Authors: Barros Sevillano Shamir , Arias Flores Loana , Castañeda Jiménez César Abel
Published: March 2021

Sr. Editor:La alarmante situación respecto a la conducta suicida no es indiferente en los estudiantes de medicina, es un tema de interés para evaluar el estado mental y emocional de los estudiantes que están expuestos a un sin fin de perturbaciones mentales propias de la exigencia de la carrera, así como las obligaciones propias de una vida expuesta a diferentes estímulos, en su mayoría negativos, que influyen en su manera de pensar, sentir y actuar. La conducta suicida es una condición clínica que contempla varias etapas: deseos de morir, ideación o pensamiento suicida, plan suicida, intento suicida y suicidio concluido. 1 La prevalencia de pensamiento suicida en los estudiantes de medicina a nivel global llega hasta un 53,6 %. 2 En el Perú se conoce que un 22 % de estudiantes de medicina presenta ideación suicida y un 11 % intentó suicidarse en algún momento de la carrera, lo que representa valores más altos que los hallados en la población en general. 3

Icing Load and Risk Forecasting for Power Transmission Line Based on Multi-scale Time Series Phase-Space Reconstruction and Regression
Authors: Chen Yong , Li Peng , Wang Huan , Ren Wenping , Cao Min
Published: March 2021

Accurately forecasting the icing load on overhead power transmission lines is an important issue to ensure the security and reliability of the power grid. A multi-scale time series phase-space reconstruction and regression model for icing load prediction is proposed in this paper to treat the non-stationary, nonlinear, and intermittent volatility of power line icing load data. Those is motivated by the traditional icing load prediction models having many disadvantages in the forecasting accuracy, as well as the casualness of the parameters selected. Firstly, the icing load data are decomposed into a multi-scale time series of intrinsic model function (IMF) components with stability by using the ensemble empirical mode decomposition (EEMD), which can reduce the interactions between different types of feature information. Secondly, phase-space reconstruction (PSR) theory is applied using the mutual information and the false nearest neighbor to determine the optimal delay time and embedding dimension of each IMF component. Thirdly, considering the characteristics of each IMF component, different kernel functions and optimization parameters are selected to establish the prediction model based support vector regression (SVR). Finally, according to the load prediction results, fuzzy reasoning method was used to determine the risk status of transmission line towers in this paper. Upon experimentally evaluating the validity of the model using related transmission lines of the Yunnan Power Grid, it is shown that this method could predict the real-time icing load on overhead power lines, obtaining better regression performance. This model could be used on power transmission and distribution systems for deicing and maintenance decisions.
Theatre as Church Service: Brat Magarac (“Brother Donkey”)—A Drama about Saint Francis of Assisi by the Croatian Author and Director René Medvešek and its Staging at ZKM Zagreb

Teatr jako nabożeństwo: Brat Magarac (“Brat Osioł”) — dramat o św. Franciszku z Asyżu chorwackego dramaturga i reżysera René Medveška i jego scena w ZKM w Zagrzebiu

Artykuł dotyczy dramatu Brat Magarac („Brat Osioł”) chorwackiego dramaturga i reżysera René Medveška oraz inscenizacji autorskiej w Teatrze Młodych (ZKM) w Zagrzebiu w 2001 r. Dramat przedstawia życie Franciszka z Asyżu. Liczne produkcje filmowe na ten temat świadczą o teatralności nieodłącznej od życia św. Franciszka. Inscenizacja Medveška odpowiada nauczaniu św. Franciszka, ponieważ dekoracje i kostiumy są bardzo skromne. Dodatkowo, integrując elementy muzyczne, całość nabiera walorów liturgicznych. Odpowiada to w ogólności wyobrażeniom autora o teatrze, który jego zdaniem nie ogranicza się tylko do przedstawienia dla widowni, ale – podobnie jak nabożeństwo – łączy ludzi i umożliwia im przeżycie katharsis.
Evaluation of the Cost-Effectiveness of Virtual and Traditional Education Models in Higher Education: A Systematic Review
Authors: Pakdaman Mohsen , Nazari Moghadam Maryam , Dehghan Hamid Reza , Dehghani Arezoo , Namayandeh Mahdieh
Published: March 2021

