Nucleic acid extracted from dormant cane phloem of
grapevines affected by grapevine stem-pitting disease (SP)
formed a high molecular weight (MW) band on 1.0% and 0.8%
agarose gels. The band was unique to diseased vines. Other
bands appeared from samples of both diseased and virus-free
vines, but did not associate...
The behavior of the shore crab Hemigrapsus oregonensis was assessed
with and without exposure to polychlorinated biphenyls (Aroclor 1260).
After describing the crab's behavioral repertoire, activity budgets were
developed from observations of the time crabs spent in 20 categories of
shelter use, posture, and activity while held in habitat replicas...
Hemocyanins are oxygen transport molecules found only in molluscs and
arthropods. They are very large molecules with molecular weights in the
range of several million Daltons. They are multisubunit aggregates and their
oxygen binding site contains a binuclear copper center. Molluscan and
arthropodan hemocyanins are fundamentally different in structure and...
A software system to study network algorithms was implemented on UNIX. Each part of a network algorithm can be written as a single C program which becomes a virtual node in the network. During a simulation all virtualized nodes run as separate processes on a single PDP 11/44. Inter-node communication...
A statistically consistent and physically realistic approach for validating vector magnitude measurements is developed, based on a model for random measurement noise that explicitly satisfies a nonnegativity constraint for all “noisy” vector magnitude measurements. Numerical and analytic approximations are used to quantify the nonlinear functional dependence of sample conditional means...
The Self-indicating Instant Radiation Dosimeter (SIRAD) is credit card size, self reading, single use dosimeter produced by JP Laboratories. The SIRAD has a chemical strip that changes color based upon incident radiation. The color change is instantaneous and cumulative. The card was designed for first responders as a way for...
