Authors: Mazur Tetiana , Shchur Nataliia , Boianovskyi Serhii
Published: January 2023

Global environmental changes have caused transformations in the biology of microorganisms, especially among campylobacter, which are currently associated with food toxic infections. The means of influence of these bacteria on susceptible organisms, namely toxins, have not been finally clarified. The purpose of this study was to investigate the genetic conditionality of toxin formation in isolates of Campylobacter jejuni and determination of the degree of inhibition of the body’s protective reactions by toxic fractions of Campylobacter protein compounds. The methodology of this study was based on the polymerase chain reaction using primers to indicate the nucleotide sequences of the Campylobacter jejuni genome that encode the synthesis of toxins. Samples from 4 Campylobacter isolates were examined for the content of protein fractions according to the Lowry assay. The analysis of the electropherogram of the results of DNA amplification in a comparative aspect with the data of standard samples allowed establishing the presence of genome elements that indicate the potential ability to produce toxins in Campylobacter jejuni isolates sampled from the material under study. Toxic fractions separated from the supernatant of Campylobacter jejuni broth culture are represented by protein-carbohydrate substances. The obtained peak toxigenic fractions of the dialysate of the bacterial culture sediment contained protein within 9.5-17 μg/ml. In the dialysate of the broth culture supernatant, where 5 groups of toxigenic fractions were distinguished, their protein content ranged within 10-85 μg/ml. By reproducing the opsono-phagocytic reaction involving toxigenic fractions of Campylobacter jejuni, a sufficiently pronounced immunosuppressive effect of these complexes on the body of warm-blooded animals was established with an opsonic index of 2.6 ± 0.03. The obtained results allow clarifying the connection between toxin formation in Campylobacter jejuni and their immunosuppressive effect on the body of warm-blooded animals and humans, which in the future will positively affect the improvement of measures for the prevention and treatment of animals with this pathology

Published: January 2023

The teaching practice in technical, technological, and engineering education requires well-structured laboratories with didactic resources that provide the actors in the teaching and learning process with better interaction between the topics covered and the search for a practice. Thus, it is fundamental that lecturing institutions have teaching resources in their laboratories that the lecturers would use to improve their teaching-learning process. A teaching bench is a good option among the previous didactic models. The machine elements didactic benches allow a better explanation and application of the relationships between the various mechanical elements and related several subjects. For this reason, this work aims to build two didactic benches to assist the teaching-learning process under technical and didactic standards for teaching courses and/or related subjects of machine elements and later performance of engine bench tests to ensure its operation. The first didactic bench aims to assist in classes in relevant subjects involving machine elements. It has several components in it, and its characteristics and functionalities can be visualized. It has an electric engine for activation and a Prony brake type that measures the motor's torque and power demands. Additionally, it allows the student to visualize the correlations of the various calculations with practice, such as transmission ratio, torque, and power. The second didactic bench concerns the analysis of internal combustion or electric engines' functionalities, in which several parameters are analyzed, such as speed motor, torque, power, and fuel consumption. The engine bench has a load cell, rotation sensor, and Prony brake type initially adapted to test two engine models (electric and internal combustion). This work was developed using machine design methodology, highlighting the informational, conceptual, preliminary, and detailed design. The didactic bench tests ensured that they could be used in the teaching-learning process for engineering students. Moreover, with the construction of the small engine test bench, it is possible to evaluate internal combustion engine operating parameters, such as power, strength, rotation, and fuel consumption.

Published: January 2023

Food retailing industry has expanded commensurate to the growing requirements of a bulging world population. Initially, most retailers depended on external suppliers for most of their stock. The suppliers controlled the branding and pricing elements. This has since evolved with retailers having exponentially grown, endowing them with the ability to support their own brands.In addition to the inherent additional capability, changing business dynamics have meant that retailers have introduced additional aspects to their in-store brands. These brands which have been developed in-house have grown in scale and reach but still limited to branded stores. Food retailing has spawned lateral branded stores with respect to their food characteristics.The study has focused on evaluating the myriad factors that have sufficiently influenced consumer psychographics when choosing private store brands instead of commercial name brands. This was achieved by analyzing; general marketing strategies, effective branding, pricing and associated discounting, and general attractiveness of store brands.The condensed objective was dissected into related sub-objectives including; the marketing strategies that have been pursued by food retailers in promoting their own brands, factors that influence preference for store brands in relation to pricing, discounts, psychographic dynamics, existence of promotion thresholds and their overall influence on purchasing habits.Research was undertaken using qualitative methods by surveying the emerging trends that have supported the growth of store brands. Price comparisons were made from empirical data collected from several outlets while the survey was conducted on consumer responses to pricing and discounting. The resultant data was evaluated and represented in tables and charts to support the primary objective of the research.

