Modeling and Numerical Simulation of Laminated Thermoplastic Composites Manufactured by Laser-Assisted Automatic Tape Placement
Authors: Ausias G. , Dolo G. , Cartié D. , Challois F. , Joyot P. , Férec J.
Published: February 2021

A comprehensive numerical model is developed for the simulation of the laser-assisted automated tape placement process of carbon fiber/thermoplastic composites. After being heated with a laser, the thermoplastic is welded with the help of a consolidation roller onto a substrate made up of layers of tapes bonded onto one another. Under the pressure applied by the roller, the thermoplastic flows and the tape reaches its final thickness. The numerical model is developed in three sequential steps that can be used to identify the required pressure and temperature distribution to achieve a good bond. Firstly, a heat transfer simulation is performed to determine the temperature distribution into the incoming tape under the consolidation roller. Secondly, a rheological model is developed to examine the polymer flow under the roller and to obtain the pressure field. Finally, the consolidation level between the substrate and the tape is investigated through the degree of intimate contact, which is related to the processing parameters such as the roller velocity, the laser power density and the compaction force.
Know Yourself in the Mirror of the Word: Kierkegaard on Self-Knowledge
Authors: Kolínská Kateřina
Published: February 2021

The article provides a reconstruction of Kierkegaardʼs conception of self-knowledge, mainly in the light of The Concept of Irony, The Sickness unto Death, Philosophical Fragments and selected upbuilding discourses. The concept of self-knowledge, which in Kierkegaard goes beyond mere epistemology, is shown in its duality, as a process which is for Kierkegaard both substantial and relational: to know oneself is for Kierkegaard both an ethical claim upon man and a religious act whose accomplishment is dependent on Godʼs intervention. The article next discusses how self-knowledge involves a relationship to and “knowledge” of God. Finally, it is shown that self-knowledge presupposes not only that one believes himself or herself to be known by God, but also by his or her fellow human beings: self-knowledge requires engagement in the lived world and with others.
The Mutiny of the Pseudonyms in the Kierkegaardian Authorship
Authors: Lopes Paulo Henrique
Published: February 2021

The essay emphasizes the unsolvable tension between activity and passivity implied in Kierkegaard’s reduplication as an author of authors. To characterize the different approaches to pseudonymity, I will use the term Halvbefaren [the inexperienced seaman] to refer to a reading that appeals only to Kierkegaard’s or to the pseudonyms’ authority over the authorship, and Helbefaren [the experienced seaman] to refer to another interpretation that recognizes that unsolvable tension between them. Recurring to the sailing metaphor implicit in these terms that appear in Climacus’ Postscript, I defend the thesis that the pseudonyms open the authorship from within, overcoming Kierkegaard as a usual author, as the only captain of the entire authorship. The mutiny performed by the pseudonyms cannot be resolved by simply transferring the authority to the pseudonyms themselves, and it creates a subjective space in the authorship so it becomes a matter of the experience of the reader.
Effects of welding parameters on tensile properties and fracture modes of resistance spot welded DP1200 steel
Authors: Elitas Muhammed
Published: February 2021

In this study, the maximum tensile shear load bearing capacity and fracture modes of resistance spot welded DP1200 steel were investigated, and the tensile shear properties of the joints were evaluated. The effects of different welding parameters on tensile shear properties, fracture modes, microstructure, microhardness, and heat affected zone softening were examined. Weld processes were performed by using 2 to 6 bar electrode pressure as well as 5 and 7 kA weld currents. The microstructure of resistance spot welded materials was evaluated, and the hardness profiles were determined. Experimental results showed that welding current and electrode pressure had a significant effect on the load-displacement characteristics of DP1200 welds. Three different fracture modes were observed in the tensile shear loads. It was also observed that the expulsion had a negative effect on the tensile shear properties.
Investigation of wear on the upper edges of webs of thin-film coated single-screw extruders processing pure polymers
Authors: Buttler Torben , Hamje Jens , Reiter Rolf , Wesling Volker
Published: February 2021

