Prediction of Unloading Failure Strain and Undrained Shear Strength of Saturated Clays by Limit Pressure from Prebored Pressuremeter
Authors: Masoud Zubair , Khan Ammad Hassan
Published: March 2021

Saturated clays mostly fail in lateral unloading by the reduction of undrained shear strength (Su) because of an increase in lateral unloading strain (εu), which is the most predominant factor affecting the soil mass in excavated structures. An attempt is made to extend the work of Houlsby and Withers (1988) on the self-boring pressuremeter (SBP) and Ferreira and Robertson (1994) for the full-displacement pressuremeter (FDP) and SBP, for unloading curves of the prebored pressuremeter (PBP) test for large strain (up to 41.5 %) tests in a specific type of soil (i.e., saturated lean clay, which so far have been rarely analyzed). This article presents a study to examine and explain the magnitude of strains developed in loading and unloading curves of PBP to predict the ratio of compression to unloading strain (εc/εu) and Su from unloading curves, for which open field experimentation is conducted on saturated clay deposits with a plasticity index of 10 to 16 %. The results of εc/εu and Su that were determined from the undrained PBP tests were compared with anisotropically consolidated undrained triaxial compression tests, which showed reasonable agreement. Correlations are proposed for net limit pressure versus εc/εu and Su from PBP, which offer a new approach to quantifying εu and Su by solely performing compression curves. The proposed correlations are validated by performing PBP tests at two separate sites and are further supported by comparison with the pressuremeter curves of previous studies. The variation in experimental versus predicted values for two separate sites (using the proposed correlation) is within ±10 % for a confidence interval of 95 %.
Erythema chronicum migrans like- T cell lymphoma: First description in the medical literature. Successful management with methotrexate and methylprednisolone aceponate!
Authors: Temelkova Ivanka , Tchernev Georgi
Published: March 2021

The group of cutaneous T-cell lymphomas (CTCL) or the so-called Mycosis fungoides (MF) is also referred to as a “great imitator" and in some cases may be misinterpreted as benign inflammatory skin disorders. Difficulties could arise both clinically and histopathologically, especially in the early stages of the disease. For this reason, it is recommended that the diagnosis of MF to follow a three-stage pattern of behavior and be performed on the basis of clinic, histopathology and immunohistochemistry.
SİYEZ VE EKMEKLİK BUĞDAY KEPEĞİNİN EKŞİ HAMUR ÜRETİMİNDE KULLANIM OLANAĞININ DEĞERLENDİRİLMESİ
Authors: ÖRÜ Fatmanur , HENDEK ERTOP Müge
Published: March 2021

Siyez buğdayının kepek ve endosperm tabakaları morfolojik nedenle birbirine sıkı olarak bağlıdır. Una öğütülmesi sırasında, bu fraksiyonlar tam olarak ayrılamadığından, değirmen atık/yan ürünü olarak endospermce zengin ortalama %25 kepek açığa çıkmaktadır. Bu çalışmada siyez ve ekmeklik buğday kepeklerinin ekşi hamur üretiminde kullanım olanakları değerlendirilmiştir, farklı hamur veriminde (HV) spontan fermantasyon ile hazırlanan ekşi hamurlar, pH, biyoyararlanım ve fitik asit (PA) değişimleri açısından karşılaştırılmıştır. Siyez kepeğinin, ince buğday kepeğine göre daha iri taneli olduğu, ekşi maya üretimi için ikinci bir öğütme işlemi gerektiği belirlenmiştir. Siyez kepeğinden en az HV:200, buğday kepeğinden ise en az HV:300 oranıyla ekşi hamur hazırlanabildiği tespit edilmiştir. 72 saatlik fermantasyon sonucu (HV:300) ile hazırlanan siyez kepeği ekşi hamurunun (pH 3.27), ince buğday kepeği ile hazırlanandan (pH 4.89) daha fazla asitlik gelişimi gösterdiği belirlenmiştir. Siyez kepeği (%76.9) biyoyararlanımının, buğday kepeğinden (%73.8) daha yüksek olduğu bulunmuştur. Diyet lif ve mineral madde kaynağı olarak gıdalara ilave edilen kepek fraksiyonunun uygun HV oranında spontan fermantasyonu sonucu, PA degradasyonu ve biyoyararlanım artışıyla, kullanıldığı gıdalarda besinsel kaliteyi yükselteceği düşünülmektedir.
Geometrical consideration for mechanical contact between rolling circle and surface roughness as an improvement to the surface profile
Authors: Shimizu Tsuyoshi , Hramiishi Yasutake , Ishii Takaaki , Rahim Yuzairi Abdul , Ahmad Mohd Fadzil Ali , Watanabe Hiromi
Published: March 2021

