Distribution of \u3ci\u3eStrongylium Crenatum\u3c/i\u3e (Coleoptera: Tenebrionidae) in the United States and First Record From Iowa

Strongylium crenatum Mäklin (Coleoptera: Tenebrionidae) is reported from Iowa for the first time. After discovering that Iowa represented a large range extension for this species, label data were collected to update its range. Numerous insect collections and references were checked and specimens representing 17 states were located

New State Records for \u3ci\u3ePerillus Strigipes\u3c/i\u3e (Heteroptera: Pentatomidae: Asopinae)

The stink bug Perillus strigipes is reported from Alabama, Iowa, Kansas, Louisiana, Maine, and Mississippi for the first time. This insect species has a wide distribution but generally is seldom collected

Utilization of Moire patterns as an orbital docking aid to space shuttle/Space Station Freedom

Moire patterns are investigated as possible docking aids for use between the National Space Transportations System (Space Shuttle Orbiter) and the Space Station Freedom. A sight reticle placed in optical conjunction with a docking target can generate moire fringes from which position and alignment can be inferred. Design specifications and a mathematical development to meet those specifications are discussed. A motion based simulator and experimental hardware have been constructed

Statistics of Extreme Gravitational Lensing Events. I.The Zero Shear Case

For a given source and lens pair, there is a thin on-axis tube-like volume behind the lens in which the radiation flux from the source is greatly increased due to gravitational lensing. Any objects (such as dust grains) which pass through such a thin tube will experience strong bursts of radiation, i.e., Extreme Gravitational Lensing Events (EGLE). We study the physics and statistics of EGLE for the case in which finite source size is more important than shear. One of the several possible significant astrophysical effects is investigated with an illustrative calculation.Comment: revised and final published version including a new section on the destruction of dust grains in globular clusters as an exampl
