Hyper-Consumerism and Abstract Landscape in Asia
Authors: Geneviève Cyr Marie , Jagos Joseph
Published: August 2020

This project examines the politics of abstract desire, hyper-consumerism, and the notion of fantasy in the Asian and Chinese fashion industries. The fascination for logos is often rooted in nostalgia and is an important part of the visual landscape in popular culture. However, China’s replicas have been labeled as “imitations” or “knock-offs” by Western society. This paper focuses on abstracting the notion of hyper-consumerism and interrogating the relationship between visual advertisement, its materiality, and its representation in the global marketplace. How does advertising contribute to the production of consumer goods? Can we create a cyclical vision for new materials? How is the value of luxury created, displaced, transformed, and consumed via physical space? This project confronts the relevance of luxury and its banalization by proposing new relationships to consumption and examines the visual language of logos and their representation in society.
Selly Raby Kane: Surrealist Designer and Social Innovator
Authors: Picarelli Enrica
Published: August 2020

Selly Raby Kane is a renowned Senegalese fashion designer and artist involved in Africa’s booming art and design movement. Kane is an interesting case study to grasp fashion’s involvement in Africa’s current debate surrounding identity and empowerment through innovation. This article discusses Kane’s designs in light of her contribution not only to contemporary approaches to African fashion that emphasize individuality, but also to effecting change through fashion, examining the ways in which she mixes symbols, signs, and techniques of African and international cultures to inscribe Africa, and Senegal in particular, into the global fashionscape.
Opulent Servitude: Shoplifting in a Culture of Material Excess and Systemic Racism
Authors: Holtz Schramek Evangeline , Kane Carolyn L.
Published: August 2020

Why did the latter part of the nineteenth century witness a sudden growth of white, middle class female shoplifters? Psychology tells us that shoplifting is a mental deficiency manifested in women as “kleptomania” (Abelson 4). Given the subsequent international growth of shoplifting, we argue instead that shoplifting is in many ways condoned in contemporary culture: used as a form of social and political control in a late capitalist society. This article first turns to female consumers as shoplifters in the late nineteenth century, alongside the growth of mass production, large-scale department stores, and visually spectacular forms of display. In line with feminist critiques of Marx’s Capital, we uphold the conditions prescribed to women under capitalism and extend this argument to newer forms of systemic racism in the consumer sphere, which ensure that women of colour and of lower economic standing face even greater obstacles to success.

Using a broad historical view, we analyze the act of shoplifting in two forms of cultural media, both set in Paris. The first is Émile Zola’s novel The Ladies’ Paradise (1883), based on Paris’s first department store, Le Bon Marché. Due to Zola’s commitment to verisimilitude, we argue, his work offers the strongest corroboration of the ways in which new forms of visual display and a new class of psychologically-entitled females worked together to generate astounding accounts of theft. Our analysis then turns to a work of cinema produced nearly a century and a half later, Céline Sciamma’s 2014 Girlhood. Sciamma portrays a group of young French African girls who navigate their paths into adulthood from the vantage of Bagnolet, a lower income immigrant suburb over four kilometers from Paris’s city centre. The girls experience racial profiling and demonstrate varying forms of resistance, one of them shoplifting. While shoplifting then appears to be an enduring weapon of the weak and strategy of resistance by the dispossessed, leading to, not surprisingly, tacitly permissibility for white middle class women and harsher consequences for women of colour, we conclude that the activity is leveraged to perpetuate pre-existent forms of gendered social control and cultural stereotyping.
Grief Becomes Her: Fashion Connections in Daemon & Saudade
Authors: Schindler-Lynch Colleen
Published: August 2020

This essay will present a portion of a body of artwork entitled Daemon & Saudade that was exhibited at the Art Gallery of Northumberland in Cobourg, Ontario from November 15th, 2018, through January 13th, 2019. Photography, fashion, textiles, and jewellery were used in the creation of this interdisciplinary work to explore stories of grief, loss, and the careful crafting of identity. Images and wearable sculptures document time, emotion, and circumstance as they convey personal narratives derived from journaling and sketching. Acrylic and ceramic mourning jewellery show the physical embodiment and beautification of emotion through embellished personal tokens that forever link fashion and grief. The work in Daemon & Saudade demonstrates a role that fashion plays in articulating identity, allowing us to choose what we reveal or conceal and even to mask the experiences and emotions of our daily lives to those closest to us. Collectively, it captures and preserves the marks left on us by the experiences we live. Whether it is the loss of a loved one or a relationship, grief is a condition, a state, an emotion, and a process we all share.
Exhibition Review: Gender Bending Fashion
Authors: Couturier Myriam
Published: August 2020

