Biodegradação do herbicida atrazina por Saccharomyces cerevisiae
Authors: Toller Nathalia , Guimarães Elisete , Bravo Claudia
Published: October 2021

RESUMO Tendo em vista os vários problemas ambientais e de saúde que o uso crescente de agrotóxicos vem causando, é necessário a otimização de técnicas que visem a sua rápida degradação. A atrazina é um herbicida utilizado no controle de ervas daninhas, principalmente nas culturas de milho e cana-de-açúcar. Nesse sentido, o objetivo deste estudo foi verificar a eficiência da levedura Saccharomyces cerevisiae na degradação do herbicida atrazina em solo contaminado com diferentes concentrações do produto comercial. Foi igualmente testado o efeito da adição de palha de milho no experimento. A fim de determinar a quantidade de gás carbônico (CO2) liberado durante os ensaios, o qual reflete a atividade da microbiota do solo responsável pela degradação de compostos orgânicos, foi utilizada a técnica da respiração basal do solo. E, paralelamente a isso, para verificar a concentração de atrazina ao longo do experimento (tempo inicial, aos 7, 14 e 63 dias), foi utilizada a análise de cromatografia gasosa acoplada ao espectrômetro de massas (CG-MS). Por meio da análise estatística dos dados de respiração basal do solo, o fator de bioaumento com a levedura foi o mais significativo, seguido da adição de palha de milho. Verificou-se o declínio da concentração de atrazina por intermédio das análises cromatográficas. Assim, sugere-se que a biorremediação com S. cerevisiae tem potencial para elevar as taxas de degradação do herbicida no solo.

RESUMO O cimento supersulfatado (CSS) se destaca por utilizar uma pequena ou quase nenhuma quantidade de clínquer (responsável pela alta liberação de CO2 na atmosfera na produção de cimento Portland - CP), e também, por apresentar boa resistência em ambientes com altas concentrações de sulfato. Neste trabalho foi verificada a variação dimensional das amostras de CSS (constituída por escória, gipsita ou fosfogesso como fonte de sulfato de cálcio), expostas à solução de sulfato de sódio, como proposto na NBR 13583 (ABNT/2014), comparando os resultados obtidos com os do CP. O ensaio de variação dimensional mostrou que a amostra de CP foi a que apresentou a maior expansão. Dentre as amostras de CSS, observou-se que a maior expansão foi observada naquela constituída por fosfogesso como fonte de sulfato de cálcio. As análises de microestrutura (DRX, DSC e MEV) identificaram etringita e gipsita como fases expansivas nas amostras de CP, que justifica a sua maior expansão dentre todas. No entanto, a maior expansão do CSS à base de fosfogesso foi atribuída ao maior tempo de formação da etringita e não à quantidade formada, mas que necessitaria de mais investigação para confirmar a hipótese.

Published: October 2021

ABSTRACT Ahead of the incorporation of residues in concrete composition, there is a decline in the environmental impact of buildings. One of the goals of today’s development is the employment of low-impact energy sources, such as thermoelectric. Thermoelectric industries display a high rate of residues, among which is pointed out coal bottom ash (CBA) (15% total residues), which have density superior to fly ash and accumulates in silos. Considering this scenario, this paper assessed the incorporation feasibility of CBA in the composition of cellular concrete, replacing silica fume. This study comprehended CBA characterization and application. For such, it was performed a scanning electron microscope (SEM) associated with Energy dispersive spectroscopy (EDS) analysis, laser granulometry, X-ray diffraction (XRD), X-ray efflorescence and density. Following the incorporation of the residues in cellular concrete in place of silica fume, it was performed compression strength analysis and SEM anew, evaluating the impact of CBA’s insertion in concrete’s microstructure. The XRD results are complementary to the other analyses. With SEM technique, it was observed the predominance of spherical-shape particles. The compressive strength of CBA concretes was superior to the reference concrete from 0,13 to 0,74MPa.

