Bears and bureaucrats, timber and telephone lines, poaching and predators, fires and families – all these play a part in this fascinating study of Canada’s National Park wardens. The warden service has been integral to Canada’s National Parks from their earliest days. First established in Rocky Mountains Park (now Banff National Park) in 1909, the position of Fire and Game Guardian was the precursor of today’s National Park warden, whose duties now include resource management, law enforcement, and public safety.
The need to understand the biological processes that are important for essential aquatic and terrestrial ecosystem function has prompted much research into the field of ecological enzymology. This book presents the two broad areas of application in a compilation of reviews by 21 international experts in their respective fields. The first explores enzymatic activities to assess the processes or mechanisms that operate in a given system, such as the rhizosphere, plant leaves and shoots, soil surfaces, and biofilms.
by National Research Council (U.S.). Committee on Review of the Conduct of Operations for Remediation of Recovered Chemical Warfare Materiel from Burial Sites , National Research Council (U.S.). Board on Army Science and Technology , Language: English
As the result of disposal practices from the early to mid-twentieth century, approximately 250 sites in 40 states, the District of Columbia, and 3 territories are known or suspected to have buried chemical warfare materiel (CWM). Much of this CWM is likely to occur in the form of small finds that necessitate the continuation of the Army’s capability to transport treatment systems to disposal locations for destruction. Of greatest concern for the future are sites in residential areas and large sites on legacy military installations.

This book explores the discontinuous Galerkin (DG) method, also known as the discontinuous finite element method, in depth.
Fiber-reinforced polymer (FRP) composites have become an integral part of the construction industry because of their versatility, enhanced durability and resistance to fatigue and corrosion, high strength-to-weight ratio, accelerated construction, and lower maintenance and life-cycle costs. Advanced FRP composite materials are also emerging for a wide range of civil infrastructure applications. These include everything from bridge decks, bridge strengthening and repairs, and seismic retrofit to marine waterfront structures and sustainable, energy-efficient housing.
Airfield Safety and Capacity Improvements: Case Studies on Successful Projects presents six case studies focused on the planning, engineering, and management of major construction projects at active airports. The construction or reconstruction of runways, aprons, ramps, or terminals while an airport is open for regular operations poses complex challenges, such as access to and from airport operating areas, logistics, staging, short-term lighting and signage, airline-airport communications, and staging and planning for short-term closures of taxiways and taxi lanes.

Since the first edition was published over a decade ago, advancements have been made in the design, operation, and maintenance of sewer systems, and new problems have emerged. For example, sewer processes are now integrated in computer models, and simultaneously, odor and corrosion problems caused by hydrogen sulfide and other volatile organic compounds, as well as other potential health issues, have caused environmental concerns to rise. Reflecting the most current developments, Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, offers the reader updated and valuable information on the sewer as a chemical and biological reactor.

The catastrophic earthquakes of the last decades have seriously undermined there putation of steel structures, which in the past represented the most suitable solution for seismic resistant structures. Even if in very few cases, the performance of steel joints and members was unexpectedly bad, showing that it was due to some lacks in the current design concep
Selected chapters from the German concrete yearbook are now being published in the new English “Beton-Kalender Series” for the benefit of an international audience.
Since it was founded in 1906, the Ernst & Sohn “Beton-Kalender” has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in “ferro-concrete” structures until – as the book’s first editor, Fritz von Emperger (1862-1942), expressed it – the “tempestuous development” in this form of construction came to an end.
