Ren et al. (2003) indicated that the distribution and transformation of plant dry matter is affected by shading, and some shading levels decreased rice yield.
Chl is directly involved in the absorption, transmission, distribution, and transformation of light energy in plants, facilitating the synthesis of organic material from photosynthetic products.
Otherwise, experiments with stable isotope tracers introduced into the environment have given invaluable information on the distribution and transformation behavior of mercury in the environment [ 5– 7].
These amendments can directly affect the chemistry of soil P by altering the amounts, distribution and transformations of P forms.
Phosphorus (P) availability is commonly assumed to limit productivity in many tropical soils, yet there is relatively little information on the phosphorus chemical forms, distribution, and transformations that P undergoes in Ethiopian soils.
Since the variable showed a largely skewed distribution and transformations did not correct the skewness, the answers were dichotomized: I drank alcohol in the past four weeks, 1 = yes, 0 = no.
Therefore in designing of the elements of the power grid (distribution stations and transformation stations) the technical protective norms are used in order to omit such mechanical effects [e.g. Poland – the Polish Norm is PN-EN 60865-1 2002(U ].
Utilizing these facilities and the support of national basic research grants, Chinese scientists have conducted extensive studies on factors such as background levels, distribution, transfer, and transformation patterns of dioxin in the environment.
For the analysis of performance data, the measures of error rates had pronounced heterogeneity of variance and skewed distributions and transformations were unsuccessful (cubic, square, identity, square root, log, 1/square root, inverse, 1/square, 1/cubic); analyses of these data were therefore performed using GEE models.
Reproductive traits (calving-first service interval, number of services per conception and total pregnancy rate) were analyzed with a generalized linear model (GENMOD procedure) with a Poisson distribution and log transformation (calving-first service interval) or a binomial distribution and logit transformation (pregnancy rate).
This causes a skew of the 'normal' distribution and a transformation of the data should be performed in these circumstances (Bland and Altman, 1996b, 1996c).
