“…Finally, the presence of lithic refits and the fresh edges of the lithic tools does not support the presence of even moderate water flows at the time of burial. As indirect evidence, we may add that the largest distance between refits is around 2 m, which seems to be the usual dispersal of elements in a knapping sequence (Cziesla, ).…”

Evidence of late Early Pleistocene elephant butchery activity has been excavated in the Pit 1 locality at Barranc de la Boella (Catalonia, Spain). The fossil assemblage mainly comprises the remains of one prime adult individual of Mammuthus meridionalis, together with 125 lithic artefacts, among which several refitting groups of chert have been identified. The lithic assemblage from the Pit 1 locality is composed of cobbles, cores, simple and retouched flakes, together with a large, well-fashioned pick of hard-wearing schist. Spatial, zooarchaeological, taphonomic, technical and use-wear analyses confirm that the occupation was devoted to butchery of the mammoth carcass. The activity zone is in a fluvio-deltaic area that incises the terrace Tþ60 of the lower Francolí river basin, 50 m a.s.l. Palaeomagnetic and cosmogenic analyses, as well as microfaunal (Mimomys savini, Victoriamys chalinei) and macrofaunal biostratigraphy (Mammuthus meridionalis), support the timing of the occupation to the late Matuyama chron. These various lines of evidence point to Barranc de la Boella being the oldest Early Acheulean butchering site in Europe. Ongoing excavations at several localities at Barranc de la Boella are yielding new data on the palaeoenvironmental, geochronological and technological framework of these occupations. Finally, the evidence is integrated into current understanding of the subsistence strategies practised by Early Pleistocene hominins.

“…As a widespread and typical implement, these artefacts can be seen as a part of the common tool kit used by Early Mesolithic hunter-gatherers. Even though such points had a wide distribution in the North German Lowland, Southern Scandinavia and the Netherlands, regional differences in type and technology provide a useful and suitable topic for over-regional studies of contact, exchange and traditions (Cziesla 1999;Clark 1936;Gramsch 1973;1993;/2010Verhart 1988).…”

“…He differentiated, among others, the ones from Duvensee as type 2, Pritzerbe as type 7 and a third group with oblique grooves as Kunda points (type 4). In the latest publication of bone points from Brandenburg (Cziesla 1999) and northwestern Poland (Galiński 2013) the finely notched points of type 2 were categorised as Duvensee points. During the 1950s to 1990s large numbers of Duvensee points were dredged up from the rivers in Brandenburg and excavated at Mesolithic settlements like Friesack and Hohen Viecheln in Northern Germany (Cziesla 1999;Gramsch 2009Gramsch /2010.…”

This paper presents an evaluation of the environmental performance of an advanced zero emission plant (AZEP) including CO2 capture. The evaluation is conducted with the aid of an advanced exergoenvironmentai analysis. The results are compared with those of a reference combined-cycle power plant without CO2 capture. Advanced exergy-based methods are used to (a) quantify the potential for improving individual components or overall systems, and (b) reveal detailed interactions among components-two features not present in conventional analyses, but very useful, particularly when evaluating complex systems. In an advanced exergoenvironmentai analysis, the environmental impacts calculated in a conventional exergoenvironmentai analysis are split into avoidable/ unavoidable (to evaluate the potential for component improvement) and endogenous/exogenous (to understand the interactions among components) parts. As in the reference plant, the potential for reducing the environmental impact of the AZEP has been found to be limited by the relatively low avoidable environmental impact associated with the thermodynamic inefficiencies of several of its components. However, although the environmental impacts for the majority of the components of the plant are related mainly to internal inefficiencies and component interactions are of secondary importance, there are strong interactions between the reactor and some other components.
