The phrase "at elevated ambient" is correct and usable in written English.
It can be used in contexts related to environmental conditions, particularly in scientific or technical discussions about temperature, pressure, or other atmospheric factors.
Example: "The experiment was conducted at elevated ambient temperatures to observe the effects on the reaction rate."
Alternatives: "under high ambient" or "in increased ambient".
Device performance was also assessed at elevated ambient temperatures, reduced ambient air velocities, and varying system pressures.
Then, three groups of gaseous contamination ADT were performed at elevated ambient temperatures of 40 °C, 50 °C, and 60 °C, respectively and the estimated lifetimes of the SPTRs under normal condition were obtained through acceleration model (Arrhenius model).
Second, it would be quite interesting to know the behavior of plant microbe interaction at rhizoplane of free floating aquatic macrophytes under elevated atmospheric CO2 and at elevated ambient temperature and on the development of new interactive combinations in freshwater regimes.
At elevated ambient concentrations, NO2 has been associated with exacerbation of asthma (Hajat et al. 1999) and an increase in daily deaths (Touloumi et al. 1997).
We ultimately focused on pretreating the biomass with gaseous ammonia, either at elevated or ambient temperature.
However, spraying of metals at elevated temperatures in ambient atmosphere is accompanied by enhanced oxidation.
The effect of RH on PEM fuel cell performance was studied at elevated temperatures under ambient backpressure using Nafion®-based MEAs.
This paper discusses the mechanical behavior of La0.2Sr0.8Fe0.6Ti0.4O3−δ (LSFT -Ce0.9Gd0.1O2−δ (CGO) (40:60 voLSFT -Ce0.9Gd0.1O2−δiCGOembranes at elevated temperatures in ambient air and slightly reducing conditions.
With respect to α and Fv/ Fm, the DK clone responded more to CO2 than the ALG clone and had up to 4% and 144 % higher values (for Fv/ Fm and α, respectively) at elevated than at ambient CO2, as compared with the ALG clone, which merely differed by 1 % and up to 7%% (for Fv/ Fm and α, respectively; clone × CO2 interaction).
On that background, root-bed restriction and elevated CO2 should result in an additive negative effect, as was observed by Arp (1991) as well as in our study by a stronger inhibition of biomass production at elevated than under ambient CO2 (steeper slope at elevated CO2 in Fig. 1D).
This is important as elevated CO2 concentrations stimulate root growth, in particular fine root production (Norby et al. 2004; Stiling et al. 2013), and thus a small root-bed size should restrict root growth much more at elevated than at ambient CO2 concentrations.
