Greywater is the most sustainable option to address growing need for fresh water. This study aimed identify optimal operation variables of an electro-coagulation filtration (ECF) system treating domestic greywater, using different conditions (e.g., electrode combinations (Al-Fe-Al-Fe), initial pH (6.8–8.4), operating time (10–60 min), and voltage (6–24 volts)). A statistical data analysis was p...

Generally, the equivalent conicity function (ECF) is denoted by at 3mm (?3mm) and a Nonlinearity Parameter (NP). NP describes nonlinearity of ECF its influence on vehicle design explored thoroughly, however, NP’s role in track maintenance not researched yet. This paper investigates actions dynamics with help vs ?3mm scatter plots database. The database constructed combining measured worn wheel ...

Enterocutaneous fistulas (ECFs) are great challenges during the open abdomen. The loss of digestive juice, water-electrolyte imbalance and malnutrition are intractable issues during management of ECF. Techniques such as "fistula patch" and vacuum-assisted closure therapy have been applied to prevent contamination of open abdominal wounds by intestinal fistula drainage. However, failures are enc...

We describe a perturbation formulation for the problem of computing electrostatic capacitances of multiple conductors embedded in multiple dielectric materials. Unlike the commonly used equivalent-charge formulation (ECF), this new approach insures that the capacitances are computed accurately even when the permittivity ratios of the dielectric materials are very large. Computational results fr...

One of the foremost functional attributes of the mammalian kidney in health is its ability to regulate the excretion of sodium with sufficient precision to allow for the maintenance of a constant content of sodium in the extracellular fluid (ECF). In essence, whatever quantity of sodium enters the ECF from dietary intake must be excreted by the kidney, and this commitment must be upheld regardl...
