three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in finike bay for red mullet (mullus barbatus l., 1758). the sampling program was arranged during february to may 2012. holt (1963) method was used for selectivity of trammel nets. red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...

this study was conducted to compare different propagation methods and two cultivars (azarshar red, and kashan white) as a rcbd in factorial with four replications in shirvan in 2001. in azarshar red onion, high yield belonged to sets method that 30 percent more than seed sowing. in kashan white bulb cultivar, high yield was get from seedling cultivation and there were no significant differences...

background: recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. reactive dyes are widely used in textile industry. advanced oxidation processes are one of the cost-effective methods for the removal of these dyes. the main aims of this study were determining the feasibility of...

keratocystic odontogenic tumor (kcot) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. peripheral kcots are very uncommon. here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...

background and objective: there is a concern on safety of human fresh frozen plasma (ffp) as it is a source of some medicinal products. the possibility of transmission of blood-borne are reported often due to emerging viruses. there are some pathogen reduction technologies (prt) to inactivate viruses. methylene blue (mb) based method is one of them. the aim of this study was to examine new desi...

a method was developed for removal, preconcentration and spectrophotometric determination of trace amounts of methyl red based on sio2-coated fe3o4magnetic nanoparticles. the influence of ph, dosage of adsorbent and contact time on the adsorption of dye was explored by central composite design. the kinetic data were analyzed based on the langmuir and freundlich adsorption isotherms. the langmui...

abstract introduction: dyes are among the most hazardous chemicals in industrial wastesdue to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. the current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. materials & methods: in this experim...

in this work, efficiency and performance of hazelnut shells (hs) adsorbent was examined for the removal and recovery of direct red 12b (dr12b) from wastewater. the absorbance of dr12b was measured spectrophotometrically at λmax=523 nm before and after adsorption of dr12b. the maximum removal was 99.8% for 30 mg l –1 ofdr12b concentration on 0.3 gr hs adsorbent. acidic ph was favourable for the ...

in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). photocatalytic degradation of acid red 206 in water was studied. cufe2...
