A constraint for using the microenvironment based exposure models (see equation above) is that the residence time of the person (termed the time activity pattern) needs to be known together with the pollution concentrations in each of the microenvironments at the time when the person is present.
It does not have any constraints for use in terms of a predefined website structure, data types or database tables.
The findings cast a shadow over the feasibility of achieving net zero carbon particularly for high-rise buildings due to geographic constraints for use of renewable energies, which encourages the exploration of emerging energy and carbon reduction technologies.
Regulatory constraints for use in BLP for the metabolic network in Figure 1.
There may be many cultural constraints for use of maternity services e.g. decision of the husband or mother-in-law which often over-rides that of the mother.
The biggest constraints for using BIM involved the contractors' environment, that is, either clients did not demand BIM or partners did not use BIM.
There was a consensus among the interviewees that the major constraints for using BIM included lack of demand from clients, lack of knowledge, and cost versus benefits issue.
(ii) The consistency constraints for using the same parking lot: each passenger agent should visit the same parking lot when parking and finding his/her car in the entire trip chain.
So I come frequently and try on many clothes, and finally, I buy more (Participant E)." "I go there frequently because there are no time constraints for using the fitting room and I feel free in the liberal environment (Participant C)." Regarding actions and interactions concerning the items the participants tried on, we can also consider interactions with family, friends, or other people.
Therefore, the construction workers (i) define situations with high levels of exposure at their current worksite; (ii) learn how technical control measures should be used to reduce this exposure; (iii) discuss constraints for using technical control measures; and (iv) define solutions to tackle these constraints.
