Background & Aims of the Study: We evaluated corrosion and scaling potential of water treated by “Takab city (Western Iran) water treatment plant (called Chahar Tagh facilities)” using field observation of water treatment plant, and study of physical and chemical parameter values of water. Materials & Methods: In this cross-sectional study, during a 10-month period (fro...

we have studied the medicinal plants of ghasemloo and then surveyed the usagepercentage of different parts from each specimen for the medicinal or diet consumptions atthree sites from the adjacent villages of ghasemloo valley, villages of west and eastazerbaijan including 17 questioners. during two years, the medicinal plants that have beencollected and provided as herbarium specimens were reco...

A Mach-Zehnder interferometer is employed to detect localized corrosion at the metal/solution interface in the potentiodynamic sweep of the iron electrode in solutions. During the electrochemical reactions, local variations of the electrolyte's refractive index, which correlate with the concentration of dissolved species, change the optical path length (OPL) of the object beam when the beam pas...

In [13] co graphs are introduced and a formula is given for the PI index of these graphs. Based on this formula a new topological CI index is proposed. In this note it is observed that co graphs are precisely isometric subgraphs of hypercubes alias partial cubes. Some fact about partial cubes and their uses in chemical graph theory are listed. A couple of comments on the CI index are also given...

Taking the slope of Suiyu Railway to study, the research separately studied soil resistivity, soil electrochemistry (corrosion potential, oxidization reduction potential, electric potential gradient and pH), soil anions (total soluble salt, Cl(-), SO4(2-) and ), and soil nutrition (moisture content, organic matter, total nitrogen, alkali-hydrolysable nitrogen, available phosphorus, and availabl...

background & aims of the study: corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. the aim of this study was to assess the corrosion and scaling potential of drinking water resources in babol city, iran. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calcium hardness, ph, total alkalinity...

A time–frequency analysis-based signal processing study for detecting active corrosion in aluminum plate-like structure utilizing the broadband piezoelectric wafer active sensors is presented in this article. Tests were conducted on an aluminum plate with a network of sensors installed on one side of the plate for Lamb wave generation and reception. The corrosion was emulated as material loss o...
