Authors: Krylova E. , Garin E. , Tihonov A.
Published: April 2021

Rivers are the basis for the creation of reservoirs, which can radically change the structure and functioning of aquatic and terrestrial ecosystems. Despite the fact that small rivers have long become a model object of research, work on them remains relevant to this day. The purpose of our study was to study the vegetation cover of the mouth section of the small river Chesnava, flowing in the Nekouz and Breitovsky districts of the Yaroslavl region and flowing into the Rybinsk reservoir. The most typical here are open zones with a depth of 0.9–2.5 m, shallow waters 0.1–0.8 m deep with silty, silty-sandy and sandy soils, and strips of periodically flooded coasts with sandy and silty soils that are drained after the water recession. The flora contains 82 species from 30 families and 57 genera. The dominant ecogroup is hygrophytes, cryptophytes and hemicryptophytes predominate in life forms, and boreal and holarctic species in the zonal-regional relation. The vegetation of the river is represented by 19 associations, united in 14 formations, the main ones of which are: Lemna-Hydrochairetum morsus-ranae, Typhetum angustifoliae, Phalarito arundinaceae-Glycerietum maximae, Sparganio emersi-Eleocharietum palustris, Heteroherboso-Eleocharietum palustris, Careto acutae-Phalaroidetum arundinaceae. The expansion of the shallow and gently sloping coastal zone contributes to the active overgrowing of the investigated area.

Background: Development of female genital tract is a complex process and dependent upon a series of events involving cellular differentiation, migration, fusion, and canalization. Mullerian Duct Anomalies (MDA) are uncommon congenital anomalies, but can vary widely and treatable with surgical procedure. Classification system that have been used are classification from American Society for Reproductive Medicine (ASRM) and European Society of Human Reproduction and Embriology (ESHRE) and European Society for Gynaecological Endoscopy (ESGE). Surgical procedure in MDA patient had a high successful rate, but postoperative complication can arise in form of the need for further surgical requirement and acute kidney injury. Case report: A 20 year old girl admitted to obstetric gynecologic clinic with complaints of abdominal pain, amenorrhea, and redness voiding. She experienced abdominal pain since 6 years ago. Previously, patient had history of vaginal drainage procedure when she was 14 years old but she did not felt improvement in complaint and symptom. Cystoscopy and radiology imaging showed vaginal agenesis and renal dekstra agenesis, subsequently patient was planned for a sigmoid vaginoplasty procedure. Identification and exploration during surgery revealed vaginal agenesis, renal dekstra agenesis, hematometra from hemiuterus dekstra, hemiuterus sinistra with asesorius or hipoplasia uterine and hematosalping dekstra. In 5 days post operative, patient suffer anuria and acute kidney injury complication. Acute kidney injury after major surgery involving gastrointestinal was common because of surgical stress response, and agenesis renal condition aggravates this complication.

VOlUME 04 ISSUE 04 APRIL 2021 PAREMIC CLICHES AS A SPIRITUAL LAYER OF MULTICULTURAL COMMUNICATION: CULTIVATING RESPECTIVE VALUES FOR EDUCATORS
Authors:   National University of Life and Environmental Sciences of Ukraine, 15, Heroyiv Oborony St., Kyiv 03041, Ukraine, (Čajka) Oksana Chaika
Published: April 2021

The article considers the linguistic and cultural aspects of paremic clichés as expressions of the spiritual layer of national culture in the context of multicultural communication. The research is based on the main theoretical approaches to understanding the importance of paremiology for the processes of multicultural communication, which makes one of the study objectives, and the material describes such theoretical approaches by underpinning the importance of cultivating multicultural / polycultural values for educators as a fundamental skill for reaching out to and teaching various audiences. The paper reveals a set of language means attributable to nomination of spiritual markers of national culture in paremias, which may as well speak of ethnic identity in the multicultural complexity. Multiculturalism and polyculturalism are distinguished as opposing each other ideologies and/or trends despite the shared concept of intercultural engagement and communication. The paper reveals that paremic clichés as language units, firstly, make part of diversified linguistic corpus in any language and, secondly, are respected as a spiritual layer of multicultural communication in the ideologies of multiculturalism and polyculturalism. Finally, paremic clichés may best serve as intercultural similar and/or distinct indicators for cultivating culturally marked values for global educators, which carry on their roles and responsibilities in the light of mission rather than classroom instruction in multicultural / polycultural settings.

