There were 108 failures or recurrences in the surgical group, for an overall surgical failure rate of 3.25%; there were 41 technical failures in the varicocele embolization group, for an overall failure rate of 13.05%.[sup.5] These figures are often used to justify surgical correction over the embolization of varicoceles in the management of infertile men.
Factors such as climate, installation practices and soil corrosivity can greatly affect failure rates. Every utility should properly install pipe, regardless of material used.
Women more vulnerable Failure rates in women were higher than those in men regardless oF the implant's head size.
In the UPMC pathology program, when residents scored 90 or more on step 1 of the USMLE, there was a 0% ABP failure rate for first-time test takers.
Other areas with high failure rates include Leeds (67.3 per cent), Bradford (70.2 per cent) and Brentwood, Essex (67.3 per cent).
For example, the manufacturer specifies reduction of failure rate of the certain type of components within the first three years from the moment of publication of help data: [K.sub.[lambda]](l) = 0.9; [K.sub.[lambda]](2) = 0.8; [K.sub.[lambda]](2) = 0.7.
Accordingly, it is expected here, consistent with Benston and Kaufman (1997) and Cebula (1996, 1999), that the bank failure rate was a decreasing function of the implementation of FDICIA provisions, ceteris paribus.
The failure rate and repair rate of components have been considered those of the standard, (*** NTE 005/06/00, 2006) and of the literature (Bendea, 2002).
Assuming the failure time probability density function, f(t), is exponential with constant failure rate, r, the unit's reliability becomes the following:
In clinical studies comprising more than 15,000 women, Natural Cycles had a "perfect use" failure rate of 1.8% and a "normal use" failure rate of 6.5%.
This compares favorably with other forms of contraception and birth control: Male condoms have a perfect use failure rate of 2.0% and a normal use failure rate of 18.0%, and combined oral contraceptives have a perfect use failure rate of 0.3% and a normal use failure rate of 9.0%, according to the Association of Reproductive Care Professionals.
