Book Description
It has become a tradition in the Union to publish the Invited Discourses and the Proceedings of the Joint Discussions held at a Gene ral Assembly in a separate volume entitled HIGHLIGHTS OF ASTRONOMY. This is the fourth volume of its kind and it contains some of the scientific highlights of the Grenoble General Assembly. In order to reduce its size it was decided to publish its content in two separate parts. The part (I) contains the full texts of the In vited Discourses given by Prof. J.-C. Pecker and by Dr. C. Sagan, and an abstract of Dr. P. Morrison's paper, thus complying with his wish to forego publication of the full text of his Discourse. Furthermore it collects the proceedings of three Joint Discussions and one Joint Meeting all of which are related essentially to observations from space, to external galaxies and to cosmology. Part (n) contains the proceedings of the four Joint Discussions and one Joint Meeting related essentially to stars and the structure of our Galaxy. Clearly Volume 4 (parts I and TI) of the Highlights reflects only a part of the scientific activities which took place at the Grenoble General Assembly. Many more important papers and discussions were held during Commission meetings and joint meetings. They may be found in the Commissions' reports published in the Transactions Vol. XVI B, 1977.

Book Description
This written account of the Symposium on Planetary Nebulae was prepared from manuscripts submitted by the participants. Nearly every paper that was presented at the meeting is reproduced here, in either complete or abbreviated form. The dis cussions have been somewhat shortened and rearranged, but we have tried to preserve the essential points and the general tenor of the exchanges. Participants who spoke in the discussion were asked immediately for written remarks, which were then edited, reproduced, and circulated at the meeting by the highly effective local Secretariat organized by Dr Perek. In addition, notes of the discussion taken by Mrs Edith F. Swan and by the undersigned were used. We wish to thank all the authors for their unusually good cooperation. We are especially grateful to Dr Minkowski, who kindly provided many excellent repro ductions of Mount Wilson and Palomar photographs, mostly taken by himself, of various planetary nebulae. We are particularly indebted to Mrs Swan, who attended the Symposium, made notes on the papers and discussions as they occurred, and did much of the checking and editing of the manuscripts. In addition, we are very grateful to Mrs Evelyn Seaver, who also did much of the checking, editing, and retyping of manuscripts, and to Dr B.L. Webster, Miss Rebecca Todd, Mr Joseph Tapscott, and Mr Dennis Schatz, who provided excellent assistance in the preparation of this volume.

Book Description
Essentials of Modern Physics Applied to the Study of the Infrared covers topics about the essentials of modern physics. The book starts with the situation of research into the infrared and the problems to which it gives rise, and then discusses instrumentation in the infrared: optics, sources, receivers and electronics. The book describes the interaction between the infrared and matter within the framework of Lorentz's general theory and in the particular case of solids using Born's theory and introducing the notion of phonons. The region of the electromagnetic spectrum and the developments in science and industry, including X-ray analysis, molecular beam experiments, radio, and television are considered. The book tackles the sources of infrared as well as infrared detectors. The text will be useful to physicists, engineers, and laboratory technicians.

Book Description
Ces Actes du Colloque XV pour l'etude du dessin sous-jacent et de la technologie dans la peinture (Bruges, 11-13 septembre 2003), reunissent trente-six etudes traitant d'oeuvres d'art flamand, espagnol, portugais, italien et francais. Ces etudes sont suivies, comme dans les Actes precedents, d'une bibliographie de l'infrarouge.Depuis de nombreuses annees on sait que la peinture ancienne est constituee - outre d'oeuvres dites "originales" - de copies, de repliques et de pastiches, produites dans des ateliers actifs qui faisaient appel a des collaborations. Les bases sur lesquelles on avait fonde jadis les catalogues des maitres sont ebranlees. De nombreuses attributions doivent etre revues. Les auteurs du present volume ont porte leur effort dans ce sens, examinant d'un oeil critique le statut des peintures et les indices qui permettent de reconnaitre l'original de la copie. Certains auteurs traitent de procedes de copies, de l'usage de cartons, modeles et papiers perfores, mais egalement de couleurs, d'encres, d'enduits, de technique picturale ... D'autres auteurs tentent de preciser le nombre de collaborateurs dans les ateliers. D'autres encore s'interessent a une methode d'examen, comme la radiographie, pour l'exploiter afin de distinguer au mieux la main du maitre de celle du copiste.

Book Description
Progress in Refrigeration Science and Technology, Volume II is a collection of papers from the Eleventh International Congress of Refrigeration held in Munich in August-September 1963. These papers deal with the various scientific and technical aspects, designs, and technology of refrigeration used in food, as well as advances in air-conditioning, and heat pumps. One paper discusses the refrigeration of meat, fruit, or vegetables, and the reaction rate of proteolysis in low temperatures. The paper points out that meat preservation by freezing is not economical below 60 degrees centigrade citing the reason that cathepsines are still catalytically active in lower temperatures. Other papers discuss the effects of freezing of beef, pork, turkey, chicken, sweet corn, spinach puree. As regards fruit and vegetable storage, the air needs to be purified to inhibit infections, retard fungal or bacterial growth, and dissipate ripening gases or foul odors. Another paper examines the reasons for doing away with floor insulation in refrigeration plants used in storing fresh meat during the summer and winter months. This collection is suitable for engineers in the area of refrigeration, and also for food technologists involved in food research and preservation.

Book Description
Infrared and Millimeter Waves is a series of books that compiles the work of several authors, with each volume focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. Organized into seven chapters, the book discusses topics that are relevant to submillimeter techniques. The first chapter is a review of submillimeter and short millimeter wave-detection techniques. The next chapter covers the optimization of Schottky-barrier diodes, and the following chapter covers pyroelectricity. The fourth chapter covers photon drag, while the fifth chapter covers electrically excited submillimeter-wave lasers. The sixth and seventh chapters discuss submillimeter magneto spectroscopy and cyclotron resonance, respectively. This book will be of great use to researchers and professionals whose work involves infrared and millimeter waves.

Book Description
Lattice Dynamics covers the proceedings of the 1963 International Conference on Lattice Dynamics, held at the H.C. Ørsted Institute of the University of Copenhagen on August 5-9. This book is composed of seven parts that focus on a better fundamental understanding of the interactions between atoms in solids and their role in lattice dynamics. The major topics covered include phonon dispersion curves, anharmonic effects, optical and dielectric effects, influence of defects on lattice vibrations, elasticity, and developments. Papers on the study of vibrational spectra by infrared absorption, X-ray and neutron scattering and the electron tunneling effects as well as papers on the influence of defects and on a variety of other problems in lattice dynamics are included. This book will prove useful to applied physicists and researchers in the field and related fields of lattice dynamics.
