Authors: Sousa Samuel M , Morais Helane L O , Santos Joyce C C , Barboza Ana Paula M , Neves Bernardo R A , Pinto Elisângela S , Prado Mariana C
Published: January 2023

Industrial applications of nanomaterials require large-scale production methods, such as liquid phase exfoliation (LPE). Regarding this, it is imperative to characterize the obtained materials to tailor parameters such as exfoliation medium, duration, and mechanical energy source to the desired applications. This work presents results of statistical analyses of talc flakes obtained by LPE in four different media. Talc is a phyllosilicate that can be exfoliated into nanoflakes with great mechanical properties. Sodium cholate at two different concentrations (below and at the critical micelar concentration), butanone, and Triton-X100 were employed as exfoliation medium for talc. Using recent published statistical analysis methods based on atomic force microscopy images of thousands of flakes, the shape and size distribution of nanotalc obtained using the four different media are compared. This comparison highlights the strengths and weaknesses of the media tested and hopefully will facilitate the choice of the medium for applications that have specific requirements.

The Blasius flow over a movable and permeable plate is envisaged in this study. Water-based hybrid nanofluid is incorporated with the insertion of thermal radiation, suction, and a convectively heated plate. The governing partial differential equations that simulate the fluid model are modified to ordinary differential equations through the implementation of self-similar transformation. A numerical solver known as bvp4c in Matlab is adopted to solve the problem numerically through the finite difference code with the Lobatto IIIa formula. Non-unique solutions are acquirable when the plate and the flow move in a dissimilar direction. As conducting the stability analysis, it is validated that the first solution is stable and reliable. The findings reveal that the imposition of stronger thermal radiation and greater Biot number for convection can lead to a better heat transfer performance. The 2% volume fraction of copper in the 1% volume fraction of alumina nanofluid composition would lead to greater skin friction when the plate is moving oppositely from the flow direction compared to the lesser volume fraction of copper. The boundary layer separation also can be efficiently prevented by composing a 2% copper volume fraction in the 1% alumina-water nanofluid compared to the lesser copper volume fraction.

Published: January 2023

In this present work, the effects of coating of graphene oxide (GO) at different concentrations (0, 0.2, 0.3, 0.4, 0.5, and 0.6 mg/ml) onto zinc oxide (ZnO) nanostructured were investigated. ZnO and ZnO coated with GO (ZnO/GO) were prepared using immersion method. The structural, morphology and optical properties of all samples have been studied using x-ray diffraction (XRD), field emission scanning microscopy (FESEM) and UV Vis spectroscopy. The peak obtained from the XRD pattern shows that all samples are in the hexagonal-wurtzite structure. The (002) peak shows the strongest intensity for all samples with the highest (002) peak obtained for the ZnO/GO sample coated at a GO concentration of 0.5 mg/ml. The diameter of ZnO/GO nanostructured samples decreased after coating with GO at concentrations of 0.2 to 0.5 mg/ml and the diameter increased again when ZnO nanostructures were coated with GO at above 0.5 mg/ml. The highest transmission spectrum was obtained for the ZnO/GO sample coated with GO at a concentration of 0.5 mg/ml. In conclusion, the effect of GO coating on ZnO nanostructured can be changed at different concentrations of GO. The optimal properties of ZnO/GO may be suitable as a photoanode in DSSC applications.

Published: January 2023

Computational Fluid Dynamics analysis was used to study the effect of expansion level in a suddenly expanded flow for a converging-diverging nozzle expanded to the duct of larger diameter at supersonic Mach number. Parameters include the nozzle pressure ratio (NPR), L/D ratio, and area ratio. The model of the converging-diverging (C-D) nozzle suddenly expanding into the enlarged duct with the cavity was created using the Design Modeler of ANSYS Fluent. The Mach number of the study is 1.6. The area ratio varied from 2.25 to 5.29, and the L/D ranged from 1 to 10. The simulated nozzle pressure ratio (NPR) ranged from 2, 3, 4.25, and 6.375. The outcome demonstrated that the geometric alteration and NPR strongly affect the base pressure. The ambient pressure influences result in lower L/Ds. The cavity of aspect ratio 1 is most effective in raising the base pressure. Increasing the width does not yield any desirable results. However, the location of the cavity played a very significant role in base pressure regulation. The duct's wall pressure and the flow field remained identical with and without control.

