Trace element solubility and availability in land-applied residuals is governed by fundamental chemical reactions between metal constituents, soil, and residual components. Iron, aluminum, and manganese oxides; organic matter; and phosphates, carbonates, and sulfides are important sinks for trace elements in soil-residual systems. The pH of the soil-residual system is often the most important c...

This paper proposed an image enhancement and segmentation algorithm to localize the segment of interest in a series of images obtained from the Electron Microprobe. There are totally four different images that are corresponding to the spatial density distributions of four major chemical elements inside a meteorite rock surface. The density distribution of each chemical element is shown in a gra...

The evidence that the band gap of Si changes significantly with strain suggests that by alternating regions of strained and unstrained Si one creates a single-element electronic heterojunction superlattice (SL), with the carrier confinement defined by strain rather than by the chemical differences in conventional compositional SLs. Using first-principles calculations, we map out the electronic ...

Simulation of natural phenomena, such as temperature and air flow distribution inside a room, evolution of material damage due to mechanical and chemical loads, are crucial in the daily life of engineers. This paper presents the Computational Phenomenon Pattern, whose objective is to standardize through computational abstraction the complex interactions of coupled natural phenomena in the conte...

In the framework of Finite Element discretizations we introduce a fully nonlinear Newtonlike method and a linearized second order approach in time applied to certain partial differential equations for chemotactic processes incorporating two entities, a chemical agent and the reacting population of certain biological organisms/species. We investigate the bene t of a corresponding monolithic appr...
