During the separation itself some trouble can occur concerning the back pressure. An increasing back pressure indicates contamination of the column and thus should be monitored. If this happens or if a visible contamination of the sorbent is noticed, a regeneration of the column is necessary. However, if the back pressure rises very rapidly the column may be clogged by denatured proteins. As a first attempt, the frits should be replaced by new ones, trying the top adapter first. 

Analytical. It can be titrated with std base to a salmon colored phenolphthalein endpoint and can be quanty pptd from aq solns with tetraphenylarsonium chloride KSp of the complex in w is 6.9 x 10 9 (Ref 22). This procedure can be adapted to the analysis of compds, such as bis-(trinitroethyl) urea, which regenerate... 

The reaction is sustained by addition of iron metal which reacts with the sulfuric acid formed, regenerating Fe(n) in solution. To ensure that the desired crystal form precipitates, a seed of a-FeO(OH) is added. However, with appropriate choice of conditions, for example of pH and temperature and by ensuring the presence of appropriate nucleating particles, the precipitation process may be adapted to prepare either the orange-brown y-FeO(OH), the red a-Fe203 or the black Fe304. 

Fig. 16. Phototropic threshold of wild type and hypothetical photoreceptor mutants. Solid line = wild type large dashes = mutant with reduced number of photoreceptor dotted line = mutant with reduced absorption cross-section small dashes = mutant with slow regeneration. The changes of threshold of the hypothetical mutants were chosen arbitrarily. The figure was adapted to Fig. 6 and the solid line of the wild type represent data of Foster and Lipson (1973)...

For the discrete bubble model described in Section V.C, future work will be focused on implementation of closure equations in the force balance, like empirical relations for bubble-rise velocities and the interaction between bubbles. Clearly, a more refined model for the bubble-bubble interaction, including coalescence and breakup, is required along with a more realistic description of the rheology of fluidized suspensions. Finally, the adapted model should be augmented with a thermal energy balance, and associated closures for the thermophysical properties, to study heat transport in large-scale fluidized beds, such as FCC-regenerators and PE and PP gas-phase polymerization reactors. 

The last of these systems has been adapted to a solid-phase reagent system (Equation 4.9) that obviates the problems associated with byproduct removal, and the by-product may be recycled (treatment with phosgene) to regenerate the active insoluble reagent.1819... 

GO-flning [Gas-oil refining] A hydrodesulfurization process adapted for gas oil. The proprietary catalyst is regenerable. Developed by Esso Research Engineering Company and the Union Oil Company of California and jointly licensed by them. First commercialized at Wakayama, Japan, in 1968 by 1972, nine units had been built. 

Agrobacterium-mQdi iQd DNA transfer technique and direct gene transfer into protoplasts on the basis of the electroporation technique have frequently been used for the gene transfer methods in plants. However, these methods were hardly adapted to monocotyledonous plants or to varieties in which regeneration system was not established. These deficiencies found in gene transfer techniques will be largely overcome if pollen could be used as a DNA vector. 

The problem of calculating the degree of orientation and size from a scattering pattern has been widely addressed in the scientific literature [86, 88]. In the study of regenerated tissues a two-dimensional analog of the Hermans orientation index [89, 90], previously used to specify the orientation of a polymer from X-ray scattering data, was adapted [81, 91].
