can be achieved. One of the most direct ways by which one drug can reduce the effect of another (or of an endogenous mediator) is known as reversible competitive antagonism. Atropine is such an antagonist‚ which acts non-selectively at muscarinic receptors. Reversible competitive antagonism is a form of receptor block by which a substance selectively binds to a particular type of receptor without eliciting a response‚ in such a way that also prevents

Without knowing something about differential equations and methods of solving them‚ it is difficult to appreciate the history of this important branch of mathematics. Further‚ the development of differential equations is intimately interwoven with the general development of mathematics and cannot be separated from it. Nevertheless‚ to provide some historical perspective‚ we indicate here some of the major trends in the history of the subject‚ and identify the most prominent early contributors. Other

Mirror and Magnification Equations The mirror equation expresses the quantitative relationship between the object distance (do)‚ the image distance (di)‚ and the focal length (f). The equation is stated as follows: [pic] The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows: [pic] These two equations can be combined to yield information about the
