Authors: Долгий Юрий Филиппович , Dolgii Yurii Filippovich , Шевченко Роман Иванович , Shevchenko R I
Published: October 2021

Асимптотическая устойчивость линейной периодической системы дифференциальных уравнений с последействием определяется расположением спектра бесконечномерного вполне непрерывного оператора монодромии. Аналитическое представление такого оператора удается получить только для систем специального вида. В численных методах используются конечномерные аппроксимации оператора монодромии. В работе исследуется предложенная Н. Н. Красовским процедура аппроксимации системы дифференциальных уравнений с последействием системами обыкновенных дифференциальных уравнений большой размерности. В гильбертовом пространстве состояний периодической системы с последействием построены конечномерные аппроксимации для оператора монодромии. Доказана теорема, что при росте размерности конечномерных приближений точность аппроксимации оператора монодромии увеличивается.

Authors: Звягин Виктор Григорьевич , Zvyagin Viktor Grigorevich , Казначеев Михаил Викторович , Kaznacheev Mikhail Viktorovich
Published: October 2021

В работе изучается предельное поведение слабых решений автономной модели движения нелинейно-вязкой жидкости, в ситуации, когда время стремится к бесконечности. А именно, для решений рассматриваемой модели установлено существование слабых решений на положительной полуоси, определено траекторное пространство, соответствующее решениям этой модели, и на основе теории траекторных пространств доказано существование вначале минимального траекторного аттрактора, а затем и глобального аттрактора в фазовом пространстве. Таким образом, оказывается, что каково бы ни было начальное состояние системы, описывающей рассматриваемую модель, с течением времени оно «забывается» и неограниченно приближается к глобальному аттрактору.

Published: October 2021

Рассматривается численный метод решения нелинейной краевой задачи для системы дифференциально-алгебраических уравнений с запаздывающим аргументом, имеющих предельные особые точки. Для численного решения краевой задачи применяется метод стрельбы. Значение параметра «пристрелки» вычисляется с помощью метода Ньютона. Рассматривается случай, когда задача является плохо обусловленной, вследствие чего метод может расходиться. В этом случае решение строится продвижением по наилучшему параметру, которым является длина кривой множества решений. Решение начальной задачи при каждом найденном значении параметра «пристрелки» вычисляется с помощью метода непрерывного продолжения по наилучшему параметру.

Classification of Punctures on Complete Flat Surfaces
Authors: Sağlam İsmail
Published: October 2021

We investigate the behavior of a complete flat metric on a surface near a puncture. We call a puncture on a flat surface regular if it has a neighborhood which is isometric to that of a point at infinity of a cone. We prove that there are punctures which are not regular if and only if the curvature at the puncture is $4\pi$. We classify irregular punctures of a flat surface up to modification equivalence, where two punctures are called modification-equivalent if they have isometric neighborhoods. We show that there are uncountably many modification-equivalence classes of punctures on flat surfaces.
Wildkatzen in der Manege : Das Mensch-Tier-Verhältnis im Zirkus
Authors: Hanke Sabine
Published: October 2021

Die Zirkusdressur von Wildtieren ist in Verruf geraten. In diesem Zusammenhang haben 24 EU-Mitgliedstaaten den Einsatz von Wildtieren in Zirkussen eingeschränkt, 20 von diesen haben zudem auch ein tatsächliches Verbot ausgesprochen. Deutschland gehört nicht zu diesen Ländern und hat bisher nur die Verabschiedung eines solchen Verbots in Aussicht gestellt.1 Im Juni 2021 ist dieses Vorgehen nun vorerst gescheitert und eine Ergänzung der Zirkusverordnung, die den Neuankauf von Wildtieren wie Großkatzen, Giraffen und Elefanten verbieten sollte, wurde im Bundesrat gekippt. Dies soll zum Anlass genommen werden, die Struktur und den Charakter dieses Mensch-Tier-Verhältnisses aus historischer Perspektive auszuleuchten und nach der tierischen Handlungsfähigkeit in diesem klar von Menschen definierten Raum zu fragen.
Deconstruction as a Functional Tool in Decolonizing Nigerian Educational System: A Biblical Response.
Authors: Isiorhovoja Osbert Uyovwieyovwe
Published: October 2021

