the effects of natural zeolite as a bed medium in increasing lettuce and red tilapia growth as well as improvement of water quality parameters in an aquaponic system were investigated. an experiment with a completely randomized design was run with two treatments in triplicates, 1) an aquaponic system without use of zeolite as a control group and 2) use of a small cotton bag, containing 10 g zeo...

almond red leaf blotch is the most important fungal disease that is caused by the fungus polystigma amygdalinum. symptoms depending on the cultivar almond trees can be seen almost all year. in this study the effect of 5 fungicides (copper oxychloride  2000 µg/ml, bordofix 2000 µg/ml, mancozeb 200 µg/ml, bordo compound 10000 µg/ml, triforin 300 µg/ml with rep.control) was examined in a randomize...

background and purpose: textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. in the present study, multi-walled carbon nanotubes (mwcnts) were used as an adsorbent for the removal of reactive red-120 (...

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...
