A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or isolated by solid material. The basic character of the pore space affects and is affected by critical aspects of almost everything that occurs in the soil: the movement of water, air, and other fluids; the transport and the reaction of chemicals; and the residen...

In this paper, we studies the distribution of firm size by using a model based on Sato’s paper in 1970, and proved the static distribution of firm size satisfies Pareto distribution in its upper tail.

Introduction Conclusions References

in the present study, five log-normal models, normal model (n), and two four- parameter models namely gompertz (g) and fredlund (fr) were tested on 71 psd data from 10 soil textural classes. the jaky (j) and fr models had the smallest and largest r2 values for all of the soils, respectively. the results of comparing the n and simple log-normal (sl) models showed that the accuracy of the n model...

Functional genomics is as powerful as the diversity of phenotypes that are associated with the databases of DNA sequences and their expression patterns. A special bioinformatics challenge is to include detailed information in genomic databases about subtle phenoptypic differences that show continuous distribution in segregating populations. The objective of Real Time QTL (RTQ) is to present in ...

drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. in this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. a video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...
