rivers are one of the most valuable aquatic ecosystems that their physiochemical properties and the biology of their organisms have strong interactions. one of the major rivers in iran, which covers a variety of ecosystems, is called tajan river. in this research, the effect of different pollution sources on water quality of this water body was investigated. samples were collected in seven diff...

Bio-inoculants (Biofertilizer) are an agricultural input that helps to keep the environment clean. By definition biofertilizers efficient strains of isolated microorganisms help plants grow in a variety ways, both directly and indirectly. Biological nitrogen fixation, phosphate solubilization, mobilisation, siderophore generation phytohormone production some direct methods. The majority bio-ino...

the bulk of our knowledge on immunosuppression in malnutrition comes from the experiments done on cell-mediated immunity. however, malnutrition-induced modifications of humoral immunity have been less understood. the objective of this study was to determine the effects of acute protein-energy malnutrition on serum levels of immunoglobulins and their subclasses in murine models. male and female ...

Phosphate tailings pose significant risk to the environment as point sources of basic, carbonate-rich effluents. This waste may be judiciously used for the biofertilizer preparation. The enrichment of compost by adding low grade rock phosphate also offers a potential preposition for the effective utilization of insoluble P. Experimentally, the compostable material (Biogas spent slurry) is mixed...

iron is an essential microelement for plant growth. low content of organic matter and excess application of phosphate fertilizer in soils can be affected on availability of iron. in this study the effect of iron, phosphorus and organic matter on growth and iron uptake of mays was evaluated. a greenhouse experiment was conducted with two levels of cattle manure (0 and 1 %), three levels of phosp...
