Published: April 2021

Об'єктом дослідження є методи побудови математичної моделі оптичних каналів передачі інформації в інформаційній системі судової експертизи, предметом дослідження – оптичні канали передачі інформації. Наводяться результати аналізу передачі інформації у інформаційній системі судової експертизи, які встановили, що при використанні оптичних каналах зв'язку найбільші проблеми виникають через неоднорідність середовища поширення. Тому задача організації контролю стану обміну інформації в комп'ютерних мережах інформаційної системи є бузумовна актуальною. Вирішення цієї складної і багатогранної задачі в статті базується на попередніх дослідження, які біли виконані з використанням формалізму континуальних інтегралів (КІ) Феймана .Метою даної статті є удосконалення математичної моделі оптичних каналів передачі інформації в інформаційній системі судової експертизи.В ході дослідження використовуються методи математичної фізики, теорії поля, математичної статистики та теорії ймовірностей, нелінійної оптики, теорії систем. Дані методи були інтегровані в загальний метод, що дозволило удосконалити математичну модель оптичних каналів передачі інформації.Використовуючи аналітичні співвідношення, отримані в попередній статті, були сформульовані рівняння кореляційних функцій, в тому числі, і довільного порядку. Це стало можливим при використанні континуальних інтегралів Феймана. В статті наведено аналіз отриманих рівнянь для деяких часткових умов. У статті встановлено, що використання КІ дозволяє просто записувати як рішення рівнянь будь-якого порядку (хоча звичайно запис рішень у вигляді КІ є перенесенням труднощів з однієї області - рішення рівнянь в приватних похідних в іншу, тому що точно обчислюються КІ лише спеціального виду - гаусові ), так і вирази для таких величин, які не можуть бути описані замкнутими рівняннями, уникаючи при цьому введення зайвих параметрів. Складність і труднощі рішення рівнянь для моментів зростає з ростом їх порядку: якщо рівняння навіть для просторових функцій когерентності першого і другого порядків вирішуються в загальному вигляді, то аналітичне рішення рівняння для більш високих моментів отримати вже не вдається. Зазвичай для розчеплення ланцюжка і отримання замкнутих рівнянь для моментів даного порядку приймаються певні статистичні гіпотези про рішення. При формулюванні завдання в терміналах КІ такі статистичні гіпотези проявляються як деякі наближення для подинтегрального вираження, що дозволяє простежити за характером наближень і визначити межі їх застосовності. Таким чином, з'явилася теоретична можливість удосконалення математичної моделі оптичних каналів передачі інформації на основі використання формалізму КІ для отримання рівняння кореляційних функцій
Centro de detención: racismo y lucha migrante en Estados Unidos
Authors: Aguilar Román Carolina
Published: April 2021

Estados Unidos de América tiene el sistema de detención para migrantes más grande del mundo. Este artículo argumenta que esos centros son instituciones racistas. Usando un marco analítico novedoso que integra los estudios de encarcelamiento y las luchas migrante, se creó un modelo. El cual, identifica cuatro factores que posibilitan el racismo sistemático en los centros de detención para migrantes: 1) sistema de encarcelamiento masivo; 2) criminalización hacia personas migrantes; 3) racialización; y 4) género. Se completa el análisis con la conclusión de que las luchas migrantes, desafían, rechazan y resisten el racismo. Y algunas veces lo derrotan, ese es el caso de la estrategia de desobediencia civil de infiltrarse en centros de detención.