During polymer extrusion there are a variety of situations in which the screwthread of the extrusion screw has an unlubricated metal-to-metal contact with the barrel wall. At the same time the screw coating is subjected to the highest loads. The combination of a secondary hardening cold work steel 1.2379 and a chromium nitride coating deposited by ARC-PVD, which is frequently used in polymer processing, is characterized and investigated. The characterization is done by metallographic examination, SEM and CLSM. The tests were performed on a pin-on-disk and a pin-roll test rig. Different roughness levels were tested on the pin-on-disk test, where massive differences in wear behavior were found. A hybrid surface structure is proposed to optimize the tribosystem. On the pin-on-disk test stand, rollers made of the same material pairing were tested. The test speed was varied to highlight differences and similarities between the tribological systems. A wear minimization of 50 % was achieved and the similarities between the tribological systems were highlighted. In addition, the investigations led to the development of a new model thesis which provides a reason for the development of stippling on the screw when processing polycarbonate.

Authors: Alagarsamy Sivasamy , Ravichandran Manickam
Published: February 2021

The present study was carried out to analyze the effect of process parameters during EDM machining of AA7075-10 wt.-% TiO2 aluminum matrix composite (AMC). The composite was produced through stir casting. The EDM process parameters such as the electrode material (Cu, Br, EN-8), pulse current (5, 10 and 15 A), pulse ON time (300, 600 and 900 μs) and pulse OFF time (30, 60 and 90 μs) were chosen to study the effects on material removal rate, surface roughness and the electrode wear ratio. The experiment was carried out as per L27 orthogonal array based on Taguchi’s design of experiments. Signal-to-noise ratio and analysis of variance were used to identify the contribution of each input parameters on the output responses of the EDM process. The experimental results shows that pulse ON time and pulse current are the most significant factors for the material removal rate; pulse ON time and electrode material are the most influencing parameters for surface roughness and the electrode wear ratio.
The corrosion behavior of marine aluminum alloy MIG welded joints in a simulated tropical marine atmosphere
Authors: Gong Lihua , Guo Weimin , Pan Feng
Published: February 2021

The influence of metal inert-gas arc welding (MIG) on the corrosion behavior of 6061-T6 aluminum alloy in a simulated tropical marine atmospheric environment (related to high temperature, high humidity and high salt spray) were examined by dry-wet alternate immersion corrosion tests. The equivalent conversion was used to design the accelerated test time. The results show that in the initial stage, the intermetallic compound, rich in Fe, Si and Cu, had little influence on corrosion resistance in the heat-affected zone. For a corrosion time of 3 days in a tropical marine atmospheric environment, the corrosion rate of the welded joint increased rapidly, even reaching 3.5 times that of the base metal. Though the corrosion products had significant impact on slowing down the corrosion rate, as with the base metal, the corrosion rate of the welded joint was nearly double that of the base metal during the longest cycle period involving alternate immersion corrosion tests for 20 days.
Idioms in Context: Evidence from a Time Cloze-Response Study
Authors: Kędzierska Hanna , Błaszczak Joanna , Klimek-Jankowska Dorota , Gulgowski Piotr , Witkowski Wojciech
Published: February 2021

This article reports on two timed cloze-response experiments which examine the impact of context on idiom recognition. Study 1 presented participants with the beginnings of Polish VP idioms without any prior context. Cloze probabilities and response times for idiom continuations were measured to establish the idiom recognition point (IRP) for each idiom. In Study 2, we used the same idioms in two kinds of contexts: (i) supporting a figurative meaning and (ii) supporting a literal meaning. Cloze probability and response times were measured at the IRP and one word before and after it. The figurative meaning of idioms was automatically activated at the IRP independently of the type of context. Additionally, the figurative context did not move the IRP to an earlier position, whereas in the literal context the responses were significantly slower at the IRP as compared to the figurative context condition. Such a finding indicates that, irrespective of the literal context, the comprehenders automatically activated the figurative meaning of an idiom at the IRP, but they had to discard it later. The literal meaning was computed from the literal meanings of idiom constituents stored in idiom lexical representation, which was computationally costly.
Between Power and Love: Pilate’s Transformation in The Master and Margarita
Authors: Vladislavovich Bosnak Dmitry
Published: February 2021

