An attempt was made to apply to the study of immune sera the fact, pointed out in our previous papers, that at a given dilution the serum shows a maximum drop of surface tension in function of time (time-drop). The results of the experiments here reported would seem to indicate that: 1. The time-drop of a serum solution is greater after the animal has been immunized than before immunization (fr...

In this paper we propose the following expression for surface tension of organic compounds:

As stated in previous papers, 1-4 the four essential conditions under which the presence of antibodies in immune serum can be detected and followed by means of what might be termed the tensiometric method are: first, the dilution of the serum to 1:10,000; second, the use of strictly clean vessels; third, the care in handling the solutions, which must absolutely not be disturbed between the two ...

Given that most of the gaseous constituents of industrial chimneys are usually carbon dioxide which is one of the most important greenhouse gases. It seems that the hydration process is one of the newest methods for the separation of this gas from gaseous mixtures. In the gas hydrate formation industry, in addition to disadvantages, there are some advantages such as gas separation, transmission...
