Accessing the cohomology of discrete groups above their virtual cohomological dimension
Rahm, Alexander D. (2014)We introduce a method to explicitly determine the Farrell-Tate cohomology of discrete groups. We apply this method to the Coxeter triangle and tetrahedral groups as well as to the Bianchi groups, i.e. PSL_2 over the ring ... -
Determination of friction coefficient in unconfined compression of brain tissue
Rashid, Badar; Destrade, Michel; Gilchrist, Michael (Elsevier, 2012-10)Unconfined compression tests are more convenient to perform on cylindrical samples of brain tissue than tensile tests in order to estimate mechanical properties of the brain tissue because they allow for homogeneous ... -
Experimental characterisation of neural tissue at collision speeds
Destrade, Michel; Rashid, Bader; Gilchrist, Michael (International Research Council on Biomechanics of Injury (IRCOBI), 2012)Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... -
Ferromagnetic exchange in a twisted, oxime-bridged [Mn(III)2] dimer
Jones, Leigh F. (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 ... -
Hyperelastic and viscoelastic properties of brain tissue in tension
Destrade, Michel; Gilchrist, Michael D. (ASME, 2012)Mechanical characterization of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... -
Impact of pig slurry amendments on phosphorus, suspended sediment and metal losses in laboratory runoff boxes under simulated rainfall
O'Flynn, C. J.; Healy, Mark G. (Elsevier, 2012)Losses of phosphorus (P) when pig slurry applications to land are followed by a rainfall event or losses from soils with high P contents can contribute to eutrophication of receiving waters. The addition of amendments to ... -
Inhomogeneous deformation of brain tissue during tension tests
Destrade, Michel; Gilchrist, Michael (Elsevier, 2012)Mechanical characterization of brain tissue has been investigated extensively by various research groups over the past 50 years. These properties are particularly important for modeling Traumatic Brain Injury (TBI). ... -
Monitoring cell culture media degradation using surface enhanced Raman scattering (SERS) spectroscopy
Calvet, Amandine; Ryder, Alan G. (Elsevier (Science Direct), 2014-06-13)The quality of the cell culture media used in biopharmaceutical manufacturing is a crucial factor affecting bioprocess performance and the quality of the final product. Due to their complex composition these media are ... -
Old dog, new tricks: 2,2'-biphenol as a bridging and book-end ligand in discrete and extended Co(II) architectures
Berg, Nelly; Jones, Leigh F. (RSC, 2012-02-01)We report the first Co(ii) based discrete and extended network materials comprising the 2,2[prime or minute]-biphenol ligand. We first present the synthesis and magnetic characterisation of the Co(ii) dinuclear complexes ... -
Temperature effects on brain tissue in compression
Destrade, Michel; Gilchrist, Michael (2012)Extensive research has been carried out for at least 50 years to understand the mechanical properties of brain tissue in order to understand the mechanisms of traumatic brain injury (TBI). The observed large variability ... -
What controls the magnetic interaction in bis-mu-alkoxo Mn(III) dimers? A combined experimental and theoretical exploration.
Berg, Nelly; Jones, Leigh F. (Wiley, 2012-03-29)The synthesis and magnetic characterisation of a series of bis-mu-alkoxide bridged MnIII dinuclear complexes of general formula [MnIII2(mu-OR)2(biphen)2(ROH)x(L)y] (where R=Me, Et; H2biphen=2,2'-biphenol and L=terminally ...
