In this paper,the authors first introduce the concept of congruence pairs on the class of decomposable mS-algebras generalizing that for principal mS-algebras(see[13]).They show that every congruence relationθon a decomposable mS-algebra L can be uniquely determined by a congruence pair(θ_(1),θ_(2)),whereθ_(1)is a congruence on the de morgan subalgebra L^(∞)of L andθ_(2)is a lattice congruence on the sublattice D(L)of *** obtain certain congruence pairs of a decomposable mS-algebra L via central elements of ***,they characterize the permutability of congruences and the strong extensions of decomposable mS-algebras in terms of congruence pairs.

more than 170 million people worldwide have chronic hepatitis C. Acute hepatitis C is rarely diagnosed because it is commonly asymptomatic. most infected patients are unaware of their condition until the symptoms of chronic infection manifest. Treatment of acute hepatitis C is something of a paradox because spontaneous resolution is possible and many patients do not have symptoms. However, several factors provide a rationale for treating patients who have acute hepatitis C. Compared with acute hepatitis C, chronic hepatitis C is associated with a worse prognosis, the need for more intensive treatment, longer treatment duration, and a decrease in successful treatment outcomes. Conversely, early intervention is associated with improved viral eradication, using a regimen that is better tolerated, less expensive, more convenient, and of shorter duration than the currently approved combination therapies for chronic hepatitis C.
