The value obtained is largely dependent on the susceptibility of the microorganism and the antimicrobial potency of the chemical, but other variables can affect results too. [5] The MIC is often expressed in micrograms per milliliter (μg/mL) or milligrams per liter (mg/L).
In England, a single pub measure (25 ml (0.85 US fl oz)) of a spirit contains one unit. However, a larger 35 ml (1.2 US fl oz) measure is increasingly used (and in particular is standard in Northern Ireland [37]), which contains 1.4 units of alcohol at 40% ABV. Sellers of spirits by the glass must state the capacity of their standard measure in ml.
Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool. Odor threshold ...
The liability-threshold model is a threshold model of categorical (usually binary) outcomes in which a large number of variables are summed to yield an overall 'liability' score; the observed outcome is determined by whether the latent score is smaller or larger than the threshold. The liability-threshold model is frequently employed in ...

A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
A computer program measures the results, determining the quantity or size of the fragments, at each data point, from the level of fluorescence intensity. [1] Samples which contain higher quantities of amplified DNA will have higher corresponding RFU values. [2] [3] An "RFU peak" is a relative maximum point along a graph of the analyzed data.
