Subtle cellular phenotypes in the CNS may evade detection by routine histopathology. Here, we demonstrate the value of primary culture for revealing genetically determined neuronal phenotypes at high resolution. Gamma neurons of Drosophila melanogaster mushroom bodies (MBs) are remodeled during metamorphosis under the control of the steroid hormone 20-hydroxyecdysone (20E). In vitro , wild-type γ neurons retain characteristic morphogenetic features, notably a single axon-like dominant primary process ...

Kraft pulp fiber reinforced cement-based materials are being increasingly used where performance after exposure to environmental conditions must be ensured. However, significant losses in mechanical performance due to wet/dry cycling have been observed in these composites, when portland cement is the only cementitious material used in the matrix. In this research program, the effects of partial portland cement replacement with various supplementary cementitious materials were investigated. Binary, ...

In this research program, aligned pulp fiber sheets were used as reinforcement in cement-based matrices. Flexural testing results validate this reinforcement strategy by demonstrating that: (1) fiber sheet alignment does significantly affect mechanical behavior, indicating that fiber alignment is achieved by the production process, and (2) aligned fiber sheet composite exhibited significantly greater toughness than equivalent volumes of distributed fibers. Additional results indicate that the addition ...

If pulp fiber–cement composites are to be used for exterior applications, the effect of cyclical wet/dry exposure must be known. In this research program the effects of three fiber treatments—beating, bleaching, and drying—were investigated to identify those that may minimize effects of environmental aging and degradation during wet/dry cycling. After 25 wet/dry cycles, all composites showed significant losses in first crack strength, peak strength, and post-cracking toughness. The majority of losses ...
