FORECASTING THE GROUNDWATER TREATMENT PROCESS IN A BIOREACTOR USING FERROBACTERIA
Authors: Kvartenko Oleksandr , Prysiazhniuk Igor
Published: December 2021

The monitoring of water quality parameters in 90 settlements of eight regions of Ukraine made it possible to state that groundwater is a complex multicomponent system. Existing deironing stations using simplified aeration-filtration technology are not able to remove Fe (II) compounds from water in the presence of humic complexes. Therefore, in modern conditions, the urgent task is to intensify their work through the introduction of new technologies, including biotechnology with the development of appropriate mathematical models. It is shown that much less attention was paid to modeling the kinetics of groundwater treatment processes in bioreactors than to traditional physicochemical methods, for which modern mathematical models were developed.

The aim of the work is to develop a mathematical model of the kinetics of the process of groundwater treatment in bioreactors. The mathematical model is represented by the Cauchy problem for a nonlinear system of differential equations in partial derivatives of the first order. The system of the Cauchy problem consists of five equations with five unknown functions, which describe the distribution the concentration of ferrum cations, bacteria and the matrix structures in two phases (movable and immobilized) both in space and time. The inverse influence of the characteristics of the process, in particular, the concentration of matrix structures in the inter-pore space, as well as characteristics of the medium with the help of coefficients of mass exchange and porosity, were taken into account. The model allows determining the optimum operation time of a bioreactor between washings

Published: December 2021

Issues related to the prospects of implementing the latest technologies aimed at achieving energy efficiency in the field of water supply, resource conservation in material-intensive processes at industrial enterprises and prevention of environmental pollution are considered. A study of ferritative wastewater treatment from chromium compounds, which belong to the first class of danger. The efficiency of thermal and electromagnetic pulse activation of the process is compared. Appropriate experimental setups were developed and the main parameters of the purification process were studied and determined: the ratio of iron (II) and chromium (VI) ions, magnetic field strength, frequency of electromagnetic pulses, ferritization process duration, temperature and pH of the reaction mixture.

The expediency of using electromagnetic pulse activation of the reaction mixture by passing electromagnetic pulses through the reaction mixture has been studied and scientifically substantiated. Rational values ​​of the strength and frequency of the electromagnetic field when using this method of activation, which are 0.01 - 0.14 Tl and 1 Hz, respectively, as well as the ratio of concentrations of heavy metal ions Fe2 + / Cr6 + = 10/1 for washing water chrome plating line . It is shown that purified water meets the requirements of category 1 when reused in production. The results of X-ray diffraction analysis of ferritization sediments showed that stable crystalline phases, such as chromium ferrites and magnetite, are formed with increasing magnetic field strength. The chemical resistance of sludge allows them to be safely disposed of. It is established that this method of electromagnetic pulse activation is not inferior to thermal, and the technical and economic calculations confirmed a significant reduction in industrial costs in its application

Presented a new approach to the training future teachers, including Science (biology, botany, etc.) through the prism of the rose named after the last pharaoh of Egypt, Queen Cleopatra. The authors consider the Cleopatra rose not through the preparation of a plant in the laboratory (while scientific botanists search to know flowers physiologically and morphologically in the spirit of progress and truth,), but reveal the secrets and magic of the Cleopatra rose through the knowledge of "life truths", thus forming professionally oriented foreign language educational space at university (foreign language, history, geography, philosophy, chemistry, art (A.S. Arensky's ballet "Egyptian Nights", operas "Cléopâtre" by Massenet and "Giulio Cesare in Egitto" by Haendel), cinema, literature, psychology), involving students in romantic love, the ability to understand the flower codes inherent in the Cleopatra rose. We use floral codes strategically in their fiction as subtexts for practitioners of the language of flowers. Key words: Queen Cleopatra, rose Cleopatra,

Assessment of the knowledge of nutritional recommendations and way of nutrition in vegetarians and vegans
Authors: Marciniak Sandra , Lange Ewa , Laskowski Wacław
Published: December 2021

