2 ABSTRACT A model for the chemistry in a plasma fuel reformer or plasmatron has been developed. The plasma fuel reformer is set up to produce syngas (hydrogen and carbon monoxide gas mixture) from partial oxidation of hydrocarbons. The behavior of methane as fuel has been investigated to characterize and simulate the plasmatron performance. The goal of this work has been improved understanding...

Compact reformers (CRs) are promising devices for efficient fuel processing. In CRs, a thin solid plate is sandwiched between two catalyst layers to enable efficient heat transfer from combustion duct to the reforming duct for fuel processing. In this study, a 2D heat and mass transfer model is developed to investigate the fundamental transport phenomenon and chemical reaction kinetics in a CR ...

An elderly patient with nodular regenerative hyperplasia of the liver and hypothyroidism who presented with life-threatening bleeding from oesophageal varices is discussed. Progress has been uneventful following a semi-emergency portocaval shunt 5 years ago with no evidence of hepatic encephalopathy. This is presumably a tribute to the relatively well-preserved hepatic function in this condition.

A model for pressurised steam/O2-blown fluidised-bed gasification of biomass with catalytic reforming of hydrocarbons and tars was developed using Aspen Plus simulation software. Seven main blocks were used to model the fluidised-bed gasifier and two for the catalytic reformer. Modelling blocks were complemented with FORTRAN subroutines to simulate the observed non-equilibrium behaviour of the ...

A method of active vibration control using regenerated vibration energy, i.e., the self-powered active vibration control is proposed. In this system, vibration energy is regenerated with an electric generator ,which is called energy regenerative damper, and is stored in a condenser. An actuator attains active vibration control using the energy stored in the condenser. A variable resistance is u...

Background: There is a worldwide effort to present novel approaches for the development of tolerance-induction treatments in regenerative medicine, after years of investigation in clinical transplantation. Particularly, novel approaches are based on controlling the immune response, including the application of biomaterials or imitation of antigen-specific peripheral tolerance in either solid-or...
