New approaches to culture and detection of verocytotoxin producing escherichia coli (VTEC) in clinical laboratory diagnosis
VTEC of serogroups other than 0157 have not been studied widely in the UK. These organisms are difficult to isolate and few laboratories investigate faecal specimens for their presence. Due to this the true prevalence and significance of these organisms is unknown. This study describes an …

An Interactive Chemical Equilibrium Solver for the Personal Computer
The Virginia Tech Equilibrium Chemistry (VTEC) code is a keyboard interactive, user friendly, chemical equilibrium solver for use on a personal computer. The code is particularly suitable for a teaching / learning environment. For a set of reactants at a defined thermodynamic state given by a user, …

Nonlinear State Estimation of the Ionosphere as Perturbed by the 2017 Great American Eclipse
… the eclipse path and that the vertical TEC (VTEC) was drastically decreased near and within the eclipse path. The changes in VTEC and altitudes of peak electron density caused by the eclipse leave a lasting effect that alters the density profile for anywhere from 15 minutes to several hours.

Low-Cost Real-Time Precise Point Positioning (PPP) Correction Service with High Availability and Accuracy
… ionospheric Vertical Total Electron Content (VTEC) corrections, while the Slant Total Electron Content (STEC) map and polynomial model are developed for representing regional slant ionospheric and zenith wet tropospheric corrections, respectively. The low-cost real-time PPP correction service …

Versatile, automated sample preparation and detection of contaminants and biological materials
… was designed, in which 102-108 DNA copies of VTEC E.coli were extracted, LAMP-amplified and visually readout within 1.5 hrs. The major contribution of this thesis is the full system integration of versatile, automated sample preparation and detection systems. They offer great flexibility as …

Optimization of automated immunomagnetic separation for the detection of escherichia coli 0157: H7 by quantitative polymerase chain reaction
… the improved protocol, whilst the standard (EPEC/VTEC) protocol had a detection limit of 102 CFU. This study provides an enhanced and reliable sample preparation procedure, which allows detection of Escherichia co/i 0157:1-17 within 10 h, even at significantly low contamination levels. It also …
