NoiseModelling is a free and open-source tool designed to produce environmental noise maps on very large urban areas. It can be used as a Java library or be controlled through a user friendly web interface.

NoiseModelling is closely paired with the spatial database H2GIS or PostGIS in order to handle a large amount of spatial features. In addition to the operational aspect, this tool is an excellent support for training, teaching and research.

The Nalco Guide To Boiler Failure Analysis Hit

Send a sample for SEM/EDS analysis. The NALCO Guide provides the baseline micrographs. If your lab report matches Figure 7-12 in the NALCO Guide (Hydrogen Damage Fissuring), you have achieved your definitive “hit.”

This is where NALCO’s expertise shines. The famous flow-assisted corrosion (FAC) charts and caustic corrosion diagrams allow analysts to pinpoint exact pH ranges. For instance, a "hit" shows a smooth, scalloped surface, whereas acidic corrosion leaves a sharp, jagged edge. The guide provides micrographs that allow a field engineer to make a lab-quality identification.
