the influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Adsorption behavior of condensed phosphate on aluminum hydroxide.
Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...
متن کاملFerric Phosphate Hydroxide Microstructures Affect Their Magnetic Properties
Uniformly sized and shape-controlled nanoparticles are important due to their applications in catalysis, electrochemistry, ion exchange, molecular adsorption, and electronics. Several ferric phosphate hydroxide (Fe4(OH)3(PO4)3) microstructures were successfully prepared under hydrothermal conditions. Using controlled variations in the reaction conditions, such as reaction time, temperature, and...
متن کاملKinetics and Thermodynamic Study of Nitrate Adsorption on Granular Ferric Hydroxide
This study explored the feasibility of using granular ferric hydroxide as adsorbent for the removal of NO3-N. Optimum conditions for NO3-N removal were found to be pH 5.0 and equilibrium time 80min. The equilibrium sorption isotherm was better described by Langmuir sorption isotherm model. The maximum sorption capacity of granular ferric hydroxide was 4.254mg/g at 298K. A comparison of four kin...
