Authors: Palmieri Mayara , Fontes Daniel Trugillo Martins , Rodrigues André Machado
Published: August 2023

In this work we tackled the question of whether research articles that analyze school science textbooks are theoretically grounded when considering contextualization. To answer this question we conducted a systematic literature review of the formulations of the notion of contextualization developed in scientific research that analyze science textbooks. For the selection of journals, we used the information available in Brazilian Qualis Journals, rated A1 or A2 in the Teaching area, which has Science Teaching as their scope. The research resulted in a sample of 48 articles between 2004 and 2021. The methodological framework was based on content analysis. Among the results, we highlight five different contextualization approaches in research articles that analyze textbooks. Furthermore, we notice that the contextualization perspective is not conceptualized in any predominant theoretical framework, either in official documents or academic literature. This work offers a basis for understanding how Brazilian Common National Basis (BNCC) will influence contextualization perspectives and its reflection in academic literature.

Published: August 2023

Learning technologies are gradually taking center stage in the education system of the various economies and are becoming a dominant tool for teaching and learning in the various higher institutions of learning. Various forms of learning technologies have evolved in this 21st century with the notion of improving content management, lesson presentation, teachers’ portfolio building, curriculum design and management, assessment, teachers’ competencies development, and reaching the learner beyond the traditional face-to-face model of teaching have increasingly become pervasive within various forms of learning environments. Institutions of higher education are increasingly turning to these technologies to resource and support their teaching and learning environments under distributed circumstances, face-to-face or blended. However, before the widespread deployment of these technologies, information regarding the effective implementation of these all-important learning technologies are very sparse. This study is geared towards gaining a better understanding of the factors that would influence the effective integration of these learning technologies into the teaching and learning in the various colleges of education in Ghana as well as the challenges they are likely to face. This research employed a mixed method. Among the factors likely to influence technology integration in the various colleges as discovered by this research are: tutors’ attitudes toward new media, pedagogical knowledge, perceived ease of technological use, perceived usefulness of technological solutions, availability of technological resources, and motivation. Some of the challenges colleges are likely to face are lack of technological infrastructure, high cost of the internet coupled with low bandwidth, unstable power supply, lack of administrative support, curriculum overload, and lack of in-service training.

Unlike traditional currencies that rely on centralized such as banks or governments, cryptocurrencies have become popular due to its decentralized transactions. Decentralization takes advantage of no requirement for intermediaries, thus reducing transaction fees and processing times. However, investing in cryptocurrencies incurs risks and uncertainties due to price volatility and rapid changes. The fact that prediction of asset prices is complex due to the influence of multiple factors on price movements. This paper studied the technical factor to analyse the short-term returns of Ethereum (ETH) in the periods of 1-10 days. The historical data containing ETH closing price are collected from CoinGecko. The twenty-two indicators are chosen from Momentum, Volatility, and Sentiment factors as candidates to provide valuable insights in market trends. By calculating various indicators based on past closing prices, this study utilizes XGBoost, a powerful boosted decision trees ensemble, to discover patterns in previous trading. The model performance is evaluated using the multi-class AUC-ROC metric, which measures the accuracy of predicting three types of ETH returns: Downtrend, Sideway, and Uptrend. The results show that the models achieve accuracy scores ranging from 0.65 to 0.67. Moreover, the study emphasizes the importance of considering momentum indicators when making investment decisions in Ethereum.

This paper describes the process for the synthesis of chemically crosslinked copolymer hydrogels based on monomer 1-vinyl-2-pyrrolidone and comonomer vinyl acetate, using the varied content of ethylene glycol dimethacrylate as a crosslinker, by the free radical polymerization method with thermal initiation. The content of unreacted reactants after poly(1-vinyl-2-pyrrolidone-co-vinyl-acetate), p(VP-VA), hydrogels synthesis was examined using high-pressure liquid chromatography (HPLC) method. Structure characterization of the obtained p(VP-VA) hydrogels was performed using the Fourier transform infrared spectroscopy (FTIR). In this study, the influences of crosslinker content and temperature on the swelling behaviour of p(VP-VA) were studied. Quantities of unreacted comonomers and crosslinker, calculated in relation to the initial amount present in the reaction mixture, confirmed their successful conversion into p(VP-VA) hydrogels. These unreacted values of 1-vinyl-2-pyrrolidone (in range of 0.605-1.609%), vinyl acetate (in range of 2.486-4.798%), and ethylene glycol dimethacrylate (in range of 0.889-3.240%) were within acceptable limits, and they were removed from the final products. FTIR spectra were verified that the copolymerization process was performed, and chemically crosslinking of polymer chains occurred by breaking double bonds from the reactants. Obtained crosslinked copolymers could be classified in the class of negative-thermosensitive hydrogels because they can swell and pass through a phase transition when heated from the swollen state at 25ºC to contracted state at 80ºC.

