From a case of acute endocarditis of the aortic and mitral valves with infarctions m the spleen and kidneys a micrococcus was twice isolated in pure culture from the blood during life and was demonstrated after death both microscopically and in pure culture in large numbers in the valvular vegetations, the infarctions and other parts. No other species of(More)
Selective catalytic reduction (SCR) technology increasingly is being applied for controlling emissions of nitrogen oxides (NOx) from coal-fired boilers. Some recent field and pilot studies suggest that the operation of SCR could affect the chemical form of mercury (Hg) in coal combustion flue gases. The speciation of Hg is an important factor influencing(More)
In the thirty-two unselected cases studied, cultures were taken from both the blood and the sputum, and in five of these more than one blood culture was taken. In one case the culture was taken from the blood only, and in this instance the pneumococcus was found. This case will be considered only with reference to the incidence of the pneumococci in blood(More)
A study was conducted to investigate the effect of selective catalytic reduction (SCR) catalyst on mercury (Hg) speciation in bituminous and subbituminous coal combustion flue gases. Three different Illinois Basin bituminous coals (from high to low sulfur [S] and chlorine [Cl]) and one Powder River Basin (PRB) subbituminous coal with very low S and very low(More)
A bench-scale reactor consisting of a natural gas burner and an electrically heated reactor housing a selective catalytic reduction (SCR) catalyst was constructed for studying elemental mercury (Hg(o)) oxidation under SCR conditions. A low sulfur Powder River Basin (PRB) subbituminous coal combustion fly ash was injected into the entrained-flow reactor(More)
1. In our examinations, only 38 per cent. of the infections of the respiratory tract below the glottis were pure, and this percentage was reached only by carefully following Kitasato's method of handling sputa. 2. Lobar pneumonia may produce sputum free from pneumococci, and may undoubtedly be caused by organisms other than thepneumococcus. 3. There is(More)
1. Streptococcus viridans is of extremely low virulence for white mice and rabbits. 2. The serum of rabbits, after a series of intravenous injections of dead or living Streptococcus viridans, is poor in complement fixative substance (fixateur of Besredka) for Streptococcus viridans. 3. Antigens prepared from several strains of Streptococcus viridans are(More)
The possibility of preparing a permanent staining solution from the formulas for Nocht's (I) stain was suggested by the constant use of Jenner's (2) stain for routine blood examinations and malarial staining during the summer and fall months of ~9ox. In malarial blood the pigmented bodies of tertian fever and the crescent bodies of mstivo-autumnal fever are(More)
The researches of Weichselbaum proved that the pneumococcus was .the etiological factor in the majority of the cases of lobar pneumonia which he investigated, and those cases in which the organism of Welch and Fraen~kel could not be isolated were therefore considered of minor import. In this latter class of cases Fried-1/inder's bacillus was usually thought(More)
