Characterization of JP-8/SiO2 and RP-1/SiO2 Gels
No full textFor next generation air-breathing and rocket propulsion systems gelled propellants can be a promising replacement for conventional solid and liquid propellants. Especially for rocket engine operation, the application of a gelled fuel and gelled oxidizer can combine the advantages of conventional solid and liquid propellants without taking into account the specific disadvantages of both individual systems. The present publication describes the rheological behavior of gelled JP-8 turbine fuel and gelled rocket propellant RP-1 when fumed silica is used as a gelling agent. Alongside the determination of an optimal gel mixing process, gel stability and rheological parameters showed a significant influence of the added silica amount

No full textSpecies identification of Anguilla eels by polymerase chain reaction /restriction fragment length polymorphism analysis of the gonadotropin II-beta subunit gene
No full textGonadotropin II beta-subunit gene (GTH II-β DNA) fragments of nine eel species of the genus Anguilla were amplified with specific oligonucleotides by polymerase chain reaction (PCR), and a single product was obtained from each species. In subsequent restriction fragment length polymorphism (RFLP) analysis of the PCR-amplified GTH II-β DNA, the restriction endonuclease Hpa II, Sph I and Nsi I gave restriction patterns that differed among 3 species, e.g., Anguilla japonica, A. bicolor bicolor and A. anguilla, with other six species of anguillid eels, e.g., A. rostrata, A. australis australis, A. reinhardti, A. celebesensis, A. marmorata, and A. bicolor pacifica. Our results suggest that the PCR/RFLP analysis provides a rapid and convenient method to discriminate eel species

Shock tube study of JP-10 ignition delay time
No full textJP-10 (exo-tetrahydrodicyclopentadiene, C10H16) ignition delay times were measured in a preheated shock tube. The vapor pressures of the JP-10 were measured directly by using a high-precision vacuum gauge, to remedy the difficulty in determining the gaseous concentrations of heavy hydrocarbon fuel arising from the adsorption on the wall in shock tube experiments. The whole variation of pressure and emission of the OH or CH radicals were observed in the ignition process by a pressure transducer and a photomultiplier with a monochromator. The emission of the OH or CH radicals was used to identify the time to ignition. Experiments were performed over the pressure range of 151-556 kPa, temperature range of 1000-2100 K, fuel concentrations of 0.1%-0.55% mole fraction, and stoichiometric ratios of 0.25, 0.5, 1.0 and 2.0. The experimental results show that for the lower and higher temperature ranges, there are different dependency relationships of the ignition time on the temperature and the concentrations of JP-10 and oxygen
