In bit-miles, which are calculated the way Burlington Northern would calculate ton-miles, Cogent is moving information at the rate of 71 sextillion bit-miles a year.
In ToSIA, material flows are calculated in tons of organic carbon and the impacts are calculated by using multipliers for each material unit used in each process resulting in an impact total (Tuomasjukka et al. 2013b).
The corresponding TON = Nproduct/NPW was calculated (where TON is the mole number of converted DBT per mole of PW supported on KSF).
Assuming that these landfills are representative of the average Danish landfill, the total emission from Danish landfills were calculated at 20,600 tons y−1, which is significantly lower than the 33,300 tons y−1 estimated for the national greenhouse gas inventory for 2011.
Altogether, the scientists calculated, about 4,000 tons have been released so far, with an additional 270 tons emitted each year.
A few years ago a Utah scientist calculated that 98 tons of fern, cycad and conifer must have grown in the carboniferous era to turn up again 300m years later as a gallon of petrol.
The total annual CO2 emission of Mega Metallurgy (XM08) is calculated at 102,500 tons (Equation 2): X M 08 = MC M (2).
Based on NEE and carbon sequestered in Imola biomass [about 50%% of ODW biomass (Table 1)], soil carbon sequestration is calculated as 0.19 ton C/ton harvested DOW SRC and 0.26 ton C/ton harvested DOW VSRC biomass, which is higher than the data range in previous studies (6 24 % of the total above-ground woody biomass) [ 41– 41].
According to the amount of water and the concentration of silicon ions in the produced fluid, the total output of silicon ions was calculated which was 46.7 tons from June 1998 to June 2000.
Plot-level AGB values (in tons) were calculated using the allometric equation given by Chave et al. [30] for tropical, moist hardwood forests, which were upscaled at 1 ha.
