The subgroup measuring the defect of the Abelianization of SL_2(Z[i])
(Springer, 2013-02-10)There is a natural inclusion of SL2(Z) into SL2(Z[i]) , but it does not induce an injection of commutator factor groups (Abelianizations). In order to see where and how the 3 -torsion of the Abelianization of SL2(Z) ... -
Sulfamerazine: Understanding the influence of slip planes in the polymorphic phase transformation through X-ray crystallographic studies and ab initio lattice dynamics
(American Chemical Society, 2015-08-28)Understanding the polymorphism exhibited by organic active-pharmaceutical ingredients (APIs), in particular the relationships between crystal structure and the thermodynamics of polymorph stability, is vital for the ... -
Summertime primary and secondary contributions to Southern Ocean cloud condensation nuclei
(Nature Research (part of Springer Nature), 2019-07-18)Atmospheric aerosols in clean remote oceanic regions contribute significantly to the global albedo through the formation of haze and cloud layers; however, the relative importance of ‘primary’ wind-produced sea-spray over ... -
Super stable fluorescein isothiocyanate isomer I monolayer for total internal reflection fluorescence microscopy
(American Chemical Society, 2018-08-27)Total internal reflection fluorescence microscopy (TIRFM) is an important method in surface science and for the analysis of surface-bound macromolecules. Here, we developed and explored the use of a novel fluorescein ... -
Supersonic turbulence in the cold massive core JCMT 18354-0649S
(2009)An example of a cold massive core, JCMT 18354-0649S, a possible high mass analogue to a low mass star forming core is studied. Line and continuum observations from JCMT, Mopra Telescope and Spitzer are presented and modelled ... -
Supramolecular stacking in a high Z′ calix[8]arene–porphyrin assembly
(Royal Society of Chemistry, 2019-11-15)A co-crystal structure of sulfonato-calix[8]arene (sclx8) and trimethylanilinium-porphyrin (tmap) at 1.0 Å resolution is reported. The oppositely charged macrocycles formed an alternating stacked assembly. Crystal packing ... -
Supramolecular Structures and Tautomerism of Carboxylate Salts of Adenine and Pharmaceutically Relevant N-6-Substituted Adenine
(2011)Co-crystal and salt formation of the kinetin analogue N-6-benzyladenine with the pharmaceutically acceptable co-crystal and salt formers maleic acid, oxalic acid, glutaric acid, succinic acid, benzoic acid, and fumaric ... -
Surface acoustic waves in rotating orthorhombic crystals
(The Royal Society, 2004-02-08)The propagation of surface (Rayleigh) waves over a rotating orthorhombic crystal is studied. The crystal possesses three crystallographic axes, normal to the symmetry planes: the half¿space is cut along a plane normal to ... -
Surface enhanced Raman scattering for narcotic detection and applications to chemical biology
(Elsevier, 2005)Raman spectroscopy is rapidly finding favour for applications in the life science because of the ease with which it can be used to extract significant data from tissue and cells. However, the Raman effect is an inherently ... -
Surface stability of nonlinear magnetoelastic solids
(Wiley, 2007-12)The present paper proposes to identify surface stability when a magnetoelastic half-space is subjected to a pure homogeneous pre-deformation and to a magnetic field normal to its (plane) boundary. Clearly, the aim is to ... -
Surface waves and surface stability for pre-stretched, unconstrained, non-linearly elastic half-space
(Elsevier, 2009-06)An unconstrained, non-linearly elastic, semi-infinite solid is maintained in a state of large static plane strain. A power¿law relation between the pre-stretches is assumed and it is shown that this assumption is well ... -
Surface waves in a deformed isotropic hyperelastic material subject to an isotropic internal constraint
(Elsevier, 2004)An isotropic elastic half-space is prestrained so that two of the principal axes of strain lie in the bounding plane, which itself remains free of traction. The material is subject to an isotropic constraint of arbitrary ... -
Surface waves in a stretched and sheared incompressible elastic material
(2005)In this paper, we analyze the effect of a combined pure homogeneous strain and simple shear in a principal plane of the latter on the propagation of surface waves for an incompressible isotropic elastic half-space whose ... -
Surface waves in deformed Bell materials
(2003)Small amplitude inhomogeneous plane waves are studied as they propagate on the free surface of a predeformed semi-infinite body made of Bell constrained material. The predeformation corresponds to a finite static pure ... -
Surface waves in orthotropic incompressible materials
(Acoustical Society of America, 2001-04-17)The secular equation for surface acoustic waves propagating on an orthotropic incompressible half-space is derived in a direct manner, using the method of first integrals. -
Surfactant behaviour of metallacarboranes. A study based on the electrolysis of water
(Royal Society of Chemistry, 2013-11-21)[3,3′-Co(1,2-C2B9H11)2]−, [1]−, and its chloroderivatives have been described as displaying surfactant/aggregation properties. We have studied their behaviour as electrolytes in the water electrolysis process. The electrolysis ... -
SV40 T antigen helicase domain regions responsible for oligomerisation regulate Okazaki fragment synthesis initiation
(Wiley Open Access and Federation of European Biochemical Societies, 2022-01-24)The initiation of Okazaki fragment synthesis during cellular DNA replication is a crucial step for lagging strand synthesis, which is carried out by the primase function of DNA polymerase ¿-primase (Pol-prim). Since cellular ... -
SV40 T antigen interactions with ssDNA and replication protein A: a regulatory role of T antigen monomers in lagging strand DNA replication
(Oxford University Press (OUP), 2020-03-04)DNA replication is a central process in all living organisms. Polyomavirus DNA replication serves as a model system for eukaryotic DNA replication and has considerably contributed to our understanding of basic replication ... -
Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety
(Elsevier, 2009-11-20)The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ... -