RESUMO Neste trabalho obteve-se corpos de prova provenientes de painéis aglomerados confeccionados a partir de resíduos de madeira serrada de eucalipto. Caracterizou-se o módulo de elasticidade a partir da frequência flexional e longitudinal e módulo de cisalhamento por meio de ensaios não destrutivo e destrutivo. Foram avaliadas a resistência biológica dos painéis a partir da reação aos fungos Neolentinus lepideus e Brunneoporus malicola (≈ Gloeopyllum trabeum) e com térmitas Cryptotermes brevis e Nasutitermes sp. Nestes ensaios determinou-se a perda de massa após o período de ataque. Observou-se relação entre o método de vibração flexional do corpo de prova retangular com o módulo de elasticidade estático, possibilitando o uso desse método. Os painéis com menor teor de tanino (2%) no adesivo apresentaram desempenhos mecânicos inferiores. As técnicas utilizadas mostraram ser possível a estimação das propriedades em painéis aglomerados. Os painéis apresentaram-se mais resistentes para o fungo B. malicola com as menores perdas de massa (média geral de 15,73%) em relação ao N. lepideus (45,73%). Os painéis confeccionados com 100 % de tanino-formaldeído promoveram maior perda de massa quando em contato com a térmita Cryptotermes brevis (12,54%) e para ambos os fungos B. malicola (21,2%) e N. lepideus (53,8%). Para as térmitas Nasutitermes sp. os painéis com 100% de tanino foram menos degradados.
Characterising the effect of particle size disparity on liquefaction resistance of non-plastic silty sands from a critical state perspective
Authors: Wei Xiao , Yang Jun
Published: October 2021

Widespread liquefaction has been frequently observed in silty sand deposits during recent large earthquakes. How to properly evaluate the liquefaction potential of silty sands has emerged as a matter of great concern. This paper presents an investigation into the problem through a comprehensive experimental programme in conjunction with a newly developed framework of analysis. Focus is placed on the effect of particle size disparity and its interplay with the effect of fines content – two fundamental issues for which current understanding is limited. A novel finding of the study is that the liquefaction resistance of sand–fines mixtures, defined as the cyclic resistance ratio (CRR) leading to failure at a specific number of loading cycles, is almost uniquely related to the state parameter (ψ) defined in the critical state theory, regardless of particle size disparity and fines content. To quantify the combined effects of fines content and particle size disparity, an empirical model is put forward along with a practical method for estimating the critical state parameters of silty sands. The model is evaluated using experimental data on a range of sand–fines mixtures in the literature, showing a reasonably good performance and attractive advantages. A grain-scale mechanism is also suggested to explain the observed effects.

Din Yolu dergisinin, daha önce Türkçe tercümesi yapılmamış, ilk dönem İslam tarihini anlatan Corcî Zeydân’ın “Nil Bakiresi Armanosa” isimli romanını çevirerek tefrika etmesi ilgi çekicidir. Bu çalışmada Din Yolu’nun tüm sayıları incelenerek, derginin edebi özellikleri, Kur’an-ı Kerim’in Türkçeye çevrilmesi ve ortaokullarda din eğitimi gibi dönemin öne çıkan tartışmalarına yaklaşımı; Diyanet ve İlahiyat Fakültesi gibi kurumlar hakkındaki düşünceleri tespit edilmek istenmiştir.
Development of automatic system for Unmanned Aerial Vehicle (UAV) motion control for mine conditions
Authors: Kim M. L. , Pevzner L. D. , Temkin I. O.
Published: October 2021

