Download or read book Tables for Emission Spectrographic Analysis of Rare Earth Elements written by Ch. Kerekes and published by Elsevier. This book was released on 2013-10-22 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas and Tables for Emission Spectrographic Analysis of Rare Earth Elements focuses on the analysis of rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion. The book first offers information on the division of the spectra of rare earth elements and Sc and Y into three groups. The spectra of Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er have lines that, however, do not form characteristic line groups. The text underscores that in preparing the Atlas, the spectral pure-grade rare earth oxides sold by the Johnson & Matthey Co. were considered. Through the help of their spectra, the usable analysis lines and the wavelength values of the interfering spectral lines are created. The operating and photographic conditions are tabulated. The book stresses that for each rare earth, the analysis lines are provided in order of decreasing wavelength. The number located in the lower left corner for each analysis line indicates its relative intensity. The fifteen columns contain the interfering lines of other rare earths and of Sc and Y. The interfering lines are created through the use of the double projector of the Optica Milano Co. and the Gatterer Spectrum. The text is a great source of information for readers wanting to analyze rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion.

Download or read book More Universe at Your Fingertips written by Andrew Fraknoi and published by Astronomical Society of the pacific. This book was released on 2000 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because the original was so popular, the geniuses behind Project ASTRO have created an additional volume of activities. These 25 activities explore and explain mysteries of the universe: the moon's phases, the reasons for the seasons, comets and meteors, stars, and space exploration. Also designed in loose-leaf format, More Universe... is a great supplement to the original, or a perfect sampler if you want to start small.

Download or read book The Geology of the Guiana Shield written by Allan K. Gibbs and published by Oxford University Press, USA. This book was released on 1993 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Guiana Shield is an area of special importance, especially to those concerned with Precambrian geology because it provides a perspective on a part of Earth history not well represented elsewhere. For economic geologists, its mineral resource potential is just beginning to be understood. This overview of current knowledge will greatly help geologists already working in the area, draw attention to the need for mineral exploration research, and encourage the inclusion of the Shield in future Precambrian studies.

Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Book excerpt: "Substantially the book that devotees of the director have been waiting for: a full-length critical work about Ozu's life, career and working methods, buttressed with reproductions of pages from his notebooks and shooting scripts, numerous quotes from co-workers and Japanese critics, a great many stills and an unusually detailed filmography."—Sight and Sound Yasujiro Ozu, the man whom his kinsmen consider the most Japanese for all film directors, had but one major subject, the Japanese family, and but one major theme, its dissolution. The Japanese family in dissolution figures in every one of his fifty-three films. In his later pictures, the whole world exists in one family, the characters are family members rather than members of a society, and the ends of the earth seem no more distant than the outside of the house.
