Opuntia Humifusa

A new population of Opuntia humifusa (Raf.) Raf. was found in Pike County, Kentucky. Consequent examination of other misidentified populations in Kentucky (Harlan and Pike counties) and West Virginia (Jackson County) provides the first known occurrences of Opuntia humifusa (sensu stricto) in Kentucky and a confirmed range extension into the Unglaciated Appalachian Plateaus Province.

Abstract Stygobromus doughertyensis n. sp. is described from groundwater habitats in Jackson County, Florida and Dougherty County, Georgia, USA using both morphological and molecular methods. This species occurs syntopically with the morphologically similar S. floridanus, which is newly recorded in Jackson County. The occurrence of S. floridanus in Jackson County marks a range extension for this species, which was described from two caves in Washington County, Florida. The description of S. doughertyensis n. sp. brings the number of described species in the genus Stygobromus to 142 and marks the second species of Stygobromus to be described from the Floridan aquifer.

This article provides a new record for Typhlops amoipira from municipality of Bonito de Minas, state of Minas Gerais. The record extends its distribution about 500 km southern from the type locality at Ibiraba, state of Bahia. The collection site is also located on the left bank of the São Francisco River, and is dominated by cerrado sensu stricto with sandy soils, Veredas and riparian forests, in a transitional region between Cerrado and Caatinga biomes. This record confirms that the occurrence of T. amoipira goes beyond the borders of the Caatinga biome.

Launch Angle

A Hybrid Projectile (HP) currently under design at West Virginia University was simulated to estimate the effects of barrel launch angle and flight position of wing deployment. The projectile is similar to a standard 60mm mortar, except that is has been equipped to achieve extended range. A Simulink model was developed based upon external ballistics. The flight performance of the WVU-HP-60 was compared to a standard M720 60mm mortar. The developed HP was considered to be a tube-launched UAV, that transforms, not directly after launch but sometime after for optimal gliding, and must be modeled with different flight profiles because after transformation the aerodynamics drastically change. Two models of the UAV were created to allow for design of controllers. They were the launch model and the projectile flight model. It was found that the projectile may exit the barrel with a two degree variation of launch angle. The simulations show that range extension is still viable, with this barrel exit variation, to within 10% of the maximum achievable range. A confidence area was also developed to determine how far the launch angle and wing deployment position could stray and still maintain a significant amount of range extension.
