Introduction: Sequential batch reactor (SBR) is one of the modified biological treatment systems which is able to remove BOD5, Nitrogen, and phosphorus from wastewater. The object of this study is to determine the removal efficiency of nitrogen, phosphorus, and heavy metals from municipal wastewater by the advanced SBR system. Materials and Methods: This descriptive-analytical and cross-sectio...
The processes of melt formation were studied by methods optical and electron scanning microscopy. These occur during induction brazing a hard alloy to steel holder contact interaction low-melting (copper-zinc system alloy) refractory (iron-nickel) components the solders. It is shown that effect thermal magnetic-dynamic high-frequency electromagnetic field on composite solder how high-strength j...
The long-term effects of orthodontic appliances in the oral environment and the subsequent leaching of metals are relatively unknown. A method for determining the effects of various types of soldering and welding, both of which in turn could lead to leaching of metal ions, on the growth of osteoblasts, fibroblasts, and oral keratinocytes in vitro, is proposed. The effects of cell behaviour of m...
The results of an atomic force microscopy study the surface nickel coating doped with phosphorus 2 μm thick obtained by cathodic arc evaporation after annealing at temperatures from 100 to 500 °C are presented. morphology changes significantly increase in temperature. A negative high correlation between specific energy and roughness was established. mechanical properties (microhardness, elastic...
