For instance, studies of the task-based research have collected data using computer-delivered (e.g., Ellis 2005) or tape-based monologic tasks (Elder and Iwashita 2005; Iwashita et al. 2001; Wigglesworth 1997) in an effort to control for covariates in experiment designs.
For instance, studies of the biosimilar filgrastim XM02 have found the level of impurities evident in the XM02 product to be less than those found in Neupogen® [ 36].
For instance, studies of the British Cohort and nationally representative sample of the U.S. population both reported an inverse association between serum 25(OH D concentration and metabolic syndrome [ 21, 23], but another study in obese population did not find such a association [ 24].
For instance, studies of the sea squirt Ciona intestinalis, pea aphid Acyrthosiphon pisum as well as honeybee Apis mellifera demonstrate that DNA methylations in these species are targeted to "gene bodies" or transcriptional units rather than nongenic regions (Wang et al. 2006; Suzuki et al. 2007; Elango et al. 2009; Feng et al. 2010; Walsh et al. 2010; Zemach et al. 2010).
For instance, studies on the use of antibiotics are warranted given the increasing numbers of resistant bacteria and the relation to antibiotics use[ 22].
In some instances, studies of the same species under different environmental conditions have arrived at different results regarding the distribution of the divergence pattern (see, e.g., Hohenlohe et al. 2011; Roesti et al. 2012; Gagnaire et al. 2013).
8 14 For instance, studies of college athletes in the USA have found significantly higher levels of binge drinking among male (61%) and female (50%) college athletes compared with males (43%) and females (36%) not involved in college athletics.
For instance, a study of the impact of switching a million hectares of pastures and hay lands to energy crops (mainly switchgrass and corn stover) on the water quality in the Upper Mississippi River showed an ambivalent effect [19].
For instance, a study of the MLH1 gene in gastrointestinal cancer found that the methylation of an Alu element in the first intron spread to its promoter.
In view of the close fit, the models with solid railpads can be used for track and fastening design and to derive track parameters to, for instance, study the deterioration of tracks.
