Abstract: The present invention is a method for determining the position of a source emitting at least one of a gaseous compound and particles in a geographical area, comprising measuring the gaseous compound concentration, the wind direction and speed for different predefined consecutive geographical positions to deviate by at most 45° from an instantaneous or average wind direction. At least one pair of a consecutive minimum and maximum of the curve is subsequently determined, and the position of the emission source is determined from the positions of the mobile measurement system corresponding to the maxima of the pairs, the time gaps between the maximum and minimum of the pairs, and average wind speeds and directions between the minimum and maximum of the pairs.

Abstract: The invention relates to a method of determining at least one quantity relative to the adsorption of at least one adsorbable gas in a sample of a porous medium, wherein the following steps are carried out: (i) determining a Darcy velocity by injecting an inert gas for a given gradient and by measuring the inert gas flow rate downstream from the sample, (ii) determining an adsorbable gas breakthrough velocity by injecting the adsorbable gas for the same gradient and by measuring the adsorbable gas quantity downstream from the sample as a function of time, and (iii) determining a kinematic porosity using the ratio of the Darcy velocity to the adsorbable gas breakthrough velocity.
