Investigation of a Liquefaction Methodology to Enable the Utilization of In-Situ Produced Propellant on the Lunar and Martian Surfaces [PDF]

open access: yes
To enable NASAs plans to return astronauts to the lunar surface and eventually to Mars, the agency is putting emphasis on reusable cryogenic systems. Such systems will require replenishing of cryogens on-orbit via a cryogenic tanker or refueling depot ...

Coal liquefaction

open access: yesApplied Catalysis, 1983
This general paper reviews Canadian programs in Coal Liquefaction research, development and economic assessment. The current "state of the art" of coal liquefaction technology is seen to be unlikely to offer immediate prospects for implementation during a period when crude oil supply costs are below $ 45 per barrel.

Study on the Empirical Probability Distribution Model of Soil Factors Influencing Seismic Liquefaction

open access: yesBuildings
One of the important tasks in sand liquefaction assessment is to evaluate the likelihood of soil liquefaction. However, most liquefaction assessment methods are deterministic for influencing factors and fail to calculate the liquefaction probability by ...

Preconditioning and triggering of offshore slope failures and turbidity currents revealed by most detailed monitoring yet at a fjord-head delta [PDF]

open access: yes, 2016
Rivers and turbidity currents are the two most important sediment transport processes by volume on Earth. Various hypotheses have been proposed for triggering of turbidity currents offshore from river mouths, including direct plunging of river discharge,

Overview geotechnical model tests on dike safety at Deltares [PDF]

open access: yes, 2012
Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed.