SIMULATION OF CAPACITIVELY COUPLED RF DISCHARGE IN ARGON
Authors: Lisovskiy V. , Dudin S. , Shakhnazarian A. , Platonov P. , Yegorenkov V.
Published: August 2023

In this work, the axial profiles of the density of electrons and positive ions, the mean electron energy, the electric field strength, and the potential were obtained, both on average over the period and in dynamics. It was shown that argon discharges are dominated by ionization by electrons that gained energy by stochastic heating during the expansion of near-electrode sheaths. This ionization occurs in two pulses during one RF period. At low RF voltage between the electrodes, the role of Ohmic heating of electrons in the electric field in a quasi-neutral plasma increases, but the contribution of stochastic heating remains dominant. The time-averaged plasma potential was found to
increase non-linearly with the RF voltage between the electrodes Urf. It is shown that at low Urf values (when the RF voltage approaches the discharge extinction curve), the average potential  can reach Urf due to the axial redistribution of the instantaneous potential in the gap between the electrodes.

INVESTIGATION OF SPATIAL DISTRIBUTION OF METAL VAPOURS ADMIXTURES IN THE PLASMA OF AN ELECTRIC ARC DISCHARGE
Authors: Murmantsev A.
Published: August 2023

This work focuses on diagnosing the plasma in an electric arc discharge in an argon flow using optical emission spectroscopy. The method employed for determining the population of energy levels and the concentration of metal atoms based on the absolute values of emission intensity is described and validated. The experimental setup includes
a spectrograph and an RGB CMOS matrix as the emission registration device. By obtaining the absolute values of the spectral radiances of Cu I lines and considering the axial symmetry of the electric arc discharge, the local radiation intensity of these lines is determined. Radial distributions of copper atom concentrations are then calculated
using the absolute values of emission intensities and the radial distribution of the excitation temperature, which is determined using the Boltzmann plots technique. Two methods are employed for calculating the atom concentrations. The first method involves Boltzmann plots based on four spectral lines of Cu I and the corresponding excitation temperature. The second method determines the concentrations directly from the population of copper's energy levels, which are derived from the absolute values of emission intensity of the Cu I spectral lines. The results obtained from these two methods exhibit a coincidence of within 20%, supporting the recommendation of this technique for plasma diagnostics in electric arc discharges.

In order to improve the vibration and noise level of permanent magnet synchronous motor, based on the ANSYS workbench multi-physical field coupling platform, the motor structure is designed and simulated to optimize the vibration and noise of the motor. The spatial and temporal order of the vibration noise caused by the first order tooth harmonic is analysed, and the vibration noise caused by the first order tooth harmonic is reduced by slotting the rotor. By analysing the influence of rotor slots with different positions and different size parameters on the air gap magnetic flux density of the motor, the most suitable optimization method is found, and the optimization level of air gap magnetic flux density of rotor slots with different shapes under the same position and slot area is analysed and compared, so as to select the most suitable rotor slot shape. The simulation analysis shows that the air gap magnetic density and torque ripple of the optimized motor have been significantly improved, and the electromagnetic noise of 48-time order caused by 12 times the electromagnetic frequency of the motor in the 0 space order has been significantly reduced, which proves the reliability of the optimized scheme.

In applications such as industrial drive systems and power supply systems, the use of a three-phase voltage-source Rectifier pulse width modulation converter is becoming increasingly common. Examples of these types of applications include: Power Factor Corrections and the reduction of harmonics. The critical control requirements of an application involving a three-phase voltage-source Rectifier pulse width modulation converter are to achieve a unity power factor and to regulate the dc voltage. The unity power factor guarantees the highest possible efficiency, while the dc voltage regulation guarantees that the converter will operate as desired. In this study, a novel control method for stabilizing a Rectifier-Inverter pulse width modulation converter is designed and simulated to reach higher levels of stability while also improving dynamic performances. In the first step, the nonlinear equation system of the converter is transformed into a polytopic form. This is done with the help of the sector nonlinearity transformation. After that, a Takagi-Sugeno fuzzy controller that uses the parallel distributed compensation operating concept is applied. The design of the control system takes into account practical control requirements, such as a fast voltage tracking strategy and line-currents regulation. In order to obtain the controller gain, a series of linear matrix inequalities must be resolved. Simulations performed using Matlab/Simulink make it abundantly evident that the proposed method possesses excellent performance in terms of both voltage tracking control and unity power factor regulation.

