137Cs contamination and its vertical distribution in the curonian spit soil
Journal of Environmental Engineering and Landscape Management, 2005 In 2003–2004 soil depthprofile sampling was carried out at Juodkrantein the Curonian Spit. The activity concentrations of anthropogenic radionuclide 137Cs in soil samples from the terrestrial and coastal environment of the Curonian Spit were determined ...

Boreas, EarlyView.The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

Truncated drumlins and their implication for past sea level reconstructions
Boreas, EarlyView.Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Entomologia Experimentalis et Applicata, EarlyView.MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Nonlinear dynamics of sand banks and sand waves [PDF]
, 2000 Sand banks and sand waves are two types of sand structures that are commonly observed on an off-shore sea bed. We describe the formation of these features using the equations of the fluid motion coupled with the mass conservation law for the sediment ...
