Abstract

The Göttingen Observatory, workplace of the famous scholar Carl Friedrich Gauss, is an important architectural monument. In 2005, it has been reconstructed jointly by the Georg-August-University and the Academy of Sciences in Göttingen. Since then it serves as a representative building for the University and is the seat of the Academy. With the use of the historic rooms for exhibitions this imposing building is open to the public for the first time. 200 years ago the observatory represented the recent scientific findings of its time and moved the University of Göttingen into the leading group of the foremost research institutions in Europe at this time. Also due to its architecture it has been a big leap for Georg Heinrich Borheck, architecture of the University of Göttingen. The war of the Napoleonic era disrupted the attempt of Borheck to publish his description of the construction of the Göttingen observatory in 1805. But his writing is still relevant today and will be finally published with this band for the first time accessible to a wide public. It shows the principles on which public buildings were designed then, explains the importance of the construction in art- and science-historical perspectives and informs on the plans for the restoration of the observatory in a separate article and in the preface by the President of the Georg-August University Prof. Dr. Dr. hc Kurt von Figura.

Abstract

The third edition of this indispensable book in radio interferometry provides extensive updates to the second edition, including results and technical advances from the past decade; discussion of arrays that now span the full range of the radio part of the electromagnetic spectrum observable from the ground, 10 MHz to 1 THz; an analysis of factors that affect array speed; and an expanded discussion of digital signal-processing techniques and of scintillation phenomena and the effects of atmospheric water vapor on image distortion, among many other topics.With its comprehensiveness and detailed exposition of all aspects of the theory and practice of radio interferometry and synthesis imaging, this book has established itself as a standard reference in the field. It begins with an overview of the basic principles of radio astronomy, a short history of the development of radio interferometry, and an elementary discussion of the operation of an interferometer. From this foundation, it delves into the underlying relationships of interferometry, sets forth the coordinate systems and parameters to describe synthesis imaging, and examines configurations of antennas for multielement synthesis arrays. Various aspects of the design and response of receiving systems are discussed, as well as the special requirements of very-long-baseline interferometry (VLBI), image reconstruction, and recent developments in image enhancement techniques and astrometric observations. Also discussed are propagation effects in the media between the source and the observer, and radio interference, factors that limit performance. Related techniques are introduced, including intensity interferometry, optical interferometry, lunar occultations, tracking of satellites in Earth orbit, interferometry for remote Earth sensing, and holographic measurements of antenna surfaces. This book will benefit anyone who is interested in radio interferometry techniques for astronomy, astrometry, geodesy, or electrical engineering.

Abstract

This thesis studies the development of LEKID arrays for the use in a mm-wave camera for the IRAM 30m telescope. This includes the design and fabrication of the superconducting microresonators, the modeling and optimization of the mm-wave coupling to the detector and the characterization of the arrays at low temperatures. The results obtained brought IRAM to test a prototype instrument at the telescope, where first astronomical results have been achieved, which are also presented in this work.

Abstract

This book summarizes the science to be carried out by the upcoming Cherenkov Telescope Array, a major ground-based gamma-ray observatory that will be constructed over the next six to eight years. The major scientific themes, as well as core program of key science projects, have been developed by the CTA Consortium, a collaboration of scientists from many institutions worldwide.CTA will be the major facility in high-energy and very high-energy photon astronomy over the next decade and beyond. CTA will have capabilities well beyond past and present observatories. Thus, CTA's science program is expected to be rich and broad and will complement other major multiwavelength and multimessenger facilities. This book is intended to be the primary resource for the science case for CTA and it thus will be of great interest to the broader physics and astronomy communities. The electronic version (e-book) is available in open access.

Abstract

This book consists of a selection of original papers of the leading scientists in the fields of Space and Planetary Physics, Solar and Space Plasma Physics with important contributions to the theory, modeling and experimental techniques of the solar wind exploration. Its purpose is to provide the means for interested readers to become familiar with the current knowledge of the solar wind formation and elemental composition, the interplanetary dynamical evolution and acceleration of the charged plasma particles, and the guiding magnetic field that connects to the magnetospheric field lines and adjusts the effects of the solar wind on Earth. I am convinced that most of the research scientists actively working in these fields will find in this book many new and interesting ideas.

Abstract

Lunar science is in the middle of a small revolution, with now many new countries sending orbiters, landers, and even sample return missions to the moon. Additionally, both governments and private companies are now more and more considering the moon as a base for solar system exploration. With such an increase in attention, lunar science is now encompassing several unified dimensions. The first is the science of the moon itself, its origin, evolution, and inner composition. The second is how humans can live on the moon, covering biology and in general the logistics of surviving there, including surface mapping and in-situ resource utilization.

Abstract

Since the dawn of humanity, people have developed concepts about themselves and the natural world in which they live. This volume aims at investigating the construction and transfer of such concepts between and within various ancient and medieval cultures. The single contributions try to answer questions concerning the sources of knowledge, the strategies of transfer and legitimation as well as the conceptual changes over time and space. After a comprehensive introduction, the volume is divided into three parts: The contributions of the first section treat various theoretical and methodological aspects. Two additional thematic sections deal with a special field of knowledge, i.e. concepts of the moon and of the end of the world in fire.

Abstract

This book presents the semidiplomatic and interpretive issues of the most extensive work which houses the codex 142 of the Arquivo Distrital de Braga, corresponding to its second part, which starts calling itself Remedios varios, e Receitas Approvadas, but also includes, for the end, a copy of the well known and ancient calendaries, or fastos, distributing for each month of the year the recommendations about what to do for the maintenance of the good health, on the one hand, and about the agriculture of each month, of the other, and yet a long line of Several Secrets, with domestic revenues and advice, culinary, agricultural, veterinary, botanical, technic, and even magic and religious (healing prayers, etc.). Conceived as a treaty, it shows the collection of numerous natural remedies, from antiquity to the seventeenth century, mostly dependent on herbs, medicinal plants and trees, available to any person, and even more exotic products such as spices, or swallow nests, that the Discoveries put within reach of Europe by the Portuguese, originating both in Asia and in Africa or in Brazil. Organized by disease or also either by body parts, medicinal herbs and other ingredients, the manuscript highlights a prevalently preventive medicine and is not limited reductively to therapeutic medicine. In all the codex, and in many of the remedies, diet is key, and this is not a restrictive diet for patients, but of very specific and abundant dietary recommendations to maintain health in a much more timely and holistic perspective. The reader may find constant and rich cross-references between this part II of Codex 142 of remedies, the first part, of cooking recipes, already edited, and the third, about agriculture, with valuable and unique recipes and recommendations from de fields of agriculture, pecuary, veterinary and ecological animal husbandry. Despite the specificity of each part, the information, thorough and from a knowledgeable hand, reveals itself through the three notebooks repeated under different facets, complementary, forming an essential triptych to life: nourishment, health, agricultural and veterinary activity in perfect balance with nature and man.
