Authors: N Gyimah
Published: June 2023

Schools across the globe were shut down at the peak of the COVID-19 with the reason to contain the spread of the virus and that universities were not exceptional as students walked home without any proper strategic plans towards the educational journey as the future of the pandemic was unknown. Universities around the globe started to embrace the future by moving from real classroom teaching to a more digital classroom where students were taught by lecturers online. It was for that reason this study was conducted to evaluate university students’ journey about the use of Learning Management System, Zoom and Google meet to navigate in the digital classroom during the closure of schools at the peak of COVID-19. The study used both primary and secondary data. A questionnaire was developed and administered to obtain the primary data. However, the study selected 10 public universities in Ghana and engaged 500 students as the research participants. Again, convenience and simple random sampling techniques were used to select universities and students respectively. It was confirmed by students that universities shifted from classroom teaching to virtual teaching and that this confirmation was substantiated by students to reveal that Learning Management System was greatly used to conduct virtual teaching that was followed by Zoom and lastly Google meet. In addition, it was found that some students were not digitally literate and this actuated difficulty to excel in the digital classroom created by the universities. It was recommended that universities should factor basic computing into the programme-based courses so that students could become digitally literate and fully prepared for the future.
Possibilities of Viral Immune Evasion Exemplified by Human Papilloma Virus in HIV-Infected People
Authors: KE Boeva
Published: June 2023

Immune surveillance is of great significance for development of papillomavirus infections, as it has an impact on the disease course and its transformation into neoplasias. Immune response in infection of HIV patients with human papillomavirus deserves particular attention. Numerous studies suggest modification of immune response by the viruses in monoinfections (human immunodeficiency virus, human papillomavirus) and in combined infections. At present, numerous possible viral evasion mechanisms of innate and adaptive immunity factors are known. Despite a large body of accumulated knowledge on the HIV and papillomavirus infection course, early diagnosis and timely treatment of coinfected patients are hampered, which adversely affects their prognosis. There is still a need for expanding the techniques for early diagnosis of papillomavirus infection in HIV-infected individuals and searching for effective treatment methods.
Cost-Utility of Venovenous Ecmo Associated with Protective Mechanical Ventilation in the Treatment of Patients with Acute Respiratory Distress Syndrome
Authors: Marta Cristiano Bertolossi
Published: June 2023

Introduction: with the emergence of COVID-19 in the world, there was a race against time in the search for studies and scientific information that validated the most appropriate treatment. As a result, when caring for patients with the disease who developed ARDS and progressed to a severe condition with hospitalization in the ICU, the need for scientific evidence to guide care for these patients was even greater. Speculation about the effectiveness of using ECMO for these patients began to emerge, and with it, the need for scientific studies that would show the costs and benefits of acquiring this technology in the SUS. The dissertation that is intended to be defended is whether the use of VV ECMO associated with protective mechanical ventilation in patients with ARDS is more cost-effective compared to exclusive protective mechanical ventilation. General Objective: to analyze the cost-effectiveness of veno-venous ECMO in the treatment of patients with COVID-19 who evolve with severe Acute Respiratory Failure. Specific Objectives: review the scientific literature to summarize the best scientific evidence available on the safety and efficacy of using exclusive mechanical ventilation and venovenous ECMO in patients with acute respiratory failure, and estimate the costs associated with mechanical ventilation and the use of veno-venous ECMO. Method: Rapid systematic review for a complete health economic assessment based on a Markov model to estimate the incremental cost-effectiveness of using venovenous ECMO associated with protective mechanical ventilation in the treatment of patients with ARDS due to COVID-19. Results: Based on the estimated costs in each of the base case scenarios and the probabilities of the clinical effects resulting from the interventions, the study showed that the ECMO + protective IMV intervention offers around 0.295 AAQA compared to 0.2015 AAQA offered by the exclusive protective VMI. The incremental cost of ECMO + protective IMV is BRL 12,519.94 for 0.397 effectiveness compared to 0.215 exclusive protective IMV (incremental effectiveness of 0.182). For each qualityadjusted year of life gained, the amount of R$ 68,902.92 would have to be disbursed. Conclusion: the results showed that both veno-venous ECMO associated with protective mechanical ventilation and exclusive protective mechanical ventilation can be cost-effective alternatives for the treatment of patients with ARDS due to COVID-19 in the SUS, depending on the willingness to pay. However, in terms of effectiveness, ECMO was the most effective alternative, but with the highest cost increase.