This is the first publication in a series of the three papers that present the research findings of the diagnostic project on the quality of Bachelors’ final papers initiated by the Faculty of Economics Pedagogical committee in 2021. We present the findings of academic quality analysis and the typology of the main formats of Bachelors’ final papers. The research is based on a methodology that is specially developed along the lines of positive economics approach. Its application allows us to demonstrate the qualitative features of the body of final papers prepared by our graduates which include inter alia quality of literature review, research statement, tools of analysis and interpretation of findings. We offer the steps for further strengthening the analytical quality of final papers, including early submission of research hypothesis, elective courses on the methods of academic research and research seminars for undergraduates. We also present a typology of formats for final papers covering Economics and Management streams of study. Based on our positive analysis, we have identified six primary formats of Bachelors’ final papers, which can be combined into three more general categories: academic, project and research, and applied project formats. A comparative analysis of formats in economics and management papers confirms the applicability of common criteria for evaluating and grading the papers, alongside common guidelines for final paper preparation. The study proves the viability of diverse analytical methods while preparing final papers in both streams of study.

The article presents an overview of the main available methodological approaches to implement the procedure of a quantitative assessment of workforce’s occupational risk in companies. The research methodology is based on the analysis of recent scientific publications and the investigation of methods and tools used in occupational risk assessment. In this study, the authors identify the advantages and disadvantages of using each methodology considered, assess the feasibility of the methods applied in activities aimed at improving the working conditions, industrial traumatism and occupational diseases reduction. The study proves that existing techniques based on rating-interval evaluating systems and matrix methods have significant limitations including infeasibility of application for the development of the list of activities to reduce occupational risk and a low level of evidence of the indicators and the assessment criteria applied. The analysis concludes with the requirements for the methodological approach to a quantitative occupational risk assessment
Portrait of a creative worker: a sociological approach
Authors: Volkov S. K. , Efimov E. G.
Published: January 2023

The article attempts to highlight the socio-psychological portrait of a Russian worker in creative sphere. The relevance of the research is determined by the contradiction between the desire to develop the creative class and the lack of a clear understanding of the essence of this social group. The methodological basis of the research includes both classic works by R. Florida and modern scientific publications on the study of the creative class by Russian and foreign authors. The analysis of theoretical studies shows the impossibility to establish a clear professional affiliation due to both terminological uncertainty and the rapid digitalization of society during the pandemic years, which led to a change in the position of the creative class and actualized the need to study it. The empirical basis is formed by the data from the online questionnaire survey carried out among the participants of the project of the Agency of Strategic Initiatives (rurban.space) to search and unite representatives of the creative class within the framework of the development of urban space models. The article attempts to outline the peculiarities of the formation of the Russian creative class. The results allow us to describe the portrait of a creative worker as a member of a social group that exists within the framework of traditional socio-economic institutions. The respondents self-identify themselves as representatives of the lower and middle classes, gravitating towards full-time employment within urban agglomerations. When selecting the professional qualities inherent in a creative worker, respondents gave preference to «creativity» and «communicativeness,» completely excluding «tolerance,» which is considered mandatory in Western culture. The data obtained in this study allowed us to rethink the established stereotypes and simplifying heuristics about the nature of creative work and the socioeconomic portrait of a creative worker.

Published: January 2023

The article presents the methodology of integral assessment of Russian regions economic development. Currently, there is a significant number of methods to assess the state of country’s economy and individual regions, including Russia. However, they are often poorly formalized or difficult to implement. The authors offer the methodology to assess the economic development of Russia’s regions using the integral index which minimizes the number of the indicators used. The study applies objective indicators of official statistics which most fully and reliably reflect the essence of regional economic development in Russia such as: gross regional product, the cost of fixed assets adjusted for their depreciation, investments in fixed assets — all of them per capita. The methodology makes it possible to provide an annual assessment of Russian regions economic development to determine the specifics of regional policy.

