Small mammals were sampled at two waste burial sites (Sites 1 and 2) at Area G, TA-54, and a control site outside Area G (Site 3) to identify radionuclides that are present within surface and subsurface soils at waste burial sites, to compare the amount of radionuclide uptake by small mammals at waste burial sites to a control site, and to identify the primary mode of contamination to small mam...

Changes in both silicate weathering rates and organic carbon burial have been proposed as drivers of the transient “Mi-1” glaciation event at the Oligocene-Miocene transition (OMT; ~23 Ma). However, detailed geochemical proxy data are required to test these hypotheses. Here we present records of Li/Ca, Mg/Ca, Cd/Ca, U/Ca, δO, δC, and shell weight in planktonic foraminifera from marine sediments...

Falling of rigid body through air, water, and sediment is investigated experimentally and theoretically. Two experiments were conducted to drop rigid cylinders with the density ratio around 1.8 into shallow water (around 13 m deep) in the Monterey Bay (Exp-1) and into the Naval Postgraduate School’s swimming pool (Exp-2). During the experiments, we carefully observe cylinder track and burial de...

Ratcheting surfaces are a common motif in nature and appear in plant awns and grasses. They are known to proffer selective advantages for seed dispersion and burial. In two simple model experiments, we show that these anisotropically toothed surfaces naturally serve as motion rectifiers and generically move in a unidirectional manner, when subjected to temporally and spatially symmetric excitat...

In the physical processes of reclamation and urban renewal in Singapore, ground can be seen as a geomorphic entity that is endlessly shaped in accordance to a nationalistic vision. However, when the Chinese burial grounds in Singapore are repossessed for new usage, a contestation ensues between the contradicting values of land as a national resource and the landscape as a cultural entity. This ...

Double-O-tube shield tunneling technology has gained extensive attention due to saving space and the high cost-effectiveness of underground construction method. Estimating predicting DOT tunneling-induced soil displacements is essential prevent damage nearby aboveground structures in densely populated urban areas. This study develops a device for modeling based on transparent image processing t...

The study of the carbonate cements in the Permian-Triassic Dalan-Kangan formations resulted in the identification of five stages of calcite and dolomite cementation, which completely or partially occluded pores. Cement types appear to be early isopachous calcite (i; C1-non-luminescence), equant (ii; C2-dull CL), fairly coarse secondary dolomite rhombs (iii; C3-zoning red CL), coarse sparry calc...

The Shchukino burial ground is located 300 m west of the village Shchukino, Afanasyevsky district, Kirov region, on a small cape 14 high right bank river. Kama. site was discovered and studied by V.A. Kananin in 1977. A total 82 burials were studied. interest due to variety types rites. At site, made according rite cremation inhumation. There are grave pits without structural features there wit...
