Published: March 2021

The main objective of this research was to explore the potential antibacterial activity of 25 selected medicinal plant extracts against four strains of bacteria. The ethnomedicinal knowledge was documented using semi-structured, open-ended questionnaires, informal interviews, and group discussions with traditional healers and knowledgeable persons about plants and plant-based remedies. The evaluation of antibacterial activities of twenty-five extracts of different plants was carried out by adopting the disc diffusion method for four bacterial strains, namely - Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis and Staphylococcus aureus. The results were reported by observing the inhibition zones. The results indicated that among 25 plant extracts examined, 16 (64%) plant extracts showed antibacterial property against Escherichia coli followed by 15 (60%) plant extracts against Pseudomonas aeruginosa, and 19 (76%) extracts each against Staphylococcus aureus and Bacillus subtilis. Four plant extracts were not able to produce the zone of inhibition with any of the tested bacteria. Gram-positive bacteria are found to show more positive effects as compared to Gram-negative. Present findings of this study indicate that ethnomedicinal plant extracts have antibacterial activity against the different strains of tested bacteria. This activity supports their use in the treatment of infections caused by such resistant bacteria.
Mathematical modeling applied to ruminal digestion and gas production in vitro
Authors: Assis J. R. , Assis A. C. M. , Fernandes G. A.
Published: March 2021

The ruminal digestion performed by ruminants is one of the essential and most important processes for the use of dietary nutrients. However, the use of mathematical models applied to digestion kinetics has been widely applied to provide prediction of animal performance, maximize the use of nutrients and reduce nutritional losses due to excreta and a reduction in the cost of animal production. In this context, it aimed to conduct a literature review on the use of mathematical models and to analyze comparisons of different models to predict ruminal digestion. The in vitro gas production technique provides direct measurement of the ruminal digestion rate associated with gas production and the respective gravimetric measurement of the food or diet under test. Nonlinear models are chosen to evaluate ruminal digestion due to a better interpretation of biological parameters, they produce exponential and sigmoidal growth equations. However, the most suitable model for evaluation depends on the type of food or diet. The two-compartment logistical model presents a better adjustment of the gas production curve, mainly for foods with a high proportion of fiber. Among this, single-compartment models can be well applied to evaluate the degradation kinetics of foods with low fibrous carbohydrate content. Therefore, the choice of the most appropriate model is up to the researcher to assess which model best suits the chemical-chemical composition of the food or diet.

Fostering Group Autonomy Through Collaborative Learning in an Online Environment
Authors: Zhong Qunyan Maggie
Published: March 2021

Learner autonomy is recognised as being associated with effective and successful learning. Whilst significant scholarship has focused on individual learner autonomy, a review of the literature indicates that the interdependence and social dimension of learner autonomy are largely under-researched. The primary objective of this study is to examine how learners engaged in a collaborative inquiry outside the classroom utilising an asynchronous online discussion forum and to what extent the collaborative task fostered group autonomy. Employing thematic analysis, postings of 20 students in a peer-moderated online discussion forum were analysed. The results revealed that the process of knowledge co-construction advanced and deepened the learners’ understanding of the subject matter. Furthermore, the collaborative inquiry helped establish a community of learning whereby students supported each other emotionally and cognitively, and they wanted to achieve well collectively. The study concluded that a well-designed collaborative task is key to fostering the social and interdependent dimension of learner autonomy.

Local stiffness and work-function variations of hexagonal boron nitride on Cu(111)
Authors: Grewal Abhishek , Wang Yuqi , Münks Matthias , Kern Klaus , Ternes Markus
Published: March 2021