Underground mining operations are connected with significant risks of technogenic accidents, which can be catastrophic. Mitigating the consequences of such phenomena directly depends on the reliability and efficiency of information about the state of parameters of many technological processes, mine workings and facilities located in them. At failure of standard systems of industrial telemetry in conditions of underground mining the creation of new information channels and places of information measurementbecomes practically impossible in case of emergency situation development. This predetermines necessity of use of essentially new systems of gathering and transfer of the information, based on robotized autonomous complexes. The task of acquiring reliable information about the situation in an emergency mine working with the help of drones (unmanned aerial vehicles or UAV) in order to make rational decisions in the course of the rescue operation is quite relevant. The aim of the paper was to develop a system of automatic control of an unmanned aerial vehicle (UAV) movement in confined space of a mine working, with significant perturbations of the mine air flow. The mathematical model of UAV movement in mine conditions, based on Euler angles or quaternions, was substantiated. The method of positioning through triangulation with the use of radio beacons was accepted as the basic method that allowed to determine the current position of an UAV. It was proposed to solve the problem of creation of the automatic system for an unmanned aerial vehicle movement control with the use of a hierarchical multiloop control system. The route planning algorithm was formed on the basis of the Dijkstra algorithm. For this purpose, discretization of the future motion space was performed, a labeled connected graph was constructed, on which the arc weights were the distances between the route points. A simulation experiment was implemented. The average deviation from the planned trajectory when flying at a speed of 10 m/s with payload mass up to 0.6 kg did not exceed 1 m, and the maximum deviation was unacceptably large. When flying at 6 m/s with payload mass up to 0.6 kg the average deviation did not exceed 0.3 m, and the maximum deviation, 1.2 m. The results of simulation of movement along the route towards the disturbing mine airflow showed that the control system allowed the UAV with payload of 0.6 kg to withstand the oncoming flow up to 8 m/s. It was obtained that with payload mass of 0.6 kg, the braking distance does not exceed 6 m if the UAV had a speed of 6 m/s, and the braking distance does not exceed 12 m at the speed of 10 m/s. The performed simulation studies confirmed the operating capability of the developed system for automatic motion control.

Published: October 2021

From the point of view of systems and field theory, the value attached to a work of art, for example a literary text, is not only the result of the intrinsic characteristics of the text but also includes connections with institutions such as publishers, and factors like literary prizes, the value judgments of literary historians, of reviewers, and of literary critics. The current study examines the mentions of canonized Afrikaans writers in nine academic journals over the past two decades, taking into account more than 5 000 publications and more than 70 000 pages. It is shown which authors are mentioned most, but also which authors are mentioned most often together, and it is shown that authors are mostly mentioned together in the terms of genre. Although the current study represents a large study of the visibility of authors in the study of Afrikaans literature, suggestions for further research are also made.

Российской рынок кредитных рейтингов представлен как международными, так и национальными рейтинговыми агентствами, среди которых стандарты присвоения рейтингов имеют свои методологические особенности. Несмотря на то, что проведено немало количественных исследований, измеряющих различия мнений рейтинговых агентств относительно кредитоспособности одного и того же эмитента, большинство из них направлено на анализ причин этих различий, а не на качественное сопоставление присвоенных рейтинговых шкал и их оценок. Целью исследования было рассмотреть и сопоставить между собой рейтинговые шкалы как российских, так и зарубежных рейтинговых агентств для различных экономических объектов. В статье представлены результаты эмпирического исследования, в ходе которого были сопоставлены различные рейтинговые шкалы применительно к российским промышленным компаниям и финансовым институтам (банкам и страховым компаниям). Ввиду отсутствия общепринятой методики рейтингования оценка кредитоспособности эмитентов и различных экономических объектов усложняется. На основе метода мэппинга было показано как рейтинги российских и международных агентств сопоставлены между собой и их различные градации. В работе представлены результаты регрессионного анализа, на основе использованной финансовой статистики микро- и макроуровня были получены сравнительные оценки кредитных рейтингов финансовых институтов, в том числе для различных стран, учтены также качественные различия и причины расхождений между данными рейтингами. В результате тщательного сопоставления рейтинговых шкал была построена и приведена в статье таблица соответствия кредитных рейтингов для рейтинговых агентств, аккредитованных в России.

Perceived Stress and Coping Strategies of Healthcare Workers in the Context of the COVID-19 Pandemic
Authors: Doronina T.V. , Okulova A.E. , Arcishevskaya E.V.
Published: October 2021

