Authors: Nahornyi Y. V , Ivanov I. Y.
Published: August 2021

Purpose. The research is aimed at the development of scientific and technological bases for determining the utility of passenger transport services for the population in the conditions of formation of phased quality management. Methodology. The structure of the utility of passenger transport services for the population is determined on the basis of developing a systematic representation of the characteristic impact of the perception of management decisions effectiveness for improving the quality of transport services on mobility. The account of complex system properties of city public passenger transport is realized by construction of interlevel interrelations and establishment of methodical regulations for coordinating the parameters of quality management of public transport service with the indicators of its utility perception. Findings. The presented logical sequence of population mobility formation is based on reproduction of the general conditions of increasing transport service utility due to step-by-step realization of control actions that makes it possible to establish conditions of their expediency and parameterization. A model of marginal utility has been developed to qualitatively assess the technological utility of urban public passenger transport. It is presented in the form of a category that reproduces the relationship between the result of changes in the quality of transport services, consumer utility of transport services and the level of resources used. Originality. The procedure for assessing the consumer utility of urban public passenger transport has been formalized, which, in contrast to the existing ones, is based on the established impact of technological parameters of routes on the formation of population mobility and ensures accounting of transport service quality indicators in determining the technological utility. Practical value. The application of the theory of utility in improving the operation of urban public passenger transport in general contributes to the development of the theory of passenger traffic management and can significantly increase the effectiveness of the choice of rational management measures to improve technological processes and the quality of transport services. The conditions for the formation of a positive impact of consumer utility of urban passenger transport on the mobility of the urban population are established. Based on the selected connection, it is possible to form a system of parameters for assessing the quality of public transport services.

Authors: Barbosa Cristina , Cruz Adrielle Spinelli da , Barreto Maria Lúcia
Published: August 2021

ABSTRACT: Spontaneous polydactyly has been described in several species, but only one report about it in Swiss mice. The aim of the current study was to report the spontaneous occurrence of pre-axial polydactyly in Swiss mice. Clinical examination showed one extra toe laterally to the first digit, in the plantar region, alopecia in the back, altered face growth anatomy and changed perineal region anatomy. Pre-axial polydactyly in the tibial side, fused metatarsals and Y-shaped free phalanges were evidenced in the radiographic images. Pre-axial polydactyly observed in the plantar region differed from that in reports on albino Swiss mice with post-axial polydactyly (Po/Po+) phenotype featured by one extra toe in the ulnar side of one, or both, front limbs, which is the dominant feature. The observed findings highlight the importance of both clinical examinations and close attention by professionals involved in rodents’ breeding on physical changes resulting from different causes, including the genetic ones, since they reveal mutations and, sometimes, new biomodels.

Authors: Gonçalves Michelle Carreirão , Costa Amanda Torres Vieira da
Published: August 2021

Resumo: O objetivo deste trabalho foi entender como mulheres praticantes de fisiculturismo conformam suas subjetividades atléticas por meio da modificação corporal extrema. Realizamos entrevistas semiestruturadas, de maneira remota via plataforma Jitsi Meet, com três atletas selecionadas conforme seu tempo de prática e experiência em distintas categorias do fisiculturismo. Nossa análise foi conduzida pelas técnicas que atuam no desenvolvimento de uma identidade esportiva das fisiculturistas pesquisadas, a saber: treinamento, alimentação e química. Os dados mostram que o corpo dessas mulheres pode ser pensado em analogia a um laboratório, ‘lugar’ de experimentos extremos e testagens constantes que geram um tipo de desempenho atlético, bem como um tipo de subjetividade atlética.

