The application of direct-flame incineration to successfully eliminate a smoke-oil-mist and odor problem in the manufacture of rubber-base rug underlay, is presented. The investigation of various air pollution control processes leading to the development and adoption of the direct-flame incineration system, is covered. The rug-underlay curing process incorporating the direct-flame incineration system with primary heat recovery is described. Results and discussion of a source test to determine the effectiveness of direct-flame incineration in this application are included. 相似文献

A conference was held on October 30-31,1990 to examine discrepancies between the output of vehicle emission factor models (MOBILE and EMFAC), field and laboratory measurements of vehicle emissions, and observed ratios of pollutants in urban atmospheres dominated by vehicle emissions. There was a general consensus that significant discrepancies exist and that these discrepancies must be resolved. A number of research recommendations were made as to how models and model inputs could be improved, and what additional laboratory and field work should be conducted. 相似文献

Embryos of the large infaunal clam Laternula elliptica and the scallop Adamussium colbecki, from Antarctica, were cultured over an 18-month period. Their development rates were extremely slow, taking 240 and 177 h,
respectively, to reach the trochophore stage. This is ×4 to ×18 slower than related clams and scallops from temperate latitudes.
The relationship between temperature and development rate for bivalve molluscs shows the expected slowing with reduced temperature
(Q
10 in the range 2–4) for temperate and tropical species. However, the slowing at polar latitudes is much stronger than at warmer
waters, and all of the limited data for Antarctic species are well above the Arrhenius plot for the overall bivalve data,
and the Q
10 value for Antarctic to cool temperate species is 11.8, well outside the expected range for biological systems. Either the
relationships describing the effects of temperature on the kinetics of biological systems do not apply to Antarctic bivalve
molluscs, or some other factor that cannot be compensated for becomes important at low temperature. In the laboratory, L. elliptica embryos stayed viable in very sticky egg capsules for up to 18 months without hatching. However, even the disturbance of
removing eggs using a pipette ruptured some egg capsules allowing embryo release. Gametogenesis in Antarctic marine invertebrates
is almost universally slowed compared to temperate species, with nearly all cases documented requiring more than 1 year to
complete oogenesis. The only exception so far appears to be A. colbecki, which has a 1-year gametogenic cycle. The data here indicate that it has been unable to adapt embryonic development in a
similar way, and we are not aware of any exceptions to the markedly slowed development at low temperature rule. 相似文献