Indigenous Knowledges and Scholarly Publishing
Authors: Boyd Geoffrey
Published: April 2021

At its core, academic knowledge production is predicated on Western notions of knowledge historically grounded in a Euro-American, White, male worldview. As a component of academic knowledge production, scholarly publishing shares the same basis of Whiteness. It excludes knowledge that doesn’t conform to White, Western notions of knowledge, forces conformity to (and therefore reinforcement of) a Western standard of writing/knowledge, and leads to a reverence of peer-reviewed literature as the only sound source of knowledge. As a tool of scholarly publishing and the editorial process, blind peer review, though perhaps well-intentioned, is fraught with problems, especially for BIPOC researchers and writers, because it fails in its intended purpose to drastically reduce or eliminate bias and racism in the peer review and editorial processes; shields peer reviewers and editors against accusations of bias, racism, or conflicts of interest; and robs BIPOC, and particularly Indigenous, writers and researchers from having the opportunity to develop relationships with those that are reviewing and publishing their work.

A Study on the Operating Status of Elective Subject According to the 2015 Revised High School Mathematics Curriculum
Authors:   The Korea Society Of Educational Studies In Mathematics, Lee Hwayoung
Published: April 2021

The 2015 revised high school curriculum has been designed to support students’ selection of subjects considering the student's career path, and the mathematics department also organized general/ career elective courses. This study was conducted to derive implications for ensuring students' choice of subjects ahead of the implementation of the high school credit system. First of all, focusing on subject options, I looked at the changes in Korean curriculum, composition of foreign mathematics subjects, and college entrance subjects, and the current status of ‘selective- oriented curriculum' in 1,709 general high schools nationwide and status of co-curriculum operation by education board of city or province. Several implications have been derived based on the findings. It was suggested that elective subjects and career tracks should be prepared so that students can choose their courses according to their career path, and that universities should designate essential subjects so that students can learn what they need and go to college. In addition, it was proposed that improvements in the system to prevent grades from being disadvantaged by the selection of mathematics subjects, and improvements in the completion path and subject composition should be made.

Reliabilita a faktorová validita dotazníku SPARO
Authors:   Masaryk University Brno, Czech Republic, Cígler Hynek , Rudá Adéla
Published: April 2021

In 2009, the SPARO questionnaire was one of the most used assessment methods in the Czech Republic (Urbánek, 2010), especially between psychologists in human resources, prisons, police, or the army. However, empirical evidence of its reliability and validity is missing. Using a significant sample of police officers and applicants to police, we researched the questionnaire's re­liability and factor validity. About half of the scales do not have adequate internal consistency; the majority of them are not unidimensional. Factor validity is questionable, especially in the main components of the questionnaire, which are highly correlated. These correlations were also present in the original standardized samples as our and original correlation matrices do not differ. The factor structure of the two general factors items is not clear and two dimensional. Our results do not support the use of the questionnaire in practice. It is necessary to confirm its’ predictive validity; the criterion validity is evaluated in our follow up study (Cígler & Rudá, 2021).
Souběžná validita dotazníku SPARO a MMPI 2
Authors:   Masaryk University Brno, Czech Republic, Cígler Hynek , Rudá Adéla
Published: April 2021

In the previous study (Cígler & Rudá, 2021), we were not able to confirm satisfactory internal consistency and factor validity of the SPARO questionnaire. However, further psychometric properties are also necessary to consider the questionnaire's va­lidity and usefulness in practice. In this follow up study, we examined its criterion validity to MMPI-2, which is used globally and thus has broader empirical support. Despite that, we did not find any support for neither convergent nor divergent validity of the main components, general factor, and the credibility score (L) of SPARO questionnaire to selected MMPI-2 scales. The only exception was the emotional variability scale (EM). As a minor result, we also examined the internal consistency and factor validity of MMPI-2 scales as no other Czech study concerning the questionnaire exists. Neither reliability nor factor validity was satisfactory. Finally, we argue that using the SPARO questionnaire in regular practice cannot be recommended. Cautious use of the MMPI-2 is possible, regarding international validation studies, however, further Czech research is needed, especially in the predictive validity.