Published: January 2023

Generalization of the structure of financing of the main managers of federal budget funds in the context of sections and subsections of expenditures of the budget classification in order to identify the features and problems of further structuring costs in the context of the development of digitalization of budget processes. The current system of structuring sections and subsections of the budget classification of expenditures is considered, the quantitative composition of the codes of sections, subsections and expenditures of the GRBS of the federal budget for 2020 is analyzed. The ratio of the number of codes of sections and subsections of the budget classification of federal budget expenditures for the GRBS for 2020 and the regularity of their relationship is investigated. A low correlation between the number of codes of sections (subsections) and the volume of budget expenditures at the federal level for financing the GRBS was quantitatively revealed. A new concept is proposed — the consumption capacity of the code. The average expenditure intensity of one code of the budget expenditure section for the GRBS is estimated, and the structure of the ratio of budget expenditures and the expenditure intensity of the GRBS cost section code is studied according to the results of the federal budget execution for 2020. The provisions of the organization of the approach to building a digital budget are proposed. The conclusions of the generalization are reduced to a positive assessment in general of the possibilities of analyzing budget expenditures in the current classification of budget expenditures and the need for further deepening of digitalization, contributing to a more rational study and analysis of the effectiveness of the use of budget expenditures of the country.
Corporate financial responsibility and company financial performance: evidence from Russia
Authors: Makarov A. S. , Ryabova E. V. , Feduleeva D. D.
Published: January 2023

The paper analyses two alternative theoretical interpretations the nature of Corporate Environmental Responsibility (CER)-Financial Performance (FP) interconnections based on the concept, that the implementation of CER measures increases the company financial efficiency, or the alternative theory the CER strategy development can only be applicable for stable companies with sufficient financial resources. The recent empirical literature shows many inconsistencies in each of the theoretical explanations the effective environmental and company financial policy formation. There are no Russian and foreign studies explaining the environmental responsibility and financial efficiency interconnection for Russian companies. It determines the purpose of this research and the novelty of the obtained research results. We use the least squares method in order to argue that financial efficiency is a significant driver for environmental responsibility of Russian companies. We also argue that the influence of financial efficiency on environmental responsibility varies according to the ownership structure and the foreign and state participation in the company.

In conclusion, the author presents the key areas of stimulating digitalization of import substitution in Russia under sanctions.
The entrepreneurial networks as an object of empirical narrative analysis
Authors: Tambovtsev V. L.
Published: January 2023

The purpose of the article is to analyze the possibilities and feasibility of using narrative analysis methods in studying the structure and dynamics of entrepreneurial networks. To achieve it, the author provides the description of an entrepreneurial network concept, explores the results of its exploration in the world science, which leads to the conclusion that the use of purely quantitative methods to study entrepreneurial networks does not allow us to reveal their essential features determined by a number of practically unmeasurable social factors. One of these results is the correlation between the two blocks in entrepreneurial business networks: personal entrepreneurial networks that arise before the start of an individual’s business activity, and ordinary inter-firm interactions that begin to operate after the start of his business, usually in the form of the creation of his first firm. The first block is not affected by standard official statistics and requires different research methods. Based on this, the article discusses in detail the concept of narratives and methods for studying them in social sciences, with a special attention on narrative analysis in economics. Finally, the author characterizes the variants of such analysis, proposes and substantiates the logic and methodological features of its application to the study of entrepreneurial networks.
The analysis of space category in economic studies
Authors: Goncharova K. S. , Shelomentsev G.
Published: January 2023

