Second, efficiency implies generating "more service per unit of resource" [68].
It is possible that improvements in yield through breeding have come at the expense of roots and capacity for water and nutrient uptake, and therefore old and new cultivars should be compared to determine if selection programs are causing application efficiencies (uptake per unit of resource applied) for water and nutrients to decline.
This formulation attempts to explain human consumption in terms of three components: population numbers, levels of consumption (which it terms "affluence", although the usage is different), and impact per unit of resource use (which is termed "technology", because this impact depends on the technology used).
If individuals have access to a common resource, they can either exploit it rapidly (increase the energy produced per unit of time) or efficiently (increase the amount of energy produced per unit of resource consumed).
Establish the cost per unit of resource.
Direct medical costs of performed tests were calculated as actual volumes of resource use multiplied by the costs per unit of resource.
To perform the cost calculations, the volumes of (healthcare) resource use are multiplied with the cost prices per unit of resource use.
When F increases, GOOD habitats can receive more females per unit of resource, and the sex ratio is then more biased towards females in GOOD habitats.
Globally, industrial strains had a large cell size, reproduced slowly, reached a low carrying capacity and produced a weak biomass per unit of resource consumed (Table 4).
The costs per unit of resource use were calculated as actual economic costs, that is, including medical staff, other personnel, disposables, fixed equipment and a mark-up for fixed costs and overheads (Finkler, 1982).
A high rate of ATP production per unit of time is associated with a high reproduction rate and is considered as a selfish strategy, whereas a high yield of ATP production, i.e. the number of units of ATP per unit of resource consumed, is associated with a low reproduction rate but with a high biomass production, and is considered a cooperative strategy.