Background. People following a vegetarian diet can obtain all the essential nutrients from a variety of foods. Among the nutrients, protein, iron, calcium, zinc, and vitamins B12 and D3 require special attention.
Objective. To assess the knowledge of dietary recommendations among different groups of vegetarians and the diet they follow.
Material and methods. The study involved a total of 390 subjects (360 women and 30 men), aged 18–60 years, who were following different vegetarian diets. The study was conducted in November 2020 via Facebook using the Computerassisted web interviewing (CAWI) method. Participation in the study was voluntary and anonymous, and sample selection was intentional (participants were members of groups for vegetarians in Facebook). Statistical analysis was carried out using the Chi2 test, using Statistica 13.3 (at p=0.05).
Results. To develop the results, the respondents were divided into 4 groups according to their diet: vegan, pescovegetarian, lactovegetarian, and people following other types of diets. The body mass index of nearly 2/3 of the respondents was within the normal range, and more than 80% of the respondents rated their health as good or very good. An analysis of the frequency of consumption of food products showed that, regardless of the type of vegetarian diet they followed, the participants adhered to the principles of proper nutrition. The respondents who rated their nutritional knowledge as very good were more likely to consume vegetables, fruits, legumes, and whole-grain cereals, and rarely consumed sweet and salty snacks, alcoholic and energizing drinks, or fast food. Vegans more frequently consumed fruits, vegetables, legumes, vegetable fats, and vegetable substitutes for meat and dairy products compared to other vegetarians. In addition to plant products, pesco- and lactovegetarians included selected animal-derived products in their food rations, thus skillfully diversifying the diet. More than 80% of the vegetarians used dietary supplements, mainly vitamins D and B12.
Conclusions. Regardless of the type of vegetarian diet followed, the participants seemed to be aware of how to balance their diet and the ingredients that should be supplemented, even though a vast majority of them did not consult a diet specialist.

Published: December 2021

Background. Fruit and fruit products are important part of our daily diet. In addition to the ingredients necessary for the proper functioning of the body, these products can also be a source of intake elements harmful to human health.
Objective. Analysis of the results of monitoring studies conducted in Poland in 2015 concerning contamination of lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg) and tin (Sn) in fruit and fruit products and exposure assessment.
Material and methods. Approximately 600 samples of fresh, frozen, dried fruits, fruit preserves and canned fruits were tested. The laboratories of State Sanitary Inspection were involved in testing. Accredited and validated analytical methods were used. The test samples were prepared in accordance with the standard PN-EN 13804:2013. The contents of lead, cadmium and tin were determined by using flame atomic absorption spectrometry (FAAS) or flameless with electrothermal atomization spectrometry (GFAAS); arsenic by using hydride generation atomic absorption spectrometry method (HGAAS) and mercury the "cold vapor" atomic absorption spectrometry (CVAAS) method.
Results. Contamination of investigated samples with elements harmful to human health (Pb, Ca, As, Hg and Sn does not rise concern to human health and was in most cases comparable with contamination reported in other European Union countries. The estimated average exposure of adults and children to lead intake with fruit and fruit products ranged from 0.5% to 14.6% of the respective Benchmark Dose Lower Confidence Limit (BMDL) established by the European Food Safety Authority (EFSA). The mean intake of cadmium with these groups of foodstuffs was in the range 0.3 - 8.5% of the TWI value (Tolerable Weekly Intake) established by EFSA for adults and children (0.1 - 3.6% of the PTMI (Provisional Tolerable Monthly Intake) established by JECFA. In case of arsenic mean intake was in the range 0.5 - 1.6% BMDL whilst for mercury (inorganic form) intake represented 0.5 - 1.4% of TWI value established by JECFA and then confirmed by EFSA.
Conclusions. Based on the obtained results, it was found that content of Pb, Cd, As, Hg and Sn in the tested samples of fruit and their products does not pose a risk to consumer health. Estimated exposure of consumers does not exceed tolerable doses established by EFSA and JECFA for these elements.

