A photometric method for the determination of proline.
The characteristic red color produced when proline interacts with ninhydrin in acidic solutions has recently been proposed for use in the quantitative assay of this imino acid (1,Z). These methods could not, however, be applied directly to the estimation of proline in biological fluids, since other amino acids interfere to some extent and must be removed either by chromatography (1) or by destr...
متن کاملA New Photometric Method for the Determination of Iron
In the study of many types of biological material it has become of increasing importance to determine accurately extremely small amounts of iron. Since color reactions are, as a rule, very sensitive, calorimetric procedures are particularly useful in the microanalytical field, and several calorimetric methods have appeared in the literature on iron determination. Although the extremely sensitiv...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Photometric Determination of Estrogens
The Kober color test for the identification of natural estrogens (1) is a 2-phase reaction. The first effect of heating estrogens with the phenolsulfonic acid reagent is the production of a yellowish brown-colored solution; when this solution is chilled, carefully diluted with water, and then reheated, its color gives way to a characteristic pink. The Z-phase nature of the reaction renders its ...
