In this study effects of agricultural advisory services on input and output of sugar beet are examined by means compare and estimating the transcendental engineering production function. The empirical results based on the ...

We investigate those conditions under which a Jordan

generalized derivation on a trivial extension algebra is a general-

ized derivation. Some applications to triangular algebras are also

presented....

In this talk we present the structures of derivations

and Jordan derivations on a module extension algebra. We shall

show that under some mild conditions every Jordan derivation on

a module extension algebra is a derivation....
