grass (Mueller-Warrant and Brewster, 1986), common occurrences in grass seed fields. Seed laws and market Effective weed control was a major concern of Oregon grass seed expectations define allowable limits for weed seed congrowers during their recent transition from open-field burning to mechanical methods of managing post-harvest residues. This 4-yr herbitamination, but production efficiency ...

Understanding the impacts of long-term agricultural practices on soil quality (SQ) is key for sustaining agroecosystem productivity. This study investigated conventional and no-tillage (NT), residue burning no burning, level (high low), irrigation (irrigated dryland) effects properties, SQ, crop yields following 16 yr a wheat (Triticum aestivum L.)–soybean [Glycine max (L.) Merr.] double-crop s...

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

Abstract The effect of particle size distribution and compaction pressure wood residues briquette was investigated. Starch used as a binder. Concerning that the have valuable content namely lignin cellulose, high possibility to be modified biofuel. In this study, (iron gelam woods) were treated by drying, milling, carbonization at 500 °C. ratio between carbonize binders 20% weight. manufactured...

This study was undertaken to compare the chemical properties and yields of pineapple leaf residue (PLR) char produced by field burning (CF) with that produced by a partial combustion of air-dried PLR at 340 °C for 3 h in a furnace (CL). Higher total C, lignin content, and yield from CL as well as the presence of aromatic compounds in the Fourier Transform Infrared spectra of the char produced f...

Crop residue burning in Indian Punjab emits particulate matter with detrimental impacts on health, climate and that threaten agricultural production. Though legal technological barriers to exist – alternatives considered more profitable farmers continues. We review black carbon (BC) emissions from Punjab, analyse social-ecological processes driving burning, rice wheat value-chains. Our aims are...

Effect of ash content in coal dust on the burning characteristics tuyere zone blast furnace is studied. The considered as an individual fraction addition to two fractions dust. It shown, that variation pulverized fractional composition allows increase carbon monoxide yield and fuel particles burnout. presence results oxygen extension coke residue At same time total burnout lower than low-ash co...

Military training with howitzers and mortars produces excess propellant that is burned on the training range and can result in point sources containing high concentrations of unreacted propellant constituents. Propellants contain energetic compounds such as nitroglycerin (NG) and 2,4-dinitrotoluene (2,4-DNT), both of which are found at firing positions and propellant disposal areas. To quantify...
