Book Description
The reserves, or extractable fraction, of the fuel-mineral endowment are sufficient to supply the bulk of the world's energy requirements for the immediately forseeable future-well into the next century according to even the most pessimistic predictions. But increasingly sophisticated exploration concepts and technology must be employed to maintain and, if possible, add to the reserve base. Most of the world's fuel-mineral resources are in sedimentary rocks. Any procedure or concept that helps describe, under stand, and predict the external geometry and internal attributes of major sedimentary units can therefore contribute to discovery and recovery of coal, uranium, and petroleum. While conceding the desirability of renewable and nonpolluting energy supply from gravitational, wind, or solar sources, the widespread deployment of these systems lies far in the future-thus the continued commercial emphasis on conventional nonrenewable fuel mineral resources, even though their relative significance will fluctuate with time. For example, a decade ago the progilostications for uranium were uniformly optimistic. But in the early 1980s the uranium picture is quite sombre, although unlikely to remain permanently depressed. Whether uranium soars to the heights of early expectations remains to be seen. Problems of waste disposal and public acceptance persist. Fusion reactors may ultimately eliminate the need for uranium in power generation, but for the next few decades there will be continued demand for uranium to fuel existing power plants and those that come on stream. This book is, to some extent, a hybrid.

Book Description
The infraorder Pentatomomorpha is the subject of the second volume in the Zoological Catalogue of Australia series dealing with the true bugs (the suborder Heteroptera). It includes the bark bugs, stilt bugs, seed bugs, cotton stainers, burrowing bugs, shield bugs and stink bugs. Many of these species are of significant economic importance both as pests and as natural enemies of other insect pests. In this catalogue, the authors propose a new classification for the Australian Heteroptera based on the most recent developments in heteropterology worldwide. The proposed classification departs significantly from all previous treatment of the Australian fauna. There is a comprehensive treatment of the classification and nomenclature of the Australian species and a thorough review of the literature concerned with the higher classification of the Pentatomomorpha. The volume gives detailed information on the distribution and ecology of each species and features the first in depth listing of their host associations, including a significant accounting of the plant associations. All species and generic synonymies are given, including extra-limital synonyms, along with detailed type specimen data. Features * Provides a new classification for the Australian Heteroptera, reflecting the most recent developments in Heteropterology worldwide * Covers 34 families, 439 genera and 1179 species * Completes the work for the Australian Heteroptera, complementing volume 27.3A * Includes comprehensive synonymical and bibliographic listings and detailed distribution information * Gives the first listing of the host plants of the Pentatomomorpha in Australia * Sample

Book Description
This book is a classic narrative of modern exploration; a story of adventure, enterprise and patient scientific exploration, illustrated by photographs taken on the expedition. The Simpson is a sand-ridge desert extending 200 miles (322 km) west to east, the ridges running parallel from north to south at roughly quarter-mile (0.4 km) intervals, some reaching as high as 100 feet (30 m). Madigan planned a ground crossing in the winter of 1939. A party of nine, including a biologist, a botanist, a photographer and a radio operator, with nineteen camels, made the exhausting crossing from Andado station in the Northern Territory to Birdsville in twenty-five days. It verified Madigan's previous conclusions that the area was a wasteland. This last classic Australian exploration adventure pioneered the use of mobile radio communication; national broadcasts were made through the Australian Broadcasting Commission from desert camps. The scientific results were published and also a popular accound, Crossing the Dead Heart (Melbourne, 1946). He saw the 'Dead Heart' as a land of everlasting sand-ridges and salt-encrusted clay-pans; while his conclusions seemed correct then, within twenty years the area was criss-crossed by petroleum explorers. - Australian Dictionary of Biography