In 2020, the world faced the COVID-19 pandemic. Medical workers who are fighting for the lives and health of patients in the "red zones" were on the front line in this struggle. The huge level of responsibility, the increasing duration of shifts, difficult working conditions, fears for their health and the health of their loved ones, and many other factors determined the fact that doctors themselves began to need support for their physical and psychological well-being. The purpose of our work was to study the level of perceived stress in the context of the features of coping strategies in medical professionals with different practical experience (students, practicing doctors) in the conditions of the COVID-19 pandemic. The total number of study participants was 59 people, including 35 experienced medical workers aged 33 to 72 years (M=47,88; SD=9,44) and 24 medical students aged 20 to 29 years (M=24,16; SD=3,21) without professional experience, but who voluntarily went to work in the "red zones" during the pandemic. As a result of the study, data were obtained on high levels of perceived stress and overstrain by medical professionals during the COVID-19 pandemic, which is especially pronounced in students. The differences between experienced doctors and medical students were revealed according to the criterion of their preference for certain coping strategies, namely, the predominance of "Escape–avoidance" coping among students. The connection of dominant coping behavior strategies with the level of perceived stress is also established: students who resort to confrontational coping experience a higher level of perceived stress, and a decrease in their level of overexertion is associated with a greater degree of self-control strategy. Experienced doctors do not have both of these connections.
Narrative Self-Representations of Socially Oriented Expectations of Persons with Intellectual Disabilities
Authors: Kuzmina T.I.
Published: October 2021

The article examines the theoretical and methodological foundations and empirical implementation of the approach to the study of narrative self-representations in the field of socially oriented expectations of young and adult persons with intellectual disabilities. Socially oriented expectations largely determine the behavioral representations of the subject in relation to the outside world and other people. There are no special methods for studying the socially oriented expectations of adults with intellectual disabilities, in connection with which an approach can be proposed using the content analysis of narrative representations obtained in the framework of the study of socially oriented personality self-structures (social self). In this case, the coding is based on two parameters: the frequency of occurrence of representative references and the emotional orientation of representative references to socially oriented expectations. With the use of latent coding, based on the semantic analysis of speech units and representative references, it becomes possible to distinguish semantic clusters describing areas of life for which respondents have socially oriented expectations of a particular emotional orientation. This approach makes it possible to overcome the difficulties of analyzing the verbal production of persons with intellectual disabilities, arising in connection with the presence of systemic speech underdevelopment in the latter. The high values of the coefficient of agreement of expert opinions obtained in this study indicate the relevance of the proposed method for obtaining reliable data. The quantitative ratio of the narrative representations of socially oriented expectations between adolescence and adulthood changes insignificantly, there is a qualitative redistribution of the inter-thematic semantic load, as well as a change in the emotional component of the narrative representations of socially oriented expectations of persons with mild intellectual disabilities.
Lex genetica — multilayered pie on the current legal map of the world
Authors: Zakharova M. V.
Published: October 2021

This research paper deals with the issues related to Lex genetica on the current legal map of the world at the general theoretical level of scientific knowledge.

Special focus is on the aspects of qualitative assessment of Lex genetica issues (I), as well as the compositional components thereof (II).

The author comes to the conclusion that: Five basic levels of Lex genetica as a socio-normative system should be considered:

— bioethical;

— associated with the prevalent method of law formation for a certain legal system and (or) legal community;

— judicial;

— international;

— the level of “legal Esperanto”.

The overall design of Lex genetica should be coordinated with national models and standards. For Russia — that, in many respects, is just beginning to embark on the path of building a national policy in the sphere of Lex genetica — a legal structure which can be metaphorically called a “sun” (with regulation based on documents serving as guidelines) might become such a model. In France, for example, such documents serving as guidelines include the Bioethics Law.

Published: October 2021

This article is devoted to the study of main directions in which the relations in the field of the human genome already exist (and have partial legal support) and require their own legal regulation. These directions stand in the form of several paradigms of legal regulation of the relations arising from the use of genomic technologies; these are consumer (social), medical and forensic (forensic) paradigms. In addition, the presented article sets the task to assess the current Russian legislation for its compliance with modern achievements in the field of the human genome and the prospects for its improvement based on the best foreign and international experience.
Models of federalism in Switzerland and Germany: a comparative analysis
Authors: Gulyakov A. D.
Published: October 2021

The article is the first to structure the concept of “model of federalism”. According to the author, it includes such essential elements as the initial factors that influenced the formation of the state, the stages of its development and the essential components of the model, namely, historical-typological and genesis ones features of federalism and the vector of development. Based on the use of historical and state literature, constitutional and legal materials, and the results of a recently published international political science project, the author examines the models of federalism of neighboring countries-Switzerland and Germany, formed in the middle of the XIX century, proposes its graphic description. These states vary in territorial extent and state dynamics, but are still similar at the initial stages of the formation of a federal model, namely the transition to a federal form from a confederal one. Also, the Swiss and German models were radically different from the point of view of their essence and their genesis, but they had a uniform centripetal vector, which in modern globalization conditions is characterized by a strengthening of the management center and a decrease in the autonomy of the subjects.

