ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Recent developments in seismological geodesy
With the advanced development of the modern geodetic techniques, the geodetic observations have been proved to be more powerful to uncover the geophysical phenomena, especially the seismic one, than that in the past time.

The three Swedish kings of geodesy – Speech at the NKG General Assembly dinner in 2022
During the 1950s–1970s, there were three geodesy professors in Sweden. Before and after that period the only such position was at KTH in Stockholm. One in the triple proposed the creation of the Nordic Geodetic Commission, which was realized in 1953 and ...

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates
Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium

Numerical solutions for lunar orbits [PDF]
Starting from a variational formulation based on Hamilton’s Principle, the paper exploits the finite element technique in the time domain in order to solve orbital dynamic problems characterised by constrained boundary value rather than initial value ...
