This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Winner of the prestigious Moto Award for "Best Technical How-to Book" in 1984, the Metal Fabricator's Handbook applies master metal craftsman Ron Fournier's unique metal fabricating skills—developed during years of building Indy cars, drag racers, stockers, custom show cars, and sports GT race cars. Covers MIG, TIG, arc- and gas-welding, fuel and oil tanks, exhaust headers, and much more.

In February 1999, only a few weeks before the U.S. Air Force spearheaded NATO's Allied Force air campaign against Serbia, Col. C.R. Anderegg, USAF (Ret.), visited the commander of the U.S. Air Forces in Europe. Colonel Anderegg had known Gen. John Jumper since they had served together as jet forward air controllers in Southeast Asia nearly thirty years earlier. From the vantage point of 1999, they looked back to the day in February 1970, when they first controlled a laser-guided bomb strike. In this book Anderegg takes us from "glimmers of hope" like that one through other major improvements in the Air Force that came between the Vietnam War and the Gulf War. Always central in Anderegg's account of those changes are the people who made them. This is a very personal book by an officer who participated in the transformation he describes so vividly. Much of his story revolves around the Fighter Weapons School at Nellis Air Force Base (AFB), Nevada, where he served two tours as an instructor pilot specializing in guided munitions.
