The phrase "a simultaneous treatment" is correct and usable in written English.
It can be used in contexts where multiple treatments or interventions are applied at the same time, often in medical or experimental settings.
Example: "The study involved a simultaneous treatment of both the drug and the placebo to assess their effects on the patients."
Alternatives: "concurrent treatment" or "simultaneous intervention".
This is because the number of design variables is increased and a simultaneous treatment of design variables of different types requires working on quite complicated design spaces.
In contrast to the existing models, the new model allows a simultaneous treatment or arbitrary types of random process disturbances such as operation (processing, cleaning, transfer, set-up etc).
So, the study of dynamical equations on time scales allows a simultaneous treatment of differential and difference equations.
Since such a simultaneous treatment of 2-D multiplexed signals employing OTDM and WDM technologies (OTDM/WDM signals) is equivalent to time-frequency domain processing, ROADMs for OTDM/WDM signals should be developed based on it.
Without a simultaneous treatment of ecological and evolutionary timescales, these dynamics could not be discerned and examined.
A simultaneous treatment with both compounds further strongly decreased the defect density, thus leading to an improvement in the material performance, especially in terms of stability against photodegradation.
A simultaneous-treatment design was employed to compare the rate of acquisition of "reading and writing" skills to the rate at which the participants acquired receptive and expressive signs.
The findings of this pilot study were not powered sufficiently to demonstrate that mindfulness is an effective simultaneous treatment of comorbid alcohol and tobacco abuse.
A method for simultaneous treatment of an aqueous solution to photolytically sterilize microbial cells and photocatalytically decompose organic compounds was studied using an annular-flow photocatalytic reactor with a 6-W germicidal lamp (wavelength; 254 nm) as a light source.
AN-9 and DNA-specific antineoplastic agents synergistically inhibited the growth of Mm-A cells, and the simultaneous treatment was required to evoke the maximum growth-inhibitory effect.
A prophylactic treatment is defined as the treatment of healthy animals to prevent disease from occurring, whereas a metaphylactic treatment implies the simultaneous treatment in a shared compartment of clinically healthy animals and animals that showed clinical symptoms of the disease [ 25].
