Diaphragm failure rate

Other methods, such as the diaphragm, condoms and lUDs, can carry even higher failure rates, depending on whether usual or perfect compliance calculation of 18-6%, 12-2% and 3-... 

These include the cost of labour, the cost of replacing components and the rent and rates on the area of land. A comparison of the latter is very unfavourable to diaphragm cells where almost twice as much land is necessary because of the low current density and the need for evaporation plant. Membrane and mercury cells have similar land requirements because the former are packed together closely in a filter press and to some extent the electrodes scale vertically. All the processes are largely automated and hence the difference in labour costs is likely to arise because of a variable incidence of component and pipework failure. Certainly the need to replace diaphragms on a routine cycle increases the labour costs for the diaphragm cell process. 

Initial interest on Conus venoms focused on the most dangerous species Conus geographus), as well as other species that have inflicted serious envenomations in humans. C. geographus, the species responsible for most human deaths, has an estimated fatality rate of 70% compared to the overall rate of <40% for all species (Yoshiba, 1984). Death is attributed mainly to paralysis of the diaphragm muscle with consequent respiratory failure (Cruz and White, 1995). Compared to neurotoxic snakebites, the onset of symptoms in Conus...
