Assessing future vent opening locations at the Somma-Vesuvio volcanic complex: 1. A new information geodatabase with uncertainty characterizations

Numerical simulations of volcanic jets : Importance of vent overpressure 1

Changes in microbial communities in coastal sediments along natural CO2 gradients at a volcanic vent in Papua New Guinea.

Natural CO2 venting systems can mimic conditions that resemble intermediate to high pCO2 levels as predicted for our future oceans. They represent ideal sites to investigate potential long-term effects of ocean acidification on marine life. To test whether microbes are affected by prolonged exposure to pCO2 levels, we examined the composition and diversity of microbial communities in oxic sandy...

Assessing Future Traveller Information Systems

Future traveller information systems (FTIS) supported by pervasive computing are being considered as the next generation of traveller information systems. However, large scale deployments of pervasive computing environments do not yet exist. Building models or mockups of FTIS is expensive and time-consuming. This paper introduces current research at Newcastle University which is investigating t...

Assessing the Behavioral Reaction of Investors to the Price Change Using the Speed of Price Adjustment Approach to the General Information and Its Relation with Future Return

In Recent Decades, The Financial Sphere has entered a New Era of Contempt for Some of the Assumptions of Modern Economics and Finance. One of These Assumptions is the Rationale of the Investors, which has been Seriously Challenged and Is Now Being Strengthened by the Fact That Prices are Determined more by Attitudes and Psychological Factors than for Fundamental Variables and Therefore the Stud...

Numerical simulations of volcanic jets: Importance of vent overpressure

[1] Explosive volcanic eruption columns are generally subdivided into a gas-thrust region and a convection-dominated plume. Where vents have greater than atmospheric pressure, the gas-thrust region is overpressured and develops a jet-like structure of standing shock waves. Using a pseudogas approximation for a mixture of tephra and gas, we numerically simulate the effects of shock waves on the ...
