INTERLOCUÇÕES ENTRE LA MULTIPLICACIÓN DRAMÁTICA - EDUARDO PAVLOVSKY - E O ARCO-ÍRIS DO DESEJO - AUGUSTO BOAL
Authors: De Oliveira Douglas Henrique , Bortolini Neide Das Graças de Souza
Published: June 2021

Este artigo faz aproximações entre práxis teatrais desenvolvidas no contexto latino-americano de resistência aos regimes ditatoriais no século XX, nos âmbitos artístico, educacional, social e terapêutico, constituídas de poéticas políticas criadas por Eduardo Pavlovsky, na Argentina, e Augusto Boal, no Brasil. Essas epistemologias marcaram o pensamento estético e projetaram-se internacionalmente, uma vez que os autores foram exilados por suas expressões críticas e libertárias na área teatral. São trajetórias distintas que se aproximam especialmente pelo caráter de transformações sociais, políticas e interpessoais realizadas por estéticas de resistência na conjuntura das ditaduras latino-americanas. O argentino Pavlovsky desenvolve, entre outras importantes realizações, a abordagem La multiplicación dramática (1989), enquanto o brasileiro, partindo de seu Teatro do Oprimido, desenvolve O arco-íris do desejo: método Boal de teatro e terapia (1992), trabalhos que se assemelham por serem abordagens grupais terapêuticas que implicam mudanças psicossociais. Palavras-chaveTeatro.

JOGO, CURIOSIDADE E AD-MIRAÇÃO: INDÍCIOS DE APROXIMAÇÃO ENTRE A PEDAGOGIA DA AUTONOMIA FREIREANA E A PEGADOGIA DO TEATRO
Authors: Bezerra de Souza Henrique
Published: June 2021

O presente artigo investiga a aproximação entre a noção de autonomia – tal como cunhada por Paulo Freire – e a prática do jogo em processos de ensino-aprendizagem em teatro. Para tanto, tece uma breve apresentação das ideias do educador pernambucano a respeito do processo de construção de conhecimento para, em seguida, relacionar tais reflexões a elementos presentes na prática do jogo. Na tentativa de encontrar os primeiros indícios dessa aproximação, toma como ponto de partida as características que Johan Huizinga atrela ao ato de jogar e, em seguida, analisa os jogos teatrais de Viola Spolin, buscando neles similaridades ao pensamento freireano. Nesse trajeto, se depara com desdobramentos que trespassam a metodologia realizada em sala de aula, revelando a importância da postura do sujeito docente no processo pedagógico. Palavras-chaveAutonomia.

Cet article propose une description et une théorisation du travail dramaturgique réalisé par Marion Boudier aux côtés de l’auteur-metteur en scène Joël Pommerat pour la création de Ça ira (1) Fin de Louis (créé en 2015 et présenté à la Mostra Internacional de Teatro de São Paulo en 2016). Comment travailler à partir des archives de la Révolution française pour accompagner un auteur-metteur en scène qui écrit ses textes avec la scène pendant les répétitions ? Marion Boudier présente ce qu’elle nomme une « dramaturgie prospective et documentaire ». Cet accompagnement de l’écriture se distingue des pratiques classi- ques de la dramaturgie. En effet, pour entrer en écriture, Joël Pommerat a dirigé ses comédiens dans des improvisations longuement préparées et nourries par une importante documentation historique : plutôt que d’éclairer un texte préalable en vue de son passage à la scène, le travail dramaturgi- que consiste alors, dans ce cas, à propo- ser une matière documentaire pertinente pour le sujet choisi et potentiellement riche pour le théâtre, puis à réagir à ses évolutions scéniques. Ainsi cette dramaturgie est une sorte d’enquête, menée au service de l’auteur-metteur en scène et de ses comé- diens tout au long du processus de création.Mots-clésDramaturgie. Prospection.