Space is one of the key and controversial (in terms of content) categories in economics. It is assumed that the methodological basis of spatial development concept, and, correspondingly, the very concept of space itself are classical (mercantilism) and neoclassical (price theory) theories. However, until now the understanding of its nature and its role in creating and transforming modern socio-economic relations remains a debatable issue. The key method of analysis in this work is semantic analysis. The Authors attempt, on the one hand, to reveal a retrospective transformation of space concept, and on the other, to identify the key theoretical and methodological approaches to this phenomenon in modern research. The analysis results in a number of valuable findings. First, the authors identify a synthetic nature of concept evolution, which consists in a specific absorption of previously proposed models and space describing provisions. Secondly, the authors identify the main approaches to space study, for which the determining criterion is the nature of socio-economic relations formed by economic agents, and the processes that these agents implement in various spaces. Thirdly, the authors prove that modern concept of socio-economic space allows for a broader description of interactions of economic agents in translocation aspect. Thus, the scientific significance of the research consists in expanding knowledge approaches to defining the category of space, as well as its analysis in modern economic research.
A new view at the “Chinese model”: lessons for Russia, the Union state and the world
Authors: Merkulov K. K.
Published: January 2023

The paper provides a systemic-synergetic study — from a new conceptual stand — of the lessons of reform policy and openness to the outer world in the PRC after December 1979 through the lens of “the Chinese model” theory and practice for socio-economic, spiritual and materialistic progress of Russia, the new Union state (NUS) and the world at large. As a methodological basis of the work, the author first critically explores recent literature on this subject drawing on personal multi-decade research in this area. He then formulates a new conceptual view on the problem, provides a new periodization of the main socio-economic stages of development of the PRC; systematizes some of most important lessons of the “Chinese model” for Russia and the NUS; defines the current strategy of socio-economic development of the People’s Republic of China. The analysis concludes with an examination of the advancing socio-progress model towards a sustainable-optimal society, (bio)economy and (bio)finance and then the good-economic management. The findings will contribute to the development of optimal political economy and, more specifically, to a number of promising directions in the strategy of social sphere and the entire life order of Russia, the NUS and the world.

Published: January 2023

As an initial step toward in situ exploration of the interiors of Ocean Worlds to search for life using cryobot architectures, we test how various communication tethers behave under potential Europa-like stress conditions. By freezing two types of pretensioned insulated fiber optic cables inside ice blocks, we simulate tethers being refrozen in a probe’s wake as it traverses through an Ocean World’s ice shell. Using a cryogenic biaxial apparatus, we simulate shear motion on preexisting faults at various velocities and temperatures. These shear tests are used to evaluate the mechanical behavior of ice, characterize the behavior of communication tethers, and explore their limitations for deployment by a melt probe. We determine (a) the maximum shear stress tethers can sustain from an ice fault, prior to failure (viable/unviable regimes for deployment), and (b) optical tether performance for communications. We find that these tethers are fairly robust across a range of temperature and velocity conditions expected on Europa (T = 95–260 K, velocity = 5 × 10−7 m s−1 to 3 × 10−4 m s−1). However, damage to the outer jackets of the tethers and stretching of inner fibers at the coldest temperatures tested both indicate a need for further tether prototype development. Overall, these studies constrain the behavior of optical tethers for use at Ocean Worlds, improve the ability to probe thermomechanical properties of dynamic ice shells likely to be encountered by landed missions, and guide future technology development for accessing the interiors of (potentially habitable ± inhabited) Ocean Worlds.

Published: January 2023

We report on the observed fluxes of the comets detected by NEOWISE during the first year of operations after the spacecraft’s reactivation. The sample included 57 comets. Of the comets detected, 30 were short-period comets (27 Jupiter-family comets, 1 Centaur, 2 Halley-type comets), and 27 were long-period comets. From the measured fluxes in the two NEOWISE bands, proxies for the gas production and coma dust are derived. We find a relationship between heliocentric distance, perihelion distance, and the gas-to-dust proxy fractions.
Judith Butler e o leite de cabra nas mulheres Cariris em Crato-CE
Authors: Oliveira Junior Ribamar José de
Published: January 2023