U radu se obrađuje jedan stari, ali još uvijek aktualni, problem dijeljenja jednakostraničnog trokuta na najmanji broj dijelova tako da se preslagivanjem nastalih dijelova, bez preokretanja, može oblikovati kvadrat. Problem je poznat pod nazivom Haberdasherov problem, ali unatoč brojnim pokušajima, jedino do danas poznato valjano rješenje dao je engleski matematičar Dudeney, još 1903. godine. Uz opis konstrukcije i opravdanja valjanosti Dudeneyjeva rješenja, posebno se razmatra jedno rješenje koje pokazalo pogrešnim, a zapravo se radi samo o dobroj aproksimaciji kvadrata. Također, razmatra se klasa rješenja dijeljenja trokuta na dijelove koji se daju oblikovati u pravokutnik među kojima je i jedan kvadrat. Konačno, navode se i razlozi zašto su ovakvi i slični problemi korisni i prikladni za korištenje na svim razinama obrazovanja.
Brazilian illegal gold miners resilience in French Guiana: The garimpo as an economic and social system
Authors: Le Tourneau François-Michel
Published: December 2021

Artisanal small-scale gold mining, or garimpo in Portuguese, started in French Guiana in the 1990s. The French authorities have repressed it, but this has not led to the end of the activity. Based on extensive fieldwork, this paper aims to analyze the garimpo as an economic and social informal world built to be resilient to repression and to neutralize the high risks of clandestine exploitation. This system provides economic, social, and moral resources, all embodied in the garimpeiro identity, allowing a workforce made of thousands of individuals to act as a cohesive work organization.Resumen: Resiliencia de los mineros de oro ilegales brasileños en la Guayana Francesa: El garimpo como sistema económico y social La minería de oro artesanal a pequeña escala, o garimpo en portugués, comenzó en la Guayana Francesa en la década de 1990. Las autoridades francesas lo han reprimido, pero no ha supuesto el fin de la actividad. Basado en un extenso trabajo de campo, este artículo tiene como objetivo analizar al garimpo como un mundo económico y social informal construido para ser resistente a la represión y neutralizar los altos riesgos de la explotación clandestina. Este sistema proporciona recursos económicos, sociales y morales, todos encarnados en la identidad garimpeiro, permitiendo que una fuerza de trabajo compuesta por miles de indivi-duos actúe como una organización de trabajo cohesiva.

Published: December 2021

Abstract: Covid-19 and short food supply circuits in Argentina: The role of social actorsThe aim of this article is to analyze how the actors participating in short food supply circuits reconstructed their practices in the context of the pandemic in Argentina. Based on the analysis of experiences in different geographical areas, heterogeneous processes were identified. This diversity is related to agroecological characteristics, population density, and the level of resources of producers and consumers, among other factors. The pandemic has increased the sales based on geographical proximity in several of the cases analyzed; in others, particularly those linked to tourism, it led to the search of alternatives based on new networks and/or the strengthening of previous ones, using virtual connections that were enhanced in the situation studied. This reconfiguration is associated with a redefinition of the actors involved in short food supply circuits, especially the strengthening of hybrid intermediaries. ResumenEl objetivo del artículo es analizar cómo los actores participantes de los circuitos cortos de comercialización de alimentos reconstruyeron sus prácticas en el contexto de la pandemia en la Argentina. A partir del análisis de experiencias relevadas en diferentes áreas geográficas, se identificaron procesos heterogéneos vinculados, entre otros factores, con características agroecológicas, densidad poblacional y el nivel de recursos de productores y consumidores. La pandemia acentuó las ventas basadas en la proximidad geográfica en varios de los casos analizados; en otros, particularmente los ligados al turismo, condujo a la búsqueda de alternativas a partir de nuevos vínculos y/o el reforzamiento de previos, apelando a conexiones virtuales que se potenciaron en la coyuntura estudiada. Esta reconfiguración está conectada con una redefinición de los actores participantes en circuitos cortos de comercialización, en particular la consolidación de intermediarios híbridos.

