Although a variety of discrete stereotyped response movements occur in plants, particularly in higher forms such as flowering plants, these autonomous movements usually occur too slowly to permit detection by casual observation.
An observational study is designed to permit detection of the most plausible hidden biases.
According to the literature (Ramanjaneyulu et al. 2008), the existing reagents for the photometric determination of copper permit detection of 0.025 to 30 μg/mL Cu.
The PCR reaction conditions were optimized to permit detection of the organism from agar plates, broth culture, frozen samples, dead fish tissue, and live fish in less than 5 h (8 h, if the more sensitive nested PCR is used).
A dual-cavity device containing 1.4 mg of C-X and 2.0 mg of C-B was capable of selectively and quantitatively capturing a mixture of 14 VOCs at low-ppm concentrations in a few minutes from sample volumes sufficiently large to permit detection at relevant concentrations for workplace applications with the μGC detector that we ultimately plan to use.
Fellow volcanologist Wes Hildreth said of Johnston, "I think Dave's dearest hope was that systematic monitoring of fumarolic emissions might permit detection of changes characteristically precursory to eruptions ... Dave wanted to formulate a general model for the behavior of magmatic volatiles prior to explosive outbursts and to develop a corollary rationale for the evaluation of hazards".
Thus, our time-course was designed to permit detection of gene expression changes preceding, including, and following the development of visible teratogenesis.
To permit detection of full-length Notch1 or Notch2 receptors on the cell surface, a single FLAG-epitope tag was inserted between the signal peptide and the first EGF-like repeat.
Because we cannot rule out this possible confound of microsaccades, it might seem that the present dataset should be recollected with an fMRI eyetracker that has a high enough temporal and spatial resolution to permit detection of microsaccades.
A group size of 10 volunteers per dose was chosen based on the distribution of antibody responses from previous clinical trials [22], [23], and would permit detection of at least a five-fold difference in antibody concentration between dose groups using a Mann-Whitney test, assuming a level of significance of 0.05 and a power of 0.80.
However, because we cannot rule out the possible confound of microsaccade/eyeblink rate, it might seem that the present dataset should be recollected with an eyetracker that has a high enough temporal and spatial resolution to permit detection of microsaccades in the fMRI scanner.
