Solar gains are quantities of useful energy that vary over the day.
Implications for the 21st century, which are also discussed briefly by exploring the implications of an ACEGES-based scenario of oil production, are as follows: (a) the provision of adequate and affordable quantities of useful energy as a pre-condition for economic growth and (b) the design of energy systems as 'technology incubators' for a prosperous 21st century.
For each individual clinical visit and laboratory test, the following items were included in the costing exercise: consumables (quantity used and unit price), drugs (quantity used and unit price), equipment (quantity used, price, years of useful life, number of cases processed annually), and staff (staff category, working time breakdown).
In Methods we describe and develop a formal approach to describing and analyzing probe libraries and their relationship to target sequences which enables us to define a number of useful quantities in precise terms.
Equations are provided that can be used to calculate a number of useful quantities from Si MAS NMR data, including the fractions of tetrahedral sites that are occupied by Si or Al, or that are vacant.
New structural chemical formulae are presented for single- and double-chain tobermorite-based phases and equations are provided that can be used to calculate a number of useful quantities from Si NMR data.
We first formally define a PSG and a number of useful quantities computed from a PSG.
It should be amenable to the synthesis of useful quantities of this otherwise scarce yet highly promising anticancer agent[ 30] for further biological evaluation and should also enable structure activity-relationship structure activity-relationship
In addition, I present a number of useful quantities, including single-locus genotype probabilities, two-locus haplotype probabilities, and the fixation probability and map expansion at each generation along the course to inbreeding.