This paper describes measurement methods of surface profiles that improve contact-type displacement sensor outputs by focusing on the contact point between the sphere tip of the sensor and the rough surface. We examined the geometry of a surface profile model and compared measurements using various methods with the measurement using a roughness meter. The spherical tip of the contact type displacement sensor touches the measurement surface and detects the displacement. The sphere tip radius of a typical contact-type displacement sensor ranges from 1–3 mm, causing the roughness curve to be “filtered” by the radius of the sphere.  Three methods for estimating the valley portion of the surface profile are evaluated in this study: a) linear approximation of the concave portion of the surface profile, b) function approximation of the concave portion, and c) using the known nose radius of the machining tool. The following sphere tip radii were used to measure actual surface profiles: 0.25 mm, 0.5 mm, 1.0 mm and 1.5 mm. Given the conditions of the experimental model, we found that surface profiles with a roughness that approximates a predictable curve can be measured with a high degree of accuracy.

The subject of this article is an ideological aspect of Pan Tadeusz, directed by Ryszard Ordyński (based on a script by Andrzej Strug and Ferdynand Goetel) as a film adaptation of Adam Mickiewicz’s poem. Picture was realised in 1928 to celebrate the tenth anniversary of regaining of national independence by Poland. Main goal of this article is to reflect in what ways filmmakers of Pan Tadeusz tried to implement a project of Polish national cinema. I also want to present how this film expressed social needs, programme specifications of political power camp and how it explored national values in the cinema.
Ecophilosophy and African traditional ecological knowledge
Authors:   Department of Religious Studies and Philosophy, Delta State University, Abraka, Nigeria, Ikeke Mark Omorovie
Published: March 2021

Ecophilosophy is concerned with the critical study of ecological issues. It critiques the human- earth relationship advocating for friendly treatment of the environment. Philosophy’s interests in the environmental crisis dates back to the late 1960s. Among those who were at the forefront are Holmes Rolston III, Thomas Berry, and Richard Routley. The philosophical movement towards the environment was also inspired by Rachel Carson’s 1962 book, Silent Spring, Garrett Hardin’s The Tragedy of the Commons, Lynn White’s 1967 article, The Historical Roots of the Ecological Crisis, Paul Ehrlich’s Population Bomb, and so forth. It is not that before the 1960s philosophers have not spoken about the environment. The unfortunate thing was that most of the philosophers that had spoken about the environment merely saw the environment or nature from a utilitarian perspective and nature was perceived as an object to be studied, evaluated and conquered without concern for environmental wellbeing. Yet, when the philosophic turn towards the environment began even till today, most of the voices are those of western and Euro-centric philosophers. Indigenous voices and wisdoms from non-western cultures are often ignored. The purpose of this paper is to argue for the place of African traditional ecological knowledge in ecophilosophy and environmental ethics. Through the method of critical analysis, what constitutes African traditional ecological knowledge and its place in global environmental ethics is examined. The paper finds and concludes that global environmental ethics will be incomplete and weakened without the inclusion of African traditional ecological knowledge.
On freedom in the times of Economic Crisis – A Close Reading Of Margaret Atwood's The Heart Goes Last
Authors:   University of Białystok, Feldman-Kołodziejuk Ewelina
Published: March 2021

