Imaging polarimetry of planetary and proto-planetary nebulae [PDF]
, 1997 Optical imaging polarimetry has been performed on a small sample of objects which are associated with that stage of stellar evolution occurring between the Asymptotic Giant Branch and full Planetary Nebula. Three such systems are considered, specifically,

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024
Australian Journal of Social Issues, EarlyView.ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Arthropod-borne disease challenges from planetary warming, urbanization, and migration
Virology JournalAs the world confronts simultaneous climate and health emergencies, the spread of emerging infectious diseases, particularly arboviruses, underscores the intersection of planetary health, global mobility, and disease risk. Viral pathogens like Oropouche,

Angewandte Chemie International Edition, EarlyView.A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Planetary Migration and Plutino Orbital Inclinations
The Astronomical Journal, 2000 I investigate which mechanisms could have acted during Neptune's past radial migration to excite plutino orbital inclinations to their present values. These processes include Kozai resonance and the ν18 secular resonance, both before and after the plutino's capture into the 2 : 3 mean motion resonance with Neptune. In the case that ν18 acted before the

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
