The subject matter of this paper, if treated in the general sense, covers an extremely wide field to which it is impossible to do justice in the time allocated. It is even difficult to cover the subject adequately if we confine ourselves only to the furnace design of bagasse fired sugar mill boilers. I therefore intend to give a short summary of past and present bagasse furnace designs and cove...

During the last years, the aviation sector has been looking into alternatives to kerosene from crude oil, to combat climate change by reduction of greenhouse gas (GHG) emissions and to ensure security of supply at affordable prices. The efforts are also a reaction to commitments and policy packages. Currently, a wide range of possible fuel candidates and fuel blends are discussed in the triple ...

As alternative fuels compete with conventional fuels for a place in public awareness and acceptance, one of their most visible applications is in public transportation. Vehicles, particularly buses and shuttles, that carry people in large numbers, stand to gain much from using alternative fuels. Such high-demand fuel users can help sustain a fueling infrastructure that supports private autos an...

Emissions from two biofuels, a soy-based biodiesel and an animal-based biodiesel, were measured and compared to emissions from a distillate petroleum fuel oil. The three fuels were burned in a small (3.5x10 Btu/hr) firetube boiler designed for use in institutional, commercial, and light industrial applications. Emissions were measured for carbon monoxide (CO), carbon dioxide (CO2), oxides of ni...

Since 1970, vehicle’s exhaust pollutions have received increasing attention as a source of air pollution at both local (human health concerns) and global (global warming) scales. This study mainly discusses diesel and gasoline vehicles because, today, over 90% of vehicles on the road use gasoline and diesel fuels. The major concerns of gasoline exhaust contaminants are carbon monoxide (CO), hyd...

The intestinal epithelia rely on resident stem cells to undergo homeostatic growth as well as tissue repair upon injury. In response to insults elicited by pathological bacterial infection or tissue damaging chemicals such as dextran sodium sulfate (DSS), intestinal stem cells (ISCs) speed up their proliferation and differentiation to effectively replenish lost cells. Despite numerous studies, ...
