Résumé :
The present work is focused on the study of traversable wormholes, proposed by Morris and Thorne [Wormholes in spacetime and their use for interstellar travel: A tool for teaching general relativity, Am. J. Phys. 56 (1988) 395], using the background of modified gravity. It is performed by using the models: I. [Formula: see text], II. [Formula: see text] and III. [Formula: see text], where [Formula: see text], [Formula: see text] and [Formula: see text] are constants. The Model I belongs to the theory of [Formula: see text] gravity, Model II belongs to the theory of [Formula: see text] gravity and Model III is a combination of Models I and II. These functions have been taken into account for the exploration of wormhole solutions. The shape function, a wormhole metric function, is newly defined which satisfies the flare out condition. Further, the stability condition and energy conditions, namely null, weak and dominant energy conditions, have been examined with respect to each model.

Résumé :
Morris and Thorne [M. S. Morris and K. S. Thorne, Am. J. Phys. 56, 395 (1988)] proposed geometrical objects called traversable wormholes that act as bridges in connecting two spacetimes or two different points of the same spacetime. The geometrical properties of these wormholes depend upon the choice of the shape function. In the literature, these are studied in modified gravities for different types of shape functions. In this paper, the traversable wormholes having shape function [Formula: see text] are explored in [Formula: see text] gravity with [Formula: see text], where [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] are real constants. For different values of constants in function [Formula: see text], the analysis is done in various cases. In each case, the energy conditions, equation of state parameter and anisotropic parameter are determined.

In this work, we study the dark energy accretion phenomena onto [Formula: see text]-dimensional Schwarzschild black hole and [Formula: see text]-dimensional Morris–Thorne wormhole. We obtain the [Formula: see text]-dimensional Schwarzschild black hole mass and [Formula: see text]-dimensional Morris–Thorne wormhole mass and their rate of change of masses due to accretion. For the dark energy component, we consider Tsallis, modified Rényi and “modified” Sharma–Mittal holographic dark energy (HDE) and new agegraphic dark energy (NADE). We also find the black hole mass and the wormhole mass in terms of redshift when cold dark matter and the specified forms of dark energies accrete onto them. In most cases, the black hole mass increases, and wormhole mass decreases for HDE and NADE accretions. The only exception is the Sharma–Mittal NADE, where the black hole mass decreases and wormhole mass increases during the evolution of the Universe. However, the slope of increasing/decreasing mass significantly depends on the dimension in almost all cases.

AbstractThe present paper reports a study on accreting tachyon, Dirac-Born-Infeld essence and h-essence scalar field models of dark energy onto Morris-Thorne wormhole. Using three different parameterisation schemes and taking $H\, = \,{H_0}\, + \,{{{H_1}} \over t}$, we have derived the mass of the wormhole for all of the three parameterisation schemes that are able to get hold of both quintessence and phantom behaviour. With suitable choice of parameters, we observed that accreting scalar field dark energy models are increasing the mass of the wormhole in the phantom phase and the mass is decreasing in the quintessence phase. Finally, we have considered accretion with power law form of scale factor and without any parameterisation scheme for the equation of state parameter and observed the fact that phantom-type dark energy supports the existence of wormholes.

Texte intégral
Résumé :
Viaggiare da un punto all'altro dell'universo muovendosi in uno spazio-tempo piatto richiede tempi talmente colossali da risultare impossibile per la nostra razza; pertanto, un viaggio interstellare potrebbe essere realizzato solo per mezzo di topologie relativistiche in grado di accorciare la distanza fra i punti dell'universo. Dopo aver dato una serie di motivazioni per cui i buchi neri ed il ponte di Einstein-Rosen non sono adatti ad essere impiegati viene introdotta una particolare classe di soluzioni, presentata per la prima volta da Michael S. Morris e Kip S. Thorne, delle equazioni di Einstein: essa descrive wormholes i quali, almeno in linea di principio, risultano attraversabili dagli esseri umani in quanto non presentano un orizzonte degli eventi sulla gola. Quest'ultima proprietà, insieme alle equazioni di campo di Einstein, pone dei vincoli piuttosto estremi sul tipo di materiale in grado di dar luogo alla curvatura spazio-temporale del wormhole: nella gola del wormhole la materia deve possedere una tensione radiale di enorme intensità, dell'ordine di quella presente nel centro delle stelle di neutroni più massive per gole con un raggio di appena qualche kilometro. Inoltre, questa tensione dev'essere maggiore della densità di energia del materiale: ad oggi non si conosce alcun materiale con quest'ultima proprietà, la quale viola entrambe le "condizioni sull'energia" alla base di teoremi molto importanti e verificati della relatività generale. L'esistenza di questa materia non può essere esclusa a priori, visto che non esiste prova sperimentale o matematica della sua irrealisticità fisica, ma non essendo mai stata osservata è importante assicurarsi di impiegarne il meno possibile nel wormhole: questo ci porterà a mostrare che i wormholes in cui il materiale esotico presenta una densità di energia negativa per gli osservatori statici sono i più adatti al viaggio interstellare.

