Authors: De Rezende Paula Isabella , Santos Gomes Eulália , Clemente Villar Martini Veronica , Paulino do Nascimento Adriana
Published: September 2024

Introdução: Em indivíduos que tiveram baixo peso ao nascer pode ocorrer um período de aceleração do desenvolvimento para alcançar níveis considerados normais para a sua faixa etária. Isso corrobora para uma maior adiposidade, tendo como consequência a resistência à insulina, obesidade e diabetes tipo 2. Além disso, nessa condição, há alterações na formação renal causando uma hipertensão programada. Objetivo: identificar se há associação entre o baixo peso ao nascer e o desenvolvimento de doenças metabólicas como diabetes mellitus 2, obesidade, HAS e síndrome metabólica. Materiais e métodos: Para isso foram analisados, seguindo critérios de inclusão e exclusão, prontuários dos atendimentos realizados nos ambulatórios de cardiologia, endocrinologia e pediatria do UNIFAA e posteriormente seria averiguado na Maternidade Escola de Valença se os sujeitos apresentaram baixo peso ao nascer. Resultados e discussão: Foram analisadas 2207 fichas de atendimentos de acordo com os critérios de inclusão e exclusão, dentre as quais 160 possuíam as patologias de interesse. A principal evidência que aponta a relação entre o baixo peso ao nascer e o desenvolvimento de doenças metabólicas é a “programação fetal”, que ocorre na vida intrauterina e é diretamente influenciado pelas condições nutricionais maternas que gerarão uma resposta adaptativa no feto. Conclusão: Devido a obstáculos encontrados para o acesso aos dados dos nascimentos desses pacientes não foi possível a tomada de conclusões sobre a associação entre o baixo peso ao nascer e o desenvolvimento de doenças metabólicas. Entretanto, foi observado um número expressivo de crianças e adolescentes com as chamadas doenças crônicas não transmissíveis.

Published: September 2024

Kota Surakarta tidak terlepas dari adanya kerajaan besar yang bernama Kasunanan Surakarta dan sebuah Kadipaten yang tidak kalah hebatnya bernama Kadipaten Mangkunegaran. Dengan adanya dua kekuatan besar tersebut tentu saja banyak dikunjungi orang-orang dan utusan-utusan dari daerah lain maupun Manca Negara. Para pendatang tersebut ada yang sekedar datang dan pergi ada pula yang tinggal untuk menetap di kota kerajaan yang kesohor pada waktu itu. Mereka yang menetap selain berdagang biasanya juga melakukan siar agama Islam, terutama yang datang dari Hadramaut (Yaman), dan China Selatan. Waktu terus berjalan kekuatan kerajaan semakin besar dan semakin banyak para pengunjung yang datang merasa nyaman tinggal di kota kerajaan tersebut. Para pendatang tersebut lama kelamaan membentuk kelompok-kelompok sesuai dengan asalnya dan berada di sekitar kota raja tersebut. Mereka mulai membantu karaton dengan keahliannya masing-masing, sehingga raja memberinya tempat tinggal resmi yang bernama kampung karena raja merasa diuntungkan dengan kehadiran mereka. Untuk memudahkan mengontrol kehidupan sosial mereka, raja memerintahkan patihnya untuk memberikan nama kampung pada kelompok tersebut berdasarkan etnisnya, antara lain; kampung Pasar Kliwon yang dihuni oleh etnis Arab dan keturunannya. Kampung Pasar Kliwon masih sedikit yang meneliti bahkan belum ada yang meneliti secara arsitektural dan konservasi. Metode yang digunakan adalah analitik diskriptif dengan cara melakukan pengamatan lapangan, wawancara dengan beberapa orang yang tinggal di Pasar Kliwon dan mengikuti perkembangan kampungnya, serta para pakar yang faham akan kampung Pasar kliwon. Data yang didapat disusun kemudian disandingkan dengan beberapa literatur yang setara dan akan menghasilkan tentang identifikasi kampung Arab Pasar Kliwon di Surakarta.