Authors: BARRO Moussa , SANOGO Satafa , ZONGO Mohamed , TRAORÉ Sado
Published: April 2021

Robust Optimization (RO) arises in two stages of optimization, first level for maximizing over the uncertain data and second level for minimizing over the feasible set. It is the most suitable mathematical optimization procedure to solve real-life problem models. In the present work, we characterize robust solutions for both homogeneous and non-homogeneous quadratically constrained quadratic optimization problem where constraint function and cost function are uncertain. Moreover, we discuss about optimistic dual and strong robust duality of the considered uncertain quadratic optimization problem. Finally, we complete this work with an example to illustrate our solution method.

Patients with head and neck squamous cell carcinoma (HNSCC) often develop multiple (pre) malignant lesions. This finding led to the field of the cancerization theory, which hypothesizes that the entire epithelial surface of the upper aerodigestive tract has an increased risk for the development of (pre) malignant lesions, because of multiple genetic abnormalities in the whole tissue region. Demonstration of alterations in histologically normal tumor-adjacent mucosa from HNSCC patients supported this hypothesis. Currently, the question has been raised whether multiple lesions develop independently from each other or from migrated malignant or progenitor cells. Moreover, almost all primary remote tumors from HNSCC patients appear to be clonally unrelated. Therefore, there is more evidence that field cancerization is due to multiple independent events than to migration of genetically altered cells.

В статье рассматриваются пути оптимизации работы Кентауской ТЭЦ за счет изменения водно-химического режима системы подготовки подпиточной воды с целью повышения температуры сетевой воды до 140–145 0С, предлагается метод коррекционной обработки воды с помощью ингибиторов отложений минеральных солей, приведены экспериментальные исследования и результаты влияния ингибиторов отложений минеральных солей и его композиций на кристаллизацию труднорастворимых соединений. Обработка воды ингибитором отложений минеральных солей практически не увеличивает ее минерализации, не усиливает ее коррозионно-агрессивные свойства, не оказывает влияния на биологические обрастания или насосные отложения. Механизм стабилизирующего действия заключается в адсорбции комплексона на микрозародышах кристаллизирующейся соли, что препятствует дальнейшему росту кристаллов и образованию отложений и обеспечивает стабильность пересыщенных растворов. Контроль процесса накипеобразования проводился по показателям общей жесткости и щелочности воды.

В данной статье приводятся результаты опытно-промышленных испытаний использования антрацита взамен кокса, с целью энергосбережения, в условиях текущего производства при выплавке высокоуглеродистого феррохрома на АО ТНК Казхром Аксуский завод ферросплавов (Казахстан). Проблема снижения расхода металлургического кокса без уменьшения устойчивости протекания процессов касается всех переделов, но наиболее важна для стадии производства первичного металла. Минимальный расход кокса рационален как с точки зрения экономии энергии, а также по причине производства высокочистых по примесям металлургических полупродуктов. Применение антрацита листвянского месторождения в условиях текущего производства при выплавке высокоуглеродистого феррохрома на печи типа РКЗ-63 показало себя с положительной стороны. Использование антрацита в навеске шихтовых материалов в количестве 100 кг не ухудшило технологического хода печи. Загружаемый в печь антрацит заменяет кокс практически 1/1. Низкое содержание фосфора в антраците позволяет получать готовый металл с более низким содержанием фосфора. В процессе использования антрацита идет значительная экономия электроэнергии, к тому же антрацит имеет также низкие содержания золы и серы, что благоприятно для технологического процесса и снижения содержания серы в товарном феррохроме.

системы (пакета) Mathcad фирмы MathSoft от аналогов. Использование Mathcad позволяет писать примечания к расчётам вдвое быстрее, но реальная ценность этого приложения – в возможности проверки и отладки любых программ за меньший промежуток времени. Всё это позволяет считать MathCAD одной из лучших расчётных программ для образовательной сферы. Внедрение системы MathCAD в учебный процесс так же актуально, как использование калькулятора в расчётах, редактора формул MathType – для оформления статей и дипломных проектов, AutoCAD – при выполнении графических работ. Основной идеей статьи является внедрение программного блока MathCAD в систему образования Казахстана. Даётся обоснование необходимости внедрения этой программы в учебный процесс. Предлагается в стандарт образования ввести обязательное изучение программы MathCAD на третьем курсе в первом семестре, а во втором семестре студенты должны получать проекты на закрепление знаний по использованию расчётной системы MathCAD. На четвёртом курсе все расчёты в курсовых и дипломных работах должны строго выполняться с применением MathCAD, что позволит ввести контроль правильности выполнения расчётов.

