ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: In this article, we present pyroelectric investigations of electrically poled side-chain polymers containing mesogenic disazobenzene chromophores using a very simple setup. Heating above the glass temperature (about 104°C) usually eliminates the pyroelectric effect of the sample. However, in samples with an indium tin oxide/aluminum electrode design, a self-poling effect is observed. The pyroelectric coefficients of electrically poled samples reach values of up to 0.2 μC/(m2K). From this, we conclude that the strongly anisometric side chains can be reoriented, and that their degree of alignment is about 3%. © 2002 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Friction-stir welding of 6061 aluminum to copper produced a complex, intercalated microstructure which was also dominated by dynamic recrystallization. The friction-stir welding process is characterized by extreme plastic deformation in the solid state; there is no associated melting.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract Observations and measurements of the kinetics of coarsening and dissolution of large cuboidal niobium carbonitrides during solution treatments of a high nitrogen niobium microalloyed steel are reported. At temperatures between 1473 and 1573 K a competitive coarsening and dissolution process was established where the larger niobium carbonitrides grew at the expense of the smaller, or employing niobium and nitrogen which remained in solid solution. In this temperature range growth or dissolution rates and critical sizes could be determined from the analysis of the evolution of particle size distribution. At higher temperatures (1623–1723 K), only a dissolution process existed, where the dissolution rates as a function of particle size was found to increase with increasing temperature.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract An investigation was made of the grain-growth kinetics of the V–Nb microalloyed steel austenite phase at temperatures in the range 1173–1373 K, relevant for the understanding of the steel thermomechanical processing. The fine precipitation of vanadium- and niobium-rich particles plays an important role in helping the alloy to maintain a fine grain structure, which was characterized using optical microscopy, scanning electron microscopy and transmission electron microscopy. It was found that at temperatures where the fine precipitate particles are stable, the grain-growth process is slow and the mode of grain growth is normal. At higher temperatures where the precipitates are prone to dissolve, the abnormal grain-growth mode dominates. All the observations were comprised in a time–temperature map of the grain-growth modes. The map was built up by employing extensive line-intercept measurements of grain sizes at different temperatures and annealing times, followed by numerical calculations yielding curves of grain-growth rate as a function of grain size at different time intervals. The present experimental observations were found consistent with the results of calculations and predictions of the earlier theoretical work.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1573-2568Keywords: hepatic cirrhosis ; hyaluronan ; endotoxin ; cytokines ; ascitesSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Our objective was to investigate the relationship between endotoxin and hyaluronan synthesis and release in serum and ascitic fluid from cirrhotic patients. We studied hyaluronan, endotoxin, albumin, and creatinine levels in ascitic fluid and plasma and cytokine levels (IL-1β, IL-6, TGF-β) in ascitic fluid. TGF-β, IL-6, and IL-1β correlation analyses indicated a strong dependence of the production of these cytokines on endotoxin levels. Correlation analyses for TGF-β and IL-6 indicated a strong dependence of the production of hyaluronan on cytokine levels and, to a lesser extent, on IL-1β levels. Hyaluronan analysis indicated that a certain glycosaminoglycan level is required in ascites before its appearance in plasma. Our results disclosed elevated plasma hyaluronan concentrations. The simultaneous increased hyaluronan levels in ascitic fluid do not seem to be derived from the systemic circulation. In conclusion, the high hyaluronan-ascites/hyaluronan-plasma ratio suggests an intrinsic hyaluronan production from peritoneal cells induced by endotoxins.Type of Medium: Electronic ResourceURL:
