Preliminary Study To Determine The Effect Of Microwaves On Green Wood, Rudolph J. Eichenberger
Preliminary Study To Determine The Effect Of Microwaves On Green Wood, Rudolph J. Eichenberger
Journal of the Arkansas Academy of Science
A preliminary study was done to determine the moisture content of green wood by treating the wood with microwaves in an oven for various times between 1 and 4 minutes. The temperature of the wood was measured immediately following the radiation with a probe interfaced to a microcomputer and with a mercury-in-glass thermometer. Temperature probes were inserted into the wood samples. Actual moisture content of the wood was determined by weighing the samples before and after drying. Half of the samples exhibited a directly proportional relationship between moisture content and temperature after microwaving. The linear relationship was not generalizable to …

Vegetation Of Saratoga Landing Blackland Prairie, Thomas L. Foti
Journal of the Arkansas Academy of Science
Saratoga Landing Blackland Prairie is a 75-ha site owned by the U.S. Army Corps of Engineers and managed cooperatively with the Arkansas Natural Heritage Commission to protect its blackland prairie community and rare plant species. The site is a complex of prairies and forests, as interpreted from aerial photos and maps. It was substantially prairie at the time of settlement, and forest cover did not increase greatly until after 1951, apparently due to effective suppression of wildfires after that time. Plot sampling characterizes an individual prairie on the site as being dominated by a herbaceous canopy, but with a substantial …
