Brane-world generalizations of the Einstein static universe [PDF]
, 2001 A static Friedmann brane in a 5-dimensional bulk (Randall-Sundrum type scenario) can have a very different relation between the density, pressure, curvature and cosmological constant than in the case of the general relativistic Einstein static universe ...

A maximum density rule for surfaces of quasicrystals [PDF]
, 2003 A rule due to Bravais of wide validity for crystals is that their surfaces correspond to the densest planes of atoms in the bulk of the material. Comparing a theoretical model of i-AlPdMn with experimental results, we find that this correspondence breaks

Modeling the Impact of Rhizosphere Bulk Density and Mucilage Gradients on Root Water Uptake
Frontiers in Agronomy, 2021 In models of water flow in soil and roots, differences in the soil hydraulic properties of the rhizosphere and the bulk soil are usually neglected. There is, however, strong experimental evidence that rhizosphere and bulk soil hydraulic properties differ

Density and $T_1$ of surface and bulk spins in diamond in high magnetic field gradients [PDF]
, 2018 We report on surface and bulk spin density measurements of diamond, using ultra-sensitive magnetic force microscopy with magnetic field gradients up to 0.5 T/$\mu$m.

BULK DENSITY AND COMPACT BULK DENSITY OF RICE BRAN FROM VARIOUS REGENCIES MIXED WITH RICE HUSK
Majalah Ilmiah PeternakanRice bran mixed with rice husk often occurs in the feed industry, as a result of scarcity of rice bran as animal feed. The aim of the study was to study the heap density and compaction density of rice bran obtained from various districts mixed with rice ...

Flux domes in superconducting films without edges
, 2006 Domelike magnetic-flux-density distributions previously have been observed experimentally and analyzed theoretically in superconducting films with edges, such as in strips and thin plates. Such flux domes have been explained as arising from a combination

Effects of Wetting-drying Cycles on Bulk Density and Saturated Hydraulic Conductivity of Soils
Guan'gai paishui xuebao, 2022 【Objective】 Changes in density and hydraulic conductivity of soil not only modulate subsurface hydrological processes but also affect root growth and root uptake of water and nutrients from soil.

(3200) Phaethon: Bulk density from Yarkovsky drift detection
, 2018 The recent close approach of the NEA (3200) Phaethon offered a rare opportunity to obtain high-quality observational data. We used the newly obtained optical light curves to improve the spin and shape model of Phaethon and to determine its surface ...

The Densities of Planets in Multiple Stellar Systems [PDF]
, 2017 We analyze the effect of companion stars on the bulk density of 29 planets orbiting 15 stars in the Kepler field. These stars have at least one stellar companion within 2", and the planets have measured masses and radii, allowing an estimate of their ...