Context: Recent advances in information technology and electronic devices, as well as limitations in traditional education, have persuaded higher education systems to use the virtual model as an alternative. The present systematic review aimed at evaluating the cost-effectiveness of both the traditional and virtual education models.
Methods: In this systematic review, articles published in known English and Persian databases, such as MEDLINE (PubMed), Scopus, Science Direct, HTA, Cochrane, Irandoc, Magiran, and SID from 2007 to 2017 were retrieved. Studies on health technologies and economic were also reviewed. For this purpose, the hierarchical search algorithm and the keywords “e-Learning” and “traditional education” were used.
Results: Ten studies were included, and their results were slightly different. Most studies showed that the cost-effectiveness of virtual education alone or in combination with traditional education (blended model) was equal or greater than that of traditional education. The data analysis of the articles was performed by comparing cost, effectiveness (Min, SD, QASE), cost-effectiveness (ICER), and the average cost per student. Cost-effectiveness refers to achieve the highest output at the lowest cost. The results showed that due to the use of multimedia, lack of space and time limitations, admission of a large number of students, the increased student satisfaction, easy and fast access to information, and use of Sharable Content Object Reference model in producing content and instruction, distance higher education reduces education costs while compensating for the lack of human resources in the teaching-learning process.
Conclusion: One of the effective methods in the education of medical students seems to be Web-based teaching as traditional teaching. Considering the predominance of the web-based method, it is recommended to be used in educational programs in the universities.

Published: March 2021

Introduction: With the alternation of the educational system from a three-stage into a two-stage system in Iranian schools since several years ago, five-year-old children entered from kindergartens to primary schools. This study was conducted to investigate the harmonization of classroom furniture with anthropometric dimensions in preschool students. 
Methods: In this cross-sectional study, 366 male and female preschool students were selected by cluster sampling method in Kerman, Iran.  Some of the anthropometric dimensions such as shoulder, elbow, and popliteal height, popliteal buttock length, and buttock breadth were measured. mean, maximum, minimum, standard division, and 5th, 50th, and 95th percentiles were calculated for both the sexes and were compared with five dimensions of the existing seats. Next, the dimensions of the standard seats were determined according to the anthropometric dimension’s students. Data were analyzed using SPSS 21 .
Results: Independent-Samples T-test between girl and boy pre- school students in Kerman city showed just popliteal height had a siginificnt diference (p ≤0.05). Match of antropometric musurmants with seat dimentions indicated that there is no consistency between the seats and anthropometric dimensions in. Armrest height, seat height, backrest height, seat depth and seat breadth were matched with (0, 0.5, 10, 6.7, 0) and (0.7, 28.7, 6, 2.5, 0) percent of anthropometric musurments of girl and boy students respectively
Conclusions: Due to adding a new grade to primary school, it seems that no work has been done for improving the furniture. Therefore, in this article, we presented the dimensions of an appropriate seat. This may help not only save production costs in the industry but also increase the matching between students' anthropometric and seat dimensions.

The Need for Multi-Sectoral Partnerships in the Healthcare of Islamic Developing Countries During the Coronavirus Pandemic
Authors: Motamedi Mahdieh , Vaezi Reza , Alvani Seyed Mehdi , Danesh Jafari Davood
Published: March 2021

