The demand for biodiesel in the renewable energy sector continues to grow yearly. However, majority of sources currently still compete with food sector. Feun Kase seeds contain high oil and do not food, so they have prospects as a new source biodiesel. This study aimed find optimal conditions synthesizing from seed oil, carried out through transesterification four reaction variables: catalyst v...

Heritability estimates, by year of freshening of daughter, were obtained from daughter-dam and granddaughter-granddam regressions using 61,482 triply matched first lactations of artificially sired Holstein cows obtained from the Northeast Dairy Records Processing Laboratory. After adjusting for herd-year-season effects, residual effects may include additive and other genetic effects of the anim...

BACKGROUND Maternal smoking is associated with low birthweight (LBW). LBW prevalence is increasing in the US. However, it is unclear whether a fall in maternal smoking has any impact on the LBW prevalence in Massachusetts, a state with a comprehensive tobacco control program since 1993. METHODS Temporal patterns in prenatal maternal smoking and in LBW prevalence were quantified between 1989 a...

Marine calanoid copepods colonize new habitats, and some become invasive. Their fitness, measured by intrinsic growth rate and net reproductive rate, is partially driven by biochemical processes. Thus, it is a function of ambient temperature. Biochemical processes may not be approximated well by yearly mean temperature alone when temperature cycles yearly, largely. Higher order moments may also...
