Para conocer el estado de salud los arrecifes se han creado protocolos que permiten evaluar indicadores ecológicos sobre grupos focales organismos habitan en ellos. En este estudio propone una escala específica, clasificación y puntaje condición salud, para seis (densidad, número especies por transecto, cobertura, muerte antigua, reciente densidad reclutas) la comunidad corales del Parque Nacio...

We present 850$\mu$m observations of a sample 8 nearby spiral galaxies, made using the SCUBA-2 camera on James Clerk Maxwell Telescope (JCMT) as part JCMT Nearby Galaxies Legacy Survey (NGLS). corrected our data for presence $^{12}$CO $J=3\to 2$ line in bandwidth NGLS HARP data, finding typical contribution $\sim 20$%. measured dust column densities, temperatures and opacity indices by fitting ...

INTRODUCTION An individual case review of diving-related deaths reported as occurring in Australia in 2007 was conducted as part of the on-going Divers Alert Network (DAN) Asia-Pacific 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...

The sub-mm waveband has opened up for cosmology, and through this window we can hope to glimpse some answers to a number of related puzzles: What are the brightest sub-mm galaxies? What sorts of galaxies make up the Far-IR Background (FIB)? When did the Universe form the bulk of its stars? How important is dust obscuration for obtaining a full star-formation census? SCUBA has been instrumental ...

The effect of litter on the abundance and community structure of soft-bottom epibenthic megafauna was investigated in three coves of the Saronikos Gulf (Aegean Sea). At each site, two surfaces were defined on the sea-bottom. One of the surfaces was uniformly littered with debris (16 items per 100 m(2)), while the other remained 'clean' and acted as control. Benthic megafauna was censused with S...

We present the complete submillimeter data for the Canada-UK Deep Submillimeter Survey (CUDSS) 3 h field. The observations were taken with the Submillimeter Common-User Bolome-ter Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT) on Mauna Kea. The 3 h field is one of two main fields in our survey and covers 60 square arc-minutes to a 3σ depth of ∼ 3 mJy. In this field we have detected 2...

We present 850 $\mu$m dust polarization observations of the massive DR21 filament from B-fields In STar-forming Region Observations (BISTRO) survey, using POL-2 polarimeter and SCUBA-2 camera on James Clerk Maxwell Telescope. detect ordered magnetic fields perpendicular to parsec-scale ridge main filament. sub-filaments, are mainly parallel filamentary structures smoothly connect compare Planck...

Epidemiological and experimental studies indicate that environmental and dietary factors are probably important determinants of colorectal cancer (CRC). Among dietary factors alcohol intake has been shown to be associated with an increased risk of CRC (1). A large number of epidemiologic studies have examined the possible association of beer and ethanol ingestion on CRC risk. As a result, some ...

Using the IRAM interferometer we have detected J=4→3 and 5→4 CO line emission toward the radio quiet quasar PSS 2322+1944. At a redshift of zCO = 4.1199 this is the fourth and strongest detection of CO at z > 4. The velocity-integrated CO J=4→3 and J=5→4 line fluxes are 4.21± 0.40 and 3.74± 0.56 Jy kms−1, and the linewidth is ≈ 300 kms−1. The CO J=10→9 was searched for but not detected with an ...