Combined scanning tunnelling and atomic force microscopy using a qPlus sensor enables the measurement of electronic and mechanic properties of two dimensional (2D) materials at the nanoscale. In this work we study hexagonal boron nitride (h-BN), an atomically thin 2D layer, that is van der Waals coupled to a Cu(111) surface. The system is of interest as a decoupling layer for functional 2D heterostructures due to the preservation of the h-BN bandgap and as a template for atomic and molecular adsorbates owing to its local electronic trapping potential due to in-plane electric field. We obtain work-function (Φ) variations on the h-BN/Cu(111) superstructure in the order of 100 meV using two independent methods, namely the shift of field emission resonances (FER) and contact potential difference (CPD) measured by Kelvin probe force microscopy (KPFM). Using 3D force profiles of the same area we determine the relative stiffness of the Moir\'e region allowing us to analyze both electronic and mechanical properties of the 2D layer simultaneously. We obtain a sheet stiffness of 9.4 ± 0.9 nm which is an order of magnitude higher than the one obtained for h-BN/Rh(111).Using constant force maps we are able to derive height profiles of the h-BN/Cu(111) showing that the system has a corrugation of 0.6 ± 0.2 Å which helps demystify discussion around the flatness of the h-BN/Cu(111) substrate.

Study of parallel operation of diesel generators ship power plant
Authors: Popov Sergey V. , Burmakin Oleg A. , Malyshev Yuriy S.
Published: March 2021

Analysis of the power plants of a number of passenger ships showed the need to ensure the parallel operation of generators previously operating separately. The installed DGs are intended only for autonomous operation, which do not imply the introduction of statism into the characteristics of the generators. The aim of the work is to ensure the working condition of the ship power plants in accordance with the current requirements of the Russian River Register (RRR), which imply stable parallel operation of the diesel generator. As a result of the operation of the installed diesel engines, the complexity of precise control of the mechanical characteristics was determined, associated with the specifics of the operation of the mechanical frequency controllers installed on the engines. To determine the quality of mechanical RFI, functional and structural diagrams of the system for stabilizing the frequency of rotation of a drive motor with a mechanical regulator were developed, on the basis of which the transfer function was obtained and a conclusion was made about the instability of the regulator at large values of backlash in the mechanical transmission. Achieving this goal is possible by replacing the mechanical RFI with an electronic one with an actuator, which is confirmed by a mathematical analysis of the corresponding control systems. The transfer functions of control systems are obtained on the basis of the developed structural and functional models. Electronic controllers, made according to the presented schemes, have been introduced on a number of marine diesel generator sets and have shown a positive result. As a result of the study of the operation of the new system, the optimal parameters of the regulator settings were determined, at which the required dynamic and static characteristics were obtained. The failure-free operation of the system has been confirmed by long-term tests with the vessel operating in normal mode throughout the navigation.

The goal of the paper is to determine the role and place of the proposed method in the development of sea passenger traffic and island tourism in the Socialist Republic of Vietnam and to illustrate its capabilities in relation to the interests of different participants of process. As a rule, the existing ships are purchased on the secondary market, and new ones are often designed and built at foreign shipyards. This is a reason to develop the design methods that take into account the regional characteristics of Vietnam. The novelty of this research is based on the fact that the proposed method takes into account the regional features, combines mathematical and optimization models of various design levels and allows to take into account the interests of participants of a program for development of maritime transport infrastructure and tourism in Vietnam. The theoretical principles of ship theory, ship design, mathematical programming and statistics were used for the method development.

In this paper we present the results of design characteristics optimization of high-speed passenger catamarans and comparative analysis of these results with the main dimensions of modern high-speed passenger catamarans. The proposed method can be used in the design and assessment of the economic efficiency of high-speed passenger catamarans. The results can be used in Vietnam government program oriented to development of sea transport infrastructure and tourism.