Nowadays, the field of healthcare is facing difficult issues in a way that both public and private sectors are fully aware of their inability to address emerging public health-related issues without the help of the other sector. Accordingly, public-private partnerships are put on the agenda in policy-related issues as a mechanism of cooperation between the public and private sectors to take into account the interests of both parties in the related contracts .From the late of 2019, the world is struggling with a new virus called the coronavirus, which has already cost a lot to the health sector. The partnership between the government and the private sector is very important to get through the corona period since the government alone cannot be responsible for the negative effects of the virus in the field of health. Considering the successes and failures of countries in the implementation of partnership models, a question arises as to how such partnerships for health development strategies can be attractive and effective in developing Islamic countries. In addition to the review of theoretical foundations of the subject and examining the development process of public-private partnerships, the study emphasizes the use of the third sector capacities. It further reviews the endowments and charitable affairs in the framework of multi-sectoral partnerships to develop health in the community with all available potentiality. The theoretical framework of the research includes the four steps of policy-making in the country, creating common perspectives among stakeholders, ensuring key success factors in the project, and reviewing the achievements of participation are considered. These policies are described after classifying and reconstructing the components in the research literature.

Background: Charcot-Marie-Tooth disease (CMT) is a heterogeneous group of disorders best known for causing inherited forms of peripheral neuropathy. History of CMT disease is not considered relevant in patients presenting with acute central neurologic manifestations of acute stroke. The case described here should alert clinicians to the possibility of transient stroke-like episodes in young patients suffering from CMTX1, X‐linked variant of CMT.

Case description: A 21-year-old man presented to our emergency department with acute onset dysarthria, right facial weakness and right hemiparesis, which started 2 hours before his admission. He was treated with intravenous thrombolysis with a suspected diagnosis of acute ischemic stroke with full resolution of symptoms. The following day he experienced another stroke-like episode of acute onset of dysarthria and left facial weakness that resolved within 3 hours. The patient underwent stroke in the young work-up which was normal. MRI of the brain showed symmetric, non-enhancing areas of restricted diffusion in the corona radiata bilaterally and corpus callosum, also demonstrated on T2/fluid-attenuated inversion recovery (FLAIR) sequences. Clinical and familial investigations resulted in diagnosing CMTX1, X‐linked variant of CMT.

Discussion: This case illustrates that CMTX1 disease can have central nervous system (CNS) manifestations that could mimic stroke-like neurological deficits with pathological MRI findings. The prognosis of the CNS phenotype of CMTX1 is usually good, with spontaneous resolution without
Herod’s golden eagle on the Temple gate: a reconsideration
Authors: Bourgel Jonathan
Published: March 2021

Flavius Josephus reports that Herod the Great erected a golden eagle over the great gate of the Jerusalem Temple (
JW
1:648–55;
Ant
17:149–63). Sometime before his death, two doctors of the law convinced their disciples to pull the eagle down, for it ‘had been erected in defiance of their fathers’ laws’. Eventually, they were arrested and sentenced to be burned alive by Herod. This account is often taken to reflect Herod’s impious attitudes towards Jewish law, on the one hand, and his unfailing loyalty to the Romans, on the other, the golden eagle supposedly being a symbol of Roman power. However, a careful reading of this account does raise questions serious enough to reconsider its historicity. The present article proposes that the episode of the golden eagle is a martyrdom narrative conveying a legend.
Defective spelling in manuscripts of the Mishnah: a proposed explanation
Authors: Henshke Yehudit
Published: March 2021

This article reconsiders the explanation for the defective spelling of the long /ō/ vowel in Hebrew in MS Cambridge of the Mishnah and other rabbinic sources in a number of morphological categories: the active participle, plural feminine forms, the suffix
-on
, the numerals
šemonah / šemone
and
šaloš
and their inflected forms, and inflected
’et
. If the prevailing explanation attributes this anomalous defective spelling in Mishnaic Hebrew manuscripts to the influence of defective biblical orthography, the article suggests that another factor should be taken into consideration: the living interlingual contact between Aramaic and Hebrew in the early first millennium. It proposes that the defective spelling of /ō/ reflects the realization of the long /ā/ vowel preserved in Aramaic and that the familiarity of speakers with both phonological alternatives in similar morphological structures facilitated exchanges between them.
Mutual responsibility in Kabbalistic thought – ethics, theology and gender
Authors: Kara-Ivanov Kaniel Ruth
Published: March 2021

