The ground was composed of clay and soil with a dense covering of tall grasses. The ground surface was very wet but not muddy from water draining from the pond. M. paiwanna was the only form of earthworm found at this locality.Published as part of Tsai, C. - F., Tsai, S. - C. & Liaw, G, 2000, Two new species of protandric pheretimoid earthworms belonging to the genus Metaphire (Megascolecidae: Oligochaeta) from Taiwan, pp. 1731-1741 in Journal of Natural History 34 on pages 1732-1734, DOI: 10.1080/00222930050122156, http://zenodo.org/record/474811

Comments on “Sluggish diffusion in Co–Cr–Fe–Mn–Ni high-entropy alloys” by K.Y. Tsai, M.H. Tsai and J.W. Yeh, Acta Materialia 61 (2013) 4887–4897
No full textThe wrong estimation of the diffusion coefficients following the quasi-binary approach and subsequent analysis by Tsai et al. in Co-Cr-Fe-Mn-Ni high entropy alloy are explained. Since this approach, formulated by the present author before the publication by Tsai et al., has potential to emerge as an efficient technique in multicomponent systems, the correct steps of estimation of the diffusion coefficients are explained in detail. At present state, the diffusion data reported in high entropy alloy Tsai et al. has no significance unless estimated again following the correct steps
