Authors: Pamungkas Rio , Puspitasari Ratih
Published: February 2020

Kebijakan manajemen keuangan jangka panjang merupakan kebijakan yang berhubungan dengan modal perusahaan. Pendanaan perusahaan dapat berasal dari hutang atau ekuitas yang dimiliki perusahaan. Ekuitas perusahaan dapat berasal dari modal sendiri dan modal pemegang saham atau obligasi.

Tujuan dari penelitian ini yaitu untuk mengetahui kebijakan keuangan jangka panjang pada PT Ciputra Development TBK untuk mengetahui sumber modal yang di gunakan oleh perusahaan; untuk mengetahui kinerja keuangan jangka panjang perusahaan.

Hasil penelitian ini menunjukan bahwa perusahaan lebih dominan menggunakan ekuitas dari pada hutang untuk keperluan modal perusahaan. Hal tersebut ditunjukan oleh rasio DAR yang rata – rata selama 5 tahun hanya mencapai 32,2% artinya modal perusahaan yang dibiayai dengan hutang hanya 32,2% baik hutang jangka panjang dan hutang jangka pendek. Sedangkan rasio DER 67,8% artinya modal perusahaan yang didanai oleh ekuitas sendiri dan dana dari pemegang saham PT Ciputra Development Tbk lebih besar persentasinya dari modal yang memanfaatkan hutang jangka panjang atau jangka pendek

Simulating Turbulence-aided Neutrino-driven Core-collapse Supernova Explosions in One Dimension
Authors: Couch Sean M. , Warren MacKenzie L. , O’Connor Evan P.
Published: February 2020

The core-collapse supernova (CCSN) mechanism is fundamentally 3D, with instabilities, convection, and turbulence playing crucial roles in aiding neutrino-driven explosions. Simulations of CCNSe including accurate treatments of neutrino transport and sufficient resolution to capture key instabilities remain among the most expensive numerical simulations in astrophysics, prohibiting large parameter studies in 2D and 3D. Studies spanning a large swath of the incredibly varied initial conditions of CCSNe are possible in 1D, though such simulations must be artificially driven to explode. We present a new method for including the most important effects of convection and turbulence in 1D simulations of neutrino-driven CCSNe, called Supernova Turbulence In Reduced-dimensionality, or STIR. Our new approach includes crucial terms resulting from the turbulent and convective motions of the flow. We estimate the strength of convection and turbulence using a modified mixing-length theory approach, introducing a few free parameters to the model that are fit to the results of 3D simulations. For sufficiently large values of the mixing-length parameter, turbulence-aided neutrino-driven explosions are obtained. We compare the results of STIR to high-fidelity 3D simulations and perform a parameter study of CCSN explosion using 200 solar-metallicity progenitor models from 9 to 120

. We find that STIR is a better predictor of which models will explode in multidimensional simulations than other methods of driving explosions in 1D. We also present a preliminary investigation of predicted observable characteristics of the CCSN population from STIR, such as the distributions of explosion energies and remnant masses.

Published: February 2020

As part of the survey component of the Megamaser Cosmology Project, we have discovered a disk megamaser system in the galaxy CGCG 074-064. Using the Green Bank Telescope and the Very Large Array, we have obtained spectral monitoring observations of this maser system at a monthly cadence over the course of two years. We find that the systemic maser features display line-of-sight accelerations of ∼4.4 km s−1 yr−1 that are nearly constant with velocity, while the high-velocity maser features show accelerations that are consistent with zero. We have also used the High-Sensitivity Array to make a high-sensitivity very long baseline interferometric map of the maser system in CGCG 074-064, which reveals that the masers reside in a thin, edge-on disk with a diameter of ∼1.5 mas (0.6 pc). Fitting a three-dimensional warped disk model to the data, we measure a black hole mass of

and a geometric distance to the system of

Mpc. Assuming a cosmic microwave background-frame recession velocity of 7308 ± 150 km s−1, we constrain the Hubble constant to

(stat.) ± 1.4 (sys.) km s−1 Mpc−1.
Two-temperature Radiative Hot Accretion Flow around Neutron Stars
Authors: Bu De-Fu , Qiao Erlin , Yang Xiao-Hong
Published: February 2020

