In most theories of laminar flame spread over solid combustibles, radiation is neglected. However, when gas motion is completely absent, which may occur in the quiescent, microgravity environment of a spacecraft, the importance of radiation compared to convection is enhanced. We develop a theoretica

The rising velocity of an isolated bubble in a "two-dimensional" air-fluidised bed has been measured and found to be wel1 described by the relation, ub= 15'9Abf cm/sec, where Ab is the area of the bubble measured in cm\*. This predicts a smaller rising velocity than the corresponding @avies and Tayl
An improved electroresistivity probe has been used in a freely bubbling gas-fluidised bed of carbon particles to give the distributions of velocitj and size of bubbles therein. Bubble properties agree with previous observations but the significant influence of macro-circulation patterns on bubble ve

## Abstract The performance of the PanβEuropean Soil Erosion Risk Assessment (PESERA) model was evaluated by comparison with existing soil erosion data collected in plots under different land uses and climate conditions in Europe. In order to identify the most important sources of error, the PESERA
