Authors: Povstyanoy V. M. , Yuyrova T. A. , Retchitskiy A. N. , Krysko A. A.
Published: August 2021

It has been known that derivatives of dihydropyrimidine and xanthine possess the physiological activity of the wide spectrum of action. The combination of the specified heterocyclic fragments within one molecule can lead to the increase of its known types of biological activity as well as to the discovery of novel types of activity. We have previously reported the synthesis of intermediates, which consist of functionalized dihydropyrimidines, connected via a methylene bridge with the halogen substituted derivatives of the ophylline, 3-methylxanthine and imidazole. It was also observed that these compounds would react with N‑nucleophiles with the formation of various branched and cyclic products. The aim of this work was to determine the optimal conditions for obtaining heterocyclic products as a result of conjugation of bromomethyldihydropyrimidine and hypoxanthine at the positions C6 and C1 via a methylene bridge. It is important to note, that the latter can be widely modified by using structurally diverse aromatic aldehydes during the synthesis of dihydropyrimidine core by using Biginelli reaction, which explains structural diversity of the reaction products. After having tried various reaction conditions, we have concluded that the optimal method for obtaining the products entailed keeping equimolar ratios of bromomethyl substituted dihydropyrimidines and 1-potassium‑2-chloro‑7-methylhypoxanthine in dry ethanol for 4 hours. The ester group at the C5 of dihydropyrimidine ring and a chlorine leaving group at C2 of hypoxanthine fragments of the molecule allow to consider these structures as pro missing synthons for farther synthesis of condensed pyrimidine and xanthine systems. The structures of novel compounds have been confirmed with the methods such as HPLC/MS, 1H, and 13C NMR spectroscopy.

The equilibria processes in aqueous solutions of CrO42– – H+ – H2O and Cr2O72– – OH– – H2O systems were studied by pH‑potentiometric titration, mathematical modeling and UV–Vis. spectroscopy. It was established that in the CrO42– – H+ – H2O systems with acidity ZН = ν(H+)/ν(Cr(VI)) = 0–2.5 the processes of dichromate and hydrochromate anion formation and hydrolytic conversion of dichromate to hydrochromate take place, for which the logarithms of the equilibrium concentration constants were calculated by the quasi-Newton method (CLINP 2.1 software; 95 % confidence probability). The calculated values of the logarithms of the concentration equilibrium constants lgKC reliably agree with the literature data. The calculated lgKC were used to build of chromium(VI) anions distribution diagrams depending on ZH, and ZOH in solutions. For the first time, by the Pitzer method the thermodynamic equilibria constants of hydrochromate HCrO4– (lgK10 = 6,94), the dichromate anion Cr2O72– (lgK20 = 15,49) formation processes from the CrO4 2– and H+ ions, and the logarithm of equilibrium constant of the interconversion of the dichromate anion to the hydrochromate anion (lgK30 = –1,61) were calculated. Mathematical modeling and UV–Vis. spectroscopy show that the composition of anions in Cr2O72– – OH– – H2O solutions with alkality ZOH = ν(OH–)/ν(Cr(VI)) = 0–2.5 is identical to CrO42– – H+ – H2O systems. It is established that the experimental dependencies pH = f(Z) for the Cr2O72– – OH– – H2O system can be reliably reproduced by hydrolysis reactions of dichromate anion to hydrochromate anion and by subsequent neutralization to chromate anion with equilibrium constants calculated for processes in CrO42– – H+ – H2O solutions with same ionic strengths. The quantitative composition of chromium(VI) solutions was confirmed qualitatively by UV–Vis. spectroscopy.