The paper examines the role of deconstruction in the Nigerian educational system vis-à-vis its functionality to the growing needs and challenges be devilling the nation. Arguably, the content of the system has been commonly viewed sometimes as dysfunctional, tilted toward the needs of the colonial agenda. This phenomenon did only leave the endeavour handicapped but also totally reliant on foreign ideology; a system that estranged the people. The paper adopts hermeneutical, historical, and critical approaches to the phenomenon. From a biblical perspective, while searching for relevance, there has been the need to decolonize certain aspects which otherwise have alienated the people, with the aim of targeting functionality and acceptability among Africans. The need to contextualize a foreign curriculum that will bring about a total overhauling of the system to achieve a vibrant curriculum remains a necessity in order to service the needs of the people. As in the decolonisation exercise among biblical scholars, chances are that we can achieve a great feat in our nation’s education sector. It concludes by resounding that the present educational system is deconstructed with the aim of removing dysfunctional elements; with full integration of a rich indigenous knowledge base that serves the people’s uniqueness amidst conflicting curriculum, the government should be proud to introduce into the educational system a fresh idea that meets the needs as posited by biblical scholars.

Published: October 2021

In this paper, cyanidin-3-glucoside was isolated and purified from black rice, then enzymatic acylation with lauric acid to obtain cyanidin-3-glucoside lauryl ester. The structure of cyanidin-3-glucoside lauryl ester was characterized by liquid chromatography electrospray ionization tandem mass spectrometry and Fourier transform infrared spectroscopy. Then the potential proliferative effect on probiotics and inhibitory effect on harmful bacteria of cyanidin-3-glucoside and cyanidin-3-glucoside lauryl ester were studied in vitro. The effects of cyanidin-3-glucoside and cyanidin-3-glucoside lauryl ester on the composition of human fecal intestinal flora and its metabolic pathway were also analyzed through 16S ribosomal ribonucleic acid high-throughput sequencing and gas chromatography-mass spectroscopy, respectively. The results indicated that cyanidin-3-glucoside lauryl ester was better than cyanidin-3-glucoside in promoting the growth of B. adolescentis, B. infantis, L. thermophiles, and L. acidophilus as well as inhibiting the growth of S. dysenteriae, Y. enterocolitica, S. enteritidis, and S. typhi. Additionally, the proliferative effect of cyanidin-3-glucoside lauryl ester was significantly improved in a lower media pH due to the intestinal microbial metabolism to produce more organic acids, such as propionic acid, phenyllactic acid, and lauric acid. The study will provide a theoretical basis for the application of cyanidin-3-glucoside lauryl ester in the intestinal health.

A model of glacial tectonics, applied to the ice­pushed ridges in the Central Netherlands
Authors: Wateren Dick F. M. van der
Published: October 2021

