The combustion apparatus described provides a rapid and inexpensive alternative for
measurement of radioisotopes in plant parts. The apparatus utilized a nickel-chromium …

IT would be virtually impossible to describe in detail all applications of radioactive and
flourescent tracers in a single paper. Therefore, this paper is limited to research being done …

Compared with the conventional end window Geiger tube, the jacketed counter for the
radioassay of liquids had higher precision and counting efficiency, eliminated the need for …

A major obstacle limiting field studies in plant population biology is that there is no way of
uniquely labeling or identifying the seeds produced by a mother plant so that her seedlings …

Studies initiated in 1960 at the Texas A. & M. College on the use of activation analysis
techniques to evaluate spray-distribution patterns are briefly described. The process …

Ring‐and carboxyl‐labelled [14C] 2, 4‐D were incubated under laboratory conditions, at the
2 g/g level, in a heavy clay, sandy loam, and clay loam at 85% of field capacity and 20 1C …

A simple inexpensive cabinet, naturally illuminated, is described. The cabinet atmosphere is
controlled in a novel manner, by heating or cooling, to maintain the interior at atmospheric …

Determination of 14C in solid residues and intact tissues has traditionally involved
combustion of samples to 14C02 (Fuchs and de Vries, 1972). However, recent meth allow …