ON DANCE DRAMATURGY
Authors: Cools Guy
Published: June 2021

In 1994, Marianne Van Kerkhoven, the Flemish godmother of dance dramaturgy wrote a short, seminal article on the subject – Looking without pencil in the hand – of which the title alone is already a manifesto. This contribution builds further on Van Kerkhoven insights’: how the dramaturge has to stay necessarily invisible in the creative process (s)he is supporting; how in order to capture this invisible role, a lot of metaphors have been created. It continues with looking at the different roles I take up in my own practice: that of somatic witness, dialogue partner and editor. It concludes reasserting the practice of the (dance) dramaturge as a creative practice in which the whole body is involved and in which somatic proximity to the creative process is as important as critical distance. Key wordsDance dramaturgy. Somatic witness. Dialogue partner. Editor.
Advanced controller design for uncertain linear systems with time-varying delays via augmented zero equality approach
Authors: Lee YongGwon , Kim Youngjae , Kim Seungho , Lee Seunghoon , Park Myeongjin , Kwon O. M.
Published: June 2021

This paper deals with the stability analysis and controller design for
linear systems with time-varying delays and parameter uncertainties. By
choosing appropriate augmented Lyapunov-Krasovskii functionals, a set of
Linear Matrix inequalities is derived to get advanced feasible region of
stability, and controller gain matrices which guarantee the asymptotic
stability of the concerned systems within maximum bound of time-delays
and its time-derivative. To further reduce the conservatism of
stabilization criterion a recently developed mathematical technique
which constructed a new augmented zero equality is applied. Finally, two
numerical examples are utilized to show the validity and superiority of
the proposed methods.
Numerical analysis of viscoelastic pipe with variable fractional order model based on shifted Legendre polynomials algorithm
Authors: Jin Suhua , Chen Yiming , Wang Yuanhui
Published: June 2021

In this paper, an valid numerical algorithm is presented to solve
variable fractional viscoelastic pipes conveying pulsating fluid in the
time domain and analyze dynamically the vortex-induced vibration of the
pipes. Firstly, Coimbra variable fractional derivative operators are
introduced. Meanwhile, using Hamilton’s principle and a nonlinear
variable fractional order model, the governing system of equations is
established. The unknown functions of the system of equations are
approximated with shifted Legendre polynomials. Then, convergence
analysis and numerical example investigate the effectiveness and
accuracy of the proposed algorithm. Finally, the influences of different
parameters on the dynamic response of the viscoelastic pipe are studied.
The influencing factors and their ranges of the transient and long-term
chaotic states of the pipe are analyzed. In addition, the proposed
algorithm shows enormous potentials for solving the dynamics problems of
viscoelastic pipes with the variable fractional order models.
Patterns of infection, origins and transmission of ranaviruses among the ectothermic vertebrates of Asia
Authors: Herath Jayampathi , Ellepola Gajaba , Meegaskumbura Madhava
Published: June 2021

Ranaviral infections, a malady of ectothermic vertebrates, are becoming
frequent, severe, and widespread, causing mortality among both native
and cultured species, raising odds of species extinctions and economic
losses. This turn of events is possibly due to the broad host range of
ranaviruses and the transmission of these pathogens through regional and
international trade in Asia, where outbreaks have been increasingly
reported over the past decade. Here we focus attention on the origins,
means of transmission, and patterns of spread of this infection within
the region. Infections have been recorded in both cultured and wild
populations in at least twelve countries/administrative regions,
together with mass die-offs in some regions. Despite the imminent
seriousness of the disease in Asia, surveillance efforts are still
incipient. Some of the infections transmitted within Asia may transmit
across host-taxon barriers, posing a significant risk to native species.
Factors such as rising temperatures due to global climate change seem to
exacerbate ranaviral activity, as most known outbreaks have been
recorded during summer; however, data are still inadequate to verify
this for Asia. Import risk analysis, using protocols such as Pandora+,
pre-border pathogen screening, and effective biosecurity measures, can
be used to mitigate introduction to uninfected areas and curb
transmission within Asia. Comprehensive surveillance using molecular
diagnostic tools for ranavirus species and variants will help in
understanding the prevalence and disease burden in the region. This is
an important step towards conserving native biodiversity and
safeguarding the aquaculture industry.
A clinical practice for the hippocampal neurogenesis by chronobiological therapy
Authors: Shiozawa Masaki , Watanabe Kenjiro
Published: June 2021

