The phrase "at harsh" is not correct and does not make sense in written English.
It seems to be an incomplete or incorrect expression, and without additional context, it is unclear how it could be used.
Example: "The conditions were at harsh levels, making it difficult to continue." (Note: This example is incorrect due to the phrase itself.)
Alternatives: "in harsh conditions" or "under harsh circumstances."
The inverse relationship between plant invasion and harshness could be driven by greater propagule limitation at harsh sites compared with more moderate sites.
The integrated system is capable of performing remote control and data acquisition at harsh environment.

Next steps: The current system works only at harsh pH levels.

The synthesis of bare maghemite (γ-Fe2O3) nanoparticles was accomplished by thermal co-precipitation of iron ions in ammonia alkaline solution at harsh reaction conditions, respectively.
Maximum glucose yields upon enzymatic hydrolysis were obtained after pretreatment at 210 °C for 10 min and yields were similar at harsher conditions.
Xylose yields increased with temperature and residence time up to 190 °C, but decreased at harsher pretreatment conditions since these led to xylan degradation and concomitant production of furfural.
The group was hit by the warm weather in October and November as much of its clothing is aimed at harsher conditions, such as fleeces and waterproof jackets.
These characterizations indicated that at milder conditions, the pretreatment exposed cellulose and hemicellulose for subsequent enzyme attack; at harsher conditions, the pretreatment destroyed cellulose crystallinity and gave higher glucose yields.
As a result, higher acidity was obtained at harsher treatment conditions, which in turn aids in a series of autohydrolysis process [ 25].
