Abstract Domestic wastewater is the largest producer of in Indonesia which comes from remnants household activities. Hazardous substances such as Biological Oxygen Demand (BOD), Chemical (COD), Total Suspended Solid (TSS), Oil and Fat contained can cause health problems for humans. In this study, domestic waste treatment was carried out using Multi Soil Layering (MSL) method. The MSL system a m...

In this note we deene a layering intended to structure the many concepts which arise in the development of an Engineering Information System. The industrial beneets to be gained by such a layering are enumerated. An Engineering Information System (EIS) is a collection of facilities and services that provide support for the design, testing, manufacture, and maintenance of engineering artifacts, ...

We review various simplified models that have been advanced to describe layering (complexion) transitions at grain boundaries in multicomponent solids. In particular, we first outline lattice-gas, off-lattice atomistic and thermodynamic models that have been employed to investigate phase-like behavior at segregated grain boundaries. The results of these investigations are summarized in the form...

The classical definition of Steiner symmetrizations functions are defined according to the function level sets and layered representation functions. In this paper, is not only transformed into one-dimensional parabolic functions, but also depends on log-concave To end we prove Steiner’s inequality layering in space