Neste texto, trago breves reflexões sobre a narrativa das mulheres Cariris na comunidade de Poço Dantas-Umari, no distrito de Monte Alverne da cidade de Crato, no interior do Ceará. Ao levar em consideração as experiências da pajé Rosa Cariri, Nilza Cariri e Vanda Cariri, procuro pensar na dimensão performativa dessas narrativas a partir das histórias contadas naquele encontro, levando em conta as performances de gênero das mulheres ao longo do tempo por meio dos corpos que as recontam. Quando me afeto pela forma como o leite de cabra aparece no passado dessas práticas de memória, sobretudo, pelo contexto em que essa narrativa pode ser reapropriada no presente, lembro do pensamento de Judith Butler com a teoria da performatividade de gênero e questiono sobre quais materialidades e corpos podem importar para esse recontar. Próximo de um dos constitutivos do gênero dessas mulheres, o leite de cabra pode aparecer nessas narrativas como elo entre as temporalidades e a proliferação dos lugares de confluência das performances na matriz da colonialidade do gênero. Afinal, se o gênero é um feito, essas narrativas podem o desfazê-lo quando são lembradas, inclusive, provocando o debate sobre as relações de gênero e sexualidade nessa escrita da história dos povos Kariris.

Published: January 2023

Esta pesquisa tem como objetivo analisar os problemas que afetam a participação da mulher em jogos virtuais, de modo que se possa verificar como ocorre a sua participação na interlocução com o público masculino e quais seus efeitos. Uma pesquisa realizada pela Games Brasil, em 2019, a respeito do público nos jogos virtuais, indica 53% de mulheres. Apesar de serem maioria, fica claro o preconceito sofrido pelas mulheres nesse ambiente. Como forma de entender quais são os comportamentos hostis relacionados à presença da mulher no ambiente dos jogos on-line, foi aplicado um questionário a diversos grupos relacionados à cultura gamer. Ao todo, 529 pessoas responderam o questionário e mais de 80% dos respondentes relataram que já presenciaram ou vivenciaram comportamentos hostis no ambiente dos jogos virtuais. Apesar da presença desses comportamentos, as mulheres ingressaram em um espaço que, anteriormente, era predominantemente ocupado pelo público masculino e, assim, é necessário analisar as formas de combater a agressão e criar procedimentos adequados para lidar com esta situação.
Gênero e trabalho na construção civil
Authors: Rocha Manuela , Gitahy Leda
Published: January 2023

Esse artigo discute as relações entre gênero e trabalho na construção civil, por meio da comparação de estudos empíricos nacionais e internacionais. Observamos as características dessas relações em vários países (Reino Unido, Espanha, Escócia, Estados Unidos, Índia, Tailândia, Bangladesh, Turquia, Austrália, Peru e Nigéria) e no Brasil. A pesquisa demonstra a hierarquização e separação das tarefas, com a concentração de mulheres em funções que requerem atributos “femininos”, como a limpeza, os acabamentos e as atividades administrativas. A hierarquização foi observada por meio da desvalorização do trabalho feminino no âmbito técnico e socioeconômico. No caso do Brasil, as transformações evidenciam o aumento da participação de mulheres no setor, tendências de melhora na desigualdade salarial e o papel da construção na promoção da autonomia feminina.

Authors: Aumaréchal Laure , Lebeau Jean-Pierre , Lebleu Mary
Published: January 2023

Introduction : la pratique avancée infirmière a été récemment introduite dans le système de soins français, suscitant des réactions très variées des professionnels du soin. Beaucoup de travaux se sont intéressés aux bénéfices de l’infirmière en pratique avancée (IPA), aux étapes à suivre pour favoriser son implantation. Très peu, en revanche, ont exploré le ressenti des médecins généralistes (MG). L’objectif de ce travail était d’explorer les représentations, ressentis et attentes des MG d’une communauté professionnelle territoriale de santé (CPTS) vis-à-vis de la pratique avancée infirmière. Méthode : une étude qualitative avec une approche inspirée de la théorisation ancrée a été conduite, à partir d’entretiens semi-directifs, individuels ou en focus groups , auprès des MG d’une CPTS. Résultats : 12 MG ont été interrogés. L’analyse axiale a permis de construire et caractériser deux catégories : « Être deux » et « Définir le métier ». Discussion : les propriétés situées à l’intersection de ces deux catégories avaient notamment trait à la question du « pouvoir médical ».

