This paper attempts to predict heavy metals (Pb, Zn and Cu) in the groundwater from Arak city, using support vector regression model(SVR) by taking major elements (HCO3, SO4) in the groundwater from Arak city. 150 data samples and several models were trained and tested using collected data to determine the optimum model in which each model involved two inputs and three outputs. This SVR model f...

measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...

the present study investigated no3- and br- contamination in groundwater of arak aquifer of markazi province. correlation and factor analysis were used to detect interrelation and sources of concentration of no3- and br- ions and others physicochemical variables. no correlation was observed between no3- and others contents, but positive correlation was identified between br- with other major va...

Background: Soil structure is mainly composed of sand, silt, clay, and organic materials. Organisms can live in the soil. The large number of stray cats in the cities of Iran is a major environmental and health problem. Toxoplasma oocysts are shed with the feces of cats, so soil is known as a potential source of transmission of toxoplasmosis. The aim of this study was to determine the soil cont...

BACKGROUND Bioflavonoids are well known for their multi directional biologic activity including antidiabetic effect. It has been demonstrated that flavonoids can act as insulin secretagogue or insulin mimetic agents. OBJECTIVES This experimental study was designed in Arak University of Medical Sciences, Arak, Iran, to investigate the effects of biochanin A (a bioflavonoid) on fasting blood gl...
