Descriptors for terpene esters from chromatographic and partition measurements: Estimation of human odor detection thresholds [PDF]

open access: yes, 2020
We have used gas chromatographic retention data together with other data to obtain Abraham descriptors for 30 terpene esters. These include the air-water partition coefficient, as log Kw, for which no experimental values are available for any terpene ...

Chromosomal location of a gene that controls sterol esterification in Triticum aestivum L. [PDF]

open access: yes, 1974
A previously described D genome locus (Pln) that controls sterol esterification in the wheat kernel has been assigned to the short arm of chromosome 7 D by comparison of the steryl ester phenotype of euploid kernels of Triticum aestivum variety Chinese ...

L_1-distance for additive processes with time-homogeneous L\'evy measures [PDF]

open access: yes, 2014
We give an explicit bound for the $L_1$-distance between two additive processes of local characteristics $(f_j(\cdot),\sigma^2(\cdot),\nu_j)$, $j = 1,2$. The cases $\sigma =0$ and $\sigma > 0$ are both treated.

Structure, Conformation and Contact Analyses of Six Aromatic Diamide Diesters

open access: yesCrystals, 2023
Six meta-substituted isophthalamide diesters (DxE) and pyridinedicarboxamides (PxE) are reported with spectroscopic and crystal structure analyses (D = meta-C6H4; P = meta-pyridine; xE = 2-/3-/4-ethyl ester substitution). Comparisons are made between the
