Download or read book Many Electron Densities and Reduced Density Matrices written by Jerzy Cioslowski and published by Springer Science & Business Media. This book was released on 2000-09-30 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science advances by leaps and bounds rather than linearly in time. I t is not uncommon for a new concept or approach to generate a lot of initial interest, only to enter a quiet period of years or decades and then suddenly reemerge as the focus of new exciting investigations. This is certainly the case of the reduced density matrices (a k a N-matrices or RDMs), whose promise of a great simplification of quantum-chemical approaches faded away when the prospects of formulating the auxil iary yet essential N-representability conditions turned quite bleak. How ever, even during the period that followed this initial disappointment, the 2-matrices and their one-particle counterparts have been ubiquitous in the formalisms of modern electronic structure theory, entering the correlated-level expressions for the first-order response properties, giv ing rise to natural spinorbitals employed in the configuration interaction method and in rigorous analysis of electronic wavefunctions, and al lowing direct calculations of ionization potentials through the extended Koopmans'theorem. The recent research of Nakatsuji, Valdemoro, and Mazziotti her alds a renaissance of the concept of RDlvls that promotes them from the role of interpretive tools and auxiliary quantities to that of central variables of new electron correlation formalisms. Thanks to the economy of information offered by RDMs, these formalisms surpass the conven tional approaches in conciseness and elegance of formulation. As such, they hold the promise of opening an entirely new chapter of quantum chemistry.

Download or read book In Her Lifetime written by Committee to Study Female Morbidity and Mortality in Sub-Saharan Africa and published by National Academies Press. This book was released on 1996-03-20 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relative lack of information on determinants of disease, disability, and death at major stages of a woman's lifespan and the excess morbidity and premature mortality that this engenders has important adverse social and economic ramifications, not only for Sub-Saharan Africa, but also for other regions of the world as well. Women bear much of the weight of world production in both traditional and modern industries. In Sub-Saharan Africa, for example, women contribute approximately 60 to 80 percent of agricultural labor. Worldwide, it is estimated that women are the sole supporters in 18 to 30 percent of all families, and that their financial contribution in the remainder of families is substantial and often crucial. This book provides a solid documentary base that can be used to develop an agenda to guide research and health policy formulation on female health--both for Sub-Saharan Africa and for other regions of the developing world. This book could also help facilitate ongoing, collaboration between African researchers on women's health and their U.S. colleagues. Chapters cover such topics as demographics, nutritional status, obstetric morbidity and mortality, mental health problems, and sexually transmitted diseases, including HIV.

Download or read book Agroclimatology written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Download or read book African Philosophy written by Guttorm Fløistad and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is a continuation of two earlier series of chroni cles, Philosophy of the Mid-Century (Firenze 1958/59) and Con temporary Philosophy (Firenze 1968), edited by Raymond Klibansky. Like the other series, these chronicles provide a survey of significant trends in contemporary philosophical discussion from 1970 to 1985. The need for such surveys has, I believe, increased rather than decreased over the last years. The philosophical scene appears, for various reasons, more complex than ever before. The continuing process of specialization in most branches, the emergence of new schools of thought, the convergence of interest (thought not neces sarily of opinion) of different traditions upon certain problems, the increasing attention being paid to the history of philosophy in discussions of contemporary problems, and the growing signifi cance for philosophical discourse of the social, political and cul tural situation in various regions of the world are the most impor tant contributory factors. Surveys of the present kind are a valu able source of knowledge of this complexity and may as such be an assistance in renewing the understanding of one's own philo sophical problems. The surveys, it is to be hoped, may also help to strengthen a world-wide Socratic element of modern philosophy, the dialogue or Kommunikationsgemeinschaft. So far, five volumes have been prepared for the new series.