The Covid-19 pandemic brought several challenges to the educational system with regard to the continuity of classes in the context of an Emergency Remote Education (ERE). Among these challenges, we highlight the intensification of disinterest and low participation of students in chemistry classes and the insufficiency of didactic proposals that work with School Inclusion (SI), with a focus on accessibility for the deaf. The ERE model lasted 2 (two) years, after this period, teachers had to face a new change in the school scenario: Post-pandemic Face-to-Face Teaching (post-pandemic FFT). Thus, with the return to classes, the challenges mentioned were accentuated, bringing again the demand for the adoption of new educational strategies. Within this context, this article is justified in the development of a pedagogical intervention focused on the inclusive teaching of Chemistry in the post-pandemic FFE, linked to the principles of Green Chemistry (GC) and the 6th Sustainable Development Goal (SDG). This action aimed at the elaboration of accessible didactic materials, together with the application of an experimental, contextualized, and sustainable practical class called: Batch Adsorption with activated charcoal from the endocarp of the coconut (biodegradable adsorbent). The results of the research showed that the adoption of the contextualization methodology, concomitantly with the development of the practical activity, pointed to an improvement in the teaching of Chemistry in the post-pandemic face-to-face model. Therefore, sustainable experimentation effectively contributed to the learning process and a more critical look at the socio-environmental issues discussed.
Relationship between attendance and academic performance among student-athletes in Obuasi municipality, Ghana
Authors: Apaak Daniel , Yawson Joseph Anthony
Published: January 2023

Participation in sports is a topic that has gained considerable attention over the years.  While many scholars argue that sports participation results in high academic output among student-athletes, others contended that it decreases academic performance. There is another school of thought that has established that participation in sports promote absenteeism. Despite these discussions, there is a gap in the literature on the relationship between absenteeism and academic performance among student-athletes particularly in a developing country like Ghana. Therefore, this study investigated the relationship between absenteeism and academic performance among 203 student-athletes in two public senior high schools in the Obuasi Municipality of Ghana. A census was employed to gather data from all the student-athletes who were in form three and form two. A generated form that solicits student-athletes end of semester results in the core subjects English, Mathematics, Integrated Science, and Social studies, and attendance for two semesters was the main instrument used to gather the data. Data was analysed using percentages and correlation. The results showed that student-athletes attendance to classes was high and their academic performance was also good. The results further revealed that the academic performance of the student-athletes is linked to their class attendance. It is recommended that the management of senior high schools and other stakeholders within the Obuasi Municipality should find ways of encouraging students to participate in school sports and attend classes regularly since that might improve their academic performance.

Published: January 2023

Due to the Covid-19 pandemic, practically all colleges and universities in the United States shifted their conventional instructional mode of the in-person face-to-face classroom teaching to the virtual online instruction in the middle of the spring 2020 semester. While online-only institutions, majority of which are for-profit, eagerly promoted their online education, all of the conventional colleges and universities struggled to provide the necessary training for the instructional faculty and to assure students and their parents that the quality of their college education would not be compromised. In this research, we explored the impact of such quickly adopted online instruction as an inevitable alternative during the pandemic on the student learning as the pandemic placed them in a natural quasi field experimental condition. We found a significant difference in the student learning outcome recorded in the semester grade between the two periods: the difference is particularly prominent in non-participation or withdrawal from the learning process as reported in the grades of fails and withdrawals. Implications of the study for college and university enrollment and the compelling need for further study are discussed.
Lust and Loss in Ravenhill’s Shopping and F****ing & Kane’s Blasted: Troubling Trends in a New Culture
Authors: Ngezem Eugene
Published: January 2023

As the modern world hangs on a string of utter moral collapse, several writers unleash moral restraints, thus bringing immorality to the market square to consumers who seem to yearn for the collapse of moral walls in their world. Hearkening to such cravings, Mark Ravenhill’s provocative title and play, Shopping and Fucking (1996), and Sarah Kane’s flaming play, Blasted (1995), present morally bankrupt characters clothed in the garments of modern humanity. Glued to wild and recurrent sexual habits, suggesting, as it were, the unceasing erosion of human dignity, these characters cling, with menacing sternness, to sex at all times and in all lieu. Like burning candles that consume their own heights, chronic sexual drives and activities in the works of the foregoing playwrights depict our world and diminish the statue of humanity. Set in an economically dejected and drug-redden East End of London, Shopping and F****ing serves as a canopy under which sits rancorous, impulsive, and rampant sex and drugs with the attendant loss they create. In a similar vein, Sarah Kane’s Blasted, set in a war-torn city, which duplicate the ruins of our societies, depicts depraved characters who have sex at whim and with impunity.