The conventional reading of the “ancient” chapters of Bulgakov’s The Master and Margarita attributes the role of an active moral subject to Pilate and a largely passive role to Ieshua. Proceeding from this assumption, the encounter between these characters is interpreted as an ethical event, in which Pilate is supposed to make decisions based entirely on his own will. This paper challenges this reading by arguing that Ieshua, generally considered the epitome of love, is the actual source of the events in which Pilate is involved. This idea is demonstrated by a comparison with the early Christian experience that views divine love as prior to power and intellect. The analysis traces Pilate’s inner transformation caused by the impact of proactive love and of the actual person of Ieshua, rather than his ideas, which clarifies the meaning of the encounter of these protagonists in Bulgakov’s novel.
The Phosphoprotein Synapsin Ia Regulates the Kinetics of Dense-Core Vesicle Release
Authors: Yang Hui-Ju , Chen Pin-Chun , Huang Chien-Ting , Cheng Tzu-Lin , Hsu Sheng-Ping , Chen Chien-Yu , Lu Juu-Chin , Wang Chih-Tien
Published: February 2021

Common fusion machinery mediates the Ca2+-dependent exocytosis of synaptic vesicles (SVs) and dense-core vesicles (DCVs). Previously, Synapsin Ia (Syn Ia) was found to localize to SVs, essential for mobilizing SVs to the plasma membrane through phosphorylation. However, whether (or how) the phosphoprotein Syn Ia plays a role in regulating DCV exocytosis remains unknown. To answer these questions, we measured the dynamics of DCV exocytosis by using single-vesicle amperometry in PC12 cells (derived from the pheochromocytoma of rats of unknown sex) overexpressing wild-type or phosphodeficient Syn Ia. We found that overexpression of phosphodeficient Syn Ia decreased the DCV secretion rate, specifically via residues previously shown to undergo calmodulin-dependent kinase (CaMK)-mediated phosphorylation (S9, S566, and S603). Moreover, the fusion pore kinetics during DCV exocytosis were found to be differentially regulated by Syn Ia and two phosphodeficient Syn Ia mutants (Syn Ia-S62A and Syn Ia-S9,566,603A). Kinetic analysis suggested that Syn Ia may regulate the closure and dilation of DCV fusion pores via these sites, implying the potential interactions of Syn Ia with certain DCV proteins involved in the regulation of fusion pore dynamics. Furthermore, we predicted the interaction of Syn Ia with several DCV proteins, including Synaptophysin (Syp) and solubleN-ethylmaleimide-sensitive factor attachment receptor (SNARE) proteins. By immunoprecipitation, we found that Syn Ia interacted with Syp via phosphorylation. Moreover, a proximity ligation assay (PLA) confirmed their phosphorylation-dependent,in situinteraction on DCVs. Together, these findings reveal a phosphorylation-mediated regulation of DCV exocytosis by Syn Ia.

SIGNIFICANCE STATEMENTAlthough they exhibit distinct exocytosis dynamics upon stimulation, synaptic vesicles (SVs) and dense-core vesicles (DCVs) may undergo co-release in neurons and neuroendocrine cells through an undefined molecular mechanism. Synapsin Ia (Syn Ia) is known to recruit SVs to the plasma membrane via phosphorylation. Here, we examined whether Syn Ia also affects the dynamics of DCV exocytosis. We showed that Syn Ia regulates the DCV secretion rate and fusion pore kinetics during DCV exocytosis. Moreover, Syn Ia-mediated regulation of DCV exocytosis depends on phosphorylation. We further found that Syn Ia interacts with Synaptophysin (Syp) on DCVs in a phosphorylation-dependent manner. Thus, these results suggest that Syn Ia may regulate the release of DCVs via phosphorylation.

