The Bolocam 1.1 mm Lockman Hole Galaxy Survey: SHARC II 350 micron Photometry and Implications for Spectral Models, Dust Temperatures, and Redshift Estimation

We present 350 micron photometry of all 17 galaxy candidates in the Lockman Hole detected in a 1.1 mm Bolocam survey. Several of the galaxies were previously detected at 850 microns, at 1.2 mm, in the infrared by Spitzer, and in the radio. Nine of the Bolocam galaxy candidates were detected at 350 microns and two new candidates were serendipitously detected at 350 microns (bringing the total in the literature detected in this way to three). Five of the galaxies have published spectroscopic redshifts, enabling investigation of the implied temperature ranges and a comparison of photometric redshift techniques. Lambda = 350 microns lies near the spectral energy distribution peak for z = 2.5 thermally emitting galaxies. Thus, luminosities can be measured without extrapolating to the peak from detection wavelengths of lambda > 850 microns. Characteristically, the galaxy luminosities lie in the range 1.0 - 1.2 x 10^13 L_solar, with dust temperatures in the range of 40 K to 70 K, depending on the choice of spectral index and wavelength of unit optical depth. The implied dust masses are 3 - 5 x 10^8 M_solar. We find that the far-infrared to radio relation for star-forming ULIRGs systematically overpredicts the radio luminosities and overestimates redshifts on the order of Delta z ~ 1, whereas redshifts based on either on submillimeter data alone or the 1.6 micron stellar bump and PAH features are more accurate.Comment: In Press (to appear in Astrophysical Journal, ApJ 20 May 2006 v643 1) 47 pages, 10 figures, 4 table

Increased material differentiation through multi-contrast x-ray imaging: a preliminary evaluation of potential applications to the detection of threat materials

Most material discrimination in security inspections is based on dual-energy x-ray imaging, which enables the determination of a material's effective atomic number (Zeff) as well as electron density and its consequent classification as organic or inorganic. Recently phase-based "dark-field" x-ray imaging approaches have emerged that are sensitive to complementary features of a material, namely its unresolved microstructure. It can therefore be speculated that their inclusion in the security-based imaging could enhance material discrimination, for example of materials with similar electron densities and Z eff but different microstructures. In this paper, we present a preliminary evaluation of the advantages that such a combination could bear. Utilising an energy-resolved detector for a phase-based dark-field technique provides dual-energy attenuation and dark-field images simultaneously. In addition, since we use a method based on attenuating x-ray masks to generate the dark-field images, a fifth (attenuation) image at a much higher photon energy is obtained by exploiting the x-rays transmitted through the highly absorbing mask septa. In a first test, a threat material is imaged against a non-threat one, and we show how their discrimination based on maximising their relative contrast through linear combinations of two and five imaging channels leads to an improvement in the latter case. We then present a second example to show how the method can be extended to discrimination against more than one non-threat material, obtaining similar results. Albeit admittedly preliminary, these results indicate that significant margins of improvement in material discrimination are available by including additional x-ray contrasts in the scanning process

Complete sequence and analysis of the ovine herpesvirus 2 genome

Ovine herpesvirus 2 (OvHV-2) is endemic in sheep populations worldwide and causes malignant catarrhal fever (MCF), a lymphoproliferative disease, in cattle, bison and deer. OvHV-2 has been placed in the gammaherpesvirus subfamily and is related closely to Alcelaphine herpesvirus 1 (AlHV-1). Here, the cloning, sequencing and analysis of the complete OvHV-2 genome derived from a lymphoblastoid cell line from an affected cow (BJ1035) are reported. The unique portion of the genome consists of 130 930 bp, with a mean G+C content of 52 mol%. The unique DNA is flanked by multiple copies of terminal repeat elements 4205 bp in length, with a mean G+C content of 72 mol%. Analysis revealed 73 open reading frames (ORFs), the majority (62) of which showed homology to other gammaherpesvirus genes. A further subset of nine ORFs is shared with only the related AlHV-1. Three ORFs are entirely unique to OvHV-2, including a spliced homologue of cellular interleukin-10 that retains the exon structure of the cellular gene. The sequence of OvHV-2 is a critical first step in the study of the pathogenesis and treatment of MCF

Towards more user-friendly education for speakers of Aboriginal English

The project reported on here set out, on a basis of cooperation between Aboriginal and non-Aboriginal investigators working in university, educational system and classroom contexts, to lead to understandings which would enable a more accessible ( userfriendly ) education to be provided for students in primary and secondary schools who are speakers of Aboriginal English. Specifically, in the context of schools of the Education Department of Western Australia, the project sought to: 1. extend knowledge and understanding of Aboriginal English and its areas of contrast with standard Australian English; 2. provide clarification in the following under-researched areas of Aboriginal English: a) semantic fields; b) functions of language use in relation to form; c) genres; d) particular registers; e) codes. 3. relate Aboriginal ways of approaching experience and knowledge to: a) curriculum; b) student outcome statements; c) pedagogical strategies to support two-way learning..

Renal ganglioneuromas in a pediatric patient: Case report and review of the literature

AbstractGanglioneuromas are rare benign tumors originating from the sympathetic nervous system and neural crest cells. A 4-year-old girl presented with numerous urinary tract infections. Ultrasound and computed tomography revealed a large mass within the right kidney. A right nephrectomy and sampling of surrounding lymph nodes were performed. Pathology confirmed that the mass was a mature ganglioneuroma. The patient remains disease-free, more than 2 years after surgery. We present this rare case of renal ganglioneuroma as well as a review of the literature

A Fluctuation Analysis of the Bolocam 1.1mm Lockman Hole Survey

We perform a fluctuation analysis of the 1.1mm Bolocam Lockman Hole Survey, which covers 324 square arcmin to a very uniform point source-filtered RMS noise level of 1.4 mJy/beam. The fluctuation analysis has the significant advantage of utilizing all of the available data. We constrain the number counts in the 1-10 mJy range, and derive significantly tighter constraints than in previous work: the power-law index is 2.7 (+0.18, -0.15), while the amplitude is equal to 1595 (+85,-238) sources per mJy per square degree, or N(>1 mJy) = 940 (+50,-140) sources/square degree (95% confidence). Our results agree extremely well with those derived from the extracted source number counts by Laurent et al (2005). Our derived normalization is about 2.5 times smaller than determined by MAMBO at 1.2mm by Greve et al (2004). However, the uncertainty in the normalization for both data sets is dominated by the systematic (i.e., absolute flux calibration) rather than statistical errors; within these uncertainties, our results are in agreement. We estimate that about 7% of the 1.1mm background has been resolved at 1 mJy.Comment: To appear in the Astrophysical Journal; 22 pages, 9 figure
