Development towards a point-of-care system to monitor pregnancy and fertility biomarkers (2015)
Thesis
Wright, K. J. Development towards a point-of-care system to monitor pregnancy and fertility biomarkers. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4217893

The aim of this thesis was to develop a point of care (POC) device that could monitor progesterone and oestriol in saliva. These hormones have a key role to play in both female fertility and pregnancy. Understanding the concentration of progesterone...

Mg/Ca ratios in freshwater microbial carbonates: Thermodynamic, kinetic and vital effects (2014)
Journal Article
Saunders, P., Rogerson, M., Wadhawan, J., Greenway, G., & Pedley, H. (2014). Mg/Ca ratios in freshwater microbial carbonates: Thermodynamic, kinetic and vital effects. Geochimica et cosmochimica acta, 147, 107-118. https://doi.org/10.1016/j.gca.2014.10.014

The ratio of magnesium to calcium (Mg/Ca) in carbonate minerals in an abiotic setting is conventionally assumed to be predominantly controlled by (Mg/Ca)solution and a temperature dependant partition coefficient. This temperature dependence suggests... Read More about Mg/Ca ratios in freshwater microbial carbonates: Thermodynamic, kinetic and vital effects.

Normal lyotropic liquid crystals (in the lamellar or hexagonal phases) are investigated as a route to afford a structured, three-dimensional, quasi-biphasic framework within which electron transfer cascades may be initiated voltammetrically. For mode... Read More about Voltammetry within structured liquid nanosystems: towards the design of a flexible, three-dimensional framework for artificial photosystems.