In her fifth dystopian novel, The Heart Goes Last, Margaret Atwood portrays North America in the not so far future, in the wake of a global economic crisis. Parts of the country are in the state of complete chaos, subjected to a ruthless gang rule. The solution to the system's breakdown comes in the form of the socio-economic experiment that requires from its participants relinquishing their freedom as every other month they will spend in prison. The seemingly preposterous experimental project enables Atwood to explore principal questions about the limits of our freedom in the times of an economic crisis or a neoliberal model of economy. The satirical form the novel takes, especially towards its end, helps the writer to decry people's over-willingness to give away their freedom and civil liberties in exchange for happy, uninterrupted consumption. The following article aims to demonstrate that the notion of freedom and free will permeate The Heart Goes Last, which is, in that respect, a politically and socially engaged satire.
Główne idee nowej prawicy i nowej lewicy
Authors: Jasiński Karol
Published: March 2021

The purpose of the paper is to draw attention to the problem of the division of socio-political life on the right and left and the doctrinal assumptions of the new right and the new left, which are then expressed in social and political programs. The object of these analyzes, however, are not specific political groups or their forms of activity, but only ideological assumptions of social movements. The paper has three parts: 1) it points out that there is no clear criterion for division into right and left, and the use of these terms is polarizing and is conditioned historically, culturally and geographically; 2) the main principles of the new right are presented (economic liberalism, conservatism, minimal state and government, free market, anti-egalitarianism); 3) the ideas of the new left wing were shown (new man, counterculture, criticism, egalitarianism, emancipation, ecology, pacifism).
Nietzsche i Kierkegaard – wspólna wizja nowożytnego podmiotu
Authors:   Uniwersytet w Białymstoku, Krot Michał
Published: March 2021

The task of this work is to make a comparison of subjectivity in the philosophy of Frederic Nietzsche and Soren Kierkegaard in the context of modern metaphysics. It turns out that despite the fact that our XIX century philosophers were trying to go beyond the definition of modern subject by using two separate methods, their thought is marked with similar assumption. It is natural that their projects did not succeed in breaking down the modern metaphysics, but instead it resulted in bringing to an end the possibilities that these metaphysics enabled. This end means a radical defining of a subject as the one who "came out of Matrix" - he is no longer obliged to follow any outside rules. He invents the rules on his own and no one can have an authority over his deeds. Following further consideration it turns out that similarity of two titular philosophers is a solidly grounded thesis and a reference of these conclusions to metaphysics enables us to take up a new look at the shape of modern times. As a result a new philosophy is possible: it is a philosophy which doesn't consider a superman or knight of faith as a culmination of it's thinking, but as a beginning of it.
The anti-Hegelian aspect of Tischner’s theory of truth
Authors:   Uniwersytet Śląski w Katowicach, Jochlik Artur
Published: March 2021

It is stated both by Tischner and his scholars that he follows the footsteps of Hegel. Yet thus far no one – including Tischner himself – was talking about exactly this aspect of Tischner’s thought that is antiHegelian. The best way to do that is to address the issue of truth. Tischner’s theory of truth is antiHegelian because Tischner puts emphasize on the word “feeling”, while at the same time describing his distrust for ontology, which leads him to two things: he thinks about truth first and foremost as a kind of value which is not privileged among other values, and he thinks too little about society. So it is anti-Hegelian because it denies the requirement of Hegel’s science as being the true knowledge of spirit about spirit. In order to understand more from Tischner’s philosophy independently of the issue of Hegel’s philosophy, one should take into consideration Tischner’s theory of evil.

Authors: LOUZADA ROBERTO
Published: March 2021

This article presents the results of a survey carried out in ten sugar and ethanol mills, which were grouped into three categories: closely-held corporations, publicly-held corporations and companies controlled by an international group. The aim was to verify if the model of human resource management and corporate control revel any differentiation in the way the human resource management is conducted. The data were collected through a semi-structured interview, which was answered by the head of the Human Resources Department of the companies, allowing us to describe the practices and to identify the guiding concepts of the adopted model. Data analysis led us to conclude that the corporate control is a component that may differentiate the way human resources are managed in the mills taken as the object of this study.