This article explores the evolution of the concept of ‘mutual responsibility’ from the biblical and Talmudic eras to medieval Kabbalistic literature, and to analyse the notion of
arvut
and its implications through the prism of gender. I suggest that whereas in the Bible and in rabbinic literature the ‘negative’ aspect of mutual responsibility was emphasized, with a focus on one’s obligation to take responsibility for another’s sins or for his soul, in Kabbalistic literature metaphysical and ‘positive’ aspects of mutual responsibility were developed. I discuss the connection between
arvut
and the doctrine of
gilgul
, and other practices such as the Pilgrimage Festival, which illustrates the metaphysical idea of responsibility.
The representation of spoken Hebrew in Eretz-Israeli fiction  films from the 1930s
Authors: Bar-Ziv Levy Miri
Published: March 2021

This article examines whether the dialogue in the first two full-length Hebrew narrative films reflects spoken Hebrew of the time. The first part examines phenomena that, according to written testimonies in grammar books and prescriptivist writings, were typical of spoken Hebrew during the British Mandate period. It shows that these phenomena were not represented in the films from the 1930s, whereas in later films there is a significant rise in their frequency. The second part examines phenomena that are not typical of spoken speech today but are represented in the dialogue of the films from the 1930s. In later films they become very rare or vanish altogether. An analysis of the findings shows that the film-makers did not regard it as the function of cinematic dialogue to authentically reflect spoken speech, but rather adopted the normative approach to Hebrew, which strongly preferred high-register Hebrew over authentic usage.

Published: March 2021

Актуальность. Это первые геохимические исследования в горнорудном районе Киви. Они необходимы в виду возможного наличия в районе перспективных месторождений титана и цинка. Сложность геологического строения определяет необходимость применения нетрадиционных методов исследования и прогнозирования – искусственных нейронных сетей и методов кластеризации – для оценки поведения химических элементов. Цель заключается в определении геохимического поведения Ti и Zn для прогнозирования новых рудоносных площадей и перспективных участков. Объект: район Киви в провинции Ардебиль, Иран (Иранский Азербайджан), геохимическая карта масштаба 1:100000. Методы. Исходными данными послужили отобранные пробы из донных отложений района Киви, которые были проанализированы методом ICP-MS. Интерпретация геохимических данных проводилась с использованием одномерных и многомерных статистических методов, включая кластеризацию методом K-средних. Содержания Ti также были предсказаны с использованием искусственных нейронных сетей. Результаты. Согласно результатам, полученным в процессе обработки геохимических данных, было составлено уравнение регрессии, которое представляет собой функцию для оценки содержания титана на основе трех параметров: содержания цинка, длины и ширины точек отбора проб, коэффициента корреляции. Согласно результатам исследования, были предсказаны концентрации Ti; коэффициент корреляции между исходными и предсказанными значениями составил 0,51. Метод искусственных нейронных сетей дает более точные данные, чем кластеризация методом К-средних. Были построены схематические карты исходных и предсказанных содержаний Ti. Результаты исследования можно использовать в процессе проведения геологоразведочных работ для прогнозирования и выявления новых перспективных площадей.
ФИЗИКО-ХИМИЧЕСКИЕ ОСОБЕННОСТИ ФЛЮИДОВ, СФОРМИРОВАВШИХ АПОГИПЕРБАЗИТОВЫЕ И АПОКАРБОНАТНЫЕ НЕФРИТЫ

