Study on printing wastewater treatment by decomposition reaction H2O2 catalyzed of complex between ion Ni2+ and citric acid

lexical decomposition awareness and its effect on delayed receptive and productive recognition and recall of vocabulary knowledge of morphologically complex english words: an iranian efl context

abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...

The Decomposition of Citric Acid by Bacillus Aertrycke

Decomposition of Anionic Sodium Dodecylnemzene Sulfonate by UV/TiO2 and UV/H2O2 Processes a- Comparison of Reaction Rates

Anionic DBS surfactant can be photodegraded in a TiO2 dispersion and H2O2 solution under an Hg-lamp (15 W) UV illumination or solar exposure. Degradation process has been monitored through cleavage of aromatic moiety. Degradation of the detergent was small when the photolysis was carried out in the absence of TiO2 and H2O2 an...

Naval derusting wastewater containing high concentration of iron, treated in UV photo-Fenton-like oxidation.

The UV photooxidation with Fe(III) and H2O2 was employed to treat a naval derusting wastewater, which contains the high COD (chemical oxygen demand) and various metal concentrations exceptionally with high concentrations of citric acid and iron. Because of its iron containment, the Fenton-like reaction automatically took place with the added amount of H2O2. The decomposition rate was found in a...

on translation of phatic communion and socio-cultural relationships between the characters of the novels

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
