In order to deeply understand the influence of driving position of vibrating flip-flow screen on motion characteristic of main and floating screen frame, mechanical model and vibration differential equation of the vibrating flip-flow screen were established with consideration of the effect of damping.The formulas of amplitude and phase of main and
In METAL DETOX this work we prove the existence of global weak solutions to a degenerate and strongly coupled parabolic system arising from the transport processes through partially saturated deformable porous materials.The hygro-thermal model is coupled with quasi-static evolution equations modeling elastic and inelastic mechanical deformations.Ph
During the Russian-Turkish war of 1787-1791 the fortress on the Danube were major military bases for the Turkish Planner army.They are reliably protected the Balkans against the invading Russian troops.Based on studies of the memoirs of contemporaries and predecessors in this article refers to the importance of seizing the Turkish fortifications on
Lake sediments are a valuable archive to document past flood occurrence and magnitude, and their evolution over centuries to millennia.This information has the potential to EXTRA BODY DAILY SHAMPOO greatly improve current flood design and risk assessment approaches, which are hampered by the shortness and scarcity of gauge records.For this reason,
Background and Aim:Regardless of the positive economic effects, the adverse environmental impacts of mines make it necessary to assess environmental impacts.The purpose of this study was to determine the environmental impacts of granite and marble quarries in Khorasan Razavi province.Materials and methods:In this descriptive-analytical study after
