Impact point dispersion of a direct fire rocket can be drastically reduced with a ring of appropriately sized lateral pulse jets coupled to a trajectory tracking flight control system. The system is shown to work well against uncertainty in the form of initial off-axis angular velocity perturbations as well as...
Given the high probability of national and federal research laboratories continuing to sponsor science education partnerships between their staff and classroom science teachers and the dearth of research in this area, this study set out to delineate best practices associated with such partnerships for the purpose of increasing the effectiveness...
Avian movement behavior provides insight on patterns of regional and local fidelity, habitat and resource requirements, the scale at which individuals perceive the landscape, and the relative influence of the spatial array of resources. Shorebirds (suborder: Charadrii) are a diverse and mobile group of wetland associated species. Large numbers of...
The bacterium Pseudomonas syringae affects different crops worldwide. In the
Willamette Valley of Oregon, P. syringae causes bacterial canker in sweet cherry,
severely limiting its production. High grafting of susceptible sweet cherry cultivars to
resistant rootstocks is practiced in the Willamette Valley to reduce incidence of this
disease. The research...
Exploratory synthesis plays an important role in the quest to discover new materials. There are very few structurally characterized alkali metal containing bismuth vanadates. Hybridization of the 6s and 6p orbitals of Bi[superscript 3+] and the resulting lone electron pair yields some very interesting stereochemistry and steric related properties. Some...
