MANAGEMENT of post-harvest residues, produced during the green-cane harvesting of sugarcane in Louisiana, has become an increasingly important issue for producers, particularly in areas where burning of the residues is banned or restricted. If the residues, which range from 4–8 tonnes per hectare, are not removed prior to the emergence of the subsequent ratoon crop in the spring, yields may be ...

TG-FTIR and PY-GC/MS were used to analyze the pyrolysis behaviors of pine wood, urea-formaldehyde resin (UF resin) their blended pellets. The process was divided into three stages: water evaporation, devolatilization residue decomposition. During pellets, with increase addition ratio UF resin, peak value weight loss decreased in decomposition stage residue, while temperature shifted low-tempera...

The incorporation of rice residues into paddy fields strongly enhances methane production and emissions. Although the decomposition processes of plant residues in rice field soil has been documented, the structure and dynamics of the microbial communities involved are poorly understood. The purpose of the present study was to determine the dynamics of short-chain fatty acids and the structure o...

wind erosion. Soil microenvironments are different in fields that have surface-crop residues than in tilled fields Conservation tillage fields provide different environments for biowith incorporated residues. Natural-resource simulation logical and chemical processes than tilled fields. Our understanding of decomposition does not adequately account for post-harvest residue models that address s...

Elevated atmospheric CO2 concentration can increase biomass production and alter tissue composition. Shifts in both quantity and quality of crop residue may alter carbon (C) and nitrogen (N) dynamics and management considerations in future CO2-enriched agroecosystems. This study was conducted to determine decomposition rates of the legume soybean [Glycine max (L.) Merr.] and nonlegume grain sor...

Current research suggests that genetic modification of commercial crops may lead to indirect effects on ecosystem function (i.e. decomposition and nutrient cycling processes). We investigated residue decomposition of cotton that was genetically modified to express an endotoxin insecticide isolated from Bacillus thuringiensis (Bt) and/or glyphosate tolerance (Roundup Ready®). Decomposition of th...

Previous work on Empirical Mode Decomposition in two dimensions typically generates a residue with many extrema points. In this paper we propose an improved method to decompose an image into a number of Intrinsic Mode Functions and a residue image with a minimum number of extrema points. We further propose a method for the variable sampling of the two-dimensional Empirical Mode Decomposition. S...

This paper proposes a novel tree decomposition based side-chain assignment algorithm, which can obtain the globally optimal solution of the side-chain packing problem very efficiently. Theoretically, the computational complexity of this algorithm isO((N +M)n rot ) whereN is the number of residues in the protein,M the number of interacting residue pairs, nrot the average number of rotamers for e...
