fecal samples of 60 turkey poults that showed chronic progressive symptoms like unthriftiness, loss ofweight, diarrhea were collected from the most rural areas with high rate of turkey population in north andwest part of country for intestinal protozoan parasites. according to the morphological characteristics, likeshape, presence or absence of micropyle, and/or polar granule, the 5 different t...

incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

reactive oxygen species cause to release of dormancy in many plants such as sunflower seeds. this study investigated in order to evaluation role of reactive oxygen species germination and lipid proxidation in sunflower seeds. this study was performed in two separate experiments, each in a completely randomized design with factorial design with four replications.  in both experiments, uses from ...
