This thesis has four main results. First we find a reduction form
for symmetric matrices over fields of characteristic two. This result
parallels the diagonalization theorem for symmetric matrices over
fields of characteristic not two.
Secondly we reduce our reduction form to a canonical form in
perfect fields of characteristic...
In certain cases in system modeling, parameter search problems
are complicated by the availability of scanty and corrupt physical
system data and a large number of model parameters. An algorithm
using man-machine interaction is presented to attack this type
of parameter search problem with the objective of efficiency in the...
A systematic study of the elution of magnesium and calcium from
Dowex 50 X 8 resin using α-hydroxyisobutyric acid (α-HIBA) at
various pH values and concentrations, indicated that the difference in
the equilibrium distribution coefficients of these two elements was
large enough for a good separation. This fact was applied...
Methane is the most abundant organic chemical in the
earth's atmosphere. Its abundance in the atmosphere is
increasing with time and has reached levels not seen in recent
geological history. The methane is produced both naturally, and
anthropogenically. One of the sources of anthropogenic methane
is manure from domesticated animals....
Anthocyanin degradation in freeze-dried strawberry puree was studied under various relative humidity conditions at 37°C. Moisture was found to be the determining factor in the rate of pigment degradation. Storage at relative humidities below 11% provided good pigment retention in this low-moisture product. Enzymatic degradation of the anthocyanin pigment did...
