Maintain a high level of integrity and reliability of pipelines for oil and gas pipeline industry is essential.Due to various reasons,there will lead to the pipeline failure.Among them,pipeline defect is the main reason to the failure of itself.And dent defect is one of the general defect types.Therefore,it is necessary to conduct a further sweet l
This paper discusses the resilience of the UAV quadrotor to wind disturbances.An unknown input-state observer is presented that uses sweet life carts the Lipschitz method to estimate the internal states and disturbances of the quadrotor and compensate for them by varying the velocities of the four rotors.The observer intends to use existing sensor
Three deep exploration wells in the Palmyride area (Syria) have beendrilled through Oligocene and Eocene deposits.A detailed micropalaeontological investigation has been performed on the planktonic foraminiferal assemblage from drill cuttings.Standard planktonic foraminiferal zones from P15 to P22 (E15 to O6) have been identified.The
Cell-based technologies galaxy buds skin are used as a therapeutic strategy in spinal cord injury (SCI).Mesenchymal stem cells (MSCs), which secrete various neurotrophic factors and cytokines, have immunomodulatory, anti-apoptotic and anti-inflammatory effects, modulate reactivity/phenotype of astrocytes and the microglia, thereby promoting neurore
