Response of selected plant and insect species to simulated solid rocket exhaust mixtures and to exhaust components from solid rocket fuels

The effects of solid rocket fuel (SRF) exhaust on selected plant and and insect species in the Merritt Island, Florida area was investigated in order to determine if the exhaust clouds generated by shuttle launches would adversely affect the native, plants of the Merritt Island Wildlife Refuge, the citrus production, or the beekeeping industry of the island. Conditions were simulated in greenhouse exposure chambers and field chambers constructed to model the ideal continuous stirred tank reactor. A plant exposure system was developed for dispensing and monitoring the two major chemicals in SRF exhaust, HCl and Al203, and for dispensing and monitoring SRF exhaust (controlled fuel burns). Plants native to Merritt Island, Florida were grown and used as test species. Dose-response relationships were determined for short term exposure of selected plant species to HCl, Al203, and mixtures of the two to SRF exhaust

Unusual Thermal Stability of a Site-Ordered MC60 Rocksalt Structure (M=K, Rb, or Cs)

X-ray diffraction and differential scanning calorimetry of MxC60, with x∼1 and M=K, Rb, or Cs, reveal an unusual T-dependent phase sequence. A low-symmetry ground state is found, while the high-T limit is an ordered rocksalt structure in which only the octahedral sites are occupied. The unusual high-T stability of this ordered phase is attributed to the entropy of molecular orientational disorder and/or thermal disorder of the alkali-metal ions within the octahedral sites. Unique to KxC60 with x≥1.4, we find at intermediate temperatures an fcc site-disordered lattice gas phase with random occupancy of tetrahedral and octahedral sites, which is thus isostructural with superconducting K3C60

Improving Bus Service in New York

New York City’s transportation system is in a state of disarray. City street are clogged with taxi’s and for-hire vehicles, subway platforms are packed with straphangers waiting for delayed trains and buses barely travel faster than pedestrians. The bureaucracy of City and State government in the region causes piecemeal improvements which do not keep up with the state of disrepair. Bus service is particularly poor, moving at rates incomparable with the rest of the country. New York has recently made successful efforts at improving bus speeds, but only so much can be done amidst a city of gridlock. Bus systems around the world faced similar challenges and successfully implemented improvements. A toolbox of near-immediate and long-term options are at New York’s disposal dealing directly with bus service as well indirect causes of poor bus service. The failing subway system has prompted public discussion concerning bus service. A significant cause of poor service in New York is congestion. A number of measures are capable of improving congestion and consequently, bus service. Due to the city’s limited capacity at implementing short-term solutions, the most highly problematic routes should receive priority. Routes with slow speeds, high rates of bunching and high ridership are concentrated in Manhattan and Downtown Brooklyn which also cater to the most subway riders. These areas would also benefit the greatest from congestion mitigation measures
