Charge raising operator

If we take the isospin raising current J+ = J -I- iJ, the associated charge operator is now the isospin raising operator T+ (see Section 1.3) whose effect on a state of definite isospin is given in (1.3.15). FVom the above one deduces... 

Flammable liquids are considered particularly static-prone if their elec trical conductivity is within the range of 0.1 to 10 pS/m. If no particulates or immiscible liquid are present, these prodlic ts are considered safe when their conductivity has been raised to 50 pS/m or higher. Blending operations or other two-phase mixing may cause such a high rate of charging that a conductivity of at least 1000 pS/m is needed for safe charge dissipation (British Standard 5958, part 1, Control of Undesirable Static Electricity, para. 8, 1991). 

Pile Driving Device. Said to have originated in America, this device uses a cartridge of expl placed between the head of a wooden pile and a driving ram. The expin of the charge drives the pile into the ground and simultaneously raises the ram which, upon falling, drives the pile further. This idea was utilized in drop hammers which were explosively, not steam, operated... 

The experimental programme was mainly concerned with estimating kinetic parameters from isothermal steady state operation of the reactor. For these runs, the reactor was charged with the reactants, in such proportions that the mixture resulting from their complete conversion approximated the expected steady state, as far as total polymer concentrations was concerned. In order to conserve reactants, the reactor was raised to the operating temperature in batch mode. When this temperature had been attained, continuous flow operation commenced. This was...
