Book Description
NOUS UTILISONS LE CONTRASTE DE POTENTIEL LORS DE L'ANALYSE DE DEFAILLANCE DE CIRCUITS INTEGRES. CE CONTRASTE RESULTE DE L'OBSERVATION D'UN CIRCUIT INTEGRE EN FONCTIONNEMENT DANS UN MICROSCOPE ELECTRONIQUE A BALAYAGE. LE RELEVE DE TENSIONS CONTINUES EST PERTURBE PAR L'ACCUMULATION DE CHARGES POSITIVES DANS LA COUCHE DE PASSIVATION DES CIRCUITS INTEGRES. L'ANALYSE DE CE PHENOMENE DE CHARGE, MONTRE LES LIMITES DU MODELE DE LA BARRIERE DE POTENTIEL. NOUS AVONS ETABLI UN MODELE ELECTROSTATIQUE BASE SUR LE CALCUL DU CHAMP ELECTRIQUE EN TOUT POINT DE L'ISOLANT ET DE LA CHAMBRE DU MICROSCOPE. PAR SES EFFETS SUR LA TRAJECTOIRE DES ELECTRONS SECONDAIRES, CE CHAMP MODIFIE LE SPECTRE ET LE TAUX DE REEMISSION. LES VALEURS THEORIQUES OBTENUES CORRESPONDENT AUX VALEURS EXPERIMENTALES ET MONTRENT QU'UN CONTRASTE DE POTENTIEL STATIQUE PEUT ETRE RELEVE SI LA COUCHE DE PASSIVATION EST RECOUVERTE D'UNE COUCHE CONDUCTRICE. LE SONT DES SOLUTIONS POSSIBLES POUR ELIMINER CETTE CHARGE, NOUS POUVONS GRAVER LA COUCHE DE PASSIVATION OU LA COUVRIR D'UNE COUCHE ANTISTATIQUE. LA GRAVURE SECHE, MOINS RISQUEE QUE LA GRAVURE PAR VOIE HUMIDE, PEUT INDUIRE DES DERIVES PARAMETRIQUES, FORMER DES TRANCHEES ET GRAVER DES JOINTS DE GRAIN. LE DEPOT DE LIQUIDE PRESENTE UNE FAIBLE REPRODUCTIBILITE, UN EFFET LIMITE DANS LE TEMPS ET UNE POLLUTION DU CIRCUIT. LES DEPOTS DE CARBONE PAR EVAPORATION SONT REPRODUCTIBLES, UNIFORMES ET OPTIMISABLES. ILS N'ALTERENT NI LE CIRCUIT NI SON COMPORTEMENT ELECTRIQUE. ILS NE SONT PAS EFFICACES DANS TOUS LES CAS. A L'AIDE DE TROIS PLANS D'EXPERIENCES, L'ETUDE DES CONSEQUENCES DES TECHNIQUES DE PREPARATION SUR LA SENSIBILITE DU COMPOSANT A L'IRRADIATION CAUSEE PAR LE FAISCEAU D'ELECTRONS PRIMAIRES MONTRE QUE LES CIRCUITS GRAVES SONT LES PLUS SENSIBLES

Book Description
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.

Book Description
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 Description
"Unique synthesis from the French School of psychoanalytical projective methods This unique book synthesizes the work of leading thinkers of the French School of psychoanalytical projective methods in personality assessment. The French School is a direct successor to Rorschach's and Murray's original approaches using the Rorschach Test and the Thematic Apperception Test (TAT). Underlying this method is the idea of the coexistence of conscious and unconscious processes, of opposite instinctual pairs, and of agents that are ruled by conflicts (Freud). Transitional activity is seen as part of an intermediate space, a mediator space, and bearer of messages between the subject and the clinician (Winnicott). This book brings to life the important contributions of the French School, firstly exploring its theories and methods and then its clinical applications. Detailed case studies from different stages of life examine the psychopathology of everyday life with its severe and disabling states of suffering. Contemporary advances in research and clinical work are presented, and the groundbreaking early work of Nina Rausch de Traubenberg, Vica Shentoub, and Rosine Debray are also critically reread and discussed. Clinical tools adapted for clinicians and researchers in the appendices include a useful schema to facilitate the interpretation of the Rorschach and TAT together, a list of latent solicitations for the TAT, and the current version of the TAT Scoring Grid. This book is essential reading for clinical psychologists, psychiatrists, psychotherapists, researchers, and students interested in applying psychoanalytical theory to projective methods"--

Book Description
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.
