Lines, sketching

Room overpressure can conveniently be tested during this period. Produce a single line sketch of the conditioned space(s) including doorways. Test for air-flow direction with hand smoke tubes, both at the top and bottom of closed doors, and record the direction of flow. Crack the doors open if fully sealed. 

The general qualitative agreement with experiment provides support for the theory that the potential barriers to internal rotation result from the interaction of adjacent hybrid bond orbitals with a small amount of / character. The magnitude of the potential barriers, about 4 per cent of the energy of the axial bond in case that there are three interacting bonds on each of the two atoms and proportionately less for a smaller number of bonds, is also reasonable. A detailed quantum-mechanical treatment of restricted rotation carried out along the lines sketched here should yield results that would permit a detailed test of the theory to be made in the meantime I believe that the above simple treatment and the extensive empirical support of the theory provide justification for it. 

While a full quantitative analysis along the line sketched has not yet been performed for data like those of Fig. 21, there are a few semiquantitative conclusions that are worth noting ... 

The line-sketch of a simple flame photometer is shown in Figure 25.2.

In the following Chaps. 24-27 the most important process and product properties will be discussed along the lines sketched in Chap. 3. 

Figure 16 Photothermal deflection spectrum of a NH3 -compensated trans-VA. Dots and dashed line show the absorption edge recorded on two films, 4 p.m and 0.1 xm, respectively. Dotted line shows the residual absorption of an uncompensated sample. Solid line sketches the expected neutral soliton absorption in the absence of electron correlation. (From Ref. 130.)...

Figure 6. The abundance ratio [Y/Ba] versus [Fe/H] for metal-poor giants and dwarfs. Plotted data are tkaen from a variety of sources - please see Lambert Allende Prieto (2002) for the key to the symbols. The solid lines sketch possible boundaries to the data.

(45 7)) pressure dependences (lower drawings) of the shear viscosity 7] at various temperatures (adapted from Ref. (48)) and of the isothermal diffusion coefficient Z) at 0 (adapted from Ref. (49)). Dashed lines sketch typical dependences displayed by almost all other liquids. Note that at —15 °C no value is given for 17 at/ > 300MPa, because of a phase transition towards ice V (Figure 8.5).

Fig. 6. Schematic of IQNS and NMR studies of MHS compounds. From left to right schematic of the close environment of the HS- anion. The EISF shows that the orientation occurs within height sites in the HTP and two sites in the MTP. The correlation time is discontinuous at the transition. Schematic variation of the proton spin-lattice relaxation. The thick lines sketch data and thin lines fits.

First derive an expression for C qi as a function of C u and 0. Sketch the conversion and temperature profiles for the case vvhe inerts are present. Using a dashed line, sketch the profiles when a erate amount of inerts are added. Using a dotted line, sketch the pn when a large amount of inerts are added. Sketch or plot the exit co siun as a function of 0,. Qualitative sketches are fine. 

Cloud-point curves of quasi-binaiy solutions often exhibit a dent as seen in the data of Rehage et al. (see also curve 4 in Figure 9-1), and the critical point is usually located somewhere in the dent. In some cases, the dent has a break, as sketched in Figure 9-13 (actual examples are seen, for instance, in Koningsveld s data [33] on the system polyethylene + diphenyl ether). When this happens the critical point either appears very close to the break point or disappears in the immiscibility region below the observable cloud-point curve. In the latter case, the cloud-point curve has an invisible loop with cusps as shown by the dashed line sketched in Figure 9-43. 

Learning to sketch objects starts with learning to sketch lines. Sketch very lightly. This will cut down on the need to erase and save time. Once you have completed your sketch, you can trace the lines you want to keep so they will be darker and stand out (see Figure 4-18).

The calculations underlying Fig. 51 are not based on Eq. (212) but on a slightly more elaborate equation, involving contributions of the B state as well as Franck-Condon effects due to other modes, represented by a displaced oscillator, along the lines sketched in Section VIII. These added details are needed to secure good agreement with the experimental data but do not affect the general behavior of the dispersion curves. 

Sketch the energy diagram for an endothermic reaction using a solid line. Sketch what would happen to the energy profile if a catal) t is added to the reaction using a dotted line.

What has been sketched here is obviously just the bare framework of a general investigation of the symmetry properties of momentum space functions in quasicrystals. With all the information available in the papers by Mermin and collaborators it should however be a very tempting enterprise to go ahead along the lines sketched and learn about the details of the symmetry properties of those wave functions - both in momentum and in positition space - which will be needed in quasiperiodic extended systems. 

Like any angular momentum, spin angular momentum can be coupled to another spin angular momentum along the lines sketched in the last section. Two single spin operators couple to a total spin operator S via... 

It appears that problems which have been solved along these lines are manifold Melting and solidification of alloys in metal casting, the occurrence of "mushy regions in (binary) systems of compositions deviating from the eutectic composition etc. See e.g. the beautiful book by John Crank (5), where only occasionally an exception is made from the lines sketched so far in the introduction. 

Crud Chemicals is producing a copolymer of Fj = 0.5 in a CSTR (Figure 11.4b). For their system, Vi = 2.0, V2 = 0.5. Things are going along fine until the feed pump for monomer 1 suddenly quits. It takes the maintenance people a couple of hours to get it back on line. Sketch qualitatively F/ and (F/) versus time for the period from immediately before the breakdown to the restoration of steady-state operation (well after the repair). 

Consider a piping system with a 90° elbow in the horizontal plane. The elbow is fitted with two flush pressure transducers, one at the inside and the other at the outside on the 45° line.
