the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...

   In this manuscript, a solar cavity packed with thermoelectric generator modules is investigated numerically. The hot plate of TEG modules make the inner surface of the cube, and the cold plate is outside of the cavity, under natural convection. The TEG modules are electrically in series. The solution algorithm using the equations of heat transfer and generated power of TEG modules is d...

Abstract Fisher [10] and Baur [6] showed independently in the seventies that if T is a complete first-order theory extending of modules, then class models with pure embeddings stable. In [25, 2.12], it asked same true for any abstract elementary $(K, \leq _p)$ such K modules $\leq _p$ submodule relation. this paper we give some instances where true: Theorem. Assume R an associative ring unity. ...
