The method of moments is used to develop short cut techniques that, for the three case studies considered, are virtually indistinguishable from the full models, yet are computationally far simpler. It is shown that when modelling a moderately complex flowsheet a four-fold reduction in dimensionality...

Quartz or crystalline silica is one of the most common minerals in the earth’s crust so that throughout the ages whenever mankind (and they were mostly, but not exclusively men) mined, quarried or worked the surface layers of the earth, they were exposed to quartz dust as the large crys...

Due to the membrane-damaging effect of DQ 12 silica and mixed dusts (enargite and porphyry rock dusts) an increase in acid phosphatase activity of macrophages could be observed at the end of the first month. At the same time non-fibrogenic or only mild fibrogenic dusts (bentonite, corundum...
Rheumatoid arthritis (RA) flare is related to increased joint damage, disability, and healthcare use. The impact of short-term air pollution exposure on RA disease activity is still a matter of debate. In this cross-sectional study, we investigated whether short-term exposure to particulate matte...
MG3—passive nanomaterials: For risk assessment, the general threshold limit value for dust is sufficient to ensure occupational safety upon long-term exposure since these nanomaterials do not elicit material-specific effects, but only cause effects under pulmonary overload conditions [104]. MG4—active...
the fcincrement successively decreased. It proves the negative influence of BP on the examined parameter. The short-term thermal loading caused an increase in mortar strength. The average increase in fcfor all the samples was 14.4%. Temperature loading leads to either a change in the calcium con...
