Download or read book Alberta Oil Sands written by Kevin E Percy and published by Newnes. This book was released on 2012-11-29 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: At 170 billion barrels, Canada's Oil Sands are the third largest reserves of developable oil in the world. The Oil Sands now produce about 1.6 million barrels per day, with production expected to double by 2025 to about 3.7 million barrels per day. The Athabasca Oil Sands Region (AOSR) in northeastern Alberta is the largest of the three oil sands deposits. Bitumen in the oil sands is recovered through one of two primary methods - mining and drilling. About 20 per cent of the reserves are close to the surface and can be mined using large shovels and trucks. Of concern are the effects of the industrial development on the environment. Both human-made and natural sources emit oxides of sulphur and nitrogen, trace elements and persistent organic compounds. Of additional concern are ground level ozone and greenhouse gases. Because of the requirement on operators to comply with the air quality regulatory policies, and to address public concerns, the not-for-profit, multi-stakeholder Wood Buffalo Environmental Association (WBEA) has since 1997 been closely monitoring air quality in AOSR. In 2008, WBEA assembled a distinguished group of international scientists who have been conducting measurements and practical research on various aspects of air emissions and their potential effects on terrestrial receptors. This book is a synthesis of the concepts and results of those on-going studies. It contains 19 chapters ranging from a global perspective of energy production, measurement methodologies and behavior of various air pollutants during fossil fuel production in a boreal forest ecosystem, towards designing and deploying a multi-disciplinary, proactive, and long-term environmental monitoring system that will also meet regulatory expectations. Covers measurement of emissions from very large industrial sources in a region with huge international media profile Validation of measurement technologies can be applied globally The new approaches to ecological monitoring described can be applied in other forested regions

Download or read book The Pentatomoidea Hemiptera of Northeastern North America with Emphasis on the Fauna of Illinois written by John Edwin McPherson and published by SIU Press. This book was released on 1982 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive work introduces the reader to the well-represented pentatomoid fauna of northeastern North America. About 120 species and subspecies in five families are presently known to occur in this geographical area. The text begins with a closely defined classification of the Pentatomoidea within the order Hemiptera. A discussion of the his­tory of the investigations of North American Pentatomoidea follows, with a list of selected faunistic surveys by state or province and a general discussion of the pentatomoid life cy­cle including overwintering stages, spring emergence and mating, oviposition and sub­sequent development to adults. Here the au­thor also considers the scent glands and the possible functions of their secretions. This volume provides updated keys to the northeastern North American penta­tomoids, illustrations, references to revision­ary studies of families and genera, statements and maps of distribution, pertinent biologi­cal information regarding field life cycles, laboratory rearing, immature stages, host plants and prey, and parasites and predators. Unique within its field, this book was written for individuals interested in insects as well as those specializing in Hemiptera.