Since the first outbreak of SARS-CoV-2 worldwide, research on modeling and simulation has grown, particularly to estimate the peak and end time of the pandemic which has been exceeded in some cases. This study aims to model the current virus spread with discrete event simulation, using the case of Jakarta. About 2 million of Jakarta's susceptible population  was used for the the model's input which ran for a year. The data was obtained from past records and were divided into three main timelines (i.e. initial stage, large scale restriction and new normal) in order to validate the model with real cases step by step. Scenario analysis was then performed by evaluating five possible interventions such as: existing scenarios, social  and health intervention, mass vaccination and hybrid intervention. The results show that the model represents real cases with a variation of less than 5% during the timeline. Furthermore, scenario analysis showed that mass vaccination, hybrid and social intervention  provide the least positive cases in the system. This study recommends that hybrid intervention should be used while the vaccine is being mass produced, and the implementation of social intervention should be highlighted.

The physical processes in the damping system of the salient-pole synchronous machine rotor, which cause the gradual destruction of its structure, have been studied. In particular, the distributions of currents, temperatures and thermomechanical stresses in the damping system rods during its operation in asynchronous and asymmetric modes of operation, as well as in case of rotor eccentricity. A field mathematical model has been developed that takes into account the combined action of three physical fields of different nature: electromagnetic, temperaturic, and thermomechanical stress fields, and allows estimating heating and thermomechanical loads in the damping system of the rotor of the salient-pole synchronous machine. According to the results of the analysis, the heating and thermomechanical loads of the structural elements were determined and recommendations for its structural improvement were given.

Published: February 2021

Neste artigo, propomos abordar, de maneira pontual, o seguinte enfoque: como falar do ‘outro’ como “outro” hoje na literatura contemporânea? Feito isso, analisamos uma possível poética do encontro de culturas, bem como sugerimos uma interpretação do mapa da estrangeiridade no romance Relato de um certo oriente (1989), de Milton Hatoum. Depois de enfocar tais aspectos, tecemos breves considerações sobre essa narrativa do autor amazônico, procurando ensaiar, testar e reapontar novas leituras de “um certo oriente” que dialogicamente possa ser vislumbrado na errância semântica proposta pelos pronomes para quê, quando, onde, como e por que falar da representação da estrangeiridade na cena contemporânea.
“El más importante asunto internacional”: Belice, el Imperio británico y la política exterior guatemalteca en la posguerra (1945-1948)
Authors: Véliz Estrada Rodrigo
Published: February 2021

En febrero de 1948 se desató un conflicto entre Guatemala y el Imperio británico que por poco llega a las armas. El problema giró en torno a Belice y se dio en el contexto del fin de la Segunda Guerra Mundial, cuando los británicos se sentían más vulnerables. Así, reaccionaron exageradamente a la activa, aunque caótica, estrategia del gobierno guatemalteco para recuperar el territorio. Gran Bretaña envió tropas y barcos de guerra a Belice, en medio del intento de Estados Unidos por crear una OEA de corte anticomunista. Archivos desclasificados de Gran Bretaña, Estados Unidos, México y nuevas cartas personales de altos funcionarios guatemaltecos ayudan a recrear este olvidado e ilustrador momento del inicio de la Guerra Fría en América Latina.

Palabras claves: Belice, Imperialismo británico, colonialismo, Revolución guatemalteca, Guerra Fría.

The Colonial Origins of the State in Southern Belize
Authors: Wainwright Joel
Published: February 2021

Recent research in Belizean historiography has improved our understanding of twentieth-century colonial state relations and the transition to the post-colonial authoritarian democratic state. Following a concise review of these works, I draw on archival documents to examine the origins of the British state in southern Belize. This analysis provides two principal findings. First, the earliest state institutions were founded at the behest of colonists from the defeated Confederate States to facilitate labor discipline over their workers. Once established, local state officials sought to learn about and gain influence over Indigenous communities. Second, the nascent colonial state was relatively authoritarian and inattentive to local accumulation and social needs. Thus from its inception, the state was organized around race and class relations.