Legal Protection for Indonesian Freelance Workers in Law Number 11 of 2020 Concerning Work Creation: Analysis of Changes in Legal Protection for Freelance Workers in Indonesia after the Omnibus Law
Authors: M. Muhsin
Published: December 2021

This research aims to review the legal protection for freelancers in Indonesia, stipulated in Law Number 11 of 2020 concerning Job Creation. In-Law no. 13 of 2003 concerning Freelance Employment in Indonesia is claimed not to have a clear legal umbrella. The problems examined in this research include the form of freelance legal relations in Indonesia? And the legal protection for freelancers in Indonesia in Law Number 11 of 2020 concerning Job Creation? This research uses normative methods with a statute, case, and historical approach. The results showed that freelance legal relationships in Indonesia were divided into two categories: freelancers who entered into work agreements through platforms that acted as intermediaries and freelancers who entered into work agreements directly without intermediaries. Previously, there were only additional regulations in the form of Kepmenakertrans No. 100 of 2004 concerning the Provisions for the Implementation of a Work Agreement for a Specific Time, and no specific regulation has been found in Law no. 13 of 2013 concerning Manpower. After the enactment of Law Number 11 of 2020 concerning Job Creation and also Government Regulation No. 35 of 2021 concerning Specific Time Work Agreements, Transfer, Working Time and Rest Time, and Termination of Employment, the legal status of freelance workers in Indonesia has a clear legal umbrella, which is classified as a specific time work agreement (PKWT). This finding also answers the concerns of previous researchers who stated that there is no legal protection for freelancers in Indonesia.

Published: December 2021

Mycoplasma hominis is associated with various infections, for which the treatment can be complex. Lipoic acid (LA) plays a role as a cofactor in eukaryotes, most Bacteria, and some Archea. Research of recent years has increasingly pointed to the therapeutic properties of exogenously supplemented LA. The present study was conducted on 40 strains of M. hominis cultured with the following LA concentrations: 1,200 μg/ml, 120 μg/ml, and 12 μg/ml. The bacterial colonies of each strain were counted and expressed as the number of colony-forming units/ml (CFU). The number of CFU in M. hominis strains obtained in the presence of LA was compared with the number of CFU in the strains grown in the media without LA. The obtained results indicated that the presence of LA in the medium did not affect the growth of M. hominis. The investigation of the influence of LA on the growth and survival of microbial cells not only allows for obtaining an answer to the question of whether LA has antimicrobial activity and, therefore, can be used as a drug supporting the treatment of patients infected with a given pathogenic microorganism. Such studies are also crucial for a better understanding of LA metabolism in the microbial cells, which is also important for the search for new antimicrobial drugs. This research is, therefore, an introduction to such further studies.

Unearthing St. Edmund: A source for Edmund's martyrdom in Íslendingabók
Authors: Allport Ben
Published: December 2021

In Ari fróði Þorgilsson’s Íslendingabók, the settlement of Iceland is said to have first begun from Norway in 870, the year that “Ívarr, son of Ragnarr loðbrók, had St Edmund, king of the English, killed.” He attributes his knowledge of the date of this martyrdom to a mysterious “saga” of St Edmund, the identity of which has long been debated. This note considers the various alternatives put forth by previous researchers and concludes that the most likely candidate for this saga is in fact a composite of two texts, Abbo of Fleury’s Passio Sancti Eadmundi and Hermannus the Archdeacon’s De miraculis Sancti Eadmundi. These texts are known to have been bound together in at least one manuscript from the early twelfth century. It is argued that a similar manuscript may have circulated in Iceland and was used to inform several other Old Icelandic texts composed over the following two centuries.

En fædrene forbindelse?: Om sammenhængen mellem de fire Hrafnistumannasögur
Authors: Ellyton Pernille
Published: December 2021

