The company specializes in custom solutions across fire detection, security, access control, and video surveillance. “After seeing a ZeroEyes demo presented by an existing EPS client, I instantly knew we needed it as an additional layer of protection,” said Connie Altier, Superintendent of TCCC...
It consisted mainly of two steps: (i) assessment of the fire damage by field surveys and remote sensing techniques; and (ii) geotechnical laboratory tests to characterize the undisturbed soil samples. Figure 2. Workflow used to analyze the fire effects on the topsoil physical properties (CBI, ...
impacts of a wildfire on the physical proper- ties, specifically soil structure, water repellency, and thermal capacity, as well as thermal conductivity of a typical sandy soil of the Eastern Sierra Nevada mountains under conifer forest vegetation, using the Caldor fire as an example (Figure 1A)...
A minimum of 3 test runs were performed for every analysis, and the average of the two closest results (less than 5% variation) was taken as the measured value. 2.2.3. Ultimate Analysis The elemental composition of the biomass with respect to carbon (C), hydrogen (H) and nitrogen (N) ...
The test was conducted based on ASTM D471 where toluene liquid was chosen as the swelling agent. The test was carried out at room temperature. For the first 22 h of immersion, the weights of each specimen were taken for every two hours. The immersion was then continued for another 48 h ...
Additionally, human activities such as deforestation of slopes, removal of slope support in road cuts, alteration of surface runoff paths, have become important triggers for landslide manifestation [10,11]. Every year, landslides kill people and cause huge property damage in mountainous areas of ...
