Book excerpt: Ce travail expérimental concerne l'analyse du transfert de chaleur au sem d'un écoulement turbulent d'air humide en présence ou non d'un phénomène de condensation. Pour cela, une soufflerie spécifique a été conçue au sein du laboratoire afin de générer un écoulement d'air contrôlé en vitesse, en température et en teneur en humidité. Cet écoulement traverse un canal d'étude rectangulaire horizontal dont les parois inférieures sont maintenues à température constante. Une première partie des travaux permet de décrire l'écoulement au sein du canal par l'analyse des champs de vitesse PlV moyenne et fluctuante pour différents nombres de Reynolds (Re = 10056 à Re = 55333) et de détailler les régimes dynamiques obtenus. Dans la zone pleinement turbulente, une attention particulière a été portée sur la caractérisation de la sous-couche visqueuse par PlV à haute résolution spatiale. L'analyse fine du profil de température d'air en proche paroi permet d'estimer avec précision le transfert convectif local. Les résultats obtenus sans changement de phase ne montrent pas d'influence de la teneur en humidité sur le flux convectif. Au-delà des résultats en milieu non-saturé, le phénomène de condensation est abordé. La visualisation du dépôt de vapeur d'eau condensée permet d'identifier macroscopiquement les différents régimes de condensation (film, gouttes oumixte). L'analyse fine à échelle locale permet de définir différentes étapes de la condensation : développement par grossissement et par fusion entre plusieurs gouttes, mouvements de frontières après fusion. Cette étude a été menée pour des substrats de nature et de conditions de mouillabilité différentes, ainsi que pour des taux d'humidité absolue variables. Enfin, l'identification de ces étapes est complétée par la quantification de la condensation à partir des mesures de masse condensée. Celles-ci sont exploitées pour estimer les flux de chaleur latente et pour comparer le comportement sur différents substrats.

Available in PDF, EPUB and Kindle. Book excerpt: If the academic field of death studies is a prosperous one, there still seems to be a level of mistrust concerning the capacity of literature to provide socially relevant information about death and to help improve the anthropological understanding of how culture is shaped by the human condition of mortality. Furthermore, the relationship between literature and death tends to be trivialized, in the sense that death representations are interpreted in an over-aestheticized manner. As such, this approach has a propensity to consider death in literature to be significant only for literary studies, and gives rise to certain persistent clichés, such as the power of literature to annihilate death. This volume overcomes such stereotypes, and reveals the great potential of literary studies to provide fresh and accurate ways of interrogating death as a steady and unavoidable human reality and as an ever-continuing socio-cultural construction. The volume brings together researchers from various countries – the USA, the UK, France, Poland, New Zealand, Canada, India, Germany, Greece, and Romania – with different academic backgrounds in fields as diverse as literature, art history, social studies, criminology, musicology, and cultural studies, and provides answers to questions such as: What are the features of death representations in certain literary genres? Is it possible to speak of an homogeneous vision of death in the case of some literary movements? How do writers perceive, imagine, and describe their death through their personal diaries, or how do they metabolize the death of the “significant others” through their writings? To what extent does the literary representation of death refer to the extra-fictional, socio-historically constructed “Death”? Is it moral to represent death in children’s literature? What are the differences and similarities between representing death in literature and death representations in other connected fields? Are metaphors and literary representations of death forms of death denial, or, on the contrary, a more insightful way of capturing the meaning of death?

Book excerpt: Xenakis: His Life in Music is a full-length study of the influential contemporary composer Iannis Xenakis. Following the trajectory of Xenakis’s compositional development, James Harley, who studied with Xenakis, presents the works together with clear explanations of the technical and conceptual innovations that shaped them. Harley examines the relationship between the composer and two early influences: Messiaen and Le Corbusier. Particular attention is paid to analyzing works which were vital to the composer’s creative development, from early, unpublished works to the breakthrough pieces Metastasis and Pithoprakta, through the oft-discussed decade of formalization and the evolving styles of the succeeding three decades.

