    Notes: Abstract We have examined the distribution of olfactory marker protein (OMP), protein gene product 9.5 (PGP 9.5) and calcium-binding protein D-28k (CaBP) in the olfactory epithelium of mid- to late fetal and newborn humans using immunocytochemistry. Olfactory chemoreceptor neurons (ORNs) in a 24-week-old female fetus, a 31-week-old male fetus and a newborn male were examined. OMP-like immunoreactivity (-LI) and PGP 9.5-LI were distributed throughout ORNs at all ages. CaBP-like immunoreactivity, however, was found only in clustered or isolated fetal ORNs; in the newborn, CaBP-LI was seen only in isolated ORNs sparsely distributed throughout the OE. These findings demonstrate that human ORNs express OMP-LI nearly 4 weeks earlier in development than previously reported. PGP 9.5-LI is coincidentally abundant within these cells, suggesting it may have an important role in mature ORNs. Because the number of ORNs expressing CaBP-LI decreases during perinatal development, CaBP may be important in intracellular calcium regulation during ORN growth and maturation in the developing OE.

    Notes: Abstract  The high aspect ratio, deep x-ray lithography and electrodeposition process [Becker et al. (1986)] can be expensive unless throughput is high enough. The use of a very high energy synchrotron has allowed the cost of exposure to be significantly reduced through simultaneous exposure of stacked photoresist [Guckel et al (1994)]. Synchrotron radiation at high photon energies has resulted the use of a large area x-ray mask. Both stacked exposures and a large area x-ray masks have significantly increased the throughput of the deep x-ray lithography and electrodeposition process.

    Film quality in relation to deposition conditions of a-SI:H films deposited by the "hot wire'' method using highly diluted silane (1996)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 79 (1996), S. 7278-7292 
    Details
    ISSN: 1089-7550

    Notes: The deposition parameter space has been extensively explored using the hot wire technique with 1% SiH4 in He as a source gas. To achieve reasonable deposition rates despite the high dilution, the filament was positioned at 1–2 cm from the substrate. This short distance introduced a large nonuniformity across the substrate in deposition rate as well as in film properties. These spatial variations were used to analyze which factors in the deposition determine film quality. Radiation from the filament as well as deposition rate cannot explain the large variation in film properties, leaving gas-phase reactions of Si and H from the hot filament as the primary cause. It is clear that radicals evaporated from the filament must undergo gas-phase reactions with SiH4 before deposition in order to produce high-quality material. Thus, conditions such as increasing the chamber pressure or going to a heavier carrier gas increase the fraction of radicals that can react before reaching the substrate and, therefore, improve the film quality. However, such conditions also enhance multiple radical reactions before such radicals reach the substrate and this can have a negative effect on film quality: this is attributed to gas-phase nucleation with incorporation of conglomerates. The gas-phase chemistry is quite different from that of plasma-enhanced decomposition in that no disilane or trisilane is formed in significant quantities. This, and the dependence on pressure, indicates that the pathway for formation of these heavier particles is radical–radical reactions. © 1996 American Institute of Physics.

    Syndeformational fluid trapping in quartz: determining the pressure-temperature conditions of deformation from fluid inclusions and the formation of pure CO2 fluid inclusions during grain-boundary migration (1995)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Abstract Observations and microthermometric data on fluid inclusions from a terrane that underwent deformation following peak metamorphic conditions show that grain-boundary migration recrystallization favours the entrapment of carbonic inclusions whereas microfracturing during brittle deformation favours the infiltration and eventual entrapment of aqueous fluids. Our results imply that pure CO2 fluid inclusions in metamorphic rocks are likely to be the residue of deformation-recrystallization process rather than representing a primary metamorphic fluid.Where the temperature of deformation can be deduced by other means, the densities of fluid inclusions trapped during recrystallization, which we call recrystallization-primary fluid inclusions, can be used to constrain the ambient pressure during deformation. Using these constraints, the data imply that the post-metamorphic Hercynian exhumation in Sardinia brought rocks at 300° C to within 3km of the surface. This conclusion is similar to that described for the rapidly uplifted Southern Alps in New Zealand.