This article explores the connection between the four legendary sagas collectively known as the Hrafnistumannasögur. Through analysis of their entire manuscript transmission it is investigated how the saga group is transmitted historically, and it is argued that the 15th century manuscript AM 343 a 4to has had a significant impact on the reception of the sagas as a group. An analysis of literary elements and parallels between the sagas reveals substantial differences in genre, themes, and literary style, which appears to contradict the idea that the group was originally connected. The article argues that the Hrafnistumannasögur cannot without hesitation be treated as a group, and it is proposed that the sagas have been grouped together in some manuscripts not due to inherent thematic parallels but because of historical and cultural circumstances that favored the genealogical ties between saga heroes. It is argued that the connection, however fragmentary and instable, was formed initially between Ketils saga hængs and Gríms saga loðinkinna, after which these sagas were grouped with Örvar-Odds saga. Finally, Áns saga bogsveigis was added to the group, and it is hypothesized, that this last connection presumably happened around the time of the writing of the important manuscript AM 343 a 4to (ca. 1450–75).
Tvær dæmisögur Esóps og latnesk skrifaravers í formála Adonias sögu og tengsl þeirra við latínubrotin í Þjms frag 103,104 og AM 732 b 4to
Authors: Jensson Gottskálk
Published: December 2021

The author of this article conclusively traces the source of the two Aesopic fables retold in the prologue to Adonias saga to the medieval collection of Latin fables known as Anonymus Neveleti (alias Romulus elegiacus), fragments of which are preserved in two Icelandic vellum bifolia (Þjms frag 103 and 104) that probably originate from the Benedictines monastic houses of North Iceland. In a review of various ancient and medieval collections of Aesop’s fables, the author concludes that the unknown Icelandic author of Adonias saga must have been familiar with the two fables in this particular Latin version, even though his Icelandic rendering of them is free and likely based on memory. A parallel to a Latin couplet cited in the prologue is furthermore identified in a bilingual encyclopædic manuscript, AM 732 b 4to, also associated with the northern Benedictines. The author of the article suggests the possibility that the incorporation of two Aesopic fables in the prologue to Adonias saga, a riddarasaga, is an indication that such sagas ought to be interpreted like fables, that is not only read as entertainment but also as ethical instruction.

В работе предложена новая структурно-феноменологическая реологическая модель, которую можно рекомендовать для инженерных расчетов течений растворов и расплавов полимеров. Тензор дополнительных напряжений содержит два слагаемых: стационарный вклад и тензор возмущений. Простота и надежность реологической модели обусловлены линейным характером уравнения для тензора возмущений, которое получено исходя из модифицированной модели Виноградова-Покровского. Расчет стационарного вклада предложено проводить по аппроксимационным выражениям, содержащим неизвестные функции. Для определения этих функций используется условие адекватности моделирования стационарных вискозиметрических течений. На основе полученной модели были рассчитаны стационарные вискозиметрические функции при простом сдвиге и одноосном растяжении, а также были выполнены расчеты напорного или Пуазейлевского течения полимерной жидкости в каналах с параллельными стенками под действием постоянного перепада давления. Показано, что модель с хорошей точностью описывает нелинейное вязкоупругое поведение текучих полимерных систем. Проведено сравнение с экспериментальными данными для расплава промышленного образца полиэтилена.

Однако расширение в первую очередь транспортной инфраструктуры, а в рамках рассматриваемой проблемы в первую очередь метрополитена, в рамках уже существующей застройки в современных городах не позволяет расположить тоннели и железнодорожные полотна на таком расстоянии от жилых домов и офисных зданий, что бы отрицательное влияния вибраций от движущегося транспорта было минимальным. Решение проблемы защиты от различной степени интенсивности вибраций, возникающих как по естественным, так и техногенным причинам, ищется уже достаточно давно. И на данный момент существуют различные способы понижения уровня вибраций в грунте, разной степени эффективности.

Адаптер полезной нагрузки ракеты космического назначения представляет собой переходный отсек с формой, отличной от цилиндрической, и предназначен для размещения одной полезной нагрузки для вывода её на целевую орбиту. В настоящий момент в отечественной практике применяются адаптеры слабоконической, конической и цилиндрической форм, позволяющие переходить от интерфейса разгонного блока (РБ) космической головной части (КГЧ) к интерфейсу космического аппарата или платформы с размещёнными космическими аппаратами (КА). На такой платформе, как правило, должны обязательно быть размещены вспомогательные устройства отделения для каждой из выводимых полезных нагрузок (ПН).

