The Non-Organic Theory of the Genesis of Petroleum [PDF]

open access: yesarXiv, 1996
Recent advances in interdisciplinary fields as diverse as astrophysics, cosmogeophysics, nuclear geology, etc. have led to interesting developments in the non-organic theory of the genesis of petroleum. This theory, which holds that petroleum is of an abiogenic primordial origin, provides an explanation for certain features of petroleum geology that ...

Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

open access: yesChemSusChem, EarlyView.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

Seasonal resource selection and movement ecology of free‐ranging horses in the western United States

open access: yesThe Journal of Wildlife Management, Volume 87, Issue 2, February 2023., 2023
Feral horses selected for areas of high herbaceous vegetation and avoided forest but moved to higher elevations in winter. Surface water influenced movement patterns for harem groups, whereas bachelor males moved faster, farther, and were less constrained by water availability than harems. Because of the importance of surface water, strategic placement
