The panspermia hypothesis lifts this major time constraint which I believe will bring more realism to future theoretical and experimental studies of biogenesis.
The retrospective non randomized design of our study was dictated by two major issues: time constraints and acceptability.
Their major concerns were time constraints and a lack of familiarity with the use of the PtDA, which were addressed by conducting a training workshop for the healthcare professionals before they use it with their patients.
The second major challenge was the time constraints of the planning process.
The majority of those who declined participation cited time constraints as the major reason (n = 91), some (n = 39) were unable to complete the survey without assistance due to current iris dilation procedures, and some declined because they thought the information was too personal (n = 32).
Low awareness of the extent of malnutrition in this patient group, lack of training and time constraints are major barriers that practice staff face.
In finding the correct gain, a major constraint will be the time constraints associated with the control loop (e.g. lags and windows of opportunity associated with the effects of an action and delays associated with feedback about the impact of the actions).
"I don't see how it can be done," said the director, Michael Blakemore, citing time constraints as the major issue.
Time constraints were a major barrier.
Potential participants who were unwilling to participate in the FGDs cited time constraints as the major reason.
