The dual-fuel diesel engine (D.F.D.E) is a conventional diesel engine in which much of the energy released, hence power, comes from the combustion of gaseous fuel such as natural gas. The exhaust emission characteristics of the D.F.D.E needs further refinements, particularly in terms of reduction of Unburnt Hydrocarbons (U7HC) and Carbon Monoxide (CO) emission, because the concentration of thes...

Regenerative Thermal Oxidizer (RTO) is one of the best solutions for removal of Volatile Organic Compounds (VOC) from industrial processes. In the RTO, VOC in a raw gas are usually decomposed at 950-1300 K and the combustion heat of VOC is recovered by regenerative heat exchangers charged with ceramic honeycombs. The optimization of the treatment of VOC leads to the reduction of fuel addition t...

A pilot-scale unitized reversible fuel cell (URFC) system was installed in our laboratory (AIST) and its efficiency was comprehensively evaluated. This URFC system was composed of a proton exchange membrane (PEM)-based cell/stack and balance of plant (BOP) adaptable for both electrolysis (EL) and fuel cell (FC) operationmodes. First, the efficiency of this URFC system was evaluated at both the ...

The Autonomous Formation Flight (AFF) project at the NASA Dryden Flight Research Center (Edwards, California) investigated performance benefits resulting from formation flight, such as reduced aerodynamic drag and fuel consumption. To obtain data on performance benefits, a trailing F/A-18 airplane flew within the wingtip-shed vortex of a leading F/A-18 airplane. The pilot of the trail airplane ...

Teaching planning and decision making in agricultural systems at universities is often theoretically with few practical examples. Regularly there are not enough possibilities to get experience in planning a whole farm business having regard to all enterprises and all kinds of farm planning (production plan, financial plan,...). Making plans of separate parts of the farm without regarding the wh...

1. Auriculotherapy was effective in relieving the symptoms of constipation and improving quality of life for elderly people. 2. Auriculotherapy had a significant time effect in relieving symptoms of constipation, a greater reduction in scores for symptoms of constipation and quality of life, and an increased number of bowel movements per week, compared with controls. 3. The methodology of this ...

Task management (TM) is always performed on the flight deck, although not always explicitly, consistently, or rigorously. Nowhere is TM as important as it is in dealing with non-normal situations. The objective of this study was to analyze pilot TM behavior for non-normal situations. Specifically, the study observed pilots’ performance in a full workload environment in order to discern their TM...

Post-consumer carpet represents a high volume, high energy content waste stream. As a fuel for co-firing in cement kilns, waste carpet, like waste tires, has potential advantages. Technological challenges to be addressed include assessing potential emissions, in particular NO emissions (from nylon fiber carpets), and optimizing the carpet feed system. This paper addresses the former. Results of...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the western Atlantic—the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to differentiate at sea; therefore, some of the descriptive material below refers to Globicephala sp., and is identified as such. The species is considered ...

The Essentials of Baccalaureate Education for Professional Nursing Practice provides a framework for building the baccalaureate education for the twenty-first century. One of the exemplars included in the essentials toolkit includes student participation in an actual root cause analysis (RCA) or failure mode effects analysis. To align with this exemplar, faculty at the University of Michigan Sc...
