Identifications and quantitative measurements of narcotics in solid mixtures using nearIR Raman spectroscopy and multivariate analysis.
(ASTM International, 1999)Raman spectroscopy offers the potential for the identification of illegal narcotics in seconds by inelastic scattering of light from molecular vibrations. In this study cocaine, heroin, and MDMA were analyzed using nearIR ... 
Impact of pig slurry amendments on phosphorus, suspended sediment and metal losses in laboratory runoff boxes under simulated rainfall
(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 ... 
Improved mathematical and numerical modelling of dispersion of a solute from a continuous source
(2011)We present a refinement of a model due to Mondal and Mazumder [7] for dispersion of fine particles in an oscillatory turbulent flow. The model is based on the timedependent advectiondiffusion equation posed on a ... 
Improved simulation of small electron fields for external beam radiation therapy
(2009)This paper reports on improved simulation of small electron fields from a Siemens Primus linear accelerator. Accelerator simulation was performed using the Monte Carlo user code BEAMnrc. Source and geometry parameters ... 
The incompressible limit in linear anisotropic elasticity, with applications to surface waves and elastostatics
(Elsevier, 2002)[no abstract available] 
Incremental magnetoelastic deformations, with application to surface instability
(Springer, 200801)In this paper the equations governing the deformations of infinitesimal (incremental) disturbances superimposed on finite static deformation fields involving magnetic and elastic interactions are presented. The coupling ... 
Inhibition of Burkholderia multivorans Adhesion to Lung Epithelial Cells by Bivalent Lactosides
(MDPI, 20120824)Burkholderia cepacia complex (Bcc) is an opportunistic pathogen in cystic fibrosis patients which is inherently resistant to antimicrobial agents. The mechanisms of attachment and pathogenesis of Bcc, a group of 17 species, ... 
Inhomogeneous "longitudinal" circularlypolarized plane waves in anisotropic elastic crystals
(S. Hirzel verlag, Ingenta Connect, 2006)Conditions on the elastic stiffnesses of anisotropic crystals are derived such that circularly polarized longitudinal inhomogeneous plane waves with an isotropic slowness bivector may propagate for any given direction of ... 
Inhomogeneous "longitudinal" plane waves in a deformed elastic material
(Springer, 200501)By definition, a homogeneous isotropic compressible Hadamard material has the property that an infinitesimal longitudinal homogeneous plane wave may propagate in every direction when the material is maintained in a state ... 
Inhomogeneous deformation of brain tissue during tension tests
(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). ... 
Inhomogeneous shear of orthotropic incompressible nonlinearly elastic solids: Singular solutions and biomechanical interpretation
(Elsevier, 2009)We present a detailed study of rectilinear shear deformation in the framework of orthotropic nonlinear elasticity, under Dirichlet and mixedboundary conditions. We take a slab made of a soft matrix, reinforced with two ... 
Initial stresses in elastic solids: Constitutive laws and acoustoelasticity
(2011)On the basis of the nonlinear theory of elasticity, the general constitutive equation for an isotropic hyperelastic solid in the presence of initial stress is derived. This derivation involves invariants that couple the ... 
Instabilities in elastomers and soft tissues
(Oxford Journals, 20060915)Biological soft tissues exhibit elastic properties that can be dramatically different from rubbertype materials (elastomers). To gain a better understanding of the role of constitutive relationships in determining material ... 
The integral homology of PSL(2) of imaginary quadratic integers with nontrivial class group
(2011)We show that a cellular complex defined by Flöge allows us to determine the integral homology of the Bianchi groups PSL(2)(O[m]), where O[m] is the ring of integers of an imaginary quadratic number field Q [square root ... 
Interaction of nanoparticles with ideal liquidliquid interfaces
(2009)Using molecular simulations the interaction between a noncharged nanoparticle and an ideal liquidliquid interface is studied. The free energy profile as function of nanoparticleinterface separation is determined using ... 
Interface waves in misoriented prestressed incompressible elastic solids
(Oxford Journals, 20041217)Some relationships, fundamental to the resolution of interface wave problems, are presented. These equations allow for the derivation of explicit secular equations for problems involving waves localized near the plane ... 
Intracellular accumulation of high levels of gammaaminobutyrate by Listeria monocytogenes 10403S in response to low pH: uncoupling of gammaaminobutyrate synthesis from efflux in a chemically defined medium
(American Society for Microbiology, 201006)It is well established that the glutamate decarboxylase (GAD) system is central to the survival of Listeria monocytogenes at low pH, both in acidic foods and within the mammalian stomach. The accepted model proposes that ... 
Investigating the solid state hosting abilities of homo and heterovalent [Co7] metallocalix[6]arenes
(RSC, 2012)A family of homovalent [Co(II)(7)(OH)(6)(L1)(6)](NO3)(2)(1), [(MeOH)(2)subset of Co(II)(7)(OH)(6)(L1)(6)](NO3)(2) (2) (where L1H = 2iminomethyl6methoxyphenol) and heterovalent [(NO3)(2)subset of Co(III)Co(II)(6)(O ... 
Investigating tryptophan quenching of fluorescein fluorescence under protolytic equilibrium
