The Nearctic species of Oetophorus (Hymenoptera: Ichneumonidae, Ctenopelmatinae)

The Nearctic members of the genus Oetophorus Foerster are revised. There are four species, 0. pleuralis (Cresson), and 0. obscurus, O. clavatus, and O. maculatus, new species. The name Oetophorus stretchii (Cresson) is placed in synonymy with the name Oetophol'us pleuralis (Cresson). Relationships of the genus with others in the tribe Perilissini and relationships of the species included in the genus are briefly discussed

Analysis and design of transonic airfoils using streamwise coordinates

A new approach is developed for analysis and design of transonic airfoils. A set of full potential equivalent equations in von Mises coordinates is formulated from the Euler equations under the irrotationality and isentropic assumptions. This set is composed of a main equation for the main variable, y, and a secondary equations for the secondary variable, R. The main equation is solved by type dependent differencing combined with a shock point operator. The secondary equation is solved by marching from a non-characteristic boundary. Sample computations on NACA 0012 and biconvex airfoils show that, for the analysis problem, the present approach achieves good agreement with experimental C sub p distributions. For the design problem, the approach leads to a simple numerical algorithm in which the airfoil contour is calculated as part of the flow field solution

Special Project+ Privacy

Privacy has long been a matter of particular concern in the minds of Americans. Indeed, privacy concerns were at the crux of the American Revolution. The earliest days of colonial life saw creation of laws protecting the individual against eavesdropping, and the sanctity of one\u27s home. The Bill of Rights also reflects privacy interests. As America grew, technological advances in the dissemination of information caused public demands for protection of privacy rights; I Each year, the Vanderbilt Law Review publishes one issue with notes devoted solely to a topic of current interest. These notes collectively constitute the Special Project
