Automation of Vapour Pressure Osmometry measurements
A program has been developed for the control of Vapour Pressure Osmometry (VPO) measurements. The output signal of a Vapour Pressure Osmometer is read by an A/D converter card installed in one of the expansion slots of a PC microcomputer. The stability of the measurements is checked by analysing the first derivative of the smoothed signals, which is calculated in real time. Sets of repeated mea...

متن کاملPressure effects on water vapour lines: beyond the Voigt profile.
A short overview of recent results on the effects of pressure (collisions) regarding the shape of isolated infrared lines of water vapour is presented. The first part of this study considers the basic collisional quantities, which are the pressure-broadening and -shifting coefficients, central parameters of the Lorentzian (and Voigt) profile and thus of any sophisticated line-shape model. Throu...
متن کاملVapour Pressure Changes in the Frog ' S Egg at Fertilization
INTRODUCTION The suggestion has been made that the response of an egg to the action of a spermatozoon or parthenogenetic agent may be similar to that of a nerve to stimulation (Lillie, 1909). If this were so, it might be expected that activation, whether by a parthenogenetic agent or by a spermatozoon, would cause an increase in the permeability of the egg surface; although this increase in per...
متن کاملLow Pressure Chemical Vapour Deposition at Quasi- High Flow
A new chemical vapour deposition (CVD) technique is presented. It is especially advantageous for the deposition of compound materials. The technique improves the uniformity and reproducibility of the deposition. The economical use of gaseous reactants is improved by a factor varying between 5 and 20. This is important in the case of expensive metal-organic CVD methods. The method consists in th...