Authors: Buchko O. V.
Published: August 2021

Intermolecular interactions in the coordination compounds of cation-anionic type [Ni(phen)3][Ge(HCit)2]·2H2O (I), [Co(phen)3][Ge(HCit)2]⋅2H2O (II), [Co(H2O)2(phen)2]2[Ge(Cit)2]·4H2O (III) were characterized using Hirshfeld surface analysis. It was established that the biggest contribution in the Hirshfeld surface of anions have been made by the bonds H … В / О …Н (57,8 % (I), 59,6 % (II), 63,9 % (III)), H … H (28,2 % (I), 24,9 % (II), 31,4 % (III)). At the same time interactions C … H / Н … С are less significant (9,6 %, 11,2 % and 3,2 % for I, II, III, respectively). The calculated percentage contribution of different intermolecular interactions of cations in the crystals showed, that, unlike the anions, contacts H … Н (37,9 % (IА), 38,6 % (IB), 36,2 % (IIА и IIB), 38,8 % (III)) play dominating role, while contribution of H … В / О … Н is less (26,5 % (IA and IB), 28,3 % (IIA), 24,5 % (IIB), 26 2 % (III)). Furthermore, interactions C … H / Н … С are more significant than in anions (24,8 % (IА), 27,2 % (IB), 25,6 % (IIА), 26,2 % (IIB), 21,3 % (III). It is typical for cations to have С …С bonds (5,5 % in average) that give contribution less then 1 %. It was determined that voids volume in the crystals of compounds I–III is 751,74 (I), 778,21 (II) and 423,23 (III) Å3 and surface area is 1772,28 (I), 1821,36 (II) and 628,38 (III) Å2. The total volume of the voids (15 % in I, 15,7 %, in II, 22,4 % in III) testifies the lack of big cavities in the frames of the studied compounds. Thereby analysis of intermolecular interactions with the help of Hirshfeld surface analysis showed the dominating role of hydrogen bonds H … O / O …H and contacts H … H, and minor contribution of C … H / H … C and С … С bonds for all studied compounds. The absence of p-p stacking interactions between aromatic rings of 1,10-phenanthroline in the cations of complexes I–III was also pointed out.
DISCOURSE INVESTIGATION OF TEXTS OF ENGLISH TOURIST GUIDEBOOKS TO UKRAINE
Authors: Pryma Viktoriia
Published: August 2021

The research has been done within the framework of modern communicatively oriented linguistic paradigm. The article is devoted to the brief review of the texts of English-language tourist guides to Ukraine in terms of discursive research. The material of the analysis was electronic English-language tourist guides to Ukraine. The subject of the research is a discursive analysis of texts published on the pages of electronic guidebooks and the selection of separate examples. The study of the general principles of discourse, in particular tourism discourse, found out that some of its characteristics coincide with advertising discourse, and are targeted at attracting attention, encouraging interest, the emergence of unbridled desire and, finally, encourage action (in this case – tourist travel). The use of certain linguistic structures awakens in the readers’ imagination specific images - "schemata" - meaning "scheme", "template", "schematics". While conducting the study, we noticed that the information in the tourist guides appears as an additional for travelers, transmitted by modal verbs, in particular. Since tourism involves travelling in space and time, many online travel guides present cultural heritage as the primary means of attracting tourists to a particular country or region. Modern researchers believe that among the motives, which are necessarily recorded in tourist texts, there are the following ones: authenticity; search for new, unfamiliar and contrasting worlds. Verbal and non-verbal units of the English-language tourist texts are aimed at forming a complex attractive image of the country-place of rest. The results of the study will be useful in the further study of tourism discourse during lectures and practical classes.
Monopolizando el derecho a la vida: Un estudio sobre las injusticas del sistema de salud mexicano y cómo otras países latinoamericanos están aborando generaciones de inequidad
Authors: Molina Robert
Published: August 2021

El propósito de este estudio es resaltar el efecto de las décadas de inequidad que han sobrecargado al sistema de salud mexicano y por consiguiente, las consecuencias que tienen en los individuos quienes sufren como resultado. A través de la privatización de los sectores públicos en el país, ahora es más difícil que nunca para los ciudadanos mexicanos recibir una de las formas más básicas de derechos humanos: los servicios de salud pública y seguridad social. Y como resultado de esta problemática, las comunidades rurales sufren una gran falta de acceso a los recursos adecuados y como consecuencia nutren las tasas de mortalidad sin precedentes en todas las edades. El gobierno mexicano ha fallado a su gente y esto se puede observar, destaca en informes de agencias como la Medicina Social y la Salud Colectiva de América Latina (LASM / CH) y la Administración de Salud Pública. Sin embargo, a la luz de estas circunstancias, numerosos países latinoamericanos están dando un paso hacia un futuro mejor a medida que buscan aprobar reformas y legislaciones de salud pública más efectivas y eficientes. Esta mejora en base a la atención médica que ha provocado un impulso en la salud de la población mayoritaria. Además, a partir del uso de artículos académicos y datos primarios y secundarios, esta investigación proporcionada tiene como objetivo arrojar luz sobre lo que depara el futuro para la salud pública mexicana.

