Murals are more robust and a simple calculation using a yearly ammonia deposition on walls of 300 μmol m−2 [20], which when converted to nitric acid reacts with 0.03 g (CaCO3) m−2.
Using a simple calculation, the physiologic range for the phantom was determined.
Using a simple calculation, Grandjean et al. [ 31] also determined the molar concentrations of alkylphosphates in urine (adjusted for the body weight) corresponding to an oral reference dose (RfD) for the most toxic pesticides, as a worst case scenario.
Among the rare published studies on this aspect, one can cite that of Fenske et al. [ 26] in which dose estimates, reconstructed from biomarker concentrations using a simple calculation, were compared to the acceptable daily intake (ADI) of the World Health Organization (WHO).
This paper presents a scaling model that is capable of producing reasonable estimates of oil recovery for a SP flood using a simple spreadsheet calculation.
In this study, the motions of regolith particles on a vibrating plate in the Earth and Moon environments were firstly investigated using a simple model calculation.
By simple calculations, using a reverse transcriptase error rate of 3.4×10−5 mutations per site and generation [3], [4] and viral production rate of 1010 [7] it can be estimated that all nucleotides in the HIV-1 genome on average mutate about 105 times per day in an HIV-1 infected individual.
Although the optimal values of these parameters strongly depend on the process dynamics and require complex calculations, this work uses a simple benchmark to obtain general guidelines and illustrates the methodology for easily parameter tuning as a function of the process information typically available.
Thus for instance if there are 35 grams of carbohydrates, and 15 grams of fat and 20 grams of proteins, you use a simple calculation.
By identifying the isotopic effects of the different processes in soils we could use a simple isotopic calculation to estimate the extent of biological phosphate turnover in our experimental system.
