The treatment of waste water from a corn freezing process by
activated sludge with the aid of alum coagulation was investigated.
Both high and low energy level systems were observed with good
flocculation occurring at the low energy level. Because poor flocculation
occurs at high energy level conditions, alum was...
The structural behavior of pile groups (dolphins) is analyzed
considering two types of boundary conditions. First the individual
piles of the group are assumed to be rigidly embedded in the soil. In
the second analysis the more realistic case is considered where the
soil foundation is allowed to yield. The...
A recently developed statistical model for first-order scattered fields is used to predict
the normalized covariance function of an underwater acoustic signal backscattered by a
hypothetical school of fish. The fish school is configured as an oblate spheroid with the
individual fish Poisson distributed within the school.
Empirical covariance functions...
Purpose of the Study
In most liberal arts colleges, the majority of students enrolled
are primarily interested in a liberal education. To meet the requirements
of its students, several colleges have introduced a relatively
new program in the sciences; this program is the integrated
science course. This study attempts to...
A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...
Self-interactions (effects of reinoculation with the same nematode)
in Meloidogyne hapla and Heterodera schachtii on Beta vulpris at
different levels of inocula with various population combinations were
studied. In M. hapla, the only significant increase of galls was
noted in treatments when 250+250 larvae were inoculated at 10-day
intervals. Longevity...
