ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots , aircraft maintenance technicians , and engineers alike.
ATA Spec 100 was originally published in 1956. It established an industry-wide numbering scheme to organize aviation technical documentation as well as content and formatting guidelines for its conventional printed distribution. ATA Spec 2100 focused on electronic data exchange implemented in SGML. iSpec 2200 was first published in 2000.
If the patient is 'low risk' using the CHA 2 DS 2-VASc score (that is, 0 in males or 1 in females), no anticoagulant therapy is recommended. In males with 1 stroke risk factor (that is, a CHA 2 DS 2-VASc score=1), antithrombotic therapy with OAC may be considered, and people's values and preferences should be considered. [24]
The Particular Risk Analysis (PRA) looks for external events which can create a hazard such as a birdstrike or engine turbine burst. The Zonal Safety Analysis (ZSA) looks at each compartment on the aircraft and looks for hazards that can affect every component in that compartment, such as loss of cooling air or a fluid line bursting.
Duke Treadmill Score is one of the tools for predicting the risk of ischemia or infarction in the heart muscle. [1] The calculation is done based on the information obtained from an exercise test by this formula: [citation needed] [exercise duration by Bruce protocol] - [ 5 × (maximal ST elevation or depression)] - [4 × (treadmill angina index)]
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
Stratification (alternatively, flow chart or run chart) The designation arose in postwar Japan , inspired by the seven famous weapons of Benkei . [ 6 ] It was possibly introduced by Kaoru Ishikawa who in turn was influenced by a series of lectures W. Edwards Deming had given to Japanese engineers and scientists in 1950. [ 7 ]
Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
