  The traditional method required 13,445 individual evaluations while the new approach required only 2,000 estimates. Results from the new approach were compared with those from the traditional method for a sample of 210 occupation/industry combinations,salt grinding machine. The kappa statistic for the agreement of the methods was found to be 0.82 with an exact agreement by level for 89 percent of the occupation/industry combinations. The markedly smaller amount of time and the high correlation with the more time-intensive procedure suggest that this new procedure may be an efficient approach to exposure assessment in case-control studies.
  
  An air gun repeatedly shot in a water-filled hole every 6 or 10 s was used to measure the in situ seismic velocity over a distance of 200 m in a granite quarry. We found a peak-to-peak half-percent variation of velocity,clinker grinding unit, which correlates well with the variation in tidal stress. The inferred high stress sensitivity of velocity change (0.2 bar−1) may be attributed to the presence of extremely thin cracks (aspect ratio 10−5) by which the rock mass near the surface is broken into blocks. Such cracks should close at a depth of about 15 m. When the present results for detecting the tidal effect on velocity are extrapolated for waves penetrating to depths of a few kilometers, the velocity must be measured with a precision of better than one part in 105.
  
  The present invention relates to the production of building blocks and in particular it relates to building blocks and tiles which simulate slabs quarried from natural granite.Large quantities of pulverized granite waste is available wherever granite has been quarried and this waste is found in practice to include particles of a considerable range of sizes.
