BLOCKAGE 2.5 user`s manual

Abstract

Portions of this document may be illegible AbstractThe BLOCKAGE 2.5 code described in t h i s User's Manual was developed by the United States Nuclear Regulatory Commission (NRC) as a tool to evaluate licensee compliance with NRC Bulletin 96-03, "Potential Plugging of Emergency Core Cooling Suction Strainers by Debris in Boiling Water Reactors". As such, BLOCKAGE 2.5 provides a generalized framework into which a user can input plant-specific and insulationspecific data for performing analyses in accordance with Regulatory Guide 1.82, Rev. 2. This user's manual describes the capabilities of BLOCKAGE 2.5 along with a description of the graphics user's interface provided for data entry. Each input/output dialog is described in detail along with special considerations related to developing and executing BLOCKAGE. Also, several sample problems are provided such that user can easily modlfy them to suit a particular plant of interest. The models used in BLOCKAGE 2.5 and their validation are presented in the accompanying NUREG/CR-6371.The BLOCKAGE models were designed to be parametric in nature, allowing the user flexibility to examine the impact of several modeling assumptions and to conduct sensitivity analyses. As a result, BLOCKAGE 2.5 results are known to be very sensitive to the user provided input. It is therefore strongly recommended that users become thoroughly familiar with BLOCKAGE models and their limitations as described in NUREG/CR-6224.iii

Levator ani muscle morphology and function in women with obstetric anal sphincter injury

“…Pelvic floor muscle exercise is recommended as first-line treatment for women with prolapse and incontinence symptoms 8,9 . The effects of exercise for the prevention and treatment of incontinence in antenatal and postnatal women is less clear, and it is possible that some subgroups of women may benefit more from training 10 .…”

Towards a revision of Ameira Boeck, 1865 (Harpacticoida, Ameiridae): re‐examination of the A. tenella‐group and the establishment of Filexilia gen. n. and Glabrameira gen. n.

“…The species was rediscovered by Por (1964b) who described both sexes and transferred it to Sicameira. Currently, Sicameira encompasses four interstitial species, all described from coarse sandy sediments in intertidal or shallow subtidal localities (Scott 1896;Klie 1950;Rao 1972;Marinov 1973). A key to the species is provided below: I. P2-P3 exp-3 with inner seta Klie (1950) did not discuss the relationships of his new genus.…”
