A study on measuring the quality of university website

During the past few years, many organizations try to provide some of their services through their websites. This would help them provide fast and reliable services to various people around the world. In this paper, we present an empirical survey to measure the relative performance of a university website in Iran using Parasuraman's technological readiness index. The proposed study uses a standard questionnaire and distributes it among 387 active website users and the results are analyzed using structural equation modeling. The proposed study of this paper considers the effects of four factors including efficiency, accessibility, achievement and security on customer loyalty via two variables of trust and satisfaction. The results demonstrate that three components of trust, efficiency and achievement play essential role on customer loyalty

Optimization of nitrogen and phosphorus removal from meat processing wastewaters using microalgal biofilms

Background: The conventional activated sludge processes are not able to completely treat the nitrogen and phosphorus compounds of meat processing wastewaters. Microalgal biofilm, which has the advantages of easiness and inexpensiveness, can be applied as a post-treatment method. Methods: The optimal levels of micronutrients and N/P ratio were aimed in the cultivation of Scenedesmus quadricauda as a biofilm formed on the two types of commercially available bed packing.For this purpose, the Factorial design was run to maximize the removal of ammonium, nitrate and phosphate concentration in the synthetic meat processing wastewater. Results: Experimental data showed better results for the removal of biofilm formed on the sponge filter. In addition, a maximum removal efficiency of 55.6%, 47% and 48.% was respectively achieved for ammonium, nitrate and phosphate at optimal N/P ratio of 10.5 and volumetric percentage of 50% of micronutrients. Conclusion: The results demonstrated that microalgal biofilm of Scenedesmus is able to remove the nutritional components of meat processing wastewaters. The process is needed to be optimized for the effective treatment. Keywords: Meat, Biofilms, Microalgae, Wastewater, Scenedesmu