Numerical simulations of radiative two-temperature hot accretion flows (HAFs) around Neutron stars (NSs) are performed. We assume that all of the energy carried by the HAF around a NS will be thermalized and radiated out at the surface of the NS. The thermal photons will propagate outwards radially and cool the HAF via Comptonization. We define

as the mass accretion rate at the surface of the central object in unit of Eddington accretion rate (

, with L
Edd and c being Eddington luminosity and speed of light, respectively). When

is lower than ∼10−4, the cooling of the HAF is not important and outflows are very strong. When

, cooling becomes important and outflows are significantly weak. In the range

, the dynamical properties of the HAF around a NS are quite similar as those of the HAF around a BH. However, the emitted spectrum of a HAF around a NS can be quite different from that of a HAF around a BH due to the presence of a thermal soft X-ray component coming from the surface of the NS.
Thermodynamics of Dipolarization Fronts of Magnetic Reconnection in Anisotropic Plasma: MMS Observations and Resistive Double-polytropic MHD Simulations
Authors: Teh Wai-Leong , Zenitani Seiji
Published: February 2020

Dipolarization fronts (DFs) of magnetic reconnection are a transient field structure accompanied with a sharp increase of magnetic field component normal to plasma sheet and a high-speed plasma flow. The thermodynamics of DFs in the anisotropic plasma, which have not been studied so far, are investigated in this paper using two-dimensional, resistive magnetohydrodynamic simulations with double-polytropic energy laws in which two polytropic exponents, γ
∥ and

, are used as parameters to describe various thermodynamic conditions. The subscripts ∥ and

denote, respectively, directions parallel and perpendicular to the local magnetic field. Four different types of DFs observed by the Magnetospheric Multiscale Mission (MMS) in the plasma sheet of the Earth's magnetotail are presented—namely, (1) both temperatures T
∥ and

decrease; (2) both T
∥ and

increase; (3) T
∥ decreases while

increases; (4) T
∥ increases while

decreases. By using four different pairs of γ
∥ and

, these four types of DFs can be reproduced, where the thermodynamics of Type-4 DF may correspond to the double-adiabatic Chew–Goldberger–Low conditions. It is concluded that the thermodynamic condition is seen to resemble most closely an adiabatic process for Type-1, -2, and -4 DFs, but to an isothermal process for Type-3 DF.
« L’œil électrique » et « la torpille volante » : pistes pour une histoire du drone à partir de l’histoire télévisuelle
Authors: Weber Anne-Katrin
Published: February 2020

Cet article propose d’étudier l’histoire des drones par le biais de l’histoire de la télévision. S’intéressant plus précisément aux échanges entre les domaines militaire et civil, sa focale s’éloigne d’une étude stricte des drones pour embrasser une approche d’histoire des médias et d’archéologie télévisuelle. Dans cette perspective « élargie » de l’histoire de la télévision, il porte son attention sur les dispositifs télévisuels non institutionnels ; ceux-ci ne participent pas à la définition du mass media diffusant un programme régulier dans les espaces domestiques, mais sont du ressort de domaines relativement négligés par l’historiographie, à savoir le militaire et l’industrie. Le double déplacement – des drones vers la télévision et de la télévision institutionnelle vers la télévision militaire et industrielle – permet de cartographier la circulation des pratiques et des techniques et de souligner la perméabilité des champs militaire et civil, souvent séparés au sein du débat actuel. L’article s’intéresse en particulier à l’imaginaire d’une technologie « sans hommes » qui se retrouve autant dans les discours sur les drones que sur la télévision industrielle. Alors que les deux systèmes sont fortement tributaires des assemblages homme-machine, les discours les concernant mettent en avant une technologie automatisée, voire autonome. Ensuite, l’analyse de la fonctionnalité de l’image télévisuelle militaro-industrielle offre une autre manière de penser les liens entre des pratiques militaires et civiles. Pour cela, l’article recourt à la notion d’« images opérationnelles » (Farocki 2004) qui permet d’appréhender les images télévisuelles non pas en tant que représentations mais en tant qu’instruments. Lorsque voir signifie faire, la destruction et la production deviennent des opérations qui s’apparentent.
La condition fondamentale, c’est nous : implications pour la conscience de masse critique
Authors: Bozarth Jerold D. , Ducroux-Biass Françoise
Published: February 2020