The purpose of this study is to highlight the effects of the decades of inequity that has burdened the Mexican health system and, consequently, the effects it has on the individuals who suffer as a result. Through the privatization of the public sectors in the country, it is now more difficult than ever for Mexican citizens to receive some of the most basic forms of human rights: public health and social security services. And as a result of this problem, rural communities suffer from a great lack of access to adequate resources, and, as a consequence, feed unprecedented mortality rates at all ages. The Mexican government has failed its people, and this can be observed, as it is highlighted in reports from agencies such as Social Medicine and Collective Health of Latin America (LASM/CH) and the Public Health Administration. However, in light of these circumstances, many Latin American countries are taking a step toward a better future, as they seek to pass more effective and efficient public health legislation and reforms. This improvement based on medical care has caused a boost in the health of a majority of the population. In addition, from the use of academic articles, as well as primary and secondary data, this research aimed to shed light on what the future holds for Mexican public health.
A Life Well-Lived: Discovering Motivation and Deeper Relationships by Contemplating Our Own Mortality
Authors: Williams Austin
Published: August 2021

For centuries, religious authorities and social pressures have discouraged individualsfrom contemplating mortality. A key component to the human sense of self is the ability to acknowledge the finite nature of life. All people experience some sort of death anxiety, whether conscious or not. Some experience thanatophobia, the fear of dying, more strongly than others. If managed in a healthy manner, death anxiety can serve as a motivating force to live a fuller life and deepen relationships with family and friends. In recognizing hidden components of death anxiety and finding consolation for the inevitability of dying, we can acknowledge our own mortality and explore both secular and spiritual approaches to death. For this thesis, I use painting as a visual medium to deliver my ideas and research in an immersive experience to the viewer. I conducted research by reading books and poetry, taking photographs, and viewing other artists’ work, online and in-person, from New York City museums and galleries. I have produced ten paintings of various size and technique that communicate how science and medicine, faith, meditation, and relationships alleviate death anxiety. Ultimately, I have found that painting has helped me to develop coping mechanisms that lessen my own death anxiety. I hope that by viewing my art, people will feel encouraged to consider aspects of their own mortality as well as ways to lead a fulfilling life.
Supporting English Language Learners' Experiences in the Classroom
Authors: Flynn Bailey
Published: August 2021

I was interested in studying English Language Learners (ELL) and how they are supported.Thus, I looked into how each level (US, Texas, Fort Worth, and McLean 6th Grade Center) supports these students. The support given to English Language Learners at McLean 6th Grade Center is extended time, dictionaries, audio options, differentiated texts, reading aloud, before school help, during lunch help, and after school help. The teachers track English Language Learners’ progress separately and adjust accommodations each six weeks to make sure each student's needs are being met. Based on these supports, I developed a survey that was sent to my students at McLean 6th grade, asking for their opinions on the support they were receiving. This survey would have originally been given in class, but due to the COVID-19 outbreak, the survey took place online. This limited my number of responses. I sent the survey to all 170 students and 51 responded. I then drew conclusions from my research and the survey on the effectiveness of supports offered.
An Analysis of Central Drivers of REIT Returns
Authors: Joyce Jordan
Published: August 2021

Many researchers have questioned whether real estate investment trusts (REITs) can act as a hedge for inflation or whether REITs can act as a safe haven for investors in the event of economic downturn. However, many studies lack basic data analysis or timely data to determine the dependence of REIT returns on various economic factors. The goal of this study is to act as a meta-analysis to synthesize the relationship between REITs and several potential risk factors. This study will extend beyond the timeline of previous studies, and will examine the relationship of several hypothesized risk factors. The results of this study can help brokers in their future decisions to hedge REIT risk in a portfolio. This study will use the historical returns from the National Association of Real Estate Investment Trusts (NAREIT) as well as six indices. This study will also use both univariate regressions and multivariate regressions to analyze the relationship between REITs and mortgage REITs and each representative index
Image-based Vehicle Re-identification Model with Adaptive Attention Modules and Metadata Re-ranking
Authors: Truong Quang
Published: August 2021

Vehicle re-identification is a challenging task due to intra-class variability and inter-class similarity across non-overlapping cameras. To tackle these problems, recently proposed methods require additional annotation to extract more features for false positive image exclusion. In this paper, we propose a model powered by adaptive attention modules that requires fewer label annotations but still out-performs the previous models. We also include a re-ranking method that takes account of the importance of metadata feature embeddings in our paper. The proposed method is evaluated on CVPR AI City Challenge 2020 dataset and achieves mAP of 37.25% in Track 2.

