Significance of large peat blocks for river channel habitat and stream organic budgets [PDF]

Mires and Peat, 2007
This paper examines the significance of large peat blocks in Trout Beck, an upland gravel-bed river in northern England. An inventory was made of all in-channel peat blocks over a 1.5 km reach of the river in order to characterise the distribution of the

Sedimentation of a Fine Aerosol in the Acoustic Field and with the Electrostatic Charge of Particles

Archives of Acoustics, 2018
Finding an efficient way to eliminate fine dust (particle diameter of 1–15 μm) from a room can be a challenging problem. Acoustic radiation emitters are widely used to accelerate particle coagulation and sedimentation.