Authors: Brito Leandro Teofilo de
Published: August 2021

Resumo: Este ensaio discute as disputas sociais de sentidos sobre a masculinidade no esporte brasileiro, problematizando questões contemporâneas que tensionaram os significados do masculino nesse contexto. Para subsidiar a discussão, é realizada uma crítica pós-fundacional à noção de masculinidade hegemônica de Raewyn Connell, com base nos estudos de Ernesto Laclau e Chantal Mouffe, e recorrendo às perspectivas pós-estruturalistas por Jacques Derrida e Judith Butler, além de incorporar a crítica decolonial às teorias do Norte Global, propondo o construto teórico masculinidade queer/cuir/kuir para interpretação de significações do masculino no contexto contemporâneo do esporte brasileiro.
“Sou negro, homossexual e tenho doença mental”: intersecções em jornais portugueses
Authors: Gonçalves Vivianne Oliveira , Pereira Henrique
Published: August 2021

Resumo: O objetivo do estudo foi investigar os discursos sobre homossexualidade e raça no meio esportivo, produzidos a partir da ‘saída do armário’ de um atleta português, e veiculados em jornais on-line, no período de 2018 a 2019. Utilizou-se, como aporte teórico para a análise dos dados, a Análise do Discurso francesa. Os resultados indicaram que a construção de padrões que legitimam o esporte profissional afasta, silencia e exclui os indivíduos que não se adequam à ‘norma’. Nos comentários dos leitores, a revelação do atleta foi vista com incredulidade, desconfiança e negação, que não deveria ser divulgada ao espaço público. Nos depoimentos do atleta, o coming out foi compreendido como um processo de revelação que tem como consequência a expressão da liberdade e a autoaceitação, sendo a constatação da doença mental o maior desafio.
Expressões e corporalidades de mulheres cis e homens trans no ambiente futebolístico
Authors: Pisani Mariane da Silva , Pinto Maurício Rodrigues
Published: August 2021

Resumo: Neste artigo trazemos as reflexões etnográficas de dois campos de pesquisa distintos. O objetivo é evidenciar como as estruturas machistas e LGBTfóbicas são vivenciadas por mulheres e também por homens trans durante a prática esportiva futebolística. Sabe-se que os esportes, sobretudo o futebol, são considerados campos privilegiados na produção e reiteração de expressões normativas de masculinidade, visto que tomam o homem cisgênero e heterossexual como o seu natural praticante e interlocutor. Em razão disso, o machismo e a LGBTfobia são estruturantes do campo futebolístico, uma vez que mulheres e pessoas LGBTQI+ são ainda constantemente interpeladas e veem a sua presença nesse campo ser recorrentemente questionada e até mesmo depreciada.

Published: August 2021

Resumo O objetivo desta pesquisa foi compreender as perspectivas de docentes e estudantes brasileiros sobre o papel da terapia ocupacional na Atenção Primária à Saúde (APS). Trata-se de estudo de caráter exploratório e com metodologia qualitativa realizado por meio de entrevistas semi-estruturadas com 17 docentes e de nove rodas de conversa com a participação de 67 estudantes. A análise temática revelou duas categorias: 1- Contribuições da terapia ocupacional para a Atenção Primária à Saúde; e 2- O papel específico da terapia ocupacional na Atenção Primária à Saúde, que se traduzem em oferta de cuidado integral, compreensão ampliada do contexto territorial, do cotidiano e ações dirigidas à promoção da participação nas atividades em diversas áreas da vida das pessoas atendidas. No entanto, a terapia ocupacional na Atenção Primária à Saúde necessita ser ainda mais explorada para que seja possível sistematizar e aprofundar o desenvolvimento de suas práticas na APS.
OS PROFESSORES DEPOIS DA PANDEMIA
Authors: Nóvoa António , Alvim Yara Cristina
Published: August 2021

