A Halo Model with Environment Dependence: Theoretical Considerations [PDF]

, 2011
We present a modification of the standard halo model with the goal of providing an improved description of galaxy clustering. Recent surveys, like the Sloan Digital Sky Survey (SDSS) and the Anglo-Australian Two-degree survey (2dF), have shown that there

Examination of a Theoretical Model for Drainage of Foams Prepared from Licorice Root Extract Solution

Colloids and Interfaces, 2023
The root of the licorice plant (Glycyrrhiza glabra) is rich in natural surfactants, called saponins. The beneficial properties of this plant have led to different applications, including its use as a foaming agent.

Theoretical solar models [PDF]

Symposium - International Astronomical Union, 1997
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling.
