Seven piston cores were collected from the seafloor ~250 km south of Minamitorishima Island in the western North
Pacific Ocean during the cruise KR13-02 of R/V Kairei; in some portions of cores PC04 ...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
Dust driven mass loss from carbon stars as function of stellar parameters - II. Effects of grain size on wind properties
AGB and post-AGB – Stars: atmospheres – Stars: carbon – Stars: circumstellar matter – Stars: evolution – Stars: mass loss –2 Hydrodynamics – Radiative transfer
2011/9/30
In this paper we explore grain size effects on wind properties of carbon stars, using a generalized description of radiative cross sections valid for particles of arbitrary sizes. The purpose of the s...
HANDS-ON OCEANOGRAPHY——Sorting Out Sediment Grain Size and Plastic Pollution
Beach erosion beach plastic pollution sediment particle size the buoyancy material density sand
