Although the Escherichia coli host has almost all of the enzymes necessary to
synthesize nucleotides needed for bacteriophage T4 DNA replication, phage genes
expressed early in infection encode enzymes for de novo DNA precursor biosynthesis
and salvage from degraded host DNA. Eight early enzymes and two host enzymes
comprise the...
The main objective of this research was to assess the
nutritional status of sheep and goats grazing two rangeland
types in Baluchistan, Pakistan. These types were Artemisia
maritima/Haloxylon griffithii association represented by the
Zarchi Field Station and Cymbopogon shoenanthus, found at
the Tomagh Field Station. Seasonal above ground biomass
production...
This thesis examines the cultural context in which Japanese children are constructing their
own perspective of the environment because in the development of environmental education in
Japan, the perspectives of children and teachers have not been taken into consideration. Although
educators have made efforts to give direction to environmental education,...
For the first time in several years, the El Niño-Southern
Oscillation did not dominate regional climate conditions
around the globe. A weak La Niña dissipated to ENSOneutral
conditions by spring, and while El Niño appeared
to be emerging during summer, this phase never fully
developed as sea surface temperatures in...
Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of...
Although it is well-established that the fatty acid profile of breast milk will
reflect the dietary fatty acids, the response time with which this occurs is not
known. We hypothesized that fatty acids from a given meal would be transferred
acutely from chylomicrons into breast milk. To test this hypothesis,...
The Central Oregon High Cascade Range is an anomalously mafic segment of the
Cascade Arc due to ongoing intra-arc extension, which allows most magmas to traverse
the crust without stalling and evolving to more evolved compositions. North Sister, a
composite volcano in this arc segment, has produced a seemingly monotonous...
One of the biggest open questions in physics is the prevalence of matter over anti-matter in the present universe. One of possible answers lies in the violation of charge and parity symmetry in the lepton sector that would favor matter over anti-matter so that the universe becomes dominated by matter...
