the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

This pilot study of a school-based telepractice pilot project in a rural, remote county of North Carolina investigated the satisfaction of parents/caregivers, teachers, and administrators with a year-long telespeech therapy program delivered by a university clinic. Upon completion of the almost year-long project, a satisfaction survey incorporating a 5-point equal-appearing Likert scale (1= str...

In the face of growing oil demand the use of renewable feedstocks for the potential to supply transportation fuels, electricity, chemicals and materials is increasingly attractive. This review covers novel technologies and pathways to produce liquid fuels and chemical intermediates in an efficient and cost-effective way. Several commercial and pilot scale projects by companies including Anellot...

A small group of heavy vehicle drivers underwent an ecodrive training course. Their driving was assessed for various ecodrive variables as they completed an 18 mile circuit in normal traffic immediately after the course and again 6 and 12 weeks later. Compared to pre-course measures, these drivers reduced their fuel consumption by an average of 27%, the number of gear changes by 29%, and the nu...

A Rocket Based Combined Cycle combustor model is tested at a ground direct connected rig to investigate the flame holding characteristics with a small rocket exhaust using liquid kerosene. The total temperature and the Mach number of the vitiated air flow, at exit of the nozzle are 1505 K and 2.6, respectively. The rocket base is embedded in a fuel injecting strut and mounted in the center of t...

Emergy indicators of the industrial production and pilot-plant operation of Molten Carbonate Fuel Cells (MCFC) are presented, as a continuation of ongoing research on Hydrogen-based technologies. MCFCs are very likely to shortly reach the commercialization phase, as a result of the recent intense efforts in the development of innovative ceramic components (anode, cathode and matrix), as well as...

The Graz Cycle, a hydrogen oxygen fired double loop high temperature steam cycle, combining gas turbine philosophy with steam plant praxis, can be adapted for combustion of methane with oxygen. The resulting combustion products carbon dioxide and hydrogen oxide, i.e. high temperature steam, are mixed with cooling steam and expanded to lowest pressure and temperature. By condensing the steam, se...