Бұл мақалада каталитикалық риформингті орнатуға арналған катализаторларды сынау және таңдау нәтижелері берілген. Каталитикалық риформинг – республиканың мұнай өңдеу саласының тізбегіндегі іргелі процесс. Мұнайды қайта өңдеудің каталитикалық кезеңінің тиімділігі технологиялық режимдер мен белсенділікті таңдаудың дұрыстығына, қолданылатын катализаторлардың селективтілігі мен тұрақтылығына байланысты. Катализаторлар мұнай өңдеу саласындағы шығын материалы болып табылады. Жұмысты оңтайландыру энергия және экономикалық шығындарды бірнеше есе қысқартуға мүмкіндік береді, өйткені катализаторлар қымбат тұратын компонент болып табылады. Цифрлық технологияны қолдану ірі габаритті қондырғылардың жұмысын талдау және мониторингілеу үшін оңтайлы шешім болып табылады. Зерттеу үшін каталитикалық риформинг процесінің тұрақсыздығы мен көп факторлығын толық ескеруге мүмкіндік беретін математикалық модельдеу әдісі қолданылды. Pt-Re каталитикалық риформинг катализаторларын өнеркәсіптік пайдаланудан нақты деректерді пайдалана отырып, парафиндерді дегидроциклизациялаудың каталитикалық риформингі реакцияларында жоғары селективтілікті көрсеткен ПР-71 катализаторын Қазақстанның жоғары парафинді мұнайын өңдеу үшін жүктеген жөн екендігі дәлелденді. Тиісінше, бұл атмосфераға зиянды шығарындыларды азайту, өңдеу тереңдігі артады, каталитикалық риформинг өнімдері сапалы болады. Сондай-ақ бұл аномалды реологиялық қасиеттері бар қазақстандық шикізатты барынша орынды пайдалануға мүмкіндік береді.

El presente estudio, con enfoque cualitativo de tipo exploratorio-descriptivo, tiene como objetivo identificar y describir los pensamientos, emociones y conductas de 21 adolescentes, de ambos sexos con edades entre 11 y 17 años, quienes habían presentado al menos una conducta de autoagresión. Se aplicaron de forma individual el Instrumento de Riesgo Suicida Adolescente IRSA, la Escala de Intencionalidad Suicida de Beck, y el Cuestionario sociodemográfico. En el análisis descriptivo se calcularon frecuencias, porcentajes, medias, medianas y rangos. Los resultados mostraron que el grupo de participantes tendía a legitimar las diversas autolesiones como parte de su expresión de individualidad, y que el tipo de interacción familiar y las condiciones académicas pueden funcionar como factores de riesgo o de protección.

A água do Canal do Sertão está exposta a reações físico-químicas e contaminações, em função da alta temperatura e incidência solar durante todo o ano. A água é fundamental para a qualidade de vida dos seres humanos. Com isso, é imprescindível que a água usada para abastecimento doméstico apresente características toxicológicas adequadas, livres de microrganismos patogênicos e substâncias nocivas à saúde. Tendo em vista o exposto, o presente trabalho objetivou avaliar a qualidade microbiológica e físico-química da água do canal de Sertão no Estado de Alagoas, através dos parâmetros de qualidade da água que foram analisados nos laboratórios do CESMAC, conforme métodos especificados em Standard Methods for the Examination of Waterand Waste Water, editado pela American Public Health Association APHA et al. (2017). Foram definidos 9 pontos de coleta, abrangendo a área de captação e os 90 km iniciais do canal.De acordo com os resultados, observou-se que alguns parâmetros avaliados não estiveram enquadrados, conforme diretrizes da legislação brasileira, no parâmetro cor, houve uma superação dos limites recomendados para o enquadramento; valores de sódio encontrados restringem o uso de água para o consumo humano e valores de magnésio obtidos na pesquisa estiveram abaixo do permitido para consumo humano e irrigação. Os demais parâmetros avaliados não apresentaram restrição de uso nem para irrigação nem para consumo humano. É necessário a avaliação da qualidade microbiológica ou sanitária da água do canal do sertão, antes de recomendá-la, para consumo humano ou irrigação.
YEDI KULE - MONUMENT ROAD RACE: THE CONSTRUCTION OF THE 3D MAPPING ANIMATION OF THE OLD CITY OF THESSALONIKI, GREECE