Представлены результаты расчетов обтекания двух тел, расположенных вдоль направления потока. Известны результаты экспериментальных исследований аэродинамических характеристик системы груз - тормозное устройство. Одним из интересных явлений в данной задаче является гистерезис характеристик при изменении расстояния между телами. Фактически, реализуемая схема обтекания зависит не только от величины расстояния, но и от режима обтекания, в котором система находилось до изменения расстояния. Показана возможность численного моделирования этого явления.

В настоящей работе построена аналитическая механическая модель эжекции, возникающей при высокоскоростном ударе жесткого ударника по полубесконечной преграде, и дана оценка массы эжекции и эффекта усиления импульса, передаваемого при ударе. Модель построена в приближении плоской деформации с использованием минимального числа параметров материалов ударника и преграды. Получены уравнения для массы эжекции и приращения импульса преграды, в зависимости от глубины внедрения ударника. Модель учитывает зависимость угла вылета эжекционных фрагментов от глубины внедрения ударника.

Моделирование взаимодействия инженерных сооружений с грунтом - нетривиальная задача, постоянно возникающая при проектировании транспортных сооружений. Упрощение расчётной схемы с использованием гипотез теории упругости далеко не всегда даёт правильные результаты. Поэтому для уточнения расчётных моделей необходимо учитывать нелинейную работу грунта с использованием различных алгоритмов теории пластичности и механики грунтов. Авторами был разработан программный модуль для определения напряжённо-деформированного состояния грунтового массива с учётом физической нелинейности. В работе приведены результаты сравнительного анализа расчётов грунтовых сред в линейной и нелинейной постановке при различных градиентах густоты сетки.

YENİ MECMUA’DA YAYIMLANAN BİR MİLLİ MÜCADELE HATIRATI ÜZERİNE
Authors: OĞUZ İsmail
Published: December 2021

Kemal Balıkesir, 1888 yılında Balıkesir'in Martlı mahallesinde, Amasyalı Yüzbaşı Hafız Ömer Efendi ile Balıkesir'in Tepecik Köyü'nden Müveddet Hanım'ın oğlu olarak dünyaya geldi. İlkokulu Balıkesir'de tamamladıktan sonra eğitimine İstanbul'da devam etti. Sırasıyla Eyüp Askeri Ortaokulu, Kuleli Askeri Hazırlık Okulu, İstanbul Harp Okulu ve Harp Akademisi'nden mezun oldu. Balıkesir’in yönetiminde bulunmuş ve orduya pek çok asker yetiştirmiş, aslen Türkmen kökenli Cebbâr-zade ailesine mensup olan Kemal Balıkesir, bir asker olarak Milli Mücadele yıllarında, Kuzeybatı Anadolu Kuvâ-yı Milliyesi içerisinde gönüllü olarak yer almış milli mücahittir. O, asker olmasına karşın gerektiğinde sivil halktan müfrezeler oluşturup başarılı askeri harekatlar yapmıştır. Balıkesir’in milli mücadele önderlerinden olan Kemal Bey, milli mücadeleye ilk katıldığı andan itibaren yaşadıklarını, yaptıklarını kaydetmiştir. İstiklal Savaşı’ndan sonra bu hatıralarını yeni kurulmakta olan Cumhuriyet rejimini desteklemiş ve karşısında olanları eleştirmiş bir dergi olan Yeni Mecmua’da yayımlatmıştır. Hatıralar, derginin yayın hayatının ani olarak sona ermesi nedeniyle Kemal Balıkesir’in tüm hayatını ihtiva etmemekte, 1919 yılının bir bölümünü kapsamaktadır. Ancak hatıralar, olayların tanığı olan kişiden ilk elden bilgiler vermesi ve günümüze değin bir şekilde kullanılmamış olması nedenleriyle fevkalade önemlidir. Bu çalışma, İSAM veri tabanında yer alan Yeni Mecmua’da yer alan anıların bugüne kadar yayınlanan çalışmalarda bahsedilmediği gerçeğinden yola çıkılarak hazırlanmıştır. Ayrıca yerel tarih ve sözlü tarih çalışmaları yoluyla bilgi toplamak, bireylerin yaşam öykülerini daha bilimsel ve zenginleştireceği için Kemal Balıkesir'in hayatı hakkında bilgi toplarken birinci derece akrabalarla da görüşülerek veri toplandı. Kemal Balıkesir ile ilgili yayınlarda, özellikle Kurtuluş Savaşı ile ilgili anıların olaylardan yaklaşık yarım asır veya daha sonra yayınlandığı görülmektedir. Bu noktada İSAM veri tabanında yer alan dergide yer alan anılar, 1923 gibi olayların zamanına oldukça yakın bir tarihte yayınlandığı ve olayın tanıklarının büyük çoğunluğunun hala hayatta olduğu zamanlarda yayınlandığı için büyük önem taşıyor. Araştırma-inceleme yönteminin kullanıldığı çalışma; Giriş, Hatırat, Kemal Balıkesir, Yeni Mecmua, Yeni Mecmua’da Kemal Bey’in Milli Mücadele Hatıraları ve Sonuç başlıklarından oluşmuştur.
Interference of state authorities in the internal affairs of religious organisations in 1917–1928 (on the example of Orthodoxy and Protestantism)
Authors: Yanushevich Ivan I.
Published: December 2021

