The diffuse presence of small copper ore deposits in the Alpine area, mostly exploited since Late Medieval times, led most scholars to assume that these deposits may actually be active much earlier and that many of the circulating prehistoric metal objects found in the area were produced with loc...

An Example of the Density Formula in Chemistry Let's say our lab has two compounds: A and B. Compound A is a ball that has a volume of 30 cm3and has a mass of 50 g. Compound B is a perfect cube with sides measuring 6 cm, and has a mass density of 500 kg/m3. What is the...
In order to adapt to a new niche, the animal needs to have access to its resources over a long period of time. This long-term availability is therefore another key feature of the paleo-synanthropic niche. When stable isotopes are used to define trophic niches, this is often done withδ13...
