The major phospholipids of Halorubrum lacusprofundi grown at 25 1C were archaeol phosphatidylglycerol, archaeol … phosphatidylglycerylsulphate and archaeol phosphatidylglycerylphosphate methyl ester.Glycolipids included a monoglycosyl archaeol and the sulphate ester of a diglycosyl archaeol.
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to … be exceptional for astronomy. The seeing (above ¡30m height), coherence time…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. The atmospheric conditions at Dome C … deliver a high sensitivity, high photometric precision, wide-field, high spatial resolution…
This paper describes an image analysis technique developed to identify icebergs depicted in synthetic aperture radar images of Antarctica, and to determine the outlines of these icebergs. The technique uses a pixel bonding process to delineate the edges of the icebergs.
As a result of selective pressures faced during lactation, vocal recognition may … play a crucial role in maintaining the phocid mother–pup bond during the period … of dependence. To investigate this possibility, we examined whether Weddell seal … (Leptonychotes weddellii)…
Vocal recognition may function as a critical factor in maintaining the phocid mother-pup bond during lactation. For vocal recognition to function, the caller must produce individually distinct calls that are recognised by their intended recipient.
The populations of two non-native Dipterans have been established at two Antarctic research stations … since at least 1998. Both belong to Sciaridae ("black … fungus midge"), and have been determined to the genus … Lycoriella. At Rothera Research Station, Antarctic … Peninsula…
Two series of mutant polypeptides of the type I, 37 residue winter flounder antifreeze protein have been synthesized and analyzed by nanoliter osmometry, the ice hemisphere test, measurement of ice growth hysteresis and circular dichroism spectroscopy.
