DOWNLOAD EBOOKThis book has been prepared under the auspice of the European Low Gravity Research Association (ELGRA). The main task of ELGRA is to foster the scientific community in Europe and beyond in conducting gravity and space-related research.This publication is dedicated to the science community, and especially to the next generation of scientists and engineers interested in space research and in the means to use Earth to reproduce the space environment. ELGRA provides a comprehensive description of space conditions and the means that have been developed on Earth to perform space environmental and (micro-) gravity related research. .The book covers ground-based research instruments and environments for both life and physical sciences research. It discusses the opportunities and limitations of protocols and instruments to compensate gravity or simulate microgravity, such as clinostats, random positioning machines, levitating magnets, electric fields, vibrations, tail suspension or head down tilt, as well as centrifuges for hyper-g studies. Other space environmental conditions are addressed too, like cosmic radiation or Mars atmospheric and soil properties to be replicated and simulated on Earth. Future long duration of manned missions, personal well-being and crew interaction are major issues dealt with.

DOWNLOAD EBOOKThe 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.

DOWNLOAD EBOOKMost aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

DOWNLOAD EBOOKOnline Communication provides an introduction to both the technologies of the Internet Age and their social implications. This innovative and timely textbook brings together current work in communication, political science, philosophy, popular culture, history, economics, and the humanities to present an examination of the theoretical and critical issues in the study of computer-mediated communication. Continuing the model of the best-selling first edition, authors Andrew F. Wood and Matthew J. Smith introduce computer-mediated communication (CMC) as a subject of academic research as well as a lens through which to examine contemporary trends in society. This second edition of Online Communication covers online identity, mediated relationships, virtual communities, electronic commerce, the digital divide, spaces of resistance, and other topics related to CMC. The text also examines how the Internet has affected contemporary culture and presents the critiques being made to those changes. Special features of the text include: *Hyperlinks--presenting greater detail on topics from the chapter *Ethical Ethical Inquiry--posing questions on the nature of human communication and conduct online *Online Communication and the Law--examining the legal ramifications of CMC issues Advanced undergraduates, graduate students, and researchers interested in the field of computer-mediated communication, as well as those studying issues of technology and culture, will find Online Communication to be an insightful resource for studying the role of technology and mediated communication in today's society.

DOWNLOAD EBOOKBased on the classic History of Broadcasting in the United States, Tube of Plenty represents the fruit of several decades' labor. When Erik Barnouw--premier chronicler of American broadcasting and a participant in the industry for fifty years--first undertook the project of recording its history, many viewed it as a light-weight literary task concerned mainly with "entertainment" trivia. Indeed, trivia such as that found in quiz programs do appear in the book, but Barnouw views them as part of a complex social tapestry that increasingly defines our era. To understand our century, we must fully comprehend the evolution of television and its newest extraordinary offshoots. With this fact in mind, Barnouw's new edition of Tube of Plenty explores the development and impact of the latest dramatic phases of the communications revolution. Since the first publication of this invaluable history of television and how it has shaped, and been shaped by, American culture and society, many significant changes have occurred. Assessing the importance of these developments in a new chapter, Barnouw specifically covers the decline of the three major networks, the expansion of cable and satellite television and film channels such as HBO (Home Box Office), the success of channels catering to special audiences such as ESPN (Entertainment and Sports Programming Network) and MTV (Music Television), and the arrival of VCRs in America's living rooms. He also includes an appendix entitled "questions for a new millennium," which will challenge readers not only to examine the shape of television today, but also to envision its future.
