International Conference on Theoretical Physics

International Conference on Theoretical Physics

Auteure: Daniel Iagolnitzer , Vincent Rivasseau , Jean Zinn-justin

Nombre de pages: 984

The International Conference on Theoretical Physics, TH-2002, took place in Paris from July 22 to 27 in the Conference Center of the UNESCO, the United Nations Educational Scientific and Cultural Organization, under aegis of the IUPAP, the International Union of Pure and Applied Physics and of the French and Euro pean Physical Societies, with a large support of several French, European and international Institutions. International and crossdisciplinary, TH-2002 welcomed around 1200 partic ipants representing all domains of modern theoretical physics. The conference offered a high-level scientific program, including 18 plenary lectures, 45 general lectures in thematic sessions and 140 more specialized lectures, partly invited and partly selected among proposals received from participants. Around 500 contribu tions were also presented as posters. Plenary lectures as well as general thematic lectures were addressed to a general audience of theoricians, not only to specialists. According to our commitments towards UNESCO and other sponsoring insti tutions, TH-2002 attributed more than 200 fellowships, mostly to scientists from developing countries and Eastern Europe, covering...

The Significance of Zoochromes

The Significance of Zoochromes

Auteure: A.e. Needham

Nombre de pages: 432

As the title indicates, the theme of this book is the functions of biochromes in animals. Recent works on zoochromes, such as those of D. L. Fox (1953), H. M. Fox and VEVERS (1960) and VUILLAUME (1969), have been concerned primarily with the chemical nature and the taxonomic distribution of these materials, and although function has been considered where relevant this has not been the centre of interest and certainly not the basis for the arrangement of the subject matter. Functional significance is a profitable focus of interest, since it is the one theme which can make biochromatology a discrete and integral subject, and because it is the main interest in all biological fields. At present chromatology seems to be a particularly schizoid subject since it is clear that in metabolic functions biochromes are acting in a chemical capacity whereas integumental pigments function mainly biophysically, in neurological and behavioural contexts. It is profitable to attempt an integration by studying the functions of as many chromes as possible, from all aspects.

Feeling and Value, Willing and Action

Feeling and Value, Willing and Action

Auteure: Marta Ubiali , Maren Wehrle

Nombre de pages: 291

This volume explores the role and status of phenomena such as feelings, values, willing, and action in the domain of perception and (social) cognition, as well as the way in which they are related. In its exploration, the book takes Husserl’s lifelong project Studien zur Struktur des Bewusstseins (1909-1930) as its point of departure, and investigates these phenomena with Husserl but also beyond Husserl. Divided into two parts, the volume brings together essays that address the topics from different phenomenological, philosophical, and psychological perspectives. They discuss Husserl’s position in dialogue with historical and recent philosophical and psychological debates and develop phenomenological accounts and descriptions with the help of Geiger, Heidegger, Merleau-Ponty, Plessner, Sartre, Scheler, Schopenhauer, and Reinach.

I Prezzi Delle Cose Nell'età Preindustriale

I Prezzi Delle Cose Nell'età Preindustriale

Auteure: Istituto Internazionale Di Storia Economica F. Datini. Settimana Di Studio

Nombre de pages: 434

La dinamica dei prezzi è uno degli argomenti classici della storia economica. L'attenzione per questo tema fu particolarmente viva a partire dagli anni trenta del novecento, in tutti i paesi europei. I materiali raccolti e pubblicati a quell'epoca continuano a costituire una base documentaria importante per ogni ricerca sull'andamento economico delle economie pre-industriali. L'interesse per i prezzi si ridusse dagli anni settanta agli anni novanta. È ripreso, tuttavia, negli ultimi quindici-venti anni come conseguenza della rinnovata attenzione per il tema della crescita e per i cambiamenti di lungo periodo nelle economie del passato. Il confronto fra i livelli di sviluppo di economie diverse, come quella europea e quella asiatica, insieme con l'uso di strumenti statistici più avanzati nel campo della storia economica, ha rafforzato l'interesse per i prezzi. I contributi presenti in questo volume si articolano intorno a due macro-temi: La formazione dei prezzi nelle economie e società pre-industriali durante i secoli dal XII all'inizio del XIX e il movimento dei prezzi nel lungo periodo, nonché il rapporto esistente con quello di altre variabili economiche e non-economiche,...

107 In this way the absolute values of the structure factors may be found, not the phases (6. 8). The problem to find these phases is the phase problem. The present article will treat the following topics. At first the description of the ideal crystal will be given in Chap. B. The underlying principles of this description are the concepts of reciprocal lattice, FOURIER synthesis and sym metry. The evaluation of the intensity will then follow in Chap. C and D. Chap. E is concerned with the phase problem and related topics. Though this article treats the analysis of crystal structures, the fundamental concepts for other structures will here be found too. But these topics, and the experimental methods, will l find their place elsewhere . B. Description of the crystalline state. I. Lattice theory. a) The direct lattice. 8. Introduction. In Sect. 3, a description of the ideal crystal was given: The space, occupied by a crystal, is divided into congruent parallelepipeds, each with the same orientation. This parallelepiped is defined by the three basic vectors, a, band c, drawn from an origin 0 (Fig. 2), and is called the primitive cell. This cell is filled with atoms (or ions), and the...

Auteure: Vincent Rivasseau

Nombre de pages: 344

The Poincaré Seminar is held twice a year at the Institut Henri Poincaré in Paris. This volume contains the lectures of the 2002 seminars. The main topic of the first one was the vacuum energy, in particular the Casimir effect and the nature of the cosmological constant. The second one concentrated on renormalization, giving a comprehensive account of its mathematical structure and applications to high energy physics, statistical mechanics and classical mechanics. Students will find excellent introductions to the subjects with further lectures leading to the frontiers of experimental and theoretical research, scientists will profit from contributions by outstanding experts.

Protection Des Minorités Nationales Par Leur Etat-parent

Protection Des Minorités Nationales Par Leur Etat-parent

Auteure: European Commission For Democracy Through Law

Nombre de pages: 432

This report contains a number of papers which examine the national laws of European countries regarding the treatment and protection of people belonging to national minorities who live in states outside the borders of their country of origin. This study was undertaken in order to establish whether such laws are compatible with the principles of international law and Council of Europe standards, following the adoption by Hungary in 2001 of an Act which provides benefits and assistance to those of Hungarian origin or identity who live in neighbouring countries.

Phenomenology on Kant, German Idealism, Hermeneutics and Logic

Phenomenology on Kant, German Idealism, Hermeneutics and Logic

Auteure: Thomas M. Seebohm

Nombre de pages: 366

This volume comprises systematic as well as historical essays, including contributions intended to give comprehensive overviews of such areas as genetic phenomenology, transcendental phenomenology, philosophy and history of logic and mathematics, Kant, hermeneutics, Hegel, and philosophy of language. The book is addressed to phenomenologists, particularly those who are interested in some or all of the areas mentioned. In his introduction Joseph J. Kockelmans indicates that these diverse areas enter into dialogue in the work of Thomas M. Seebohm, whom the editors and authors wish to honor, and the systematic papers mirror the state of the art of research in the above-mentioned disciplines.