Résumé :
Questa tesi si occupa della questione della stabilità lineare di wormholes (tunnel spaziotemporali) statici e a simmetria sferica, supportati da campi scalari di tipo fantasma autointeragenti, nel contesto della Relatività Generale per spazitempi di dimensione arbitraria. In letteratura, attraverso un'analisi gauge-invariante delle configurazioni di tipo wormhole, spesso si riesce a disaccoppiare le equazioni di campo linearizzate, ottenendo un'equazione delle onde (master equation) che, tuttavia, tipicamente è singolare dove il coefficiente radiale della metrica ha un punto critico, cioè nella gola del tunnel. Per risolvere questo problema, nei lavori passati è stato proposto un metodo di regolarizzazione che trasforma l'equazione delle onde singolare in una regolare; questo metodo è solitamente denominato "S-deformazione" (e spesso richiede parzialmente un'implementazione numerica, specialmente nel caso di campi scalari con un'autointerazione non banale). Il primo risultato del mio lavoro è la riduzione delle equazioni di campo linearizzate ad un sistema delle onde vincolato e completamente regolare, per due funzioni gauge-invarianti delle perturbazioni dei coefficienti della metrica e del campo scalare, opportunamente definite; il secondo risultato è una strategia per disaccoppiare questo sistema, ottenendo una sola master equation delle onde per un'altra quantità gauge-invariante. Nessun passaggio di questa costruzione determina l'apparizione di singolarità nella gola del tunnel o in altri punti (sempre che il campo scalare imperturbato non abbia punti critici, cosa che accade in moti esempi); quindi non è necessario regolarizzare a posteriori la master equation utilizzando il metodo di S-deformazione. Questo formalismo gauge-invariante e libero da singolarità, che generalizza a dimensione arbitraria l'approccio del mio articolo [1], è applicato ad alcune soluzioni di tipo wormhole statiche note (la maggior parte, ma non tutte, considerate in [1]). La più importante applicazione è ad un wormhole Anti-de Sitter (AdS), la cui stabilità lineare non pare sia mai stata analizzata da altri autori finora; utilizzando il presente metodo è possibile derivare una master equation completamente regolare che descrive le perturbazioni del wormhole AdS e quindi dimostrare che quest'ultimo è linearmente instabile, dopo aver dettagliatamente analizzato le proprietà spettrali di un operatore di tipo Schrödinger che compare nella master equation. Sulla stessa linea, è ottenuto un risultato parziale per l'analogo wormhole di tipo de Sitter (dS), caso tecnicamente più sottile a causa della presenza di orizzonti. Come ulteriore applicazione, ho riottenuto in maniera libera da singolarità le master equations per le perturbazioni di dei wormholes di Ellis-Bronnikov e di Torii-Shinkai. Ad integrazione, l'instabilità lineare dei wormholes AdS e di Torii-Shinkai sono riottenute utilizzando un metodo alternativo, privo di singolarità ma gauge-dipendente: in questo caso, si ottiene una master equation per la perturbazione della coordinata radiale, e l'indipendenza dal gauge del risultato di instabilità è testata a posteriori. Questo approccio alternativo e gauge-dipendente generalizza quello introdotto in [2] per il wormhole di Ellis-Bronnikov a simmetria riflessiva. Vorrei citare infine [3], dal quale ho riportato alcuni fatti sui wormholes appena menzionati in assenza di perturbazione. BIBLIOGRAFIA: [1] F. Cremona, L. Pizzocchero, and O. Sarbach.

