Contact bedding material is an important environmental Crank Disk factor and welfare creator for laboratory mice.It can alter important physiological process and create potential chance for experimental variation which puts hurdle for comparability.The present experiment was conducted to assess the possible impact of different types of bedding mate
The distribution of pores and skeletons within coal reservoirs significantly affects the migration of gases and the occurrence of gas dynamic disasters.To further explore the micro-damage mechanisms in gas-containing coal, a detailed study of the micro-damage process in gas-containing coal was conducted.Atomic force microscopy was employed to condu
Smart city is an area where the Internet of things is used effectively with sensors.The data used by smart city can be collected through the cameras, sensors etc.Intelligent video surveillance (IVS) systems integrate multiple networked cameras for automatic surveillance purposes.Such systems can analyze and monitor video data and perform automatic
Sulfur and phosphorus additives are used in lubricants as extreme-pressure and antiwear agents, which are typically used together to ensure reliability over a wide range of lubrication conditions.However, the working mechanism of the combined additive system has not been clearly defined due to difficulties obtaining information on the material surf
Abstract An early corrosion failure of the piping system of a gas heater was reported by a gas complex company.Local corrosion rates of 0.90 and 0.66 mm/year were observed in the heater piping system.An investigation including visual examination, macrostructure, microstructure (SEM, EDS and XRD), thickness gauging, chemical analysis, and mechanical
