Seven diets were constructed from purified natural ingredients obtained from either C3 (beet sugar, rice starch, cottonseed oil, wood cellulose, Australian Cohuna brand casein, soy protein or wheat gluten for protein) or C4 foodwebs (cane sugar, corn starch, com oil, processed corn bran for fiber, Kenya casein for protein) supplemented with appropriate amounts of vitamins and minerals (Ambrose and Norr 1993 Table 3a). The amino acid compositions of wheat gluten and soy protein differ significantly from that of casein (Ambrose and Norr 1993).

Genetic modification of many dicotyledoneous crops such as potato using gene transfer via A. tumefaciens is, at present, an efficient and reliable technique the application of the antisense route to limit or neutralize the action of undesirable genes has also been applied successfully to potatoes. Conversely, for monocotyledoneous crops such as maize, wheat, and rice, transformation can be accomplished by the much less efficient particle gun technique. This technique has been improved, resulting in rapid progress in the development of maize and later wheat with improved agronomic properties and/or altered starch composition. 

There are two ways to hold the composition of Senko-Hanabi one is a dry process twisting a piece of Japanese paper tape 23 mm wide and 200 mm long containing about 0.09 of the composition at one end the other is a wet process where sticks made of rush or straw are dipped into a liquid mixture to a desired depth, withdrawn and dried in the sun. The liquid mixture is made by adding glutinous rice starch and water to the composition. 

The symbol OO in Table 13 shows the composition did not decompose when heated for a long time. It must be noted that wet aluminium powder decomposes without other chemicals when it is heated for a long time. Glutinous rice starch does not react with aluminium. 

This cohesive nature of glutinous rice starch is quite important especially for preparing round stars, because the essential point of the process lies in that the composition must be pasted in a wet state on the core using as little paste as possible Accordingly a paste which has a strong cohesive power satisfies the requirement well. For this reason glutinous rice starch is quite superior for manufacturing round stars. 

However the cohesive power of the paste of glutinous rice starch generally changes as the time passes when it is mixed with chemicals or compositions. For example, an experiment in the summer season is set out in Table 16. 

The decrease in the viscosity caused by sodium oxalate or black powder, which are the most powerful, was more precisely observed. In the first one or two hours it looks as though there is an increase in the viscosity, and then the viscosity slowly decreases after five or six hours the viscosity is not so different as that at the beginning. This property of glutinous rice starch does not cause any trouble in manufacturing stars, but the paste of a composition which contains glutinous rice starch must not be left more than half a day. 

Fig,56 and 57 shows the influence of glutinous rice starch upon a chlorate composition and a perchlorate composition respectively when stars are manufactured with it as a binder. The symbols are as follows ... 

For example, a 3 nim cubic cut starofthe chlorate composition containing k% glutinous rice starch is denoted by a point P in Fig,56 (the half thickness of the star is 1,5 mm). We know from the lines that the star is dried in 1,5 hours in a warm-air drier at 50°C or in 22 hours in a room at normal temperature. It takes more than 5 minutes at room temperature to completely soak it with water. The hardness of the star is 12 kg if it is dried in a room at a normal temperature and 10,5 kg...

The vapourization of the solvent (including v/ater). A dough which contains glutinous rice starch and is charged into a tube, shrinks slowly as it dries and creates a gap especially if it is in a metal tube, even when the tube is less than 3 in internal diameter. During the manufacture of small pieces like igniters this is important. It is a common rule to decrease the amount of solvent in a composition as far as possible. When the composition feels to be rather wet, it contains 2 3% solvent or water. A composition like this is most unlikely to shrink, when it is formed into a mass under high pressure. 

At low temperat res in winter or in small quantities it may be possible to consolidate the compositions into stars with water and soluble glutinous rice starch. except few compositions when we use a magnesium powder which is coated with linseed oil. It is an important rule however to use a binder solution in an organic solvent for this consolidation in place of the water and glutinous rice starch, this is to avoid the danger of generating heat and hydrogen gas. Nitrocellulose solution in amyl acetate or in acetone is very convenient to use for this(s.l4.2... 

I and II use a white smoke generated from the flame. White willow uses the smoke formed by the condensation of sulphur vapour without flame. The realgar allows the composition to burn smoothly. The stars of I and II are coated by an ignition composition. The white willow is manufactured as follows Form the composition into cut stars. Dry them well. Place them in a coating tub. Add to it slurry paste of soluble glutinous rice starch and shake the tub so that all the surfaces of the...