The Boston Museum of Fine Arts’ recent 2019 exhibition, Gender Bending Fashion, explored some of the ways in which designers and wearers in European and American contexts have challenged traditional ideas around dress and gender over the last century. This included the rejection of conventional dress codes (in the form of men wearing skirts and women wearing suits); the blurring of gender lines in fashion (the combination of “masculine” and “feminine” design elements and the construction of unisex clothing); as well as attempts to transcend the idea of gendered dress altogether (through the creation of new forms of genderless clothing). This review highlights key objects featured in the exhibition, with special attention paid to everyday ensembles and personal narratives that effectively communicated ideas of embodiment, cultural experience, and fashion storytelling that were missing from some of the high fashion garments on display. The deliberately critical and academic approach taken by the curatorial team is discussed, as are some of the tensions and material challenges inherent in representing different bodies and expressions of gender in the context of a major museum fashion exhibition. This exhibition addresses themes that are of critical importance to fashion curators, scholars, and anyone interested in fashion studies more generally.
Analysis of Factors Affecting Yield to Maturity of Corporate Bonds Traded on Indonesia Stock Exchange 2016 - 2018
Authors: Sintami Ayu Asih , Marsoem Bambang Santosoe
Published: August 2020

This study analyzes the influence of the variable Debt Equity Ratio (DER), Maturity, Firm Size and Bond Rating on the Yield To Maturity (YTM) of corporate bonds. The study population consists of corporate bonds traded on the Indonesia Stock Exchange period 2016-2018. The sample selection technique by purposive sampling. The research sample 43 corporate bonds issued by 18 companies from all sectors except the banking and financial sectors. The research analysis method used is descriptive statistics and Common Effect Model (CEM) panel data regression. The results showed that partially the DER variable had no effect on YTM, maturity had a significant positive effect on YTM, Firm Size and Bond Rating significant negative effect on YTM. The implication of this research is that companies need to improve their bond ratings to maintain investor confidence. In addition, is easier for companies with large assets to find external sources of funds through the issuance of bonds. This is because both are proven to have a negative effect on YTM. For further research, is expected to study other variables that affect YTM because the coefficient of determination in this study is 59%, and 41% is influenced by other variables not explained in this study.
The End of Fiduciary Accountability
Authors: Flannigan Robert
Published: August 2020

Some judges and writers have been moving our regulation of opportunism off its conceptual rails. Numerous departures from convention presently are nesting in the jurisprudence and the literature. None of the departures are justified, and all should be purged. They choke the coherent expression of principle. If not dispatched, they may invite or license the collapse of our prudent strict supervision of the mischief that vitally undermines synergy and community.
The Equitable Jurisdiction to Enforce Foreign Judgments
Authors: Lee Stephen
Published: August 2020

There are a variety of instances when courts exercising equitable jurisdiction have recognised and enforced foreign judgments. But when those instances are acknowledged at all, they have tended to be consigned to discrete subject areas and not treated as examples of a wider genus. A new approach is required to keep apace with the needs of an increasingly borderless society. In this article, the author collects in one place the established instances of equitable intervention and argues that they are merely illustrations of a comprehensive equitable jurisdiction to recognise and enforce foreign judgments.
Rule of Law
Authors: Kirby Michael
Published: August 2020

This article, first delivered at The University of Queensland as the Naida Haxton AM Oration 2019, explores some of the components of the rule of law. It starts with building blocks in the common law system, including law reporting for the derivation of precedents. It describes the notable career of Naida Haxton and her approach to law reporting. It then extends to municipal and international law, including that relevant to universal human rights. In that connection, it describes the author’s work as chair of the United Nations Commission of Inquiry on North Korea. It explains its successes and disappointments. Finally, it concludes with the importance of building effective protections for peace and security and justice, including addressing existential challenges such as pandemics, global climate change, and the control of nuclear weapons. The author argues that these components of the rule of law are ultimately integrated and essential to the safety and protection of human beings and the biosphere everywhere.
A Gravitational Redshift Measurement of the White Dwarf Mass–Radius Relation
Authors: Chandra Vedant , Hwang Hsiang-Chih , Zakamska Nadia L. , Cheng 程思 Sihao 浩
Published: August 2020

