Choice of host

Choice of host plant the plant is not widely cultivated in the area where the transgenic plants are grown, it has no wild relatives with which to cross and it is preferentially self-pollinating. 

The choice of host plants is affected by a vast array of positive and negative factors. These opposing forces generally fall into one of the categories listed below ... 

Fortunately, in some rare instances, by an appropriate choice of host, excitation wavelength, temperature, and doping level, certain processes can be made to predominate. By this means, one attempts to make a step-by-step study of the various mechanisms. 

We have already stated that proper choice of host and activator is essential to obtain an efficient phosphor. Now consider the case where one-hundred (100) photons are incident upon the phosphor. From our discussion given above, we know that a few are reflected, some are transmitted, and, if the phosphor is an efflclent combination of host and activator, most of the quanta are absorbed. But not all the absorbed quanta will result in an activated center, and, once these centers become activated, not aU will emit a subsequent photon. Some become deactivated via relaxation processes. To determine just how efficient a phosphor may be, we measure what is termed the "quantum efficiency", i.e.- QE. The quantum efficiency is defined as ... 

After considerable work, it was determined that the hosts which work best in this application are those in which vlbronic coupling is minimized. This was established by determining and comparing the phonon dispersion branches of the various compounds. It was found that those hosts which have low energy optical branches in the phonon spectrum function best for up-conversion phosphor applications. Note that this is akin to minimizing ground state perturbation at the activator site proper choice of host. The best hosts were found to be ... 

It is a characteristic of the rhizobium-legume symbiosis that the bacteria exhibit great specificity in their choice of host, indeed the genus Rhizobium is divided into species on the ability of the strain to form nodules in specific plant species (Table 6.1). Inter-species and inter-strain nodulation may occur, although often the nodules produced are atypical and fail to fix nitrogen effectively. 

The Simulation Form (Fig. 9) displayed by a left mouse click on the Simulation Node (entitled Mo Simulation or C Radical in Fig. 9) in the Explorer Tree allows the choice of Host on which to execute the computational program Sophe (currently only localhost), the process priority, whether to run it interactively or in a batch queue (currently only interactively), and the host running the XeprView ...
