The ability of Cumella vulgaris to avoid burial under different
rates of sedimentation and to recover from burial once buried was
studied. Sedimentation rates higher than 0. 25 cm/mm are
necessary to bury 50% of C. vulgaris with the deposition of 4 cm of
sediment.
Cumella vulgaris can swim several...
A majority of eighteenth-century novels remain in regular print over two hundred years since their inception. Yet with the possible exception of Robinson Crusoe, they have largely fallen out of popularity, rarely appearing on "The Summer's Hottest Reading" lists or receiving celebrity endorsement. I consider Ian Watt's foundational study, The...
Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...
The purpose of this study was to investigate the relationships
between age, sex, eye-hand coordination, the time it takes individuals
to learn how to manipulate dental floss between all of their teeth, and
the time it takes individuals to learn how to effectively clean their
teeth with dental floss.
The...
Most general purpose protocols are found to suffer from
inefficiency in an Ethernet LAN environment when used for large
volume data transfer. This is especially true with the TCP/IP family
which was designed for a wide area network. This research work
presents a proof of this inefficiency and proposes a...
Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...
The major purpose of this study was to determine the current status
of family life/sex education programs in the public high schools of
Oregon. A mail questionnaire was submitted to all health teachers in
all the high schools in Oregon. The questionniare was mailed twice to
447 health teachers in...
An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
