    All is quiet at 10:30 pm until a nurse notices water on the 2nd floor hallway. Building maintenance is called and discovers a ruptured pipe fitting in a bathroom on the 2nd floor. The water is shut off at 10:45 pm but unfortunately the damage has been done. It is later discovered that water penetrated through perforations in the ceiling in the CT suite on the 1st floor exposing the 16-slice CT gantry and patient table to water.

    The role that water plays in our existence is well understood. Without it, most living things will rapidly wither and die. Equally catastrophic of course, are the consequences of too much water. Not only to living things, in terms of widespread flooding, but also in terms of damage to machinery and equipment from exposure to water.

    Is it possible to differentiate between lightning related surges and artificially generated electrical surges?

    E-Discovery is the process of collecting and exchanging electronically stored information (ESI) that is requested during the discovery phase in civil litigation.

    Rail residual stress distributions can be complex and variable in nature, as different manufacturing techniques produce varying stress magnitudes and distributions. To evaluate the effect of residual stresses on rail integrity, an analysis technique was sought that could quantify the effect of these stresses on web crack propagation.

    The computer program LS-DYNA3D was used to simulate the behavior of a specific, though representative, heavy truck cab-over tractor-trailer vehicle during a full 180° rollover event. These simulations provide a key component in the development of a physical testing procedure for evaluating structural integrity and occupant crash protection system designs in heavy trucks.
