The average size and age of chinook salmon (Oncorhynchus
tshawytscha) caught in commercial fisheries along the Pacific Coast
of North America have decreased substantially in this century. These
declines might be caused in part by changes in size and age at
maturity within the stocks contributing to those fisheries. Upriver...
The most important part of parallel computation is communication. Except in the most embarassingly parallel examples, processors cannot work cooperatively to solve a problem unless they can communicate. One way to solve the problem of communication is to use an interconnection network. Processors are located at nodes of the network,...
Regression testing is an expensive software engineering activity intended to provide confidence that modifications to a software system have not introduced faults. Test case prioritization techniques help to reduce regression testing cost by ordering test cases in a way that better achieves testing objectives. In this thesis, we are interested...
PCR-based codon-specific random mutagenesis and site-specific mutagenesis were performed to construct a library of 18 amino acid changes at Arg276 in the conserved leucine-loop of the core catalytic domain of human uracil-DNA glycosylase (UNG). Each Arg276 mutant was then overproduced in E. coli cells and purified to apparent homogeneity by...
Volatile compounds of eight pear varieties were isolated and identified by
GC/MS. A total of 112 components were identified from headspace of intact fruits,
including 47 compounds reported for the first time in pear. The volatile profiles of
these pear varieties were characterized by esters, alcohols, hydrocarbons, aldehydes
and ketones....

This report presents CTD observations of temperature and salinity as a function of hydrostatic pressure in the Kuroshio Extension in May 1981. Lowerings were made from the surface to the bottom along 152°E about every 30 nautical miles between 29°N and 41°N. Identical sections were made in July 1980 and...
