Design Concepts For Vegetated Waterways - Historic Landmark of Agricultural Engineering Rainfall runoff causes severe gully erosion on unprotected lands and has ruined thousands of U S acres in the past. Concepts were developed at this site for vegetation-lined waterways that now safely convey runoff water from millions of acres.Engineers of the US Soil Conservation Service (SCS) initiated studies on hydraulics of vegetated waterways at an outdoor laboratory near Spartanburg, South Carolina, in 1935. Under the directions of W. O.

Since 1948, over 11,000 dams and associated conservation practices in more than 2,000 watershed projects encompassing 160 million acres in 47 states have been constructed as a part of the USDA Small Watershed Program. These projects have improved the quality of life and the environment in rural communities by protecting people's lives and property, conserving soil and water resources, reducing flooding, providing economic development, recreation, and water supplies, enhancing water quality, and improving wetlands and wildlife habitat.

A Crucial Step In The Evolution Of Modern Animal Agriculture Was The Development Of Mechanical Ventilation Methods For Animal Housing. Air Inlets Are Pivotal To Good Ventilation. In 1948 William F. Millier, Working At Cornell University Under The Direction Of Professor Clesson Turner, Tested And Published The Concept Of The Slotted Inlet. Professor Turner And Others At Cornell University Subsequently Continued To Develop Slotted Inlet Systems And Systematize Design Methods.

Established in 1946 to provide a comprehensive test and evaluation site for tactical missiles, Point Mugu has been instrumental in the development, test, evaluation and in-service support of systems including Regulus, Sparrow, Phoenix, Bullpup, Harpoon, SLAM, Tomahawk, Standard, and Rolling Airframe Missile. The first missile launch from an operational submarine was also accomplished at Pt. Mugu.

On the greeting-card racks this past Christmas could be seen a minor technological miracle—a Christmas card that upon opening showed a small yellow light that glowed while the card played a tinny but recognizable version of “Jingle Bells.” The yellow light was the latest addition to a novelty that made its first appearance a couple of years ago—the electronic greeting card.
When Halley’s comet returns to our quarter of the universe this year, the great 200-inch Hale Telescope, perched high on Palomar Mountain in California, will follow it across the sky. In fact, the 200-inch, the world’s largest telescope for a full three decades after its dedication in 1948, was the first telescope to detect the comet during its current return, back in 1982. We can always expect the phenomenal from the 200-inch.
A major advance in the history of computing occurred at the University of Pennsylvania in 1946 when engineers put the Electronic Numerical Integrator and Computer (ENIAC) into operation. Designed and constructed at the Moore School of Electrical Engineering under a U. S. Army contract during World War II, the ENIAC established the practicality of large scale, electronic digital computers and strongly influenced the development of the modern, stored-program, general-purpose computer.
