Forest Soils - Properties and Processes (Paperback): Ken Armson Forest Soils - Properties and Processes (Paperback)
Ken Armson
R1,385 Discovery Miles 13 850 Ships in 10 - 15 working days

This is a comprehensive study of forest soils for foresters, wildlife and park managers, ecologists, and others interested in forest soils. It provides a valuable text for introductory and more advanced courses. The first ten chapters deal with basic soil information: texture, structure, and porosity; colour, temperature, and aeration; water; organic content; biological organisms and processes; chemistry; fertility; classification; and surveys. The last six chapters consider the components of the forest soil systems as related processes, discussing roots, fire, and water and nutrient cycles as they exist in natural forests and as they are modified by man. Professor Armson examines the process of forest soil development, and the place of soil as a part of a continuously changing landscape from both the historical and ecological viewpoints. An appendix describes the procedures for soil profile description and sampling. Full bibliographical references are supplied.

Metamorphism & Electricity - Metamorphic Contributions to Electrical Phenomena in the Earth's Crust (Paperback): Daniel S.... Metamorphism & Electricity - Metamorphic Contributions to Electrical Phenomena in the Earth's Crust (Paperback)
Daniel S. Helman
R650 R604 Discovery Miles 6 040 Save R46 (7%) Ships in 10 - 15 working days

Metamorphism generates electrical and magnetic phenomena, and is influenced by these forces. Information fundamental to their combined study is presented, including examples from microtectonics, crystal physics, geophysics, seismology, mineralogy and materials science. Applications for earthquake prediction, planetary science research, alternative energy and science education are included. Work on reported seismic electric signals is analyzed and summarized. Ten hypotheses related to earthquake mechanisms and prediction are presented, as well as eighteen recommendations for further study. Eight microtectonic deformation mechanisms are explored. Two hundred seventeen descriptions of minerals exhibiting ferroelectricity, pyroelectricity or piezoelectricity are presented, with quantitative data where known. Fifty-three of these are centrosymmetric, and explanations are given for their apparent violations of crystal theory. A comprehensive list of thirty-two mechanisms that generate telluric currents is also presented, as are some novel or inexpensive experimental techniques in crystal physics.

R531 Discovery Miles 5 310 Ships in 10 - 15 working days

Large temperate rivers around the world have been historically affected by human activities and face an uncertain future in which water quality may be further threatened by climate change, urban development, agriculture, exotic species, recreation, and transportation uses (Meybeck and Helmer 1989; Zhang et al. 1999). In addition, large rivers can transfer water quality pollutants from land to sea, such as agricultural nitrogen in the Mississippi River causing hypoxia in the Gulf of Mexico (Burkart and James 1999).

Fossil Fuels in the Arab World: Facts and Fiction - Global and Arab Insights of Oil, Natural Gas & Coal (Paperback): Basel... Fossil Fuels in the Arab World: Facts and Fiction - Global and Arab Insights of Oil, Natural Gas & Coal (Paperback)
Basel Nashat Asmar
R1,228 Discovery Miles 12 280 Ships in 10 - 15 working days

Is the Arab world an indispensable energy source without which our civilisation will come to a halt? Is this the cause of political and military meddling in the Arab world's affairs, and the reason given by democratic western leaders to defend supporting autocratic and authoritarian Arab governments to stay in power? Is the world really this vulnerable? Assessment of mankind's dependence on fossil fuels, particularly the position of the Arab world, is performed by analysing the three types (oil, natural gas, and coal), which are in essence convertible. Fossil fuels are tackled from two angles: clarifying the terminology used by the media, politicians, scientists, and so-called experts, when discussing fossil fuels; evaluating the hard facts and separate them from fiction by analysing the numbers and scrutinise them impartially to come with a definitive quantitative answer. Finally, a further investigation examines fossil fuels in relation to alternative energy, and from political perspective.

The United States relies on imports for dozens of commodities in everyday use. Often enough, that reliance is 100%. This book provides awareness of the hidden geology and mineralogy behind common things, and develops an appreciation for the global resource distribution that underpins our society. While concerns about oil import reliance are in the news every day, our needs for other minerals are comparable, and are typically unknown even to technologically aware Americans.

Ancient civilizations used the finest stones to set into their idols, decorate their temples, and to adorn themselves. These people used all different sizes and colors of gemstones and these gemstones were set in sliver, gold and other minerals that they made metals. Gemstones made legends of both wealth and history in many parts of the world. Using richly colored gems in trading, inlaying them in jewelry, jeweled crowns, and garments were just a few ways that created that gleam and glitter when rays of light hit a stone. The play of colors giving the gemstones stunning effects. Leaders, kings, priests, medicine men, and others have put many different values on rocks and gemstones. A few of these values are monetary, symbols of great power, healing energies, spiritually and great wealth. In the world today rocks and gemstones are used as they were yet in ancient times and for many of these same reasons. Gemstones both semi-precious and precious are used some way or another by almost every age group, sex and personality. Each stone has a different energy and purpose. In some instances a thrill of excitement is felt by a person just looking at, using or owning a gemstone. Colorful and cut gemstones attract attention because of their beauty and ability to move energy levels and states of mind according to their vibration levels. This statement is also true for all of the uncut stones in the mineral kingdom.
