Some of these reports employed a laborious and/or technically challenging method to identify or clone only one single amplified gene.
Field experimentation is a challenging method for analysing air flows due to limited number of measurement points, cost, unstable weather conditions, and experimental errors.
Hospital physicians also pointed out that they would prefer to pursue intervention through new programmes for hygiene, although they also recognise it to be a challenging method of improvement.
Laser capture microdissection is a technically challenging method due to the small amounts of tissue and the variability that may be introduced at various stages of the analytical process, compounded by the effects of working with post mortem human tissue, and the present work involved extensive optimization and validation of the methods prior to study commencement.
An even more challenging method is to fill in the first "across" word, fill in the "down" word from the last letter of that word and complete the grid by adding the word that includes the last letter of each new word.
This method could be accomplished by either conducting a new clinical trial (a very expensive and ethically challenging method because ChEIs are considered to be the current standard of care in AD) or a retrospective post-hoc analysis of individual data from the 12 clinical trials that we included in our meta-analysis.
Genome complexity can be estimated by Cot analysis, which is a technically challenging method used in 86 published manuscripts prior to 1990 [27], but not in common use after the availability of massively parallel sequencing approaches.
The conclusion of the study is that social games, although methodologically challenging, are a promising method to communicate complex planning problems.
It is a challenging task to develop a simple method to detect the biologically important anion H2PO4− in aqueous solution.
One challenging method for increasing the performance of sedimentation tanks is to use baffles.
The excellent detector performance established in this test validates the detector design and supports the feasibility of the proposed challenging method of luminosity measurement.
