Выявлено отсутствие связи физического износа с предельно допустимыми характеристиками надежности и безопасности. Выводы. На основании выявленных несоответствий обоснована необходимость создания методики определения физического износа во взаимосвязи с остаточным ресурсом здания и его показателями надежности.
Statement of the problem. In the modern construction industry, rules have emerged for determining the need for repair work on buildings and structures by calculating the amount of physical deterioration and tear of both individual structures and the structure as a whole. During expert practice, significant shortcomings of the existing methodology for determining physical deterioration were identified, affecting the accuracy and objectivity of the results. Results. In this article, the authors analyzed regulatory documentation containing the concepts of physical deterioration and tear and methods for determining it, the shortcomings of the current methodology, as well as an analysis of the relationship between physical deterioration and tear and the purpose of repairs. As a result of the analysis, it was established that in various regulatory documents the concepts of physical deterioration and tear have differences, and the essence of the methods for determining it also varies. It was revealed that there is no connection between physical deterioration and tear and the maximum permissible characteristics of reliability and safety. Conclusions. In the conclusions of this article, based on the identified inconsistencies, the need to create a methodology for determining physical deterioration and tear in relation to the residual life of the building and its reliability indicators is substantiated.

Постановка задачи. Цель работы заключается в разработке усовершенствованной методики статического анализа несущего каркаса комбинированного покрытия шпренгельного типа, предназначенной для применения при назначении основных параметров конструктивного решения на этапе вариантного проектирования. Результаты. Предложены унифицированные зависимости для определения усилий и изгибающих моментов в элементах конструкции. Данные зависимости выражены через параметры, позволяющие вести расчет на действие внешней полезной или единичной нагрузки, а также на предварительное напряжение. Предложена методика пошагового выключения сжатых связей из расчетной схемы конструкции. Выводы. Исследуемая конструкция, включающая элементы, обладающие пониженной жесткостью, не проявляет значимого геометрически нелинейного поведения на стадии эксплуатации, а ее статический анализ допустимо выполнять методом сил. Результаты работы могут быть использованы при поиске оптимальных проектных решений и для численного исследования работы комбинированных конструкций с выявлением закономерностей их напряженно-деформированного состояния.
Statement of the problem. The purpose is to develop an improved technique for the static analysis of the load-bearing framework of the hybrid strutted roof structure. The technique is to facilitate the main structural parameters determination at the preliminary design stage. Results. Unified expressions for determining the forces and the bending moments in the structural elements are proposed. The expressions are written in terms of the parameters which allow switching between operational and unit loads, as well as, the pre-stress only, when performing the analysis of the structure. A step-by-step technique for eliminating compressed ties from the design diagram is proposed. Conclusions. In spite of low-stiffness members included, the structure under investigation does not exhibit significant geometrically nonlinear behavior at the operational stage. Thus, the flexibility method of the linear structural mechanics is valid for its static analysis. The results of the work can be used for optimal design solutions determination, as well as, for the numerical research of the hybrid structures in order to clarify their stress-strain behavior.

Published: September 2024

Постановка задачи. Один из наименее изученных архитектурных ансамблей Воронежа дореволюционного периода — комплекс лечебных зданий Приказа общественного призрения, являющийся в настоящее время объектом культурного наследия регионального значения. В архитектурном краеведении Воронежа отсутствует полноценно собранная и проанализированная специалистом в области истории архитектуры информация, которая позволила бы проследить весь процесс создания одного из крупнейших исторически сложившихся городских ансамблей Воронежа и объективно оценить роль местных зодчих в его создании. Результаты. Изучена история проектирования и строительства комплекса лечебных зданий Приказа общественного призрения и проведен сравнительный анализ местной проектной практики с общероссийской этого же периода. Выводы. Сделан вывод, что развитие и трансформация состава зданий больничного комплекса происходили на протяжении всего периода его существования. История выбора места и проектирования зданий Приказа общественного призрения, с одной стороны, весьма показательна для организации строительства казенных зданий в России в первой половине XIX в. и в то же время уникальна, поскольку она значительно опережала общероссийскую практику при создании подобного рода объектов.
Statement of the problem. One of the least studied architectural ensembles of Voronezh of the pre-revolutionary period is the complex of medical buildings of the Public Charity Office, which is currently an object of cultural heritage of regional significance. In the architectural local history of Voronezh, there is no information fully collected and analyzed by a specialist in the field of architectural history, which would allow us to trace the entire process of creating one of the largest historically established urban ensembles and objectively assess the role of local architects in its creation. Results. The history of the design and construction of a complex of medical buildings under the Public Charity Office has been studied and a comparative analysis of local design practice with the all-Russian practice of the same period has been carried out. Conclusions. It is concluded that the development and transformation of the composition of the buildings of the hospital complex occurred throughout the entire period of its existence. The history of choosing the location and design of buildings for the Public Charity Office is very indicative of the organization of the construction of government buildings in Russia in the first half of the 19th century.
Effect of Standards on Sub-Saharan African Countries’Agricultural Exports
Authors: Dontsi Dontsi , Nankap Seujib Alexis 
Published: September 2024

