The aim of this study was to prepare microcapsules and transfer them to denim and non-denim trousers using different application methods. For this purpose, shea butter as active agent was encapsulated in an ethyl cellulose shell using the spray dryer method, and capsule optimization was studied. A morphological assessment showed that the capsules had a smooth surface and were spherical in shape. The homogenous size distribution of the capsules was supported by laser diffraction analysis. The capsules showed a narrow size distribution, and the mean particle size of optimum formulations of shea butter was 390 nm. Denim fabrics were treated with shea butter capsules using the methods of exhaustion and spraying in order to compare these application methods. The presence of capsules on the fabrics was tested after five wash cycles. The comparison of application methods found similar preferred characteristics for both the exhaustion and spraying methods. However, the spraying method was found to be more sustainable, because it requires working with low liquor ratios in less water, with lower chemical consumption and less waste than the exhaustion method, which requires working with a high liquor ratio. This study showed that the spraying method can be used as an alternative to other application methods in the market for reducing energy consumption, and shea butter capsules can provide moistening properties to the fabrics.

Zeitgenössisches Theater überschreitet zunehmend  den institutionellen Rahmen des Stadttheaters und verändert zugleich das Verhältnis von Dramentext und Inszenierung, Produktion und Prozess, Interpretation  und Lektüre. Die Autorenregisseur_innen  René Pollesch, Christoph Schlingensief, Sabine Harbeke und SIGNA zeigen je eigene Modelle, wie der Dramentext kurz vor, während oder sogar erst nach der Aufführung Gestalt annehmen kann, wie der Produktionsprozess den Theatertext unnachspielbar macht und wie die Rezeption der Zuschauenden von der semiotisch geschulten Interpretation eines aufgeführten Dramas zur teilnehmenden Lektüre eines Theaterereignisses im öffentlichen und subjektiven Raum wird.

Global Transfer. Überlegungen zu Geschichte und Formen internationalisierten Theaters
Authors: Gronau Barbara
Published: March 2021

Das zeitgenössische Theater zeichnet sich durch eine große Heterogenität der Ästhetiken, Traditionen und Zielrichtungen aus. Mit der Perspektive auf eine internationale Ästhetik stellt sich die Frage nach Gemeinsamkeiten und Differenzen in den Produktions- und Rezeptionsweisen von Theater heute. Gibt es so etwas wie eine globale Theaterszene überhaupt? Was wären ihre Merkmale? Wo und wie treffen internationale Theatermachende aufeinander? Wann internationalisiert sich Theater und welche produktiven Missverständnisse markieren diesen Weg? Der Beitrag wirft Schlaglichter auf die historische Entwicklung von internationalen Theaterkulturen und fragt nach Prinzipien des globalen Produzierens und Rezipierens heute.
Ein Ding unter vielen. Robbert&Frank/Frank&Robberts Theaterinstallation TO BREAK – The Window of Opportunity
Authors: Burger Franziska
Published: March 2021

Eine Bühne, so karg wie die Prärie im Mittleren Westen der USA. Lediglich ein Hintergrundprospekt ist zu sehen, auf dem ebendiese Landschaft aufgemalt ist. Doch diese suggerierte Einöde trügt, denn auf den zweiten Blick sind neben Cowboys und Indianern auch eine Sphinx, Skulpturen von der Osterinsel und gar fliegende Wale zu entdecken. Das Bühnenbild von TO BREAK – The Window of Opportunity (2014) deutet es bereits an: In dieser Performance ist nichts so, wie es zunächst scheint.

