Book excerpt: As early as 2030 the Arctic Ocean could lose essentially all of its ice during the warmest months of the year?a radical transformation that would destroy virtually all of the Arctic ecosystems and disrupt or destroy many northern communities, if not many communities along the coastal areas of Earth. Even now concentrations of Greenhouse gases are rising dramatically ? because of mankind's industry as well as human overpopulation leading to the destruction of the cycle of photosynthesis. The human of Earth seems to be leading its own extinction. Has the cycle reached its ?critical mass? and now unable to be reversed? Will popular social efforts such as ?Going Green? help in any way whatsoever at this point in a global evolutionary crisis? In only a few ? perhaps two ? generations of the human race might we know the answers to whether the human race will have a planet capable of sustaining life without ever leaving this world.

Download or read book Population of Superdeformed Bands and Competition with Fission written by and published by . This book was released on 1990 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Average entry points for superdeformed (SD) and normal states have been measured in {sup 191, 192}Hg and in 152Dy. Compared with normal states, the superdeformed states have entry spins (approximately) 10 h higher and internal excitation energies (U = E -- E{sub yrast}) at least 2 MeV lower for the Hg cases and about 8 MeV lower for 152Dy. By comparison with calculated l- distributions of evaporation residues (ER), using CASCADE to compute the fission competition, we find that the initial population of the SD band in 192Hg originates from the tail of the ER spin distribution. 12 refs., 5 figs.

Download or read book Nuclear Reactor Physics written by Weston M. Stacey and published by John Wiley & Sons. This book was released on 2018-02-07 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third, revised edition of this popular textbook and reference, which has been translated into Russian and Chinese, expands the comprehensive and balanced coverage of nuclear reactor physics to include recent advances in understanding of this topic. The first part of the book covers basic reactor physics, including, but not limited to nuclear reaction data, neutron diffusion theory, reactor criticality and dynamics, neutron energy distribution, fuel burnup, reactor types and reactor safety. The second part then deals with such physically and mathematically more advanced topics as neutron transport theory, neutron slowing down, resonance absorption, neutron thermalization, perturbation and variational methods, homogenization, nodal and synthesis methods, and space-time neutron dynamics. For ease of reference, the detailed appendices contain nuclear data, useful mathematical formulas, an overview of special functions as well as introductions to matrix algebra and Laplace transforms. With its focus on conveying the in-depth knowledge needed by advanced student and professional nuclear engineers, this text is ideal for use in numerous courses and for self-study by professionals in basic nuclear reactor physics, advanced nuclear reactor physics, neutron transport theory, nuclear reactor dynamics and stability, nuclear reactor fuel cycle physics and other important topics in the field of nuclear reactor physics.
Download or read book Population of Superdeformed Bands the Competition with Fission and the Barrier Between Normal and Superdeformed States written by and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we report on the entry points leading to superdeformed (SD) as well as normal bands. We find that, compared to normal bands, the entry spins for the SD bands are about 9 {h bar} higher, and the entry excitation energy 1--3 MeV colder. We also conclude that population of the SD bands represents successful competition against fission. SD bands in both the Dy and Hg regions are considered.

Download or read book Nuclear Power written by Stan Openshaw and published by Routledge. This book was released on 2019-03-28 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1986. Nuclear power is now regarded as essential to survival in the twenty-first century. But the safety of nuclear power stations is a highly controversial topic, and where they will be sited is a most vital question. In this independent critique, based on four years of research, Stan Openshaw argues that reactor siting provides a simple means of offering additional, design-independent margins of safety. Reactor siting policies in the UK and USA are examined and it is suggested that UK siting practices need to be updated. The large number of potential alternative sites should be used to devise new planning strategies – strategies which will minimise both the residual health risks from accidents and the danger that a future change in public opinion might lead to calls for the closure of many existing sites on safety grounds.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of one phase of an upper-division course on quantitative ecology, given each year for the past eight at Berkeley. I am most grateful to the students in that course and to many graduate students in the Berkeley Department of Zoology and Colleges of Engineering and Natural Resources whose spirited discussions inspired much of the book's content. I also am deeply grateful to those faculty colleagues with whom, at one time or another, I have shared courses or seminars in ecology or population biology, D.M. Auslander, L. Demetrius, G. Oster, O.H. Paris, F.A. Pitelka, A.M. Schultz, Y. Takahashi, D.B. Tyler, and P. Vogelhut, all of whom contributed substantially to the development of my thinking in those fields, to my Depart mental colleagues E. Polak and A.J. Thomasian, who guided me into the litera ture on numerical methods and stochastic processes, and to the graduate students who at one time or another have worked with me on population-biology projects, L.M. Brodnax, S-P. Chan, A. Elterman, G.C. Ferrell, D. Green, C. Hayashi, K-L. Lee, W.F. Martin Jr., D. May, J. Stamnes, G.E. Swanson, and I. Weeks, who, together, undoubtedly provided me with the greatest inspiration. I am indebted to the copy-editing and production staff of Springer-Verlag, especially to Ms. M. Muzeniek, for their diligence and skill, and to Mrs. Alice Peters, biomathematics editor, for her patience.

Book excerpt: Group living is a social strategy adopted by many species, where individuals can exhibit long-term social affiliation with others, strengthened through cooperative behaviour and often kinship. For highly social mammals, changes in group membership may have significant consequences for the long-term viability and functioning of a population. Detecting significant social events is essential for monitoring the social dynamics of such populations and is crucial to determining the factors underlying these events. Detecting when changes in social organization occur, especially with incomplete data, poses significant analytical challenges. To resolve this issue, I developed and assessed a straightforward, multi-stage and generalizable method with broad utility for ecologists interested in detecting and subsequently investigating causes of changes in social organization. My approach illustrates the frequency and ecological relevance of group fission and fusion events in a population of fish-eating 'Resident' killer whales (Orcinus orca). Group fission is a process commonly found in social mammals, yet is poorly described in many taxa, and has never been formally described in killer whales. To address this gap, I provided the first description of matrilineal fission in killer whales, from a threatened but growing Northern Resident killer whale population in which matrilineal fission has been observed for the past three decades. I also undertook the first comprehensive assessment of how killer whale intragroup cohesion is influenced by group structure, demography and resource abundance. Fission in Northern Resident killer whales occurred both along and across maternal lines, where animals dispersed in parallel with their closest maternal kin. I show that fission in this population is driven primarily by population growth and the demographic conditions of groups, particularly those dictating the nutritional requirements of the group. I posit that intragroup food competition is the most likely explanation for group fission in this population, where prey abundance also has ancillary effects. As group fission can have a direct impact on the fitness of group members and the long-term viability of a population, my findings underscore the importance of incorporating studies of sociality into the management of threatened populations of social mammals.
