Abstract Odontomas are the most common type of odontogenic tumors, which are often discovered by routine radiographic images or after taking films to determine the main cause of the tooth failure eruption or malocclusion. The present study aimed to describe a case of misdiagnosis and similarity of foreign body density in the radiographic appearance to odontoma in a 13-yea...

Unreinforced concrete pipes basically can fail in two modes: beam failure and ring failure. According to the existing test data, the nom· inal stress at beam failure is much less than that at ring failure. Fur· thermore, the nominal stress for either failure mode decreases as the pipe diameter or thickness increases. These size effects can be de· scribed in a unified manner by means of the rece...

Unreliable failure detectors are abstract devices that, when added to asynchronous distributed systems, allow to solve distributed computing problems (e.g. Consensus) that otherwise would be impossible to solve in these systems. This paper focuses on two classes of failure detectors defined by Chandra and Toueg, namely, the classes denoted 3P (eventually perfect) and 3S (eventually strong). Bot...

Adenoviruses are a common cause of respiratory infection, pharyngitis, and conjunctivitis in infants and young children. They are known to cause hepatitis and liver failure in immunocompromised patients; they are a rare cause of hepatitis in immunocompetent patients and have been known to cause fulminant hepatic failure. We present a 23-month-old immunocompetent infant who presented with acute ...

Life threatening hyperkalaemia (> 7.0 mmol/l) is commonly associated with acute renal failure. Moderate hyperkalaemia (6.1-6.9 mmol/l) is also common and well tolerated in patients with chronic renal failure. Renal failure is the most common cause of hyperkalaemia although other causes to consider include drugs (potassium sparing diuretics, angiotensin converting enzyme inhibitors), hyperglycae...

Progressive collapse is a situation where local failure of a primary structural component leads to the collapse of adjoining members which, in turn, leads to additional collapse. Hence, the total damage is disproportionate to the original cause. The most common local failure in framed structure is assumed to be column failure. In this paper, a new approach for dynamic column removal in framed s...

In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

The Federal Aviation Administration (FAA) has been developing the Integrated Safety Assessment Model (ISAM) to provide a baseline risk assessment for the National Airspace System and to evaluate the safety impact of proposed changes to the system. ISAM consists of a set of event sequence diagrams and underlying fault trees for various accident scenarios. In the current model, all basic events i...
