Icarus, 369, 114628 (2021), 2021 Boulders on the surfaces of planets, satellites and small bodies, as well as their geological associations, provide important information about surface processes. We analyzed all available images of the surface of Mercury that have sufficient resolution and quality to detect boulders, and we mapped all the boulders observed.

THE PHARMACOLOGY OF MERCURY [PDF]
JAMA: The Journal of the American Medical Association, 1922 A considerable volume of information has been accumulated on the behavior of mercury in the body. Valuable contributions to the pathologic changes produced in the liver, kidney and other organs have also been made by cases of poisoning in man and by experimental studies on animals. Very few reports, however, have appeared on the pharmacologic action of

Vulcan and anomalous displacement of Mercury's perihelion [PDF]
sent to Astrophysics and Space Science 2023, 2022 In this paper, I re-examine the question of a possible explanation of the anomalous advance of Mercury's perihelion by the existence of the hypothetical planet Vulcan proposed by Le Verrier, whose orbit would be located inside the orbit of Mercury. My calculations are focused on the optimization of the orbital parameters of Vulcan in order to explain ...

Solar-wind electron precipitation on weakly magnetized bodies: the planet Mercury [PDF]
A&A 674, A153 (2023), 2022 Mercury is the archetype of a weakly magnetized, airless, telluric body immersed in the solar wind. Due to the lack of any substantial atmosphere, the solar wind directly precipitates on Mercury's surface. Using a 3D fully-kinetic self-consistent plasma model, we show for the first time that solar-wind electron precipitation drives (i) efficient ...

Space Science Reviews, 2007 Mercury’s unusually high mean density has always been attributed to special circumstances that occurred during the formation of the planet or shortly thereafter, and due to the planet’s close proximity to the Sun. The nature of these special circumstances is still being debated and several scenarios, all proposed more than 20 years ago, have been ...

Model Calibration of the Liquid Mercury Spallation Target using Evolutionary Neural Networks and Sparse Polynomial Expansions [PDF]
Nucl. Instrum. Methods Phys. Res. B 525 (2022) 41-54, 2022 The mercury constitutive model predicting the strain and stress in the target vessel plays a central role in improving the lifetime prediction and future target designs of the mercury targets at the Spallation Neutron Source (SNS). We leverage the experiment strain data collected over multiple years to improve the mercury constitutive model through a ...

Journal of the American College of Toxicology, 1983 New findings on the environmental fate of Hg indicate that lakes can be contaminated by long distance transport on mercury vapor in the atmosphere and that higher levels of Me Hg in fish are associated with acidification of lakes and with the creation of hydroelectric reservoirs.

Equilibrium Condensation from Chondritic Porous IDP Enriched Vapor: Implications for Mercury and Enstatite Chondrite Origins [PDF]
Planetary and Space Sciences 59: 1888-1894 (2011), 2023 The origin of Mercury's anomalous core and low FeO surface mineralogy are outstanding questions in planetary science. Mercury's composition may result from cosmochemical controls on the precursor solids that accreted to form Mercury. High temperatures and enrichment in solid condensates are likely conditions near the midplane of the inner solar ...

Carcinogenicity of mercury and mercury compounds.
Scandinavian Journal of Work, Environment & Health, 1993 Mercury and mercury compounds are widely used in modern society, but only sparse data are available on their carcinogenicity. Methylmercury chloride causes kidney tumors in male mice. Mercury chloride has shown some carcinogenic activity in male rats, but the evidence for female rats and male mice is equivocal.

Extreme close encounters between proto-Mercury and proto-Venus in terrestrial planet formation [PDF]
Monthly Notices of the Royal Astronomical Society, June 2020, 2020 Modern models of terrestrial planet formation require solids depletion interior to 0.5-0.7 au in the planetesimal disk to explain the small mass of Mercury. Earth and Venus analogues emerge after ~100 Myr collisional growth while Mercury form in the diffusive tails of the planetesimal disk.