Published: June 2023

Inductance measurements is important for all branches of technology related to the application of electricity: energy and electronics, radio and television, transport and communication, and scientific research. Electromechanical devices and electronic components can be characterized using impedance measurements to identify the parameters of their equivalent electrical model. New inductance measurement methods are being developed in specific fields of activity. Manufacturers of standards and measuring instruments of inductance develop special handbooks outlining various methods of inductance measurement. The State Primary Standard of Ukraine for inductance and loss angle tangent reproduces and transmits a unit of inductance in the range from 1∙10-6 H to 10 H at a frequency of 1 kHz. It is keeping in the SE “Ukrmetrteststandard” and participated in several comparisons of national standards within the framework of the activities of regional metrological organizations. The calibration and measurement capabilities of inductance measurement of national laboratories of different countries were studied to analyze and compare the capabilities of the national standard with the standards of other countries. Long-term instability studies of inductance measures of 1 mH, 10 mH and 100 mH, which are part of the national standard unit of inductance, have been conducted. The research period covered from 2009 to 2022. It was established that the drift lines of the specified inductance measures can be described using linear approximations. The rationale for choosing inductance measures of 10 mH and 100 mH for their use as transmission standards in the calibration of standards, which were organized and conducted by SE “Ukrmetrteststandard” as their pilot laboratory, is given.

Abstrak. Pandemi Covid-19 telah mengubah banyak aspek kehidupan kita, cara komunikasi, belajar  dan termasuk dalam melakukan transaksi. Hal ini memaksa banyak perusahaan beralih dari sistem pencatatan transaksi manual ke sistem pencatatan transaksi dengan menggunakan teknologi informasi (TI). Penggunaan TI dalam bertransaksi sebenarnya sudah ada sejak lama, namun pandemi ini mengakibatkan adanya peningkatan yang signifikan dalam penggunaan TI dalam berbisnis. Sistem transaksi yang terkomputerisasi, sistem yang dapat diakses secara online dan memiliki data dalam cloud semakin populer karena memungkinkan orang untuk melakukan pencatatan dan pengawasan dari jarak jauh tanpa harus melakukannya secara manual. Penggunan TI dalam proses bisnis akan sangat membantu dalam analisa data, karena data tersimpan dan terolah dengan baik sehingga dapat memberikan masukan atau pertimbangan untuk langkah bisnis berikutnya. Toko XYZ belum memiliki pencatatan yang sistematis, sehingga penjualan hanya dicatat seadanya saja dan tidak adanya fungsi laporan membuat pemilik kesulitan untuk melacak jumlah penjualan dan memutuskan langkah dalam bisnis. Penelitian ini menghasilkan sebuah aplikasi berbasis web yang membantu toko XYZ dalam melakukan pencatatan penjualan dan memberikan laporan penjualan untuk pemilik. Laporan penjualan dapat diberikan secara periodik sehingga membantu pemilik untuk dapat memutuskan langkah untuk melanjutakan proses bisnisnya.
 
Abstract. The Covid-19 pandemic has changed many aspects of our lives, the way we communicate, learn and make transactions. This has forced many companies to switch from manual transaction recording systems to transaction recording systems using information technology (IT). The use of IT in transactions has actually been around for a long time, but this pandemic has resulted in a significant increase in the use of IT in business. Computerized transaction systems, systems that can be accessed online and have data in the cloud are increasingly popular because they allow people to record and monitor remotely without having to do it manually. The use of IT in business processes will greatly assist in analyzing data, because the data is stored and processed properly so that it can provide input or consideration for the next business step. Store XYZ does not yet have systematic records, so sales only record them and the absence of a report function makes it difficult for the owner to track the number of sales and decide on steps in the business. This research produces a web-based application that helps XYZ stores record sales and provide sales reports to owners. Sales reports can be provided periodically so that it helps the owner to be able to decide on steps to continue his business process.

Published: June 2023

Monitoring the use of electrical energy is generally done by looking at the kWh meter on the installed panel. Power consumption can also be done by measuring directly on the network or electrical load using a Watt meter. Monitoring of 3-phase electrical energy needs to be monitored, especially to find out the amount of energy used in each phase, and on the other hand, it needs to be controlled so that energy use can be controlled, both for each phase or 3 phases. This study aims to design an IoT-based 3-phase electrical energy monitoring and control application. Data on the flow of electrical energy flowing to the load can be monitored from the android, and vice versa can be controlled by disconnecting and reconnecting the energy flow. The PZEM004T component is used as an energy flow sensor, buttons on the application function to disconnect and connect energy flows, and LCD12C and smartphones are used as monitoring devices. The Blynk application is equipped with several switch buttons used to control energy use, along with electronic device control. The data read by the tool can be retrieved and stored in Blynk using the superchart widget so that the operator can see previous history record data sent to emails that have been linked to the Blynk application according to the operator's wishes. The results of the research show that the research tool can display voltage, current, power, energy, and frequency data that can be displayed on a smartphone and LCD. The average error of the mains power compared to the reference meter is 0.02%.

