Laccase Production By Chaetomium Elatum, A Soft-Rot Fungus, Wilson H. Howe, Joyce M. Hardin
Laccase Production By Chaetomium Elatum, A Soft-Rot Fungus, Wilson H. Howe, Joyce M. Hardin
Journal of the Arkansas Academy of Science
Though enzymes responsible for rotting wood have been studied for some time, the enzymes and enzymatic systems responsible for breaking down lignin have only begun to be discovered. The lignin-degrading enzymes produced by soft-rot fungi, in particular, have not been sufficiently studied. The present study presents evidence that the enzyme called laccase, known to be associated with lignin biodegradation, is produced by the species Chaetomium elatum, a soft-rot fungus. Cerrena unicolor, a positive control, and Chaetomium elatum were grown in culture. These species were tested for the presence of laccase using syringaldazine as a chromogenic substrate. As expected, Cerrena unicolor …

Complexity Of Fetal Movement Detection Using A Single Doppler Ultrasound Transducer, William A. Russell Jr., Curtis L. Lowery, Patrick J. Baggot, James D. Wilson, Robert Walls, Roger M. Hawk, Pam Murphy
Journal of the Arkansas Academy of Science
The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the …
Use Of Visual And Tactile Behaviors By Rats (Rattus Norvegicus) In An Object Discrimination Swimming Task, Todd Wiebers
Use Of Visual And Tactile Behaviors By Rats (Rattus Norvegicus) In An Object Discrimination Swimming Task, Todd Wiebers
Journal of the Arkansas Academy of Science
When challenged with a cognitive task, rats demonstrate a behavioral flexibility in use and preference of sensory modalities. The present study describes visual and tactile behaviors used by rats in a two choice object discrimination swimming task. The task was designed to preclude use of other sensory modalities and could not be solved via spatial strategies. Fourteen rats learned to criterion a series of 10 discrimination problems. Rats exhibited three stereotypic visual and two stereotypic tactile behaviors over the course of the study. Data analyses indicated that rats demonstrated these behaviors more frequently as they became more familiar with the …
