To investigate the effect of the molecular structure of nitrogen compounds on the CO and NO emissions from experiments conducted in a bench-scale BFBC (bubbling fluidized-bed combustor), feed materials are prepared by mixing the model compounds (including pyridine, pyrrole, quinolone, aniline,...

It is now well known that the principles of innovation for the Bottom of the Pyramid (BOP) markets are different from those of the top of the pyramid. This paper discusses these principles taking the example of the development of a rural domestic water filter in India. Work related to two...

An acid-catalyzed TEOS system has gelated under four different solvent evaporation conditions, and the singularity spectra of the resultant xerogels have been determined with image analysis methods and discussed in combination with their mesoporosity values. Generally, larger scale of...

The soil frequently is fragile and has low stability in heavy loading. The objective of this study is to review the stabilization of soil using sustainable methods. Some strengthening approaches are available for stabilization of expansive soils. These methods consist of stabilization with soil...
