The treated and untreated effluents samples from semiconductor industry were collected and thier physical characteristics such as temperature, pH, turbidity, total suspended solid (TSS), conductivity and chemical characteristics such as salinity, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), chlorine dioxide, and heavy metal were analyzed. The results obta...

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...

Most of the molecular graphs in area mathematical chemistry are irregular. Therefore, irregularity measure is a crucial parameter chemical graph theory. One such that has recently been proposed ve-degree index (irrve). Quantitative structure property relationship (QSPR) analysis explores capability an to model numerous properties molecules. We investigate usefulness irrve predicting different p...

The aim of this study was to determine the chemical composition physico-chemical properties, fatty acid and tocopherol compositions and total phenolic compounds and evaluate the radical-scavenging activity of crude oil extracted from passion fruit (Passiflora edulis f. flavicarpa) seeds, aiming to use the agro-industrial by-products. The oil seed extraction was performed by Soxhlet method and t...