La tendance actualisante et la tendance formative, en tant qu’hypothèses du processus de croissance, peuvent favoriser l’émergence de nouveaux modes de pensée et le développement de l’humanité. Pour l’auteur, l’impact sociétal des travaux de Carl Rogers provient du fait qu’il était davantage motivé par le potentiel de croissance que par le respect pour les individus. Cet article examine l’hypothèse de croissance et l’extrapolation de la théorie de Rogers en lien avec la conscience de masse critique, qui se rapporte au point de changement de la pensée d’un grand nombre d’individus. Le changement de conscience de masse critique est analogue à un changement de paradigme. La médecine et les modèles de psychothérapie traditionnels apparaissent, dans leurs fondements et leurs applications, largement opposés à l’Approche centrée sur la personne. Il en est de même pour les méthodes de pouvoir et de contrôle propres aux orgnisations hiérarchiques. L’auteur questionne l’épistémologie médicale, puise des arguments dans l’expérience menée avec de grands groupes de parole, interroge la multiculturalité et convoque les pratiques vécues de manière non rationnelle et transcendantale. Il rappelle que l’éthique de l’Approche centrée sur la personne est fondée sur les qualités attitudinales du thérapeute et leur perception par le client ainsi que sur la recherche et l’intégration libératrice de ses propres valeurs biologiquement intrinsèques et authentiques.
« All you need is love » ? La psychothérapie guérit-elle par l’amour ?
Authors: Schmid Peter F. , Alleaume Baptiste
Published: February 2020

L’amour est « partout ». Rien ne nous meut ni ne nous occupe autant que l’amour dans ses multiples significations. S’efforcer de comprendre ce que signifie exactement l’amour dans nos relations interpersonnelles, dans notre activité professionnelle, dans la vie privée, l’art, la philosophie et l’éthique, dans la foi etc., tout cela remplit des livres, des vies, l’histoire. Il semblerait qu’il s’agisse d’un effort sans limite pour comprendre sa signification existentielle, sa force, son plaisir, ses menaces. Nombreux sont les théoriciens d’orientation humaniste et existentielle qui considèrent l’amour comme l’élément de guérison ou de qualité de la psychothérapie. D’autres s’opposent et mettent en garde contre l’utilisation de ce mot ambigu pour décrire une relation qui devrait être aussi clairement définie que possible et préfèrent donc une terminologie universitaire. Mais la question va bien au-delà de la terminologie et touche à la nature d’une psychothérapie par la relation. L’amour joue-t-il un rôle dans la psychothérapie ? Et si c’est le cas, quel genre d’amour ? Et comment cela « fonctionne-t-il » ? Est-il adéquat d’aimer un client ? Est-ce bien l’amour qui guérit en thérapie? L’amour est-il au cœur de ce qu’est la thérapie, la facilitation, la « guérison » ? Ou bien s’agit-il simplement d’une façon naïve, superficielle voire nuisible de comprendre l’amour comme agent thérapeutique ? Comment l’amour (thérapeutique) est-il lié au comportement prosocial, à l’altruisme, à l’altérité, à l’intégrité, à la présence, à l’empathie, au regard positif inconditionnel, aux soins, à la réciprocité, au dialogue, au devenir ensemble, à la conscience du corps, à la séduction sexuelle, etc. J’essaierai de donner une analyse approfondie de la question et une description de ma position personnelle sur le rôle que l’amour joue dans la psychothérapie, celle qui est centrée sur la personne en particulier. Ce texte est une version révisée des présentations faites au Symposium européen PCE Symposium Lausanne 2016 et à la Conférence mondiale PCE 2016 à New York.
Littératies en santé et forums de patients : des formes d’ergonomie discursive
Authors: Delavigne Valérie
Published: February 2020

Cet article se propose de discuter de l’articulation entre rédactologie, littératies et terminologie. Nous rappelons tout d’abord le contexte de l’information médicale en France et les enjeux d’une littératie en santé, puis nous explorons les notions de littératie et de littératie en santé en les articulant à une discipline qui n’est guère développée en France : la rédactologie. La description d’un corpus de forums de patients atteints de cancer permet de se demander en quoi la notion d’« ergonomie discursive », qui subsume les pôles respectifs des co- énonciateurs, peut apporter un éclairage sur les problématiques discursives de la vulgarisation.
Quelle sémiotique pour la poésie artistique de Guillaume Apollinaire ?
Authors: Soudani Hind
Published: February 2020