Background: In 1965 Altman achieved the hippocampal neurogenesis in
rats. In addition, when enough activities are provided in the daytime,
and it is suggested that the consolidation of the memory during sleep
will be achieved by hippocampal neurogenesis. Aims: We show a recovery
method about dementia of neurodegenerative diseases on this article. We
introduce our clinical practice of the chronobiological therapy
regarding 6 dementia cases. Method: We provided the chronobiological
therapy based on awakening-sleep rhythm by daily medical care. We
examined autonomic nervous disorders and fluctuating cognition using
physical examination. We performed the medication to promote the changes
from sleep to awakening-activities in morning. In daytime, our
occupational therapy was set, and awakening-activities was made stable.
At night we gave the medication to make an active state decreased and
stabilize deep sleep. The clinical evaluation was carried out by
psychological examination. And Voxel-based Specific Regional Analysis
System for Alzheimer’s Disease (VSRAD) of Magnetic Resonance Imaging
(MRI), which had been already established, was performed. The
conventional study in VSRAD showed the state that the brain atrophy was
progressive. Results: About Z-score showing the hippocampal atrophy in
VSRAD we accomplished the improvement of 1.28 points from 0.03 about six
dementia cases by the chronobiological therapy. These improvements were
accompanied by the better changes of the cognitive functions.
Conclusion: We speculate that the hippocampal neurogenesis may be
derived by reconstructing awakening-sleep rhythm using the
chronobiological medicines. If neurogenesis is more dominant than
neurodegeneration, dementia associated with the neurodegeneration can be
treated.

Authors: Yücesan Ayşe Gül , Ateş Vidan Sena , Yasin Yeşim , Demir Figen
Published: June 2021

Background Medical students are at the core of pandemic response as
prospective health professionals. This study aimed to assess medical
students’ knowledge, attitude, and practices toward the COVID-19
pandemic and measure their level of adaptation to infection control
measures. Methods In this descriptive study, data was collected via an
internet-based questionnaire delivered to students through e-mail
between 19 August-14 September 2020. Participants were students enrolled
in medical school in Istanbul, Turkey. Descriptive statistics and
Chi-Square test were used to analyze data. Results Among 245 subjects
enrolled in the study, the mean age was 21.8±1.7, and 58.0% were
female, 49.0% were preclinical (1-2-3rd) grades. Most of the
respondents (85.3%) thought they have enough knowledge; 97.6% knew
about transmission routes. 31.8% of students used the World Health
Organization website, 22% of the students used official government
websites, and 20.0% of students used the news as a primary source for
covid-related information. More than half of the students (60.8%) felt
more anxious and nervous than usual due to pandemic, with female
predominance. Over 85.0% of students fulfill infection control and
preventive measures, such as wearing masks, washing hands, maintaining
social distancing, and avoiding being in crowds. 68.2% of the students
were following current guidelines prepared for COVID-19. We observed
more frequent behaviors in students who report more anxiety and
nervousness than usual. Most of the students (84.9%) expressed that
they would be vaccinated when the vaccine is developed. Conclusions
Mostly, medical students were well-informed with expected levels of
knowledge, attitude, and preventive measures towards COVID-19.
Anxiety-reducing interventions are urgently needed for medical students.
Furthermore, pandemic management should be included in the medical
school curriculum to increase knowledge, awareness, and protective
behavior.

Authors: Vajnhandl Simona , Skodic Lidija , Simonic Marjana , Lobnik Aleksandra , Volmajer-Valh Julija
Published: June 2021

In this work, the treatment efficiency of advanced oxidation processes H2O2/UV enhanced by the addition of a manganese catalyst complex (MnTACN) was investigated on a model dye solution and a real dye-house effluent. The experimental results were evaluated in terms of absorbance (A) and total organic carbon (TOC) reduction. The major degradation products of the model dye solution were identified by high resolution gas chromatography/mass spectrometry analyses. In addition, the toxicity of the final reaction solution after H2O2/UV/MnTACN treatment to Vibrio fischeri bacteria was determined. The results showed that the addition of the H2O2/UV/MnTACN system at different concentrations of the catalyst solution increased the decolourisation rate compared to H2O2/UV for both the model dye solution and real dye-house effluent.

Authors: Manikandan Srinivasan , Dharmakkan Nesakumar , Sumana Nagamani
Published: June 2021

The experimental study of the heat transfer coefficient of nanofluid plays a significant role in improving the heat transfer rate of the heat exchanger. A natural convection apparatus was used to study heat transfer in the suspension of Al2O3 nanoparticles in a water-ethylene glycol mixture base fluid. The effects of the heat input, the nanoparticle volume fraction, and the base fluid concentration on the heat transfer coefficient were studied using a 23 full factorial design matrix (16 experimental runs) and the MINITAB Design software. The levels for the heat input, nanoparticle volume fraction, and base fluid concentration were 10 and 100 W, 0.1 and 1 vol.%, and 30 and 50 vol.%, respectively. The residual, contour, 3D surface plots, and Pareto chart were drawn from the experimental results. The observed heat transfer coefficient showed the highest enhancement with the high level of the nanoparticle volume fraction and a moderate enhancement with the high level of heat input, and a slight enhancement with the base fluid concentration.
Oxidation of cycloalkene using supported ruthenium catalysts under solvent-free conditions
Authors: Alsaiari Raiedhah
Published: June 2021

