Variation in the dataset may reflect differences in developmental stage and health between plants, but also differences in extractability of specific components (e.g. lignification might hinder extraction of wall components) and tissue- and cell-type specific differences in cell wall composition.
Shale oil and gas are more abundant than had been thought but the report also listed factors that may hinder extraction outside America, including lack of expertise and the absence of private land rights to spur development.Location, location, locationGoogle bought Waze, an Israeli developer of a popular mapping-and-traffic smartphone app.
This is found to be related to carrier collection problems, namely, hindered electron extraction and retrapping in the CLs.
The UV light causes photodoping of TiO2 where oxygen is chemisorbed at those sites, leading to unfavorable band bending in the TiO2 and thereby hindering charge extraction [78].
A number of design decisions in the implementation of pathway databases can hinder the extraction of this fundamental information.
Chemical modifications on the other hand not only hinder RNA extraction but also impede reverse transcription and amplification reactions (Godfrey et al, 2000; Lee et al, 2005b).
IF confirmed these results for Huperzia, and further suggests that pectic HG might not be a major constituent of their cell walls or that these species have distinct cell wall architectures that hinder the extraction and/or detection of pectic homogalacturonans.
In particular, in the low frequency regime, the hindered diffusion-controlled extraction of anions from the bulk of the film is also evident from the larger RD as compared to RCT and the difference in their magnitudes is more pronounced for the functionalized film thus confirming that functionalization is a useful method for controlling the redox response of conducting polymer films.
A decrease in pore-water velocity provided a longer residence time for greater Ni and Cu extraction, but also enhanced the rate-limited metal exchange of Zn EDDS and Pb EDDS complexes and thus hindered Zn and Pb extraction.
Data extraction is hindered by the presence of overlapping structures, varying focus, contrast, illumination levels and noise in the images.