PT Kereta Commuter Indonesia is one of the subsidiaries of PT Kereta Api Indonesia (Persero) which can be a solution for the community to answer urban transportation problems, especially the Jabodetabek area which is increasingly crowded and complex. However, users of public transportation services, including commuter line users, have to wait to get the service. Based on this background, this study focus is to discuss related to gate machine facility services and train services using concept of queueing theory. This research was conducted at Bekasi Station which has nine gate machines for check in with First Come First Serve service and four train platforms to serve the trains with Priority Service. The service model using Multiple Channel Single Phase service model. The result of this study indicate that the activity level of Indonesiaâ€™s Commuter Line service at Bekasi Station in term of check in is quiet high, while the train service has a low level activity so that the service system is not optimal. The level of activity in commuter line service can be more optimal if there is a reduction in facilities for the train service into three platforms that used in 09.00 â€“ 18.00 WIB at Bekasi Station

Eggshell is solid wastes produced from the food industry. Commonly, eggshell and its membrane used to treat water pollution such as heavy metal removal and also dye removal. Thus, on the treatment process, it’s was having the material handling problem, which was needed filtration method to remove out the adsorbent from the solution, and it was not efficient when commercializing in the wastewater treatment plant. Therefore, this study was using alcohol-sodium alginate (PVA/SA) to encapsulate the eggshell membrane, and this encapsulation method also would be able to enhance the performance of raw material on the dye adsorption. In this study, the eggshell membrane (ESM) are prepared in bead form, and the optimization of the bead are performed by the removal of congo red dye at several parameters such as pH, initial dye concentration, contact time, and dosage of ESM. The central composite design was selected to optimize the adsorption process by generating 30 runs of the experiment using software Design Expert® version 11. The Fourier Transforms Infrared Spectroscopy (FTIR) analysis and Brunauer-Emmett-Teller (BET) analysis are used to characterize the ESM bead. There was found out that main functional group on ESM bead contribute on adsorption process were carbonyl group, hydroxyl group and ESM bead also having the 42.74 nm of pore size. The optimize point for each parameter was 12.63mg/L of initial dye concentration, 6.12 g of ESM dosage, pH 2.19 and 12.83 min of contact time and the optimum congo red dye removal efficiency was 98.86 %.

Eutrophication, an aquatic problem that impacts water quality and ecosystems, can be addressed through technological developments utilizing satellite imagery to analyze the trophic status of water. This study aimed to determine the trophic status of the freshwater reservoir in different seasons using satellite imagery. Water quality data were obtained from field surveys (11 samples) during the wet and dry seasons in Cirata Reservoir (Indonesia) while the remote sensing images were obtained from the Landsat-8 OLI. Trophic status refers to Carlson's Trophic State Index consisting of two parameters named chlorophyll-A and water transparency. This study found that satellite imagery could estimate seasonal trophic information. During the wet season, the algorithms determined information about chlorophyll-A (48%) and transparency (35%). Whereas during the dry season, the algorithms successfully estimated both information at 59% and 21%, respectively. Unfortunately, the Landsat-8 OLI had limitations for estimating total phosphorus. From these two parameters, the trophic status in the Cirata Reservoir showed moderate (wet season) and mild (dry season) eutrophic. Cirata Reservoir has a higher trophic level during the wet season since it has more surface water supply with lots of pollutants.

ONTOLOGICAL AND ANTHROPOLOGICAL MEANINGS OF MYTHOPOETIC CONCEPTS OF THE ELEMENTS
Authors: Abramov Petr
Published: August 2023

The purpose of the article is to analyze matter, and more specifi cally the elements, which were understood in a similar way in diff erent cultures. The following basic qualities of the elements are revealed: water is the source of all being and vitality, earth is stability and corporality, air is space, as well as the “breathing” of the spirit, fi re is
the guiding and purifying principle. Fire, especially in its most refi ned manifestation of light, and also air act as a pair of «upper» celestial, active elements. Earth and water follow the «upper» elements and complement them. «Axis of the world» connects the earth and sky, uniting all the elements. As its manifestations, which set the vertical and center the cosmos, are the world mountain and tree, as well as fi re, such as the «center of the universe», Hestia of the Pythagoreans. Natural numbers such as 2, 3, 4 set the structure and dynamics of the development of nature and man. In mythopoetic perception, the realistic setting of everyday consciousness is inextricably woven into the holistic panpsychist symbolic picture of the world. It is concluded that the archetypal mythopoetic ideas about the elements act as a source of meaning for philosophical knowledge: for the philosophy of art, anthropology and ontology.
