In this paper, we describe an example of a hyperkähler quotient of a Banach manifold by a Banach Lie group. Although the initial manifold is not diffeomorphic to a Hilbert manifold (not even to a manifold modelled on a reflexive Banach space), the quotient space obtained is a Hilbert manifold, which can be furthermore identified either with the cotangent space of a connected component Gr res, (...

Nearly all of the dioxygen which animals and aerobic bacteria use during respiration originates from the photosynthetic oxygen evolving complex (OEC) which is found in the chloroplast thylakoid membranes of higher plants and algae. Four specifically bound Mn are required for OEC activity [l]. These manganese do not exhibit the six line epr spectrum which is characteristic of Mn(IIj in solution,...

Informed by object-oriented and relational perspectives on space, this article argues for morecomplex accounts of architectural and urban problématiques. Starting from Isabelle Stengers’distinction between la ville complexe and la ville compliquée, it discusses the 2010 exhibition“Building for Brussels. Architecture and Urban Transformation in Europe” (BOZAR, Centre ofFine Arts ...

This is a survey of M-regularity and its applications, expanding on lectures given by the second author at the Seattle conference, in August 2005, and at the Luminy workshop " Géométrie Algébrique Complexe " , in October 2005 1 .

Synthetic access has been achieved into high oxidation state Mn/Ca chemistry with the 4 : 1 Mn : Ca stoichiometry of the oxygen-evolving complex (OEC) of plants and cyanobacteria; the anion of (Et(3)NH)(2)[Mn(III)(4)Ca(O(2)CPh)(4)(shi)(4)] has a square pyramidal metal topology and an S = 0 ground state.

Oxygen-enhanced combustion (OEC) is a useful method for improving the efficiency of thermal plants and decreasing greenhouse gas (GHG) emissions. Basic modified burner designs utilizing OEC in aluminum melting process rotary tilting furnace were studied. A combined approach comprising experimental measurement simulation modeling was adopted aimed at assessing GHG emissions production. Reduction...

Exposure of isolated thylakoids or intact plants to elevated temperature is known to inhibit photosynthesis at multiple sites. We have investigated the effect of elevated temperature (40 degrees C) for 24 hr in dark on rice seedlings to characterize the extent of damage by in vivo heat stress on photofunctions of photosystem II (PSII). Chl a fluorescence transient analysis in the intact rice le...

A tropical curve Γ is a metric graph with possibly unbounded edges, and tropical rational functions are continuous piecewise linear functions with integer slopes. We define the complete linear system |D| of a divisor D on a tropical curve Γ analogously to the classical counterpart. We investigate the structure of |D| as a cell complex and show that linear systems are quotients of tropical modul...
