It is assumed that an important regulator of bacterial metabolism is substrate availability, especially the ratio of available fermentable carbohydrate to nitrogen (protein) [ 20, 21].
The acquired data from a National forefront tire industry shows the OEE in three ratio measurement of availability, performance, and quality with 78%, 82.5% and 99.8% of scorecard respectively.
In this analysis plant trait was included as a dependent variable, with a factorial combination of nitrogen mixture (categorical, nitrate + glutamine, nitrate + asparagine, glutamine + asparagine) and the log ratio of nitrogen availability (continuous, e.g. 0.1 mM:0.9 mM = log(1/9) = −0.95) as fixed effects.
The ECOP objective function is defined as the ratio of power output to the loss rate of availability.
The EPC (Exergetic Performance Coefficient) criterion defined as the ratio of total exergy output to the loss rate of availability.
Information about the recommended minimum service coverage, staffing, equipment and availability of staff housing for each type of HF were extracted from official documents [24, 27, 28] and used to calculate for each item the ratio of the actual availability and the minimum set by norms.
Grid preference was calculated as the ratio of use to availability [19], where a value of >1 indicated a preference and <1 indicated avoidance of an area.
Advantages of Cu-ATSM include, rapid uptake, strong signal to noise ratio, the availability of a variety of Cu isotopes with variable half-lives and emission spectra, and some potential for therapeutic as well as diagnostic utility [ 46- 48].
Gel filtration, native PAGE, and protein cross-linking were used to analyze the size heterogeneity of nascent HDL produced by BHK-ABCA1, RAW 264.7, J774, and HepG2 cells under different levels of two factors considered as a ratio, the availability of apolipoprotein AI (apoAI) -accessible cell lipid, and concentration of extracellular lipid-free apoAI.
On the other hand, population-staff ratio and availability of infrastructure for basic emergency obstetric care (BEmOC) services had significant positive influence on unit costs (p���= 0.022 and p = 0.029).