Published: March 2021

Актуальность. В наиболее крупной в России Сибирской нефритоносной провинции обнаружены месторождения двух формационных типов – апогипербазитовый и апокарбонатный. Их тела формируются на контактах серпентинизированных пород и доломитовых мраморов с алюмосиликатными породами. Актуальность работы определяется тем, что установлены факторы, контролирующие единообразие минералогических типов нефритов различного генезиса, – состав гидротермального раствора и Р–Т условия процесса. Цель. Критическое обобщение мирового материала по геохимии и петрологии нефритов позволяет достичь основной цели работы – подготовить исходные данные для формирования модели, адекватно описывающей особенности физико-химических процессов образования как апокарбонатных, так и апогипербазитовых нефритов. Объекты: Кавоктинское месторождение апокарбонатного нефрита и Оспинское месторождение апогипербазитового нефрита. Методы. Представленный химический состав пород определялся фотометрическим, атомно-абсорбционным, потенциометрическим и пламенно-фотометрическим методами, содержание микроэлементов – методом масс-спектрометрии с индуктивно связанной плазмой. Изотопные составы кислорода и углерода проанализированы методом лазерного фторирования, а углерод и кислород в карбонатах – по методике разложения ортофосфорной кислотой. Изотопный состав водорода в гидроксилсодержащих минералах определен по методу Vennemann, O’Neil. Результаты. Мировые данные по геохимии и петрологии нефритов позволили установить, что апогипербазитовые нефриты формировались под воздействием магматических и метаморфических вод из серпентинитов, в апокарбонатных проявлениях нефрита флюид представляет собой метеорные воды, насыщенные углекислотой, образующейся при декарбонатизации доломита. Рассмотрена последовательность образования минеральных парагенезисов при развитии метасоматической зональности на контакте пород различного состава. По минеральному парагенезису апокарбонатный нефрит относится к низкотемпературной фации магнезиальных скарнов (350–400 °C). В результате формируется следующая метасоматическая зональность: доломитовый мрамор – кальцитовый мрамор с нефритом – тремолитовый скарн – пироксен – амфибол – клиноцоизитовый скарн – амфиболиты. Месторождения апогипербазитового нефрита имеют иную метасоматическую зональность: микроантигоритовый серпентинит – тремолитит – нефрит – тремолитит – кварц-диопсид-клиноцоизитовый родингит – цоизит-амфиболовая порода. Температура меняется в интервале 300–450 °C, давление 2000–3000 бар. Эти данные в сочетании с химическим и изотопным составом позволяют построить модель, адекватно описывающую особенности физико-химических процессов образования как апокарбонатных, так и апогипербазитовых нефритов. Следовательно, единообразие минералогических типов нефритов различного генезиса определяется составом гидротермального раствора и Р–Т условиями процесса.

Актуальность исследования обусловлена необходимостью разработки более эффективных технических решений по ограничению перенапряжений, появляющихся при коммутации трансформаторов 6 (10)/0,4 кВ. Цель: изучение влияния компенсации реактивной мощности на величину коммутационных перенапряжений при коммутации силовых трансформаторов 6 (10)/0,4 кВ и обоснование наиболее эффективных средств защиты трансформаторов от коммутационных перенапряжений. Объекты: трансформаторы мощностью 250, 400, 630 и 1000 кВА, вакуумные выключатели, регулируемые конденсаторные установки.  Методы: инструментально-осциллографический, имитационное моделирование переходных процессов фазных напряжений выполнялось в MultiSim. Результаты. Проведен анализ эффективности существующих средств защиты от коммутационных перенапряжений, возникающих при коммутации силовых трансформаторов 6 (10)/0,4 кВ. Выполнено компьютерное моделирование влияния компенсации реактивной мощности на величину коммутационных перенапряжений. Для подтверждения результатов моделирования были выполнены экспериментальные исследования, показаны осциллограммы коммутационных перенапряжений, возникающих при отключении силового трансформатора мощностью 250 кВА. Установлено, что устройства, осуществляющие компенсацию реактивной мощности, эффективно ограничивают перенапряжения, появляющиеся при отключении трансформаторов 6 (10)/0,4 кВ, если данные устройства связаны с обмоткой низкого напряжения.  В городских электрических сетях для эффективной компенсации реактивной мощности предложено использовать конденсаторные установки с пофазной компенсацией и располагать их на вводах муниципальных и жилых зданий, а для ограничения коммутационных перенапряжений внедрять на трансформаторных подстанциях нерегулируемую конденсаторную установку с симметричной компенсацией.
Social justice - the basis of public accord in modern society
Authors: Patsiorkovsky Valery
Published: March 2021

