BACKGROUND The WTC collapse exposed over 300,000 people to high concentrations of WTC-PM; particulates up to ∼50 mm were recovered from rescue workers' lungs. Elevated MDC and GM-CSF independently predicted subsequent lung injury in WTC-PM-exposed workers. Our hypotheses are that components of WTC dust strongly induce GM-CSF and MDC in AM; and that these two risk factors are in separate inflamm...
Simulations of the flow of concentrated aggregated colloidal systems, at the particulate level, are used to investigate the distribution of stresses in the shear-thinning regime. It is found that the distribution of shear stress carried by interparticle bonds decays approximately exponentially at large stresses, but with a double-exponential distribution for values of positive stress. The micro...
We present results of interface-resolved simulations heat transfer in suspensions finite-size neutrally-buoyant spherical particles for solid volume fractions up to 35% and bulk Reynolds numbers from 500 5600. An Immersed Boundary–Volume Fluid method is used solve the energy equation fluid phase. relate regimes particle motion previously identified, i.e. a viscous regime at low number, particle...
Transformations of dissolved iron and phosphate to particulate material (>0.2 pm) were investigated by adding 55FeC1, and 32P0,3to pH adjusted epilimnetic lake water samples of contrasting ionic strengths and dissolved humic substances (DHS) concentrations. The distributions of these tracers between particulate size fractions in samples without appreciable DHS after 24 h of dark incubation vari...
Particle size is a key variable in understanding the behaviour of particulate products that underpin much our modern lives. Typically obtained from suspensions at rest, measuring particle under flowing conditions would enable advances for in-line testing during manufacture and high-throughput development. However, samples are often turbid, multiply scattering light preventing direct use common ...
Background and Objective: The presence of fungal bioaerosols in hospitals indoor environments have affected the health of patients with the defect in immunity system. Therefore, determination of the rate and species of these agents is essential. This study aimed to investigate association between fungi contamination and particulate matter (PM10, PM2.5 and PM1) concentrations in the main indoor ...
Background & Aims of the Study: Particulate matters less than 10 microns can absorb into your lungs and reacting with the moisture and enter the circulatory system directly through the airways. The aim of this study is to assess Behavior PM 10 data in different seasons and Determination effects on human health in Ahvaz city during 2013. Materials & Methods: Data Particulate matters less than 10...