RESUMO O título “Os professores depois da pandemia” chama a atenção para a necessidade de mudanças profundas na educação e no trabalho docente. O texto parte de uma crítica a três ilusões correntes, acentuadas pela resposta à Covid-19, que difundem as ideias de que as aprendizagens acontecem “naturalmente” numa diversidade de tempos e ambientes, de que a escola física vai dar lugar à “escola virtual” e de que a pedagogia pode ser substituída pelas tecnologias. Em alternativa a essas “ilusões”, sublinhamos que a educação implica sempre uma intencionalidade, o que nos conduz a valorizar o papel dos professores na construção de um espaço público comum da educação, na criação de novos ambientes escolares e na composição de uma pedagogia do encontro.
Resiliência pedagógica: escolas ribeirinhas frente às variações de seca e cheia do Rio Amazonas
Authors: Alencar Danielle Golvim da Silva , Costa Francimara Souza da
Published: August 2021

Resumo Resiliência pedagógica pode ser compreendida como uma estratégia que viabiliza de maneira prática e qualitativa a adaptação do professor às situações adversas que surgem em seu ambiente de ensino, principalmente em realidades educacionais não convencionais, como aquelas vivenciadas por escolas localizadas nas margens dos rios da Amazônia. Este estudo objetivou analisar o processo de resiliência pedagógica de professores de uma escola ribeirinha localizada no município de Careiro da Várzea, Estado do Amazonas, considerando três fatores básicos: a formação do professor, o currículo escolar e as práticas educacionais realizadas. Para a realização da pesquisa foi utilizada a abordagem qualitativa e os dados foram coletados por meio de análise documental, pesquisa bibliográfica e entrevistas com professores e gestora da escola. Os resultados demonstram que o currículo escolar possui estrutura semelhante ao currículo de escolas urbanas, mas os professores tentam adaptá-lo à sua realidade, ainda que de forma parcial. Foi observada a ausência de uma formação específica para atuação dos professores na educação ribeirinha e a necessidade de um processo de adaptação constante das práticas educativas, de acordo com a sazonalidade de seca e cheia do Rio Amazonas. Tais necessidades resultam em reelaborações curriculares e de planejamentos, mudanças sazonais de estratégias de aulas e criação de práticas, além da necessidade de adaptação do ambiente escolar à falta de material e de infraestrutura adequada.

Determinants and Cheeger-Müller Theorem on even dimensional projective spaces
Authors: Rafael F. S.
Published: August 2021

We establish formulae for the regularized determinant of the Laplacian and twisted Laplacian on forms over even dimensional real projective spaces and use them to explicitly calculate the analytic torsion of these spaces with orthogonal and unitary representations of their fundamental group, obtaining the first example to show that this torsion is non-trivial for cyclic complexes associated to even dimensional non-orientable manifolds. Moreover, as discussed in the introduction, the several proofs of the Cheeger-Müller Theorem given throughout years left one specific question unanswered and we answer this question for this type of space.

Authors: Заблоцкая Татьяна Юрьевна
Published: August 2021

В статье рассматривается проблема идентификации параметров феноменологической модели Боука — Вена, описывающей работу широкого круга нелинейных систем с гистерезисом при помощи дифференциальных уравнений. Параметры классической модели Боука — Вена анализируются с точки зрения их влияния на форму петли гистерезиса. Приводится классификация диссипативности модели в зависимости от диапазона значений параметров. Дается аналитическое описание входного сигнала, исходя из задачи использования модели Боука — Вена в качестве гистерезисного преобразователя, встроенного в искусственную нейронную сеть на базе биологического нейрона. Описывается процедура определения параметров нормализованной модели, основанная на идентификации предельного цикла в уравнениях, описывающих петлю гистерезиса. Анализируется соответствие между параметрами исходной и нормализованной моделей Боука — Вена, а также влияние каждого из параметров в отдельности на форму гистерезисной кривой. Получены аналитические зависимости, определяющие параметры нормализованной модели на основе анализа входно-выходных соответствий модели Боука — Вена. Предложен алгоритм вычисления параметров Боука — Вена. Теоретические выкладки иллюстрируются результатами вычислительных экспериментов.

