ANALYSIS OF THE EFFECT OF TUNGSTEN INERT GAS WELDING SEQUENCES ON RESIDUAL STRESS AND DISTORTION OF CFETR VACUUM VESSEL USING FINITE ELEMENT SIMULATIONS

The as-welded sectors of China Fusion Engineering Testing Reactor (CFETR) vacuum vessel (VV) have very tight tolerances.However, it is difficult to investigate the welding stress and distortion without the production of a full-scale prototype.Therefore, it is important to predict and reduce the welding stress and distortion to guarantee the final a

The major progress made in the identification EspressoCover of the molecular bases of mitochondrial disease has revealed the huge diversity of their origin.Today up to 300 mutations were identified in the mitochondrial genome and about 200 nuclear genes are possibly mutated.In this review, we highlight a number of features specific to mitochondria

Abstract Background Orthodontic tooth movement (OTM) is a dynamic equilibrium of bone remodeling, involving the osteogenesis of new bone and the osteoclastogenesis of old bone, which is mediated by mechanical force.Periodontal ligament stem cells (PDLCSs) in the periodontal ligament (PDL) space can transmit mechanical signals and regulate osteoclas

The posture accuracy of full-body dynamic simulation has been successfully evaluated in JACK Siemens software via analyzing Guide Rod Plug two common push and pull tasks.The difference in joint angles between the actual and predicted human movement directly results in the strength of force exposed on the lumbar spine.In this study, the individual f

To increase the commercial value of damaged fragrant pears and improve marketing competitiveness, this study explored the degree of damage degree and effects of storage time on the internal quality of fragrant pears during storage and predicted the internal quality of fragrant pears using an adaptive neural fuzzy inference system (ANFIS).The intern
