This paper reports previously obtained results concerning topographic change in a water area. Latitude-longitude components of positional data from GPS receiver were transformed to planar orthogonal coordinates, and vertical combined with depth an echo sounder. A piecewise linear function defined on triangular mesh represented surface that fitted measurement results. study applied those techniq...

[reaction: see text] Computational methods were used to determine the structure, bonding, and aggregation states of oxiranyllithium in the gas phase and in THF solution, at 200 and 298 K. THF solvation was modeled by microsolvation with explicit THF ligands, forming a supermolecule that includes the oxiranyllithium aggregate and its first solvation shell. Because oxiranyllithium has a chiral ce...
