Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...
The purpose of this work was to design a system for measuring
the velocity of a powder actuated fastener or drivepin during penetration.
This system would provide a tool for further investigation
into drivepin penetration characteristics. The main characteristic
of interest is the instantaneous acceleration from which the forces
on...
It is desirable to be able to describe an automobile mathematically
because of the large number of variables which affect automobiles'
handling characteristics and of the high cost of building prototypes.
A mathematical analysis facilitates the construction of a
few prototypes whose configurations look most promising.
Equations of motion were...
Six serotypes of calicivirus (San Miguel Sea Lion Virus types 4,6,7
and 13, Mink Calicivirus and Reptile Calicivirus) were plaque purified,
and two-dimensional gel electrophoresis fingerprints, of the ³²P-labeled
Ribonuclease T1 digested viral RNA, were performed for each serotype.
Fingerprints revealed several oligonucleotides with similar mobilities,
and therefore, possibly similar...
Serum samples from 1,046 Kansas cattle were examined for the
presence of neutralizing antibody to caliciviruses known to be
circulating in the marine environment. All sera were from farm-origin
cattle, with the number tested being proportionate to the total number
of cattle in each county. These sera were selected in...
