Numbers, Sizes, and Types of Diatoms Around Estuaries for a Diatom Test

American Journal of Forensic Medicine & Pathology, 2011
We collected 68 fresh, brackish, and seawater samples from various sites around the estuaries of 2 rivers at high and low tides. Seawater flowed approximately 2.4 (salinity, 2.2% at the site) and 1.2 km (1.8%) upstream of the estuaries, but the surface comprised essentially fresh water up to the mouth.

Testing the specificity of the diatom test: search for false-positives

Medicine, Science and the Law, 2011
The diatom test is widely used by forensic pathologists as proof of drowning, notwithstanding some criticisms mainly concerning the occurrence of false-positive results (presence of diatoms in the tissues of subjects who died from causes other than drowning).

Testing the response of benthic diatom assemblages to common riverine contaminants

Science of The Total Environment, 2021
Benthic diatoms constitute keystone assemblages in riverine ecosystems, and their structure is used to support regulatory water quality assessment. However, no standard ecotoxicological tests exist using integrated responses of the benthic diatom assemblages.

Diatoms in space: testing prospects for reliable diatom nanotechnology in microgravity

SPIE Proceedings, 2007
The worldwide effort to grow nanotechnology, rather than use lithography, focuses on diatoms, single cell eukaryotic algae with ornate silica shells, which can be replaced by oxides and ceramics, or reduced to elemental silicon, to create complex nanostructures with compositions of industrial and electronics importance. Diatoms produce an enormous

A Test of the Influence of Cyclotron Resonance Exposures on Diatom Motility

Health Physics, 1994
An attempt was made to test the hypothesis (McLeod et al. 1987; Smith et al. 1987) that a certain combination of direct current and alternating current magnetic field exposures at room temperature results in an increase in motility of a marine diatom (Amphora coffeaeformis) to a maximum value.

Diatom test with Soluene-350 to diagnose drowning in sea water

Forensic Science International, 1999
The authors tested the Soluene-350 method to detect diatoms in three cases of sea water drowning. The negative results obtained in all three cases prompted us to re-test the method on samples of fresh water and sea water microalgae. The experiment showed that the siliceous frustule of sea water diatoms is solubilized by Soluene-350 while that of fresh ...
