Suppose A, B, C, D, E, F are points and L is a line other than the line at infinity. This work examines cases in which a translation D′E′F ′ of DEF in the direction of L is perspective to ABC, in the sense that the lines AD′, BE′, CF ′ concur.

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...

The ABC systems are a particular family of Lotka{Volterra systems in dimension 3. Their integrability has been studied these last years by many authors. In this paper we study the ABC systems which are algebraically integrable, i.e. the ABC systems having two independent algebraic rst integrals. For doing this we need to summarize all the known results about the polynomial and rational rst inte...
