This can be inserted in equation (02.2.3) to give tlie orientational distribution function, and tlius into equation (02.2.6) to deteniiine the orientational order parameters. These are deteniiined self-consistently by variation of tlie interaction strength iin equation (c2.2.7). As pointed out by de Gemies and Frost [20] it is possible to obtain tlie Maier-Saupe potential from a simple variational, maximum entropy metliod based on tlie lowest-order anisotropic distribution function consistent witli a nematic phase.

Dry Ice should be handled with gloves or with a dry towel if Dry Ice is held for a long time in the hand, it may cause frost bite. 

Sodamide. Assemble the apparatus shown in Fig. VI, 16, 1, a. Fill the bath to a point about half-way up the side of the flask with methyl alcohol (or methylated spirit) and add solid carbon dioxide (Dry Ice or Drikold) in lump form until a white frost commences to form on the outside of the bath (2) the bath temperature should be about — 35 .

For qualitative purposes the circle itself isn t even necessary We could locate the Huckel MOs by simply working with the polygons themselves The circle is needed only when Frost s method is used quantitatively In those cases the radius of the circle has a prescribed value allowing each MO to be assigned a specific energy...

Vineyard site is important to wine quaUty and character and interacts with variety. The general climate must not be too cold, too hot, or too humid. A mild, dry climate that still induces a dormant season, like the Mediterranean area and California, is desirable. A relatively constant weather pattern year-to-year is also sought. The nearer to the limits of cold tolerance, for example, that the climate comes, the more likely are disastrous vintages. The modifying influence of close bodies of water, sun-facing slopes, or frost-resisting air drainage can make one vineyard more desirable than another nearby. 

The deleterious effect of some fat substitutes has been demonstrated in cake frosting (27) the result is an unacceptable frosting, filled with air bubbles. In another example, some low fat cheeses are quite acceptable when cold, but when heated result in a product texture that changes to a sticky, gummy mass. Attempts to replace fat must be viewed as a total systems approach (28,29). It is likely that no one material will replace fats in food rather, replacement will consist of mixtures with each ingredient addressing one or more of the roles played by fats in food. 

Activity in the cereal field includes the introduction of a fiiU line of fat-free, cholesterol-free loaf cakes (23), cmnch cakes, and cookies (40) a light frosting mix and alight pancake mix are also included (41).
