Determination of Potassium and Iron Concentrations in Whole Blood by Proton-Excited X-Ray Analysis
… levels can be released in the form of an X-ray. Owing to the uniqueness of the energy levels of each element, X-rays provide a means of "fingerprinting" the elements in a sample. In this respect each element has its own set of characteristic X-rays which can be used for elemental …

Studies on the Subterranean Activity of Laricobius spp. (Coleoptera: Derodontidae) using 3D X-ray Analysis and Three Imidacloprid Soil Application Techniques
… during their subterranean life phase using 3D X-ray microscopy. When held in containers with two differing soil compaction intensities, 0.2 kg/cm2 and 0.5 kg/cm2, Laricobius spp. were found to burrow an average (± SE) of 2.7 ± 1.5 cm and 1.4 ± 1.3 cm deep, respectively. The second study assessed …
