A Preliminary Study of the Rideal-Walker Coefficient Values of Certain Indigenous Essential Oils

buckling of viscoelastic composite plates using the finite strip method

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....

A Method of Standardizing Bacterial Suspensions

The opacity of a bacterial suspension is measured by the length of the column of the suspension required to cause the disappearance of a wire loop. By a simple formula the measured opacity is translated into terms of the concentration of bacteria per cc., and so made comparable with that of other suspensions of the same organism. An instrument for measuring the opacity of bacterial suspensions ...

A new method of standardizing death rates.

Two methods of standardizing death rates for age are in common use, the "direct" and the "indirect" Both of these methods require a detailed knowledge of the age structure of the population in which the deaths occur, and the direct method requires the age structure of the deaths in addition. A third method is now suggested which requires only detailed knowledge of age structure of the deaths th...
