Three forms of crystalline aspartame have been observed: two hemihydrate polymorphs and a dihemihydrate. The 13C CP/MAS NMR spectra of two of the forms of aspartame showed that certain carbons have up to three resonances due to different conformation

Within the hen's ovary, the theca tissue of small follicles that have not yet entered the preovulatory hierarchy is a major contributor to ovarian steroidogenesis. Relatively little is known about developmental stages in the theca layer within this p

Two experiments were conducted to examine the effect of the feeding of a high-energy diet during early gestation on survival of porcine conceptuses. In the first, 91 second-estrus gilts were inseminated 24 h after detection of standing estrus and ran
