Republican leaders left behind in the various Capitols fumed, but Gov. Patrick J. Quinn of Illinois seemed to delight in the new arrivals, some of whom said Mr. Quinn, a Democrat, had telephoned them to offer his personal welcome.
After 180 days of hydration, the FTIR spectra of geopolymer mix specimens containing various silica fume contents are shown in Figure 7.
The distinct spalling performances of reactive powder concrete (RPC) specimens with various silica fume (SF) contents exposed to high temperatures were observed via high-resolution photography.
The ultrarapid-hardening polymer-modified mortar was prepared with various silica fume contents and polymer-binder ratios, and tested flexural strength, compressive strength, water absorption, carbonation depth and chloride ion penetration depth.
The most characteristic difference observed between the FTIR specta of geopolymer specimens made with various silica fume concerning bands attributed to the asymmetric stretching vibrations (T-O-Si) that increase in its intensity and broadness with a silica fume addition up to 7% while the pattern of 10% is subjected to the decrease in this band broadness.
Ca(OH 2/silica fume sorbents were prepared with various Ca(OH 2/silica fume weight ratios and slurrying times at 65°C and a water/solid ratio of 10/1.
It is possible that exposure to various dusts and fumes generated in railroad shops before 1959 in addition to diesel exposure influenced COPD mortality.
At a natural gas site, the toxic fumes from various parts of it — a compressor station and a storage tank, for example — are counted separately rather than cumulatively, so many overall gas well operations are subject to looser caps on their emissions.
Researchers are investigating several potential causes for the increase in asthma, including exposure to various allergens, traffic exhaust fumes, pesticides and certain plastics, as well as factors like obesity and diet that may play a role, said Dr. Rachel L. Miller, director of the asthma project at the Mailman School of Public Health at Columbia University.
Several recent epidemiologic studies describe occupational exposure ranges of approximately 0.01 5 mg/m Mn in fumes from various welding processes and materials (Korczynski 2000; Li et al. 2004; Sinczuk-Walczak et al. 2001).