Background: Enriched composts supply the plant nutrients and add a sufficient amount of organic matter to the soil, which helps in improving the physical, chemical and biological properties of the soil. It helps to maintain and sustain soil fertility for enhancing crop productivity and also acts as a recess for microbes and enriches the soil with a variety of the indigenous micro-flora and fauna. Hence, the present investigation was carried out to study the effect of fertility levels and enriched compost on productivity, quality and profitability of soybean (Glycine max L.) in sub-humid southern plain and Aravalli hills region of Rajasthan. Methods: The experiment was undertaken during kharif 2018 at Rajasthan College of agriculture, Udaipur (Rajasthan) in a factorial randomized block design with three replications. The treatments were comprised of three levels of recommended dose of fertilizers (RDF) (control, 50% RDF and 100% RDF) and four levels of enriched compost (control, 2.0, 4.0 and 6.0 t ha-1). Result: The increasing fertility levels upto 100% RDF and enriched compost upto 4 t ha-1, significantly increased (P=0.05) the plant height, dry matter accumulation, number of pods per plant, number of seeds per pod, seed yield, haulm yield and protein and oil content in seed of soybean. However, the combined application of 100% RDF along with 6 t ha-1 enriched compost recorded higher seed and haulm yield. The results further revealed that the application of 100% RDF and 4 t ha-1 enriched compost significantly improved the productivity, quality and profitability of soybean under Typic Haplustepts soil.

Clinical perfectionism is the rigid pursuit of high standards, interfering with functioning. Little research has explored neural patterns in clinical perfectionism. The present study explores neural correlates of clinical perfectionism, before and after receiving ten 50-minute, weekly sessions of acceptance and commitment therapy (ACT), as compared to low-perfectionist controls, in specific cortical structures: the dorsolateral prefrontal cortex (DLPFC), medial prefrontal cortex (MPFC), right inferior parietal lobule (IPL). Participants in the perfectionist condition (n= 43) were from a randomized controlled trial evaluating ACT for clinical perfectionism and low-perfectionist controls were undergraduate students (n= 12). Participants completed three tasks (editing a passage, mirror image tracing, circle tracing) using functional near-infrared spectroscopy (fNIRS) to measure neural activation. Results indicate that ḥin the DLPFC and MPFC of the perfectionists whereas activation in the other tasks were relatively similar. There were no differences were observed in the right DLPFC, MPFC, and right IPL between the posttreatment perfectionist and nonperfectionist control groups. Our findings suggest an unclear relationship between neural activation and perfectionism.
Exposure Therapy for Misophonia: Concepts and Procedures
Authors: Rabasco Ana , McKay Dean
Published: August 2021

Misophonia, a condition marked by extreme intolerance to certain classes of sounds (e.g., respiratory or gustatory noises), has recently attracted increased research attention. As yet there are no evidence-based treatments, although some promising options are under empirical consideration. This paper presents a stress management and exposure therapy-based treatment protocol for adults with misophonia. The protocol details considerations specific to exposure therapy for misophonia, including unique considerations for developing hierarchies and example misophonia exposure exercises and exposure homework. Stress management approaches employed to facilitate engagement with exposure are also described. Two case examples are included, which illustrate the application of the misophonia treatment protocol. The first case describes treatment for a client whose misophonia symptoms are the primary focus and the second case describes treatment for a client whose misophonia symptoms are secondary to relationship difficulties. This protocol can be used to stimulate further treatment research for misophonia and guide treatment for individuals with misophonia.

Published: August 2021

Apart from the factors such as a good education-training program, family and social environment, the literary works that encourage the individuals to think and provide that they sense and self-learn can be considered as an important tool in providing an effective values education and character development. Considering the necessity of providing values education effectively from an early age, the importance of children's books and therefore the importance of children's literature is understood. It is observed that the academic studies have increased especially after 2014 within the context of the children's literature and values education. It has been determined that a significant portion of the theses written in Turkey in the field of values education concentrates on topics connected to Turkish education and teaching. The aim of this research was to determine and evaluate the methodological quality and researcher tendencies of the studies conducted at the graduate level, which had a certain increase in quantity until 2020. In the research, 99 theses approved by YÖK until 2020 in the context of children's literature andvalues education were examined in terms of the tag, research model and value or value category variables, on which they were based, of the relevant theses. In the context of children's literature and values education, when the postgraduate theses prepared in the universities which conduct studies at the postgraduate level were examined, it was observed that studies were conducted on certain academic fields and branches of science. When the types of works that were the subject of the sampling were examined, it was observed that especially fictional and plot-oriented genres were examined in the context of values education, and it was observed that all the theses revealed very different value and value categories although they wereexamined within the framework of a certain printed document's value or value category determined in various ways.