« Poésie » est étymologiquement issu du grec ancien ποίησις (poiesis) signifiant « faire, créer ». Le poète est donc un créateur, un inventeur de formes expressives 1 . C’est en effet ce sens d’art poétique que nous devons garder à l’esprit lorsque nous considérons l’esthétique de l’écriture figurée d’Apollinaire. Cet art du vu et du lu dans la mise en place de la compréhension et de l’interprétation du message par le récepteur. Un univers graphique dessinant l’objet de l’écrit lui permettant ainsi une corrélation profonde entre l’image et l’imagination tout en subvertissant le signe linguistique qui, désormais, signifie au moyen de la représentation de son signifiant. Cela justifie tant la première appellation d’« Idéogrammes lyriques » donnée par Apollinaire à ses figurations que le titre « Et moi aussi je suis peintre » 2  dont il désigne la première plaquette de ce qu’il nommera plus tard « Calligrammes ». Une innovation poétique en apparence formelle, mais donnant lieu à un mode de fonctionnement à multiples facettes intéressant à étudier du point de vue sémiotique. Ainsi, à l’ère des nouveaux outils de représentation, de tels jeux figuratifs stimulent la curiosité du récepteur et investissent l’art poétique d’une modernité qui lui garantit de demeurer captivant et riche en mystère.
« Don’t begin with proportion » : le postulat contradictoire de la mesure dans l’adaptation de Howards End (James Ivory)
Authors: Mellet Laurent
Published: February 2020

Cet article propose plusieurs interprétations du postulat de la mesure, observable dans l’adaptation de Howards End par la société de production Merchant-Ivory. Alors que, dans le roman de Forster, on refuse d’abord de faire le choix de la mesure ( proportion ) et qu’un certain nombre de contradictions s’avèrent être au cœur de l’écriture des personnages comme des logiques narratives, le film d’Ivory fait de cette mesure un postulat narratif et formel. Nous proposons une lecture de l’adaptation orientée par ce rapport contradictoire au roman, avant de suggérer que ce choix témoigne d’une conception de l’adaptation plus originale que ce que la critique retient le plus souvent des films produits par la Merchant-Ivory, et qui signale un retour à certaines logiques forstériennes.
« On the surface of it » : John Ashbery au miroir
Authors: Cazé Antoine
Published: February 2020

Quel reflet de soi John Ashbery offre-t-il dans le « miroir convexe » de ses poèmes ? À partir d’une analyse de l’apparente obscurité d’une poésie peut-être sans sujet, cet article montre en quoi une surface textuelle aux limites de l’illisible permet à son auteur de réfléchir aux conditions même de visibilité sur lesquelles se fonde l’écriture. Prenant pour fil directeur la conférence sur John Clare prononcée en 1989 par John Ashbery à Harvard, nous explorons ce que le poète appelle la « condition de difficile visibilité » (« Sunrise in Suburbia ») dans laquelle se déploie son écriture, qui trouve son accomplissement dans les longues séquences de vers si caractéristiques que sont « Self-Portrait in a Convex Mirror » ou le plus ancien « The Skaters ». Il s’agit de comprendre en quoi ce déploiement, qui n’est pas pour autant une quelconque explication, configure un sujet dont « l’infinité de replis » (Louis Marin) constitue une profondeur en trompe-l’œil.
Gold and Bones: Remains of the Quest in Song of Solomon
Authors: Raynaud Claudine
Published: February 2020

L’un des mystères du Chant de Salomon tourne autour du contenu du sac de Pilate, son « héritage », qui s’avère n’être ni l’or convoité ni les ossements du vieil homme blanc assassiné, mais les os de son père qu’elle doit alors inhumer. Cet essai retrace le symbolisme du contenu du sac, l’or et les os, qui fonctionne comme métonymie du roman lui-même à travers les projections et les interprétations, erronées, puis rectifiées qu’il suscite. La quête de l’or poursuivie par Milkman se résout lorsqu’il redirige sa recherche vers sa lignée et sa liberté de voler. Le motif de la relique, du memento mori , tel que le texte le retravaille, conduit à une analyse de ce qui reste du corps du père mort (le père de Pilate, celui de Ruth, celui de Guitar), de ce qu’il en est de la division entre corps et chair. Lié à la thématique du lynchage, le sac qui renferme les os du père noir cristallise le sujet profond de ce roman que Morrison a écrit à la mémoire de son père défunt, « Papa. »
L’ordinaire de la sortie de guerre
Authors: Grajales Jacobo , Jouhanneau Cécile
Published: February 2020

