Interactions Between Formosan Subterranean Termites, Brown Rot Fungus (Gloeophyllum Trabeum) And Some Of The Fungi Present On The Termite Integument And Gut, Poornima Jayasimha
LSU Master's Theses
Although the brown rot fungus, Gloeophyllum trabeum (Pers.:Fr.) Murrill, has been shown to be attractive and beneficial to subterranean termites, including Coptotermes formosanus Shiraki, to date no research has been conducted to determine if the association is mutualistic. We first set out to determine if the fungus could be spread by termites. This would represent an obvious benefit to the fungus. We found that C. formosanus does not spread G. trabeum. Unexpectedly, Formosan subterranean termites were found to suppress the growth of G. trabeum. To further investigate this finding, Formosan subterranean termite workers were released into Petri dishes with wood …
Effect Of Light Intensity And Weld Thickness On The Performance Of Uv-Cured Frp Composite Joints, Jerry Alan Peck
Effect Of Light Intensity And Weld Thickness On The Performance Of Uv-Cured Frp Composite Joints, Jerry Alan Peck
LSU Master's Theses
Thirty-six FRP composite welds were wetted with UV curing vinyl ester resin and used to join fiberglass tubes. The effects of UV light intensity and weld thickness on performance (as measured by bursting pressure and stiffness) were evaluated to determine optimal conditions for joint construction. The joined composite pipes were cured vertically with UV lamps at three different light intensities, 80 mW/cm2, 35 mW/cm2 and 15 mW/cm2 to isolate the effect of UV light intensity. Eight-layer, five-layer and three-layer joints were prepared and cured at constant light intensity to evaluate the effect of reducing the thickness of the composite joint. …
