Reaction of a polar gravel‐spit system to atmospheric warming and glacier retreat as reflected by morphology and internal sediment geometries (South Shetland Islands, Antarctica)

Earth Surface Processes and Landforms, 2019
Sedimentary architecture and morphogenetic evolution of a polar bay‐mouth gravel‐spit system are revealed based on topographic mapping, sedimentological data, radiocarbon dating and ground‐penetrating radar investigations. Data document variable rates of

SPIT Detection in Telephony over IP Using K-Means Algorithm

Procedia Computer Science, 2019
In few recently years, the number of unwanted messages and calls through IP telephony are increased rapidly. These undesirable messages and calls are booth annoy the receiver. However, the unsolicited calls are more annoying the callee, because he has to

Use of water as a tool by a beluga (Delphinapterus leucas)

International Journal of Comparative Psychology, 2023
Captive belugas ( Delphinapterus leucas ) often spit water as object play. One female beluga spit water at a ball to obtain it for play. We examined whether or not this behavior could be considered a tool-use behavior. When the ball was placed 10 cm from

The problem of land management traditions in The Curonian Spit

Journal of Architecture and Urbanism, 2007
The Curonian Spit was inhabited six thousand years ago. During this period its survival was menaced by natural forces. The 17th–18th centuries faced unreasonable deforestation of the Curonian Spit and opened its dunes to wind erosion. In the 18th century