Published: August 2021

В основе любых криптографических алгоритмов и протоколов используются простейшие функции — перестановки и подстановки элементов заданного конечного множества. Объединяя и трансформируя данные элементы, организуется структурная ячейка защиты информации — атематическое преобразование, обладающее необходимой криптографической стойкостью. Главная проблема в выработке таких преобразованиях заключается в том, что в процессе формирования более мощных алгоритмов разработчики используют все больше данных и вычислительных мощностей, полагаясь при этом на аппаратные возможности информационной системы. Это не только увеличивает потребление ресурсов, но также ограничивает скорость и конфиденциальность приложений. Однако изучая математические аспекты формирования перестановок и систему счисления рядов факториальных множеств необходимо перейти к активному изучению проблемы накопления данных, чтобы предложить новые алгоритмы, которые уменьшают модели аппаратного хранения больших объемов перестановок без потери возможностей. Система счисления ряда факториальных множеств позволяет использовать алгоритм формирования любого элемента факториального множества без хранения перестановок в оперативной памяти. Таким образом, функция хранения массивов данных для криптографических алгоритмов уже не является необходимостью, так как ее функциональные возможности заменяет использование алгоритма формирования перестановок из системы счисления рядов факториальных множеств. В работе рассматриваются аксиомы и способы построения подгрупп симметрических групп подстановок ряда факториальных множеств. Новые понятия ряда факториальных множеств и симметрических групп подстановок ряда факториальных множеств, введенные в 2014 г., позволяют расширить возможности анализа симметрических групп подстановок, позволяют их нумеровать, идентифицировать, структурировать и сделать более наглядными процессы группового и индивидуального преобразования. В работе приведен вариант классификации подгрупп по способам их построения.

Развитие информационных технологий предполагает непрерывное совершенствование средств, обеспечивающих обработку и преобразование конфиденциальных данных. Решение подобных задач в масштабе реального времени предполагает совершенствование методов обработки потоковых данных, а также оценку их быстродействия. В статье рассмотрена математическая модель метода преобразования данных, основанная на идее клеточного автомата с плавающим окном. Для исследования быстродействия процесса обработки конфиденциальных данных разработан вариант организации структуры программного модуля с расширенным блоком настроечных параметров, включающим строку активации битовой окрестности обрабатываемых элементов, правило расширения граничных элементов матрицы, определяющее в зависимости от шага работы алгоритма положение соседей обрабатываемого элемента. В статье предложен метод формирования графической зависимости внесенных изменений, косвенно отражающий стойкость метода шифрования и выявляющий соответствие результатов доверительному интервалу. На основе проведенных исследований разработан программный модуль, на базе которого реализовано правило, учитывающее состояние соседних блоков данных для обрабатываемого элемента. Предложенный в статье вариант обработки потоковых данных на базе клеточных автоматов с использованием вычислительных кластеров позволяет оптимизировать скорость обработки потоков данных за счет предварительного этапа оценки соответствия текущего блока пользовательскому шаблону. Использование данного варианта обработки не привело к выходу из доверительного интервала, а распределение бит осталось близким к случайному. В статье проведены экспериментальные исследования на базе разработанного программного модуля, реализующего метод преобразования данных, основанный на идее клеточного автомата с плавающим окном, которые подтвердили полноту и корректность полученных результатов.

