Further, the weathering coefficient (Wc) determined by Schmidt hammer was considered as an alternative parameter for the determination of the rating for joint weathering.
For instance, dissolution, faulting, shearing, columnar jointing, weathering, and hydrothermal alteration usually increase the rock porosity and fluid permeability, and hence lower resistivity.
Bedrock that has been fractured into series of parallel joints can weather into high rock walls known as fins.
On the other hand, if the pipe is made from another material, like clay tile, you should seal the joint with weather-proof silicone caulk.
Total of eight specimens in three groups, according to whether there is a butt-joint or weathering period, are tested respectively for both 5 h and 9 h.
They are not inherently permeable but have secondary permeability or porosity developed as a result of fracturing, jointing and weathering, which may give rise to groundwater occurrence (Ahmed et al. 1977).
To examine differences in self-reported joint pain between weather-sensitive and non-weather-sensitive people with clinical OA, an independent sample t-test was performed.
This study aimed to examine whether there are differences in perceived joint pain between weather-sensitive and non-weather-sensitive people with OA in six European countries with different climates and to identify characteristics of older persons with OA that are most predictive of self-perceived weather sensitivity.
The specific objectives of the present study are: (1) to examine whether there are differences in perceived joint pain between weather-sensitive and non-weather-sensitive people with OA in six European countries with different climates; and (2) to identify characteristics of older persons with OA that are most predictive of perceived weather sensitivity.
When I am out of joint, from bad weather or a poor run of thoughts, I like to sit and think about Edward Howe Forbush.
