What is the secret mesmerism that death possesses and under the operation of which a modern architect – strident, confident, resolute – becomes rueful, pessimistic, or melancholic?1 Five years before Le Corbusier’s death at sea in 1965, the architect reluctantly agreed to adopt the project for L’Église Saint-Pierre de Firminy in Firminy-Vert (1960–2006), following the death of its original architect, André Sive, from leukemia in 1958.2 Le Corbusier had already developed, in 1956, the plan for an enclave in the new “green” Firminy town, which included his youth and culture center and a stadium and swimming pool; the church and a “boîte à miracles” near the youth center were inserted into the plan in the ’60s. (Le Corbusier was also invited, in 1962, to produce another plan for three Unités d’Habitation outside Firminy-Vert.) The Saint-Pierre church should have been the zenith of the quartet (the largest urban concentration of works by Le Corbusier in Europe, and what the architect Henri Ciriani termed Le Corbusier’s “acropolis”3) but in the early course of the project, Le Corbusier would suffer the diocese’s serial objections to his vision for the church – not unlike the difficulties he experienced with Notre Dame du Haut at Ronchamp (1950–1954) and the resistance to his proposed monastery of Sainte-Marie de la Tourette (1957–1960). In 1964, the bishop of Saint-Étienne requested that Le Corbusier relocate the church to a new site, but Le Corbusier refused and the diocese subsequently withdrew from the project. (With neither the approval, funds, nor the participation of the bishop, by then the cardinal archbishop of Lyon, the first stone of the church was finally laid on the site in 1970.) Le Corbusier’s ambivalence toward the project, even prior to his quarrels with the bishop, reveals...

We provide a taxonomic redescription of the dasyurid marsupial Swamp Antechinus, Antechinus minimus (Geoffroy, 1803). In the past, A. minimus has been classified as two subspecies: the nominate A. minimus minimus (Geoffroy, 1803), which is found throughout much of Tasmania (including southern Bass Strait islands) and A. minimus maritimus (Finlayson, 1958), which is found on mainland Australia (as well as some near-coastal islands) and is patchily distributed in mostly coastal areas between South Gippsland (Victoria) and Robe (South Australia). Based on an assessment of morphology and DNA, we conclude that A. minimus is both distinctly different from all extant congeners and that the two existing subspecies of Swamp Antechinus are appropriately taxonomically characterised. In our genetic phylogenies, the Swamp Antechinus was monophyletic with respect to all 14 known extant congeners; moreover, A. minimus was well-positioned in a large clade, together with all four species in the Dusky Antechinus complex, to the exclusion of all other antechinus. Within A. minimus, between subspecies there were subtle morphological differences (A. m. maritimus skulls tend to be broader, with larger molar teeth, than A. m. minimus, but these differences were not significant); there was distinct, but only moderately deep genetic differences (3.9–4.5% at mtDNA) between A. minimus subspecies. Comparatively, across Bass Strait, the two subspecies of A. minimus are morphologically and genetically markedly less divergent than recently recognised species pairs within the Dusky Antechinus complex, found in Victoria (A. mimetes) and Tasmania (A. swainsonii) (9.4–11.6% divergent at mtDNA)

In this work, we present a finite element formulation for the Saint-Venant torsion and bending problems for prismatic beams. The torsion problem formulation is based on the warping function, and can handle multiply-connected regions (including thin-walled structures), compound and anisotropic bars. Similarly, the bending formulation, which is based on linearized elasticity theory, can handle multiply-connected domains including thin-walled sections. The torsional rigidity and shear centers can be found as special cases of these formulations. Numerical results are presented to show the good coarse-mesh accuracy of both the formulations for both the displacement and stress fields. The stiffness matrices and load vectors (which are similar to those for a variable body force in a conventional structural mechanics problem) in both formulations involve only domain integrals, which makes them simple to implement and computationally efficient.
