Deep Underground Science and Engineering, EarlyView.Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

Two mining sites, one European (Site A), the first discovered, and the other Aboriginal (Site B), were investigated on the southern spurs of the Gog Ranges in north-central Tasmania, about 3 km north as the crow flies from Mole Creek, the nearest town (Figs 1, 6, 7; see Introduction). Situated at altitudes of 230 m (Site A) and 340 m (Site B) above sea

Science, 1971
In a footnote to the review of M. M. Gerasimov's The Face Finder [173, 712 (1971)], the misspelling of Julius Koliman's name is erroneously attributed to a bibliography (1962) by W. M. Krogman. The error occurs in a different authority's work. Kollmann established methods (1898) for building on a skull a face recognizably correct.
