Figure 1.The Theoretical Changes in Biomechanics With Stent Deployment With Both MPS and BVS.Curved vessels undergo straightening with MPS,resulting in disturbed flow and higher circumferential outward stress at stent edges (red arrows) and greater plaque prolapse at the lesion.Stent deployment with the more conformable BVS results in more laminar flow and lower outward stress (white arrows).The Effect of Framework Design on Stress Distribution in The finite element method (FEM) has been shown to be a useful tool when investigating complex systems.7,8 Knowledge of stress distribution is important in the understanding of fatigue yielding.9 Overall stress distribution within the tooth/restoration complex is determined by geometry and hard tissue/restorative material arrangement.10 It TECHNOLOGY OF HEAT TREATING-STRAIGHTENING OFaxial force is generated that,acting on the semi-finished product,causes its axial straightening.The fixture was a rigid tube of steel C25,with ap-ertures for the coolant.The clamps were installed at the ends of the fixture.In the process under analysis,the concept of quality straightening is taken to mean such

The result obtained from the clinical and histomorphometric study is that bone loss occurred in the implant neck is an important parameter in implant loss during the postloading period.[29,30,31] A possible reason for this result is an uneven distribution of stress in the bone socket and exposure to maximum stress in the bone implant neck.In Effects of shear stress on microalgae - A reviewCultivation of microalgae requires consideration of shear stress,which is generated by operations such as mixing,circulation,aeration and pumping that are designed to facilitate mass and heat transfer as well as light distribution in cultures.Excessive shear stress can cause increased cell mortaContact Stresses and DeformationsSpheres in Contact Vertical Stress Distribution at Center of Contact Area Plot shows material with Poissons ratio = 0.3 0.5aa1.5a2a 2.5a 3a z X, y max 0 , z Von Mises 0 0.2 0.4 0.6 0.8 1 Depth below contact area R a ti o of s tress to p ma x The maximum shear and Von Mises stress are reached below the contact area