Since the beginning of socio-economic transformations (1991), the state system has changed, but the concept of the essence of social justice established in the years of socialism has been preserved. This circumstance is crucial for mutual understanding and consent in our society. All subsequent events, including voting on constitutional amendments (2020), serve as convincing evidence in favor of the statement made. These amendments are a specific invention that opens up the possibility for the government to relieve the constantly increasing tension for some time. The fact is that after the departure of tsarism from the historical scene (based on the idea of divine origin of its power), the Constitution represents Russia as a state governed by the rule of law and actually fulfills the function of a social contract. Therefore, according to the established tradition, a change of power always entails constitutional transformations. At the same time, everyone understands that there is a gap between the well-written constitutional norms and the reality of life in the country, which allows the government to administer the affairs at their discretion. Still, the possibilities of maneuvering are far from unlimited. Both the constitutional amendments and the actions of the authorities during the period of self-isolation show a reverse movement towards socialist distribution relations. This is an inevitable payment for the use of market mechanisms in the society, for which, even many years after the start of reforms, distribution relations serve as the main criterion of social justice. By initiating such amendments, the authorities show their concern and desire at least for an ostentatious restoration of social justice, thus increasing trust, harmony, and cohesion in the society.
Trends and factors of the demographic development of Tver oblast in the 20th — early 21st centuries
Authors: Rybakovsky Oleg
Published: March 2021

The article summarizes the reproductive and migration development of one of the most demographically-disadvantaged regions of Russia — Tver oblast, where depopulation has been taking place for more than 50 years. Thus, in 30 years, from January 1989 to January 2019, the population of Tver oblast, as well as its population in working age, decreased by 1.3 times, the number of women of the most active reproductive age (20-39 years) — by 1.5 times. The factors of this negative process are substantiated in the article. First, during the War of 1941-1945 this territory was occupied for three years and became the site of some of the bloodiest battles of this war, including the Battle of Rzhev. Second, from the region in the pre-revolutionary and post-war Soviet times actively went the settlement of the rear and suburban regions, first of all, North European and Asian Russia. Third, the region is on the way between the two main migration recipients («magnets») of Russia — the Moscow and Leningrad macroregions, and its population is steadily decreasing due to outflow to two capitals. The article reveals the extent of demographic, including migration, losses of the region in the later Soviet and post-Soviet times. The circle of the closest migration partners of Tver oblast and the nature of population exchange with them are identified. Changes in the direction and closeness of the region's migration links over the past fifty years have been investigated. The origin of structural waves in the sex-age pyramid of Tver oblast for a century has been substantiated. It is argued to what demographic structural and socio-economic consequences such development of the region has led to. It is concluded about the place and prospects of Tver oblast and its population in modern market economy Russia.

The Internet in the modern world is an integral part of the formation of culture and educational potential of society. The relevance of studying its influence on the individual and social strata of society is determined by its structural and functional capabilities: in fact, it becomes an institution for socialization of new generations, also actively embedded into educational systems. However, in terms of science it is important to understand what influence the Internet has on the formation of basic values, cultural characteristics, attitudes among young people, particularly in the field of financial behavior, which will form the basis of their economic activities and their common future. In this connection, the purpose of this study is an attempt to substantiate the role and influence of social media on the formation of models of financially competent behavior of young people (using the example of Moscow as the leading financial center). The main research methods were content analysis of social media, in particular the social network Instagram (analysis of the content of bloggers positioning themselves as experts in the field of financial management), as well as a mass survey of young people (carried out as part of the initiated by author project of the Laboratory for Study of Behavioral Economics at ISESP FCTAS RAS under the title "Financial culture of the capital's youth") and in-depth structured interviews with experts in the field of financial market and financial behavior. The results of the study make it possible to suggest the existence of a serious influence on the formation of financial culture and financial behavior of young people of the ontent that is popular in social media, as well as the popularity of social networks themselves as a source for the «extraction» of information in the field of economics and finance. This should be taken into account when developing a policy regarding social media activities, in particular bloggers in the field of educational, consulting, commercial and other activities related to increasing financial literacy, culture and formation of various models of financial behavior of young people for the purpose of legal regulation of such activities, because the broadcast content directly shapes not only the way of thinking, but also influences the practical choices and daily activities of young people.

