Effect of Superchilling on Preservation, Ripening and Senescence of Broad Bean Seeds by LI Die, LI Haiyan, ZHONG Shihong, FU Yuansheng, LI Meiqing, ZHANG Haiwei

“…Superchilling at −3 ℃ kept broad bean seeds fresh for up to 35 d, significantly slowing down the decrease in chlorophyll content and the increase in mass loss rate and color difference values during storage and maintaining the hardness well. Principal component analysis (PCA) showed that the optimal superchilling temperature was −3 ℃. …”

Physicochemical Properties and Fertility Assessment of Soils in Foumban (West Cameroon) by Vivien Piercy Lotse Tedontsah, Michel Bertrand Mbog, Gilbert François Ngon Ngon, Robert Christel Edzoa, Bernard Tassongwa, Dieudonné Bitom, Jacques Etame

“…Class three (03) includes soils with a poor level of fertility that are the hortic FERRALSOLS (plaggic) (FLchp) on trachytes and the cambic FRAGISOLS (plaggic) (FGcp) with an area of about 38.47 Km2. Principal component analysis (PCA) has revealed that the parameters that control fertility in Foumban soils are C/N, pHeau, Ca, CEC, OM, P, and Mg. …”

Detection of Adulterated Honey by Fluorescence Excitation-Emission Matrices by Tatjana Dramićanin, Lea Lenhardt Acković, Ivana Zeković, Miroslav D. Dramićanin

“…Statistical t-test showed that significant differences between fluorescence of natural and adulterated honey samples exist in 5 spectral regions: (1) excitation: 240–265 nm, emission: 370–495 nm; (2) excitation: 280–320 nm, emission: 390–470 nm; (3) excitation: 260–285 nm, emission: 320–370 nm; (4) excitation: 310–360 nm, emission: 370–470 nm; and (5) excitation: 375–435 nm, emission: 440–520 nm, in which majority of fluorescence comes from the aromatic amino acids, phenolic compounds, and fluorescent Maillard reaction products. Principal component analysis confirmed these findings and showed that 90% of variance in fluorescence is accumulated in the first two principal components, which can be used for the discrimination of fake honey samples. …”

Spatial distribution characteristics, ecological risk assessment, and source analysis of heavy metals in surface sediment of a reservoir in northwest China by Yufeng Xie, Ming Kong, Fei He, Rongrong Ying, Tao Long

“…The pollution index analysis shows that the heavy metals in the surface sediment of the reservoir are at an uncontaminated level, but arsenic (As) is within the pollution alert range; The potential ecological hazard index method shows that mercury (Hg) and cadmium (Cd) are the main ecological hazard contributing factors; Correlation analysis and principal component analysis suggest that As and Pb are mainly affected by human activities, while heavy metals chromium (Cr) and copper (Cu) mainly come from natural sources, while other heavy metals are simultaneously affected by both human activities and natural sources. …”
