Biological handbook for engineers
Microbiological background information is compiled in handbook for engineers and scientists working on bio-related projects. It is intended as aid in - /1/ evaluating effects of engineering procedures on microbial life, /2/ determining effects of decontamination and sterilization on performance of overall systems, and /3/ understanding language of microbiologists.

Electrodeposited inorganic separators for alkaline batteries
Coating electrodes of silver-cadmium cells with thermostable electrodeposits of calcium hydroxide or magnesium hydroxide reduces silver migration and increases cell life. Absence of organic matter enables assembled cells to be sterilized without oxidation of the material of the separators.
