Trees obtain water best when it is allowed to soak into the soil slowly to a depth of 12 inches . While only slight differences in translation could be found , the major discoveries came from Rachewiltz ’ s English version of the text because of the incredible depth of his background studies . This paper will begin by explaining the underlying technology , and then present in depth the case study of Jim , the building contractor mentioned above . After summarizing the progress to date , focus is on new developments with respect to experimental improvements such as ultra-low ion energy and glancing incidence , cluster ion sputtering , and improvements in theoretical modeling and quantification of nonlinearities with respect to the intensity scale and to the time scale of a depth profile , and the change of important quantification parameters such as electron escape depth in AES and XPS , mixing length and roughness during profiling , particularly when sputtering through interfaces .
