At the root of theoretical soil mechanics, outlined in the previous chapter, is the assumption that soils act as a mechanical continuum the reaction of which to stress is modified by an idealized particle structure and by the presence of pore water. This may be an acceptable approximation with respect to granular and cohesionless soils. However, in the

In the report "Transfection of v-ras(H) DNA into MCF-7 human breast cancer cells bypasses dependence on estrogen for tumorigenicity" by A. Kasid et al. (10 May, p. 725), a line connecting two sentences was inadvertently omitted from the text. On p. 726, column 1, line 9, the sentence beginning "Densitometric scans of the blots " should have continued ...

Clay and Clay Mineral Definition
2017Any science, scientific field, or scientific domain requires a well-established and defined object of study as well as appropriate methodologies to develop knowledge about that object. However, over time the definition or concept of the object of study can undergo modifications and adaptations due to scientific advances, both in theoretical and ...

Chapter 1 General Introduction: Clays, Clay Minerals, and Clay Science
2006Publisher Summary This chapter attracts the attention of clay scientists in academe and industry as well as in politics (as research needs funding), and focuses on the importance of clay science to society and the quality of life. The economic benefits seem evident because clays are abundant, widespread, and inexpensive compared with other raw ...

Industrial clays: kaolin (china clay), ball clay and bentonite
1995Kaolin (or china clay), ball clay and bentonite are the dominant ‘industrial clays’, and are mined for a wide variety of uses (Table 3.1), which exploit the special properties of each of the three clay types: Kaolin (china clay) — is chemically inert and can be prepared as a white powder specified (in part) according to its whiteness and ...
