The hydraulic transmission engineering vehicle has the phenomenon of wheel eccentric load in the driving process, which seriously affects its safety.Therefore, a dynamic model of engineering vehicle considering the transmission system is established in SIMPACK software.The variation of wheel eccentric load with driving torque and its effect on whee

The internal microstructure of coal directly affects the mechanical properties and seepage properties of coal.It is the internal factor that induces coal and gas outburst, water damage, spontaneous combustion and other disasters.It is very important to analyze the microstructure of coal and its interaction with the permeability property.Among many

Extraction process of wood raw materials, from forest stand to the nearest forest road, is very difficult and expensive stage having highest environmental damages.Forestry activities where limited to the use of technology have great importance in terms of technical, economical, ergonomic and environmental in mountainous terrain especially.The aim o

Thresholds can be an effective tool in conservation planning, as they can form a defensible target for habitat conservation or restoration.Generalized thresholds must be used with caution, however, as threshold responses may vary with species and spatial scale.The objectives of this study were to identify Boxers the scales at which forest-dwelling

International research attention on evacuation issues has increased significantly following the human and natural disasters at the turn of the century, such as 9/11, Hurricane Katrina, Cyclones Idai and Kenneth, the Black Saturday forest fires and tsunamis in Japan.The main problem concerning when a disaster can occur involves studying the risk red
