Motion of Magnetically Driven Arcs on Oxidized Electrodes
Experiments were carried out on a number of oxidized metals such as copper, brass, aluminum, and steel. Two kinds of rectangular electrodes were investigated, narrow and wide electrodes. On the narrow oxidized electrodes the arc moved slowly and sometimes discontinuously during its first run. During subsequent runs the arcs moved continuously along the same path of the first run with speeds which were ten times faster than the first run. On the wide oxidized electrodes however no slowdown of the arc was observed during its first run. It ran right away continuously with speeds similar to the subsequent runs.

air at VA facilities, one of the many pieces of unfinished business beyond those major issues that we discussed in our Commentary. We agree that all facilities where current and past military personnel serve and receive treatment should be 100% smoke-free and note the recent Institute of Medicine report Combating Tobacco in Military and Veteran Populations. The report, which was commissioned by the Department of Defense (DOD) in 2007, calls for the DOD to set a timeline to eliminate smoking on military installations. The report also recommends that the DOD stop selling tobacco products in military commissaries and exchanges, prohibit tobacco use anywhere on military installations, and treat tobacco use in the same way as other health-related behaviors, such as alcohol abuse and poor physical fitness. We join Matthews and the Institute of Medicine in urging the VA and the DOD to take more immediate steps to protect the health of the men and women who serve in the armed services, as well as the civilians (such as Dr Matthews) working to serve them.