The Slovenian Forest Owners Association (FOAS), which connects local associations of private forest owners at the national level, is facing the problem of professionalizing its activities. Thus, its activities are limited. In order to improve the operation of the FOAS and possible business cooperation with its members within the framework of new business models, we conducted interviews with representatives of FOAS members (n = 24). FOAS members are satisfied with the work of the FOAS, mainly due to its involvement in the legislative process. FOAS members expect that the FOAS will become active in the area of joint timber sales in the future, which is why they showed great interest in business cooperation with the FOAS towards coordinated timber sales. In order to implement this new business model, it is first necessary to promote coordinated sales among forest owners, provide suitable personnel and establish links between timber suppliers and buyers.
SENTIDOS SOBRE CORPO, ESTUPRO E INTERDIÇÃO EM “SOL, LUA E TÁLIA”
Authors: FERNANDES FERNANDA SURUBI
Published: March 2021

Este estudo possui como objetivo analisar o funcionamento discursivo do estupro no conto “Sol, Lua e Tália” de Basile (1634), numa relação entre corpo, memória e interdição. Os sentidos produzidos pela análise colocam em funcionamento uma relação de poder e de sentidos sobre os sujeitos, através de comportamentos que marcam na posição sujeito-mulher uma interdição do desejo. Nessa relação, é no/pelo corpo que esses sentidos se constituem, numa projeção da violência e da interdição, marcados pelos modos de dizer o estupro, sempre de outro modo, como “colheu dela os frutos do amor”, como “posse de meu território”.

The «bronchiolitis» unites a heterogeneous group of diseases of inflammatory nature, the anatomical substrate of which are Airways without cartilage wall-bronchioles. Despite the etiological diversity of bronchiolitis, pathomorphological they manifest a certain set of changes in the lung tissue. This determines the similarity of visualization of different types of bronchiolitis during computed tomography of the chest. The key to successful diagnosis of bronchiolitis is a clear understanding of the definition of this pathology and a comprehensive analysis by a Clinician of anamnestic, clinical, laboratory and radiological data. In this article, we will consider three types of cellular bronchiolitis, which are combined by imaging on computed tomography of the chest pattern «tree in the kidneys»: infectious, aspiration bronchiolitis and diffuse panbronchiolitis.

Published: March 2021

Milk thistle seeds are a unique source of biologically active substances. The oilseed crop studied is used in various fields, both for food purposes, animal husbandry and in medicine. The characteristics of milk thistle oil were considered in the work. Milk thistle seeds are known to contain 35% vegetable oil (seed fat). The oil was obtained with cold pressing. Milk thistle seed oil was chosen as the object of study. Using an experimental extruder, the oil was obtained under the following modes: the annular gap of the grain chamber - 1.25 mm, the screw rotation speed - 190 rpm, the pressing temperature - 353 K. A comparative study of the fatty acid composition of milk thistle oil components with literary sources was carried out. Gas-liquid chromatography on a Chromotek 5000 device was used to determine the composition of the components according to the GOST 31665-2012 method. The calculation for the components of milk thistle oil  on the basis of which the chromatograms were obtained for the amount of fatty acids was made. It was found out that the characteristics of the test sample are comparable with the literature data, but they also have differences, since other fatty acids were found in the oil. 24 fatty acids were identified by gas chromatographic analysis. The following ratio of fatty acids was determined: linoleic - 53%, oleic - 26%, palmitic - 8%, stearic (5%), arachidic (3%) and behenic (2%). The sample under study contains saturated and unsaturated fatty acids. According to the results of the vitamin composition analysis  milk thistle oil contains vitamins A, E and K and minor β-carotene traces which are a valuable source for diet and preventive nutrition.
