introduction: application of organic fertilizers in agricultural soils with low organic matter content is one of the best ways of nutrientsaddition to these soils. different organic fertilizers have different effects on nutrient availability in soil. moreover study of the distribution of nutrients in the soil allows investigating their mobility and bioavailability. the nutrients availability an...

Comparative microstructural studies and mechanical tests of an experimental austenic manganese alloy typical structural materials have been carried out. As a result the research, relative data revealed, indicating high properties alloy, which makes it possible to recommend for machine parts operating at load-speed conditions temperature exposure up 700 0C.

This article examines the resistance of corrosion-resistant polymeric materials to chemical reagents and degree corrosion, taking into account direction corrosion processes. One main factors that determined rate is air humidity dust released atmosphere during industrial emissions. Mixtures based on polymer can be used gum up apparatus equipment; for protection, expensive are required. The sampl...

The objective of this study was to work out different blends of oils amongst rice bran oil (RBO), soybean oil (SBO), and mustard oil (MO) to obtain a unique blend of oil having better shelf life. Further, in present work, the effect of synthetic antioxidant such as butylated-hydroxyanisol (BHA), butylhydroxyltoluene (BHT) and t-butyl-hydroxyquinone (TBHQ) were also evaluated by adding upto reco...