Afin de rendre compte des processus politiques et sociaux à l’œuvre dans la sortie de guerre, ce dossier explore la production de l’action publique dans des secteurs fréquemment négligés par les spécialistes du « post-conflit ». Il se situe ainsi à rebours des approches exceptionnalistes du « post-conflit », focalisées sur les bouleversements induits par la guerre et sur des dispositifs singuliers visant la construction de la paix ( peacebuilding ). L’enjeu est donc de repérer empiriquement les articulations entre la guerre, les efforts visant à y mettre fin, et d’autres sphères d’action publique. L’article introductif relie cette posture à des travaux récents insistant sur l’ordinaire dans les situations de guerre, propose un bref état des lieux de la recherche et s’attarde sur les principaux objectifs du dossier : réfléchir aux usages multiples de la catégorie de « post-conflit » dans la fabrique de l’action publique et retracer les diverses manières dont un passé guerrier peut avoir une emprise sur les politiques publiques.
Au cœur du gouvernement internationalisé de la sortie de guerre
Authors: Jouhanneau Cécile
Published: February 2020

La guerre transforme-t-elle la fabrique de l’action publique et si oui, comment ? En prenant pour objet un segment négligé de l’action publique en Bosnie-Herzégovine, le service public de l’emploi, on met en évidence les continuités relatives du gouvernement de l’emploi avant, pendant et après la guerre de 1992-1995. L’enquête conduite à différents niveaux de la fabrique de l’action publique, des institutions financières internationales aux échelons entitaires, cantonaux et municipaux suggère que les relations entre les agents de l’intervention de paix et leurs interlocuteurs politiques bosniens sont faites de dépendance mutuelle et de pratiques d’externalisation du travail bureaucratique. De façon similaire à la Yougoslavie socialiste, les partis de gouvernement pèsent de façon discrète sur la fabrique de ces politiques. Apparaissent ainsi certaines modalités contemporaines de gouvernement internationalisé.
De rebelle à fonctionnaire
Authors: Popineau Camille
Published: February 2020

Cet article analyse le profil et les trajectoires des acteurs intégrant les régies financières de Côte d’Ivoire à la suite des accords de paix mettant fin au conflit armé (2002-2011), en réinterrogeant le débat sur les continuités et les ruptures introduites par la guerre sur l’État. Je montre que les personnes qui intègrent l’État sont d’anciens syndicalistes étudiants ayant fait leurs armes à la fois dans les luttes estudiantines violentes des années 1990, puis dans la rébellion des Forces nouvelles. Si le capital social tiré de ces deux périodes leur ouvre les portes de l’État, la capacité à reconvertir ensuite ce capital en capital symbolique légitimant la mobilisation politique sur le plan local et national n’est pas également partagée. La reconversion est fonction d’un certain volume de capital social accumulé pendant la période de la rébellion, volume qui est lui-même fonction de l’appartenance à certaines générations d’étudiants avant le conflit. Le syndicalisme étudiant apparaît comme une nouvelle filière d’accès au champ politico-administratif ivoirien dans la période post-conflit, mais l’entrée en politique et l’ascension sociale qui en découle ne concernent qu’une partie d’entre eux, à savoir les plus dotés, reproduisant ainsi des hiérarchies sociales déjà en place au sein des syndicats étudiants puis de la rébellion. L’article met ainsi l’accent sur les trajectoires longues des acteurs pour comprendre finement dans quelle mesure les processus d’intégration des rebelles à l’État impactent ce dernier et le modifient, en termes de composition des agents étatiques, de profils des fonctionnaires et de hiérarchies sociales.
Quelle justice climatique pour la France ?

