INTRODUCTION An individual case review of diving-related deaths reported as occurring in Australia in 2006 was conducted as part of the Divers Alert Network Asia-Pacific (DAN AP) dive fatality reporting project. METHOD The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident and details from the post-morte...

Ejecta from core collapse supernovae contain a few solar masses of refractory elements and can therefore be the most important source of interstellar dust if these elements condense efficiently into solids. However, infrared observations of young supernova remnants, such as Cas A or Kepler, and observations of SN 1987A have detected only ∼ 10 M⊙ of hot dust in these objects. Recently, Dunne et ...

Drowning is the major cause of death in self-contained underwater breathing apparatus (SCUBA) diving. This study proposes an embedded system with a live and light-weight algorithm which detects the breathing of divers through the analysis of the intermediate pressure (IP) signal of the SCUBA regulator. A system composed mainly of two pressure sensors and a low-power microcontroller was designed...

Using the SCUBA instrument on the JCMT, we have made a submillimeter mosaic at 850μm of a subarea of the Spitzer First Look Survey (FLS). Our image covers the central 151 arcmin of the northern extragalactic Continuous Viewing Zone (CVZ) field of the FLS to a median 3σ depth of 9.7 mJy. The image contains ten 850μm sources detected at 3.5σ or higher significance, of which five are detected at ≥...

Deep SCUBA surveys have uncovered a large population of ultra-luminous galaxies at z > 1. These sources are often assumed to be starburst galaxies, but there is growing evidence that a substantial fraction host an AGN (i.e., an accreting super-massive black hole). We present here possibly the strongest evidence for this viewpoint to date: the combination of ultra-deep X-ray observations (the 2 ...

We present new near-infrared and optical spectroscopic observations which confirm the redshift of the z = 1.44 extremely red object ERO J164502+4626.4 (object # 10 of Hu & Ridgway 1994; formerly known as ‘HR 10’ or ‘[HR94] 10’) and a Hubble Space Telescope image which reveals a reflected-S–shaped morphology at (rest–frame) nearultraviolet wavelengths. The contrast between the rest–frame far-red...

We report IRAM millimeter interferometry of three z ∼2.4 to 3.4, SCUBA deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of confirmed, published redshifts of the faint submm-population and proving their high-z nature. In all three sources our measurements of the intrinsic gas and dynamical mass are large (10 10 to 10 11...

We present radio, optical and X-ray detected counterparts to the sub-mm sources found using SCUBA in the Hubble Deep Field North region (GOODS-N). A new counterpart identification statistic is developed to identify properties of galaxies detected at other wavelengths that can be used to aid counterpart identification. We discriminate between criteria that can use used to pre-select sub-mm brigh...

We present the first results of a submillimeter survey of distant clusters using the new Submillimeter CommonUser Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. We have mapped fields in two massive, concentrated clusters, A370 at and Cl 2244202 at , at wavelengths of 450 and 850 mm. The z 5 0.37 z 5 0.33 resulting continuum maps cover a total area of about 10 arcmin to 1 j noise ...

We have used SCUBA to survey an area of ≃ 50 arcmin2, detecting 19 sources down to a 3σ sensitivity limit of ∼3.5 mJy at 850μm. Monte-Carlo simulations have shown that the fluxes of sources in this and similar SCUBA surveys are biased upwards by the effects of source confusion and noise, leading to an overestimate by a factor of ∼1.4 in the fraction of the 850μm background that has been resolve...
