Published: September 2023

Рассмотрена современная безопасная технология производства низкоконцентрированного гипохлорита натрия из растворов поваренной соли. Подробно описаны основные стадии технологического процесса. Особое внимание уделено вопросам промышленной безопасности и надежной эксплуатации электролизеров – установок приготовления гипохлорита натрия, произведенного на Южной и Северной водопроводных станциях ГУП «Водоканал Санкт-Петербурга». Использование низкоконцентрированных растворов гипохлорита натрия позволяет повысить безопасность технологических процессов очистки воды. Сырьем для производства гипохлорита натрия служит поваренная соль. Поскольку реагент используется непосредственно на месте получения, отпадает необходимость транспортировки. Сочетание обеззараживания обрабатываемой воды низкоконцентрированным гипохлоритом натрия (первая ступень) с ультрафиолетовым облучением (вторая ступень) перед подачей в городскую водопроводную сеть гарантирует полное соответствие качества воды по микробиологическим показателям действующим нормативам и ее высокую эпидемиологическую безопасность.
An advanced safe technology for the production of low-concentration sodium hypochlorite from salt brine is considered. The main stages of the technological process are described in detail. Particular attention is paid to the issues of industrial safety and reliable operation of electrolyzers – units for the preparation of sodium hypochlorite at the Southern and Northern water treatment facilities of SUE «Vodokanal of St. Petersburg». The use of low-concentration solutions of sodium hypochlorite provides for improving the safety of water purification processes. Salt is the raw material for the production of sodium hypochlorite. Since the chemical is used directly at the place of production, there is no need for transportation. The combination of disinfection of treated water with low-concentration sodium hypochlorite (first stage) with ultraviolet irradiation (second stage) before supplying it to the city water supply network guarantees full compliance of water quality in terms of microbiological indicators with current standards and its high epidemiological safety.

Published: September 2023

<p>Artificial Intelligence has gained widespread adoption across different industrial sectors, serving as a versatile tool to carry out a diverse array of tasks, ranging from image classification and traffic forecasting to natural language processing and speech recognition. In the space domain, however, a special focus must be placed on area overhead, power consumption, and fault-tolerant solutions. In this particular scenario, soft GeneralPurpose Computing on Graphic Processing Units has the potential to revolutionise space-related activities. Indeed, by leveraging both Field Programmable Gate Array technology and Graphic Processing Unit computing, it becomes feasible to achieve highperformance capabilities without compromising neither power consumption nor radiation tolerance features. Moreover, the use of reconfigurable hardware can facilitate the acceleration of a wide range of Machine Learning algorithms, avoiding the drawbacks of excessive specialisation. This paper explores the State-of-the-Art in terms of hardware platforms for on-the-edge acceleration of Artificial Intelligence algorithms and compares it with a possible System-on-Chip implementation based on a softGraphic Processing Unit. Then, the attention is shifted towards the investigation of key aspects for future space missions, such as reliability and Dynamic Partial Reconfiguration. We point out the lack of European technological solutions, emphasising the promising potential offered by NanoXplore devices. We also discuss the importance of fault detection and mitigation techniques in space applications, covering the most commonly employed hardware methods for reliability enhancement and highlighting the lack of work in the field of General-Purpose Computing for Graphic Processing Units, especially in the space sector. Furthermore, we briefly examine the implementation of Dynamic Partial Reconfiguration over a System-on-Chip featuring a softGraphic Processing Unit IP. Finally, in the last section of the paper, we hint at future development of the project and conclude the work. </p>

Published: September 2023

<p>This work develops a novel observer-based finite-time methodology to make disturbed wheeled mobile robots (WMRs) follow a desired reference signal. With the kinematic and reference models, two decoupled systems are computed. Then, each subsystem’s control signal is split into three terms. The first part estimates the disturbances affecting the system, transforming the closed-loop system into two new second-order systems with uniformly bounded and convergent disturbance terms. Then, based on a new sliding surface and a design function, the second and third controller’s parts are employed to accomplish the trajectory tracking task despite disturbances. The proposed controller is compared against a finite-time and a feedback controller. Then, detailed numerical simulations show the outstanding performance of the novel proposal.</p>

Development of normalized acoustic response analysis for soil-structure contact state evaluation
Authors: Churkin Aleksei , Smirnov Igor 
Published: September 2023

