Elemental Composition Analysis of Sheep Tears Using Particle-Induced X-Ray Emission. [PDF]
Vet OphthalmolABSTRACT Objective To identify the elemental composition of ovine tears using particle‐induced X‐ray emission (PIXE). Animals Studied Ten physically healthy female sheep. Procedures Tear samples were collected using Schirmer tear test strips. Tear samples were collected once daily over five consecutive days to assess reproducibility. Elemental analysis

Pix Proteins and the Evolution of Centrioles [PDF]
PLoS ONE, 2008 We have made a wide phylogenetic survey of Pix proteins, which are constituents of vertebrate centrioles in most eukaryotes. We have also surveyed the presence and structure of flagella or cilia and centrioles in these organisms, as far as is possible from published information.

Detection angle resolved PIXE and the equivalent depth concept for thin film characterization
, 2022 S.372-375The characterization of thin films using PIXE, although basically a simple matter, in practice suffers from significant problems. Here two case studies are presented in which the use of grazing detection geometry is shown to be a good solution ...

Characterization of lacustrine iron sulfide particles with proton-induced X-ray emission. [PDF]
, 1992 Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford ...

X-Ray Spectrometry, 2005 Abstract Two selected examples of PIXE microanalysis in ecophysiology are presented. Studies of heavy metal distributions in mycorrhizal and non‐mycorrhizal roots of Plantago lanceolata showed different filtration mechanisms of Zn/Pb and Fe/Mn, both enabling plants to cope ...