Published: September 2024

Este artículo tiene por objetivo retomar la teoría de Byung Chul Han sobre la sociedad del logro (Leistungsgesellschaft), tomando específicamente lo expuesto por él sobre el dogma de la transparencia que surge en la lógica neoliberal-digital contemporánea, para ser completado con la teoría freudiana de lo Unerkante -no reconocible-. Para esto el trabajo se divide en tres momentos: el primero tiene por objetivo exponer lo que se entiende por dogma de la transparencia y cómo se relaciona con el Homo œconomicus; seguidamente, se presenta el concepto de lo Unerkante de Freud para plantear una nueva topología de lo no-reconocible en el plano subjetivo, proponiendo el concepto del ombligo de la subjetividad; y, finalmente, se expone cómo ese ombligo empalma con la teoría de Han frente a la transparencia, de modo que se puedan generar nuevas interpretaciones de lo que sería una salida a la sociedad del logro.

Published: September 2024

Introduction.  This study aimed to investigate the relationship between Achievement Goal Orientation, Self-Efficacy, and Academic Dishonesty among college students during online learning. 
Method.  A total of 238 students from students colleges in Indonesia completed an online questionnaire consisting of scales measuring Achievement Goal Orientation, Self-Efficacy, and Academic Dishonesty. The data were then analyzed using hierarchical regression analysis. 
Results.  The results showed a significant relationship between Mastery goal orientation (approach-avoidance) Performance avoidance orientation and Academic Dishonesty. Additionally, a significant relationship was found between Self-Efficacy and Academic Dishonesty, with students who had lower Self-Efficacy being more likely to engage in Academic Dishonesty compared to those with higher Self-Efficacy. Hierarchical regression analysis also revealed that Mastery goal orientation, Performance goal orientation, and Self-Efficacy together predicted Academic Dishonesty in college students during online learning.
Discussion and Conclusion.  This study concludes that Achievement Goal Orientation and Self-Efficacy are important factors that influence Academic Dishonesty in college students during online learning. These findings may contribute to the development of more effective online learning programs that encourage students to achieve honest and high-quality learning outcomes.
Improved Metallic Thermal Protection Systems for Reentry Vehicles: Thermomechanical and Impact Considerations
Authors: Le Vinh Tung , Goo Nam Seo
Published: September 2024

A design for a metallic thermal protection system (TPS) panel made of SS304 stainless steel was developed to withstand a simulated aerodynamic heating rate of [Formula: see text]. The TPS panel, which comprised an outer sandwich structure, thermal insulation material, stand-off brackets, and an interior base frame, faced challenges from its thermomechanical and impact properties. These challenges were addressed through a combined analytical and numerical approach, optimizing the design parameters, namely, deflection, low-velocity impact peak load, and weight balance, to enhance the performance of the sandwich structure. The results indicated consistency between the analytical and numerical models, effectively predicting deflection and initial peak load for the TPS design. The proposed TPS design was then manufactured and evaluated through both experimental and numerical analysis to assess its thermomechanical behavior. The underlying structure of the TPS panel remained within specified temperature limits, and the exterior sandwich structure demonstrated acceptable levels of impact energy. The experiment confirmed the feasibility of the TPS panel design, with no significant damage observed after 10 simulated flight missions. This study not only validates the proposed analytical method for initial TPS development stages but also confirms the viability of a SS304 stainless-steel TPS panel design for high thermal-stress environments, marking a significant step in advancing thermal protection technology.
Effect of Over-the-Rotor Liner on Fan Flutter Stability
Authors: Liu Chuanyang , Wang Xiaoyu , Gao Feng , Zhang Guangyu , Sun Xiaofeng
Published: September 2024

Previously published literature has proved excellent performance of the over-the-rotor acoustic liner (OTRL) in noise reduction. This work investigates the impact of the OTRL on fan flutter stability in a subsonic duct using a three-dimensional coupled singularity method. The effects of the axial position and the acoustic impedance of the liner on the fan flutter stability are examined. Results show significant near-field coupling between the acoustic liner and the rotor, affecting the unsteady blade loading distributions and intensifying as the liner and the rotor overlap axially. The fan flutter stability shows clear sensitivity to the liner’s acoustic resistance, while its dependency on acoustic reactance appears more complex. An energy-based analysis shows that secondary unsteady loading induced by rotor–OTRL interaction may inverse the phase of the total unsteady loading, thus affecting the fan flutter stability.
New Analytical Solutions for Free Vibration of Cracked Functionally Graded Rectangular Plates
Authors: Hu Zhaoyang , Shi Yueqing , Guo Chengjie , Du Jingyu , Li Rui
Published: September 2024

