For example, Arhonditsis (2006) explored ecological structures of two lakes using SEM and showed that SEM provided a convenient means for assessing the relative role of several ecological processes known to determine the levels of water quality variables of management interest [2].
Liu (2010) used SEM to explore the influence of water chemistry on chlorophyll a in Lake Qilu.

One either had to compromise on system size, as in Dempster-Shafer theory (DFT) [2, 3] methods limited to about 100 atoms, or on accuracy and the level of chemistry that can be modelled, as done when using empirical potentials.
Note that LC structures exhibiting lattices of screw dislocations are mathematically related to the Abrikosov phase in superconductors of type II.

Y2O3 - Al2O3 binary glass microspheres: Synthesis and Characterisation Anna Prnová, Radovan Karell and Dušan Galusek Vitrum Laugaricio - Joint Glass Center of the Institute of Inorganic Chemistry, Slovak Academy of Sciences, Alexander Dubček University of Trenčín, and RONA, j.s.c., Študenstká 2, 911 50 Trenčín, Slovakia prnova@tnuni.sk, karell@tnuni.sk, galusek@tnuni.sk Keywords: glass microspheres, flame synthesis, aluminium oxide, rare earth oxides Abstract: The work reports on the preparation and properties of binary alumina-rare-earth oxide glass microspheres with high contents of aluminium oxide.
However, the fact that the density of microspheres with YAG composition is markedly lower than that of crystalline YAG (4.57 g.cm-3), implies the existence of disordered, amorphous structure.

In the case of thermoplastic matrices, on the other hand, the compound must first be melted and brought to below the melt or glass transition temperature of the respective plastic for demoulding. [14] In hot pressing or injection moulding, there are the technically demanding options of directly stamping in the required structures or producing unstructured plate blanks instead.