Published: April 2021

This project refers to the construction of a 3D map of Thessaloniki’s historical route. The Yedi Kule Conquest – Monument Road Race took place in the old city of Thessaloniki, which was built during the Byzantine and Ottoman period.  The purpose of this project is the digital recording of the castles, the monuments, the old churches, the traditional buildings, and the squares which are prime examples of the architectural beauty of the place. The methodology of the project is based on the online software Google Earth Studio and Adobe Premiere Pro. These are the tools of digitization, rendering, and building process of the animation. With this methodology, the authors achieved the documentation of land use and the architectural landscape. The animation is a credible graphic index of the historical background of Thessaloniki. The Yedi Kule area constitutes of a cultural mosaic made from different historic periods. The buildings and the neighbourhoods give the sense of transition of the narrow roads, the old Christian churches, the house of the first Turkish governor, and the byzantine castle to the modern city. In Thessaloniki, three historic periods coexist the Ancient Greek/Roman, the Byzantine, and Ottoman Empire. The responsibility of the governmental politics and of every citizen of Thessaloniki is to promote and preserve the historic background of the city. The final product offers a good opportunity for the digital storage of Thessaloniki’s old city. The animation creates an interactive environment that portrays the current image of the transition from the old to a modern city.
DIGITAL CULTURE, UMWELT AND ALETHEIA AN ONTOLOGICAL INTRODUCTION
Authors: Pasqui Andrea
Published: April 2021

The paper presented here focuses on the idea of interpreting the digital culture as an image of the material culture rather than a mere copy of it. First of all, we should ask ourselves what an image really is; it is in investigating its deep meaning, which is often devalued due to the enormous dissemination of void images, that we can overcome the superficial concept of the digital as a digitalised copy. The description of an archaeological artifact cannot prescind from its physical and material appearance, but has to go further towards its profound nature and meaning. Considering the so-called aura of archaeological and artistic objects as an engagement between the hic et nunc of the object and the hic et nunc of the observer it will be possible to go beyond in the comprehension of the agency of the objects. Moreover, it is necessary to consider technology as a way through which objects could reveal themselves in a process of ἀλήθεια and not just a tool with the only scope of showing itself and its capacities. Considering digital copies as images could yield compelling challenges: every archaeological object, at any scale from the very little to the very big, has its own lost Umwelt: a way of being entangled in the world in which it was created. Probably, no answer will be provided within this paper, but suggestions to move towards an ontology of digital objects and their relationship with virtual realm.
CRITERIA AND TOOLS TO CATALOGUE BRICK-MASONRY VAULTS. THE GIS-DATABASE OF FRAME, A FASCE AND PLANTERIAN VAULTS BETWEEN THE 16TH AND 18TH CENTURY IN NORTHERN ITALY
Authors: Stanga Chiara
Published: April 2021

The paper describes a proposal for criteria and tools to catalogue brick-masonry vaulted systems in Northern Italy between the 16th and 18thcenturies. Along with the standard geometric typologies, three novel parameters (maîtresses voûtes, voûte sur le plan d'une autre voûte, constructive features) are proposed to include the constructive features in the vault taxonomy. The novel parameters help catalogue three vaulting types that can be considered the metamorphosis of cloister vaults: frame, a fasce, and planterian vaults. The database was realized in MS Access and then imported into QGIS 3.10. Database and GIS have been operative tools to form hypotheses on vault disseminations, highlighting the recurrences and specificities across time and space of some peculiar construction techniques. The database collects the acquired information on each vault (building type, geolocation, building date, vaulting type, vault dimensions and description and, whenever possible, photogrammetric survey, 3D modelling, and thermographic survey). In the future, the database should be published online, making the data available and building a broader dataset to share the information.
VIRTUAL TERRESTRIAL LASER SCANNER SIMULATOR IN DIGITAL TWIN ENVIRONMENT

Published: April 2021

We are presenting a Terrestrial Laser Scanner simulator - a software device which could be a valuable educational tool for geomatics and engineering students. The main goal of the VirScan3D project is to cover engineering digitisation and will be solved through the development of a virtual system that allows users to create realistic data in the absence of a real measuring device in a modelled real life environment (digital twin). The prototype implementation of the virtual laser scanner is realised within a game engine, which allows for fast and easy 3D visualisation and navigation. Real life objects can be digitised, modelled and integrated into the simulator, thus creating a digital copy of a real world environment. Within this environment, the user can freely navigate and define suitable scanning positions/stations. At each scanning station a simulated scan is performed which is adapted to the technical specifications of a real scanner. The mathematical solution is based on 3D line intersection with the virtual 3D surface including noise and colour as well as an intensity simulation. As a result, 3D point clouds for each station are generated, which will be further processed for registration and modelling using standard software packages.
