Costs are generally defined as the monetary value of the resource consumption for producing a commodity or service, frequently expressed as a composite sum of quantities of some activity multiplied by their respective prices [ 6].
The number of pills per day was calculated as the sum of the quantity dispensed divided by the number of days supplied.
For each diagnosis (out of six available) documented by each nurse, the sum of the quantity and quality criteria score was computed.
In order to facilitate this comparative analysis, we assume that the sum of each quantity in its active plus its inactive form is constant, with an arbitrary default value of 100.
To examine the relationships between gene expression and gene structure for Arabidopsis and rice genes, I firstly calculated Spearman's rank sum correlation coefficients between various structural parameters and total expression level (Exp tot, the sum of expression quantity of a gene acrosss tissues where the gene is expressed).
Xylose present in the digested xylan was the sum of the quantity of each of these digestion products multiplied by the number of xylose residues present in each structure: total Xyl = ((Xyl)1 x 1 + (Xyl)2 x 2 + GlcA Xyl)3 x 3 + MeGlcA Xyl)3 x 3).
Based on a previously validated algorithm, a patient is considered to be not well controlled if the sum of the quantity of all SABA medications dispensed to the patient within the past 3 months exceeds 250 doses i 21 and/or they visited an ED for a respiratory-related problem in the past 3 months.
Equation 4 denotes that the left quantity for each commodity and distributor in each period can be calculated by the sum of transported quantities to customers subtracted from the sum of transported quantities to a distributor added to the left quantity in the previous period.
Therefore, the absolute sum of these quantities is a measure of the disparity coherence in the direction from k 1 to k 2. We can write R k 1, k 2 ( m, n ) = | d k 1, k 2 ( m, n ) + d k 2, k 1 ( m, n + d k 1, k 2 ( m, n ) ) | (3).
A weighted sum of these quantities constitutes the value of the quality method.