In this thesis I deal with the linear stability analysis of static, spherically symmetric wormholes supported by phantom self-interacting scalar fields, in the framework of General Relativity with arbitrary spacetime dimension. In the previous literature, a gauge-invariant stability analysis of wormhole configurations often succeeds in decoupling the linearized field equations, yielding a wave-type master equation which, however, is typically singular where the radial coefficient of the metric has a critical point, that is, at the wormhole throat. In order to overcome this problem a regularization method has been proposed in previous works, which transforms the singular wave equation to a regular one; this method is usually referred to as “S-deformation” (and sometimes requires a partly numerical implementation, especially, in the case of scalar fields with nontrivial self-interaction). The first result of my work is the reduction of the linearized field equations to a completely regular, constrained wave system for two suitably defined gauge-invariant functions of the perturbations in the metric coefficients and in the scalar field; the second result is a strategy for decoupling this system, obtaining a single wave-type master equation for another gauge-invariant quantity. No step of this construction causes the appearing of singularities at the wormhole throat or elsewhere (provided that the unperturbed scalar field has no critical points, which occurs in many examples); therefore, it is not necessary to regularize a posteriori the master equation via the S-deformation method. This gauge-invariant and singularity-free formalism, which generalizes to arbitrary spacetime dimensions the approach of my paper [1], is then applied to some known static wormhole solutions (most, but not all of them considered in [1]). The most relevant application is a certain Anti-de Sitter (AdS) wormhole, whose linear stability analysis does not seem to have been performed previously by other authors; by using the present method, it is possible to derive a completely regular master equation describing the perturbations of the AdS wormhole and prove that the latter is actually linearly unstable, after providing a detailed analysis of the spectral properties of the Schrödinger type operator appearing in the master equation. A partial instability result is derived along the same lines for the analogous de Sitter (dS) wormhole, a technically more subtle case due to the presence of horizons. As a further application, I rederive in a singularity-free fashion the master equations for the perturbed Ellis-Bronnikov and Torii-Shinkai wormholes. As a supplement, the linear instability results for the AdS and for the Torii-Shinkai wormholes are also recovered using an alternative, singularity free but gauge-dependent method: in this case a regular master equation is derived for the perturbed radial coordinate, and the gauge-independence of the instability result is tested a posteriori. This alternative, gauge-dependent approach generalizes that introduced in my paper [2] for the reflection symmetric Ellis-Bronnikov wormhole. Let me also cite [3], from which I report some facts about the previously mentioned wormholes in absence of perturbations. BIBLIOGRAPHY: [1] F. Cremona, L. Pizzocchero, and O. Sarbach.

Texte intégral
Résumé :
This book delves into the inadequately explored, liberative side of Humanism during the late Renaissance. While some long-sixteenth-century thinking anticipates twentieth-century Liberation Theology, a broader description is simply "liberation thinking," which embraces its diverse, timeless, and sometimes nontheological aspects. Two moments frame the treatment of American colonialism’s physical and mental pathways and the liberative response to them, known as liberation thinking. These are St. Thomas More’s Utopia, published in 1516, and Felipe Guaman Poma de Ayala’s thousand-page Nueva crónica y buen gobierno, completed one hundred years later. These works and others by Erasmus and Bartolomé de las Casas trace the development of the idea of human liberation in the face of degrading chattel and encomienda slavery as well as the peonage that gave rise to the hacienda system in the Americas. Catholic humanists such as More, Erasmus, Las Casas, and Guaman Poma developed arguments, theories, and even theology that attempted to deconstruct those subordinating structures.

Résumé :
What do corporate morals entail? Since Émile Durkheim’s assertion that in the business world, no professional morals prevail several scholars have tried to debunk his assertion by specifying such morals. This chapter reviews these efforts from the middle of the twentieth century with the consolidation of management as a profession to recent developments in the making of corporate cultures. The chapter shows that these scholarly efforts have led to a better understanding of certain aspects of corporate morals, but also notes that a defining feature of corporate morals seems to be their elusive quality. It argues that scholars’ difficulty in pinpointing the contents of corporate morals might tell us a lot about those morals themselves. More specifically, the author proposes that manager under-specification of morals suggests an underlying commitment to moral relativism. Thus the elusiveness of corporate morals might be an artefact of the morals themselves.

Sets the framework of the book within contemporary theories of the history of emotions and the history of morality, making a case for the use of ‘moral economy’ as an analytical category that connects theories of the biological evolution of civilized emotions to scientific practices of those theories. The Darwinian explanation of sympathy thus becomes a scientific practice of sympathy, both defining the self and the meaning of scientific moral action, and a raft of public policies and research agendas.

All responsible inquiry into the contemporary state of avant-garde art must acknowledge the possibility that no such art exists. Such non-existence would be dismaying news for a lot of people because, despite the possibility that the concept refers to nothing, many writers and artists continue to invest in it as if its capacity to illuminate contemporary artistic and aesthetic practices were a given. If one inclines towards believing that there was an American avant-garde in those years, one is likely to find that Sayre's roster of participating figures includes the expected artists and movements: Carolee Schneeman and Robert Morris, Judy Chicago and Robert Smithson, Fluxus and the Judson Dance Theater, and so on.