The mass–radius relation of white dwarfs is largely determined by the equation of state of degenerate electrons, which causes the stellar radius to decrease as mass increases. Here we observationally measure this relation using the gravitational redshift effect, a prediction of general relativity that depends on the ratio between stellar mass and radius. Using observations of over 3000 white dwarfs from the Sloan Digital Sky Survey and the Gaia space observatory, we derive apparent radial velocities from absorption lines, stellar radii from photometry and parallaxes, and surface gravities by fitting atmospheric models to spectra. By averaging the apparent radial velocities of white dwarfs with similar radii and, independently, surface gravities, we cancel out random Doppler shifts and measure the underlying gravitational redshift. Using these results, we empirically measure the white dwarf mass–radius relation across a wide range of stellar masses. Our results are consistent with leading theoretical models, and our methods could be used with future observations to empirically constrain white dwarf core composition and evolution.
Uncovering Magnetic Turbulence in Young Supernova Remnants with Polarized X-Ray Imaging
Authors: Bykov Andrei M. , Uvarov Yury A. , Slane Patrick , Ellison Donald C.
Published: August 2020

Observations of young supernova remnants (SNRs) in X-rays and γ-rays have provided conclusive evidence for particle acceleration to at least TeV energies. Analysis of high-spatial-resolution X-ray maps of young SNRs has indicated that the particle acceleration process is accompanied by strong nonadiabatic amplification of magnetic fields. If Fermi acceleration is the mechanism producing the energetic cosmic rays (CRs), the amplified magnetic field must be turbulent, and CR-driven instabilities are among the most probable mechanisms for converting the shock ram pressure into magnetic turbulence. The development and evolution of strong magnetic turbulence in collisionless plasmas forming SNR shells are complicated phenomena which include the amplification of magnetic modes, anisotropic mode transformations at shocks, as well as the nonlinear physics of turbulent cascades. Polarized X-ray synchrotron radiation from ultrarelativistic electrons accelerated in the SNR shock is produced in a thin layer immediately behind the shock and is not subject to the Faraday depolarization effect. These factors open up possibilities to study some properties of magnetic turbulence, and here we present polarized X-ray synchrotron maps of SNR shells assuming different models of magnetic turbulence cascades. It is shown that different models of anisotropic turbulence can be distinguished by measuring the predominant polarization angle direction. We discuss the detection of these features in Tycho’s SNR with the coming generation of X-ray polarimeters such as the Imaging X-ray Polarimetry Explorer.
Genetic analysis of whole mitochondrial genome of Lateolabrax maculatus (Perciformes: Moronidae) indicates the presence of two populations along the Chinese coast

Published: August 2020

The whole mitochondrial genome ofLateolabrax maculatus(Cuvier, 1828) was used to investigate the reasons for the observed patterns of genetic differentiation among 12 populations in northern and southern China. The haplotype diversity and nucleotide diversity ofL. maculatuswere 0.998 and 0.00169, respectively. Pairwise FSTvalues between populations ranged from 0.001 to 0.429, correlating positively with geographic distance. Genetic structure analysis and haplotype network analysis indicated that these populations were split into two groups, in agreement with geographic segregation and environment. Tajima’s D values, Fu’s Fs tests and Bayesian skyline plot (BSP) indicated that a demographic expansion event may have occurred in the history ofL. maculatus. Through selection pressure analysis, we found evidence of significant negative selection at the ATP6, ND3, Cytb, COX3, COX2 and COX1 genes. In our hypotheses, this study implied that demographic events and selection of local environmental conditions, including temperature, are responsible for population divergence. These findings are a step forward toward the understanding of the genetic basis of differentiation and adaptation, as well as conservation ofL. maculatus.
Cardiorespiratory and Endocrine Mechanisms Behind the Effectiveness of Pranayama
Authors: Ganesan Ramakrishnan Angarai
Published: August 2020

The benefits of pranayama for positive health are well known. Even though there are many studies published on the effectiveness of pranayama, there are very few papers that actually have systematically studied the physiological mechanisms involved, causing the benefits of pranayama, especially with respect to the cardiac function. This chapter attempts to have a detailed look at the physiology behind deep breathing. The chapter also conjectures that voluntary, deep breathing with attention may have a role to play in faster recovery from surgeries and prevent or delay the onset of Alzheimer's disease, Parkinson's disease, and maybe even cancer. Extended, carefully controlled, and detailed studies are needed to prove or disprove these conjectures.
The Yoga of the Bhagavad Gita
Authors: Turci Rubens
Published: August 2020

