After a brief`warm-up' discussion of osmotic pressure of foams, the basic phenomena of foam rheology are reviewed, focusing on linear vis-coelastic spectra (elastic and loss moduli) with brief mention of nonlinear eeects. Theoretical models for some of these properties are then described, starting with Princen's model for the elastic modulus G 0 of an ordered foam in two dimensions. There is a ...

I develop a phenomenological approach to the description of the noise levels that the space-time foam of quantum gravity could induce in modern gravity-wave detectors. Various possibilities are considered, including white noise and random-walk noise. In particular, I find that the sensitivity level expected for the planned LIGO and VIRGO interferometers and for the next upgrade of the NAUTILUS ...

We propose that under certain conditions the universal open string tachyon can drive topological inflation in moduli stabilised frameworks. Namely, the presence of electric field in the world volume of the D-brane can slow down its decay leading to a phenomenological model of inflation. The conditions for inflation to take place are difficult to satisfy in the standard warped deformed conifold ...

The Jarlskog Invariant Jν−map of the neutrino mapping matrix is calculated based on a phenomenological model which relates the smallness of light lepton masses me and m1 (of ν1) with the smallness of T violation. For small T violating phase χl in the lepton sector, Jν−map is proportional to χl, but me and m1 are proportional to χ2l . This leads to Jν−map ∼= 1 6 √ me mμ +O ( √ memμ m2τ )

Based on a robust, phenomenological model for the growth of a system parameter, a relation is derived to test the evolution of such a parameter through several distinct stages. It is found that data defining the acknowledged major changes in the evolution of earth, the life on it, and cultural and technological growth, conform to this model. The nature of these altering events indicates that in...

The plastic flow of a foam results from bubble rearrangements. We study their occurrence in experiments where a foam is forced to flow in 2D: around an obstacle; through a narrow hole; or sheared between rotating disks. We describe their orientation and frequency using a topological matrix defined in the companion paper (F. Graner, B. Dollet, C. Raufaste, and P. Marmottant, this issue, 25 (2008...

We present an extension of the Tappin – Howard (TH) phenomenological model (Tappin and Howard, Space Sci. Rev. 147, 55, 2009) for coronal mass ejection reconstruction to use interplanetary scintillation g-map data. The necessary changes to the model are discussed. We then use the modified model to reconstruct two major interplanetary disturbances observed using the Cambridge 3.6 ha Array in Sep...
