The contribution of genetic effects to the variation in percent normal development observed in a bay mussel (Mytilus edulis L.) embryo bioassay was determined. A factorial breeding experiment
was accomplished in which 9 males were mated with 3 females. Each mating was repeated 10 times, yielding 270 mussel embryo cultures,...
The metabolism of Strongylocentrotus purpuratus (Stimpson)
was investigated at several levels of urchin organization. Some experiments
were performed with tissues from recently collected
(acclimatized) urchins, Other experiments were performed with tissues
from urchins held at one of two temperatures (acclimated) for
30 days.
Body-component oxygen consumption was measured for bodywall,...
Sphaeromyxa maiyai sp. n. (Myxosporidea:Myxiidae) is described
from the gall bladder of the Pacific tomcod, Microgadus proximus
Girard, from Newport, Oregon. The plasmodial (=trophic, trophozoite)
stage is discoid averaging between 1 and 2 cm. The spore averages
27.6 x 5. 6μm with pyriform polar capsules averaging 9. 3 x 3....
This thesis is concerned with the analysis of heat transfer in a tube with forced flow under conditions of an arbitrary variation of wall heat flux both axially and circumferentially. This total study is separated into two distinct problems which are presented separately. The first is the case of a...