Published: August 2021

Работа посвящена вопросам разработки и внедрения программ дополнительного профессионального образования с использованием инновационных технологий и цифровых ресурсов. Актуальность рассматриваемой темы обусловлена необходимостью реализации принципа непрерывности образования в условиях активного развития и внедрения новых производственных технологий в практическую деятельность промышленных предприятий. Как следствие наблюдается активный рост необходимости формирования качественных знаний. При этом традиционные инструменты не подходят для создания специализированных программ дополнительного профессионального образования, поскольку ведут к потерям времени и ресурсов. Остро встает вопрос о качестве предлагаемых программ дополнительного профессионального образования, содержание которых зачастую определяется разработчиками интуитивно, без учета эффективных способов, методов и систем обучения. В сфере повышения квалификации дипломированных специалистов необходимо создание образовательной платформы и выстраивание образовательного процесса с учетом интересов заказчиков, разработчиков и конечных потребителей программ дополнительного профессионального образования. Отсутствие обоснованного подхода к формированию содержания программ дополнительного профессионального образования в отечественной практике обуславливает новизну предлагаемого решения. Авторами показана значимость использования принципов педагогического дизайна, представлены результаты анализа его различных современных технологий, особенностей выполнения их этапов и областей применения. Обоснован выбор усовершенствованной технологии ADDIE для формирования качественного контента программы дополнительного профессионального образования, с целью передачи требуемой информации в наиболее понятной конечному потребителю форме. Анализ процесса разработки и внедрения программ дополнительного профессионального образования выполнен с позиций системного подхода, что позволило смоделировать процесс разработки концепта образовательной программы и сформировать комплекс функциональных моделей, облегчающих качественную разработку и взаимодействие заказчиков и разработчиков программ.

В статье предлагается подход к реализации начального этапа решения задачи поиска и назначения оптимальных стратегий лечения пациентов с помощью моделей обучения с подкреплением, состоящего в выделении основных групп состояний пациентов с диагностированным атеросклерозом с использованием кластерного анализа. В качестве исходного набора данных была использована выборка MIMIC-III, содержащая значения клинических, лабораторных, гемодинамических и др. показателей пациентов. Основным методом кластерного анализа в данной работе был выбран метод k-medoids, при этом качество кластеризации оценивалось с помощью силуэтного анализа. Предварительным этапом кластеризации являлось понижение размерности с помощью метода главных компонент (PCA), а визуализация результатов производилась с помощью метода t-SNE. При этом важным этапом данного исследования являлось вычисление оценки тяжести состояния пациента для каждого из выявленных кластеров состояний. Полученные оценки используются для вычисления вознаграждений в модели назначения оптимальных схем лечения с помощью методов обучения с подкреплением, при этом набор полученных кластеров определяет набор состояний окружения. Таким образом, результаты кластеризации позволяют выявить основные закономерности в исходном наборе данных, а также позволяют сформировать основные составляющие модели обучения с подкреплением для назначения оптимальных схем лечения атеросклероза.

Authors: Iermakov Sergii , Khudolii Oleg , Chupikhin Denys
Published: August 2021

The aim of the study was to determine the impact of the number of repetitions on the effectiveness of teaching boys aged 7 throwing a small ball. Materials and methods. The study participants were 27 boys aged 7, who were randomly divided into three groups of 9 people each. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The study examined the impact of the number of repetitions on the effectiveness of teaching boys aged 7 throwing a small ball at a target. A pedagogical experiment studied the impact of 6, 12, and 18 repetitions with a 60-second rest interval on the increase in the level of proficiency in exercises of boys aged 7. In the first group, the boys repeated the task 6 times with a rest interval of 60 s, in the second group – 12 times with a rest interval of 60 s, in the third group 18 times with a rest interval of 60 s. When teaching throwing exercises during the class, the study assessed the level of proficiency by the alternative method (“performed”, “failed”) and calculated the probability of exercise performance (p = n/m, where n is the number of successful attempts, m is the total number of attempts). In teaching boys aged 7, the method of algorithmic instructions was used. The next exercise started after three successful attempts. Throwing a ball at a vertical target was taught. The study materials were processed by the IBM SPSS 20 statistical analysis software. During discriminant analysis, a prognostic model for group membership was created. Results. Discriminant analysis made it possible to determine the impact of the number of repetitions on the effectiveness of developing the skills of throwing a small ball at a target; to answer the question as to how significantly the modes of repetition differ by the effectiveness of motor skills development, to which class the object belongs based on the values of discriminant variables. Conclusions. Based on the analysis of group centroids, it was found that 12 repetitions of the exercise (6 sets 2 time each with a rest interval of 60 s) significantly influence the increase in the level of proficiency in physical education classes. The results of group classification show that 94.4% of the original grouped observations were classified correctly.
Attitudes and the (dis)continuity between memory and imagination
Authors: Sant'Anna André
Published: August 2021