Implementation of the Right to Choose a Cultural System by Islamic States: a Comparative Analysis
Authors: Pchelintseva V. V.
Published: June 2023

Introduction. The right to choose the state’s cultural system derives from the principle of noninterference in the matters within its domestic jurisdiction. Although the necessity to precise the content of the main principles of international law has been outlined in the Russian international law doctrine, hardly any research focusing on the right to choose cultural system can be found. The research on international law position of the Organization of Islamic Cooperation and its Member States concerning the right to choose the state’s cultural system is lacking despite the fact that historical, cultural and religious particularities of the Member States of the OIC affect the scope of their obligations under international law.

Materials and Methods. The research aims to discover the particularities of the exercise of the right to choose cultural system by the Member States of the OIC and their impact on the qualification of matters within domestic jurisdiction of these states. The research includes historical and systemic legal analysis of the principles and norms of general international law concerning the right to choose the state’s cultural system and their application in OIC acts and constitutional law of OIC Member States on the example of the Arab Republic of Egypt, Islamic Republic of Iran, Kingdom of Saudi Arabia and Republic of Iraq.

Results. The sovereign and inalienable right to choose the state’s economic, political, social and cultural system was enshrined in universal, regional and bilateral international law acts in the result of codification and progressive development of international law norms in the second half of XXth century. The exercise of this right is limited by the state’s international law obligations. Including provisions on the state’s historical, cultural and religious particularities in the state’s basic law should be considered as a form of exercising its right to choose cultural system.

Discussion and Conclusions. If historical, cultural and religious particularities of a state constitute the basis of its state and social system, the legal regulation of these particularities should be considered the matter of its domestic jurisdiction. Thus, such particularities may not be regulated by international law. OIC acts enshrine the limitation of the exercise of the right to choose the state’s cultural system as well as the Member States’ position as regards cases when interference in the exercise of this right is not permissible. The attachment of some OIC Member States to the principles of Islamic Sharia should be considered not only as their historical, cultural and religious particularity but also as a basis of their state and social system, which falls within their domestic jurisdiction.

O transtorno de déficit de atenção com hiperatividade, mais conhecido como TDAH, é uma doença mental que possui como principais sintomas dificuldade para se concentrar, hiperatividade e comportamento impulsivo.

Na vida adulta, esta doença pode trazer uma série de consequências significativas e perdas no lado profissional e nas relações interpessoais. Mesmo acometendo de 3 a 5% das pessoas em todo o mundo, o TDAH ainda é cercado de muito preconceito e estigma. Muitos ainda não o consideram uma doença e acreditam que o transtorno não existe, o que dificulta a busca por tratamento médico, muitas vezes por falta de informação científica.
Novel Quasi-One-Dimensional Analysis of a Choked Transonic Reacting Flow with Finite-Rate Chemistry
Authors: Cha Seongik , Young Kim Nam , Do Hyungrok , Kang Kyungrae
Published: June 2023

A numerically accurate method for solving quasi-one-dimensional transonic flow with a system of ordinary differential equations (ODEs) has been developed to estimate the performance of a high-speed propulsion system. Specifically, ramjet engines are thermally choked in the combustor region. for which the solution processes undergo a mathematical singularity problem. This singularity incurs various numerical difficulties because the derivatives are indeterminate at the sonic condition and the solution cannot march in the streamwise direction, requiring special numerical treatment. To overcome this issue, two solution processes are augmented in the ODE system: coordinate transform, and solution extrapolation from the equivalent subsonic system. An additional variable is defined to convert the spatial coordinate into a dependent variable that characterizes the transonic flow only by the solution curve passing through the critical point. After the transformation, solution variables are extrapolated from the subsonic solutions obtained with a predicted critical (sonic) condition via a forward iterative shooting method such that the flow properties are smoothly varying both upstream and downstream of the critical point. As a result, there is a good agreement in the predicted critical point with the theoretical location. Moreover, the new method successfully yields the transonic solution without any abrupt or discontinuous changes in flow properties including species fractions, which is almost impossible with existing methods.

