The USDA Small Watershed Program
Society: ASABE Main Category: Agricultural & Biological Sub Category: Drainage & Watershed Era: 1940-1949 DateCreated: 1948 USDA Natural Resources Conservation Service State Office Stillwater State: OK Zip: 74074 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/the-usda-small-watershed-program-57.aspx Creator:

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.

Once-Over Mechanical Harvesting of Cucumbers
Society: ASABE Main Category: Agricultural & Biological Sub Category: Mechanization Era: 1960-1969 DateCreated: 1963 Farrall Agricultural Engineering Hall East Lansing State: MI Zip: 48824 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/the-once-over-mechanical-harvesting-of-cucumbers-55.aspx Creator: Bill Stout

The concept of once-over mechanical, as opposed to multiple-pick hand or experimental multiple-pick machine harvesting, represented a major break-through in the practice of producing vine fruit such as pickling cucumbers.  In the 1950s the cost of hand harvesting was as high as 50% of the production cost.  Once-over mechanical harvesting, coupled with increasing plant population, reduced this cost to 25% thereby making production economically viable.

Anhydrous Ammonia Application Technology
Society: ASABE Main Category: Agricultural & Biological Sub Category: Chemical Era: 1930-1939 DateCreated: 1932 Delta Research and Extension Center Stoneville State: MS Zip: 38776 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/anhydrous-ammonia-application-technology-56.aspx Creator: Edwards, Felix, Smith, J. O., Andrews, W. B.

In 1932, J. O. Smith, Agricultural Engineer at Delta Branch Experiment Station in Stoneville, MS, attached a small anhydrous ammonia cylinder to a plow in such a manner that the NH3 was released in the soil.  The plow, a Georgia Stock, was pulled by a gray mule named Ike.  This was the first known use of anhydrous ammonia as a soil-applied crop fertilizer.  The crude apparatus and the anhydrous ammonia it applied provided a much needed source of nitrogen for the otherwise rich alluvial soils of the Mississippi Delta.

However because it is such a hazardous material and is difficult to apply, many farmers choose to hire third party businesses to store and apply the fertilizer. Era_date_from:
airport of Getafe
Society: AIAA Main Category: Aerospace & Aviation Sub Category: Aviation Era: 1910-1919 DateCreated: 1911 Getafe Air Base Getafe State: Zip: Country: Spain Website: https://www.aiaa.org/uploadedFiles/About_AIAA/News_Room/GetafeHistoricSitePR.pdf Creator:

Getafe Airfield was the site of the world’s first successful rotorcraft flight, on January 17, 1923. Lieutenant Alejandro Gómez Spencer piloted a C.4 Autogiro designed and built by Juan de la Cierva, who tested a series of autogiros between 1920 and 1924 at the Getafe site. Cierva’s autogiros introduced important technologies and flight techniques that led to the development of helicopters and other rotary wing aircraft.

UTICA MEMORIAL AUDITORIUM
Society: ASCE Main Category: Civil Sub Category: Era: 1950s DateCreated: 1959 400 Oriskany St W Utica State: NY Zip: Country: USA Website: http://www.asce.org/project/utica-memorail-auditorium/ Creator: Zetlin, Lev

The roof system of this building, designed by Lev Zetlin and opened in 1960, was the first of its kind in the world. Before the mid-1950's, the use of long-span cable structures was generally limited to suspension bridges. The only other significant cable roof structure preceding the Utica Memorial Auditorium was the North Carolina State Fair Livestock Judging Pavilion, completed in 1953.

In August 1974, the first real-time speech communication over a packet-switched network was demonstrated via ARPANET between MIT Lincoln Laboratory and USC Information Sciences Institute. By 1982, these technologies enabled Internet packet speech and conferencing linking terrestrial, packet radio, and satellite networks.

Satellite

NHK began the world's first direct broadcast satellite service in May, 1984. This was the culmination of eighteen years of research that included the development of an inexpensive low-noise receiver and investigations of rain attenuation in the 12 GHz band. RRL, NASDA, TSCJ, Toshiba Corporation, General Electric Company, and NASA participated with NHK to make satellite broadcasting to the home a practical reality.

Operating since 1972, Eel River, New Brunswick is home to the world's first commercial solid state High Voltage Direct Current converter station. This 320 MW interconnection facility, built by Canadian General Electric and NB Power, incorporates high current silicon solid state thyristors to convert alternating current from Hydro Quebec to direct current and back to alternating, allowing asynchronous, stable power transfers to serve New Brunswick's Power's customers.

Discovery of Superconductivity
Society: IEEE Main Category: Electric Sub Category: Research Era: 1910-1919 DateCreated: 1911 Kamerlingh Onnes Building, Leiden University Leiden State: Zip: Country: Netherlands Website: http://www.ieeeghn.org/wiki/index.php/Milestones:Discovery_of_Superconductivity,_1911 Creator: Onne, Heike Kamerlingh

On 8 April 1911, Professor Heike Kamerlingh Onnes and his collaborators, Cornelis Dorsman, Gerrit Jan Flim, and Gilles Holst, discovered superconductivity.   They observed that the resistance of mercury approached  "practically zero" as its temperature was lowered to 3 kelvins.  Today, superconductivity makes many electrical technologies possible,  including Magnetic Resonance Imaging (MRI) and high-energy particle accelerators.

In the early 1970s, American chemist Paul C. Lauterbur demonstrated that nuclear magnetic resonance (NMR) could be used to generate images of macroscopic objects. In the years following, magnetic resonance imaging (MRI) has been refined as a technique for the detailed resolution of internal structures. Lauterbur’s invention thus created a powerful diagnostic tool for the non-invasive examination of body tissues such as the brain, heart, and muscles. It allows for the early detection of cancer and other diseases.
