The mechanisms by which nucleophilic substitution takes place have been the subject of much study Extensive research by Sir Christopher Ingold and Edward D Hughes and their associates at University College London during the 1930s emphasized kinetic and stereochemical measurements to probe the mechanisms of these reactions... 

For banks of in-line tubes,/for isothermal flow is obtained from Fig. 6-43. Average deviation from available data is on the order of 15 percent. For tube spacings greater than 3D(, the charts of Gram, Mackey, and Monroe (Trans. ASME, 80, 25—35 [1958]) can be used. As an approximation, the pressure drop can be taken as 0.32 velocity head (based on V ) per row of tubes (Lapple, et al.. Fluid and Paiiicle Mechanics, University of Delaware, Newark, 1954).

On the basis of this work and other research, in 1849 Helmholtz was appointed professor of physiology at the University of Koonigsberg. There he devoted himself to the physiology of the eye, first explaining the mechanism of lens accommodation. In 1851 Ins invention of the ophthalmoscope, still the basic instrument used by eye doctors to peer at the retina of the eye, immediately made Helmholtz famous. In 1852 he also became the first experimentalist to measure the speed of nerve impulses in the human body.

These design guidelines, though not universally agreed upon by every FCC expert, can be useful to the refiner in ensuring that the mechanical upgrade of a unit will be safe, reliable, and profitable. 

It is not surprising that hardness is important because the mechanical toughness can be expected to decrease with increasing hardness, and the level of residual stress present will also depend on the hardness of the steel, especially for welded components. Thus, the important role of the microstructure in influencing susceptibility to stress-corrosion cracking is consistent with the observation that hardness levels are a good guide to stress-corrosion resistance, but they should not be used universally without due consideration of the specific alloy and the environment in which it is to be used.
