This study investigated the in vitro effects of ZnO NP and chemical UV filters commonly used sunscreens on the function of immortalised and primary skin cells. ZnO particulates (30 nm, 80 nm and 200 nm) were compared to the chemical UV filters: butylmethoxydibenzoylmethane (BMDBM) ethylhexylmethoxycinnamate (EHMC), ethylhexylsalicylate (EHS), homomenthylsalicylate (HMS) and 4-methylbenzylidenecamphor (MBC). Human epidermal keratinocytes (NHEK), epidermal melanocytes (NHEM), dermal fibroblasts (NHDF) and the immortalised keratinocyte HaCaT cell line were used in this study.

The objective of this thesis is to examine the practice of infrastructure procurement in Australian State Governments in order to analyse how strategic the procurement function is. In doing so this thesis examines how Australian State Government agencies procure infrastructure projects and the extent to which they view the procurement process as an opportunity to deliver more than just a physical facility. This research contributes to both the body of knowledge focused on maximising the impact of public sector expenditure and the practice of infrastructure procurement.
