Animal manure contains valuable plant nutrients which need to be stored until field application. A significant proportion of slurry nitrogen is volatilized in the form of ammonia (NH) during storage. This impacts human health, biodiversity, air and water quality and thus urgent action is needed to reduce NH emissions.

However, prior to statistical analysis, variance from sources other than the sample must be minimized through application of data pretreatment procedures. This is necessary to ensure that subsequent statistical analysis of the data provides meaningful results.
View Article and Find Full Text PDFFive neat diesel samples were analyzed by gas chromatography-mass spectrometry and total ion chromatograms as well as extracted ion profiles of the alkane and aromatic compound classes were generated. A retention time alignment algorithm was employed to align chromatograms prior to peak area normalization. Pearson product moment correlation coefficients and principal components analysis were then employed to investigate association and discrimination among the diesel samples.

Some of these impairments may be related to abnormalities of the caudate nuclei, which have been reported for autism.
Methods: Our sample was comprised of 8 high-functioning males with autism and 8 handedness, sex, and age-matched controls.
