I. REPRODUCTION AND LAMB PRODUCTION Relationships among hemoglobin (Hb) genotypes and reproduction and production traits were examined in 294 four- and five-year-old North Country Cheviot, Dorset, Finnsheep or Romney x Suffolk or Columbia-type crossbred ewes. Hb BB ewe lambs were youngest at first estrus and Hb AA ewe lambs were...

The present study examined involuntary attentional bias toward facial emotion expression. Particularly, the study examined two different attentional components for emotional processing, namely, orienting vs. disengagement. A cueing paradigm using two cue presentation times (250ms and 350ms) was used to determine if attention would be involuntarily captured by an irrelevant...
The interaction of basalt melt with mantle harzburgite at low pressure might result in silica enrichment of the melt by assimilation of orthopyroxene. Experimental tests of this hypothesis show that silica-rich liquids (56 wt %) are produced by melt-orthopyroxene reaction at 1200° to 1250°C. These silica-rich liquids are enriched in...
We propose alternative mechanisms for the origin of three unusual rock suites, high-Mg andesites, NaTi basalts, and arclike rocks, that have been dredged from the Woodlark basin, southwest Pacific Ocean. We show that the high-Mg andesites and NaTi basalts are associated with an unusually cool ridge environment. The cooling is...
Hydrothermal vents appear to be the tip of the subsurface biosphere in the ocean crust. The primary prducers in this biosphere are prokaryotes that tolerate a wide variety of physical and chemical conditions and are versatile in their use of inorganic compounds to drive metabolism. A synthesis of chemical and...
Two TaqMan-based real-time One-Step RT-PCR assays were developed for the rapid and efficient detection
of Raspberry bushy dwarf virus (RBDV) and Raspberry leaf mottle virus (RLMV), two of the most common
raspberry viruses in North America and Europe. The primers and probes were designed from conserved
fragments of the polymerase...
These first measurements of specific surface area (SSA)
of bulk samples of subsurface marine basalts were undertaken
to determine the potential area available for microbial
colonization. SSA ranged from 0.3 to 52 m2/g of basalt
with the lowest value coming from pillow basalt and the
highest value from breccia. The...
The alteration of subseafloor volcanic glass from three locations is qualitatively attributed to biological
(biotic) or chemical (abiotic) reactions on the basis of microscopic morphology of the boundary between
the unaltered and altered glass. Eleven-element composition of fresh basalt glass (sideromelane) and its
alteration products were determined by electron microprobe....
