Therefore, an important and unresolved part of the problem of improving compression foam generating units is the development of a mathematical apparatus describing their operation. 3 Presentation of Basic Material It is known that there are two hypotheses for the propagation of sound in the air: isothermal and adiabatic, and that, as a result of numerous experiments with the speed of sound in a gas environment, it is proved that it is an adiabatic process and that the speed of processes during the propagation of an acoustic wave causes the heat to not reach to neighboring gas parts [17].

The reason behind the grinding aid’s decreasing the hardness is based on Griffith’s theory regarding fragile breakage, which postulates that fragile materials contain small cracks whose propagation may lead to material breakage The Rebinder effect [10-11] concept that a compound capable of selective adsorption inside the solid particle cracks undergoing grinding would impede the attraction between any residual electric forces, and in so doing it may impede any crack closure during the inactive phase.
All concepts suggested for the mechanism of the grinding aids depend mainly on the material undergoing grinding since they get adsorbed on the respective material.
Materials and Methods 2.1 Raw materials Grinding aids: monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA), are analytical reagent.

Materials and Methods The problem under study includes specific number of mixed-model assembly lines in a shop floor environment where different types of jobs can be processed and each line consist of manual workstations in which each assembly station capable of serving any task of any jobs.
Three objectives are considered in this problem which as follows: Ÿ Minimizing overall make-span Ÿ Line balancing Ÿ Minimizing variation of completion time A workstation in any line should be setup for the new materials requirement to be able to serve the new set of products.

Product life-cycle includes providing raw materials, design and production, marketing, use and conservation, and recycling [1].
Integrated management theory has two basic views [5]: First, the process view, by which subjects of integrated management have clear objectives of the integration, various integration elements (people, machines, financial, material, information, organizations, etc.) are integrated objects, integration activities is a system activity, integrated management is an ongoing dynamic process of adjustment; Second, the technical view, by which the essence of integrated management is to manage integrated activities to promote integration of knowledge production, dissemination and application, that is, integration management itself is a kind of technology.