Published: March 2021

Background: Conditioning activities such as resistance training can cause excitation of central nervous system resulting in Post-activation Potentiation phenomenon. Plyometric exercise also has an important role to develop Post-activation Potentiation following a resistance stimulus. So the purpose the study was to investigate the immediate effects of weighted plyometric exercise on sprint, agility and jump performance. Materials and methods: Twenty male university football players (age=21.3±1.5 years, body mass=63.3±9.5 kg, height=169.8±6.4 m) participated in this Single group pre-test post-test study. Agility Time (AT), Sprint Time (ST) and Counter-Movement Jump (CMJ) height were measured prior to and 1st and 5th minutes following plyometric exercise. Results: A repeated measures ANOVA employed at baseline (T0), 1 minute (T1), and 5 minutes (T5) post intervention showed significant effect for all the three outcome measures (p<0.001). Post-hoc Bonferroni pairwise comparison showed a significant decrease in both AT and ST from baseline to assessments at both T1 (p<0.001) and T5 (p<0.001), whereas there was a significant increase in the CMJ height. However, no statistical difference was found between T1 and T5 (p=0.058) in ST, but AT was significantly lower at T5 than at T1 (p=0.008), and CMJ height showed significant increase from T1 to T5 (p=0.001). Conclusion: Our results suggest that weighted plyometric exercises have an acute response on sprint, agility and counter movement jump (CMJ Height) following Post-Activation Potentiation (PAP) effect developed after plyometric exercises.

Materials: Eighteen male army soldiers were randomly assigned in a double-blind fashion to either a CrHCl (n=9) or placebo (Pl) (n=9) groups. CrHCl group costumed 3g of creatine per day, whereas Pl group was given dextrose. Before and after supplementation period, the subjects performed a battery of performance tests including one repletion maximum (1RM) of bench press and back squat, vertical jump (VJ) and Wingate anaerobic test. In addition, blood samples were obtained to determine changes in testosterone and cortisol concentrations per and post supplementation. Results: There were significant increases in VJ, peak and mean power, and 1RM back squat test following the 2 weeks of CrHCl supplementation (p < 0.05) without any significant change for the Pl group. In addition significant changes were observed in testosterone and cortisol concentrations from before to after supplementation in CrHCl group (p < 0.05) and compared with Pl group (p=0.001). Conclusions: In conclusion, the present study indicates that CrHCl supplementation can improve VJ, power performance, 1RM back squat and hormonal changes in army soldiers.
Theoretical Investigation Of Coverage Effects Of CO Adsorption On Cu(100) Surface
Authors: ÖZBEK M. Oluş
Published: March 2021

This work investigates the CO adsorption on the metallic Cu(100) surface using periodic DFT computations. CO adsorption was studied at varying coverages from 1/16 ML to 1/1 ML for a combination of adsorption positions (4-fold, bridge and top). The results showed that adsorption energies are coverage dependent, however, not enough to identify the adsorption site and coverage. However, C-O stretching frequencies are almost unique for studied coverage and adsorption positions. CO adsorption energy changes between -250 kJ/mol to +21 kJ/mol; similarly, the vibrations’ range in the 1702 cm-1 to 2110 cm-1 interval, within the studied coverage and adsorption positions. Nevertheless, under the saturation coverage (θCO ≈ 0.55ML) the preferable adsorption site is the on-top position identified with a C-O stretching frequency around ~2100 cm-1 and with ~117 kJ/mol adsorption energy.

Optimierte Reglereinstellung bei Kälteanlagen
Authors: Haußer Sebastian
Published: March 2021

Kälteanlagen können aus regelungstechnischer Sicht als stark nichtlinear mit starken Prozesskopplungen charakterisiert werden. In der Praxis werden in der Regel lediglich einfache klassische Regler (Zweipunktregler, P/PI-Regler) mit fest vorgegebenen Reglerparametern eingesetzt. Für eine konkrete Kälteanlage werden mit Hilfe des praxisorientierten Reglerentwurfsverfahrens nach Chien Hrones und Reswick die Reglerparmameter eines PI-Reglers, welcher einen Ventilator ansteuert, ermittelt. Mit Hilfe eines dynamischen Simulationsmodells werden Streckenkenngrößen und darauf aufbauend die Reglerparameter berechnet. In Simulationsstudien werden die Auswirkungen von unterschiedlichen Reglerparameterpaaren zum einen auf die Energieeffizienz und zum andern auf die Regelgüte betrachtet.