Abstract: Introduction. Impulse response testing is currently one of the most common methods of acoustic express diagnostics of the foundation slabs and other plate-like structures state, but is relatively uncommon in the Russian Federation. A modification of this technique, based on the analysis of normalized response parameters, is being actively developed by Russian specialists to assess the quality of soil-structure contact. The issue of developing of the new informative parameters and criteria for identifying of anomalies associated with contact violations is topical.
Aim. The purpose of the work is to inform specialists about the capabilities of the normalized acoustic response analysis method for localizing zones of soil-structure contact violation. It is proposed to apply the attribute "void index" and an auxiliary criterion for data analysis based on the nature of the distribution of attribute values.
Materials and methods. The features of the normalized acoustic response testing metodologia for soil-structure contact violations searching are described. The method for calculating the attribute "void index" for the data of the technique is shown. A criterion for the selection of anomalous areas is proposed, based on the data analysis of the nature of the distribution of attribute values.
Results. Verification of the "void index" attribute application for searching for zones of soil-structural contact violation is shown on the results of a survey of a tunnel liner physical model with a known position of the void. An example of the results of a survey of a slab at the base of an underground car park shows the use of a "void index" in conjunction with the normalized signal energy attribute. A method for statistical processing of the results is proposed, which supplements the traditionally used "three sigma" criterion.
Conclusions. A method of the "void index" attribute application to localize zones of soil-structure contact violation for the normalized acoustic response analysis method is shown. A method for statistical data processing is proposed, considering the nature of the distribution of response attributes.

Published: September 2023

The current state of practice of seismic risk mitigation policy in the following countries is analyzed: Japan, USA, China, Italy and the Russian Federation. In particular, the paper compares seismic retrofit policies for existing buildings and financing mechanisms for comprehensive seismic risk mitigation in the context of each country's regulatory framework. The analysis of the current seismic risk mitigation policy in the Russian Federation leads to the conclusion that it needs serious modernization and reorganization, including: 1) development of a new generation of standards specifying nonlinear analysis methods and 2) development of effective financing mechanisms for the seismic evaluation and seismic modernization of the existing building stock.
The aim of this paper is to identify best practices in seismic retrofitting policy that may be useful for the implementation and adjustment of seismic risk mitigation policies in the Russian Federation at the federal and regional levels.
The result of the paper is a set of recommendations based on the most effective seismic risk mitigation policy instruments, grouped according to the key stages of the seismic amplification process:
–	risk assessment of existing buildings;
–	knowledge transfer;
–	setting targets for the seismic modernization;
–	implementation of the seismic strengthening policy;
–	policy implementation monitoring.
The Temporal Symmetrical and Translational Structure in Gamma-Ray Burst Light Curves
Authors: Liu Dong-Jie , Zou Yuan-Chuan 
Published: September 2023

Abstract
Tremendous information is hidden in the light curve of a gamma-ray burst (GRB). Based on Compton Gamma Ray Observatory/Burst And Transient Source Experiment (BATSE) data, Hakkila found a majority of GRBs can be characterized by a smooth, single-peaked component superposed with a temporally symmetrical residual structure, i.e., a mirror feature for the fast-varying component. In this study, we conduct a similar analysis on the same data, as well as on Fermi/Gamma-Ray Burst Monitor data. We obtained a similar conclusion, which is that most GRBs have this symmetrical fast-varying component. Furthermore, we chose an alternative model to characterize the smooth component and used a three-parameter model to identify the residual, i.e., the fast component. By choosing 226 BATSE GRBs based on a few criteria, we checked the time-symmetrical feature and time-translational feature for the fast components and found the ratio is roughly 1:1. We propose that both features could come from the structure of the ejected shells. In the future, the Square Kilometre Array might be able to observe the early radio emission from the collision of the shells.
L’évaluation des compétences, facteur de performance ? Quels enjeux pour le cadre de santé ?
Authors: Neu-Stein Sophie 
Published: September 2023

