Special issue “Understanding phreatic eruptions - recent observations of Kusatsu-Shirane volcano and equivalents -”

Eruptions of the st. Augustine volcano: airborne measurements and observations.

Airborne measurements of the effluents from the St. Augustine volcano obtained during a 10-day period of activity showed that aerosol was ejected at the rate of about 10(5) kilograms per second during brief eruptions (3 to 8 minutes). Steadier emissions contained much more water vapor and gaseous sulfur but less aerosol mass. A nuée ardente (glowing avalanche) produced by one eruption reached a...

Evidence for Recent Large Magnitude Explosive Eruptions at Damavand Volcano, Iran with Implications for Volcanic Hazards

Damavand is a large dormant stratovolcano in the Alborz Mountains of northern Iran located in one of the most populous provinces, which could be adversely affected by tephra fall from Damavand. The youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. The volcanic products are predominantly porphyritic trachyandesite. Three major young pumice deposits, named here a...

Special Issue on Recent Developments of Nanofluids

Recent advances in nanotechnology have allowed the development of a new category of fluids termed nanofluids. A nanofluid refers to the suspension of nanosize particles, which are suspended in the base fluid with low thermal conductivity. The base fluid, or dispersing medium, can be aqueous or non-aqueous in nature. Typical nanoparticles are metals, oxides, carbides, nitrides, or carbon nanotub...

Special issue editorial: Understanding software ecosystems

The term business ecosystem was originally established more than 20 years ago. In the seminal article ''Predators and prey: a new ecology of competition'' [1], Moore proposes an ecological approach to explain the co-evolution of companies within a business ecosystem by adopting a complex interplay of cooperative and competitive strategies. According to Moore, business ecosystems evolve in four ...