Calculation of non-stationary heat exchange in multi-layer media by means of the theory of Markov chains
Authors: Ogurtsov A.V. , Krupnov E.I. , Kormashova E.R. , Mizonov V.E.
Published: March 2021

Calculation of non-stationary heat exchange in multi-layer dissimilar media is the problem, which is often found in many industries including high temperature metallurgic technologies of production and treatment of metals, alloys and their products. The similar problems arise during the design of buildings and structures. The models used for calculation are mainly based on approximate solutions of classical heat conduction equations. The drawback of such models is a complex computational procedure, associated with the need to solve a large number of equations and to define a large number of identification parameters. At present, the calculation of one mode of heat transfer between the sections of a composite structure requires 6–8 hours of operation of a computer of average power. In this regard, the development of discrete models that require less computer time is of current importance. The proposed model of the process is based on the theory of Markov chains. A multi-layer medium is presented as a chain of small but finite cells. Each of them contains a certain amount of heat that can be transferred to the neighboring cells. The part of the transferred heat is directly proportional to the heat conduction coefficient and in inverse proportion to the material heat capacity, material density and the cell length. The matrix model to describe heat transfer between cell in a multi-layer media based on the theory of Markov chains is developed. Construction of the matrix of transition probabilities is described, evolution of the state vectors i.e. distribution of heat and temperature is carried out, and non-uniformity of the heater temperature is taken into account. Comparison of calculated and experimental data has showed the adequate description of the real process using the model. Analysis of identification parameters has given a satisfactory result.
Multi Agent System Based Risk Allocation Model for Public-Private-Partnership Type Projects (RAMP3)
Authors: ALADAĞ Hande , IŞIK Zeynep
Published: March 2021

The performance of the Public Private Partnership (PPP) projects depends on the efficiency of the risk allocation strategies between the public and private parties. Therefore, a multi agent system-based Risk Allocation Model for PPP projects (RAMP3) was developed to determine the proper risk allocation decisions between the public and private parties within the study. The methodology of RAMP3 involves i) identification of risks by agents, ii) assessment of each risk’s importance and impact, iii) communication of agents to negotiate on risk allocation decision and iv) determination of strategies and utility functions to be used in negotiation process. Focus of the study is presenting the steps of negotiation process of agents using economic theory and Zeuthen bargaining strategy. RAMP3 was validated on two real PPP projects and results show that the higher risk value of an agent gets, agent’s utility due to counter agent in that concession round lowers. Preliminary findings also show that risk is allocated to the party that has a higher risk acceptability in negotiation process. The RAMP3 will enable project parties to determine the appropriate risk allocation strategies by considering the effects of emerging risks in terms of time delay, cost overrun and conflict and provide contract success. The model can also be used as a decision support system by public partner for performing an efficient and accurate risk allocation.
Experimental Investigation on Hydraulic Efficiency of Vertical Drop Equipped with Vertical Screens
Authors: DANESHFARAZ Rasoul , SADEGHFAM Sina , HASANNİYA Vadoud , ABRAHAM John , NOROUZİ Reza
Published: March 2021

In the present study, vertical screens were utilized at downstream of vertical drops to increase the energy dissipation of subcritical flow. The experiments were carried out using screens with two different porosity ratios (40% and 50%) and three different distances from the drop brink (30, 60 and 90 cm). The results reveal that drops equipped with screens increase the relative downstream depth, the relative pool depth, and the relative energy dissipation compared with a plain vertical drop. By increasing porosity ratios and the screen distance from the drop brink, the relative downstream depth and relative energy dissipation increase, whereas the relative pool depth decreases. Also, by increasing the relative critical depth, the relative energy dissipation of the vertical drop decreases, whereas the energy dissipation related to the screens increases. However, increasing the relative critical depth initially increases and then decreases the performance of the hydraulic jump in terms of total energy dissipation.

Published: March 2021

The results of studies of cutting fluids on three types of solvents are presented: distilled water, tap water and treated surface effluents of the factory. It has been proven that replacing tap water with treated surface wastewater when preparing soda-nitrite solutions does not affect the operational and functional properties of the coolant. The possibility of using the treated surface runoff of a bearing factory for the preparation of coagulant solutions for the purpose of using it in the purification of emulsion wastewater has been confirmed. Shown are the directions of recycling waste treatment of the surface runoff of the factory, in particular in the construction industry in the production of asphalt concrete.

Authors: Kazakova N.A. , Kogdenko V.G.
Published: March 2021

A critical analysis of the existing approaches to monitoring the main parameters of the environmental safety of industrial production is presented, a number of shortcomings are revealed associated with the limited compliance methods for assessing the compliance of environmental indicators with current standards, or the degree of information transparency of companies; the lack of consideration of the impact of dividend and investment policies of companies on the environmental safety of industrial production; lack of comparability of environmental performance in public reports. The scientific novelty of the proposed monitoring lies in the use of a systematic approach to the formation of the main parameters of environmental safety and the expansion of monitoring directions by including trends in the relationship between economic and environmental indicators calculated from the data of public reports of companies. The study was carried out on the example of the metallurgical industry in Russia, which made it possible to assess the representativeness of environmental reports and trends in the environmental safety of the industry.
Simulating air distribution system for civil aircraft
Authors: Gusarkin S.N. , Skidanov S.N.
Published: March 2021

The paper considers an air distribution system for a pressurized cabin in a civil aircraft. We propose a method for simulating this system that involves developing a one-dimensional model based on hydraulic computation results for the three-dimensional geometry of the distribution system structure. This approach makes it possible to recompute air distribution in large branching systems relatively quickly and with sufficient accuracy when making changes to their design. The advantages of this method include lower computing costs and lower labour intensity compared to using a modern CFD software package to simulate a full three-dimensional flow in the distribution system structure. The paper describes the operation of the air distribution system prototype and presents the schematic diagram and the functional flow block diagram of the system. We show how to use three-dimensional simulation to determine the discharge characteristics of system pipelines. We present the numerical model constructed for the system and display the capabilities of this model in static and dynamic simulation modes. We analysed the simulation results and confirmed the possibility of using the method proposed for engineering computations. We validated the numerical model using experimental investigation results obtained by means of an empirical test bench simulating the air distribution system prototype.

Authors: Melnikov A.Yu.
Published: March 2021

The paper overviews works on methods for solving problems of aerospace aircraft control and aims to solve the remaining problems. The purpose of the study was to obtain reference optimal control and its approximation in the guidance functions. When stating the problem, we took into account all essential physical factors; we selected the solution techniques and computational coordinate system, developed a mathematical model, methods and automated procedures for end-to-end optimization relying on the maximum principle, the formation and optimization of guidance functions. In addition to the well-known methods for solving boundary value problems, methods of analytical calculation of the initial approximation and the search for the convergence region were developed. The results of numerical studies contain nominal and perturbed optimal trajectories in which an aerospace aircraft is boosted by an accelerator, performs global spatial maneuvers, and enters orbit. Having analyzed extremals, compared and evaluated the effectiveness of the guidance functions, we drew certain conclusions taking into account the perturbations.
Adapt or die in the time of a pandemic: Towards a grounded theory of strategic adjustments by an early childhood development training organisation
Authors: Kruger Erika
Published: March 2021

