Sentence examples for joint persistence from inspiring English sources

Impersistent joints, which are not continuous on a joint plane, can be accommodated [Pariseau WG. Effects of joint persistence on jointed rock masses. Trans Soc Min Metal Explor 2003 314:121–8].

Both coplanar jointed rocks with different joint persistence and non-coplanar ones with different joint inclinations were simulated and investigated numerically.

The results show that for coplanar jointed rocks, the peak shear stress decreases nonlinearly with the joint persistence, and the failure process can be divided into four stages: elastic shearing phase, crack propagation, failure of rock bridges, and residual phase.

Additionally, damage to the shear modulus is related to the initial damage conditions and joint persistence of the samples.

However, slope stability analysis of a large, deep copper mine indicated a need for computational efficiency even in two-dimensional analysis of vertical sections through pit walls [Puri S. Role of joint persistence in rock slope stability. MS thesis, Department of Mining Engineering, University of Utah, 2006].

In this paper the effect of seven parameters, the compressive strength of intact rock (UCS), joint orientation, joint persistence, joint density (P32), joint friction, confined stress and hydraulic radius (HR), is investigated using numerical technique named the Synthetic Rock Mass (SRM).

Significant differences in joint spacing, persistence of discontinuities and block size were found between the Australian and Welsh study sites.

The present study addresses the question of reproducibility of survivin status in consecutive tests of RA patients and the value of repeated survivin testing for prediction of joint damage, persistence of disease activity, functional disability and pain.

In patients with RA, several studies have documented significant but variable depletion of B cells in samples of synovial tissue of involved joints and persistence of CD20- plasma cells [ 66- 68].

Human ASC injected into unimpaired mouse knee joints showed long-term persistence in joint tissue in 60% of all mice up to 186 days after injection, but a substantial fraction of ASC seemed to have migrated to the bone marrow, adipose tissue and muscle.

We propose that Th17 plasticity contributes to the persistence of joint inflammation by augmenting local levels of GM-CSF.
