OBJECTIVE: To determine if participants demonstrate distinct trajectories of step count following total knee replacement, and whether their baseline characteristics differ. DESIGN: Longitudinal repeated measures study within a randomized-controlled trial. METHODS: Participants were recruited from 3 hospitals in Sydney, Australia. Only participant data from the intervention group were used for this study (n = 51). Baseline data including demographics, pain (0-10 numerical rating scale), 13-item Patient Activation Measure scale, and modified Computer Self-efficacy Scale were collected. Participants received an activity tracker to monitor daily step counts. Latent class analyses were used to identify distinct trajectories of step count from baseline to 3-month follow-up. Baseline characteristics were compared using multinomial logistic regression. RESULTS: 43 participants were included in the analysis. Participants were predominantly female (n = 30, 70%) with an average age (SD) of 67.7 (7.5) years and body mass index (SD) of 30.3 (6.0). Three distinct step count trajectories were identified: a “high and rapidly increasing” group (n = 6, 14%), who began at 6251 ± 3508 steps and achieved 12794 ± 3173 steps by weeks 9 to 11; a “low and gradually increasing” (n = 24, 56%), (baseline: 2843 ± 1058 steps, 12 weeks: 6441 ± 1677 steps) ; and “high and gradually increasing” (n = 13, 30%), (baseline: 6299 ± 1777 steps, 12 weeks: 9614 ± 1436 steps). At baseline, body mass index and pain significantly differed between groups. CONCLUSION: Three distinct step count trajectories were found in people with total knee replacement. Findings highlight the variability between patient groups and the need for support for those who may not be reaching prescribed step goals. JOSPT Open 2023;1(1):78-85.

Published: September 2024

Рассмотрены основные аспекты концепций человеческого капитала, инновационных проектов и имитационного моделирования, на основе чего предложена имитационная модель, описывающая роль человеческого капитала в инновационных проектах. Разработанная модель высокого уровня абстракции создана для исследования роли социального компонента в организационной структуре инновационного проекта в общем контексте (на уровне отрасли, предприятия, части предприятия) и рассматривается прежде всего как инструмент для отслеживания динамики проектов с учетом состояния человеческого капитала системы. Модель состоит из двух основных частей: базовой имитационной модели, выполненной на языке системной динамики, и агентного компонента модели, описывающего динамику человеческого капитала. Модель представляет собой концептуальный инструмент, требующий калибровки и доработки для применения к конкретной организации.
The main aspects of three concepts––human capital, innovation projects, and simulation modeling––are considered, and a simulation model is proposed to describe the role of human capital in innovation projects. This high-level abstraction model is intended to study the role of the social component in the organizational structure of an innovation project in a general context (at the level of an economic sector, an enterprise, or part of an enterprise). It is treated primarily as a tool for tracking the dynamics of projects considering the state of human capital of the system. The model consists of two main components, namely, a basic simulation model in system dynamics terms and an agent-based component of the model describing human capital dynamics. The model is a conceptual tool that requires calibration and refinement when being implemented in a particular organization.

Authors: Макаров М.И. 
Published: September 2024

Представлен алгоритм локального планирования пути в системе координат дорожного полотна. Он основан на варьировании точек исходной траектории с применением метода потенциального поля и обеспечения гладкости получаемого пути относительно новой системы координат. Реализация алгоритма основывается на решении задачи минимизации целевого функционала. Рассматривается решение задачи применительно к планированию пути беспилотной транспортной платформы, для чего требуется изменять участки заранее подготовленной гладкой траектории движения транспортного средства в режиме реального времени с учетом возникающих препятствий и с сохранением гладкости. Использование новой системы координат дает преимущество во времени выполнения алгоритма по сравнению с его работой в декартовой системе координат. Алгоритм реализован на языке Python. Выделение горизонта планирования позволяет сочетать предложенный подход с различными алгоритмами следования по пути, которые сами по себе не реализуют методы обхода препятствий. Численное моделирование выполнено для характерных примеров, по которым можно оценить эффективность предложенного алгоритма.
This paper presents a local path planning algorithm in the coordinate system of the roadbed. The algorithm is based on varying initial trajectory points using the potential field method and ensuring the smooth resulting path in a new coordinate system. This algorithm is executed by minimizing an objective functional. The problem is solved with application to path planning for an unmanned transport platform: it is necessary to change the vehicle’s global smooth trajectory points in real time while maintaining smoothness and avoiding emerging obstacles. Compared to the Cartesian coordinate system, the new coordinate system is advantageous in terms of the execution time of the algorithm. The algorithm is implemented in Python. With a planning horizon being specified, this approach can be combined with various path-following algorithms that have no obstacle avoidance methods. Computer simulation results are provided to demonstrate the effectiveness of the proposed algorithm.

