Landfill Gas to Energy This research investigates the utilization of landfill gas, an abundant waste product, by reforming it to syngas that can be converted to liquid fuels using Fischer Tropsch or to a H2 rich stream using water-gas shift. 65% of the 413 million tons of municipal solid waste (MSW) generated per year in the United States is landfilled, and 67% of the landfilled MSW is composed...

OBJECTIVE To develop a new composite disease activity score for gout and provide its first validation. METHODS Disease activity has been defined as the ongoing presence of urate deposits that lead to acute arthritis and joint damage. Every measure for each Outcome Measures in Rheumatology core domain was considered. A 3-step approach (factor analysis, linear discriminant analysis, and linear ...

We present high spatial resolution observations of the blue compact dwarf galaxy IZW 18 performed in the Hα line with a scanning Fabry-Perot interferometer at the CFH telescope. Morphological structure of the galaxy in Hα and in the red continuum is investigated. We also analyse the velocity field of the ionized gas. Besides the two compact HII components of the main body we find a population o...

This article discusses statistical models for solar flare interval distribution in individual active regions. We analyzed solar flare data in 55 active regions that are listed in the Geosynchronous Operational Environmental Satellite (GOES) soft X-ray flare catalog for the years from 1981 to 2005. We discuss some problems with a conventional procedure to derive probability density functions fro...

The continuous emission spectra of Hα, Hβ, and Hγ wave bands of the solar flare of 5 July 1989 have been analysed. We demonstrate that the flare not only emits at the line centres and wings of Hα, Hβ, and Hγ, but also in the continuum near these lines. The positions, durations, and configurations of the four flare kernels are respectively similar to those of a white light flare (WLF). Therefore...

Proton exchange membrane fuel cells (PEMFCs) with a dead-ended anode and cathode can obtain high hydrogen and oxygen utilization by a comparatively simple system. Nevertheless, the accumulation of the water in the anode and cathode channels might cause a local fuel starvation degrading the performance and durability of PEMFCs. In this study, a brand new design for a polymer electrolyte membrane...

A new method for the detection of indirect alkylating agents, such as the nitrosamines, using 3,4-dichlorothiophenol as t rapping agent in the presence of rat liver microsomes is reported. 3,4-Dichlorophenyl alkyl thioethers thus formed dur ing the incubation are detected by the use of a gas chromatography-mass spectrometry combinat ion unit and are quanti f ied by use of external standards. A ...
