The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN

open access: yesHistory, EarlyView.
Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Analyzing LDEX's Current Measurements in Lunar Orbit

open access: yesThe Planetary Science Journal, 2023
The Lunar Dust Experiment (LDEX) on board the Lunar Atmosphere and Dust Environment Explorer mission orbited the Moon from 2014 September to 2015 April and observed a dynamic, permanently present dust cloud produced by continual meteoroid bombardment. In

The velocity of meteoroids [PDF]

open access: yes, 2004
Abstract. Determining the velocity of meteoroids as they enter the Earth’s atmosphere is very important since the value is fundamental in calculating the orbit of the meteoroid and hence eventually its origin. We describe early attempts at this determination and high-light problems that exist today.

The Redemption of a Forgotten War: Korea in Australian Memory and Commemoration

open access: yesAustralian Journal of Politics &History, EarlyView.
ABSTRACT This article examines how the Korean War has been remembered in Australia despite its historically marginal place in the nation's military heritage. By detailing Australian memories of the Korean War across official, quasi‐official, and unofficial histories, it shows that Korea occupied only a minor position in Australia's military imaginary ...

Analysis of radiation and meteoroid satellite data [PDF]

open access: yes, 1972
The data obtained in earth orbit by the Radiation and Meteoroid Satellite (RMS) were interpreted and reduced to a form which will be usable by future space experimenters. The required tasks are detailed.

Formation of plasma around a small meteoroid: 1. Kinetic theory [PDF]

open access: yes, 2017
This article is a companion to Dimant and Oppenheim [2017] https://doi.org/10.1002/2017JA023963.This paper calculates the spatial distribution of the plasma responsible for radar head echoes by applying the kinetic theory developed in the companion ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...