Estágio supervisionado, práticas de escrita e dispositivos de formação
Authors: Vieira Barbosa Marinalva , Bertucci Barbosa Juliana
Published: March 2021

In this article, the aim is to present a report on how the subjects Supervised Internship I and II, as part of the Portuguese Literature and Language Arts course are organized at the Federal University of Triângulo Mineiro (UFTM). As a theoretical perspective, we combine conceptions derived from the field of education – on how pedagogical internship practices are organized in universities –, a discursive conception of language – based on Foucault (1989) and Bakhtin (1979/2003)–, and a conception of experience as proposed by Larrosa (2004). From this theoretical basis, we assume that writing is a key component to achieving a training that leads future teachers to build their own knowledge about teaching based on the questioning of the possible relations (and existing challenges) between theory and practice. It is, therefore, a report on the construction of teacher education devices – whose central axis is the movement of reflection-action-reflection – which allows Literature and Language Arts students to write in such a way that is the result of knowledge about the teaching of the Portuguese language.
Da escuta ao registro: estilos de discurso reportado em relatórios de estágio
Authors: Massao Fairchild Thomas
Published: March 2021

We analyze cases of reported speech in internship reports written by Brazilian Language Arts students with the aim to associate the style employed by them when citing a third party’s speech with the positions they sustain in their texts. We believe that the way in which students report this speech hints at how they “listen” to what goes on in class and how they revisit and organize their own experience by writing about it. That kind of analysis can cast light upon the forms of perception of the school available in academic culture and, all the same, the individual choices made by students when faced with that culture. To analyze our data, we draw from M. Bakhtin (2004, 2015), especially the notions of “linear” and “pictoric” style, the counterpoint between “expression analysis” and “content analysis” and the concept of “bivocal discourse”. We were able to find passages that represent various styles of reported speech but we could hardly find any signs of a particular style being employed to support the construction of a cogent and persistent position. It would seem that reporting teachers’ and students’ speech is influenced by questions that range from phrasing problems to how the author of the report reacts to the speech that is being reported.
Las lagunas discursivas en las producciones de un diario de campo y de un portafolio: ¿Pérdida de sentido de lo que se enseña?
Authors: Dos Santos Ariadne Catarine , Medina Mejía Lexy
Published: March 2021

In recent years, many studies about language (BARZOTTO & EUFRASIO (2009); FAIRCHILD (2013, 2014); REZENDE (2010)] have shown that a teaching practicum has to be thought as a reflexive pedagogical event, where students become researchers of their own teaching experience; such activity allows them the analysis and assess of their own experience and also the validation of knowledge, methodologies and teaching strategies. It is during this teaching practicum that teaching journals, as a database of the close observation of the practicum-student, should become an important reflexive instrument of classroom activity. However, the written products from Spanish teaching practicum-students in a public university in Central America show that, on many occasions, students do not know how to use such resource, since journals show little connection between the discourse of the official documents and the student’s written work. Such problem gives the idea that the meaning of concepts taught may not be found in the final work a student submits. For the purpose of this research, we selected a journal and a portfolio from a student in a Spanish teaching program. These two sources were considered successful final productions. Moreover, they allowed the researchers to start a discussion about how this student articulated and analyzed his own data. Coherence of the produced discourse and the specific knowledge from the program— in this case Spanish teaching— the meaning ( or not) and the usefulness such productions have for the practicum-student and for the practicum-supervisor, and the role of the teacher as the one in charge of the follow-up and monitoring of the practicum are discussed.
The derivational family of the noun SAULĖ
Authors: Vaskelienė Jolanta , Girdvilytė Greta
Published: March 2021