Аннотация: Данная статья актуальна, так как процессы слияния и поглощения в период санкций и ухода с российского рынка иностранных компаний дают возможность развития новых процессов в данном направлении. В статье анализируются процессы слияния и поглощения на основе российской практики. Показаны изменения данных процессов в связи с вводимыми санкциями и влияния на них внешнеполитической обстановки. Авторы затрагивают вопросы роли государства в процессах слияния и поглощения, вызванные новой геополитической обстановкой и положением на российском товарном рынке. Авторами проведен анализ данных процессов в 2021 году и особенности M&A в первой половине 2022 года. В работе рассмотрена роль государства на рынке слияния и поглощения. Как правило она заключается в организации функционирования правовых институтов, арбитражных судов, а также принятии антимонопольных актов. Государство помимо законодательной поддержки и контроля само может выступать актором на рынке слияния и поглощения. Поддержка государства данных процессов в последние месяцы очевидна. Для эффективного функционирования рынка слияния и поглощения необходимо регулирование через взаимодействия спроса и предложения, а также создание государством правовой базы для формирования и поддержания институтов, координирующих данные процессы.

Imagining a Fuller Potential for Plain Language Summaries: A Case study of Canadian Science Publishing
Authors: Bowker Lynne 
Published: September 2024

Researchers are increasingly encouraged to produce plain language summaries, but are they doing so, and do these summaries meet the expectations laid out in the guidelines for preparation? To learn more about the use of plain language summaries in scholarly communication in Canada, we conducted a case study of Canadian Science Publishing (CSP), which publishes 23 journals across a range of scientific domains. The case study reveals that while the number of authors who generate plain language summaries of their research has increased steadily since CSP introduced this option in 2016, the percentage is still relatively low. In addition, the plain language summaries that are produced show similar readability scores to the scientific abstracts. We conclude by offering a number of recommendations that CSP could implement to increase the adoption and improve the readability of plain language summaries.

Published: September 2024

The purpose of this research is to examine and answer questions regarding the existence of Auxiliary State Organs as a state institution within the constitutional structure in Indonesia. The distribution of powers to special branches in a state of law is aimed to avoid centralized bureaucracy which tends to cause irregularities in issuing policies. Indonesia in its context does not apply trias politica purely with implications for the emergence of independent institutions which were not known in the previous era. The independent institutions referred to are usually referred to as state auxiliary institutions or auxiliary institutions which mean supporting state institutions. Among these institutions, sometimes there are also what are referred to as independent regulatory agencies, independent supervisory bodies or state institutions that carry out mixed functions. In the context of the history of Islamic politics, independent state institutions have significant relevance to what was implemented by the Prophet Muhammad, and the khilafah period after. The type and approach of legal research that will be carried out in this research is normative juridical/normative legal research, a research that is devoted to studying the principles or norms in positive law. The existence of auxiliary state organs is very important in carrying out government duties and maintaining state stability. In addition, this institution also has special duties and functions to support and support the implementation of the main institutional duties in Indonesia.
The influence of radiant heat loss on the melting conditions of a material with internal heat release
Authors: Donskoy I. G. 
Published: September 2024

The RELEVANCE of the study lies in obtaining approximate analytical and numerical solutions for the problem of estimating the thermal state of thermal power equipment elements, such as thermal storage units and promising chemical reactors.The PURPOSE is to investigate the behavior of stationary solutions of heat conduction equations system in a space domain with internal heat release; to determine the conditions for the start and completion of melting, as well as the dependence of these conditions on the intensity of radiant heat loss at the outer boundary; to study the influence of individual factors on the phase boundary position.METHODS. Numerical methods are used: for a known type of solution, the coefficients are determined in such a way that the boundary conditions (in the general case, nonlinear) are satisfied. Newton's method is used to find the coefficients.RESULTS. The relationships between heat transfer parameters (convective and radiant heat transfer coefficients) and the phase transition boundary position in a cylindrical sample are obtained. These dependences allow to determine the critical values of the heat release intensity corresponding to the beginning of the sample melting (appearance of the liquid phase) and the complete sample melting (reaching the melting temperature at the outer boundary). These dependencies are compared with approximate formulas to assess the range of applicability of the latter.CONCLUSION. The presented calculations give the conditions for the beginning and end of melting of the heat-generating material. The conditions for complete melting of the sample can be determined accurately. The conditions for the onset of melting are obtained in the form of a nonlinear equation, the only physical (i.e., real and positive) root of which gives the critical value of the heat release intensity. In a linear approximation, a simplified formula can be obtained that relates the critical value of heat release intensity to radiant heat loss.

