Observations of flowing granular matter have suggested that same-material tribocharging
depends on particle size, typically rendering large grains positive and small ones negative …

We present the design and performance characterization of a new experimental technique
for measuring individual particle charges in large ensembles of macroscopic grains. The …

Recent observations endorse earlier measurements of time varying electric and magnetic
fields generated by tornadoes and dust devils. These signals may provide a means for early …

Synoptic and mesoscale analyses indicate environmental conditions favorable to the
development of tornados and downbursts in Eastern São Paulo State, Brazil, between 16 …

Electrostatic charge accumulation in a gas–solid fluidized bed is considered an adverse
effect. However, with the presence of an external electrical field, we can take advantage of …

Significant progress has been made in forecasting hazardous atmospheric events such as
catastrophic and severe tornadoes (level EF3-EF5). A method for nonstochastic long-term …

Granular materials include a large variety of materials. Their only defining characteristic is
that they are composed of large agglomerations of macroscopic particles [1]. Sand, corn …

Sandstorms are frequently accompanied by intense electric fields and lightning. In a very
narrow region close to the ground, sand particles undergo a charge exchange during which …

It is inferred from the phenomenological facts of tornado that tornado itself should have a
driving force generating the updraft in the vortex of tornado. The driving force is supposed to …

Neoconservatism is a political philosophy that emerged in the United States. Its key
distinction is in international affairs, where it espouses an interventionist approach that …
