Soluble mineral content of soils using electrical conductivity
… mineral content is made at the point of unsaturation. In the absence of clay, grain size does not affect determination of electrical conductivity for soils. Measurement of the electrical conductivity for a series of dilution ratios provides a reliable means of determining the correct dilution …

Particulate matter formation in spark-ignition engines
… undertaken in order to understand the effects of dilution on measured PM, to examine and model the effect of steady state engine operating conditions on engine-out PM, and to characterize the effect of transient engine conditions on particle growth and dynamics. Particle dynamics in diluted SI and …

A study of hydrogenated nanocrystalline silicon thin films deposited by hot-wire chemical vapour deposition (HWCVD)
… We argue that provided a moderate hydrogen dilution ratio in the monosilane gas and efficient process pressure in the deposition chamber, intrinsic hydrogenated nanocrystalline silicon with photosensitivity better than 102 and most importantly resistant to the Staebler Wronski effect (SWE) …

Comparative evaluation of different extenders of bull semen stored under different conditions
… namely Triladyl, Ham’s F10 and M199 at a dilution ratio of 1:4 (semen:extender), and then stored at controlled room temperature 24 °C. Secondly pooled semen was aliquoted into four groups of Ham’s F10 extender and diluted at a ratio of 1:4, then stored at 24 °C, 17 °C, 12 °C and 5 °C …

Hysteretic properties of a modular positive feedback-based gene amplifier
… placed in solutions of various inducer concentrations and grown to a steady-state level of GFP expression. Cells are then resuspended in solutions of lower inducer concentrations and allowed to reach steady state. Hysteresis is observed if the steady-state GFP level depends on the prior …

Adiposity measures and risk of cardiovascular disease
… (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) with risk of first-onset cardiovascular disease under a range of different circumstances. Methods: This thesis used individual records from the Emerging Risk Factors Collaboration to calculate risk ratios, and measures of discrimination …

Assessment of Tonsil-Oral-Scrubbing (TOSc) to detect PRRSV RNA in sows and application of TOSc for PRRSV dynamics in breeding herds
… TOSc samples from PRRSV negative farms at ratios of 1:3, 1:5, 1:8 and 1:10, respectively. To test the freeze-thaw effect on PRRSV RNA detection, 90 TOSc samples were conveniently collected from endemic herds. Each TOSc sample was mildly vortexed and equally aliquoted into 2 replicates after …
