As the gas industries in the United States and Japan switched from toxic coal gas to nontoxic natural gas, the incidence of accidental deaths from domestic gas declined dramatically in both nations. Thus, improvements in public health occurred as incidental side effects of business decisions.

β¦ Synopsis
Specific-pathogen-free swine were produced under field conditions in a high emission exposure area and a low emission exposure area of a natural gas processing plant over a period of 38 too. Production parameters were measured and respiratory tissues sampled. Sulfur dioxide concentration was monitored in the high exposure area. Average concentrations of SO2 exceeded 0.20 ppm for 30 min on 23 occasions during one of four rate of gain and feed conversion trials. Average concentrations of S Q exceeded 0.02 ppm for 24 hr on 5 days when farrowings occurred. No significant difference was found in rate of gain, feed conversion, piglets born per litter or piglet survival, between swine produced in the two areas. No histological alterations such as loss ofcitia, atrophy of goblet cells or cellular metaplasia were observed in any respiratory epithelia from 62 pigs.

Fuel consumption and emissions of a specific tractor engine depend mainly on engine speed and torque. The engine load can be influenced by alternative driving techniques, by the design of the drive train and by use of implements with different work capacities. This work deals with the effects of var
In this paper, a novel process for the production of pure hydrogen from natural gas based on the integration of solid oxide fuel cells (SOFCs) and solid oxide electrolyzer cells (SOECs) is presented. In this configuration, the SOFC is fed by natural gas and provides electricity and heat to the SOEC,