In aerospace engineering, the existence of cracks highly alters the mechanical behaviors of structural components. As a new class of key structural components, functionally graded material (FGM) rectangular plates with an interior/side crack are focused on in this study. New analytical free vibration solutions are put forward for such cracked FGM plates. First, a cracked plate is decomposed into several subplates with the necessary continuity conditions to address the physical discontinuity issue caused by the crack. The challenge then becomes deriving analytical free vibration solutions for each subplate. To accomplish this task, a symplectic superposition method (SSM) is developed to deal with FGM rectangular plates with various boundary conditions, including the complex continuity conditions. The SSM eliminates the need for a predefined solution form, and its solution procedure, including variable separation and eigen expansion, is mathematically rigorous. Afterward, the analytical solutions obtained via the SSM are integrated to serve as the final free vibration solution of the cracked FGM plate. Comprehensive results based on the obtained analytical solutions, including natural frequencies and vibration modes, are presented and validated. The solutions are further used to investigate the effects of some important parameters, such as crack length and crack location.

Authors: Hargis Joshua W. , Mussoni Erin E. , Swain William E. , Lynch Kyle P. , Wagner Justin L.
Published: September 2024

Measurements of carbon monoxide (CO) during air–carbon ablation of graphite are performed in the Sandia Hypersonic Shock Tunnel. Resistive heating is used to bring graphite samples to wall temperatures ([Formula: see text]) as measured by an imaging pyrometer. The heated models are subjected to a flow condition of [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]. Tunable diode laser absorption spectroscopy measures CO temperature and concentration within the boundary layer at 50 kHz. Ablation product concentrations from experiments are presented as a function of time, including the transient startup of the tunnel. The measured CO concentration increases by approximately a factor of 2 as surface temperatures increase from 1250 to 1630 K. Finally, the CO concentration is observed to be lower than that predicted by several air–carbon ablation models, with the best agreement occurring at the higher surface temperature.
Pressure-Sensitive-Paint-Driven Hybrid Unsteady Compressible Flow Simulation
Authors: Suzuki Takao
Published: September 2024

A hybrid unsteady compressible computational fluid dynamics simulation (CFD) driven by pressure-sensitive paint (PSP) data is proposed, and the concept is demonstrated in two dimensions. By imposing the wall pressure acquired with PSP as the Dirichlet boundary condition, an unsteady compressible Euler equation solver is marched together with integral boundary-layer equations in time. As a result, an entire flowfield that fits the PSP measurement is created in the CFD domain. This concept is tested by taking PSP data from a past article of a wind-tunnel test using the NASA CRM65 airfoil and the steady and unsteady capabilities of this data-driven hybrid simulation are demonstrated for transonic flows in two dimensions, and the convergence characteristics are also investigated. It is found that a steady shock position, which cannot be accurately predicted by the Euler equation solver with a boundary layer, can be rectified by the hybrid simulation. Moreover, unsteady shock motion due to buffeting can also be captured well by the hybrid simulation.

Research of the Possibility of Prediction of the Resource of Composite Structures Dased on the Results of Optical-thermal Nondestrousing Control Using Deep Neural Networks

Published: September 2024

В работе рассматривается проблема повышения достоверности оценки предельного срока эксплуатации многокомпонентных конструкций путем построения прогностических моделей с использованием в качестве входной информации результаты оптико-теплового неразрушающего контроля состояния объектов по температурным полям и величине внутренней деформации материала при силовом воздействии на конструкцию. Показано, что в случае применения логических подходов в качестве программного средства прогнозирования предельного ресурса конструкций из полимерных композиционных материалов, часть знаний должна использоваться для рассуждений, обеспечивающих объяснения выведенных заключений, поскольку формальная логика ограниченно применима, особенно в условиях неполной или неопределенной информации. В этом случае решением задачи становится выявление и установление причинно-следственных связей. Для задач технической оценки качества конструкций и ресурса их эксплуатации использование таких логических выводов, как индуктивные, дедуктивные и выводы по аналогии, невозможно, т.к. для своей работы они требуют наличия всей информации о диагностируемой конструкции.

