Dust Control in Rock Drilling [PDF]

American Journal of Public Health and the Nations Health, 1940
THE importance of silicosis as an occupational disease has been demonstrated in many industries. Such investigations have shown rock drilling in hard-rock mining and other drilling operations to be hazardous, even including open drilling in quarries, road construction, and building excavation.

Effect of improved home ventilation on asthma control and house dust mite allergen levels [PDF]

, 2009
The warm, humid environment in modern homes favours the dust mite population, but the effect of improved home ventilation on asthma control has not been established.

Prediction of heterogeneous nucleation condensation effect on the surface of respiratory coal dust and test of dust reduction test

Meitan xuebao
Surface wettability of coal dust particles is an important factor restricting the efficiency of wet dust removal. Heterogeneous nucleation condensation on the surface of coal dust particles is a means without any pollution, without considering the ...

Characterization of explosion propagation of coal dust deposited by gas explosion convolutions in closed pipelines

Meitan xuebao
To explore the propagation characteristics of gas explosion-induced coal dust detonations in enclosed pipelines, a custom-developed experimental system was employed for gas explosions involving accumulated coal dust.

Guidelines for the Use of Synthetic Fluid Dust Control Palliatives on Unpaved Roads [PDF]

, 2017
The amount of small soil particles, dust, lost from typical unpaved roads to fugitive dust is staggering. A 1 km stretch of unpaved road can contribute over 2400 kg of dust to the atmosphere (4.2 ton/mile) in a typical 3-month summer season.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

FEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Effectiveness of Protein and Polysaccharide Biopolymers as Dust Suppressants on Mine Soils: Results from Wind Tunnel and Penetrometer Testing

Applied Sciences, 2023
For the dust control of barren mine soils, protein and polysaccharide biopolymers have recently shown potential as environmentally friendly alternatives to conventional dust suppressants (e.g., salt brines or petroleum-based products).

Laboratory Procedure for Measuring the Effectiveness of Dust Control Palliatives [PDF]

, 2017
Creation of fugitive dust on unpaved roads results in the loss of up to 25 mm (one inch) of surface aggregate annually (FHWA, 1998). On these roads, shearing forces created by vehicles dislodge the fine aggregate fraction (silt and clay) that binds the ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

FEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...
