The Middle East frontal sand and dust storms (SDS) occur in non-summer seasons, and represent an important phenomenon of this region’s climate. Among the mentioned type, spring SDS are the most common. Trend analysis was used in the current study to investigate the spatial-temporal variability of springtime dust events in the Middle East...

WInDI: a Warp-Induced Dust Instability in protoplanetary discs

Aly, H.A. (author), Nealon, Rebecca (author), Gonzalez, Jean-François (author)

We identify a new dust instability that occurs in warped discs. The instability is caused by the oscillatory gas motions induced by the warp in the bending wave regime. We first demonstrate the instability using a local 1D (vertical) toy model based on the warped shearing box coordinates and investigate the effects of the warp magnitude and...

Pang, Mijie (author), Jin, J. (author), Segers, Arjo (author), Jiang, Huiya (author), Fang, Li (author), Lin, H.X. (author), Liao, Hong (author)

Super dust storms re-occurred over East Asia in 2021 spring and casted great health damages and property losses. It is essential to achieve an accurate dust forecast to reduce the damage for early warning. The forecasting system fundamentally relies on a numerical model which can forecast the full evolution of dust storms. However, large...

Poor indoor air quality is an important issue for public and occupational health worldwide. Location, air-tightness of the building, ventilation rate and resident activities play an important role on the concentration of indoor pollutants and subsequently on their effects on human health. While indoor air pollution in working environments has...

Zinc Vaporization and Self-reduction Behavior of Industrial Waste Residues for Recycling to the HIsarna Furnace

Kerry, T.J. (author), Peters, A.G.A. (author), Georgakopoulos, E. (author), Dugulan, A.I. (author), Meijer, Koen (author), Hage, Johannes (author), Offerman, S.E. (author), Yang, Y. (author)

Within the steelmaking industry, a large amount of zinc-bearing waste is produced which cannot be effectively treated through integrated steel mills. Concurrently, zinc smelters generate waste residues containing significant amounts of iron and zinc which are stored or landfilled. The zinc concentration of iron and steelmaking residues...

Asian mineral dust has been studied extensively for its role in affecting regional-to global-scale climate and for its deposits, which enable reconstructing Asian atmospheric circulation in the past. However, the timing and origin of the dust deposits remain debated. Numerous loess records have been reported across the Asian continent with...

Large-scale transportation and storage of wood pellets: Investigation of the change in physical properties

Gilvari, H. (author), van Battum, Coen H.H. (author), van Dijk, Simon A. (author), de Jong, W. (author), Schott, D.L. (author)

The change in physical properties of wood pellets, with a focus on particle size distributions due to pellet breakage and attrition, was studied in a large-scale (∼450 ton/h) transportation system. Critical locations with a high probability of breakage through the whole transportation system were chosen and sampled to study the effect of...

Field Observations of Atmospheric Aerosol Properties and the Impacts of New Particle Formation on the Radiative Properties of Clouds

Mamali, D. (author)

Atmospheric aerosol particles are solid or liquid particles suspended in the atmosphere. They are directly emitted into the atmosphere or they are formed via the oxidation of gaseous precursors. Understanding the behavior of particles in the atmosphere is particularly important because they can affect the Earth’s climate, visibility, air quality...

Zinc Reduction/Vaporisation Behaviour from Metallurgical Wastes

Kerry, T.J. (author), Peters, Alexander (author), Georgakopoulos, E. (author), Hosseini, A. (author), Offerman, S.E. (author), Yang, Y. (author)

The steelmaking industry produces large quantities of zinc-bearing wastes of varying forms that cannot be treated through integrated steelmaking processes. Simultaneously, by-products of the zinc industry containing great amounts of iron and zinc are stored or landfilled. The amount of zinc in these materials is generally below that which is...

Dust storm emission inversion using data assimilation

Jin, J. (author)

Severe dust storms present great threats to the environment, property and human health over the areas in the downwind of arid regions. Several dynamical dust models have been developed to predict the dust concentrations in the atmosphere. Currently, the accuracy of these models is limited mainly due to the imperfect modeling of dust emissions....

Aerosol optical depths (AODs) from the new Himawari-8 satellite instrument have been assimilated in a dust simulation model over East Asia. This advanced geostationary instrument is capable of monitoring the East Asian dust storms which usually have great spatial and temporal variability. The quality of the data has been verified through a...

Minimizing aerosol bone dust during autopsies

Pluim, Jip M.E. (author), Loeve, A.J. (author), Gerretsen, Reza R.R. (author)

When sawing bone for medical or medico-legal procedures, fine, airborne dust is produced (aerosols) that can pose a health hazard when inhaled. The aim of this study was to determine the influence of saw blade frequency and contact load, bone condition, test environment, and saw blade type, on the production of aerosol particles. A custom...

Explosion hazards of aluminum finishing operations

Taveau, J.R. (author), Hochgreb, Simone (author), Lemkowitz, S.M. (author), Roekaerts, D.J.E.M. (author)

Metal dust deflagrations have become increasingly common in recent years. They are also more devastating than deflagrations involving organic materials, owing to metals' higher heat of combustion, rate of pressure rise, explosion pressure and flame temperature. Aluminum finishing operations offer a particularly significant hazard from the...

Aerosol production during autopsies: The risk of sawing in bone

Pluim, Jip M.E. (author), Jimenez-Bou, Lucas (author), Gerretsen, Reza R.R. (author), Loeve, A.J. (author)

When sawing during autopsies on human remains, fine dust is produced, which consists of particles of sizes that may fall within the human respirable range, and can act as vectors for pathogens. The goal of this study was to explore the potential effects of saw blade frequency and saw blade contact load on the number and size of airborne bone...

We present [C ii] 158 μm measurements from over 15,000 resolved regions within 54 nearby galaxies of the Kingfish program to investigate the so-called [C ii] "line-cooling deficit" long known to occur in galaxies with different luminosities. The [C ii]/TIR ratio ranges from above 1% to below 0.1% in the sample, with a mean value of 0.48 ± 0...

Igniter-induced hybrids in the 20-l sphere

Taveau, J.R. (author), Going, J. E. (author), Hochgreb, S. (author), Lemkowitz, S.M. (author), Roekaerts, D.J.E.M. (author)

Dust explosibility is traditionally described by two parameters, namely the maximum explosion pressure, P_max, and the deflagration index, K_St, usually determined through testing in a closed, pressure-resistant spherical vessel, either 20 L or 1 m³ in volume. These parameters constitute key variables in the...
