found that the diversified rotations with sweet potato, soybean, and peanut significantly reduced net GHG emissions by 75–92% compared to the wheat–maize, spring maize→wheat–maize, and ryegrass-sweet sorghum→wheat–maize systems. In a study in Western Canada, cereals rotated with legumes dec...
The Chimney liner size requirement is determined by us. We calculate the chimney liner size required for the new gas boiler as well as the additional Btu of a hot water heater. The gas boiler Btu size also has to fall within the size specification of the existing chimney. For example: try...
The gas treatment systems are also maintained and monitored regularly, and these processes are used to identify opportunities for improving treatment efficiencies. The remaining sections of this chapter provide an overview of the current airborne emissions associated with the Olympic Dam operation...
(GHG) emissions; in contrast, rotation systems diversified with cash and legume crops can maintain crop yields, increase farmers’ income, and reduce GHG emissions due to the biological N2fixation by legumes partly substituting for synthetic N inputs. Legume-included rotations can also enhance soil...
Unfortunately, RMSE is magnitude dependent, meaning that larger systems have larger RMSE if the percent error is constant, which makes it a poor metric for comparing the performance of a model across different systems. Another common metric for evaluating forecasts is mean absolute percent error, M...
Field scale tests, on the other hand, investigate large-scale and longer term phenomena in heterogeneous systems under often uncontrollable conditions. Therefore, it is usually difficult to apply laboratory data directly to interpret the results of field tests. For example, laboratory studies can ...