The aim of this paper is to investigate the impact of public standards (SPS, TBT) on Sub-Saharan Africa’s exports of food, which represent less than 3% of world food exports. This situation is accentuated by the standards on agricultural goods. A modest contribution has been made both theoretically and empirically. Theoretically, the basic model has been criticized and subsequently reformulated by incorporating the cost function of food production in the exporting country. This reformulation made it possible to build a model, the methodology of which was developed by several authors. Empirical analysis shows that SPS and TBT standards have a negative impact on agricultural exports of the Sub-Saharan African (SSA) countries.

Published: September 2024

In this study, we conducted a density functional theory investigation of the structural, electronic, magnetic, and optical properties of manganese-doped lead-free ferroelectric Ba(Zr0.2Ti0.8)O3 (BZT) materials. The electronic structure calculations revealed that pristine BZT material behaves as a p-type semiconductor with direct and indirect bandgaps of 3.18 eV and 2.08 eV, respectively. Upon Mn doping, the bandgap values converge to zero, indicating a transition from semiconductor to metal behavior. Additionally, the asymmetrical spin-polarized density of states and significant magnetic moments, determined through Mulliken population analysis, suggest the induction of magnetism in the BZT material due to Mn doping. Magnetic moments of 0.98 µB/f.u., 0.57 µB/f.u., and 0.87 µB/f.u. were observed when Mn substitutes into Ba, Ti, and interstitial sites, respectively. Furthermore, we observed substantial enhancements in dielectric constants and changes in other properties such as refractive index, loss function, and reflectivity upon Mn doping, suggesting alterations in the optoelectronic properties of the materials. Our findings contribute to the understanding of transition metal-doped lead-free ferroelectric BZT materials and provide more information for the development of future smart electronic and optoelectronic devices.

Unique Branding of Deaf Coffee: Opening a New Window to Introduce Deaf Friends Culture and BISINDO Sign Language
Authors: Yulia Irla , Dogboyou Diana 
Published: September 2024

Kopi Tuli represents a pioneering initiative in Indonesian coffee shop management, being one of the first establishments to be fully managed by Teman Tuli. In terms of communication, Teman Tuli utilises Indonesian Sign Language (BISINDO) as the primary language. This research project aims to analyse the branding strategy adopted by Kopi Tuli to increase awareness of Teman Tuli's existence and to evaluate the impact of Kopi Tuli's branding in introducing BISINDO sign language. The research was conducted using qualitative methods, comprising a literature review, observation and in-depth interviews. The results demonstrate that the branding strategy employed by Kopi Tuli is efficacious in increasing public awareness of Teman Tuli's existence and the introduction of BISINDO sign language. The branding strategy that has been deemed effective encompasses several pivotal elements that have collectively succeeded in attracting public attention. These include a transparent and distinctive brand positioning, a robust brand identity, the utilisation of social media as a pivotal campaign medium, an educational customer experience that enables direct acquisition of sign language skills, and an amplified public awareness of the Teman Tuli community.
Flow-based Generative Emulation of Grids of Stellar Evolutionary Models
Authors: Hon Marc , Li Yaguang , Ong Joel 
Published: September 2024

Abstract
We present a flow-based generative approach to emulate grids of stellar evolutionary models. By interpreting the input parameters and output properties of these models as multidimensional probability distributions, we train conditional normalizing flows to learn and predict the complex relationships between grid inputs and outputs in the form of conditional joint distributions. Leveraging the expressive power and versatility of these flows, we showcase their ability to emulate a variety of evolutionary tracks and isochrones across a continuous range of input parameters. In addition, we describe a simple Bayesian approach for estimating stellar parameters using these flows and demonstrate its application to asteroseismic data sets of red giants observed by the Kepler mission. By applying this approach to red giants in open clusters NGC 6791 and NGC 6819, we illustrate how large age uncertainties can arise when fitting only to global asteroseismic and spectroscopic parameters without prior information on initial helium abundances and mixing length parameter values. We also conduct inference using the flow at a large scale by determining revised estimates of masses and radii for 15,388 field red giants. These estimates show improved agreement with results from existing grid-based modeling, reveal distinct population-level features in the red clump, and suggest that the masses of Kepler red giants previously determined using the corrected asteroseismic scaling relations have been overestimated by 5%–10%.