Texte intégral
Résumé :
Chapter 6 turns from the explication and defense of legal punishment as a general practice to the task of developing and defending the fair-play theory of punishment in particular. As developed by Herbert Morris and others, the theory holds that punishment is justified, ceteris paribus, because law breakers try to enjoy the benefits of a legal system without bearing its burdens, thereby taking unfair advantage of those who obey the laws. I elaborate this account by drawing out the connection between legal systems and cooperative practices, arguing that the analogy between fair play in a game and fair play in a polity, or legal system, is not simply misguided. I then respond to five serious objections that critics have leveled against fair play as an account of punishment. I conclude by considering the gentler complaint that fair play is too narrow to provide a satisfactory justification for legal punishment.

Texte intégral
Résumé :
This chapter presents a model of the Incarnation developed on the basis of the Na’vi avatars of the science fiction movie Avatar. The model does not address the metaphysics of the Incarnation; rather, its main concern is with the consciousness of Jesus Christ, the incarnate Son. “One-sphere models,” in which the Son while incarnate has a single sphere of consciousness, are examined and found to be unsatisfactory. The avatar model is a “two-sphere model,” in which there exist distinct spheres of consciousness for the divine nature and the human nature, similar to the “two minds” view proposed by Thomas Morris. It is argued that this does not amount to Nestorianism. The possibility of a single person with multiple spheres of consciousness is defended by comparison with the psychological “split-brain” and “multiple personality” phenomena; this way of understanding those phenomena is defended against a contrary view expounded by Tim Bayne.

Résumé :
American Nobel Laureate Toni Morrison’s 11th novel, God Help the Child, released in 2015, set in contemporary times, explores the relationship between a financially successful, beautiful young Black woman with a haunted past and an intelligent disaffected young Black man who is equally alienated from his past. This collection of essays, edited by Morrison scholars Alice Knox Eaton, Maxine Lavon Montgomery, and Shirley A. Stave, and including essays by well-known Morrison critics Evelyn Schreiber, Mar Gallego, Susana Vega, Anissa Wardi, and Justine Tally, explores the novel’s themes and tropes through a multiplicity of critical and theoretical approaches. The first of the collection’s three sections focuses on the issue of trauma in the novel. The various essays featured here delve into the thorny topic of childhood neglect and sexual abuse, considering how the main characters carry the burden of the pain they experienced into adulthood. These essays probe the healing achieved in the novel through various approaches, all focused on arriving at an understanding of Morrison’s sense of what healthy adulthood entails. The collection’s second section considers Morrison’s narrative choices in her novel, concentrating on the formal experimentation that occurs within the text. The authors in this section reflect upon the myriad ways in which Morrison's novel relies upon intertextual play in the creation of a fictional cosmology that engages the reader on multiple levels. Essays included in the collection's final section turn attention to God Help the Child in terms of the novel's signifying relation with earlier Morrison texts, bringing into sharp focus the predominant concerns throughout Morrison's fictional canon, from her debut work of fiction, The Bluest Eye, until the present.

Résumé :
This book highlights a seminal but largely overlooked period in the development of American counterinsurgency strategy. It examines how Progressive counterinsurgency ideas and methods evolved between 1899 and 1913 as Americans fought Philippine Moros in their first sustained military encounter with Islamic militants. It then compares those ideas and methods with current theory on COIN (counterinsurgency) as set forth in The U.S. Army * Marine Corps Counterinsurgency Field Manual. The author also explores how Moros contested American military intervention in their lives. He asks: How did they bend the narrative? How did Progressive counterinsurgency in Mindanao and Sulu come to have a Moro face? Finally, this work focuses on how John J. Pershing, during his seven years of service among Moros, contributed to Progressive counterinsurgency strategy. How did his approach compare with Gen. Leonard Wood’s radically different ideas on pacification? In the most creative years of Pershing’s life, how did he pull together lessons learned from his Philippine experience to craft a relatively balanced and full-spectrum approach to fighting small wars? What can we take from his experience and apply to America’s fraught relationship with Islamic militancy today?

AbstractArguably the greatest challenge within Oral and Maxillofacial Surgery is reconstruction following major trauma or oncologic ablative surgery that restores the patient’s pre-morbid quality of life. Satisfactory reconstruction of the maxillofacial region needs to address both cosmetic and often functional concerns beyond those encountered at other sites in the body. Even small facial defects can lead to cosmetic deformity that impacts significantly on a patient’s psychosocial well-being if not reconstructed appropriately. There have been many technological advances over the last few decades, particularly with respect to free tissue transfer and transplantation. In contrast, a number of techniques have ancient origins that have been refined over the years. Many defects will have multiple reconstructive options and a number of factors require consideration to decide which are appropriate for an individual patient. In this chapter anatomical units of the oral cavity (lip, cheek, tongue, floor of mouth and palate), and face (forehead, orbit, nose, cheek and ear) are considered in turn, with reconstructive options presented from simple to complex.

