One of the nutrients that babies need is iron (Fe). Iron content can be measured by atomic absorption spectrophotometry (AAS). This method often used because it simpler, more accurate and has high precision. study was to determine levels precision examination in breast milk using AAS. The this research preparation samples, tools, materials, manufacture a standard solution (Fe), calculation valu...

Abstract We derive the thermal noise spectrum of longitudinal and transverse electric field operator a given wave vector starting from quantum-statistical definitions relate it to frequency dependent complex conductivity in homogeneous, isotropic system electromagnetic interacting charged particles frame non-relativistic QED. No additional assumptions except validity linear response are used pr...

We report on the Modeling Across the Curriculum Project (mac.concord.org), a 5-year study funded by the IERI program (IERI # 0115699). In this project we are using qualitative model-based tools for inquiry in three science domains (Genetics, Gas Laws, & Newtonian Mechanics) to promote scientific literacy on a broad scale, namely, content knowledge, process skills, and epistemologies of science ...

The aim of this study was to examine Iranian EFL university students’ level of anxiety and their perceptions towards in-class activities during speaking courses and possible causes of apprehension. Moreover, this study investigated whether or not EFL university students’ gender differences affect their perceptions of foreign language speaking anxiety. To this end, data were collecte...

Research consistently shows that groups composed of cognitively diverse individuals develop more effective approaches in solving complex problems, and generate more creative and innovative ideas relative to groups that are not cognitively diverse (Hoffman & Maier, 1961; Hong & Page, 2004; Page, 2007; Johnson, 2008). The concept of cognitive diversity is defined as the degree to which group memb...

Abstract The present study was an attempt to investigate the relationship between EFL learners’ anxiety and writing complexity. For the purpose of the study, 70 female learners, between 17 and 24 years old (mean=20) from Najm language school in Tehran participated in the study. The participants’ level of anxiety was measured using Horwitz, Horwitz, and Cope’s Anxiety Questionnaire (1986) and th...
