We study the structure and properties of hot MHD accretion onto a Kerr black hole. In such a system, the hole is magnetically coupled to the inflowing gas and exerts a torque onto the accretion flow. A hot settling flow can form around the hole and transport the angular momentum outward, to the outer edge of the flow. Unlike other hot flows, such as advectionand convection-dominated flows and i...

To evaluate the influence of episodic events on particle and hydrophobic organic contaminant (HOC) cycling in the Great Lakes, we deployed sequencing sediment traps at two locations in the western arm of Grand Traverse Bay, Lake Michigan. The traps collected integrated samples of settling particles every 2 weeks from May 1997 to September 1999. The total polycyclic aromatic hydrocarbon (t-PAH) ...

Many stormwater management practices depend on sedimentation as their primary removal mechanism, but the settling velocity distribution of particles in runoff from a specific watershed is rarely known. A simple and effective method to characterize settling velocity distribution is needed to improve the design of stormwater management practices. Elutriation devices have been used to characterize...

It is well known that the permeability and density of an aggregate decreases with its size, affecting its settling velocity and coagulation rate (rate of particle capture) with other particles. This change in aggregate density with size can be described by fractal scaling relationships. Two distinctly different fractal scaling approaches, however, have been used to describe aggregate permeabili...

Introduction: In a switch-capacitor realisation of the multiplying digitalto-analogue converter (MDAC) used in algorithmic and pipeline analogue-to-digital converters (ADCs), the settling behaviour of the opamp determines the speed and accuracy of the ADC. Fast settling requires high unity gain bandwidth, while accurate settling requires a high DC gain. As gate lengths continue to shorten, high...
