The Relationship between the Con- Stitution of Brickmaking Clays
ABSTR&CT Seven brickmaking clays from various geological horizons have been studied by differential thermal and X-ray methods. The minerals detected included kaolinite, illite, montmorillonite, chlorite, swelling chlorite, calcite and quartz, and rough estimates were made of the quantities present. For the same clays, deformation-under-load was measured at four different heating rates, and stre...
متن کاملHowe Correspondence and Springer Correspondence
Consider real reductive group G, as defined in [Wal88]. Let Π be an irreducible admissible representation of G with the distribution character ΘΠ, [Har51]. Denote by uΠ the lowest term in the asymptotic expansion of ΘΠ, [BV80]. This is a finite linear combination of Fourier transforms of nilpotent coadjoint orbits, uΠ = ∑ O cOμ̂O. As shown by Rossmann, [Ros95], the closure of the union of the ni...

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. It appears that TCDD is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. The prominent hepatotoxic effect of TCDD is progressive centrilobular necrosis. Th...
متن کاملThe viability of using the Witwatersrand gold mine tailings for brickmaking
South Africa is a mineral-rich country with metals such as gold, copper, and platinum group metals being exploited to a significant extent in the country’s mining history. Mining generates large volumes of tailings, with consequent disposal and environmental problems. By far the most gold that has been mined in South Africa (98%) has come from the Witwatersrand goldfields (Messner, 1991). The g...
متن کاملOpen-Curve Shape Correspondence Without Endpoint Correspondence
Shape correspondence is the foundation for accurate statistical shape analysis; this is usually accomplished by identifying a set of sparsely sampled and well-corresponded landmark points across a population of shape instances. However, most available shape correspondence methods can only effectively deal with complete-shape correspondence, where a one-to-one mapping is assumed between any two ...
