Effect of Interplanetary Shock Impact Angle on the Occurrence Rate and Properties of Pc5 Waves Observed by High-Latitude Ground Magnetometers
The effects of interplanetary shock impact angles have the potential to have far reaching consequences. By their nature, interplanetary shocks are a direct consequence of a variety of solar events including both Coronal Mass Ejections (CMEs) and Co-rotating Interaction Regions (CIRs). They have the …

Observation and Measurement of the Growth of the Primary Instabilities of the Richtmyer-Meshkov Instability and Observation of Secondary Instabilities
… of the Richtmyer-Meshkov (RM) instability in a shock-accelerated, initially cylindrical gas column; that is, the counter-rotating vortex pair and the central spike; and the observation of secondary instabilities within the primary instability. The formation of the instabilities is the result of …

SOME MAGNETIC PROPERTIES OF BORE CORE SEDIMENTS
… the North Sea cores. Simulation experiments of shock impact conducted on bore core materials suggests that shock/vibration of the drill barrel is the major process that is responsible for the radial variation in core magnetic properties. Titanomagnetite (including magnetite) and pyrrhotite are …

Steady and Unsteady Heat Transfer in a Film Cooled Transonic Turbine Cascade
The unsteady interaction of shock waves emerging from the trailing edge of modern turbine nozzle guide vanes and impinging on downstream rotor blades is modeled in a linear cascade. The Reynolds number based on blade chord and exit conditions (5*10^6) and the exit Mach number (1.2) are …

Comparison of the Different Hazards Experienced by Pallets During Material Handling
… investigate the intensity of the vibrations and shock impacts that forklifts exert during material handling. Forklifts in multiple facilities were instrumented with Lansmont SAVER 3X90 and 3D15 data loggers to measure the acceleration peak, g of shock impacts, duration of impacts, random …

Investigation into Pallet Durability Throughout the Hazards that Pallets Experience During Regular Use and Handling
… is a key characteristic with significant impact on a company's supply chain. Physical durability is defined as the number of trips that the pallet will accomplish before requiring repairs. Numerous studies have focused on understanding how durability is affected by different pallet …

Price Dynamics in LNG Spot Markets: An Econometric Analysis
… estimation results also display that the price shocks in the Japanese and the Spanish LNG markets have symmetric effects, that is to say, they do not react any differently to the positive news than they do to the negative news. Additionally, the findings suggest that the NBP price and the …

Integrity of packages and contents subject to handling and distribution hazards.
… the possibility of mechanical damage, due to shock, impact and compression. So care must be taken that damage does not occur to both package and contents. The development of analytical and simulation techniques for investigating the dynamic behaviour of a package subject to handling and …

Functionalized silicone composites: omniphobic coatings, microspheres and plastic explosives
… a paucity of literature regarding the controlled shock impact and subsequent detonation of commonly used explosives. What reports exist rely on computer-modelling and idealized assumptions to make conclusions about the thermomechanical and chemical nature of these events. When an actual explosive …

Three essays in environmental health
… focusing on the role played by environmental shocks in determining health outcomes of children exposed to them. In the light of rapid climatic changes affecting human capital, Chapter 1 is one of the first to explore the prenatal channel of exposure to the December 2004 Indian Ocean tsunami, …
