Yellow-poplar growth has been improved by NPK fertilizers on eroded sites in the Silty Uplands, and in the greenhouse sycamor...
The wood used in the construction of musical instruments is carefully selected, being best quality from point view structure. However, depending on anatomical characteristics wood, resonance classified into classes. For example, sycamore maple with curly grains appreciated by luthiers for its three-dimensional optical effect. This study highlights statistical correlations between physical and a...
The role of vegetation in mitigating the effects of PM(10) pollution has been highlighted as one potential benefit of urban greenspace. An integrated modelling approach is presented which utilises air dispersion (ADMS-Urban) and particulate interception (UFORE) to predict the PM(10) concentrations both before and after greenspace establishment, using a 10 x 10 km area of East London Green Grid ...
