The number of subjects included for each tracer might be a limitation for this study; however, typically first in man PET studies are limited in subject number and often restricted to healthy subjects.
For indoor measurements, the frequency-domain approach yields very good results, having limited applicability for outdoor measurements since the coax cable length is a strong limitation for this.
The experiments covered a size range of 2.4 6.5 mm, which is the manufacturing limitation for this kind of fin.
Furthermore, the dollar limitation for this period is the otherwise applicable dollar limitation for calendar year 2008, multiplied by 6/12.
However, the short plasma half-life which may be attributed to the metabolic oxidation to the pyridine-counterparts is considered as a major limitation for this class.
However, the primary limitation for this method is that the input loadings are difficult or impossible to be measured when the machine tool is under operational conditions.
To avoid the clipping and the loss of accuracy that is common to the TVD schemes near extrema, we develop monotonicity-preserving (MP) conditions derived from Suresh and Huynh [A. Suresh, H.T. Huynh, J. Comput. Phys. 136 (1997) 83] to locally relax the TVD limitation for this family of one-step schemes.
A review is presented of the design of suitable materials systems for joining by high-temperature plastic deformation, details of the joining techniques, microstructures and properties of the resulting composite bodies, and prospects and limitation for this type of joining technology.
However, data unavailability for some countries, variables, and earlier years is a limitation for this study.
However, another possible limitation for this study when compared to Tohka et al. [13] is the use of Van Cittert instead of reblurred Van Cittert deconvolution.
Lack of data availability was a big limitation for this study so I tried to include the time period in which data was available for all three variables.