L’hôpital est une organisation complexe en pleine mutation (innovation, digitalisation, renouvellement des méthodes de travail et de management) relevant désormais d’un « continuum » d’adaptations et d’imprévus. La gestion des compétences (les savoirs, les savoir-faire, les règles et comportements professionnels, les valeurs…) est ainsi devenue un élément clé dans la recherche de la performance. Dans un contexte de recherche permanente de la performance, la fonction du cadre, au centre de toutes les tensions, passe ainsi de la surveillance à celle de gestion avec le souci permanent d’optimisation en proposant des processus de structuration, de création de sens dans la gestion des actions à mener pour établir ou rétablir une stabilité et un équilibre pour l’équipe qu’il dirige. Au cœur de ce domaine de réflexion, il a paru opportun de s’intéresser à la thématique de l’évaluation considérée comme une activité banale, liée à des processus d’apprentissage et de formation. Cette pratique de l’évaluation, certes légitime et nécessaire, se doit toutefois d’être en phase avec les défis de l’époque et soumet nécessairement l’hôpital à l’épreuve d’un nouveau management caractérisé par le développement de l’efficience, l’engagement et l’adaptabilité des acteurs. La démarche évaluation liée au management des compétences a pour particularité de projeter — individuellement et collectivement — les acteurs dans l’avenir. La situation sans précédent générée par la Covid-19 a renforcé et amplifié cette réflexion. La gestion des ressources humaines est ainsi au cœur des interrogations, rivière du soin caractérisé par l’existence d’un nouvel environnement dicté notamment par le progrès des technologies, les attentes grandissantes des patients et un nouveau rapport au travail : les malades changent, leurs attentes sont grandissantes ; le rapport au travail change, et enfin le progrès médical s’accélère : de nouvelles charges pour le management. Par ailleurs, les enjeux hospitaliers s’inspirent de plus en plus, et non seulement dans le vocabulaire, des modèles de performance managériale et d’innovation technologique issues du monde de l’entreprise pour les intégrer dans les processus de production de soins. Les nouvelles méthodes de management sont aujourd’hui omniprésentes dans les discours qui entourent l’hôpital. Les injonctions à la performance sont centrales et encouragent le développement de nouveaux modes de management : développement de la polyvalence et de « l’apprenance », management « agile ». Dans cet article, réalisé à partir d’un mémoire, nous sommes amenés à répondre à la question suivante : en quoi l’évaluation des compétences de l’équipe contribue-t-elle à améliorer la performance ?
De l’identification à la fidélisation organisationnelle : quels rôles pour le manager de proximité ?
Authors: Lagarde Fabienne 
Published: September 2023

Dans le contexte de la crise sanitaire Covid, le besoin massif en personnel soignant dans les établissements de santé a mis en avant les difficultés de recrutement et de fidélisation organisationnelle. Cet article présente les résultats d’une étude qualitative exploratoire menée auprès de techniciens de laboratoire, ainsi que le rôle joué par le manager de proximité lors de la mise en place d’une plateforme de dépistage de masse du coronavirus SARS-CoV-2. Les analyses de documents et du contenu de dix-huit entretiens semi-directifs ont permis d’établir le lien entre une identification organisationnelle forte et l’investissement au sein de l’organisation incarné par le souhait de rester, soit : la fidélisation organisationnelle. Ces deux concepts inter reliés sont profondément assujettis à la notion de sens au travail. En effet, au regard de ces résultats empiriques, le Sensegiving et le Sensemaking semblent caractériser les différents rôles tenus par le manager de proximité.

Authors: Baca-Moreno Jazmin , Henaine-Berra Andrée , Osorio-Landa Hillary Kimberly , Berrones-Medina David , García-Aguirre Gerardo 
Published: September 2023

Background and Objective:
Dome-shaped macula (DSM) and tilted disc syndrome (TDS) are two macular abnormalities that may occur in eyes with high myopia. The aim of this study was to determine the prevalence of both entities in our population.

Patients and Methods:
This was a prospective and observational study. Optical coherence tomography of the macula was performed in eyes with high myopia (spherical equivalent [SE] of −8D or greater) to assess the prevalence of DSM and TDS.

Results:

Sixty-eight eyes were included. Three eyes (4.41%) had DSM and 8 (11.76%) eyes had TDS. The most common macular anomaly was posterior staphyloma (PS) (12 [17.65%]). From the eyes with DSM (
n
= 3), only two presented PS. An older age and a higher SE were predisposing factors for PS (
P
= 0.003).

Conclusions:
A lower prevalence of DSM and a higher prevalence of TDS was observed in our population compared to those reported in literature.