Published: January 2023

The machine control has always been a task, carried out exclusively by people who do not work directly on the production lines, so people directly involved in production do not need to worry about the materials needed for their work, and with this model there was difficulty when product supply. Therefore, the objective of this research was to identify benefits and results in the application of the Kanban system in a marine engine maintenance company, in the warehouse sector, added to the selection of literature that conceptualized the mechanism of the system; the identification of the process, from the organization of maintenance parts, as a way to facilitate the maintenance of marine engines. The company studied, founded in 2014, headquartered in the city of Manaus/AM, specializes in marine engine maintenance, with machinery as its main sector. The company has vacancies ranging from 11 to 50 employees annually, according to demands and times of the year. The methodology addressed is of a mixed nature, being part bibliographical in order to select works for the basis and better understanding of the subject, and part case study, since the maritime maintenance company will be the focus of this article. The kanban system determines the quantity of supply so that bottlenecks do not occur with regard to the company's production. Regarding the updating of the table, every day you should check which are the stocks with the highest degree of demand, indicated by the color red, being possible and necessary to pass on to the replacement sector, the missing products. the control system was installed by means of plates that indicated the quantity of parts they had and with that, it could be predicted which parts were priorities in reallocation in the stock, replacing mainly products and fundamental parts for the continuity of the maintenance. After applying this process, it was possible to easily identify the needs and speed up the notes of the company's technical staff with the supply sector (purchases), as well as to avoid the constant lack of “priority” parts in the maintenance process. The performance of the kanban production system applied to the marine engine company was concluded, since the nameplates of the missing parts became much more visible, optimizing the replacement process of pending parts. This production technique presented in the study is of great importance in today's world, as it focuses on the quality of the production process and the quality of finished products offered to the market, making the company that has this system solidify and can remain competitive.

Published: January 2023

In recent decades, technological advances and increased urbanization have instigated remarkable growth in the construction industry, and consequently an increase in environmental impacts both in obtaining raw materials and in the disposal of construction waste. Some studies are being carried out in Brazil for the application of natural fibers as a reinforcing element to produce concrete. According to these facts, the focus of this work is to comparatively evaluate the mechanical strength of commercial concrete with concrete produced with piaçava fiber sludge. Attalea funifera Martius, commonly known as piaçavas, is a solitary, thornless, erect, caulescent palm from the Aracaceae family. It reaches an average height of 8 to 15 meters with a stem diameter of 20 to 25 cm, having 8 to 10 leaves, each 9 meters long. Ten specimens were produced to carry out compression tests. Water, common Portland cement (CP I), sand, gravel and piassava obtained in the municipality of Barcelos-AM were used in the preparation. After curing the specimens, compression tests were carried out until the specimens ruptured. We also observed that the most resistant specimens were those produced with the addition of crushed stone, since the resistance of the specimen with crushed stone was approximately 22 MPa against 19 MPa of piaçava concrete. The main conclusions verified is that with the use of piaçava in the concrete mixture there is a drop in mechanical resistance, despite being a material that presents resistance to cracks, it does not have the same capacity as concrete with gravel as a coarse aggregate.
Results of Radionuclide Vector Verification to Characterize Solid Radwaste of Chornobyl Nuclear Power Plant Sent for Burial
Authors:   Institute for Safety Problems of Nuclear Power Plants, NAS of Ukraine, Mykhailov O. V.
Published: January 2023

The first radionuclide vector (RV) for characterization of operational solid radioactive wastes (SRW) of Chornobyl Nuclear Power Plant (ChNPP) according to the IAEA methodology was established in 2018 and consisted of a set of scaling factors (SF), which have never been refined and updated, as it is recommended to be done from time to time. In this work, verification algorithm of previously established SF values, provided for by RV setting technique, was tested, and their values were updated with taking into account the implementation of a new approach for sorting ChNPP SRW into the streams. It was established that for such nuclides as 90Sr, 94Nb and 241Am, geometric mean values of SF or correlation function (CF) established on the basis of regression analysis of logarithms of nuclide content, can be used. For the other radionuclides (14С, 3Н and 235, 238U), whose activity levels were higher than the minimum detectable activity (MDA), arithmetic mean values of SF only can be used. For uranium isotopes 235, 238U, a high degree of correlation between their content is observed in all SRW materials, regardless of whether they belong to combustible or non-combustible operational waste of the ChNPP. According to the test results (testing for significance of difference under the null hypothesis) using the Student’s t-statistics, it was established that the same SF values can be applied to the waste temporarily stored in the eastern and western compartments of the ChNPP SRW repository. The waste should be separated into non-combustible and combustible materials only. This follows from the fact that combustible solid waste, if they are to be burned as it is planned, must be re-characterized using the SF value already determined for ash and by a different technique. However, until these wastes are burned, the obtained data allow estimating the expected levels of nuclide content in their ash residue.

