The present work investigates γ-channel dislocation reactions, which govern low-temperature (T = 750 °C) and high-stress (resolved shear stress: 300 MPa) creep of Ni-base Visors single crystal superalloys (SX).It is well known that two dislocation families with different b-vectors are required to form planar faults, which can shear the or
A new fossil site was discovered Mule Tape Halters in the Rising Star Cave in 2013 in the Cradle of Humankind in South Africa.This site which has yielded 1550 hominin bones so far is considered to be one of the richest palaeoanthropological sites in the world.The deposition of the fossils in a remote part of the cave system, approximately 100 m fro
Desert vegetation is undergoing complex and diverse changes due to global climate change and human activities.To effectively utilize water resources and promote ecological recovery in desert areas, it is necessary to clarify the main driving mechanisms of vegetation growth in these regions.In this study, based on MODIS and Landsat 8 remote sensing
Introduction The authors developed and evaluated a faculty development program on clinical teaching skills to address barriers to participation Epilobium and to impact teaching behaviors.Methods Four one-hour workshops were implemented over five months.Evaluation included participant satisfaction and pre/post self-assessment.Pre/post faculty teachi
In this paper, design and simulation of a deployment and release mechanism of a communication satellite antenna are described.Because of the simplicity and reliability of the system, a torsion spring is used to excite the antenna.Dynamic simulation is performed by Adams Software and the appropriate spring and damper are selected for the mechanism.A
