SUBJECTS effusion

Identification of the molecular and cellular responses leading to the progressive development of asbestos-induced lung cancer, mesothelioma, pulmonary fibrosis, and pleural thickening and effusion has been the subject of extensive research within the past two decades. Published reviews of this work include those by Begin et al. (1992), Kamp and Weitzman (1997, 1999), Kamp et al. (1992), Luster and Simeonova (1998), Mossman and Churg (1998), Mossman et al. (1983, 1996), Rom et al. (1991), and Tanaka et al. (1998). 

Adverse effects. Molgramostim causes medullary bone pain, skin rashes, lethargy and myalgia in 10-20% of patients. It may also cause fever, the interpretation of which presents a clinical dilemma in neutropenic patients who are subject to sepsis. Pleural and pericardial effusions occur after high doses. 

A H (298.15 K) = 13.0 2 kcal mol" and = 158.5 2 kcal mol" are selected from reactions A, B, C and E (16) which are summarized below. The first three are isomolecular exchange reactions studied by mass spectrometry (1, i ) Reaction E is obtained from univariant Ti Og-TigOg by combining Knudsen effusion with the pressure ratio (TiO /TiO) 0.246 obtained from mass spectrometry (16). We use the same analysis (16) for (17, E), although the condensed phase may not be univariant. We presume that the smaller = 145.4 kcal mol" from reaction D is due to bias in the raass-spectrometric values (1 ) for the partial pressure of 0(g). Larger values of D from sublimation (, j ) and vaporization ( ) of TiO are subject to bias due to presence of species other than TiO in the vapor and to unknown liquid activities. Activities of TiO in TiO (cr) are very close to unity at x=l.0-1.1 and 1900 K according to emf data (20). 

To summarize it can be said that biodegradable polymers can be considered as a sensible complement to the traditional raw material source. However, effusive expectations should be curbed and the subject should be responsibly arranged in social context. 

The alpha-particle instrument is shown in Fig. 1. The gas, supplied from a conventional gas handling system, is irradiated in the ionization chamber. The radiation is supplied from an enclosed polonium alpha source of a few hundred millicuries. The irradiated gas bleeds through a leak out of the ion source and into the evacuated electrode chamber. There, the ions effusing from the leak are captured by the electric fields while the gas is pumped away. The ions are focused, accelerated, and then subjected to mass analysis and electron multiplier detection in a 90° sector field analyzer tube. 

The relative rates of effusion for gases obey Graham s law (see Problem 5.57). The isotope undergoes fission when bombarded with neutrons. However, its natural abundance is only 0.72 percent. To separate it from the more abundant isotope, uranium is first converted to UF, which is easily vaporized above room temperature. The mixture of gases is then subjected to mair stages of effusion. Calculate the separation factor, that is, the enrichment of relative to after one stage of effusion. 

To separate it from the more abundant isotope, uranium is first converted to UF5, which is easily vaporized above room temperarnre. The mixture of the and gases is then subjected to many stages of effusion. Calculate how much faster UFg effuses than UFe. 

Lundin and Yamamoto (1967) used the Knudsen effusion technique to determine the thermodynamic activities in the Gd-Y alloy system. The vapor pressures of both Gd and Y in the solid state are well below the measuring ability of this technique hence it was necessary to employ the molten state. Before analyses of the alloys, the vapor pressures of the pure components were measured. Vapors effused from nine liquid Gd-Y alloys at 1600°C were collected and subjected to X-ray spectrometer analysis. Activities of both components were determined from the ratio of the...