The Sakhalin taimen, Parahucho perryi, occurs along the sea coast of Primorsky Krai, but to date, self-reproducing populations have only been noted in the central and northern coastal regions between the Kievka R. in the south and the Samarga R. in the north. The Pacifi c Branch of VNIRO (TINRO) surveyed the Sakhalin taimen populations during the fi eld work in the north-east of Primorsky Krai in 2018–2022. New information about the current population status of the Sakhalin taimen has been obtained. On the basis of original and compiled data, a general increase in the abundance of the species in the rivers Edinka and Samarga including surrounding marine water areas was revealed. The presence of all size groups from underyearlings to large individuals weighing more than 20 kg was noted. These facts suggest that the living conditions and natural reproduction of the Sakhalin taimen in the area favor the growth of its populations. Since the situation in the southern regions is worse, an action plan has been proposed for conservation and restoration of the species populations in Primorsky Krai, the main point of which is the need to conduct a comprehensive study of the state of Sakhalin taimen populations.

Published: June 2023

A number of recent reports have implicated ultrafast (femtosecond-picosecond) timescale motions in enzymatic activity, but relatively few experimental studies have addressed complications arising from spatially-distributed disorder, multiple substrate binding modes, or the influence of hydration dynamics on solvent-exposed active sites. Here we use ultrafast two-dimensional infrared (2D IR) spectroscopy and covalently-tethered substrate analogs to examine dynamical properties of the Pyrococcus horikoshii ene-reductase (PhENR) active site in two defined binding configurations. Frequency-fluctuation correlation functions of aryl-nitrile analogs reveal an end-to-end tradeoff between fast (sub-ps) and slow (>5 ps) motions. Lineshape and quantum beat analyses of Fermi resonant aryl-azide analogs demonstrate that this is an intrinsic property of the water-exposed active site. This study indicates that elements of polar pre-organization are maintained at the interface and suggests several plausible factors leading to state-selective rate enhancement and promiscuity in PhENR.

Published: June 2023

Synthetic anion receptors are increasingly explored for the transport of anions across lipid membranes because of their potential therapeutic applications. A considerable amount of research focuses on the transport of chloride whereas the transmembrane transport of inorganic phosphate has not been reported to date, despite the biological relevance of this anion. Here we present a calix[4]pyrrole with a bisurea strap that functions as a receptor and transporter for H2PO4–, relying on the formation of 8 hydrogen bonds and efficient encapsulation of the anion. Using a phosphate-sensitive lanthanide probe and 31P NMR spectroscopy, we demonstrate that this receptor can transport phosphate into vesicles by H2PO4−/Cl− antiport, H2PO4− uniport, and Cs+/H2PO4− sym-port mechanisms. This first example of inorganic phosphate transport by a neutral receptor opens perspectives for the future devel-opment of transporters for various biological phosphates.

Published: June 2023

Although the Global Navigation Satellite System provides an increased precision in instrument approaches, it is vulnerable to various signal interferences causing either decreased position accuracy or a complete loss of GNSS signal reception. One of the major threats to a GNSS receiver is the intentional interference known as jamming. Incoming airplanes can be seriously endangered by such signal loss. This bachelor’s thesis addresses the detection and classification of possible unintentional and intentional interference and spoofing attacks on airplanes in proximity to the airdrome Žilina. Besides that, other systems which show sufficient reliability are compared. Additionally, critical parts of RNP approach chart map are evaluated. Finally, a device called HackRF ONE is selected to be put in aerodrome proximity for detection of possible GNSS interference. Using this software defined radio as unmanned aerial vehicle alarm and protection system is another suggested possibility.

With the growing demand for electric vehicles (EVs), the importance of efficient thermal management systems has significantly increased. These systems play a crucial role in maintaining optimal performance and prolonging the lifespan of critical components, particularly electric motors. However, traditional cooling methods often struggle to meet the high heat dissipation requirements of EV motors, resulting in reduced overall efficiency and reliability. To address this issue, the integration of nano fluids as a cooling medium has emerged as a promising solution. Nano fluids, which are engineered colloidal suspensions, consist of a base fluid (such as water or oil) and nanoparticles with sizes ranging from 1 to 100 nanometers. Through the dispersion of nanoparticles within the base fluid, nano fluids possess unique thermal properties that significantly enhance heat transfer efficiency compared to conventional fluids. This abstract provides an overview of the application of nano fluids in E-vehicle motor cooling, emphasizing their potential benefits, challenges, and future prospects.

