It was Hamilton who had begun the 1944 tracer experiments on rats.
2.
Tracer experiments have shown that phenylalanine is a major precursor, but other carbon sources also contribute.
3.
In 1945, human tracer experiments began with the intent to determine how to properly analyze excretion samples to estimate body burden.
4.
The mechanism of formation has been studied enzymatically, as well as with tracer experiments, but the exact route of synthesis still remains unclear.
5.
The series of studies culminated in the Winter Haze Intensive Tracer Experiment ( WHITEX ) and the Navajo Generating Station Visibility Study ( NGSVS ).
6.
Tracer experiments were begun in 1944 with rats and other animals with the knowledge of all of the Manhattan project managers and health directors of the various sites.
7.
He said that " seed tracer experiments " show that when 10 or 15 subsistence farmers are given an improved seed variety one year, 150 to 200 farmers in the same community will be planting that seed the following year.
8.
The weak energy of carbon-14 made measurement tedious, so tedious that no tracer experiments with C-14 were done until 1942 when Ruben gave all his barium carbonate-14 C to Chemistry Department faculty member Andrew Benson who began his long series of 14 CO 2 fixation experiments to determine the path of carbon in photosynthesis.
