The Spitzer Infrared Nearby Galaxies Survey (SINGS) is carrying out a comprehensive multiwavelength survey on a sample of 75 nearby galaxies. The 1–850 m spectral energy distributions (SEDs) are presented using broadband imaging data from Spitzer, 2MASS, ISO, IRAS, and SCUBA. The infrared colors derived from the globally integrated Spitzer data are generally consistent with the previous generat...
We report the discovery of a massive SCUBA core with evidence of inflow and outflow motions. This core is detected by SCUBA at both 450 and 850 μm. Barely resolved by the telescope beam at 450 μm, it has a size of 10, corresponding to 0.28 pc at a distance of 5.7 kpc. The dust temperature is estimated to be ≤ 29 K, the total mass is 820 M⊙ and the average density is 1.1×10 cm in a region with a...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
In spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is well described yet theoretical changes in decompression ratios have diminished the importance of fast tissue gas tensions as critical for bubble generation. The most serious signs and symptoms of D...
Despite the variety of marine organisms recorded from the Persian Gulf, acidians located along the Persian Gulf have not received much attention. We collected Ascidian samples from four sites along Larak Island (Persian Gulf) using Scuba diving and snorkeling at a depth that ranged from 5-15 m. Taxonomic identification was carried out by authoritative keys and texts. We found 4 species that be...
A group of schools striped eel catfish Plotosus lineatus (Thunberg, 1787) was photographed during scuba diving at depths 10 m and 17 on 11 July 2022 24 September from Kızkalesi Boğsak regions in the Mersin Bay Mediterranean coast Turkey. With present study, P. is extending its distribution to western coastal waters after first occurrence 2016 İskenderun Turkish Marine waters.
We present a deep, new 1200μm survey of the ELAIS N2 and Lockman Hole fields using the Max Planck Millimeter Bolometer array (MAMBO). The areas surveyed are 160 arcmin in ELAIS N2 and 197 arcmin in the Lockman Hole, covering the entire SCUBA ‘8 mJy Survey’. In total, 27 (44) sources have been detected at a significance ≥4.0σ (≥3.5σ). The primary goals of the survey were to investigate the relia...
To determine the aggregation effect of artificial reefs (ARs), we conducted surveys in 16 Taiwan by using scientific echo sounder, Simrad EY-60 (200 KHz), along with sighting scuba divers. Scuba diving was within reef structures (r ¼ 20 m), whereas acoustic were over a wider range 100 five repeating transects ARs. We compared results obtained from two methods among coastal waters to consistency...
Deep submillimetre(submm)-wave surveys made over the last three years using the SCUBA camera at the 15-m James Clerk Maxwell Telescope (JCMT) have revealed a new population of very luminous high-redshift galaxies. The properties of this population, and their contribution to the intensity of the extragalactic background radiation field are described briefly, especially in the context of the SCUB...
An individual case review of the diving-related deaths that were reported to have occurred in Australia in 2003 was conducted as part of the combined Project Stickybeak/DAN Asia-Pacific dive fatality reporting project. The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident are provided, as well as details ...
