DNA markers that detect polymorphisms within and between two biological species of the coniferous laminated-root-rot fungus Phellinus weirii were developed and used to
measure the amount and distribution of genetic variation. In a preliminary survey, total cellular DNA from 3 Douglas-fir-type isolates and 3 cedar-type isolates was digested with 12...
Describing functions have traditionally been used to obtain the
solutions of systems of ordinary differential equations. In this
work the describing function concept has been extended to include
nonlinear, distributed parameter partial differential equations. A
three-stage solution algorithm is presented which can be applied to
any nonlinear partial differential equation....
Muitiregion annular geometry is a basic feature of energy removal
systems ranging from advanced heat exchangers to fission reactor fuel
rods. For the symmetric cases, the heat conduction through annular regions
is well defined. However, for a shift of an annular region, analysis
of the system must be made in...
Research was carried out to determine the influence of increasing
the percentage base saturation of the soil on the yield of
the commercial strawberry. It was found that the effect of increasing
the bases in the soils was directly related to the original
percentage base saturation. When this original value...
The foundation upon which any cooperative rests is the economic need for it as a business enterprise. The existence of such a need cannot by itself provide the basis for a thriving cooperative. Not only mus.t the need exist, but the members or the promoters must through realistic and diligent...
