Because of this advantage, LIBS has been used as a tool for inspecting materials in underwater archaeology, where knowledge of the chemical composition may provide valuable clues on the origin of materials in shipwrecks and submerged buildings.
The origin of materials was confirmed taxonomically by Profs.
The origin of materials was confirmed and standardized taxonomically by the Traditional Chinese Medicine Herbal Pharmacy, Guangzhou University of TCM.
The origin of materials was confirmed taxonomically by Prof. Je-Hyun Lee of Dongguk University (Gyeongju, Republic of Korea) and Prof. Young-Bae Seo of Daejeon University (Daejeon, Republic of Korea).
The minor peak of radioactive material that elutes at 20 mM NaCl was not always present and the origin of this material remains unclear (Durrant-Arico, C. and Moore S.E.H., results not shown).
The arcs formed on or near ancient continental crust (about 2.0 to 2.4 billion years old), but the origin of the material in these arcs is uncertain.
Mr. Green, in a reversal, pledged to "investigate fully and thoroughly the origin" of the material, and he said that anyone involved "will have no role in my campaign or my administration".
"APP's chain of custody system traces the origin of raw material, evaluates its legal and environmental status, to minimise the risk of contamination and to ensure that endangered species are protected – in accordance with the laws of Indonesia".
Dr. Michael W.W. Adams, a biochemist who studies early life at the University of Georgia, said Dr. Wachtershauser had developed a very reasonable and testable hypothesis for the origin of organic material relevant to life.
