As zircon U-Pb geochronology has become a leading method in sediment provenance studies and basin analysis over the past 20 years, volume of detrital data made available published literature enabled researchers to go beyond source-to-sink explore increasingly complex geologic problems. In this review, we utilize growing body acquired from Jurassic-Paleocene forearc foreland strata North America...

Th is experiment compared linear relationships among end-products of rumen fermentation measured at the time (t1⁄2) at which a feed produces half of its asymptotic gas production) or at 48 h. Meadow hay and corn grain were incubated for t1⁄2 (16 and 9 h, respectively) or for 48 h into glass bottles. Each bottle (310 ml) was fi lled with feed sample (0.5 g) and 75 ml of buff ered rumen fl uid, a...

d before initiating treatments. Cows were blocked by lactation number and assigned randomly to 3 treatments consisting of variations of the Ovsynch protocol. Cows in Cosynch-48 and Ovsynch received injections of GnRH 7 d before and 48 h after a PGF injection. Fixed-time inseminations (TAI) were made at the time of the second GnRH injection (0 h; Cosynch-48) or 24 h (Ovsynch). Those in Cosynch-7...