Authors: Gorshkov Y.G.
Published: June 2023

The article presents the results of research on the assessment of human emotional tension by a speech signal using the developed technology of multilevel wavelet analysis. The disadvantages of polygraph systems during psychophysiological inspections of personnel are given. The data obtained by domestic and foreign experts allow us to make a confident conclusion that the characteristics of a person's oral speech correlate with changes in their condition. The characteristics of the hardware and software complex «Icar Lab» (Russia) in assessing the emotional state of the speaker, as well as the computer voice stress analyzer CVSA (USA) are considered. A new contactless technology is proposed for assessing the level of emotional tension of a person using stress biomarkers obtained on the tonal parts of speech. The WaveView-VSA program for obtaining high-precision time-frequency characteristics of a speech signal has been developed. The possibilities of the developed program for visualizing the level of emotional tension are presented. A database of audio recordings of 6th-year students who are in conditions with increased emotional stress during the exam and the defense of the graduation project has been formed and processed. The research conducted by the Scientific and Educational Medical and Technological Center of the Bauman Moscow State Technical University showed the fundamental possibility of obtaining real-time acoustocardiography data and the level of emotional tension in the examined students during express cardiodiagnostics. The developed technology provides biomarkers of stress based on a speech signal lasting several seconds.

As initial data, photographs of buildings and structures obtained using a camera of an unmanned aerial vehicle and their drawings were used. When building a 3D model, the capabilities of Autodesk AutoCAD and Autodesk Revit were used. When building a 2D information model, a combination of a 3D model and a photograph of the object was used. The resulting 3D and 2D models are included in the structure of the flight chart as part of an applied digital platform in an automated decision-making system for expert assessment of the technical condition compliance of a hazardous production facility with regulatory requirements. Violation of regulatory requirements entails the occurrence of emergencies and incidents at an industrial enterprise. Visualization elements allow increasing the reliability of information entering the database of expert information.

Indonesia telah mengalami banyak kemajuan pada bidang konstruksi dengan adanya dukungan kebijakan oleh pemerintah khususnya bidang konstruksi sebagai perwujudan transformasi ekonomi menuju Indonesia maju tahun 2045. Untuk menuju Indonesia maju pada bidang konstruksi salah satunya adalah pembangunan bandara Internasional Dhoho di Kabupaten Kediri. Salah satu pembangunan gedung di bandara Internasional Dhoho Kediri adalah air traffic control tower. Fungsi dari air traffic control tower adalah sebagai pengatur lalu lintas pesawat dengan batasan wilayah yang luas, oleh sebab itu pembangunan air traffic control tower membutuhkan peran alat berat berupa tower crane sebagai mobilisasi material. Metode yang dipergunakan pada penelitian ini adalah observasi di lapangan. Dari hasil observasi di lapangan selama 10 hari, material yang diangkat oleh tower crane antara lain adalah rangka baja, scaffolding, bata ringan, bucket concrete, besi wire mesh, keramik, besi ulir, besi holo, dan besi UNP. Material dominan yang diangkat oleh tower crane berdasarkan volume material adalah besi ulir 8D dengan jumlah total volume materialnya sebesar 30105,45 Kg. Berdasarkan hasil tersebut dapat diketahui produktivitas tower crane dalam pengoperasiannya pada pembangunan air traffic control tower selama 10 hari di bandara internasional Dhoho Kediri bahwasannya tower crane dapat mengangkat berbagai jenis material dengan berat dan jenis yang berbeda-beda.

The evaluation of the heavy metals remediation potential and characterization of biosurfactant produced by Aeromonas hydrophilia strain S62A isolated from water and sediment samples of Imo River, Nigeria was studied. In this study, 12 bacterial isolates were isolated from contaminated water and sediment samples using spread plate technique and primarily screened for biosurfactant production using emulsification index, oil displacement and surface tension tests. Secondary biosurfactant production was carried out in a modified mineral salt medium under optimized conditions for 5 days and the produced biosurfactant was characterized and evaluated for its heavy metals removal efficiencies using standard analytical procedures. The result showed that the bacterial strain identified as Aeromonas hydrophilia S62A out of the 12 isolate strains had the highest and lowest values of 66.66 %, 23.76 cm and 90 mN/m for emulsification index, oil displacement and surface tension tests, respectively. The purified biosurfactant was found to be glycophospholipid as confirmed by the gas chromatographic (GC) and Fourier Transformed Infra-Red Spectroscopic (FTIR) profiles with 5 mg/mL critical micelles concentration (CMC). Statistically, significant differences (P < 0.05) were detected among the means of all surfactant CMC treatment in comparison to their untreated controls with 2 × CMC lead having the highest (98.92 %) and control (water) having the lowest (2.09 %) heavy metals removal efficiencies. Therefore, the present study has produced glycophospholipid biosurfactant with unique structural and chemical features and composition and could be exploited in environmental remediation of heavy metals contaminated ecosystems.
