Radio Planetary Nebulae in the Large Magellanic Cloud
We present 21 new radio-continuum detections at catalogued planetary nebula
(PN) positions in the Large Magellanic Cloud (LMC) using all presently
available data from the Australia Telescope Online Archive at 3, 6, 13 and 20
cm. Additionally, 11 previously detected LMC radio PNe are re-examined with detections confirmed and reported here. An additional three PNe from our
previous surveys are also studied. The last of the 11 previous detections is
now classified as a compact \HII\ region which makes for a total sample of 31
radio PNe in the LMC. The radio-surface brightness to diameter (-D)
relation is parametrised as . With the
available 6~cm - data we construct - samples from 28 LMC
PNe and 9 Small Magellanic Cloud (SMC) radio detected PNe. The results of our
sampled PNe in the Magellanic Clouds (MCs) are comparable to previous
measurements of the Galactic PNe. We obtain for the MC PNe
compared to for the Galaxy. For a better insight into
sample completeness and evolutionary features we reconstruct the -
data probability density function (PDF). The PDF analysis implies that PNe are
not likely to follow linear evolutionary paths. To estimate the significance of
sensitivity selection effects we perform a Monte Carlo sensitivity simulation
on the - data. The results suggest that selection effects are
significant for values larger than and that a measured slope
of should correspond to a sensitivity-free value of .Comment: 19 pages, 9 figures, 6 table
Detecting filter-cake pathologies in solid-liquid filtration: Semi-tech scale demonstrations using electrical resistance tomography (ERT)
Chronic treatment with a stable obestatin analogue significantly alters plasma triglyceride levels but fails to influence food intake, fluid intake, body weight, or body composition in rats
Three-dimensional electrical impedance tomography applied to a metal-walled filtration test platform
CCRS proposal for evaluating LANDSAT-4 MSS and TM data
The measurement of registration errors in LANDSAT MSS data is discussed as well as the development of a revised algorithm for the radiometric calibration of TM data and the production of a geocoded TM image
Immunity to larval Brugia malayi in BALB/c mice: protective immunity and inhibition of larval development.
The objective of this study was to analyze the immune response of mice to the larval stages of Brugia malayi. Male BALB/c mice were inoculated with 3 doses of irradiated third-stage larvae (L-3) of B. malayi and were subsequently challenged with L-3 implanted ip within diffusion chambers. After 3 weeks, larvae were recovered to determine their viability, length, and stage of development. A significant reduction in parasite survival was observed in immunized mice. Furthermore, larvae recovered from immunized mice were significantly shorter than larvae recovered from control mice. All larvae recovered from immunized mice were L-3, whereas 96% of larvae recovered from controls were fourth-stage larvae (L-4). Sera collected from control and immunized mice were tested for the presence of antibodies reactive with L-3 and L-4 antigens using an indirect fluorescent antibody assay employing frozen larval cross-sections as antigen. Sera recovered after challenge of control mice reacted with internal, but not surface, antigens of L-3 and L-4. Alternatively, sera from immunized mice reacted with both internal and external antigens of both L-3 and L-4
Non-spherical optically trapped probes: Design, control, and applications
In this proceedings paper we show describe how a microtool can be assembled, and tracked in three dimensions such that its full rotational and translational coordinates, q, are recovered. This allows tracking of the motion of any arbitrary point, d, on the microtool's surface. When the micro-tool is held using multiple optical traps the motion of such a point investigates the inside of an ellipsoidal volume - we term this a 'thermal ellipsoid. We demonstrate how the shape of this thermal ellipsoid may be controlled by varying the relative trapping power of the optical traps, and adjusting the angle at which the micro-tool is held relative to the focal plane. Our experimental results follow the trends derived by Simpson and Hanna
Holistic corpus-based dialectology
This paper is concerned with sketching future directions for corpus-based dialectology. We advocate a holistic approach to the study of geographically conditioned linguistic variability, and we present a suitable methodology, 'corpusbased dialectometry', in exactly this spirit. Specifically, we argue that in order to live up to the potential of the corpus-based method, practitioners need to (i) abandon their exclusive focus on individual linguistic features in favor of the study of feature aggregates, (ii) draw on computationally advanced multivariate analysis techniques (such as multidimensional scaling, cluster analysis, and principal component analysis), and (iii) aid interpretation of empirical results by marshalling state-of-the-art data visualization techniques. To exemplify this line of analysis, we present a case study which explores joint frequency variability of 57 morphosyntax features in 34 dialects all over Great Britain
