Introduction At any particular wavelength the absorption of light when visible light passes through a solution depends on two factors: * The length of the light path * The concentration of the colored path The connection of these two variables is known as the Beer-Lambert Law: Absorbance (A) = ε c l Where ε is the absorption coefficient C is the concentration of the compound And l is the length of light usually 1cm When I is constant‚ this proves a linear relationship between

Dissolution[edit] In the most common situation‚ a tablet is ingested and passes through the esophagus to the stomach. The rate of dissolution is a key target for controlling the duration of a drug’s effect‚ and as such‚ several dosage forms that contain the same active ingredient may be available‚ differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved‚ the drug may be released more gradually over time with a longer duration of action. Having a

06/11 Water Absorption ASTM C 140 Water Absorption One of the most important properties of a good quality concrete is low permeability‚ especially one resistant to freezing and thawing. A concrete with low permeability resists ingress of water and is not as susceptible to freezing and thawing. Water enters pores in the cement paste and even in the aggregate. Absorption For concrete pavers‚ the test procedure involves drying a specimen to a constant weight‚ weighing it‚ immersing it in water for

The Last Leaf To be perfect short story neatness‚ brevity and a significant incident or an aspect of character or an experience of some psychological moment is essential. Within its short frame work‚ it must have a beginning‚ middle and an end. There must be completeness in its structure. All the elements plot‚ character‚ dialogue‚ descriptions and background must be organically connected with other. Generally a good story has a surprising end which bears a sense of endlessness. All these characteristics

THE LAST LEAF SCENE ONE NARRATOR: In New York City‚ there’s a small district just west of Washington Square‚ where the narrow‚ irregular streets have run crazy and broken themselves into short strips called places. It’s an ancient‚ residential community where many of the beautiful‚ old‚ brick houses date back to the 1820’s‚ when an epidemic forced people from the city to what was then a rural suburban village. Now‚ in the final year of the nineteenth century‚ we find clusters of colorful restaurants

INTRODUCTION: The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. Radiation can be said to be energy that travels and spread as it goes. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. We tend to witness different radiations of the electromagnetic spectrum without knowing‚ example is the visible light that
