    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.

    3/14/2013 · Corrosion
    An ominous cloud of smoke continues to billow as the sprinklers rain water throughout the facility. The production manager's mechanical and electrical equipment is rapidly deteriorating, and within hours, the previously pristine equipment normally used to manufacture precision circuit boards will have a thin coating of flash rust with further damage forthcoming.

    1/25/2013 · Damages
    Doctors and nurses need to make quick, educated decisions to minimize the impact of difficult situations. These decisions are based on the practitioner's years of experience, their education, the science and technology available, and with the assistance of critical analytical and diagnostic equipment.

    11/19/2012 · Damages
    A water pipe breaks in a healthcare provider's facility, saturating an MRI control cabinet. The manufacturer is called in and spends $200,000 on attempted repairs. The unit still doesn't work. The manufacturer says the entire unit needs to be replaced, at a cost of $240,000.

  • A cracked XXXXX polymer filament die plate was received for analysis to determine the cause of cracking. Results indicate the die plate cracked as a result of a brittle nitrided case and an insufficient cross-sectional area of the narrow ligament between the cap screw hole and the heater cartridge hole on the inlet face.

    6/14/2013 · Metallurgy
    Two cores from a marine diesel engine oil cooler were received for analysis to investigate the cause of failure via leaking. Results indicate that the cooler core failed due to pitting corrosion initiated on the interior (oil side) at the edge of the fins.

    3/11/2013 · Failure Analysis
    A fractured input shaft used in NASCAR racing was received for analysis to investigate the cause of failure. Results indicate the shaft fractured due to fatigue progression from an intergranular stress crack, initiated at a dot peen identification marking on the shaft.

    1/16/2013 · Failure Analysis
    A cracked nozzle sleeve stub from XXXX Vessel of the proprietary vaporizer system was analyzed to determine the cause of cracking.

    11/7/2012 · Failure Analysis
    Two blade samples of a cracked ******************* centrifugal blower impeller blade was submitted for metallurgical analysis of the cracks. The cracks in the submitted blade samples were found to have initiated at corrosion pits on the leading edge of the blades.

    8/28/2012 · Failure Analysis
    Two aluminized heater tubes were received for analysis to investigate the cause of failure. Unused tube material also was supplied for comparison. Results indicate that the tubes failed via hot oxidation corrosion at extreme temperatures.

    6/22/2012 · Failure Analysis
    Metallurgical Technologies, Inc. examined a failed superheater tube from XXXXXX X XXX Boiler #7. The ASME SA-213 Grade T11 tube had been in service for 6 to 8 years until failure. The mode of failure was short-term stress rupture due to significant overheating.

    4/17/2012 · Metallurgy
    The four seized bearings submitted for metallurgical analysis were determined to have suffered deterioration of their grease to the point that it was inhibiting motion rather than enabling. The grease had turned to a thick (viscous) black sludge that was full of particulate. Electrical pitting was found in the seized bearings, especially the inner races. Signs of axial (thrust) loads were noted, mainly in the outer raceways. Larger arc strike regions were found on the balls.

    3/13/2012 · Failure Analysis
    A cracked 316Ti stainless steel preheater tube was analyzed to determine the failure mechanism. A second non-cracked tube section from a different elevation was also analyzed to determine the condition of the tube material.

    9/1/2011 · Metallurgy
    A welded left front spindle/steering arm assembly that had fractured at the fillet weld joint between the steering arm and inner brake boss was received for analysis to determine the mode of failure.

    6/6/2011 · Metallurgy
    Several concentrating still condenser tubes exhibiting pitting were received to determine the cause of pitting. Results indicate the tubes pitted initially from the inner diameter (ID) surface due to microbiological corrosion (MIC). MIC pitting initiated preferentially at the tube seam weld. Additional ID surface pits and significant pit enlargement of MIC pits due to chloride pitting were also observed. The chlorine is likely remains from the hydrochloric cleaning process

    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.
