In situ cosmogenic Be exposure dating, radiocarbon determinations, salt and sediment geochemistry, and rock weathering observations indicate that parts of Larsemann Hills, East Antarctica have been subaerially exposed throughout much of the last glacial cycle, with the last glaciation occurring prior to 100 ka BP. Salt-enhanced subaerial weathering, coupled with a paucity of glacial erratics, m...

The article presents the results of a numerical simulation deformation-stress state in rock mass around salt cavern which is part CAES installation (Compressed Air Energy Storage). model based on parameters Huntorf power plant installation. influence temperature and salt-creep speed stability storage was determined basis three different stress criteria effort points at time intervals. analysis ...

Statement of the problem: The Phoenix Mission was the first to land in the polar regions on Mars. The mission revealed three surprising results: (1) The surface at the landing site had a very low concentration of large size rocks, (2) The unexpectedly sticky nature of the soil prevented it initially from falling through one of the instrument’s screens as planned, (3) Perchlorate salt was found ...

1. Stimulation in the rock barnacle Balanus balanoides by the sodium salts of the first seven normal aliphatic acids has been studied at several different concentrations for each salt. The pH was adjusted to that of sea water (8.1 +/-0.15) and all experimental conditions were held as constant as possible. Criterion of response was the per cent closure of valves at successive 2 minute intervals....

Intraterrestrial life has been found at depths of several thousand metres in deep sub-sea floor sediments and in the basement crust beneath the sediments. It has also been found at up to 2800-m depth in continental sedimentary rocks, 5300-m depth in igneous rock aquifers and in fluid inclusions in ancient salt deposits from salt mines. The biomass of these intraterrestrial organisms may be equa...

Oxygen, metals, silicon, and glass are raw materials that will be required for long-term habitation and production of structural materials and solar arrays on the Moon. A process sequence is proposed for refining these materials from lunar regolith, consisting of separating the required materials from lunar rock with fluorine. The fluorine is brought to the Moon in the form of potassium fluorid...

PURPOSE Retinal detachment disrupts the rod-bipolar synapse in the outer plexiform layer by retraction of rod axons. We showed that breakage is due to RhoA activation whereas inhibition of Rho kinase (ROCK), using Y27632, reduces synaptic damage. We test whether the ROCK inhibitor fasudil, used for other clinical applications, can prevent synaptic injury after detachment. METHODS Detachments ...

Salinized lake basins have distinctive sedimentary response characteristics, similar to marine shallow-water carbonate platforms. High-frequency cycles can also be used reveal more sedimentological information, such as relative lake-level fluctuations, lithofacies sequence combinations, and paleogeographic evolution. In this article, a comprehensive study on the stratigraphic shelf delineation ...
