Potentiometry of Cationic Surfactants

Autor: Gwilym James Moody, J. D. R. Thomas

Publikováno v: Catonic Surfactants ISBN: 9780429270376

The determination of surfactants in a variety of samples is commercially important. The classic method for anionic and cationic surfactants is the two-phase Epton titration. The modifications currently in use are subject to many of its disadvantages:

Functional Morphology of the Forelimb of the Nine-Banded Armadillo (Dasypus novemcinctus): Comparative Perspectives on the Myology of Dasypodidae

Autor: Michael T. Butcher, Rachel A. Olson, Z. D. Glenn, D. R. Thomas, M. D. Womble

Publikováno v: Journal of Mammalian Evolution. 23:49-69

The nine-banded armadillo, Dasypus novemcinctus, is a member of the family Dasypodidae, which contains all extant species of armadillos and represents the most diverse group of xenarthran mammals by their speciation, form, and range of scratch-diggin

CO2 and CH4 in sea ice from a subarctic fjord under influence of riverine input

Autor: Søren Rysgaard, Nicolas-Xavier Geilfus, D. R. Thomas, O. Crabeck, Bruno Delille, Jean-Louis Tison

Publikováno v: Biogeosciences. 11:6525-6538

We present the CH4 concentration [CH4], the partial pressure of CO2 (pCO2) and the total gas content in bulk sea ice from subarctic, land-fast sea ice in the Kapisillit fjord, Greenland. Fjord systems are characterized by freshwater runoff and riveri

'First 'in situ' determination of gas transport coefficients (D-O2, D-Ar, and D-N2) from bulk gas concentration measurements (O-2, N-2, Ar) in natural sea ice'

Publikováno v: Crabeck, O, Delille, B, Rysgaard, S, Thomas, D N, Geilfus, N-X, Else, B & Tison, J-L 2014, ' First in situ determination of gas transport coefficients (DO2, DAr and DN2) from bulk gas concentration measurements (O2, N2, Ar) in natural sea ice ', Journal of Geophysical Research: Oceans, vol. 119, no. 10, pp. 6655-6668 . https://doi.org/10.1002/2014JC009849

We report bulk gas concentrations of O2, N2, and Ar, as well as their transport coefficients, in natural landfast subarctic sea ice in southwest Greenland. The observed bulk ice gas composition was 27.5% O2, 71.4% N2, and 1.09% Ar. Most previous stud