The current dispute between causalists and simulationists in philosophy of memory has led to opposing attempts to characterize the relationship between memory and imagination. In a recent overview of this debate, Perrin and Michaelian (2017) have suggested that the dispute over the (dis)continuity between memory and imagination boils down to the question of whether a causal connection to a past event is necessary for remembering. By developing an argument based on an analogy to perception, I argue that this dispute should instead be viewed as a dispute about the nature of the attitudes involved in remembering and imagining. The focus on attitudes, rather than on causal connections, suggests a new way of conceiving of the relationship between memory and imagination that has been overlooked in recent philosophy of memory.
Not Without Their Hijab: Being a Muslim Female Student at A Mid-Southern University
Authors: Mrayan Suhair A , Saleh Amany I
Published: August 2021

Scholars might agree or disagree on the best definition of Islamophobia, but no one can deny Islamophobia is a very real and dangerous phenomenon in American society. This research examined veiled Muslim students’ experiences and perceptions of a typical American university campus in the aftermath of the most recent terrorist attacks. The findings demonstrated that students perceived the campus community to be tolerant and welcoming. On the other hand, students reported off-campus incidents that speak of ignorance and intolerance of Muslim students.  The study provides higher education institutions with insights on how to increase cultural awareness on-and-off campus to correct stereotypes and make Muslim students feel welcomed in their communities. The authors hope to create awareness among students and community members; thereby helping to debunk the stereotypes, and creating a safe and diverse campus for all students. Educators and college leaders can use this knowledge to combat stereotypes and biases; thus making campus a safer and more welcoming environment for all students.

Published: August 2021

Introduction. In Mexico, alcohol consumption is the main problem related to substance use among university students. Objective. To analyze emerging alcohol consumption patterns in students at a public university through the administration of an online survey. Method. This is a cross-sectional, survey-based study. Participants included 3,888 students from a large university in Mexico City, to whom the alcohol and sociodemographic data section of the Cuestionario de Estudiantes 2014 was electronically administered in August-September 2018 and 2019. Latent Class Analysis was applied to the data obtained. During the research, the principles, norms, and ethical precepts of research on human beings were observed. Results. The relevant variables observed were length of exposure to alcohol, excess alcohol consumption, consumption on a typical day and alcohol-related consequences, which were used to create a model with four groups: teetotalers and early drinkers without consequences, risky drinkers with consequences, experienced risky drinkers without consequences and habitual drinkers with consequences. 36.7% of the sample were classified into groups with consequences and a high likelihood of excess consumption. Discussion and conclusion. Lengthy exposure to alcohol influences measures of frequency and intensity of consumption in relation to the number of consequences suffered. This latent class model can guide the design and priority of universal, selective, or suggested preventive interventions.
THE IMPACT OF VOLUNTEERING AIMED AT HELPING THE COMBATANTS AND VICTIMS OF THE WAR, ON VOLUNTEERS’ FAMILY WELL-BEING
Authors: Klymenko I. V.
Published: August 2021