During a detailed structural geological and geomorphological survey of ice-pushed ridges around the Gel­derse Vallei (centre of the Netherlands) several questions arose about the origin of these landforms.
The Gelderse Vallei is a Saalian glacial basin filled with younger sediments, 40 km long and up to 20 km wide, running NNW-SSE. Thrust sheets which build up the ice-pushed ridges on either side of the valley were transported away from the centre of the basin. They are up to 25 m thick and are pushed to a level about 100 m above the decollement. The thrust sheets, mainly consisting of coarse sand layers, moved as rigid masses, while only the finegrained basal layers deformed by heterogeneous simple shear.
Pore water pressure plays an important role by greatly reducing the sliding friction in the decollement layer. Once a glacial thrust sheet is formed, the weight of the upward moving frontal part (the toe) offers a resistance to movement, which can not be overcome by the basal shear stress of the glacier alone. Basal shear stresses in most glaciers are in the order of 0.1 MPa (1 bar) and appear to be incapable of lifting a toe of the size found in most ice-pushed ridges in the Netherlands.
The article presents a model of a system ice lobe - substratum, which is to a large degree controlled by gravitational forces.
The dilemma may be solved by the concept of the gradient stress field under the marginal area of an ice lobe. This concept was first formulated by Rotnicki (1976). Because ice thickness decreases towards the margin, the substratum is subjected to a decreasing load in the same direction. If the increments of stress difference under a slab of ice in the marginal zone are summed, a gradient stress is arrived at which is di­rected towards the ice edge.
An estimate of the forces involved in the static equilibrium around the glacier margin indicates that the contribution by the gradient stress field is sufficient to move the toe.
In the model proposed in the article, the energy to move and imbicate glacial thrust sheets around the margins of an ice lobe, is supplied by the continuous flow of ice into the ice lobe. The dimensions of ice­pushed ridges are thus to a high degree functions of the thickness of the ice lobe or icecap. The Gelderse Vallei ice lobe will have been at least 250 m thick to be able to form the ridges.
The basal shear stress contributes less to the tectonic transport, the larger the thrust sheets and the high­er the ice-pushed ridges.
Cupriferous pseudobrookite in a Tertiary basalt from the Faeroe Islands
Authors: Jensen Aage
Published: October 2021

Forty-five electron microprobe analyses have been carried out on pseudobrookite occurring in a basalt from the Faeroe Islands. It is shown that pseudobrookite formed after ilmenite contains between 1 and 3% CuO, whereas pseudobrookite formed after titanomagnetite does not contain Cu. This difference in Cu content is not inherited from the original ilmenite and titanomagnetite, but arises during the formation of the pseudobrookite.
The pseudobrookite in this basalt, regardless of whether it formed from ilmenite or from titanomagne­tite, is richer in Ti than in the formula Fe2TiO5, the surplus Ti4+ being balanced by the presence of divalent ions such as Mg, Mn, Fe and Cu. Mg and Cu dominate in pseudobrookite after ilmenite, Fe and Mg domi­nate in pseudobrookite after titanomagnetite. Pseudobrookite after titanomagnetite is richer in Ti than pseudobrookite after ilmenite.
The pseudobrookite is not homogeneous. Both pseudobrookite formed from ilmenite and that formed from titanomagnetite contain small blebs of hematite and rutile, and furthermore pseudobrookite after ti­tanomagnetite is intergrown with larger coherent areas of hematite. The hematite blebs in pseudobrookite after ilmenite can contain up to more than 5% CuO, but there is virtually no copper in either type of he­matite in the pseudobrookite after titanomagnetite, nor do the rutile blebs contain copper.

Chemotherapeutic intervention for cancer care is an important step. One of the most effective chemotherapy agents in use today is Paclitaxel (PTX), sold under the common name Taxol and Oxanol. Due to its ability to inhibit microtubule formation in cells, PTX is effective at all stages of the cancer and is FDA approved for treatment of many types of cancer (ovarian cancer, esophageal cancer, breast cancer, lung cancer, Kaposi sarcoma, cervical cancer, and pancreatic cancer). PTX is a plant alkaloid in the taxane family of compounds obtained from bark of the Pacific Yew tree (Taxus brevifolia) [1]. Adequate market supply of PTX has remained a challenge, as paclitaxel represents only a minor proportion of the total taxoid content of the Taxus species. Over the years, research into finding an alternate to cutting down Yew trees for PTX harvesting has been on the forefront. It is estimated that up to 60 trees may need to be harvested for the treatment of one patient.

