Authors: Heo Min , Lee Min Sik , Seo Hyung Yoon , Kang Chung Gil
Published: June 2020

Recently, automobile components such as center pillars and impact beams have been fabricated using materials that satisfy both high strength and impact absorption. In this study, the forming process of CR340 (cold rolled steel)/CFRP hybrid composites was investigated. Initially, hybrid composites were fabricated by stacking carbon fibre reinforced plastic (CFRP) prepreg on CR340 steel with Zn coating. An adhesive agent developed by the research team was applied for bonding between the cold rolled steel and CFRP to enable the blank fabrication of hybrid composites. The mechanical properties of the developed hybrid composites were investigated by tensile, bending and lap shear adhesion test. The results showed that the tensile strength and shear strength of composites increases with the increase in the number of laminations but the bending strength decreases.
Assessment of Silicone Rubber Properties Using Dynamic Modelling Simulation
Authors: Sharudin Rahida Wati , Nik Salwani Md Azmi
Published: June 2020

The investigation of silicone rubber properties with the presence of platinum catalyst at different temperature using molecular dynamic simulation was conducted. Visual observation shows that structuring of silicone rubber occurs in the cell where the molecules aggregates closer compared to at the beginning of the simulation and at higher platinum concentration, silicone rubber molecules are more closely packed together. The diffusion coefficient of silicone rubber are the highest in a 10% platinum concentration followed by 25% and lastly 50% indicating that it is harder for the silicone rubber molecules to move from its original position in the system as the platinum concentration increases. Structural changes was also investigated through radial distribution function (RDF) where the position of peaks did not change with time but there is changes observed in the intensity of the peak. At a constant temperature 50°C, it was observed that the intensity of the peak at 1.10Å radius was the highest in the presence of 50%Pt followed by 25%Pt and 10%Pt. This indicates that higher numbers of silicone rubber molecules are present in a 1.10Å radius from the reference molecules in a system with higher concentration of platinum.

Authors: Yan Wen Duan , Fu Gao Sheng , Zhou Xiu Min , Chen Dong Dong
Published: June 2020

Grain characteristics of rolled 1235 aluminum alloy were studied by EBSD. The effects of hot rolling, cold rolling and rolling deformation on grain boundaries and grain size of the metal were studied as well. The content of high-angle boundaries was low by 16.48 % in 50 % hot-rolled 1235 aluminum alloy. The complete dynamic recrystallization occurred, and grains were coarse. During 90 % hot rolling, the low-angle boundaries turned into high-angle boundaries constantly. The content of high-angle boundaries was higher by 40.16 %. Coarse grains broke into fine grains, and grew into medium grains. In the 90 % cold-rolled alloy, the trace shape of high-angle boundary was irregular. The lattice distortion was large, providing the energy needed in recrystallization during recrystallization annealing.

Authors: Loucif Abdelhalim , Zhang Chunping , Jahazi Mohammad , Lapierre-Boire Louis Philippe
Published: June 2020

In the present work, the segregation degrees of ferrite and austenite stabilizer alloying elements were analyzed for a high strength steel. For this, samples were taken from the surface and center of the hot-top and the upper section of a 40 MT ingot. The results showed that the positive segregation ratios for all the investigated elements were higher in the ingot center than in the surface with higher values for austenite stabilizer elements. The increase of austenite alloying element stabilizers was accompanied by the change in the primary solidification mode of the austenite phase. The obtained results are in good agreement with the observed presence of austenite, revealed by X-ray diffraction analysis, stabilized by the austenite alloying elements.

Authors: Khalaj Omid , Saebnoori Ehsan , Jirková Hana , Chocholaty Ondrej , Svoboda Jiří
Published: June 2020

The Oxide Precipitation Hardened (OPH) steel is a new developed group of materials from Oxide Dispersion Strengthened (ODS) alloys which are well known advanced materials for high temperature properties. Besides, the corrosion resistance of these types of material is so important regarding to their practical usage. The production of OPH alloys, the same as ODS alloys, involves mechanical alloying process to create material with ductile matrix and hard oxide dispersion. Six variants of Fe-Al base OPH steel which developed and manufactured by the authors, were prepared with different chemical composition to evaluate the role of main component on the mechanical properties and corrosion resistance of new-developed OPH steels. The corrosion tests were done using potentiodynamic polarization methods. The results show that the Aluminum content has a main role both on mechanical properties and corrosion resistance.
Experimental Study on Concrete-Filled Double Skin Circular Steel Tubular Beams under Bending Load
Authors: Lee Seung Jo , Park Jung Min
Published: June 2020