Published: March 2021

O objetivo do presente estudo foi identificar os riscos cardiovasculares em adolescentes estudantes do Ensino Médio de uma escola pública da cidade de Anápolis-GO. Trata-se de um estudo transversal de caráter quantitativo. A população foi composta por um total de 567 alunos de ambos os sexos, selecionados aleatoriamente com idade entre 14 e 17 anos. Para os riscos cardiovasculares foram coletados o Índice de Massa Corporal (IMC); Pressão Arterial (PA) e Circunferência de Cintura (CC). Foram feitas as análises de correlação entre as variáveis por meio do teste de correlação de Pearson e uma comparação entre turmas por meio do teste Crosstabs. Os resultados obtidos na avaliação de correlação das variáveis demonstraram relação positiva entre peso/altura, CC/PAS, demonstrando que adolescentes mais altos e com sobrepeso têm maior risco para doenças cardiovasculares, quando feita uma comparação entre as turmas estudadas. O 1º ano teve destaque devido possuir o maior número de adolescentes com valores de IMC, PAD e CC. Concluiu-se que adolescentes com maior peso e altura têm maiores chances de desenvolver doenças cardiovasculares e adolescentes mais altos podem apresentar alteração na PAD.
Factors of Development of Hybrid Institutional Agreements in Traditional Societies
Authors: Sitkevich D. A.
Published: March 2021

This paper analyzes the reasons why hybrid organizations appear in some traditional communities, but not in others. For this purpose, a field study was conducted in three villages in Dagestan, where there is different dynamic of cooperation between local entrepreneurs. The interviews show that the main factors in the development of hybrid organization are the presence of closed social capital, informal regulators within the community, the presence of demand for community products in foreign markets, and the ability of local entrepreneurs to borrow know-how from outside the community. In addition, the following barriers to the development of hybrids were identified: low quality of the institutional environment, differences in the approach to doing business among community residents, and rural depopulation.

The diversity of human identities in the context of pluralism is essential. However, differences are often seen as something "stranger" and unfriendly, especially in socio-religious relations context. In a plurality of society, the church must be able to place itself in social relations, especially in treating "strangers." This article aimed to offer an approach and theme of hospitality in teaching people or members of the congregation, whether in church, family, or school. Using a qualitative literature approach, applying the interpretive descriptive method, and argumentative comparisons, it is concluded that the hospitality of Christian education is the value for carrying out the law of love in social relations amidst diverse identities.AbstrakKeberagaman identitas manusia dalam konteks pluralisme adalah hakikat. Namun, perbedaan tidak jarang dipandang sebagai sesuatu yang “asing” dan tidak bersahabat, terlebih dalam konteks relasi sosial-agama. Gereja di tengah masyarakat yang pluralitas harus mampu menempatkan diri dalam relasi sosial, terlebih dalam memperlakukan “yang asing”. Artikel ini menawarkan sebuah pendekatan dan tema hospitalitas dalam mengajarkan umat, atau anggota jemaat, baik di gereja, keluarga, maupun sekolah. Dengan menggunakan pendekatan kualitatif literatur, dan menerapkan metode deskriptif interpretatif, dan komparasi argumentatif, disimpulkan, bahwa hospitalitas pendidikan Kristiani merupakan value untuk melakukan hukum kasih dalam relasi sosial di tengah keberagaman identitas.
Socioeconomic determinants of demographic development of the Yamalo-Nenets Autonomous Okrug
Authors: Barkova Ekaterina R.
Published: March 2021

The study explores the peculiarities of demographic processes in the Yamalo-Nenets Autonomous Okrug and the socioeconomic factors determining them. The author tests hypotheses about the relationship of socioeconomic characteristics of the population with fertility and migration basing on data from 13 municipalities of the region for 2011–2017. The analysis reveals a statistically significant relationship between age-specific fertility rate for women aged 15–49 and such indicators as marriage and divorce rates, wages, the proportion of employed in the working-age population, the enrolment of children in preschool education, and the proportion of families who received housing or improved housing conditions among those registered in the housing program. Inbound migration rate is statistically related to wages, as well as to proportion of employed in the total working-age population, while outbound migration rate is linked to proportion of those employed in mining, as well as to indicators characterizing situation in the marriage market.

