The typical U.S. refuse-to-energy facility utilizes a 600 psig, 750°F steam cycle. The ability to operate at higher steam pressure and temperature cycles, without incurring excessive corrosion, results in more kilowatts per ton of refuse and, hence, more economically at­ tractive projects. This paper represents the evolution of a 900 psig, 830°F refuse boiler from lower temper­ ature and pressu...

The Council on Medical Student Education in Pediatrics continues the series about skills of, and strategies used by great clinical teachers. Great clinical teachers recognize that many things influence students’ learning, including what they teach, how they teach, and where they teach. “Where” refers to the learning environment. Although the term “environment” may conjure visions of trees, snow...

Techniques were evaluated for formation of a liquid inoculum from shredded municipal refuse, including chilling the refuse at 4 degrees C prior to blending and multiple washing and blending cycles. The average count of cellulolytic bacteria from six different detachment treatments was 5.1 x 10 cells per g (dry weight) of refuse with a range of 0.7 x 10 to 12.7 x 10 cells per g (dry weight). The...