This chapter explores the fact that śraddhā (truth-force or heart force; love-in-action, self-reliance, faith-in-oneself, and also enthusiasm) may be said to represent the key noticeable outcome of spirituality, yoga, and meditation, and also that śraddhā can be seen as the main category to bridge the gap between science and spirituality. Being itself the truth-force that is common to scientists (atheists or not) and people of different faiths, śraddhā represents a conceptual category that helps us to explain how science evolves shifting from one paradigm to another.
Yoga as a Healing Modality of Trauma-Related Symptoms and Disorders
Authors: Olsen Elin-Kristin Hem
Published: August 2020

Healing after trauma is a long-lasting process involving the body and mind. The neurobiological foundation of trauma calls for more bodily and sensational, bottom-up regulatory approaches. Yoga has been proposed as a possible adjunctive treatment for trauma, and for more complex forms where talk-therapy have been proven insufficient. This chapter will give a theoretical and evidence-based summary of all (to our knowledge) relevant empirical data on yoga as a treatment for trauma-related disorders and symptoms.
Special Yoga for Children and Young People With Special Needs
Authors: Manuel Jyoti Jo
Published: August 2020

Special Yoga has been a provider of therapeutic yoga practices and training since its inception. The non-profit organization started with a yoga center in London, UK. The Special Yoga London center offered a therapeutic and nourishing, nurturing space for families of children with special needs who were welcomed with love, compassion, and totally nonjudgmentally with open arms. The work spread globally through the London-based trainings and the therapeutic yoga that was offered to children at the center and within education. This chapter will discuss my experience and understanding of the efficacy of yoga for children and young people, specifically those with cerebral palsy and autism and/or attention deficit hyperactivity disorder (ADHD). The author shares some of the practices, benefits, and case studies of two separate research studies that were undertaken by Special Yoga for each population. The author also shares other case histories of children that they have worked with.
Yoga as an Intervention for Students With Attention Deficit Hyperactivity Disorder
Authors: Jensen Pauline
Published: August 2020

Research conducted in both the field of yoga and the field of behavioural disorders in children and adolescents leads to the speculation that the benefits of yoga practice demonstrated with respect to physiological, psychological, emotional, and psychosocial functioning may be applicable to the impairments evidenced in these areas in behavioural disorders. The intervention—20 weekly one-hour sessions of yoga—required a large commitment for the participants, their families, and the yoga instructor. The results suggested that yoga appears to exert its impact on stabilising the emotions (a secondary symptom) and reducing oppositional behaviour, frequently co-morbid (40%) with attention deficit hyperactivity disorder (ADHD). Given the limitations of this study, the results do indicate some significant changes in the behaviour of some of the boys with ADHD. In conclusion, yoga shows promise as a non-invasive, inexpensive, adjuvant treatment for boys with ADHD.
Yoga and Polyvagal Theory
Authors: Sullivan Marlysa
Published: August 2020

This chapter explores yoga as a salutogenic intervention supportive of eudaimonic well-being with its wide-spread health effects for various patient populations. Autonomic nervous system regulation and resilience are considered as important meditators for the promotion of biopsychosocial health. Polyvagal theory offers a novel perspective on how underlying neural platforms support combined physiological, psychological, and behavioral states—inclusive of eudaimonic well-being. This chapter describes the convergence of neurophysiological ideas of neuroception, interoception, and neural platforms with yoga foundational concepts such as discriminative wisdom and the gunas. This translatory language of eudaimonic well-being and polyvagal theory offers a framework for yoga to be understood and integrated into current healthcare and research contexts while maintaining its unique perspective and foundational wisdom.
Simulation Tool for Cable Design
Authors: Burstein Leonid
Published: August 2020

This chapter is an updated, enhanced, and expanded paper previously published in IJMMME. An attenuation-based mathematical model and computational tool for communication cable design is presented in the chapter. The relationship derived for the model creation connects attenuation with the following parameters of cable design and testing: copper wire, aluminum and insulation thicknesses, cable impedance, test frequency, and lay length. The expression found from numerous measurement data was used to simulate the Monte Carlo prediction of attenuation in the cable. To realize the simulations, a life script and regular MATLAB script programs were developed. The programs produce a special graphical user interface suitable for non-programmers, cable engineers, and technicians. Results of calculations obtained with the developed tool were verified by experiments and indicate that the tool can be used to design cables with optimal parameters.

