    Notes: Communication, Craig (1989, 1995a, 1995b; Craig & Tracy, 1995) argues, is and should be a practical discipline: a field whose scholarly work would be helpful in improving the communicative practices it studies. Following explication of Craig's notions of practical theory and communication as a practical discipline, this paper analyzes the interactional trouble in one community's school board meetings. Drawing upon 3 theories relevant to this school board site - proposals about argumentative processes, rhetorical action, and moral conflict - we show how each theoretical lens leads to a different diagnosis of the community's ‘school board problem’. The second part of the paper inverts the analytic focus. Based on study of this school board's troubles, we critique the usefulness of the 3 theories. In the conclusion, we reflect about the often-invisible task of labeling the problem that a group is facing.

    Computerized electronic temperature control system for thermal efficiency during baking in food research (2001)

    Notes: A more sophisticated temperature control system than the capillary thermostat in conventional electric ovens is necessary for laboratory research on foods. The aim of the study was to develop a computerized temperature control system (CTCS) for conventional electric ovens and to determine whether the CTCS could effect comparable and consistent results in two ovens with regard to oven and product characteristics of baked products. No significant differences were found between the two ovens with regard to average oven temperature, texture and height of products. In most instances there were also no significant differences between the ovens with regard to instrumental colour measurement and moisture loss. The regression results also illustrated the effectiveness of the CTCS, i.e. that an increase in set oven temperature of 1°C has a significant effect on specific oven and product characteristics. The CTCS therefore significantly improved the reproducibility of quality characteristics of baked products. Thus, more consistent and repeatable results can be obtained to improve the reliability of consumer-driven food research.

    Properties of high κ gate dielectrics Gd2O3 and Y2O3 for Si (2001)

    Notes: We present the materials growth and properties of both epitaxial and amorphous films of Gd2O3 (κ=14) and Y2O3 (κ=18) as the alternative gate dielectrics for Si. The rare earth oxide films were prepared by ultrahigh vacuum vapor deposition from an oxide source. The use of vicinal Si (100) substrates is key to the growth of (110) oriented, single domain films in the Mn2O3 structure. Compared to SiO2 gate oxide, the crystalline Gd2O3 and Y2O3 oxide films show a reduction of electrical leakage at 1 V by four orders of magnitude over an equivalent oxide thickness range of 10–20 Å. The leakage of amorphous Y2O3 films is about six orders of magnitude better than SiO2 due to a smooth morphology and abrupt interface with Si. The absence of SiO2 segregation at the dielectric/Si interface is established from infrared absorption spectroscopy and scanning transmission electron microscopy. The amorphous Gd2O3 and Y2O3 films withstand the high temperature anneals to 850 °C and remain electrically and chemically intact. © 2001 American Institute of Physics.

    Atomic scale measurements of the interfacial electronic structure and chemistry of zirconium silicate gate dielectrics (2001)

    Notes: We have examined the interfaces in Zr-silicate gate dielectrics grown on Si substrates using electron energy loss spectroscopy. The Zr-silicate interface is found to be stable with the Si substrate and the polycrystalline silicon (poly-Si) electrode under annealing to 1050 °C. At this interface, a 0.35 nm wide Zr-free interface region is observed in the as-deposited film, and does not change on annealing. The Zr-free region is too thin to take on the bulk SiO2 electronic structure, and thus is unlikely to compromise the dielectric properties of the device. For films with an Al electrode, a 2 nm reaction layer forms at the Zr-silicate interface. © 2001 American Institute of Physics.

    Detection of luminescent single ultrasmall silicon nanoparticles using fluctuation correlation spectroscopy (2000)

    Notes: We dispersed electrochemical etched Si into a colloid of ultrasmall blue luminescent nanoparticles, observable with the naked eye, in room light. We use two-photon near-infrared femtosecond excitation at 780 nm to record the fluctuating time series of the luminescence, and determine the number density, brightness, and size of diffusing fluorescent particles. The luminescence efficiency of particles is high enough such that we are able to detect a single particle, in a focal volume, of 1 pcm3. The measurements yield a particle size of 1 nm, consistent with direct imaging by transmission electron microscopy. They also yield an excitation efficiency under two-photon excitation two to threefold larger than that of fluorescein. Detection of single particles paves the way for their use as labels in biosensing applications. © 2000 American Institute of Physics.

    Decreased Protein Phosphatase 2A Activity in Hippocampal Long-Term Potentiation (2000)

    Notes: Abstract: Using autophosphorylated Ca2+/calmodulin-dependent protein kinase II (CaM kinase II) as substrate, we now find that long-term potentian (LTP) induction and maintenance are also associated with a significant decrease in calyculin A-sensitive protein phosphatase (protein phosphatase 2A) activity, without changes in Mg2+-dependent protein phosphatase (protein phosphatase 2C) activity. This decrease in protein phosphatase 2A activity was prevented when LTP induction was inhibited by treatment with calmidazolium or D-2-amino-5-phosphonopentanoic acid. In addition, the application of high-frequency stimulation to 32P-labeled hippocampal slices resulted in increases in the phosphorylation of a 55-kDa protein immunoprecipitated with anti-phosphatase 2A antibodies. Use of a specific antibody revealed that the 55-kDa protein is the B′α subunit of protein phosphatase 2A. Following purification of brain protein phosphatase 2A, the B′α subunit was phosphorylated by CaM kinase II, an event that led to the reduction of protein phosphatase 2A activity. These results suggest that the decreased activity in protein phosphatase 2A following LTP induction contributes to the maintenance of constitutively active CaM kinase II and to the long-lasting increase in phosphorylation of synaptic components implicated in LTP.

    Notes: Six mullite samples, derived from heat-treated natural kaolinites with various iron content, were investigated and compared to synthetic monophasic mullite. They were analyzed by X-ray diffraction, diffuse reflectance spectroscopy, and electron paramagnetic resonance. To quantify mullite coloration, the CIE colorimetric system was used. In contrast to synthetic mullite, samples showed charge transfer bands involving O2− and Fe3+ ions as well as ferric crystal-field transitions due to Fe3+ ions in iron oxide nanoparticles. Absorption edges showed red shifts. The resulting yellowness, saturation of which increased with the content of iron oxide nanoparticles, is direct evidence for the coloring effect of Fe3+ ions.

    Behavior of Paramagnetic Iron during the Thermal Transformations of Kaolinite (2001)

    Notes: Kaolinites with various degrees of structural order and iron content were heated and subsequently analyzed via electron paramagnetic resonance. Iron was present in two different states in the heated materials, either as dilute structural Fe3+ ions or in concentrated Fe3+ phases. During metakaolinization, the environment of dilute Fe3+ ions changed, following modifications of the Al3+ coordination, and the Fe3+ concentration increased. With the breakdown of metakaolinite, the diffusion of Fe3+ ions induced their exsolution in superparamagnetic iron-rich domains (Fe3+ clusters in γ-Al2O3 and/or Fe3+ oxide nanophases), which produced a decrease in the dilute Fe3+ concentration. The subsequent breakdown of γ-Al2O3 and the formation of mullite made the dilute Fe3+ concentration increase again, because of the incorporation of Fe3+ ions in the mullite structure.