The COVID-19 pandemic has led all role players in the Early Childhood Care and Education (ECCE) sector in South Africa, including the particular non-profit organisation (NPO) under investigation, into unchartered territory. The organisation, which is involved in training and mentoring community-based Early Childhood Development centres in marginalised settings, was forced to pivot its service as the country went into lockdown in March 2020. The purpose of this grounded theory study is to discover how employees and associates of this organisation view the adjustments that had to be made during and after lockdown to support principals, staff members and through that the children, their parents and the community during COVID-19 lockdown. Findings indicated that the team was able to rely on existing strengths that intersected on several points to tackle the challenges, namely strong internal and external relationships, sound administrative and business systems and a flexible, risk-taking and social entrepreneurial ethos. This kaleidoscopic combinations of relational, attitudinal and organisational factors, permitted swift adjusting, a strength that may support the sustainability of this NPO and others of its kind, not only during the pandemic but also in its aftermath and with the socio-economic upheaval it has caused particularly among indigent communities.
The COVID-19 pandemic: Streamlining or capsizing the global higher education revolution
Authors: Wolhuter Charste , Jacobs Lynette
Published: March 2021

The aim of this article is to interpret the outbreak of the COVID-19 pandemic within the frame of the global higher education revolution. One of the striking elements of the contemporary world since 1990 is a global higher education revolution. While the most prominent feature of this revolution is massification, it is a multifaceted revolution, involving all aspects of higher education, including the curriculum, methods of teaching and learning, the academic profession, funding, relations between higher education and government and management. This article first outlines the societal drivers of this revolution, being demographic shifts, increasing affluence, the rise of knowledge economies, the neo-liberal economic revolution, the information and communication technology (ICT) revolution, the rise of multicultural societies, democratisation, individualisation and the rise of the creed of human rights and next key features of the revolution will be surveyed. The revolution is then critically evaluated by interrogating and using as yardstick the unique, indispensable mission of higher education in society. The changes that the pandemic are forcing in the higher education sector is then assessed against the potential of the disruption brought by the COVID-19 pandemic to redress or strengthen the discontents of this global higher education revolution.

Published: March 2021

Since the outbreak of the coronavirus pandemic, socio-economic inequalities have become exacerbated and COVID-19 related hate crimes have increased. This paper explores how citizenship education might be reimagined in response to this context, with the vision of rebuilding a more equitable and compassionate society. By using a collective autobiographical writing approach, this study documented six different autobiographical reflexivities of citizenship education scholars who were from different parts of the world: China, South Korea, the Philippines, the United States, Nepal and the United Kingdom. It also observed the way the pandemic played out in the location where they were situated during the research as well as how it played out in their countries of origin, and further, how it affected the civic development in each context. The scholars' range of autobiographical expressions resulted in insights for developing a type of citizenship education, namely, education for active and compassionate citizenship.
Progress of an African student during COVID-19 and beyond in higher education: Re-colonisation of decolonisation?
Authors: Kgari-Masondo Maserole Christina , Chimbunde Pfuurai
Published: March 2021

Following the closure of educational institutions, after the outbreak of COVID-19 in December 2019, even though grossly unprepared, universities sent their students home and adopted the online teaching approach to continue with the education of their students. However, little was done to assist most African students who were living in the rural context and trying to shake off the constraints of colonisation. Using the decolonisation lens, this qualitative case study used the lecturers’ personal experiences and observations from the South African and Zimbabwean higher education context to report on the educational progress of the African student during COVID-19. Discussions of the two lecturers who communicated via WhatsApp, telephone and email were thematically analysed to generate data. Findings suggest that while the online teaching was regarded as the only way forward in the middle of the COVID-19 pandemic, it had remnants of colonialism that hampered the progress of the African student; thereby derailing the decolonisation project. The study suggests the employment of Umuntu Akalahlwa pedagogy as it safeguards humanisation of all students to avert the re-colonisation of the decolonised. The rationale for this article is thus to contribute towards the need for Umuntu Akalahlwa pedagogy in higher education given the background of COVID-19 and the socio-economic status of the African student.