Evaluation of Inflammation in the Peripheral Multiple Sclerosis Retina Using Ultra-Widefield Optical Coherence Tomography: A Pilot Study
Authors: O'Riordan Matthew M. , Cahill Mark T. , Campbell Matthew , Kearney Hugh 
Published: September 2023

Background and Objective:
Reports of fundus fluorescein angiography (FFA) in active multiple sclerosis (MS) have shown peripheral perivenous sheathing. We sought to assess the feasibility of ultra-widefield (UWF) FFA and optical coherence tomography (OCT) in assessing the peripheral retina in MS.

Materials and Methods:
Participants with MS and healthy controls underwent bilateral UWF fundus photography and FFA. Swept-source OCTs were captured centrally, peripherally, and to delineate any abnormalities visualized.

Results:
We recruited five people with relapsing remitting MS, with a mean age of 36.9 (± 9.9), mean disease duration of 11 years (± 6.3), and a median expanded disability status score of 0.75 (0 to 2.5). In all MS participants, the disease was not active clinically or radiologically. Using UWF-FFA and OCT, we did not detect clear evidence of peripheral retinal abnormalities, which is consistent with the participants having inactive MS.

Conclusion:
A pilot study using UWF-FFA and peripheral OCT to examine the retina in MS suggests that it may be useful to perform a larger prospective longitudinal study to establish its potential as a monitor of disease activity.

Comparative evaluation of surface microhardness of bleached enamel subjected to erosion after using Remin Pro and NovaMin: An in vitro study
Authors: Hugar Saraswati , Basavanna RS , Dhanyakumar NM 
Published: September 2023

Aim and Objective:
The aim of the study was to evaluate and compare the surface microhardness of bleached enamel subjected to erosion after using Remin Pro and NovaMin.

Methodology:
Thirty human maxillary premolars were selected and decoronated. Enamel blocks were obtained from these teeth and subjected to three phases of treatment: bleaching phase, remineralizing phase, and erosive phase. Samples were divided into four groups with 15 samples each. Group I: subjected to erosion without application of bleaching and remineralizing agent, Group II: treatment with 35% carbamide peroxide without application of remineralizing agent, Group III: treatment with 35% carbamide peroxide, followed by application of Remin Pro, and Group IV: treatment with 35% carbamide peroxide followed by application of NovaMin. Initial and final surface microhardness was analyzed using Vickers microhardness.

Results:
There was a statistically significant difference between control and experimental groups. The percentage of surface hardness loss (%SHL) value was significantly higher in Group II in comparison with the other groups of treatment. However, Group IV and Group III showed the lowest %SHL compared to GI.

Conclusion:
Within the limitations of this present in vitro study, NovaMin has better-remineralizing potential than Remin Pro and demonstrated increased microhardness of bleached enamel.

Published: September 2023

BACKGROUND AND OBJECTIVES:
Treatment of HIV–tuberculosis (TB) coinfected patients requires antitubercular and antiretroviral drugs to be administered concomitantly; challenges include pill burden, patient compliance, drug interactions, etc. The present study is planned to assess and compare the rate of adherence to TB medicines and antiretroviral therapy (ART) in patients with HIV–TB coinfection.

MATERIALS AND METHODS:
A cross-sectional questionnaire-based study was carried out in the ART clinic of a tertiary care teaching hospital in 146 patients of acquired immunodeficiency syndrome coinfected with TB. Adherence to therapy was assessed using the Morisky eight-item medication adherence questionnaire.

RESULTS:
One hundred and forty-six patients participated in the study, of which 102 participants forgot to take the TB medication and 82 of the participants forgot to take ART sometimes. Furthermore, 78 participants did not take TB medicine, while 57 did not take ART in the past 2 weeks for reasons other than forgetfulness. These results were statistically significant. The sociodemographic factor significantly associated with low adherence to ART was addiction. In the Morisky eight-item medication adherence to TB drugs, 0.68% of patients showed high adherence, 17.8% of patients showed medium adherence, and 81.5% showed low adherence, whereas for ARV medicines, 0.68% of patients showed high adherence, 18.49% of patients showed medium adherence, and 80.82% showed low adherence.

CONCLUSION:
Adherence level obtained in this study was relatively low for both ARV and TB treatment. Patient’s affordability and forgetfulness are the major causes of nonadherence. Similarly, addiction is also one of the important causes of nonadherence to ARV treatment in our study.
