Ultrasound for knee effusion: lipohaemarthrosis and tibial fine particulate deposition in an effusion plate

An effusion is usually seen as a hypoechoic collection, however blood or purulent debris may create fine particulate material that makes the effusion more echogenic in appearance. The patient should be supine, with the knee resting on a pillow or other support, at 30 degrees flexion.The Effect of Particle Size on Deposition in an Effusion fine particulate deposition in an effusion plateParticle deposition tests were conducted on a flat plate effusion cooling geometry with six unique size distributions of Arizona Road Dust (ARD) within the range of 0- 20 µm. Results show a clear fine particulate deposition in an effusion plateSimulations of Multiphase Particle Deposition on a Gas fine particulate deposition in an effusion plateAug 18, 2015 · The deposition of the particles, which originate from impurities in the syngas fuels, can increase surface roughness and obstruct film cooling holes. These deposition effects increase heat transfer to the components and degrade the performance of cooling mechanisms, which are critical for maintaining component life.

QCR Used for Deposition Monitoring. The deposition monitoring was carried out by using an AT-cut QCR (9 MHz) with Au electrodes, connected to a frequency counter (Q-pod, Inficon). The QCR surface was rugged without fine polishing. The electrode of QCR substrate was opposite to the opening of the Al lid of effusion cell.Low-Vacuum Deposition of Glutamic Acid and Pyroglutamic fine particulate deposition in an effusion plateThe deposition monitoring was carried out by using an AT-cut QCR (9 MHz) with Au electrodes, connected to a frequency counter (Q-pod, Inficon).

Single mineral dusts made from five different minerals, Quartz, Dolomite, Albite, Salt, and Gypsum, were milled to similar size distributions (approx. 010m diameter).

Effect of particle shape on dry particle inhalation: study fine particulate deposition in an effusion plate

The shape effects of dry particles on flowability, aerosolization, and deposition properties in inhalation drug delivery are studied. The properties are compared with similar size range particles of different shapes such as sphere, needle, cube, plate, and pollen. Flowability of the particles is cha Coefficient of Restitution Testing | Turbine fine particulate deposition in an effusion plateParticulate Deposition > Coefficient of Restitution Testing One of the primary goals of current particle deposition research is to develop a physics-based model that, in conjunction with a fluid flow solver, can be used to accurately predict the deposition and rebound behavior of particles Atmospheric Chemistry | PNASApr 13, 2010 · The field of atmospheric chemistry is very broad, both in the problems addressed and in the approaches taken. Thus, it includes laboratory and theoretical studies, field measurements, and modeling, and addresses chemistry from the lower to the upper atmosphere, in remote and polluted regions, from marine to continental areas, and both outdoors and indoors.

An overview of particulate dry deposition: measuring fine particulate deposition in an effusion plate

lems, particles emission, transport, transformation and removal mechanisms have to be quantied at multiple scales. Dry and wet depositions are the two major removal mechanisms for atmospheric particles. Dry deposition is the removal process though which particles are taken up by the earths surface.
