Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy
(2009)The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particles to energies exceeding 10^12 electron ... -
RAFT polymerization in supercritical carbon dioxide based on an induced precipitation approach: synthesis of 2-ethoxyethyl methacrylate/acrylamide block copolymers
(Wiley, 2015-05-13)A new controlled/living heterogeneous polymerization technique using RAFT in benign supercritical CO2 is described involving the formation of monomer-swollen seed particles by precipitation of macroRAFT agent prior to ... -
Rapid and efficient cancer cell killing mediated by high-affinity death receptor homotrimerizing TRAIL variants
(Macmillan Publishers Limited, 2010)The tumour necrosis factor family member TNF-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in a variety of cancer cells through the activation of death receptors 4 (DR4) and 5 (DR5) and is considered ... -
Rapid characterization and quality control of complex cell culture media solutions using Raman spectroscopy and chemometrics
(2010)The use of Raman spectroscopy coupled with chemometrics for the rapid identification, characterization, and quality assessment of Complex cell culture media components used for industrial mammalian cell culture was ... -
A rapid culture independent methodology to quantitatively detect and identify common human bacterial pathogens associated with contaminated high purity water
(BioMed Central, 2015-02-18)Water and High Purity Water (HPW) distribution systems can be contaminated with human pathogenic microorganisms. This biocontamination may pose a risk to human health as HPW is commonly used in the industrial, pharmaceutical ... -
A rapid fluorescence based method for the quantitative analysis of cell culture media photo-degradation
(Elsevier (Science Direct), 2013-11-21)Cell culture media are very complex chemical mixtures that are one of the most important aspects in biopharmaceutical manufacturing. The complex composition of many media leads to materials that are inherently unstable and ... -
Rapid hydrolysis of phosphate monoesters by zirconium(IV) complexes in neutral solution
(2012)Three zirconium(IV) complexes (1-3) with mono- and dinucleating tripodal ligands are reported that promote the hydrolysis of the phosphate monoesters p-nitrophenyl phosphate (NPP) and phenyl phosphate (PP) in neutral ... -
Rapid quantification of tryptophan and tyrosine in chemically defined cell culture media using fluorescence spectroscopy
(2012)The rapid and inexpensive analysis of the complex cell culture media used in industrial mammalian cell culture is required for quality and variance monitoring. Excitation-emission matrix (EEM) spectroscopy combined with ... -
Rapid screening for specific glycosylation and pathogen interactions on a 78 species avian egg white glycoprotein microarray
(Nature Research, 2017-07-25)There is an urgent need for discovery of novel antimicrobials and carbohydrate-based anti-adhesive strategies are desirable as they may not promote resistance. Discovery of novel anti-adhesive molecules from natural product ... -
Rapid unwinding of triplet repeat hairpins by Srs2 helicase of Saccharomyces cerevisiae
(2008)Expansions of trinucleotide repeats cause at least 15 heritable human diseases. Single-stranded triplet repeat DNA in vitro forms stable hairpins in a sequence-dependent manner that correlates with expansion risk in vivo. ... -
Rate constant calculations of H-Atom abstraction reactions from ethers by H(O) over dot(2) radicals
(American Chemical Society, 2014-01-31)In this work, we detail hydrogen atom abstraction reactions from six ethers by the hydroperoxyl radical, including dimethyl ether, ethyl methyl ether, propyl methyl ether, isopropyl methyl ether, butyl methyl ether, and ... -
Rational Generalised Moonshine from Abelian Orbifoldings of the Moonshine Module
(2001)We consider orbifoldings of the Moonshine Module with respect to the abelian group generated by a pair of commuting Monster group elements with one of prime order $p=2,3,5,7$ and the other of order $pk$ for $k=1$ or $k$ ... -
Ray W Ogden: An Appreciation
(SAGE Publications, 2015-07)This special issue of Mathematics and Mechanics of Solids is dedicated to Professor Ray Ogden FRS on the occasion of his 70th birthday. It is a companion volume to another special issue edited by our colleagues ... -
Rayleigh waves and surface stability for Bell materials in compression; comparison with rubber
(Oxford University Press, 2003)The stability of a Bell-constrained half-space in compression is studied. To this end, the propagation of Rayleigh waves on the surface of the material when it is maintained in a static state of triaxial prestrain is ... -
Rayleigh waves in anisotropic crystals rotating about the normal to a symmetry plane
(American Society of Mechanical Engineers, 2004)The propagation of surface acoustic waves in a rotating anisotropic crystal is studied. The crystal is monoclinic and cut along a plane containing the normal to the symmetry plane; this normal is also the axis of rotation. ... -
Rayleigh waves in symmetry planes of crystals : explicit secular equations and some explicit wave speeds
(Elsevier, 2003)Rayleigh waves are considered for crystals possessing at least one plane of symmetry. The secular equation is established explicitly for surface waves propagating in any direction of the plane of symmetry, using two different ... -
An RCM experimental and modeling study on CH4 and CH4/C2H6 oxidation at pressures up to 160 bar
(Elsevier, 2017-06-13)The oxidation of CH4 and CH4/C2H6 mixtures were studied at pressures relevant to knocking in large bore natural gas engines. The experiments were carried out in a rapid compression machine (RCM) at end of compression (EOC) ... -
Real-time quantitative visualization of 3D structural information
(Optica, 2012)We demonstrate a novel approach for the real time visualization and quantification of the 3D spatial frequencies in an image domain. Our approach is based on the spectral encoding of spatial frequency principle and permits ... -
Realizing a fusion system by a single finite group
(2010)We show that every saturated fusion system can be realized as a full subcategory of the fusion system of a finite group. The result suggests the definition of an 'exoticity index' and raises some other questions which we discuss.