In the article, we have analyzed the information that concerns the potential impact of volunteer activity on the psycho-emotional state and the family well-being of volunteers, in particular those who carry out their activities in extreme conditions.
We have analyzed the peculiarities of the activities of Ukrainian volunteers who assisted the combatants and victims of the war during the most fierce military confrontation in the East of Ukraine in 2014– 2016 and found that their activities could have a negative impact on the socio-psychological climate and the functioning of their families due to prolonged, tensional, emotionally intense and sometimes risky nature of activities.
We have researched the peculiarities of matrimonial relationship and some indicators of family well-being (level of satisfaction with marriage and marriage partner, peculiarities of communication, readiness for interaction, level of mutual respect and emotional attraction) in the families of active participants of the volunteer movement, who directed their efforts to assist the military and civilian during a period of active military confrontation.
We have analyzed the correlation between the family well-being of volunteers and the peculiarities of their activities. Particular attention was paid to the analysis of the specifics of activities and relationships with marital partners for volunteers whose families eventually have broken up (every fifth of studied participants have experienced a divorce during active engagement in volunteering).
The indicators of the psycho-emotional status of volunteers (fixation and somatization of anxiety, depression) were also analyzed.
We have identified a number of factors that can negatively affect the family well-being and the psycho-emotional state of volunteers who operate in conditions of military confrontation, in particular the intensity and duration of volunteering activity, significant personal responsibility, high emotional involvement, lack of support from family members.
Research on the Application of Machine Learning Algorithms in Credit Risk Assessment of Minor Enterprises
Authors: Mi Huichao
Published: August 2021

Under the influence of COVID-19, minor enterprises, especially the manufacturing industry, are facing greater financial pressure and the possibility of non-performing loans is increasing. It is very important for financial institutions to reduce financial risks while providing financial support for minor enterprises to promote industrial development and economic recovery.

Authors: Xiulan Meng Xiaohua Yu,
Published: August 2021

By introducing knowledge sharing as an intermediary variable and using 375 questionnaires, this paper makes an empirical study on the intrinsic motivation, the main and mediating effects of knowledge sharing on individual innovation behavior. The results show that: (1) The intrinsic motivation has a positive predictive effect on individual innovation behavior, and the influence degree of each dimension on individual innovation behavior is beta interest > beta competency > beta curiosity > beta self-determination > beta work engagement. (2) The intrinsic motivation has a positive predictive effect on knowledge sharing. Besides self-determination, all dimensions of intrinsic motivation can actively promote knowledge sharing among employees, such as competency, work engagement, curiosity and interest. (3) Knowledge sharing has a partial mediating effect on the relationship between internal motivation and individual innovation behavior of knowledge-based employees in the industrial new generation. Knowledge sharing plays a mediating role in the influence of competency, work engagement, curiosity and interest on individual innovation behavior, but does not have a mediating effect on self-determination. The conclusions of this study can provide reference and suggestions for enterprises to effectively promote individual innovation of the industrial new generation of employees.
In vitro Antioxidant and Antibacterial Activities of Quinoa Flavonoids Extracted by Ethanol-Ammonium Sulfate Aqueous Two-Phase System
Authors: Wu Xiaoyong
Published: August 2021

Quinoa (Chenopodium quinoa Willd.) is a functional and ideal food for human nutrition and an Andean seed-producing crop. In this study, ultrasonic-assisted extraction of total flavonoids in Quinoa with ethanol (C2H5OH)-ammonium sulfate ((NH4)2SO4) aqueous two-phase system was performed based on the Box-Behnken experimental design principle. The highest extraction rate of TFQ under the condition of 28% C2H5OH -14% (NH4)2SO4 aqueous two-phase extraction system was used to analyze the variance of TFQ extraction rate as the response value. The multiple quadratic linear regression equation was obtained by a three-factor three-level response surface method. The extraction rate= 74.28+1.78 A+0.10 B+0.38 C+0.20 AB+0.05 AC+0.05 BC+1.000E-002 A2-0.94 B2-0.69 C2. The response surface analysis showed that the best extraction conditions of aqueous two-phase were the crude TFQ mass fraction 20.6%, pH 7.18, NaCl mass fraction 2.23% and the maximum value predicted by the extraction rate model was 75.929 3% (P=0.994). The average extraction rate of TFQ was 75.3%, according to the optimal two-aqueous phase extraction conditions. The ETFQ has varying degree of scavenging effect on hydroxyl radical, oxygen free radicals, nitrite and ·ABTS+ compared with vitamin C. Among them, the scavenging effect of the ETFQ on hydroxyl radical, oxygen free radicals and ·ABTS+ was greater than vitamin C, except nitrite. Also, the ETFQ has the strongest inhibitory effect on E. coli and Bacillus subtilis, and the inhibitory rate can reach up to high dose 97.59 and 98.44%, MIC is 1.56 mg/mL; the second is the inhibition of S. aureus, MIC is 6.25 mg/mL. It has the weakest inhibitory effect on Salmonella. The antibacterial rate was positively correlated with the ETFQ mass concentration. The results help to discover the medicinal effects of quinoa in addition to nutrition to carry out more in-depth research and increase economic value. © 2021 Friends Science Publishers
Virus-induced Silencing SBEIIa and SSIIa, Alone or Together, Increased the Amylose and Resistant Starch Contents in Spring Wheat
Authors: Li Zhaofeng
Published: August 2021

