in this study, the potential of biosorbent obtained from silk maze, was investigated for the batch biosorption of direct red 81 (dr 81) in aqueous solution. the effects of temperature, biosorbent amount, contact time, initial dye concentration and ultrasonic irradiation were also evaluated. furthermore, experimental equilibrium and kinetics data were fitted by langmuir and freundlich isotherms ...

background: host immune system response against blood group antigens is a major problem in blood transfusions, especially forthalassemic patients. thus, an approach was proposed coating the red blood cell (rbc) surface by polyethylene glycol.objectives: this study aimed to obtain the optimal simultaneous camouflge of the major and minor antigens by activated methoxypolyethylene glycol (mpeg) wi...

tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...

there is evidence indicating that pomegranate juice contains many of the essential properties necessary to retain cell viability and cell proliferation. these properties indicate that pomegranate juice is a suitable storage medium for avulsed teeth. however, this idea has not yet been tested. in this study, the capacity of pomegranate juice (pj) as a storage medium for retaining avulsed teeth w...

the aim of this study was to compare invasive and non-invasive strains of shigella flexneri isolated from tehran by a 120 kda protein band by sds-page, electron microscopy of cell culture and congo red dye methods. methods: s. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. phenotype analysis for screening vi...

Orussus melanosoma Lee & Wei, sp. nov. from South Korea is described and illustrated. Phylogenetic analyses place the new species basally in Orussus, together with other species from the Far East. A key to species of Orussidae from the eastern Palaearctic is provided. 

Jajarm Alumina Plant, the only Alumina powder producer in Iran, generates 500,000 tons of red mud annually. The commonest method for final disposal of red mud in Iran is Tailing dam which is neither cost-effective nor environmentally-friendly. The main objective of this study is to evaluate the possibility of red mud recovery to be used for stabilization of loose soils. Red mud samples have bee...

OBJECTIVES Two studies explored the relative efficacy of a morality-based versus a competence-based self-affirmation manipulation at increasing acceptance of personally relevant health risk information. In accordance with prior theorizing (e.g., Cohen & Sherman, 2014), it was hypothesized that the morality affirmation would be more effective than the competence affirmation in such contexts, as ...
