Synonymously referred to as dune buggies, a sandrail is a type of speciality vehicle. [1] They are popularly operated on actual sand dunes. Sandrails can be driven ...
Excited granular matter is a rich pattern-forming system. Some of the pattern-forming behaviours seen in granular materials are: The un-mixing or segregation of unlike grains under vibration and flow. An example of this is the so-called Brazil nut effect [10] where Brazil nuts rise to the top of a packet of mixed nuts when shaken. The cause of ...

The sand may be delivered by gravity, by a steam-blast (steam locomotives) or by compressed air.Gravity sanding requires that the sand be dry so that it runs freely. Locomotives use multiple sandboxes, so that their delivery pipes could be short and nearly ver
Open systems have input and output flows, representing exchanges of matter, energy or information with its surroundings. An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the ...
[5] [6] [7] Most examples of active matter are biological in origin and span all the scales of the living, from bacteria and self-organising bio-polymers such as microtubules and actin (both of which are part of the cytoskeleton of living cells), to schools of fish and flocks of birds.