Published: March 2021

Cyberchondria is the name given to individuals who research their existing or imaginary diseases online. We developed a scale for measuring individuals’ cyberchondria tendencies. The 36-item test form produced was applied to 1,200 participants (694 male and 506 female) residing in different provinces, with health problems in the previous month and accessible via e-mail. The data obtained were then subjected to analysis. A structure consisting of 30 items and two dimensions, ‘Reflection’ and ‘Information Seeking’ was obtained with exploratory factor analysis. The relation between the entire scale and the subscales was investigated and the factors were determined to be positively and significantly correlated. The goodness of fit indices of the model was at acceptable levels. The validated scale can be used to determine whether or not both patients and Internet users in general regard the Internet as a basic source of information when health problems occur.

Published: March 2021

In the Arab world, there is a lack of research investigating the use of virtual games to support learning English as a foreign language (EFL). The aim of this study was to examine EFL learners' attitudes towards the integration of the Second Life virtual game as a collaborative instructional tool. A descriptive inquiry method was followed, and data gathered using a questionnaire that had been tested for validity and reliability. Forty-one undergraduates, enrolled in two computer-assisted language learning classes, at a school of education represent the study sample. Findings indicated that the majority were in favor of using virtual worlds as collaborative learning contexts. Recommendations include that: 1) EFL teachers be trained to utilize virtual games; 2) EFL learners be encouraged to utilize virtual portals as collaborative learning opportunities to engage with target foreign language speakers around the world, and 3) EFL instructors create learning tasks requiring learners to interact with other language speakers in virtual games to ensure rich language exposition. Moreover, it is recommended that further studies consider a qualitative design that makes use of in-depth observations and interviews to explore learnersâ€™ attitudes about the integration of this technology in an EFL context.

MAURICE: THROUGH THE LENSES OF LACANIAN “MIRROR, MIRROR, ON THE WALL…”
Authors: TÜFEKCİ CAN Dilek
Published: March 2021

Maurice, a bildungsroman by E. M. Forster, revolves around the theme of homosexuality. By presenting homosexual characters, who are on a futile quest for their actual identity, Forster attempts to be the voice of the unspeakables in the Edwardian period in England, where all acts of homosexuality were considered illegal. In this paper, the identity of the characters is analysed through the lenses of Lacanian psychoanalytic theory by focusing on the concept of mirror. This paper attempts to reveal to what extent cultural codes and societal norms of the Edwardian period are functional in forming the identity of the characters. Besides, this study uncovers that Forster wisely uses Lacanian concepts such as imaginary order, symbolic order and real order in creating his characters. It is concluded that the mirror, which reflects the actual self of the characters, just like dreams and music, plays a significant role in (re)forming the identities from compulsory heterosexuality to voluntary homosexuality.
JOHN FISKE AND POPULAR CULTURE: A CRITICAL READING OF MARGARET TYLER’S “EPISTLE TO THE READER”
Authors: AYDOĞDU ÇELİK Merve
Published: March 2021

This paper examines how Margaret Tyler overcomes literary inferiority in the “Epistle to the Reader” that precedes her translation The Mirrour of Princely Deeds and Knighthood. Tyler, as a woman and an author, is in a secondary position in the patriarchal Elizabethan society and print culture. Notwithstanding her disadvantaged status, she circumvents it through various tactics, and she defends both her act and women’s right to write. Tyler does not overtly challenge the assumptions prevalent in print culture but manipulates them to her own end. The fact that she employs several strategies to earn a place in the system renders it possible to evaluate the preface within the framework of John Fiske’s popular culture theory. As is evident from the “Epistle,” Tyler resists the dominant culture, and she produces her oppositional stance out of the resources of the dominant. Thus, Tyler’s preface functions as an element of popular culture.
THE LABYRINTHINE SPACE AS REFLECTED IN PHILIP RIDLEY’S PLAY MERCURY FUR
Authors: GOLBAN Tatiana
Published: March 2021

