Chemical control of soda-lime efficiency in circle filters.
NON NOSCERE" continues to be one of the most important aphorisms—if not the most important of all—in contemporary medicine and anaesthetists should never ignore it. The use of elaborate anaesthetic technique entails correlated dangers, which can only be counteracted by minute and profound knowledge of the situation created. Under this heading comes closed circuit respiration, which to-day is so...
متن کاملDry soda lime markedly degrades sevoflurane during simulated inhalation induction.
We have investigated gas composition during simulated inhalation induction with sevoflurane to elucidate possible mechanisms of incidental prolonged induction times and airway irritation. Using a circle system, 8% sevoflurane in oxygen 6 litre min-1 was washed into an absorbing canister filled with fresh soda lime containing 2.9% KOH (Draegersorb, 'D') or no KOH (< 0.01%, Sofnolime, 'S'). The a...
متن کاملResidual stresses in a soda-lime-silica glass-ceramic
The present study was undertaken to test the validity of existing models for: (i) the residual internal stresses which arise due to thermal and elastic mismatch in duplex systems; and (ii) the critical particle diameter for spontaneous cracking. The specimens studied were bulk nucleated, partially crystallized 17.20Na,0-32.09Ca0-4.12Si0,-2.59P,O, (mol%) glasses. The residual stress was determin...
متن کاملNumerical Simulation of Soda-Lime Silicate Glass Tempering
The paper deals with the computation of residual and transient stresses in a tempered glass plate. The modelling takes into account the viscoelastic behavior and the structural relaxation of glass. The evolution of stresses with time during the rapid cooling is computed. Simulation results are compared with experimental ones from the literature available. Levels of transient tensile stress in t...
متن کاملColor center formation in soda lime glass and NaCl single crystals with femtosecond laser pulses
The high instantaneous powers associated with femtosecond lasers can color many nominally transparent materials. Although the excitations responsible for this defect formation occur on subpicosecond time scales, subsequent interactions between the resulting electronic and lattice defects complicate the evolution of color center formation and decay. These interactions must be understood in order...