Published: February 2021

The study of the managing methods represents particular interest in the biomechanics for the human body motor as well the opportunities for its improvement. (1) The basic problem related to the managing is to understand and to be aware of the task itself, the performance and the possibility for the reproduction. (2,3) Therefore the aim of this study is to try to determine the quantity of the basic parameters of the balanced resistance and also during the examination in order to influence the managing method. There were examined 85 individuals (33 women and 52 men) taking part in the test. The test battery includes performing of the supporting human body tasks on a stable graphic platform. The projections of the Gravity Centre have been studied and the task for the individuals submitted to the test is to manage the Gravity Center having their full conscience. During the performance a quantity difference has been observed and therefore we could establish the conclusions related to the degree of consciousness regarding the managing methods.
REACTIONS OF THE MOTOR SYSTEM IN LOCAL AND GLOBAL ACTIVITIES
Authors: Dimitrova Nikolina
Published: February 2021

The aim of the present study is to determine the relationship between the simple motor response and the reaction that occurs when solving a complex motor task. Three groups of 20 experienced persons were studied, respectively, from the gymnastics, judo and football disciplines. The sport reaction was determined by a standard light source test. Using the video computing methodology and the dynamo platform, the time interval Δt1 for the start of the motor action and the time interval Δt2 for the overall realization were determined. A random number generator is used to vary the time interval between the light signals. Stabilization of the mean score at all surveyed individuals was observed at the latest after the seventh trial. From the results of the variation analysis of the three groups of experienced people, the group of judokas, followed by the football players and the gymnasts, stands out with the best achievements. The character of a sport discipline develops in a specific way the speed of the motor response. Standard results could be used to determine the level of some aspects of the sport-technical mastery through biomechanical criteria for realization efficiency.
PHYSICAL ACTIVITY AND OLDER ADULTS
Authors: Tumanova Boryana
Published: February 2021

Physical activity among the older population of Bulgaria is a matter related to health prevention, improving the quality of life and recovery after illness. In this work, we present data from a study held with people aged 65-80 years, citizens of Sofia city. Our goal was to determine the place of physical exercise in their daily lives and the role of sports teacher for the formation of motivation in them for leading an active lifestyle. The analysis shows lack of information on the wide variety of motor activities suitable for this age group as well as low level of motivation for sport activities. We conclude that it is necessary to provide sources of information to the people of the third age, which will educate them about the benefits of the active way of life and what possibilities for access to various sports activities are there. Medium intensity workout or a daily walk outdoors would help not only to improve their fitness level but also to maintain the necessary mental health and social activity.

Published: February 2021

INTRODUÇÃO: A tuberculose (TB) é uma doença de caráter infectocontagiosa, de evolução crônica, causada pela Mycobacterium tuberculosis, Uma vez considerada como doença crônica entre idosos por poder gerar sequelas e resultar em comprometimento da capacidade pulmonar, e desta forma contribuir para um quadro clínico de pior prognóstico é essencial estudar a relação da TB com a síndrome da fragilidade e a capacidade funcional em idosos. OBJETIVO: Analisar a capacidade funcional de idosos com seqüela de TB Pulmonar e investigar a ocorrência de fragilidade nesta população. MATERIAIS E MÉTODOS: Trata-se de um estudo transversal com método quantitativo-correlacional, realizado no período de agosto a novembro de 2017, no ambulatório de fisioterapia do Hospital Universitário João de Barros Barreto, Belém/PA. Avaliou-se a fragilidade pelo instrumento Tilburg Frailty Indicator (TFI) e a capacidade funcional pelo “Teste de AVD-Glittre” (TGlittre). Utilizou-se a “correlação de Spearman” entre TFI e TGlittre. Adotou-se p-valor?0,05. RESULTADOS: Avaliaram-se 24 idosos com diagnóstico clínico de TB Pulmonar, apresentando alterações e/ou sequelas pulmonares. A média de idade foi de 68,37 +6,01anos, 66,7% era do sexo feminino. A presença de fragilidade foi de 70,5% (IC95% 48,9-87,4), com predomínio feminino (82,4%). A média do tempo no TGlittre foi de 5,77+1,71 minutos. Houve correlação moderada positiva entre TFI e TGlittre (p=0.42, p= 0.03). CONCLUSÃO: Este estudo identificou a fragilidade e comprometimento funcional em idosos com sequela de TB pulmonar, com prevalência alta de fragilidade se comparada aos outros estudos brasileiros com a população idosa, além de apresenta correlação moderada positiva entre a capacidade funcional e fragilidade, mostrando que essa população merece atenção especial nos programas de reabilitação para a manutenção ou recuperação funcional.