    The Need for Consideration of Fire Behavior and Effects in Prescribed Burning (1995)

    Notes: Prescribed burns are increasingly being used in ecological restoration and vegetation management. Despite the accumulation of scientific information on fire behavior and fire effects, however, in many cases fires are prescribed without consideration of such information and often simply because of evidence of past fires. Rather than basing fire management plans on ideas of the historical “natural” occurrence of fire, we present the case for fire management being based on the fire effects desired. Effective fire management and development of proper fire prescriptions require an understanding of fire processes and heat transfer that explain fire behavior characteristics, as well as an understanding of how fire behavior is coupled to specific fire effects. We provide a basic introduction to these concepts and processes, which will help in understanding the importance of having a more technical understanding of fire. The discussion includes the processes of heat transfer and the relative role of various fuel variables in these processes, as well as the concepts of fire intensity, rate of spread, fuel consumption, duff consumption, fire frequency, and the ecological effects associated with variation in these characteristics of fire behavior.

    Notes: This paper describes Rossby waves propagating along a channel with a discontinuity in potential vorticity. A finite-amplitude, long-wave equation giving the displacement of the material interface separating two constant vorticity regions is derived and solved for both steady and unsteady finite-amplitude waves. Finite-amplitude Rossby waves that propagate in the opposite direction to infinitesimal waves are identified, and the mechanism for these waves is elucidated. The full parameter space of possible flows is described quantitatively. The weakly nonlinear limit of this finite-amplitude equation is also presented, including the novel case of kink solitons in an equation with only quadratic nonlinearity. © 1999 American Institute of Physics.

    Notes: The undulator based beamline X13A at the National Synchrotron Light Source has been commissioned recently. The X13 undulator has an 8 cm period, and its first harmonic is in the energy range of 200–700 eV at the nominal ring energy of 2.5 GeV. The beamline uses horizontally deflecting optics. It consists of a SiC plane mirror, a water cooled entrance slit, a spherical grating, and two fixed exit slits. A flux of more than 1012 photons/s at 450 eV has been measured at X13A with an aluminum-oxide photodiode with a 200 μm entrance slit, a 500 μm exit slit, and a ring current of 242 mA. A VF3 absorption spectrum recorded at X13A shows the monochromator resolving power is at least 1000 at ∼500 eV with 30 μm entrance and exit slits, in agreement with calculations. The X13A beamline will be used for x-ray coherence studies, spectroscopy, and multilayer reflectivity measurements as well as for x-ray instrumentation diagnostics. © 1995 American Institute of Physics.

    X-ray resonant magnetic scattering ellipsometer : The 9th National conference on synchrotron radiation instrumentation (1996)

    Notes: It is very difficult to characterize the polarization of a synchrotron radiation source in the soft and/or intermediate x-ray energy region particularly from 1 to 2 keV. Conventional multilayer mirror or single-crystal polarimeters do not work over this energy region because their throughput (the reflectivities combined with the phase shift) becomes insignificant. In this paper, we present a new ellipsometer scheme that is able to fully characterize the polarization of synchrotron radiation sources in this energy region. It is based on the dichroic x-ray resonant ferromagnetic scattering that yields information on both the polarization of the x-ray and the material (element specific) dielectric-constant tensor [C.-C. Kao et al., Phys. Rev. B 50, 9599 (1994)] due to the interband ferromagnetic Kerr effect [B.R. Cooper, Phys. Rev. A 139, 1504 (1965)]. © 1996 American Institute of Physics.

    Notes: Magnetotransport measurements are reported for In0.53Ga0.47As layers grown by molecular beam epitaxy (MBE) at different substrate temperatures (Ts) and either δ- or slab-doped with Si. Multiple subband densities deduced from the Fourier analysis of 1.2 K Shubnikov–de Haas measurements are compared with those derived from self-consistent calculations which include nonparabolicity and the doping profile width wSi as a fitting parameter. Significant spreading of the Si donors away from the doping plane is deduced for deposition at Ts≈520 °C, while no measurable migration is inferred for Ts≤470 °C, leading to near-ideal δ-doping behavior. Contrary to previous results [McElhinney et al., J. Cryst. Growth 150, 266 (1995)], no evidence for amphoteric behavior has been found for Si areal densities up to 4×1012 cm−2. © 1996 American Institute of Physics.
