A family of double-bowl pseudo metallocalix[6]arene discs
(RSC, 2010-03-10)We report the synthesis and magnetic characterisation of a series of planar [M7] (M = NiII, ZnII) disc complexes [Ni7(OH)6(L1)6](NO3)2 (1), [Ni7(OH)6(L1)6](NO3)2·2MeOH (2), [Ni7(OH)6(L1)6](NO3)2·3MeNO2 (3), [Ni7(OH)6(L2) ... -
Features and purposes of mathematical proofs in the view of novice students: observations from proof validation and evaluation performances
(2010-12-22)This thesis describes a comprehensive exploratory study of the approaches taken by novice students to the validation and evaluation of mathematical proofs. A theoretical framework based on sociocultural learning theories ... -
Ferromagnetic exchange in a twisted, oxime-bridged [Mn(III)2] dimer
(Royal Society of Chemistry, 2012-05-02)The dimeric complex [MnIII2(Naphth-sao)2(Naphth-saoH)2(MeOH)2][middle dot]4MeOH (1[middle dot]4MeOH), acts as a simple model complex with which to examine the magneto-structural relationship in polymetallic, oxime-bridged ... -
Finite amplitude elastic waves propagating in compressible solids
(2005)The paper studies the interaction of a longitudinal wave with transverse waves in general isotropic and unconstrained hyperelastic materials, including the possibility of dissipation. The dissipative term chosen is similar ... -
Finite amplitude inhomogeneous waves in Mooney-Rivlin viscoelastic solids
(Elsevier, 2004-09)New exact solutions are exhibited within the framework of finite viscoelasticity. More precisely, the solutions correspond to finite-amplitude, transverse, linearly polarized, inhomogeneous motions superposed upon a finite ... -
Finite-amplitude inhomogeneous plane waves in a deformed Mooney-Rivlin material
(Oxford University Press, 2002)The propagation of finite-amplitude linearly-polarized inhomogeneous transverse plane waves is considered for a Mooney-Rivlin material maintained in a state of finite static homogeneous deformation. It is shown that such ... -
Finite-amplitude inhomogeneous plane waves of exponential type in incompressible elastic materials
(Kluwer Academic Publishers, 1999-05)It is proved that elliptically polarized finite-amplitude inhomogeneous plane waves may not propagate in an elastic material subject to the constraint of incompressibility. The waves considered are harmonic in time and ... -
Finite-amplitude Love waves in a pre-stressed neo-Hookean material
(2008)In the context of the non-linear elasticity theory we consider a model for compressible solids called compressible neoHookean material . We show how (exact) finite-amplitude inhomogeneous plane wave solutions and ... -
The First VERITAS Telescope
(2006)The first atmospheric Cherenkov telescope of VERITAS (the Very Energetic Radiation Imaging Telescope Array System) has been in operation since February 2005. We present here a technical description of the instrument and a ... -
FirstNuSTAR observations of MRK 501 within a radio to TeV multi-instrument campaign
(IOP Publishing, 2015-10-10)We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed characterization of the synchrotron peak with Swift and NuSTAR. During ... -
A fluorescence anisotropy method for measuring protein concentration in complex cell culture media
(Elsevier, 2014-03-12)The rapid, quantitative analysis of the complex cell culture media used in biopharmaceutical manufacturing is of critical importance. Requirements for cell culture media composition profiling, or changes in specific analyte ... -
Fluorescence EEM Spectroscopy for Rapid Identification and Quality Evaluation of Cell Culture Media Components.
(Ingenta, 2011-11)The application of fluorescence excitation-emission matrix (EEM) spectroscopy to the quantitative analysis of complex, aqueous solutions of cell culture media components was investigated. These components, yeastolate, ... -
Fluorescence emission from petroleum; a valuable information source for petroleum analysis.
(EniTecnologie, 2004)Despite the fact that most crude oils are dark coloured liquids, many are observed to be strongly fluorescent when illuminated with UV light. This fluorescence, which originates from the presence of aromatic compounds, is ... -
Fluorescence study of bovine serum albumin and Ti and Sn Oxide nanoparticles interactions.
(The Optical Society, 2007)Nanochemistry offers stimulating opportunities for a wide variety of applications in the biosciences. Understanding of the interaction of nanoparticles with biomolecules such as proteins is very important as it can help ... -
Free Bosonic Vertex Operator Algebras on Genus Two Riemann Surfaces I
(2009)We define the partition and $n$-point functions for a vertex operator algebra on a genus two Riemann surface formed by sewing two tori together. We obtain closed formulas for the genus two partition function for the ... -
Free Bosonic Vertex Operator Algebras on Genus Two Riemann Surfaces II
(2011)We continue our program to define and study $n$-point correlation functions for a vertex operator algebra $V$ on a higher genus compact Riemann surface obtained by sewing surfaces of lower genus. Here we consider Riemann ... -
Frequency domain fluorescence lifetime study of crude petroleum oils
(Springer Verlag, 2008-02-01)Frequency domain (FD) fluorescence lifetime data was collected for a series of 20 crude petroleum oils using a 405 nm excitation source and over a spectral range of similar to 426 to similar to 650 nm. Average fluorescence ... -
From icosahedron to a plane flattening dodecaiodo-dodecaborate by successive stripping of iodine
(Wiley, 2012-09-07)It has been shown by electrospray ionization–ion-trap mass spectrometry that B12I122− converts to an intact B12 cluster as a result of successive stripping of single iodine radicals or ions. Herein, the structure and ... -

The Galway astronomical Stokes polarimeter: an all-Stokes optical polarimeter with ultra-high time resolution
(Springer Verlag, 2013-06-28)Many astronomical objects emit polarised light, which can give information both about their source mechanisms, and about (scattering) geometry in their source regions. To date (mostly) only the linearly polarised components ...