There is a lot known about how drug use and addiction affect a person´s life – with both negative physical and psychosocial outcomes. When coping with adverse events some positive transformative changes can be shown and that should be the matter of our interest as well. This review aims to gather, describe and integrate the results of nine empirical studies focused on personal growth associated with recovery from addiction. We had found diverse theoretical approaches as well as different methodology and survey sample characteristics within studies, such as the difference in groups of substances abused by respondents, number of their relapses and treatments as well as the treatment programs they went through. Review findings show that recovery goes beyond abstinence. The studies agree on the importance of social support, perceiving recovery as an ongoing process of growth and an opportunity to start a new life or find meaning in life even though the perspectives of the researchers vary. The article points out the research gap in addiction treatment, which may encourage the clients to profit from their addict´s expe­riences, use them to support the recovery process, and boost their quality of life and personal growth.

Published: April 2021

The measures of children´s and adolescents´ cognitive performance in the Czech Republic have been so far assessed mainly by intelligence tests, such as the Wechsler Intelligence Scale (WISC-III) or the Intelligence and Developmental Scale for Children (IDS). However, there have been growing requirements for more accurate examination of individual cognitive profile for which the neuropsychological tests are not available. So far, in the pediatric population, we can only examine more thoroughly some of the cognitive functions, such as memory. For many other tests, normative data are available for the Czech population only in a narrow age range. The Neuropsychological Battery for Children aims to become a quality and affordable neuropsychological tool for assessing the neuropsychological development of children aged 6–19 years with appropriate standards. The paper briefly describes this test battery.

Neuropsychology in the Czech Republic is increasingly becoming a competitive field at the international level. However, the availability of standardized neuropsychological test methods is significantly limited compared to abroad. This limits both the further development of the field and the provision of evidence-based health care. One of the lacking methods in Czech practice is the Brief Visuospatial Memory Test-Revised (BVMT-R). The report briefly introduces this neuropsycholo­gical test.
Sociální psychologie: teorie, metody, aplikace (recenze)
Authors:   Hussite Theological Faculty Charles University, Czech Republic, Novák Petr
Published: April 2021

The evolution of social psychology, with origins emerging from the late 19th century and its’ wide area of impact, caused an accumulation of a significant amount of various theories and findings. The aim of experienced editors together with a numerous team of authors was to “in one publication, describe the social psychology as one unit composed of fundamental topics necessary for the understanding of what social psychology truly is” (p. 18). In sixty methodically and structurally ordered chapters, which are divided into three relatively independent sections, we are presented with either theoretical background (section A), methodological take (section B), or strictly practical application (section C) of social psychology topics.
Exploring association between countries’ self-reported International Health Regulations core capacity and COVID-19 control outcomes
Authors: Tsai Feng-Jen , Lin Chia-Ping , Turbat Battsetseg
Published: April 2021

Background

This study aimed to evaluate the association between countries’ self-reported International Health Regulations (IHR) capacity and their COVID-19 control outcomes.

Methods

Scores from the countries’ 2019 self-assessment report (State Party Self-Assessment Annual Reporting, SPAR) were used to represent countries’ core capacities. Two scales were used to represent countries’ COVID-19 control outcomes: “governmental response to COVID-19,” which included case public health (PH) measure intervals, case-PH measure speeds, government response stringency; and scale “COVID-19 outbreak progress within the country,” which included days between the first global and domestic cases, number of case growing weeks, and percentage of case growing weeks between 01 January 31 May, 2020. One hundred and seventy-four countries with COVID-19 data were included in the analysis. The human development index (HDI), health workforce density (HWD), health expenditure (HE), and international travel volume (ITV) were collected as controls. Chi-square and logistic regression analyses were carried out.

Results

Countries with high SPAR scores responded significantly earlier, but 49.46% of countries with high and very high HDI implemented public health measures within a month of the first global case, whereas 20% of countries implemented PH measures after there was already a domestic case. Compared with low ITV countries, countries with high ITV had a 15 times greater risk of early importation of COVID-19 cases and a greater risk of having more weeks over which case numbers increased. However, countries with low HE and SPAR scores as health service provision were at significantly higher risk of community outbreak escalation.

