Biomass can be used to generate heat, power, or biofuels in thermal conversion processes such as combustion, gasification and pyrolysis. However, some types of biomass contain high levels phosphorus, which released the gas phase cause operational environmental problems. The mechanism(s) responsible for phosphorus release has not been convincingly established. Understanding high-temperature chem...

A pot experiment was carried out at screen house, Faculty of Agriculture University Maiduguri to compare the effect NPK, bio-fertilizers and manures applications on growth nutrient uptake by maize. The consisted 9 treatments combined application NPK half full recommended rates for maize, Azotobacter chroococcum, Bacillus megaterium Pseudomonas fluorescence biofertilizers cow dung poultry replic...

The results of a field experiment to study the effect grassing in orchard and microbial preparations (MP) have been presented article. was carried out Crimea on meadow alluvial calcareous soil. Mixtures herbs (MH) were investigated: MH2 - multiflorous ryegrass + blue alfalfa; MH3 fescue clover; MH4 alfalfa clover awnless rump. Control is natural (NG). MP used: Azotobacterin (AB) Complex (CMP). ...

This work pointed out the effect of adding P2O5 and/or MnO2 on the crystallization behavior of magnetic glass ceramic in the system Fe2O3·ZnO·CaO·SiO2·B2O3. The differential thermal analysis of the quenched samples revealed decrease in the thermal effects by adding P2O5 and/or MnO2 to the base sample. The X-ray diffraction patterns show the development of nanometric magnetite crystals in a glas...

In the present work, effect of dephosphorization endpoint temperature on hot metal was studied for double slag converter steelmaking process under conditions low and basicity by industrial experiments. range 1350–1450 °C, with an increasing temperature, ratio phosphorus distribution first increase then decrease. The content in decreases increases at end dephosphorization. At 1385–1410 is higher...

Phosphorus (P) is one of the most limiting nutrients for growth and development crops, important soil fertility managements, since it affects quality fruits. With hypothesis that different levels irrigation phosphorus fertilization interfere in physical physicochemical properties tomatoes, objective this experiment was to verify analyze behavior fruits’ responses. The conducted a greenhouse at ...

Plasma-sprayed 45S5 bioactive glass coatings were manufactured using two types of powder feedstocks (commercial and lab-made glass) plasma torches (single triple cathode) to analyse their influence on the microstructure bioactivity coatings. Besides, volatilisation oxides such as Na2O P2O5 during deposition was studied. All microstructurally characterised by scanning electron microscopy, X-ray ...