The word saulė (‘the sun’) and the denotation indicated by it has a lot of meanings in the Lithuanian culture: the mythologists, philosophers, art critics, and literature critics have written about this phenomenon. The article analyses the derivational family of the noun saulė. Having analysed the derivatives with the root word saul (or one of the root words) found in various sources and the relations between them, the following conclusions have been drawn.The derivational family, the centre of which is the noun saulė, consists of 287 derivatives: mostly nouns (78 per cent of all derivatives), adjectives (15 per cent), verbs (4 per cent) and adverbs (3 per cent). First degree derivatives are dominant, i.e. such derivatives whose underlying word (or one of them) is the noun saulė: cf. first degree derivatives make 74 per cent of all derivatives, and 26 per cent of all derivatives of further derivation stages.The nouns are formed by using all derivational types; however, the compound nouns prevail: they make 69 per cent of all noun derivatives. 61 per cent of compounds are with the second verbal component. The components of 34 per cent of compounds are linked with the vowel -ė-. Some compounds have direct meanings (they denote purpose and place), and many more compounds have figurative meanings (metaphorical and metonymic). The noun saulė almost always (99 per cent) is the first component of the first degree compounds.There are a few neologisms – the derivatives or the derivatives that have acquired a new meaning – in the derivational family of the noun saulė. New realia are named as neologisms or they are variants and synonyms of derivatives incorporated in dictionaries.The research revealed that, in the Lithuanian language, the same entities (mostly plants, phenomena) are named in terms of variation: 40 rows of derivational variants (DV) and 33 rows of derivational synonyms (DS) have been formed and discussed. The plant saulėgrąža (‘a sunflower’) and the time when the sun sets down saulėlydis (‘the sunset’) have a particularly high number of conjugate names: in these rows of DV and DS, there are 33 and 29 derivatives, respectively. Although in many cases DV and DS are the words of a close (or even identical) semantical meaning, their usage and frequency differ: usually only one member of the DV and the DS row is common to the contemporary Lithuanian language, it is often used, while other derivatives often belong to the passive lexis and are known to a small part of the Lithuanian language users, or are recorded in written sources. In rare cases, conjugate derivatives are related in terms of antonyms.
Metaphorical somatonyms of northern Samogitians: artefactual motivational model
Authors: Lubienė Jūratė , Pakalniškienė Dalia
Published: March 2021

The article presents the analysis of the onomasiological structure of the metaphorical somatonyms of Northern Samogitians, focusing on the indicators of the source of metaphors. Based on the explicit semantics of the source (lexical motivators), the metaphorical somatonyms of Northern Samogitians belong to several motivational models, the most productive of which is the artefactual motivational model. The basis of the artefactual metaphor is the associative similarity of the object (artefact) and the body part according to various parameters – shape, size, features of structure and materiality, actions, especially repetitive movements.
Some spelling and language features of publicistic works by Povilas Višinskis
Authors: Maskuliūnas Bronius
Published: March 2021

Povilas Višinskis was a significant figure of the Lithuanian culture, society, and politics at the end of the 19th c. and the beginning of the 20th c., an active advocate of the Lithuanian national movement, a member of the national revival organisation Varpas, and a supporter of the movement to regain the banned Latin characters for the Lithuanian language. His creative legacy includes various publicistic works, found in the press or published as separate booklets; that has yet received little attention. The paper analyses some characteristic spelling and language features of publicistic works by Višinskis.Concerning the spelling, a special focus should be on its promiscuity and randomness. The principles of spelling are mixed up, different word forms are used side by side in the same text, and often it is difficult to explain the reasons and consistency of a particular spelling. With this in mind, it is rather difficult to tell which language and spelling is authentic, and which is edited, proofread or corrected by editors. At the same time, it should be pointed out that such variation in spelling is common to Lithuanian writings of that time, reflecting a phase of the developmental process of the standard language at that time.What concerns the language of Višinskis’ publicistic works, it is characterised by the use of some Samogitian features, rather frequent retention of archaic morphological forms (dual number of nouns and verbs, supinum, athematic verbs, archaic pronominal forms) and cases of stem mixing of nouns. His vocabulary is full of dialecticisms, barbarisms, and semantic archaisms. His syntax contains a lot of non-Lithuanian, foreign constructions, especially those with prepositions.In conclusion, one could say that gradually Višinskis’ language and spelling became more homogeneous. In his latest publicistic works, this language and spelling uniformity becomes clear, while particular forms and constructions are used more consistently.

Using laterally ordered arrays of noble metal nanocavities as SERS substrates has been examined theoretically and experimentally. Simulation of the distribution of the electric field at the surface of nanostructures (nanocavities) has been carried out. The simulation results showed that cavities can be formed not only in a metal layer but in semiconductor or dielectric layers and then covered with a layer of a plasmon-supporting metal (silver or gold) 20…100-nm thick. In our work, chalcogenide glass has been used as a relief-forming layer. This paper presents the results of development and optimization of processes providing formation of SERS substrates as two-dimensional arrays of noble metal nanocavities by using interference photolithography based on a two-layer chalcogenide photoresist. Prototypes of SERS substrates were made as substrates with different spatial frequencies (from 1200 to 800 mm -1 ) and depths of nanocavities (from 250 up to 500 nm). It was shown that the use of such nanocavities with the sizes larger than 500 nm enables to efficiently analyze the structure of macromolecules by using surface- enhanced Raman light scattering spectroscopy, since these macromolecules completely overlap with the regions of enhanced electric field inside the nanocavities. Technology of interference lithography based on two-layer chalcogenide photoresists makes it possible to form effective SERS substrates in the form of laterally ordered arrays of nanocavities with specified morphological characteristics (spatial frequency, nanocavity sizes, composition and thickness of a conformal metal coating) for detecting high-molecular compounds.

