Comets are small bodies, but of great cosmic relevance. Given its pristine nature, they may preserve valuable and unique information on thechemical and physical processes that took place in theearly solar system, and that may be occurring in the formation of other planetary systems. They might have even played a very important role in the origin of life on Earth. Beyond that, since ancient times comets have inspired awe, superstition, and also curiosity anddebate. Their sudden apparitions challenged the long-held view of the immutability of the heavens, which triggered a long debate on whether comets had a heavenly or terrestrial nature. Therefore, comets have a prominent role in the history...

Minor bodies in the Solar System, though representing only a small fraction of the mass in the Solar System, may well play a fundamental role in terrestrial evolution. This book contains investigations of the dynamics and physics of comets, asteroids and meteor streams, and the rather controversial topic of periodic phenomena in the Solar System as signified by geological records, together with several associated developments in celestial dynamics. All these problems are interwoven. This book makes a contribution towards unravelling the nature of the interactions between the Earth and its celestial environment.
An encyclopedia of Tennessee genealogy, Acklen's "Bible Records and Marriage Bonds" is one of the foremost Tennessee source-books in print. It consists almost entirely of records of births, marriages, and deaths, plus marriage licenses of Dickson, Knox, Lebanon, and Wilson counties. Sections devoted exclusively to marriages generally run chronologically, giving exact dates and full names of brides and grooms. The bible records, however, offer the most substantial evidence of family connections and, in the manner of such records, are actually organic family records listing names and dates of birth, marriage, and death through several generations, depending, of course, on the extent to which a particular bible was handed on in the family and kept up to date. The work is complemented by a surname index of nearly 15,000 entries.
The XXth General Assembly of the International Astronomical Union was held in Baltimore, Maryland USA from August 02 to 11, 1988. The Inaugural Ceremony on August 02 was held in the presence of representatives of the United States Governn:ent, t~e S~ate of Maryland, the City of Baltimore and the host institution -the Johns Hopkins Umverslty- as well as of the National and Local Organising Committees. The scientific programme maintained the high standards of the Union and the scientific proceedings may be found either in this volume or in volume 8 of Highlights of Astronomy. The scientific programme was organised by the 40 Commission Presidents and coordinated by the General Secretary (1985-1988), Dr. J.-P. Swings. The local arrangements were effectively made through the National Organising Committee under the Chairmanship of Prof. F. Drake and the Local Organising Committee under the co-Chairmanship of Prof. A. Oavidsen and Dr. R. Giacconi. The smooth day to day operation of the meeting resulted from the incomparable dedication of Karen Weinstock and Harold Screen.
IAU Transactions are published as a volume corresponding to each General Assembly. Volume A is produced prior to the Assembly and contains Reports on Astronomy, prepared by each Commission President. The intention is to summarize the astronomical results that have affected the work of the Commission since the production of the previous Reports up to a time which is about one year prior to the General Assembly. Volume B is produced after the Assembly and contains accounts of Commission Meetings which were held, together with other material. The reports included in the present volume range from outline summaries to lengthy compilations and references. Most reports are in English.
This book addresses Epigenetics in Cancer and covers the most recent advances in RNA/histone/DNA epigenetics in Oncology. RNA/histone/DNA epigenetics have been shown to play pivotal roles in cancer initiation, progression, maintenance and drug response/resistance, tumor microenvironment, cancer stem cell self-renewal, cancer metabolism, and tumor immune evasion. In particular, research in RNA cancer epigenetics has made impressive progress in the last few years. Individual chapters in Part I (focusing on RNA epigenetics) are devoted to RNA modifications in Cancer Metabolism and Microenvironment, Cancer Stem Cell Biology, Immune Surveillance, Solid Tumors and Tumor Immunity, and Hematopoietic Malignancies, as well as to RNA editing in Cancer. Chapters in Part II and III of the book focus on histone epigenetics and DNA epigenetics, respectively. By familiarizing readers with the latest developments in this complex and challenging field, the book offers a valuable resource for scientists, graduate students and clinicians alike.