Foods rich in amylose and resistant starch (RS) have great potential to improve human health and lower the risk of noninfectious diseases. Common wheat (Triticum aestivumL.) is a major staple food crop with low RS content in the grains. The content of RS, preferentially derived from amylose, may be increased by suppressing amylopectin synthesis viasilencing the starch branching enzyme (SBE) II a or/and starch synthase (SS)IIa. In this study, SBEIIaand SSIIawere silenced separately and simultaneously using a barley stripe mosaic virus-virus-induced gene silencing (BSMV-VIGS) system. Compared with grains from control BSMV:00-inoculated spikes, grains from BSMV:SBEIIa-and BSMV:SSIIa-infected spikeshad fewer SBEIIa and SSIIa transcripts,together with increased amylose contents (18.62 and 24.48%, respectively) and RS contents (11.61 and 16.67%, respectively). Infection with BSMV:SBEIIa-SSIIa reduced SBEIIa and SSIIatranscript levels and increased the amylose and RS contents (32.02 and 22.33%, respectively). Thus, BSMV-VIGS is a useful tool for the rapid silencing of single or multiple starch synthase-related genes and BSMV shows great potential to study the functions of genes involved in starch biosynthesis or other processes/traits in developing grains.We showed that the SSIIagene plays an important role in the synthesis of amylose and RS and that the effects of simultaneously silencing SBEIIaand SSIIaon starch synthesis aregreater than those of single gene silencing. Our study lays the foundation for the molecular design-based breeding of high-amylose and high-RS wheat.© 2021 Friends Science Publishers

Root Traits Responses to Irrigation Intervals in Rice (Oryza sativa)
Authors: Gaballah Mahmoud M.
Published: August 2021

Drought is one of major abiotic stresses that effect rice production. Roots play vital role in absorption of water and nutrients from soil contributing for drought tolerance. The present study quantified the effects of different irrigation intervals on root development and agronomical traits of three Egyptian rice cultivars, Giza177, Giza178, Sakha107, IET1444 as a popular drought tolerant and Moroberekan as control genotype. Irrigation treatments were imposed 15 days after transplanting and applied for every 4, 8 and 12 days during 2018 and 2019 rice growing seasons. The results showed the reduction in root architecture traits with prolonged irrigation intervals. A significant decrease in plant height, number of panicles plant-1, grain yield (t ha-1) and relative water content, while sterility (%) and water use efficiency significantly increased over irrigation intervals. The highly significant and positive correlation was found among grain yield and root:shoot ratio, relative water content and number of panicles plant-1, while the negative correlation was with root xylem vessel number and sterility. It was concluded that, the drought reduced the grain yield and its components due to poor developed root system. Moroberekan and IET1444 genotypes can be used as a donor parent for rice breeding program. Further studies are also required to identify factors that contribute to the high yield potential of both Giza178 and Sakha107 under different water stress condition. © 2021 Friends Science Publishers