Conclusions

To some extent, countries’ COVID-19 control outcomes were reflected by their SPAR scores. However, SPAR do not measure the effectiveness of communication mechanisms between health professionals and political leaders in the activation of response systems. The country-based health expertise and health system is crucial to limiting further viral spread in the community.
Barriers and facilitators of traditional health practitioners’ regulation requirements: a qualitative study
Authors: Nzimande Siyabonga I , Moshabela Mosa , Zuma Thembelihle , Street Renée , Ranheim Albertine , Falkenberg Torkel
Published: April 2021

Background

Regulations could create benefits and opportunities for traditional health practitioners (THPs) and traditional medicine (TM) users in this new era of traditional medicine systems (TMS) as the growing international popularity propels this. The 1978 International Conference on Primary Health Care played a significant role in recognising THPs. To date, millions of people across the globe continue to utilise THPs. The issues of safety and scientific validation led the WHO to recommend regulations of TM. This was also supported by pressures from the realisation that culture and spiritual life is associated with traditional healing. This paper seeks to understand barriers and facilitators surrounding THP regulation implementation.

Methods

The qualitative research approach involved five focus group discussions sampled from five Kwazulu-Natal district municipalities (one in each district). Participants were selected using district THP councils and a snowballing technique to recruit non-functional THP councils. Data collection tools included case summaries and a focus group discussion guide. Data was analyzed using Braun & Clarke’s (2017) six-phase thematic analysis framework.

Results

Themes identified included purposes of being registered with the THP council; registration being viewed as a tax collection instrument; and recognition and legitimacy of THPs. Most THPs were uncertain about why they should be registered and therefore struggled to identify benefits of being registered. Moreover, several THPs viewed registration as tactic to oppress and squeeze them to contribute towards the countries taxation system. Recognition and legitimacy were the only benefits identified, as THPs saw registration as a gateway into mainstream health and believed it would separate them from charlatans.

Conclusions

THPs generally had mixed feelings about being registered; most saw very little, if any, potential benefits in being registered, except for recognition and legitimacy. THPs who found registration beneficial, remained sceptical about how it would impact their intellectual property and belief systems. Further exploration of the role of THP associations, their history and evolution and the influence they could have in driving THP regulation implementation process is warranted, especially since THPs found registering with such associations to be beneficial.

Published: April 2021

Residues of antibiotic drugs in food and food products have been received much attention in recent years because of growing food safety concerns for public health. There are serious effects of antibiotic residues in meat for human consumption (e.g., increasing antimicrobial resistance, carcinogenicity, mutagenicity, and hypersensitivity). In this study, we used broiler chicks as a laboratory animal to detect the colistin sulfate antibiotic residue for human health concerns. The day-old broiler chicks were collected and reared for up to 31 days. The treatment was started from the day 16th until sacrifice. The chicks were randomly divided into three groups namely control group (Group A), discriminate antibiotic group (Group B) and indiscriminate antibiotic group (Group C) on the 14th day. The discriminate group was treated with an antibiotic, colistin sulfate maintaining the withdrawal period of one week. In case of indiscriminate group the withdrawal period was not maintained and antibiotic treatment was continued till the day of sacrifice. The body weights of the birds were recorded daily. The mean body weight was highest in indiscriminate group (1261.15±16.37gm) followed by discriminate group (1156.15±18.23gm) and the lowest was in control group (1008.49±18.11gm). The differences among mean weight gain were statistically significant (P<0.05) in antibiotic treated group compared with control group. The Thin Layer Chromatography revealed that all the samples were positive in indiscriminate group and in case of Liver, Kidney and Spleen, it was 100%. In case of discriminate antibiotic group all the samples were positive except thigh and breast muscle and the percentage was highest in Liver sample (66.67%). There was no positive sample in control group. The results were statistically significant (P<0.05). From the above findings, this research could be considered a need based research in Bangladesh to ascertain the influential effect of antibiotic abuse in poultry industry.
A note on the dynamics of food systems in Algeria: The example of the Ziban and the Souf
Authors: Salah Bouchemal
Published: April 2021

