    Cosmic Microwave Background Anisotropy. The anisotropy of the cosmic microwave background (CMB) consists of the small temperature fluctuations in the blackbody radiation left over from the Big Bang. The average temperature of this radiation is K as measured by .   Anisotropy observed in such MRI acquisitions is believed to be due primarily to the influence of cell membranes on the diffusing molecules (1,2). Due to the coarse resolution of typical MRI scans, an image voxel contains thousands of axons; hence, the observed anisotropy is a product of the cumulative effect of the membranes of thousands of by:

    black-body radiation Refers to the spectral shape of electromagnetic radiation within or emitted by an object in thermal equilibrium with its environment. The black-body spectrum is independent of the emitting material and depends only on the temperature of the emitting body. Clouds have a high albedo, causing much of the solar irradiation to be reflected back to space before it can ever reach the Earth's surface. Furthermore, longwave radiation which is radiated from the Earth's surface can also be scattered off of clouds and re-radiated to the Earth.

Owing to errors in scene identification and to the relationship between the spatial scales of cloud systems and the spatial resolution of the ERBE scanner, the anisotropy of the radiation fields determined from ERBE observations was suspected of exhibiting a field of view size : Qian Ye.

This effect is observed in the case of zHg ) zT1* 7 > 2TI. Under the influence of magnetic resonance in the ground state of z Hg the orientation has a time dependent modulation. This effect is observed as the modulation of the y-ray by: The growth behaviour of interstitial-type dislocation loops in Au as observed in a high-voltage electron microscope is used to determine the anisotropy and temperature dependence of the threshold energy for atom displacement, E d.

The motion of a large (≳ Mpc radius) volume of local matter with respect to the frame in which the thermal cosmic background radiation (CBR) appears isotropic is shown to produce a contribution to anisotropy in the arrival directions of the highest energy (> eV) cosmic rays.