Résumé :
In 1935, Einstein and Rosen described what is now called the Einstein-Rosen bridge. Wheeler called this a wormhole, which could connect two distant parts of the universe. Thorne and Morris showed the wormhole cannot be traversable unless exotic matter with negative energy props it up. Using the Penrose mechanism of superradiance, one can produce rotational energy from a black hole, which could be used to detect dark matter particles. Higher dimensional objects such as branes in superstring theory have been considered as sources of gravitational waves. Black holes have even been proposed to be giant atoms, related to Hawking radiation and black hole entropy. Bekenstein and Mukhanov postulated that black holes radiated quantum radiation. Many such speculative ideas have been put forth that could potentially be verified by detecting gravitational waves. Yet, many physicists work with mathematical equations, unconcerned with whether their ideas can be verified or falsified by experiments.

Résumé :
Morris, King, and Frady were journalists, all born in the South, who came of age in the 1950’s and began their careers on Southern daily newspapers. John Grammer traces how they came together during Morris’s brief but momentous editorship of Harper’s magazine from 1967 to 1971, with King and Frady among his most important contributors. The owners of the magazine called these young southerners “the wrecking crew” because of their raucous, often alcohol-fueled irreverence toward many conventions but particularly toward those of journalism. Like such contemporaries as Norman Mailer, Tom Wolfe, and Joan Didion, they tested the border between fiction and journalism with deeply reported articles that read like short stories. They were led to these innovations in part by their admiration for literary elders like William Faulkner, Robert Penn Warren, and Thomas Wolfe. But they put this literary inheritance to a new purpose when, as young reporters, they encountered the Civil Rights Movement in the South. As “who-what-when-where” journalism proved inadequate to the unique pressures of the moment, they improvised a literary method and created an important but heretofore under-recognized chapter in the literary history of the South.

It considers Badius’s ideas about the links between poetry and moral instruction alongside those of contemporary writers Jacob Wimpfeling and Battista Spagnoli (Mantuan). Badius saw all of his familiar commentary texts as providing moral instruction in some sense. The chapter examines in particular Badius’s prefaces, prologues and commentaries on Roman satire (Horace, Juvenal and Persius) and Roman comedy (Terence); and his two adaptations of the Ship of Fools.

Résumé :
This chapter elaborates one of the first true medical fads to sweep the literary scene of post-revolutionary France: physiognomy, or as its practitioners called it, the art and science of seeing. With this term, the chapter shows how one could divine a person's thoughts, intentions, and inner character by studying comportment, gestures, and other physical ticks, especially those made by the human face. The chapter explains how historians have identified physiognomy as a critical link in the story of European racism. It captures ongoing concerns within physiognomic discourse, then describes why physiognomic writings swept such a wide breadth of French intellectual life after the Reign of Terror. The chapter explores the factors why physiognomy appealed to many different political, social, and intellectual figures in the post-revolutionary period. It highlights physiognomy's defining features: its ideological and philosophical malleability, then argues that physiognomy fit into the growing world of medical writing, genres, and subcultures in the post-revolutionary years.

Résumé :
Abstract Fear of death and the unknown can overwhelm us: sending us into a state that Søren Kierkegaard called dread. One place to look for more positive counter-narratives is the genre of fantasy. Fantasy frequently invokes fear, yet it also offers ways of incorporating and managing fear so that it doesn’t become paralyzing or an excuse for violence. Fantasy borrows from fairy tale what Tolkien called eucatastrophe, the “sudden and miraculous grace” that takes us from despair to joy. This chapter explores some of the ways fantasy handles great fear, with examples ranging from the folk tale about “The Boy Who Went Forth to Learn Fear” to Ursula K. Le Guin’s Earthsea stories. The most successful strategies are those that show us how to name and face our fears by giving them our own names and faces.