Introduction : la langue et la communication sont essentielles à la sécurité des soins et à la gestion des personnes aux prises avec un trouble de santé mentale, en particulier lorsque ces personnes sont des minorités linguistiques. Objectifs/méthode : explorer ces réalités au sein d’une population en situation minoritaire linguistique en complément d’une revue de la littérature et des entrevues qualitatives. Les entrevues ont été menées à Ottawa, au Canada, auprès de patients francophones. Les études incluses dans la revue représentaient la littérature internationale sur les minorités linguistiques en général. Résultats : dans l’ensemble, les expériences décrites dans les articles publiés étaient semblables aux expériences vécues des participants, ce qui suggère que des obstacles aux soins existent, même dans les contextes ayant pour mandat de fournir des services dans les deux langues officielles. Discussion/conclusion : il y a de nombreux obstacles à la prestation de services de soins de santé mentale, et ce, quelle que soit la langue dominante. Toutefois, nous avons identifié comme distinct le sentiment intériorisé de responsabilité ressenti par les patients en situation minoritaire qui se sentent obligés de compenser ou de combler les lacunes linguistiques des prestataires.
Soins offerts aux personnes vivant avec le VIH : représentations sociales des infirmières dans un centre hospitalo-universitaire marocain
Authors: El Yahyaoui Sofia , Zeggwagh Amine Ali
Published: January 2023

Introduction : les représentations sociales (RS) des infirmières sur la maladie VIH-sida et les soins fournis aux personnes vivant avec le VIH sont diverses et différentes selon les contextes. L’étude vise la compréhension des RS des infirmières sur la maladie et sur les soins dispensés. Méthode : il s’agit d’une étude qualitative réalisée en 2018 auprès de 50 infirmières pratiquant dans 11 services spécialisés, relevant de sept hôpitaux universitaires marocains. Résultats : les RS des infirmières ont rappelé les débuts de l’émergence de la maladie VIH-sida avec certaines prises de positions sur sa conception clinique. Les soins prescrits ont été au cœur des représentations professionnelles, avec un intérêt néanmoins peu marqué pour les soins relationnels. Plusieurs conduites et émotions ont été représentées également autour de la relation soignant/soigné des infirmières face aux personnes vivant avec le VIH. Discussion : en milieu de soins, les RS sur la maladie VIH-sida et les soins dispensés donnent naissance à des modèles de soins et des relations qui vont au-delà des connaissances et capacités techniques. Conclusion : des actions d’engagement individuel portant sur les rencontres professionnelles et multidisciplinaires peuvent changer ces représentations et accompagner les infirmières dans l’intégration des soins de sensibilité, portant sur des affects positifs envers les patients.
The Incidence of Symptomatic Mediastinal Compromise Following Medial Clavicle Fractures

Published: January 2023

Medial clavicle fractures pose a concern for mediastinal compromise because of their proximity to the sternoclavicular joint. However, the true incidence of this complication is unknown. The purpose of this study was to evaluate fracture configuration and determine the incidence of mediastinal compromise following medial clavicle fractures. A retrospective analysis of all patients treated for isolated medial one-third clavicle fractures at a single institution was performed. Patient demographics, the mechanism of injury, complications, and treatment were recorded. The fracture pattern and orientation were determined from a review of injury radiographs and computed tomography scans. The incidence of subsequent mediastinal compromise was then identified via a chart review. One hundred five patients were included for analysis. Twenty-two patients (20.8%) had computed tomography scans for review. The average age was 56 years, with 53% of patients being male. Sixty-eight percent of patients reported a high-energy mechanism of injury. No patients demonstrated evidence of mediastinal compression on physical examination. No patients required hospitalization for complications secondary to mediastinal compromise. Ninety percent (n=94) of patients were treated nonoperatively. Forty-three percent of fractures were nondisplaced. The remaining fractures demonstrated anterior or superior displacement of the lateral fragment, with a 0% incidence of posterior displacement. The most common indication for surgery was fracture displacement (n=10). A classification of medial clavicle fractures was developed using data from our cohort and a literature review. Medial clavicle fractures rarely demonstrate posterior displacement. Despite fracture proximity, mediastinal injury is exceedingly uncommon. [