Published: February 2020

Notre propos dans cet article est de comprendre comment la France peut appréhender la problématique de la justice climatique et envisager le projet qu’elle pourrait développer, en particulier sous l’angle des politiques publiques. De la justice climatique revendiquée pour réparer une dette écologique à la justice climatique comme principe d’action reconnu et mis en œuvre dans les politiques publiques, de nombreuses perspectives apparaissent pour penser un modèle de développement plus solidaire et respectueux des droits de chacun, y compris des plus vulnérables et des plus démunis.
Structural changes in gut microbiome after Ramadan fasting: a pilot study
Authors: Ozkul C. , Yalinay M. , Karakan T.
Published: February 2020

It has been largely accepted that dietary changes have an effect on gut microbial composition. In this pilot study we hypothesised that Ramadan fasting, which can be considered as a type of time-restricted feeding may lead to changes in gut microbial composition and diversity. A total of 9 adult subjects were included in the study. Stool samples were collected before (baseline) and at the end of the Ramadan fasting (after 29 days). Following the construction of an 16S rRNA amplicon library, the V4 region was sequenced using the Illumina Miseq platform. Microbial community analysis was performed using the QIIME program. A total of 27,521 operational taxonomic units (OTUs) with a 97% similarity were determined in all of the samples. Microbial richness was significantly increased after Ramadan according to observed OTU results (P=0.016). No significant difference was found in terms of Shannon index or phylogenetic diversity metrics of alpha diversity. Microbial community structure was significantly different between baseline and after Ramadan samples according to unweighted UniFrac analysis (P=0.025). LEfSe analysis revealed that Butyricicoccus, Bacteroides, Faecalibacterium, Roseburia, Allobaculum, Eubacterium, Dialister and Erysipelotrichi were significantly enriched genera after the end of Ramadan fasting. According to random forest analysis, the bacterial species most affected by the Ramadan fasting was Butyricicoccus pullicaecorum. Despite this is a pilot study with a limited sample size; our results clearly revealed that Ramadan fasting, which represents an intermittent fasting regime, leads to compositional changes in the gut microbiota.

Published: February 2020

Machining has been one of the most sort of process for realizing different products. It has significant role in the value additions process. Machining is one of the production process where material is removed from the parent material to realize the final part or component. Among machining, the well known machining processes are turning, milling, shaping, grinding and non-conventional machining processes like electric discharge machining, ultrasonic machining, chemical machining etc. The fundamental of all these processes being material removal in the form of chips using a tool either in contact or not in contact. In the present work, milling is being taken for study Finite element analysis is being used as a tool to understand the different phenomenon that underlies the machining processes. Of late, the machining induced residual stresses is of great interest to the researchers since the residual stresses have an impact on the functional performances. The present work is to model the milling process to predict the forces and residual stresses using finite element method. Unlike many researchers, the authors have attempted to develop oblique cutting model rather than an orthogonal cutting model. The present work was carried out on AISI 1045 steel.

In the current work, wear behavior of plasma processed LM6 alloy is investigated. LM6 alloy was prepared by plasma technique. The samples were aged at 350°C & 450°C for 2 hours followed by water quenching. A comparative study of the metallographic structure and properties viz. hardness, density and wear of the non-heat and heat treated alloy samples were carried out. A very fine lamellar structure is observed in case of 450°C heat treated samples than that of sample heat treated at 350°C and non-heat treated samples. Highest hardness value of 68.11 VHN is observed with the sample heat treated at 450°C. Density is found to be the lowest in non-heat treated samples and it increases with increasing heat treatment temperature. Wear experiments were carried on a pin-on-disc set up (of Ducom make), varying applied loads (between 10-40Newton and varying sliding speed (from 0.94 m. s-1 to 2. 83m.s-1). Maximum wear resistance is observed with the specimen heat treated at 450°C.

Materials performance plays a pivotal role to the smooth operation of present and future nuclear energy systems operating in severe irradiation environment in reactors. Therefore selection of structural materials with the desired properties is vital for this field of applications. The present work reports the effect of milling time during mechanical alloying of a novel Oxide Dispersed metal matrix composite consisting of multi-component AlCrFeMnNi high entropy alloy system with minor addition of Partially Stabilized Zirconia (PSZ) (1 wt.%). The main focus of this work is to understand the phase stability behaviour during mechanical alloying. High Entropy Alloy AlCrFeMnNi with Partially Stabilized Zirconia (PSZ) as Dispersoid phase was prepared by mechanical alloying. For study of phases, milled powder was investigated through X-Ray diffraction technique followed by Scanning Electron Microscopy for microstructural morphology. The study reveals that PSZ Dispersed AlCrFeMnNi alloy mainly consists of BCC (Fe Type) and FCC (Ni Type) mixed structure. At the end of 30 h lattice strain and crystallite size were measured to be 0.738 % and 13 nm respectively.