Texte intégral
Résumé :
In this paper, a general workflow for the global Sensitivity Analysis (SA) has been proposed based on the coupling of VUQ toolkit DAKOTA and Multiphase Computational Fluid Dynamics (MCFD) solver boilEulerFoam. A surrogate model is first constructed based on sampling simulations from boilEulerFoam. This surrogate is based on Gaussian Processes Model (GPM) and is validated and proved to have good properties. The Morris Screening method is then applied based on the surrogate to those interfacial momentum closure terms for SA, including drag, lift, turbulent dispersion, wall lubrication, and virtual mass. Two different cases are considered, one is on low-pressure adiabatic flow, and the other is on high pressure boiling flow. Each case has its experimental background with data support. The radial void fraction distribution, gas velocity, relative velocity and liquid temperature (only for high pressure boiling case) are chosen as the Quantities of Interest (QoIs) which are of key interests for two-phase flow simulation and boiling crisis prediction. The interfacial force coefficient of each closure term is chosen as the input parameter. For the boiling case, the bubble diameter effect is also analyzed. Three remarks are drawn from this work on SA. First, it demonstrates the feasibility of surrogate model in the VUQ work for models in MCFD solver. The computational cost can be significantly reduced by employing the surrogate model. Secondly, through the Morris Sensitivity measurements, the importance of interfacial forces on different QoIs and regions can be analyzed and ranked for the two cases. Such analysis is also helpful for further model parameter calibration. Last but not least, the limitation of current work and the desired future work are discussed.

Résumé :
To investigate the crack failure of a certain turbine disc mortise, a test system with a new low- and high-cycle non-interfering loading scheme was established to study the Low- and High-Cycle Combined Fatigue (L-HCCF) of fir-tree mortise at elevated temperature. Then, for 50Hz and 100Hz vibrations with constant stress amplitude superimposed on the same low cycle loading respectively, the contrast L-HCCF life tests of light- and serious-corrosive disc mortises were carried out. Through real-time crack detection of the first teeth, the crack propagation rule of fir-tree mortise, a typical multiple load path structure, was obtained. Finally, a new method, two-frequency-ratio method, was presented to relate the load and life of laboratory test to the equivalent those of service in order to help the definition of the failure criteria for serious-corrosive discs in actual practice. The extrapolative results show that the life policies in use for light-corrosive turbine disc can not applied to serious-corrosive disc directly because its reliable life is greatly less than an overhaul schedule, and it is urgent to establish criteria for withdrawal from service of the serious-corrosive discs so as to assure the structural integrity of this aeroengine.

Résumé :
The periodization of fine and applied art after the industrial revolution and the response of alienated artists to industrial kitsch testifies to the utility and purpose of art—the artistic and social avantgardes and the crown of all their endeavors in the heroic period. From art and craft pastiche, to utopian efforts to reform society through design, a rich linear syntagm was structured that intrigued and burdened the creatives from this region, who sought to introduce the land of peasants and barbarogens into the currents of industrial and social progress, culture and art. One of those individuals, in whom Morris and Marinetti, Van Doesburg and Itten, Gropius and Meyer, Vassarelli and Dibiffe... Müller-Brockman and Rand conflicted, tirelessly pursued the affirmation and institutionalization of applied art and design through pedagogical, editorial, theoretical and research work, as well as visual and graphic practice. Miodrag Miša Nedeljković was a modernist with a small 'm', artist and designer, theoretician and practitioner, who nomadically moved through the currents of modern and postmodern fine and applied art and design with renaissance curiosity, driven by intrigue and logic, was primarily concerned with the emergence and establishment of circumstances, and environmental issues.

Day, W. David. « Limits on Morrow Mean Stress Correction of Manson-Coffin Life Prediction Models ». Dans ASME 2011 Turbo Expo : Turbine Technical Conference and Exposition. ASMEDC, 2011. http://dx.doi.org/10.1115/gt2011-45444.

Texte intégral
Résumé :
Accurate prediction of crack initiation life is of critical importance in designing turbo-machinery. To improve this accuracy, more sophisticated prediction techniques are required. A large number of materials have shown a correlation between low cycle fatigue initiation life and strain range, as represented by the well-known Manson-Coffin equation. Testing has shown that tensile mean stress has a negative impact on life. This effect has been noted for many years when applied to high-cycle fatigue, resulting in the use of Goodman or Haigh diagrams to account for the impact of both stress range (and therefore strain range) and mean stress. Morrow proposed a methodology for accounting for mean stress in low cycle fatigue. Noting that as plasticity increases, the effect of mean stress decreases, the correction was applied only to the elastic strain versus life line. Use of the Morrow mean stress corrections improves the accuracy of life predictions, but there are limitations. The most significant of these limitations are situations in which the correction may be non conservative for high compressive mean stresses or very high tensile mean stresses. While a benefit from compressive mean stress is to be expected, at some point further increasing the compressive mean stress should have a negative impact on life. At very high tensile mean stresses near the material yield, the calculated impact of mean stress on life is non conservative. To overcome these limitations, the analyst may place limits on the acceptable range of R-ratios used based on actual test data, but this would do little more than highlight when the user is outside of his database limits. Alternatively a life system may be made in which mean stresses are conservatively expected to be tensile. Neither of these methods are useful for calculating different lives in compressive or tensile regimes. This difficulty is especially seen in bolted joints, which are subjected to high mean stresses and small stress amplitudes. A technique is proposed here in-which limits are placed on the mean stress correction, directly analogous to those used in the creation of so-called modified Goodman diagrams. This technique has been successfully applied at PSM to improve the accuracy of life prediction without increasing the risk of non conservatism. A review of some literature is made to show examples where this effect may be taking place. A small number of tests provide additional validation.