ZnO has received considerable attention since it has promising applications in electronic devices. Although many studies have explored the potential of ZnO as a promising material, the precise role of geometric in ZnO remains unclear. This study deals with the electronic structure of the ZnO monolayer using density functional theory (DFT). The DFT was used to investigate the band structure and density of states of the ZnO monolayer. It is observed that the structural change of ZnO from bulk to monolayer increases the bandgap by 1.84 eV without changes its natural characteristic. Moreover, This study provides information about the properties of the ZnO monolayer and its potential in electronic and magnetic devices application.

Authors: Ayuningtyas Aulia Indar , Nasri Sjahrul Meizar
Published: August 2021

Introduction: The work process of the Painting Area in a Manufacturing Company can pose a risk to physical and chemical health hazards for workers. Hazard analysis and identification, exposure assessment, and risk assessment  are, therefore, needed to protect the health of workers from these health hazards, which can later be used as a basis to determine appropriate controls so as not to have a negative impact on workers’ health. The purpose of this study was to analyze the hazards and their impacts on workers’ health through hazard identification measures, exposure assessments, risk assessments and control recommendations. Methods: Health Risk Assessment of physical and chemical hazards in the Painting Area was undertaken using a semi-quantitative method by calculating a risk assessment matrix using the guidelines from IPIECA & OGP in 2016. Results: Physical hazards were found in the form of lighting hazards, vibrations (arm vibration and whole body vibration), noise and heat pressure. Meanwhile, chemical hazards were found in the form of thinner vapor, solvent, NaNO3, H2SO4, NaOH, H3NSO4 and indoor air quality (CO, NO2, SO2, H2S). The results of the risk assessment matrix obtained 4 levels of risk hazards, consisting of 11.1% in the first priority, 50% in the second priority, 25.9% in the third priority and 12.9% in the condition that did not require immediate action. Conclusion: Physical and chemical health hazards were at 4 levels based on the calculation of risk control priorities. A hierarchy of risk control could be used to reduce the risk of health hazards.Keywords: health risk assessment, ipieca & ogp 2016, painting area, risk assessment matrix

Nitrogen Dioxide Concentrations in the Air in Increasing Superoxide Dismutase Enzyme and Malondialdehyde Serum Levels in Bus Terminal Officers
Authors: Kahar Kahar , Sulistyorini Lilis , Keman Soedjajadi
Published: August 2021

Introduction: Free radicals in the air such as NO2 , O3 , PM2,5 induce the production of reactive oxygen species (ROS) in the body and stimulates the production of superoxide dismutase (SOD) enzyme. Imbalanced levels of free radicals and antioxidants will trigger the production of malondialdehyde (MDA). This study aimed to analyze the correlation between NO2 concentrations in the air with SOD and MDA levels in bus terminal officers. Methods: This study was an analytical observational and used a cross-sectional design. The population included terminal operational officers and desk administrative officers in the bus terminal. A number of 12 people was chosen as a sample calculated with averaging formula between case and control. The measurement of NO2 concentrations in the ambient air was performed using the Griess Saltzman method. The ELISA method was utilized to analyze the levels of the SOD enzyme, and the TBARS method was used to analyze the level of MDA serum. A statistical test was conducted using a Mann-Whitney test and Independent-2 Sample T-test. Results and Discussion: The average of NO2 concentrations in the ambient air showed 106.5 µg/Nm3 and in the administration room at 17.8 µg/Nm3 . There was a very significantly higher exposure to NO2 in the air towards the level of SOD enzyme (p < 0.01) and to the level of MDA serum (p < 0.01). Conclusion: The high level of exposure to NO2 in the ambient air will increase SOD enzyme and MDA serum production in the body. It is recommended that the officers consume more fruit and vegetables containing vitamins C and E to fulfill the daily nutritional intake for antioxidants, and for the operational officers, always use a mask