This paper examines the structural and mechanical behavior characteristics of the concrete-filled double circular steel tube (CFDT) fabricated with the installation of shape memory alloys (SMAs) and reinforcement bars in the inner and outer steel tubes, the inner-outer diameter ratio (Di/Do), and the concrete strength as the main variables. Towards this end, the displacement ductility, crack patterns, load-central deflection relationship, displacement ductility, and flexural shear strength were compared and analyzed. The results verified that a change in the Di/Do has significant effects on the crack pattern, maximum load, and ductility. The specimens with SMAs installed between the inner and outer steel tubes generally showed good results.

Published: June 2020

The advantages of supplementary cementitious materials (SCM) use in concrete, such as reduced cement consumption and overall material improvement (durability, chemical resistance, etc.), are widely known. Our research focuses on two major factors connected to high performance concrete (HPC) containing SCM, the content of selected SCM and the homogenization process used for concrete mixture. Both of these aspects of this research were addressed by the authors from macro-level of the material. In this contribution, the focus is directed on microscopical performance of concrete mixtures with highest macro-mechanical features with respect to both homogenization procedure and SCM containment.

Published: June 2020

The present investigation intended to analyse the mechanical properties of medium carbon low alloy steel (AISI 4140) under dual phase heat treatment condition. Formation of dual phase, ferrite and martensite (F+M) from normalized condition followed by heating in the intercritical temperature range to form different volume fractions of ferrite and martensite alters tensile, hardness and impact strength of medium carbon steel. Effect of alloying elements in dual phase treatment will change the mechanical properties. Tensile strength and hardness of austempered steel shows higher value followed by dual phase condition. Ductility of normalized shows better as compared to as bought and dual phase, but austempered shows almost similar to normalized result. Impact strength of the austempered is excellent followed by dual phase condition. Heat treated specimen microstructures reveal the different phase’s present.
Towards Reducing Computational Costs of Finite Difference Time Domain Algorithm in Plasmonic Optical Properties Modelling of Metal Nanoparticles
Authors: Rafiee Mehran , Ahmed Hind , Chandra Subhash , Mc Loughlin Conor , Glenn Aaron , McCormack Sarah
Published: June 2020

Finite difference time domain (FDTD) method is a grid-based, robust and straightforward method to model and study the optical properties of metal nanoparticles (MNPs). However, high computational costs of FDTD including simulation time and memory demand mitigate the interest in this algorithm. In this paper, FDTD algorithm is reviewed and reasons of high computational cost requirement in FDTD are investigated. Computational costs are directly characterised by the resolution and size of FDTD grid (known as Yee grid). High FDTD grid resolution is essentially required in MNPs plasmonic modelling to achieve promising accuracy. This results in increasing the dimension of FDTD operational parameters (stored in FDTD matrices) which increases memory and simulation time required and consumed by the algorithm.

Indigenous way of hyperthermic intraperitoneal chemotherapy
Authors: Dutta Rishin , Das Soumen , Saha Makhan Lal
Published: June 2020

Introduction: Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a form of highly concentrated, heated chemotherapy that is delivered directly to the abdomen intra-operatively. Currently for peritoneal surface malignancy (PSM), either primary or secondary from gastrointestinal (GI) or gynecologic cancers, cytoreductive surgery (CRS) combined with peri-operative HIPEC therapy is recommended. Aims & objectives: The primary objective of this case report is to show that in the current era of malignancy, resource poor centers can adopt our innovative way of HIPEC therapy and can treat peritoneal neoplasms which were considered to have only palliative treatment. Methods: After proper pre-operative work up, 61 year old lady diagnosed with adenocarcinoma of the sigmoid colon with peritoneal deposits was taken up for cytoreductive surgery and HIPEC. In the absence of a proper HIPEC machine, we used the hotline fluid warmer used by Anesthesiologists to heat the chemotherapy solution which was then re-circulated manually. Results: The patient had an excellent post-operative recovery and was discharged in a hemodynamically stable condition on post-operative day (POD) 6. She has completed 18 months of follow-up and has no signs of recurrence. Conclusions: To treat cancer like peritoneal neoplasm in resource-poor centers, the hotline machine can be a good option.
Nanosatellites applied to optical Earth observation: a review
Authors: Nagel Gustavo Willy , Novo Evlyn Márcia Leão de Moraes , Kampel Milton
Published: June 2020

