The sustainable management of forest plantations by keeping the harvest residues on site improves soil’s chemical, physical and biological properties while constituting an important nutrient reserve. Our objectives were: (a) to identify quantify characteristics Eucalyptus dunnii, grandis globulus that affect decomposition rates residues, as well indicators can explain process (b) potential recy...

Crop residues are among the main inputs that allow organic carbon (C) and nutrients to be maintained in agricultural soil. It is an important management strategy can improve soil fertility enhance productivity. This work aims evaluate extent of changes may occur heterotrophic microbial communities involved matter decomposition C nitrogen (N) mineralization after addition crop residues. Soil mic...

The thermal decomposition characteristics of microwave liquefied rape straw residues with respect to liquefaction condition and pyrolysis conversion were investigated using a thermogravimetric (TG) analyzer at the heating rates of 5, 20, 50 C min. The hemicellulose decomposition peak was absent at the derivative thermogravimetric analysis (DTG) curve of liquefied residues, because it had been d...

In this paper, memory optimization and architectural level modifications are introduced for realizing the low power <span lang="EN-US">residue number system (RNS) with improved flexibility electroencephalograph (EEG) signal classification. The proposed RNS framework is intended to maximize reconfigurability of high-performance finite impulse response (FIR) filter design. By replacing exis...

in order to study the residues of phosphorous insecticides in mazandaran district of iran, ethion, azinphosmethyl, diazinon and malathion four most used pesticides were chosen and river water samples were collected in april to sept. 2000, throughout the mazandaran state. thin layer chromatography was used, since it was the best applicable method in area with reasonably high level of sensitivity...
