In railway safety-related systems, a failure rate per hour shall be used, instead of a probability per duration of operation for purpose of a quantitative safety analysis.
Table6 lists the average food preparation time, the pot size, and the duration of operation for a two-pot cookstove for a family of six.
The "unlimited duration of operation for unattended sensors deployed to detect infrequent but time-critical events," as the researchers describe it, could have plenty of applications beyond security, of course: imagine popping a few of these all over the forests to monitor the movements of herds, or in space to catch rare cosmic events.
Duration of operation (from incision to closure).
Secondary objectives are to examine overall survival, blood loss, duration of operation, requirement for blood transfusion, length of hospital stay, and morbidity rate.
The only outcome assessed, where there was a significant difference, was duration of surgery, with two studies demonstrating a significantly shorter duration of operation time for TTERPT compared with LAPT.
Secondary outcomes were improvement in quality of life and increase in peak urine flow rate (for effectiveness); blood transfusion, urinary incontinence, urinary retention, urethral stricture, urinary tract infection, retrograde (loss of) ejaculation, erectile dysfunction (for morbidity); and duration of operation, length of hospital stay, and need for reoperation (for descriptors of care).
The waiting time for, duration of operation were recorded by the study midwife.
For duration of operation and blood loss, quartiles were used as cutoff points.
In this study, duration of operation was an average of five hours for internal and 3 hours for external hemipelvectomy.
Therefore, matching the smokers with comparable non-smokers based on sex, age, BMI, indication for operation, duration of operation, chemotherapy, radiation and implant at the surgical site prior to implantation would not have changed the results.
