Six illustrative cases of homicidal drowning are reported in which the diatom test for drowning was a useful adjunct to the medicolegal investigation of death. In all six cases, diatom frustules were recovered from the femoral bone marrow. In five cases, diatoms extracted from the bone marrow were compared with diatoms obtained from samples of putative

The Rise of the Rhizosolenid Diatoms
Science, 2004The 18S ribosomal DNA molecular phylogeny and lipid composition of over 120 marine diatoms showed that the capability to biosynthesize highly branched isoprenoid (HBI) alkenes is restricted to two specific phylogenetic clusters, which independently evolved in centric and pennate diatoms. The molecular record of C 25

Semiclassical theory for diatom-diatom collisions
Chemical Physics Letters, 1983Abstract A semiclassical approach to diatom-diatom collisions is presented. The method involves a classical treatment of the translational and rotational motion of both molecules. The vibrational degrees of freedom are quantized using a Morse oscillator approximation. The method is used to evaluate the accuracy of previous calculations based upon the

Notes for a Short Course: Studies in Geology, 1987
Diatoms are unicellular golden brown algae, that are characterized by an external box-like skeleton (or frustule) of opaline silica. Diatom frustules are commonly very intricate and varied, and the patterns and types of ornamentation of the frustule form the basis of nearly all diatom taxonomy. The size of diatom frustules ranges from less than one μm (