Introduction: The current Covid19 pandemic has overgrown, as reported statistics show. It causes multiple effects in human life, which one a majority of them doing all activities from home that increase the domestic waste production. The inadequate conventional handling management and a large amount of waste generated thrown away by open dumping. Methods: This study was carried out with a descriptive qualitative approach to describe all information of a good understanding in implementing a waste management system in Bekasi Regency. Mapping and identifying all the waste management process variables were then arranged dynamically using the Causal Loop Diagram (CLD) techniques. Results and Discussion: It should be noted that the variables influence many other variables because the policies applied have much influence on other environments. In the formed CLD in this study, the Covid19 pandemic variable will directly affect 3 (three) other variables such as public consumption patterns, economic conditions, and waste volume. The limited land and high costs were the problems that will hinder the success in waste management in Bekasi Regency. Conclusion: The CLD model shows that the waste management process did not get much attention from the community and managers during this pandemic. The thing that is not being overseen is the increase in the volume of domestic waste because most people choose to work from home, school holidays, and many outside activities are reduced. This CLD model shows that it is necessary to immediately improve waste management so that all waste that enters the landfill can be appropriately processed.

Curved slit caisson has been the preferred structural type of breakwater in South Korea, and effective control of stem waves is a crucial design factor significantly affecting the performance of a curved slit caisson breakwater. Most of the past studies on stem waves heavily relied on wave drivers like the cubic Schrödinger Eq. due to the intrinsic difficulties in analyzing stem waves. However, considering the perturbation method evoked in the derivation of cubic Schrödinger Eq., the wave driver mentioned above could give erroneous results in the rough sea due to the higher-order waves that appeared in the wave field by resonance wave-wave interaction. In this rationale, in this study, the numerical simulation was implemented to verify the stem wave control effect of curved slit caisson using the ihFoam, toolbox having its roots on OpenFoam. It was shown that curved slit caisson breakwater effectively alleviates the scope and height of stem waves.

The internet has offered numerous opportunities for educational content delivery. The main current delivery models for learning a language online range from more formal structured approaches provided by schools and universities, which typically take place in a VLE (Virtual Learning Environment) or LMS (Learning Management System), to more informal unstructured approaches, including Virtual Worlds like Second Life and MMORPGs (Massively Multiplayer Online Role-Playing Games) like World of Warcraft.
The purpose of this study is to analyse the experiences and perceptions of the online digital tools that provide engagement with the English language outside the classroom by the non-linguist students at a Ukrainian public university. The study is based on the quantitative and qualitative data collected employing an online questionnaire including Likert-type ratings, multiple-choice questions, and free-text responses to open questions. The questionnaire inquires about students’ experiences with 17 technologies not related to their classroom activities, how frequently they are used, how helpful the students find them for their language acquisition in general, and how useful they are considered for the development of particular language competencies (writing, reading, speaking, listening, pronunciation, grammar, communicative competence). The results of the survey attest to regular students’ engagement with the English language involving online technologies, which leads to implications for foreign language learners, teachers, and researchers of second language acquisition for incorporating online digital tools for foreign language acquisition beyond the classroom. Being aware of how students engage with technology outside the classroom may facilitate educators in increasing learners’ engagement with the foreign language, provide additional practice, and produce an emotional response, which increases retention of information.

Authors: Hrdličková Zuzana
Published: August 2021

It is evident from the PISA 2018 results that a trend in mean performance in reading has been declining in the Slovak Republic. The KEGA Project “Idioms in Business Communication”, run at the Department of English Language, aims at improving reading literacy, widening formal and informal vocabulary and facilitating business communication. Both traditional and modern styles of language teaching are used. The control group of students does a traditional course and the experimental group of students enrols in a “Business Communication” e-course on LMS Moodle platform, as well. With the use of the Internet and supporting materials, this group is involved in various activities. The paper compares the study results of 144 first-year and 97 second-year students of the University of Economics in Bratislava achieved in departmental standardised business English tests after completing three courses in business English for advanced students. The method of Hypothesis Testing (t-Test) assesses the significance of the difference between the levels of knowledge of both groups. The research findings prove that the experimental group of students achieved better results in final evaluation than the control group of students. The results also confirm that an alternative form of business English teaching was effective.