Nanosatellites and CubeSats were first developed for educational purposes. However, their low cost and short development cycle made nanosatellite constellations an affordable option for observing the Earth by remote sensing, increasing the frequency of high-resolution imagery, which is fundamental for studying and monitoring dynamic processes. In this sense, although still incipient, nanosatellite applications and proposed Earth observation missions are steadily growing in number and scientific fields. There are several initiatives from universities, space agencies and private companies to launch new nanosatellite missions. These initiatives are actively investigating new technologies to improve image quality and studying ways to increase acquisition frequency through the launch of larger constellations. So far, the private sector is leading the development of new missions, with proposals ranging from 12 to more than one thousand nanosatellite constellations. Furthermore, new nanosatellite missions have been proposed to tackle specific applications, such as natural disasters, or to test improvements on nanosatellite spatial, temporal and radiometric resolution. The unprecedented combination of high spatial and temporal resolution from nanosatellite constellations associated with improvement efforts in sensor quality is promising and may represent a trend to replace the era of large satellites for smaller and cheaper nanosatellites. This article first reports on the development and new nanosatellite missions of space agencies, universities and private companies. Then a systematic review of published articles using the most successful private constellation (PlanetScope and Doves) is presented and the principal papers are discussed.

Nonlinear Hyperbolic Problems: Modeling, Analysis, and Numerics
Authors: Colombo Rinaldo M. , LeFloch Philippe G. , Rohde Christian , Trivisa Konstantina
Published: June 2020

The workshop gathered together leading international experts, as well as most promising young researchers, working on the modelling, the mathematical analysis, and the numerical methods for nonlinear hyperbolic partial differential equations (PDEs). The meeting focussed on addressing outstanding issues and identifying promising new directions in all three fields, i.e. modelling, analysis, and numerical discretization. Key questions settled around the lack of well-posedness theories for multidimensional systems of conservation laws and the use of hyperbolic modelling beyond the classical topic of gas dynamics. A focal point in numerics has been the discretization of random evolutions and uncertainty quantification. Equally important, new multi-scale methods and schemes for asymptotic regimes have been considered.

Depremler sırasında oluşan ve ivmeölçerler tarafından geçici ya da kalıcı istasyonlarda ölçülmekte olan kuvvetli yer hareketleri, temel olarak, kaydedilen depremin büyüklüğüne, kaynaktan istasyona olan mesafeye ve istasyonun bulunduğu (yerel) zemin özelliklerine bağlı olarak değişirler. Bu ivme-zaman kayıtları, yer bilimlerinden deprem mühendisliğine uzanan farklı disiplinlerde kullanılmakta olan girdi parametreleridir. Dünyada ve ülkemizde bulunan kuvvetli yer hareketi ağları sürekli olarak genişlemekte; bu sayede farklı deprem kayıtları ile hem geçmiş depremlere ait kaynak bilgileri hem de yerküre hakkındaki çalışmalar sayıca artmaktadır. Ancak, farklı büyüklükteki depremler istatistik olarak aynı sıklıkta meydana gelmediği için, dünyanın en gelişmiş ağlarında bile kayıt eksiklikleri bulunmaktadır. Başka bir deyişle, bir bölgede olası sismik etkilerin bütünü incelenmek istendiğinde bazı şiddet değerlerine karşılık gelen kayıtlar bulunmamaktadır. Yoğun istasyon dağılımı bulunmayan yer hareketi ağlarında ise bu sorun daha belirgin olarak ortaya çıkmaktadır. Bu sebepler nedeniyle günümüzde yer hareketi benzetim çalışmaları tüm dünyada giderek önem kazanmaktadır. Çalışmanın temel amacı; Türkiye’deki en aktif fay hattı olan Kuzey Anadolu Fay Hattı üzerinde olası depremler için benzeştirilmiş bir yer hareketi veri tabanı hazırlamak, bunun temel özelliklerini incelemek ve bu özellikleri gerçek yer hareketlerinden elde edilmiş bulgular ile karşılaştırmaktır.