Available in PDF, EPUB and Kindle. Book excerpt: What Nazism Did to Psychoanalysis explores the impact Nazism had on the evolution of psychoanalysis and tackles the enigma of the transformation of individual hate into mass psychosis and of the autocratic creation of a neo-reality. Addressing the effects of the Holocaust on the psychoanalytic world, this book does not focus on the suffering of the survivors but the analysis of the concrete mechanisms of destruction that affected language and thought, their impact on the practice of psychoanalysis and the defences that psychoanalysts tried to find against the linguistic, legal and symbolic chaos that struck the foundations of reality. Laurence Kahn discusses the struggle against the appropriation, by the Nazi language, of key terms such as demonic nature, drives, ideals and, above all, the Selbsterhaltungstrieb (the self-preservation drive), which became, with Hitler, the axis of the living space policy, the "Lebensraum". Covering key topics such as trauma, transgenerational issues, silence and secrecy and the depredation of culture, this is an essential work for psychoanalysts and anyone wishing to understand how strongly the development of psychoanalysis was affected by Nazism.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, Lawrence J. Brown offers a contemporary perspective on how the mind transforms, and gives meaning to, emotional experience that arises unconsciously in the here-and-now of the clinical hour. Brown surveys the developments in theory and practice that follow from Freud’s original observations and traces this evolution from its conception to contemporary analytic field theory. Brown emphasizes that these unconscious transformational processes occur spontaneously, in the blink of an eye, through the "unconscious work" in which the analyst and patient are engaged. Though unconscious, these processes are accessible and the analyst must train himself to become aware of the subtle ways he is affected by the patient in the clinical moment. By paying attention to one’s reveries, countertransference manifestations and even supposed "wild" or extraneous thoughts, the analyst is able to obtain a glimpse of how his unconscious is transforming the ambient emotions of the session in order to formulate an interpretation. Brown casts a wide theoretical net in his exploration of these transformational processes and builds on the contributions of Freud, Theodor Reik, Bion, Ogden, the Barangers, Cassorla, Civitarese and Ferro. Bion’s theories of alpha function, transformations, dreaming and his clinical emphasis on the present moment are foundational to this book. Brown’s writing is clear and aims to describe the various theoretical ideas as plainly as possible. Detailed clinical material is given in most chapters to illustrate the theoretical perspectives. Brown applies this theory of transformational processes to a variety of topics, including the analyst’s receptivity, countertransference as transformation, the analytic setting, the paintings of J.M.W. Turner, "autistic transformations" and other clinical situations in the analysis of children and adults. Transformational Processes in Clinical Psychoanalysis will be of great interest to all psychoanalysts and psychoanalytic psychotherapists.

Book excerpt: While the use of the analyst’s own reveries in work with patients has increased in recent times, there has been little critical inquiry into its value, and the problems it may lead to. The Analyst's Reveries finds increasing veneration for the analyst’s use of their reveries, while revealing important differences amongst post-Bionians in how reverie is defined and used clinically. Fred Busch ponders if it has been fully recognized that some post-Bionions suggest a new, radical paradigm for what is curative in psychoanalysis. After searching for the roots of the analyst’s use of reverie in Bion’s work and questioning whether in this regard Bion was a Bionian, Busch carefully examines the work of some post-Bionians and finds both convincing ways to think about the usefulness and limitations of the analyst’s use of reverie. He explores questions including: From what part of the mind does a reverie emerge? How does its provenance inform its transformative possibilities? Do we over-generalize in conceptualizing what is unrepresented, with the corresponding problem of false positives? Do dreams equal understanding and what about the generalizability of the co-created reverie? Busch concludes that it is primarily through the analyst’s own associations that the reverie’s potential is revealed, which further helps the analyst distinguish it from many other possibilities, including the analyst’s countertransference. He believes in the importance of converting reveries into verbal interpretations, a controversial point amongst post-Bionians. Busch ends with the difficult task of classifying the analyst’s reveries based on their degree of representation. The Analyst's Reveries will be of great interest to psychoanalysts and psychoanalytic psychotherapists.