The purpose of the article is to prove theoretically and check experimentally the effectiveness of explicit models for language learning strategies based on the instructions in the process of professionally oriented English communication. The hypothesis of the research implies that the level of professional English communicative competence will increase in the case of combining such models as “top-down” and “bottom-up” while professionally oriented English communication. The study employed the mixed research design method as quantitative (Likert’s scale, Bespalko’s learning coefficient, Fisher’s criterion) and qualitative (interpretation of questionnaire results) methods. The levels of explicit models using for language learning strategies are defined by the results of the conducted survey of 116 pre-service teachers of Vinnytsia Mykhailo Kotsiubynskyi State Pedagogical University. One of the conditions of experimental learning is a sequence of stages in the process of applying two explicit models for language strategy learning instruction “top-down” and “bottom-up” in the process of pre-service teachers’ professionally oriented English communication. Findings. The results of the control test at the final step of the experiment have confirmed the effectiveness of two variants of explicit models for language strategy learning instruction in the process of professionally oriented English communication. The analysis of experimental training results has shown the formation of professionally oriented English communicative competence at the level B2, as well as a significant increase in the participants’ knowledge, skills and abilities of foreign language learning strategies. Implications for research and practice. Combining “top-down” and “bottom-up” explicit models for language learning strategy instruction contributes to more effective assimilation and expansion of the repertoire of learning and communicative strategies and improves professionally oriented English communicative competence of pre-school teachers at university level.

Published: August 2021

The paper presents the ideas on integration of English language academic writing into the training of Mater of Pharmacy students. The academic literature demonstrates a powerful didactic potential for the development of both language and professional competence of students majoring in pharmacy. This fact is evidenced by the empirical study that demonstrates the finding reflected in students’ graduation academic project performance. As a measurement tools we employed assessment rubrics of the graduate project, content analysis and questionnaire on teachers’ feedback. The participants of the study were students from the Pharmacy faculty and teachers of English for Academic Purposes in cooperation with teachers of pharmacy. Together they outlined the criteria for the texts selection. According to the results, students mastered not only academic writing skills, but also the skills of information processing and evaluation, critical thinking, presentation of information and academic integrity. The paper also presents methodological recommendations on academic texts selection for pharmaceutical students and forms of teachingacademic writing to students of non-linguistic specialties. The results of the study allow to draw the conclusion academic writing course will enhance professional competence and reduce students’ misinterpreting of academic language.
Zeroize: A New Method to Improve Utilizing 5G Networks when Running VoIP over IPv6
Authors: Kolhar Manjur
Published: August 2021

5G technology propagation curve is ascending rapidly. 5G will open up the horizon to improve the performance of many other IP-based services such as voice over IP (VoIP). VoIP is a worldwide technology that is expected to rule the telecommunication world in the near future. However, VoIP has expended a significant part of the 5G technology bandwidth with no valuable use owing to its lengthy packet header. This issue even worsens when VoIP works in IPv6 networks, where the wasted bandwidth and airtime may reach 85.7% of 5G networks. VoIP developers have exerted many efforts to tackle this snag. This study adds to these efforts by proposing a new method called Zeroize (zero sizes). The main idea of the Zeroize method is to use superfluous fields of the IPv6 protocol header to carry the digital voice data of the packet and, thus, reduce or zeroize the VoIP packet payload. Although simple, the Zeroize method achieves a considerable reduction of the wasted bandwidth of 5G networks, which also directly affects the consumed airtime. The performance analysis of the Zeroize method shows that the consumed bandwidth is saved by 20% with the G.723.1 codec. Thus, the Zeroize method is a promising solution to reduce the wasted bandwidth and airtime of 5G networks when running VoIP over IPv6.

The screening and treatment of acid mine drainage (AMD) using Na2FeO4 has been explored. Elemental composition was performed using an ICP-OES for the raw and treated AMD. The AMD samples were collected from three different sampling sites (RTW1, RTW2 and RTW3) in Pretoria, South Africa with acidic pH ranging between 2.50 and 3.13. Total dissolved solids and Electrical Conductivity of AMD samples ranged between 960 and > 1000 mg. L-1, 226 and 263 µS. cm-1, respectively. The final pH of treated water samples increased up to ≥ 9.5 after treatment with Na2FeO4. Sodium ferrate showed dual functions by removing metals and raising the pH of the treated water. Concentrations of most trace elements were not complying with WHO and DWAF guideline standards in raw AMD while after treatment with Na2FeO4 the concentrations were below guidelines for domestic and irrigation purposes.
