A Knowledge-Based Approach to Physical Education: A Systematic Review

In the current period, there is a growing interest in finding solutions for the new generation to have a more physically active life. One of the main tools we can act is the physical education lesson. Purpose: This paper aimed to find out if there is a new approach to the physical education class, one with a much more pedagogical (knowledge-based) character than the traditional approach based on competition and physical performance (sport-based). Method: Based on the PRISMA statement’s guidelines, several 105 papers were selected. Results and Discussion: The most commonly used terms to describe this new approach are: "physical literacy", "conceptual physical education" and "fitness education". The main role of this knowledge-based approach is to complete the practical activity and not to replace it. To achieve this, the theoretical component of physical education provides the student with knowledge of concepts, principles and methods, essential for effectively managing physical activity. The last part of the paper presents the main barriers that make teachers reject this knowledge-based approach.

MODALITY AS A TOOL OF AUTHORIAL PRESENCE IN PAKISTANI ENGLISH NEWSPAPERS

This study explores how modality is used in editorials related to Covid-19 from two Pakistani newspapers, to establish the author's presence in the text. A purposive sampling technique was used to select 50 editorials, and a concordance tool was employed to categorize the data. Modal verbs and other linguistic elements with modal meanings were analyzed using the interpersonal metafunction, as per Halliday's Systemic Functional Linguistics. The findings indicate that editorial writers predominantly employed modal verbs of prediction such as 'will' and 'would' when discussing the pandemic, and generic phrases were frequently used to express an objective, explicit orientation of modality. The fact that predictive modals are utilized in editorials implies that the main aim of the writers is to forecast upcoming occurrences. Additionally, the study found that the editors from both newspapers showed an equal interest in finding solutions to the pandemic by using obligatory modals such as 'should' and 'must'. It was found that the editors employed various linguistic techniques, including modality, in their editorials with the aim of impacting and molding the way readers view the pandemic. Keywords: modality, authorial presence, modal expressions, modal verbs.

Research progress on antibiotic resistance of Salmonella

Abstract Antibiotic abuse results in various antibiotic resistance among a number of foodborne bacteria, posing a severe threat to food safety. Antibiotic resistance genes are commonly detected in foodborne pathogens, which has sparked much interest in finding solutions to these issues. Various strategies against these drug-resistant pathogens have been studied, including new antibiotics and phages. Recently, a powerful tool has been introduced in the fight against drug-resistant pathogens, namely, clustered regularly interspaced short palindromic repeats-CRISPR associated (CRISPR-Cas) system aggregated by a prokaryotic defense mechanism. This review summarizes the mechanism of antibiotic resistance in Salmonella and resistance to common antibiotics, analyzes the relationship between Salmonella CRISPR-Cas and antibiotic resistance, discusses the changes in antibiotic resistance on the structure and function of CRISPR-Cas, and finally predicts the mechanism of CRISPR-Cas intervention in Salmonella antibiotic resistance. In the future, CRISPR-Cas is expected to become an important tool to reduce the threat of antibiotic-resistant pathogens in food safety.

Импортозамещение информационно-коммуникационных технологий в России

The spatial development of the region ensures the stability of the entire socioeconomic system in the long term, determining its resistance to the effects of external shocks, increasing the ability of the regional economy to recover from these shocks. This explains the increased interest in finding solutions to the problems of a sustainable spatial development of Russian regions in modern conditions. According to the provisions of strategic management, the sustainability of economic systems, in turn, depends on internal factors: on the economic structure and features of development, on the quality of institutions, on the balance of development of economic, on social and environmental factors of the functioning of society under existing resource constraints. The stability of the region's economy largely depends on its ability to withstand the influence of negative factors in times of crisis. At the same time, despite the theory of cyclical economic crises, each of them has its own nature and form of manifestation. The stability of the spatial development of the region is a function of the factors of its instability. Therefore, special attention must be paid to factors that increase instability and reduce the stability of the region's economy, turning its relatively stable system into an unstable one, unable to ensure the unity of socioeconomic, institutional, and environmental development. During this period, there is a reduction in the resource potential of the region, which is unable to meet the vital needs of people living in the region, to create zones of their favorable residence in these territories. The group of internal factors of instability should include, first of all, the decline in production in the region, the growth of inflation, the outflow of the population, weak entrepreneurial and investment activity, the reduction in effective demand, monopoly, etc. The factors of the instability of the economy of the regions are, first of all, external ones, since in the modern conditions of globalization the spatial development of each region is characterized by an increasing strengthening of interdependencies at the interstate, national, and regional levels, manifested primarily in the transformation and restructuring of the economy, strengthening of international institutions of influence, homogenization and convergence of economic and social relations. Modern realities necessitate the improvement of appropriate protective anti-shock mechanisms that ensure the economic sustainability of the development of the socioeconomic space of the regions and the Russian Federation as a whole. The aim of this study involves consideration of new challenges to the sustainability of the spatial development of the region, which is considered on the example of Perm Krai.