Authors: Bosso Nicola , Zampieri Nicolò , Somà Aurelio , Mocera Francesco , Conte Emanuele
Published: August 2020

The chapter shows the study and simulation of a hydropneumatic suspension to be adopted for a telescopic handler vehicle. The hydropneumatic suspension system with independent wheels and with quadrilateral architecture has been studied to improve comfort and productivity of the existing vehicle, which has a suspended rigid axle on the front and a rigid axle on the rear, limiting the comfort and the grip. After the choice of the architecture and the kind of suspension, the chapter shows the design of the suspension kinematics. The optimization of the characteristic angles of the suspension has been performed using Adams/Car and Adams/Insight. The kinematic model optimized is subsequently reproduced in Adams/View to simulate the dynamics of the complete vehicle. Simulation results are used to evaluate vehicle performance in terms of comfort and stability according to the methods proposed by the standards.

Authors: Kharola Ashwani
Published: August 2020

This study considers a fuzzy logic-based reasoning approach for control and optimising performance of overhead gantry crane. The objective of this study is to minimise load swing and to stabilise the crane in the least possible time. The fuzzy controllers were designed using nine Gaussian and triangular shape membership functions. The results clearly confirmed the effect of shape of memberships on performance of fuzzy controllers. Performance of overhead crane was measured in terms of settling time and overshoot ranges. The study also demonstrates the influence of varying mass of the load, mass of crane, and length of crane bar on stability of the crane. A mathematical model of the crane system has been derived to develop a simulink model of proposed system and performing simulations.

Published: August 2020

Syntactic foam is the porous composite produced by mixing prefabricated hollow spherical particle into the matrix. Syntactic foams are used as energy absorption sandwich core for several applications like marine, automotive, and aerospace. In this work, low density hollow glass microspheres are hybridized with fly ash cenosphere in Bisphenol-A epoxy-based vinyl ester matrix. Hybrid syntactic foams is created with 60% total filler content. Within these hybrid systems internal composition of two fillers were varied in a step of 25 vol% with respect to each other. Hybrid syntactic foams are prepared by the hand lay-up (molding) method. The physical characterization parameter contains density and matrix porosity whereas tensile, quasi-static compression, flexural (3-point bending), Izod impact, and micro Vickers hardness are grouped as mechanical characterization parameters. Scanning electron microscopy was performed on fractured surfaces to examine deformation and fracture mechanisms related with each loading condition.

Authors: Amuda Muhammed O. H. , Lawal Taiwo Folorunsho , Mridha Shahjahan
Published: August 2020

To further previous works on grain refinement in ferritic stainless steel (FSS) welds via elemental powder addition, microstructure evolution and mechanical properties in non-metallic carbide treated FSS weld is discussed. Silicon carbide (SiC) powder preplaced on medium chromium FSS bevelled joint was fusion melted using tungsten inert gas (TIG) torch at different combination of process parameters. The incorporation of the powder in the weld pool constricted the weld geometry in addition to grain modification from columnar to equiaxed grain structure. Whilst significant improvement was obtained in hardness characteristics in powder treated welds, those of ductility and tensile strength were marginal. The study also established that welds mechanical properties are controlled by a combination of phenomena such as phase fraction and grain morphology.

Authors: Santos Vanusa Irene Xavier
Published: August 2020

Apesar de Mato Grosso contar, em seu território, com três instituições de Ensino Superior públicas e várias faculdades privadas que realizam ensino, pesquisa e extensão, principalmente sobre o Estado, poucas são as publicações que contextualizam a formação territorial dos municípios mato-grossenses e, quando o fazem, é no contexto geral. O presente artigo tem por objetivo caracterizar a formação territorial do município de Araputanga-MT na visão dos fundadores e não fundadores, assinalando o processo evolutivo que permeia a construção dessa comunidade. Metodologicamente, foram realizadas leituras bibliográficas, investigação de documentos escritos particulares e públicos, entrevistas com os fundadores e não fundadores, explorando o conhecimento dos mesmos em relação à formação territorial do município. Foram entrevistadas 15 pessoas consideradas como “fundadores”, por terem chegado ao município antes de sua emancipação política-administrativa, em 1979, e 29 “não fundadores, que se mudaram para a localidade a partir de 1980. Buscou-se junto aos entrevistados relatos sobre como chegaram ao Município, como era a vivência na comunidade, a saúde, a educação, a economia que predominava no período, assim como ocorreu o processo de formação política dessa cidade, a origem dos primeiros habitantes, os principais festejos, moradias que mais se destacavam na época e como era a vegetação no período de sua chegada. Como resultados, foi possível analisar as mudanças socioespaciais ocorridas no Município durante o período em estudo.