Perder el sýmbolon. A propósito de un allanamiento
Authors: Moreno Tirado Guillermo
Published: June 2020

En este trabajo se analiza el apartado “a” del parágrafo 72 del curso de Heidegger Los conceptos fundamentales de la metafísica. Mundo, finitud, soledad de 1929-30, interpretando que la lectura de Heidegger del problema del “suceder símbolo” en Aristóteles puede ser un recurso para exponer en qué sentido nuestro punto de partida para la reflexión sobre el lenguaje tiene que ser el de la lingüística, a pesar de que esta reflexión termine mostrando que esta ciencia no puede constituirse como fundamento último del problema del lenguaje. A tal circunstancia la llamamos “perder el sýmbolon” por cuanto nuestro punto de partida presupone que no hay “secuencias lingüísticas” marcadas de antemano, siendo justamente esa marca lo que indica el “suceder símbolo”. Este trabajo interpreta, a modo de conclusión, que el problema del lenguaje se nos presenta como un fenómeno de allanamiento simbólico.
An Evaluation of Karl Barth’s Encounter Revelation and the View of God
Authors: Mwita Alexander
Published: June 2020

This paper aimed at evaluating Karl Barth’s theology of encounter revelation and the view of God in relation to the Christian theology of the knowledge of God. It employed literary approach of research that involves bibliographic data in four sections. The first section discussed a brief history of Karl Barth. The second section is an overview of the doctrine of revelation, both general and special revelation. Section three discussed Karl Birth’s view of God in the context of encounter revelation. The fourth section evaluated Karl Barth’s view of encounter revelation in relation to the knowledge of God. This study concluded that the encounter revelation is not the only way of knowing God. Though God reveals Himself fully through the person of Jesus Christ, He also reveals Himself in through general (Universal) and special (particular) revelation.
Scaling up Grounded Theory: Problems, Implications and Options for Qualitative Researchers
Authors: Sigauke Innocent , Swansi Kenneth , Tsvara Peter
Published: June 2020

The purpose of the grounded theory method is to develop a theory. While some grounded theories generated through the method have limited application because they tend to be grounded in the data of a single substantive area, if a substantive grounded theory is scaled up, it can be applied to more areas besides the substantive area from which it is derived. Therefore this paper outlines the options in scaling up a substantive grounded theory study.

The Possibility of Critique in an Era ruled by the Media
Authors: Vuksanović Divna , Ćalović Dragan
Published: June 2020

Taking the philosophy of media as a starting point, this text examines the possibilities, forms and status of critique in our times which are dominated, at least in the West, by what is known as media culture. On the one hand, the text avoids reducing systemic and strategic critique of capitalism to merely a critical point of view, while on the other it problematizes and examines the critique of modern media practices. The authors implicitly conclude that merely asking these questions paves the road to comprehensive critical action, within the existing systems of this media universe, as well as beyond it, i.e. in the particular socio-economic system of thought and action. This text also examines the possibility of achieving critical practices through art, and in the context of emerging new technologies. Possibilities for critique within the framework of new media art are explored in particular, as this might revolutionize not only media practices, but also the social, historical and economical practices of capitalism as such.
Philosophy and Consciousness in the Future
Authors: Vertovšek Nenad , Greguric Knežević Ivana
Published: June 2020

Natural sciences and technologies place artificial intelligence, robotics and cyborgs at the centre of human attention. However, virtual and augmented reality and the unthinkable possibilities of the future media and communication between individuals and social groups might be deeper and broader than we think, and evolve in forms we have not hoped for. If philosophy wants to focus on the essence of scientific-technical age, it must reflect on the very foundations of computer-operational thinking, because artificial intelligence has already started to develop its own consciousness and may, in the future, devise a strategy of development beyond man and without man.

O ensino da ginástica na escola: um relato de experiência com a pedagogia histórico-crítica
Authors: Viana Ludmila Siqueira Mota
Published: June 2020

O presente texto é um relato de experiência, resultante de uma prática pedagógica sistematizada da educação física escolar, eixo temático Ginástica, em uma escola conveniada da Secretaria Estadual de Educação (SEDUC) de Goiás. Para a construção e desenvolvimento da nossa proposta tomamos como referencial a pedagogia histórico-crítica e a perspectiva crítico-superadora da Educação Física. Destacamos as possibilidades e desafios do conteúdo Ginástica na prática pedagógica da Educação Física Escolar desenvolvida com alunos do 9º ano do Ensino Fundamental II, na qual o Festival de Ginástica se apresentou como uma possibilidade relevante para se trabalhar a ginástica nas aulas de Educação Física na escola. Podemos concluir que a ginástica proporcionou aprendizagens significativas para os alunos e esperamos que esta experiência possa auxiliar os professores a refletirem sobre este tema na escola.
Inclusão de alunos com deficiência nas aulas de Educação Física em escolas públicas regulares do Brasil: uma revisão sistemática de literatura
Authors: Castro Mariana Oliveira Rabelo de , Telles Silvio De Cassio Costa
Published: June 2020

