A statistical investigation into relationships between the IIE irons and the ordinary, F and “HH” chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 10, Page 2376-2400, October 2025.
Abstract It has been proposed that IIE iron meteorites formed through impact processes on a parent body that was composed of either the H chondrites or a much‐debated fourth ordinary chondrite group, the HH chondrites. To resolve this debate, we have compiled a large dataset for the ordinary chondrites, low‐fayalite ungrouped chondrites, and IIE irons,

Accelerated Aging, Debilitation, Slow Death, and the Multiple Temporalities of Aging Incarcerated Persons: A Philip K. Dickian Science Fiction Examination

open access: yesNursing Inquiry, Volume 32, Issue 4, October 2025.
ABSTRACT Prisons are debilitating and disorienting spaces. Temporal realities themselves are altered from those of the outside world. This paper builds upon a study of prison staff work with aging incarcerated persons in Canadian federal penitentiaries, wherein the prison environment itself contributes to accelerated aging and slow death ...

Atmospheric H2O and the search for Martian brines [PDF]

open access: yes
Abundant martian brines would have important implication for current theories of volatile migration on Mars, since, although the presence of metastable brines is quite plausible, any brine in the reasonably near-surface should be completely depleted on a

Theoretical researches into planetary atmospheres and their influence upon surface features [PDF]

open access: yes
The interface between certain geological and atmospheric phenomena on Mars was studied by examining those geological features which are associated with the presence of water in the liquid or solid phases.

The spectroscopic, chemical, and photophysical properties of Martian soils and their analogs (MERC, phase 2) [PDF]

open access: yes
A series of variably proportioned iron/calcium smectite clays and iron loaded smectite clays containing iron up to the level found in the Martian soil were prepared from a typical montomorillonite clay using the Banin method.
