'without presence of' is correct and can be used in written English.
It is often used to denote the absence of something, or the lack of something being present. Example: The building was silent and dark, without presence of any other people.
showed upregulation when measured using supernatant harvested from splenocytes grown with or without presence of ConA.
Our results show a relatively good agreement between gravimetric and seismic models, without presence of a significant systematic bias.
The response of the sensor is investigated in two cases: with and without presence of a ground plane and for various materials with different dielectric constants.
Without presence of high molecular weight capping agents, tiny Pt nanoparticles (<3 nm) are prone to agglomeration due to Oswald ripening.
The present study described laboratory setup and data for the driving simulator experiment, and drew conclusions on driver compliance to roadside safety signs with and without presence of AWS.
The study results showed that the addition of bio-binder led to a reduction of viscosity in the RAS modified binder to be closer to that of the virgin binder (without presence of RAS).
The simultaneous reduction of N2O by CO and direct N2O decomposition took place when CO was limiting reactant (CO/N2O < 1) but only at temperatures, at which the direct decomposition is possible without presence of reductant.
Continuing excess of CO over N2O without presence of O2 led to a very slow reduction of the catalyst, which caused noticeable N2O conversion decrease with progressing catalyst reduction.
The addition of surfactant at a concentration of 1.5 g/l in the coating reveals a significant improvement in the rate of deposition, wettability, and corrosion resistance with a sharp decline in the surface roughness (Ra) as compared to the coating obtained without presence of surfactant in solution of the bath.
The reduction of as prepared catalysts by 10% H2/Ar at 673 K led to formation of well dispersed active metallic phase with average nickel particles size ∼11 nm. 2 wt.% Ni/CST-A was examined as a catalyst in hydrodechlorination (HDC) of trichloroethylene in liquid phase, without presence of an additional organic solvent in the reaction mixture.
The above-described process is appealing because it can operate without presence of a PSSR.
