Plaintiff was admitted to a health care facility with ventricular tachycardia (VT). He had a normal coronary angiography with moderate left ventricular (LV) function and was referred for an implantable cardiac defibrillator (ICD) implant procedure. A diagnosis of right ventricular outflow tract tachycardia was made. He was then admitted for an ablation procedure in March 2005, which was successful. In April 2005, he was readmitted with a further occurrence of tachycardia which required emergency cardio version due to hemodynamic compromise and a temporary pacing wire was placed. There was a further attempt at ablation that was again successful and the LV function noted now to have deteriorated and was noted as having poor functioning. On this basis he was considered a candidate for an ICD implant. There was a further reoccurrence of an episode of ventricular tachycardia (VT) in March and April 2006 which was treated medically and he was discharged.
Read Consulting was asked to determine why a welded chair failed and caused injury to the person sitting in it.
It is essential when beginning a root-cause failure analysis involving metallic materials to collect and maintain the as-found physical evidence properly prior to detailed examinations. This has two objectives. In all cases collecting and protecting the evidence in its undisturbed condition provides the best opportunity to derive meaningful good results from the subsequent analyses. Secondly, in a legal proceeding lack of attention to these matters can produce the accusation of spoilation of evidence. As a minimum this will cause presentation problems for the offending party in the suit. At worst such deficiencies by that party may cause the case to be thrown out.
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 16th Street Mall in downtown Denver, Colorado is a pedestrian and transit mall that extends for more than a mile along 16th Street connecting people to major businesses, hotels, restaurants, and retail. Recently, the street mall pavers have experienced a substantial number of loose and cracked granite pavers. Atkinson-Noland & Associates conducted an extensive investigation at the 16th Street Mall granite tile pavers to determine the causes of distress in the paving system. We also helped develop appropriate solutions to paver debonding, slip-resistance, aesthetics, and maintenance.
Many companies struggle with running their in-house laboratories due to the high fixed costs associated with them. The problem often originates because many company's testing project needs vary over time both in size and importance but the lab itself has large fixed costs regardless of usage. Lab outsourcing is when all or certain testing and analysis functions are done through an independent laboratory instead of being done in-house. This can be done in a variety of areas from R&D, failure analysis, competitive product analysis, to patient litigation support services.
Washing machine failures can create significant damage, exposing insurers and their clients to property damage. These failures often involve a high volume of water and can occur without warning. Through the examination of several hundred washing machines, the DONAN Component Testing Laboratory has identified a statistically significant failure trend in General Electric (GE) washing machines. The amount of water supplied to the tub of the washing machine is controlled by a water valve (solenoid-controlled valve) and pneumatic controls. The washing machine's load selector is a pneumatic pressure switch, which activates and deactivates the water valve.
A significant number of elderly persons experience falls every year. In 2010, 2.3 million nonfatal fall injuries involving elderly people were treated in emergency rooms around the country. In the same year, 21,700 elderly people died as the result of unintentional falls. Falls for elderly people are extremely hazardous as they may not recover from fractures and other injuries.
The root cause of the failure of customer returns of heated automobile rear view mirrors was investigated.
Failure analysis reports are usually created when companies suffer from a manufacturing or product failure and do not know what the cause of the problem or how to fix it.
