This book was released on 2013-05-10 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.

Download or read book Minerals of Mexico written by William D. Panczner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: After many years of geographical and bibliographical journeys, William Panczner has completed a project that many of us would have loved to initiate, but did not undertake because of its magnitude and intrinsic complexity. Not since L. Salazar Salinas, who is credited with authoring Bole tin numeros 40 and 41 (lnstituto Geologico de Mexico, 1922, 1923), has an author been able to provide readers with a comprehensive volume containing information that is both authentic and reliable on Mexican mineralogy, mineral species, and localities. This volume is the most complete synthesis about Mexican minerals and their occurrences to date. It is richly illustrated with photographs and drawings, is well documented, and is organized into four sections, making it easy to use and enjoyable to read. The introduction contains an interesting summary of the mining history and the development of mineralogy. It also describes, in a condensed but accurate and stimulating manner, the geography and the mineralogy of the country, dividing it into eleven mineral provinces. The author discusses eight of the more important mining districts in Mexico, which produce fine mineral speci mens. There is also a chronology of historical, geological, and mineralogical events in Mexico. This is followed by a bibliography with over 500 references on the subject.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This scheme meets the need for a standard yet adaptable system of geographical units for use in recording plant distributions and arranging specimens. Because a purely political arrangement cannot meet all the needs of botanists, the scheme's arrangement compromises between a politically and a phytogeographically oriented system. It identifies geographic units worldwide in a four-level hierarchy, incorporating continents, regions, provinces and countries. Each geographical unit at each level has its own numeric or alphanumeric code. The scheme is presented in five tables, the recognized geographical units are shown in 17 maps, and a gazetteer relates over 2,100 names to the overall system.