This work is about a note which records some results concerning a research undertaken in Algeria. It is part of a cooperation between several Mediterranean teams. Its objective is to report on current developments in agricultural practices on the environment and on the territories, in order to design conceptual scenarios that will draw profiles that can ensure sustainable food security in cities and the maintenance of biodiversity. Similarly, it will have another interest, it is to develop an exhaustive and homogeneous database on the western part of the Mediterranean basin. For Algeria, the studied areas are distributed on a biogeographical section, from the Mediterranean coast to the Sahara, that is to say, places sufficiently representative of the North-South ecological degradation and of the diversity of situations. The results reported in this note concern two Saharan areas, the Ziban and the Souf, as the final results of the research have not yet been achieved, since the project is still ongoing. In these two areas, agriculture in the past was limited to the traditional oasis system, just to ensure the subsistence of the inhabitants, but today, several factors have contributed to a revival of agriculture whose development is spectacular. Thus, the Ziban and the Souf have become very important food producing areas and even exporters of food products. However, it should be pointed out that this dynamic, if it is a source of innovation, it has negative consequences on the oasis heritage and on the environment.

Psychoanalytische Anmerkungen zu »Destruktivität« in Supervision und Beratung
Authors: Pollak Thomas
Published: April 2021

Die wichtigste Quelle von Destruktivität sieht der Autor in einem Hass, der aus traumatisch-negativen Kindheitserfahrungen stammt. Sozialpsychologisch sei die Idealisierung bedeutsam: Soziale Gruppierungen können als idealer Ort des Schutzes gegen Ohnmacht, Scham und Schuld erlebt werden; wer dieses Ideal bedroht, kann Destruktivität auf sich ziehen. In Supervision und Beratung kann Destruktivität auf der Ebene des »Falles« erscheinen, auf der Spiegelungsebene des Falles in der Supervision oder direkt zwischen Supervisand*in und Supervisor*in. In einem Fallbeispiel, der Krisenberatung einer Klinik, wird die Destruktivität auf die Angst vor Veränderung zurückgeführt. Sie zeigte sich in der Spaltung zwischen Team und Leitung und wurzelte in einer Idealisierung der Vergangenheit.
Gemeinsam in den Abgrund
Authors: Knie Andreas
Published: April 2021

Das Auto ist der materielle Kern unserer Geschichte und Basis für volkswirtschaftliche Prosperität und individuelle Freiheit. Diese politisch hergestellte Erfolgsgeschichte verschaffte dem Automobil eine Schlüsselstellung. Doch ist das private Auto noch zeitgemäß? Städtische Räume definieren sich neu und das Auto als Massenverkehrsmittel hält sein einstiges Versprechen für mehr gesellschaftliche Teilhabe und ein gutes Leben nicht mehr. Währenddessen verpasst die Politik den Wandel und sichert bewusst die Privilegien des Autos. Auch die deutsche Automobilindustrie ignoriert die Themen und Notwendigkeiten einer modernen und mobilen Gesellschaft und blockiert Veränderungen zu alternativen Antrieben lieber, als Teil davon zu sein. Doch die »Komplizenschaft« zwischen Hersteller, Staat und Verbrauchern bröckelt und Stadtplanung, Industrie und Politik müssen endlich anfangen, an echten Alternativen zu arbeiten.

