✦ Synopsis

The World Health Organization is currently assessing various solarpowered refrigerators; amongst these is a photovoltaic-powered type. The vaccine "cold chain" from manufacturer to user must maintain temperatures of 4 Β°C -8 Β°C. A 90 1 size refrigerator (12 V d.c.) powered by 2 m 2 of silicon cells is currently undergoing field trials around the world. Optimal designs for the 10 l, 40 1 and 80 1 sizes are presented here; good insulation and icemaking capability are emphasized. Absorption, compression and thermoelectric types are compared; a 40 1 refrigerator will require 1.3 m 2 of photocells for absorption or compression types. Costs, as estimated, appear to be reasonable.

## Abstract An increase in volatile fatty acids (VFA) concentration (or the proportional decrease in carbonate alkalinity concentration) is the first practical measurable indication that an anaerobic treatment system is in a state of stress. If the system is not rectified at this early stage, failu
