Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
A special case of a parallel multiprocessor scheduling (MP) problem
is investigated. A set of jobs with a known process time and a.resource
requirement is scheduled on machines controlled by processors,and
the total changeover cost between jobs is to be minimized. Each processor
may control up to two machines and...
The main objective of this thesis is to investigate the microprocessor's
potentials to improve the productivity of Industrial
Engineers engaged in work design and measurement. More exactly, the
following four hypotheses were proposed and investigated:
(1) A Universal Time Data (UTD) structure could be used to
accommodate a variety of...
Erythrocytic inclusion body syndrome (EIBS), a viral disease
of salmon, was investigated. Reliable artificial infections were
established in coho salmon (Oncorhynchus kisutch) via
intraperitoneal injection of homogenized kidney, spleen, and blood
from naturally infected animals. By examining the exposed fish
periodically for viral inclusion bodies and hematocrits, the disease
progression...
Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...
A new method is developed for solving linear optimization
problems based on the RPM network modeling technique which represents
the primal and the corresponding dual models simultaneously
upon a single graph. The network structure is used to eliminate
the need for explicit logical variables and to provide a graphic
tool...
Interspecific hybridizations between P. vulgaris and P. acutifolius
and between P. vulgaris and P. lunatus were investigated. Prefertilization
events were similar in inter- and intra-specific crosses. Fertilization
was completed in all crosses and the time of fertilization was
dependent on the maternal parent, reflecting differences in the time of
maturation...
