The phrase "at the same duration" is not correct in standard written English.
It is typically intended to convey that two or more events occur for the same length of time, but the phrasing is awkward.
Example: "The two tasks should be completed at the same duration to ensure efficiency."
Alternatives: "for the same length of time" or "over the same period".
The negative control sections were incubated with a rat IgG2a isotype solution (AbD Serotec) at the same duration, concentration and temperature as the primary antibody.
In these 16 distractor presentations, each of the four presentation durations was chosen four times, but no distractor stimulus was shown at the same duration twice.
† p < 0.05 versus the DJW group at the same duration of treatment.
30 In our study, very preterm small for gestational age children exposed to pre-eclampsia had a risk of cerebral palsy comparable to unexposed children born at the same duration of pregnancy.
In children born very preterm, pre-eclampsia alone was associated with a reduced risk of cerebral palsy, whereas if the exposed child also was small for gestational age, the risk for cerebral palsy was not statistically different compared with unexposed children born at the same duration of pregnancy (table 3).
Control patients were randomly selected from the same population, admitted for at least the same duration until the index moment, without previous hypoglycemic events.
The subsequent smears of the control-women were typically obtained after the diagnosis of cancer in the corresponding women with cancer, as absence of disease in the controls for at least the same duration of follow-up was an essential component of the study design.
For every sampling time there was a corresponding control, consisted of flies kept at 25°C for the same duration (n = 4×20 flies).
As can be seen from the plot, 48 h incubation stimulates higher amount of drug release than 24 h incubation at 37 °C for the same duration of field exposure.
Agarose samples were polymerized for 24 h at 8°C, PVA samples for the same duration at -20°C.
For example, progression may accelerate with increasing age so that the rate of progression is 2-fold faster at age 60 than it would be at age 30, given the same duration of disease and other characteristics.
