The phrase "activity of this system" is correct and usable in written English.
It can be used when discussing the functions, operations, or processes that a particular system performs.
Example: "The activity of this system is crucial for maintaining optimal performance in our operations."
Alternatives: "function of this system" or "operation of this system".
In this study we have examined the SIF-GPP relationship of a Mediterranean pine forest during a naturally occurring intense heat wave in spring, when photosynthetic activity of this system is at its maximum24.
Controls were used to investigate the activity of this system versus positive and negative controls, as well as quantifying activity against direct intramuscular injection of expression plasmids.
Based on electronic structure analyses, the high catalytic activity of this system is attributed to the charge transfer and the orbital hybridization between the adsorbates and the Ru atom.
The color-generating activity of this system could be influenced by several factors such as buffer type, pH value, DNA sequence, reaction time, and concentrations of both the hemin and H2O2.
The relevance of the ubiquitin proteasome system (UPS) to disease and fundamental cellular processes has generated a demand for methods to monitor the activity of this system in living cells and organisms.
An investigation of biological activity of this system is ongoing and will be reported.
Individuals using this computer system without authority or in excess of their authority are subject to having all of their activities on this system monitored and recorded.
The proteolytic activities of this system was isolated as a multi-protein complex originally called the multi-catalytic proteinase complex by Sherwin Wilk and Marion Orlowski.
More commonly, a reduced activity of the system is observed and this may contribute to the pathogenesis of thromboembolic diseases [ 1, 2].
In this work, we employed the Miami Isopycnic Coordinate Ocean Model to investigate whether the rich mesoscale activity of this current system, between 20°S and 28°S, is reproduced by a two-layer approximation of its vertical structure.
Here, we quantitatively analyse the long profiles of rivers that drain southwards across the South Atlas Fault (SAF), a thrust fault that forms the southern margin of the High Atlas Mountains in Morocco, to derive new data on the Late Cenozoic activity of this fault system.
