13. Temperature and pressure dependence of viscosity of quantum liquid 4He according to significant structure theory
Both solid-like and gas-like flow structures are considered in the calculation of viscosity of liquid 4He using the significant structure theory of liquids. The predominance of quantum mechanical zero-point motion over that arising from thermal excitation is taken into account for the solid-like motion of molecules. The viscosity of liquid 4He under its own

14. Beyond the diffusion limit: Water flow through the empty bacterial potassium channel
Water molecules are constrained to move with K+ ions through the narrow part of the Streptomyces lividans K+ channel because of the single-file nature of transport. In the presence of an osmotic gradient, a water molecule requires <10 ps to cross the purified protein reconstituted into planar bilayers. Rinsing K+ out of the channel, water may be 1,000 times

15. Initiation of clement surface conditions on the earliest Earth
In the beginning the surface of the Earth was extremely hot, because the Earth as we know it is the product of a collision between two planets, a collision that also created the Moon. Most of the heat within the very young Earth was lost quickly to space while the surface was still quite hot. As it cooled, the Earth's surface passed monotonically throug

16. Resistance to Water Transport in Shoots of Vitis vinifera L. 1: Relation to Growth at Low Water Potential
Apparent resistances to water transport in the liquid phase were determined from measurements of soil, root, basal shoot internode, shoot apex, and leaf water potentials and water flux in Vitis vinifera (cv White Riesling) during soil drying. Predawn water potential differences (ΔΨ) in the shoots accounted for 20% of the total ΔΨ between the soil and the