Both static and dynamic characteristics of light reflected from a specially designed multilayer metal-dielectric structure with Kerr nonlinearity have been studied in this work. Various regimes of nonlinear reflection from the structure have been demonstrated, including bistable switching between low and high reflection states, which occurs at low intensity of the incident light due to a significant enhancement in the optical field in the nonlinear layer under conditions of total internal reflection. This nonlinear structure has been proposed to use as an optically controlled intracavity laser modulator.
A review of high ideality factor in gallium nitride-based light-emitting diode

Theory concerning the high ideality factor of gallium nitride (GaN) based light- emitting diode (LED) has been reviewed. The presence of a high ideality factor indicates a large forward voltage that results in efficiency reduction. The paper suggests that tunneling is the main reason defining the exponential behaviour of current-voltage measurements, which leads to a high ideality factor. However, there is also a paper that suggests that the design of current geometry in the LED chip defines the value of ideality factor. An effective current spreading geometry in the LED chip will minimize the ideality factor and make it fall between the ideal range of 1 to 2. Besides, how the ideality factor is calculated will also play a major role in defining its value. By calculating the ideality factor based solely on the radiative recombination current formula, the value of ideality factor can result in an ideal ideality factor of 1.08.

The author of the article, based on the study of the works of domestic and foreign scientists, generalized the study of the conceptual field of immigration. Indeed, over the past decades, Ukraine has become one of the largest suppliers of emigrants to Europe and the United States. At the same time, now the state policy of Ukraine is aimed at the development of immigration processes, which motivated the study of this phenomenon in the domestic science "Public Administration and Administration".The author also investigated the theoretical determination of the concept of "immigration", its characteristics according to various features: dynamics, scale and structure of immigration processes (the number of immigrants, their gender and age composition), factors of stimulating immigration, the characteristic features of the formation of the modern labor market and the directions of development of modern immigration processes.The author argues that many scientific works are devoted to the study of a wide range of issues of theoretical and applied aspects of labor migration. Recently, the issues of a comprehensive analysis of the current migration situation in Ukraine, assessment of the impact of migration on demographic and socio-economic development, forecasting migration of the population, ethnic composition of the population and factors of its dynamics have been studied. In connection with the annexation of the Autonomous Republic of Crimea, the military events in the East of Ukraine, which were caused by the aggressor country Russia (since 2014), the topic of not only internal migration of the Ukrainian population, but also the return of Donetsk residents from the CIS countries to Ukraine, has become relevant.The massive incidence of infectious coronavirus disease in humanity in 2020 posed new challenges to the government of Ukraine related to the immigration of our compatriots from foreign countries, which are introducing a strict quarantine regime amid the COVID-19 pandemic. According to the author, the study of the conceptual field and essential characteristics in the context of modernity is relevant, which determined the choice of the topic of the article.

It is confirmed that the development of health and physical activity of the population of megacities is also influenced by related city programs (in the field of culture, education, medicine, patriotic education, tourism development, etc.), which can act as additional mechanisms in implementing public policy in public health. It is established that programs for the development of physical culture and sports are financed mainly from local budgets. It is determined that the weak point of the program-targeted support of public administration activities in the socio-humanitarian sphere is the direction of monitoring and evaluation of programs, in particular in the field of development of physical culture, physical activity and sports. According to the results of the study, it is proposed to introduce into the existing programs such priority groups of indicators in the direction of health and physical activity of the population as: indicators of financial and economic support; indicators of development of infrastructure of improving motor activity; indicator of statistical accounting. This will help increase the effectiveness of local programs in strengthening the population health of the community through the development of the non-medical sector of the urban economy of Ukrainian cities.
