It includes code for extremely precise ephemeris calculations. PV_ICE - An open-source tool to quantify Solar Photovoltaics (PV) Energy and Mass Flows in the Circular Economy, from a Reliability and Lifetime approach. Solar electricity Nowcasting - Build the world's best near-term forecasting ...
If Ca2+ ions were not removed, or demineralization was attempted by centrifugation, isotope fractionation occurred and δ15N values of some AA were significantly offset so that calculations of the trophic position returned erroneous results. The refined sample pretreatment and data calibration methods ...
, documented human occupation spanning the last 2700 years with fine geo-stratigraphic control and 102 radiocarbon samples. Remains of multiple plankhouses were documented. Occupation spans large-magnitude earthquakes, periods of climate change, and change in nearshore habitat. Our project began in ...
Cores and trenches drilled or dug in religious and secular buildings in the hilltop town of Bergamo (northern Italy) were investigated by means of micro/macrobotanical and pedochemical analysis to unravel the cultural vegetation history of the area during ca. seven centuries across the Bronze—Iron...
(as part of the salary), the employees at Väsby demesne and the amount of food distributed to different social groups, for instance the different groups of workers at the mine, charcoal-burners, prisoners, craftsmen, clerks and servants at the estate. The accounts and calculations for AD ...
feedinlib - Contains implementations of photovoltaic models to calculate electricity generation from a pv installation based on given solar radiation. Furthermore it contains all necessary pre-calculations. photovoltaic - A Python library used in photovoltaics. pvcaptest - Collection of functions and Jup...
2.3.2. Fatty acid calculations According to the FA trophic biomarker concept, specific FA and ratios of FA can be used as indicators for diet sources (Dalsgaard et al., 2003). Palmitoleic acid (16:1ω7c) and eicosapentaenoic acid (EPA; 20:5ω3) are indicative of a diatom-origin diet,...
Radiocarbon age of regional groundwaters points to residence times of 20–30 Ky. Villafáfila lakes are through-flow lakes nourished by meteoric waters (direct precipitation and shallow groundwaters) as deduced by stable isotopes (δ18OH2O,δDH2O), while the solutes are provided by ascendant deep...
