This study proposes an effective method to inspect inaccessible nuclear power reactor head nozzles using interface waves that propagate along the shrink fit boundary of a reactor head. The reactor head is relatively thick, which makes it difficult to inspect from the outside by conventional ultrasonic testing. However, interface waves can propagate a long distance from a fixed transducer positi...

An analysis of 2 team-organization models when developing consumer-level shrink-wrapped software.

the effects of chemical and physical treatments on the storage life of bitter lemons in jiroft, kerman province, were investigated. after harvesting, the lemons were treated by curing, fungicide, waxed paper, shrink wrap or using a combination of these treatments. the samples were stored in standard citrus fruit boxes for three months at 85-90% relative humidity at a temperature of 3°c. once a ...

I discuss some of the historical circumstances that drove us to use the lattice as a nonperturbative regulator. This approach has had immense success, convincingly demonstrating quark confinement and obtaining crucial properties of the strong interactions from first principles. I wrap up with some challenges for the future.