This study focuses on Philip Ridley’s Mercury Fur (2005), a play which explores various meanings related to a physical labyrinth, memory as a maze, mirror/glass as a labyrinth, etc. The present study aims to disclose primarily the significance of the physical labyrinth, presented in Ridley’s play mostly as a radical space, a reminiscent of Foucault’s “heterotopia”, in which the characters cannot be domiciled, but are rather haunted, their inevitable entrapment creating a perpetual existential feeling of anxiety. This study also attempts to discuss the issue of memory as a maze, revealing the playwright’s concern for the precariousness of memory while the national or individual identities are pursued. In a space in which everyone and everything is manipulated, Ridley’s characters, in their struggle for survival, are forced to re-negotiate all the known thresholds of cruelty and transgression in order to discover the path leading them to humanness and morality.
LA DIMENSION RECRÉATIVE DES « TENDANCES DÉFORMANTES » DANS LA TRADUCTION DE J’IRAI CRACHER SUR VOS TOMBES
Authors: DİNDAR Serhan
Published: March 2021

Antoine Berman, théoricien important dans la traductologie, a favorisé la traduction cibliste pour les textes littéraires. Il a évoqué certaines tendances du sujet traduisant nommées « les tendances déformantes ». Ces tendances se montrent plutôt dans la traduction interlinguale des textes littéraires. Le sujet traduisant réalise une opération de destruction formelle, lingual et structural mais il doit protéger le sens, le message et le vouloir dire du texte original. Pour donner (presque) le même sens dans le texte d’arrivée, le sujet traduisant fait en même temps une recréation du sens. D’une part, il pratique les tendances déformantes au niveau du signifiant, d’autre part il recrée le sens du texte source au niveau du signifié. L’objectif de ce travail est de constater la dimension recréative des certaines tendances déformantes et d’analyser ces tendances déformantes et recréatives sur la traduction en turc du roman J’irai cracher sur vos tombes de Boris Vian.
THE CAR AS A THING: LATİFE TEKİN’S SWORDS OF ICE AND JOSÉ SARAMAGO’S “EMBARGO”
Authors: KAYA Hilal
Published: March 2021

From a transnational and trans-historical perspective, this paper lays stress upon the car as a technological material and its fictional representations in Latife Tekin’s Swords of Ice (1989) and José Saramago’s “Embargo” (1978). Readers from different cultures have been attracted to car narratives because they are “thing-driven” – based on cars – as a representative of the matter which can speak for themselves, as it were. This study claims that the significance of the car in Tekin’s Swords of Ice and Saramago’s “Embargo” can be explained through the theoretical lens provided by the new materialisms. In order to explore ideas on the subject-object interactions and elucidate the independent and autonomous life of things, this article will first briefly refer to the theories of new materialisms, and then read works of fiction by Latife Tekin, and José Saramago concentrating on the agency and power of the car as a quasi-object in both texts.
BATILAŞMA DÖNEMİNDE İSTANBUL’DA RUM CEMAATİNİN EĞİTİMİ
Authors: LIAZOS Nıkolaos
Published: March 2021

Osmanlı İmparatorluğu’nun demokratikleşmesinin bir parçası olarak ve büyük güçler baskısı altında, Sultan Abdülmecit döneminde 1856 tarihli Islahat Fermanı’yla reformlar ilan edildi. Islahat Fermanı, 19. yüzyıl Osmanlı toplumunu oluşturan ve ayrıcalıkları yeniden teyit edilen gayrimüslim cemaatlerin yeniden örgütlenmesine vesile oldu. Gayrimüslim cemaatleri ilk defa iç işlerini yeniden düzenlemek için kendi meclislerini kurmaya davet edildi. İstanbul dahil Rum Milletine mevcut kiliseleri ve hastaneleriyle beraber yeni okullar inşa edip eski binalarını onarabilme imkânı tanındı. Aynı zamanda fermanla, büyük bir yenilik olarak, cemaat okullarının kurulmasına izin verilerek, öğrencilerine ilköğretimden sonra yükseköğrenim görme hakkı tanındı. Osmanlı İmparatorluğu’nda, özellikle Tanzimat (1839), Islahat (1856) ve II. Abdülhamit reformlarından sonra İstanbul’daki Rum öğrencileri için daha modern bir eğitimin imkânı sağlandı.