Résumé :
A fully automated centrifugal analyser (ACL, Instrumentation Laboratory, Milan, Italy) specifically designed for hemostasis tests was evaluated for its performance of methods based on clot detection by light scattering measurement or on splitting of chromogenic substrates.In general ACL performed at least as precisely as the comparative methods.PT,APTT,factor VIII and factor VII values obtained by ACL using reagents recommended by the manufacturer were correlated with those obtained by a semiautomated coagulometer (Coag A Mate X2, General Diagnostics, Morris Plains, N.J.) using reagents routinely employed in our laboratory.ACL was compatible with a widely used commercial APTT reagent (Automated APTT,General Diagnostics) both for APTT and factor VIII,whereas it was not so with Manchester Comparative Reagent,being fully compatible for factor VII but not for PT.Fibrinogen results obtained during the performance of PT by ACL,were correlated with those obtained by the standard clotting method performed with an electromechanical coagulometer,however a discrepant result was obtained in plasma from a patient with dysfibrinogenemia.Antithrombin and plasminogen results obtained by ACL using reagents supplied by the manufacturer were correlated with those obtained with other commercial reagents and standard photometric methods. In conclusion ACL presents features such as high output, easy operability, high precision and large panel of clotting and chromogenic assays which makes it suitable to cope with the large work load of the routine coagulation laboratory.Its incompatibility to accept some reagents together with the need to follow strictly the specified operational parameters (e.g. quantity of plasma and reagents and incubation time) makes it rather rigid for adaptation to research specifications.

Résumé :
Hosts of small start up companies and private institutions have become and are being enamored with the apparent feasibility of readily converting small turbochargers (T/C’s) into low cost microturbines. Turbocharger to micro turbine convertibility has indeed been demonstrated primarily motivated as an opening bid to gain recognized credentials into the potentially huge small turbogenerator commercial market. It is coincidently opportune that advanced technology development of the small T/C with a single stage centrifugal compressor and single stage radial inflow turbine is currently under going a meta-morphis in order to satisfy green environment mandated automobile fuel economy and emissions goals. The similarity of the T/C to the conventionally adopted microturbine configuration with radial compressor and turbine components plus undergoing T/C technology advancement entices the virtues of low manufacturing cost attributes associated with the millions of T/Cs that are produced annually. This paper examines the viability of these converted T/C efforts in attempting to penetrate the small gas turbine market, versus those more specially developed, albeit more costly units, already being marketed by established microturbine manufacturers.

Texte intégral
Résumé :
We present an iterative method to solve static piping analysis including Coulomb friction between pipes and supports. It is known that the most stable method to find the solution of this problem is to look for the correct stiffness to add in the plane orthogonal to the direction of the restraints for the resulting forces to be of correct intensity. The naivest way to pick the stiffnesses at each step is to choose the ones that would give the correct forces intensities if the displacements were correct. It is very effective in term of precision, but sometimes slow in term of execution. The penalty comes from the fact that the stiffness matrix is different at each iteration and thus that it must be factorized again. In this article we propose a way to increase the speed of convergence: selecting a subset of supports among the ones where convergence is the worst, and introducing sub-iterations focusing only on those supports can reduce the number of main iterations. Those sub-iterations can be calculated at a much lesser cost than the main ones by using the generalized Sherman-Morrison formula. This algorithm was successfully implemented into the piping analysis software PIPESTRESS version 3.9.1 developed by DST Computer Services SA (the version number is temporary, the release date is Q3/Q4 of 2018).

Established as a personal right, the right to free speech implies obligations and duties, which may generate possible restrictions. Freedom of expression works correctly in a legal framework when it comes to a legitimate aim in a state law. Article 10, paragraph 2, of the Convention explains the conditions under which the right to freedom of expression is justified by the need to protect certain public interests (such as those relating to national security, the territorial space of the state, public order, the prevention of crimes, the protection of health and social morals, the guarantee of authority and the impartiality of the judiciary) but also to protect certain private interests, such as reputation and the rights of others. persons or the need to prevent the publication of secret information. This paragraph basically authorizes states to take certain measures to protect those interests, which materialize through rules and normative rules of the right to conscience, opinion and freedom of expression States enjoy a margin of appreciation for establishing the need for such reactions in a state governed by the rule of law, but in the end it is also up to the European Court of Human Rights to rule on the compatibility of interference with the provisions of the Convention, assessing on a case-by-case basis if the interference arises as a result of the urgent social issues and whether it is fair.

