Let F ι → E f B be a fibration, we focus on the relation between the homotopy invariants cat E, cat F and cat B. The general formula due to Hardie says that cat E (cat ι + 1) • (cat f + 1) -1; if the fibration is trivial, this upper bound can be replaced by cat F + cat B. In this paper, we introduce
Interstitial pore waters from Ocean Drilling Program (ODP) Sites 1150 and 1151, both penetrating V1200 m of sub-seafloor sediment from the upper Japan Trench forearc, were analyzed for B concentrations and N 11 B isotopes. B concentrations cover a wide range from 329 to 3920 WM (0.8^9.3U seawater) a
