The combination of RF inhomogeneity in theirradiated regionof the sample coupled with the effects of pulse rolloff serves to effectively destroy any residual net magnetization. This “full cannon”11method may test the limits of the transmitter amplifiers and the power handling capability of the prob...
Multiplet test The multiplet position and multiplicity of the peaks in the spectrum are compared to those determined from a standard material. If the two match, then the sample passes the peaks comparison test. The peak positions and multiplicity are shown in the boxes on the spectrum. Peak A...
All magnetically distinct sets of protons give rise to NMR signals which take the form of various peak patterns, dispersed across a spectrum (Figure 2). A peak’s location corresponds to that nucleus’ magnetic response to controlled p...
Table 1 Fold change and p values of 14 metabolites in a t-test analysis Full size table Fig. 2 Univariate statistical analysis to compare the expression of individual metabolites in between the two genotypes. Metabolites that are upregulated in AS are shown in orange color and those downregulate...
I have set up your presentation as a full podcast episode and as a video recording, without the podcast. It totally works! Yay. Via the podcast your presentation begins around 13:02 minutes into this week’s episode. I learned so much about a area of study I didn’t even knew existed...