Résumé :
Since Mo Yan received the Nobel prize and also because he said many times that he considers Pu Songling his teacher, and he on more than one occasion reiterated that he was heavily influenced by Liao Zhai zhi yi, literary connections between Mo Yan and Pu Songling have been discussed by many literary scholars and critics. However, when it comes to contemporary literati, the scope of writers influenced by Liao Zhai zhi yi and those who revere this masterpiece is in no way limited by Mo Yan only. In such dimensions as literary style, approach to subject selection, character depiction and others, Liao Zhai zhi yi in one way or another exerted an influence over other writers. This paper deals with the influence exerted by Liao Zhai zhi yi on the linguistic consciousness, moral concepts and character depiction in contemporary Chinese literature, using Sun Li, Wang Zengqi and Gao Xiaosheng as examples. The clear and polished writing of Liao Zhai zhi yi, being exquisitely melodic throughout, the praise it gives to the persons who put morals and friendship before material possessions and are unwilling to forgo them even faced with the choice between life and death as well as the depiction of female characters — all of this served as an example and an inspiration for Sun Li, Wang Zengqi and Gao Xiaosheng.

Résumé :
Improving plant cell wall (fiber) degradation remains one of the highest priority research goals for all ruminant enterprises dependent on forages, hay, silage, or other fibrous byproducts as energy sources, because it governs the provision of energy-yielding nutrients to the host animal. Although the predominant species of microbes responsible for ruminal fiber degradation are culturable, the enzymology and genetics underpinning the process are poorly defined. In that context, there were two broad objectives for this proposal. The first objective was to identify the key cellulosomal components in Ruminococcus albus and to characterize their structural features as well as regulation of their expression, in response to polysaccharides and (or) P AA/PPA. The second objective was to evaluate the similarities in the structure and architecture of cellulosomal components between R. albus and other ruminal and non-ruminal cellulolytic bacteria. The cooperation among the investigators resulted in the identification of two glycoside hydrolases rate-limiting to cellulose degradation by Ruminococcus albus (Cel48A and CeI9B) and our demonstration that these enzymes possess a novel modular architecture specific to this bacterium (Devillard et al. 2004). We have now shown that the novel X-domains in Cel48A and Cel9B represent a new type of carbohydrate binding module, and the enzymes are not part of a ceiluiosome-like complex (CBM37, Xu et al. 2004). Both Cel48A and Cel9B are conditionally expressed in response to P AA/PPA, explaining why cellulose degradation in this bacterium is affected by the availability of these compounds, but additional studies have shown for the first time that neither PAA nor PPA influence xylan degradation by R. albus (Reveneau et al. 2003). Additionally, the R. albus genome sequencing project, led by the PI. Morrison, has supported our identification of many dockerin containing proteins. However, the identification of gene(s) encoding a scaffoldin has been more elusive, and recombinant proteins encoding candidate cohesin modules are now being used in Israel to verify the existence of dockerin-cohesin interactions and cellulosome production by R. albus. The Israeli partners have also conducted virtually all of the studies specific to the second Objective of the proposal. Comparative blotting studies have been conducted using specific antibodies prepare against purified recombinant cohesins and X-domains, derived from cellulosomal scaffoldins of R. flavefaciens 17, a Clostridium thermocellum mutant-preabsorbed antibody preparation, or against CbpC (fimbrial protein) of R. albus 8. The data also suggest that additional cellulolytic bacteria including Fibrobacter succinogenes S85, F. intestinalis DR7 and Butyrivibrio fibrisolvens Dl may also employ cellulosomal modules similar to those of R. flavefaciens 17. Collectively, our work during the grant period has shown that R. albus and other ruminal bacteria employ several novel mechanisms for their adhesion to plant surfaces, and produce both cellulosomal and non-cellulosomal forms of glycoside hydrolases underpinning plant fiber degradation. These improvements in our mechanistic understanding of bacterial adhesion and enzyme regulation now offers the potential to: i) optimize ruminal and hindgut conditions by dietary additives to maximize fiber degradation (e.g. by the addition of select enzymes or PAA/PPA); ii) identify plant-borne influences on adhesion and fiber-degradation, which might be overcome (or improved) by conventional breeding or transgenic plant technologies and; iii) engineer or select microbes with improved adhesion capabilities, cellulosome assembly and fiber degradation. The potential benefits associated with this research proposal are likely to be realized in the medium term (5-10 years).