The present work deals with the synthesis and characterization of Al-Cu-SiC-Al2O3 hybrid metal matrix composite with varying percentage of Al2O3. The synthesized hybrid composite samples were conventionally sintered at two different sintering temperatures i.e. 500°C and 600°C for 1 hr each. SEM investigation predicts the uniform distribution of reinforcing particles. The SEM and XRD results of the sintered composites revealed the presence of a new intermetallic alloy CuAl2 phase along with Al and SiC phases. It is observed that the density and hardness of Al-Cu-SiC-Al2O3 hybrid composite increases with increase in wt % of Al2O3 and sintering temperature.

The basic aim in using the waste is to reduce the level of pollution that harms the environment. However a proper approach to manage waste or reduce the level of waste helps in conservation of resources for the succeeding generation and contributes to a healthy, clean and pollution free environment. In recent years, control on two major ecological issues such as waste disposal and noise pollution can help in achieving a green and healthier environment. For disposal, waste tires are normally burnt. Extinguishing fire from tire is very difficult. The fire develops a thick, dark smoke which contains CO2, SO2, cyanide, and products of butadiene & styrene. This study focuses on the fabrication of composites from epoxy-waste tire crumb by hand lay-up method and the investigation of its acoustical property by Impedance tube method using LABVIEW. In the present work three different materials such as PVC, Stainless Steel and Glass has been used to prepare impedance tube as per ASTM standards. All the sound testing has carried out at a frequency range of 500 Hz to 5000 Hz. This study clearly shows a promising waste management for tyres by developing a cost effective composite and thus contributing to a sustainable waste granule (waste tyre) reinforced polymer composite industry.

Published: February 2020

Fiber reinforced polymeric (FRP) composite materials are currently used in numerous structural and materials related applications. But, during their in-service period these composites were exposed to different changing environmental conditions. Present investigation is planned to explore the effect of thermal shock exposure on the mechanical properties of nanoTiO2 enhanced glass fiber reinforced polymeric (GFRP) composites. The samples were conditioned at +70°C temperature for 36 h followed by further conditioning at – 60°C temperature for the similar interval of time. In order to estimate the thermal shock influence on the mechanical properties, tensile tests of the conditioned samples were carried out at 1 mm/min loading rate. The polymer phase i.e. epoxy was modified with different nanoTiO2 content (i.e. 0.1, 0.3 and 0.5 wt. %). The tensile strength of 0.1 wt.% nanoTiO2 GFRP filled composites exhibited higher ultimate tensile strength (UTS) among all other composites. The possible reason may be attributed to the good dispersion of nanoparticles in polymer matrix corresponds to proper stress transfer during thermal shock conditioning. In order to access the variations in the viscoelastic behavior and glass transition temperature due to the addition of nanoTiO2 in GFRP composite and also due to the thermal shock conditioning, dynamic mechanical thermal analysis (DMTA) measurements were carried out. Different modes of failures and strengthening morphology in the composites were analyzed under scanning electron microscope (SEM).

Polyvinylidene fluoride (PVDF) – Lead Zirconate Titanate (PZT) is a polymer composite that is becoming increasingly popular in micro-scale sensors and actuators because of its unique properties such as high flexibility, low density and high piezoelectric constants. However, lead-based piezoceramics, despite their superior properties, are toxic and are known to damage the environment, and as such a conscientious effort is being made by the scientific community towards replacing lead-containing piezoceramics with environmentally-friendlier and lead-free piezoceramics. Barium Titanate (BaTiO3) is one such piezoceramics that is widely studied today to be a potential replacement of PZT in many applications. As such, in this work, effort has been made to predict the effective mechanical, dielectric and piezoelectric properties of PVDF-BaTiO3 composite system using Finite Element Method (FEM). Kinematic Uniform Boundary Conditions (Displacement and Voltage) are used for this analysis. For evaluation of the effective material constants of the composite, several types of representative volume elements are considered. The effects of volume fraction, effect of the size of the micro-particles i.e. mono-modal versus multi-modal size distribution, effect of periodic versus quasi-random distribution of microparticles in the matrix, the effect of clustering of the particles, effect of orientation of the microparticles i.e. unidirectional or randomly oriented are discussed. Finally, a comparison of properties between PVDF-PZT and PVDF-BaTiO3 is made, so as to see whether PVDF-BaTiO3 can be a potential replacement for PVDF-PZT composite.