Published: August 2020

As praias são sistemas ambientais altamente dinâmicos e ao mesmo tempo sensíveis que sofrem transformações em várias escalas espaciais e temporais por fatores relacionados a dinâmica natural e outros relacionados a intervenções antrópicas na zona costeira. Na praia do Balbino, localizada no município de Cascavel, no litoral leste do Estado do Ceará, a erosão costeira se intensificou nos últimos anos, reduzindo a faixa de praia, destruindo barracas e outras estruturas costeiras, gerando prejuízos sociais e ambientais. Este trabalho teve como objetivo caracterizar os processos erosivos e deposicionais na área. Foram realizados perfis topográficos bimestrais no período de setembro/2016 a setembro/2017; coleta de sedimentos nos setores de pós-praia, estirâncio e antepraia e aquisição de dados hidrodinâmicos. Em laboratório foi realizada a análise granulométrica dos sedimentos. A atuação mais intensa dos ventos nos meses de setembro/2016 e setembro/2017, contribuíram para os registros mais altos de altura significativa, energia e velocidade do grupo de ondas, além dos maiores volumes de sedimentos transportados. Os perfis P1, P3 e P4 apresentaram um balanço sedimentar negativo, nos demais perfis (P2, P5, P6 E P7) o balanço foi positivo. As características sedimentares indicam uma praia composta predominantemente por areia média, de moderada a bem selecionada, mesocúrticas e aproximadamente simétricas. A erosão costeira verificada na área é relacionada a dinâmica costeira, principalmente aos períodos de ventos mais intensos e marés de maior amplitude, o impacto é mais significativo onde há presença de ocupações em setores de transpasse sedimentar como na faixa de praia e dunas frontais.

Published: August 2020

Nanosized La0.75K0.05Ba0.05Sr0.15MnO3 manganite have been synthesized using sol-gel method. Afterwards, the samples were sintered at eight different temperature ranging from 650 to 1000 °C. Phase purity, crystal structure and the morphology of the sample have been examined using X-Ray Diffractometer (XRD) and Scanning Electron Microscope. It has been found that different higher sintering temperature greatly affect the phase purity and crystallite size of the sample. Regardless of the sintering temperature, all the samples crystallized in rhombohedral structure with R-3c space group. The crystallite size of the samples is found to increase from 41.59 nm up to 73.42 nm as the sintering temperature increases. Further analysis from XRD result shows that sintering temperature also affect the average Mn-O bond length and Mn-O-Mn bond angle of the sample. The average Mn-O bond length is found to increase while the average Mn-O-Mn bond angle tends to decrease as sintering temperature increases. SEM measurement shows that various grain size ranging from ~100 nm up to ~ 350 nm exists in all the sample regardless the sintering temperature.

Published: August 2020

Effect of difference silica source, namely commersial silica and silica from rice husk, as Si precursor on the synthesis of lanthanum silicate apatite (LSO) have been investigated. The conductivity of LSO was determined by impedance spectroscopy using LCR meter. The conductivity of LSO based on rice husk extraction (s700°C = 2.13 ´ 10-4 S.cm-1) was ten times lower than that of LSO with commercial silica (s700°C = 3.11´ 10-5 S.cm-1). Carbon content as an impurity on silica from rice husk extraction is suspected to decrease the homogeneity of its morphology so that it has an impact on its conductivity.

Published: August 2020

Magnesium alloy has been widely investigated as a biodegradable implant material owing to its unique properties to degrade spontaneously in human body fluid without causing toxicity. However, the degradation rate needs to be controlled. An effective way to lower down the degradation rate of Mg alloy is by coating with plasma electrolytic oxidation (PEO) technique. In this research, the microstructure and mechanical hardness of the PEO film formed on AZ31 were investigated. The film was prepared under a constant current of 400 A/m2 in the Na3PO4 solution at 30°C. The voltage-time curve showed an immediate increase of current during the first 25 s before reaching a steady-state voltage of 150 V. The spark discharge revealed as white micro discharges. The film formed for 3 min exhibited a high surface roughness with a large variety of thickness in the range of 1-20 µm. The film contained pores and cracks. The big pores with diameter size 10-20 µm were formed as a result of gas entrapment, while the small pores with a radius of 1-3 µm were associated with the discharge tunnel during the PEO process. The X-ray diffraction pattern indicated that the film composed of crystalline Mg3(PO4)2.

