Voltage sag is considered to be one of the most serious hazards of power quality and can produce a harmful effect on electrical power system stability and most electronic devices such as personal computers, programmable logic controllers and variable speed drives. At the same time, Distributed Gener...
The five domains include human resettlement and the carrying capacity of the environments (especially land), water quality, reservoir sedimentation and downstream riverbed erosion, soil erosion, and seismic activity and geological hazards. It concludes with a discussion of the lessons that can be ...
The durable construction ensures that the toys can withstand the rough and tumble of active play, while the absence of batteries means that children can enjoy the toys without the risk of electrical hazards. The set is also designed with safety in mind, featuring a warning to keep away from ...
measure pH and electrical conductivity (EC) of the soil in a 1:5 soil/water suspension. Physicochemical properties were also measured in a soil sample without amendment (termed control). Maintaining water saturation in soils from 70 to 80% was carried out using the method of Blaylock et al....
If appropriate measures are not taken to prevent ESD damage, the hazards caused by ESD include but are not limited to degradation of integrated circuit performance or complete damage of integrated circuit. For some precision integrated circuits, a very small parameter change may cause the whole ...
Landslide is one of the most serious geological disasters. Finding out the morphological characteristics of landslide and the formation mechanism of landslide is of great significance to landslide stability analysis, risk management of landslide hazards and government decision-making. Previous studies on la...
This product solves the problem of safety hazards when circuit breakers or fuses are used as SPD backup protection. SPDSCB is suitable for 50/60Hz, 400V below TT, TN and other power supply systems, with lightning fow outdated without false trip; SPD...
As China is planning to start to build S-PHS projects recently, it is high time to assess the overall risks level of the S-PHS plant, choose an effective management mode and provide risk response strategies to reduce economic losses and environmental hazards and further promote its smooth devel...
