One patient had 4 mm of erosion into the trapezium without symptoms 8 years after surgery.
The capability of the PEEP approach to enhance temporal resolution of monitoring is demonstrated by the determination of the timing of the 100-mm bank erosion incident to an ' event window ' of 2·75 h: this converts to mean bank erosion rate of 36 mm h−1over the period of inundation.
With optimum laser parameters (power=1 kW; scanning velocity=35 mm/s; spot diameter=2 mm), the cavitation erosion resistance in 3.5 wt.% NaCl solution was improved by 5.8 and 2.2 times compared with that of as-received MAB and nickel aluminium bronze (NAB), respectively.
At SG during a 149-d period in 2008, with an extremely high precipitation total of 2089 mm, the net erosion varied only between −5.6 ± 0.4 and −6.5 ± 0.4 kg m−2 and the sediment delivery ratio between 70 and 86% for 10, 15 and 18 m barrier spacings.
Similarly, the medial conjunctiva of the left eye demonstrated a 2.5×× 1 mm region of conjunctival erosion and scleral melting, associated with calcium deposits (Figures 2 and 3).
In the right medial conjunctiva, there was a 2 × 1 mm region of conjunctival erosion with fluorescein uptake associated with scleral thinning and calcium deposits (Figure 1).
A protrusion approximately 0.3 mm wide from the erosion crater was identified by both techniques and is indicative of the fidelity of the technique.
Additionally, in the Conn toolbox, subjects' anatomical T1-weighted images are segmented for grey matter, white matter and cerebrospinal fluid (CSF), and eroded (one-voxel erosion; 2 mm isotropic voxel size) to later remove temporal confounds related to these tissue types (see below).
Large erosions (>1.9 mm) were found to be specific for RA.
Ultrasound has proven to be three times more sensitive than plain films in the detection of bone erosions <2 mm (P < 0.001) [ 29].
