Generalized modal analysis techniques for the characterization and modeling of dissipationless planar waveguide structures and discontinuities encountered in microwave and optical integrated circuits, as well as of quantum waveguide structures and devices, are presented. The frequency-dependent transmission properties of the curved microstrip bend are derived by utilizing a second-order perturbation...
The production of barley (Hordeum vulgare L.) haploids by crossing with
H. bulbosum is a widely used tool in breeding and genetics. Certain barley
genotypes have low seed set in this interspecific cross, a phenomenon known
as partial incompatibility. Haploid production efficiency and gamete sampling
are important issues with the...
Black locust seedlings were raised in white ray leach super cells from seed of an unknown California source in the shade house at Oregon State University, Forest research
Laboratories. When the seedlings were 25 days old, application of 4 levels of nitrogen i.e. zero, low, medium and high (0, 100,...