On the Rise: The Increasing Frequency of Pediatric Shoulder Stabilization Surgery in Children and Adolescents
Authors: Smith Haley E. , Morgan Allison M. , Patel Neeraj M.
Published: January 2023

The management of shoulder instability in children and adolescents continues to evolve. The purpose of this study was to evaluate the epidemiology of shoulder stabilization procedures in a large, nationally representative pediatric population. The Pediatric Health Information System (PHIS) database was queried for patients 18 years and younger undergoing surgical shoulder stabilization between 2008 and 2017. Patients undergoing arthroscopic surgery were compared with patients undergoing complex (open or bony augment stabilization) procedures. Annual trends were calculated using linear regression. A total of 3925 procedures were performed, of which 92.9% were arthroscopic Bankart repairs. There was a significant increase in overall pediatric shoulder stabilizations and arthroscopic repairs between 2008 and 2017. Complex procedures were performed most often in the Northeast, but the annual frequency did not increase nationally. [

The purpose of this study was to evaluate the effectiveness of telemedicine appointments in a tertiary orthopedic hip clinic during the COVID-19 pandemic, as a substitute for traditional in-person visits. One hundred sixty-three patients had a telemedicine visit from March to September 2020. Patients were divided into two cohorts. The presurgical group included all patients who had not undergone any prior surgical hip procedures. The pre-surgical group was further subdivided into two groups based on the purpose of the visit: conservative treatment and imaging review. Patients who were indicated for surgical treatment from these two groups were identified to assess their compliance with the surgical indication. The effectiveness was measured by assessing whether patients required an in-person visit before the scheduled follow-up after the telemedicine visit for further medical assessment. Fifty (30.7%) men and 113 (69.3%) women had a telemedicine visit during the 6-month period. The mean age was 43.68 (±16.95) years. There were 92 (56.4%) patients in the presurgical group, of whom 41% followed up after indication for conservative treatment and 59% visited to review imaging. From these groups, 27% were indicated for surgical treatment. The postsurgical group contained 71 (43.6%) patients, divided into three groups based on their surgery date: 0 to 3 months (27%), 4 to 12 months (59%), and more than 12 months (14%). All patients were compliant with the scheduled follow-up after their telemedicine visit. This study showed that telemedicine can be an effective tool for patient–physician communication, obviating the need for subsequent follow-up beyond regularly scheduled visits. [

Two-dimensional discrete-time laser model with chaos and bifurcations
Authors: Khan Abdul Qadeer , Almatrafi Mohammed Bakheet
Published: January 2023

We explore the local dynamical characteristics, chaos and bifurcations of a two-dimensional discrete laser model in $ \mathbb{R}_+^2 $. It is shown that for all $ a $, $ b $, $ c $ and $ p $, model has boundary fixed point $ P_{0y}(0, \frac{p}{c}) $, and the unique positive fixed point $ P^+_{xy}(\frac{ap-bc}{ab}, \frac{b}{a}) $ if $ p > \frac{b c}{a} $. Further, local dynamical characteristics with topological classifications for the fixed points $ P_{0y}(0, \frac{p}{c}) $ and $ P^+_{xy}(\frac{ap-bc}{ab}, \frac{b}{a}) $ have explored by stability theory. It is investigated that flip bifurcation exists for the boundary fixed point $ P_{0y}(0, \frac{p}{c}) $, and also there exists a flip bifurcation if parameters vary in a small neighborhood of the unique positive fixed point $ P^+_{xy}(\frac{ap-bc}{ab}, \frac{b}{a}) $. Moreover, it is also explored that for the fixed point $ P^+_{xy}(\frac{ap-bc}{ab}, \frac{b}{a}) $, laser model undergoes a Neimark-Sacker bifurcation, and in the meantime stable invariant curve appears. Numerical simulations are implemented to verify not only obtain results but also exhibit complex dynamics of period $ -2 $, $ -3 $, $ -4 $, $ -5 $, $ -8 $ and $ -9 $. Further, maximum lyapunov exponents along with fractal dimension are computed numerically to validate chaotic behavior of the laser model. Lastly, feedback control method is utilized to stabilize chaos exists in the model.
