the down-flow hanging sponge (dhs) reactor, which was developed for post-treatment of effluent from up-flow anaerobic sludge blanket (uasb) process treating sewage, uses polyurethane sponge as media to retain biomass. wastewater is trickled from the top of the reactor and purified by microorganisms retained both inside and outside of the sponge media as the wastewater flows vertically down thr...

introduction: preoperative psycho emotional preparation of patients is one of the principle purposes of anesthesia which can be achieved by administration of premedications. children should receive premedication before entering the operating room due to their dependence on parents and the fear and anxiety of separation from parents. different drugs are administered for this purpose, but conside...

the objective of this study was to investigate the effect of intranasal phototherapy on nasal microbial flora in patients with allergic rhinitis. this prospective, self-comparised, single blind study was performed on patients with a history of at least two years of moderate-to-severe perennial allergic rhinitis that was not controlled  by  anti-allergic drugs.  thirty-one  perennial  allergic r...

Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...

background marine sponge/nano-cuo as a natural catalyst efficiently catalyzed the sulfonylation reaction of p-chlorobenzene sulfonyl chlorides with amines in order to prepare sulfonamides. the advantages included use of a natural catalyst, ease of handling, requirement of a very small amount of catalyst, mild reaction condition and appropriateness to high yield. objectives the current study aim...