Published: April 2021

Подобраны условия ферментативного гидролиза с применением эндопротеиназы Glu-C, рабочая область рН которой соответствовала рН-диапазону стабильности белка. Экспериментально подтверждено отсутствие аутогидролиза фермента. Анализ полученных пептидных карт, основанный на оценке стабильности времен удерживания и интенсивности 7 основных пиков, позволил выбрать их в качестве реперных. Масс-спектрометрический анализ состава фракций, соответствующих данным пикам, позволил идентифицировать 81 аминокислотный остаток, что соответствует 50 % аминокислотного покрытия первичной последовательности исходной молекулы. Разработана методика пептидного картирования с последующим разделением продуктов ферментативного гидролиза методом ВЭЖХ. Полученные результаты свидетельствуют о специфичности и стабильности полученных пептидных карт. Методика может быть использована при подтверждении подлинности структуры рекомбинантного интерферона бета-1b, не содержащего вспомогательных веществ белковой природы.

Australian Research in Early Childhood Education and Care: Insights Into the Actual; Imagining the Possible
Authors: Garvis Susanne , Phillipson Sivanes , Phillipson Shane N.
Published: April 2021

Early childhood education and care (ECEC) remains a priority area for public policy, internationally and in Australia. However, an analysis of empirical research published internationally up to 2008 has identified a bias toward positivist methodologies within a “scientific/psychological’ rather than educational perspective and with a focus on the interactions between preschoolers, family, and child care variables. For some researchers, this bias raises concerns that public policy in ECEC is based on limited research perspectives. This chapter examines research focusing on the Australian context and published between 2010 and 2014 to determine whether this bias exists in Australian research. We explore the quality of ECEC research to develop an overall understanding of the current situation of ECEC research in Australia. Our findings suggest that Australian research in ECEC is very dissimilar to research published internationally, especially in its reliance on qualitative paradigms and a focus on the educators (principals, teachers, and teacher aides). The strong qualitative focus may allow a diverse range of voices within the ECEC sector to be heard and identified, moving beyond traditional notions of historically marginalized individuals and communities that dominate other education research areas.
Considerations for Evidence Frameworks in Education Research
Authors: Taylor Joseph A. , Davis Elisabeth , Michaelson Laura E.
Published: April 2021

In this chapter, we describe and compare the standards for evidence used by three entities that review studies of education interventions: Blueprints for Healthy Youth Development, Social Programs that Work, and the What Works Clearinghouse. Based on direct comparisons of the evidence frameworks, we identify key differences in the level at which effectiveness ratings are granted (i.e., intervention vs. outcome domain), as well as in how each entity prioritizes intervention documentation, researcher independence, and sustained versus immediate effects. Because such differences in priorities may result in contradictory intervention ratings between entities, we offer a number of recommendations for a common set of standards that would harmonize effectiveness ratings across the three entities while preserving differences that allow for variation in user priorities. These include disentangling study rigor from intervention effectiveness, ceasing vote counting procedures, adding replication criteria, adding fidelity criteria, assessing baseline equivalence for randomized studies, making quasi-experiments eligible for review, adding criteria for researcher independence, and providing effectiveness ratings at the level of the outcome domain rather than the intervention.
Sashaying Across Party Lines: Evidence of and Arguments for the Use of Validity Evidence in Qualitative Education Research
Authors: Cian Heidi
Published: April 2021

Though the concept of validity is rooted in positivism, recent scholars have expanded the definition of validity to reflect more progressive paradigms, opening the door to consideration of validity in qualitative education research. Despite this evolution, to date a review of validity evidence in qualitative research has yet to be undertaken even though products offering recommendations for using validity or validity analogs (e.g., trustworthiness) in qualitative work has accelerated. In this chapter, I provide an overview of the history of validity in qualitative research and give an assessment of the use of validity evidence as presented in qualitative articles published in a high-impact journal. I use the results of this assessment to highlight validity practices that are well-represented in the research as well as those that are underrepresented, offering recommendations for how researchers can support the presentation of their work through reflection on these underrepresented elements. Additionally, I forward suggestions as to how qualitative researchers may approach using validity frameworks in planning their studies. Implications for qualitative and quantitative researchers are also discussed, along with suggestions for future work in exploring the use of validity in qualitative education research.
Assessing the Quality of Education Research Through Its Relevance to Practice: An Integrative Review of Research-Practice Partnerships
Authors: Welsh Richard O.
Published: April 2021

