Sensitive and selective quantification of glyphosate and aminomethylphosphonic acid (AMPA) in urine of the general population by gas chromatography-tandem mass spectrometry
(Elsevier, 2020-08-26)Glyphosate is the highest volume herbicide used worldwide, and its main biodegradation product is aminomethylphosphonic acid (AMPA), both are listed as priority substances in the Human Biomonitoring for Europe initiative ... -
Setting epidemiological cut-off values for bacteria isolated from aquatic animals: a toolbox for designing a 96-well plate for microdilution MIC assays
(European Association of Fish Pathologists, 2020-06-02)A workshop was held at the EAFP meeting in Porto to initiate discussion on the design of studies that could generate the data needed to set epidemiological cut-off values appropriate for application to antimicrobial ... -
Shear instability in skin tissue
(Oxford University Press, 2013)We propose two toy-models to describe, predict and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of greatest tension present in human skin by ... -
Simple characterization scheme for optical coherence tomography systems with application to a commercial and a near-isometric resolution fibre-based system
(2021-12-14)Optical Coherence Tomography (OCT) is a rapidly growing imaging modality in biomedical optics. OCT can perform high-resolution, cross-sectional imaging of the microstructure of biological tissues by measuring the coherent ... -
Simple shear is not so simple
(2012-03)For homogeneous, isotropic, non-linearly elastic materials, the form of the homogeneous deformation consistent with the application of a Cauchy shear stress is derived here for both compressible and incompressible materials. ... -
Simplified approach to the prediction and analysis of temperature inhomogeneity in rapid compression machines
(American Chemical Society, 2015-11-03)Substantial progress has been made in understanding and reducing temperature inhomogeneity in rapid compression machines (RCMs) with the help of computational modeling. To date, however, it has not been possible to investigate ... -
Simulation of quantum circuits by low-rank stabilizer decompositions
(Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2019-09-02)Recent work has explored using the stabilizer formalism to classically simulate quantum circuits containing a few non-Clifford gates. The computational cost of such methods is directly related to the notion of s t a ... -
Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
(Society of Photo-optical Instrumentation Engineers, 2017-08-22)A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a fingerprint in-vivo. ... -
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
(2009)We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X-ray data using the XMM-Newton satellite, ... -
A single pulse shock tube study of pentene isomer pyrolysis
(Elsevier, 2020-08-02)A single-pulse shock tube study of the four pentene isomers is carried out at 2¿±¿0.16¿bar and 900¿1600¿K. C1 to C6 species profiles were recorded using gas chromatography mass spectrometry analyses. The species are ... -
A six-compound, high performance gasoline surrogate for internal combustion engines: Experimental and numerical study of autoignition using high-pressure shock tubes
(Elsevier, 2019-10-25)This paper presents experimental and modeling data for the autoignition of a novel, six-component, high performance gasoline surrogate fuel comprising ethanol, n-heptane, i-octane, 1-hexene, methylcyclohexane, and toluene ... -
Size exclusion chromatography for screening yeastolate used in cell culture media
(Elsevier, 2023-09-18)Yeastolate is often used as a media supplement in industrial mammalian cell culture or as a major media component for microbial fermentations. Yeastolate variability can significantly affect process performance, but analysis ... -
Slight compressibility and sensitivity to changes in Poisson's ratio
(2012)Finite element simulations of rubbers and biological soft tissue usually assume that the material being deformed is slightly compressible. It is shown here that, in shearing deformations, the corresponding normal stress ... -
Small amplitude waves and stability for a pre-stressed viscoelastic solid
(Springer, 2009)We study the propagation of small amplitude waves superimposed on a large static deformation in a nonlinear viscoelastic material of differential type. We use bulk waves and surface waves to address the questions of ... -
Small ester combustion chemistry: Computational kinetics and experimental study of methyl acetate and ethyl acetate
(Elsevier, 2018-07-17)Small esters represent an important class of high octane biofuels for advanced spark ignition engines. They qualify for stringent fuel screening standards and could be synthesized through various pathways. In this work, ... -
Snake venom potency and yield are associated with prey‐evolution, predator metabolism and habitat structure
(Wiley, 2019-01-07)Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast ... -
SnCl4- and TiCl4-catalyzed anomerization of acylated O- and S-Glycosides: analysis of factors that lead to higher alpha:beta anomer ratios and reaction rates
(American Chemical Society, 2010-09-13)The quantification of factors that influence both rates and stereoselectivity of anomerization reactions catalyzed by SnCl4 and TiCl4 and how this has informed the synthesis of alpha-O- and alpha-S-glycolipids is discussed ... -
