We investigate the effects of the contact angle θw, and the angle of inclination θ on the interaction between an infinite cylinder and a free fluid-fluid interface governed only by its surface tension. We describe a numerical ...

The retreat history of the West Antarctic Ice Sheet (WAIS) since the Last Glacial Maximum is important for understanding the process of rapid deglaciation, constraining models that seek to predict the future trajectory of ...

Acoustic signals play a fundamental role in avian territory defence and mate attraction. Several studies have now shown that spectral properties of bird song differ between urban and rural environments. Previously this has ...

Steady-state moving Mode-III infinite interfacial crack along the perfect interface in a dissimilar strip is investigated. The crack position is not generally speaking symmetrical with respect to the strip surfaces. Both ...

In mixed-species forests of complex structure, the delineation of tree crowns is problematic because of their varying dimensions and reflectance characteristics, the existence of several layers of canopy (including ...

Recent evaluations of the effectiveness of prison-based cognitive skills training programmes in reducing reconvictions have produced mixed results. The present study adopts a qualitative evaluation methodology in order to ...
