The Kulanaokuaiki Tephra Unit 3 (900 C.E.) was a subplinian basaltic scoria eruption, the largest known to have occurred at Kīlauea’s summit. The initiation mechanism and cause(s) of this highly hazardous eruption remain poorly understood, particularly as this style of activity has not been observed in the modern period. We use olivine diffusion timescales from Fe-Mg and lithium zoning to assess magma storage timescales and ev...
Daily Time Series Analysis of Ambient Ozone and Fine Particulate Matter Levels in Corpus Christi, TexasNARA Subscribed
Air pollution represents an environmental health exposure associated with cardiovascular, respiratory, and neurological diseases. The temporal dynamics of key air pollutants, such as ozone (O 3 ) and fine particulate matter (PM 2.5 ), are poorly understood, especially along the Texas industrial coastal region. This study utilizes daily time series analysis to investigate temporal trends in ambient O 3 and PM 2.5 levels across...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Goats are critical in mixed smallholder agricultural systems in lower and middle-income countries, while fleas are important human and animal health concerns around the world. Convenience sampling was used to describe and consider risk factors for flea infestations of peri-urban goats, with the aim of informing the iterative development of animal husbandry and management based control strategies. Seven hundred and ninety-two g...