The lens of vertebrates has a general structural plan and reacts similarly to various factors of anthropogenic impact. Rainbow trout (Oncorhynchus mykiss) and grass frog (Rana temporaria L.) are the most well-studied objects of aquatic toxicology in Russia, which react to the level of exposure to toxicants in the urbanized environment and retain the consequences of this exposure. The study aims to determine the possibility of using the lens of fish and amphibians as a biomarker of chronic and long-term background environmental contamination. The fundamental importance of the work lies in the fact that for the first time the mechanisms of the response of the epithelial cells of the eye lens and lens fibers to the spectrum of various toxicants entering the environment with industrial effluents are considered. In chronic experiments, the sensitivity of the lens of Oncorhynchus mykiss fingerlings to three toxicants (dibutyl sebacate-DBS, polyterpenes-PTP, and 3-aminopropyltriethoxysilane-AGM-9) in concentrations close to the normalized valuesin the environment was studied. On adult individuals of Rana temporaria, the appearance of abnormities in the lens was studied over a long period, depending on the total environmental contamination. To assess remote environmental contamination, studies were carried out on the constantly growing lens of the grass frog, which can preserve the resulting fiber abnormities throughout its life in the form of local opacities from the harmful environmental factors impacts. On the epithelium of the lens of fish, it was found that under the influence of certain pollutants, the mitotic index (MI) in the germinal area can change over a wide range. With the combined effect of toxicants, inhibition of mitosis is also observed. Using biomicroscopy of the eye, it was possible to show that frogs from the urbanized zone of Moscow have 1.5 times more genotypic and modification changes in the lens than their relatives taken from an ecologically clean zone of the Moscow region, Mozhaisky district in the water area of the Ozerninskoye reservoir. For the first time, the sensitivity of the lens of aquatic organisms to chronic effects under experimental and background contamination of the terrestrial and aquatic environment has been shown. Therefore, taking into account the uniformity of the structure of the eye lens of fish and amphibians, as well as in other vertebrates, the lens can be used as a biomarker for assessing chronic and remote environmental contamination. The research results can be applied for a comprehensive assessment of the action of anthropogenic factors.
The Woman’s Images in William Wordsworth’s Poem
Authors: Khairi Miftahul
Published: October 2021

Literature and woman’s images have a strong relationship, particularly in poetry. Some poets use the women as the main object of their works. This study explored the woman’s images in some Wordsworth’s poems; She was a Phantom of Delight, The Solitary Reaper and To a Highland Girl. Those poems could be represented of his works because woman’s figure is so strong and observable in there. New Criticism is the approach which is used in analyzing those poems. Hence, the outcome of this study is the interpretation of woman’s illustration purely in the Wordsworth’s poems. Consequently, this research will utilize the descriptive qualitative research methodology. In data collecting, the research is collected based on the line(s) or stanza(s) which is/are contain the woman’s image figuratively and Imagery. 20 data are found as the result of this study. Therefore, the data is analyzed by using componential analysis to categorize figurative language or imagery. It is apportioned the data according to the theory of intrinsic element of poem. Furthermore, the exploration of the data finding is supported by the interpretation as one of the main points in this scrutiny. Therefore, the all data were substituted into 5 woman’s images categories. They are Mystery, Beauty, Independent, Great and Grace, and Loneliness which are mostly dominated by metaphor and visual imagery, where each of them from figurative language and imagery. This research is constructively developing the study of literature, particularly in poem matter. Moreover, further recommendation for collecting wider explanation is offered in the study.
Lexical Devices in Political Speech (A Study on Gorontalo Mayoral Election 2018)
Authors: Ali Sri Widyarti
Published: October 2021

The use of language in political campaign speech is always interesting to be observed. It mostly contains language features which are intended to convince or persuade people to vote someone into power. Therefore, the language used in political speech has always attracted linguist’ attention to conduct the study of political discourse. This study is aimed to identify and analyze the lexical devices in political campaign speech delivered by the politicians in Gorontalo mayoral election 2018. The data of the lexical cohesive devices are analyzed based on the theory of lexical cohesion proposed by Halliday and Hasan in 1976. Halliday and Hasan have divided the lexical cohesion into two types; reiteration and collocation. Furthermore, the reiteration has four sub-types; repetition, synonym/near synonym, superordinate, and general word. The data identification reveals that the reiteration and the collocation are both found in the speeches. They are successfully used as the tools to deliver the speakers purposes and intentions. Hopefully, this study gives more knowledge and insight to others, especially to the language learners, about how the lexical devices are used in political speeches, and more importantly about how language plays its roles to make people get convinced and persuaded.

