BY assuming a sufficient number of sufficiently insignificant individuals to constitute a group, it is possible to imagine a state of things in which as far as it can be observed from a certain distance, all evidence of individual action is entirely lost. In this way has been framed the ...

摘要: The equilibrium thermodynamic properties of gaseous mixtures at high temperatures are treated by an extension of the cluster theory of Ursell, omitting the assumption of additivity of pair energies. An effective partition function is introduced, which is a convenient function...
A Redlich-Kwong type of equation of state for gaseous CO2 with a and b being functions of molecular volume is proposed. This equation fits observed P-V-T data for gaseous CO2 from -50o to 1000oC and from 1 bar to 10 kbar, and predicts observed heat capacity values quite well. Geoche...
Clay and clay-based minerals show non-covalent adsorptive behavior through three ways onto various molecules from liquid to gaseous state. Physical adsorption where non-ionic adsorption takes place onto the clay surface (larger surface area compromised in small volumes). ...
The influence of postannealing in different gaseous environments on the optical properties of indiu-tin-oxide (ITO) thin films deposited on glass substrates using e-beam evaporation has been systematically investigated. It is found that the annealing conditions affect the optical and electrical properti...
