Lenticular Hills of Glacial Drift

Comparison of Vegetation of Kansas-Nebraska Drift-Loess Hills and Loess Plains

Were the Larsemann Hills ice-free through the Last Glacial Maximum?

Lake sediments in the Larsemann Hills contain a great diversity ofbiological and physical markers from which past environments can be inferred. In order to determine the timing of environmental changes it is essential to have accurate dating of sediments. We used radiometric (*loPb and I3'Cs), radiocarbon (AMS "C) and uranium series (2'*U) methods to date cores from eleven lakes. These were sam...

High Maneuverability Lenticular Airship

This paper presents and describes a new lenticular shaped airship that allows 3D omnidirectional movements. The airship is intended to be part of a cooperative aerial system based in the synergy between an airship and a group of micro-quad rotors capable of long time missions as environmental, biodiversity monitoring, WiSAR missions, road monitoring, detection of forest fires, etc. The emphasis...

Lenticular abnormalities in children.

PURPOSE To study the lenticular problems in children presenting at an apex institute. METHODS Retrospective analysis of records (< 14 years) of new lens clinic cases was done. RESULTS Of 1,047 children, 687 were males. Mean age at presentation was 6.35 ± 4.13 years. Developmental cataract was seen in 45.6% and posttraumatic cataract in 29.7% of patients. Other abnormalities were cataract wi...

Airborne laser swath mapping of the Denton Hills, Transantarctic Mountains, Antarctica: Applications for structural and glacial geomorphic mapping

High-resolution digital elevation data acquired by airborne laser scanning (ALS) for the Denton Hills, along the coastal foothills of the Royal Society Range, Transantarctic Mountains, are examined for applications to bedrock and glacial geomorphic mapping. Digital elevation models (DEMs), displayed as shaded-relief images and slope maps, portray geomorphic landscape features in unprecedented d...
