Corn-fed lawn care
A natural pre-emergence weed control made from corn gluten was developed by horticulturist Nick Christians. The corn gluten controls crabgrass and other weeds by stopping root formation and provides an environmentally friendly alternative to chemical herbicides.Christian's development is being marketed under the name A-MAIZING LAWN, by Gardens! Alive Corp., Lawrenceburg, Ind.
Airplane inspection device
The Dripless Bubbler was developed by David Hsu, senior scientist at the Center for Nondestructive Evaluation, and Thadd Patton, assistant scientist at the center. The bubbler does high-resolution, ultrasonic inspection of aircraft skins that contain protruding rivets. Rivets had rendered conventional ultrasonic scanners practically useless for detecting corrosion, bonding failure and internal defects in aircraft skins.
Swine salmonella vaccine
A vaccine produced by Ted Kramer, a veterinary microbiologist, and Michael Roof, a former graduate student of Kramer's, helps prevent swine salmonellosis, a sometimes fatal disease in young pigs.Sold as SC54 by NOBL Laboratories Inc., Sioux Center, the vaccine is unique among livestock vaccines because it uses live salmonella bacteria that have been stripped of their disease-causing capabilities. In addition, it can be administered either orally or nasally. Both options are less expensive and more convenient than injections.
Salmonella infection is estimated to cost U.S. pork producers about $100 million annually in death loss, reduced weight gains and medical costs.
