cadmium oxide rhombus-shaped nanostructure was synthesized using hydrothermal process followed by heating treatment. clearly, x-ray diffraction pattern demonstrated the formation of cdo crystalline phase. scanning electron microscopy (sem) showed that the obtained rhombus-like structure is composed of nanoparticles with the average size of 29 nm. in addition, we evaluated adsorption of organic ...

the objective of this study was to assess the microbial contamination of razavi khorasan (iran) hot red pepper. the natural occurrence of aflatoxins and ochratoxin a in those samples was also investigated. for this purpose, 36 samples of this kind of pepper were collected from a farm and sun-dried. standard and established methods were used for both microbiological analyses and mycotoxins ident...

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). in this investigation photocatalytic degradation of acid red 206 in wa...

shigellosis is an acute gastroenteritis caused by shigella species. the purpose of this study was to determine plasmid profile, antibiotic resistance and phenotypic virulent by congo red between s. flexneri strains. the isolated bacteria were identified by standard bacterial and biochemical methods. plasmids were isolated by alkaline lysis method. antibiotic susceptibility test was performed ac...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

OBJECTIVE This study aimed to analyze the incidence of colorectal cancer in 15 European countries in recent decades and the relationship between the incidence found and changes in dietary habits. METHODS Pearson's or Spearman's correlation coefficients were calculated by comparing incidence rates obtained from the International Agency for Research on Cancer for 1971-2002 with data on per capi...
