Gelatine Subject

W e know of many examples of the effect of impurities of crystallization. In many cases impurities will completely inhibit (2-4) nucleus formation. Reading the literature on this subject impresses one with the frequent occurrence of hydrocolloids as crystal modifiers, particularly where sugar or water is the material being crystallized. The use of gelatin, locust bean gum, or sodium alginate in ice cream is just one example of many practical applications of hydrocolloids in crystal modification. 

The flow-through cell is applicable not only for the determination of the dissolution rate of tablets and sugar-coated tablets, but has also been applied to suppositories, soft-gelatin capsules, semisolids, powders, granules, and implants. A small volume cell containing the sample solution is subjected to a continuous stream of dissolution media. The dissolution...

The chapter on the formulation of proteins has been expanded but the contents will reflect my own personal scientific interests, and the current literature will, inevitably, contain additional information on different approaches to the subject. Two additional chapters are included since some proteins, such as albumin or gelatin, can serve as drug delivery systems in their own right. In addition, proteins and phospholipids undergo characteristic interactions and deserve closer and separate attention. 

Flake or tubular rifle powder should be subjected to surface gelatinization and coating with graphite. This is usually called polishing and constitutes the most delicate operation in the manufacture of rifle powder (for calibres from 7.6-20 mm).