Published: March 2021

In this paper, let \begin{document}$ \mathcal{A} = (a_{i_1 i_2 \cdots i_m } )\in{\mathbb{R}}^{[m, n]} $\end{document}, when \begin{document}$ m\geq 4 $\end{document}, based on the condition \begin{document}$ ||x||_2 = 1 $\end{document}, a new \begin{document}$ Z $\end{document}-eigenvalue localization set for tensors is given. And we extend the Geršhgorin-type localization set for Z-eigenvalues of fourth order tensors to higher order tensors. As an application, a sharper upper bound for the Z-spectral radius of nonnegative tensors is obtained. Let \begin{document}$ \mathcal{H} $\end{document} be a \begin{document}$ k $\end{document}-uniform hypergraph with \begin{document}$ k\geq 4 $\end{document} and \begin{document}$ \mathcal{A}(\mathcal{H}) $\end{document} be the adjacency tensor of \begin{document}$ \mathcal{H} $\end{document}, a new upper bound for the Z-spectral radius \begin{document}$ \rho (\mathcal{H}) $\end{document} is also presented. Finally, a checkable sufficient condition for the positive definiteness of even-order tensors and asymptotically stability of time-invariant polynomial systems is also given.
The Intervening Prince: Althusser, Foucault, and a Theory of Strategy
Authors: Mesing Dave
Published: March 2021

This paper stages an encounter between Foucault and Althusser on the question of strategy. By contrasting a few passages in La Volonté de savoir with some of Althusser’s writings on Machiavelli and Lenin, I propose an alternative between the two thinkers according to a schema of strategic thought (Foucault) and a philosophy for strategy (Althusser). This narrow focus enables me to generate a working definition of strategy as the anticipation of an encounter which modifies, abolishes, or otherwise alters the relations constituting its conjuncture. By staging the encounter between the Foucault and Althusser, I propose this definition as a reflection on the phrase “intervention into conjuncture,” and conclude by sketching implications concerning theory, practice, and the discipline of the conjuncture.
The Truth of the Work of Art: Freud and Benjamin on Goethe
Authors: Espinoza Tania
Published: March 2021

Juliet Mitchell’s psychoanalytic account of sibling rivalry, fluctuating between narcissistic identification (love) and fear of annihilation (hate), also applies to Walter Benjamin’s model of true love in his reading of Goethe’s Elective Affinities. This model is found in the utopian novella “The Curious Tale of the Childhood Sweethearts,” inserted within Goethe’s novel. By reducing the relationship between the novella and its framing narrative to an opposition between truth and semblance, Benjamin replicates in his reading the specular logic that is love’s obstacle. On the other hand, Freud’s analysis of an episode in Goethe’s autobiography can be said to retroactively operate what Mitchell calls “lateral castration,” for Freud compares the great writer to patients in analysis and thus establishes the necessary seriality that creates “space for one who is the same and different.” Still, and although elements of his own autobiography facilitate the construction of alternative scenarios, Freud exempts Goethe’s sisters from the position of rivals. Recognising “the sister” as earliest playmate, and object of hatred and narcissistic identification, like Mitchell does, might be the first step necessary for drawing a model of love for women as peers this side of utopia.
A Topological Reading of Ernesto Laclau
Authors: Sciamarella Denisse
Published: March 2021

This work proposes a reading of Laclau’s theory on populism using concepts from topology applied to dynamical systems. The analogical correspondences are established between the elements used in the reconstruction of a topological structure from data and categories such as discourse, hegemony, demand, empty and floating signifier, antagonism, and heterogeneity.
Teaching in the American Community College
Authors: Kent Carol Hittson
Published: March 2021

With increasing emphasis on accountability in higher education, the value of faculty professional development continues to gain traction across campuses. Prompted by growing accreditation, assessment, and accountability measures, higher education institutions must provide evidence of faculty compliance with requirements that are tied to professional development. This is as true for community colleges as well as for four-year institutions. External and internal pressures for continuous improvement in teaching necessitates institutional commitment to understanding faculty perceptions and acceptance of high-quality professional development. Community colleges need to gain faculty acceptance of and participation in professional development in order to achieve fidelity to institutional instructional goals and initiatives. This chapter investigates community college faculty buy-in and support for professional development and considers cogent and relevant literature related to faculty professional development within the contemporary American community college setting.
