Control of Insects in Post-Harvest: Inert Dusts and Mechanical Means

2001
Residual chemicals are currently used to control stored-product insects pests that are found in granaries and food-processing facilities. Long-term use of these chemicals has resulted in the development of insect populations that are resistant to the common insecticides (e.g.

A flame inhibition theory by inert dust and spray

Combustion and Flame, 1981
An asymptotic analysis for the limit of large activation energy is presented to study the thermal inhibition effect on premixed flames by chemically inert dust or spray. A formulation analogous to heterogeneous laminar flame is employed to derive explicit relations of flame speeds and characteristics of dust and spray. The flame propagation velocity in

On the problem of laminar flame propagation in a gas with an inert dust

Combustion, Explosion, and Shock Waves, 2011
This paper presents a mathematical model and the results of calculation of the velocity of propagation of the flame front in a fuel gas with suspended inert particles taking into account the thermal expansion of the gas and the dynamic relaxation of particles.

Human response to controlled levels of inert dust.

The American review of respiratory disease, 1979
We studied nasal mucous flow, airway resistance, and subjective response in 16 young healthy subjects during 5-hour exposures to 2, 10, and 25 mg of inert dust per m3 in an environmental chamber. The dust was a fully polymerized plastic dust containing carbon black.

Inert dust insecticides: Part I. Mechanism of action

Annals of Applied Biology, 1944
The mode of action of inert dust insecticides on the grain weevil (Calandra granaria L.) has been investigated by determination of mortality‐time curves and by a detailed study of the influence of dusts on the water relations of the insects. It has been found that dusts do not depend for their action on any chemical reactivity, some highly inert ...

Effect of Inerts on Layer Ignition Temperatures of Coal Dust

Combustion and Flame, 1998
An experimental study into the hot surface ignition of coal dust layers has been conducted. Two coals were examined: Prince coal from the Cape Breton Development Corporation and Pittsburgh coal from the United States Bureau of Mines. The effect of admixed inerts (dolomite and limestone) on the dust layer ignition temperature has been analyzed using a ...

Reducing aluminum dust explosion hazards: Case study of dust inerting in an aluminum buffing operation

Journal of Hazardous Materials, 2008
Metal powders or dusts can represent significant dust explosion hazards in industry, due to their relatively low ignition energy and high explosivity. The hazard is well known in industries that produce or use aluminum powders, but is sometimes not recognized by facilities that produce aluminum dust as a byproduct of bulk aluminum processing.

Smoking impairs alveolar macrophage activation after inert dust exposure

Toxicology Letters, 1996
Magnetopneumography was applied to investigate intracellular phagosome motion in alveolar macrophage cells of healthy subjects (non-smokers and smokers). Ingested magnetic microparticles are inhaled and phagocytized by alveolar macrophages within hours. Thereby the particles are transferred into phagolysosomes. After magnetization the particles produce

The quantitative studies on gas explosion suppression by an inert rock dust deposit

Journal of Hazardous Materials, 2018
The traditional defence against propagating gas explosions is the application of dry rock dust, but not much quantitative study on explosion suppression of rock dust has been made. Based on the theories of fluid dynamics and combustion, a simulated study on the propagation of premixed gas explosion suppressed by deposited inert rock dust layer is ...

Solid inertants and their use in dust explosion prevention and mitigation

Journal of Loss Prevention in the Process Industries, 2006
This paper is a review of the use of inert dusts to reduce the risk of dust explosions through both prevention and mitigation schemes. The review is conducted by referring primarily to the research results of the author and his colleagues in this area, with appropriate reference to the work of other researchers.
