In a review of global patterns of root decomposition, Silver and Miya (2001) found that the substrate quality parameters, root Ca concentration and C/N ratio, could explain the greatest proportion of the variance in decay rates across a range of sites and species (r = 0.89, ft = 17) ...

This means that, along with the root decomposition of the algebra G = T0V " 0V (over C), there exists another natural decomposition (over R) ... 

We have investigated the root decomposition of the algebra sl(n, C). Therefore, we can now easily write in an explicit form the canonical embedding of the compact form Gc into the algebra sl(n, C). 

Furthermore, one may need to employ data transformation. For example, sometimes it might be a good idea to use the logarithms of variables instead of the variables themselves. Alternatively, one may take the square roots, or, in contrast, raise variables to the nth power. However, genuine data transformation techniques involve far more sophisticated algorithms. As examples, we shall later consider Fast Fourier Transform (FFT), Wavelet Transform and Singular Value Decomposition (SVD). 

Humus The dark organic material in soils, produced by the decomposition of soils. The matter that remains after the bulk of detritus has beenconsumed (leaves, roots). Humus mixes with top layers of soil (rock particles), supplies some of the nutrients needed by plants -increases acidity of soil inorganic nutrients more soluble under acidic conditions, become more available, EX. wheat grows best at pH 5.5-7.0. Humus modifies soil texture, creates loose, crumbly texture, that allows water to soak in and nutrients retained permits air to be incorporated into soil. 

Aconitum lycoctonum. From the roots of this species Hiibschmann isolated the amorphous alkaloids acolyctine and lycoctonine. Dragen-dorff and Spohn showed that Hiibschmann s alkaloids were probably decomposition products of lycaconitine, C2,H3403N2. 2H2O, which they isolated along with myoctonine, 27 30 8 2 - 5H2O. These results liave been considerably extended by Schulze and Bierling, and more recently by Marion and Manske, for lycoctonine.

The early literature on naturally occurring plant growth inhibitors and the influence one plant might exert on another by chemical means (allelopathy) is considered comprehensively in various reviews (12, 15, 36, 37, 48, 49, 61, 67, 94, 121, 162). Reviews of studies concerned with the influence of plant exudates on root-infecting fungi (130) and the effects of phytotoxins which arise as decomposition products (113) have appeared recently. Because of the excellent coverage of the topics by others, no attempt is made here to review the early literature exhaustively. Instead, consideration is restricted essentially to specific compounds and to some of the more recent literature.

The amount of hydrogen chloride captured as sodium chloride was proportional to square root of time and sodium diffusion coefficients in glass cullets calculated were 2.9 - 3.9xl0 m /s at 823K. Also, chlorine-firee char can be produced by steam decomposition, even though particle size issue remains.
