Metal abrasive particle content in lubricating oil is an important index to judge the degree of deterioration of lubricating oil. Established a spiral electrode capacitance sensor by the finite element software ANSYS, the simulation result shows that the sensor is sensitive to the content of metal abrasive particle in lubricating oil, not affect by the metal abrasive particle itself. According ...

Ozone is one of the most severe air pollution problems in the world. The concentration of ozone in the troposphere is of great interest because of its negative influence on the human health, vegetation and materials. The complexity of ozone (O3) formation mechanisms in the troposphere, the complexity of meteorological conditions in urban areas and the uncertainty in the measurements of all the ...

Environmental monitoring of environmental pollution prevention and control in humans to resolve existing or potential environmental problems and improve the living environment and the ecological environment, coordinating the relationship between human beings and the environment, and ultimately to sustainable human development plays an important role. In order to accurately and fully grasp the p...

Lichens are used as effective monitors to detect low-level air pollution which may affect different flora and fauna communities. Epiphytic lichens have been widely recognized as effective eco-friendly bio-monitors for detection of metal deposition on trees, rocks and bare ground. This article is concerned with the use of lichens in bio-monitoring of air pollution, how the lichens do recognize a...

a study of substantial anthropogenic related pollution in the coastal samut prakarn province (thailand) was carried out focusing on the bang pu nature reserve (remnant mangrove wetland) using a remote sensing (geospatial) technique. statistical regression models were developed between biochemical parameters of sample point and related reflectance data obtained from satellite imagery (landsat tm...

The paper presents an outline of the development of WiFi field monitoring maps using the Internet-of-Things (IoT) technology. The negative impacts of signals generated by the WiFi access points on health and measurement metrics are discussed. The experimental system for collecting WiFi signal data is presented. Finally, the construction of WiFi signal strength heatmap is discussed and some prel...

Pollution attack is known to have a disastrous effect on existing P2P infrastructures: it can reduce the number of legitimate P2P users by as much as 85%, and it generates abundant bogus data which may deplete the communication bandwidth. We propose a distributed defense and detection mechanism to resolve pollution attacks. The mechanism is composed of a set of “randomized” and “fully distribut...

Bacteriophages active against specific Bacteroides host strains were shown to be suitable for detection of human faecal pollution. However, the practical application of this finding is limited because some specific host strains were restricted to certain geographic regions. In this study, novel Bacteroides host strains were isolated that discriminate human and animal faecal pollution in Switzer...
