    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.

    1/14/2014 · Machinery
    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.

  • Genetic evidence in the form of DNA profiles has proven to be a powerful tool in the advance of justice by proving the innocence of accused persons.

    Low speed motor vehicle collisions are a common occurrence. The use of cellular phones, text messaging, and e-mailing while driving has only increased the frequency of low speed motor vehicle collisions. A motor vehicle collision where there is only minor damage to the vehicles may result in personal injury claims for substantial sums.

    10/11/2012 · Toxicogenomics
    In toxic tort litigation, a person is often claiming to have developed cancer or some other serious disease due to having been exposed to a particular substance. Determining if the exposure to the substance was the cause of the disease is often a central focus of the litigation.

    9/26/2012 · Medical
    It is a common error that an attorney retains the wrong type of expert to testify in a lawsuit. This error is particularly common when the expert is a medical specialist. It is widely believed that a medical doctor who specializes in a particular organ system is qualified to formulate opinions and testify as to all issues concerning that organ system.

    3/26/2014 · Warnings & Labels
    In essence, to warn is to place someone on advance notice of a danger or a potential danger. To warn requires that the person or people giving the warning have a superior knowledge of the harm or potential harm compared to the person or people exposed. Further, the person or the people who are warning must also have a superior knowledge of the means of reducing either the likelihood and/or the magnitude of the harm or potential harm as compared with the person or people exposed.

    Air bag control modules utilize complex algorithms to make air bag deployment decisions based on crash severity related to the change in vehicle speed or deceleration over time. Due to the proprietary nature of air bag deployment algorithms, the velocity, acceleration, or displacement thresholds for air bag deployment during a collision are not easily obtained; however, a range of frontal barrier impact speeds and corresponding deceleration and displacement threshold values for air bag deployment can be approximated using known vehicle stiffness-to-weight ratios.

    A favorite of radiology residents and practitioners alike, this book makes it remarkably simple to learn how to perform and interpret CT scans. The completely revised and updated 3rd Edition covers the most recent advances in CT technique, including the use of multislice CT to diagnose chest, abdominal, and musculoskeletal abnormalities, as well as the expanded role of 3D CT and CT angiography in clinical practice.

    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.

    In 2005 a summary of "General Duty Clause" citations issued for ergonomic hazards was published (Purswell & Purswell, 2005). That summary showed that the primary area of ergonomics citation activity under the "General Duty Clause" (paragraph (5)(a)(1) of the OSHAct of 1970) by OSHA to that point had been concentrated in nursing homes, peaking in 2002 and 2003.

    The purpose of the current study was to update and expand upon an earlier study performed to review and categorize OSHA accident investigation records for pedestrian-backing vehicle accidents according to whether the backing vehicle had a backup alarm and whether the alarm was installed and functioning as intended. The current study includes an analysis of additional records as well as the business type (SIC code) of the employer.