Test bench for studying the effects of water injection inside an internal combustion engine

Under the increasingly drastic conditions imposed on motor vehicles, in terms of pollution, manufacturers and researchers are looking for solutions to reduce pollutant emissions, especially emissions of nitrogen oxides (NOx) dissipated in the atmosphere. The problem of polluting emissions in the field of transport is becoming increasingly stringent, the pollution rules are becoming stricter, so there is a general interest in finding solutions to reduce pollutant emissions and fuel consumption. A possible solution to this problem can be achieved by direct or indirect water injection (through the valve port) inside the cylinder of an internal combustion engine. In this paperwork we present the test bench and we analyzed the effect of water injection inside a cylinder of an internal combustion engine. The water injection is made upstream of the throttle valve by single injector mounted on the intake. The injection timing and amount of water injected inside the engine have been controlled by CompactRIO hardware device and in-house algorithm implemented in LabView. The engine used for measurements is a 1.6 liter engine, manufactured by Daewoo Motor Company and for the moment it’s running on wasted spark configuration. So in order to have water particles in all the cylinders, the water is injected two times at each rotation of the crankshaft. The main goal of this research was decreasing of nitrogen oxides (NOx) by reducing the combustion chamber temperature.

Redundant-Configuration Scrubbing of SRAM-Based FPGAs

Static RAM-based field programmable gate arrays (SRAM-based FPGAs) are widely adopted in trigger and data acquisition systems of high-energy physics detectors for implementing fast logic due to their reconfigurability, large real-time processing capabilities and embedded high-speed serial IOs. These devices are sensitive to radiation-induced upsets, which may alter the functionality of the implemented circuit. Presently, their usage on-detector is limited and there is a strong interest in finding solutions for improving their tolerance to radiation-induced upsets. In this paper, we show a novel configuration-redundancy generation and scrubbing technique for SRAM-based FPGAs. It leads to a power saving with respect to other solutions in the literature. Moreover, our technique is compatible with several Xilinx FPGA families. Our solution does not require neither the usage of external memories nor third-party layout tools. We describe an example of our solution applied to a benchmark design implemented in a Xilinx Kintex-7 FPGA. In order to prove the effectiveness of the solution, we present results from a proton irradiation test.

Energy harvester for a wireless sensor in a boiler environment

Wireless sensors have become a focus of study in the field of measurement technologies. The power supply of many wireless sensors is based on batteries or external power sources. However, there is increasing interest in finding solutions where the batteries can be leaved away and the power for the wireless sensors is produced from the environment in which the sensors operate. The technologies required are called energy harvesting or scavenging technologies.This paper introduces the principles, modeling and a practical implementation of a self-powering solution for a wireless sensor for energy boilers or other hot reactor vessels. With the aid of energy solution introduced, the wireless sensor can operate autonomously without any batteries. One of the design targets in this work was that the top part of harvester’s mechanics must fit to the opening or assembly tube of diameter less than 15mm in the boiler wall reserved for standard instrument assemblies. So the top of harvester collects and conducts thermal energy to element generating electricity from it. The harvester and further the measuring and communication electronics are mounted outside the hot area.The harvester solution introduced in the paper can produce about 114mW power, when top of harvester mechanics was inserted to the test oven heated to temperature of +500°C. The sensor function or type is not defined nor limited in this study. The electric energy generated by harvester can be used to power, for example, temperature, heat flux, flow, vibration or other little energy needing sensors.

Control of Tokamaks using ASTRA – Matlab Integration

The need to find new sources of power has emerged as an important issue due to the existing worldwide increase in the demand of energy. In this way, nuclear fusion has turned out to be a promising source of this power which has lead to an increasing interest in finding solutions for the different tokamak control problems. In order to find appropriate controllers for tokamaks several kinds of codes and models have been developed. In this paper one of those codes, ASTRA, is used to simulate the performance of a tokamak. The aim of this paper is to show how the ASTRA code for tokamaks can be integrated into the Matlab – Simulink tool with the purpose of making more convenient and easier the development of suitable controllers for tokamaks. In particular as a demonstrative case study, a simple PID controller has been designed for the loop voltage of a tokamak. The simulations obtained from the example presented in this manuscript show the feasibility and the goodness of the proposed ASTRA – Matlab integration. This integration composes a new and innovative issue in the tokamak control area and it provides new possibilities to the development and application of advanced control schemes to the standardized and widely extended ASTRA simulation code for tokamaks.
