A semi-microrespirometer

A Simplified Differential Microrespirometer

A Modified Capillary Microrespirometer

Modifications which enable simpler operation of the Cunningham-Barth-Kirk microrespirometer are described and an example of its use is quoted. Added advantages include easy positioning of indicator drop in the capillary and thermal equilibration at atmospheric pressure.

A New Form of Differential Microrespirometer

1. A microrespirometer suitable for measuring oxygen uptakes from 0.1 to 10lambda per hour is described. 2. The sensitivity of the instrument may be readily altered by substituting different sizes of capillary tubing. 3. By means of replaceable brass plugs the chamber volume of this instrument may be varied from 700 to less than 40lambda. 4. No thermostat is required for the operation of the in...

A Versatile Microrespirometer for Routine Use

A new design of microrespirometer suitable for routine laboratory work has been described.

A note on semi-regular locales

Semi-regular locales are extensions of the classical semiregular spaces. We investigate the conditions such that semi-regularization is a functor. We also investigate the conditions such that semi-regularization is a reflection or coreflection.
