (<1000 lux) irrespective of the locations and source positions. However, the illuminance level >1000 lux was recorded for “Room with multiple large windows” for specific points of time (10:00–11:00 and 13:00–14:00) in both sunny and foggy weather. The highest illumination level was recorded only in the “open playground” irrespective of various conditions such as time of the day, weather of the day, relative source position, and sun protection.

CONCLUSION:
The ambient illumination level was optimum (≥1000 lux) for antimyopia strategy in winter for maximum outdoor locations. However, children should be motivated to spend their outdoor time during the afternoon (13:00–14:00 h) so that light intensities reaching the eye should be optimum in winter.
Antifungal drug sensitivity testing in clinical specimens from dermatophyte infection using E-strip disk diffusion technique
Authors: Jayaraman Jyothi , Bhat Ramesha M , Babu Ashwini , Anusha Rekam , Dias Meena 
Published: December 2024

ABSTRACT

Context:
The wide range of antifungal agents available poses a difficulty in choosing an effective medication to avoid drug resistance. There is a need for a standard antifungal susceptibility testing method that would guide a practicing dermatologist to prescribe antifungal agents effectively.

Aims:
The aim of the study was to determine the prevalence of each species of dermatophytic infections and to determine the resistance pattern to common antifungal agents.

Settings and Design:
A cross-sectional interventional study was conducted at a tertiary health care center.

Subjects and Methods:
Two hundred consecutive patients diagnosed with dermatophytic infections were examined, and scrapings were sent for 10% potassium hydroxide (KOH) mount examination and culture. Further, antifungal drug susceptibility pattern was tested using the E-strip to determine the minimum inhibitory concentration (MIC) for fluconazole (FCZ), itraconazole (ITZ), clotrimazole, ketoconazole (KTZ), and voriconazole.

Statistical Analysis Used:
Collected data were analyzed by frequency, percentage, standard deviation, mean and Chi-square test, and Fisher’s exact test.

Results:
One hundred and thirty-four samples were found to be KOH mount positive, and 81 samples yielded growth on culture. Trichophyton mentagrophytes was the most commonly isolated species in 32 (39.5%) specimens followed by Trichophyton rubrum in 29 (35.8%) samples. T. mentagrophytes showed the least MIC for KTZ, ITZ, and voriconazole (0.032–1.5 mg/L). T. rubrum was seen to have a MIC in the range of 0.04–2 for ITZ, 0.06–1.5 for voriconazole, and 0.13–0.75 for KTZ and highest for FCZ (0.5–32 mg/L), respectively.

Conclusions:
There is currently no reference method available to test drug sensitivity, and E-test is a simple technique which can be employed for antifungal drug sensitivity testing with less workforce, quick results, and easy interpretation aiding effective treatment of dermatophytic skin infections.
Subgroup growth in free class-$2$-nilpotent groups

Published: December 2024

We describe an effective procedure to compute the local subgroup zeta functions of the free class-

2

-nilpotent groups on

d

generators, for all

d\geq 2

. For

d=4

, this yields a new, explicit formula. For

d\in\{4,5\}

, we compute the topological subgroup zeta functions. We also obtain general results about the reduced and topological subalgebra zeta functions. For the former, we determine the behaviour at one; for the latter, the degree and behaviours at zero and infinity. Some of these results confirm, in the relevant special cases, general conjectures by Rossmann.

Authors: Yap Chee Kong , Leow Chee Seng , Vincent Leong Wing Sum 
Published: December 2024

This study investigates aligning personality traits with business administration roles to enhance efficiency and organizational success, applying Holland's RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) model with the FIKR (Facet, Insight, Knowledge, and Resilience) Profiling Assessment Tool. Using data from 180 respondents, six personality dimensions—Realistic, Investigative, Artistic, Social, Enterprising, and Conventional—were analyzed to evaluate suitability for business administration roles. Key findings reveal a high prevalence of Enterprising and Conventional traits, highlighting strong leadership potential and organizational skills, while Social traits positively influenced team dynamics and client management, emphasizing their role in interpersonal relations. Theoretically, this research advances the understanding of personality-based role alignment, showing how specific traits support core business administration functions and contribute to role effectiveness. These insights allow organizations to refine hiring practices, optimize role assignments, and improve workforce development by aligning employees with roles that match their personality profiles, ultimately supporting enhanced business performance and long-term organizational success.

Ágoras filosóficas en los cuarenta años de la democracia
Authors: Busdygan Daniel 
Published: December 2024

El año 2023 en Argentina, marcado por los 40 años de democracia, coincidió con elecciones y un aumento en la demanda de información política. Este contexto generó un inusual nivel de discusión política en el que se trazaron reflexiones sobre el pasado, las deudas del presente y los desafíos del futuro. En una notable época de cambios a partir de los avances tecnológicos, se han observado cambios radicales en la cultura política y democrática. Allí, la filosofía como disciplina encuentra el escenario propicio y la necesidad de abrirse al diálogo con la sociedad. La experiencia filosófico- pedagógica, Ágoras bonaerenses emerge como un hito histórico al propiciar encuentros filosóficos de estudiantes de filosofía y ciencia política. Estos encuentros buscan trascender las aulas y crear espacios de reflexión filosófica sobre la democracia en el siglo XXI, enfrentando los desafíos de la tecnología y las redes sociales. La filosofía, al justificar su existencia, debe ir más allá de la especialización y abrirse a la sociedad, contribuyendo con argumentos y propuestas para comprender y transformar la realidad democrática. La experiencia de Ágoras bonaerenses destaca la importancia de la filosofía como diálogo horizontal y político de la palabra en un contexto marcado por la tecnología y la necesidad de repensar la democracia y la ciudadanía.