Since the discovery of hexagonal ferrite or known as hexaferrites, research into the development of these materials related to commercial fields and technology has been very rapid. The use of hexaferite as a magnetic material that can be mass produced has a wide application field. Therefore, the magnetic properties of hexaferrites should be adjusted to meet these applications requirements. In this respect, cation substitution is one of the most effective ways to obtain a suitable material. Double layer coating design with variations in thickness of 1 mm, 2 mm, 3 mm, and 4 mm on Radar Absorbent Material (RAM), with Barium M-Hexaferrite (BaM) BaFe12-xZn xO19 as magnetic material with variations in doping concentration of Zn2+ ions x = 0, 0.3 and 0.9 have been successfully synthesized by the solid state reaction method. Likewise with Polyaniline (PANi) with Dodecylbenzene Sulfonic Acid (DBSA) dopant as a conductive material, it have been successfully synthesized by the polymerization method. Radar absorbing materials (RAM) are characterized using X-Ray Diffraction (XRD), Four Point Probes (FPP), Fourier Transform Infrared (FTIR), Vector Network Analyzer (VNA), and Scanning Electron Microscope (SEM). The results of XRD characterization showed that the largest primary phase was obtained at BaM x= 0.9 which was 96.56%. The increassing of concentration dopping of Zn2+ ions to influence of decreasing the magnetic dipole of magnetic materials and the magnetic properties be come softmagnet materials. The variations in thickness coating radar absorbing materials the influence of absorption of electromagnetic waves occurs optimally, and the increase of thickness coating have coused the value of loss of reflection and widening of the absorption band of the X-Band range (8-12 GHz) increasing. The highest reflection loss and widening of the absorption band value is obtained from coating BaM x = 0.9 with a thickness of 4 mm, which are respectively - 16.29 dB, and 3.78 GHz. So that it can be concluded that the addition of the doping concentration of Zn2+ ions and the dimensions of the layer thickness can increase the absorption ability of RAM material.

We have studied the effect of lead (II) cyanate Pb (OCN)2 additive on photovoltaic properties of inverted planar solar cells based on inorganic-organic hybrid perovskite CH3NH3PbI3. The active layers of the solar cells were fabricated with a reaction between CH3NH3I and a mixture of PbI2 and Pb (OCN)2. The highest power conversion efficiency was 15%. Hysteresis behaviors in JV curves were reduced. The lifetime of the solar cells was dramatically increased. SEM images indicated that crystallite sizes were enlarged. The OCN groups were not incorporated into crystals from infrared measurements. These results suggest that Pb (OCN)2 affect mainly the crystallization process of CH3NH3PbI3.

We attempt to study the effect of gold nanoparticles embedded into the active polymer of regioreguler poly (3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) on the charge kinetic to enhance the performance of bulk-heterojunction solar cell. It has been known that the generation of localized surface plasmon resonance (LSPR) would both increase the photon absorption and improve the efficiency of charge separation. Synthesis of gold nanoparticles stabilized by oleylamine (AuOA) was carried out by reduction method and resulted in the spherical shape of nanoparticles with a diameter size of ~12 nm. The absorbance spectra show the typical of surface plasmon peak of AuOA in solution at ~527 nm. Fabrication of inverted bulk-heterojunction solar cell device was done in the configuration of ITO/ZnO/P3HT:PCBM:AuOA/PEDOT:PSS/Ag. Incorporation of AuOA in polymer solution is clearly detected from the enhanced absorbance peak resulted from UV-Vis measurement and the mix solution of P3HT:PCBM:AuOA is quite stable in the concentration of AuOA less than 10 wt%. In our experiment, fabricated solar cell reveals the enhancement in current density at short circuit condition (Jsc) from 44.57 mA/cm2 to 56.14 mA/cm2 with the addition of 3.9 wt% AuOA in polymer solution along with the enhancement of power conversion efficiency (PCE) from 4.07% to 6.23% as characterized by J-V measurement. In our case, the voltage at open circuit condition (Voc) of the device does not show significant improvement.

