Ultrasonic agitation for surface plasmon resonance biosensors
Due to their biocompatibility and ability to yield a localised surface plasmon resonance, surface-based nanoparticles have gained popularity in various biosensing applications. In such configurations, fluid containing biological material such as proteins is injected into a static cell containing …

Radial parallel plate flow with mechanical agitation
Computer processors have significant and rising cooling requirements, with electronics cooling estimated to consume 1% of global energy consumption. An integrated fan heat sink was designed to help alleviate this issue, and is designed to simultaneously improve heat transfer and efficiency. Current …

The effect of agitation on the biochemical oxygen demand sewage
… this investigation was to determine what effect agitation had upon the biochemical oxygen demand of sewage. In order to determine the effect of agitation, the composition of the sewage, the seed source, the temperature and the dilutions were held constant.

Mechanical Agitation Effects on Physical Properties of Calcium-Silicate-Cement Sealers
… setting reactions and effects of mechanical agitation on flow, film thickness, and setting time of calcium-silicate-cement sealer (EndoSequence Bioceramic sealer). Single-paste bioceramic sealer (Brasseler, USA) was agitated for 10 seconds using a vortex mixer to assess flow, film thickness, …

Fluid Agitation Studies for Drug Product Containers Using Computational Fluid Dynamics
… undesired particles using a high speed spin-stop agitation process. To better understand the fluid movements to swirl the particles away from the walls, Computational Fluid Dynamics (CFD) is used to analyze the nature of the two phase flow of air and a liquid solution.</p> <p>Several 2-D and 3-D …

Agitation, mixing and mass transfer in simulated high viscosity fermentation broths
Gas-liquid mass transfer, agitator power consumption, rheology, gas-liquid mixing and gas hold-up have been studied in an agitated, sparged vessel of diameter, T = 0.3 m, with a liquid capacity of 0.02 m\(^3\), unaerated liquid height = 0.3 m. The solutions of sodium carboxymethylcellulose used …

Disruption of microorganisms due to agitation in slurries of fine particles
… most widely used industrial process involving agitation of microorganisms in slurries of particles in stirred tanks is the biooxidation process. Mixed cultures of thiobacilli are used in stirred tank reactors for the biooxidation of sulphide minerals. In addition to operating conditions, the …

Burning protests, the rhetoric of agitation and control of the journey of harmony tour
… artifact through the model of the rhetoric of agitation and control created by Bowers, Ochs, and Jensen (1993) and symbolic interaction. This study . found that the Chinese government (the control) created the counter-movement to suppress and provide a counter-persuasion to the movement. To …

Experimental determination of the agitation requirements for solids suspension in dissolution systems using a mini paddle apparatus
… available on mini vessels, and especially on the agitation speed needed to prevent "coning" effects. Typically during dissolution testing, a disintegrating tablet becomes rapidly fragmented, and the resulting solid particles may or may not become suspended depending on the agitation speed of the …

Minimum agitation speed for solid suspension and mixing time in a torispherical -bottomed pharmaceutical stirred tank under different baffling conditions
The minimum agitation speed, NS, required to just suspend solid particles dispersed in water was experimentally determined in this work for a glass-lined type of mixing tank provided with a torispherical bottom and agitated with a retreat-blade impeller under different baffling configurations. Ns …

Novel experimental method for the determination of the minimum agitation speed for solids suspension in flat-bottomed stirred tank reactors
Knowledge of the minimum agitation speed, Njs, required to suspend finely divided solids in vessels stirred by an impeller is a critical parameter to properly operate industrial tanks in a large number of industrial operations. The most common experimental approach to measure N_{js} is that of …
