Methods used in these investigations include experiments, surveys, case studies, and historical research.
We distinguish the following research methods: analytical (mathematical) modelling, empirical (commercial (external) or self-created database, experiments, surveys, case studies, other) and verbal-analytical studies.
[A methodological note: To conduct this study, we used GuidedTrack, a new platform designed by Spencer that makes it easy to create your own online experiments, surveys, and training programs.
The mouse and rat expression experiments surveyed expression levels across 30 and 61 tissues respectively of which 17 were in common.
Fitness costs in the refuge were detected in more than half of the experiments surveyed by Gassmann et al. 2009.
In their study, the HA gene was mutated at the nucleotide level, so their experiments surveyed only amino-acid mutations accessible by single-nucleotide codon changes.
For efficiency of experiments, surveys of four-day intervals showed highly significant differences and may be preferable in detecting changes over time where mouse models and experimental design allow.
The experiments surveyed in [ 1] are an order of magnitude smaller than the norm today, and it is reasonable to extrapolate that as the costs of sequencing drop precipitously, the average depth of sequencing in RNA-Seq experiments will increase by another order of magnitude in the next 3 years.
Original studies including the four types of primary research methods – existing data, experiments, surveys, and observation – that focused on the association between SSBs and HFSSFs prices and taxes and their corresponding consumption or energy intake or obesity-related outcomes were included in the present systematic review.
In this study, we conducted a hypothetical choice experiment survey to obtain the data for estimating consumers' benefits of pregnant women in Sennan area.