Published: September 2024

Despite the large volume of large-panel and monolithic construction in modern cities, the level of aesthetic requirements for house construction using new finishing building materials also leads to an increase in the demand for ceramic bricks. To solve the problem of the national project “affordable housing” it is necessary to increase the production of locally produced ceramic bricks. To do this, it is necessary to modernize existing brick factories or build new ones. In this case, it is desirable to use new technologies and production methods that ensure the quality of the produced bricks. The properties of bricks are mainly formed during the firing process, which at the same time is the most complex and heat-intensive production stage. The required quality of building ceramics largely depends on ensuring a certain temperature distribution during the firing process while moving cars with bricks along the tunnel kiln. Therefore, work devoted to ensuring the required temperature distribution in different zones of tunnel furnaces with different placements of gas burners is relevant from a practical point of view.THE PURPOSE of the work is to experimentally determine the temperature in different places of the tunnel furnace volume during the movement of the car in the operating furnace.METHOD. Temperature sensors with remote information transmission were placed on the brick cages of a carriage moving along the kiln, the signals from which were recorded by a multi-channel meter during the entire firing cycle. The measurement results are presented in the form of graphs of temperature dependences from various sensors depending on the time of the firing process. Based on the results of the experiments, conclusions were drawn regarding improving the quality of heat treatment of bricks and reducing production defects.

Published: September 2024

RELEVANCE this study is based on the need for the practical implementation of the national state strategy for environmental development, which allows for the functioning of the main sectors of the economy with low greenhouse gas emissions, taking into account global climate change, for a gradual transition to full carbon neutrality. Environmental protection policy in the field of environmental protection is aimed at limiting the entry of greenhouse gas emissions into the atmosphere through the development and improvement of organizational and technological measures. Thus, based on the formed strategy, energy enterprises can participate in conducting an experiment on quotas for emissions of pollutants in order to determine the standards for permissible greenhouse gas emissions into the atmosphere for boiler installations of thermal power plants.PURPOSE. The paper analyzes the legislative framework, regulatory and technical documents and methodological approaches to setting standards and evaluating technological indicators of greenhouse gas emissions into the atmosphere for boiler plants.METHODS. Calculations of carbon dioxide emissions into the atmosphere during the operation of boiler installations of thermal power plants using coal and natural gas as fuel (options) are performed in accordance with methodological recommendations based on balance equations. Mass and specific carbon dioxide emissions have been determined for the most common types of coal and natural gas used at Russian thermal power plants.RESULTS. Taking into account the composition and lower heat of combustion of fuel, input thermal power (50 MW or more) and thermal efficiency indicators of thermal power plants of various types, mass and specific carbon dioxide emissions in terms of a ton of natural and conventional fuel are calculated.CONCLUSION. The obtained research results can be used at energy enterprises and thermal power plants in the development of a program to improve environmental efficiency and justify participation in a state experiment on emission quotas, including a gradual transition to full carbon neutrality of the energy production process.

Published: September 2024

THE RELEVANCE of the research lies in the need to improve existing control systems for industrial mechanisms with minimal investment in reconstruction, as well as the demand for reliable control systems, the use of which can increase the service life of the device as a whole.THE PURPOSE. To develop a simple and at the same time effective control system for an industrial facility that allows damping vibrations of a flexible load. On overhead cranes, one of the mechanisms for moving cargo around the workshop is the trolley mechanism. The overhead crane trolley is used to move cargo along the bridge span, and the transported cargo can have either a rigid or flexible suspension. The use of a flexible suspension leads to vibrations in the form of rocking of the moved load. These vibrations are a negative phenomenon that has a negative impact on the mechanical structure of the crane and on the electrical control system of the electric drive of the trolley. An asynchronous motor with a squirrel-cage rotor is installed on the mechanism under consideration; based on the research carried out, a vector system was selected to control it, into which, in order to suppress load fluctuations, it was proposed to introduce a controller operating on the basis of fuzzy logic. The proposed fuzzy controller adjusts the engine speed depending on the angle of deflection of the flexible load; its uniqueness lies in its ease of implementation and the minimum number of control signals. Regulators of this type have proven themselves well, as they have high speed, good response in dynamics, and allow optimization of the control system by indirectly determining parameters.METHODS. During the study, mathematical modeling techniques were used to solve the identified problems. The study of the control system was carried out in the MATLAB modeling environment in the Simulink subsystem.RESULTS. The article reflects the significance of the research topic and discusses the available methods for damping vibrations of a flexible load. For the study, a system was developed containing a subsystem whose functions include tracking the dynamics of the movement of the cart and cargo. This article proposes a control controller operating on the basis of fuzzy logic rules. The controller is simple to implement, has one control signal, while fuzzy logic allows you to flexibly configure the control system, which makes it possible to obtain the required control characteristics.CONCLUSION. Simulation of the trolley operation process in the MATLAB Simulink environment took place with a change in the mass of the load and the length of the suspension; the analysis of all modeling options led to the conclusion that the proposed controller based on fuzzy logic makes it possible to dampen load fluctuations for various initial parameters.
