Aims. We analyse the large-scale structure out to 100 Mpc around a sample of 16 confirmed fossil systems using spectroscopic information from Sloan Digital Sky Survey Data Release 16. Methods. computed distance between our groups (FGs) and centres filaments nodes literature. also studied density bright galaxies, since this parameter is thought be good mass tracers, as well projected over-densit...

This study uses taphonomic, sedimentologic, and stratigraphic evidence from fossiliferous beds in Marblehead Quarry to review two hypotheses: 1) that the fossiliferous beds at Marblehead Quarry represent a series of in situ paleocommunities, and 2) whether fossiliferous concentrations in carbonate environments are primarily caused by periods of low net sedimentation. The fossiliferous beds of M...

The European energy sector has been undergoing significant changes since the beginning of the liberalization process in the UK in 1989. In 2003 major parts of the electricity sector in Europe have been liberalized and the remaining parts will follow during the next few years. This paper focuses on the promotion of renewable energy sources as an alternative to fossil fuels when aiming at a susta...
