Method A (compounds 3, 5, 9– 17, 17): 11 nBuLi (1.6 m in hexanes, 4 eq) was added to a solution of the corresponding heteroaromatic compound (4 eq) in anhyd THF (10 mL) at −78 °C and stirred for 1 h.
We tested our new method on a compound database containing 51 HSQC spectra.
We employed the restricted maximum likelihood method assuming a compound symmetry model as covariance structure since it provided the best model in an information criteria comparison.
We assigned a value of one-half the detection limit of the analytical method when a compound was not detected in a sample.
Generalized Estimating Equation (GEE) methods, using a compound symmetric working correlation structure, were used to model this dependence.
A new method for producing a compound refractive X-ray lens is described.
A testing method which uses a compound cylinder was also introduced to test the polymers under nearly confined conditions.
In this work we used a statistical response surface method to obtain a compound of virgin and recycled polypropylene on a competitive basis with the pure virgin material (MFI 10 g/10 min) used for injection molding.
The rodent uterotrophic assay, a standard method for assessing a compound's estrogenicity, offers a model for phenotypic anchoring, or linking changes in gene expression to specific pathologic changes.