Published: March 2021

Dada a relevância das ações de fortalecimento da agricultura familiar como estratégia de combate à fome, a pobreza e a insegurança alimentar, o presente artigo busca compreender como a pandemia COVID-19 incidiu sobre os espaços de comercialização direta da agricultura familiar na região do Vale do Rio Pardo (RS), indicando os desafios vividos e as repercussões para o abastecimento da população. O trabalho foi realizado entre abril e agosto de 2020, tendo como base uma metodologia exploratória, com levantamento de dados qualitativos e quantitativos, através de fontes primárias e secundárias. Os resultados indicam que a maioria das feiras locais permanece ativas graças a mobilização dos agricultores em implementar uma série de medidas para evitar o contágio, seja em suas práticas pessoais, seja nos espaços de comercialização. Houve também uma atuação positiva de organizações governamentais locais frente às famílias agricultoras, não havendo registros de contágio nas pessoas envolvidas nas dinâmicas de abastecimento estudadas. A caracterização e a distribuição sócio-espacial das feiras da agricultura familiar da região são um resultado inédito e importante para uma agenda de pesquisas futuras.
Evaluación de la resistencia a la flexión de limas rotatorias Protaper Gold, 2Shape, V-Taper Fanta Gold
Authors: Matumay-Santos Fabiola del Pilar , Cabrera Iberico Miguel Ángel
Published: March 2021

Antecedentes: Las limas rotatorias de níquel-titanio con tratamiento termomecánico se desarrollaron para permitir una mayor flexibilidad al instrumentar los conductos radiculares. Los instrumentos permitieron a los operadores tratar las curvaturas de los conductos con mayor facilidad. Los fabricantes están tratando de producir limas que funcionen de manera más eficiente y segura. Conocer las propiedades de las limas comercializadas es especialmente importante porque ayuda a elegir un sistema de lima apropiado. El objetivo de este estudio fue evaluar la flexibilidad de tres limas diferentes de níquel-titanio (NiTi) con tratamiento termomecánico en dos puntos diferentes. Materiales y métodos: Se midió la flexibilidad de tres limas NiTi con tratamiento termomecánico (ProTaper Gold, 2Shape y V-Taper Fanta Gold). Cada lima fue sujetada a 3 mm y 7 mm (n = 10/longitud/lima) y se utilizó una máquina de ensayo universal para doblarla a una fuerza máxima. Todos los datos fueron analizados estadísticamente por análisis de varianza de una vía y prueba de Tukey post hoc (p = 0,05) para determinar cualquier diferencia significativa. Resultados: Se halló diferencias estadísticamente significativas (p < 0,05). En general, V-Taper Fanta Gold fue la más rígida, ProTaper Gold mostró los mayores valores de fuerza y su deformación fue significativamente más flexible. Conclusión: Las limas ProTaper Gold mostraron una mayor flexibilidad en comparación con las otras limas estudiadas.

Published: March 2021

La reabsorción cervical externa es un proceso patológico con una etiología no comprendida en su totalidad. Los posibles factores predisponentes son el tratamiento de ortodoncia, los traumatismos, el blanqueamiento interno, el bruxismo, entre otros. El blanqueamiento interno es una forma efectiva y mínimamente invasiva de blanquear dientes no vitales, con un riesgo asociado con reabsorción, que al no ser tratado podría provocar incluso la pérdida dentaria. Este reporte de caso describe el manejo de dos incisivos superiores con reabsorciones cervicales externas, que tienen como antecedente tratamiento de conducto y blanqueamiento interno.
