Transport of estuarine sediment have a highly complex method, which is the combined effects result periodically reciprocating flow, ocean waves, and electrochemical characteristic sea water [1]. Settling velocity (SV) such parameter fundamental for researchers so that its accurate resolution has been regarded as top priority in correcting modelling numerical conceptual understanding fine dynami...

Abstract In this work we investigated the impact of filtering and subgrid-scale modeling on particle settling velocity collision-related statistics in a turbulent flow. To reduce complexity task first studied motion inertial particles low-pass filtered homogeneous isotropic turbulence, which was subsequently enriched with components obtained from frozen high-pass field. Particular emphasis has ...

In this study, we performed one dimensional cylindrical sedimentation tests to investigate the impact of clay mineralogy, ionic concentration, valence on sedimentation, and self-consolidation behavior clay. The result at 1,000% 2,000% water content indicates that = showed higher coefficient initial settling velocity, faster initiation termination self-consolidation. Additionally, velocity decre...

Aerobic granular sludge is attractive for high-rate biological wastewater treatment. Biomass wash-out conditions stimulate the formation of aerobic granules. Deteriorated performances in biomass settling and nutrient removal during start-up have however often been reported. The effect of wash-out dynamics was investigated on bacterial selection, biomass settling behavior, and metabolic activiti...

It has been known for a long time (Mestel 1953) that the meridional circulation velocity in stars, in the presence of μ-gradients, is the sum of two terms, one due to the classical thermal imbalance (Ω-currents) and the other one due to the induced horizontal μ-gradients (μ-induced currents, or μ-currents in short). In the most general cases, μ-currents are opposite to Ω-currents. Simple expres...

Conventional water treatment plant generates two types of process wastes, filter back wash water and sludge. Characteristic studies of these wastes reveals that it contains high solids content, metals and bacteriological concentration, which are generally more than permissible disposable standards. Direct disposal of these wastes in to natural stream pollutes the receiving streams, affects huma...

Palmer amaranth is resistant to several herbicides, including glyphosate, and there is concern that the resistance traits can be transferred between spatially segregated populations via pollen movement. The objective of this study was to describe the physical properties of Palmer amaranth pollen, specifically size, density, and settling velocity (Vs), that influence pollen flight. The mean diam...
