Proton Induced X-Ray Emission Analysis Of Biological Specimens - Past And Future, B. Forslind, K. G. Malmqvist, J. Pallon
Proton Induced X-Ray Emission Analysis Of Biological Specimens - Past And Future, B. Forslind, K. G. Malmqvist, J. Pallon
Scanning Microscopy
Proton induced X-ray emission (PIXE) analysis is a comparatively new member of the family of spectrographic methods. In the last decade PIXE techniques have been applied to biological problems with great success. This review gives a condensed presentation of recent developments in biological (medical, zoological, and botanical) applications of PIXE analysis with special focus on factors which commonly influence the results, such as calibration, contamination, and preparation. The great advantage of PIXE analysis in studying physiologically important trace elements such as Zn, Mg, Fe, and Cu is underlined. Elemental mapping not only allows quantitative elemental analysis, but can also demonstrate …

Tb146: The Eccentric Bogs Of Maine: A Rare Wetland Type In The United States, Ronald B. Davis, Dennis S. Anderson
Technical Bulletins
The specific objectives of this project were to (1) map the distribution in Maine of eccentric bogs; (2) map the surface physical features and vegetation of a large sample of Maine's eccentric bogs; (3) determine for these bogs the vascular plant, bryophyte, and lichen flora; types and structure of vegetation; peat interstitial water chemistry; relationships between vegetation-flora and water chemistry; subsurface features relating to origins and development; and (4) evaluate the bogs for their unique and exemplary characteristics an d recommend certain of them to the Maine Critica l Areas Program for designation as Critical Areas.