A legislação brasileira propõe a inserção de alunos com deficiência em escolas regulares. Desta forma, o objetivo do artigo foi identificar, através de uma revisão sistemática, como se dá o processo inclusivo destes alunos nas aulas de Educação Física, em escolas públicas regulares brasileiras. Metodologicamente, a pesquisa foi realizada em quatro bases de dados (Lilacs, Scielo, Portal Regional da BVS e Portal de Periódicos da Capes) seguindo as orientações PRISMA. Os resultados foram classificados em três categorias, por meio da análise de conteúdo. Percebemos que os professores e a comunidade escolar enfrentam dificuldades relacionadas à precária formação docente, à pouca interação interpessoal e à mínima acessibilidade arquitetônica, instrumental e metodológica. Concluiu-se que o processo inclusivo, apesar dos empasses, se encontra em desenvolvimento.

The outbreak of the COVID-19 pandemic has weakened the macroeconomic outlook. The authorities have launched a health care contingency plan and an initial package of economic measures, together totaling $31 million (0.4 percent of GDP), and are preparing a second, larger package of economic measures of about $400 million (5.2 percent of GDP). To help address an urgent balance of payments need arising from the pandemic, estimated at about $500 million, the authorities request an additional purchase under the Rapid Financing Instrument (RFI) of 33.3 percent of quota (SDR 59.2 million) and a disbursement under the Rapid Credit Facility (RCF) of 16.7 percent of quota (SDR 29.6 million) under the “exogenous shock” window of the RCF. This follows Board approval on March 26, 2020 of the authorities’ earlier request for the same amounts, before the doubling of the annual access on emergency financing under the “exogenous shock” window of the Rapid Credit Facility (RCF) to 100 percent of quota was approved on April 6, 2020. This additional request will bring the total purchases under the RFI and the disbursements under the RCF to 100 percent of quota in 2020.

The BCCh is considering broadening access to its services beyond commercial banks
and some Financial Market Infrastructures (FMIs). The services include settlement
accounts, intra-day liquidity, standing deposit and lending facilities, and eligibility for ELA.
Banks have always had access to these services, while Central Counterparties (CCPs) and the
Securities Settlement System (SSS) were granted access to a settlement account in 2009. The
BCCh is considering extending its services to various types of Nonbank Financial Institutions
(NBFIs) to enable it to more closely manage and mitigate financial stability risks.

Ensemble daily simulations for elucidating cloud–aerosol interactions under a large spread of realistic environmental conditions
Authors: Dagan Guy , Stier Philip
Published: June 2020

Abstract. Aerosol effects on cloud properties and the atmospheric energy and radiation
budgets are studied through ensemble simulations over two month-long periods
during the NARVAL campaigns (Next-generation Aircraft Remote-Sensing for
Validation Studies, December 2013 and August 2016). For each day,
two simulations are conducted with low and high cloud droplet number
concentrations (CDNCs), representing low and high aerosol concentrations,
respectively. This large data set, which is based on a large spread of
co-varying realistic initial conditions, enables robust identification of
the effect of CDNC changes on cloud properties. We show that increases in
CDNC drive a reduction in the top-of-atmosphere (TOA) net shortwave flux
(more reflection) and a decrease in the lower-tropospheric stability for all
cases examined, while the TOA longwave flux and the liquid and ice water
path changes are generally positive. However, changes in cloud fraction or
precipitation, that could appear significant for a given day, are not as
robustly affected, and, at least for the summer month, are not statistically
distinguishable from zero. These results highlight the need for using a large
sample of initial conditions for cloud–aerosol studies for identifying
the significance of the response. In addition, we demonstrate the dependence
of the aerosol effects on the season, as it is shown that the TOA net
radiative effect is doubled during the winter month as compared to the
summer month. By separating the simulations into different dominant cloud
regimes, we show that the difference between the different months emerges due
to the compensation of the longwave effect induced by an increase in ice
content as compared to the shortwave effect of the liquid clouds. The CDNC
effect on the longwave flux is stronger in the summer as the clouds are deeper
and the atmosphere is more unstable.
