The trapping of dust particles has been observed in a dc abnormal glow discharge dominated by electron attachment. A dust cloud of several tens of positively charged particles was found to form in the anode sheath region. An analysis of the experimental conditions revealed that these particles were positively charged due to emission process, in contrast to most other experiments on the levitati...

Slow-moving (v ∼ 15 km/s) ‘dark matter particles’ have allegedly been discovered in a recent experiment. We explore the possibility that these slow moving dark matter particles are small mirror matter dust particles originating from our solar system. Ways of further testing our hypothesis, including the possibility of observing these dust particles in cryogenic detectors such as NAUTILUS, are a...

The work presents results of the characterization of dust collected in ASDEX Upgrade, with the special emphasis on size, morphology, structure and composition of the dust particles. The dust particles were collected after 2009 campaign using the filtered vacuum technique. The structure and composition of the particles were examined by scanning electron microscopy (SEM) combined with energy-disp...

Electrode sheath profile measurements are reported, with dust particles in suspension and without With the shape of the unperturbed potential profile, basic characteristics can be predicted as the surface potential, the charge and potential energy of a dust particle in function of its position in the sheath The dust particle screening length is also estimated analyzing binary collisions in a ga...

In the light of a case report, we will describe a hypothesis of the lymphatic transport mechanism of inhaled dust particles to the parietal pleura. The autopsy of a molder who had been employed for 41 years in iron foundries showed heavy mixed-dust pneumoconiosis. In the parietal pleura there were black linear streaks following the course of intercostal arteries. These formations were microscop...

Water scarcity is one of the factors limiting plant growth and development. More than onethird of the global terrestrial ecosystems is located in arid and semi-arid regions. The mostimportant limiting factor for plant growth is water shortage. Drought could significantlychange the natural vegetation cover. Rainfall reduction in Iraq, Turkey and Syria hasreduced vegetation cover so that dust sto...

[1] Triboelectric charging of saltating and colliding sand and dust particles produces strong electric fields in terrestrial dust devils and dust storms. Acceleration of the charged particles, as well as microdischarges between them, generates wideband electromagnetic radiation. Similar phenomena are expected to be ubiquitous on Mars, because Martian dust devils and dust storms are larger, stro...