The contemporary social, economic, and cultural conditions within and outside the academy prompt important questions about the role of research in education policy and practice. Scholars have framed research-practice partnerships (RPPs) as a strategy to promote evidence-based decision-making in education. In this chapter, I interrogate the notion that RPPs offer an insightful framework to consider how the quality of research can be measured through its use. The findings suggest that using RPPs to assess the quality of education research enhances the relevance to policy and practice as well as attention to the quality of reporting, and pivots from the preeminence of methodological quality. RPPs increase local education leaders’ access to research and bolster the use of research. RPPs may also strengthen the alignment between education research and the public good. Notwithstanding, employing RPPs as a vehicle to assess research quality has its challenges. Valuing the work of RPPs in academia is a work in progress. Building and sustaining an RPP is challenging, and there is still much to learn about the ways in which RPPs work and overcome obstacles. Assessing the impact of RPPs is also difficult. Future considerations are discussed.
Absorptive Capacity as a Means of Understanding and Addressing the Disconnects Between Research and Practice
Authors: Crain-Dorough Mindy , Elder Adam C.
Published: April 2021

The research community focuses on conducting research with the purported goal of improving educational practice, yet the two communities largely remain disjointed. This chapter explores the major disconnects between research and practice from the perspectives of both the practice and the research communities, and we present strategies for establishing stronger connections based on the results of our literature analysis. We argue that examining the research–practice gap through the lens of absorptive capacity provides elucidations about the disconnects, and it facilitates the organization of research-based strategies. As a result, both communities are able to jointly determine what constitutes quality research evidence and attenuate the gap between research and practice.
ORGANOSULFUR COMPOUNDS OF COKE OVEN GAS AND THEIR CONTRIBUTION TO EMISSIONS OF SULFUR DIOXIDE FROM THE SMOKESTACKS OF COKE BATTERIES

The article touches upon the problem of cleaning of the coke oven gas from sulfur compounds, which is relevant in connection with the requirements for reducing of the sulfur dioxide emissions into the atmosphere and ensuring of the environmental safety of production in general. At present, the sulfur dioxide emissions from coke-chemical plants account for about 20 % of the total emissions of pollutants from coke ovens and are calculated from the concentration of hydrogen sulfide in coke oven gas after its purification before feeding to coke oven batteries heating systems. However, in addition to hydrogen sulfide, coke oven gas also contains organosulfur compounds such as carbon disulfide (CS2), carbon oxysulfide (COS), thiophene (C4H4S), mercaptans, etc. The authors of the article carried out a study to determine the content of organic sulfur compounds in the original and purified coke oven gas, as well as the contribution of these substances to sulfur dioxide emissions from the smokestacs of coke oven batteries. The calculation has been performed of the additional volume of sulfur dioxide, which is formed due to the combustion of organosulfur compounds of coke oven gas during its combustion in the heating system of coke ovens. It has been found that under the condition of complete conversion of organic sulfur compounds into sulfur dioxide during the combustion of coke oven gas in the heating system of coke ovens, the concentration of sulfur dioxide in flue gases can be approximately 25.0-35.0 mg/m3 (in recount on 5 % oxygen content in flue gases). It has been also shown that the share of emissions of the sulfur dioxide formed as a result of the combustion of hydrogen sulfide in coke oven gas is 90-95 %, and that formed as a result of combustion of the organic sulfur compounds is 5-10 %, even if they are completely transformed into the sulfur dioxide. It has been concluded that it is legitimate to calculate the volume of sulfur dioxide emissions based on the concentration of hydrogen sulfide in purified coke oven gas, supplied as an energy carrier to the heating system of coke ovens.
