The widespread tendency in solar physics to divide the solar atmosphere into separate layers and to distinguish phenomena of solar activity from phenomena of the quiet Sun emphasizes the wide ranging diversity of physical conditions and events occurring in the solar atmosphere. This diversity spans the range from a neutral, essentially quiescent atmosphere to a highly ionized, violently convective atmosphere; from a domain in which magnetic field effects are unimportant to a domain in which the magnetic pressure exceeds the gas pressure, and from a domain in which the particle motions are Maxwellian to a domain in which an appreciable fraction of the particles is accelerated to relativistic energies. It is now widely recognized that the chromosphere and corona have a common origin in the mechanical energy flux generated in the hydrogen convection zone lying beneath the photosphere. Furthermore, magnetic field phenomena appear to be as vital to the structure of th~ quiet Sun as to the active Sun. For these reasons it appears desirable to present a unified treatment of the entire solar atmosphere, both active and quiet, in a single volume. On the other hand, such a treatise must be very long if it is to avoid being superficial, and it is very difficult for a single author to write authoritatively on such a wide range of topics.

Earth System: History and Natural Variability theme is a component of Encyclopedia of Natural Resources Policy and Management, in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Earth System: History and Natural Variability with contributions from distinguished experts in the field, presents a description of the cosmic environment around our planet influencing the Earth in a number of ways through variation of solar energy or meteorite impacts. The structure of the Earth and its rocks, waters and atmosphere is described. The Theme focuses on geological and evolutionary processes through the history of Earth's epochs and biomes since the Early Earth to the Quaternary. The unifying processes between the Earth's life and its rocks, waters and atmosphere are global natural cycles of carbon, sulfur and other elements that connect and influence the rate of geological processes, climate change, biological evolution and human economy. These five volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

This authoritative textbook - the second volume of a comprehensive three-volume course on theoretical astrophysics - deals with stellar physics. Designed to help graduate students and researchers develop an understanding of the key physical processes governing stars and stellar systems, it teaches the fundamentals, and then builds on them to give the reader an in-depth understanding of advanced topics. The book's modular design allows the chapters to be approached individually, yet seamless transitions create a coherent and connected whole. It can be used alone or in conjunction with Volume I, which covers a wide range of astrophysical processes, and the forthcoming Volume III, on galaxies and cosmology. After reviewing the key observational results and nomenclature used in stellar astronomy, the book develops a solid understanding of central concepts including stellar structure and evolution, the physics of stellar remnants, pulsars, binary stars, the sun and planetary systems, interstellar medium and globular clusters. Throughout, the reader's comprehension is developed and tested with more than seventy-five exercises. This indispensable volume provides graduate students with a self-contained introduction to stellar physics, and will allow them to master the material sufficiently to read and engage in research with heightened understanding.

Since 1967, the main scientific events of the General Assemblies of the International Astronomical Union have been published in the separate series, Highlights of Astronomy. The present Volume 11 presents the major scientific presentations made at the XXIIIrd General Assembly, August 18-30, 1997, in Kyoto, Japan. The two volumes (11A+B) contain the texts of the three Invited Discourses as well as the proceedings or extended summaries of the 21 Joint Discussions and two Special Sessions held during the General Assembly.

Started in 1958, Sanathana Sarathi is a monthly magazine devoted to Sathya (Truth), Dharma (Righteousness), Shanti (Peace) and Prema (Love) - the four cardinal principles of Bhagawan Baba's philosophy. It is published from Prasanthi Nilayam (the Abode of Highest Peace) and acts as a mouthpiece of Baba's Ashram as it speaks of the important events that take place in His sacred Abode, besides carrying Divine Messages conveyed through Divine Discourses of Bhagawan Sri Sathya Sai Baba. The word meaning of Sanathana Sarathi is the 'Eternal Charioteer'. It signifies the presence of the Lord in every being as the atma guiding their lives like a charioteer. It implies that he who places his life, the body being likened to a chariot, in an attitude of surrender in the hands of the Lord, will be taken care of by the Lord even as a charioteer would take the occupant of his chariot safely to its destination. The magazine is an instrument to disseminate spiritual knowledge for the moral, physical and mental uplift of humanity without any discrimination as the subject matter discussed therein is always of common interest and of universal appeal. The fifteen Vahinis - streams of sacredness - known as the Vahini Series comprising annotation and interpretation of the Upanishads and other scriptures, Itihasas like the Ramayana, the Bhagavatha and the Mahabharata, and authentic explanations on Dhyana, Dharma, Prema, etc., have been serially published in this magazine as and when they emanated from the Divine pen of Bhagawan Baba. This magazine is published in almost all Indian languages, English and Telugu from Prasanthi Nilayam and others from respective regions. Every year Sanathana Sarathi comes out with a special issue in November commemorating the Divine Birthday. The English and Telugu magazines are posted on the 10th and 23rd respectively, of every month, from Prasanthi Nilayam. This magazine has wide, ever increasing circulation in India as well as abroad, as the study of it brings the reader closer to the philosophy of the Avatar in simple understandable language THUS SPAKE SAI... Discoursing during the launch of Sanathana Sarathi... From this day, our Sanathana Sarathi will lead to victory the cohorts of truth - the Vedas, the Sastras and similar scriptures of all faiths, against the forces of the ego such as injustice, falsehood, immorality and cruelty. This is the reason why it has emerged. This Sarathi will fight in order to establish world prosperity. It is bound to sound the paean of triumph when universal Ananda is achieved.

This volume, together with its two companion volumes, originated in a study commis sioned by the United States National Academy of Sciences on behalf of the National Aeronautics and Space Administration. A committee composed of Tom Holzer, Dimitri Mihalas, Roger Ulrich and myself was asked to prepare a comprehensive review of current knowledge concerning the physics of the Sun. We were fortunate in being able to persuade many distinguished scientists to gather their forces for the preparation of 21 separate chapters covering not only solar physics but also relevant areas of astrophysics and solar-terrestrial relations. It proved necessary to divide the chapters into three separate volumes that cover three different aspects of solar physics. Volumes II and III are concerned with 'The Solar Atmosphere' and with 'Astrophysics and Solar-Terrestrial Relations'. This volume is devoted to 'The Solar Interior', except that the volume begins with one chapter reviewing the contents of all three volumes. Our study of the solar interior includes a review of nuclear, atomic, radiative, hydrodynamic and hydromagnetic processes, together with reviews of three areas of active current investigation: the dynamo mechanism, internal rotation and magnetic fields, and oscillations. The last topic, in particular, has emerged in recent years as one of the most exciting areas of solar research.