The present paper employs supported ruthenium nanoparticles alongside catalytic quantities of the radical initiator, which are proven to be capable of cyclooctene oxidation with green conditions, in the absence of solvent, with air as the main oxidant and without sacrificial reductant. The paper examines the effects of a range of radical initiators and how the products are distributed over time. Furthermore, the paper addresses the reaction pathways to the epoxides and allylic alcohol, the latter being the primary by-product, whilst also analysing the impact of the technique of synthesis, reaction time, and various supports. Catalyst activity can be markedly improved by adopting a sol-immobilisation technique to synthesise the catalysts, with retention of selectivity to the epoxide.
Physicochemical characterisation of dihydro-alpha-lipoic acid interaction with human serum albumin by multi-spectroscopic and molecular modelling approaches
Authors: Gligorijevic Nikola , Sukalovic Vladimir , Minic Simeon , Miljus Goran , Nedic Olgica , Penezic Ana
Published: June 2021

The binding of a popular food supplement and well-known antioxidant, dihydro-alpha-lipoic acid (DHLA) to human serum albumin (HSA) was characterised. The binding was monitored by several spectroscopic methods together with the molecular docking approach. HSA was able to bind DHLA with moderate affinity, 1.00?0.05?104 M-1. Spectroscopic data demonstrated that the preferential binding site for DHLA on HSA is IIA (Sudlow I). Both experimental and molecular docking analysis identified electrostatic (salt bridges) and hydrogen bonds as the key interactions involved in DHLA binding to HSA. Molecular docking confirmed that the Sudlow I site could accommodate DHLA and that the ligand is bound to the protein in a specific conformation. The molecular dynamic simulation showed that the formed complex is stable. Binding of DHLA does not affect the structure of the protein, but it thermally stabilises HSA. Bound DHLA had no effect on the susceptibility of HSA to trypsin digestion. Since DHLA is a commonly used food supplement, knowledge of its pharmacokinetics and pharmacodynamic properties in an organism is very important. This study further expands it by providing a detailed analysis of its interaction with HSA, the primary drug transporter in the circulation.
Industry Norm, Legitimacy Threats, and Managerial Decision-Making: An Experimental Investigation of Environmental Capital Expenditure Projections
Authors: Olczak Wioleta , Patten Dennis M.
Published: June 2021

We investigate a phenomenon documented in Patten (2005) and J. Chen, J. Chen, and Patten (2014) regarding the overstatement of projections of future environmental capital expenditures (ECE) by firms operating in environmentally sensitive industries. Given that overstatement of ECE seems to be a common practice within these industries, we use an experimental design to examine whether two factors—an overstatement industry norm and/or a legitimacy threat—impact the likelihood of managers making higher ECE projections. Our results show participants are more likely to choose higher ECE projections in the presence relative to the absence of an overstatement industry norm. However, in contrast to expectations, the presence of a legitimacy threat was not significantly associated with higher projected spending. These findings provide additional understanding of what may drive managers' behavior regarding environmental disclosure decisions.

Published: June 2021

We previously reported that
genotype-phenotype correlations in 12 missense variants causing severe insulin
resistance, located in the second and third fibronectin type III (FnIII)
domains of the insulin receptor (INSR), containing the α-β cleavage and part of
insulin-binding sites. This study aimed to identify genotype-phenotype correlations in FnIII domain variants of
IGF1R, a structurally related homolog of INSR, which may be associated with growth retardation, using the recently
reported crystal structures of IGF1R. A structural bioinformatics analysis of five
previously reported disease-associated heterozygous missense variants and a
likely benign variant in the FnIII domains of IGF1R predicted that the disease-associated variants would severely impair the hydrophobic core
formation and stability
of the FnIII domains or affect the α-β cleavage site, while the likely benign variant would
not affect the
folding of the domains. A functional analysis of these variants in
CHO cells showed impaired receptor processing and autophosphorylation in cells expressing the disease-associated
variants, but not in those expressing the wild-type form or the likely benign
variant. These results demonstrated genotype-phenotype
correlations in the FnIII domain variants
of IGF1R, which are presumably
consistent with those of INSR and would help in the early
diagnosis of patients with disease-associated IGF1R variants.
Joining Analysis of Polypropylene Parts in Rotary Friction Welding Process and Developing of Joints Profile
Authors: MADEN Hakan , ÇETİNKAYA Kerim
Published: June 2021

