2. Experiments on terminal disinfection by formaldehyde vapor in the case of smallpox.
The usually recommended terminal disinfection by formaldehyde vapor is unable to completely inactivate vaccinia viruses embedded in scabs. In view of our results, we recommend doubling the concentration of formaldehyde (10 g of formaldehyde per m3 of space) and prolonging the time of exposure to 24 h for terminal disinfection in the case of smallpox. Subsequ

4. Terminal disinfection of infant feeds
A time and temperature relationship required to destroy certain pathogenic organisms in milk feeds has been ascertained. A method of achieving this destruction by using steam at atmospheric pressure is described, and a routine method for use in milk kitchens is suggested.

5. Terminal Disinfection in Hospitals with Quaternary Ammonium Compounds by Use of a Spray-Fog Technique
Spray-fogging of hospital rooms with a quarternary ammonium disinfectant was found to be an effective means of reducing the number of detectable airborne and surface bacteria. The level of bacterial contamination in hospital rooms was determined before and after fogging by means of the gravitational fallout method, the petri dish swab technique, and volumetr

6. Ammonia- and Nitrite-Oxidizing Bacterial Communities in a Pilot-Scale Chloraminated Drinking Water Distribution System
Nitrification in drinking water distribution systems is a common operational problem for many utilities that use chloramines for secondary disinfection. The diversity of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in the distribution systems of a pilot-scale chloraminated drinking water treatment system was characterized using termi
