due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. the temperature effect on the swelling properties of commercial polyacrylic acid (paa) hydrogel beads was investigated as a function of time and temperature. gel bead size, swelling equilibr...

The accuracy of joint angle measurement of the hand may be negatively influenced by joint swelling, deformation and other obstacles. We developed an alternative goniometer with clear ergonomic advantages, especially for the measurement of small joints. This new concept of goniometry is described and preliminary results on the reliability of the measurements are presented. The intraclass correla...

introduction: the aim of this study was to assess the effect of low-level laser therapy (lllt) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. methods: a prospective, randomized double-blind study was undertaken on 44 patients at the dental school, ahvaz jundishapur university of medical sciences, in 2015. a low-level laser was randomly applied on one of ...

Most studies on hydrogel swelling instability have been focused on a constrained boundary condition. In this paper, we studied the mechanical instability of a piece of disc-shaped hydrogel during free swelling. The fast swelling of the gel induces two swelling mismatches; a surface-inner layer mismatch and an annulus-disc mismatch, which lead to the formation of a surface crease pattern and a s...

expansible soils are those which will suffer considerable swelling and volume change when subjected to water. the resulting swelling pressure may cause complete destruction of such light structures as irrigation canal linings, floor slabs, etc. based upon previous investigations, swelling of clayey soils has been blamed for failure of many irrigation canals in iran and in other countries of the...

soil is known as the base material for many structure, on the other hand, some soils cause problems for some structures such as roads. some types of soils absorb moisture and swell then they may shrink when losing water. the changes of moisture in these soil samples cause changes their volume and pressure to layers of the pavement and eventually leads to destruction of roads. therefore, it is n...