Various welding methods are used to produce non-detachable joints of plastic parts. These are friction welding (FW), friction-stir welding (FSW), ultrasonic welding, chemical bonding, and hot plate welding. Rotary friction welding (RFW) method, which is one of the FW methods, is generally used in joining the filter parts of water treatment devices. After RFW processes, semi-melted plastic accumulations tend to occur on the interior surfaces of the filter parts. In some cases, particles broken off from these accumulations can often clog sensitive filters. In this study, it is aimed to develop a welding joint profile design that can be used to confine the semi-melted agglomeration formed in the interior surfaces of the filter parts. For this purpose, the semi-melted agglomeration in the filter parts is analyzed/simulated utilizing the ABAQUS program by using Lagrangian and CEL (Coupled Eulerian-Lagrangian) methods, and their thermal analysis, stress, and energy data are evaluated. The analysis is repeated until the optimal welding structure design to confine the semi-melted agglomeration is developed. As a result of the analyses, it was determined that the maximum temperature reached is 166.2 °C, there was a 1.98 mm shortening in the length of the product after welding, and the temperature of 150 °C was reached in 13.1 milliseconds. From the several joint profile designs proposed, it was determined that the N3 joint profile design accommodates the semi-melt raw material better than the others.

Authors: Ula Restu Yanuar , Sarkadi Sarkadi , Badrujaman Aip
Published: June 2021

Improving the quality of education is based on the formation of the quality of learning through teacher competence in managing the classroom. However, the problem is that the learning outcomes of history are still relatively low because the competence of teachers in applying the method is still monotonous. On the other hand, the VCT learning model can provide creative-critical power, foster positive attitudes, interests, and values in students in learning history. Therefore, this study aims to determine the effect of the Value Clarification Technique learning model on student learning outcomes of history. The research method used quantitative methods with a quasi-experimental design. The research design used was the Non-Equivalent Pretest-Posttest Design. The population in this study was all students of grade XI. At the same time, the sampling technique is purposive sampling which is divided into two classes into the experimental group and the control group. The results of this study indicate that the VCT learning model affects student learning outcomes in history learning.

PECULIARITIES OF FAKE MEDIA MESSAGES (ON THE EXAMPLE OF RUSSIAN FAKES ABOUT UKRAINE)

Information wars have long been used as a full-fledged weapon against the enemy, using both manipulation and completely fake messages. The methods used to disseminate false media messages by their authors are completely different, but the goal is almost always the same - to make the target audience that consumes information, believe and be influenced. Scientists have identified three main elements of the media chain: the author of the message - the transmission channel - the recipient of the message. According to M. McLuhan, media channels of information transmission are a technical continuation of natural channels: radio (auditory), printed periodicals (visual), television (combination of vocal and visual), and Internet MMC (combination of auditory, optic and visual). Therefore, it is worth considering the ways in which fakes are distributed - through photos, videos or just texts. Very often two or sometimes three distribution channels are used, because video can accompany text and attached to it photos, so this division should be considered conditional. Having analysed fake reports from the Russian-language media segment, it became possible to draw conclusions about the use of basic evaluation criteria according to professional journalistic standards of publications. The emotionality of the texts, which was conditionally divided into two groups - "excessive emotionality" and "moderate neutrality" was taken into account. As for the excessive emotionality of the texts, it has been determined that it is most common in the video, a little less in the photo, and very little in the texts. As to the studies concerning the topic of fakes in the Russian-language media segment, a vast majority of studies concerned Ukraine, and military issues namely. Usually, the authors of fake media reports aim to destabilize the situation, and to make the target audience believe in nonsense and behave predictably, to divert attention from their own problems.

Recent progress relevant to wood-plastic composites has been reviewed in this article. The process and technological aspects of WPC, such as raw materials, fabrication, mechanical, physical, thermal, and morphological properties, were outlined comprehensively. The manufacturing process of WPCs is an important aspect of WPCs production. Manufacturing methods like compression molding and pultrusion have some limitations. Extrusion and injection molding processes are the most widely used in WPCs due to their effectiveness. Recent developments dealing with WPCs and the use of different kinds of nanofillers in WPCs have also been presented and discussed. Nanoclays are widely used as nanofillers in WPCs because they represent an eco-friendly, readily available in large quantity, and inexpensive filler. WPCs can be found in a wide range of applications from construction to the automotive industry.Keywords: additive manufacturing, adhesion, fabrication techniques, mechanical and physical properties, wood-plastic composites
