In the separation process, it has been thought that the species present at low levels of acidity are simple metal co-ordination compounds. However, our own structural studies on a number of terdentate ligands have shown a large variety of structural types which depend on the nature of the ligand and on the lanthanide concerned. In order to gain insights into the coordinative mechanism of extrac...

For every central element z of a lattice effect algebra E, the interval [0, z] with the ⊕ operation inherited from E and the new unity z is a lattice effect algebra in its own right. We show connections between blocks, sharp elements and central elements of [0, z] and those of E. We prove that except for central elements, the intervals [0, z] are closed with respect to the ⊕-operation also for ...

The symmetric coupling of mixed nite element and boundary element methods is analysed for a model interface problem with the Laplacian. The coupling involves a further continuous ansatz function on the interface to link the discontinuous displacement eld to the necessarily continuous boundary ansatz function. Quasi-optimal a priori error estimates and sharp a posteriori error estimates are esta...

Abstract. Understanding diagenetic reactions in accreted sediments is critical for establishing the balance of fluid sources and sinks accretionary prisms, which turn important assessing pressure field ability faults to host seismic slip. For this reason, we studied deformation bands (shear zones veins) within deep mud from Nankai prism (SW Japan) drilled at site C0001 during IODP Expedition 31...

Reactive porous or focused melt flows are common in crystal mushes of mid-ocean ridge magma reservoirs. Although they exert significant control on magmatic differentiation, their role metal transport between the mantle and ocean floor remains poorly constrained. Here we aim to improve such knowledge for oceanic crust formed at slow-spreading centers (approximately half present-day crust), by fo...

In this article, in order to demonstrate the pragmatic elements of Rawls’s viewpoint, the developmental path of his A Theory of Justice shall first be investigated. This development has two phases: In the first phase, justice has an ethical-philosophical basis. In A Theory of Justice, this phase is specifically shown under the title of theory of justice. In the second phase, justice has no phil...
