TIR imaging devices of the kind we used in the study typically have a fairly limited field of view.
Until 1981 what we knew about respiration and blood chemistry in Everest's 'death zone' was based on anecdotal accounts, studies at lower altitudes, extrapolations from mathematical models, and a fairly limited number of studies conducted, like Bert's, inside barometric chambers.
It is worth mentioning that unusually few independent variables were significantly associated with the outcomes which may be due to the current study's fairly limited sample size.
In addition to the small number of studies, the studies available presented fairly limited evidence for what can be effective in encouraging people who are well to discuss their end of life wishes with those closest to them.
The number and quality of games is fairly limited, but most work well.
The improvement was fairly limited, and the researchers said more study was needed.
Obviously, the target audience is fairly limited, as it is intended for those studying to take the standardized test to get into grad school.
Women in the study carried out, and knew about, a fairly limited range of pre-pregnancy activities, most commonly taking folic acid, avoiding alcohol, stopping smoking, and healthy eating.
Second, humanist discourse focused not on an imagined high-technology future but on current low-technology reality especially on the (fairly limited) range of alarms and monitoring devices available at the time of our study.
However, the number of studies focussing on self-perceived health of survivors is fairly limited, so that more research in this area is warranted.
