Despite these encouraging results, barcoding of terrestrial plants faces several challenges and limitations (Chase and Fay 2009), particularly for closely related species in which restricted variation in barcoding markers limits reliable identification; some plant genera have even been found to be refractory to barcoding (Piredda et al. 2011).
4 The limitations of this evaluation are associated with the small number of large randomised controlled trials available for inclusion, which restricted the number of agents that could be compared.
Second, previous tools were mainly developed for computational biologists, which restricted their wide use among experimental biologists.
However, very limited genomic resources are available for rubber tree, which restricted the development of modern breeding technologies.
Industrial emissions were based on a comprehensive database of industrial locations from 1970 to 1994; however, emission estimates were only available for major industries, which restricted the examination of specific industrial chemicals when minor industries were included.
If anything, the battle over Mr. Bloomberg's decision to revise the rule has intensified public support for the original measure, which restricted most officials to eight consecutive years in office: in 1993, it was adopted with 59 percent of the vote.
As a result, standard substance was indispensable for identifying the targets, which restricted its application in qualitative analysis.
Contiguous range expansion is also inferred for total cladogram B, which restricted to northeast China.
Part-time RNs reported working in isolation and sometimes struggled to find a consulting room for follow-up visits which restricted the availability of flexible follow-up appointment times to offer to participants.
Approximately 65percentt reported that winters were warmer than in previous years but they still experienced very erratic and severe cold during the winter for about 5-7 days, which restricted their activities with very destructive effect on agricultural production, everyday life and the health of people.
