Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...
Biological, serological, and molecular characteristics
of the P4 pathotype of pea seedborne mosaic potyvirus
(PSbMV) were investigated. The characterization allowed P4
to be differentiated from other pathotypes of the same
virus.
P4 was distinguished from P1 on the basis of host
symptomatology. It induced varied, but often distinctive
symptoms in...
We introduce a numerical criterion which allows us to bound the degree of any algebraic integer having all of Galois conjugates in an interval of length less than 4. Using this criterion, we study two arithmetic dynamical questions with local rationality conditions. First, we classify all unicritical polynomials defined over...
Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...
Oregon State University swine herd records of 456
litters farrowed between 1962-73 in three populations were
analyzed on a generation basis to compare changes in
performance of a Composite population to parental
Berkshire and Yorkshire breeds. Analysis was performed in
six discrete and overlapping generations on backfat
thickness, loin eye...
A review of Single-Input Single-Output Internal Model Control
(IMC) is presented, showing its relationships to the Dahlin
algorithm, PID type controllers for simple models with and without
deadtime and Smith predictor control.
The effect of errors in the time constant and the gain of a
first order model with deadtime...
Biodiversity loss in highly diverse systems such as coral reefs has been linked to significant declines in the ecosystem functions and services provided by marine species. Ecological functioning of coral reefs and the resistance of coral reef fish communities to disturbance depend on the functional traits of species that promotes...