The paper considers the problem of increasing the reliability of assessing the maximum service life of multicomponent structures by constructing predictive models using the results of optical-thermal non-destructive testing of the state of objects by temperature fields and the value of internal deformation of the material under force action on the structure as input information. It is shown that in the case of using logical approaches as a software tool for predicting the ultimate resource of structures made of polymer composite materials, part of the knowledge should be used for reasoning that provides an explanation of the conclusions drawn, since formal logic is of limited applicability, especially in conditions of incomplete or uncertain information. In this case, the solution to the problem becomes the identification and establishment of cause-andeffect relationships. For the tasks of technical assessment of the quality of structures and their service life, the use of such logical conclusions as inductive, deductive and analogous conclusions is impossible, since for their work, they require all information about the diagnosed structure.

Рассматриваются вопросы разрешающей способности оптического лидара по измерению фоновой концентрации метана в атмосфере как на приземных горизонтальных трассах с отражением оптического сигнала от природных объектов, так и на вертикальных трассах, когда оптический сигнал отражается от облачных слоев с экстраполяцией на низкие космические орбиты. С помощью моделирования показано, что в случае измерения с низкой космической орбиты время накопления сигнала может быть снижено до 1 с и менее в силу большого ослабления сигнала в центре линии поглощения в атмосферном столбе воздуха. За время накопления сигнала 1 с горизонтальное разрешение по горизонтальной координате составит ~8 км при орбитальной скорости спутника ~8 км/с. Разрешение по вертикали при измерениях с космической орбиты может составить ~1 км, если задаться точностью измерения уширения линии поглощения в ~0,006 нм (10 %). На приземных трассах экспериментальные результаты хорошо согласуются с результатами моделирования. Уширение линии излучения передатчика лидара в ~3 раза позволяет повысить излучаемую мощность на рассматриваемой длине волны ~1 653 нм, улучшить энергетический потенциал прибора и довести горизонтальное разрешение до 5…10 м при скорости движения луча лидара, соответствующей скорости перемещения вертолета.

The paper deals with the resolution of an optical lidar for measuring the background concentration of methane in the atmosphere both on surface horizontal paths with reflection of an optical signal from natural objects and on vertical paths, when an optical signal is refl ected from cloud layers with extrapolation to low space orbits. It was shown using simulations that in the case of measurements from a low space orbit, the signal accumulation time can be reduced to 1 second or less due to the large signal attenuation at the center of the absorption line in the atmospheric air column. For a signal accumulation time of 1 s, the horizontal resolution along the horizontal coordinate will be ~8 km at a satellite orbital velocity of ~8 km/s. The vertical resolution for measurements from space orbit can be ~1 km if the accuracy of measuring the absorption line broadening is ~0,006 nm (10 %). On the horizontal paths, the experimental results are in good agreement with the simulation results. Broadening the emission line of the lidar transmitter by a factor of ~3 makes it possible to increase the radiated power at the considered wavelength ~1 653 nm, improve the energy potential of the device, and bring the horizontal resolution to 5…10 m on the speed of lidar beam, corresponding to the speed of the helicopter.

В статье рассматривается роль норм адата в процессе воспитания дагестанской молодежи. Особо детально в статье уделено внимание морально-этической и патриотической стороне воспитания молодежи. Проводимая параллель между традиционным и современным воспитанием, показывает девальвацию традиционных устоев современным поколением дагестанцев. Этот факт придает актуальность данной теме. На основе исторических источников, полевого этнографического материала, автор приходит к выводу, что испокон веков кумыки руководствовались адатом, Последний во многих вопросах (суд, кровная месть, бракоразводный процесс) имел ярко выраженные правовые очертания, в других вопросах (воспитании подрастающего поколения, семейного быта) был зафиксирован в сборниках адата как этнографическая норма, то есть не имел юридическую силу. При этом игнорирование их исполнения влекло за собой самое страшное наказание – общественное порицание.