Banana (Musa acuminate) is one of the important fruit crop cultivated in Indonesia. Banana stems is waste biomass form banana farming which the amount is very abundant. Recently, the banana stems waste was used for animal feed, but the amount is small, mostly goes as waste. Banana stems have a high cellulose and hemicellulose content, more than 60%, which made it useful for row material of Carboxymethyl Cellulose (CMC). In this paper, we synthesized CMC from banana stems and apply it as binder in the electrodes of lithium ion battery. The steps of synthesizing CMC from banana stems started with the isolation of the cellulose, then followed by the processes of alkalization, carboxymethylation and finally the purification. FTIR spectrum shows the absorption bands at 3427 cm-1, 2928 cm-1, 1613 cm-1 and 1420 cm-1 which indicated the successfully of CMC synthesized. The presence of strong absorption bands at 1613 cm-1 and 1420 cm-1 are related to the stretching vibration of the carboxyl group (COO-) and (COO-Na). The peak absorption at around 2928 cm-1 is due to stretching vibration of all hydrocarbon constituent in CMC. While the broad absorption around 3427 cm-1 is due to the stretching vibration of the hydroxyl groups (-OH). The purity test of CMC mesh-100 is resulting the purity values of 99.84%. These results prove that CMS has actually been formed with high purity. In the application of CMC as anode binder, the best composition is 3 % CMC, where it gives the highest conductivity of 0.457 S/cm. Voltammogram cyclic measurement with a scan rate of 50 mV/s in the voltage range of -1.2 to 1.2 Volt gives the capacitance value of 18 mF.

Magnetic nanofluids are a category of nanomaterial which exhibit simultaneously liquid and superparamagnetic properties. These nanofluids are magnetic nanoparticles stably dispersed in liquid carrier. Magnetic nanoparticles with and without SiO2 encapsulation have been successfully synthesized by co-precipitation method from ferrous and ferric precursors dispersed in various liquid. Fe3O4 nanoparticles were investigated by Zeta Potential and HR-TEM to determine the stability of nanoparticles, average particles size and microstructure of nanoparticles. From zeta potential measurements, is was found that the value of zeta potential for Fe3O4 dispersed in ethanol was ± 0,9 mV, while dispersed in di-water was ± 31,1 mV, indicating that nanoparticles Fe3O4 are more stable in DI-water. The increasing of zeta potential indicated the adsorption of negatively charged hydroxyl group to the surface of Fe3O4 nanoparticles. From XRD measurements, it was found that crystal quality of Fe3O4.SiO2 sintering at 80 °C decreased by increasing the volume of tetraethyl orthosilicate (TEOS), while that samples sintering at 1000 °C have a good crystal quality with hexagonal phase of a-Fe2O3.SiO2. From SQUID measurements, it was found that samples of Fe3O4.SiO2 sintering at 80 °C with TEOS volumes of 1 ml and 2 ml showed a paramagnetic like while samples of a-Fe2O3.SiO2 sintering at 1000 °C with the same TEOS volume showed ferrimagnetic properties.

Ischemia–reperfusion injury (IRI) is a complex inflammatory process that detrimentally affects the function of transplanted organs. Neutrophils are important contributors to the pathogenesis of renal IRI. Signaling by G-CSF, a regulator of neutrophil development, trafficking, and function, plays a key role in several neutrophil-associated inflammatory disease models. In this study, we investigated whether targeting neutrophils with a neutralizing mAb to G-CSFR would reduce inflammation and protect against injury in a mouse model of warm renal IRI. Mice were treated with anti–G-CSFR 24 h prior to 22-min unilateral renal ischemia. Renal function and histology, complement activation, and expression of kidney injury markers, and inflammatory mediators were assessed 24 h after reperfusion. Treatment with anti–G-CSFR protected against renal IRI in a dose-dependent manner, significantly reducing serum creatinine and urea, tubular injury, neutrophil and macrophage infiltration, and complement activation (plasma C5a) and deposition (tissue C9). Renal expression of several proinflammatory genes (CXCL1/KC, CXCL2/MIP-2, MCP-1/CCL2, CXCR2, IL-6, ICAM-1, P-selectin, and C5aR) was suppressed by anti–G-CSFR, as was the level of circulating P-selectin and ICAM-1. Neutrophils in anti–G-CSFR–treated mice displayed lower levels of the chemokine receptor CXCR2, consistent with a reduced ability to traffic to inflammatory sites. Furthermore, whole transcriptome analysis using RNA sequencing showed that gene expression changes in IRI kidneys after anti–G-CSFR treatment were indistinguishable from sham-operated kidneys without IRI. Hence, anti–G-CSFR treatment prevented the development of IRI in the kidneys. Our results suggest G-CSFR blockade as a promising therapeutic approach to attenuate renal IRI.