It's pointed out that this democratic form was initiated in 1989 in а Brazilian city Porto Alegre and then it was spread not only over Latin America but also over other continents. Special attention is paid to the countries of Europe where participative budgeting was implemented most actively. Positive features of participative budgeting as well as its possible disadvantages are analyzed.

The author argues that participative budgeting being one of the forms of participative democracy remains at the same time closely tied to the institutions of representative democracy. The initiator of its implementation remains most often municipal executive power as a whole or its individual representatives and first of all heads of local administration.

Natural language processing is one of the branches of computational linguistics. It is a branch of computer science that includes algorithmic processing of speech and natural language scripts. The algorithms facilitate the development of human-to-machine translation and automatic speech recognition systems (ASRS). ASRS use is twofold: accurately converting operators speech into a coherent and meaningful text and using natural language for interaction with a computer. Currently, these systems are widely used in medical practice, including anatomic pathology. Successful ASRS implementation pivots on creation of standardized templated descriptions for organic inclusion in the diagnosis dictation, likewise on physician training for using such systems in practice. In the past decade, there have been several attempts to standardize surgical pathology reports and create templates undertaken by physicians worldwide. After studying domestic and foreign literature, we created a list of the essential elements that must be included in the template for macro-and microscopic descriptions comprising the final diagnosis. These templates will help in decision-making and accurate diagnosis as they contain all the imperative elements in order of importance. This approach will significantly reduce the need for re-examination of both fixed macroscopic material and the preparation of additional histological sections. The templates built into ASRS reduce the time spent on documentation and significantly reduce the workload for pathologists. For the successful use of ASRS, we have developed an educational course, Digital Speech Recognition in an Anatomical Pathology Practice, for postgraduate education of both domestic and foreign doctors. A brief description of the course is presented in this article, and the course itself is available on the Internet.

Objective: To investigate the effect of advanced nursing on the quality of life and the prevention of complications in patients with breast cancer undergoing PICC (Peripherally Inserted Central Catheter) chemotherapy. Methods: From January 2017 to January 2020, 98 patients with breast
cancer undergoing PICC chemotherapy in our hospital were divided into control group and study group by random sampling. The patients were given routine nursing and advanced nursing intervention on the basis of routine nursing. The psychological status, complications and quality of life of
the patients were compared. Results: There was no significant difference in HAMA, HAMD score and QLQ-30 score before nursing (P > 0.05). The scores of HAMA and HAMD in the study group after nursing were lower than those in the control group (P < 0.05), the scores of QLQ-30 were higher
than those in the control group (P < 0.05), and the complication rate was lower than that in the control group (P < 0.05). Conclusion: The intervention of advanced nursing mode in patients with breast cancer treated with PICC chemotherapy can effectively alleviate the influence of negative
emotion on chemotherapy, reduce the occurrence of complications and improve the quality of life. This mode has high clinical value.
Tobacco Control Policy Based on Environmental Protection Law

Published: October 2021

Objectives: Based on the environmental protection law, this paper analyzes our current tobacco control policy and studies the effectiveness of the follow-up policy. Methods: This paper studies the impact of environmental law on tobacco industry and tobacco control from the legislative
principles and regulatory subjects of environmental protection law. Grasping the basic connotation of tobacco control policy is the premise of understanding and implementing tobacco control. This paper analyzes tobacco control policy from the perspective of policy network and policy tools.
Through the description of Smith policy model, find out the deficiencies in the implementation of tobacco control policy. Results: The smoking population in China tends to be younger, and the control of teenagers' smoking behavior should be more strict. Conduct investigation and management
around the school, put forward certain requirements for students' parents, and carry out health education for students. Based on the legislative intention of environmental protection law, we should use policy tools, policy network and policy implementation process theory to supervise and manage
the whole process of tobacco control implementation in China from the aspects of tobacco system, policy formulation, policy implementation and policy evaluation.. Conclusion: The government should strengthen the scientificity of tobacco control policy-making and improve its operability and
unity. It should improve the implementation system of tobacco control policies and improve the construction of law enforcement subjects. An effective administrative punishment mechanism should be established and the information disclosure system of tobacco control policy should be strengthened.
The social members should be guided to participate in and supervise. We should evaluate tobacco control policies and strive to improve the formulation, implementation and evaluation of tobacco control policies.

