Risk is quintessential in agricultural activities and the introduction of innovation in a farm always implies additional risks difficult to quantify and identify in advance. Surely farm’s internal and...
A comparison of oxygen diffusion rates in sand moistened with water or peg 20000 solution
ODR PEG solutions water/sand/air mixtures
2008/11/26
Oxygen diffusion rates (ODR) were measured in water/sand/air and PEG solution/sand/air mixtures, spanning a range of liquid/solid/air volume ratios. Replacement of water with PEG solution as the liqu...
Methane oxidation in homogenous soil covers of landfills: a finite ?element analysis of the influence of gas diffusion coefficient
landfills methanotrophic capacity methane oxidation modelling gas diffussivity
2008/11/14
Methane produced in municipal landfills covered with a soil layer diffuses to the atmosphere. Counterdiffusion of oxygen down the soil creates an oxic zone where biochemical oxidation of methane by me...