The materials significantly influence the structural, optical and photoelectrical characteristic. Materials such as Arsenic selenide, Tellurite Glass, Silicon carbide, Silicon dioxide and Silicon nitride are investigated through finite element method. The models are established to analyse the structural behaviour of polarization preserving fibre of proposed materials. Photoelectric characteristic determines guided properties of photon particles. Refractive index of the materials influences the properties of photonic crystal fibre. A Polarization Splitter based hexagonal structure is proposed, where inner ring of cladding is in elliptical shape air holes and outer rings are in circular air holes. It provides highly negative dispersion, low confinement loss and high nonlinear coefficient between 1µm to 2µm wide wavelength ranges. The dispersion result shows -2000 db/km-nm at 1.55µm wavelength. Polarization beam splitters photonic crystal fiber characteristics of proposed materials are analysed with same structural parameters.

Graphene, the most unique member of carbon family has fuelled a huge interest across the globe with its superior mechanical, chemical, optical and electronic properties. It has opened enormous avenues for humankind in terms of different applications. Since its discovery in 2004, people have tried various techniques to extract graphene, such as mechanical exfoliation, chemical exfoliation, epitaxial growth, CVD (chemical vapour deposition) etc. However, the above methods are not optimal for mass production, neither are they simple and cost effective. The present work highlights synthesis of graphene through electrochemical approach and its subsequent characterization. Pyrolytic graphite is subjected to intercalation of two different concentrations of HNO3 electrolyte. XRD, FESEM and TEM were utilised to understand the structure and morphology of the obtained few-layer graphene nanosheets (FLGNs). Scanning probe spectroscopy is a useful technique for understanding the morphological structure of a sample at atomic level. Authors have utilised AFM which shows the thickness of the FLGNs to be in the range of 5-6 nm. STM studies of graphene nanosheets revealed atomic scaled periodicity and atomic flatness.

Electric Discharge Machining (EDM) is a thermo-electrical disintegration process, utilized to cut hard materials into complex shapes. In EDM, the three vital components are work-piece material, electrode material and dielectric liquid. The significant function of the dielectric fluid is to produce a breakdown voltage for creating a spark between work-piece and electrode. This spark creates ionization by plasma generation and it expels the material from work-piece. In most cases, hydrocarbon-based dielectric liquid is preferred in the EDM process. This kind of dielectric liquid generates hazardous gases which are harmful to people, environment and ecological balances. In this experiment, Canola oil is utilized and the outcomes are compared. The input parameters are Pulse on/off time, current and gap voltage. Copper, Brass and Tungsten-Copper (Alloy) are used as electrodes. The output values from the experiments are Surface Roughness (SR), Electrode Wear Rate (EWR) and Material Removal Rate (MRR). The outcomes demonstrated that Canola oil-based dielectric fluid has comparable properties of conventional based dielectric fluid. This Canola based dielectric gives more prominent MRR value than EDM oil-based dielectric liquid and furthermore higher EWR and SR values are recorded. The proposed Canola oil-based dielectric fluid is biodegradable and has improved suitability in machining.

Published: February 2020

One of the most important and widely visualized process taking place in nature is condensation. Superhydrophobic surfaces, which facilitates dropwise condensation has been the principal area of research in the last decade or so. Fabrication of superhydrophobic surface can be achieved by either surface modification using mechanical process, surface treatment like coating or by the combination of both. But, the major drawback of coating is its durability and vulnerability. So, in this work we have fabricated a robust surface by means of picosecond laser machining. Apart from being a simple process, this method has an advantage of cutting down the surface fabrication time by several hours as compared to other methods like one-step immersion, electro-deposition, top-down fabrication method, etc. In our work three different work specimens irradiated with different laser power were studied for its surface morphologies by scanning electron microscope (SEM) images and its wettability was measured using contact angle meter. It is found that the wettability of surface changes with different laser power and hence it is possible to control the wettability by adjusting the laser parameters. Condensation experiment was carried out on these different surfaces and its performance was compared with plain surface.
