Tide-surge interaction (TSI) is a critical factor in assessing flooding shallow coastal systems, particularly estuaries and harbours. Non-linear interactions between tides surges can occur due to the water depth bed friction. Global investigations have been conducted examine TSI, but its occurrence impact on levels Aotearoa New Zealand (NZ) not extensively studied. Water level observations from...

The penetration result obtained on a filter test stand depends on several factors. Two of these are challenge aerosol size distribution and the particle detector used to measure the particle size and concentration. Some filter testers employ a monodisperse aerosol challenge while others use a polydisperse challenge. Some particle detectors are based on particle counting while others are based o...

Decreased total testosterone (TT) is the recommended metric to identify age-related hypogonadism. However, average TT and the extent to which it varies by age, can vary substantially among different populations. Population-specific reference ranges are needed to understand normal versus abnormal TT levels. Therefore, the goal for this study was to describe androgen concentrations and their corr...
