Molecular weight (Mw) effects in poly(vinylidene fluoride) (PVDF) influence both processability and combustion behavior energetic Al–PVDF filaments. Results show decreased viscosity unloaded fuel-lean (i.e., 15 wt% Al) In highly loaded filaments 30 Al), reduced is minimal due to higher electrostatic interaction between Al particles low Mw chains as confirmed by Fourier-transform infrared spectr...

Simard et al. (2011) have produced a comprehensive data set and analysis concerning mountain pine beetle (MPB; Dendroctonus ponderosae)-caused mortality and associated crown fire feedbacks in lodgepole pine (Pinus contorta)-dominated forests. Misapplication of the NEXUS fire modeling system (Scott and Reinhardt 2001) results in the suspect conclusion that active crown fire (perpetuation of flam...

For the purpose of developing the capability to produce fission Mo, the Chilean Nuclear Energy Commission is participating in the IAEA Coordinated Research Project: “Developing Techniques for Small Scale Indigenous Mo-99 Production using LEU Fission or Neutron Activation”. Fission Mo will be produced irradiating, at RECH-1 reactor, a target made of a LEU metallic uranium foil held between two c...

Peter Diakow Department of Mechanical and Materials Engineering, Queen’s University, Kingston, Canada Synopsis Dimethyl-ether (C2H6O) a common hydrocarbon is increasingly being used as a transportation fuel and as an aerosol propellant, very limited explosion safety data is available for this fuel. Experiments were performed to determine the detonation characteristics of dimethyl-ether air mixt...

Active control techniques for the gust loads alleviation/flutter suppression have been investigated extensively in the last decades to control the aeroelastic response, and improve the handling qualities of the aircraft. Nonadaptive feedback control algorithms such as classical single input single output techniques (Schmidt & Chen, 1986), linear quadratic regulator (LQR) theory (Mahesh et al., ...