A kriminalisztika hipotézisei
Authors: Mészáros Bence
Published: October 2021

The paper intoduces the concept and the several types of hypotheses used in criminalistics, the s.c. investigative theory and its relation to basic questions of criminalistic. The author considers the process of creating investigative theories as a mental event reconstruction in wider sense and raises attention to the most important basic principle during that process, the principle of reality. The study also introduces the applicability of the Occam’s razor philosophical approach, often cited in connection with the creation and evaluation of investigative theories. After introducing the contention of investigative theories, the author analyses the causes and negative consequences of the „sticking to an arbitrarily chosen investigative theory” attitude, as a typical failure in the criminal investigative process.
The Significance of the Black Stool as an Educational Resource in Akan Traditional Patterns of Learning
Authors: Opuni-Frimpong Kwabena
Published: October 2021

The Black Stool has been considered by Western missionaries and missionary
established churches mainly as a sacred object and religious material for rituals
without much attention to its educational significance. The Western missionaries
introduced Christian education and schooling pattern of learning to the Akan
societies. The introduction of Western and Christian education came with Bibles,
Hymn Books, Liturgy books and other educational materials. Even though the Akan
had their own forms of learning, the indigenous educational resources did not attract
the consideration of the missionaries. The missionary legacy of not recognizing
the indigenous educational materials such as the Black Stool has remained with
Christian education in Akan churches and other educational patterns. The study is
an examination of the educational dimensions of the Black Stool and its significance
for moral and leadership formation. Using both primary and secondary sources to
examine the role of the Black Stool in moral education and leadership formation, the
study points out the fact that the Black Stool is capable of providing even education
in Christian history and calls for the need for re-thinking Akan Christian history
to reflect significant intellectual weight embedded in the Black Stool. The study
has established that the Akan Black Stool that over the years has been considered
mainly from its sacred and religious dimensions has educational dimensions that
equally must attract intellectual attention. The study identifies the traditional pattern
of learning as a discipline that must attract intellectual attention. Moreover, there is
a need for a paradigm shift on the perception of the Black Stool. A paradigm shift on
the perception of indigenous educational resources will position the Black Stool as
a relevant educational resource for a traditional pattern of learning. The study calls
for a need for re-thinking of Akan Christian history to retrieve Christian information
and history that have been embedded in indigenous resources like the Black Stool.

INDIAN BANKING INDUSTRY: A NEW EVIDENCE FROM A PROFITABILITY PERSPECTIVE

Published: October 2021

While India is set to become the world’s most populous country by 2050, it is also the home to the world’s largest number of unbanked individuals. This paper aims to investigate the profitability issue with a focus on public banks. Using a new methodology based on comparisons tests and panel analysis that test unobserved heterogeneities between banks. We show that public banks are not low performers, nor can private banks be considered high performers Finally, we show that the proportion of non-performing assets (NPAs) is a real concern and requires urgent attention of government and regulators for Indian banks to serve profitability their home market. Banks that make more profits on non-interest income are not necessarily less profitable than others. Further, outcomes favour the ideas that if public banks are able to clean-up their non-performing assets as well as follow a sound prudential regulation, their profits could strongly grow. Future reforms must consider the public bank’s key role in the growth of the India’s economic outlook, especially when it comes to projects of social importance and national priority. The study is based on 105 banks with cross-sections from 2003–2016; however, India’s government has initiated reforms in the banking segment, which has led to a significant decrease in government stake and the number of banks.
