APPLICABILITY OF CONVEX AND CONCAVE SHAPED SURFACE TEXTURING TO IMPROVE DAMPING PERFORMANCE OF MECHANICAL TENSIONER FOR TIMING CHAIN OF INTERNAL COMBUSTION ENGINE

The present study describes an improvement of damping performance of a mechanical tensioner driven by friction force at the power spring interface, used for the timing chain system for an internal combustion engine.The mechanical tensioner consists of a power spring subjected to face-to-face contact with a reciprocal motion and a leaf spring to app

Introduction: The current gold standard for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnosis by real-time reverse transcriptase polymerase chain reaction (RT-PCR) is limited by the number of genes that can be detected.In this study, we developed a low-cost and high-throughput next-generation sequencing technology that can over

Useof a vehicle involves a risk of collision and,consequently,high costs of post-accident repairs.Therefore, if there is no insurance cover and the repair must be paid by the vehicle owner, some of them choose to file fraudulent insurance claims as the damage can be very difficult to verify.Payments of undue damages pose a majorsocial and economic
