low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. it was thought that the hplc is the best method of the determination of organic acids in the apple juice. in this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extr...

separation of polycyclic aromatic hydrocarbons was performed by rp-hplc using mixed micellar mobile phase. effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (v/v) as co-organic solvent in mobile phase at 40°c. analysis of t...

This research investigates learning motivation of young and old adults. In detail, we explore motives of young and old adults to participate in two ICT-course settings: e-learning and face-to-face courses. In a first study young (n = 53, M = 26.0 years) and old (n = 55, M = 69.8 years) participants of e-learning courses completed an online questionnaire on learning motivation and personality. I...
