Radial shock waves impact the metabolism of GAG in chondrocytes in equine articular cartilage. Further studies will be required to fully investigate the impact of this effect on the health of joints, and to elucidate the clinical impact.

RESWT as applied in the present study has no effect on acute palmar heel region scintigraphic or radiographic parameters. Any acute clinical benefit may be due to analgesic effects rather than stimulation of local tissue metabolism.

This article discusses a problem with high iron content in the well water supply of three Alaskan towns. Such water supply situations are widespread in remote Alaskan communities. High hardness in all three supplies presented a treatment challenge that was magnified by lack of continuous electric power and very low winter temperatures. Batch lime treatment, settling, and decantation reduced the iron content and the hardness at two of the three towns. Aeration, batch lime treatment, settling, and decantation reduced the iron content and the hardness at the third. The resulting waters were free of chlorine demand and tastes and odors. Jar tests were used to determine the optimum lime doses.

The U.S. Alaskan Air Command, the Environmental Engineering Section of the Arctic Health Research Laboratory, U.S. Public Health Service, conducted a study of the heat balance of the 2 million gallon water storage tank at Kotzebue U.S. Air Force Station. The objective of the study was to develop design and operating criteria for water tanks in the arctic.
