The phrase "activity is constructed" is correct and usable in written English.
It can be used in contexts discussing how activities are designed, developed, or organized, particularly in educational or theoretical frameworks.
Example: "In this course, we will explore how each learning activity is constructed to enhance student engagement and understanding."
Alternatives: "activity is designed" or "activity is developed".
To evaluate this problem, a reactor performance model with time varying catalyst activity was constructed.
In addition, mutants of SMO with altered substrate preference and enhanced activity were constructed, which indicated great potential of SMO for further improvement.
Microdrives used for recording neuronal activity were constructed from methods adapted from Gray et al. (1995).
Despite this, a more accurate alternative model of the cortical activity was constructed, namely a series of dipoles spread over a region of the cortex.
An estimate of motor activity was constructed from a simple reaction time task, and the motor estimate was subtracted from the button-press P300 according to Kok's formula [ 9]: true P300 = go P300-motor potentials.
The seminal papers of Prevoo et al in 1995 18 and Aletaha et al in 2005, 7 where DAS28 and its cut-offs for disease activity were constructed, are therefore discussed.
In this study, 'healthy' behaviours (e.g. healthy diet and regular physical activity) were constructed as both manly and lifesaving within particular contexts where this was permissible (e.g. the Fire Fighters Group).
In previous works from our laboratory, machine learning protocols for distinguishing MTDs from a general body of cytosolic protein domains know to have no membrane-binding activity were constructed using support vector machines (SVM) (Bhardwaj et al., 2006) and later on extended using other classifiers (Langlois et al., 2007).
Some areas of technological endeavor, however, represent foundations upon which economic activities are constructed.
Following the extraction of the modules, a module activity matrix is constructed for the training data as well as the validation data (Figure 1, Step 4).