В статье приведены результаты расчета механического и сейсмического действий подземных ядерных взрывов, проведенных на глубине более километра. Проводится сравнение результатов моделирования, проведенного с учетом действия литостатического давления, с данными регистрации параметров сейсмовзрывных волн при известных экспериментах на о. Амчитка (США): «Cannikin» (глубина расположения заряда H = 1791 м) и «Milrow» (H = 1219 м). Кроме того, выполнены расчеты максимальных значений относительного коэффициента изменения проницаемости горного массива в ближней зоне взрыва. Показано, что применяемые при численном моделировании механического и сейсмического действий взрыва методы удовлетворительно описывают параметры сейсмовзрывных волн и конфигурацию зоны нарушенного взрывом материала. При этом результаты расчета не несут количественной информации о степени повреждения массива и изменении его интегральных свойств. Тем не менее, использование установленных ранее корреляционных зависимостей позволяет оценить такие свойства как поствзрывные: проницаемость, скорость распространения колебаний, степень раскрытия образовавшихся трещин и т.д. Результаты таких оценок могут быть использованы в качестве исходных данных при моделировании целого ряда физических задач.

The article presents the results of calculations of the mechanical and seismic effects of underground nuclear explosions carried out at a depth of more than a kilometer. A comparison is made of the modeling results, carried out taking into account the action of lithostatic pressure, with the data of recording the parameters of seismic explosion waves during known experiments on the island Amchitka (USA) «Cannikin» (explosion depth H = 1791 m) and «Milrow» (H = 1219 m). In addition, calculations were made of the maximum values of the relative coefficient of change in the permeability of the rock mass in the near zone of the explosion. It is shown that the methods used in the numerical modeling of the mechanical and seismic action of an explosion satisfactorily describe the parameters of seismic waves and the configuration of the zone of material destroyed by the explosion. At the same time, the calculation results do not provide quantitative information about the degree of damage to the massif and changes in its integral properties. However, the use of previously established correlation dependencies makes it possible to evaluate such properties as post-explosion permeability, seismic waves propagation velocities, apertures of fractures opening, etc. The results of such estimates can be used as input data when modeling a number of physical problems.
Organisation of consumer accounting as a promising direction of accounting and analytical support for strategic management
Authors: Adamova G. A.
Published: September 2024

The research purpose is   to study the problems of  accounting and analytical support for profit management of the company on the basis of  the organisation of  сost and income accounting in  the context of  consumer groups. In  connection with the growth of   the share of   expenditures for promotion of   products to   the market and service, in  the work, the necessity of   сreating management accounting in   terms of   consumers being the company’s clients has been substantiated. Identification of   them as  objects will allow to  determine who causes the greatest costs of an economic entity, but does not bring enough profit, so   is not profitable. The possibilities of   such accounting have been examined to   achieve the objective of  strategic client assessment. The organisation stages of   the management accounting for consumers have been allocated, including ways of  grouping them for further analysis. The factors that determine the value of   clients for an  economic entity have been identified. The dependence of   the level of   the company’s costs on   the types of   activities related to   consumer service has been substantiated. Recommendations have been made on   the use of   intensive, operational, and temporary cost drivers to   allocate expenditures among consumer groups and determine their profitability for the company. The article offers the application of   a   client assessment matrix in  order to   identify strategically important consumers and those with whom it   is not worth maintaining long-term relations. In  conclusion, the possibilities of   using data of   the consumer accounting for management purposes are given.
Tax potential of municipalities as the basis of regional budgets
Authors: Zotikov N. Z.
Published: September 2024

