The phrase "a usual value for" is correct and usable in written English.
It can be used when discussing a common or typical value associated with a particular context, such as statistics or measurements.
Example: "The average temperature in July is a usual value for this region, typically ranging from 75 to 85 degrees Fahrenheit."
Alternatives: "a typical value for" or "a common value for".
In these tests, each gene was compared against all the other gene trees and a usual value of p≤0.05 was used for the rejection of a given tree topology, suggesting that alignment reflects a non-vertical inheritance [22], [23].
Secondly, we have developed a mechanical model using finite elements analysis (FEA) calculation method: this one permits to obtain the optimal mechanical design of the device in order to achieve a 200 nm tuning range with a bias voltage of around 15 V (usual value for this kind of device).
In comparing the GA forecasts with observations, we obtain values of the Hanssen Kuiper skill score ranging from 0.463 to 0.727, which are usual values for similar forecasts of space weather.
In the case of styrene, the polydispersity index of the polystyrenes produced was relatively high (I = 1.2 to 1.5), but by adding small amounts of tetrahydrofuran or by using unpurified initiator, which contains polar impurities, the polydispersity index recovers the usual values, for molecular weights higher than ∼ 1 × 104.
First of all, the cobs need to be broken into pieces in order to match the requirements of the gasification system [17], furthermore, due to the porous structure, the dust content in the gas can be higher than the usual values for woodchips gasifiers [14, 15].
At a current level of 1 μA, a usual reference value for AC switches, the porous silicon structure demonstrates voltage capabilities higher than 520 and 350 V with positive and negative biases, respectively.
After using the principle of superposition, the multiple crack problem in a finite plate can be converted into two problems: (a) the multiple crack problem in an infinite plate and (b) a usual boundary value problem for the finite plate.
The latter departs from the usual value of 61 for nuclear genes as in invertebrate mitochondrial genomes 62 codons are in use (instead being a stop codon, UGA codes for tryptophane in the invertebrate mitochondrial code).
In the past, Christie's has sold jewelry from minor royals for only a little over their usual value.