To investigate the efficacy of bundle management in reducing EN complications in ICU enteral nutrition (EN) patients. Methods: In this study, 90 patients with enteral nutrition who were admitted to our hospital and ICU from January 2018 to January 2021 were randomly divided into two
groups by random number method: control group (n = 45) treated with routine nursing management and study group (n = 45) treated with bundle management by random number method. The nursing outcomes of the two groups were compared. Results: The incidence rate of enteral nutrition complications
in the study group was significantly lower than that in the control group (P<0.05). The nutritional indexes after intervention in the study group were significantly better than those in the control group (P<0.05). There was no significant difference in the relative ratio of nutritional
indexes before intervention between the two groups (P>0.05). The satisfaction degree of the patients' family members in the study group was significantly better than that of the patients' family members in the control group (P<0.05). Conclusion: Bundle management measures for patients
with enteral nutrition in ICU can effectively improve the nutritional index of patients and the satisfaction of their family members, and reduce the incidence of complications of enteral nutrition, which has obvious clinical value.

A cell is an organic whole containing biological macromolecules such as nucleic acid and protein. Human cells contain about 15,000 proteins, which play an important role in the development of cell life. This article aims to study the effect of phytoestrogens on the proliferation of
breast cancer cells MCF - 7. The estrogen - dependent MCF - 7 cells described in this article are grown on average DMEM (containing calf serum 10) and connected to single cell culture. Five days before adding the test product, the cells were washed with PBS and converted into red - free phenol.
High - sugar DMEM containing 5 parts of bovine embryo serum was cultured and treated with activated charcoal glucan glycosides. In the experiment, four dose groups of solvent control, estrogen control, anti - estrogens and two test substances were used for control, and the proliferation of
MCF - 7 cells was analyzed by integration method and flow cytometry. The experimental results in this article show that compared with the solvent control group, GS can significantly inhibit MCF - 7 cell proliferation and cell DNA synthesis, and G/M can block the cell cycle and produce a similar
inhibitory effect. 96mol/L zein treatment for 24 hours can significantly promote MCF - 7 cell proliferation and cell DNA composition, promote cell cycle, and increase cell separation and proliferation index.

Abstract. Inconsistency of modern conditions of commercial banks operation pose a threat to their activities and existence. Therefore, the problem of ensuring the financial security of banks is relevant. Ensuring the financial security of the bank should be based on a scientifically sound strategy that involves action on certain functional components of security.
It is proposed to use a functional approach to the integrated assessment of the level of financial security of a banking institution, which takes into account four groups of indicators - capital and resource, credit and investment, currency security, as well as the security of bank income and expenses. This approach makes it possible to quantify the impact of each group of indicators on the level of financial security of a banking institution. An integrated assessment of the key components of the bank’s integrated financial security indicator revealed that the four surveyed banks are characterized by a sufficient level of financial security. The results of the integrated indicator of financial security of the bank should be used in developing a strategy for ensuring the financial security of the bank.
The article proposes and substantiates the theoretical and methodological foundations of the strategy for ensuring the financial security of the bank. It is substantiated that to achieve a certain level of financial security of the bank it is advisable to use the GAP-method. It is proved that the application of this method will allow to single out only those components that have the greatest impact on the level of bank security and which need to be influenced. It is established that the strategy of ensuring the financial security of a banking institution should be aimed at bridging the gaps in key indicators. The methodology of game theory was used to establish the expediency of overcoming strategic gaps. It is proved that the application of the chosen methods of strategic planning will allow to quickly identify the causes of deviations from the safe level of the bank and justify the feasibility of influencing certain factors.
 Keywords: financial security of the bank, financial security strategy, GAP-method, integrated indicator of financial security of the bank.
