Figure 1.1a shows the Gaussian function. The Lorentzian shape is similar to the Gaussian, but falls off more slowly. The Doppler shift of radiation from an emitting molecule is proportional to its velocity component in the direction of observation. The one-dimensional distribution of speeds in a gas is a Gaussian function. (See any physical-chemistry text.) Hence when Doppler broadening is dominant, we get a Gaussian-shaped line. 

Figure 7.23 Bode plot of open-loop gain of OA (lines A and B), with gain-frequency shaping (lines G and H), cell attenuation (line C), and the product of H and C (line E). See the text for details.

FIGURE 13.13 The characteristic shapes (lines 1 and 3) of the time dependence of the concentration of a reactant during a second-order reaction. The lower gray lines (2 and 4) are the curves for first-order reactions with the same initial rates. Note how the concentrations for second-order reactions fall away much less rapidly at longer times than those for first-order reactions do. 

A 62-year-old man with diabetes was given metformin 750 mg bd and his blood glucose concentration fell from 22 to 15 mmol/1 within 4 days. The dose of metformin was increased to 850 mg bd and the blood glucose concentration fell to 8.7 mmol/1 over the next week. Within 2 days of starting therapy his vision became blurred. Slit lamp examination 2 weeks later showed cracked shaped lines on the lens. The cracks resolved spontaneously by 3 months. 

This is graphically represented by a broken volcano-shaped line (Fig. 20). The coordinates of the peaks of these curves are E0 = u/2, q = s/2. From the peaks straight lines extend at an angle of 45° to the axis of abscissae. Each reaction has its particular volcano-like curve, and each catalyst (as well as the group of atoms A, B, C, and D) its secant E, for example, EG, Fig. 20. It is found that the activation energy...

Bessemerising.—For this purpose basic converters are used. These are cylindrical in shape, lined with magnesite bricks, and measure 30 feet in length and 10 feet in diameter. A stack rises from the centre to enable the gases to escape, and the necessary air-blast is supplied through 44 tuyeres at the rate of 6500 cubic feet per minute, and under a pressure of 10-5 lb. 

Derive an expression in terms of T2 for the width at half-height of a Gaussian-shaped line. 

Logistic function generally yields a sigmoidally shaped line similar to that defined by drug dose-response relationships in biological systems. It is defined by y = (1 + e-(a + bx))-1. 

The chemical reaction between a solid and a reactive fluid is of interest in many areas of chemical engineering. The kinetics of the phenomenon is dependent on two factors, namely, the diffusion rate of the reactants toward the solid/fluid interface and the heterogenous reaction rate at the interface. Reactions can also take place within particles, which have accessible porosity. The behavior will depend on the relative importance of the reaction outside and inside the particle. Fractal analysis has been applied to several cases of dissolution and etching in such natural occurring caves, petroleum reservoirs, corrosion, and fractures. In these cases fractal theory has found usefulness for quantifying the shape (line or surface) with only a few parameters the fractal dimension and the cutoffs. There have been some attempts to use a fractal dimension for reactivity as a global parameter. Finally, fractal concepts have been used to aid in the interpretation of experimental results, if patterns quantitatively similar to DLA are obtained. 

A FIGURE 6-4 Principal types of epithelium. The apical and basolateral surfaces of epithelial cells exhibit distinctive characteristics, (a) Simple columnar epithelia consist of elongated cells, including mucus-secreting cells (in the lining of the stomach and cervical tract) and absorptive cells (in the lining of the small intestine), (b) Simple squamous epithelia, composed of thin cells, line the blood vessels (endothelial cells/endothelium) and many body cavities, (c) Transitional epithelia, composed of several layers of cells with different shapes, line certain cavities subject to expansion and contraction (e.g., the urinary bladder). 

With regard to the described situation we have studied the ability to guide a spiral wave along an arbitrarily shaped line detector. Fig. 9.6(b) shows the successful shift of the spiral wave from point B to A avoiding its...
