The Collier Trophy is an annual aviation award administered by the U. S. National Aeronautic Association ( NAA ), presented to those who have made " the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year.

The NAA has been steeply involved with the growth of aviation in the United States almost since its beginning, to the point of being the sole issuer of pilot licenses in American until the Civil Aeronautics Act of 1926.

The NAA has three distinct responsibilities: The recording and certification of Aviation and Aerospace Records, the administration of Aviation Trophies and Awards, and working with Air Sports Organizations in America on the advancement of their individual sports.

The NAA has certified aviation and aerospace records in the United States since 1905 and its records database counts over 7, 300 record flights to include those of balloons, airships, airplanes, ( landplanes, seaplanes, amphibians, very light jets ,) gliders, helicopters, autogiros, model aircraft, parachutes, human powered aircraft, spacecraft, tilt-wing / tilt-engine aircraft, hang gliders, paragliders, microlights, space models, and UAVs.

Within the United States and its Territories, the NAA has the sole responsibility of administering awards established by the FAI.

As of January 1, 2012, NAA has 2, 800 individual members.

However, on May 27 hostilities broke out between the NAA and the MVD troops based in Yerevan, resulting in the deaths of five Armenians killed in a shootout at the railway station.

Administered jointly by NAA and the Air Care Alliance there are five categories for this award: Distinguished Volunteer Pilot, Distinguished Volunteer, Outstanding Achievement in Advancement of Public Benefit Flying, Public Benefit Flying Teamwork Award, and Champion of Public Benefit Flying.

The NAA was founded in 1905 as the Aero Club of America ( ACA ), by members of the Automobile Club of America.

NAA did retain ownership of Eastern Air Lines until 1938.

The name became official in 1944, and the award presented once a year by the NAA president, with the trophy on permanent display at the U. S. National Air and Space Museum.

The NAA and the Smithsonian Institution's National Air and Space Museum worked to assemble a complete list to be published in conjunction with the NAA's hundredth anniversary in 2005, however this project was not completed and it appears that the source documents for a period of awards were destroyed.

The United State Air Force determines the recipient and NAA awards it.

The NAA encourages and supports the development and growth of the sport of aviation in the United States and does so primarily through its relationship with eight Air Sport Organizations ( ASOs ) based in the country.

It was renamed in his honor in 1922 when the Aero Club dissolved, and the award was taken over by the NAA.

In chemistry, neutron activation analysis ( NAA ) is a nuclear process used for determining the concentrations of elements in a vast amount of materials.

NAA allows discrete sampling of elements as it disregards the chemical form of a sample, and focuses solely on its nucleus.

NAA can also be used to determine the activity of a radioactive sample.

NAA was discovered in 1936 by Hevesy and Levi, who found that samples containing certain rare earth elements became highly radioactive after exposure to a source of neutrons.

NAA is significantly different from other spectroscopic analytical techniques in that it is based not on electronic transitions but on nuclear transitions.

To carry out an NAA analysis the specimen is placed into a suitable irradiation facility and bombarded with neutrons.

For the NAA procedure to be successful the specimen or sample must be selected carefully.

NAA can vary according to a number of experimental parameters.

A relatively simple Farnsworth – Hirsch fusor can be used to generate neutrons for NAA experiments.

There are a number of detector types and configurations used in NAA.

The most common types of gamma detectors encountered in NAA are the gas ionisation type, scintillation type and the semiconductor type.

NAA can detect up to 74 elements depending upon the experimental procedure, with minimum detection limits ranging from 0. 1 to 1x10 < sup > 6 </ sup > ng g < sup >− 1 </ sup > depending on element under investigation.
