We have developed a 350μm radiometer to perform automated site testing in remote regions of Antarctica. In summer 2000–2001 the instrument operated at Concordia, a new station under construction at Dome C on the Antarctic Plateau. We present the results, and compare them with the atmospheric opacity measured at the South Pole in the same five-week period. During these five weeks, observing cond...

The Saturn-bound Cassini spammft is designed to rely, without preccdcn~ on the waste heat from its three radioisotope thcrrnocl~”c generators (RTGs) to warm the propulsion module subsystem, and the RTG end dome tcmpcmture is a key determining factor of the amount of waste heat delivered. A previously vatidatcd SINDA thermal model of the RTG was the sole guide to understanding its complex thcrma...

Elevation of the left dome of the diaphragm occurred in 43% of cases with left lobe amoebic liver abscesses. It was rarely seen in patients with an abscess in the right hepatic lobe. Elevation of the right dome of the diaphragm, which occurred in 36% of cases, is also compatible with a diagnosis of left lobe abscess. This radiological sign was present in 75% of cases with right lobe abscesses. ...

1Advanced Computing Research Centre, University of South Australia, Mawson Lakes, South Australia 5095 {Phillip Lock. [email protected]} Abstract. Game playing in immersive projection environments such as caves and domes is assumed to offer an enhanced experience but there is little quantitative research that measures this. This paper reports on a study of user performance statistics wh...

The unique atmospheric characteristics found at Dome C on the Antarctic plateau offer significant advantages for the operation of adaptive optics systems. An analysis is presented here comparing the performance of adaptive optics systems on telescopes located at Dome C with similar systems located at a mid-latitude site. The large coherence length, wide isoplanatic angle, and long coherence tim...

The architecture of bone trabeculae is based on the direction of stresses applied to the bone. The human talar dome receives compressive forces from the tibia and, to a much lesser extent, the fibula when standing, walking, and running, and transmits the force downward to the calcaneus through the talar body and anterior to the navicular via the talar head. As a result, the body of the talus ha...

A good astronomical site must fulfill several criteria including low atmospheric turbulence and low wind speeds. It is therefore important to have a detailed knowledge of the temperature and wind conditions of a location considered for future astronomical research. Antarctica has unique atmospheric conditions that have already been exploited at the South Pole station. Dome C, a site located on ...

[1] Ground surface tilts recorded proximal to a growing lava dome, and sustained through repeated dome collapses, provide unique geodetic constraints on the depth, size, and overpressures of the shallow magmatic system at Soufrière Hills Volcano. Tilt records identify a single pressure-source inflating with periods 3–30 h. Sustained tilt amplitude ratios for paired stations identify the pressur...

Salt domes, an important geological structure, are closely related to the formation of petroleum reservoirs. In many cases, no explicit strong reflector exists between a salt dome and neighboring geological structures. Therefore, interpreters commonly delineate the boundaries of salt domes by observing a change in texture content. To stimulate the visual interpretation process, we propose a nov...
