2010/2/8
A design of and initial results from a Knudsen Effusion Mass Spectrometer (KEMS) are presented. The design was adapted from high temperature alloy studies with a view to using it to measure vapour pre...
A step-by-step procedure for pH model construction in aquatic systems
step-by-step procedure pH model construction aquatic systems
font style='font-size:12px;'>
2010/1/15
We present, by means of a simple example, a comprehensive step-by-step procedure to consistently derive a pH model of aquatic systems. As pH modelling is inherently complex, we make every step of the ...