Abstract
The dispersion measure of fast radio bursts (FRBs), arising from the interactions with free electrons along the propagation path, constitutes a unique probe of the cosmic baryon distribution. Their constraining power is further enhanced in combination with observations of the foreground large-scale structure and intervening galaxies. In this work, we present the first constraints on the partition of the cosmic baryons between the intergalactic medium (IGM) and circumgalactic medium (CGM), inferred from the FLIMFLAM spectroscopic survey. In its first data release, the FLIMFLAM survey targeted galaxies in the foreground of eight localized FRBs. Using Bayesian techniques, we reconstruct the underlying ∼Mpc-scale matter density field that is traced by the IGM gas. Simultaneously, deeper spectroscopy of intervening foreground galaxies (at impact parameters b

Dissipation of AGN Jets in a Clumpy Interstellar Medium

Published: September 2024

Abstract
Accreting supermassive black holes frequently power jets that interact with the interstellar medium (ISM)/circumgalactic medium, regulating star formation in the galaxy. Highly supersonic jets launched by active galactic nuclei (AGN) power a cocoon that confines them and shocks the ambient medium. We build on the models of narrow conical jets interacting with a smooth ambient medium, including the effect of dense clouds, which are an essential ingredient of a multiphase ISM. The key physical ingredient of this model is that the clouds along the supersonic jet beam strongly decelerate the jet head but the subsonic cocoon easily moves around the clouds without much resistance. We propose scalings for important physical quantities—cocoon pressure, head and cocoon speed, and jet radius. For the first time, we obtain the analytic condition on the ambient medium’s clumpiness for the jet to dissipate within the cocoon and verify it with numerical simulations of conical jets interacting with a uniform ISM with embedded spherical clouds. A jet is defined to be dissipated when the cocoon speed exceeds the speed of the jet head. We compare our models with more sophisticated numerical simulations and direct observations of jet–ISM interaction (e.g., quasar J1316+1753), and we discuss implications for the Fermi/eROSITA bubbles. Our work also motivates effective subgrid models for AGN jet feedback in a clumpy ISM unresolved by the present generation of cosmological galaxy formation simulations.
Spindown of Pulsars Interacting with Companion Winds: The Impact of Magnetospheric Compression
Authors: Zhong Yici , Spitkovsky Anatoly , Mahlmann Jens F. , Hakobyan Hayk 
Published: September 2024

Abstract
Pulsars in binary systems with strong companion winds can have the magnetopause separating their magnetosphere from the wind located well within their light cylinder. This bow-like enclosure effectively creates a waveguide that confines the pulsar’s electromagnetic fields and can significantly alter its spindown. In this paper, we study the spindown of compressed pulsar magnetospheres in such systems. We parameterize the confinement as the ratio between the equatorial position of the magnetopause (or standoff distance) R
m and the pulsar’s light cylinder R
LC. Using particle-in-cell simulations, we quantify the pulsar spindown for a range of compressions, R
m/R
LC = 1/3–1, and inclination angles, χ = 0°…90°, between magnetic and rotation axes. Our strongly confined models (R
m/R
LC = 1/3) show two distinct limits. For χ = 0°, the spindown of a compressed pulsar magnetosphere is enhanced by approximately a factor of three compared to an isolated pulsar due to the increased number of open magnetic field lines. Conversely, for χ = 90°, the compressed pulsar spins down at less than 40% of the rate of an isolated reference pulsar due to the mismatch between the pulsar wind stripe wavelength and the waveguide size. We apply our analysis to the 2.77 s oblique rotator (χ = 60°) in the double-pulsar system PSR J0737-3039. With the numerically derived spindown estimate, we constrain its surface magnetic field to B
* ≈ (7.3 ± 0.2) × 1011 G. We discuss the time modulation of its period derivative, the effects of compression on its braking index, and implications for the radio eclipse in PSR J0737-3039.
