Influence of stream flow on epilithic diatom communities and its consequence for water quality monitoring [PDF]
, 1993 Epilithic diatom communities and relevant physico-chemical variables were studied between 3 May and 16 July 1993 in Harwood Beck, an oligotrophic stream in Upper Teesdale, and the River Browney, a lowland eutrophic river.

A rigorous test of the statistical model for atom–diatom insertion reactions
The Journal of Chemical Physics, 2003 The statistical model of atom–diatom insertion reactions is combined with coupled-channel capture theory and used to calculate differential cross sections for the reactions of C(1D), N(2D), O(1D) and S(1D) with H2. In the case of C(1D) and S(1D), the resulting statistical differential cross sections are found to be in excellent agreement with the ...

Advanced Science, EarlyView.This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Distance decay of similarity in neotropical diatom communities. [PDF]
PLoS ONE, 2012 BackgroundThe regression of similarity against distance unites several ecological phenomena, and thus provides a highly useful approach for illustrating the spatial turnover across sites.

Herbicide effects on freshwater benthic diatoms: Induction of nucleus alterations and silica cell wall abnormalities [PDF]
, 2008 Benthic diatoms are well known bio-indicators of river pollution by nutrients (nitrogen and phosphorus). Biological indexes, based on diatom sensitivity for non-toxic pollution, have been developed to assess the water quality.Nevertheless, they are not ...