Using the example of the Orthodox and Protestant churches, the process of interference by state authorities in the internal affairs of religious organisations in 1917–1928 is considered. The mechanisms of influence on believers, clergy and the leadership of these structures are analysed. It is determined that the main pressure was exerted to obtain, including public, support for all decisions of state bodies concerning domestic and foreign policy. It is established that the authorities planned to reduce the number of parishioners of the canonical Russian Orthodox Church by granting preferences to other confessions and religious movements, as well as its fragmentation by inspiring schisms. An attempt to transfer the management of the Orthodox Church formed by state bodies in a group of clergy in a non-canonical way has been studied.

Published: December 2021

The article is of an overview nature and contains up-to-date information on comorbid cardiovascular pathology in psoriasis. Various studies have shown that psoriasis is associated with a higher prevalence of CVD risk factors, including hypertension, diabetes mellitus, dyslipidemia, obesity, and metabolic syndrome. The relationship between the severity of psoriasis and the risk of cardiovascular disease, as well as the prognostic risks with mortality rates, are discussed. Proposed common pathogenetic mechanisms include genetic factors, inflammatory pathways, adipokine secretion, insulin resistance, lipoprotein composition and function, angiogenesis, oxidative stress, and hypercoagulability.
Do Individual Factors Matter? Examining Auditor Judgement Bias and Public Accounting Firm Size
Authors: Caesar Marga Putri  , Asti Putri Pratiwi
Published: December 2021

Auditor personality is a topic of interest within the accounting field due to the scarcity of research on accountant personalities in Indonesia. This research aimed to examine the moderating effect of public accounting firm size, personality traits and locus of control on the correlation between role conflict and auditor judgement bias. The sample comprises auditors who work at public accounting firms in Java province and the study uses regression analysis as its method of analysis. The result shows that only internal locus of control has a significant moderating effect on the relationship between role conflict and auditor judgement bias. This indicates that auditor personality and public accounting firm size do not affect auditors’ professionalism in making judgements.

Smoking is an alarming public health issue in today’s rapidly urbanising society. The objective of the present study is to investigate factors associated with the demand for cigarettes among adults in Malaysia, i.e., an ASEAN country. Statistical analyses were performed using nationally representative data with a large sample. In terms of multivariate analysis, a Tobit model was used to examine the effects of sociodemographic factors on expenditure on cigarettes. Both conditional and unconditional expectations were estimated. We found that age, gender, wealth index, education and house locality were significantly associated with expenditure on cigarettes. The elderly spent less on cigarettes compared with young adults. Males and less-educated individuals spent more on cigarettes than females and well-educated individuals. There was a positive relationship between residing in urban areas and cigarettes expenditure. In conclusion, sociodemographic factors play an important role in determining the demand for cigarettes. Findings of the present study show that a successful anti-smoking policy should be targeted primarily at individuals who spend a large amount of money on cigarettes.
