Soviet experience of underground coal gasification focusing on surface subsidence [PDF]
, 2015 Global coal mining activity is increasing due to demands for cheap energy and the availability of large coal deposits around the world; however, the risks associated with conventional coal mining activities remain relatively high.

CULPA E MÁ CONSCIÊNCIA EM NIETZSCHE E FREUD
Revista de Filosofia, 2005 Parte-se das interrogações de Nietzsche e de Freud sobre a agressividade do animal homem. Pela via da epistemologia francesa, procura-se colocar essas interrogações no solo comum do nascimento das ciências da vida.

Self-learning Multiscale Simulation for Achieving High Accuracy and High Efficiency Simultaneously
, 2009 We propose a new multi-scale molecular dynamics simulation method which can achieve high accuracy and high sampling efficiency simultaneously without aforehand knowledge of the coarse grained (CG) potential and test it for a biomolecular system. Based on

Sensitivity analysis on UCG–CCS economics
International Journal of Greenhouse Gas Control, 2014 Abstract Underground coal gasification (UCG) facilitates the utilization of deep-seated coal seams that are economically not exploitable via conventional mining. A techno-economic model was developed to examine UCG cost effectiveness converting coal into a synthesis gas to fuel a combined cycle gas turbine power plant (CCGT) with subsequent CO2 ...

MODELING OF MATERIAL BALANCE FROM THE EXPERIMENTAL UCG
Acta Polytechnica, 2020 The underground coal gasification is a continually evolving technology, which converts coal to calorific gas. There are many important parameters in this technology, which are difficult to measure. These parameters include the underground cavity growth, amount gasified coal, and the leakage of input and output gaseous components into the surrounding ...

Effect of Particle-Hole Asymmetry on the Mott-Hubbard Metal-Insulator Transition
, 2004 The Mott-Hubbard metal-insulator transition is one of the most important problems in correlated electron systems. In the past decade, much progress has been made on examining a particle-hole symmetric form of the transition in the Hubbard model with ...