In  the Russian Federation (hereinafter referred to  as RF, Russia), which is  a  federal state with a  three-level budget system, it  is assumed that there is   tax potential at   all levels: federal, regional, and local. With the help of  taxes, the financial basis of   local governments is  formed and the socio-economic development of   municipalities is  ensured. In   developed countries, municipal budgets are formed mainly from the taxes assigned to   them. In   Russia, they continue to  remain the most problematic link in  the country’s budget system. The purpose of   the article is   to study the influence of  the taxes assigned to   local budgets on   the formation of   the tax potential of   the municipalities. Objectives are the following: analysis and assessment of   revenues of   the Russian local budgets in  dynamics, justification of  directions for increasing the tax potential. The methodological basis of   the research is   founded on a  systematic approach, within which the following methods have been used: analysis and synthesis, generalisation, grouping, tabular method, etc. The research has found that over the past years, with the introduction of  the Tax Code of   the RF, problems of   insufficient tax and non-tax revenues remain for most municipalities, low level of   the tax potential and predominance of   interbudgetary transfers in  their budgets are current. Due to  the increasing centralisation of   the tax revenues, the degree of   dependence of   the municipalities on   the federal centre is  high. Without actually enhancing the tax potential of   the municipalities, the development of   the regional economy is   impossible. The re -search results can be   used in   practice when developing economic policy for municipal development.
Financial uncertainty of a startup
Authors: Yusupova G. R. , Nesmeyanova E. I.
Published: September 2024

This article discusses the transformation of   the system of   attracting investments in  startups. The process of   finding an  investor for a   startup has had a   difficult path of  formation in   recent years. An  entrepreneur’s interest in   different sources of   investment is  associated with determining their possibilities for implementing the chosen business idea. For various purposes, businesses need different types of  investments: loans, credits, sale of   shares or   stocks. The search for an   investor for a   startup and their attraction is   associated with specific requirements for an  entrepreneur, which are practically not written about in  the media and advertised. The article focuses on   the types of   finance involved in   business. The issues of  the difference between grant financing of a   startup and the process of   searching and attracting an   investor are raised, since the requirements from the grantee fundamentally change the requirements for specialists who should be  involved in   the work and the requirements for maintaining the financial stability of  an organisation. The authors also consider the professional platforms for investors that have developed in   Russia and the forms of   investment relations: in   exchange for receiving a   share of   profits; in   exchange for a   share of   the proceeds.
Features of consumer perception of product innovations
Authors: Aleksandrova I. Yu.
Published: September 2024

The article examines the phenomenon of  consumer perception of   product innovations in   order to  identify features determined by   modern market conditions. The purpose of   the study is   achieved by   analysing the specifics of   customer perception of: the degree of  product innovativeness; product innovations in   the framework of  information overload and amid high intensity of   their introduction to  the market. As a   result of   the research, the following features of   the сonsumer perception, characteristic of   modern market conditions, are identified: subjectivity of   perception of   the product innovativeness; actualisation of  the phenomenon of  information neglect in  conditions of   information overload of   consumers and the phenomenon of   consumer stupor within the framework of   high intensity of   product innovations being introduced to   the market. The work proves the need to   study the psychology of   perception of   innovations by   potential consumers in  the process of   developing and introducing a   new product deeply and comprehensively, in   particular, to  study cognitive, value, need-motivational systems as   well as  the characteristics of   behaviour patterns of   consumers of   innovative products. Only in   this case it  is possible to  create a  product innovation that is   truly needed and therefore quickly and easily accepted by  the market.
ESG principles for increasing the efficiency of the oil and gas complex
Authors: Gorshkov S. A.
Published: September 2024

The research purpose is   to determine the possibility of   applying ESG principles in   the process of   forming development prospects for modern Russian oil and gas organisations from the perspective of  an ecosystem approach. The subject of   the study is  tools for increasing efficiency. The methods of  content analysis, synthesis and verbal modelling have been used. It   is shown that the orientation of  the country’s oil and gas complex to  ensure the sustainability of   social and corporate governance while preserving the ecology of   the environment helps to  increase the efficiency of   the complex in  the future. In   this case, it   will receive competitive advantages which can be  appreciated by   investors who organise the attraction of   financial and information resources as  well as   human, material and energy resources. The novelty of   the results obtained lies in   the substantiation of   the approach that is   founded on a   combination of  such categories as  ESG principles, sustainable development, ecosystem approach, and strategic management. The results of  the study prove the feasibility of   applying the ESG principles as  tools which ensure the sustainable development of   modern Russian oil and gas organisations based on  the ecosystem approach in  the process of   searching solutions to   increase the efficiency of  the core activities. The approach contributes to  the formation of a   specific ecosystem where within the framework of  its development strategy the efficiency of   both a   network of   technologically related organisations and organisations that produce complementary goods and provide infrastructure services to   the entire oil and gas complex is   guaranteed.
