    Article Title: Nematicidal activity of furanoeremophilenes against Meloidogyne incognita and Nacobbus aberrans.
    Article Snippet: BACKGROUND: While searching for novel small molecules for new organic pesticide agents against plant-parasitic nematodes, we found that the hexane extract from the roots of Senecio sinuatos and its main secondary metabolite, 3⊎-angeloyloxy-6⊎hydroxyfuranoeremophil-1(10)-ene (1), possess nematicidal activity against the second stage juvenile (J2) of Meloidogyne incognita and Nacobbus aberrans.. Both species reduce yield of various vegetable crops.. These results encouraged us to synthesize esters 3–9 formed by diol 2, obtained by alkaline hydrolysis of 1 and acetic anhydride, benzoic acid, 2-nitrobenzoic acid, 2-bromobenzoic acid, 4-nitrobenzoic acid, 4-bromobenzoic acid, and 4-methoxybenzoic acid, respectively.

    Article Snippet: The covariation among average concentrations of C, N, Po and their element ratios was determined by pair-wise Pearson correlation coefficients (SAS Institute Inc., 2014).

    Article Title: Is normalized hindlimb length measurement in assessment of thyroid disruption in the amphibian metamorphosis assay relevant?
    Article Snippet: 1164 © 2019 John Wiley & Sons, Ltd. Abstract The amphibian metamorphosis assay represents an OECD Level 3 and EDSP Tier 1 ecotoxicity test assessing thyroid activity of chemicals in African clawed frog (Xenopus laevis).. To evaluate the effectiveness of snout‐vent length (SVL) normalization of hindlimb length (HLL), correlation between the HLL and SVL or body weight was evaluated in the control groups of 10 individual studies from three laboratories.. Two studies required separate analysis of the Nieuwkoop‐Faber (NF) stage ≤60 and >60 animals creating a total of 12 data sets.

    Article Title: Effects of Fructose or Glucose on Circulating ApoCIII and Triglyceride and Cholesterol Content of Lipoprotein Subfractions in Humans

    Article Title: Errata and Corrigenda in the OHNS Literature.
    Article Snippet: SAS Institute Inc. Spearman Rank correlation coefficient was computed to describe associations between IF and error occurrence and Pearson’s correlation coefficient was used to describe associations between IF and time between publication dates (online publication date of original article vs online publication date of error).

    Article Snippet: .. All data were subjected to statistical analysis of variance (ANOVA) using the following SAS models: GLM, Duncan’s multiple-range test, nonparametric Kruskal–Wallis test and Pearson correlation coefficient were used to assess dissimilarity in soil variables between the bird habitat and the corresponding control areas during the observed seasons ( ). ..

    Article Title: An evaluation of a novel device for measuring eating, rumination, and inactive behaviors in lactating Holstein dairy cattle.
    Article Snippet: .. Pearson correlation coefficients (r; CORR procedure; SAS Institute Inc., Cary, NC, USA), concordance correlation coefficients (CCC; epiR package; R Foundation for Statistical Computing, Vienna, Austria), and Bland–Altman plots (epiR package; R Foundation for Statistical Computing) were used to determine association between visual observations and technology-recorded behaviors. ..

    Article Title: Assessing the effectiveness of agricultural conservation practices in maintaining soil organic carbon under contrasting agroecosystems and a changing climate
    Article Snippet: .. Statistical significance for the comparison of measured and simulated data was determined via linear regression (PROC REG), and Pearson correlation coefficients (PROC CORR) were calculated (SAS Institute, 2014). .. Mean square deviation (MSD) was partitioned into three components: lack of correlation, a nonunity slope, and squared bias, and were used to assess CQESTR’s performance (Gauch et al., 2003).