Diets enriched in plant-based foods are associated with the maintenance of a good well-being and with the prevention of many non-communicable diseases. The health effects of fruits and vegetables consumption are mainly due to the presence of micronutrients, including vitamins and minerals, and polyphenols, plant secondary metabolites. One of the most important classes of phenolic compounds are anthocyanins, that confer the typical purple-red color to many foods, such as berries, peaches, plums, red onions, purple corn, eggplants, as well as purple carrots, sweet potatoes and red cabbages, among others. This commentary aims to briefly highlight the progress made by science in the last years, focusing on some unexpected aspects related with anthocyanins, such as their bioavailability, their health effects and their relationship with gut microbiota.
Spinal Cord Stimulation for Gait Disorders in Parkinson’s Disease
Authors: Opova Karolina , Limousin Patricia , Akram Harith
Published: January 2023

Background:

Spinal cord stimulation (SCS) is a therapeutic procedure widely used in the management of refractory chronic pain. Evidence from case reports and small descriptive studies has emerged suggesting a role for SCS in patients with gait dysfunction, such as freezing of gait (FoG) and postural imbalance. These are severely debilitating symptoms of advanced Parkinson’s disease (PD).

Objective:

To establish the current evidence base for the potential application of SCS on gait and balance dysfunction in PD patients.

Methods:

Three online databases were screened for relevant manuscripts. Two separate searches and four different search strategies were applied to yield relevant results. The main parameters of interest were postural and gait symptoms; secondary outcomes were Quality of Life (QoL) and adverse effects.

Results:

Nineteen studies fulfilled the inclusion criteria. Motor improvements using section III of the Unified Parkinson’s Disease Rating Score (UPDRS-III) were available in 13 studies. Measurements to assess FoG reported the following improvements: FoG questionnaires (in 1/19 studies); generalized freezing parameters (2); and walkway/wireless accelerometer measurements (2). Parameters of postural imbalance and falling improved as follows: BBS (1); posture sagittal vertical axis (1); and generalized data on postural instability (8). Two studies reported on adverse effects. QoL was shown to improve as follows: EQ-5D (2); ADL (1); SF-36 (1); BDI-II (1); PDQ-8 (1); HDRS (1); and VAS (5).

Conclusion:

SCS may have a therapeutic potential in advanced PD patients suffering from postural and gait-related symptoms. The existing evidence suggests that SCS positively affects patients’ QoL with an acceptable safety profile in this patient population.
Estimation of financial contagion in agricultural commodity futures markets using correlation analysis
Authors: Ovcharov Anton
Published: January 2023

Abstract. In the context of financial instability affecting all sectors of the modern economy, an important direction is the study of the effects of contagion – the transmission of instability through different channels between countries, industries and individual economic assets. The purpose of the article was to analyze the comovement of prices for agricultural goods through the study of the relationships of profitability of commodity futures and to obtain on this basis estimates of the scale and direction of financial contagion in food markets. Methods. Advanced methods of correlation analysis were used in the article: correlation coefficients adjusted for heteroscedasticity were determined; the hypothesis of the presence of infection was tested using Forbes – Rigobon test statistics. In addition, based on the calculation of the volatility of commodity futures using the rolling standard deviation method, the time periods necessary to detect infection were distinguished. Scientific novelty. For the first time in Russian practice, an analysis of the effects of financial contagion on the agricultural sector was carried out; quantitative estimates of the scale and direction of infection spreading through internal channels of exchange trade in food products were obtained. Results. A study of the dynamics of prices for some futures for 2003–2022 made it possible to identify periods of increased volatility of commodity markets. It took the highest values in 2008–2009 and 2020–2022 – during these periods, volatility shocks led to the spread of contagion in the futures markets of agricultural commodities. However, the scale of infection was uneven. In the crisis of 2008–2009, 51.8 % of cases of infection were detected, while in 2020–2022 this share was 23.2 %. As for the transmission of infection in paired bundles of the type “commodity-source  commodity-recipient”, most often the sources and recipients were cocoa, coffee and sugar, the least often – soybean meal and lean hogs. In addition, the analysis of paired correlations made it possible to conclude that the predominance of bidirectional contagion.
