Additionally, more complex cost supply curves can also be implemented, which use a combination of geographical and economic variables to determine the potential distances travelled for harvesting the biomass (e.g., using various cost accounting methods) [74 76].
This can in part be explained by a more complex case mix, higher costs of labour, the cost of medical graduate education, or the use of more sophisticated technology [ 37].
As semiconductors have grown more complex, costs have skyrocketed to maintain Moore's Law.
Where antibiotic consumption is low, the vaccination scenario is more complex: cost-savings would need to be accumulated over several disease categories associated with the two main OM pathogens [ 44, 59] and the benefits, including indirect protection, may need to be measured and accumulated over the severities and prevalences of these same categories.
More than 100,000 small retailers, many on eBay and Etsy, use Outright to calculate the state sales tax they owe on transactions processed by PayPal, according to Steven Aldrich, chief executive of Outright Inc. (The basic online bookkeeping service is free and a more complex one costs $9.95 a month).
By contrast, a single U.S. Space Shuttle mission (albeit intended for orbital flight, a more complex affair) costs $500 million.
A more complex system, ReAqua+, costs an extra £1,000 but will also recover 50% of the heat in the greywater.
EPA's proposal would support a move away from the straightforward and effective method of testing selenium through direct water sampling, toward a more complex, burdensome and cost-prohibitive method of sampling fish tissue.
A more complex and contentious SCR can cost more than £100,000.
