A chromatin thermostat

A microcomputer- controlled thermostat

Introduction Careful temperature control is essential for a wide variety of chemical measurements. High-precision potentiometry, for instance, requires thermostatting, since the slope of the straight line E vs log a is highly temperature dependent (E is the measured emf, log a is the logarithm of the activity of species i). The equation describing the relationship between the measured quantity ...

Thermostat for Lower Temperatures

Details are given concerning the construction and operation of relatively simple thermostats which permit maintaining precise temperatures down to 0 degrees C. (with water), or temperatures above that of the ordinary room, and in which the temperature may be quickly altered at short intervals to new levels.

15Geoengineering’s Thermostat Dilemma

Geoengineering is gaining attention as a possible tool for ameliorating climate change. These largely untested techniques are sometimes analogised to a thermostat that will enable humans to finetune the Earth’s climate. Although overly simplistic, this metaphor highlights a fundamental dilemma that the capacity to geoengineer would raise: whose hand should control the thermostat? Unpacking this...

The Construction of a Thermostat-room

The receipt by the author of a number of inquiries regarding the building of a thermostat-room has led him to bring together in a brief paper certain facts which might prove of value to those interested in the subject. Every well-appointed bacteriological laboratory, in which teaching of large-sized classes is carried on, should be equipped with an incubator-room, for experience has shown t h a...
