Introduction: this age is based on education and research, but librarians have the main role for teaching information literacy and using the references to the users. Librarians, themselves should have enough information literacy and skills in order to move information to users and give convenience information services to their users’ library. The objective of this research is the survey study o...

Background and Objectives: Ciprofloxacin is an emerging and degradable pollutant that cannot be efficiently removed by common water and wastewater treatment processes. Electro-Fenton process is one of the most effective processes for the treatment of these compounds. Hence, the present study aimed to remove ciprofloxacin by Electro-Fenton method with heterogeneous catalysts, Fe+2 and Fe+3. Mat...

The aim of this study is to determine the validity and reliability of drivers aberrant behavior questionnaire in urban Bus Company. Materials and Methods: This descriptive study was performed on 168 subjects (in order to exploratory factor analysis) and 161 subjects (for the sake of confirmatory f...

  Background and Objectives : RUNX2 is the most specific transcription factor in osteoblastic differentiation of MSCs. In this research, RUNX2 expression was quantified in MSCs differentiated by osteogenic differentiation medium (ODM) and zoledronic acid (ZA).   Materials and Methods: In this experimental study, hMSCs were treated by osteogenic differentiation medium and ZA. RNA extraction was ...

Background and Objectives: Sulfate is one of the chemical pollutants in water that can cause adverse health effects such as digestive and blood problems at high concentrations in humans. Conversion of sulfate to substances such as hydrogen sulfide can corrode metal pipes. Therefore, the aim of this study was to investigate the effect of electrochemical sulfate removal using a sandwich panel car...

Background and Objectives: Production and use of valuable compounds such as biosurfactants from wastewater, with regard to its environmental and economic benefits, is of particular interest recently. Nowadays, biosurfactants produced by microorganisms are used in various food sources, pharmaceuticals, petrochemicals, oil extraction, and wastewater treatment plants. This study was conducted to e...
